Can We Trust Search Engines with Generative AI? A Closer Look at Bing’s Accuracy for News Queries (via) Computational journalism professor Nick Diakopoulos takes a deeper dive into the quality of the summarizations provided by AI-assisted Bing. His findings are troubling: for news queries, which are a great test for AI summarization since they include recent information that may have sparse or conflicting stories, Bing confidently produces answers with important errors: claiming the Ohio train derailment happened on February 9th when it actually happened on February 3rd for example. # 18th February 2023, 6:09 pm

Last week, Microsoft announced the new AI-powered Bing: a search interface that incorporates a language model powered chatbot that can run searches for you and summarize the results, plus do all of the other fun things that engines like GPT-3 and ChatGPT have been demonstrating over the past few months: the ability to generate poetry, and jokes, and do creative writing, and so much more.
[... 4922 words]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
