• When should you open source your software?

  It’s 20 years this this since the term ‘Open Source’ was coined. In that time the movement for free and open software has gone from a niche to a common method of distribution and a normal way of operating for businesses.

  Major technology shifts are now driven by open source technologies: Big Data (Hadoop, Spark), AI (TensorFlow, Caffe), and Containers (Docker, Kubernetes) are all open projects. Massive companies including Google, Facebook, and even Lyft regularly release Open Source tools for the world to use. Microsoft – whose former CEO once described Linux as a cancer – now embraces the concept.

• Devhelp news

  For more context, I started to contribute to Devhelp in 2015 to fix some annoying bugs (it’s an application that I use almost every day). Then I got hooked, I contributed more, became a co-maintainer last year, etc. Devhelp is a nice little project, I would like it to be better known and used more outside of GNOME development, for example for the Linux kernel now that they have a good API documentation infrastructure (it’s just a matter of generating *.devhelp2 index files alongside the HTML pages).

In my short time working for Clarkson University, I've realized what a huge impact this small university is making on the open source world. Our 4,300 student-strong science and technology-focused institution, located just south of the Canadian border in Potsdam, New York, hosts the Clarkson Open Source Institute (COSI), dedicated to promoting open source software and providing equipment and support for student projects.

While many universities offer opportunities for students to get involved in open source projects, it's rare to have an entire institute dedicated to promoting open source development. COSI is part of Clarkson's Applied Computer Science Labs within the computer science department. It, along with the Internet Teaching Lab and the Virtual Reality Lab, is run by students (supported by faculty advisers), allowing them to gain experience in managing both facilities and projects while still undergraduates.

So rc2 is out, and things look fairly normal.

The diff looks a bit unusual, with the tools subdirectory dominating,
with 30%+ of the whole diff. Mostly perf and test scripts.

But if you ignore that, the rest looks fairly usual. Arch updates
(s390 and x86 dominate) and drivers (networking, gpu, HID, mmc, misc)
are the bulk of it, with misc other changes all over (filesystems,
core kernel, networking, docs).

We've still got some known fallout from the merge window, but it
shouldn't affect most normal configurations, so go out and test.

Chakra is an unusual distribution for a few reasons. It is a rare semi-rolling project, which tries to maintain a fairly stable base system while providing up to date applications. This is an interesting compromise between full rolling and static operating systems. The semi-rolling concept is an idea I like and I was curious to see how well the approach would work dealing with around six months of updates. I was pleased to find Chakra handled the massive upgrade well.

Chakra was once also considered unusual for being very KDE-focused. There are more KDE distribution these days (KaOS, Kubuntu and KDE neon come readily to mind) and I think Chakra may have lost some of its appeal as more competition has established itself in the KDE-centric arena.

I found the distribution to be easy to set up and pretty straight forward to use, but there were a few characteristics which bothered me during my trial with Chakra. One was that while updates installed cleanly, once Plasma 5.12 was installed, I experienced slow login times and reduced performance on the desktop. It could be argued that this is a Plasma problem, not a Chakra problem, but the distribution's rolling release nature means any regressions in new versions of software end up in the user's lap.

Something that tends to bother me about distributions which focus on one desktop toolkit or another is that this approach to selecting software means we are sometimes using less capable tools in the name of toolkit purity. This is not a trade-off I like as I'd rather be using more polished applications over ones which a particular affiliation.

Finally, Chakra includes a number of command line aliases which got in my way. This seems to be a problem I have been running into more often recently. Developers are trying to be helpful by aliasing common commands, but it means that for some tasks I need to change my habits or undefine the provided aliases and the feature ends up being a nuisance instead of a convenience.

Chakra seems to be a capable and useful distribution and I am sure there are people who will appreciate the rolling release nature. Many people will likely also like having lots of KDE applications, and I can see the appeal of this combination. However, one thing which makes me hesitate to recommend Chakra is that the distribution does not appear to bring any special features to the ecosystem. It's a useful operating system and, to be completely fair, users can install non-KDE alternatives if they want to use LibreOffice instead of Calligra or GIMP instead of KolourPaint. But I'm not sure Chakra brings anything unique which makes it stand apart from openSUSE's Tumbleweed or KaOS's polished Plasma offering. Chakra used to be special in its semi-rolling, KDE-focused niche, but these days the distribution has a more competition and I'm not sure the project has any special sauce to set it apart from the crowd.

Back in February, some commits to the Chromium codebase revealed that Chrome OS would soon run Linux applications using a container. While it has been possible for years to run Linux applications on top of Chrome OS using crouton, it's a hacky solution that only works in Developer Mode. Google's solution would presumably work better, and perhaps not require Dev Mode to be enabled.

Let's cut to the chase. Android is the most popular of all Linux distributions. Period. End of statement. But that's not the entire story.

Still it must be said, according to StatCounter, Android is the most popular of all operating systems. By a score of 39.49 percent to 36.63 percent, Android beats out Windows for global personal device supremacy. Sorry Windows, you had a nice run, but between your smartphone failures and the PC decline, your day is done.

But, setting Android aside, what's the most popular Linux? It's impossible to work that out. The website-based analysis tools, such as those used by StatCounter, NetMarketShare, and the Federal government's Digital Analytics Program (DAP), can't tell the difference between Fedora, openSUSE, and Ubuntu.

DAP does give one insightful measurement the others sites don't give us. While not nearly as popular as Android, Chrome OS is more popular than all the other Linux-based desktops combined by a score, in April 2018, of 1.3 percent to 0.6 percent of end users.

With this week's Ryzen 5 2600X + Ryzen 7 2700X benchmarks some thought the CPUFreq scaling driver or rather its governors may have been limiting the performance of these Zen+ CPUs, so I ran some additional benchmarks this weekend.

Those launch-day Ryzen 5 2600X / Ryzen 7 2700X Ubuntu Linux benchmarks were using the "performance" governor, but some have alleged that the performance governor may now actually hurt AMD systems... Ondemand, of course, is the default CPUFreq governor on Ubuntu and most other Linux distributions. Some also have said the "schedutil" governor that makes use of the kernel's scheduler utilization data may do better on AMD. So I ran some extra benchmarks while changing between CPUFreq's ondemand (default), performance (normally the best for performance, and what was used in our CPU tests), schedutil (the newest option), and powersave (if you really just care about conserving power).

• Libjpeg-Turbo 2.0 Beta Brings More AVX2 SIMD, Improved CMake Build System

  A Phoronix reader recently pointed out that LibJPEG 2.0 Beta quietly shipped last month as working towards the next big update for this speed-focused JPEG library.

  Libjpeg-Turbo 2.0 beta is available for testing and it brings AVX2 SIMD support for colorspace conversion, chroma downsampling/upsampling, integer quantization and sample conversion, and integer DCT/IDCT algorithms. These AVX2 SIMD accelerated paths are generally bringing gains anywhere from 9% to 36% faster depending upon the operation. This version is also bringing SIMD acceleration for Huffman encoding on SSE2 CPUs and Loongson MMI SIMD implementations for more functions.

Vim is an improved version of Vi, a known text editor available by default in UNIX distributions. Another alternative for modal editors is Emacs but they’re so different that I kind of feel they serve different purposes. Both are great, regardless.

I don’t feel vim is necessarily a geeky kind of taste or not. Vim introduced modal editing to me and that has changed my life, really. If you have ever tried vim, you may have noticed you have to press “I” or “A” (lower case) to start writing (note: I’m aware there are more ways to start editing but the purpose is not to cover Vim’s functionalities.). The fun part starts once you realize you can associate Insert and Append commands to something. And then editing text is like thinking of what you want the computer to show on the computer instead of struggling where you at before writing. The same goes for other commands which are easily converted to mnemonics and this is what helped getting comfortable with Vim. Note that Emacs does not have this kind of keybindings but they do have a Vim-like mode - Evil (Extensive Vi Layer). More often than not, I just need to think of what I want to accomplish and type the first letters. Like Replace, Visual, Delete, and so on. It is a modal editor after all, meaning it has modes for everything. This is also what increases my productivity when writing files. I just think of my intentions and Vim does the things for me.

• Mesa 18.1-RC1 Released With The Latest Open-Source 3D Driver Features

  Seemingly flying under our radar is that Mesa 18.1 has already been branched and the first release candidate issued.

  While the Mesa website hasn't yet been updated for the 18.1 details, Dylan Baker appears to be the release manager for the 18.1 series -- the second quarter of 2018 release stream.

At the end of my previous post we concluded with yet another question. Indeed, on the 2017 KDEPIM contributor network we found out that Christian Mollekopf while being a very consistent committer didn't appear as centrality as we would expect. Yet from the topology he seemed to act as a bridge between the core contributors and contributors with a very low centrality. This time we'll try to look into this and figure out what might be going on.

My first attempt at this was to try to look into the contributor network on a different time period and see how it goes. If we take two snapshots of the network for the two semesters of 2017, how would it look? Well, easy to do with my current scripts so let's see!
