User wants to convert a video file using ffmpeg, selecting various options such as format, size, speed, and more. User installs ffmpeg on different operating systems.
Interactive React components for creating network diagrams, fiber networks, and rack infrastructure visualization.
uv is faster than pip due to dropping legacy support and exploiting modern standards. Its speed also comes from design decisions like static metadata and no code execution to discover dependencies.
To enable Brainstorm Mode in VSCode, install two AI agents from the settings panel, such as Claude Code and Gemini, and let them work together to tackle problems. This mode allows multiple implementation approaches and lets you choose your preferred path.
mruby is a lightweight Ruby implementation with Ruby 3.x compatible syntax and features, except for pattern matching. It can be linked, embedded, and compiled into byte code using tools like mirb, mrbc, and mrbtest.
Obscure tape finds and their stories
Last year, Lemire wrote about an optimized variation of the Euclidean algorithm for computing the greatest common divisor of two numbers, called binary Euclidean algorithm or Stein’s algorithm. It’s a best-of-class implementation, though it’s currently only used by libc++. The post also briefly mentions the extended Euclidean algorithm, a related algorithm most often used to compute the ...

User thinks text is the most powerful and effective communication technology due to its flexibility, precision, and efficiency. They recommend always choosing text over other forms of communication like images or video.
Lean 4 + Mathlib has formally verified junk theorems that are surprising to mathematicians. These theorems arise from type theory and Lean's design decisions.
The user discovered new things in 2025, including books, podcasts, games, and programming languages, and reflected on their experiences with systems thinking, fiction, and Clojure. They also discussed their plans for 2026, including non-technical writing, publishing a card game, and exploring new technologies.
The team released a QNX 8.0 desktop environment with self-hosted compilation, simplifying Linux app porting and development. It includes a QEMU image for testing, with tools, samples, and a web browser.
Using git as a database is appealing due to its version history and review workflow but it inherits filesystem limitations and becomes slow with large repositories. Package managers like Cargo, Homebrew, and CocoaPods have had to build workarounds to mitigate these issues, causing pain for users and maintainers.
The ReadME Project helps open source developers increase their chances of encountering good luck by publishing their work and building a reputation. By doing so, they can increase their "Luck Surface Area" and catch opportunities as they flow by.
Got two minutes? Listen to Colin explain the strange effects of Lilliputian mushrooms, including the sudden appearance of tiny people! The Museum is full of more than 1.6 million objects and countless stories. We are constantly writing and recording these for our online audience, sharing blog posts, videos, and podcasts about the latest scientific research happening at NHMU.
User learned about cronjobs in the early 2000s and initially found them complex. They recently discovered that adding arbitrary checks to crontab is easy using the POSIX 'test' command.
Memory leaks in Python are often straightforward to diagnose. Just look at RSS, track Python object counts, follow reference graphs. But leaks inside C extension modules are another story. Traditional memory metrics such as RSS and VMS frequently fail to reveal them because Python's memory allocator sits above the platform's native heap (see pymalloc). If something in an extension ...
EFF has raised concerns about AI-written police reports being unproven, untransparent, and irresponsible. Two states, Utah and California, have passed bills to regulate AI police reports, requiring disclaimers and disclosure of AI-generated content.
The user discovered onemillionscreenshots.com, a tool for web discovery, but found its reliance on popular websites from Common Crawl limiting. They're working on tools for small web discovery and used self-organizing maps (SOMs) for dimensionality reduction.
Lewis Carroll's Dodgson condensation method calculates determinants by repeatedly condensing a matrix. It's efficient, easy to teach and parallelizable, but has features that make it practical for machine computation.
witr is a tool that shows why a process is running by building a causal chain. It identifies the PID and explains its ancestry, user, working directory, and environment details.
Autovectorisation is a compiler optimization that uses SIMD (Single Instruction, Multiple Data) to process large arrays efficiently. With the right flags and data layout, compilers can turn one-at-a-time loops into batch-processing powerhouses.
Researchers at Carnegie Mellon University developed a new lens that can bring an entire scene into sharp focus at once, regardless of distance. The "computational lens" uses a hybrid of optics and algorithms to adjust focus differently for every part of a scene.
Physicists are still trying to fully understand the proton, a quantum mechanical object that exists as a haze of probabilities until an experiment forces it to take a concrete form. The proton's secrets keep tumbling out, with recent discoveries including the presence of charm quarks that are heavier than the proton itself.

Author is implementing a POSIX compliant OS in Rust without external libraries, documenting the process and code. The book assumes basic programming knowledge and some assembly knowledge.
Researchers fine-tuned their latest model to tackle 5 Robot Olympics challenge tasks, achieving gold medals in 3 categories and silver medals in 2. The tasks required physical manipulation and interaction, highlighting the difficulty of building machines that can interact with the physical world.
So after our previous reviews (that started mainly around RISC-V since we are really interested in this new architecture) of SBC, we continue to review what’s available these days in the world of small, versatile computers. Today this is going to be about the OrangePi 6 Plus, following our previous review of the OrangePi 5 ultra board. This is NOT a super small, credit card format SBC. We are ...
Xcc700 is a small, portable C compiler for modern platforms, including esp32, with limited features and no error checking. It can compile and run on esp32 or cross-compile for other platforms, with a self-hosting version available for experimentation and extension.
