by Peter Reutemann 18 May '15

18 May '15

'The first smart TVs powered by Firefox OS have gone on sale in Europe. Panasonic's line of Viera smart TVs includes six that are powered by Firefox OS — CR850, CR730, CX800, CX750, CX700 and CX680 — including their first curved LED LCD TV. The full global launch of the TVs is expected “in the coming months.” From the Mozilla blog: "We’re happy to partner with Panasonic to bring the first Smart TVs powered by Firefox OS to the world,” said Andreas Gal, Mozilla CTO. “With Firefox and Firefox OS powered devices, users can enjoy a custom and connected Web experience and take their favorite content (apps, videos, photos, websites) across devices without being locked into one proprietary ecosystem or brand.”' -- source: http://news.slashdot.org/story/15/05/18/0213238 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174 http://www.data-mining.co.nz/

Venom VM bug called “perfect” for NSA, or for stealing bitcoins and passwords
by Peter Reutemann 13 May '15

13 May '15

"The just-patched critical vulnerability in widely used virtualization software is an ideal exploitation target for state-sponsored spies and criminals alike fishing for passwords, cryptography keys, or bitcoins, a researcher who has dissected one of the fixes said. The bug, which is known to affect the Xen, KVM, and native QEMU virtual machine platforms and appliances, makes it possible for attackers to break out of protected guest environments and take full control of the operating system hosting them, security researchers warned Wednesday. In the hours following Wednesday morning's disclosure of the vulnerability, many security professionals have publicly said its severity is being exaggerated. The critics have rightly pointed out that it can't be remotely exploited and can't be exploited on large numbers of machines in a single stroke, as is the case with most serious security bugs." -- source: http://arstechnica.com/security/2015/05/venom-vm-bug-called-perfect-for-nsa… Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174 http://www.data-mining.co.nz/

Tails 1.4 released

13 May '15

'Tails, The Amnesic Incognito Live System, version 1.4, has been released. The new version of the Debian-based live disc offers users a number of new features, including an updated copy of the Tor Browser and the Tor anonymity software has been upgraded to version 0.2.6.7. Tails 1.4 also ships with Paperkey, a program which allows users to print physical copies of their security keys. "Tor Browser 4.5 now has a security slider that you can use to disable browser features, such as JavaScript, as a trade-off between security and usability. The security slider is set to low by default to provide the same level of security as previous versions and the most usable experience. We disabled in Tails the new circuit view of Tor Browser 4.5 for security reasons. You can still use the network map of Vidalia to inspect your circuits. Tails OpenPGP Applet now has a shortcut to the gedit text editor, thanks to Ivan Bliminse. Paperkey lets you print a backup of your OpenPGP secret keys on paper."' -- source: http://distrowatch.com/?newsid=08941 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174 http://www.data-mining.co.nz/

Ubuntu 15.04 review: Beauty or “boring” is in the eye of the beholder
by Peter Reutemann 06 May '15

06 May '15

'Snow melts and trees blossom, but nothing really says spring around the Ars Orbital HQ like the arrival of a new version of Ubuntu Linux. Right on schedule, Canonical has recently released Ubuntu 15.04, also known as Vivid Vervet. Ubuntu 15.04 arrived in late April and has, judging by other reviews, largely underwhelmed. According to the popular storyline, there's not much new in 15.04. Of course, a slew of changes and unforeseen features in 15.04 could have just as easily earned a negative reaction, probably from the same people calling the actual release boring. The top of the Linux mountain is a lonely, criticism-strewn place. The truth is, this line of thought is partially correct. There isn't much new in 15.04, at least not in terms of visible changes to the Unity desktop. But for most users this is a good thing—change doesn't mean better. Frankly, Ubuntu 15.04's Unity desktop is mature, stable, and not really in need of many improvements. There are still some design inconsistencies (mostly GTK3 issues) and small problems here and there, but for the most part 15.04 delivers a great desktop experience. Those clamoring for big changes will have to wait. But more than likely, when those seismic shifts coming in Unity 8 arrive around this time next year, these same people will be reminiscing fondly about 15.04. Everyone will forget they once found this release "boring."' -- source: http://arstechnica.com/information-technology/2015/05/05/ubuntu-15-04-revie… Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174 http://www.data-mining.co.nz/

Hard Drive Failure Rates
by Lawrence D'Oliveiro 28 Apr '15

28 Apr '15

BackBlaze have been frequently posting notes on their experience with running large numbers of hard drives in their storage service. Some salient points: * “Enterprise” drives, while more expensive than “consumer” ones, are not significantly more reliable. (This has been borne out by other studies.) * Keep your drives running all the time, or switch them off when not in use? “Our vote is to keep them running.” * They do use SMART to keep an eye on their drives. Other studies I read reported that these only picked up a minority (around 30%) of failures, from which I concluded that SMART was not worth using. I suppose it’s different for these guys if it saves on costs to replace a drive *before* it actually starts reporting uncorrectable errors... <https://www.backblaze.com/blog/hard-drive-stats-faq/>

The March Of (In)Security
by Lawrence D'Oliveiro 25 Apr '15

25 Apr '15

Bruce Schneier has said “Today's top-secret programs become tomorrow's PhD theses and the next day's hacker tools”. And not long after that, a graduate homework assignment. The NSA was desperate to prevent any exposure of its top-secret “QUANTUM” packet-injection technology. But all this effort was futile, because others had already invented the same thing, including China’s “Great Cannon”, which was used to attack GitHub recently. The only protection is end-to-end encryption. <https://www.schneier.com/blog/archives/2015/04/the_further_dem.html>

X2Go: An Open Source Remote Desktop Solution For Linux
by Peter Reutemann 23 Apr '15

23 Apr '15

"X2Go is an Open Source remote desktop application for GNU/Linux that uses NX technology protocol. The main difference between X2Go and other remote desktop applications is it provides secure standalone remote desktop sessions via SSH. So, each session connected using X2Go is strongly encrypted and safe. X2Go allows you mainly to connect to Linux systems from Linux, Windows, or Mac OS systems. Also, many clients can simultaneously connect and use single X2Go server. It comes with two components, namely X2Go server and X2Go client. X2Go server is a system that is being accessed from a client system. And, the X2Go is a system which can be used to access the X2Go server. This Client will be able to connect to X2Go server(s) and start, stop, resume and terminate (running) desktop sessions. X2Go Client stores different server connections and may automatically request authentication data from LDAP directories. Furthermore it can be used as fullscreen loginscreen (replacement for loginmanager like xdm)." -- source: http://www.unixmen.com/x2go-an-open-source-remote-desktop-solution-for-linu… Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174 http://www.data-mining.co.nz/

8 Linux file managers to try
by Peter Reutemann 23 Apr '15

23 Apr '15

"One of the most common administrative tasks that end users and administrators alike need to perform is file management. Managing files can consume a major portion of your time. Locating files, determining which files and folders (directories) are taking the most disk space, deleting files, moving files, and simply opening files for use in an application are some of the most basic—yet frequent—tasks we do as computer users. File management programs are tools that are intended to streamline and simplify those necessary chores." -- source: http://opensource.com/business/15/4/eight-linux-file-managers My gripes with Caja (MATE's equivalent of Nautilus) is that it cannot handle lots of files in a directory. A directory containing 10s of thousands of files will bring the file browser to a stand still for several minutes. Midnight commander takes less than a second for the same directory. Krusader is pretty good as well, with 1-2 seconds. Nice thing about Krusader: both panels can have multiple tabs, making it quite versatile.

Controversy Over KDBUS
by Lawrence D'Oliveiro 16 Apr '15

16 Apr '15

KDBUS is the in-kernel implementation of D-BUS, which is a core interprocess communication architecture used to build the GUI in every desktop Linux system today. Putting this code in the kernel provides performance improvements, as well as fixing many limitations that cannot be overcome by userspace-only code. After quite a few years of development, it looked like KDBUS was finally ready for merging into the Linux 4.1 kernel. However, controversy has now erupted. It seems from a look at few of the comments that they are objecting, not to the implementation, but to the protocol, which cannot be changed, otherwise it is no longer a drop-in replacement for D-BUS. <http://www.phoronix.com/scan.php?page=news_item&px=KDBUS-Taking-Heat>

The Document Liberation, one year after
by Lawrence D'Oliveiro 14 Apr '15

14 Apr '15

The Document Liberation is an offshoot of The Document Foundation (responsible for LibreOffice) to manage all the handling of proprietary/legacy document formats in a form that can be reused by other projects, not just LibreOffice. I like the name of the framework library they created: “librevenge”--the aim, of course, being to strike a blow against all the companies locking up users’ data in undocumented, proprietary formats which they then abandoned. For example, look at the support for Microsoft Works--anybody else even remember what that was? (Puts hand up.) It’s probably true to say that Open Source software now has better handling of many of these ancient formats than any current product from the companies that originally created those formats. <http://lwn.net/Articles/640198/>

Git This: World's Favorite Software Development Tool Turns 10
by Peter Reutemann 07 Apr '15

07 Apr '15

'Linux today is built faster than ever before. The latest data proves it. This is due to the distributed, global community of developers, IT managers and companies contributing to it every minute of every day. This massive collaboration is made possible with similarly distributed tools, tools like Git. Linus Torvalds 10 years ago today released Git after it was clear BitKeeper was no longer an option for the Linux community. He assessed other existing revision control systems and decided none would do. Ultimately, he decided he would just write a new one, so he went away for a weekend and came back with another hole in one. Most people know Linus created Linux, but many don’t know he is the mastermind behind what has become the most popular revision control system in software development today. If you ask him which is his crowning achievement, he’ll say “do I have to have just one?”' -- source: http://www.linux.com/news/featured-blogs/158-jim-zemlin/821847 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

VMware Being Sued For Infringing GPL
by Lawrence D'Oliveiro 28 Mar '15

28 Mar '15

As I understand it, an important part of VMware’s closed-source hypervisor depends on Linux device drivers to communicate with hardware. VMware implemented their own interface, compatible with the Linux one, in order to allow these drivers to work. However, in doing so, they appear to have copied a lot of GPL-licensed code from the actual Linux kernel. There are probably more subtleties to the lawsuit than that, but more details here: <http://lwn.net/Articles/635290/>.

RaspEX - another Linux version for Raspberry Pi
by Ian Young 25 Mar '15

25 Mar '15

That man from Sweden has now put together a Linux version for the Pi. He wants money for it however. $7 US. http://raspex.exton.se/ News 150318 I have made a perfect (as I think) Linux ARM system for Raspberry Pi 2. I call it RaspEX. It is based on Debian Jessie (upcoming Debian 8), Ubuntu Vivid Vervet (upcoming Ubuntu 15.04) and Linaro (Open Source software for ARM SoCs). Why shall I use RaspEX? Eight Operating Systems are recommended by Raspberry.org. Among them Noobs, Raspbian (Debian Wheezy) and Snappy Ubuntu Core. RaspEX is faster, more useful and more fun to use. (In my opinion). How do I install RaspEX? Just like any other Raspberry system. I.e.: Unpack the downloaded ZIP file (raspex-ubuntu-15.04-armhf-923mb-150318.zip) and transfer the IMAGE file (raspex-ubuntu-15.04-armhf-3050mb-150318.img) to your Micro SD card of at least 8GB. http://linux.softpedia.com/get/Linux-Distributions/RaspEX-103737.shtml

MIPS Wants To Join In The Fun
by Lawrence D'Oliveiro 24 Mar '15

24 Mar '15

With all the huge popularity of ARM chips in mobile and embedded devices, Imagination Technologies (owner of the MIPS architecture) would like to remind us that the MIPS ecosystem shipped 800 million chips last year, making them the world’s number 2 CPU architecture. This article <http://arstechnica.com/gadgets/2015/03/imagination-technologies-wants-to-ta…> reviews a reference tablet design running Firefox OS. Not impressive in itself, but hopefully a forerunner of things to come? And earlier they announced their CI20 development/hobbyist board <http://arstechnica.com/gadgets/2015/02/mips-creator-ci20-released-interesti…>, clearly trying to take on the BeagleBoard and Raspberry π market.

Someone on the internet said, "The advantage of Android is that you are free to tweak everything to your liking. The disadvantage is that you have to."

Seems picky about hardware, more so than the Kitkat from android-x86 project. Meanwhile the release of a new Apple lightweight laptop reveals the existence of USB-C.

You Thought PC Security Was Bad...
by Lawrence D'Oliveiro 06 Mar '15

06 Mar '15

To those still reeling from Baden’s presentation on cracking PC security, there’s worse to come. At least PC OSes do get some patching. But think of all the other devices around your home which have the core of a computer running something resembling an operating system on them which might be many years out of date (even on a newer device!). But the vendor can’t be bothered to provide fixes for any security holes which may be discovered. And even if they did, most of the buyers of these devices wouldn’t even know patches were available. Case in point: wireless routers, which are so full of unpatched holes that it’s actually unusual to find a reasonably secure one <http://www.theregister.co.uk/2015/03/05/broadband_routers_sohopeless_and_ve…>.

Red Hat Strips Down For Docker

"Reacting to the surging popularity of the Docker virtualization technology, Red Hat has customized a version of its Linux distribution to run Docker containers. The Red Hat Enterprise Linux 7 Atomic Host strips away all the utilities residing in the stock distribution of Red Hat Enterprise Linux (RHEL) that aren't needed to run Docker containers. Removing unneeded components saves on storage space, and reduces the time needed for updating and booting up.

Software Freedom Conservancy Funds GPL Suit Against VMWare

"Jeremy Allison - Sam writes with this excerpt from a news release from the Software Freedom Conservancy: Software Freedom Conservancy announces today Christoph Hellwig's lawsuit against VMware in the district court of Hamburg in Hamburg, Germany. This is the regretful but necessary next step in both Hellwig and Conservancy's ongoing effort to convince VMware to comply properly with the terms of the GPLv2, the license of Linux and many other Open Source and Free Software included in VMware's ESXi products. Serge Wroclawski points out the SFC's technical FAQ about the suit. One nugget: This case is specifically regarding a combined work that VMware allegedly created by combining their own code (“vmkernel”) with portions of Linux's code, which was licensed only under GPLv2. As such, this, to our knowledge, marks the first time an enforcement case is exclusively focused on this type of legal question relating to GPL" -- source: http://linux.slashdot.org/story/15/03/05/1721231 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

FREAK Attack Threatens SSL Clients
by Peter Reutemann 04 Mar '15

04 Mar '15

"For the nth time in the last couple of years, security experts are warning about a new Internet-scale vulnerability, this time in some popular SSL clients. The flaw allows an attacker to force clients to downgrade to weakened ciphers and break their supposedly encrypted communications through a man-in-the-middle attack. Researchers recently discovered that some SSL clients, including OpenSSL, will accept weak RSA keys–known as export-grade keys–without asking for those keys. Export-grade refers to 512-bit RSA keys, the key strength that was approved by the United States government for export overseas. This was an artifact from decades ago and it was thought that most servers and clients had long ago abandoned such weak ciphers. The vulnerability affects a variety of clients, most notably Apple's Safari browser." -- source: http://it.slashdot.org/story/15/03/03/2036241 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Linux and Multiple Internet Uplinks: a New Tool
by Peter Reutemann 04 Mar '15

04 Mar '15

"Linux has been able do multipath routing for a long time: it means being able to have routes with multiple gateways and to use them in a (weighted) round-robin fashion. But Linux is missing a tool to actively monitor the state of internet uplinks and change the routing accordingly. Without it, from a LAN perspective, it's like having a RAID-0: just one uplink goes down and all of your LAN-to-WAN traffic goes down too. Documentation and examples on the subject are lacking; existing solutions are few and deeply integrated in firewall/routing specific distributions. To address these issues, a new standalone tool was just released: Fault Tolerant Router. It also includes a complete (iptables + ip policy routing) configuration generator." -- source: http://linux.slashdot.org/story/15/03/03/1910206 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

A Tale Of Two Standards
by Lawrence D'Oliveiro 03 Mar '15

03 Mar '15

Came across this article from a decade ago <https://www.samba.org/samba/news/articles/low_point/tale_two_stds_os2.html> about the evolution of the POSIX and Win32 standards from the viewpoint of a veteran who earned his scars in the trenches. While POSIX got one or two things spectacularly wrong (e.g. the disaster that is file locking), it got a lot of things right (e.g. abstracting data types for file offsets/sizes, timestamps etc). Wonder why WINE has taken so long to get to where it is? It’s because nobody can be quite sure they have flushed out every last wrinkle of the behaviour of every Win32 API call.

Android-x86 -- the story continues
by Ian Young 24 Feb '15

24 Feb '15

Who knew? Android doesn't play nicely with a 2nd display. However investigation continues. Some say the internal display should be turned off, before the outside screen will go. Watch this space. Meanwhile some may like to read an interview with English as not the primary language featuring Chih-Wei Huang, main man of Android-x86. Snip > Why Android-x86? Runs on PC(x86). Original Android runs on ARM. Android - Teoreticaly could run on every present and future device, PS4 and Xbox one included (in pure theory). Is everytime better develop for only one OS (even with some platform differences), that for bunch of them. Mac OS or iOS are too closed and fixed on Apple device and its unlikely to change it. Linux market is realy fragmented and its development is relatively slow. Android - is without doubt OS with faster development speed and it counts. Android is open and free. Today, when i can buy good living room pc for 200$ i realy dont wan to pay next 100 bucks to Microsoft for crippled OEM licence, or 200$ for retail (HW independed licence) .... > How many of users know you think that tried Android-x86, at least through live distro and how many installed it into physical computer? Do you have some stats about usage? I don't have the stats and I don't really care about that. Just checked. The 4.4-RC1 release has 584,441 downloads and the 4.3-test release has 1,365,182 downloads. > Are you in contact with Google? Do you know why Google isn't developing Android-x86 for desktops itself? Is affair of Microsoft or something else? ChromeOS looks like duplicity. I have no official contact window of Google. But I have many friends in Google including the android team. I'll also contact Google android engineers directly for issues clarification or patches submission. I don't know Google's plan. But as you said, ChromeOS is probably the right one for its desktop roadmap. This is a common guess. < stop snipping http://www.gamasutra.com/blogs/RuthanielVandenNaar/20140612/219170/Current_…

Debian’s Reproducible Binary Project Reaches 83% Mark
by Lawrence D'Oliveiro 24 Feb '15

24 Feb '15

For a while now, Debian has been running a project to try to allow anyone to independently confirm that a particular Debian package was indeed built from a particular set of sources, by being able to reproduce the exact build steps themselves. (The security rationale for wanting to do so should be obvious.) As you can imagine, this is seriously non-trivial to achieve, since the least little difference in the version of your compilers or libraries can cause the binaries to differ, maybe not in any important way, but the idea is to end up with no differences at all. The Register has a report on the status of the project here <http://www.theregister.co.uk/2015/02/23/debian_project/>. More background here <https://lists.debian.org/debian-devel-announce/2015/02/msg00007.html>.

“SSL hijacker” behind Superfish debacle imperils large number of users
by Peter Reutemann 21 Feb '15

21 Feb '15

I know, this is not strictly Linux related, but scary nonetheless and worthy of sharing, IMHO: "Thursday's revelations that Lenovo PCs ship with adware that intercepts sensitive HTTPS-protected traffic have focused intense scrutiny on Superfish, the company that markets the intrusive software. But lost in the furor is the central role a company called Komodia plays in needlessly exposing the passwords and other sensitive data of not just Lenovo customers but also a much larger base of PC users." -- source: http://goo.gl/KhA4KT Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Empire of the Gates
by Ian Young 20 Feb '15

20 Feb '15

Better snap back to reality. On Arstechnica I see the following data as of 11/2014. OS share worldwide -- Windows allsorts 91.28%, OS X 7.27, all others [weeps] 1.45. Windows breakdown XP 13.57%, Vista 2.65, Win 7 56.41, Win 8 6.55, Win 8.1 12.1. http://arstechnica.com/gadgets/2015/01/you-can-offer-people-windows-10-for-… All hail his Billness. Though the figures for systems other than desktops must show a different story, and in phone and tablet world Windows is pretty well a joke apart from some misguided corporate purchases. (I stand to be corrected on that). Meanwhile back in the day, I had GEOS installed and it was passable. Even ran it within OS/2, freaky or what? Speaking of OS/2 last time I looked there were still some zealots keeping it working after a fashion. -quote- Unfortunately, OS/2 had a crucial flaw in its design: a Synchronous Input Queue (SIQ). What this meant was that all messages to the GUI window server went through a single tollbooth. If any OS/2 native GUI app ever stopped servicing its window messages, the entire GUI would get stuck and the system froze. OK, technically the operating system was still running. Background tasks continued to execute just fine. You just couldn’t see them or interact with them or do anything, because the entire GUI was hung. Some enterprising OS/2 fan wrote an application that polled the joystick port and was supposed to unstick things when the user pressed a button. It rarely worked. Ironically, if you never ran native OS/2 applications and just ran DOS and Windows apps in a VM, the operating system was much more stable. -quote- http://arstechnica.com/business/2013/11/half-an-operating-system-the-triump… And now we return to our normal programme and wonder whether Linux v4 is soon to arrive. 19 million lines in the kernel and counting. http://linuxgizmos.com/is-linux-heading-toward-the-big-4-0/

Microsoft's First Azure Hosted Service Is Powered By Linux

"Canonical, through John Zannos, VP Cloud Alliances, has proudly announced that the first ever Microsoft Azure hosted service will be powered by Ubuntu Linux. This piece of news comes from the Strata + Hadoop World Conference, which takes place this week in California. The fact of the matter is that the news came from Microsoft who announced the preview of Azure HDInsight (an Apache Hadoop-based hosted service) on Ubuntu clusters yesterday at the said event. This is definitely great news for Canonical, as their operating system is getting recognized for being extremely reliable when handling Big Data.

Arduino Ructions
by Lawrence D'Oliveiro 19 Feb '15

Seems like the Arduino founders have split to go their separate ways <https://www.techdirt.com/articles/20150217/10345530055/is-arduino-heading-t…>. The unfortunate thing is that there are now lawsuits to try to decide who has exclusive rights to the “Arduino” name. Whatever happens, it seems likely there will continue to be more than one company making products that are “Arduino” in every way, if not in name. This is nothing new in open-source software, though it may be a first for open-source hardware.

How to rool the world by Bill G
by Ian Young 19 Feb '15

19 Feb '15

Become the main supplier of an OS for PCs while IBM snoozes, replete with profits from existing business. Adopt the 386 processor while IBM messes about with the 286 perhaps because of sunk investment in that CPU. Make deals with the hardware makers they can't refuse and shut out any competition. Introduce the first GUI to become widely used on the machines soon to become predominant in desktop computing. Leave the superior OS/2 in the dust, and get IBM to sell Windows. Excel. Actually first came to fame on the Mac iirc, and rapidly drove out just about all other spreadsheets in its Windows guise. On its coattails came all the other applications we know today as MS Office, effectively wiping out all competitors. Get networking in the box with Windows and crush Netware and eventually Novell with it. And so it went until perhaps MS became like IBM in the 1980s and failed to see the next big thing on several occasions, or at least failed to achieve the same level of dominance as in the past in new fields. 2 cents is the suggested donation, I'll pass the hat around.

I think its people with a technical interest that use Linux on the desktop, either because they are familiar with it on servers, are passionate about the 'freeness' of it or the ease (including cost) with which they can set up a development environment. I think the big players like Apple and Microsoft would have to make some serious stuff-ups for the rest of population to go through the hassle of switching OSes on their current desktops. While many of the FOSS applications (GIMP/LibreOffice/Firefox) run just fine on Windows (and possible Mac too I don't know), they also reduce the imperative to shift entirely to Linux or BSD. And the only thing I see that really could shift the corporate environment is a server based Office(Document/Spreadsheet/Mail) solution that was so compelling, that eventually system administrators started to wonder if there was any point in sticking exclusively to an MS Desktop. Cloud computing, Smart TVs and the advent of Android and iPhone have certainly helped computer *users* become more comfortable with alternative OS and user interfaces. -- Chris

FreeBSD-Current Random Number Generator Broken

Google Chrome Will Adopt HTTP/2 In the Coming Weeks, Drop SPDY Support

PC-BSD - ubiquitous in world of future - or not
by Ian Young 18 Feb '15

18 Feb '15

Some years ago I had a brief dabble with PC-BSD. It was brief because every time I attempted to boot a live DVD the system would fail to boot or run only for a few minutes before crashing. The same equipment had no trouble with various Linux distros. That was then of course and the project continues to exist so presumably some people have managed to run it. However I will stick my neck out and say that imho PC-BSD is a most unlikely candidate for world domination .... Any one seen it in action? I think when I tried it there were issues like limited support for USB, and driver support still lags behind Linux.

PC-BSD: Set For Serious Growth?
by Peter Reutemann 17 Feb '15

'Luke Wolf, a KDE developer, argues that PC-BSD might become a serious desktop OS contender by year 2020, since Linux so far has failed to grasp any serious market share. He writes, "Consider this: In the past 10 years has the distribution you run changed significantly in what it offers over other distributions? I think you'll find the answer is largely no. I do have to give a shout out to openSUSE for the OBS, but otherwise I've used my desktop in the same exact way that I have always used it within the continuity of distribution X,Y, or Z since I started using them. Distributions simply aren't focused on desktop features, they're leaving it up to the DEs to do so." He continues, "PC-BSD on the other hand in fitting with the BSD mindset of holistic solutions is focused on developing desktop features and is moving rapidly to implement them." What do you think?' -- source: http://bsd.slashdot.org/story/15/02/16/2355236 NB: Mentioning "Linux + Year of the Desktop" is always bait for a flamewar. But...

Removing Libsystemd0 From a Live-running Debian System
by Peter Reutemann 16 Feb '15

16 Feb '15

"The introduction of systemd has unilaterally created a polarization of the GNU/Linux community that is remarkably similar to the monopolistic power position wielded by Microsoft in the late 1990s. Choices were stark: use Windows (with SMB/CIFS Services), or use UNIX (with NFS and NIS). Only the introduction of fully-compatible reverse-engineered NT Domains services corrected the situation. Instructions on how to remove systemd include dire warnings that "all dependent packages will be removed", rendering a normal Debian Desktop system flat-out impossible to achieve. It was therefore necessary to demonstrate that it is actually possible to run a Debian Desktop GUI system (albeit an unusual one: fvwm) with libsystemd0 removed. The reason for doing so: it doesn't matter how good systemd is believed to be or in fact actually is: the reason for removing it is, apart from the alarm at how extensive systemd is becoming (including interfering with firewall rules), it's the way that it's been introduced in a blatantly cavalier fashion as a polarized all-or-nothing option, forcing people to consider abandoning the GNU/Linux of their choice and to seriously consider using FreeBSD or any other distro that properly respects the Software Freedom principle of the right to choose what software to run. We aren't all "good at coding", or paid to work on Software Libre: that means that those people who are need to be much more responsible, and to start — finally — to listen to what people are saying. Developing a thick skin is a good way to abdicate responsibility and, as a result, place people into untenable positions." -- source: http://news.slashdot.org/story/15/02/15/1959209 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Live Patching Now Available For Linux
by Peter Reutemann 13 Feb '15

13 Feb '15

'It provides a basic infrastructure for function "live patching" (i.e. code redirection), including API for kernel modules containing the actual patches, and API/ABI for userspace to be able to operate on the patches (look up what patches are applied, enable/disable them, etc). It's relatively simple and minimalistic, as it's making use of existing kernel infrastructure (namely ftrace) as much as possible. It's also self-contained, in a sense that it doesn't hook itself in any other kernel subsystem (it doesn't even touch any other code). It's now implemented for x86 only as a reference architecture, but support for powerpc, s390 and arm is already in the works (adding arch-specific support basically boils down to teaching ftrace about regs-saving).' -- source: http://linux.slashdot.org/story/15/02/12/1853215 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Firefox To Mandate Extension Signing
by Peter Reutemann 12 Feb '15

12 Feb '15

'In a recent blog post, Mozilla announced its intention to require extensions to be signed in Firefox, without any possible user override. From the post: "For developers hosting their add-ons on AMO, this means that they will have to either test on Developer Edition, Nightly, or one of the unbranded builds. The rest of the submission and review process will remain unchanged, except that extensions will be automatically signed once they pass review. For other developers, this is a larger change. For testing development versions, they’ll have the same options available as AMO add-on developers. For release versions, however, we’re introducing the required step of uploading the extension file to AMO for signing. For most cases, this step will be automatic, but in cases where the extension doesn’t pass these tests, there will be the option to request a manual code review."' -- source: http://tech.slashdot.org/story/15/02/11/210247 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Users and groups are not really determinitive for permissions, now that we have things like polkit running around. (Yes, by the way, I am a member of plugdev.) Error messages are unhelpful (WHY was I not authorized?) and logs are nowhere to be found. Traditionally, one could twiddle who could mount devices via /etc/fstab lines and perhaps some sudo rules. Granted, you had to know where to look, but when you did, it was simple; only two pieces to fit together.

Elementary OS: Why We Make You Type "$0"
by Peter Reutemann 11 Feb '15

11 Feb '15

'Open source software can always be acquired without charge, but can still incur significant development costs. Elementary OS wants to make people aware of this, and have changed their website to suggest donating when downloading, and make users explicitly enter "$0" if they want a free download. This is the same strategy Canonical has used when offering Ubuntu. The Elementary OS blog explains: "Developing software has a huge cost. Some companies offset that cost by charging hundreds of dollars for their software, making manufacturers pay them to license the software, or selling expensive hardware with the OS included. Others offset it by mining user data and charging companies to target ads to their users. [...] If we want to see the world of open source software grow, we should encourage users to pay for its development; otherwise it'll be underfunded or developers will have to resort to backdoor deals and advertising. And nobody wants that future." Currently the only people who have received money for working on Elementary OS have been community members through their bounty program.' -- source: http://news.slashdot.org/story/15/02/11/1753219 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

New Multi-Purpose Backdoor Targets Linux Servers
by Peter Reutemann 09 Feb '15

09 Feb '15

'A new multi-purpose Linux Trojan that opens a backdoor on the target machine and can make it participate in DDoS attacks has been discovered and analyzed by Dr. Web researchers, who believe that the Chinese hacker group ChinaZ might be behind it. "First, Linux.BackDoor.Xnote.1 sends information about the infected system to the server. It then goes into standby mode and awaits further instructions. If the command involves carrying out some task, the backdoor creates a separate process that establishes its own connection to the server through which it gets all the necessary configuration data and sends the results of the executed task," the researchers explained.' -- source: http://linux.slashdot.org/story/15/02/09/1829255 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Xfce Getting a New Version Soon
by Peter Reutemann 08 Feb '15

08 Feb '15

'It looks like the release of Xfce 4.12 is finally about to materialize. It has been about two and half years since the last stable release. There is now a concerted effort underway to ship a new release of this lightweight GTK+2 desktop environment out around the end of February or early March. "As we have discussed the status and progress of core components with many of you individually, we feel confident that the state of Xfce is good enough to polish some final edges and push more translations until then," wrote Simon Steinbeiß on the xfce4-dev mailing list. The official list of showstopper bugs does not look too bad either. However, looking at the long time between releases certainly makes one think if the project could have use for some extra resources.' -- source: http://tech.slashdot.org/story/15/02/08/1431250 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

The First Ubuntu Phone Is Here, With Underwhelming Hardware
by Peter Reutemann 08 Feb '15

08 Feb '15

'A few days ago, Fast Company reviewer Jay Cassano was enthusiastic about Ubuntu's approach to apps for its new phone OS: namely, not relying on them, and instead interfacing seamlessly with existing websites and protocols. Now, new submitter ablutions (4006541) writes with a less than glowing review at The Daily Dot of the actual hardware that the OS is launching on. A sample that conveys the gist: "Let's start with the good stuff: It sports a 4.5-inch multi-touch screen and a respectable 8-megapixel rear camera and 5-megapixel lens on the front. That's pretty much it. The list of negatives is a bit longer."' -- source: http://tech.slashdot.org/story/15/02/08/0034236 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

The Ubuntu handset can run apps written in either the HTML5 web programming language or its own native QML code. However, its operating system effectively hides them away. Instead of the traditional smartphone user interface - featuring grids of apps - it uses themed cards that group together different facilities. --unsnip-- Chocolate fish for first person to bring one to a meeting?

Samba issues
by David Nicholls 04 Feb '15

04 Feb '15

Hi guys. I am having an issue with my fresh samba setup. I built a 14.04.1 LTS Ubuntu server and set up a single mount point (/media/data) and pointed 3 separate internal hard drives to it (eg it contains directories "music_drive", "tv_drive" & "movie_drive"). I turned "/media/data" into a samba share. Annoyingly permissions look fine but I cannot seem to be able to either see the share on my network from other machines or connect to it. Even using the servers IP address. Any advice? Or am I just missing something obvious. My config is below. samba.conf # # Sample configuration file for the Samba suite for Debian GNU/Linux. # # # This is the main Samba configuration file.

Hi there Just playing around with Android tethering / wifi hotspot on my phone. One question that I have is, how do I fix the IP address that my phone assigns to a client when acting as an access point? Is there an App that I can use to tie a client's Mac ID to certain IP address, like you can usually do with "regular" wireless access points? Thanks.

OpenSSH Will Feature Key Discovery and Rotation For Easier Switching To Ed25519
by Peter Reutemann 01 Feb '15

01 Feb '15

"OpenSSH developer Damien Miller has posted about a new feature he implemented and committed for the next upcoming 6.8 release of OpenSSH — hostkeys(a)openssh.com — an OpenSSH extension to the SSH protocol for sshd to automatically send all of its public keys to the client, and for the client to automatically replace all keys of such server within ~/.ssh/known_hosts with the fresh copies as supplied (provided the server is trusted in the first place, of course). The protocol extension is simple enough, and is aimed to make it easier to switch over from DSA to the OpenSSL-free Ed25519 public keys. It is also designed in such a way as to support the concept of spare host keys being stored offline, which could then seamlessly replace main active keys should they ever become compromised." -- source: http://it.slashdot.org/story/15/02/01/0533208 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Dell Continues Shipping Fresh Linux Laptops

"In its latest move, Dell will be bringing Ubuntu 14.04 LTS to its top-of-the-line Precision M3800 workstation laptop and the latest model of the Dell XPS 13. Both systems will be running Ubuntu 14.04.1. According to Barton George, Dell's Director of Developer Programs, programmers had been asking for a better, officially-supported Ubuntu developer laptop. This came about from a combination of the efforts of Dell software engineer Jared Dominguez and enthusiastic feedback. Specs of M3800: 15.6" LCD @ 3840x2160, Intel i7 quad core CPU, NVIDIA Quadro GPU, up to 16 GB RAM. The bad news is, as Dominguez explained on his blog, this version of the M3800 doesn't support its built-in Thunderbolt 2 port out of the box. However, thanks to the hardware-enablement stack in Ubuntu, starting with upcoming Ubuntu 14.04.2, you will be able to upgrade your kernel to add some Thunderbolt support." -- source: http://linux.slashdot.org/story/15/01/31/180203 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

FSF-Endorsed Libreboot X200 Laptop Comes With Intel's AMT Removed

The laptop ships with 100% free software and firmware, including the FSF's endorsed Trisquel GNU/Linux and Libreboot. One of the biggest challenges overcome in achieving FSF's Respects Your Freedom certification was the complete removal of Intel's ME and AMT firmware. The AMT is a controversial proprietary backdoor technology that allows remote access to a machine even when it is powered off. Quoting from the press release: "The ME and its extension, AMT, are serious security issues on modern Intel hardware and one of the main obstacles preventing most Intel based systems from being liberated by users. On most systems, it is extremely difficult to remove, and nearly impossible to replace. Libreboot X200 is the first system where it has actually been removed, permanently," said Gluglug Founder and CEO, Francis Rowe."' -- source: http://hardware.slashdot.org/story/15/01/29/2241214 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Mozilla Dusts Off Old Servers, Lights Up Tor Relays
by Peter Reutemann 29 Jan '15

"According to The Register, "Mozilla has given the Tor network a capacity kick with the launch of 14 relays that will help distribute user traffic. Engineers working under the Foundation's Polaris Project inked in November pulled Mozilla's spare and decommissioned hardware out of the cupboard for dedicated use in the Tor network. It included a pair of Juniper EX4200 switches and three HP SL170zG6 (48GB ram, 2*Xeon L5640, 2*1Gbps NIC) servers, along with a dedicated existing IP transit provider (2 X 10Gbps). French Mozilla engineer Arzhel Younsi (@xionoxfr) said its network was designed to fall no lower than half of its network capacity in the event of maintenance or failure. The Polaris initiative was a effort of Mozilla, the Tor Project and the Centre for Democracy and Technology to help build more privacy controls into technology." -- source: http://hardware.slashdot.org/story/15/01/29/192215 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Serious Network Function Vulnerability Found In Glibc
by Peter Reutemann 28 Jan '15

28 Jan '15

"A very serious security problem has been found and patched in the GNU C Library (Glibc). A heap-based buffer overflow was found in __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() function calls. A remote attacker able to make an application call to either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the program. The vulnerability is easy to trigger as gethostbyname() can be called remotely for applications that do any kind of DNS resolving within the code. Qualys, who discovered the vulnerability (nicknamed "Ghost") during a code audit, wrote a mailing list entry with more details, including in-depth analysis and exploit vectors." -- sources: http://news.slashdot.org/story/15/01/27/1925208 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Opera Founder Is Back, WIth a Feature-Heavy, Chromium-Based Browser
by Peter Reutemann 27 Jan '15

27 Jan '15

"Almost two years ago, the Norwegian browser firm Opera ripped out the guts of its product and adopted the more standard WebKit and Chromium technologies, essentially making it more like rivals Chrome and Safari. But it wasn't just Opera's innards that changed; the browser also became more streamlined and perhaps less geeky. Many Opera fans were deeply displeased at the loss of what they saw as key differentiating functionality. So now Jon von Tetzchner, the man who founded Opera and who would probably never have allowed those drastic feature changes, is back to serve this hard core with a new browser called Vivaldi." -- source: http://tech.slashdot.org/story/15/01/27/1733259 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

EFF Unveils Plan For Ending Mass Surveillance
by Peter Reutemann 27 Jan '15

27 Jan '15

'The Electronic Frontier Foundation has published a detailed, global strategy for ridding ourselves of mass surveillance. They stress that this must be an international effort — while citizens of many countries can vote against politicians who support surveillance, there are also many countries where the citizens have to resort to other methods. The central part of the EFF's plan is: encryption, encryption, encryption. They say we need to build new secure communications tools, pressure existing tech companies to make their products secure against everyone, and get ordinary internet-goers to recognize that encryption is a fundamental part of communication in the surveillance age. They also advocate fighting for transparency and against overreach on a national level. "[T]he more people worldwide understand the threat and the more they understand how to protect themselves—and just as importantly, what they should expect in the way of support from companies and governments—the more we can agitate for the changes we need online to fend off the dragnet collection of data." The EFF references a document created to apply the principles of human rights to communications surveillance, which they say are "our way of making sure that the global norm for human rights in the context of communication surveillance isn't the warped viewpoint of NSA and its four closest allies, but that of 50 years of human rights standards showing mass surveillance to be unnecessary and disproportionate."' -- source: http://yro.slashdot.org/story/15/01/27/042212 Cheers, Pete -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

'There has been quite a debate around the Linux version of The Witcher 2: Assassins of Kings and the fact that it wasn't really a port. A special kind of wrapper was used to make the Windows version of the game run on Linux systems, similar to Wine. The performance on Linux systems took a hit and users felt betrayed because they thought that they would get a native port. However, after the gamestopped launching properly at some point, the reason was actually found to be a Linux regression.Linus quickly took care of the issue on an unofficial Witcher 2 issue tracker on GitHub: "It looks like LDT_empty is buggy on 64-bit kernels. I suspect that the behavior was inconsistent before the tightening change and that it's now broken as a result. I'll write a patch. Serves me right for not digging all the way down the mess of macros." This one goes to the bin "don't break userspace". Linus also reminds of QA: "And maybe this is an excuse for somebody in the x86 maintainer team to try a few games on steam. They *are* likely good tests of odd behavior.."' -- source: http://games.slashdot.org/story/15/01/24/1528232 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Accidentally Deleting Directories
by Lawrence D'Oliveiro 21 Jan '15

21 Jan '15

I suppose every seasoned Linux user has been there (I know I have): done “rm -rf” (or equivalent) to wipe out a directory, only to realize--too late--that it was the wrong one. There’s a discussion currently raging <http://www.theregister.co.uk/2015/01/17/scary_code_of_the_week_steam_cleans…> over a bug just like this in the Steam client for Linux. There is a script that contains the line rm -rf "$STEAMROOT/"* However, as a result of certain (unusual) user actions, the value of the STEAMROOT variable could end up empty, in which case the script proceeds to wipe out every file on the system that your userid has privilege over. What’s the best way to handle this? On the one hand, when setting up a new installation/preferences directory, you want to ensure there is no leftover rubbish in it. But on the other, you want to ensure that any existing directory you delete/replace is in fact an old installation/preferences directory. I’m leaning towards the solution--discussed in the GitHub issue entry--of checking for some distinctive file in the existing directory. If that doesn’t exist, then the directory is not what the script thinks it is. For example, my wipetree script <https://github.com/ldo/git-useful/blob/master/wipetree> checks that there is a .git subdirectory in the directory you want to wipe. It also helps to use “set -e”, so bash aborts the script on an error, instead of barrelling on.

Canonical Launches Internet-of-Things Version of Ubuntu Core
by Peter Reutemann 21 Jan '15

21 Jan '15

'Ubuntu Linux isn't just for desktops, servers and the cloud anymore. Mark Shuttleworth wants Ubuntu to be the operating system of choice for the Internet of Things too. The new Snappy Ubuntu Core is targeted at device developers and it's the basis for an entire new division of Canonical Inc. The promise of Snappy Ubuntu Core is also one of security, protecting the devices of the world, by keeping them updated. "With Snappy there is also a division of responsibilities for updating that can also help protect IoT devices and users. So we could deliver an update for a Heartbleed or Shellshock vulnerability, completely independently of the lawnmower control app that would come from the lawnmower company," Shuttleworth said.' -- source: http://news.slashdot.org/story/15/01/20/2347214 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

The current state of video editing for Linux
by Peter Reutemann 21 Jan '15

21 Jan '15

"I often ask myself what the current state of video editing is for free and open source software (FOSS). Here are my thoughts. I've spent many years in the visual effects (VFX) industry from the perspective of being either an artist, compositor, video editor, or systems engineer. (I've even got film creds on IMDB!) In the past, I had the pleasure of cutting on, training people on, setting up, and supporting Avid Media Composer, the cream of the crop of professional real-time video editing tools for film and TV alike—at least before things like Final Cut Pro and Adobe Premiere became useful enough to professionals."

Hi everyone I've talked to the Bernhard Pfahringer, head of the computer science department, and he's willing to sponsor our meetings (WLUG and Python) again this year. Therefore, I booked the following dates for WLUG: Feb 23 Mar 23 Apr 27 May 25 Jul 27 Aug 24 Sep 28 Nov 23 NB: Some months are unavailable due to exam periods (these periods start already during study week, when the rooms get prepared and cannot be disturbed anymore). This brings me also to the next question: who's up for presenting at the first meeting in February? Any new, funky distros that anyone has taken for a spin? Any Linux-related projects tackled during the summer break? Feel free to contact me off-list and I'll add you to the meeting on meetup.com. As a reminder, our meetings get scheduled here: http://www.meetup.com/WaikatoLinuxUsersGroup/ Thanks and see you in February. Hope you all had a good summer break (at the least the folks in the southern hemisphere)!

Security Products Are Wasting Our Time
by Lawrence D'Oliveiro 18 Jan '15

18 Jan '15

Apparently 4 out of 5 alerts reported by malware-detection products are false alarms <http://arstechnica.com/security/2015/01/survey-says-security-products-waste…>. And of course the result is predictable: In 2013, for example, when cybercriminals broke into Target’s systems and loaded malware, the company’s FireEye security system issued an alert for the activity, but the company ignored the alerts. As a result, a District Court judge in Minnesota has given the go-ahead for banks to sue the retailer.

How Many Weeks Has “The Spectator” Been Publishing?
by Lawrence D'Oliveiro 16 Jan '15

16 Jan '15

Any other readers of “New Scientist” on this list? In the issue of 3rd Jan, the “Feedback” column tried to work out how many weeks various magazines that are still in existence had been publishing. The oldest they could find was “The Spectator”, which first came out on 6th July 1828. Unfortunately they were using Microsoft Excel to do their calculations, with predictably nonsensical results. :) Here’s what I came up with, using the good old “date” command, together with the arithmetic facilities built into bash. Taking it step by step: date +%s prints out the number of seconds since midnight 1st January 1970 to the present time. date -d "6-Jul-1828" +%s does the same for 6th July 1828. Of course this is a very small negative number. It computes and displays fine on my 64-bit system, but might overflow on 32-bit ones. echo $(($(date +%s) - $(date -d "6-Jul-1828" +%s))) prints out the subtraction of the above two numbers, giving the number of seconds from the founding of “The Spectator” to the present time. And finally, echo $(($(($(date +%s) - $(date -d "6-Jul-1828" +%s))) / $((86400 * 7)))) divides that number of seconds by the number of seconds in a week, giving the number of weeks from the founding of “The Spectator” to the present time. Which, by my reckoning, is 9732.

Fun With Fontconfig
by Lawrence D'Oliveiro 15 Jan '15

15 Jan '15

Fontconfig <http://www.freedesktop.org/wiki/Software/fontconfig/> is a set of command-line utilities, as well as an API for programs to use. It allows matching of fonts by names and other characteristics, rather than having to hard-code paths to font file names, or having to embed fonts into every document. For example, you format some text in a LibreOffice document. In the GUI, you will see a popup menu of all the fonts available on your system. Having chosen a font to use and saved your document, you send a copy to a friend. But they don’t have the same font installed, so LibreOffice uses Fontconfig to find the next best available font. As another example, Web pages commonly specify fonts by names like “serif” or even “Arial” (actually the name of a Microsoft-created clone of the original “Helvetica” font). While those who really care about typography and layout will use CSS font specifications to get the exact font they want from some server, the rest of us will muddle through with the common names, and expect the Web browser to find a suitable match on the user’s local machine. The command-line utilities allow you to observe this process in action. Given a reasonably vague font name, the fc-match command will show you the exact font file that will be chosen; thus, on my system: ldo(a)theon:~> fc-match -f "%{file}\n" arial /usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf (You will likely get a different result, depending on what fonts you have installed.) Sometimes the file names are not so explanatory: ldo(a)theon:~> fc-match -f "%{file}\n" palatino /usr/share/fonts/type1/gsfonts/p052003l.pfb in which case, the fc-query command will give you more info about what exactly is in that font file: ldo(a)theon:~> fc-query -f "%{family}\n" /usr/share/fonts/type1/gsfonts/p052003l.pfb URW Palladio L Or, you could have combined both steps into one: ldo(a)theon:~> fc-match -f "%{family} %{file}\n" palatino URW Palladio L /usr/share/fonts/type1/gsfonts/p052003l.pfb The list of what information item names you can put in those “%{...}” format specifiers is not mentioned in any of the man pages, but you can look in /usr/include/fontconfig/fontconfig.h, which is part of the libfontconfig1-dev package. Be warned, though: not all the items listed there will work with all fonts.

SystemD Gains New Networking Features
by Peter Reutemann 15 Jan '15

15 Jan '15

"A lot of development work is happening on systemd with just the recent couple of weeks seeing over 200 commits. With the most recent work that has landed, the networkd component has been improved with new features. Among the additions are IP forwarding and masquerading support (patch). This is the minimal support needed and these settings get turned on by default for container network interfaces. Also added was minimal firewall manipulation helpers for systemd's networkd. The firewall manipulation helpers (patch) are used for establishing NAT rules. This support in systemd is provided by libiptc, the library used for communicating with the Linux kernel's Netfilter and changing iptables firewall rulesets. Those wishing to follow systemd development on a daily basis and see what is actually happening under the hood, can keep tabs via the systemd Git viewer." -- source: http://linux.slashdot.org/story/15/01/14/2030259 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

What Does Using A Supercomputer Look Like?
by Lawrence D'Oliveiro 14 Jan '15

14 Jan '15

This article <http://www.theinquirer.net/inquirer/feature/1649635/sgi-advances-linux-hpc> is from a few years ago now, but it stuck in my mind about how running Linux on a proper supercomputer is little different from how it works on your own PC. Standard commands like “lspci” and “more /proc/cpuinfo” work exactly the same, except their output does go on a bit longer when your machine has 4096 cores, and peripheral attachments to match. And all done with a stock-standard Linux kernel: Goh was keen to mention that whatever SGI does to the Linux kernel, it does after making sure that any changes it makes will be accepted by the Linux kernel maintainers. Apparently getting the number of cores limit increased to 4,096 was something that he and his colleagues had to personally convince Linux founder Linus Torvalds to accept. According to Goh, convincing Torvalds was "tougher than designing the hardware".

Wireless Keylogger Masquerades as USB Phone Charger

"I have been developing some applications to use in small businesses using Windows and SQL Server. I would like to move on and start doing the same thing in Linux.

I use VS and C# mostly, although I could easily go back to C++. I found Qt and GTK+ are the most common frameworks, but they seem to lack controls that deal with datasets and stuff (sorry, spoiled by the .net form controls), but I also know that I could use Mono in order to make the jump. I would have no problem on moving to MySQL, as I have done quite a lot of work on that side, and I would like to stick with the traditional client server application, as I find it easier to maintain, and a whole lot more robust when it comes to user interaction (web apps for POS applications don't seem to be the right way to go in my view).

The 4 Best New Linux Distributions to Watch in 2015
by Peter Reutemann 12 Jan '15

12 Jan '15

"There was a time when new Linux distributions popped up on what seemed like a daily basis. They came and went so fast, you might have completely missed their short lives. That’s not so much the case these days. Linux distributions arrive a bit less frequently and, when they do finally arrive, tend to have a bit more staying power. Why is that? My guess would be that the stable of standard distributions has become so strong, it’s hard for competition to stand up to the likes of Ubuntu, Arch, Mint, Fedora, SUSE, and Debian. That doesn’t mean, however, that new distributions don’t try to take down the mighty standard bearers. In fact, there are a few distributions that could give those kings and queens of Linux a run for their money this year. Which ones, you ask? Let’s take a look at what I believe will be the distributions to watch in 2015." 1. Evolve OS 2. SparkyLinux GameOver Edition 3. Korora 4.

Would You Rent Out Your Unused Drive Space?

The removal of central controls would eliminate most traditional data failures and outages, as well as significantly increasing security, privacy, and data control.

Sloppy File Permissions Make Red Star OS Vulnerable
by Peter Reutemann 11 Jan '15

11 Jan '15

"Red Star OS Desktop 3.0, the official Linux distro of North Korea, which recently found its way onto torrents and various download sites in form of an ISO image, is interesting for a number of reasons, including its attempt to look like commercial operating systems (currently OS X, earlier versions mimicked the Windows GUI). Hackers are also poking Red Star for security vulnerabilities. An pseudonymous researcher noted in a post to the Open Source Software Security (oss-sec) mailing list, that the OS has one significant security hole: Red Star 3.0 ships with a world-writeable udev rule file /etc/udev/rules.d/85-hplj10xx.rules (originally designed for HP LaserJet 1000 series printers) which can be modified to include RUN+= arguments executing arbitrary commands as root by Udev.

There are 4 quite separate parts to these specs: * the USB 3.1 spec, supporting theoretical data rates up to 10Gb/s * the USB Power Delivery spec, which can supply up to 100W to connected devices * the new “Type C” connector, which has 4 separate physical data channels on it, including one for backward compatibility with USB 2.0 * USB Alternate Mode, which can use some or all of the Type C channels to communicate non-USB data (e.g. DisplayPort). In principle, it is neat to be able to replace all the different kinds of ports on a machine with ports all of a single kind. However, the article suggests that Alternate Mode could be a problem: it seems inevitable that different ports on a machine will be restricted to different uses for the Alternate Mode function. Which means, instead of the current situation where a monitor connector is different from a USB connector so you cannot plug a cable for one into the other, you will have the situation where all the connectors and cables _are_ the same, but if you plug the wrong device into the wrong port, it just won’t work. I remember in an e-mail exchange with Stuart Cheshire a few years ago (he was the mastermind behind the Zeroconf initiative, which Apple implemented as “Rendezvous”—later renamed “Bonjour”—and Linux users know as the “Avahi” packages), he said that there should indeed be just a single type of port on a computer, all speaking the same protocol. And that protocol should be TCP/IP. After all, why shouldn’t you run full TCP/IP between your keyboard, mouse and PC? The silicon it takes to implement the network stack shouldn’t amount to much of a cost these days. Of course, it should be IPv6, not IPv4...

Got an Asus router? Someone on your network can probably hack it
by Peter Reutemann 09 Jan '15

09 Jan '15

'If you're running an Asus wireless router, chances are good that someone inside your network can take full administrative control of it thanks to a currently unpatched vulnerability in virtually all versions of the firmware, a security researcher said. While the vulnerability isn't as serious as those that allowhackers on the Internet at large to compromise the devices, it's nonetheless concerning. People with administrative control can reroute everyone connected to malicious websites and possibly install alternate or even malicious firmware updates. "I trust people that join my network to some degree, but I don't want them to be able to reconfigure the router," Joshua Drake, research director at Accuvant and the person whobrought the vulnerability to light Thursday, told Ars. "I can't prevent them without this getting fixed (short of the workaround)."' -- source: http://arstechnica.com/security/2015/01/got-an-asus-router-someone-on-your-… Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

meetings
by Peter Reutemann 08 Jan '15

08 Jan '15

Hi everyone We're currently in the process of sorting out the dates for the monthly meetings this year. Ian S. suggested to not bother moving the meeting forward by a week if it falls on a Monday that is a public holiday, as we've done in the past. Why this change? The advantage would be that there is no confusion over *when* the meeting happens, it's always the 4th Monday. However, the downside could be that people are away or have no public transport to get to the meeting. What are your thoughts?

Extra Leap Second To Be Added To Clocks On June 30
by Peter Reutemann 08 Jan '15

08 Jan '15

"On June 30 this year, the day will last a tad longer — one second longer, to be precise — as a leap second is to be added to clocks worldwide. The time UTC will go from 23:59:59 to 23:59:60 in order to cope with Earth's rotation slowing down a bit. So, what do you intend to do during that extra second added to that day? Well, you may want to fix your systems. The last time a leap second was added, in 2012, a number of websites, Java and even Linux experienced some troubles. Leap seconds can be disruptive to precision systems used for navigation and communication. Is there a better way of dealing with the need for leap seconds?" -- source: http://news.slashdot.org/story/15/01/06/1821234 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

ODFPY Now Supports Python 3
by Lawrence D'Oliveiro 07 Jan '15

07 Jan '15

ODFPY is a very handy set of tools for manipulating Open Document Format files. Besides its own command-line tools, it also offers a Python class library that you can call from your own programs. I have been using this in my own billing system for many years to generate invoices for clients. This used to kept in a SVN repo on a somewhat slow server at <https://joinup.ec.europa.eu/software/odfpy/home>. But now they have moved to GitHub at <https://github.com/eea/odfpy>, and I see the current library works with Python 3 as well. This pleases me no end, as I have been moving many of my older projects across from Python 2.

Tips For Securing Your Secure Shell
by Peter Reutemann 07 Jan '15

07 Jan '15

"As you may have heard, the NSA has had some success in cracking Secure Shell (SSH) connections. To respond to these risks, a guide written by Stribika tries to help you make your shell as robust as possible. The two main concepts are to make the crypto harder and make stealing keys impossible. So prepare a cup of coffee and read the tutorial carefully to see what could be improved in your configuration. Stribika gives also some extra security tips: don't install what you don't need (as any code line can introduce a bug), use the kind of open source code that has actually been reviewed, keep your software up to date, and use exploit mitigation technologies." -- source: http://it.slashdot.org/story/15/01/07/161227 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Browsing in privacy mode? Super Cookies can track you anyway
by Peter Reutemann 07 Jan '15

"For years, Chrome, Firefox, and virtually all other browsers have offered a setting that doesn't save or refer to website cookies, browsing history, or temporary files.

I Just Want The Root Filesystem!
by Lawrence D'Oliveiro 06 Jan '15

06 Jan '15

Sometimes you want to perform some operation on the volume mounted at /, but not in any volume mounted under it. Some commands (e.g. “find” and “rsync”) provide options to avoid recursing into lower filesystems, but others (e.g. “du”) don’t make it so easy. A simple technique for getting around this is to use a bind mount. For example, after mount --bind / /mnt the /mnt directory shows you a view of the same filesystem as /, except you will notice that directories like /mnt/proc and (assuming your user files are on a separate volume) /mnt/home are empty. Or, to be more precise, those directories are now showing their original contents, unobscured by any other filesystem mounted on top of them. An example use of this is, the root partition on a machine might be filling up, and I want to know why. To narrow down which directories are using the space, I try to do du -ks /*/ but this wants to scan /home/ as well, which on this machine is a separate volume and therefore just adds greatly to the time taken without telling me anything relevant. But with the bind mount, I can do du -ks /mnt/*/ and it will only check the root volume. Another use of this is, as I mentioned above, you can see what is originally in the directories being used for mounting other filesystems. For example, one machine might normally have a network volume from another server mounted on a directory into which it regularly saves files. For some reason the network link might go down, and during that interval it blithely continues saving files into the local directory where the network volume was mounted, rather than the network volume itself. After the network mount is restored, you will probably want to check what files were accidentally saved locally, and move them onto the network volume where they belong. A bind mount lets you do this without disrupting access to the network volume. Then when you are finished with the bind mount, you can get rid of it in the usual way: umount /mnt

Browsing The Linux Kernel Sources Online

Red Hat Engineer Improves Math Performance of Glibc
by Peter Reutemann 03 Jan '15

03 Jan '15

"Siddhesh Poyarekar from Red Hat has taken a professional look into mathematical functions found in Glibc (the GNU C library). He has been able to provide an 8-times performance improvement to slowest path of pow() function. Other transcendentals got similar improvements since the fixes were mostly in the generic multiple precision code. These improvements already went into glibc-2.18 upstream. Siddhesh believes that a lot of the low hanging fruit has now been picked, but that this is definitely not the end of the road for improvements in the multiple precision performance. There are other more complicated improvements, like the limitation of worst case precision for exp() andlog() functions, based on the results of the paper Worst Cases for Correct Rounding of the Elementary Functions in Double Precision (PDF). One needs to prove that those results apply to the Glibc multiple precision bits." -- source: http://linux.slashdot.org/story/15/01/02/2025232 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Bots Scanning GitHub To Steal Amazon EC2 Keys

I only had S3 keys on my GitHub and they where gone within 5 minutes! Turns out through the S3 API you can actually spin up EC2 instances, and my key had been spotted by a bot that continually searches GitHub for API keys. Amazon AWS customer support informed me this happens a lot recently; hackers have created an algorithm that searches GitHub 24 hours per day for API keys.

The Case Against "Non-Commercial" Restrictions
by Lawrence D'Oliveiro 21 Dec '14

21 Dec '14

The Creative Commons <http://creativecommons.org/> family of copyright licences has become very popular for artworks, documentation and all kinds of creative works generally. But there are different kinds of Creative Commons (CC) licences, with additional qualifications, namely “BY” (attribution required, i.e. give credit to the creators), “SA” (sharealike or “copyleft”, i.e. if you redistribute, do it on the same terms it was given to you), “NC” (non-commercial use only) and “ND” (no derivatives--i.e. modified versions--allowed), and certain combinations thereof. These qualifications divide the CC licences into two categories: Free and non-Free. The non-Free CC licences are those including NC or ND or both, while the Free ones are the rest: * CC0 -- effectively public domain * CC-BY -- distribution with attribution required * CC-BY-SA -- sharealike distribution with attribution If you want to promote sharing and contribute to Free Culture, stick to these three licences. In particular, here <http://freedomdefined.org/Licenses/NC> is a detailed discussion of the NC restriction, and why it is such a bad idea. Most people who stick an NC licence on their work think in terms of preventing big commercial outfits from “ripping them off”. However, this licensing restriction may not achieve what you think it does, particularly since it is often unclear what constitutes “commercial” use anyway.

Does Anybody Like GNU Info?
by Lawrence D'Oliveiro 21 Dec '14

21 Dec '14

Anybody who has looked at Linux documentation on the command line would know about man pages, and quite likely about GNU info as well. The GNU project invented the “info” system as a (supposedly) superior replacement for man pages, but for some reason it never became that popular. I personally find it quite annoying to use, and it’s clear I’m not the only one. The GNU info system requires documentation to be written in Texinfo format, from which it can be generated in other formats displayable with the info command as well as other means. Now at least one GNU project, namely Emacs <http://lwn.net/Articles/625072/>, is contemplating moving away from maintaining its documentation in Texinfo format. The suggestion is to use AsciiDoc instead. This is one of a raft of newer, simpler markup formats that are designed so that even the source can be read and understood by ordinary humans, since the appearance of many of the markup sequences already gives some indication of their function in the layout. You may also have heard of Markdown (GitHub uses a flavour of this) and reStructedText (understood by Docutils/Sphinx, the standard toolset for Python documentation)--these are variations on the same idea. The LWN article has an error in it, though: the AsciiDoc package itself is not constrained to only generating HTML, it can output (shudder) DocBook SGML as well. And then there is another piece of software called Pandoc, which can convert between a whole range of different formats, including AsciiDoc.

Critical Git Security Vulnerability Announced
by Peter Reutemann 19 Dec '14

19 Dec '14

'Github has announced a security vulnerability and has encourage users to update their Git clients as soon as possible. The blog post reads in part: "A critical Git security vulnerability has been announced today, affecting all versions of the official Git client and all related software that interacts with Git repositories, including GitHub for Windows and GitHub for Mac. Because this is a client-side only vulnerability, github.com and GitHub Enterprise are not directly affected. The vulnerability concerns Git and Git-compatible clients that access Git repositories in a case-insensitive or case-normalizing filesystem. An attacker can craft a malicious Git tree that will cause Git to overwrite its own .git/config file when cloning or checking out a repository, leading to arbitrary command execution in the client machine. Git clients running on OS X (HFS+) or any version of Microsoft Windows (NTFS, FAT) are exploitable through this vulnerability. Linux clients are not affected if they run in a case-sensitive filesystem....Updated versions of GitHub for Windows and GitHub for Mac are available for immediate download, and both contain the security fix on the Desktop application itself and on the bundled version of the Git command-line client."' -- source: http://it.slashdot.org/story/14/12/18/2346238 Cheers, Petere -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Manufacturer's Backdoor Found On Popular Chinese Android Smartphone

Ryan Olson, intelligence director at Palo Alto, said the CoolReaper backdoor not only connects to a number of command and control servers, but is also capable of downloading, installing and activating any Android application without the user's permission. It also sends phony over-the-air updates to devices that instead install applications without notifying the user. The backdoor can also be used to dial phone numbers, send SMS and MMS messages, and upload device and usage information to Coolpad." -- source: http://it.slashdot.org/story/14/12/17/1815250 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Python Moving To Git
by Lawrence D'Oliveiro 16 Dec '14

16 Dec '14

About 5½ years ago, the decision was made <http://lwn.net/Articles/326201/> to use Mercurial as the preferred version-control system (VCS) for Python development. It was already clear at the time that there was a strong preference among developers for Git instead of Mercurial. And since that time, the dominance of Git has only grown. It appears that Mercurial is still the official VCS for at least the CPython core, but the Python project already has a GitHub area <https://github.com/python> which includes a “Semi-official read-only mirror of the CPython Mercurial repository”. I would suspect that a lot of their contributors are already doing their work in Git, and communicating with the upstream Mercurial repo using an addon like git-remote-hg, which makes it look just like a native Git repo. Now there is a plan to migrate at least some supporting repositories <http://lwn.net/Articles/624101/> <http://lwn.net/Articles/623905/> officially to Git, and also use GitHub to host these instead of at python.org. These stats from the PEP are quite interesting: The Open Hub (Previously Ohloh) statistics ... show that currently 37% of the repositories Open Hub is indexing is using git which is second only to SVN (which has 48%) while Mercurial has just 2% of the indexed repositories (beating only bazaar which has 1%). In addit[i]on to the Open Hub statistics a look at the top 100 projects on PyPI (ordered by total download counts) shows us that within the Python space itself there is a majority of projects using git: === ========= ========== ====== === ==== Git Mercurial Subversion Bazaar CVS None === ========= ========== ====== === ==== 62 22 7 4 1 1 === ========= ========== ====== === ==== Interesting that Subversion (aka SVN, an older, centralized, much less flexible version-control system) manages to handily beat Mercurial in non-Python-specific projects...

Ubuntu Gets Container-Friendly "Snappy" Core

Delivered as alpha code today, it's going to become a supported product, designed to compete with both CoreOS and Red Hat Atomic, the two leading container-friendly Linux approaches. Shuttleworth says it came about because Canonical found it had solved the "cloud" problems (delivering and updating apps and keeping security) by accident — in its work on a mobile version of Ubuntu.' -- source: http://linux.slashdot.org/story/14/12/09/2225210 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

POODLE Flaw Returns, This Time Hitting TLS Protocol
by Peter Reutemann 09 Dec '14

09 Dec '14

"If you patched your sites against a serious SSL flaw discovered in October you will have to check them again. Researchers have discovered that the POODLE vulnerability also affects implementations of the newer TLS protocol. The POODLE (Padding Oracle On Downgraded Legacy Encryption) vulnerability allows attackers who manage to intercept traffic between a user's browser and an HTTPS website to decrypt sensitive information, like the user's authentication cookies." -- source: http://it.slashdot.org/story/14/12/09/0423210 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Blockly Versus Scratch
by Lawrence D'Oliveiro 09 Dec '14

09 Dec '14

You may have heard of MIT Scratch <http://scratch.mit.edu/>, a visual programming language oriented to teaching children programming. Initially I was put off by the non-Free licence (you couldn’t redistribute modified code), but that seems to have gone now, and the source is available <https://github.com/LLK/Scratch_1.4> under completely Free licences, the core being GPLv2, plugins under an MIT licence, and support materials/samples under CC-BY-SA. Google has its own alternative along the same lines, but Web-based, called Blockly <https://code.google.com/p/blockly/>. And Barack Obama has successfully used it to become the first US president to write a computer program <http://www.engadget.com/2014/12/08/barack-obama-just-became-the-first-us-pr…>.

Linux 3.18 Released, Lockup Bug Still Present
by Peter Reutemann 08 Dec '14

08 Dec '14

"As anticipated, Linus Torvalds officially released Linux 3.18. The new version is now out there, though that nasty lockup issue has still yet to be resolved. Dave Jones is nearing the end of dissecting the issue, but since it also affects Linux 3.17 and not too many people seem to get hit by the lockups, Linus Torvalds decided to go ahead and do the 3.18 release on schedule. Linus was also concerned that dragging out the 3.18 release would then complicate the Linux 3.19 merge window due to the holidays later this month. Now the Linux 3.19 kernel merge window is open for two weeks of exciting changes." -- source: http://linux.slashdot.org/story/14/12/08/2020251 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Fwd: [NZOSS-Openchat] LCA 2015 Keynote Session - Q&A with Linus Torvalds
by Peter Reutemann 08 Dec '14

08 Dec '14

Excuse the cross posting, but here is an amazing incentive to get to LCA 2015 in Auckland this year. - Way, way back in 2003, at LCA in Perth, there was a Q&A session with Linus Torvalds, Bdale Garbee and Andrew Tridgell. It’s time for a follow-up so at LCA 2015 in Auckland it’s going to happen! The Q&A session is scheduled for 09:00 am Friday, 16 January 2015 and will be moderated by Bdale Garbee with the assistance of Andrew Tridgell. Helsinki-born Linus, who simply calls himself a Software Engineer, was the principle force behind developing the Linux kernel. It all started from an initial usenet posting in August of 1991 and made what has proved to be a historic debut with the release of version 1.0 on March 14 1994. In June 2003 Linus started working for Open Source Development Labs. After merging with the Free Standards Group it became the Linux Foundation where Linus continues to work as the project’s coordinator and is Chief Architect of the Linux kernel. In 2005, after criticism for for his use and alleged advocacy of BitKeeper, proprietary software for version-control in the Linux kernel, Linus wrote a free-software replacement for BitKeeper called GIT which is now the most widely-adopted version-control system for software development. Linus is an accomplished diver and in 2011, frustrated with the lack of decent divelog software on Linux, he developed Subsurface (http://subsurface-divelog.org/) an Open Source divelog program that runs on Windows, Mac and Linux. We know that there are a number of beautiful diving spots not too far from Auckland... The LCA 2015 Auckland team would like to thank the Linux Foundation for their assistance in making this possible. -------------------------------------------- Steven Ellis - Technical Director OpenMedia Limited - The Home of myPVR email - steven(a)openmedia.co.nz _______________________________________________ Openchat mailing list Openchat(a)lists.nzoss.org.nz http://lists.nzoss.org.nz/mailman/listinfo/openchat -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Hi everyone >From what I can gather, the main reason for moving the mailing list (aggressive spam filtering), no longer seems to be an issue.

mailing list difficulties
by Ian Young 29 Nov '14

29 Nov '14

Greets, On the last occasion I tried to send a message to the list, it was impounded as there was a suspect word or somesuch in the subject line. Robo was wrong, utterly nonsensical. I think there was some reference in the rejection blurb to (possibly non-existent?) moderation. The message never appeared afaik. Never got around to following it up, but it was a nuisance. Subsequently I stopped bothering to post. And as I press Send now, I find myself wondering whether this message will ever appear. ~ IsY

Computer History
by Lawrence D'Oliveiro 29 Nov '14

29 Nov '14

Anybody interested in talks by and about computer pioneers should look at this YouTube channel <http://www.youtube.com/user/ComputerHistory>, run by the Computer History Museum in Mountain View. All kinds of fun stuff, from the experience of building a working version of Charles Babbage’s Difference Engine No 2 (designed in the 1830s), to the 30th anniversary of the Cray-1 supercomputer, to an interview with Ward Cunningham, inventor of the wiki. And if you want to see how far computer graphics has come, try this one: <http://www.youtube.com/user/VintageCG/>. Some old classics there. But boy, have we come a long way since characters made out of spheres and cylinders...

Hi wlug folks, FYI: The latest release of Bitcoin is currently version 0.9.3 which was released 27 September 2014. You can download a suitable binary version of the Bitcoin Core from: https://www.bitcoin.org/en/download It is open source code and you can obtain it from: https://github.com/bitcoin/bitcoin cheers, Ian. PS: This e-mail is a test to see if the spam filtering software blocks it being distributed to the wlug email list. From my experience about a year ago, I found that mails that contained the word "bitcoin" would be blocked.

Crowdfunding project promises a “laptop that respects essential freedoms”
by Peter Reutemann 22 Nov '14

22 Nov '14

'What price can you put on freedom? If you’re talking about software freedom, a new San Francisco-based computer company prices it at $1,949 and up. Purism has turned to the crowdfunding site Crowd Supply to fund and launch its first-ever product—a laptop that's as open source friendly as it is technically feasible. Advertised as a "Free and Open Source laptop that respects your essential freedoms," Purism’s Librem 15 laptop, now in prototype and ready for manufacture, is designed to run entirely with open source software, requiring no proprietary drivers. The only proprietary code on the laptop resides in its Intel firmware. ... It will ship with Purism’s own distribution of GNU/Linux based on Trisquel—an Ubuntu derivative that only includes free software. Purism will ship the Librem with Tor installed and turned on by default.' -- source: http://goo.gl/8COuog Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Using a password manager on Android? It may be wide open to sniffing attacks
by Peter Reutemann 22 Nov '14

22 Nov '14

'In early 2013, researchers exposed some unsettling risks stemming from Android-based password managers. In a paper titled "Hey, You, Get Off of My Clipboard," they documented how passwords managed by 21 of the most popular such apps could be accessed by any other app on an Android device, even those with extremely low-level privileges. They suggested several measures to help fix the problem. Almost two years later, the threat remains viable in at least some, if not all, of the apps originally analyzed. An app recently made available on Google Play, for instance, has no trouble divining the passwords managed by LastPass, one of the leading managers on the market, as well as the lesser-known KeePassDroid. With additional work, it's likely that the proof-of-concept ClipCaster app would work seamlessly against many other managers, too, said Xiao Bao Clark, the Australia-based programmer who developed it. While ClipCaster does nothing more than display the plaintext of passwords that LastPass and KeePassDroid funnel through Android handsets, a malicious app with only network privileges could send the credentials to an attacker without the user having any idea what was happening.' -- source: http://goo.gl/CsjkC8 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

A Brilliant Mind: SUSE's Kernel Guru Speaks
by Peter Reutemann 20 Nov '14

20 Nov '14

"The man who in every sense sits at the nerve centre of SUSE Linux has no airs about him. At 38, Vojtch Pavlík is disarmingly frank and often seems a bit embarrassed to talk about his achievements, which are many and varied. He is every bit a nerd, but can be candid, though precise. As director of SUSE Labs, it would be no exaggeration to call him the company's kernel guru. Both recent innovations that have come from SUSE — patching a live kernel, technology called kGraft, and creating a means for booting openSUSE on machines locked down with secure boot, have been his babies." -- source: http://linux.slashdot.org/story/14/11/20/203259 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Jolla Crowdfunds Its First Tablet
by Peter Reutemann 19 Nov '14

19 Nov '14

'Jolla is another rising star in the tech world, having recently expanded its smartphone sales into more countries across the globe. Jolla's Sailfish OS is based on the Linux kernel, and considered by many to be a direct successor to Nokia and Intel's MeeGo and the N9 mobile phone. Its software is based on the open-sourced components of MeeGo. Now, the company is ready to start production of its first tablet. They're crowdfunding it, and they blew past their $380,000 goal in about two hours. The tablet has a 7.9-inch screen with a resolution of 2048 x 1536. It's powered by a 1.8GHz 64-bit quad-core Intel processor, comes with a 32GB of storage, an SD card slot, 2GB of RAM and a 5MP rear camera. Judging by its size, we can see this will rival the iPad Mini the new Nokia N1. While there aren't too many Sailfish-specific apps available, as with the phone, Jolla's tablet will be compatible with Android apps.' -- source: http://linux.slashdot.org/story/14/11/19/1343250 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Fedora Looks To Make /usr World-Readable
by Peter Reutemann 17 Nov '14

17 Nov '14

"Fedora developers are looking at requiring all files that be placed in /usr world-readable. Developers are seeking a mandate that all Fedora packages must not install any non-world-readable files within /usr. Right now some Fedora packages do not honor this and restrict permissions to certain files/directories. Stakeholders are after making the user directory world-readable since containerized copies of Fedora can have the directory bind-mounted into the container, support for virtualization use-cases, and for better systemd handling.
