The author discusses the limitations of traditional notebooks like Jupyter, which create hidden state, leading to issues with reproducibility. To address this, they present marimo, a new approach where each notebook is modeled as a directed acyclic graph (DAG) to control the flow of variables. This allows for reproducibility and maintainability, as marimo notebooks are […]

Memory leaks can be a nightmare, especially in high-traffic production apps. Ben Sheldon shared his experience debugging a memory increase in a decade-old Rails app. After suspecting telemetry changes, the team used rbtrace to dump Ruby’s memory heap and sheap to analyze it. They discovered an Array holding references to over 32,000 Event objects, causing […]
If you’re suddenly being bombarded with requests to prove you’re not a robot, fear not – it’s just us keeping a watchful eye on potentially suspicious activity from your computer network. To regain access, simply confirm you’re human by clicking the designated box. If you’re still scratching your head as to why this is happening, […]
The CORDIC algorithm is a brilliant way to compute trig functions on low-power hardware without requiring fancy floating point units or lookup tables. By breaking down complex operations into simple additions and bit shifts, CORDIC combines vector math, trigonometry, and computer science elegantly. It’s ideal for embedded systems like microcontrollers and FPGAs, offering a precise […]
PeaZip is an open-source file compression and encryption software designed to bridge the gap between GUI and CLI applications. It offers unique features like CLI-friendly scripting, two-factor authentication for encryption, and support for less common compression formats like zpaq and brotli. The software is cross-platform, supporting over 200 archive formats and strong encryption methods. PeaZip […]
Naviaux and his team at the University of California San Diego School of Medicine have uncovered key metabolic changes that occur in children with autism, shedding light on new early detection and prevention strategies. Their research suggests that metabolic differences related to the cell danger response may play a significant role in the development of […]
A team of researchers in Japan has developed a new type of deformable mirror for X-ray microscopes that can achieve high resolution by correcting the wavefront shape. The mirror, made of a single crystal of lithium niobate, can adjust its shape to improve image precision at the atomic level. This breakthrough technology, created by Satoshi […]
Jacinda is a functional pattern sifting language, described as a smaller version of AWK, powered by Rust’s regex library. It is a command-line tool for summarizing and reporting data. Jacinda can be used to manipulate Unix record separators and extract specific information from tools like otool and printenv. Although it has some missing features and […]
