Snowpack is a system that uses random, immutable 64-bit domain separators in the IDL to prevent domain separation bugs in cryptographic data. It ensures canonical encodings and guarantees that the sender and receiver agree on the type of data, making it a simple and effective solution for serialization of inputs to cryptographic functions.
The data scientist role is not over, but its work has shifted from model training to experiment setup, debugging, and metric design. Data scientists still play a crucial role in evaluating AI systems and driving application-specific metrics.
git_bayesect uses Bayesian inference to identify commits introducing changes, with greedy minimisation of expected entropy and Beta-Bernoulli conjugacy. It sets priors based on commit messages and diffs to handle unknown failure rates.

InspectMind AI is building an AI Plan Checker to review construction plans and find issues before building. The company is seeking a software engineer to improve accuracy and ship features quickly using AI coding agents.
The author is a former fan of Scott Alexander, but now disagrees with his views on social issues and public policy. The author criticizes Alexander's reliance on data and graphs, which they call "The Church of Graphs," and argue that this approach can lead to an impoverished worldview.
A public benchmark for evaluating whether AI agents can complete real workflows. Compare model performance and cost-effectiveness on real agent tasks.
User is using JAX for GPU accelerated graphics rendering with Signed Distance Functions (SDF) and auto-vectorization. They're exploring its potential for higher-level DSLs and geometric algebra.
Meta is releasing an AI model for designing concrete mixes, Bayesian Optimization for Concrete (BOxCrete), to help US producers use domestic materials. The model improves mix design speed and sustainability, reducing US reliance on imported cement.
Windows 95 had a backup directory to prevent installers from overwriting system files. It checked for mistakes after installers finished and restored the original files if necessary.
Artemis II is NASA's first crewed mission under the Artemis program, launching from Kennedy Space Center in Florida. It will test the Orion spacecraft's life support systems and lay groundwork for future crewed missions.
CERN engineers developed super-charged karts to speed up work in the Large Hadron Collider tunnel during major works. The karts, inspired by nursery school children's designs, will replace bicycles and enable faster travel through the 27-km tunnel.
The Unicode Standard provides a superset of most character sets in use around the world, allowing for over one million code point slots and enabling simultaneous representation of various scripts and languages. Character encoding, such as UTF-8, UTF-16, and UTF-32, maps abstract characters to numbers for manipulation in a computer, and proper handling of character boundaries is crucial for ...
Zerobox is a tool for credential injection and sandboxing processes, allowing secrets to be passed to specific hosts without being visible to the process. It provides features like environment variable inheritance, network proxying, and restricted access to user data and system libraries.
SpaceX has confidentially filed for an IPO with a potential valuation of $1.75tn, with the listing expected to take place as early as June. The company's financial disclosures will be reviewed by regulators before being made public, revealing details of its finances and valuation.

A mysterious Persian-language numbers station started broadcasting on February 28, about 12 hours after US and Israel began bombing Iran. The signal was jammed on March 4, leading to speculation about its origin and purpose.
BGP security issues allow malicious actors to hijack devices, causing widespread problems. RPKI signing of Internet routes can improve BGP security.
A "Crackpot Index" for marketing-speak is proposed to assess the validity of company claims. The scoring system deducts points for lack of citations, misuse of scientific terms, and vague or unfalsifiable claims.
Pratt parsing is a method for parsing expressions with varying precedence by walking back up the spine of the tree when a transition operator appears and building a left-leaning subtree. The Pratt parser uses a recursive descent parser with a call stack to build the tree, and it handles left-associative and right-associative operators by adjusting their left and right binding powers.
At 50 years, it’s only natural to look back. But Apple has always looked forward, building tools and delivering experiences that enrich people’s lives. As we celebrate how far we’ve come, we’re inspired by where we’ll go — together.
This tutorial was written for all those who are interested in programming embedded systems and who would like to explore the idea of using Ada and SPARK in systems based on ARM Cortex-M microcontrollers.
Greenland sharks are the planet's longest-lived vertebrates, with some estimated to be between 272 and 512 years old, and have been swimming silently through the northern seas for thousands of years. Despite their slow metabolism and unpleasant appearance, these sharks are a symbol of hope and endurance, and will likely outlast human civilizations and witness future transformations on Earth.
