Automatically enabling numlock in an X11 session, *without* a window manager
by Eric Light 12 Jul '15

12 Jul '15

I just spent a whole day on this, so I wanted to share it with some people who would understand the struggle. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- The Scenario:You have some remote users who need to securely access your application, delivered in plaintext over SSH. To do this, they get a thin client delivered to them, fully set up. However, most of these users have very limited computer knowledge, so they need the application to be as simple and responsive as possible. The Solution: The thin client needn’t have Windows on it. Also Windows is slow (wimpy thin clients), prone to fickleness (“have you tried turning it off and on again?”), and insecure (no antivirus or even security updates are installed on the thin clients). In fact, these users are so limited they shouldn’t even have a window manager at all. No need to resize, copy & paste, or multitask – a single application window would be ample. So let’s install just a plain edition of Debian, then run sudo apt-get install xinit, to get the barest of essential graphical libraries. The Challenge: Set up our thin clients, based on a Linux install, such that it boots quietly and quickly, automatically logs in as the user, waits for the network, and launches a Putty window. When the user quits Putty, they should only have two options: launch a new Putty session, or shutdown the computer. The Yak: Because there’s no window manager, every Putty window is launched in its’ own session. A new X11 session has number lock disabled by default. The standard answer for controlling numlock, a program named “numlockx”, works just fine – however, because there’s no window manager, you can only send a single command to the X11 session. Thus, you can *either* turn on NumLock, *or *you can launch Putty. Shaving the Yak: 1) Create the file ~/putty This file contains the lines: numlockx on & putty -load {your saved session} 2) Launch the file with: xinit ~/putty $* -- The End: Now you can set up your silent boot (/etc/sysctl.conf -> kernel.printk), your automatic login (/etc/system/system/getty(a)tty1.service.d/autologin.conf), and your auto-start locked-down profile (~/.profile) with other tutorials available on the internet. (PS they boot in about ten seconds, and our guinea pig testers love them) Eric

Customizing The Compose Key
by Lawrence D'Oliveiro 09 Jul '15

09 Jul '15

The Compose key <http://wiki.wlug.org.nz/ComposeKey> is probably the best way of typing less common characters available on any OS. It lets you use mnemonic sequences that actually bear some relationship to the character you are trying to enter, instead of having to remember numeric codes. You will find there a list of the characters that I found most useful, though the complete set will be in the Compose file for your chosen locale. You can even add your own compose sequences. This tutorial for KDE <https://userbase.kde.org/Tutorials/ComposeKey/en> covers the procedure. Basically, you create a file “.XCompose” in your home directory, include a system Compose file to inherit the standard sequences, and put in extra compose-key definitions using the same syntax as the system Compose files. I had got this far, but then was baffled as to why KDE seemed to pay no attention whatsoever to my custom compose-key sequences. It turns out you need to define additional environment variables to get Qt/KDE- and GTK-based apps to use the X11 input method that actually reads the .XCompose file. Put these in your .bashrc: export GTK_IM_MODULE=xim export QT_IM_MODULE=xim and when you logout and login again, it should all work. For example, in my .XCompose, I have the line <Multi_key> <p> <i> which lets me type compose-p-i to produce “π”.

Ah, The Memories...

In the wake of the latest round of Microsoft’s layoffs, it seems apropos to remember the time they held a mock funeral for their competition at the time of the Windows Phone 7 launch: <http://appleinsider.com/articles/10/09/10/microsoft_employees_hold_funeral_…>. “Research firm Gartner predicted ... Nokia Symbian and Google Android [would be] first and second with 30.2 percent and 29.6 percent [market share] respectively [in 2014].” Did anybody notice any Symbian phones still on sale?

Debian To Switch From Libav Back To ffmpeg
by Lawrence D'Oliveiro 09 Jul '15

09 Jul '15

I’ve been using FFmpeg for years. I always built it from source, because I was aware that prebuilt distro packages were 1) well behind the latest development tree, and 2) likely to leave out features because of patent issues. So I hardly noticed the whole Libav fork issue <https://lwn.net/Articles/433347/>. I was dimly aware that my Debian system had these “libav” packages on it, that looked and behaved just like FFmpeg in everything but name. But I hardly ever used them—not directly. Then, last year, I found out a bit more about what really happened <https://lwn.net/Articles/607591/>, and why Debian went with the fork. Can you say “conflict of interest”? (Well, that’s how it looks like to me.) So now, Debian has officially decided to return to the original FFmpeg project <http://lwn.net/Articles/650495/>.

Amazon's New SSL/TLS Implementation In 6,000 Lines of Code
by Peter Reutemann 01 Jul '15

01 Jul '15

'Amazon has announced a new library called "s2n," an open source implementation of SSL/TLS, the cryptographic security protocols behind HTTPS, SSH, SFTP, secure SMTP, and many others. Weighing in at about 6k lines of code, it's just a little more than 1% the size of OpenSSL, which is really good news in terms of security auditing and testing. OpenSSL isn't going away, and Amazon has made clear that they will continue to support it. Notably, s2n does not provide all the additional cryptographic functions that OpenSSL provides in libcrypto, it only provides the SSL/TLS functions. Further more, it implements a relatively small subset of SSL/TLS features compared to OpenSSL.' -- source: http://it.slashdot.org/story/15/07/01/0214248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GMT Versus UTC
by Lawrence D'Oliveiro 01 Jul '15

01 Jul '15

It still seems to be common among groups outside the computing and scientific worlds to talk about “GMT” rather than “UTC”. The trouble with “GMT” is that it doesn’t seem to be clearly defined; it might or might not differ from UTC by up to 0.9 seconds. The (unadjusted) time reference defined by an official collection of atomic clocks worldwide is called “TAI”. This pays no heed to the slowing rotation of the Earth. Astronomers prefer a time reference called “UT1”, which is based on the actual rotation of the Earth (subject to some time-averaging, I think). The definition of “UTC” comes from TAI, adjusted by applying leap seconds. These accumulate as needed so as to keep UTC within 0.9 seconds of UT1, and we are currently up to 36 of them. That is, at 0:00:00 UTC today, TAI was actually 0:00:36. The trouble with GMT is that it is not officially clear whether it is the same as UT1, or the same as UTC. Given that it was originally defined at the Greenwich Observatory, which was (is?) run by astronomers, one would think they would make it the same as UT1. But the practical fact is, our usual everyday timekeeping is based on standard time zones, which are all defined as whole-second (indeed, whole multiples of a half-hour) offsets from UTC.

Doing For Video What PulseAudio Did For Audio
by Lawrence D'Oliveiro 01 Jul '15

01 Jul '15

Pinos is a project to allow better handling of video input across multiple applications. Pinos will make it easier to switch cameras in applications and for the same camera source to be used by multiple apps simultaneously, there will be support for multiple types of video inputs, GStreamer integration, and some audio support. Pinos should allow better screencasting within GNOME 3, video support for desktop sandboxes, and many other potential use-cases. In an email, Christian mentioned why it didn't end up being called PulseVideo over name squatting. <http://phoronix.com/scan.php?page=news_item&px=Fedora-Pinos-Announced>

MAC Address Privacy Standard Coming
by Lawrence D'Oliveiro 26 Jun '15

26 Jun '15

Every network interface (wired or wireless) on every networked device in the world is assigned a unique 48-bit identifier—the MAC address—burned into its ROM at manufacturing time. While it’s often (usually?) possible to change this via the software driver, nobody thought of it as a big deal. Until recently, when certain, ahem, spying revelations have woken people to the privacy implications of being able to track a machine, particularly on wi-fi networks, based on its unique MAC address. And so some folks at the Internet Engineering Task Force have been doing experiments to determine whether randomly changing these addresses would cause hiccups for any network protocols. The good news is that the answer so far seems to be “no”. <http://www.theregister.co.uk/2015/06/26/mac_address_privacy_inches_towards_…>

How Long Should Microsoft Be Forced To Provide Windows XP Support?
by Lawrence D'Oliveiro 26 Jun '15

26 Jun '15

Reading about how the US Navy <http://www.theregister.co.uk/2015/06/25/us_navy_windows_xp_support/> has signed a contract to get continuing support from Microsoft for Windows XP, led me to wonder how long is a “reasonable” interval for Microsoft to continue to provide patches and updates for this ancient OS. My reasoning is thus: Windows XP is still under copyright. Microsoft still considers it to be its “intellectual property”. The term “property” is deliberately used, to convey the idea of something owned by Microsoft, not by you, the customer. All you get when you buy it is a “licence”, not ownership. But with property rights come property responsibilities. If your property is causing harm or nuisance to others, the onus is on you to fix it. Therefore, Microsoft’s responsibilities over its “intellctual property” should continue just as long as it claims those property rights. If unmaintained Windows XP machines are being exploited as parts of botnets or spam relays or virus vectors or whatever, the onus for fixing those problems should be on the property owner, right? Under current US copyright law, that duration would be 90 years from when Windows XP was first published, or, by my reckoning, the year 2091.

'On June 17th, Google did not announce (the news broke) that the DARPA affiliated corporation has been silently downloading audio listeners onto every computer that has Chrome.

Resurrecting The SuperH Architecture
by Lawrence D'Oliveiro 18 Jun '15

18 Jun '15

I guess this is more of an embedded thing, but ... <http://lwn.net/Articles/647636/> “He then asked what constitutes the minimal system that can run Linux. All that is really needed, he said, is a flat, 32-bit memory address space, a CPU with registers to hold instructions, some I/O and storage (from which the kernel and initramfs can be loaded), and a timer for interrupts. That plus GCC is sufficient to get Linux running—although it may not be fast, depending on the specifics. One does not even need a cache, floating-point unit, SMP, or a memory-management unit (MMU).” “The other main advantage of the J2 project is that the work for implementing SuperH support is already done in the kernel, GCC, GDB, strace, and most other system components.” “The project has thus "inherited" an excellent ISA, and has even been in contact with many of the former Hitachi employees that worked on SuperH.” “...there are many ASIC vendors who are happy to produce low-cost chips on their older equipment because the cost of retooling a plant is exorbitant. A 180nm implementation of the J2 design, he said, costs around three cents per chip, with no royalties required. "That's disposable computing at the 'free toy inside' level."” “At the end of the talk, an audience member voiced concern that SuperH was old enough that support for it is unmaintained in a lot of projects. He suggested that the J2 team might need to act quickly to stop its removal. Landley noted that, indeed, the latest buildroot release did remove SuperH support, "but we're trying to get them to put it back now."”

TRIM and Linux: Tread Cautiously, and Keep Backups Handy
by Peter Reutemann 16 Jun '15

16 Jun '15

'Algolia is a buzzword-compliant ("Hosted Search API that delivers instant and relevant results") start-up that uses a lot of open-source software (including various strains of Linux) and a lot of solid-state disk, and as such sometimes runs into problems with each of these. Their blog this week features a fascinating look at troubles that they faced with ext4 filesystems mysteriously flipping to read-only mode: not such a good thing for machines processing a search index, not just dishing it out. "The NGINX daemon serving all the HTTP(S) communication of our API was up and ready to serve the search queries but the indexing process crashed. Since the indexing process is guarded by supervise, crashing in a loop would have been understandable but a complete crash was not. As it turned out the filesystem was in a read-only mode. All right, let's assume it was a cosmic ray :) The filesystem got fixed, files were restored from another healthy server and everything looked fine again. The next day another server ended with filesystem in read-only, two hours after another one and then next hour another one. Something was going on. After restoring the filesystem and the files, it was time for serious analysis since this was not a one time thing. The rest of the story explains how they isolated the problem and worked around it; it turns out that the culprit was TRIM, or rather TRIM's interaction with certain SSDs: "The system was issuing a TRIM to erase empty blocks, the command got misinterpreted by the drive and the controller erased blocks it was not supposed to. Therefore our files ended-up with 512 bytes of zeroes, files smaller than 512 bytes were completely zeroed. When we were lucky enough, the misbehaving TRIM hit the super-block of the filesystem and caused a corruption." Since SSDs are becoming the norm outside the data center as well as within, some of the problems that their analysis exposed for one company probably would be good to test for elsewhere. One upshot: "As a result, we informed our server provider about the affected SSDs and they informed the manufacturer. Our new deployments were switched to different SSD drives and we don't recommend anyone to use any SSD that is anyhow mentioned in a bad way by the Linux kernel."' -- source: http://linux.slashdot.org/story/15/06/16/201217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

They need time to see what the future holds for them. Bill Rosoman

I have the time and knowledge to open the lab. I've emailed Mike regarding this but recieved no reply. Rod has expressed interest in help running also. I'm willing to open the lab twice a week from 9-12. With more people I would love to open it from 2:30 till 5pm for primary and intermediate. It's a great resource and it makes me sad to see it closed.

Microsoft To Support SSH In Windows and Contribute To OpenSSH
by Peter Reutemann 03 Jun '15

'Microsoft has announced plans for native support for SSH in Windows. "A popular request the PowerShell team has received is to use Secure Shell protocol and Shell session (aka SSH) to interoperate between Windows and Linux – both Linux connecting to and managing Windows via SSH and, vice versa, Windows connecting to and managing Linux via SSH. Thus, the combination of PowerShell and SSH will deliver a robust and secure solution to automate and to remotely manage Linux and Windows systems." Based on the work from this new direction, they also plan to contribute back to the OpenSSH project as well.' -- source: http://news.slashdot.org/story/15/06/02/1950234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Debian8 Gnome3 desktop - Debian Installer problem
by Ian Stewart 26 May '15

26 May '15

Hi, At last nights wlug meeting I did a show and tell of my recent adventures with downloading and installing Debian 8 Live + non-free. I had encountered a problem with the Gnome3 desktop in that the Debian Installer application, which displays itself in full-screen mode, was not positioned correctly. As a result the Debian Installer applications "continue" and "go back" buttons are off the bottom of the display. Today I bumped into Ian Young, who provided a solution to this Gnome3 / Debian Installer problem. The workaround is to type Alt+Spacebar to open up a menu. Then select "Move to Workspace Down". The debian installer is placed into the second display workspace and in full-screen mode it is now positioned correctly so all pushbuttons may be accessed. I've tested out the Debian8 Installer on the KDE, xfce, LXDE, and Mate desktop environments and they position the Debian Installer window correctly. Also at last nights meeting I suggested the following command to copy the .iso file to a USB stick as device sdc... $ sudo dd if="debian-live-8.0.0-amd64-gnome-desktop nonfree.iso" of=/dev/sdc bs=4M; sync An alternative to this, which I tested out OK today is... $ sudo cp "debian-live-8.0.0-amd64-gnome-desktop nonfree.iso" /dev/sdc ...wishing you all the best with Debian8. cheers, Ian.

'Logjam' Vulnerability Threatens Encrypted Connections
by Peter Reutemann 22 May '15

22 May '15

'A team of security researchers has revealed a new encryption vulnerability called 'Logjam,' which is the result of a flaw in the TLS protocol used to create encrypted connections. It affects servers supporting the Diffie-Hellman key exchange, and it's caused by export restrictions mandated by the U.S. government during the Clinton administration. "Attackers with the ability to monitor the connection between an end user and a Diffie-Hellman-enabled server that supports the export cipher can inject a special payload into the traffic that downgrades encrypted connections to use extremely weak 512-bit key material. Using precomputed data prepared ahead of time, the attackers can then deduce the encryption key negotiated between the two parties." Internet Explorer is the only browser yet updated to block such an attack — patches for Chrome, Firefox, and Safari are expected soon. The researchers add, "Breaking the single, most common 1024-bit prime used by web servers would allow passive eavesdropping on connections to 18% of the Top 1 Million HTTPS domains. A second prime would allow passive decryption of connections to 66% of VPN servers and 26% of SSH servers. A close reading of published NSA leaks shows that the agency's attacks on VPNs are consistent with having achieved such a break." Here is their full technical report (PDF).' -- source: http://it.slashdot.org/story/15/05/20/1258251 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/

The cause and fix have materialized but it hasn't yet worked its way out into the mainline kernel, thus users should be warned before quickly upgrading to the new kernel on systems with EXT4 and RAID0.' -- source: http://hardware.slashdot.org/story/15/05/21/1324229 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

"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/

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/>

Debian 8 Jessie Released
by Peter Reutemann 26 Apr '15

26 Apr '15

"After almost 24 months of constant development, the Debian project is proud to present its new stable version 8 (code name Jessie), which will be supported for the next five years thanks to the combined work of the Debian Security team and the Debian Long Term Support team. (Release notes.) Jessie ships with a new default init system, systemd. The systemd suite provides features such as faster boot times, cgroups for services, and the possibility of isolating part of the services. The sysvinit init system is still available in Jessie.

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.

"The Beta version of the forthcoming Fedora 22 Linux computer operating system was released on April 21, as reported by Softpedia, but it is time now to look at some of the features to be implemented in the next major release of the Red Hat-sponsored distribution, Fedora 23. Therefore, among the highlights announced for Fedora 23, we can mention that the next-generation Wayland display server will be used by default for the Workstation edition, which will most probably be built around the GNOME 3.18 desktop environment. Python 3 will also be used by default in the Workstation edition, and a Vagrant image will be provided for Fedora 23 Atomic Host and Cloud spins. The Vagrant boxes have been designed to be compatible with the Oracle VirtualBox and KVM (Kernel-based Virtual Machine) virtualization software." -- source: http://news.softpedia.com/news/Fedora-23-to-Use-Wayland-and-Python-3-by-Def… 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/

Development Activity In LibreOffice Versus OpenOffice
by Lawrence D'Oliveiro 22 Apr '15

22 Apr '15

LWN has a comparison <http://lwn.net/Articles/637735/> of the relative health of the two main OpenOffice forks. Summary: in the last 4½ years, one project has done precisely two releases, while the other has managed over a dozen. In the last year, one has received contributions from just 16 developers, while the other has benefited from the work of around 16 times that number.

NCR Unveils Android For ATMs
by Lawrence D'Oliveiro 16 Apr '15

16 Apr '15

NCR is offering an Android-based platform for operating cash machines, called “Kalpana”. Unlike the multiple gigabytes of RAM needed to run Windows, this one only needs a fraction of a gigabyte. The company is also claiming significantly lower maintenance costs. <http://www.theregister.co.uk/2015/04/15/ncr_android_atm/> However, open-source or not, I’m still not convinced the question has been fully answered: what happens to devices running older versions once the vendor drops support?

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/>

We'll see. Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously "small" is all relative. It's still over 10k non-merge commits.

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

The open source project hosting service will no longer be accepting new project submissionsas of today, will no longer be accepting updates to existing projects from August 24, and will be closed entirely on January 25, 2016." -- source: http://arstechnica.com/information-technology/2015/03/google-to-close-googl… Well, there goes another free service... Now I have to move my remaining projects over to github. Grr...

OpenSSL To Undergo Massive Security Audit
by Peter Reutemann 12 Mar '15

"Now that its codebase is finally viewed as stable, OpenSSL is getting a good top-to-bottom once-over in the form of a sweeping audit. As part of the Linux Foundation's Core Infrastructure Initiative, the foundation and the Open Crypto Audit Project are sponsoring and organizing what may arguably be the highest-profile audit of a piece of open-source software in history. The audit itself will be conducted by the information assurance organization NCC Group, and its security research arm, Cryptography Services, will carry out the code review of OpenSSL's 447,247 line codebase over the next several months." -- source: http://tech.slashdot.org/story/15/03/12/1928259 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174
