GabeN Is Shitting Yacht Money into Flatpak and You're Still Arguing Init Systems

The Linux community has lost sight of its ideals and is now driven by ideology, causing unnecessary fragmentation and making it difficult for users to access and use Linux-based applications. This fragmentation is driven by a wealth transfer from developers to ideologues, and it's harming the community's reputation and driving users away, with corporations like Valve and Canonical doing great ...

Electrical transformer manufacturing is throttling the electrified future

A major fire at a Heathrow Airport substation caused a power outage, highlighting the fragility of the world's infrastructure due to a shortage of transformers. The shortage is caused by a combination of factors including a lead time of over a year for new transformers, a lack of skilled engineers, and a reliance on special materials that are difficult to produce.

Breaking Enigma with Index of Coincidence on a Commodore 64

https://imapenguin.com/images/2026/04/enigma-ic-found.webp
The Index of Coincidence (IC) attack is a method to crack Enigma codes without a crib, using the statistical properties of the German language to identify the correct rotor settings. The IC attack requires decrypting the entire message for every candidate setting, which is slower than a crib-based attack but can be done on a Commodore 64 in 82 hours, producing 18,165 candidates.

Embarrassingly simple self-distillation improves code generation

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
A large language model can improve at code generation using its own raw outputs through simple self-distillation, which fine-tunes the model on its own samples. This method improves model performance on harder problems and generalizes across different model scales and variants.
