We just made history at Hanover Park. @saranormous' @conviction migrated over $1 billion in 7 days. Typically, migrating years of data across a material amount of investments and limited partners takes months. We built a different process. Our AI agents ingest historical data, map investments and entities across source files and cross-check the results. Our accountants review the output and resolve exceptions. Here's how Conviction's Head of Finance described it: “Hanover Park migrated our entire firm in under seven days - faster than we thought possible - providing far better and faster visibility into our financial data than before. We want Conviction to be on the frontier of AI, and this was one of those “wow” moments.” The future of finance starts by making your data legible to AI.

We raised a $27M Series A to replace the spreadsheets and human duct tape behind $100 trillion in global assets. Fund administration is the invisible backbone of private equity and venture capital - and it’s broken. Why? Financial data is scattered, stale, and locked inside legacy providers. Books take forever to close. Basic questions about your own fund take days to answer. So we rebuilt the general ledger, waterfall engine, investor portal, and portfolio management from scratch. One single source of truth for your firm. Our AI agents read emails, propose journal entries, and extract portfolio updates in seconds. Our CPAs review every output. Today, we administer $15 billion in assets - and we’re just getting started. Every fund CFO keeps getting asked: how will you adopt AI? Now you have an answer. Run your firm in real-time with @hanoverpark. –- Excited to partner with Jake Saper at @emergencecap @peterjhebert at Lux, @chadbyers/@pratyushbuddiga at Susa and CFOs at the largest private equity firms to forge this future.

✨What a dream come true!✨ The co-creator of @typescript himself, @ahejlsberg, took some time to look at the Doom project! We also had a chance to chat about other TypeScript topics more broadly - and that video will go live in a few days! DREAM. COME. TRUE.🚀

most people write FizzBuzz or something to learn a new language don wrote a Zig linter… to learn Zig extremely based

I'm a huge Rust fanboy I recently joined @bunjavascript and had 1 month to learn Zig The best way to learn Zig? Write a linter for it. So that's what I did.

If you code in #JavaScript or #TypeScript & are looking for some useful tools, you should check out oxc: a collection of JavaScript tools written in Rust. It provides a parser, linter, formatter, transformer, minifier, resolver, etc. all written in Rust. github.com/oxc-project/oxc
