#53This is hugely noticeable playing/practicing/learning music. Just yesterday playing guitar.. I was fighting playing the wrong note cause my brain was guessing that was the next note because so often in so much music it would be. It was something like 3 notes that are in a particular scale and my brain really wanted to play the next note in the scale instead of the correct next note. In all activities our brain intern…
I play Dance Dance Revolution competitively and it’s extremely important there as well. A lot of people ask me how I’m able to “read the notes that fast”. The answer is always that you build an intuition about what patterns follow certain patterns, and that you never read each note individually. It’s a great combination of some of the sensations you get from playing music, and executing things well in a video game.

osu! - and most rhythm games, I would think - is the exact same way.

#54Although they just discovered the mechanism, we've known that this happens for quite some time. It's something you can take advantage of in UX design, for example, because if you provide a subtle queue before something new happens to trigger the brain, the new thing will be perceived faster.
Progress bars make my application run 50% faster without touching the rest of the code. :)
It's better to appear busy than actually being busy.

#55> Imagine picking up a glass of what you think is apple juice, only to take a sip and discover that it’s actually ginger ale. Even though you usually love the soda, this time it tastes terrible Even brains aren’t safe from speculative execution vulnerabilities
This happened to me drinking soda water, I thought it was just regular old tap water, went to take a huge sip and immediately spit it out in disgust. I normally hate soda water, but that time I especially hated it.
Walgreens sells a sparkling water that inexplicably has artificial sweetener, though it's not sold as "soda" but as "sparkling water." I bought it expecting, you know, sparkling water and the experience of getting a mouthful of unexpected aspartame was... memorable.

This is why people should not serve mashed cauliflower at Thanksgiving without advance notice. (Like 30 seconds, as it's being served, it's fine)

#57I’ve noticed during meditation on external sounds that for any repetitive sound, my brain immediately starts reproducing the sound internally, and then stops paying attention to that external sound and starts scanning the background for other sounds. This is the case for anything from air conditioner whine to birdsong. The meditation then becomes to interrupt the cached reproduction and really listen to every sound,…
My wife always play guitar and even after she stops I hear the song she was playing for the rest of the day. It’s very unnerving. What other parts of reality am I just filling in?
Almost everything outside the foveal area of your vision.

#58This reminds me of the work John Carmack did when he was writing QuakeWorld, which in 1996 was quite playable on a 56k modem! He started off predicting 300ms of lag on the client side, but it was too glitchy when the correction came in. He landed on a more conservative strategy, and his writeup is a touchstone of Computer Science lore for me: https://fabiensanglard.net/quakeSource/johnc-log.aug.htm I wonder if you co…
> I wonder if you could design a game around this by drawing BOTH the predicted motion and a ghost image of the last known verified server position of players, and then deliberately introduce 500ms of latency. The gameplay would then be about tricking your opponents into thinking you were going somewhere you're not.
This would be fun. Maybe call it "Kalman's Revenge" or something.

#59CPUs have this as well, for increased performance https://en.wikipedia.org/wiki/Branch_predictor
Would caching also be a form of "guessing" what's next? Cache hits could be considered guessing correctly and while cache misses is guessing incorrectly.

#60I've seen something like this with speech.
- I have some accent when speaking english but not much. - Some colleagues from my home town have much stronger accents.
When they speak some words in weird ways I find that american colleagues just understand and move on.
When I speak a word in a weird way they'll either laugh, bc it is funny, or just be confused.
I think its because they are paying more attention to my colleagues with stronger accents because they know they have to.
But with me they'll be more relaxed and get caught off guard when I pronounce words wrong.
