The GPS system is a marvel of engineering, with GPS signals being ever-present at any altitude, in any weather, at all times. Despite the signals being incredibly weak, they can still be detected and decoded thanks to clever signal processing techniques. GPS uses spread-spectrum and code-division multiple access tricks to help receivers lock onto the […]
The T5 model has been a favorite in the NLP community, but improvements were made with the creation of Pile-T5, a new version trained on the Pile dataset using the LLAMA tokenizer. This new model outperforms the original T5 and even its token-matched settings, especially excelling in code-related tasks. The Pile-T5 models were evaluated on […]

To reach space without giant fuel tanks, the idea is to use a massive airship to slowly accelerate with electric/chemical hybrid rocket engines over days until reaching orbital velocity. The airship would need to be over a mile long and exceptionally light, creating a three-stage approach due to complications like flying at the edge of […]
The author shares their frustration with Firejail and their updated approach to sandboxing applications using Flatpak and BubbleBox. Flatpak is preferred for software with existing sandboxes, but may require global overrides to avoid liberal profiles. BubbleBox is used for software that does not have a Flatpak or needs to run on the host system but […]
WireViz is a handy tool for documenting cables, wiring harnesses, and connector pinouts using plain text and YAML files. It produces visually appealing graphical output thanks to GraphViz and offers features like automatic BOM creation and custom color schemes. It’s ideal for both simple cables and complex harnesses, with options for easy autorouting and wire […]
In a series of posts aimed at C++ practitioners, the author offers a unique and thoughtful approach to learning Swift. By mapping C++ idioms and patterns onto Swift, readers are guided through the similarities and differences between the two languages. Highlighting Swift’s magic elements like type-checked generics and value types, the author also addresses controversial […]
US startup RocketStar has successfully demonstrated an electric propulsion unit for spacecraft that uses nuclear fusion-enhanced pulsed plasma, known as the FireStar Drive. This innovative system ionizes water vapor to generate high-speed protons that collide with the nucleus of a boron atom, creating fusion, improving thrust by 50%. The fusion-fission reaction was first devised during […]
