6 RFCs for understanding how the internet works

Friday 6th of July 2018 07:02:00 AM

Reading the source is an important part of open source software. It means users have the ability to look at the code and see what it does.

But "read the source" doesn't apply only to code. Understanding the standards the code implements can be just as important. These standards are codified in documents called "Requests for Comments" (RFCs) published by the Internet Engineering Task Force (IETF). Thousands of RFCs have been published over the years, so we collected a few that our contributors consider must-reads.

Wallabag: An open source alternative to Pocket

Friday 6th of July 2018 07:01:00 AM

5 military phrases for DevOps practitioners

Thursday 5th of July 2018 07:01:00 AM

The U.S. military is known for quite a few things, including its excessive and fascinating use of acronyms, euphemisms, and colorful phrases to describe certain situations. But many of these terms are applicable to other areas of life, including many non-military jobs.

Following are five phrases from the armed forces that I think DevOps practitioners should adopt.

Open source money: Bitcoin, blockchain, and free software

10 killer tools for the admin in a hurry

Tuesday 3rd of July 2018 07:02:00 AM

Administering networks and systems can get very stressful when the workload piles up. Nobody really appreciates how long anything takes, and everyone wants their specific thing done yesterday.

So it's no wonder so many of us are drawn to the open source spirit of figuring out what works and sharing it with everyone. Because, when deadlines are looming, and there just aren't enough hours in the day, it really helps if you can just find free answers you can implement immediately.

How to make a career move from proprietary to open source technology

Tuesday 3rd of July 2018 07:01:00 AM

I started my journey as a software engineer at Northern Telecom, where I developed proprietary software for carrier-grade telephone switches. Although I learned Pascal while in college, at Northern Telecom I was trained in a proprietary programming language based on C. I also used a proprietary operating system and a proprietary version-control software.

What Game of Thrones teaches us about working openly

Tuesday 3rd of July 2018 07:00:00 AM

You might think the only synergy one can find in Game of Thrones is that between Jaime Lannister and his sister, Cersei. Characters in the show's rotating cast don't see many long term relationships, as they're killed off, betrayed, and otherwise trading loyalty in an effort to stay alive. Even the Stark children, siblings suffering from the deaths of their parents, don't really get along most of the time.

My first sysadmin mistake

Monday 2nd of July 2018 07:01:00 AM

If you work in IT, you know that things never go completely as you think they will. At some point, you'll hit an error or something will go wrong, and you'll end up having to fix things. That's the job of a systems administrator.

As humans, we all make mistakes. Sometimes, we are the error in the process, or we are what went wrong. As a result, we end up having to fix our own mistakes. That happens. We all make mistakes, typos, or errors.

An insider's look at drafting the GPLv3 license

Friday 29th of June 2018 07:01:00 AM

Last year, I missed the opportunity to write about the 10th anniversary of GPLv3, the third version of the GNU General Public License. GPLv3 was officially released by the Free Software Foundation (FSF) on June 29, 2007—better known in technology history as the date Apple launched the iPhone. Now, one year later, I feel some retrospection on GPLv3 is due. For me, much of what is interesting about GPLv3 goes back somewhat further than 11 years, to the public drafting process in which I was an active participant.

GameMode 1.2 adds configuration options about the default and desired governors, now supports soft real-time scheduling on kernels with SCHED_ISO support and will then use renice to boost games to a higher priority, the GameMode service is now D-Bus activated than needing to be explicitly enabled by systemd, and the GameMode libraries are now properly versioned.

After a period of beta testing, it’s nearly ready to roll out on PC, Mac, and Linux. While it probably isn’t going to look a lot different from the beta that’s currently available, this is exciting news for more reasons than one.

Jonathan Dieter: Small file performance on distributed filesystems - Round 2

Last year, I ran some benchmarks on the GlusterFS, CephFS and LizardFS distributed filesystems, with some interesting results. I had a request to redo the test after a LizardFS RC was released with a FUSE3 client, since it is supposed to give better small file performance. I did have a request last time to include RozoFS, but, after a brief glance at the documentation, it looks like it requires a minimum of four servers, and I only had three available. I also looked at OrangeFS (originally PVFS2), but it doesn’t seem to provide replication, and, in preliminary testing, it was over ten times slower than the alternatives. NFS was tested and its results are included as a baseline. I once again used compilebench, which was designed to emulate real-life disk usage by creating a kernel tree, reading all the files in the tree, simulating a compile of the tree, running make clean, and finally deleting the tree. The test was much the same as last time, but with one important difference. Last time, the clients were running on the same machines that were running the servers. LizardFS benefited hugely from this as it has a “prefer local chunkserver” feature that will skip the network completely if there’s a copy on the local server. This time around, the clients were run on completely separate machines from the servers, which removed that advantage for LizardFS, but which I believe is a better reflection on how distributed filesystems are generally used. I would like to quickly note that there was very little speed difference between LizardFS’s FUSE2 and FUSE3 clients. The numbers included are from the FUSE3 client, but they only differed by a few percentage points from the FUSE2 client. Read more

GNOME 3.30 Desktop Environment to Enter Beta on August 1, GNOME 3.29.4 Is Out

With a two-day delay, the GNOME Project through Javier Jardón announced today the release of the fourth and last development snapshot of the GNOME 3.30 desktop environment before it enters beta testing next month, GNOME 3.29.4, which continues to add improvements to various of GNOME's core components and applications. However, due to the summer vacation and the GUADEC conference, GNOME 3.29.4 isn't a major snapshot as many would have expected. It only adds some minor changes and bug fixes to a handful of components, including GNOME Shell, Mutter, Evolution, GNOME Photos, GNOME Builder, GNOME Online Accounts, Polari, Bijiben, Evince, Epiphany, Baobab, GNOME Control Center, and File Roller.
