Simon Willison built a Newsletters page for his blog almost entirely by speaking to the ChatGPT desktop app in Codex voice mode (using GPT-6 Astra High) while running a local development server. The feature adds a new Django model, migration and admin configuration plus imports for four sources: recent Substack items via RSS, older Substack items via an undocumented API (paginated after research), monthly newsletters from a public GitHub repo, and a private sponsors-only newsletter from a private repository. The public site exposes /newsletters/ and by-year archive pages, shows newsletters on day and month archive pages but not on tag pages or the homepage, links weekly Substack posts back to Substack, gives archived monthly newsletters their own pages, and integrates results into the site search.
Voice interaction handled most of the work - clarifying prompts, code edits, and preview-driven tweaks - until private-repo access and import mechanics required switching to the keyboard. Willison opened a branch and PR generated by Codex, reviewed the code, replaced a Git-subprocess import with an API-based import, made display tweaks, and completed deployment. He concludes voice-driven coding with a visual preview is powerful for multitasking and high-level development, though he still prefers typing for detailed debugging and sensitive tasks like managing API keys.

Eurydice is a tool that compiles Rust code into readable C code, facilitating interoperability and analysis. It aims to make Rust's low-level details more accessible by translating it into a familiar language for developers and tools. (lwn.net)
Prime Agent has been rewritten in Rust to improve speed, reliability, and maintainability, handling over 2,000 agents across 10,000 Prime Sandboxes. Rust's performance, concurrency, and compile-time guarantees enable faster operation and fewer bugs compared to the original TypeScript version. (primeintellect.ai)
Users share their first commands on a new server, such as checking system info or listing files. Common commands include ls, nproc, lsb_release -a, and uname -a. (news.ycombinator.com)
Researchers analyze git commit hashes to identify rare patterns based on specific word and sequence criteria. They categorize hashes into tiers like common, rare, and mythic, using pattern matching and GPU computation to find the rarest hashes. (engineering.finchlegal.com)
Python 3.15 introduces new features such as explicit lazy imports, frozendict and sentinel built-in types, and a dedicated profiling package. It also includes numerous module improvements, optimizations, and deprecations to enhance performance and usability. (docs.python.org)
Kotlin was ported from Rust's Campfire to the JVM in one day, matching or exceeding Rust's performance in benchmarks. The improvements resulted from architectural changes rather than language speed, demonstrating that attention and optimization influence performance as much as the choice of language.
