While we've already seen many AVX/AVX2 Linux kernel patches in recent months out of Intel's Open-Source Technology Center, there's still more ahead. The latest patches were published on Wednesday and provide an AVX and AVX2 version of AESNI-GCM encode/decode. Writing the specific code for the Advanced Vector Extensiuons is worthwhile as the reported performance gains can be nearly a 20% speed-up and the beenefits will be even greater on the upcoming Intel Broadwell processors.
The point of a port knock tool is to make TCP servers respond to TCP SYN request only after a pre-defined sequence of packets have been sent and received. It’s like having a club house whose doors open only after a set number and sequence of knocks. There have been tools like in the past, but as far as I know, all have been in user space. Knock is thus likely the first port knock tool for Linux in kernel space.
The article is being quite kind when it calls the possibility of licensing "short-sighted." I think it will anger many Linux users and developers. Whether or not Canonical has the right to do it is totally beside the point. The mere fact they are considering it indicates that the company may have totally lost touch with the true spirit of the open source community.
The pace of development for CentOS can sometimes seem frustratingly slow. But, for an industry that values stability and predictability over access to bleeding edge features, a distribution that’s slow to change is a virtue. So, when CentOS does have an upgrade, it’s definitely worth paying attention to. In the most recent release, there are a number of features that will be of interest to web hosting companies and we are going to have a look at some of the major changes here.
When Andy Rubin left his job heading up Google's Android team earlier this year, it turned out he was heading for an even more droid-like project: robots. Rubin revealed to The New York Times that the Google "moonshot" he's been working on is a robot project.
When the US Federal government shutdown from October 1 - 16 this year, a small Drupal shop in the Washington DC area turned a list of freelance gigs for furloughed employees in a Google doc into a website in five hours. Unfurlough.us went live at 1:00 am EST on October 4, accumulating 50,000 page views in a little over a week.
ownCloud, Inc. is proud to announce today, December 11, that the Community Edition of its highly anticipated ownCloud 6 open source DIY (Do It Yourself) cloud server software is now available for download/upgrade with an improved design.
The MintBox 2 is here, and it’s more powerful than ever. Just how much power are you getting for nearly £400 though?
Valve's Linux-based gaming-centric operating system SteamOS will be with us by the weekend, as the company plans to get the first prototype Steam Machine boxes in front of beta testers tomorrow.
This is my final post in this series about the btrfs filesystem. The first in the series covered btrfs basics, the second was resizing, multiple volumes and devices, the third was RAID and Redundancy,and the fourth and most recent was subvolumes and snapshots.
I think (and hope) that all of those together give a reasonable overview of what the btrfs filesystem is, what you can do with it, and how you can do some of those things. In this post I will wrap up a couple of loose ends - error recovery, and integration with other standard Linux utilities - and try to give a recap of the series as a whole. For complete and authoritative information, please refer to the Btrfs Wiki at kernel.org.
This is the main reason why Windows barely gets a look-in in today's cloud world. When I ask FOSS devops-type colleagues about it, their responses range from incredulity to hilarity. Why on Earth would they want to deploy on Windows? What possible advantage would it give them? These guys wield Puppet and Chef to deploy vast swarms of headless virtual Linux systems. Microsoft and proprietary software doesn't feature in their world; some weirdos run Mac laptops but that's about it.
Valve's Linux-based Steam Machines gaming console starts shipping today to a few beta testers. SteamOS, it's Linux for gamers, is scheduled to be released to everyone at the same time.
