The author discusses the formalisation of mathematics and the rise of Lean, but notes that it's not the first system to achieve this. They mention AUTOMATH, which was developed in the 1960s and 1970s, and other systems like HOL Light and Isabelle/HOL. The author argues that Lean's success is partly due to its user community and the abandonment of "constructive proofs".
pgBackRest is a reliable PostgreSQL backup and restore solution that scales up to large databases and workloads. It supports parallel processing, compression, and block-level backups for efficient data storage and retrieval.
Dirac is an open-source coding agent that improves accuracy and reduces costs by 64.8% with tightly curated context. It achieves 100% accuracy on complex refactoring tasks at a fraction of the cost of other leading agents.
A data breach at Mercor exposed 40,000 contractors' voice biometrics and ID documents. Attackers can use this data to clone voices and commit crimes like bank verification bypass and vishing.
The DSPi transforms a Raspberry Pi Pico into a digital audio processor with features like room correction, active crossovers, and parametric EQ. It acts as a USB sound card with onboard DSP engine.
The user tested a MacBook's local LLM capabilities on a 10-hour flight, processing 4M tokens and discovering local inference's viability for tight-scope coding and exploratory tasks.
User tried Simple Lucas' focus routine, staring at a wall to recover focus, and found it effective but hard. They attribute their lack of focus to information overload and use wall staring with parasympathetic activation and mind blanking to improve productivity.
Tendril is a self-extending agentic sandbox that discovers and builds tools autonomously. It uses a Strands agent with three bootstrap tools to rule them all.

The user built a large interactive wall art using flipdiscs, a display type that utilizes electromagnetic pulses to flip small discs between two colors, and paired it with an Nvidia Orin Nano for processing power. The user created a library for using flipdisc screens in Node.js and built a reliable interface for the display using an expo app, allowing users to control and customize the display.
Scratch has a long history of SVG-related vulnerabilities. The source of these is that Scratch parses user-generated (ie. attacker-controlled) content into an <svg> element and appends it into the main document for various operations (eg. measuring SVG bounding box in a more reliable way than viewbox or width/height). No matter how briefly the SVG remains in the main document, this is ...

The domain name friendster.com was bought for $7456 in an auction and later sold for $20k in Bitcoin. The new owner created a social network with unique features like phone tapping to connect friends and fading connections to encourage in-person interactions.
Researchers at the Max Planck Institute found that lithium-metal electrodes generate hydrostatic stress causing the solid electrolyte to fracture during charging. This discovery could help prevent short circuits in solid-state batteries and pave the way for their commercial use.

No boilerplate Versatile Whether you are writing a research paper, a quick report, a company-wide wiki, class notes, or preparing interactive slides for your next talk, there's only one line you need.
The future of software engineering will belong to those who use AI to augment their skills, not replace them, by focusing on judgment, clarity, and original thought. Effective engineers will know what to delegate to AI and what to own, turning time savings into better thinking and avoiding the trap of shallow understanding and imitation.
The library opens various file formats including CSV, TSV, and native .cell files. It tracks ODF formula compliance and saves CSV files with flattened formula values.
The user built a custom "front page" printer using a dot matrix printer, Raspberry Pi, and PHP script to print out news, stocks, and Reddit posts every morning. The project was a fun way to integrate old hardware with new technology and reduce screen time, and the user plans to explore more uses for the dot matrix printer.
A vector is an ordered list of numbers that can be thought of as an arrow in space, and its length and inner product can be calculated using the norm and dot product. The goal of TurboQuant is to store a vector using a fixed number of bits per coordinate while minimizing the mean squared error (MSE) of the reconstructed vector, and it achieves this by applying a random rotation to the vector ...
The user built an automated screenshot system for a help centre in Jelly, using Rake tasks and a headless Chrome browser. This system updates screenshots automatically when the UI changes, reducing maintenance and keeping the help centre current.
The TL-SG108 is an 8 port Gigabit Ethernet switch based on the Realtek RTL8370N chip, which can be upgraded to a managed switch by replacing the 4Mbit SPI flash with a 32Mbit one. The switch's MAC address and serial number can be modified to avoid conflicts.
The Prompt API allows developers to send natural language requests to Gemini Nano in the browser for various applications. It requires a minimum of 22 GB free space, unlimited data, and Windows 10 or 11, macOS 13+, or Linux operating systems.
Branimir, a Cassandra committer, shares his background and experience working on software infrastructure. He started with digital signals processing and natural language processing before joining IBM and contributing to Cassandra for over a decade.
A developer shares their experience with a side-project that failed to meet expectations, but still provided valuable learning experience. They realized that success is a matter of perspective and that abandoned projects can be a great way to experiment and learn.
SentinelLABS uncovered a 2005 cyber sabotage framework, fast16, targeting high-precision calculation software with a kernel driver that patches code in memory to tamper with results. The framework was designed for strategic sabotage, introducing small but systematic errors into physical-world calculations.

To ensure creativity and focus, I use three constraints: a one pager that captures my north star, a core piece of technology that supports my product, and a defining constraint that gives my product identity. If a project fails to meet any of these constraints, I don't build it, as it will likely result in a complex, bloated, or unidentifiable product.
