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/

"Non-game Android apps are normally written in Java, but a group inside Google is experimenting with a whole new way of writing Android apps using Dart, Google's in-house Web development language. It's Android apps with no Java, a focus on speed, and deep integration with the Web." -- source: http://arstechnica.com/gadgets/2015/05/01/googles-dart-language-on-android-… 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/

'Coming in at the same $35 price-point that has come to be expected from the Raspberry Pi, it looks like the new Model 2 will be packing a quad-core ARM processor with a GB of RAM. From the article: "The Raspberry Pi Foundation is likely to provoke a global geekgasm today with the surprise release of the Raspberry Pi 2 Model B: a turbocharged version of the B+ boasting a new Broadcom BCM2836 900MHz quad-core system-on-chip with 1GB of RAM – all of which will drive performance "at least 6x" that of the B+."' -- source: http://build.slashdot.org/story/15/02/02/0134211 And also in the news: "Microsoft Announces Windows For Raspberry Pi 2 Microsoft is expanding their Windows Developer Program for Internet of Things by delivering a version of Windows 10 that runs on the Raspberry Pi 2. This release of Windows 10 will be free for the maker community through the Windows Developer Program for IoT. With an official partnership with the Raspberry Pi Foundation, Microsoft is bringing development tools, services and ecosystem to the Raspberry Pi community. More details will be shared in the coming months. You can already join the program and be amongst the first to receive product information and beta software releases." -- source: http://hardware.slashdot.org/story/15/02/02/1326225 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

"Several thousand computers running the Linux and FreeBSD operating systems have been infected over the past seven months with sophisticated malware that surreptitiously makes them part of a renegade network blasting the Internet with spam, researchers said Wednesday.

"Users can change the system clock without authenticating It appears that there's a bug in Ubuntu distributions which lets malicious users locally exploit sudo and gain access to the user's account without knowing their password.

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/>
