PSOS is a secure operating system designed using the SRI Hierarchical Development Methodology (HDM) with a capability mechanism for access control. The capability mechanism provides a simple and uniform way to manage access to objects, with capabilities serving as names or tokens for all objects in the system.
Automated data broker opt-out runner for macOS. Removes your personal information from 500+ people-search sites and data broker databases on a monthly schedule — with CAPTCHA solving, persistent state tracking (so completed opt-outs aren't resubmitted every run), and an iMessage notification when done. # 1. Clone the repo git clone https://github.com/stephenlthorn/auto-identity-remove.git ...
GenCAD is an image-conditional CAD model that generates 3D CAD and its command history. It uses a strong representation learning framework for multiple modalities of computational engineering designs.
The debate on consciousness is fueled by human fear of being part of the natural world, but consciousness is a natural phenomenon that can be understood through science. Our soul or spiritual life is consistent with fundamental physics, and we can safely speak of it without introducing dualism.
Scientists discovered a new clathrate material within trinitite, a glasslike substance formed from the Trinity nuclear test. The clathrate's unique structure was created under extreme conditions, similar to those found in nuclear explosions and meteorite impacts.
NASA's Voyager spacecraft run on assembly language written in the 1970s, with a small team of engineers in their 80s struggling to find replacements. The team faces a succession problem due to the unique skills required to maintain the spacecraft's custom hardware and outdated software.
Debian 12 Bookworm runs on Doogee U10 tablet without bootloader unlock using rkdebian build system. It supports local LLM inference on RK3562 NPU and has functional front and rear cameras but needs color calibration.

The author of jank, a Clojure dialect, has created a custom intermediate representation (IR) to optimize jank's performance and compete with the JVM. The author has implemented several optimizations, including inlining, eliminating unnecessary IR instructions, and using tagged pointers to avoid dynamic allocations, which have significantly improved jank's performance in a recursive Fibonacci benchmark.
Semble is a code search library that indexes and searches codebases instantly, using 98% fewer tokens than grep+read. It runs on CPU with no API keys or external services, providing fast and accurate results for agents.
The author argues that AI has lowered the barrier for Level 1 tasks, but not for complex tasks that require architectural judgment. They claim that accusations of "vibecoding" are unfounded and based on a false premise.
ksharp is a K programming language interpreter written in C# with a focus on simplicity and compatibility with K version 3. It supports various features including parsing, evaluation, and .NET integration, with ongoing development and contributions from multiple individuals.
A Prolog programmer should rebel against outdated features, not against the language itself. Using declarative constructs can make Prolog programs more general and efficient.
The code uses 16 bytes of x86 assembly to draw an infinite Sierpinski fractal and generate audio in real-mode DOS. It utilizes video memory as a calculation space and speaker port for audio output.
The text describes a Haskell implementation of category theory concepts, using endo-functors and endo-profunctors to encode equipment and units. It provides definitions for various units and compositions, including Hunit, Vunit, CompUnit, and ConjUnit, with laws satisfied up to isomorphism.
Tesla's Solar Roof failed to meet its 1,000-per-week target, with only 3,000 systems installed in nearly a decade. The company has pivoted to conventional solar panels, abandoning Solar Roof customers with unresolved product issues and poor customer service.
ESP32-S3 N16R8 · ILI9341 IPS 320×240 · LVGL 9.x · CAS Engine · Natural Display V.P.A.M.

Most people remember Alice in Wonderland as a dreamy children's book about a girl, a rabbit, a cat that disappears, and a hatter who hosts a tea party. They forget that the man who wrote it spent the rest of his working life teaching mathematics, and that nearly every famous scene is a joke aimed at his colleagues in the Oxford Senior Common Room. Charles Lutwidge Dodgson was thirty when ...
Two US Navy jets collided and crashed at an air show at Mountain Home Air Force Base, but all four crew members ejected safely. The incident occurred during an aerial demonstration, with no one on the ground hurt, but a nearby road is closed for a multi-day investigation.

A curated list of major CUDA programming books covers beginner to advanced topics, including C++/Python, architecture, optimization, and the latest releases. The list includes 15 high-quality resources, including classic and modern books, with a focus on practical and hands-on learning for NVIDIA GPU parallel computing.
Doron Zeilberger praises lemmas for their significant value in mathematics, often surpassing theorems. A good lemma is applicable, obvious, and aesthetically beautiful, making it a fundamental contribution to the field.
Radio waves are everywhere, used in cell towers, GPS, Wi-Fi, and Bluetooth, and can be easily created at home with a simple radio transmitter made from a grill lighter. A homemade receiver, called a coherer, can detect these radio waves using aluminum foil balls and a button cell battery, demonstrating the basic principles of wireless communication.
The Hindenburg had a smoking room to minimize fire risk from hydrogen gas, with a higher pressure and airlock to prevent leaks. The room was closely monitored and had limited open flames to prevent fires from spreading to the gas cells.
Mezz is a wifi sandbox for inspecting IoT devices in a controlled network. It turns a Linux host into a small isolated network for defensive purposes only.
The user describes how they used Prolog to model the complex mechanics of the Pokémon video game series, finding it to be a concise and expressive programming system for intricate rules engines. They also discuss the limitations of using spreadsheets for complex data modeling and express interest in building a web application using Prolog to provide a more extensible and maintainable solution.
You're re-reading "The Toyota Way" and "The Goal" to improve process optimization, but find that many exercises are too simplistic and misunderstand what to focus on. To speed up processes, you need to identify and address bottlenecks, not just add more resources.
Scientists in Canada discovered that hundreds of gray seal pups are killed by adult male gray seals each year on Sable Island, with the males tearing down to the bone with their flippers. The attacks are likely for added nutrients to boost the males' mating value during the breeding season.
