Linux's contemporary filesystem mount API lacked documentation for six years until the latest man-page package finally added content for the 2019 code. The new API introduced calls like "fsconfig," "fsmount," and "fsopen," replacing the old "mount" and offering developers cleaner code and better error handling. Despite drafts of man-pages being written in 2020, they were not merged due to potential incompleteness. Documentation master Christian Brauner created a repository with Markdown versions of the pages in 2024, making the necessary information more accessible. The delay in documentation may have contributed to filesystem handlers like Ext4, CIFS, Btrfs, and F2FS implementing the new API at different times.

Aviation enthusiast uses Raspberry Pi and ADS-B radio to create viral real-time airport tracker — open-source 'Skylight' intercepts aircraft signals and projects flight paths onto your ceiling

Software engineer Cameron Paczek created Skylight, an open-source project using a Raspberry Pi 5 and ADS-B radio to track aircraft in real-time and project their flight paths onto your ceiling. Skylight captures ADS-B signals emitted by planes, decodes them, and displays details like model, altitude, and distance to destination on your ceiling. The project also recreates the sky with celestial bodies and live satellite tracking. Paczek plans to release a ready-made kit for Skylight to make it more accessible to those who are not tech-savvy.

Github Copilot customers report up to 100-fold price hikes — AI sticker shock bites as Microsoft switches to usage-based pricing

GitHub Copilot has transitioned to usage-based pricing, leading to significant price hikes for customers. Users are reporting bills increasing by up to 100-fold, with some finding subscription plans limited or useless due to low usage limits. The new pricing model includes token allowances in different subscription tiers, but estimating token usage for queries can be challenging. Users are advised to carefully select efficient models to manage costs, as some have experienced unexpectedly high token consumption even with light usage. Investors are pushing for AI companies to generate more revenue to match their expenditures, despite backlash against Microsoft for the pricing changes.

Linux prepares to axe legacy x32 hybrid mode — hybrid 32-bit/64-bit mode faces complete removal by 2027 due to low adoption

The Linux kernel is considering removing the x32 ABI, a hybrid 32-bit/64-bit mode introduced in 2012, by 2027 due to low adoption rates. The x32 ABI aimed to optimize memory consumption for 64-bit programs by using 32-bit pointers while accessing the full 64-bit register file. Despite its potential performance improvements, the x32 ABI faced challenges such as complexity for developers and limited memory usage per process. The lack of mainstream adoption and exclusivity to Linux contributed to its demise, as it did not see widespread use by software developers.
