Facebook engineer Chris Mason is unequivocal about the primacy of Linux in Facebook’s storage infrastructure.

“If it runs on a computer, and it’s storing important data,” he said, “it’s running Linux.”

Mason, speaking at the Linux Enterprise End-User Summit on Monday in New York, joined Facebook just six months ago in order to spearhead the social network’s move to btrfs (usually pronounced “butter eff ess.”), the Linux-based file system that he created in 2008 while working at Oracle.

The People Who Support Linux: Systems Engineer Teaching Himself Python

Filed under
GNU
Linux

Systems engineer Renault Ellis started using Linux five years ago when he was enrolled in a security and forensics program. He was studying IP tables and read the C Programming Language manual by Ken Thompson and Dennis Ritchie along with Cliff Stoll’s The Cuckoo’s Egg.

“I was hooked,” Ellis said via email. “I knew then I wanted to be a Linux Engineer.”

Ellis is now a Senior Linux and Unix Engineer at electronics distributor Premier Farnell in Chicago, Illinois, where he creates, tests and deploys scripts in an eCommerce environment. He works with Apache and several different monitoring tools, both open source and commercial, and leads a lot of the DR (disaster recovery) and PCI (payment card industry) processes in their Unix environment.

During the Big Buck Bunny video playback process, the CPU usage was monitored by the test profile and we also monitored each graphics card's GPU temperature, GPU usage, and the overall AC system power draw (via a WattsUp power meter). The additional sensors can be polled automatically by the Phoronix Test Suite by setting the MONITOR=gpu.usage,gpu.temp,sys.power environment variable. This testing is quite straight forward and mainly intended for reference purposes for those thinking about a NVIDIA GPU for a Linux HTPC / multimedia PC, so let's get straight to the data.

Makulu Linux 6.0 KDE: Guaranteed to make you smile

Filed under
GNU
Linux
Reviews

Another Makulu Linux distribution was released today, and that's always good news! This time it is the KDE desktop for the Makulu 6.x series. The Xfce version of this was just released a couple of weeks ago, so i don't exptect for there to be any major surprised: I hope that means this will not be a very lengthy post.

As usual, the release announcement gives a good overview of the what and why in this release. The most important specifics are that it is built on Linux kernel 3.14.7 and KDE SC 4.13.1. The download images are available from the Makulu Linux KDE page, it is a 32-bit (i686) build that is approximately 1.7GB in size. It is a hybrid ISO, so you can burn it to disk or dump it with dd to a USB stick, and it does not support UEFI boot.

Peppermint Five Is a Very Light and Interesting OS Based on Ubuntu 14.04 LTS

Filed under
OS
Ubuntu

This latest iteration of Peppermint was released a year ago and, back then, it was using Ubuntu 13.04. The developers have moved up from that version and they are now using Ubuntu 14.04, which is the latest LTS released by Canonical.

Future Peppermint users will benefit from this decision made by the developers because it means that the support period for the OS will most likely coincide with the one for Ubuntu, which is five years.

At the invitation only Linux Enterprise End-User Summit held at the Convene Center Financial District, Jim Zemlin, the Linux Foundation's executive director, told an audience of several hundred Wall Street executives and top Linux developers what he sees as the future of technology.

If the combination of Wall Street bears and bulls and Linux programmers seems odd, then you haven't been paying attention. The New York Stock Exchange, New York Mercantile Exchange, and NASDAQ all run on Linux. Indeed, almost all stock exchanges now rely on Linux.

Red Hat CEO Jim Whitehurst: No One Knows OpenStack Better Than Us

OSS

Jim Whitehurst, CEO of Red Hat believes the wait should be over. In a phone conversation over a two-day period following Red Hat's earnings report last week, Whitehurst assured me his company has a stacked deck in that all-important new frontier known as OpenStack. With the sort of confidence you would expect for someone of Whitehurst's pedigree, he proclaimed "no one knows OpenStack better than us." Investors and analysts have no reason to doubt him.
Whitehurst believes his company has an added advantage -- not only from its long history of open source expertise, but he believes very few players actually understand what OpenStack is. He explained that some make the mistake of confusing OpenStack's relationship to the cloud and server virtualization. In other words, having a cluster of virtualized servers does not qualify as a legitimate cloud platform.
Whitehurst envisions OpenStack as the "default choice for next-generation architecture." He does not see a scenario where "Red Hat does not emerge as the leader." He described this as "his mission."
