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.
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.
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.

The user explains an erosion technique for generating virtual landscapes, which involves using a special kind of noise to produce branching gullies and ridges while allowing fast and GPU-friendly evaluation. The technique has been developed and refined over time, with various approaches and tweaks to address issues such as chaotic distortions, inconsistent gully magnitudes, and non-straight gullies.

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.
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.
A technical issue is threatening the launch of artemis ii on thursday night. the spacecraft will orbit earth until flight day two - when it'll make its way to the moon. only four moonwalkers, now all in their 90s are still alive. john kerry: "we're there to stay" when the crew arrives on the lunar surface. "america doesn't just compete, we dominate," he says
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 ...
A browser strips out social media features designed to keep you scrolling, offering content filters, time limits, and more on-device. It's a tool that puts you in charge of what you see, without accounts, servers, or wellness features.
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.
FreeBSD 13.5 and later versions have a vulnerability in the RPCSEC_GSS module, allowing a remote kernel code execution attack via NFS. The vulnerability is due to a buffer overflow in the svc_rpc_gss_validate function.

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.
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.
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.
