how do y’all iOS users not go absolutely crazy jumping between the number and letter layers of the keyboard. the keyboards on android are so much better, why is apple not copying this shit. I want to switch back to iOS but the keyboard sucks ass

man, people get really upset when you advocate for reading the code you merge into main 😅

I don't know how to program without reading the code knowing you'll inevitably have to explain to a customer "sorry we lost your data (or something), the root cause was X but Claude said the code was fine".

I can't believe I'm saying this but I think Gemini 3.7 flash is my favorite model. imo its the perfect human in the loop model. It's not the smartest, nor the best on benchmarks, but it writes good code and is fast enough and doesn't get distracted on side tangents

For those that still like to think about code conceptually I highly recommed this nicely animated video. Honest/dishonest functions feels like a much better framing than pure/impure and something I haven't thought as much about. https://youtu.be/2OMRWPOSw9s

Another fun harddrive quote I think about regularly is one from my @bcantrill talk: "the disk is actually aware of the fact it is cheating physics all the time" https://youtu.be/fE2KDzZaxvE hardware engineering is damn near witchcraft

GPT 5.6 Sol from @OpenAI is 50% off through @Cloudflare AI Gateway unified billing for the next month. What will you build? https://developers.cloudflare.com/changelog/post/2026-08-19-gpt-5-6-sol-discount/

Apache DataFusion Community Showcase Vol. 4 📣 Thursday, August 20th at 9:00 am PST on Zoom - featuring @jeromeschneider of Cloudflare R2 SQL and Tobias Schwarzinger of RDF Fusion. 1) "Building R2 SQL on DataFusion" R2 SQL is Cloudflare's serverless, distributed, analytics query engine for Iceberg catalogs. This talk presents how R2 SQL integrates @ApacheDataFusio and Datafusion Distributed over Cloudflare infrastructure, and some of the challenges faced to make it work. 2) "Graphs, Piecewise Functions, and Apache DataFusion" Tobias' reserach group at @tu_wien investigates the use of graph data in IoT use cases. Often, you find that you must combine knowledge about the system (which is stored in graphs) with the run-time data from sensors in a single query. To enable both types of data to exist within a single query engine, RDF Fusion implements SPARQL, while PolyArrow implement querying over "piecewise signals" (i.e., instead of treating a time series as points the interpolation strategy is part of the data model). Both are prototypes based on DataFusion. This talk will cover the fundamentals, then how we build on DataFusion, some workarounds that we need to employ, and give an outlook on how we could combine these two efforts. cc @CloudflareDev, @andrewlamb1111, @InfluxDB Join us!

gotta say, people building GitHub competitors / git storage services are killing it with the names Artifacts Cursor origin Netlify source code[dot]storage All bangers

one of my favorite things about working at cloudflare is the humbling reminder that i write typescript for a living and there and engineers here that do insanely cool work like this that i get to read and learn from

Your users have suddenly acquired the ability to speak code into existence. What if your app gave them a safe place to run it? https://jeremymorrell.dev/blog/extensible-software-in-the-age-of-llms?s=1

at this point I want a model that can write great code with a 60% deep swe score more than a model that scores 80% with slop all these models require so much feedback to avoid the code horribly structured

what if @sentry actually calls you and you prompt the fix over the phone could be the move

Workers + Access just got much better: 🔑 Enable Access on a specific Worker (covering all preview and /or production domains) 🔑 Enable Access on account so all new Workers are automatically covered 🔑 See who's accessing your app from ctx.access 🔑 Test in local dev
