13:40 <rcurtin[m]> jonpsy: yeah, definitely, it is quite intense to build the tests 😃 I will see if I can either figure out how to get ctest to auto-build `mlpack_test` when `BUILD_TESTS` is on, or open an issue about it, or something

13:40 <rcurtin[m]> but first, let's see if the release scripts still work...

13:47 <rcurtin[m]> wow, incredible! mlpack-bot did what it was supposed to do with basically no problems (although the website didn't update quite right, but I'll do that manually now)

13:48 <rcurtin[m]> so finally, after years, mlpack 4 is released 🎉🎉🎉 (I'm really looking forward to the Element chat client spilling confetti all over my screen as soon as I submit this message)

13:48 <jonpsy[m]> 🎊🎊

13:49 <jonpsy[m]> rcurtin[m]: I'm thinking of writing a linkedin post on mlpack 4

13:54 <rcurtin[m]> do it! :) spreading the word about mlpack is great and helpful (and definitely not a skill of mine)

13:56 <jonpsy[m]> I must confess, I'm no Mark Anthony. But I'd definitely like to boast about mlpack any chance given

13:57 <jonpsy[m]> Besides, a lot of people are completely unaware of a competent C++ ML library. Time they wake up

13:57 <jonpsy[m]> s/Anthony/Antony/

15:31 <jonpsy[m]> One question, if mlpack is header only now and since we can precompile headers, all `driver` level code compilation would be super fast?

15:32 <rcurtin[m]> Unfortunately I don't think it is quite that wonderful of a situation :( precompiled headers do some parsing, but the "pain" of compiling mlpack's code mostly has to do with C++ templates, and precompiled headers don't pre-instantiate templates. So maybe there is some improvement, but it might not be as much as you are hoping

15:34 <jonpsy[m]> Hm, isn't `STL` heavily templated too? I get a massive speed bump when I pre-compile `bits/stdc++.h`, how's that possible?

15:37 <rcurtin[m]> hmm, maybe there is some magic to pre-instantiate some common templates? I am not sure... so maybe if you see big gains in the driver code, perhaps I am totally wrong :)

15:38 <rcurtin[m]> I thought PCH was just for the parsing step and some other early steps of the compiler and didn't apply too much to templated code, but, I don't know everything about it

15:47 <jonpsy[m]> Not sure if you're into competitive programming. But its a common practice to pre-compile `#include <bits/stdc++.h>` so that they get all imports + it compiles faster.

15:47 <jonpsy[m]> I'm not aware what exactly `pre compiling header` means and how it boosts it (I'd need your help here). But here's a blog post: https://codeforces.com/blog/entry/79026

17:32 <rcurtin[m]> zoq: is demo.kurg.org offline? maybe it needs a kick or something? I was hoping to get the demo running on the main website again 😃 happy to help out if I can

18:10 <zoq[m]> <rcurtin[m]> "zoq: is demo.kurg.org offline..." <- I’ll look into it later.

18:23 <rcurtin[m]> sounds good, just let me know if I can help. we could probably run the code directly on mlpack.org if you prefer, but it might be a little bit of setup time to transfer it; either way is fine with me
