The technology behind GitHub’s new code search (via) I’ve been a beta user of the new GitHub code search for a while and I absolutely love it: you really can run a regular expression search across the entire of GitHub, which is absurdly useful for both finding code examples of under-documented APIs and for seeing how people are using open source code that you have released yourself. It turns out GitHub built their own search engine for this from scratch, called Blackbird. It’s implemented in Rust and makes clever use of sharded ngram indexes—not just trigrams, because it turns out those aren’t quite selective enough for a corpus that includes a lot of three letter keywords like “for”.
I also really appreciated the insight into how they handle visibility permissions: they compile those into additional internal search clauses, resulting in things like “RepoIDs(...) or PublicRepo()” # 6th February 2023, 6:38 pm
AI assisted learning: Learning Rust with ChatGPT, Copilot and Advent of Code
I’m using this year’s Advent of Code to learn Rust—with the assistance of GitHub Copilot and OpenAI’s new ChatGPT.
[... 2661 words]Introducing stack graphs (via) GitHub launched “precise code navigation” for Python today—the first language to get support for this feature. Click on any Python symbol in GitHub’s code browsing views and a box will show you exactly where that symbol was defined—all based on static analysis by a custom parser written in Rust as opposed to executing any Python code directly. The underlying computer science uses a technique called stack graphs, based on scope graphs research from Eelco Visser’s research group at TU Delft. # 9th December 2021, 11:07 pm
