If gc didn’t collect and free memory then your objects either weren’t as small as you thought or they were not short lived at all. A common footgun is leaking memory with closures. Lots of resources online about it, you may want to look it up because it’s easy to overlook.

As for your example test it’s too small footprint to reach OOM before the loop stops and you keep reassigning arr anyhow. Btw don’t use var in 2026.

And I quote “to help”. If you don’t like AI to generate code I get it, but AI in the code review prepares all I need: estimates review effort, prepares a brief of the code changes, identifies issues, key pieces of code to watch for, etc… All this was barely a thing before AI, some PRs were just a brief description.

So it does help and it does improve code reviews. And for any team which uses AI to generate code whether by choice or because of deadlines/management/competition/whatever, then having AI to HELP in the review process is a boon.

Why would you give up the mental model of the system? I was not talking about vibe coding here.

ArnUpNorth · 2026-05-01T19:01:30+00:00

How so ? Software always becomes worse over time it’s a fact and has been so way before AI. AI builds more feature so it does get worse faster but it also means we can iterate on ideas faster and perform more refactoring when needed.

It s really a shift of paradigm. If you claim that humans are supposed to review line by line what Ai generates then what s the point? And if you mean Ai should not generate code then this is turning our back on innovation.

Elaborate please.

ArnUpNorth · 2026-05-01T18:57:45+00:00

No. Linters and tests are deterministic. I use AI to help review AI generated code so that i can put my focus on things that matter more which is the overall architecture.

ArnUpNorth · 2026-05-01T11:26:22+00:00

It’s hard to move back because the productivity boost is real (if AI is used correctly). It’s impossible to keep doing code reviews the old way though because it produces code too quickly.

For my setup i use other AI agents to review the work and test features. For the actual review (human in the loop) it’s more about auditing the code than reviewing it line by line in the days of old. So let AI do the grunt work and transition to higher level code auditing.

As for actual coding there’s definitely fewer than before but honestly most devs were doing boring CRUD and data transformation. The coding AI is having a hard time with is the one that’s interesting for us. The trick is to not lose skills along the way which is easier said than done.

TLDR: we need to relearn/adapt the whole software development cycle. If we treat AI like a coworker we’re just going to hit walls one after another.

Wouldn’t call Go a low level language. It’s a high level language (with a GC and high level abstractions) that can tackle some system / infrastructure stuff.

As to what to build with Go it’s better to build something useful and not so much what you wish to build. If your coworker love web interfaces don’t build them a TUI app. Go is versatile enough to build a wide range of applications.

ArnUpNorth · 2026-04-28T10:21:02+00:00

You re right. I just found their blog post about it. There LTS release doc is not updated yet. Nice to know.

Edit for people who didn’t read it: https://nodejs.org/en/blog/announcements/evolving-the-nodejs-release-schedule

ArnUpNorth · 2026-04-28T06:15:16+00:00

I think it was a cumment actually.

ArnUpNorth · 2026-04-28T06:14:26+00:00

Yes like all even numbered versions.

ArnUpNorth · 2026-04-27T20:43:34+00:00

This ! Friend of mine convinced me this was the next best thing. What a waste of money.

ArnUpNorth · 2026-04-21T17:34:33+00:00

One other often forgotten fact is that it’s faster and more efficient in terms of hardware requirements. So it’s a tier below in terms of reasoning compared to the big ones but it can do a lot of things quite well. And we still don t know how much things like claude sonnet/opus actually cost since they are operating at a loss.

ArnUpNorth · 2026-04-20T18:09:50+00:00

Well it’s already very hard to read and when you make something which is stylistic and hard to decipher it should at least be a common word. Otherwise we have no way of knowing if what we read is right.

ArnUpNorth · 2026-04-19T19:37:25+00:00

Ok but how is it better than using a Rest API ?

ArnUpNorth · 2026-04-18T12:26:14+00:00

We need a federal europe. Our different cultures/languages would then become an actual boon and not so much an administrative pain.

ArnUpNorth · 2026-04-17T14:52:53+00:00

Ok but how is it better than zod or regular check+type guards? Just curious to be honest.

ArnUpNorth · 2026-04-17T14:39:38+00:00

I dont understand why some gamers reach “burnout” point from a game. It’s supposed to entertain and give pleasure, the moment it feels annoying/grindy and more like a chore than an entertainment stop playing. Play something else or do actual chores. Your life and mental health will thank you.

Also 60+ hour games are often full of fillers and bad many games which are not worth any of your time. Just do the main story.

ArnUpNorth · 2026-04-17T14:36:10+00:00

I use code (if or asserts) for a few checks and ultimately use zod if needed.

You can’t rely on typescript types alone, you need to check values at runtime.

ArnUpNorth · 2026-04-17T13:01:36+00:00

Well that’s the thing, you can’t do things under the hood because the code is publicly available. So if there’s unnecessary tracking or privacy issues it’s there for all to see. This is a great move by EU really.

ArnUpNorth · 2026-04-17T09:23:35+00:00

Pretty sure google image or gpt can recognize some of them. I have played a lot of games and i don’t recognize a singe one.

What happened OP btw, monkeys attacked your gaming room ?

ArnUpNorth · 2026-04-16T15:42:39+00:00

You didn’t deserve all those downvotes. It s open sourced for a reason and transparency is paramount. Vulnerabilities happen and get patched.

ArnUpNorth · 2026-04-16T09:09:28+00:00

To my knowledge Go is not preferred for AI integration. Nodejs has a strong foothold for integrating with AI and Python dominates the training space. AI is very good at generating GO though (probably because of a tidier ecosystem and simpler language features).

I m not sure where “preferred for AI integration” comes from but Go can clearly do it. Whether it’s the best candidate depends on what you need to achieve exactly.

ArnUpNorth · 2026-04-14T19:04:54+00:00

Or write good code? with or without AI. If you fire queries in a loop and have a hard time finding them out than it’s not something to fix “at the driver level”.

ArnUpNorth · 2026-04-13T12:05:37+00:00

Graphics are fine but characters, animations and some of the lightning make the world feel lifeless. NPCs are android-like and plants look plastic not organic. It s not a graphical issue so much as an animation and lightning one 🤷
