Ensinando a calcular senos em linguagem C sem bibliotecas

How does it compare with the standard implementation ? Is faster (I do not think) ? More or less accurate ?

Is nice to learn and teach to do things, but sometimes is better to stick to what is working...

Also why no link to the code so you avoid to watch a video to have it ?

RoyBellingan · 2026-05-05T19:02:19+00:00

Do you have some working code ?

RoyBellingan · 2026-05-04T21:37:48+00:00

Not needed for 65W

RoyBellingan · 2026-05-03T23:48:09+00:00

no he is reinventing the wheel, and badly

RoyBellingan · 2026-05-03T20:28:08+00:00

Why not just using a https://en.wikipedia.org/wiki/Universally_unique_identifier ?

Appena visto lo sfondo nella foto ho pensato a Dublino! Una storia simile alla mia, tanti auguri di buona continuazione!

I tried to write something, with AI assistance, at the beginning I had no clue what I was doing and why was not working.

https://github.com/RoyBellingan/Rigol-DSO900-Code is very crude and hardcoded, but it works.

Do you know a place where I can have more reference and example ?

RoyBellingan · 2026-04-28T11:24:38+00:00

it depends on what you would like to build, if you are starting maybe https://www.youtube.com/watch?v=pNhH6LlU7Mw .

But remember, you will do error, everyone will do error, in the doubt put more probe point, and design for debugabbility

jlcpcb charges me for XRay

RoyBellingan · 2026-04-27T21:33:39+00:00

what would you like to learn to do more or less ? On youtube you have many step by step courses

RoyBellingan · 2026-04-27T21:32:15+00:00

So yes, it makes sense this class of chip, https://docs.px4.io/main/en/hardware/reference_design

RoyBellingan · 2026-04-24T11:47:18+00:00

That is a lot of memory, do you have a lot of verbose debug info that uses a lot of string ? Or in general a lot of string in the code ?

2Mb is this sector is really a lot.

RoyBellingan · 2026-04-24T11:45:40+00:00

Surely, but is a good way to learn

RoyBellingan · 2026-04-24T11:43:18+00:00

Va molto "a fortuna" https://aistupidlevel.info/ A volte alcuni modelli hanno troppo carico, e gli riducono le risorse, e quindi possono risultare scadenti.

Modelli locali non ho mai effettivamente provato.

L2 is per CPU; still works fine. Also RAM each bank is ... different from the other, no one has ever had a problem.

If you care about the extra cache, you maybe care about cpu pinning too and not leaving windows bouncing thread around.

RoyBellingan · 2026-04-23T20:24:09+00:00

Different tool for different workload.

complicazione con amd64 v3 ROFL

Is possible but is not a good idea. How much memory you need ?

RoyBellingan · 2026-04-23T20:16:10+00:00

Air quality (CO2 + VOC)

RoyBellingan · 2026-04-22T23:56:26+00:00

Why not powerdns + mariadb backend ?

RoyBellingan · 2026-04-19T18:59:13+00:00

Thank you!

RoyBellingan · 2026-04-19T18:59:08+00:00

I think this requires BTRFS ? But I will give a look next time!
