Ubuntu 15.10 (Wily Werewolf) Is Now Rebased on Linux Kernel 4.2 RC5 According to Mr. Salisbury, the Ubuntu Kernel Team managed to rebase the master-next branch of the anticipated Ubuntu 15.10 (Wily Werewolf) operating system on the upstream Linux 4.2 RC5 kernel, which was just announced by Linus Torvalds this past weekend. “We have rebased our Wily master-next branch to the latest upstream v4.2-rc5 and uploaded to our ~canonical-kernel-team PPA. We are resolving fallout from DKMS packages at this time before we proceed uploading to the archive,” says Joseph Salisbury. Therefore, we can only assume that the final release of the Ubuntu 15.10 (Wily Werewolf) operating system, due for release on October 22, 2015, will be based on the Linux 4.2 kernel series. At the moment, the OS is based on a kernel from the Linux 4.1 LTS series.

However, it doesn't end there. The company has finally made efforts towards improving its drivers for Linux-based systems. Taking TDP out of the equation, driver support and stability have always been two of the issues thrown at AMD graphics cards. The “fabless” chip designer has suffered in the desktop GPU market due to these issues. In fact, many argue that the Fury X's release would have been more successful had AMD shipped it with the Catalyst 15.7 WHQL drivers instead of waiting almost two weeks after the release before updating it. The company, however, seems to have mended its ways and is now extending its efforts towards driver updates not only for Windows but other platforms as well. A recent report from Chris Hoffman of PC World details AMD driver's status for Linux-based systems and the company's endeavor in updating the said drivers. Hoffman noted that AMD currently has two main drivers for Linux: the open-source “Radeon” driver and the closed-source “Catalyst” driver.

Ubuntu 15.10 (Wily Werewolf) est maintenant re-basé sur Linux Kernel 4.2 RC5
Selon M. Salisbury, l'équipe Ubuntu qui s'occupe du noyau a réussi à déplacer la base de la branche maîtresse du prochain système d'exploitation Ubuntu 15.10 (Wily Werewolf) vers la branche amont du noyau Linux 4.2 RC5, qui vient d'être annoncée par Linus Torvalds le week-end dernier.
“Nous avons modifié la base de notre prochaine branche maîtresse vers la toute dernière branche amont v4.2-rc5 et l'avons téléversé sur notre PPA ~canonical-kernel-team. Nous sommes en train de régler les conséquences sur les DKMS en ce moment, avant de procéder à la mise à jour de l'archive”, explique Joseph Salisbury.
Par conséquent, nous ne pouvons que supposer que la version finale du système d'exploitation Ubuntu 15.10 (Wily Werewolf), en raison de sa sortie, le 22 Octobre 2015, sera basé sur la série 4.2 du noyau Linux. Pour l'instant, le système d'exploitation est basé sur un noyau de la série 4.1 Linux LTS.

Nouveaux pilotes Linux pour les cartes graphiques AMD
Advanced Micro Devices (AMD) a récemment publié les pilotes DirectX 12 pour sa gamme de GPU. Mais, il ne s'arrête pas là. L'entreprise a finalement fait les efforts visant à l'amélioration de ses pilotes pour les systèmes basés sur Linux.
Si on excepte TDP, la compatibilité et la stabilité des pilotes ont toujours été les deux questions reprochées aux cartes graphiques AMD. Le concepteur de puces «sans-usine» a souffert sur le marché du GPU de bureau en raison de ces problèmes. En fait, beaucoup estiment que la sortie de la Fury X aurait eu plus de succès si AMD l'avait livré avec les Catalyst 15.7 WHQL au lieu d'attendre près de deux semaines après la sortie pour faire sa mise à jour.
La société, cependant, semble avoir rassemblé ses moyens et étend maintenant ses efforts pour mettre à jour ses pilotes non seulement pour Windows, mais aussi pour d'autres plates-formes
Un rapport récent de Chris Hoffman de PC World détaille l'état des pilotes AMD pour les systèmes basés sur Linux et l'effort de la société pour mettre à jour ces pilotes. Hoffman a noté que AMD a actuellement deux principaux pilotes pour Linux: le pilote open-source «Radeon» et le pilote en source privé «Catalyst».

For Linux, Supercomputers R Us Supercomputers are serious things, called on to do serious computing. They tend to be engaged in serious pursuits like atomic bomb simulations, climate modeling, and high-level physics. Naturally, they cost serious money. At the very top of the latest Top500 supercomputer ranking is the Tianhe-2 supercomputer at China’s National University of Defense Technology. It cost about $390 million to build. But then there’s the supercomputer that Joshua Kiepert, a doctoral student at Boise State’s Electrical and Computer Engineering department, created with Raspberry Pi computers. It cost less than $2,000. No, I’m not making that up. It’s an honest-to-goodness supercomputer made from overclocked 1-GHz Model B Raspberry Pi ARM11 processors with Videocore IV GPUs. Each one comes with 512MB of RAM, a pair of USB ports and a 10/100 BaseT Ethernet port. And what do the Tianhe-2 and the Boise State supercomputer have in common? They both run Linux. As do 486 out of the world’s fastest 500 supercomputers. It’s part of a domination of the category that began over 20 years ago. And now it’s trickling down to built-on-the-cheap supercomputers. Because Kiepert’s machine isn’t the only budget number cruncher out there.

Therefore, we decided to test Mr. Exton's guide on how to install Linux kernel 4.1 LTS on an Ubuntu or Debian GNU/Linux operating system, as well as to post his tutorial here with detailed instructions for anyone to understand them. Before anything else, please note that the following guide is only for 64-bit versions of Ubuntu and Debian. Please also note that the following instructions will replace the current kernel packages of your Ubuntu, Debian, or Linux Mint distributions with “kernel 4.1.0-3-exton,” which is the equivalent version of the official Linux 4.1.3 LTS kernel that can be downloaded from the kernel.org website. It should work for any Ubuntu/Debian-based OS.

Pour Linux, les supercalculateurs R Us
Les supercalculateurs sont des choses sérieuses, appelées à faire de l'informatique sérieuse. Ils ont tendance à être employés dans des activités telles que des simulations sérieuses de bombes atomiques, de modélisation du climat, et de la physique de haut niveau. Naturellement, ils coutent sérieusement de l'argent. Au sommet du dernier classement Top 500 des supercalculateurs se trouve le Tianhe-2 de l'Université Nationale de Technologie de Défense de Chine. Il a couté environ 390 millions de dollars à fabriquer.
Et puis il y a le supercalculateur que Josué Kiepert, un étudiant en doctorat de génie électrique et informatique du département de Boise State, créé avec des cartes Raspberry Pi. Il a coûté moins de 2000 $.
Non, je ne blague pas. C'est un supercalculateur authentique fabriqué à partir de processeurs ARM11 Modèle B du Raspberry Pi surcadencés à 1 GHz avec une GPU VideoCore IV. Chacun est livré avec 512 Mo de RAM, deux ports USB et un port Ethernet 10/100 BaseT.
Et qu'est-ce que le Tianhe-2 et le supercalculateur Boise State ont en commun? Ils tournent tous les deux sous Linux. Comme le font 486 des plus rapides superordinateurs du monde sur 500. Il font partie d'une domination de la catégorie qui a commencé il y a plus de 20 ans. Et maintenant celà ouvre la porte à la construction de supercalculateurs pas chers. Parce que la machine de Kiepert n'est pas la seule à casser du budget.

Plex Media Server 0.9.12.8 Now Has Proper Update for Ubuntu Plex Media Server can be used on a number of platforms, including Linux, Windows, and Mac OS X. It’s capable of connecting lots of smart devices. With the right kind of setup, you can turn almost any PC into a media center. It can even be accessed over the Internet and not online in local networks. According to the changelog, a few regressions in Linux and NAS packaging in 0.9.12.7 have been fixed, the remote access in certain cases involving proxies has been corrected, the web player is now restored on launch if the app was playing when page was reloaded/closed, deleting media files moves them to trash, the upgrade system now works again properly for Drobo, Thecus, Ubuntu and other platforms, a case where hitting the APPLY button showed no remote access incorrectly was solved, and the enable / disable buttons in Remote Access are now much more visible.

His joy of seeing a large number of developers pushing patches quickly turned to anger when RC5 also proved to be bigger than he expected. RC5 is usually passed at the halfway point in the cycle, so it's easy to understand why Linus doesn't like big changes so late. It takes time to test everything and to determine if a release is stable. That means that activity on the developing front must slow down towards the end. Fortunately, Linus seems to be happy again, so it must mean that things are going back to normal.

Linux Concerns: Convenience vs. Security Once upon a recent time, Linux was more secure than it is today. Only the root user could mount external device, and in many distributions, new users were automatically assigned a few groups that limited the hardware they could access. Distributions followed the principle of least privilege (aka least access), under which users, applications, and devices receive only the access to the system that they absolutely require. Applying least privilege makes for a securer system, which is where Linux gained its reputation. However, a secure system is often an inconvenient system, and hopes of desktop domination put pressure on distributions to match the convenience of Windows. The problem was not so much that increased popularity encourages the writing of viruses and malware as that the hope of popularity encouraged the relaxation of security standards in dozens of little ways. A few changes had mixed results. For example, the rise of Ubuntu introduced the use of sudo, which helps to reduce the amount of time that the root user is logged in. But, as implemented, it can make possible the control of a system from multiple accounts, which means that Ubuntu simultaneously increases and decreases security. More often, though, the changes were in the name of being as convenient as Windows, with the cumulative effect.

LXD is an open-source hypervisor designed specifically for use with containers instead of virtual machines (VMs). Kirkland said, “At Canonical, we've been working on containers in Ubuntu for more than half a decade, providing a home and resources for stewardship and maintenance of the upstream Linux Containers (LXC) project since 2010.” Where Microsoft comes in is as a LXD partner. Microsoft is using LXC with Windows API calls in place of Linux API calls for its Docker containers. LXC is one of the fundamental Linux container technologies, underlying Docker and other important container specifications. LXD runs on top of LXC, and Kirkland said “endows the advantages of a traditional hypervisor into the faster, more efficient world of containers.” Source: http://www.zdnet.com/article/canonical-and-microsoft-working-together-on-containers/ Submitted by: Arnfried Walbrecht

It's clear that Microsoft did something right for a change and that the latest version of the OS is better than the previous releases. This is actually a good thing. What's not great about it is the fact that Windows 10 collects huge amounts of data about your PC and you as a user, and most media outlets seem to think that it's OK and that it's just an evolution of the operating system. From my perspective, it's just another reason to move to Linux. Many journalists have treated Windows 10 with a lot of lenience, to say the least. Many have said that Windows 10 does collect plenty of data, but that it is OK because others are doing it as well and pointed fingers at Google or Facebook. Just because others are doing it doesn't mean that it's OK for everyone involved. It's interesting to see how, in just a couple of years, we've moved from being apprehensive about sharing our personal details online to calling it an evolution.

FreeBSD 10.2 Lands with GNOME 3.14.2 and KDE 4.14.3 Users might forget from time to time that Linux is not the only operating system out there and that BSD is alive and thriving. There are a number of BSD derivatives in production, and FreeBSD is just one of them. Its developers are quite active, and updates are made all the time. To make things even more interesting, FreeBSD comes with support for a large number of platforms, including 64-bit, IA64 (from Intel), PowerPC (older Mac computers), and SPARC64. It takes a lot of work to keep the support going for these platforms, especially since a few of them are no longer in use. The BSD platform is not as strange as it might seem. For example, the FreeBSD operating system can use pretty much the same components as any Linux OS, including stuff like GNOME or KDE, which coincidentally have been updated as well in the repos. “The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 10.2-RELEASE. This is the third release of the stable/10 branch, which improves on the stability of FreeBSD 10.1-RELEASE and introduces some new features,” say the developers in the official announcement. According to the changelog, resolvconf has been upgraded to version 3.7.0, the NTP suite is now at version 4.2.8p3, and Centos 6 ports are now supported.

And as though to prove its ongoing utility, The Linux Foundation announced it was launching the Open Mainframe Project today, an open source endeavor devoted to helping companies using mainframe computers. The new venture was driven in large part by IBM, a primary supplier of these machines. In fact, it’s not a coincidence that it announced a partnership with Canonical today to build a Linux mainframe running Ubuntu Linux. It may surprise you to learn Linux has been running on mainframes for 15 years, and as Linux usage has grown on mainframes, a community of users has built up. The project is a response to that growing demand, Jim Zemlin, executive director at the Linux Foundation explained in a statement. The idea is that those companies participating in this project can work together, and begin building a set of open source tools and technologies for Linux mainframes, while helping one another overcome common development issues in the same manner as all open source projects. “The Open Mainframe Project gives these customers, vendors and service providers one place to come together,” Ross Mauri, general manager for IBM Systems explained. IBM is sweetening the pot by contributing 250,000 lines of mainframe code to the Linux community.

Linux Mangaka, Ubuntu for Manga and Anime Fans, Drops elementary OS Style for KDE After a single RC (Release Candidate) version, Linux Mangaka Koe is finally here, but with a “big surprise” for all anime and manga fans who used the previous versions of the distribution. The developers decided to drop the elementary OS style in favor of the KDE desktop environment, so the Koe release of Linux Mangaka is now based on Kubuntu 14.04 LTS (Trusty Tahr). “After the success releasing NYU with a lot of passion, we decided to start creating KOE which reached the final stage yesterday,” says Animesoft International. “We beg for your patience at booting, the system has not a boot-logo (to look more intuitive with the KDE desktop) but positively it ships some customization to fit the way as a complete beautiful Operating System made just for you!” Source: http://linux.softpedia.com/blog/linux-mangaka-ubuntu-for-manga-and-anime-fans-drops-elementary-os-style-for-kde-489461.shtml Submitted by: Arnfried Walbrecht Ubuntu Linux is coming to IBM mainframes According to Ross Mauri, IBM's General Manager of System z, and Mark Shuttleworth, Canonical and Ubuntu's founder, this move came about because of customer demand. For over a decade, Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) were the only supported IBM mainframe Linux distributions. As Ubuntu matured, more and more businesses turned to it for the enterprise Linux, and more and more of them wanted it on IBM big iron hardware. In particular, banks wanted Ubuntu there. Soon, financial CIOs will have their wish granted. In an interview Shuttleworth said that Ubuntu Linux will be available on the mainframe by April 2016 in the next long-term support version of Ubuntu: Ubuntu 16.04. Canonical and IBM already took the first move in this direction in late 2014 by bringing Ubuntu to IBM's POWER architecture. Before that, Canonical and IBM almost signed the dotted line to bring Ubuntu to IBM mainframes in 2011 but that deal was never finalized. This time, it's happening.

Linux Foundation announces open source best practices badge programme The Linux Foundation has announced its plans to introduce a new badge programme designed to help identify open source projects that have made security a priority. The new effort, which is part of the Foundation's Core Infrastructure Initiative (CII), aims to identify and fund critical open source projects in need of assistance. “Despite its prevalence, trying to quickly determine the best maintained and most secure open source to use is a complex problem for both seasoned CIOs and nimble developers. The self-assessment, and the badges that will follow, are designed to be a simple, fairly basic way for projects to showcase their commitment to security and quality,” The Linux Foundation said in its statement.

After a number of years of development, the Bcache File System (Bcachefs) “is more or less feature complete – nothing critical should be missing,” wrote project head Kent Overstreet, in an e-mail to the Linux Kernel Mailing List late Thursday. Linux currently has plenty of working file systems, though no one file system seems to be best-suited for all uses. The main goal of Bcachefs is to match the speed of traditional Linux file systems with the advanced scalability and reliability of newer file systems, Overstreet wrote. Although not a sexy technology, file systems provide the interface to the operating system for storing files on a disk. Overstreet is working on the file system on his own time, without outside funding. He is seeking other administrators and developers to test the system and even contribute to its development. Nonetheless, the release of Bcachefs seems to have met with cautious optimism by the Linux professionals on the Hacker News online forum, though one contributor did say of Overstreet that “I hope the guy has a large stash in his bank. File systems take notoriously long to stabilize.” Source: http://www.pcworld.com/article/2974489/ex-google-revs-up-a-new-linux-filesystem.html Submitted by: Arnfried Walbrecht

The New Ubuntu-Supported Video Driver PPA Is Well Received by Community One of the issues with Ubuntu is that it has some pretty out-of-date repositories, and they haven't done anything to fix this until now, although they are working on a new type of packages (Snappy) that should end this problem. Until then, Ubuntu users need to rely on third-party repositories to get all the latest apps and drivers. There were already a few repos that had the latest drivers, but it's always good when you find drivers that are at least partially supported by the distro. Just setting up a PPA with tested drivers was enough to make the community respond. Many users are now happy to see that they find a reliable and always up-to-date driver resource, but it's also helpful for companies.

When designers or developers want something, they just do it. Linux operating systems are very flexible, and you can do pretty much what you want with them. It's not like Windows or Mac OS which doesn't really let users mess with the themes. And we're not even mentioning overall desktop design. The bottom line is that there aren't any Linux concepts because ideas usually turn into reality. This is also the reason why the Ubuntu 16.04 Stupendously Hot Charmander concept made such a big impact. A lot of people like it, but there were a few who didn't really enjoy the flatness or the fact that the regular Ubuntu stuff, like icons, for example, weren't included. In any case, the overall feeling was that the concept has a lot to promise and it looks like it's coming to life.

Linux Machines Produce Easy to Guess Random Numbers In Linux and other UNIX-like operating systems, these random numbers are produced from a set of sources. These sources can be the user's mouse movements, keyboard input, or various hardware-generated activity like disk IO events, signal interrupts and network packet inter-arrival times. This data is fed to the kernel, which allows applications to pull from it whenever they need it, either via the /dev/random or the /dev/urandom files. The difference between these two files is that /dev/random “provides random data that is nearly 100% entropy” but will also “will block until the OS generates more entropy,” while /dev/urandom “will hand out data from its PRNG (Pseudo-Random Numbers Generator) regardless of the amount of entropy in the entropy pool.” This means random numbers with a lesser entropy value will be provided to various services looking for random data, which trying to avoid blockage situations will use /dev/urandom instead of the safer /dev/random file.
