AMD Krackan Point Sub-$500 Laptop Linux Performance Improves By ~8% In Just Six Months
As an end-of-year tradition at Phoronix for running a lot of year-over-year comparison performance benchmarks and other long-term performance evaluations, it’s typically done on the higher-end hardware. That’s done for a matter of time savings with maximum performance when running often 100~200+ benchmarks per article, the highest-end hardware typically being the most interesting in terms of features and capabilities, and more … ⌘ Read more

I just had a closer look at https://git.mills.io/prologic/mu and it motivated me to do some compiler building myself again. Hopefully, I find some time in the next free days. I’m bad at it, but it’s always great fun.

@prologic@twtxt.net I’ve been awake at that time, didn’t notice anything. 🤔 Where was that BGP analyzer again … 😅 There’s a tool that keeps track of these things, right? I forgot what it was.

@prologic@twtxt.net @movq@www.uninformativ.de A crocodile had bitten the big submarine internet cable that connects Australia to Europe. The investigations revealed that some construction work last week accidentally tore up the protective layer around it. That went unnoticed, unfortunately, so marine life had an easy job today. For just 40 minutes, they were quite fast in repairing the damage if you ask me! These communication cables are fricking large.

Just kidding, I completely made that up. :-D I didn’t notice any outage either. But I didn’t try to connect to Down Under at the time span in question.

Is Xbox Betting on Cross-Platform Gaming?

@movq@www.uninformativ.de Very nice! I often wish other languages had something similar. Sometimes, I use lambdas, but that also looks ugly and feels a bit like a misuse. Other times, just the normal blocks are enough, but it’s not the same. Especially with the mutability aspects as the article explains. Typically, I just put it in a function or ignore it if it’s just a few lines.

@movq@www.uninformativ.de Ah, cool! :-) Yeah, it’s very wild what is happening under the hood all the time.

Day 9 also required some optimizations, if you aren’t careful, you end up with really inefficient algorithms with time/memory complexity beyond what a typical machine has 🤣

Day 7 was pretty tough, I initially ended up implementing an exponential in both time and memory solution that I killed because it was eating all the resources on my Mac Studio, and this poor little machine only has 32GB of memory (I stopped it at 118GB of memory, swapping badly!), This is what I ended up doing before/after:

• Before: Time O(2^k · L), memory O(2^k), where k is the number of splitters along a reachable path and L is path length. Exponential in k.
  
• After: Time O(R·C) (or O(R·C + s) with s split events), memory O©, where R = rows, C = columns. Polynomial/linear in grid size.

I’m seeing crashes in the 3D subsystem. (Gallium? Glamor? Whatever other Mesa thing they have? No idea.) In the logs I find this:

malloc(): unaligned tcache chunk detected

And that’s why I still care about Rust and want to learn more about it, even though it’s giving me so much headache and I’ve given up so many times. Because Rust currently seems to be the only popular systems programming language that tries to eliminate these error classes.

And of course “the Rust experiment” in the Linux kernel has recently been concluded as “successful”, so that alone is reason enough for me:
