Linux, Apache, Perl, X10, Webcams... and Christmas Lights 30

Posted by Unknown Lamer
from the blinkenlights dept.
An anonymous reader writes "Clement Moore writes

'Twas the night before Christmas,
and while not a creature was stirring (not even an optical mouse),
/.'ers were posting & moderating with squeals of delight.
When out on the Internet there arose such a clatter,
I sprang from my keyboard to see what was the matter.
I knew in a moment it must be Alek's Controllable Christmas Lights Webcam.
But remembered in previous years it was a hoax - /. said damn.
And then, in a twinkling, I realize Alek has done it for real — W'OH!
With 20,000 lights plus giant inflatable Elmo, Frosty, Santa, SpongeBob, and Homer Simpson — D'OH!
The X10 controls and 3 live webcams provide such clarity,
that it has raised over $70,000 for Celiac charity.
'Merry Christmas to all, and to all a good night!'"

from the rubber-band-and-russian-accent dept.
beefsack writes "An engineer by the name of Andrej Skraba has combined an Arduino board and an MK802 mini PC running Ubuntu to create a robot which is controllable via its own node.js server and a mobile phone. Seen by some as products competing in a similar space, Andrej shows how the two devices can make the most of their unique features to complement each other, working together."

KDE's Plasma Active Ported To Nexus 7 55

Posted by timothy
from the looking-handy dept.
sfcrazy writes "KDE developers have succeeded in running the touch-optimized Plasma Active Linux Distribution on Nexus 7. Earlier Ubuntu developers managed to create a installer for Nexus 7, but those builds also showed that Unity, in its current form, is not ready for touch-based devices. KDE has an edge here as they have optimized versions for netbooks, desktops and touch-based devices so a user doesn't have to make any compromises as one has to do with other DEs or shells which are focusing more in touch-based devices only." Here are detailed instructions on how to install it.

After 12 years of Development, E17 Is Out 259

Posted by timothy
from the unlimited-power dept.
The Enlightenment front page bears this small announcement: "E17 release HAS HAPPENED!" The release announcement is remarkably spartan — it's mostly a tribute to the dozens of contributors who have worked on the software itself and on translating it into many languages besides system-default English. On the other hand, if you've been waiting since December 2000 for E17 (also known as Enlightenment 0.17), you probably have some idea that Enlightenment is a window manager (or possibly a desktop environment: the developers try to defuse any dispute on that front, but suffice it to say that you can think of it either way), and that the coders are more interested in putting out the software that they consider sufficiently done than in incrementing release numbers. That means they've made some side trips along the way, Knuth-like, to do things like create an entire set of underlying portable libraries. The release candidate changelog of a few days ago gives an idea of the very latest changes, but this overview shows and tells what to expect in E17. If you're among those disappointed in the way some desktop environments have tended toward simplicity at the expense of flexibility, you can be sure that Enlightenment runs the other way: "We don't go quietly into the night and remove options when no one is looking. None of those new big version releases with fanfare and "Hey look! Now with half the options you used to have!". We sneak in when you least expect it and plant a whole forest of new option seeds, watching them spring to life. We nail new options to walls on a regular basis. We bake options-cakes and hand them out at parties. Options are good. Options are awesome. We have lots of them. Spend some quality time getting to know your new garden of options in E17. It may just finally give you the control you have been pining for."

GNU Hands Out Trisquel At a Microsoft Store 274

alexanderb writes "Remember GNU's Windows 8 launch trick or treat in October, where Free Software Foundation activists handed out gratis copies of the free (as in freedom) system Trisquel GNU/Linux? Well, GNU returned for a Microsoft store's 'Tech for Tots' session on December 20th in Boston, MA. Like in October, the activists (accompanied by a gnu) handed out gratis copies of Trisquel GNU/Linux — a free alternative to Microsoft's new operating system, Windows 8."

Learn Linux the Hard Way 185

Posted by Soulskill
from the for-the-really-hard-way-close-your-eyes-first dept.
An anonymous reader writes "Here is a free interactive beta of Learn Linux The Hard Way; a web-based virtual Linux environment which introduces the command line and other essential Linux concepts in 30 exercises. It's written in the style of Zed A. Shaw's Learn Code the Hard Way lessons. The authors says, 'You will encounter many detailed tables containing lists of many fields. You may think you do not need most of this information, but what I am trying to do here is to teach you the right way to approach all this scary data. And this right way is to interpret this data as mathematical formulas, where every single symbol has its meaning.' Of course, my first entry was rm -rf /* which only produced a stream of errors. I wish I had discovered something like a long time ago."

GarageGames Starts IndieGoGo Campaign To Port Torque 3D To Linux 71

Posted by timothy
from the if-you-want-it dept.
Open source (as Torque 3D recently became) is one thing; cross-platform is another. Now, reader iamnothing writes "GarageGames is heading to IndieGoGo to port Torque 3D to Linux. The campaign is centered around hiring a dedicated developer or team to port Torque 3D to Linux. The primary target is Ubuntu 32bit with other flavors of Linux as stretch goals. All work will be done in the public eye under our Github repository under the MIT license."

from the start-playing dept.
New submitter jotaass writes "In news that is guaranteed to make the Linux gaming community (in particular, but not exclusively) excited, Valve has just announced that the Steam for Linux client Beta is now open to the public. A .deb package is available here. Interesting as well, they are using an empty GitHub repository solely as an issue tracker, open for anyone to submit, edit and track bugs, with no actual code in the repo."

sfcrazy writes "Raspberry Pi developer team has introduced the Pi store, a place to get software for Raspberry Pi, in collaboration with IndieCity and Velocix. The team hopes that the store will become a one-stop-shop for Raspbian Pi users. The store already has 23 major applications available for users including LibreOffice and Asterisk. There are classic games like Freeciv and OpenTTD and Raspberry Pi exclusive Iridium Rising. The team also managed to get 'one piece of commercial content: the excellent Storm in a Teacup from Cobra Mobile.'"

Denial-of-Service Attack Found In Btrfs File-System 210

Posted by timothy
from the at-that-range-a-hammer-works-too dept.
An anonymous reader writes "It's been found that the Btrfs file-system is vulnerable to a Hash-DOS attack, a denial-of-service attack caused by hash collisions within the file-system. Two DOS attack vectors were uncovered by Pascal Junod that he described as causing astonishing and unexpected success. It's hoped that the security vulnerability will be fixed for the next Linux kernel release." The article points out that these exploits require local access.

Ask Slashdot: Replacing a TI-84 With Software On a Linux Box? 254

Posted by Soulskill
from the can-we-get-a-modern-display-on-these-things dept.
yanom writes "I'm currently a high school student using my TI-84 for mathematics courses. It has all the functionality I need (except CAS), but saying that the hardware is dated is putting it nicely. Waiting 4-5 seconds for a simple function to be graphed on its 96x64 screen just makes me want to hurl it at the wall. Recently, I've begun to notice the absurdity of doing my math homework on a 70's era microchip when I have an i7 machine with Linux within arm's reach. I've begun looking for software packages that could potentially replace the graphing calculator's functionality, including Xcas and Maxima, but both lack what I consider basic calculator functionality — xcas can't create a table of values for a function, and maxima can't use degrees, only radians. So, does anyone know of a good software package to replace my graphing calculator (and maybe provide CAS to boot)?"

Nokia Abruptly Closes Application Store In China For N9 66

Posted by timothy
from the none-for-you dept.
jppiiroinen writes "It seems that Nokia is slowly killing existing applications for their Linux based N9 mobile phone which are available through their store. As a developer who has published paid (and free) apps, it appears after their final blow of killing the support for paid applications in China, where the main revenue came from, there is not any means to make money, and no reason to maintain apps anymore. What this means also for the end-users: no premium apps, like Angry Birds. There was no heads-up or anything, just a single email without any means to make a complaint. Nokia, So Long, and Thanks for All the Fish." Also being discussed at Maemo.org.

Linux Nukes 386 Support 464

Posted by Unknown Lamer
from the upgrade-time dept.
sfcrazy writes with news that Linus pulled a patch by Ingo Molnar to remove support for the 386 from the kernel. From Ingo's commit log: "Unfortunately there's a nostalgic cost: your old original 386 DX33 system from early 1991 won't be able to boot modern Linux kernels anymore. Sniff." Linus adds: "I'm not sentimental. Good riddance."

That does not compute.
