Linux Played a Vital Role In Discovery of Higgs Boson 299

An anonymous reader writes "Scientific Linux and Ubuntu had a vital role in the discovery of the new boson at CERN. Linux systems are used every day in their analysis, together with hosts of open software, such as ROOT. Linux plays a major role in the running of their networks of computers (in the grid etc.) and it is used for the intensive work in their calculations."

John the Ripper Cracks Slow Hashes On GPU 61

solardiz writes "A new community-enhanced version of John the Ripper adds support for GPUs via CUDA and OpenCL, currently focusing on slow-to-compute hashes and ciphers such as Fedora's and Ubuntu's sha512crypt, OpenBSD's bcrypt, encrypted RAR archives, WiFi WPA-PSK. A 5x speedup over AMD FX-8120 CPU per-chip is achieved for sha512crypt on NVIDIA GTX 570, whereas bcrypt barely reaches the CPU's speed on an AMD Radeon HD 7970 (a high-end GPU). This result reaffirms that bcrypt is a better current choice than sha512crypt (let alone sha256crypt) for operating systems, applications, and websites to move to, unless they already use one of these 'slow' hashes and until a newer/future password hashing method such as one based on the sequential memory-hard functions concept is ready to move to. The same John the Ripper release also happens to add support for cracking of many additional and diverse hash types ranging from IBM RACF's as used on mainframes to Russian GOST and to Drupal 7's as used on popular websites — just to give a few examples — as well as support for Mac OS X keychains, KeePass and Password Safe databases, Office 2007/2010 and ODF documents, Firefox/Thunderbird/SeaMonkey master passwords, more RAR archive kinds, WPA-PSK, VNC and SIP authentication, and it makes greater use of AMD Bulldozer's XOP extensions."

FSF Criticises Ubuntu For Dropping Grub 2 For Secure Boot 296

sfcrazy writes "The Free Software Foundation (FSF) has published a whitepaper suggesting how free operating systems can deal with UEFI secure boot. In the whitepaper, the foundation has criticized the approach Canonical/Ubuntu has taken to deal with the problem. The paper reads: 'It is not too late to change. We urge Ubuntu and Canonical to reverse this decision, and we offer our help in working through any licensing concerns. We also hope that Ubuntu, like Fedora, will actively support users generating and using their own signing keys to run and share any versions of the software, and not require users to install a key from Canonical to get the full benefit of their operating system.'"

Google I/O Day Two 46

Yesterday Timothy was at Google I/O watching the keynote but there is still plenty of announcements on day two. Today's first big theme: Chrome. Tim reports: "Brian Rakowski VP for (and inventor of) Chrome, shows device transferability among devices of tabs, bookmarks, with a multi-part contrived story, looking at his opened tabs from home and work, etc. from a phone running Chrome. Not only can open tabs from there, but (and this is cool), 'we've made sure the back button works as well.' So you can open a page from a different computer, and have the browsing history of that tab as well. This Chrome syncing affects settings, bookmarks, etc. Also, for those transferred tab pages, pre-loading! So when you click on a tab, it's been loading and now should be read, BAM." As before we'll be updating the story live (below the fold) with his updates as they stream in.

Ubuntu Lays Plans For Getting Past UEFI SecureBoot 393

An anonymous reader writes "Canonical has laid out their plans for handling UEFI SecureBoot on Ubuntu Linux. Similar to Red Hat paying Microsoft to get past UEFI restrictions, Canonical does have a private UEFI key. Beyond that they will also be switching from GRUB to the more liberal efilinux bootloader, and only require bootloader binaries be signed — and they want to setup their own signing infrastructure separate from Microsoft."

12-Core ARM Cluster Beats Intel Atom, AMD Fusion 105

An anonymous reader writes "Phoronix constructed a low-cost, low-power 12-core ARM cluster running Ubuntu 12.04 LTS and made out of six PandaBoard ES OMAP4460 dual-core ARMv7 Cortex A9 chips. Their results show the ARM hardware is able to outperform Intel Atom and AMD Fusion processors in performance-per-Watt, except it sharply loses out to the latest-generation Intel Ivy Bridge processors." This cluster offers a commendable re-use of kitchenware. Also, this is a good opportunity to recommend your favorite de-bursting tools for articles spread over too many pages.

Canonical Announces Ubuntu App Showdown 56

alphadogg writes "Linux developers will soon have a chance to compete for prizes of laptops and smartphones, thanks to Canonical's announcement this week of the Ubuntu App Showdown contest. Developers will have from June 18 until July 9 — a total of three weeks — to create an app using Canonical's Quickly development tool, which combines Python and GTK into a single Ubuntu-centric package. The resulting apps will be judged by a five-member panel, with the developers of the top three receiving new Nokia N9 smartphones."

Ubuntu 12.04 Ported To the Allwinner A10 MK802 Mini PC 54

New submitter beefsack writes "Thanks to the strong ARM support in the Ubuntu repositories, Ubuntu, along with Lubuntu and others have been ported to work on the new MK802 mini PC. Performance is very impressive, especially given that Mali GPU driver support in Linux is still lacking features such as hardware video decoding."

Microsoft To Run Linux On Azure 189

snydeq writes "After years of battling Linux as a competitive threat, Microsoft is now offering Linux-based operating systems on its Windows Azure cloud service. The Linux services will go live on Azure at 4 a.m. EDT on Thursday. At that time, the Azure portal will offer a number of Linux distributions, including Suse Linux Enterprise Server 11 SP2, OpenSuse 12.01, CentOS 6.2 and Canonical Ubuntu 12.04. Azure users will be able to choose and deploy a Linux distribution from the Microsoft Windows Azure Image Gallery and be charged on an hourly pay-as-you-go basis."

Red Hat Clarifies Doubts Over UEFI Secure Boot Solution 437

sfcrazy writes "Red Hat's Tim Burke has clarified Fedora/Red Hat's solution to Microsoft's secure boot implementation. He said, 'Some conspiracy theorists bristle at the thought of Red Hat and other Linux distributions using a Microsoft initiated key registration scheme. Suffice it to say that Red Hat would not have endorsed this model if we were not comfortable that it is a good-faith initiative.'" Color me unimpressed, and certainly concerned: "A healthy dynamic of the Linux open source development model is the ability to roll-your-own. For example, users take Fedora and rebuild custom variants to meet personal interest or experiment in new innovations. Such creative individuals can also participate by simply enrolling in the $99 one time fee to license UEFI. For users performing local customization, they will have the ability to self-register their own trusted keys on their own systems at no cost." From what I can tell, the worst fears of the trusted computing initiative are coming true despite any justifications from Red Hat here. Note that the ability to install your owns keys is certainly not a guaranteed right.

Making ZFS and DTrace Work On Ubuntu Linux 137

New submitter Liberum Vir writes "Many of the people that I talk with who use Solaris-like systems mention ZFS and DTrace as the reasons they simply cannot move to Linux. So, I set out to discover how to make these two technologies work on the latest LTS release of Ubuntu. It turned out to be much easier than I expected. The ports of these technologies have come a long way. If you or someone you know is addicted to a Solaris-like system because of ZFS and DTrace, please, inquire within."

Linux Mint 13 (Maya) Has Arrived 216

New submitter OceanMan7 writes "Linux Mint 13 (Maya) has just been released. DVDs come in four flavors — MATE (with and without codecs) and Cinnamon (with and without codecs) — in both 32-bit and 64-bit versions. The codec-free versions comply with U.S. and Japanese IP regulations. MATE 1.2 is Linux Mint's community-powered extension of Gnome 2. Cinnamon 1.4 is built upon Gnome 3, but has a more traditional look and feel. As with Ubuntu 12.04, upon which Linux Mint draws, all editions come with Long-term support (LTS) until April, 2017. The release notes provide a list of changes.

Ask Slashdot: Temporary Backup Pouch? 153

An anonymous reader writes "It looks simple. I've got a laptop and a USB HDD for backups. With rsync, I only move changes to the USB HDD for subsequent backups. I'd like to move these changes to a more portable USB stick when I'm away, then sync again to the USB HDD when I get home. I figured with the normality of the pieces and the situation, there'd be an app for that, but no luck yet. I'm guessing one could make a hardlink parallel-backup on the laptop at the same time as the USB HDD backup. Then use find to detect changes between it and the actual filesystem when it's time to backup to the USB stick. But there would need to be a way to preserve paths, and a way communicate deletions. So how about it? I'm joe-user with Ubuntu. I even use grsync for rsync. After several evenings of trying to figure this out, all I've got is a much better understanding of what hardlinks are and are not. What do the smart kids do? Three common pieces of hardware, and a simple-looking task."

Google Talks About Its Ubuntu Experience 230

dartttt writes "There was a very interesting session at the Ubuntu Developer Summit by Google developer Thomas Bushnell. He talked about how Ubuntu, its derivatives and Goobuntu (Google's customized Ubuntu based distro) are used by Google developers. He starts by saying 'Precise Rocks,' and that many Google employees use Ubuntu — including managers, software engineers, translators, people who wrote the original Unix, and people who have no clue about Unix. Many developers working on Chrome and Android use Ubuntu. Ubuntu systems at Google are upgraded every LTS release. The entire process of upgrading can take as much as four months, and it is also quite expensive, as one reboot or a small change can cost them as much as a million dollars across the company." Bushnell also mentions that Google Drive will soon be available for Linux. Other news out of UDS: there was discussion of a GNOME flavor of 12.10, Electronic Arts reaffirmed that they "won't delay their Windows work for Linux," and Unity 2D is likely to disappear in 12.10.

Open Source Driver For Microsoft Surface 2.0 31

dartttt writes "Florian Echtler has developed an open-source driver for the Microsoft Surface 2.0 touch screen. According to him, the open source implementation works surprisingly well on Ubuntu 11.10. The process requires you to boot Linux on your Surface 2.0 in the first place. However, it can be done by just booting Ubuntu from a USB hard disk without modify anything on the original Win7 installation."

Dell Designing Developer Oriented Laptop 399

jones_supa writes "Barton George, director of marketing for Dell's Web vertical reveals information about 'Project Sputnik', a laptop tailored for developer needs in web companies. 'We want to find ways to make the developer experience as powerful and simple as possible. And what better way to do that than beginning with a laptop that is both highly mobile and extremely stylish, running the 12.04 LTS release of Ubuntu Linux,' George ponders. He also gives a quick list of packages that the default installation could include. The machine will base on the XPS13, assessing a couple of its main hardware deficiencies along the way." According to the article, this is a "6 month project to investigate an Ubuntu laptop. If successful, we have big plans for the effort." It's unclear how closely they are working with upstream, but there's mention of Canonical as a commercial partner so this may mean Dell is working to ensure some of their hardware Just Works (tm) with Ubuntu. The software side is so far just a customized install with developer tools preinstalled. Ars remains skeptical about Dell's strategy for GNU/Linux support, which may be warranted given their track record.
