Python Performance: Why 'if not list' is 2x Faster Than Using len() in c/[email protected]
[–] [email protected] 1 points 1 day ago* (last edited 1 day ago)
  1. Performance is often more tied to the code than to the interpreter - an O(n³) algorithm in blazing fast C won't necessarily perform any better than an O(nlogn) algorithm in Python.

An O(n³) algorithm in Python won't necessarily perform any better than an O(nlogn) algorithm in C. Ever heard of galactic algorithms?

The overhead my classmates had dealing with poorly optimised code that caused constant cache misses was far greater than the interpreter overhead in my code (though at the time I don't think I could have explained why their code was so slow compared to mine).

Did they write naive linear algebra operators?

There are decades of articles on c++ optimizations, that say "use empty() instead of size()", which is same as here.

Derp. You are right.

Ubisoft's stocks aren't ubisoft's assets. It is opinion on how much they worth, not how much they have.

Concerning CrowdStrike (infosec.exchange)
 

We are now at t+26h. Please compare how much we knew about the xz-attack after less than a day with what we know about the chain of events of giant outage yesterday.

If something similar had been caused by an OSS component, we would see congress discussing a ban on open software in critical infrastructure already.

Reddit mods ban for "not punctuating correcttly" (mastodon.social)
 

Some of the new Reddit mods are so toxic. Instead of apologizing for the bot being too harsh and reinstating my submission, they just banned me because I dared to ask what exactly I didn't "punctuate correctly".

Linus Torvalds rant and Async IO (www.scylladb.com)
 

So I think this is ridiculously ugly.

AIO is a horrible ad-hoc design, with the main excuse being “other, less gifted people, made that design, and we are implementing it for compatibility because database people — who seldom have any shred of taste — actually use it”.

— Linus Torvalds (on lwn.net)

First, as database people ourselves, we’d like to take this opportunity to apologize to Linus for our lack of taste. But also expand on why he is right. Linux AIO is indeed rigged with problems and limitations:

The thing that has always disturbed me about O_DIRECT is that the whole interface is just stupid, and was probably designed by a deranged monkey on some serious mind-controlling substances [*].
