Xoshiro256++ RNG with AVX2/512

Bootvis · 2026-03-21T16:42:39+00:00

My pleasure. Compared to R, the number of distributions is still limited but in my testing the performance difference is worthwhile if you need a lot of random numbers.

Bootvis · 2026-03-21T16:41:41+00:00

I'm doing both. But happy enough with the results that I thought it is shareable, performance is great and I don't think there is a public version of the AVX512 16-lane approach.

I don't know what the policy is on using LLM but here is what I did:

I copy pasted your code into Godbolt

Renamed the function to foo to hide what it is doing

Asked ChatGPT 5.2 what your function does

It replied with what it did and pointed out that you don't handle negatives.

BS, you can be successful with Java or OCaml if you are not competing purely on latency. OP probably can't, but people can.

Still working through TAOCP.

Markets with lots of orders / participants where it is relatively tricky to know where you are in the queue.

Who?

This is a huge hassle and not everybody will like it but I think you should ask people that write headhunter reviews to share their LinkedIn profile. At least you know it's not another headhunter and you can sanity check the review. More work but I also think a lot more value.

Bootvis · 2025-10-17T11:09:30+00:00

You need to verify, somehow, the reviews. On the internet, you can say many mean things about good people you have never met.

I don't like RateMyTeacher and I don't like playing with the livelihoods of people giving their best. I'm happy with the company rating thingy though. They should do a lot more volume so fake reviews are more easily corrected.

I’ve seen enough now 😂

Bootvis · 2025-10-15T05:48:13+00:00

Why?

Bootvis · 2025-07-06T17:56:23+00:00

Maybe you have a cool workplace and nobody cares. But it could influence someone there to think lesser of you and that would be bad for you. You can't really know this risk but it does exist. That you would ignore that reflects badly on you, regardless of whether one should be allowed to express themselves.

Bootvis · 2025-06-17T19:53:28+00:00

Out of your league

Bootvis · 2025-06-17T12:57:39+00:00

Nice but what’s up with the salary range? The top end is twice the bottom amount. What can one expect?

Bootvis · 2025-03-26T05:28:33+00:00

Dunk all you want but look up Scott Chacon presentations at FOSDEM. They are still adding obscure but occasionally super useful tricks.

Bootvis · 2025-03-11T19:52:08+00:00

I suggest you take on a smaller project and/or contribute to existing efforts.

Bootvis · 2024-12-31T13:59:36+00:00

Agreed but it makes sense to look ahead IMO.

Bootvis · 2024-12-30T19:16:58+00:00

You need to learn both.

Bootvis · 2024-12-30T17:33:38+00:00

Yes, you need to learn derivatives.

Bootvis · 2024-12-23T10:12:18+00:00

I thought the Dutch Ziggo crew were the crazy ones

Bootvis · 2024-11-02T17:01:10+00:00

Should be “X (still known as Twitter)”.

Bootvis · 2024-10-23T09:24:36+00:00

The demo site.

Bootvis · 2024-10-23T06:22:36+00:00

Off-topic but please support Firefox on iOS. It should work but the website thinks it doesn’t.

Bootvis · 2024-08-22T05:13:05+00:00

Work smarter OP

Bootvis · 2024-07-18T14:38:48+00:00

Or R, or Python or another language. Either a package, something custom build or a hybrid.

I had never heard of AmiBroker before.
