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

> which isn't saying that much

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.

https://rockwotj.com/blog/async-wasm-in-seastar/ - been meaning to write about this for a long time. Thanks for the nudge :)

I have done this integrating wasmtime into a a C++ seastar.io application. I’ll have to write a post about it

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.

networking costs are so high in AWS I doubt this makes sense

It’s so hard to actually benchmark languages because it so much depends on the dataset, I am pretty sure with simdjson and some tricks I could write C++ (or Rust) that could top the leaderboard (see some of the techniques from the billion row challenge!).

tbh for silly benchmarks like this it will ultimately be hard to beat a language that compiles to machine code, due to jit warmup etc.

It’s hard to due benchmarks right, for example are you testing IO performance? are OS caches flushed between language runs? What kind of disk is used etc? Performance does not exist in a vacuum of just the language or algorithm.

With the new GC I really love the trend of understanding memory bandwidth is the bottleneck for many things and the combination of locality and SIMD is a big performance unlock.

you also get a very slimmed down interface that is usually way faster to load. one of the reasons I love HN is that it is super snappy to load and isn’t riddled with dependencies that take forever to load and display. Snappy UIs are always a breath of fresh air.

Isn’t codex open source and you can just go read what they do?

I have read the gemini source and it’s a pretty simple prompt to summarize everything when the context window is full
