Bobbin is a read - only, API-only AppView for Tangled. It serves the read side of the sh. tangled.* lexicons over XRPC, so a client can render git repositories, issues, pulls, comments, stars, & follows, without having to ping N PDSes for their data. It has no permanent storage.
Everything it knows is only ever in RAM and gets backfilled from upstream every restart.

So I've been working on an atproto-native database on foundationdb that automatically generates simple value indexes and graph-edge indexes based on lexicons. We're currently validating perf of the design. The query language design has been an interesting challenge. I'm not totally sold yet but

### Posts carol liked, in English, newest first (path + body + order)

I mean, basically yeah! This is the atproto database I've been playing with lately.

atdb.query({
from: {collection: "app.bsky.feed.post"},
where: [{eq: {field: "/lang", value: "en"}}],
order: {by: "@indexedAt", dir: "desc"},
limit: 50
})

> 4. For every code change merged, the probability of a production incident has more than tripled. This is the kind of claim that people are probably most riled up about. I have genuine questions about this claim, and I think it's worth pointing out that this report is a sales pitch for an AI saas

How we isolated the signal
• Standardized all metrics per company to remove inter-organizational variance.
• Used Spearman's rank correlation (ρ) to assess relationships between metrics and AI usage.
• Reported only metrics with data from at least 6 companies and statistically significant correlations
(p-value < 0.05).
• For each team, we calculated the percent change in metric values between the two quarters of
lowest AI adoption and the two quarters of highest AI adoption within the observation period.
• Excluded outlier data and metrics with insufficient historical coverage.

stuff like github's reported languages. topline it shows stuff like php and ruby disappearing, and if you look at the more niche languages like elixer theyre failing to get off the ground
