First Advent of Code visualization this year:

https://movq.de/v/e14086cc1c/MVI_8057.MOV.mp4

It’s for day 8. Don’t look if you don’t want to get spoiled. If you don’t know the puzzle, you’ll hardly understand what this is doing – but it’s fancy and colorful and fun to look at, right? 😅

This is Java 1 (AWT) running on a Pentium 133 on OS/2 Warp 4.

In-reply-to » So, AI cheaters have ruined the global Advent of Code leaderboard:

@movq@www.uninformativ.de That’s really disappointing 😢 Even before so-called “AI” (Artificial Incompetence) became “more of a thing” I was always astounded at how quick some of the solutions were coming out! 🤣

So, AI cheaters have ruined the global Advent of Code leaderboard:

https://old.reddit.com/r/adventofcode/comments/1h9cub8/discussion_on_llm_cheaters/

And they don’t even try to hide it anymore.

At this point, any kind of speed contest or ranking has become meaningless. Seeing this kind of behavior is sad and probably unavoidable, because there will always be a few who spoil things for everyone.

The only way going forward, I can think of, is to remove the global ranking and just have private leaderboards. Basically what these two people have said:

Cheaters won’t get public attention anymore. AoC won’t be “officially” ruined by cheaters anymore. If you want to do a speed contest, you can still do that in private leaderboards.

(Honestly, I’d prefer it if AoC didn’t have any kind of ranking anyway. I’m not really fast enough to compete, but it’s always at the back of my head. And last year I made rank 116 once, so it’s not completely impossible. All this creates a lot of pressure that I have to fight and try to ignore. 🤣)

Was just catching up on all the LinkedIN garbage that is well umm garbage 🗑️ One was from a candidate I interviewed, so I had to reply to that 😅 – Anyway…. Saw this random post in my “notifications”:

How do land that job with a Unicorn

First off, you’ll have to define what da fuq a “Unicorn” is! 🤣 My understanding a Unicorn is a mythical creature with a horn on its head and wings 🪽 🤦‍♂️

“A minimalist social network powered by plain text files”

My brain keeps shortening this to “a socialist network …” and then jumps to “uhh, large parts of the US won’t like this” … 🤦🤪

In-reply-to » Problem 2: Your SSD-backed database has a usage-pattern that rewards you with a 80% page-cache hit-rate (i.e. 80% of disk reads are served directly out of memory instead of going to the SSD). The median is 50 distinct disk pages for a query to gather its query results (e.g. InnoDB pages in MySQL). What is the expected average query time from your database?

@bender@twtxt.net I reviewed my solution and it’s pretty much spot on! 🤣 the order of magnitude performance is anywhere between 1-10ms

You can call it whatever you want, that’s the beauty of it. There is no need to set a “standard” for this. To prove it, I will setup one feed, and name the file “sørenpeter.txt”. 🤭

Less than 30 minutes for Path of Exile II, and the queue of players waiting for the servers to open the gates is now at 22,525. More than 1 million have purchased the early access to the game. It is going to be a rough ride!

@prologic@twtxt.net 6ms, so extremely slow! :-P

  • 80% pages cached
  • 200us SSD reads
  • 100us Memory reads
  • Query time:

PhD level science questions? (+1)
niftydude an hour ago
A PhD level science question is a question that can only be answered by scientific research and experimentation.

And no, by “research”, I do not mean googling.

Literally the whole point of a scientific PhD is to perform experiments and study to answer a specific research question that no one has looked into yet.

Whilst ChatGPT can probably can answer “PhD-level science questions” with the same generation of plausible bullshit it answers all questions, I very much doubt ChatGPT can answer PhD-level science questions with any sort of accuracy.

It can’t do that without performing experiments (that in some cases might be complex enough to last years).

Just more of the marketing BS silicon valley seems to be full of these days. Remember when California was actually making products that benefited society as well as making money?

In-reply-to » Fuck me dead, what a giant piece of shit. On my Linux work laptop I have the problem that some unknown snakeoil "security" junk is dropping any IPv4 connections to ports 80 and 443. All other ports and IPv6 seem unaffected. I get an immediate "connection refused" when trying to estabslish a connection.

It just worked fine like nothing had ever happened when I booted my laptop this morning.
