• Experimental Support For C++20 Coroutines Has Landed In GCC 10

  As of this morning experimental support for C++20 coroutines has been merged into the GCC 10 compiler! Coroutines allow a function to have its execution stopped/suspended and then to be resumed later. Coroutines is one of the big features of C++20. Sample syntax and more details on C++ coroutines can be found at cppreference.com. Coroutines support for GCC has been under development for months and now as a late addition to GCC 10 is the experimental implementation.

• GNU Binutils 2.34 Branched - Bringing With It "debuginfod" HTTP Server Support

  With GNU Binutils 2.34 comes debuginfod support, which is the HTTP server catching our eye while the debuginfod server is distributed as part of the latest elfutils package. This isn't for a general purpose web server thankfully but is an HTTP server for distributing ELF/DWARF debugging information and source code. With debuginfod enabled, Binutils' readelf and objdump utilities can query the HTTP server(s) for debug files that cannot otherwise be found. Enabling this option requires building Binutils using --with-debuginfod.

• Announcing git-cinnabar 0.5.3

  Git-cinnabar is a git remote helper to interact with mercurial repositories. It allows to clone, pull and push from/to mercurial remote repositories, using git.

• Steve Kemp: Announce: github2mr

  myrepos is an excellent tool for applying git operations to multiple repositories, and I use it extensively. I've written several scripts to dump remote repository-lists into a suitable configuration format, and hopefully I've done that for the last time.

• Term::ANSIColor 5.01

  This is the module included in Perl core that provides support for ANSI color escape sequences. This release adds support for the NO_COLOR environment variable (thanks, Andrea Telatin) and fixes an error in the example of uncolor() in the documentation (thanks, Joe Smith). It also documents that color aliases are expanded during alias definition, so while you can define an alias in terms of another alias, they don't remain linked during future changes.

• Python 3.7.5 : Django security issues - part 001.

  Django like any website development and framework implementation requires security settings and configurations. Today I will present some aspects of this topic and then I will come back with other information.

• How to display flash messages in Django templates

  Sometimes we need to show the one-time notification, also known as the flash messages in our Django application. For this Django provides the messages framework. We are going to use the same here. To show flash messages in the Django application, we will extend our previous project Hello World in Django 2.2. Clone the git repository, check out the master branch and set up the project on your local machine by following the instructions in the README file.

KDE: Videos, Plasma and Itinerary

• So you want to make a KDE video...

  KDE is running a competition in search of the next great promotional video for KDE's Plasma desktop and KDE's applications. The prizes are two fantastic TUXEDO computers, one per category, which will undoubtedly boost your film rendering capacity. There are also 12 goodie packages for runner-ups, and who doesn't need more Linux shirts, caps and stickers? Although we have already received some interesting entries, we feel it may be time to help video artists out there with ideas from the judges themselves. Below, Julian Schraner, Ivana Isadora Devčić, and Paul Brown from the Promo team and Farid Abdelnour from the Kdenlive team give their views on what a KDE promotional video should look like, where to find resources, and which pitfalls may hurt your film if you fall for them.

• Learning about our users

  In a product like Plasma, knowing the kind of things our existing users care about and use sheds light on what needs polishing or improving. At the moment, the input we have is either the one from the loudest most involved people or outright bug reports, which lead to a confirmation bias. What do our users like about Plasma? On which hardware do people use Plasma? Are we testing Plasma on the same kind of hardware Plasma is being used for? Some time ago, Volker Krause started up the KUserFeedback framework with two main features. First, allowing to send information about application’s usage depending on certain users’ preferences and include mechanisms to ask users for feedback explicitly. This has been deployed into several products already, like GammaRay and Qt Creator, but we never adopted it in KDE software. The first step has been to allow our users to tune how much information Plasma products should be telling KDE about the systems they run on.
