KernelCare: New no-reboot Linux patching system

On a well-maintained Linux system, months can go by without needing to reboot. Sooner or later, however, a security patch to the Linux kernel will require you to reboot your machine. That’s not a real problem on a desktop, but when you’re talking hundreds of servers it can be a real pain. That’s where CloudLinux’s new program KernelCare comes in.
KernelCare

CloudLinux, makers of the CentOS-related CloudLinux OS, a Linux distribution for hosting providers, claims that with KernelCare, scheduled outages for security patches on Linux servers are now a thing of the past, giving organizations real-time updates. The program automatically applies Linux server security updates without having to re-boot. This frees technical personnel from the laborious process that takes several minutes for every server, several times a year.

Linux viewed as XP replacement

Computer users on the defunct Windows XP do not have to buy costly upgrades to bolster their security but can download an alternative program for free, a computer expert has said.
Microsoft retired the Windows XP operating system last month which made the software unsupported and open to viruses and cyber attacks.
St Luke’s Church Reverend Derek Harding, who has more than 30 years experience working in the IT industry in Europe, said the Linux program was free and proved to be more secure than Windows 7.
However, BP Computers operational manager Brad Clark said Linux was not mainstream and would frustrate computer users that weren’t technically savvy.
Small business and home computer users on XP who used their computer for security related tasks such as emailing or internet banking were no longer secure after April 8.
Harding said the free Linux system which is popular in America, Europe and China looks similar to Windows and can be used for security related tasks.
The most common version, Linux Mint, can be downloaded from linuxmint.com .

Linux games will load much faster thanks to Valve sponsorship

Valve has a vested interest in not only getting as many games working under Linux as possible, but also making them look as good and run as fast as their Windows equivalents. In order to do that, Valve has seen fit to fund projects that improve the underlying tech those games run on.
With that in mind, Valve has sponsored some optimization work on the Mesa 3D Graphics Library–a collection of open source libraries that allow hardware accelerated 3D graphics and OpenGL to work effectively on Linux. Linux gamers will be pleased to know that the work specifically targeted the load times of games. Those times are being cut significantly by improving the shader compilation process by taking advantage of threaded compiling and lazy shader reflection (features Direct3D has had for a while).
What this means in reality is much faster load times, with the example given being DOTA 2 launching 20 seconds faster on a Gigabyte Brix Pro machine. That’s a Core i7 machine using Intel’s Iris Pro 5200 GPU. The improvements will be applicable to many games, but Counter-Strike: Global Offensive is specifically mentioned alongside DOTA 2, a game that hasn’t been officially announced for release on Linux yet.

Ubuntu for Android is dead

The Ubuntu for Android project was launched in early 2012 with the aim to merge Android Mobile and Ubuntu Linux desktop. According to Canonical, the project has been shelved for now and is not under active development.
Ubuntu for Android was an innovative project which would allow Android Mobile users to dock their smartphones to desktop, and boot up Ubuntu Linux from the device making the setup a full fledged Ubuntu PC. The data would be stored on the smartphone and shared between both the operating systems.

Raspberry Pi Cookbook

A cookbook for raspberry pie – what could be more logical? But only if you spell it Raspberry Pi.
Raspberry Pi is the computing sensation of the decade. It is small, cheap and capable of being used for general purpose tasks as well as embedded computing. It isn’t quite disposable computing but it gets very close.
In principle it is just a Linux ARM based computer and as such it probably doesn’t need a book dedicated to it, but not everyone knows Linux. What is more not everyone who knows Linux knows about the Linux software that lets you get access to the Raspberry Pi’s special hardware. What this means is that even an expert can find themselves wondering how to do some task or other. One alternative is to look it up on the web and, given the size of the Raspberry Pi community, this often works, but the information you find can be of variable quality in terms of both its presentation and how fresh it is. Another alternative is to buy a copy of this cookbook which provides information in a “you want to do this – then read this” sort of format.

Why the operating system still (kind of) matters

Canonical founder Mark Shuttleworth has been beating the Linux drum for years — particularly around the Ubuntu distribution that Canonical develops and supports — but his message, and that of much of the Linux community, has taken more of an OpenStack tone lately. Shuttleworth came on the Structure Show podcast this week to tell us when Linux still matters and when it’s the cloud — OpenStack, Amazon Web Services or otherwise — that’s driving the ship in IT.
It was a wide-ranging interview, covering everything from Shuttleworth’s space trip to how Canonical makes money, and the whole thing is well worth a listen. But here are the highlights. And, of course, anyone really interested in learning about how the software that powers cloud computing will evolve should come to our Structure conference June 18 and 19 in San Francisco.

Unreal Engine update 4.1 adds Linux-Steam OS support

The first major update for the Unreal Engine 4 has arrived hot on the heels of its debut at GDC2014, a little over a month ago. Unreal Engine version 4.1 is now available for subscribers to download and now fully supports several new game platforms including Linux-SteamOS, PlayStation 4 and Xbox One.
The UE4.1 update will make it easier for new developers to secure a license as Epic is offering UE4’s complete source code, at no additional cost, directly to registered PlayStation developers and ID@Xbox members. This was not supplied in the initial release due to restrictions set by the console manufacturers but both Sony and Microsoft are said to be validating the engine now. Furthermore UE4-based titles can now be submitted before the validation process is complete.
Version 4.1 will also provides refinements to workflow for iOS and Android platforms, new templates for both C++ and Blueprint visual scripting projects, over 100 improvements based on community feedback and support for Linux (which includes the Linux-based SteamOS). The support for Steam OS and Linux will make it easier and quicker for developers to port completed games to the open-source platforms, however it will still require a Windows or Mac machine to run the actual development kit and a Steam Controller to test the finished product.

Linux Foundation responds to Heartbleed with Core Infrastructure Initiative

The Core Infrastructure Initiative (CII) is the software industry’s response to the Heartbleed vulnerability. I read OpenSSL Foundation president Steve Marquess’s recent blog post before the announcement of the CII that explained that his foundation typically received a meager $2,000 per year in donations and maybe as much as a $1 million per year in support contracts. I really hope the half-million sites that use OpenSSL would get out their checkbooks and donate to pay for independent pen testing and code reviews.
