Debian’s Reproducible Binary Project Reaches 83% Mark
by Lawrence D'Oliveiro 24 Feb '15

24 Feb '15

For a while now, Debian has been running a project to try to allow anyone to independently confirm that a particular Debian package was indeed built from a particular set of sources, by being able to reproduce the exact build steps themselves. (The security rationale for wanting to do so should be obvious.) As you can imagine, this is seriously non-trivial to achieve, since the least little difference in the version of your compilers or libraries can cause the binaries to differ, maybe not in any important way, but the idea is to end up with no differences at all. The Register has a report on the status of the project here <http://www.theregister.co.uk/2015/02/23/debian_project/>. More background here <https://lists.debian.org/debian-devel-announce/2015/02/msg00007.html>.

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

24 Feb '15

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

How I upgraded my garden’s ugly drip system with a sexy OpenSprinkler
by Peter Reutemann 23 Feb '15

"After a few hours of work alongside an electrical engineering buddy this week, my home garden drip system became powered by a Raspberry Pi. I can control the entire thing locally from my iPhone and, to be frank, it’s pretty flippin’ cool." -- source: http://goo.gl/sDPGsr Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

“SSL hijacker” behind Superfish debacle imperils large number of users
by Peter Reutemann 21 Feb '15

21 Feb '15

I know, this is not strictly Linux related, but scary nonetheless and worthy of sharing, IMHO: "Thursday's revelations that Lenovo PCs ship with adware that intercepts sensitive HTTPS-protected traffic have focused intense scrutiny on Superfish, the company that markets the intrusive software. But lost in the furor is the central role a company called Komodia plays in needlessly exposing the passwords and other sensitive data of not just Lenovo customers but also a much larger base of PC users." -- source: http://goo.gl/KhA4KT Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Empire of the Gates
by Ian Young 20 Feb '15

20 Feb '15

Better snap back to reality. On Arstechnica I see the following data as of 11/2014. OS share worldwide -- Windows allsorts 91.28%, OS X 7.27, all others [weeps] 1.45. Windows breakdown XP 13.57%, Vista 2.65, Win 7 56.41, Win 8 6.55, Win 8.1 12.1. http://arstechnica.com/gadgets/2015/01/you-can-offer-people-windows-10-for-… All hail his Billness. Though the figures for systems other than desktops must show a different story, and in phone and tablet world Windows is pretty well a joke apart from some misguided corporate purchases. (I stand to be corrected on that). Meanwhile back in the day, I had GEOS installed and it was passable. Even ran it within OS/2, freaky or what? Speaking of OS/2 last time I looked there were still some zealots keeping it working after a fashion. -quote- Unfortunately, OS/2 had a crucial flaw in its design: a Synchronous Input Queue (SIQ). What this meant was that all messages to the GUI window server went through a single tollbooth. If any OS/2 native GUI app ever stopped servicing its window messages, the entire GUI would get stuck and the system froze. OK, technically the operating system was still running. Background tasks continued to execute just fine. You just couldn’t see them or interact with them or do anything, because the entire GUI was hung. Some enterprising OS/2 fan wrote an application that polled the joystick port and was supposed to unstick things when the user pressed a button. It rarely worked. Ironically, if you never ran native OS/2 applications and just ran DOS and Windows apps in a VM, the operating system was much more stable. -quote- http://arstechnica.com/business/2013/11/half-an-operating-system-the-triump… And now we return to our normal programme and wonder whether Linux v4 is soon to arrive. 19 million lines in the kernel and counting. http://linuxgizmos.com/is-linux-heading-toward-the-big-4-0/

Raspberry π 2 Ships Half Million In First Two Weeks
by Lawrence D'Oliveiro 20 Feb '15

20 Feb '15

The next-generation Raspberry π seems to be doing rather well right out of the starting gate <http://www.theinquirer.net/inquirer/news/2395948/raspberry-pi-2-sales-top-5…>. Meantime, while total sales of both old- and new-generation π models have wildly exceeded expectations, there is some dispute over the Foundation’s claim that it has become the best-selling British PC maker ever <http://www.theregister.co.uk/2015/02/18/raspberry_pi_5_million_sold/>.

A History Of Photoshop

Quite a few articles around to celebrate the 25th anniversary of Photoshop 1.0, but this one at The Register <http://www.theregister.co.uk/2015/02/19/feature_25_years_of_adobe_photoshop/> seems to offer the most background detail. And some nice (or not-so-nice) examples of its use...

Microsoft's First Azure Hosted Service Is Powered By Linux
by Peter Reutemann 19 Feb '15

19 Feb '15

"Canonical, through John Zannos, VP Cloud Alliances, has proudly announced that the first ever Microsoft Azure hosted service will be powered by Ubuntu Linux. This piece of news comes from the Strata + Hadoop World Conference, which takes place this week in California. The fact of the matter is that the news came from Microsoft who announced the preview of Azure HDInsight (an Apache Hadoop-based hosted service) on Ubuntu clusters yesterday at the said event. This is definitely great news for Canonical, as their operating system is getting recognized for being extremely reliable when handling Big Data. Ubuntu is now the leading cloud and scale-out Linux-based operating system." -- source: http://hardware.slashdot.org/story/15/02/19/1830232 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Arduino Ructions
by Lawrence D'Oliveiro 19 Feb '15

19 Feb '15

Seems like the Arduino founders have split to go their separate ways <https://www.techdirt.com/articles/20150217/10345530055/is-arduino-heading-t…>. The unfortunate thing is that there are now lawsuits to try to decide who has exclusive rights to the “Arduino” name. Whatever happens, it seems likely there will continue to be more than one company making products that are “Arduino” in every way, if not in name. This is nothing new in open-source software, though it may be a first for open-source hardware.

Seymour Cray’s Only Surviving Talk
by Lawrence D'Oliveiro 19 Feb '15

19 Feb '15

Seymour Cray, who was practically “Mister Supercomputer” through the 1960s, 70s and 80s, gives a talk at Los Alamos discussing the pending introduction of the legendary Cray-1 <https://www.youtube.com/watch?v=vtOA1vuoDgQ>. The date given in the title is 1976, but he repeatedly makes remarks in the talk that point to the year actually being 1974. He says the new machine will be installed at LANL the following year (actually it went in in 1976).
