some slight progress, especially visually
i kind of get why people dont go for realistic speeds and wind though, this feels SLOW. getting to an island takes me ages

started a little game project in godot: a pvp pirate game for phones
i want it to feel like piloting a ship: rotating the wheel controls the rudder that eventually turns the ship
spyglass being useful to look around you quickly etc
lets see where this takes me!

I want to like you @opencode.
you look good, you perform well, you allow me to choose models and write ts plugins
but sometimes you make it hard

I remember @theo being very critical about how slow Arc was to open downloads, but T3 Code’s diff viewer is the most stuttery experience i’ve ever had in software
many such UX nightmares in this app
codex here I go

toggle buttons move around: if i click on "show diffs" and then again without moving my mouse, i actually hide whitespace changes instead of closing it

we’re here discussing how agents should be writing most of the code

had a really fun day yesterday working with AI. needed to design an API that is based off of an existing legacy product.
instead of jumping straight to code, i had claude code research the original codebase and describe the minimum surface we can implement
then used @mattpocockuk ’s grill-me skill to run through each decision. I got asked 32 questions and some i had to go and research before answering
finished at end of day. gave it to claude code to implement with some specific subagents to verify the code as I left the computer. woke up to a decent implementation. now im just reading and polishing!

ive been using claude code on my phone a lot to create quick apps and games
i create a repo in @github (the app doesnt support creating a repo sadly) then link it to claude code and start prompting
deployed to @Cloudflare workers and setup a subdomain all on my phone too (also not the most pleasing experience, broken UI everywhere pls fix @nandafyi)
made this one while hanging out with a few friends last weekend: caveman.frederic.ooo/
it’s an in-person party game, it worked really well!

companies add big chat inputs everywhere and forget the leaves of their UX
@github HERE is where i want a smart field. this can be a simple rag that would unlock so much

Modern DRAM is based on a brilliant design from IBM.
But, we're still paying for a latency penalty that's existed since the 60s!
In this video, I'm introducing my research project (Tailslayer) that immensely reduces p99.99 latency on traditional RAM!
By implementing a hedged read strategy taking advantage of (undocumented!) channel scrambling offsets, I've gotten as much as 15x reductions in tail latency.
The technique works across Intel, AMD, Graviton, DDR4, DDR5, x86, ARM, you name it.
Check out the C lib I wrote, watch the video, and try it yourself!

you think everyone is harnessing agents and coding 10 times faster
whereas the average engineer is still discussing this
this is from a tech lead at a big company
