I actually just started doing this by having Fable roleplay as Jeff Dean and to use Codex as Sanjay driving the implementation and have them go back and forth. Works really well and it’s cool to see AI pair program

This seems really great! I am a long time Bazel fan, but it’s not perfect, and I have always thought there was something simpler than bazel that would give a lot of these kinds of benefits. Having something that works for a hybrid rust/typescript codebase would be great.

I encourage you for you dev command to work with frontend setups like vite so it’s unified with backends and still supports HMR

IIRC (it’s been awhile) this was an optimization that was inspired by someone noticing all of Google spent a lot of time in vDSO using https://research.google/pubs/google-wide-profiling-a-continu... Google generally doesn’t have any (well that I have ever heard of) hard realtime requirements like the high frequency trading or HPC systems do.

Cool stuff thanks for sharing!

Related reading is absl’s linear approximation of gettime from cycle counters, which I thought is a neat trick: https://github.com/abseil/abseil-cpp/blob/351086314d46e73d43...

> Production-grade 17 operation types. 40+ semantic validation rules. Auth, rate limiting, PostgreSQL storage.

Man where in the LLM training data did the “production ready “ come from? That whole list screams AI. Humans want social proof, not a list.

A friend at work used one to predict when our CEO would post in Slack, which is verry entertaining to see if correct.

I mean I also think this move doesn’t make sense, but I always find these type of comments interesting. Do people think they could do better in Mark’s shoes?

Or it’s compiled in the cloud?

One would think it must otherwise there are all these issues with compiling, signing tc if they don’t have xcode installed etc. I would guess it’s some webview wrapper with a layer to expose desktop app functionality

Fundamentally, the "guessing when its your turn thing" needs to be baked into the model. I think the full duplex mode that Moshi pioneered is probably where the puck is going to end up: https://arxiv.org/abs/2410.00037

A category of SaaS companies are cooked in the age of AI - why not just have the perfect purpose built thing instead of fighting bloated enterprise software with a billion customizations and knobs that makes everything complicated?

I am sure they made a bid. The blog makes it sounds like he talked to multiple labs.

Technology does not determine the success of a company. I’ve seen amazing tech fail, and things strapped together with ducktape and bubblegum be a wild success.

Claude is king for agentic workflows right now because it’s amazing at tool calling and following instructions well (among other things)

I thought everyone was just using open telemetry traces for this? This is just a classic observability problem that isn’t unique with agents. More important yes, but not unique functionally.
