AtomixDB is a Go-based relational database featuring B+ Tree storage, transaction support, and concurrent read capabilities. The project implements core database functionality including storage management and transaction handling, making it suitable for learning database internals and read-heavy applications.
PostgreSQL's unique position as a truly open-source, advanced relational database with extensive modularity is driving its accelerating adoption across the industry. EdgeDB announces its rebranding as Gel, introducing full SQL support and deeper ecosystem integration while maintaining its role as a PostgreSQL frontend layer enhancement. The platform aims to provide seamless database integration similar to how TypeScript enhances JavaScript.
Penn State engineering student Divya Tyagi refined a century-old mathematical problem in wind turbine design, creating a simpler solution to Glauert's original work. Her addendum expands the analysis to include total force and moment coefficients acting on wind turbine rotors, enabling more efficient turbine designs. The breakthrough could significantly improve wind energy production, with even a 1% efficiency increase potentially powering an entire neighborhood.
An analysis debunking claims about extremely high IQ scores (160+) reveals that such measurements become increasingly unreliable and meaningless at higher ranges. Historical genius figures like Einstein likely had more modest IQs around 120-130, with test scores being highly variable and practice-dependent. The correlation between IQ and real-world outcomes diminishes significantly beyond certain thresholds.
A developer shares their experience building a minimalist compiler called TinyCompiler for a custom programming language 'wend' over a weekend. The project aims to translate 'wend' code into GNU assembly while maintaining a codebase of around 500 lines of Python, serving as an educational exploration of compiler theory.
Bluesky implemented a 'Lossy Timelines' system to improve performance by intentionally dropping some timeline updates for users who follow many accounts. This solution reduced fanout latency by 96% and eliminated hot shard issues in their database clusters. The approach demonstrates how embracing imperfection in system design can lead to better scalability and performance.
WEST tokamak in France achieved a record-breaking 1,337-second plasma duration at 50 million degrees, surpassing China's EAST facility by 25%. This milestone advances fusion research towards ITER's goal of maintaining plasma for several minutes, with researchers now aiming for longer durations and higher temperatures.
An in-depth analysis reveals that word embedding models like word2vec aren't inherently superior to traditional distributional semantic methods, with hyperparameter optimization being more crucial than algorithm choice. The study demonstrates that Singular Value Decomposition (SVD) often outperforms popular embedding methods in word similarity tasks, while Skip-gram Negative Sampling (SGNS) excels in analogy tasks.
PAROL6 is an open-source, 3D-printed desktop robotic arm designed to match industrial robot standards in mechanics, control, and usability. The project provides comprehensive documentation, building instructions, and control software under GPLv3 license, enabling users to build and operate their own 6-axis robot for educational and small-scale automation purposes.
Jane Street introduces Figgie, a fast-paced trading simulation game that teaches market dynamics while providing entertainment value.
