How would you find out how much RAM is free on your Linux desktop? That's a really easy question with a lot of answers—free, any of the implementations of top and Glances all are valid responses.

Capacity and speed requirements keep increasing for networking, but going from where are now to 100G networking isn’t a trivial matter, as Christopher Lameter and Fernando Garcia discussed recently in their LinuxCon Europe talk about the world of 100G networking.

"You only get one chance to make a first impression," the old saying goes. It's cliche, but nevertheless sound, practical advice. In the realm of open source, it can make the difference between a project that succeeds and a project that fails. That's why making a positive first impression when you release a repo to the world is essential—at least if your motivations involve gaining users, building a community of contributors, and attracting valuable feedback. read more

President Donald Trump has named Ajit Pai as the 34th chairman of the Federal Communications Commission... While expected, the appointment aligns with signs that Trump's FCC would roll back Obama-era policies — most notably the 2015 Open Internet Order, which set today's net-neutrality rules.

Brotli is a new open source compression algorithm designed to enable an Internet that's faster for users. Modern web pages can often be made up of dozens of megabytes of HTML, CSS, and JavaScript, and that's before accounting for images, videos, or other large file content, which all makes for hefty downloads. Such loads are why pages are transferred in compressed formats; they significantly reduce the time required between a website visitor requesting a web page and that page appearing fully loaded on the screen and ready for use. read more

The Linux Foundation is hosting a free webinar called “Open Source Strategy for Enterprise IT” on Thursday, Jan. 26 at 10:00 a.m. Pacific time. In this webinar, presented by Bill Weinberg, Sr. Director and Analyst, Open Source Strategy, and Greg Olson, Sr. Director, Open Source Consulting Services

Google will bring its AI and machine learning technology to the Raspberry Pi this year, and has posted a survey seeking input. Google is planning to deliver tools for the Raspberry Pi later this year built around its artificial intelligence and machine learning technology, according to a Raspberry Pi Foundation blog entry. The announcement links […]

Continuing with our discussion on the command line navigation aspects, in this tutorial, we'll discuss the CDPATH environment variable through easy to understand examples. We'll also discuss some advance details related to this variable.

Axiomtek’s DIN-rail ready “ICO100-839” IoT controller offers an Atom x5-E3930, 8-bit DIO, mini-PCIe, mSATA, extended temp support, and a compact footprint. The ICO100-839 is one of the first embedded computers to use Intel’s recent “Apollo Lake” generation of 14nm-fabricated Atom SoCs. Like the Advantech UTX-3117, the fanless ICO100-839 is referred to as an IoT gateway, […]

Today is Community Manager Appreciation Day. Now, I have to admit, I don't usually partake in the day all that much. The skeptic in me thinks doing so could be a little self-indulgent and the optimist thinks that we should appreciate great community leaders every day, not merely one day a year. Regardless, in respect of the occasion, I want to delve a little into why I think this work is so important, particularly in the way it empowers people from all walks of life. read more

Building your IT infrastructure is often a complicated dance of negotiating conflicting needs. Engineers have ideas of cool things they want to build. Operations wants stability, security, easy maintenance, and scalability. Users wants things to work with no backtalk. In his talk at MesosCon Asia 2016, Frans van Rooyen of Adobe shares his team's experiences with adapting Apache Mesos and Apache DC/OS to support deploying infrastructure to multiple diverse clouds.

In Getting started with shell scripting, I covered the basics of shell scripting by creating a pretty handy "despacer" script to remove bothersome spaces from file names. Now I'll expand that idea to an application that can swap out other characters, too. This introduces the shift method of parsing options as well as creating custom functions. read more

I was doing some work in the yard and I wanted to know the smallest circle that would fit around a 4x6 inch post. Of course, just as a 2x4 is not 2 inches by 4 inches, a 4x6 post (what they call its "nominal" dimensions) is actually 3.5 inches by 5.5 inches, so this smallest circle has as its diameter the diagonal of that 3.5x5.5-inch rectangle. Pythagoras tells us that will be the square root of the sum of 3.5 squared and 5.5 squared. At the time, I only had my cell phone, which has a calculator with only basic math operations, so how do you get the square root of 42.5? read more

Levison said the new version of Lavabit would be built around the Dark Internet Mail Environment (DIME) end-to-end encryption standard that he developed thanks to Kickstarter crowdfunding. DIME provides automated and federated encryption capabilities and is designed to work with different service providers, Levison said.

This document gives an overview of how security is designed into Google's technical infrastructure. This global scale infrastructure is designed to provide security through the entire information processing lifecycle at Google.

Linux is arguably the most successful open source project in all of history. The success of the kernel -- and operating systems that use it -- are not due to any one man or woman. Actually, the achievements are thanks to the Linux community. In other words, it is a team effort -- developers, users, and more.
