HackerBooks is a website that collects books mentioned on Hacker News and presents them as a daily reshuffled list of well-loved titles. It lets users rank books by score and shows how many times each has been recommended or mentioned.
PostgreSQL 19 is expected to ship later than usual because several major features were reverted late in the beta cycle. The delay stems from a surge in bug reports, many discovered with the help of LLMs, which has increased the workload for fixing and reviewing code across current and older releases. The project’s focus on quality is causing the postponement, though the long-term impact of uncovering decades of latent bugs remains uncertain.
Wikihack is a Hacker News-inspired site that collects Wikipedia articles referenced in Hacker News discussions and displays their summaries alongside discussion activity. The sample entries cover topics such as bipolar disorder, the Data Encryption Standard, Scotland's Silicon Glen, Experts Exchange, and head-related transfer functions. It aims to make frequently mentioned Wikipedia subjects easier to discover and contextualize.
HackerTube is a YouTube-style site that curates videos based on recommendations found in Hacker News comments. It filters a large dataset of comments to identify video links, then presents them in a clean interface with custom recommendations, keyboard shortcuts, and no user accounts. The project demonstrates how AI coding tools can rapidly build a personalized alternative to mainstream video recommendation algorithms.
The article announces an updated website and API that collects Linux system call tables for 27 architectures, including syscall numbers, arguments, registers, and history from Linux 3.3 through 7.3. Each architecture's data is available as a plain JSON file, and the site also documents the calling conventions used to pass arguments and return values. It serves as a centralized reference for developers working with Linux system calls across different CPU architectures.
After the first Berkeley Software Distribution, improvements and new tools such as vi and the C shell were packaged into 2BSD and distributed on tape. The arrival of a VAX at Berkeley highlighted the need for virtual memory, especially for symbolic computation work, and helped shape BSD Unix’s development. Meanwhile, ARPANET and DARPA interest in portable Unix made Berkeley’s distributions influential across research institutions.
The article suggests that bones can secrete proteins that influence aging processes. These proteins may help slow age-related decline and potentially extend lifespan.
This Hacker News post asks for TV recommendations that prioritize user privacy, likely focusing on models with minimal data collection, limited smart features, or local-only operation. It is probably a discussion about which brands or settings reduce tracking, cloud dependencies, and smart TV surveillance.
Researchers have solved the mystery behind recurring 60-second fluctuations in power grids. The finding clarifies a previously unexplained pattern in grid behavior and may help improve the stability and reliability of electrical networks.
HackerHack recreates the Hacker News homepage as a browsable feed of posts posted on HN itself, a companion to sister aggregators like HackerTube (videos) and HackerBooks (books). The author notes no AI was used to build it, and commenters praise the faithful, "no AI slop" user experience.
