Just out of curiosity, I looked at the HN RSS feed and they still use regular escape for titles (and some other things, except description). It means they use 2 versions of escape instead of 1. So why not just use 1?

Yeah, the numbers will eventually overflow if you play long enough, it seems doesn't end.

Maybe. IMHO there is also a microbiome hype train in the recent years. Most of these microbiome studies aren't considering a lot confounding factors. Here is a paper: https://www.cell.com/cell/fulltext/S0092-8

I would still be cautious with such findings. Many autistic people are picky eaters, also some of them have issues with peristalsis. This might affect the microbiome as well. While it's plausible that it might help a subset of people,

IMHO, for servers IO (FS/DB, network, etc) is usually a greater bottleneck. Microoptimizations make sense only for CPU bound problems.

Yes, but doesn't run locally.

In ideal world, but it's too late. The codebase is old. It's very difficult to backport/reimplement/integrate features (tons of APIs, kernel features, etc) that new software relies on. Also, because of compatibility you

IMHO the last truly brilliant and consistent version was 7. Ideally MS should do such improvements on Windows 7. Sadly, Windows developers also have to deal with the mess created during Windows 8/8.1/10/11.

For me it's slightly misleading because it's almost like saying "I wrote a faster quicksort implementation, so it beats quicksort!". In this case the binary search fundamental idea of "divide and conquer" is st

I guess it matters if you have to do lookup in a tight loop. If you do this occasionally, I think it's not worth it, especially for complex objects with custom comparators. The algorithm is still O(log(n)) just a more advanced "di

The title is slightly misleading, I mean yes, naive binary search might have larger constant but the algorithm is still O(log(n)). This is still some "divide and conquer" style algorithm just with bunch of CPU specific optimizatio

How efficient is AI at reducing RAM consuption?

by senfiaj 6mo ago
I think there are some standard header bytes, so the number of combinations of the interesting parts might be much smaller. Also I said less than 7 bytes, so it's actually 281474976710656 . If header bytes reduce 1 or 2 bytes, it will

I wonder if this might motivate to write more memory efficient software. I mean we have so much memory, but even some trivial programs eat hundreds of megabytes of ram.

I guess anything that is less than 7 bytes can be brute forced.

Probably because JS has larger runtime, in JS you don't have to write about most of the low level code. So it's easier to squeeze code in JS than in ASM or machine code.

Again, there is no simple answer. It depends on situations and resources. Some systems might rely on multiple services. If those services are independent, in such system this might cause more frequent failures which might still result in se
