What's new in Linux 4.4



With 4.4, Linux now offers much improved support for Intel's new Skylake processor family. Intel claims that Skylake has double the performance and triple the battery life of that five-year old laptop still in your bag because it's "good enough." Without deep operating system support, such as Linux now offers, that improved functionality is largely hidden.

The Linux kernel 4.4 also offers better support for ARM's 64-bit processors and Qualcomm's high-bandwidth capable Snapdragon 820. The popular makers' Raspberry Pi system also has better graphics support thanks to a beta Kernel Mode Setting (KMS) driver.

People who run Linux in a virtual machine (VM) will be pleased that the new virtio-gpu driver enables virtualization guests to use the host graphics card efficiently. "In this release, it allows the virtualization guest to use the capabilities of the host GPU to accelerate 3D rendering. In practice, this means that a virtualized Linux guest can run a game while using the host's GPU acceleration. This makes running games on Linux VMs much faster. To use this, you'll need a VM that uses Linux's native VM hypervisor, KVM, and QEMU 2.5."

NEW: Bash Collection - Useful scripts for Linux admins

I've created a new category named "Bash Collection" on the blog for useful and administrative bash scripts. Currently there are two really cool scripts written by myself that helped me a lot in the past.
If you also have some cool and useful scripts, please don't hesitate to share them with the whole Linux Counter community! Just contact info@linuxcounter.net and attach your scripts with some short descriptions on what they do. Thanks!
To see the scripts collection, follow this link.

REFUGEES WELCOME!

Most of you may know that I am from Germany. I want to say, that I am totally shocked about what actually happens here in germany regarding the refugees. It seems that some of us still hasn't learned from the past and from the history. That is very sad and shocking and this is my personal statement about this:
A warm welcome to all refugees! I'm quiet sure, that the time in Germany will be much better and will contain much more hope for you than the last years or months in your own country. Don't be afraid about some xenophobian germans.They are only a very small minority of us and the others of us, the majority is doing everything to protect you from them and to help you.
Remember, the world is not only brown, it is multicolored.

What can you do to help the project?

Oh, there are many things you can do!

Contributing

Everybody is always welcome to contribute! There are several ways to contribute:
You can just only choose one single project (website, lico-update script or android app) and send us a pull request with your fixes. Or you can fork our repositories and take actively part on the development.
If you want to be a fixed member of the development team and willing to do active development and bug fixing, then I also can give you direct access to the repositories.

Sponsoring

Yes, I still need some hardware. You also may be willing to sponsor the project by providing the needed server hardware and bandwidth. You would get an own page with your logo and you company description. And you would get a very valuable backlink in the footer.

Donating

Beside clicking the banners you are also welcome to donate. Please visit the Donation page and choose your preferred method.

Thanks for reading!

Bien utiliser Git merge et rebase

Un git merge ne devrait être utilisé que pour la récupération fonctionnelle, intégrale et finale d’une branche dans une autre, afin de préserver un graphe d’historique sémantiquement cohérent et utile, lequel représente une véritable valeur ajoutée.
Tous les autres cas de figure relèvent du rebase sous toutes ses formes : classique, tri-partite, interactif ou cherry picking.
Dans cet article de fond, nous allons explorer en détail les sémantiques de merge et rebase, apprendre à choisir entre l’un ou l’autre, et donner des clés pour les utiliser au mieux afin d’obtenir un historique impeccable.
