  • Git per-branch permissions

    We’ve had Git hosting support in Launchpad for a few years now. One thing that some users asked for, particularly larger users such as the Ubuntu kernel team, was the ability to set up per-branch push permissions for their repositories. Today we rolled out the last piece of this work.

    Launchpad’s default behaviour is that repository owners may push anything to their own repositories, including creating new branches, force-pushing (rewriting history), and deleting branches, while nobody else may push anything. Repository owners can now also choose to protect branches or tags, either individually or using wildcard rules. If a branch is protected, then by default repository owners can only create or push it but cannot force-push or delete; if a tag is protected, then by default repository owners can create it but cannot move or delete it.

  • Open Source Contributor Experience

    We will be covering what contributor experience is, how we help the project, the projects we are current working on (if the talk were today: mentoring, automated workflows, new contributor onboarding, communication pipelines, etc.), and how folks can get involved

  • End of the line for Java 8 public updates – Commercial users at a crossroads

    2018 was a year of uncertainties and misunderstandings for the Java world as people struggled to understand the differences between Oracle JDK vs Oracle’s OpenJDK builds vs OpenJDK builds, the costs involved, whether it’s a good thing to jump on the Java release train or not and the list goes on.

    Some Java Champions joined forces to untangle the Java releases and support confusion; they created a Google Doc which summarizes all the changes Oracle is making, as well as the options Java SE users can choose from. Although the most common provider of Java SE implementations is Oracle JDK, there are others out there such as Azul, Eclipse, IBM, Red Hat, Oracle, SAP, and the list goes on. In short, you can still get the Oracle JDK, Oracle’s OpenJDK builds and OpenJDK by other providers for free.

  • 10 Most Popular Programming Languages In 2019: Learn To Code

    For beginners in the world of programming, the biggest dilemma is to decide where to begin or which language one should master for career benefits. At times, professional coders also face a situation where learning a new language seems more fruitful.

    Whatever may be the reason, here is a list of the most popular programming languages across the world to know which languages are ruling the charts. This list of top programming languages is based on the data sourced from TIOBE Programming Community Index, which is a popular indicator of the popularity of programming languages.

  • What is Raspberry Pi 4 “Model B”? [Ed: I'm still waiting for them to formally apologise for going behind customers' backs, making secret deals with Microsoft to put Microsoft malware on all those devices]

    Raspberry Pi has conquered the world of SoC (System on a Chip). It has already garnered millions of followers since its release in 2012. Not only is it inexpensive, but it’s also versatile, modular, and multi-purpose. It has become popular not only as a credit-sized computer board but also as a controller in electronic, robotics, and IoT projects. The size, features, and price drive the popularity of the Pi, especially in the DIY community. To keep up with the current technological trends, the tiny board has undergone plenty of upgrades over the years, and there have been many varieties so it can cater to the needs and demands of its users. In 2019, the Raspberry Pi Foundation released the fourth generation of the multi-purpose board, the Raspberry Pi 4 B. It is the most powerful Pi to date, sporting huge upgrades from its predecessors. The compact board is touted to deliver a PC-level performance, and it didn’t disappoint.

  • Kentaro Hayashi: Grow your ideas for Debian Project

    There may be some "If it could be ..." ideas for Debian Project. If idea is concreate and worth to make things forward, it should make a proposal for Project Funding. [...] I'm not confident whether mechanism works, but Debian needs change.

  • Sam Thursfield: Calliope, slowly building steam

    There are some interesting complexities to this, and in 12 hours of hacking I didn’t solve them all. Firstly, Bandcamp artist and album names are not normalized. Some artist names have spurious “The”, some album names have “(EP)” or “(single)” appended, so they don’t match your tags. These details are of interest only to librarians, but how can software tell the difference? The simplest approach is use Musicbrainz, specifically cpe musicbrainz resolve-ids. By comparing ids where possible we get mostly good results. There are many albums not on Musicbrainz, though, which for now turn up as false positives. Resolving Musicbrainz IDs is a tricky process, too — how do we distinguish Multi-Love (album) from Multi-Love (single) if we only have an album name? If you want to try it out, great! It’s still aimed at hackers — you’ll have to install from source with Meson and probably fix some bugs along the way. Please share the fixes!

  • Neovide Is A Graphical Neovim Client Written In Rust

    Neovide is a really cool GUI client for Neovim. Although it essentially functions like Neovim in the terminal, Neovide does add some nice graphical improvements such as cursor animations and smooth scrolling. It even has me thinking about making it my new "vim" alias.

Linux 5.11.13, 5.10.29, 5.4.111, 4.19.186, 4.14.230, 4.9.266, and 4.4.266

Get involved with Mageia, become a Packager

With Mageia 8 just released and development for Mageia 9 getting underway in Cauldron, the unstable branch of Mageia, now is a great time to get involved with packaging. We are starting to look at the features that we want to include for Mageia 9, and as it is so early in the development cycle, now is the time for major developments, or big updates to key pieces of software. This is a great time to join the project as you can propose features you would like to see, help to implement large changes or see how a distribution evolves through development, stabilisation and then is released. If there is an application that you are interested in, if you want to help maintain part of the distribution, or if you want to learn something new, there are many opportunities to do so with the packaging team.

Google does not want you to tell your players about your donation page

I recently updated Pixel Wheels banner image on Google Play. That triggered a review of the game: shortly after the update I received a message telling me Pixel Wheels was "not compliant with Google Play Policies". What nefarious activity does the game engage in? Sneak on users? Mine bitcoins? [...] Meanwhile you can still get the game from F-Droid or itch.io, since they do not have a problem with a link to a donation page. Read more
