PatchSee Ethernet Cables
by Lawrence D'Oliveiro 23 Sep '15

23 Sep '15

The unique selling point is the special LED tool that, when plugged in to one end, lights up the other end. So you can tell where your cables run without having to colour-code or label them. But is it worth the cost? <https://www.youtube.com/watch?v=PETJpmxiyOY>

Copying from a pdf, removing EOL and spaces
by Roderick Aldridge 23 Sep '15

23 Sep '15

Hi everyone I want to copy an extract from a .pdf file. When I select some text to copy and paste it puts each word followed by two spaces on a separate line. Do you know a better way to extract some text from a .pdf? Alternatively what is an easy way to remove the space and EOL to reformat the text in a readable format? I am sure there are several, but I would appreciate a really easy one. TIA Roderick

Keith Packard On X11
by Lawrence D'Oliveiro 19 Sep '15

19 Sep '15

A half-hour talk from “Mr X11” himself, Keith Packard <http://phoronix.com/scan.php?page=news_item&px=KeithP-Sustaining-X>. Notable points: * The original MIT X Consortium was dominated by the proprietary UNIX workstation vendors, who were all trying to lock in their own customers into their own ways of doing things. These “UNIX Wars” led to the whole workstation market imploding, letting Microsoft take over with Windows NT. * XFree86 was, in the beginning, like a “rebel alliance”, trying to bring X11 to commodity PC hardware. They were shunned for many years by the X Consortium. Of course this changed after all the UNIX vendors went under. Later, the revitalized X Consortium became a home for the X11 developer community which left the inflexibilities of the XFree86 corporate organization behind. * Over the last decade, the X server has become less and less of an operating system in its own right. Hardware-specific graphics drivers have been moved into the Linux kernel, leaving the X userland code to focus on the hardware-independent implementation layers. * Programs written to work with X11 nearly thirty years ago still work today. Even with all the reorganization and rewrites, X11 still remains fully backward-compatible. Which is more than Microsoft Windows can manage. * Keith made it clear he prefers GPL-style (copyleft/sharealike) licences to MIT/BSD style ones. Net contributors of code tend to prefer the former, while net consumers of code (those who don’t want to give back to the community) tend to favour the latter. In other words, freeloaders.

Linux 4.3 Bringing Stable Intel Skylake Support, Reworked NVIDIA Driver

'Mr. Torvalds has released Linux 4.3-rc1 this weekend. He characterized the release as "not particularly small — pretty average in size, in fact.

There are a number of new user-facing features including stabilized Intel "Skylake" processor support, initial AMD R9 Fury graphics support, SMP scheduler optimizations, file-system fixes, a reworked open-source NVIDIA driver, and many Linux hardware driver updates.' -- source: http://linux.slashdot.org/story/15/09/13/1521216 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/

Stopping A Command-Line Loop
by Lawrence D'Oliveiro 12 Sep '15

12 Sep '15

I was playing a bunch of several dozen MP3 files in sequence using a command like for f in *.mp3; do ffplay -autoexit "$f"; done Then half-way through I decided to stop it. Trouble was, every time I hit CTRL/C, it killed the playback of the current MP3 file, but the loop just went on to the next one. Finally I hit CTRL/Z. This suspended the entire command, putting it in the background, and returned me to the command prompt. Then I was able to type kill %1 to kill the background job. In future, I will remember to use a command more like for f in *.mp3; do ffplay -autoexit "$f" || break; done This terminates the loop if the playback of a file aborts with an error.

New Release of the Trinity Desktop Environment
by Peter Reutemann 06 Sep '15

'A new release of the Trinity Desktop Environment (TDE) is out. TDE is "a computer desktop environment for Unix-like operating systems with a primary goal of retaining the function and form of traditional desktop computers" which translates into a fully functional KDE 3 style Desktop. Something is missing in the new generation of desktop environments, since some people (perhaps more than "some") feel at home with Gnome 2 or KDE i3. They have repositories for Debian and Ubuntu-based distros. I'm now using it on Ubuntu 15.04, amazed about how well-planned things were in the previous generation of DE. We may have gained some things with Gnome 3 and Plasma 5, but we lost a lot of good features too.

LILO Development Coming To An End
by Lawrence D'Oliveiro 01 Sep '15

01 Sep '15

<http://phoronix.com/scan.php?page=news_item&px=LILO-Bootloader-EOY> Is anybody still using LILO (the “LInux LOader”)? That was the Linux-specific bootloader from the early days, before GRUB (the “GRand Unified Bootloader”) came on the scene. I remember one difference was that LILO compiled its configuration into the bootloader binary at installation time. That way, if you made any errors in the configuration, you usually discovered that immediately. Whereas with GRUB, you only found this out when your machine failed to boot. Though with GRUB 2 commonplace nowadays, I haven’t felt the need to configure anything as yet. It seems smart enough to figure it out all by itself. :)

"Hack" Typeface Is Open Source, Easy On the IDEs
by Peter Reutemann 31 Aug '15

31 Aug '15

"Ars Technica writes that "At SourceFoundry.org this week, programmer Chris Simpkins debuted the 2.0 version of Hack, an open-source typeface designed specifically for use in source code." The revamped font is" characterized by a large x-height, wide aperture, and low contrast design in order to be "highly legible" at common coding text sizes," and the font specimen shows how legible it is right down to downright tiny sizes, though Simpkins says the sweet spot is between 8 and 12 pixels. " -- source: http://developers.slashdot.org/story/15/08/30/1733217 Very subtle differences in comparison to "monospace", from a quick comparison: - the dash "-" is longer - the "*" has five points rather than six - the "i" looks more like an "l" (not so sure about this change, though) - the stroke inside the zero is more pronounced Using Hack in a terminal seems a bit clearer than monospace.

KDE Is Broken In Debian Unstable

Looks like KDE is in the middle of a major transition in Debian Unstable at the moment.

This morning I did another update, and was presented with a new “flat” look after a GUI login. Checking my package versions, I believe I have some parts of KDE 5, but not all (yet). I might do another update this evening. Luckily my backup machine can still fulfil most of its functions without a GUI...

Major Android remote-access vulnerability is now being exploited
by Peter Reutemann 25 Aug '15

25 Aug '15

"Based on anonymized data collected from users of an app designed to check for a newly revealed vulnerability in many Android devices, Check Point discovered that one application in the Google Play store is exploiting the vulnerability to gain a high level of access to the Android OS, bypassing user permissions—and bypassing Google’s security scans of Play applications to do so. Update: A Google spokesperson told Ars that the offending app has been suspended in the Play store. While the app was discovered installed on an infinitesimal percentage of devices checked by Check Point, it shows that the vulnerability caused by insecure OEM and cell carrier software meant to provide remote access to devices for customer service engineers has already been exploited by “legitimate” phone applications—and the method used to bypass Google’s security checks could be used for more malicious purposes on millions of devices. And there’s no easy way for Google or phone manufacturers alone to patch the problem." -- source: http://arstechnica.com/security/2015/08/major-android-remote-access-vulnera… 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/

Why Linux-Based Steam Machines Won’t Have A “Suspend” Function
by Lawrence D'Oliveiro 19 Aug '15

19 Aug '15

Current proprietary game consoles typically have a “sleep” mode, to allow faster startups than booting from a complete power-off. It turns out <http://arstechnica.com/gaming/2015/08/steam-machines-wont-have-a-suspend-fu…> that Valve’s Steam machines are unable to offer such a facility, for quite a subtle technical reason <http://games.slashdot.org/comments.pl?sid=7855261&cid=50329207>: it’s because, when the Linux kernel wakes up from sleep, it forgets about all the USB devices it saw before, and rediscovers them all as though for the first time. This prevents applications (i.e. games) from preserving the state of devices like game controllers.

Te Whare O Te ATA (Fairfield) computer lab
by Roderick Aldridge 11 Aug '15

11 Aug '15

Disappointing news about the computer lab in the annexe at Te Whare O Te Ata Fairfield/Chartwell Community House. The trustees have decided to use the annexe as a classroom. Manager Mike Rarere says the only practical option for the lab machines is for some of them (probably 6 or fewer) to be in the main lounge. The lounge schedule means that we could only have regular scheduled sessions on Monday and Friday mornings. Do you want to be involved in running this? It should be easier to do, although it is only a fraction of the former setup. Roderick Aldridge.

LibreOffice under the hood: progress to 5.0

08 Aug '15

"Today we release LibreOffice 5.0.0, a new foundation for ongoing work over the next months and years. It also has a fine suite of new features for people to enjoy - you can read and enjoy all the great news about the user visible features from so many great hackers, but there are, as always, many contributors whose work is primarily behind the scenes, and a lot of work that is more technical than user-facing. That work is, of course, still vitally important to the project." -- source: https://people.gnome.org/~michael/blog/2015-08-05-under-the-hood-5-0.html 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/

EFF Releases Privacy Badger an Addon That Algorithmically Blocks Online Trackers
by Peter Reutemann 07 Aug '15

07 Aug '15

"Online tracking has become a pervasive invisible reality of the modern web. Most sites you load are likely to be full of ads, tracking pixels, social media share buttons, and other invisible trackers all harvesting data about your web browsing. These trackers use cookies and other methods to read unique IDs associated with your browser, the result being that they record all the sites you visit as you browse around the internet. This sort of tracking is invisible to most web users, meaning they never get the option to agree to or opt-out of it. Today the EFF has launched the 1.0 version of Privacy Badger, an extension designed to prevent these trackers from accessing unique info about you and your browsing." -- source: http://yro.slashdot.org/story/15/08/07/0139241 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/

Bye-Bye 32 Bits?

The Fedora project <http://phoronix.com/scan.php?page=news_item&px=Fedora-i686-Non-Blocking> has noticed that very few of its users seem to be on 32-bit systems nowadays. This was shown by a kernel bug that went undetected for two months, that prevented 32-bit x86 systems from even booting. Time to relegate 32-bit machines to the junk pile?

New attack on Tor can deanonymize hidden services with surprising accuracy
by Peter Reutemann 03 Aug '15

03 Aug '15

"Computer scientists have devised an attack on the Tor privacy network that in certain cases allows them to deanonymize hidden service websites with 88 percent accuracy. Such hidden services allow people to host websites without end users or anyone else knowing the true IP address of the service. The deanonymization requires the adversary to control the Tor entry point for the computer hosting the hidden service. It also requires the attacker to have previously collected unique network characteristics that can serve as a fingerprint for that particular service. Tor officials say the requirements reduce the effectiveness of the attack. Still, the new research underscores the limits to anonymity on Tor, which journalists, activists, and criminals alike rely on to evade online surveillance and monitoring." -- source: http://arstechnica.com/security/2015/07/new-attack-on-tor-can-deanonymize-h… 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/

950 million Android phones can be hijacked by malicious text messages
by Peter Reutemann 27 Jul '15

27 Jul '15

'Almost all Android mobile devices available today are susceptible to hacks that can execute malicious code when they are sent a malformed text message or the user is lured to a malicious website, a security researcher reported Monday. The vulnerability affects about 950 million Android phones and tablets, according to Joshua Drake, vice president of platform research and exploitation at security firm Zimperium. It resides in "Stagefright," an Android code library that processes several widely used media formats. The most serious exploit scenario is the use of a specially modified text message using the multimedia message (MMS) format. All an attacker needs is the phone number of the vulnerable Android phone. From there, the malicious message will surreptitiously execute malicious code on the vulnerable device with no action required by the end user and no indication that anything is amiss.' -- source: http://arstechnica.com/security/2015/07/950-million-android-phones-can-be-h… 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/

SSH -> getting the originating IP of a client using RDP
by Eric Light 24 Jul '15

24 Jul '15

Hey all This is a total edge case, but I thought it may be interesting to some. We have thin clients, which RDP to a Windows Terminal Server, through which users SSH (using PuTTY) into our Linux server. This isn't flexible (for good reasons which I won't go into here). However, to talk properly to our new EFTPOS units, we need to know the IP of the thin client. Of course, through SSH you only get the IP of the client, which is the Terminal Server. Here's how I fixed it: 1) Add the following line to /etc/ssh/sshd_config, and restarted ssh: * AcceptEnv CLIENTNAME* 2) Added the following to the Windows login script: * REG ADD HKCU\Software\SimonTatham\PuTTY\Sessions\DG\ /v Environment /d "CLIENTNAME="%CLIENTNAME% /f* 3) Result: * ~ $ env | grep CLIENTNAME CLIENTNAME=eric-lmde* >From there, we can do what we needed with the EFTPOS!

Troubleshooting Over The Phone
by Lawrence D'Oliveiro 23 Jul '15

23 Jul '15

I just helped someone unbork their Ubuntu system over the phone. It was reporting “disk full”, without being more specific than that. I got him to open up a terminal window, and use the “df” and “du” commands to narrow down the directory that was filling up the disk. Sometimes /tmp gets filled up with stuff, but in this case it was /var/lib/apt/lists/partial/. I have had an instance of high disk usage on that directory myself, a while back. I think it’s where apt keeps partially-downloaded repo index files, though I’m not sure why—is it to retry downloading the rest? But when the problem hits, it just seems to fill up with failed downloads. So I carefully led him up to executing the command “sudo rm /var/lib/apt/lists/partial/*”, and that cleared the problem. The main thing I was careful with was spelling out the commands phonetically, and getting him to read them back to me. But imagine having to do this with a GUI, over the phone. I don’t think I would even try...

Why Debian Returned To FFmpeg
by Lawrence D'Oliveiro 23 Jul '15

23 Jul '15

<http://lwn.net/Articles/650816/> What impresses me about this is, even though the Debian package maintainer is also a libav developer, he “...in the end, could not bring himself to say that he was sure libav was the better choice.” With regard to the commit statistics, it seems like much of the activity in FFmpeg commits is wholesale copying of code from libav. But so what? If sticking with FFmpeg gives you the best of both worlds, why bother separately including packages for libav at all?

On Being Pro-GPL
by Peter Reutemann 22 Jul '15

22 Jul '15

'Christopher Allan Webber, recently returned from OSCON, shares his thoughts on the GPL and why he dislikes people pitting one type of software license against another. He says, "I am not only pro-copyleft, I am also pro-permissive licensing. The difference between these is tactics: the first tactic is towards guaranteeing user freedom, the second tactic is toward pushing adoption. I am generally pro-freedom, but sometimes pushing adoption is important, especially if you're pushing standards and the like. But let's step back for a moment. One thing that's true is that over the last many years we've seen an explosion of free and open source software... at the same time that computers have become more locked down than ever before! How can this be? And notice... the rise of the arguments for permissive/lax licensing have grown simultaneously with this trend. ...The fastest way to develop software which locks down users for maximum monetary extraction is to use free software as a base. And this is where the anti-copyleft argument comes in, because copyleft may effectively force an entity to give back at this stage... and they might not want to. ... Copyleft's strings say, 'you can use my stuff, as long as you give back what you make from it.' But the proprietary differentiation strategy's strings say, 'I will use your stuff, and then add terms which forbid you to ever share or modify the things I build on top of it.' Don't be fooled: both attach strings. But which strings are worse?"' -- source: http://news.slashdot.org/story/15/07/21/2256243 Personally, I'm a pro-GPL person. Simply because I don't like software getting locked down and nothing flowing back to the community. Especially, when open source is so community centred.

What the GNOME Desktop Gets Right and KDE Gets Wrong
by Peter Reutemann 14 Jul '15

'Eric Griffith at Phoronix has provided a fresh perspective on the KDE vs. GNOME desktop debate after exclusively using GNOME for the past week while being a longtime KDE user. He concluded his five-page editorial (which raises some valid points throughout) by saying, "Gnome feels like a product. It feels like a singular experience. When you use it, it feels like it is complete and that everything you need is at your fingertips. It feels like the Linux desktop. ... In KDE, it's just some random-looking window popup that any application could have created. ... KDE doesn't feel like cohesive experience. KDE doesn't feel like it has a direction its moving in, it doesn't feel like a full experience. KDE feels like its a bunch of pieces that are moving in a bunch of different directions, that just happen to have a shared toolkit beneath them." However, with the week over and despite his criticism, he's back to using KDE.' -- source: http://tech.slashdot.org/story/15/07/13/1548237 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/

Speed-Ups, Small Fixes Earn Good Marks From Ars For Mint 17.2
by Peter Reutemann 13 Jul '15

13 Jul '15

'Ars Technica reviews the newest release from Linux MInt -- version 17.2, offered with either the Cinnamon desktop, or the lighter-weight MATE, which feels like what Gnome 2 might feel in an alternate universe where Gnome 3 never happened. Reviewer Scott Gilbertson has mostly good things to say about either variety, and notes a few small drawbacks, too. The nits seem to be minor ones, though they might bite some people more than others: Mint, based on Ubuntu deep down, is almost perfectly compatible with Ubuntu packages, but not every one, and this newest version of Mint ships with the 3.16 kernel of Ubuntu 14.04, which means slightly less advanced hardware support. (Gilbertson notes, though, that going with 3.16 means Mint may be the ideal distro if you want to avoid systemd.) "This release sees the Cinnamon developers focusing on some of what are sometimes call "paper cut" fixes, which just means there's been a lot of attention to the details, particularly the small, but annoying problems. For example, this release adds a new panel applet called "inhibit" which temporarily bans all notifications. It also turns off screen locking and stops any auto dimming you have set up, making it a great tool for when you want to watch a video or play a game." More "paper cut" fixes include improved multi-panel options, graphics-refresh tweaks, a way to restart the Cinnamon desktop without killing the contents of a session, graphics-refresh tweaks, and other speed-ups that make this release "noticeably snappier than its predecessor on the same hardware."' -- source: http://linux.slashdot.org/story/15/07/12/1720236 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/

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”.

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

'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.

So How Did Your Leap-Second Go?
by Lawrence D'Oliveiro 01 Jul '15

At noon today NZ time, an extra second was inserted into UTC, the time kept by the world’s atomic clocks. The time that was one second before midnight UTC (one second before noon NZST) became two seconds before intead: after 23:59:59 UTC came 23:59:60 UTC, before ticking over to 0:00:00 UTC. The previous time this happened, three years ago, several Linux-based systems malfunctioned. No word yet on how this one went... <http://lwn.net/Articles/648313/>

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.

F2FS Brings Per-File Encryption With Linux 4.2
by Peter Reutemann 25 Jun '15

"Based on the native encryption support added to EXT4 with the Linux 4.1 kernel, Linux 4.2 is bringing encryption support to the F2FS file-system. F2FS has been working on native encryption support in tandem with the EXT4 work and now it's been called for merging today into Linux 4.2. Jaegeuk Kim sent in the F2FS feature update for Linux 4.2 and it features per-file encryption support along with new capabilities for FALLOC_FL_ZERO_RANGE (converting a range of file to zeroes), FALLOC_FL_COLLAPSE_RANGE (removes a byte range from a file), and RENAME_WHITEOUT. The Flash-Friendly File-System for Linux 4.2 also has recovery for broken super-blocks, TRIM improvements, and various fixes.

Got Chrome? Google Just Silently Downloaded This Onto Your Computer

'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.

The website Private Internet Access‘s Rick Falkvinge reported how he came to understand this new policy: “It looked like just another bug report. “When I start Chromium, it downloads something.” Followed by strange status information that notably included the lines “Microphone: Yes” and “Audio Capture Allowed: Yes”.

City libraries have titles in the Dummies series about the Raspberry Pi and BeagleBone. Much of the material is directed at providing information on Linux for beginners, covering much the same ground in both titles. There is also a primer on Python programming. Perhaps the most interesting information deals with hardware aspects of interfacing with the boards including several small projects. In related news the latest Distrowatch Weekly has an article on using a Raspberry Pi as a server for backups in a home network.

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."”

This can be exploited by an unprivileged process in kernels with CONFIG_USER_NS=y and where overlayfs has the FS_USERNS_MOUNT flag, which allows the mounting of overlayfs inside unprivileged mount namespaces. This is the default configuration of Ubuntu 12.04, 14.04, 14.10, and 15.04 [1]." This could be something requiring a bit of attention. Heads-up.

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/

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.

“*ERROR* pipe is still busy with an old pageflip”
by Lawrence D'Oliveiro 24 May '15

24 May '15

I’ve been hitting an occasional display freeze that matches this description <http://forums.gentoo.org/viewtopic-p-7675146.html>. Looks like a known problem with the 3.16 kernel. I thought things had got better with a system update I did 11 days ago, but this afternoon the freeze recurred. Unlike the previous times, killing all my user processes succeeded in unfreezing the display, so I was able to log in again without rebooting.

'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/

Linux 4.0 Has a File-System Corruption Problem, RAID Users Warned

'For the past few days kernel developers and Linux users have been investigating an EXT4 file-system corruption issue affecting the latest stable kernel series (Linux 4.0) and the current development code (Linux 4.1). It turns out that Linux users running the EXT4 file-system on a RAID0 configuration can easily destroy their file-system with this newest "stable" kernel. 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

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/>

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.

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?

NVIDIA’s New Hardware Becoming “Open-Source-Unfriendly”
by Lawrence D'Oliveiro 16 Apr '15

16 Apr '15

NVIDIA, in its desire to stop third parties making hacks to its firmware to enable higher-end features on lower-end hardware, is moving to requiring signed firmware on its newer cards. Some promises made to the Nouveau project (which is developing open-source drivers for NVIDIA cards) have yet to eventuate, leaving them unable to take advantage of features of these cards. <http://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-Unfriendly-OSS-Ha…>

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>

reading files from old applications
by Ian Young 15 Apr '15

When all else fails try strings :-) Man strings. The resulting output if any could need a bit of tidying up.I have tried this on the odd older MS Word file when there was no alternative, at least gives an idea of text content. Hmmm. Having said that, I see the fine manual says ' strings is mainly useful for determining the contents of non-text files.'

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/>

Linux 4.0 released
by Peter Reutemann 13 Apr '15

"So I decided to release 4.0 as per the normal schedule, because there really weren't any known issues, and while I'll be traveling during the end of the upcoming week due to a college visit, I'm hoping that won't affect the merge window very much. 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. But we've definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones)." -- source: http://www.linuxtoday.com/developer/linux-4.0-released.html Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

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

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?

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…>.

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.

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.

Xfce 4.12 Released
by Peter Reutemann 01 Mar '15

01 Mar '15

"After two years of hard work (and much to the dismay of naysayers who worried the project has been abandoned), the Xfce team has announced the release of Xfce 4.12. Highlights include improvements to the window switcher dialog, intelligent hiding of the panel, new wallpaper settings, better multi-monitor support, improved power settings, additions to the file manager, and a revamped task manager. Here is a quick tour, the full changelog, and the download page. I have been running it since Xubuntu 15.04 beta 1 was released two days ago. It is much improved over 4.10, and the new additions are great." -- source: http://linux.slashdot.org/story/15/03/01/0558259 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

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>.

Linus Torvalds Debuts First Linux 4 Release Candidate

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

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/

Arduino Ructions

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.

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."

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

"ownCloud <https://owncloud.org/>, a free software alternative to proprietary web services such as Dropbox, Google Drive and others that you can install on your own server, has reached version 8.0.0." "http://www.webupd8.org/2015/02/owncloud-8-server-released-with.html" I Have been running v7 on Fedora 21 Server for about 8 weeks works great, this is a really nice solution if you are looking at running your own cloud and don't want to dive into openstack.
