Say Goodbye to FFmpeg Command Lines: Natural Language Video Processing

2025-07-23

wtffmpeg is a command-line tool that uses a local Large Language Model (LLM) to translate plain English descriptions of video and audio tasks into executable ffmpeg commands. No more sifting through Stack Overflow and documentation – simply describe your task in natural language, and wtffmpeg generates the corresponding ffmpeg command. It features interactive execution confirmation, GPU acceleration, and customizable LLM models. The tool runs locally, requiring no internet connection, but you need to download an LLM model and install dependencies.

OSS Rebuild: Rebuilding Trust in Open Source Package Ecosystems

2025-07-22

Google's new OSS Rebuild project aims to strengthen trust in open-source package ecosystems by reproducing upstream artifacts. Responding to the rise of supply chain attacks, OSS Rebuild automates the creation of declarative build definitions for PyPI, npm, and Crates.io, providing SLSA provenance meeting SLSA Build Level 3 requirements without publisher intervention. It offers build observability and verification tools, along with infrastructure definitions for organizations to run their own instances. By rebuilding, generating, signing, and distributing provenance, OSS Rebuild helps detect various supply chain compromises like unsubmitted source code, compromised build environments, and stealthy backdoors, enhancing package trust and accelerating vulnerability response.

Unexpected Inconsistency in C# Records: A `with` Operator Gotcha

2025-07-22

The author discovered an unexpected inconsistency when using C# records. When updating records containing derived data with the `with` operator, the derived data isn't recalculated, leading to inconsistencies. This stems from the `with` operator not calling the constructor but instead using a copy constructor to create a copy and then modify properties. Several solutions are proposed, including avoiding `with` on complex records, writing a Roslyn analyzer to detect the issue, using `Lazy` for deferred property computation, and requesting a language change. This post highlights a potential pitfall in C# records, cautioning developers about using the `with` operator, especially with derived data.

Static Linking Nightmares: An SDK Provider's Lament

2025-07-22

As an SDK provider, we're expected to offer both dynamic and static linking options. Static archives (.a) seem simple, but are fraught with peril. The linker's default behavior atomizes the archive, picking and choosing object files, potentially leading to bloated binaries and runtime crashes due to constructor/destructor ordering issues. While -Wl,--whole-archive helps, it forces inclusion of all library files, regardless of need. Namespace clashes within static archives also pose significant problems. To overcome these challenges, the author proposes a new "Static Bundle Object" (.sbo) file format. This would offer the symbol visibility guarantees of a shared object, avoiding many linking issues, even if it means sacrificing some potential binary size optimization. The author argues that a stable linking ecosystem is worth the trade-off.

Booting Erlang on 16MB: A GRiSP Nano Achievement

2025-07-22

The GRiSP Nano team achieved a significant milestone by successfully booting an Erlang virtual machine on a 16MB STM32U5 microcontroller. Initially aiming for 32MB, a CPU erratum forced a reduction. Through a series of optimizations, including removing the crypto library, aggressive compile/link flags, stripping BEAM files, RTEMS system tweaks, and allocator surgery, they overcame memory constraints. Disabling Unicode temporarily allowed them to reach the Erlang shell prompt. Future plans involve relocating code to internal RAM/Flash, shipping lightweight kernel/stdlib variants, adding energy-aware boot logic, and developing a Unicode-light build.

This website utilizes Anubis v1.20.0, an anti-scraping system employing a Proof-of-Work (PoW) mechanism similar to Hashcash to combat aggressive web scraping by AI companies. The overhead is negligible for individual users but significantly increases costs for large-scale scrapers. This is a temporary solution; future improvements will incorporate fingerprinting and headless browser detection to refine user identification and reduce the need for the PoW challenge. Ensure JavaScript is enabled in your browser and disable plugins like JShelter which may interfere with Anubis.

Gentoo's Ingenious Solution to Perl Versioning Chaos

2025-07-21

Gentoo's Perl package versions don't directly match upstream versions due to Perl's inconsistent versioning schemes. Upstream uses two incompatible methods: treating versions as floating points (making 1.1 and 1.10 equal) and using 'v' prefixes or multiple dots. Gentoo elegantly solves this with the `Gentoo::PerlMod::Version` module, which translates upstream versions into a consistent scheme, preserving sorting order and avoiding conflicts. The module converts floating-point versions into a 'v'-like format before comparison, ensuring compatibility while preventing version collisions and maintaining correspondence with upstream.

10x Zsh Startup Time Improvement: From 5 Seconds to 0.5 Seconds

2025-07-21

The author's Zsh shell startup time was a sluggish 5 seconds. Using the built-in `zprof` profiler, they identified Oh-My-Zsh, compinit, and syntax highlighting as major bottlenecks. By disabling Oh-My-Zsh auto-updates, optimizing the compinit cache, tweaking Spaceship prompt settings, and optimizing plugin order, startup time was reduced to 0.5 seconds—a 10x improvement! The post includes before/after config comparisons and lists alternative optimization options like Starship prompt and the Zinit Zsh framework. Ultimately, the author advocates for optimizing only if necessary, as a faster shell is achieved with minimal effort.

How Top Programmers Use LLMs to Supercharge Productivity

2025-07-21

Veteran programmer antirez shares his 18-month experience using large language models like Gemini 2.5 PRO and Claude Opus for coding. He argues that current LLMs are best used as powerful assistants, not as standalone project completers. By clearly describing problems and iterating effectively, LLMs can help eliminate bugs, explore ideas faster, engage in pair-design, and even learn technologies outside one's expertise. However, antirez stresses the importance of providing ample context, choosing the right model, and maintaining control over the code, avoiding reliance on automated agents. Only then can code quality be assured and efficiency maximized.

OpenBSD Major Update: FILE Object Structure Becomes Opaque

2025-07-21

OpenBSD recently underwent a significant system update making the internal structure of the FILE object in its standard input/output library opaque. This means programs can no longer directly access the internal structure of the FILE object. The change is far-reaching, affecting libc and many libraries that depend on it, including libcrypto, libtls, and libssl. To ease the transition, some helper symbols are temporarily retained but will be removed in the future. Developers are strongly encouraged to use a snapshot upgrade to avoid potential problems.
