3D Printer Controlled With a Touch-Screen Linux Tablet 30

Posted by timothy
from the make-new-chess-pieces-anywhere dept.
New submitter drachensun writes "Francesco Santini was looking into the possibilities of stand-alone printing with the Solidoodle. He choose the PengPod 700, a tablet that runs a full Linux distribution and turned it into a standalone interface for the SD2. 'So, in summary, I now have a fully-functional touchscreen pronterface installation that can drive the Solidoodle, for a total cost of 110$. No assembly, soldering, firmware modding required. Just a little bit of fiddling with Linux (if required, I can post a step-by-step guide, or prepare an ad-hoc linux image).'"

The 'Linux Inside' Stigma 366

Posted by Soulskill
from the someday-they'll-even-come-up-with-a-linux-phone dept.
New submitter dtschmitz highlights the success of the Google Chromebook to underscore what, in his view, is a serious Linux brand image problem. "It's remarkable how Google doesn't mention the word Linux anywhere in their marketing of the Google Chromebook. I mean, it's running the Linux Kernel, so shouldn't it be Google Linux instead of ChromeOS? Why did Google carefully avoid references to Linux? It's all a very carefully crafted, well executed plan of elegant branding and image making. ... The profile of this user is that of someone who really doesn't care anything about the technical underpinnings of a device. They are not sophisticated technophiles by any means. They have a set number of things which they wish to do--recreational surfing, banking, email, an occasional letter, not complicated. ... Google didn't mention Linux because they know it will scare buyers away. That's unfortunate, but true. And we need to come to terms with that fact and work towards improving the 'Linux Inside' brand image.

Remote Desktop Backend Merged into Wayland 215

Posted by Unknown Lamer
from the thought-no-one-used-that-feature dept.
New submitter Skrapion writes "One month ago, an independent developer submitted patches to the Wayland's Weston compositor which adds support for FreeRDP, an open-source remote desktop protocol. Now, after six revisions, the remote desktop code has been merged into the trunk. While remote desktop has been prototyped in Weston once before by Wayland developer Kristian Høgsberg, this is the first time Wayland/Weston has officially supported the feature. For a summary of why we can expect Wayland's remote desktop to surpass X.Org's network transparency, see Daniel Stone's excellent talk from Linux.conf.au."

Valve Starts Publishing Packages For Its Own Linux Distribution 310

from the ready-for-the-console-at-least dept.
An anonymous reader writes "In preparation for the "Steam Box" game console that will make necessary their own Linux-based software platform, Valve developers have started publishing Debian packages for their platform which looks like their first-generation operating system will be derived from Ubuntu 12.04.2 LTS. So far the packages being published include a new "Plymouth" boot splash screen as the operating system loads, a Steam desktop wallpaper, auto-updating system scripts, and experimental NVIDIA Linux graphics drivers."

Systemd Ditches GNU C Library for Their Own 92

Posted by Unknown Lamer
from the watch-the-world-fork dept.
In his typical fashion of replacing perfectly working software with useless broken-by-design crap, our dearest Lennart has decided that the time has come for systemd to gain an email program. He determined that the GNU libc was insufficient for the task of a dbus-enabled cpu hogging email client, leading to the new systemd libc: " Technically, this move makes perfectly sense, too. We are sick of supporting unstable glibc APIs and ABIs, and we believe that we greatly benefit from the fact that we now finally have everything the OS userspace consists of in one single repository. Of course, this new libc is not available to Ubuntu and other Linux distributions that have not yet adopted systemd. However, after deliberately choosing a home-grown display server (Wayland) over the generally accepted one (Mir) we decided creating an incompatible libc would be the best approach to create a strong platform following a strict release cadence."

On the bright side "We also renamed the API call creat() to create()..."

Wayland/Weston Gets Forked As Northfield/Norwood 252

Posted by timothy
from the same-number-syllables dept.
An anonymous reader writes "Weeks after Canonical announced Mir, Wayland's display server protocol and Weston compositor have been forked. A contributor to Wayland found differing views with the project over desktop eye candy and other technical decisions to the X11 successor, which resulted in forming the Northfield and Norwood projects. The developer, Scott Moreau, has been outted from the project but has provided a lengthy explanation why the fork was needed to advance the Linux desktop."

ZFS Hits an Important Milestone, Version 0.6.1 Released 99

Posted by samzenpus
from the brand-new dept.
sfcrazy writes "ZFS on Linux has reached what Brian Behlendorf calls an important milestone with the official 0.6.1 release. Version 0.6.1 not only brings the usual bug fixes but also introduces a new property called 'snapdev.' Brian explains, 'The snapdev property was introduced to control the visibility of zvol snapshot devices and may be set to either visible or hidden. When set to hidden, which is the default, zvol snapshot devices will not be created under /dev/. To gain access to these devices the property must be set to visible. This behavior is analogous to the existing snapdir property.'"

Uniloc Patent Case Against Rackspace Tossed for Bogus Patents 76

Posted by Unknown Lamer
from the don't-mess-with-red-hat dept.
netbuzz writes "A federal judge in Texas, presiding over a district notorious for favoring patent trolls, has summarily dismissed all claims relating to a case brought by Uniloc USA against Rackspace for [Linux] allegedly infringing upon [Uniloc's] patents. Red Hat defended Rackspace in the matter and issued a press release saying: 'In dismissing the case, Chief Judge Leonard Davis found that Uniloc's claim was unpatentable under Supreme Court case law that prohibits the patenting of mathematical algorithms. This is the first reported instance in which the Eastern District of Texas has granted an early motion to dismiss finding a patent invalid because it claimed unpatentable subject matter.'" You can't patent floating point math after all.

Spanish Open Source Group Files Complaint Over Microsoft Use of UEFI Secure Boot 154

Posted by Soulskill
from the saga-continues dept.
sl4shd0rk writes "Hispalinux, which represents Spanish Open Source developers and users, has filed a complaint against Microsoft with the European Commission. 14 pages of grief cited Windows 8 as an 'obstruction mechanism' calling UEFI Secure Boot a 'de facto technological jail for computer booting systems... making Microsoft's Windows platform less neutral than ever.' On March 6 of 2012 the Commission fined Microsoft 561 million Euros for failing to offer users a choice of web browser, and there was also a 2004 ruling which found the company had abused its market position by tying Windows Media Player to Windows itself. Relations appear to remain more tense towards Windows in Europe, so there may be some hope of making UEFI more Linux-friendly. UEFI has been implicated in the death of Samsung laptops running Linux."

The End Is Nigh For the Linux Game Tome 123

Posted by Unknown Lamer
from the end-of-an-era dept.
First time accepted submitter Sodki writes "The Linux Game Tome, one of the most important websites related to video gaming in GNU/Linux, will shut down on the 13th of April, according to a news post published on the website. The decision was made due to the 'lack both the time and the ambition to do what is necessary to keep the site afloat,' which has resulted in 'spam clogging the forums, lack of updates and increasing brokenness of the site.' This might not be the end, though. The maintainers of The Linux Game Tome will make available a dump of the games database, so that anyone interested can cook up a new and updated version of the website, and a worthwhile effort will be considered for a transfer of ownership of the domain. The current source code of the website, which is from 1999, will not be available because 'it is not fit for human consumption.'" It certainly had a good run; I remember poking around the Linux Game Tome as a teenager in the misty past (and it's where I discovered Freeciv, Warzone 2100, and lbreakout2). Are there any alternatives already operating (unfortunately, Freecode doesn't seem popular with game authors)? Or: Which one of you is going to write the Linux Game Tome 3.0?

Matthew Garrett Has a Fix To Prevent Bricked UEFI Linux Laptops 74

from the and-it-can-be-yours-for-free dept.
hypnosec writes "UEFI guru Matthew Garrett, who cleared the Linux kernel in Samsung laptop bricking issues, has come to rescue beleaguered users by offering a survival guide enabling them to avoid similar issues. According to Garrett, storage space constraints in UEFI storage variables is the reason Samsung laptops end up bricking themselves. Garrett said that if the storage space utilized by the UEFI firmware is more than 50 percent full, the laptop will refuse to start and ends up being bricked. To prevent this from happening, he has provided a Kernel patch."

Ask Slashdot: New To Linux; Which Distro? 573

Posted by timothy
from the pick-and-choose dept.
An anonymous reader writes "I'm a very new user to Linux looking for a distro that allows me to control and customize, but I'm not sure where to start. I had a friend install Ubuntu 12.04 on my computer, with the E17 window manager and somehow I managed to crash it during the copying of some non-important files and now my computer won't boot (the hardware's fine though). I've found descriptions of Arch Linux to be spot on to what I'm looking for and want (Slashdot user serviscope_minor mentioned Arch a couple weeks ago and it caught my attention), but my experience in the terminal is literally about an hour. That said, I really want to learn more, don't mind hard work, enjoy challenges, and am perfectly willing to spend hours and hours for months on end to learn command line. Any suggestions, projects to start with, books to read, or tutorials to do to try would be appreciated."

Longest Running Linux Distribution Slackware Adopts MariaDB 109

Posted by timothy
from the onward-and-upward dept.
First time accepted submitter Gerardo Zamudio writes with the news that Ur-distribution Slackware is replacing MySQL with MariaDB. From an update posted to the Slackware news feed yesterday: "This shouldn't really be a surprise on any level. The poll on LQ showed a large majority of our users were in favor of the change. It's my belief that the MariaDB Foundation will do a better job with the code, be more responsive to security concerns, and be more willing to work with the open source community. And while I don't think there is currently any issue with MySQL's licensing of the community edition for commercial uses, several threads on LQ showed that there is confusion about this, whereas with MariaDB the freedom to use the software is quite clear." (Here's a link to the mentioned poll.)

Carewolf writes "Jeff Mitchell writes on his blog about what almost became 'The Great KDE Disaster Of 2013.' It all started as simple update of the root git server and ended up with a corrupt git repository automatically mirrored to every mirror and deleting every copy of most KDE repositories. It ends by discussing what the problem is with git --mirror and how you can avoid similar problems in the future."
