A ZFS developer’s analysis of the good and bad in Apple’s new APFS file system
by Peter Reutemann 28 Jun '16

28 Jun '16

"Adam Leventhal: Apple announced a new file system that will make its way into all of its OS variants (macOS, tvOS, iOS, watchOS) in the coming years. Media coverage to this point has been mostly breathless elongations of Apple's developer documentation. With a dearth of detail I decided to attend the presentation and Q&A with the APFS team at WWDC. Dominic Giampaolo and Eric Tamura, two members of the APFS team, gave an overview to a packed room; along with other members of the team, they patiently answered questions later in the day. With those data points and some first-hand usage I wanted to provide an overview and analysis both as a user of Apple-ecosystem products and as a long-time operating system and file system developer." -- source: http://arstechnica.com/apple/2016/06/a-zfs-developers-analysis-of-the-good-… 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/

Ubuntu-Based Peppermint 7 Released
by Peter Reutemann 26 Jun '16

26 Jun '16

'Softpedia reports on the newest version of Peppermint OS, "a lightweight, stable, elegant, and fast computer operating system based on GNU/Linux and Open Source technologies." An anonymous Slashdot reader quotes their report: It's a bit earlier than expected, but the Peppermint OS 7 GNU/Linux distribution has been officially unveiled...based on the Ubuntu 16.04 LTS (Xenial Xerus) operating system [with] a lot of packages from the Ubuntu 16.04 LTS distro, which means that it will also be a long-term support release.... "Along with the shift to the 16.04 (Xenial) code base, Peppermint 7 continues our policy of choosing the best components from other desktop environments, wherever that may be, and integrating them into a cohesive whole with our own software," reads today's announcement. "Team Peppermint" says they're switching to Firefox as their default browser for site-specific browser functionality (similar to Chrome's -app mode) after Google dropped their 32-bit version of Chrome and moved to PPAPI plugins "which effectively ends Flash support in 32-bit Chromium"... But you can also still choose Chrome or Chromium for site-specific browsing (and the OS comes in 32-bit and 64-bit editions).' -- source: https://news.slashdot.org/story/16/06/25/216216 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/

KDE Developers Have Been Working On Improved Windows Support
by Lawrence D'Oliveiro 22 Jun '16

22 Jun '16

<http://phoronix.com/scan.php?page=news_item&px=KDE-Windows-Improvements>: “... they've abandoned the concept of having a single KDE installer for Windows, but work on individual programs (and installers) for Windows has continued. Single application installers are their path forward for shipping KDE programs on Windows...” Also in the reader comments, Krita lead Boudewijn Rempt writes about whether more Windows users leads to more Windows developers contributing <https://www.phoronix.com/forums/forum/software/desktop-linux/879128-kde-dev…>: “... I've certainly had half a dozen Windows developers come to the #krita irc channel asking how to build Krita on Windows so they could help out hacking. The problem is that setting up a build environment on WIndows is really hard, and in fact, we build the Windows binaries on Linux... So they need extraordinary perseverance to start contributing or use a Linux VM. That's really something we should improve on next, but I have no idea how to make it any eas[i]er anymore.”

WLUG meeting next Monday
by Peter Reutemann 22 Jun '16

22 Jun '16

Hi there We have a meeting next Monday: 'systemd', which has replaced SYSTEMV 'init' in nearly ALL current Linux distributions, seems to go against the fundamental philosophy of Linux/Unix - Doug Mcllroy, the inventor of Unix pipes, summarized the Unix/Linux philosophy as follows: "This is the Unix philosophy: Write programs that do one thing and do it well..." systemd has a 'finger-in-all-pies' approach & seems quite complex. Let's discuss pros and cons of systemd. http://www.meetup.com/WaikatoLinuxUsersGroup/events/231330392/ 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/

Linux’s RPM/deb split could be replaced by Flatpak vs. snap
by Peter Reutemann 21 Jun '16

21 Jun '16

'Linux developers are going to have more than one choice for building secure, cross-distribution applications. Ubuntu's "snap" applications recently went cross-platform, having been ported to other Linux distros including Debian, Arch, Fedora, and Gentoo. The goal is to simplify packaging of applications. Instead of building a deb package for Ubuntu and an RPM for Fedora, a developer could package the application as a snap and have it installed on just about any Linux distribution. But Linux is always about choice, and snap isn't the only contender to replace traditional packaging systems. Today, the developers of Flatpak (previously called xdg-app) announced general availability for several major Linux distributions, with a pointer to instructions for installing on Arch, Debian, Fedora, Mageia, and Ubuntu.' -- source: http://arstechnica.com/information-technology/2016/06/here-comes-flatpak-a-… 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/

Microsoft: Nearly One In Three Azure Virtual Machines Now Are Running Linux
by Peter Reutemann 21 Jun '16

21 Jun '16

"Microsoft's self-professed Linux love is helping the company in the cloud. During his keynote at DockerCon 2016 in Seattle today, Azure Chief Technology Officer Mark Russinovich showed off some of the new and upcoming ways Microsoft is adding more container support to its cloud and server products. He also revealed a couple of new interesting datapoints. In the past year, Russinovich said, Microsoft has gone from one in four of its Azure virtual machines running Linux to nearly one in three. The other two-thirds of Azure customers are running Windows Server in their virtual machines. Russinovich showed off the promised Windows Server support that officials said would be coming at some point to the company's Azure Container Service (ACS). Microsoft made Azure Container Service generally available in April 2016, but for Linux containers only. Last year, company execs said Microsoft also would bring Windows Server support to ACS." -- source: https://linux.slashdot.org/story/16/06/21/1754243 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/

New World’s Fastest: 10-Million Core Supercomputer
by Lawrence D'Oliveiro 21 Jun '16

21 Jun '16

<http://arstechnica.com/information-technology/2016/06/10-million-core-super…> Not Intel-compatible, uses a home-grown 64-bit RISC chip architecture. According to this <http://www.nextplatform.com/2016/06/20/look-inside-chinas-chart-topping-new…>, it achieves 3 times the power efficiency of the x86 machines near the current top of the supercomputing league. According to the Ars article, the previous supercomputer king of the hill, “Tianhe-2 had been the world's fastest in six consecutive rankings, which are released twice a year”. So I think the record for staying the longest at the top still remains with the old NEC Earth Simulator, which was number one for maybe two years.

New 'Hardened' Tor Browser Protects Users From FBI Hacking
by Peter Reutemann 20 Jun '16

20 Jun '16

'According to a new paper, security researchers are now working closely with the Tor Project to create a "hardened" version of the Tor Browser, implementing new anti-hacking techniques which could dramatically improve the anonymity of users and further frustrate the efforts of law enforcement... "Our solution significantly improves security over standard address space layout randomization (ASLR) techniques currently used by Firefox and other mainstream browsers," the researchers write in their paper, whose findings will be presented in July at the Privacy Enhancing Technologies Symposium in Darmstadt, Germany. The researchers say Tor is currently field-testing their solution for an upcoming "hardened" release, making it harder for agencies like the FBI to crack the browser's security, according to Motherboard. "[W]hile that defensive advantage may not last for too long, it shows that some in the academic research community are still intent on patching the holes that their peers are helping government hackers exploit."' -- source: https://yro.slashdot.org/story/16/06/19/2249239 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/

Fedora QA Lead Pans Canonical 'Propaganda' On Snap Apps
by Peter Reutemann 18 Jun '16

18 Jun '16

'...and how it's going to unite all distributions and kill apt and rpm! This is, to put it diplomatically, a heaping pile of steaming bullshit... The press release and the stories together give you the strong impression that this thing called Snappy is going to be the cross-distribution future of application delivery, and it's all ready for use today and lots of major distributions are buying into it... The stories have headlines like "Adios apt and yum? Ubuntu's snap apps are coming to distros everywhere" and "Snap Packages Become Universal Binary Format for All GNU/Linux Distributions"... Now, does Snappy actually have the cross-distribution buy-in that the press release claims (but never outright states) that it has? No... The sum total of communication between Canonical and Fedora before the release of this press release was that they mailed us asking about the process of packaging snappy for Fedora, and we told them about the main packaging process and COPR. They certainly did not in any way inform Fedora that they were going to send out a press release strongly implying that Fedora, along with every other distro in the world, was now a happy traveler on the Snappy bandwagon... They just decided to send out a wildly misleading press release and actively encourage the specialist press to report that Snappy was all set to take over the world and everyone was super happy with that.' -- source: https://linux.slashdot.org/story/16/06/18/1550249 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/

'The biggest manufacturer of the Raspberry Pi minicomputer, Premier Farnell, has been acquired by Swiss industrial component supplier Daetwyler Holding AG for roughly $871 million. According to Bloomberg, the deal will reportedly help both companies compete better in the components market. "By combining forces, we significantly increase our competitiveness and extend our product range," Daetwyler Chairman Ulrich said in a statement, "facilitating a one-stop shopping experience for our wide range of customers from a multitude of industries." Premier Farnell is one of the only companies with a license to design and distribute Raspberry Pis. The Wall Street Journal says the Raspberry Pi devices are a big part of the company's business, as the division in charge of the Pi raked in 16 percent of the company's total revenue last year.' -- source: https://news.slashdot.org/story/16/06/14/2044241 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/

Thousands of Email Addresses Accidentally Disclosed By Let's Encrypt Anonymous
by Peter Reutemann 12 Jun '16

12 Jun '16

'"Let's Encrypt, the certificate authority best known for offering free SSL/TLS certificates, has reported that it accidentally disclosed thousands of user email addresses due to a bug with an automated emailing system." Executive Director Josh Aas posted this announcement: On June 11 2016 (UTC), we started sending an email to all active subscribers who provided an email address, informing them of an update to our subscriber agreement. This was done via an automated system which contained a bug that mistakenly prepended between 0 and 7,618 other email addresses to the body of the email... The problem was noticed and the system was stopped after 7,618 out of approximately 383,000 emails (1.9%) were sent. Each email mistakenly contained the email addresses from the emails sent prior to it, so earlier emails contained fewer addresses than later ones. We take our relationship with our users very seriously and apologize for the error... If you received one of these emails we ask that you not post lists of email addresses publicly.' -- source: http://m.slashdot.org/story/312355 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

Firefox Finally Confirms 'Largest Change Ever' Featuring Electrolysis In v48
by Peter Reutemann 09 Jun '16

09 Jun '16

'With Electrolysis, Firefox can use child processes for content (tabs), media playback and legacy plug-ins. This is some way short of Google Chrome, which uses a different process for each tab. However, the result is that Chrome is a huge resource hog: Chrome uses roughly twice as much memory as Firefox on Windows and Linux. Eric Rahm has run some browser tests with Electrolysis, and says: "Overall we see a 10-20 percent increase in memory usage for the 1 content process case (which is what we plan on shipping initially). This seems like a fair trade-off for potential security and performance benefits." With 8 content processes, Rahm says: "we see roughly a doubling of memory usage on the TabsOpenSettled measurement. It's a bit worse on Windows, a bit better on OS X, but it's not 8 times worse."' -- source: https://news.slashdot.org/story/16/06/08/1635231 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/

The Web's Creator Thinks We Need a New One That Governments Can't Control

'The web has created millions of jobs, impacted nearly every industry, connected people, and arguably made the world a better place. But the person who started it all isn't exactly pleased with the way things have turned out to be. Sir Tim Berners-Lee, who invented the World Wide Web, believes that the way it works in the present day "completely undermines the spirit of helping people create." The Next Web reports: "Edward Snowden showed we've inadvertently built the world's largest surveillance network with the web," said Brewster Kahle, who heads up Internet Archive. And he's not wrong: governments across the globe keep an eye on what their citizens are accessing online and some censor content on the Web in an effort to control what they think. To that end, Berners-Lee, Kahle and other pioneers of the modern Web are brainstorming ideas for a new kind of information network that can't be controlled by governments or powered by megacorporations like Amazon and Google.' -- source: https://tech.slashdot.org/story/16/06/08/196225 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/

Re: [wlug] TRIMMING POSTS -- PLEASE ???!!!
by Eric Light 07 Jun '16

07 Jun '16

(Michelle you sent this to me directly, but I believe you intended to send it to the whole mailing list, so I'll include that here. I've left the history included, in spite of Ian's entreaties otherwise, for the benefit of those who want to see what I'm replying to) Ah, I understand a bit better now. By and large, Linux is relatively untouched by garden variety malware. However, your browser (cross-platform, JavaScripty, etc) can still fall prey to security issues, which sounds the case here. I note you said you were running NoScript, so it comes as a surprise, but I suppose they're always thinking up new avenues. That said, I don't think the Oprah thing is related to your missing files! I can't say what happened, but its vanishingly unlikely that a browser hijack could have deleted files on a LINUX system... On Windows, sure, but to perform that action on a Linux pc, the malware would need to be designed FOR Linux - and that's particularly unlikely. Okay so we've established that you want privacy, but overall you want a system where you can easily recover from corruption... Is that correct? I'm sticking with my recommendation for Debian - probably Linux Mint Debian Edition, because it's:- got a solid base (Debian) - got a wide user base (thus lots of testing) - got a lovely UI (Cinnamon) - specifically designed to be easy to use On top of this, you can install Sophos Antivirus for Linux... It's free, and it has some of the highest detection rates in the industry (note, solving a problem that barely even exists in a Linux environment, but which you may have encountered nonetheless). Since your threat profile sounds like browser-based malware, it might be worth looking into specifically sandboxing your browser. I know Chrome already does sandboxing between tabs and threads, so that might already be in place, but it sounds plausible. Alternatively, putting your /home partition on a filesystem that supports snapshots might be a good idea... Maybe ZFS? That sounds like a good solution to me, but I'll have to defer to the wizards in the group. ☺ Good luck!Eric -- Securely sent with Tutanota. It's good, you should try it: https://tutanota.com 7.

TRIMMING POSTS -- PLEASE ???!!!
by Ian Young 07 Jun '16

07 Jun '16

The saga of 'Michelle' (iirc) and her Linux problems is no doubt fascinating but could we possibly stop wasting bandwidth by broadcasting the entire sorry saga time and time again ... just asking. Aside from any other considerations it makes it difficult to determine whether there is any new data on the case. Far be it from me to speculate on whether the poster is just a wee bit batty .....

I can pay 150 if somone is willing to help me out with setting up a computer
by Michelle 05 Jun '16

05 Jun '16

Hi, My name's Michelle. I've been using Linux on and off for the last few years. I'm looking for someone who would help me set up a computer with linux on it. I rang round all? or most the PB tech stores, they didn't have anyone who was up to the task. I rang a store where a guy was into Linux but they're too busy. I sent an email to a guy involved with one of the distros I want but even though it's on the web to contact him to pay for help he hasn't got back to me. A man kindly pointed out to me two computers from PB tech that he says will work but as you can see from the post I've had some trouble with computers not working or not working properly and I want to pay some money for someone to try the distros and experience that it works on a computer for sure. I had a Dell on which I set up Puppy with no problem whatsoever. The computer died and so then I took the puppy distro and the other disto I'd bought (can't remember what) and tried to install them on 2 older computers I had but it didn't work. I don't know why, maybe it was because one of the distros was on a USB drive and not compatible or maybe both computer hard drives were stuffed? After that I bought a mini-pc (I think it was supposed to run linux) but it didn't work at all. Then I bought a tablet but after a month or two it stopped working or pretty much? Stopped working. So I just used a phone for about a year and last year bought a brand new Toshiba laptop. The problem with this was two fold: 1. It was a laptop. 2. It was a Toshiba (oh how I hate Toshiba) I had known that not all computers were readily compatible with linux but after my easy experience with the Dell I wasn't too concerned. I bought two linux distros on different media and hoped/assumed? that something would work – it didn't. I bought another say 2 or 3 distros and managed to get the Mint to install on this Toshiba. It wasn't until after this annoying endeavor that I found out online that: -⁠ laptops are less compatible than desktops with linux and that - Toshiba out of the maybe top 6 or 8 computer manufacturers is consistantly about the least compatible with linux ( I HATE TOSHIBA) I don't happen to have a few spear thousand dollars sitting around to enable me to buy a computer and try and set it up with the distros I want, find it dosen't work, buy another computer, find it doesn't work, buy another and finally find one that works with the distros I want. So I am sending this message and hoping someone can help me set up a computer with the two linux distros I want. I don't know how that would work. Maybe someone is about to buy a new computer and can try these distros before they put theirs on, maybe someone has a partition on their computer that is spare and can try it there, maybe they own a computer shop or work in a computer shop or at a university or polytech with computers or computer parts around. So for anyone who may be willing to help me here is what I would like: - I'm up for paying up to 700 but would prefer to just pay say 400 or 500. - a desktop (not the modern ones that are a computer plus other thing/s but just a computer -⁠ not a toshiba -⁠ Whonix to run on top of Qubes. Whonix is great for anonimity and Qubes is designed for security/⁠safety. - I have a DrayTek vigor 120 modem. I connect it via DSL. When looking into whonix I read that it is complex to configure and setup, so I was hoping that you might have such a modem or access to one and set it up with whonix and then tell me how you did it. - I don't want the computer to come with wifi or bluetooth or any similar thing. I don't want it just not running, I don't want it there at all. - I'm wanting to install 3 old encyclopedias. I was reading about the new versions online and people were recommending old ones. I've bought Encarta 2004, 2001 and Encyclopaedia Britannica '98. To run them on I've bought Windows 98 second edition and Windows NT (first edition?). If you have or could borrow these windows OS could you see if you could get them running in whonix or qubes? - One or both of the encyclopedias need 2 DVD players so I'd like at least 2 DVD players with one being a recorder. - I'm not looking for a high end computer. As long as it will play youtube, that's fast enough. BUT I would appreciate hearing any recommendation about if I just add such and such for $100 or $150 it would go much faster. I'd like 500GB hard drive at least and I've been recommended to get 8GB RAM at least. I wouldn't buy the computer off you but rather if you could tell me what computer/computer parts worked, I'd pay up to $150 for the info. If 10 different people told me what worked of course I couldn't pay 10 different people $150. So to prevent two or more different people working on it at the same time, if you are willing to help me out could you please let me know and I could post a message just asking that no one else start working on it. It would be nice to have a choice of say two or three computers. So perhaps someone could say there is this computer or that one and I could ask you to try installing Whonix and Qubes on one of them. Or maybe there was a choice of two computers in parts and I could be told the parts of one computer and the other and I could choose the parts for one. It doesn't have to be brand new. As long as I can still buy it or the parts new it could be up to two years old. Thank you to anyone willing to help Michelle Gorringe.

Op-ed: Oracle attorney says Google’s court victory might kill the GPL
by Peter Reutemann 03 Jun '16

03 Jun '16

"The developer community may be celebrating today what it perceives as a victory in Oracle v. Google. Google won a verdict that an unauthorized, commercial, competitive, harmful use of software in billions of products is fair use. No copyright expert would have ever predicted such a use would be considered fair. Before celebrating, developers should take a closer look. Not only will creators everywhere suffer from this decision if it remains intact, but the free software movement itself now faces substantial jeopardy." -- source: http://arstechnica.com/tech-policy/2016/05/op-ed-oracle-attorney-says-googl… Interesting article, I have to say. The verdict might throw a spanner in what is considered "derivative work" in terms of GPL code. Companies using GPL libraries will no longer have to open-source their code, as it is simple considered fair use?

Linux Kernel 4.6.1 Released; Some Users Report Boot Issue
by Peter Reutemann 02 Jun '16

02 Jun '16

'Linux kernel 4.6.1 is already here, only two weeks after the official launch of the Linux 4.6 kernel series. For those not in the loop, Linux 4.6 branch is the latest and most advanced kernel branch available right now for GNU/Linux operating systems, but it looks like its adoption is a little slow at the moment. "I'm announcing the release of the 4.6.1 kernel. All users of the 4.6 kernel series must upgrade," says Greg Kroah-Hartman. "The updated 4.6.y git tree can be browsed at the normal kernel.org git web browser."' 'Several folks on the web have reported a regression in the latest Linux kernels, starting with 4.6.1 and including the 4.7 beta that prevents booting and drops to busybox, at least the one supplied by the Ubuntu PPA. The boot sequence ends with "address family not supported by protocol: error getting socket" and then, "error initializing udev control socket" (screenshot here).' -- source: https://linux.slashdot.org/story/16/06/02/1717235 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/

BBC Micro:Bit Learn-To-Code Device Up For Public Pre-Order In UK
by Peter Reutemann 02 Jun '16

02 Jun '16

'A tiny programmable board designed as part of an educational initiative for UK kids to learn programming skills and originally distributed by the public service broadcaster, the BBC, to one million schoolchildren is now up for public pre-order. The micro:bit is available for public pre-order in the UK, via Element14's website, with delivery slated for July. Although at this point it's being sold in minimum quantities of 90 for resellers (such as Microsoft) to then sell on to individuals. So consumers will have a bit longer to wait to be able to buy a device just for themselves. Prices start at 12.99 Pound ($19) for a single BBC micro:bit; 14.99 Pound for a starter kit which includes a BBC micro:bit, mini USB, battery pack and four project ideas; and 140 Pound for a 'BBC micro:bit Club' pack, which includes 10 devices and "everything needed to get a coding club started". The intention with the micro:bit project -- part of the BBC's wider 'Make it Digital' initiative to inspire "a new generation to get creative with coding, programming and digital technology" -- was always to open up the distribution of the device after the initial giveaway.' -- source: https://hardware.slashdot.org/story/16/06/01/1548252 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/

Tor Browser 6.0: Ditches SHA-1 Support, Uses DuckDuckGo For Default Search Results
by Peter Reutemann 01 Jun '16

01 Jun '16

"The version 6.0 of Tor Browser, a free software for enabling anonymous communication, is now available to download. The new version introduces several changes, including disabling SHA-1 support, and removing Mac Gatekeeper issue. Another big change is that Tor now uses DuckDuckGo for search results by default. The Tor Project, people behind Tor, add that the "updater is not relying on the signature alone, but is checking the hash of the downloaded update file as well before applying it."

Issue with systemd
by Ian Young 30 May '16

30 May '16

>From this week's Distrowatch. Could be a problem in some circumstances. The systemd project tends to stir up debate with each new feature it implements. One of the most recent changes to systemd (available in version 230), forces user processes to terminate when the user logs out. On some systems, such behaviour makes sense and effectively cleans up misbehaving processes when the user leaves. However, many administrators and developers rely on processes continuing to run to perform tests, backups or other tasks after they log off. Guus Sliepen summed up the concerns of the latter group quite nicely in a Debian bug report: It is now indeed the case that any background processes that were still running are killed automatically when the user logs out of a session, whether it was a desktop session, a VT session, or when you SSHed into a machine. Now you can no longer expect a long running background processes to continue after logging out. I believe this breaks the expectations of many users. For example, you can no longer start a screen or tmux session, log out, and expect to come back to it. For this reason, I think it is a bad decision on the part of the systemd maintainers to enable this feature by default, and it should rather be disabled by default in Debian." A similar discussion is taking place on a Fedora mailing list. The new default systemd behaviour can be disabled (either by distributions or system administrators) by editing the logind configuration file.

Yes, it breaks the well established practice that the controlling terminal sends all its child processes a HUP signal on logout, and that the default signal handler will kill such processes, and if the process wants to remain running it therefore establishes a signal handler to properly receive and handle the HUP signal so that it is not terminated. If processes are not being terminated on logout when they should be, then it is the non-terminating processes fault as the process has taken action to set up a non-default signal hangler to receive the HUP signal to achieve this effect. It is most certainly not the responsibility of systemd to kill processes on logout! With these critical and non-sensical changes to system behaviour that is well without the established remit of the init process the systemd developers are fast losing what little respect I might have had for them. Cheers Michael. _______________________________________________ wlug mailing list | wlug(a)list.waikato.ac.nz Unsubscribe: https://list.waikato.ac.nz/mailman/listinfo/wlug

Whom to contact for a public mirror for a Linux distribution?
by Michael Doerner - Technologywise 26 May '16

26 May '16

Hi all I am involved with a Linux distribution called "Koozali SME server" (https://wiki.contribs.org/Main_Page) Unfortunately we lost our mirror in NZ (Oceania) due to very sad circumstances and I am looking whether there is a chance to add that distro to one of the existing public mirrors. I am following the Wiki http://wiki.wlug.org.nz/NewZealandLinuxMirrors and would like to ask at University of Canterbury (Hm, there is a directory on their mirror server called "contrib" and I wonder whether there was something planned at some time ago). If someone here knows how to get in contact (email?) with an admin person there, I would appreciate any hint. Thanks Michael Doerner

Cheers, Peter ---------- Forwarded message ---------- This Meetup will be announced to the group if 3 people say they're going. Or you can announce it now. Bruce Gilbert suggested a new Meetup. What: Talk about Linux/Unix philosophy & 'systemd'. When: This Meetup needs a date Where: This Meetup needs a location 'systemd', which has replaced SYSTEMV 'init' in nearly ALL current Linux distributions, seems to go against the fundamental philosophy of Linux/Unix. It has a 'finger-in-all-pies' approach & is, I believe, unnecessarily complex? Click here to check out this Meetup: http://www.meetup.com/WaikatoLinuxUsersGroup/events/231330392/

Raspberry Pi Zero gains camera support, keeps the $5 price

"When the Raspberry Pi Foundation launched the credit-card sized Zero, it stressed that the DIY computing board would not be as capable as the rest of the Pi family.

Today, the Zero has received its first major hardware upgrade since its hugely successful launch in November: a camera connector.

Open-Source VPU-Side Bootloader For Raspberry π
by Lawrence D'Oliveiro 17 May '16

17 May '16

The Raspberry π has been open-source from the beginning in every respect except one: the earliest stages of booting are actually managed by the “VPU” graphics chip, not by the ARM CPU. And the bootloader has been a proprietary firmware blob with no source code available. What made it worse was that the VPU has control over the CPU, not the other way round. Now it looks like that may be changing <http://phoronix.com/scan.php?page=news_item&px=Raspberry-Pi-Bootloader>.

Ubuntu 16.04 proves even an LTS release can live at Linux’s bleeding edge
by Peter Reutemann 16 May '16

16 May '16

'A disappointing trend has become clear to Linux users in recent years. Whenever Canonical offers a new Ubuntu Long Term Support (LTS) release, it tends to be conservative in nature. (See our Ubuntu 14.04 review, which earned a "Missing the boat on big changes" headline.) Apparently no one wants to try to support a brand new, potentially buggy piece of code for half a decade. The last few Ubuntu releases haven't been LTS rollouts, yet Vivid Vervet (15.04) and Wily Werewolf (15.10) also short-changed users in the way of new features. So when Canonical officially released the latest Ubuntu LTS version (Ubuntu 16.04 or Xenial Xerus) this spring, similar expectations loomed. Frankly, this could potentially be the most boring Ubuntu release to date. Thankfully, perception hasn't matched reality this time around for Ubuntu users. Ubuntu 16.04 is in fact the most exciting release Canonical has put out in recent memory. And after using it for the last few weeks, this may even be the best release Canonical has presented to date.' -- source: http://arstechnica.com/information-technology/2016/05/ubuntu-16-04-proves-e… 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/

So for anyone who may be willing to help me here is what I would like: - a desktop (not the modern ones that are a computer plus other thing/s but just a computer - not a toshiba - Whonix to run on top of Qubes. Whonix is great for anonimity and Qubes is designed for security/safety. - I have a DrayTek vigor 120 modem. I connect it via DSL. When looking into whonix I read that it is complex to configure and setup, so I was hoping that you might have such a modem or access to one and set it up with whonix and then tell me how you did it. - I don't want the computer to come with wifi or bluetooth or any similar thing. I don't want it just not running, I don't want it there at all. - I'm wanting to install 3 old encyclopedias. I was reading about the new versions online and people were recommending old ones. I've bought Encarta 2004, 2001 and Encyclopaedia Britannica '98. To run them on I've bought Windows 98 second edition and Windows NT (first edition?). If you have or could borrow these windows OS could you see if you could get them running in whonix or qubes? - One or both of the encyclopedias need 2 DVD players so I'd like at least 2 DVD players with one being a recorder. - I'm not looking for a high end computer. As long as it will play youtube, that's fast enough. BUT I would appreciate hearing any recommendation about if I just add such and such for $100 or $150 it would go much faster. I'd like 500GB hard drive at least and I've been recommended to get 8GB RAM at least. I wouldn't buy the computer off you but rather if you could tell me what computer/computer parts worked, I'd pay up to $150 for the info. If 10 different people told me what worked of course I couldn't pay 10 different people $150. I am sending this to: the wlug, Glen Ogilvie at nelg(a)linuxsolutions.co.nz in Auckland, the Welly LUG through hugh(a)davenport.net.nz, nzlug(a)lists.nzoss.org.nz and Wellington LUG through jethro.carr(a)jethrocarr.com. If you know of any active LUG that I have missed or anyone else that might be willing to assist me could you please pass this onto them? My email is michelle400(a)orcon.net.nz. If this is posted to a mailing list (I've never used one before) and I don't reply in a week could you get back to me on my email? Thank you to anyone willing to help Michelle Gorringe.

BitKeeper Becomes Open-Source
by Lawrence D'Oliveiro 10 May '16

10 May '16

BitKeeper was the distributed version-control system that Linus Torvalds and the other kernel developers were using over a decade ago. It was a proprietary product, but the Linux folk were allowed use of it for no charge, under a licence that prohibited reverse-engineering, and that obligated them to uprade to newer versions with whatever new licence terms the company wanted to impose. It was a stoush over this reverse-engineering prohibition that led to BitMover giving notice it was cancelling this agreement, which in turn led to Torvalds creating Git. And the rest, as they say, is history. <http://phoronix.com/scan.php?page=news_item&px=BitKeeper-Open-Source>

Debian Dropping Support For Older CPUs
by Peter Reutemann 09 May '16

09 May '16

'The Debian project supports a wide range of hardware architectures, including 32-bit x86 CPUs. Changes are happening in Debian's development branches which will make older versions of the 32-bit architecture obsolete. Ben Hutchings provides the details: "Last year it was decided to increase the minimum CPU features for the i386 architecture to 686-class in the Stretch release cycle. This means dropping support for 586-class and hybrid 586/686 processors. (Support for 486-class processors was dropped, somewhat accidentally, in Squeeze.) This was implemented in the Linux kernel packages starting with Linux 4.3, which was uploaded to Unstable in December last year. In case you missed that change, GCC for i386 has recently been changed to target 686-class processors and is generating code that will crash on other processors. Any such systems still running Testing or Unstable will need to be switched to run Stable (Jessie)."' -- source: https://linux.slashdot.org/story/16/05/09/028259 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/

Leading-Edge Technology ... Or Not
by Lawrence D'Oliveiro 07 May '16

To service the McLaren F1 supercar, McLaren needs a Compaq LTE 5280 laptop which hasn’t been manufactured in about 20 years <http://www.theverge.com/2016/5/3/11576032/mclaren-f1-compaq-laptop-maintena…>. The laptop has a special CA (“Conditional-Access”) card, and "The CA card is an interface between the laptop software (which is DOS-based) and the car." .. the CA card was used as custom hardware as part of an integrated system for security and copy protection. In other words, this is part of a system to ensure that nobody but McLaren can access the car software. Their attempt at vendor lock-in has led to vendor lock-in being imposed on them.

UK Spooks Say: Don’t Keep Resetting Your Passwords!?
by Lawrence D'Oliveiro 06 May '16

On World Password Day (who knew?), the Communications-Electronics Security Group (CESG), part of GCHQ, is telling sysadmins not to force their users to keep resetting their passwords <http://www.theregister.co.uk/2016/05/05/stop_resetting_your_password_says_u…>. The result, according to CESG, is that we are more likely to write our password down. Or forget the password altogether, forcing service desks to reset them, chewing up time and resources. So what was wrong with writing them down, again? You know how to keep your cash, credit cards and house keys safe; why can’t you keep your written passwords in the same place? The last three paragraphs of the article are, um, worth reading carefully...

Microsoft unveils new effort to make its documentation great again ... or does it?
by rowan schischka 06 May '16

06 May '16

>Just one problem: while Microsoft itself uses the term ?open sourced? I think you will find that Microsoft will make its own definition of the word 'open'. for example for years they have been calling their bulk license purchasing plan the 'Open License' (OLP, OLV, OVS, etc). Their Open is not GPL. They want hobbyists and students to tinker with their products and if you're not making money they wont bother you. for example they give charities and schools dirt cheap pricing because they just want everyone to use their products. Their bottom line is; if you make money off our product we want our cut of that to return to our investors.

TLS Proxies: Insecure By Design
by Lawrence D'Oliveiro 06 May '16

06 May '16

A “TLS Proxy” short-circuits the security of TLS/SSL connections so it can do deep-packet inspection on encrypted connections. This kind of thing always seemed dodgy. And now it turns out that is so for good reason: these devices are full of holes <http://www.theregister.co.uk/2016/05/05/tls_proxies_are_insecure/>. The paper mentioned there concentrated on consumer/retail devices. But it’s unlikely ones designed for business/enterprise use are going to fare any better...

Unity 8 And Snaps Are Conquering The Ubuntu Desktop After Ubuntu 16.10
by Peter Reutemann 05 May '16

05 May '16

"Today is the last day of the Ubuntu Online Summit 2016, and the Ubuntu developers discussed the future of the Ubuntu Desktop for Ubuntu 16.10 (Yakkety Yak) and beyond. It looks like Snaps (Snappy) and Unity 8 with Mir are slowly conquering the Ubuntu Desktop, at least according to Canonical's Will Cooke, Ubuntu Desktop Manager. Work has already begun on pushing these new and modern technologies to the Ubuntu Desktop, as Ubuntu 16.04 LTS has just received support for installing Snaps from the Ubuntu Snappy Store. Canonical's Will Cooke has mentioned the fact that the Unity 7 desktop enters its twilight years, which means that it gets fewer features and it's being reduced to only critical and OEM work. This is because Unity 8 desktop is getting all the attention now, and it will become the default desktop session somewhere after Ubuntu 16.10 (Yakkety Yak)." -- source: https://news.slashdot.org/story/16/05/05/2038256 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/

<http://arstechnica.com/information-technology/2016/05/microsoft-unveils-new…>: Some teams within Microsoft, such as those developing ASP.NET and .NET Core, had already open sourced their documentation. On the new site, all documentation will be handled similarly. Every article will have an "edit" button enabling changes and fixes to be proposed.

Proprietary Software Riddled With Old Open-Source Vulnerabilities
by Lawrence D'Oliveiro 04 May '16

04 May '16

No big news, really: closed-source software, even if it is built on open-source components, will inevitably accumulate long-standing bugs that never get fixed. And sometimes the bugs have security implications. This report from Black Duck uses the term “commercial” software, but it’s quite clear they mean “proprietary” software, i.e. closed-source <http://www.theregister.co.uk/2016/05/04/commercial_software_chokkas_with_an…>. The telling phrase in the report is “visibility into the components that are included in their code base is required”. How would you *not* have such visibility, if the source of your product is open? A lot of companies may hate copyleft licences, but at least they force a level of transparency that makes this kind of thing much harder to cover up.

Aging and bloated OpenSSL is purged of 2 high-severity bugs

"Maintainers of the OpenSSL cryptographic library have patched high-severity holes that could make it possible for attackers to decrypt login credentials or execute malicious code on Web servers.

fast good unlimited internet

As per the subject it sounds great. Alas this is New Zealand, home of the rapacious duopoly, and one cable outwards. So you won't be looking at 'Spark' (aka former monoply Telecom) or global corp Vodafone. The fast thing has got a bit better since the powers that be finally fibred up at taxayer expense at least in part. Or so I hear. Ultra fast is probably an exaggeration compared with benchmark nations. Long white cloud has some issues with population density and geography. However it sounds like there may be a local option. Tauranga is an opulent region so there must be some money in it for small providers. Until a bigger fish appears bent on acquisition.

Ubuntu Quietly Raises Install Image Size to 2GB

Canonical's Steven Langasek explains the plans for Ubuntu 16.10 Yakkety Yak: "I've finally gone ahead and bumped the limit on Ubuntu desktop images to 2GB for a minimally-sized USB stick; this gives us a new limit that I think we will care about, while also leaving us headroom so we're not constantly fighting it back down to the line." The Ubuntu ISO is supposed to be around the 1GB mark but has creeped past this in recent releases.

From Paintbox to PC: How London became the home of Hollywood VFX
by Lawrence D'Oliveiro 01 May '16

01 May '16

Nice article about the video-effects business, from the Quantel Paintbox to present-day CGI <http://arstechnica.com/the-multiverse/2016/05/how-london-became-the-home-of…>, from Ars Technica UK. Betting on Moore’s Law: Framestore tried to predict when technology would allow them to charge what their clients were willing to pay, and adjust the business accordingly. It was a risky, yet incredibly shrewd plan—and it paid off. This same company went on to make “Walking With Dinosaurs”. Moving away from the legendary SGI workstations of the early 1990s, towards more commodity hardware nowadays: Today, VFX studios are powered by Intel processors, Nvidia graphics cards (all the VFX studios I spoke to used Nvidia graphics cards, citing reasons of driver stability), and Linux operating systems. These parts are just as accessible to consumers as they are to businesses: one only need look at the rise of YouTube and high-quality homemade videos to see just how far the commoditisation of VFX technology has come. But those Nvidia cards are mainly used for on-screen previews, not the final renders: Like the rest of the VFX industry, Pixar is yet to introduce GPUs into its render farms, preferring instead to use them in local or farm-based workstations for quick and dirty lighting previews. It faces the same issue as everyone else: GPUs simply don't have enough memory. Each frame in a final render requires as much 64GB of system memory, with films like Avatar pushing 128GB. The highest-end Nvidia graphics card comes equipped with just 12GB of memory. The article has a strange reluctance to use the term “renderer”. It describes Arnold as “a cutting edge lighting program” and Renderman as “a way to flesh out an existing 3D model or animation with interactive lighting and shading”. One quote I found revealing: At most VFX studios the final render is done at around 2K resolution. It doesn’t qualify this by saying this is for TV work, not for film work. So is 2K enough even for film work? And just like when they moved from TV to film, studios like MPC, Framestore, and Pixar are waiting for technology to catch up with their creative ambitions, even if they're not all convinced 4K is the answer. Meanwhile, some people are managing 4K renders <https://www.youtube.com/results?search_query=blender+foundation+4k> just fine...

The next, “Broxton”, generation of Intel’s Atom chips have been cancelled, along with future SoCs incorporating Atom cores <http://www.theregister.co.uk/2016/04/30/intel_atoms_cancelled/>. I can remember when the first generation of Atom chips were announced, back in 2008 or so with the debut of “netbooks”--remember them? (/me glances at an old Asus Eee 701 sitting within arm’s reach.) Intel claimed it was two years ahead of ARM at that point, and able to offer the “full Internet experience” (which was code for “can run Flash videos”). That “two years ahead” claim went quiet after a few months... I wondered--still wonder--why Intel doesn’t just make ARM chips. It’s got to be more profitable than the billions it has wasted on developing Atom processors that nobody seems to want.

Ubuntu 16.04 LTS Available To Download; Mozilla To Offer 0-Day Firefox Releases Via Snaps

"The latest, and hopefully, the greatest version of Ubuntu is now available to download.

Earlier today, Canonical unleashed the final release of the highly anticipated Ubuntu 16.04 LTS (Xenial Xerus) operating system, bringing users a great set of new features and improvements. Also today, it looks like Canonical has renewed its partnership with Mozilla to offer Firefox as the default web browser on Ubuntu 16.04 LTS and upcoming releases of the Linux kernel-based operating systems. As part of the new partnership, Mozilla is committed to distributing future versions of Firefox as a snap package. Having Firefox distributed in the snap format means that you'll have 0-day releases in Ubuntu 16.04. Yes, just like Windows and Mac OS X, users are enjoying their 0-day releases of Mozilla Firefox and don't have to wait for package maintainers of a particular GNU/Linux distribution to update the software in the main repositories. For Mozilla, having Firefox as a snap package means that they'll be able to continually optimize it for Ubuntu." -- source: https://tech.slashdot.org/story/16/04/21/1940213 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/

The Ars guide to building a Linux router from scratch
by rowan schischka 18 Apr '16

18 Apr '16

A few years ago I built an ap on a pc engines alix board. Of course the choice of wireless card is going to be the deciding factor in performance as the alix's cpu and ram is higher than most wireless appliances. My performance was good but not as good as similar priced appliances. I am not using it atm because I'm using a skinny 4g modem. If I needed a wireless ap in the future I would buy an appliance over built due to cost, time, and performance. What you loose out on appliance ap is software and security upgrades. Also the coolest thing with building a router based on debian is you can install anything you want. But if you want to install proxy server, file server and virus scanners don't go for an embedded chip, get a proper pc with decent cpu and hard drive. And lastly I tested the original raspberry pi as an ap. Throughput was terrible. About 1mb per second file transfer speed using rsync, my understanding is that is due to everything running through its USB controller

The Ars guide to building a Linux router from scratch
by Peter Reutemann 17 Apr '16

17 Apr '16

"After finally reaching the tipping point with off-the-shelf solutions that can't match increasing speeds available, we recently took the plunge. Building a homebrew router turned out to be a better proposition than we could've ever imagined. With nearly any speed metric we analyzed, our little DIY kit outpaced routers whether they were of the $90- or $250-variety." -- source: http://arstechnica.com/gadgets/2016/04/the-ars-guide-to-building-a-linux-ro… 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/

Ubuntu 16.04 LTS Will Bring Snap Packages For Up-To-Date, More Secure Apps
by Peter Reutemann 13 Apr '16

13 Apr '16

"Canonical, Ubuntu's parent company, has announced that Ubuntu 16.04 LTS (Long Term Support) will come with support for the snap packaging format and tools. As a result, end users will get more up-to-date apps, something that proved tricky in the past due âoethe complexity of packaging and providing updates,â which prevented updates to some apps being delivered. Snaps will make the Ubuntu platform more unified, developers will more easily be able to create software for PC, Server, Mobile, or IoT devices. The other major benefit of snaps is that that they're more secure than software installed through deb packages. Snaps are isolated from the rest of the system, meaning that malware packaged with a snap won't be able to affect your Ubuntu installation." -- source: https://news.slashdot.org/story/16/04/13/1627204 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/

The Future of Firefox is Chrome
by Peter Reutemann 13 Apr '16

13 Apr '16

"Mozilla seems to think a new future for Firefox [lies in Chrome]. While they claim that it is only about new ways of browser design, it is also an open secret that they are running into more and more problems lately with web compatibility. [Senior VP Mark Mayo caused a storm by revealing that the Firefox team is working on a next-generation browser that will run on the same technology as Google's Chrome browser. The project, named Tofino, will not use Firefox's core technology, Gecko, but will instead plumb for Electron, which is built on the technology behind Google's rival Chrome browser, called Chromium.] The benefit of Chromium/Electron would be that it is a solution they could pull much faster forward than their own Servo plans [Servo being Mozilla's Rust-based web engine]. What the real outcome of all this will be, only Mozilla knows so far. But inside Mozilla there is much resistance against such plans... Interesting times are ahead." -- source: https://news.slashdot.org/story/16/04/12/2025215 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/

Yes, Badlock bug was shamelessly hyped, but the threat is real
by Peter Reutemann 13 Apr '16

13 Apr '16

"In a nutshell, Badlock refers to a defect in a security component contained in just about every version of the Windows and Linux operating systems. Known as the Distributed Computing Environment/Remote Procedure Call (DCE/RPC), it's used by administrators around the world to access the most valuable asset on any Windows network—the Active Directory, which acts as a network's digital security guard, allowing, for instance, an organization's CFO to log in to an accounting server, while locking out the janitor or the groundskeeper. Because Active Directories enforce security policies and contain password data and other crucial credentials, they are almost always the first asset hackers access once they gain a limited foothold into a targeted network." "An Active Directory infrastructure with a Samba server as a domain member is vulnerable to this flaw," an advisory published Tuesday by Linux distributor Red Hat warned. "A man-in-the-middle attacker could intercept DCE/RPC traffic between the domain member and the domain controller to impersonate the client and get the same privileges as the authenticated user account. The attacker could view or modify secrets within an AD database, including user password hashes, or shutdown critical services." -- source: http://arstechnica.com/security/2016/04/yes-badlock-bug-was-shamelessly-hyp… 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/

Popular Firefox Add-Ons Open Millions To New Attack
by Peter Reutemann 09 Apr '16

09 Apr '16

'Security researchers claim that NoScript and other popular Firefox add-on extensions are exposing millions of end users to a new type of vulnerability which, if exploited, can allow an attacker to execute malicious code and steal sensitive data. The vulnerability resides in the way Firefox extensions interact with each other. From a report on SlashGear, "The problem is that these extensions do not run sandboxed and are able to actually access data or functions from other extensions that are also enabled. This could mean, for example, that a malware masquerading as an add-on can access the functionality of one add-on to get access to system files or the ability of another add-on to redirect users to a certain web page, usually a phishing scam page. In the eyes of Mozilla's automated security checks, the devious add-on is blameless as it does nothing out of the ordinary."' 'Firefox's VP of Product acknowledged the existence of the aforementioned vulnerability. "Because risks such as this one exist, we are evolving both our core product and our extensions platform to build in greater security. The new set of browser extension APIs that make up WebExtensions, which are available in Firefox today, are inherently more secure than traditional add-ons, and are not vulnerable to the particular attack outlined in the presentation at Black Hat Asia. As part of our electrolysis initiative -- our project to introduce multi-process architecture to Firefox later this year -- we will start to sandbox Firefox extensions so that they cannot share code."' -- source: https://it.slashdot.org/story/16/04/09/1758255 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/

Researchers Help Shut Down Spam Botnet That Enslaved 4, 000 Linux Machines
by Peter Reutemann 09 Apr '16

09 Apr '16

'A botnet that enslaved about 4,000 Linux computers and caused them to blast the Internet with spam for more than a year has finally been shut down. Sophisticated Mumblehard spamming malware flew under the radar for five years. Known as Mumblehard, the botnet was the product of highly skilled developers. It used a custom "packer" to conceal the Perl-based source code that made it run, a backdoor that gave attackers persistent access, and a mail daemon that was able to send large volumes of spam. Command servers that coordinated the compromised machines' operations could also send messages to Spamhaus requesting the delisting of any Mumblehard-based IP addresses that sneaked into the real-time composite blocking list, or CBL, maintained by the anti-spam service. "There was a script automatically monitoring the CBL for the IP addresses of all the spam-bots," researchers from security firm Eset wrote in a blog post published Thursday. "If one was found to be blacklisted, this script requested the delisting of the IP address. Such requests are protected with a CAPTCHA to avoid automation, but OCR (or an external service if OCR didn't work) was used to break the protection."' -- source: https://linux.slashdot.org/story/16/04/09/1827238 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/

Developer Warns Of "Uncorrectable Freedom & Security Issues" For x86
by Lawrence D'Oliveiro 05 Apr '16

05 Apr '16

Modern Intel and AMD x86 chips cannot even boot up without various pieces of locked-down proprietary binary firmware. Effectively this is an OS-within-an-OS, that retains ultimate control of the processor, regardless of what the owner of the machine might want. <http://phoronix.com/scan.php?page=news_item&px=x86-Uncorrectable-Freedom>

Microsoft Windows Linux Take 2
by Lawrence D'Oliveiro 30 Mar '16

30 Mar '16

From <http://arstechnica.com/information-technology/2016/03/ubuntus-bash-and-linu…>: ...we've known for several months now is that the company has developed some Windows kernel components (lxcore.sys, lxss.sys, presumably standing for "Linux core" and "Linux subsystem," respectively) that support the major Linux kernel APIs. ... Microsoft is calling this the "Windows Subsystem for Linux" (WSL). ... Canonical has provided a system image containing the Ubuntu versions of the various command-line tools that are typically found in a Linux distribution. Our understanding is that these are not recompiled or ported versions of the programs (as are used in tools aiming to provide a Unix-like environment on Windows such as Cygwin) but instead unmodified programs. Microsoft is describing this in terms of providing a Linux-like command-line environment at the moment, but from what we can gather, there's little fundamental restriction to this, potentially opening the door to running a wide range of Linux programs natively on Windows. Absolutely nothing to do with the fact that tomorrow is April 1...

Red Hat Achieves 2 Billion USD In Annual Revenue
by Lawrence D'Oliveiro 23 Mar '16

23 Mar '16

Red Hat has taken just 2 years to double its annual takings <http://phoronix.com/scan.php?page=news_item&px=Red-Hat-Two-Billion>. I remember a senior executive saying some years ago that for every dollar of revenue they get, they take $10 away from their proprietary rivals. So their overall effect on the market is massively deflationary.

How to maintain my connection to squeeze
by Chris O'Halloran 12 Mar '16

12 Mar '16

Hi all, I have a server at work that is hacked and customized to bits to keep a wiki going using mediawiki [1] software including node.js [1a] binaries. It was a turneky [2] appliance based on Debian 6 or squeeze. It's work very well these past 6 or 7 years. It also runs a ruby on rails app clockingit.[3] I've installed the anaconda python distribution [4] on it and that is running fine. It was the only way to get python 3.4 running nicely with notebooks. A thing I've been tinkering with lately is the latex circuit package circuitikz [5] for my making nice circuit diagrams and another bit of ipython magics [6] allows you to insert these into your ipython notebooks. I know this keeps putting off the inevitable but I'd rather procrastinate further than rebuild the server. It seems squeeze has experienced some sort of migration to an LTS release even though officially it's not longer supported. The point is, I'd like to sudo apt-get install texlive-science but say it will have problems chris(a)wiki apt/sources.list.d$ sudo apt-get install texlive-science Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: texlive-science : Depends: python2.7 but it is not going to be installed Depends: texlive-base (>= 2015) but it is not going to be installed Depends: texlive-latex-base (>= 2015) but it is not going to be installed Depends: tex-common (>= 6) but 2.08.1 is to be installed Depends: texlive-latex-recommended (>= 2015) but it is not going to be installed Depends: texlive-binaries (>= 2015.20160222.37495-1) but 2009-8 is to be installed E: Broken packages when I do sudo apt-get update Err http://cdn.debian.net squeeze/main amd64 Packages 404 Not Found [IP: 180.214.94.18 80] Err http://cdn.debian.net squeeze/contrib amd64 Packages 404 Not Found [IP: 180.214.94.18 80] Err http://cdn.debian.net squeeze/non-free amd64 Packages 404 Not Found [IP: 128.61.240.89 80] Fetched 39.3 kB in 7s (5257 B/s) W: There is no public key available for the following key IDs: 7638D0442B90D010 W: Failed to fetch http://cdn.debian.net/debian/dists/squeeze/main/binary-amd64/Packages.gz 404 Not Found [IP: 180.214.94.18 80] W: Failed to fetch http://cdn.debian.net/debian/dists/squeeze/contrib/binary-amd64/Packages.gz 404 Not Found [IP: 180.214.94.18 80] W: Failed to fetch http://cdn.debian.net/debian/dists/squeeze/non-free/binary-amd64/Packages.gz 404 Not Found [IP: 128.61.240.89 80] So is seems I need to update the squeeze sources to still access the old repos. I'm nervous about upgrading because of all the customisations and don't wish to break things. Any clues on how I have have my server still able to download old packages.

Former Microsoft CEO No Longer Negatively Attacks Linux
by Lawrence D'Oliveiro 11 Mar '16

Interview with Steve Ballmer linked from <http://phoronix.com/scan.php?page=news_item&px=Ballmer-Linux-Cancer-Free>: Fifteen years after calling the open-source operating system Linux a "cancer," former Microsoft Corp (MSFT.O) Chief Executive Steve Ballmer has softened his position. Speaking on Wednesday night at a dinner hosted by Fortune magazine, Ballmer said the position was right for the time, but the threat from Linux was now "in the rearview mirror." Which is why Microsoft is spending more effort than ever on Linux, no doubt...
