Please no AI slop. I don't want another app that spams my server megabytes per second because my proxy failed and the programmer didn't acknowledge the server can ever go down (talking about Immich - their retry mechanism used to be a while true loop with no back off nor retry limit) or the app resets the upload whenever I bring the app to foreground (also talking about Immich).

Unfortunately doesn't support Vulkan decoding/encoding (ffmpeg 8 does).

I wonder if the code was written by AI?

I don't see anything business related in that statement.

What's this new level of gaslighting? "It was not because of me, but because of the business situation I was in". Wait... wasn't he in that "business situation" because of actions HE took?

This is good. However, it still sends info about the players ~200ms ahead which still makes you lose.

> memory monitoring would be part of the application monitoring stack

You don't need it if you have everything allocated upfront. TigerBeetle does this, everybody else can.

Using something like Rust is already a huge win when compared to shipping a browser or running Node.js.

> Your argument falls flat when a page file can be multi-GB and automatically grow

This doesn't solve the original issue and only masks the underlying problem.

> this leads to application crashes instead

Same happens if the page file is full. In that case, why don't those programs use disk directly instead?

No such problem would've ever occured if programs hadn't allocated more than they actually use.

> Does this result in programs more frequently erroring/crashing because they can't allocate?

I run Firefox, VSCodium with LSP, Discord, Signal and there's still space left for a game like CS2. I'm not a heavy user by any means.

> I'm not sure they would do much better than crash

I have yet to see a program that silently handles allocation failures and doesn't crash. These days everything is coded to crash if no memory :(

> About once a year a real runaway process (usually a throwaway program I'm working on) gets OOM-killed

In my case it killed system critical processes with no way to recover. With disabled overcommit, it freezes for a while (usually for a minute or two), I close some random program of my choosing and then see in Resource Monitor what's eating my ram.

I have disabled overcommit both on Windows and on Linux. I hate having random programs being killed.

Unfortunately, many programs commit 2x memory than they actually use. Often I see ~32GB committed and ~16GB resident.

The wording is so ambiguous, they should've determined what's the threat first. Or else anybody could point at anybody and say "active threat".

Most likely they still would've been kicked, but without being detained.

Ah yes. Let me detain you for 8 hours for doing what you're legally allowed to do. Sorry for my mistake, it's all paid by the taxpayers anyway.

It's always this one exact excuse. They were simply "following orders". The police don't have their own brains capable of thinking.

I never claimed so. Please stop stating I said something when I didn't.

> as a general purpose hash table

That's what I claimed. The question IS about hash tables. If you want a hash table of any content, it's impossible to get faster. Unless you check all possible keys at once - only this will get you faster.

No. Fundamentally it's not possible to be faster.

> isn't available in all cases

Which ones? Websites that ship no JavaScript? All browsers support this.

> can in some cases completely break sessions

Or you can just remove local storage from window and have it just for yourself, which seems what Discord is doing as well.

Attackers cannot use local storage because there is no local storage on the window object.

> A separate attack vector for the same problem

It's not exactly the same problem. The example you mentioned is a footgun because you don't vendor your dependencies. Deliberately giving someone else access to your website is an issue in itself.
