Yek: A Fast Tool for Chunking Repository Files for LLMs

Yek is a fast Rust-based tool designed to read text-based files from a repository or directory, chunk them, and serialize them for Large Language Model (LLM) consumption. It intelligently skips unwanted files (using .gitignore rules and Git history), splits content into chunks based on token count or byte size, and offers extensive configuration options such as custom ignore patterns and file priority rules. Yek aims to streamline the data preparation process for LLMs, boosting efficiency.

HP Scraps 15-Minute Phone Support Wait Time After Backlash

HP abruptly reversed its controversial policy of imposing a 15-minute mandatory wait time for telephone support. The policy, implemented in several European countries, aimed to push customers towards online support channels. However, negative feedback from both customers and internal staff led to its swift cancellation. HP stated that timely access to live agents is paramount and they will prioritize quick phone support.

Visualizing Ruby's Lazy Enumerator: A Simple Trick

This article uses an interactive demo to explain Ruby's lazy enumerator, `Enumerator::Lazy`. Unlike default eager enumeration, lazy enumeration only computes elements when needed, avoiding unnecessary work, especially beneficial with large datasets or complex data transformation pipelines. The article visually demonstrates the difference using 'vertical' and 'horizontal' analogies and suggests resources for a deeper dive into Ruby's lazy implementation.

Beyond Cron: Building Robust Scheduled Backups with systemd

Tired of Cron's limitations? This article shows how to build a more reliable, monitorable, and manageable scheduled backup system using systemd. By creating systemd timer and service files, you can easily schedule the execution of backup scripts and add pre- and post-execution actions, such as sending notifications of backup success or failure, using ExecStartPre and ExecStopPost. systemd's persistence mechanism ensures that backup tasks are reliably executed even after system restarts, while its logging and monitoring capabilities significantly improve system maintainability. Leave Cron's shortcomings behind and embrace the convenience and reliability of systemd!

SAP's Ex-CTO Paid €7.1M After Sexual Harassment Allegations

Former SAP CTO Jürgen Müller received a €7.1 million severance package after leaving the company following allegations of sexual harassment. The incident occurred at a company event, and Müller admitted to inappropriate behavior and apologized. The investigation concluded, resulting in a mutual agreement for his departure. Meanwhile, other executives, Scott Russell and Julia White, received severance payments of €12.6 million and €9 million respectively. Despite these high-profile departures and significant payouts, SAP reported strong 2024 results, with cloud and software revenue reaching €29.96 billion and operating profit exceeding expectations. SAP's share price has also increased by approximately 50 percent in the past year.

Beyond Reproducible Builds: Towards Idempotent Rebuilds of Debian

2025-04-04

This article explores a new goal beyond reproducible builds for Debian packages: idempotent rebuilds. The author argues that simply reproducing published packages using older build dependencies (as done by the Reproduce.Debian.net project) is insufficient, as it relies on old binary packages that cannot be rebuilt from source. Therefore, the author proposes the concept of idempotent rebuilds, where iterative rebuilding eventually leads to a state where the rebuilt packages are identical to the previous iteration. This requires addressing issues like build timestamps and non-deterministic outputs. The author has completed stage 0 of the rebuild and plans to release the build artifacts for stage 1, with the ultimate goal of being able to bootstrap a Debian binary distribution from an environment like Guix. Challenges include the presence of non-free firmware and non-Debian signed binaries which might prevent self-rebuilding.

Sand Mafia: How Gangs Are Making Millions from Illegal Sand Mining in Latin America

Just outside Rio de Janeiro, a powerful gang, led by 'Zinho,' amassed a fortune through illegal sand mining. Using heavy machinery, they extracted vast quantities of sand, fueling a lucrative, unregulated real estate market and monopolizing services for illegally constructed buildings. This activity not only caused significant environmental damage, including flooding and habitat destruction, but also fostered corruption and violence, with links to political figures and even murder. Similar operations in Colombia and Mexico reveal a widespread problem, where illegal sand mining is a highly profitable criminal enterprise with devastating consequences for the environment and social stability.

Hamburger Menus: A Decade Later, Are They Still Usable?

A decade on, the hamburger menu is a ubiquitous navigation pattern. However, the old problems of hidden navigation persist: users overlook it, leading to increased task completion times and decreased satisfaction. While user recognition of the hamburger menu has improved, design risks remain. This article revisits early research findings, shares new research on hamburger menu recognizability, and offers visual design best practices for the hamburger icon. Research shows that the standard three-line icon, top-left placement, and clear labels improve hamburger menu usability. But the article cautions that hidden navigation always adds interaction cost and visible navigation should always be prioritized. Use them wisely, follow best practices, and always test with users.

Can LLMs Accurately Recall the Bible?

Can LLMs Accurately Recall the Bible?

This article investigates the ability of Large Language Models (LLMs) to accurately recall biblical scripture. The author devised six tests evaluating different sized LLMs' ability to accurately reproduce verses. Larger models (Llama 405B, GPT 4o, and Claude Sonnet) performed best, accurately recalling verses and even entire chapters. Smaller models (7B parameter range) frequently mixed translations or hallucinated text. Medium-sized models (70B range) generally preserved the meaning but often blended translations or paraphrased slightly. The author concludes that for accurate biblical quotations, larger models are preferable, supplemented by verifying against an actual Bible.

The Non-Deterministic Nightmare of React UI Testing

2025-01-31

Testing React UIs presents a unique challenge due to its asynchronous update mechanism. Unlike direct DOM manipulation, React's renderer updates the UI asynchronously, making it difficult for tests to precisely capture the timing of UI state updates. Testing utilities like `act` and `waitFor` offer workarounds, but essentially boil down to 'eventually, something will happen'. Minor UI changes (like animation delays, state update order) can easily break tests, requiring extensive modifications to existing test suites. This results in high maintenance costs for React UI testing, a common pain point for many development teams.
