Why do you loop over haystack multiple times though? If you iterate over long string once and write fixed loop with vowels checks in way that will be friendly to autovectorize optimization it might be faster and more idiomatic C or C++.

disclaimer - I work in gamedev. It certainly looks like the only thing that has any attention to it is Copilot/AI. tbh, I don't think community here actually cares about games or technical details to go through lists of topics :)

While novel it also very far removed from hardware. In sense that aggregating what actually going on with work submitted from multiple queues is hard. Even gathering timing events for start stop of each can be confusing and not adequate whe

>Personally, I find the idea that a compiler might be able to reach outside itself completely terrifying (Access the network or a database? Are you nuts?). In gamedev code is small part of the end product. "Data-driven" is the

I would say that Highway [1] comes close. Can't say anything about ISPC because in gamedev work it never even came into consideration for multiple platforms. 1. https://google.github.io/highway/en/master/

if you plan to look at pointer provenance please check recent HN discussions like this one ( https://news.ycombinator.com/item?id=42878450 ) and transitively links to source papers for C. TLDR (imho) C has failed to define

Judging from 'comparing pointers of different provenance' can produce 'any result' ( here https://c3-lang.org/language-rules/undefined-behaviour/#list... ) everyone has to deal with it. More lo

A low effort question on what's C3 take on pointer provenance. Does C3 have any own take on it? Are you with C or with your implementation detail (LLVM) ? Also if you have 'tourist guide' for gamedev people please share links

What do you think about 'par_iter' having to wait for work imbalance to return execution back? With 'when_all' like primitive one can continue execution on any thread without losing one for waiting. ps as someone who do

Fun fact that we have burned those bridges years ago. Every time big codebase updates it's main optimizing toolchain (compiler/linker) ... there is nothing deterministic and predictable. There is only what has been re-tested and w

Good luck with metaprogramming. It looks cool. No worries, I got your message about target audience first time. It's just that language development for me is where I did some things. Langdev is an open ended problem. I wish I could exp

I guess I need to illustrate my points a bit because I never needed to poke kernels and my concerns are mostly from large games. I am trying to imagine writing large games in your language so please bear with me for a moment. >Modules No

I think you don't need any rants but here it goes anyway. Ditching headers does not solve anything at least if your language targets include performance or my beloved example Gamedev =) . You will have to consume headers until operatin

Thanks! Updated results are interesting.

Non video version is there [0]. My take on it is that there are no 'language comparisons' there. Difference is between older and newer algorithms and benchmark favorite is written in C. Its cool that new algorithms are implemented

Do you happen to have a link for benchmark ? i would like to learn what i miss happening in rust. Last time i read about sort implementations here on HN [0] rust panic safety had some measurable costs: 0. https://news.ycombina

As much as I (as engine/performance guy) would like to see strings gone we have not eliminated them. Passing allocators hit a brick wall because most of the code is threaded tasks and to make something that will go into another async A

Thx for linked thread. It was an interesting read to me. I have got a feeling that the division comes from two different system programming folks. Hard realtime folks see unbounded time and uh-oh its fatal. On other side soft realtime folks

Many orgs want to save costs while using open software. In a world after xz incident they are now in very difficult place. It is all about whom do one trusts. As someone who works in such costs aware business as gamedev I think Rust has uni

In gamedev a lot of people read those docs but not a lot of them shipped anything using it. The reason is that file paths are not everything that has A/W versions. There is user input, window message handling ... The API is a maze. I r

Well the pool code fails to use char* type to write inside block of memory. If you look at 'pool_free' code you can see that it receives used block from user as 'ptr' then casts it to 'Chunk pointer' and writes

A code tends to be reused. When it happens jira is not likely to travel alongside the code. All 'older' jira tickets are useless broken links. All you have in practice is jira name. It usually happen with 'internal documentat

I appreciate your perspective and it is correct. I should have phrased it differently. Imho: I worked with code that has long history for my entire career. If the goal is to look at some objective quality of solution then I do not believe i

It is normal for coding to seek feedback from others to your solution. Even if it is automated. Looking at 'competing' solutions after you spent time on yours can teach how others think. Improving code after you learned new facts
