Linux Kernel 4.2 Released
by Peter Reutemann 30 Aug '15

30 Aug '15

"The Linux 4.2 kernel is now available. This kernel is one of the biggest kernel releases in recent times and introduces rewrites of some of the kernel's Intel Assembly x86 code, new ARM board support, Jitter RNG improvements, queue spinlocks, the new AMDGPU kernel driver, NCQ TRIM handling, F2FS per-file encryption, and many other changes to benefit most Linux users." -- source: http://linux.slashdot.org/story/15/08/30/1949211 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 Is Broken In Debian Unstable
by Lawrence D'Oliveiro 29 Aug '15

29 Aug '15

Looks like KDE is in the middle of a major transition in Debian Unstable at the moment. Yesterday I did an update on my backup machine, and found that I had no window manager after logging into the GUI. 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...

Learn FPGAs With a $25 Board and Open Source Tools
by Peter Reutemann 27 Aug '15

27 Aug '15

"Hackaday has a 3 part tutorial with videos of using open source tools with a cheap ($25) FPGA board. The board isn't very powerful, but this could be the 'gateway drug' to FPGAs for people who don't want to spend hundreds of dollars and install 100s of megabytes of software and license keys just to get their feet wet. The videos are particularly good--like watching them over their shoulder. As far as I know, this is the only totally open source FPGA toolchain out there." -- source: http://hardware.slashdot.org/story/15/08/27/226232 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/

Hi everyone Great to see people discussing topics on the mailing list! How about we have a discussion about email encryption (incl signing) and network privacy at the next meeting? If I remember correctly, Hieu's Pi presentation will be relatively short, so we should have plenty of time.

Happy Birthday, Linux! An OS At 24
by Peter Reutemann 26 Aug '15

26 Aug '15

"It has been 24 long years since the first ever release of the Linux project on August 25, 1991, which is the core component of any GNU/Linux distribution. With this occasion we want to remind everyone that Linux is everywhere, even if you don't see it. You use Linux when you search on Google, when you use your phone, when buy metro tickets, actually the whole Internet is powered by Linux.

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/

Engaging Newbies In Email Encryption and Network Privacy
by Peter Reutemann 25 Aug '15

25 Aug '15

"All six parts of my series introducing beginners to PGP encryption and network privacy are now freely available. I hope it's useful for Slashdot readers to share with their less-technical acquaintances. There's an introduction to PGP, a guide to email encryption on the desktop, smartphone and in the browser, an introduction to the emerging key sharing and authentication startup, Keybase.io, and an intro to VPNs. There's a lot more work for us to do in the ease of use of communications privacy but this helps people get started more with what's available today." -- source: http://it.slashdot.org/story/15/08/20/2041235 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/

Mozilla sets plan to dump Firefox add-ons, move to Chrome-like extensions
by Peter Reutemann 23 Aug '15

23 Aug '15

"Back in July, Mozilla disclosed plans to modernize its Firefox browser. Today, the organization made those plans more concrete, with a tentative timeline for introducing long-desired improvements such as the creation of a process per tab—and with it, a timeline for the end of support for traditional Firefox add-ons. Mozilla has been working on a multi-process architecture for years. Called the Electrolysis project, work started in 2009, but was put on hold in 2011. Work was resumed in 2013, and it's finally getting near to a release. Over the next few months, Mozilla plans to flip the switch and enable Electrolysis in its various release channels. Tentatively, it'll be an opt-in feature in the beta channel from September 22nd, on-by-default in the beta channel from November 3rd, and on-by-default in the release channel from December 15th." -- source: http://arstechnica.com/information-technology/2015/08/mozilla-sets-plan-to-… 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 Core Gets Support For Raspberry Pi 2 GPIO and I2C
by Peter Reutemann 23 Aug '15

23 Aug '15

"Ubuntu Core is a tiny Ubuntu distribution aimed at the Internet of Things, using a new transactional packaging format called Snappy rather than the venerable Debian packaging format. It recently gained support for I2C and GPIO on the Raspberry Pi 2, and a quick demo is given here."

Please, OpenOffice, Die Already
by Lawrence D'Oliveiro 20 Aug '15

20 Aug '15

Well, maybe not in so many words, but some are saying <http://lwn.net/Articles/654776/> that OpenOffice has reached (i.e. declined) to the stage where it is getting in the way of people looking for a powerful Free Software office suite. They never hear of LibreOffice, find OpenOffice instead, and are disappointed with its (lack of) capabilities.

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.

Windows 10 From a Linux User's Perspective
by Peter Reutemann 13 Aug '15

13 Aug '15

"I've spent quite a bit of time testing out Windows 10 on a secondary computer. And like any operating system upgrade, the change takes a bit to get used to. Since I feel more comfortable with Linux distributions than with Windows, I thought it would be interesting to see what Microsoft has done since Windows 7 and 8. In this article, I'll walk you through how I see Windows 10. What it did well, where it falls flat on its face and how this appears to a hardcore Linux enthusiast." -- source: http://www.linuxtoday.com/infrastructure/windows-10-from-a-linux-users-pers… 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/

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

"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?
by Lawrence D'Oliveiro 06 Aug '15

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/
