To onboard Claude into your codebase, use CLAUDE.md to define your project's WHY, WHAT, and HOW, keeping instructions to a minimum and using Progressive Disclosure to avoid bloating the context window. Avoid auto-generating CLAUDE.md and use linters, code formatters, and other features to handle implementation and formatting separately for better results.
Windows allows drive letters outside of A-Z, but they don't appear in File Explorer and can't be navigated to due to explorer.exe's special logic. The kernel32.dll API SetVolumeMountPointW has a quirk where it truncates non-ASCII drive letters, creating a symbolic link to a different drive letter.

Rodrigo Arias Mallo wants to migrate Dillo project from GitHub to a self-hosted server with multiple mirrors to avoid single point of failure and solve usability issues. He chose cgit as the git frontend and created a simple bug tracker software called buggy to store data in plain text.
Researchers proposed "Program of Thoughts" (PoT) to improve step-by-step reasoning in language models. PoT achieved an average 12% performance gain over state-of-art method Chain-of-thoughts prompting (CoT) on various math and financial datasets.
The European Space Agency's Copernicus Sentinel-1D satellite captured high-resolution images of Antarctica, South America, and Bremen, Germany, within 50 hours of launch. The images show glaciers, ships, and sea pollution, providing valuable data for climate change research and monitoring.
CachyOS is a Linux distribution built on Arch Linux with optimized performance using the BORE Scheduler and advanced instruction sets. It offers various desktop environments and installers, including GUI and CLI options, for a customized experience.
The writer feels AI is being forced on people for profit rather than utility, and wants a more organic adoption process. They want to use AI that works, not a digital god, and value its benefits over tech giants' investments.
The user migrated their GitHub repositories to Codeberg, a process that took a weekend and involved setting up their profile, importing repositories, and configuring CI/CD pipelines. They also successfully migrated their website to git-pages, a service that supports uploading and hosting static websites.
Anomalies in Starlink user data in Yemen and Myanmar were initially attributed to various factors, but civil unrest and ad-blocking measures were found to be contributing factors.

Modern cars collect data on driving habits and personal information through onboard cameras, sensors, and connected services. To minimize data collection, drivers can check their car's data privacy practices, revoke consent, and adjust settings to limit data sharing.
How do you find the root cause of a configuration management failure when you have a peak of hundreds of changes in 15 minutes on thousands of servers? That was the challenge we faced as we built the infrastructure to reduce release delays due to failures of Salt, a configuration management tool. (We eventually reduced such failures on the edge by over 5%, as we’ll explain below.) We’ll ...

Applicant faced uncertainty and self-doubt during graduate school applications due to low GPA and GMAT score. A supportive person's words helped applicant persevere and eventually secure admission.
The user discovered Bidirectional Type Checking, a conceptually simple type checking setup that demystified the whole thing for them, and created a fully functional type checker for a small language. The type checker uses an abstract syntax tree and interweaves inference and checking calls to make type checking straightforward and easy to extend with more features.
The Haribo 20,000 mAh power bank and its earbuds had poor manufacturing controls, increasing the risk of battery failure and fires. CT scans revealed defects such as misaligned layers, torn electrodes, and insufficient anode overhang, compromising safety and reliability.
