Due to getting errors in /var/log/mistral/executor.log on regular basis attempting to deploy overcloud via TripleO QuickStart. I was just wondering how much can assist KSM&&KSMTUNED to achieve a goal to set up 5 VMs (6.7GB,1 VCPU)running in overcloud and "instack VM" undercloud with 4 VCPUs,8GB RAM and 4GB swap file on 32GB RAM total on VIRTHOST.

We reported the other day that an ancient bug, which existed in the Linux kernel since 2005, was patched in several recent updates, namely Linux kernel 4.8.3, Linux kernel 4.7.9, and Linux kernel 4.4.26 LTS.

Since the first of the month, I've heard colleagues and others report each of the 10 security variants to Murphy's Law listed below. Murphy is not only alive but has been reincarnated.

It's still Sunday in the US, which means that it's time for you to take yet another RC (Release Candidate) milestone of the upcoming Linux 4.9 kernel release for a test drive.

Previously, some experts believed Rowhammer attacks that altered specific pieces of security-sensitive data weren't reliable enough to pose a viable threat because exploits depended on chance hardware faults or advanced memory-management features that could be easily adapted to repel the attacks. Now, an international team of academic researchers is challenging those assumptions by demonstrating a Rowhammer exploit that alters crucial bits of data in a way that completely roots name brand Android devices from LG, Motorola, Samsung, OnePlus, and possibly other manufacturers. An app containing the researchers' rooting exploit requires no user permissions and doesn't rely on any vulnerability in Android to work.

NitroShare is a fantastic tool that allows you to easily share files across a local network. Created to be simple, fast, cross-platform, and open, NitroShare makes the sharing of files between systems and platforms incredibly easy...all without having to bother with Samba or Windows shares.

Debian may not talk a lot about security, but then fish rarely talk about water, either.

Open source depends on a sustainable community to develop code rapidly, debug code effectively, and build out new features. Because community involvement is voluntary, people's skills, levels of involvement, and time commitments can vary. Given the variable nature of these factors, along with the fact that open source often relies on a philosophy of "release early, release often," quality assurance can be become challenging. read more

Argo, a Department of Energy project at Argonne aimed at developing the prototype for an open-source OS that will work on any type of high-performance machine made by any vendor and will allow users to mix and match modular OS components to suit their needs... They’re developing modifications to Linux that will let the OS manage power throughout a high-performance machine.

You know those times when things go wrong on your computer, and it won’t boot, or you can't’ login into your system, or there’s a rootkit messing up your booting or you just want to recover files from a drive.

If you're a Firefox user and you're a little fed up with going to Google Chrome every time in order to watch Netflix on your Linux machine, the good news is since Firefox 49 landed, HTML5 DRM (through the Google Widevine CDM (Content Decryption Manager) plugin) is now supported. Services that use DRM for HTML5 media should now just work, such as Amazon Prime Video. Unfortunately, the Netflix crew haven't 'flicked a switch' yet behind the scenes for Firefox on Linux, meaning if you run Netflix in the Mozilla browser at the moment, you'll likely just come across the old Silverlight error page. But there is a workaround.

The great promise of a global open source software project like OpenStack is that it can bring together the best and the brightest from all around the world to together create something far greater than any one person, company, or nation could do on its own.

The developers of the Debian-based Parsix GNU/Linux operating system proudly announced the availability for download of the first test build of the upcoming Parsix GNU/Linux 8.15 "Nev" release.
