Linux users need to check out their distributions to see if a nasty bug in libgcrypt20 has been patched. The patch, which has landed in Debian and Ubuntu, is to address a side-channel attack published last week.

For David Price, the first steps down the path to embracing openness started with a diagnosis of atrial fibrillation. That diagnosis was a shock, and like many people with medical conditions in the digital age, Price began frequenting online forums for people with his affliction. read more

It feels great to say that KDE has active contributors across the globe. Two KDE contributors recently presented talks in Asia about their work and encouraged new contributors to join us and get started.

By any measure, the rise of open source software as an alternative to the old, proprietary ways has been remarkable. Today, there are tens of millions of libraries hosted at GitHub alone, and the number of major projects is growing rapidly. read more

I started brewing my own beer more than 10 years ago. Like most homebrewers, I started in my kitchen making extract-based brews. This required the least equipment and still resulted in really tasty beer. Eventually I stepped up to all-grain brewing using a big cooler for my mash tun. For several years I was brewing 5 gallons at a time, but brewing 10 gallons takes the same amount of time and effort (and only requires slightly larger equipment), so a few years ago I stepped it up. read more

Off-the-shelf, consumer home automation has fallen into a pretty standard pattern. You have a smart device (like a lightbulb or door lock) that talks to some kind of hub that you put on your network. It communicates with a cloud service owned by the device vendor, and you interface with that service via a mobile app. This provides an easy out-of-the-box experience and lets the vendor iterate on its service both in the cloud and on mobile; however, this model has a lot of weaknesses and is extremely limiting with what it can do. read more

If you use open source software, chances are you'll encounter a .tar file at some point. The open source tar archive utility has been around since 1979, so it is truly ubiquitous in the POSIX world. Its purpose is simple: It takes one or more files and "wraps" them into a self-contained file, called a tape archive because when tar was invented it was used to place data on storage tapes.

In July, we'll kick off our sysadmin series that will focus on helpful tools and tips for working in the field. We're also working on bringing you some interesting projects in home automation. Other series we have our eyes on this year are productivity hacks and UX for open source projects and products.

While working on the Linux command line, you might find yourself in situations where-in you need to display (or even change) the current system time. Not only that, if you work in a team with members in different timezones, you may want to keep yourself updated with time-related information for zones in which other members are sitting. If you're looking for a tool that lets you do all this (and much more), you will be glad to know there exists a command - dubbed date - that does all this.

This series previews the new self-paced Containers for Developers and Quality Assurance (LFS254) training course from The Linux Foundation. In earlier articles, we installed Docker, introduced Docker Machine, performed basic Docker container and image operations, and looked at Dockerfiles and Docker Hub.

We have a little problem on the web right now and I can only see it becoming a larger concern as time goes by: more and more sites are obtaining certificates, vitally important documents needed to deploy HTTPS, but we have no way of protecting ourselves when things go wrong.

The $25 NanoPi Neo Plus2 SBC combines the WiFi, Bluetooth, and 8GB eMMC of the Neo Air with the quad -A53 Allwinner H5 of the Neo2, and boosts RAM to 1GB. Despite bulking up in one dimension to 52 x 40mm, FriendlyElec’s NanoPi Neo Plus2 is still part of the headless, IoT-oriented Neo family, joining the 40 x 40mm, $8 NanoPi Neo, the wireless enabled, $20 NanoPi Neo Air, and the 64-bit $15 NanoPi Neo2.

Logs on your Linux server are crucial to monitoring and troubleshooting. Take a look at what they actually are and how to make the most of them.

'No reason to delay' As anticipated last week, version 4.12 of the Linux kernel landed Sunday amid a storm of … well, placidity, as it happens.…

Hackers have tools that they use to carry out various types of operations. But among them all, the most crucial is the Linux Operating System.

Over the years, Arch Linux has had the misfortune of being maligned as one of the more challenging modern Linux distributions. That’s a shame, because Arch Linux is one of the most solid distributions you’ll find. Nonetheless, new users finding their way over to the official Arch Linux installation guide may choose to return to the likes of Ubuntu or Linux Mint. Now, however, there are other options, due to the release of some very user-friendly takes on the Arch Linux distribution, including Antergos.

In my last few articles, I've been dipping into the waters of "machine learning"—a powerful idea that has been moving steadily into the mainstream of computing, and that has the potential to change lives in numerous ways.
