GNU FreeDink - One Of The Few Fully Free Software Games - Now Runs On The Web

When it comes to obscure projects under the official GNU Project umbrella, GNU FreeDink is one of them as being a free software game whose lineage traces back to the Dink Smallwood title from the late 90's. Nearly twenty years after the game's original release, the latest GNU FreeDink release is now available that allows it to be played within web-browsers.

Some Compiler Performance Benchmarks With The Zapcc Caching Compiler

Here are some quick benchmarks I ran this week of the newly open-sourced Zapcc C++ caching compiler based upon LLVM/Clang and compared to the upstream Clang performance, GCC, and Ccache with the speed on the original compilation of the benchmark code and then again on a subsequent compilation.

Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS

Following the news yesterday of OpenBSD disabling Intel Hyper Threading by default within its OS over security concerns and plans to disable Simultaneous Multi Threading for other processors/architectures too, here are some fresh Intel HT benchmarks albeit on Ubuntu Linux. The OpenBSD developer involved characterized HT/SMT as "doesn't necessarily have a positive effect on performance; it highly depends on the workload. In all likelihood it will actually slow down most workloads if you have a CPU with more than two cores." So here are some benchmarks using a current-generation Intel Core i7 8700K six-core processor with Hyper Threading.

Purism's Librem 5 To Rely On Secondary Processor For Binary Blobs

With not being able to deliver a 100% fully free software / libre system, the Librem 5 smartphone will rely upon a secondary processor for dealing with the necessary binary blobs for hardware initialization to keep them out of touch from the U-Boot boot-loader and Linux kernel.

Using W10Privacy To Boost Ubuntu WSL Performance On Windows 10

While Microsoft is working on low-level improvement to the Windows Subsystem for Linux (WSL) to yield better I/O performance, it is possible to dramatically increase some disk workloads by removing a number of running Windows services via the independent W10Privacy application. Here are some benchmarks of W10Privacy on the overall performance impact to Microsoft Windows 10 Pro x64 itself and of Ubuntu 18.04 running on the Windows 10 installation via WSL.

OpenGL Floating Point Textures No Longer Encumbered By Patents, Enabled In Mesa

Back in 2012 when talking with Gabe Newell of Valve about open-source/Linux challenges one of the topics he was awed about was patents encumbering the open-source graphics driver progress. Six years later, Timothy Arceri working on the Valve Linux graphics driver team has freed Mesa's ARB_texture_float support from being built conditionally due to these patent fears.
