For me it's simple:

1. Assume you're to work on product/feature X.

2. If God were to descend and give you a very good, reality-tested spec:

3. Would you be done faster? Of course, because as every AI doomer says, writing code was never the bottleneck!!1!

4. So the only bottleneck is getting to the spec.

5. Guess what AI can help you with as well, because you can iterate out multiple versions with little mental effort and no emotional sunk cost investment?

ergo coding is a solved problem

Man, if this were true we’d see a crazy, massive explosion of quality products being written, and launched. While we see some use, i don’t perceive an acceleration. In fact, i see a lot of trivial bugs being deployed to prod.

> Humans and LLMs both share a fundamental limitation. Humans have a working memory, and LLMs have a context limit.

But there’s a more important difference: I can’t spin up 20 decent human programmers from my terminal.

The argument that "code was never the bottleneck" is genuinely appealing, but it hasn’t matched my experience at all. I’m getting through dramatically more work now. This is true for my colleagues too.

My non-technical niece recently built a pretty solid niche app with AI tools. That would have been inconceivable a few years ago.

I guess that what people debate on here is what “decent” mean. From my experience, these llms spit out dog shit code, so 20 agents equal 20x more dog shit.

We’re building Chaotic, a high-performance 3D game engine and editor written in Rust. It targets WebAssembly and WebGL2, making it possible to deliver near-native performance and console-quality visuals directly in the browser. On top of the engine, we’re currently developing a multiplayer cozy farming game inspired by Animal Crossing called Fireflies Meadow: https://firefliesmeadow.com/?admin=SkipTheLine&skip=IKnowWha...

Fireflies Meadow isn’t ready for prime time yet, but we’re proud of the progress so far and actively iterating on it.

If you’re interested in the engine, the game, or just want to follow along, feel free to reach out on our Discord: https://discord.com/invite/mHsQayQNdp

I’d be curious to hear your feedback on whether the game is working for you or not.

I never understood double entry bookkeeping and that's where the author immediately loses me again:

Early on after 4th diagram, author includes sentence : "Because every transaction appears twice, once positive and once negative"

There is something so obvious about this to accounting folks that they always make the massive jump without any explanation. The previous diagram absolutely does not have positive and negative for each transaction! In fact, there is 5000 going into banking account and 500+5 coming out of it. Nothing in 4th diagram is obviously the negative of that 5k transaction, to me.

Similarly next sentence is "obviously" false: "If you partition the set of nodes into any two disjoint sets, and add up all of the balances in each set, then the sum for the one set is always the negative sum of the other set" -- the sum of the left two balances is minus five, and the sum of right three balances is 505.

And just like that, I'm completely lost and booted out of yet another accounting lesson without passing the introduction :-(

(fwiw, my experience of reading accounting is broadly the same as reading Plato: "it is obviously true that..." What, no, stop, that's not obvious at all, you gotta do better than that! :-)

Money must flow from a source to potentially multiple destination. Because of that previous fact, you must have at least two postings per transaction (the double in double entry). If you manage to move money correctly without any errors, those postings in that transaction will add up to zero, making it trivial to verify you've done everything correctly without any errors.

Very cute story. It's a shame my cynic brain is telling me "but wolves can't survive off of berries and nuts". Also, I guess fish are fair game in the forest hierarchy. Should have user an omnivore.

felipellrocha commented on Async/Await is finally back in Zig   charlesfonseca.substack.c... · Posted by u/barddoo
dilawar · 4 months ago
Someone has historical insights into why async/await seems to have taken over the world?

I often write Rust and I don't find it very attractive, but so many good projects seem to advertise it as a "killer feature". Diesel.rs doesn't have async, and they claim that perf improvement may not be worth it (https://users.rust-lang.org/t/why-use-diesel-when-its-not-as...).

For a single threaded JS program, async makes a lot of sense. I can't imagine any alternative pattern to get concurrency so cleanly.

felipellrocha · 4 months ago
Being fully multithreaded comes with significant overhead, while browsers essentially proved how much unreasonable performance you can get out of a single cpu using async because of javascript’s async model.

It is hard to describe just how much more can be done on a single thread with just async.

Basically the same as cleaning up after they hired the cheapest dev they can find. Something our little shop has been doing for 4 years now. Can't wait to charge to debug a 100,000 line vibe coded WordPress plugin.

Oh god, there will be money in this for sure, but at what cost?!?

I strongly disagree that "it's a shame" that English does not use diacritics. English is my second language (third maybe, considering that the country of my birth is bilingual), and is my favorite language to read and to write. I tried to learn French for two years and stopped, and all those excessive writing marks were among the reasons.

God bless all those monks who decided to keep English writing clean.

English is your favorite language to read and write? Said no one ever…
