Thank you for having me once again! ^_^

Race conditions are often not given the attention they deserve. @dtinth joined us from Bangkok for the 2nd time to share another insightful talk on coding practices, this time on managing these race conditions. https://t.co/kOYhneTan4

@mattpocockuk What works well for me is doing acceptance-/tdd (ATDD) at the unit level.

1. Grill on acceptance criteria + example
2. Translate the English example as closely as TypeScript syntax allows (pictured)
3. Agent implements the units, along with the tester DSL informing future tests

[Thai Pangsakulyanont @dtinth]

@johnny5feels @mitchellh Nowadays much easier: Ask a coding agent to compare changes between the originally-forked version and latest, then "port" in the new performance improvements.

[Thai Pangsakulyanont @dtinth]

@mattpocockuk @GergelyOrosz We run a bridge between Discord and a coding agent harness (OpenCode here), now we can have collaborative grilling sessions.

The bridge just pass along thread events from Discord (as JSON - the model can deal with it) and sends back model progress/output.

[Thai Pangsakulyanont @dtinth]

@mattpocockuk Yes, doing it before agents and now with agents. I don't see it as mutually exclusive to PRs though; we still use PRs but feature flags allows our PRs to be small.

Known as "scaled trunk based development", with feature flags as an enabler - https://t.co/QO4aFsiaiX

@thdxr It would depend on whether the server can hot-reload config.

Without it: I change opencode.json → Restart OpenCode → stale config → ??? → figured out it's the daemon that needs restarting, but how? (status quo better)

With hot-reload, having a bg server seems better.

Now that ACM Digital Library is Open Access, everyone can now read the Elysia paper

[SaltyAom @saltyAom]

Elysia research paper is now on ACM digital library talking about Elysia's "kinda compiler"
It's a 6 page so we can't cover all the stuff but it includes the idea, the basic implementation, and the benefit

[Thai Pangsakulyanont @dtinth]

@kumard_3 @JorisvanHaeren @localhost_5173 I accidentally made bugs like this too, even when I used React since 2014—can confirm it's very subtle.

It's a small app; no CPU spike when rerendering. It’s Firebase so everything goes thru WS; no request spamming.

I only noticed when Firebase bills me $10/day for bandwidth.

@saltyAom I really enjoy deploying Elysia-based services to @deno_land Deno Deploy as a Playground.

Deno automatically fetches the Elysia dependency and deploys it, so I can quickly build adhoc endpoints.

@mattpocockuk I define an interface with all base services like:

interface Ctx {
fs: typeof import('node:fs/promises')
// others…
}

Functions that participate in DI take a subset of `ctx` as 1st parameter:

async function loadArticle(ctx: Pick<Ctx, 'fs'>, …)

[Thai Pangsakulyanont @dtinth]

@JamesIvings My guess would be memoizing an unbounded number of things without clearing? e.g. using a Map/object instead of WeakMap / lru-cache / external cache store

[Thai Pangsakulyanont @dtinth]

@saltyAom Congrats on the new release!

I reported a few regressions.

Btw I’m taking my notes about Elysia here based on my use cases, using techniques inspired by snapshot testing, so I know when new releases caused something to crash:

@saltyAom benchmark

[Thai Pangsakulyanont @dtinth]

@saltyAom this also gives a random 16-digit hex, but about 2x faster and 2x shorter

The result of listening to every tech influencer

[SaltyAom @saltyAom]

Deno 2.0 blog announcement mentioned that Deno HTT is faster than Bun

Following the blog they reference, there were no repo nor code we could run on our end

I edit my benchmark to include Deno and the result was Bun is significantly faster unlike the claim?

@nucknyan @mattpocockuk oh you’re right!

the spec does specifically mention UTF-16:

　“each element in the String is treated as a UTF-16 code unit value.”

i guess i tried to convey that ECMAScript uses UTF-16 for its character-code mapping, but not necessarily its encoding format.
