Reglue: Opening Up the World To Deserving Kids With Linux Computers 80

Posted by Soulskill
from the never-too-early-for-your-first-tux dept.
jrepin writes: Today, a child without access to a computer (and the Internet) at home is at a disadvantage before he or she ever sets foot in a classroom. The unfortunate reality is that in an age where computer skills are no longer optional, far too many families don't possess the resources to have a computer at home. Linux Journal recently had the opportunity to talk with Ken Starks about his organization, Reglue (Recycled Electronics and Gnu/Linux Used for Education) and its efforts to bridge this digital divide.

Valencia Linux School Distro Saves 36 Million Euro 153

Posted by timothy
from the oh-no-big-deal dept.
jrepin (667425) writes "The government of the autonomous region of Valencia (Spain) earlier this month made available the next version of Lliurex, a customisation of the Edubuntu Linux distribution. The distro is used on over 110,000 PCs in schools in the Valencia region, saving some 36 million euro over the past nine years, the government says." I'd lke to see more efforts like this in the U.S.; if mega school districts are paying for computers, I'd rather they at least support open source development as a consequence.

A Router-Based Dev Board That Isn't a Router 53

Posted by timothy
from the hook-it-to-anything dept.
An anonymous reader writes with a link to an intriguing device highlighted at Hackaday (it's an Indiegogo project, too, if it excites you $90 worth, and seems well on its way to meeting its modest goal): The DPT Board is something that may be of interest to anyone looking to hack up a router for their own connected project or IoT implementation: hardware based on a fairly standard router, loaded up with OpenWRT, with a ton of I/O to connect to anything.

It's called the DPT Board, and it's basically an hugely improved version of the off-the-shelf routers you can pick up through the usual channels. On board are 20 GPIOs, USB host, 16MB Flash, 64MB RAM, two Ethernet ports, on-board 802.11n and a USB host port. This small system on board is pre-installed with OpenWRT, making it relatively easy to connect this small router-like device to LED strips, sensors, or whatever other project you have in mind.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken" 713

Posted by timothy
from the you'll-never-believe-what-he-actually-said dept.
hypnosec (2231454) writes to point out a pointed critique from Linus Torvalds of GCC 4.9.0. after a random panic was discovered in a load balance function in Linux 3.16-rc6. in an email to the Linux kernel mailing list outlining two separate but possibly related bugs, Linus describes the compiler as "terminally broken," and worse ("pure and utter sh*t," only with no asterisk). A slice: "Lookie here, your compiler does some absolutely insane things with the spilling, including spilling a *constant*. For chrissake, that compiler shouldn't have been allowed to graduate from kindergarten. We're talking "sloth that was dropped on the head as a baby" level retardation levels here .... Anyway, this is not a kernel bug. This is your compiler creating completely broken code. We may need to add a warning to make sure nobody compiles with gcc-4.9.0, and the Debian people should probably downgrate their shiny new compiler."

GOG.com Announces Linux Support 81

Posted by Soulskill
from the year-of-linux-on-the-gamebox dept.
For years, Good Old Games has made a business out of selling classic PC game titles completely free of DRM. Today they announced that their platform now supports Linux. They said, We've put much time and effort into this project and now we've found ourselves with over 50 titles, classic and new, prepared for distribution, site infrastructure ready, support team trained and standing by ... We're still aiming to have at least 100 Linux games in the coming months, but we've decided not to delay the launch just for the sake of having a nice-looking number to show off to the press. ... Note that we've got many classic titles coming officially to Linux for the very first time, thanks to the custom builds prepared by our dedicated team of penguin tamers. ... For both native Linux versions, as well as special builds prepared by our team, GOG.com will provide distro-independent tar.gz archives and support convenient DEB installers for the two most popular Linux distributions: Ubuntu and Mint, in their current and future LTS editions.

Ask Slashdot: Linux Login and Resource Management In a Computer Lab? 98

Posted by timothy
from the explain-your-system dept.
New submitter rongten (756490) writes I am managing a computer lab composed of various kinds of Linux workstations, from small desktops to powerful workstations with plenty of RAM and cores. The users' $HOME is NFS mounted, and they either access via console (no user switch allowed), ssh or x2go. In the past, the powerful workstations were reserved to certain power users, but now even "regular" students may need to have access to high memory machines for some tasks. Is there a sort of resource management that would allow the following tasks? To forbid a same user to log graphically more than once (like UserLock); to limit the amount of ssh sessions (i.e. no user using distcc and spamming the rest of the machines, or even worse, running in parallel); to give priority to the console user (i.e. automatically renicing remote users jobs and restricting their memory usage); and to avoid swapping and waiting (i.e. all the users trying to log into the latest and greatest machine, so have a limited amount of logins proportional to the capacity of the machine). The system being put in place uses Fedora 20, and LDAP PAM authentication; it is Puppet-managed, and NFS based. In the past I tried to achieve similar functionality via cron jobs, login scripts, ssh and nx management, and queuing system — but it is not an elegant solution, and it is hacked a lot. Since I think these requirements should be pretty standard for a computer lab, I am surprised to see that I cannot find something already written for it. Do you know of a similar system, preferably open source? A commercial solution could be acceptable as well.

Exodus Intelligence Details Zero-Day Vulnerabilities In Tails OS 132

Posted by timothy
from the compared-to-what? dept.
New submitter I Ate A Candle (3762149) writes Tails OS, the Tor-reliant privacy-focused operating system made famous by Edward Snowden, contains a number of zero-day vulnerabilities that could be used to take control of the OS and execute code remotely. At least that's according to zero-day exploit seller Exodus Intelligence, which counts DARPA amongst its customer base. The company plans to tell the Tails team about the issues "in due time", said Aaron Portnoy, co-founder and vice president of Exodus, but it isn't giving any information on a disclosure timeline. This means users of Tails are in danger of being de-anonymised. Even version 1.1, which hit public release today (22 July 2014), is affected. Snowden famously used Tails to manage the NSA files. The OS can be held on a USB stick and leaves no trace once removed from the drive. It uses the Tor network to avoid identification of the user, but such protections may be undone by the zero-day exploits Exodus holds.

M-Saunders (706738) writes The death of print has been predicted for years, and many magazines and publishers have taken a big hit with the rise of eBooks and tablets. But not everyone has given up. Four geeks quit their job at an old Linux magazine to start Linux Voice, an independent GNU/Linux print and digital mag with a different publishing model: giving profits and content back to the community. Six months after a successful crowdfunding campaign, the magazine is going well, so here is the full story.

MicroxWin Creates Linux Distribution That Runs Debian/Ubuntu & Android Apps 42

Posted by samzenpus
from the all-in-one dept.
An anonymous reader writes VolksPC who developed MicroXwin as a lightweight X Window Server has come up with their own Linux distribution. Setting apart VolksPC's distribution from others is that it's based on both Debian and Android and has the capability to run Debian/Ubuntu/Android apps together in a native ARM experience. The implementation doesn't depend on VNC or other similar solutions of the past that have tried to join desktop apps with mobile Android apps. This distribution is also reportedly compatible with all Android applications. The distribution is expected to begin shipping on an ARM mini-PC stick.

Linux Needs Resource Management For Complex Workloads 161

Posted by Soulskill
from the dirty-job-but-somebody's-gotta-do-it dept.
storagedude writes: Resource management and allocation for complex workloads has been a need for some time in open systems, but no one has ever followed through on making open systems look and behave like an IBM mainframe, writes Henry Newman at Enterprise Storage Forum. Throwing more hardware at the problem is a costly solution that won't work forever, he notes.

Newman writes: "With next-generation technology like non-volatile memories and PCIe SSDs, there are going to be more resources in addition to the CPU that need to be scheduled to make sure everything fits in memory and does not overflow. I think the time has come for Linux – and likely other operating systems – to develop a more robust framework that can address the needs of future hardware and meet the requirements for scheduling resources. This framework is not going to be easy to develop, but it is needed by everything from databases and MapReduce to simple web queries."

New Mayhem Malware Targets Linux and UNIX-Like Servers 168

Posted by Soulskill
from the keep-calm-and-patch-on dept.
Bismillah writes: Russian security researchers have spotted a new malware named Mayhem that has spread to 1,400 or so Linux and FreeBSD servers around the world, and continues to look for new machines to infect. And, it doesn't need root to operate. "The malware can have different functionality depending on the type of plug-in downloaded to it by the botmaster in control, and stashed away in a hidden file system on the compromised server. Some of the plug-ins provide brute force cracking of password functionality, while others crawl web pages to scrape information. According to the researchers, Mayhem appears to be the continuation of the Fort Disco brute-force password cracking attack campaign that began in May 2013."

LibreSSL PRNG Vulnerability Patched 151

Posted by Soulskill
from the looking-forward-to-the-next-two-day-panic dept.
msm1267 writes: The OpenBSD project late last night rushed out a patch for a vulnerability in the LibreSSL pseudo random number generator (PRNG). The flaw was disclosed two days ago by the founder of secure backup company Opsmate, Andrew Ayer, who said the vulnerability was a "catastrophic failure of the PRNG." OpenBSD founder Theo de Raadt and developer Bob Beck, however, countered saying that the issue is "overblown" because Ayer's test program is unrealistic. Ayer's test program, when linked to LibreSSL and made two different calls to the PRNG, returned the exact same data both times.

"It is actually only a problem with the author's contrived test program," Beck said. "While it's a real issue, it's actually a fairly minor one, because real applications don't work the way the author describes, both because the PID (process identification number) issue would be very difficult to have become a real issue in real software, and nobody writes real software with OpenSSL the way the author has set this test up in the article."

from the wobblier-windows dept.
KDE Community (3396057) writes "KDE proudly announces the immediate availability of Plasma 5.0, providing a visually updated core desktop experience that is easy to use and familiar to the user. Plasma 5.0 introduces a new major version of KDE's workspace offering. The new Breeze artwork concept introduces cleaner visuals and improved readability. Central work-flows have been streamlined, while well-known overarching interaction patterns are left intact. Plasma 5.0 improves support for high-DPI displays and ships a converged shell, able to switch between user experiences for different target devices. Changes under the hood include the migration to a new, fully hardware-accelerated graphics stack centered around an OpenGL(ES) scenegraph. Plasma is built using Qt 5 and Frameworks 5." sfcrazy reviewed the new desktop experience. It would appear the semantic desktop search features finally work even if you don't have an 8-core machine with an SSD.

OpenWRT 14.07 RC1 Supports Native IPv6, Procd Init System 71

Posted by Unknown Lamer
from the bofh-excuse-#3847-replacing-router-os dept.
An anonymous reader writes Release Candidate One of OpenWRT 14.07 "Barrier Breaker" is released. Big for this tiny embedded Linux distribution for routers in 14.07 is native IPv6 support and the procd init system integration. The native IPv6 support is with the RA and DHCPv6+PD client and server support plus other changes. Procd is OpenWRT's new preinit, init, hotplug, and event system. Perhaps not too exciting is support for upgrading on devices with NAND, and file system snapshot/restore so you can experiment without fear of leaving your network broken. There's also experimental support for the musl standard C library.

New Raspberry Pi Model B+ 202

Posted by samzenpus
from the latest-and-greatest dept.
mikejuk writes The Raspberry Pi foundation has just announced the Raspberry Pi B+. The basic specs haven't changed much — same BC2835 and 512MB of RAM and the $35 price tag. There are now four USB ports, which means you don't need a hub to work with a mouse, keyboard and WiFi dongle. The GPIO has been expanded to 40 pins, but don't worry: you can plug your old boards and cables into the lefthand part of the connector, and it's backward compatible. As well as some additional general purpose lines, there are two designated for use with I2C EEPROM. When the Pi boots it will look for custom EEPROMs on these lines and optionally use them to load Linux drivers or setup expansion boards. Expansion boards can now include identity chips that when the board is connected configures the Pi to make use of them — no more manual customization. The change to a micro SD socket is nice, unless you happen to have lots of spare full size SD cards around. It is also claimed that the power requirements have dropped by half, to one watt, which brings the model B into the same power consumption area as the model A. Comp video is now available on the audio jack, and the audio quality has been improved. One big step for Raspberry Pi is that it now has four holes for mounting in standard enclosures.

Prof. Andy Tanenbaum Retires From Vrije University 136

Posted by timothy
from the congratulations-and-good-wishes dept.
When Linus Torvalds first announced his new operating system project ("just a hobby, won't be big and professional like gnu"), he aimed the announcement at users of Minix for a good reason: Minix (you can download the latest from the Minix home page) was the kind of OS that tinkerers could afford to look at, and it was intended as an educational tool. Minix's creator, Professor Andrew Stuart "Andy" Tanenbaum, described his academic-oriented microkernel OS as a hobby, too, in the now-famous online discussion with Linus and others. New submitter Thijssss (655388) writes with word that Tanenbaum, whose educational endeavors led indirectly to the birth of Linux, is finally retiring. "He has been at the Vrije Universiteit for 43 years, but everything must eventually end."

Microsoft Backs Open Source For the Internet of Things 136

Posted by samzenpus
from the free-and-open dept.
dcblogs writes Microsoft has joined a Linux Foundation effort to create an open platform for the Internet of Things. The AllSeen Alliance is an effort to standardize device communications. The code that it champions, called AllJoyn, was initially developed by Qualcomm but was subsequently made open source. Big vendors have been recruited to support it, and the AllSeen Alliance now includes LG, Panasonic, Sharp and Haier, among others. Its Xbox gaming platform is seen as a potential hub or control center for home devices. Microsoft's leadership in computing "and its significant Xbox business make it a potentially important contributor to the AllSeen ecosystem," said said Andy Castonguay, an analyst at Machina Research, a Reading, England-based research firm focusing on machine-to-machine (M2M) communications and the Internet of Things.
