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>.

Linus Torvalds Debuts First Linux 4 Release Candidate
by Paul Wilson 24 Feb '15

24 Feb '15

"The Linux 3.x kernel family is no more. Long Live Linux 4! The Linux 3.x kernel family first officially debuted <http://www.datamation.com/open-source/linux-3.0-debuts-with-xen-integration…>on July 22, 2011. Linux 3.0 was the first major version change for Linux since the 2.6 kernel debuted in December of 2003. While Linux 2.6 was a major milestone that signified a break with the past, Linux 3.0 really was just the renumbered Linux 2.6.40 kernel. In the same manner the Linux 4.0 kernel is the continuation of Linux 3.x and is the renamed Linux 3.20."

“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.

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.

The date given in the title is 1976, but he repeatedly makes remarks in the talk that point to the year actually being 1974.

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

SPDY, which is not an acronym but just a short version for the word "speedy," is a protocol developed primarily at Google to improve browsing by forcing SSL encryption for all sites and speeding up page loads.

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

Is Modern Linux Becoming Too Complex?
by Peter Reutemann 11 Feb '15

11 Feb '15

'Debian developer John Goerzen asks whether Linux has become so complex that it has lost some of its defining characteristics. "I used to be able to say Linux was clean, logical, well put-together, and organized. I can’t really say this anymore. 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.)

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

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.

Android tethering: fix IP address of client using Mac ID?

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

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.

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

Linus Fixes Kernel Regression Breaking Witcher 2
by Peter Reutemann 24 Jan '15

24 Jan '15

'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

"I often ask myself what the current state of video editing is for free and open source software (FOSS). Here are my thoughts.

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".

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

"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. In the post he also mentions how the older Red Star 2.0 shipped with another schoolboy mistake: /etc/rc.d/rc.sysinit was world-writeable." -- source: http://linux.slashdot.org/story/15/01/11/032207 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Rust Programming Language Reaches 1.0 Alpha
by Peter Reutemann 11 Jan '15

11 Jan '15

"Rust, a new a systems programming language with a focus on safety, performance and concurrency, has released the 1.0 alpha version of the language. This means that the language and core libraries are feature-complete for the 1.0 release. In practical terms, this means that the rate of change experienced by early adopters will slow down dramatically and major breaking changes should be very rare (during the alpha cycle some major changes may still occur if considered necessary). The language will stabilize further when the beta stage is reached (planned for six weeks from now)." -- source: http://developers.slashdot.org/story/15/01/11/0254252 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

USB 3.1 & Type C Connectors
by Lawrence D'Oliveiro 11 Jan '15

11 Jan '15

At the recent CES exhibition in Las Vegas, there was being shown a lot of new hardware taking advantage of the new USB specs <http://arstechnica.com/gadgets/2015/01/usb-3-1-and-type-c-the-only-stuff-at…>. 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

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. Privacy-conscious people rely on it to help cloak their identities and prevent websites from tracking their previous steps. Now, a software consultant has devised a simple way websites can in many cases bypass these privacy modes unless users take special care." -- source: http://goo.gl/jnkuaA Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

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

Life With Debian Unstable

Doing an “apt-get dist-upgrade -s” on a Debian Unstable system is currently telling me it wants to remove most of KDE. This even though I tried an apt-get update on two different repo mirrors. I think I’ll leave it, and check again in a few days...

Browsing The Linux Kernel Sources Online
by Lawrence D'Oliveiro 06 Jan '15

06 Jan '15

You may remember at one of my presentations I was trying to bring up a website that allowed browsing and linking to the Linux kernel sources online, complete with cross references and search. However, that original site seems to have long gone. The good news is, another site <http://lxr.free-electrons.com/> is offering exactly the same thing, and I think they’re using the same software (developed by people at Oslo University in Norway) as well.

AMD Catalyst Linux Driver Catching Up To and Beating Windows
by Peter Reutemann 03 Jan '15

'Along with the open-source AMD Linux driver having a great 2014, the AMD Catalyst proprietary driver for Linux has also improved a lot. Beyond the open-source Radeon Gallium3D driver closing in on Catalyst, the latest Phoronix end-of-year tests show the AMD Catalyst Linux driver is beating Catalyst on Windows for some OpenGL benchmarks. The proprietary driver tests were done with the new Catalyst "OMEGA" driver. Is AMD beginning to lead real Linux driver innovations or is OpenGL on Windows just struggling?' -- source: http://linux.slashdot.org/story/15/01/03/1426208 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

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
by Peter Reutemann 03 Jan '15

03 Jan '15

'As one developer found out, posting your Amazon keys to GitHub on accident can be a costly mistake if they are not revoked immediately. "When I woke up the next morning, I had four emails from Amazon AWS and a missed phone call from Amazon AWS. Something about 140 servers running on my AWS account. What? How? 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. Once it finds one it spins up max instances of EC2 servers to farm itself bitcoins."' -- source: http://it.slashdot.org/story/15/01/02/2342228 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174
