  • 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

  • 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.

  • 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.

How I turned an old Chromebook Pixel into a native Linux laptop running Ubuntu

If you’ve visited the Chrome OS subReddit, you’ve surely seen posts by Mr. Chromebox there. For several years, he’s been the go-to authority for doing major operating system and firmware changes to dozens of Chromebook models so you can natively install Windows or Linux on your device. I haven’t delved into this type of esoteric but useful project in a while but a CompSci classmate is thinking about switching from Windows 10 to Linux. So I dug around the closet where good Chromebooks go to collect dust and found the 2013 Chromebook Pixel I bought new seven years ago. This is a perfect candidate for a Linux installation because the last software update pushed to it was Chrome OS 69. So it’s not the most secure device for browsing at the moment. Read more

Manjaro 19 Kyria Gnome - Fairly well put together

Manjaro 19 Kyria is a solid, rounded distro - at least, the Gnome version is. But I presume results are quite similar across the board. Surprised, I am, as I was expecting something less polished. I do have to say that Kyria has some nice points, it's colorful, stable and rather friendly, and the package management is a tad better than in the past. However, it does suffer from oddities. The application collection is too wild and undefined, some software has been added without any consideration to the espirit-de-distro, smartphone support can be better, and more battery time would be nice, too. Maybe this is Manjaro transforming from a leetbox to the Average Joe consumer thingie, or maybe this is a neverending part of the cosmic randomness called Linux desktop. We shall see. For now, testing, you ought. Grade? 5/7, I'd say. On a serious note, 8/10. I shall be keeping an eye on them other flavors. Take care. Read more
