Ethical Code Hosting Services in 2020

Filed under

I was really inspired by Free Software Foundation's list of ethical repositories in which I saw service there among other old longstanding services. The Foundation (often called FSF) is a serious organization with long consideration if they wish to update that list. However, in fact, there are many more services coming by time and now there are several interesting ones worth to try and enjoy. Although I myself am not a programmer, but code hosting is not unfamiliar to me, as a free software community member (just like you all, dear readers) I often get so many useful information and sometimes submit bug report to projects I love. You can, for example, take information here as reference to host a Git server software at your home as you see perhaps many serious projects also using it. As an author and mere free software user, I hope this list could be useful for everybody and particularly for programmers. Happy hacking!

OSS: Events, Google Summer of Code and More

  • What are the pros and cons of virtual events?

    The COVID-19 pandemic disturbed the work of event organizers everywhere. To slow the spread of this highly contagious virus, conferences that tend to host thousands in person faced a choice: Move entirely online, or cancel altogether. Many open source event organizers chose the latter, but not all of them. Open Source 101 was due to be held in Austin, TX, on April 14. Instead, it hosted 1,000 attendees virtually. Later this month, the Linux Foundation will host the annual North American contingent of its Open Source Summit online. And rather than hosting DrupalCon around the world as planned, the Drupal Association will host DrupalCon Global online from July 14 - 17. [...] On a personal note, I've shared before how I started contributing to open source after attending a huge conference where I met several community leaders. By meeting and making connections face to face, I got plugged in much faster than if I had stumbled onto GitHub and searched through random projects. I fully support public health efforts to keep people safe, and haven't found virtual events to be a strong substitute for the informal conversations in the "hallway track."

  • Should I stay or should I go to Akademy?

    I have submitted two talks proposals to Akademy. Earlier Albert called for more proposals, so let me repeat his reminder: send your talks proposals early to reduce panic in the programme committee. Anyone can join! And all things KDE and Qt related are good, as well as interesting stuff on the edge of the KDE community. [...] So be part, and send in your tale of KDE community activity.

  • Google Summer of Code 2020 - Week 1

    This week, I started working on the Rocs graph layout capabilities. The Fruchtermani-Reingold [1] algorithm seems to be the most common option for drawing graphs automatically when no extra information about the graph is known. In fact, the Boost library implementation of this algorithm is currently being used by Rocs. However, the Fruchtermani-Reingold algorithm has some parameters that can change its results deeply. In order to better understand the algorithm and how different parameterizations lead to different results, I wrote my own C++ implementation directly in the Rocs’ libgraphtheory. This allowed me to generate debug information during the execution of the algorithm. Unfortunately, tuning the parameters directly into the implementation is time consuming. Automatic parameter tuning solutions can not be applied in a trivial way, because the quality of the result obtained for a given parameterization is quite subjective. Therefore, I decided to make my manual tuning and evaluation process more efficient by creating a user interface that will allow me to choose parameter values and apply the algorithm to the current graph. Because I am new to Qt and the way to do this is to implement a Rocs’ plugin, it is not done yet. Creating such interface was already in my plans, but I expected to do it later.

  • [LibreOffice] How your donations helped us in 2019
  • Equity and the Power of Community

    Over the past week, I’ve been thinking a lot about George Floyd, Breonna Taylor, and Ahmaud Arbery. I have been thinking about white supremacy, the injustice that Black women and men are standing up against across the world, and all the injustices I can’t know, and don’t see. The WordPress mission is to democratize publishing, and to me, that has always meant more than the freedom to express yourself. Democratizing publishing means giving voices to the voiceless and amplifying those speaking out against injustice. It means learning things that we otherwise wouldn’t. To me, it means that every voice has the ability to be heard, regardless of race, wealth, power, and opportunity. WordPress is a portal to commerce; it is a canvas for identity, and a catalyst for change. [...] If you would like to learn more about how to make a difference in your own community, here are a few resources I’ve gathered from WordPressers just like you.

Servers: Kubernetes, Compression and Debian Activities

  • The state of Kubernetes: 6 facts you might not know

    Kubernetes celebrates its sixth birthday on June 7: One of the fastest-growing open source projects ever, it’s driving significant change in enterprise IT, helping developers manage containers at scale. Moreover, it helps them develop applications faster and manage resources in automated ways. That’s important not only in DevOps and agile environments, but also in any enterprise IT environment pushing for faster software development and more experimentation. And any CIO or IT leader will tell you, the CEO’s biggest wish right now is faster response to customer needs and outside changes - most recently, a global pandemic. How much Kubernetes growth are we talking about? According to the CNCF Cloud Native Survey for 2019, 78 percent of respondents were using Kubernetes in production, up from 58 percent the previous year.

  • Russell Coker: Comparing Compression

    For distributions like Debian which have large archives of files that are compressed once and transferred a lot the “zstd --ultra -22” compression might be useful with multi-threaded compression. But given that Debian already has xz in use it might not be worth changing until faster CPUs with lots of cores become more commonly available. One could argue that for Debian it doesn’t make sense to change from xz as hard drives seem to be getting larger capacity (and also smaller physical size) faster than the Debian archive is growing. One possible reason for adopting zstd in a distribution like Debian is that there are more tuning options for things like memory use. It would be possible to have packages for an architecture like ARM that tends to have less RAM compressed in a way that decreases memory use on decompression. For general compression such as compressing log files and making backups it seems that zstd is the clear winner. Even bzip2 is far too slow and in my tests zstd clearly beats gzip for every combination of compression and time taken. There may be some corner cases where gzip can compete on compression time due to CPU features, optimisation for CPUs, etc but I expect that in almost all cases zstd will win for compression size and time. As an aside I once noticed the 32bit of gzip compressing faster than the 64bit version on an Opteron system, the 32bit version had assembly optimisation and the 64bit version didn’t at that time.

    This month I accepted 211 packages and rejected only 9. The overall number of packages that got accepted was 228.
