Three weeks ago PGlite crossed 10 million weekly downloads. Today it just crossed 11 million! It grew 10% in three weeks 🤯

Least flattering camera angle for my bald spot.

Coding agents now handle the manual coding. This means software engineering is shifting upstream - from writing code to orchestrating systems, defining intent, and making product decisions. On the latest episode of The Merge, @ElectricSQL co-founder @thruflo explains why we’re all becoming product managers now… and why managing state for multi-agent systems is the next big infrastructure challenge. We also cover: • Why declarative sync is replacing traditional fetch patterns • How to build reliable multi-agent workflows • The surprising rise of Elixir for agent systems Full episode here ↓

Erlang and Elixir have run some of the most reliable software on Earth for 30 years — without static types. Ep. 18 of @BeamThereDT asks what a type system can actually add to a runtime that already works. With @anne_biene and @duboc_guillaume . 🎧 youtu.be/X_CPDt3PeDE

If you've been waiting for a vote of confidence in TanStack Router (with SSR) this is it! Love seeing awesome people succeed, huge moment for @tannerlinsley and the TanStack team 🚀🎉🫶

new blog post: "Essential Until It Wasn't" What we call programming today is not the same activity it was two years ago. Implementation was essential complexity for 80 years and is now... gone. This has happened many times before and probably will happen again.

Announcement: Soccer to Become America's Official Sport The US Congress and FIFA have just announced a historic agreement: soccer will become the official sport of the United States, rather than American football. To ease the transition, FIFA has approved a four-year Soccer Modernisation Programme. The 2026 World Cup is the pilot. In the first year, a three-minute hydration break will be introduced into each half, purely for the welfare of the players, dividing the match into four segments, which are definitely not quarters. Fans may also hydrate: one factory-sealed 20-ounce bottle each, $12, for security reasons. In the second year, the four segments that are definitely not quarters will be renamed quarters, for clarity. Broadcasters may air commercials during the breaks, at their discretion, and they will exercise this discretion 100% of the time. Play will resume when the commercials are finished. Kickoff times will be 9 AM, 2 AM, or noon in Dallas in July, whatever suits television. Fans abroad will simply stop sleeping, which is fine, because they will be hydrated. In the third year, the clock, which confusingly counts up and never stops, will be corrected to count down and constantly stop, leaving ample time for the referee to jog to a small television at the side of the pitch to review each goal from nineteen angles for seven minutes, and confirm the original wrong call, now backed by evidence. Halftime will be extended from 15 minutes to 45 to accommodate a performance by Shakira, Madonna, BTS and the Muppets at the center of the pitch. Tickets will be priced dynamically, which means the price will rise, dynamically. A limited number of $60 tickets will exist in theory, and a large number of $11,000 tickets will exist in practice. Any empty seats will be officially attributed to fans standing in the concourses, presumably from excitement. By the fourth year, people will be receptive to steps such as abolishing the draw, because "nil-nil" is not a score, it is an apology. The pitch, installed the Tuesday before kickoff, will be narrowed to fit stadiums that were built for a different sport. And since the goalkeeper already uses his hands, which never seemed fair to the other ten players, hands will be phased in for everyone, along with the helmets and pads that will, by then, be necessary. By the 2030 World Cup, the Soccer Modernization Program will be complete. The pitch will be the field, the final will be The Big Game, extra time will be overtime, boots will be cleats, the kit will be the uniform, and the ball, for aerodynamic reasons, will be made slightly pointier at both ends. Soccer will finally regain its original name, Football, and the dream will finally come true: America will love soccer, and the Super Bowl will be the World Cup!

This.

Did someone say @DurableStreams at kernel speed? Who needs user space anyway.

I've been writing a @DurableStreams server in Rust to see how fast it can be. It reaches nearly a million appends per second on a single 4 vCPU box — an order of magnitude faster than current reference server 🧵

@kylemathews @samwillis Very cool.

I fed 289 issues/prs from the TanStack DB repo into a custom SKILL to extract attributes and cluster & then ran each cluster of issues through ChatGPT pro to identify architectural improvements that would solve all the issues. gisthost.github.io/?266a6e0c17a73…

Divide and conquer.

@samwillis 10 million!

10 million downloads a week, with users like Google, AWS, Netlify and Prisma. That's a massive achievement. Well done @samwillis and team 👏

PGlite has passed 10 million weekly npm downloads 🤯 On our blog we spills the beans on what’s driving the growth, and how its used for AI apps, dev tools, sandboxes, CLIs, and test suites from incredible teams like @Prisma, @supabase, @Firebase, @Netlify and @awscloud. 🔗🧵

Launching @supabase-labs/tanstack-db, a TanStack DB collection adapter backed by Supabase. It supports live queries, optimistic mutations, automatic Realtime sync, and is fully typed. Currently in alpha. Try it out, and let us know any feedback!
