I thought I read somewhere that Zen 2 will downclock based on heat, rather than simple instruction set heuristics. I can't find a source though, so take that as hearsay for now. Intel CPUs do downclock for both avx and avx-512. Many mo

These were different teams of students taking a class. Variance in student effort/quality is generally high. There were two Rust teams. One had 3x the code and passed less tests than the other. This is our only reference for how much n

The 1950X cost $1000 2 years ago, and it looks like you can pick them up for $500 now. Both are 16 cores with two chiplets. 1950X advantages: - 4 memory channels vs 2 - 64 PCIe lanes vs 16-4-4 3950X advantages: - 64MB of L3 cac

Aditionaly, in statistics Greek letters denote parameters, while the modern Latin alphabet we all use today is for variables. The data `x` has a normal(mu, Sigma) distribution, for example. These sorts of conventions enhance readability by

I use gnome-terminal instead of xterm in i3. gnome-terminal supports tabs (control+shift+t), so I can easily choose between a new tab versus a new window.

I regularly get migraines, where "bright" lights are searingly painful to look at. When the symptoms aren't too bad, dark themes on a text editor are okay, but light themes are not. Migraines aren't an uncommon problem.

I'd like to say I'm a huge fan of Julia, and don't have much experience with metaprogramming in other languages. I'm sure I do more of this than necessary, but much of my code ends up being "generated functions&quot

When I dabbled in gfortran, a feature I liked was that while no bounds-checking is the default, run time bounds-checks can be enabled with "-fcheck=bounds" or "-fcheck=all", which can be handy while developing/testi

Yes, I was quite happy with reticulate, when I tried it. I like the workflow of working on code in a script, with hotkeys to run code blocks in the REPL and jump to the next block. If I am actively working on code, I'm unlikely to want

Multiple dispatch and meta programming are both wonderful, irrespective of speed benefits. For example, compare linear algebra syntax in Julia with those in R and Python. Plus, the flexibility of multiple dispatch applying equally well to a

Julia's `ccall` is great in terms of overhead[0], so calling Rust shared libraries is not a problem. On the Rust side, it took me a while to figure out passing in pointers, and then constructing slices via from_raw_parts[_mut], so that

Yes. This is easy to see in Julia, by comparing native arrays with StaticArrays.jl. Native arrays operations are linked to OpenBLAS, while many StaticArray operations are unrolled (will have to get to a computer to see if that includes 5x5

Isn't it just that it is hard to prove there's no aliasing in C, which can make it harder to vectorize? If so, "restrict" should handle that in most cases.
