  • GammaRay 2.11.1 Release

    We have released version 2.11.1 of our Qt application introspection tool GammaRay. The changes mainly focus on establishing full compatibility with Qt 5.14 as well as bugfixes and performance improvements, but there’s also a few new features.

    Areas most affected by changes in Qt 5.14 are the inspection of Qt Quick software rendering, deployment on Android and signal monitoring. We also fixed a major performance issue that can be caused by interference between the newly added event monitor in GammaRay 2.11 and the Qt Quick remote view feature, as well as the in-app widget overlay causing layouting issues when applied to a QSplitter. The Qt 3D geometry inspector now has a OpenGL ES2 fallback implementation in case your host machine doesn’t support OpenGL 3, and the event monitor can now also visualize event propagation in Qt Quick’s input handling.

  • When do you code?

    Recently, we published an article about why developers prefer to code at night. Author Matt Shealy highlighted the many benefits of nocturnal programming including the quiet time and space for creative thinking.

    An optimal time of day to code is far from an absolute science. There is evidence to support we all work from a circadian rhythm, but that does not mean we all work on the same clock when it comes to productivity.

  • To-Study Plan: a beginning to OO in Perl

    Now I have a todo list command-line script. I want to have a to-do list for my wikipedia editing activities, a to-study list for math I want to study sparely, a to-study-or-to-code in computer programming and maybe a to-read list for books.

System76 Thelio Major Proves To Be A Major Player For Linux Workstations

For the past two months we have been testing the System76 Thelio Major and it's been working out extremely well with performance and reliability. The Thelio Major offering with options for Intel Core X-Series or AMD Ryzen Threadripper and resides between their standard Thelio desktop with Ryzen/Core CPUs and the Thelio Massive that sports dual Intel Xeon CPUs. The Thelio Major is the platform we have been using for all of our AMD Ryzen Threadripper 3990X testing and it's been working out great. The Thelio Major besides having Threadripper and Core X-Series CPU options can be configured with up to 256GB of RAM, up to two GPUs, and up to 46TB of storage for really yielding incredibly powerful Linux workstation performance potential.

Deprecating support for the Linux kernel

Running on the Hurd was always a goal for Guix, and supporting multiple kernels is a huge maintenance burden. As such it is expected that the upcoming Guix 1.1 release will be the last version featuring the Linux-Libre kernel. Future versions of Guix System will run exclusively on the Hurd, and we expect to remove Linux-Libre entirely by Guix 2.0. The Linux kernel will still be supported when using Guix on "foreign" distributions, but it will be on a best-effort basis. We hope that other distributions will follow suit and adopt the Hurd in order to increase security and freedom for their users. Read more Also: Guix deprecating support for the Linux kernel

Plasma Mobile: How to help us!

We often get asked: “how long until the 1.0 release?”. Or: “how far away is Plasma Mobile 1.0?”. The usual answer to both these question is “It’ll be ready when it is ready”. But, really, how do we know that it is ready? Recently some of us prepared a check list of items which we consider necessary before we can declare Plasma Mobile “ready” or at rc1 status. Read more
