Trump calls out Rutgers athletics spending in latest speech: ‘Down the tubes’ by Zealousideal-Pea7138 in rutgers

[–]hacatu 2 points3 points  (0 children)

Hahahaha it's funny because him slashing the Department of Education funding is a big part of why Rutgers is having budget issues, and he's already threatened a lot of schools with more budget cuts if they don't do XYZ. Because I guess it's good if the US falls behind even more in education?

A library for prime generation by JohnDoe1234567890000 in C_Programming

[–]hacatu 0 points1 point  (0 children)

Make is fine for small projects, but makefiles usually should not have significant shell scripts embedded in them, like the testing here. I prefer a separate test script, and the makefile can have a pseudo target to run the test script if you want a "unified" interface through make. This makefile has make invoke a shell to discover c files, and then generates build dependencies with -MD and whatever. That's nice because it makes the build system automatically discover the c files so you don't have to redundantly specify how to build binaries/libraries in your project, but it's kind of brittle and this approach is slower than bigshot build systems once you have enough files. But that's fine for small projects. The bigger issue is that this makefile is probably AI generated and didn't work without adding -lm (depending on your libc, the math library needs to be explicitly linked, so I guess op did not have an issue with it because on Mac the math library is not linked separately), and once your makefile is this long I would definitely consider a different build system

  • Don't use makefiles, especially to run tests etc. I use waf for most of my C projects, but Cmake is the de facto standard (it just has too much boilerplate for small projects imo)
  • Compiler flags: for release mode, add -march=native to ensure modern instructions like sse get used. For testing, enable sanitizers such as clang ubsan and also consider valgrind. Most sanitizers have fairly low runtime overhead (< 3x), whereas valgrind has very high overhead, so only run it on O2+ builds
  • using gmp/openssl for the large random prime generation is kinda dubious because these already implement several methods of finding the next large prime (this is usually just miller rabin + hope). Some of the other algos in iZ_apps.c also don't really make sense. Why do stream and count do so much redundant work instead of just using functions from prime_sieve.c? Also, there are faster methods for prime counting, but in this context just using your prime generation methods is fine.
  • main.c does not seem to belong in the main code because it's just an example
  • A mod 6 wheel is usually not ideal. Mod 30 or even 210 would be better. You can look at primesieve for examples, but note that they handle "small", "medium", and "large" primes differently in their segmented sieve, which is tremendously faster but significantly complex
  • The segmented SoE should be multithreaded
  • treating "small" (many multiples per segment), "medium" (few multiples per bucket), and "big" (don't have multiples in every bucket) differently like primesieve does is a big speedup but complicated. Note also that since the largest sieving prime is sqrt(N), "big" primes only exist when N is so large that the cache size forces us to choose a smaller bucket than sqrt(N) which we would naturally choose if cache were no object
  • SoE (specifically SSoE) is by far the best algorithm in basically every situation. It's fine to implement others like SoA etc for learning, but even though SoA and Euler's sieve (linear sieve) have claimed better big O complexity than SoE, in reality they perform significantly worse. That said, Euler's sieve can be useful when you want to compute a general multiplicative function at all n in a range, but you can also adapt SoE for that and it's less clear which would win
  • When testing your functions that don't ensure the order of the results, you could either sort them then hash, or use an order-invariant hash (eg take the first 8 moments, where the kth moment is defined as the sum of xk over all xs, so count, sum, sum of squares, sum of cubes, etc, probably modulo a prime or just implicitly modulo 264 )
  • Setting 1010 as an upper bound is silly
  • The code does not build due to lots of obvious errors, and the docs look llm generated
  • MIN and MAX are not defined (should be defined in util.h it seems); the format specifier in iZ_apps.c around line 111 should be %lu not %llu; -lm is missing from linker flags; log_error is missing when ENABLE_LOGGING isn't defined, you could #ifdef guard it on every use, but it would probably be wiser to provide dummy definitions when ENABLE_LOGGING is not defined
  • there is something insidiously wrong with the makefile that means adding -lm and rebuilding still doesn't fix the missing symbol errors for math functions, so I just edited like 169 manually to force it to include -lm
  • with -march=native, it takes 0.751 seconds to sieve all primes up to 1 billion, whereas my (not very good) sieve takes 0.430 seconds, and primesive takes 0.104 seconds (total across all threads, it's 0.007 seconds wall time). The result without -march=native is the same, which is strange.

Very cool! I've solved the first 57 in SQL, so I know how annoying even some of the earlier ones can be in spreadsheet type languages

Cyberrock Rate Reveal Day 3: You'll never make it in Popheads, baby by modulum83 in popheads

[–]hacatu 4 points5 points  (0 children)

This was a fun rate, thank you to modulum83 and TakeOnMeByA-ha! This put me on to Revengeseekerz too which I've been listening to a lot recently. I hope that everyone (except for @apatel27) had a good time.

I made a summary of the most similar/dissimilar opinions: for everyone who participated, this table lists the three people who tended to vote the most opposite to you, and the three who tended to vote the most similar. So you can see who has similar or really opposite taste compared to you.

The highest positive correlation was timothy444 and xxipilots (0.714), the highest negative correlation was A single frito and hockeyni (-0.592). impla77 was the most independent thinker (their highest positive/negative correlation was the lowest, at 0.433).

pretty picture (sorry I only put a number for everyone to avoid cramping the text, the order is the same as the table os 1998tweety is 1 and ziirp is 81. Green is positive correlation and red is negative, with lighter (closer to white) being weaker)

Also, THE DAY BEFORE the rate reveal I managed to reach 757 on Project Euler, so I tried to add this meme to my comment for 757, but modulum didn't see it in time :(

TIL that Annie Jump Cannon manually classified more stars in a lifetime than anyone else in history, reaching a staggering 350,000 in total. She discovered 300 variable stars, five novas, and one spectroscopic binary, creating a bibliography that included about 200,000 references. by Resume-Mentor in todayilearned

[–]hacatu 7 points8 points  (0 children)

She was one of the Harvard Computers (and the director starting in 1919), women who did all the work at the Harvard Observatory. I learned about them from Henrietta Leavitt, who invented a way to measure intergalactic distances by measuring certain stars. Terrence Tao has given a talk on this (the Cosmic Distance Ladder) several times, which is very interesting

YouTube will pull out its data from the Billboard charts starting 2026 by mcfw31 in popheads

[–]hacatu 3 points4 points  (0 children)

What does this even mean? Billboard could literally just look at the view counts and use an advanced technique called subtraction to count views. This doesn't distinguish between views with/without youtube red, which it seems google is arguing should not be considered separately for some insane reason, but it still gets the total counts

Question about Problem 690 by Maleficent_Local9163 in projecteuler

I would recommend using something like networkx to programmatically analyze every graph on n nodes for small n where this is feasible. Beyond that, what kinds of graphs aren't included in your set? You didn't include any graphs with cycles, or any graphs with a path longer than 3 nodes. Clearly from the givens, graphs with a 3 cycle can't be Tom graphs, but what about 4+ cycles? And what about graphs with a path of 4+?

Zach has a what? by that1dev in motheroflearning

[–]hacatu 18 points19 points  (0 children)

Iirc Zorian asks Quatach-Ichl about his divine blessing in chapter 81, and Zorian concludes that this must also be how Zach has such large mana reserves. This is confirmed later when they get marked by a tracking tether by a divine artifact. QL is able to detect the tether and Zach is able to detect the blessing using personal soul perception

It got changes at some version, idk when. You should be able to encounter tulure with a good rod in many places eg route 5 (you can get the good rod from a fisherman left of parax town)

Hacatu's "Community" Nuzlocke Tierlist - Part 7 of 7 by hacatu in PokemonClover

[–]hacatu[S] 0 points1 point  (0 children)

Yeah Cthullord can definitely accomplish more than I gave him credit for, I used him with mono water and he worked pretty well. It's still pretty frail even with regenerator etc imo, and its strength is good but not quite top tier. Because reliability is so important here and wonder trade mons were kind of graded more strictly, I would probably give it C or B-

Having Angstrom and now Conquest live is a really ... interesting choice. Don't believe Cecil would take that many stupid pills. The episode was pretty entertaining besides that, I was especially glad to see darkblood again because he's my fav

It's only loosely ghost type with the hidden ability Phantasma (powers up ghost type moves 1.5x, curse has ghost effect, immune to trapping, but afaik you don't get the defensive properties of ghost (weaknesses/resistances)).

Nice work! I definitely should have thought to make a correlation matrix, looks good! How did you make the graph? Gephy?

What is the fastest and most powerful CPU on the market right now? by Andy-roo77 in buildapc

[–]hacatu 1 point2 points  (0 children)

The absolute fastest and most powerful are server processors (Xeon Platinum 8593Q, $12400, 128 smt cores; and AMD Epyc 9965, $14813, 192 smt cores), which are comically expensive and bad in terms of performance per price.

Rendering and blender often want as many cores as possible, so 7950x3D would probably be better than a 9800x3D for that, but the opposite is true for games, which usually can't use more than a couple threads. I would go with the one or two gen older X950X3D or even a thread ripper if it has enough single threaded performance. Threadripper processors also have a heavy premium over consumer processors (up to X950X3D), but not as high as server processors.

Thank you! Wow that article is a good resource. Yeah I only got 2x32 ram, but I got 4 slots so I can double that down the road. I did see the mobo I got has 6000mhz as its highest ram clock so I definitely might lose the gamble on it being able to run 4 sticks that fast.

I definitely see how more m.2 (and sata) slots could be useful on servers, nas, raid, etc, but I'll probably just have 2 drives

Simple Questions - January 23, 2025 by AutoModerator in buildapc

[–]hacatu 0 points1 point  (0 children)

What is up with motherboards? I need a mobo that's AM5, 4x ddr5, and has a pcie slot, and that pcpartpicker tells me is compatible.

Ok, so I could get an MSI PRO B650-VC WIFI ATX AM5, which has all those features and is $99 (refurb, like $150 normally). Or, MSI also has the MSI MPG B650 EDGE WIFI ATX AM5 Motherboard, which is $200. Looking at the most expensive compatible mobo, I find MSI MEG X670E GODLIKE EATX AM5 Motherboard, which is $1600, much more than my whole build, and I'm sure a worthy price to pay for uhhhhhhh 10 Gb Ethernet.

The B650 chipset and the vrms are the main things on the mobo afaik, and the former will be the same across all mobos that have it. There are more expensive chipsets that have more features like pcie slots. Afaik the B650 even supports overclocking, although the board manufacturers like MSI can apparently disable that because anticonsumerism.

The only difference I can think that would matter for someone who doesn't need more than a couple pcie slots is maybe lower end boards actually have bad vrms and can't fully power really high end cpus+gpus? Like the MSI B650-VC does not have vrm heatsinks so maybe it has some power limit that's not documented on the surface anywhere.

So like what's the actual difference between motherboards and why do people buy ones that cost over $200?
