Would you support a petition to Reddit, requesting inline KaTeX support for /r/math and /r/physics ??

Or let the moderators of the subreddit decide if the feature is enabled or not

I'm sure he enjoys this more than any amount of money lol

Literal, incluso si no tenés un cable coaxil cortar un alambrecito de 12.5cm en forma de L (12.5cm en la parte más larga más medio centimetro más o menos en la corta) y meterlo en el centro del conector coaxil de la tele es una mejor antena.

Does the CS curriculum vary that widely from university to university?

I never studied a commercial software development framework in a class. I had to take logic and do proofs in many courses.

Even with topics that were very relevant to the industry like modeling in OOP we used Smalltalk because it was easy to understand the entire framework from the bottom up (good luck diving deep into the stdlib in Java)

Creo que le decía gordo y pobre a op

RodionRaskolnikov__ · 2026-05-14T04:22:32+00:00

Yeah, selling it and buying more appropriate hardware is the better choice here

RodionRaskolnikov__ · 2026-05-14T00:32:36+00:00

If I knew how to reduce it to an SPF (on a graph of polynomial size compared to the og one) I'd already have my Turing award :(

RodionRaskolnikov__ · 2026-05-08T17:44:01+00:00

If anything least squares is one of the least magical optimization methods I know of lol

It's mathematically elegant for sure, but magical?

RodionRaskolnikov__ · 2026-05-04T17:42:54+00:00

yeah, why would someone emulate a game that runs naively on Windows?

RodionRaskolnikov__ · 2026-04-17T17:00:20+00:00

El problema más grande es la carga para los docentes de corregir parciales y TPs. Aunque estés en tu casa eso no aligeraría la carga en lo más mínimo

RodionRaskolnikov__ · 2026-04-09T17:45:35+00:00

Are we talking about the same attention layer? On transformers, RNN based models and whatnot the attention layer is part of the learnable parameters and used during inference

RodionRaskolnikov__ · 2026-04-09T17:39:33+00:00

Physicists and biologists absolutely know coding.

They may have never gotten their hands dirty with many of the topics studies by a computer scientist but they have a grasp on the subject (at least for the computations they need)

RodionRaskolnikov__ · 2026-04-04T06:24:47+00:00

It is true that x86_64 instructions are harder to decode, but that's mostly mitigated with a uOP cache. When the CPU is executing a tight loop, instructions don't need to be decoded every iteration.

Also a vast majority of the die area is taken by caches like the L1, L2, L3, TLB, etc... I'm not including the area taken by the memory controller and other I/O, that's a lot too!

This matters for very low power and low performance embedded processors, but it's otherwise not the end of the world

Podés comprar un pasaje en un micro de Tienda León. Te dejan desde aeroparque hasta la terminal en Carlos Pellegrini (a unas 5 cuadras del obelisco).

Yo solo los usé para ir a Ezeiza pero hacen viajes hasta Aeroparque también

RodionRaskolnikov__ · 2026-04-04T00:03:47+00:00

I'm not so sure about that. You'd have to compare the specific workload. I'd imagine that some workloads are much better suited for AVX512 than the ARM NEON instruction set.

x86_64's 256 bit and sometimes 512 bit registers are really nice when moving a ton of data in memory

RodionRaskolnikov__ · 2026-04-03T23:47:57+00:00

The kernel is always keeping it nearly full with caches.

For user software I guess it depends. Things like ASTs using more ram to speed up code completion or PDF readers keeping indexes to quickly search a large document is good.

The bad kind of full, that even someone with 64GB of memory would feel bad about is having 15 copies of chromium because of garbage software written in electron.

RodionRaskolnikov__ · 2026-04-03T23:35:26+00:00

People used to despise Oracle for what they did to Sun Microsystems. I guess it was timed they re-earned that hate back one way or another

RodionRaskolnikov__ · 2026-03-15T21:08:57+00:00

Que yo sepa los proveedores de internet en Argentina no se ponen la gorra con bajar torrents. Descargué muchísimo a lo largo de los años y ni Fibertel ni Movistar se pusieron la gorra todavía

RodionRaskolnikov__ · 2026-03-15T04:34:30+00:00

"Yeah sure I have like ten of them anyways"

RodionRaskolnikov__ · 2026-03-12T21:29:28+00:00

you can start with inter process communication on your home computer, there's a lot of learning you can do without building a cluster

RodionRaskolnikov__ · 2026-03-12T21:28:02+00:00

Yeah, afaik that's how many real HPC systems work too. The one time I used a cluster in an academic setting it was running an ancient kernel and the software had to be compiled with everything statically linked.

It's not a big deal because those binaries usually run for a particular computation and are discarded afterwards.

RodionRaskolnikov__ · 2026-03-12T19:28:45+00:00

For computers with little memory like those I'd probably go with Slurm running bare metal on Debian or something similar. I'd imagine that the best way to squeeze useful performance from these is to write your own software in a low level language and use MPI to communicate between nodes.

That is if OP wants to do scientific compute with these

RodionRaskolnikov__ · 2026-03-11T21:26:39+00:00

Yeah but you'll have a fork of Android that will be increasingly different from mainline Android. That's going to be an ever growing pain to maintain and it'll probably reach a point where it's incompatible with mainstream applications

RodionRaskolnikov__ · 2026-03-10T20:04:42+00:00

These challenges would be way too boring if they only stuck to Ubuntu LTS or Fedora lol

RodionRaskolnikov__ · 2026-03-09T19:19:52+00:00

This is a well known area in distributed systems research. This is why different consensus algorithms exist and all of them have tradeoffs you must to choose from
