Reminds me of the old iTunes shuffle thing. When it was first introduced it was actually random but too many people complained it was broken when they heard the same artist multiple times in a row so they rewrote it as a shuffle algorithm that would feel more random than actual random.
Just goes to show, we don't actually want random, we want variety.
There are two basic ways of doing "random" songs:
The strategies are different, but I'd argue that they're equally "random."
I've got a cheap Chinese aftermarket head unit in my car that uses strategy #1, and it's mildly infuriating.
Yeah, but all modern music platforms use a more advanced random, where it will avoid putting two different songs by the same artist in a row for example. But it's still based on the second strategy you wrote.
This seems somewhat flawed. Lets say you have 90 songs by Vengaboys, and 10 songs by Slayer in your playlist. In order to play every song without playing Vengaboys back to back, you'd need to play Slayer 4x more often than you play Vengaboys.
Reminds me of an article I read long time ago of the need in computer games to tweak percentage chance of success and failure, because if it is true as presented 80% success rate players think it should be "almost always" and complain when one fifth of attempts fail.
Me when the weather app says 80% chance of rain, so I go everywhere with an umbrella but it's overcast all day long. Then it says 15% and I get rained on while walking to the store.
I'm never going to learn.
I found out recently that those percentages actually mean 80% of the local AREA would have rain and 20% would not. Meaning if there is a chance of rain in your town at all it’s likely raining somewhere even if it’s just a tiny drop or two.
So if you don’t want to get wet at all bring an umbrella if the chance is over 0%.
Source: was talking to a meteorologist about this exact thing.
Well rain chance is a compound probability it's the probability that it will or will not rain multiplied by the percent of land hit with rain. Like if 50% of an area will be hit and there's an 80% chance it will rain the number the weather Channel will give you is 40%
Chance of rain is calculated based on two things: Meteorologists' educated guess on the chance of rain, multiplied by the area that will receive rain, in the event it does rain.

Pokemon players are very versed in this. This is why I only use 100% hit rate moves.
In gen 1 that would be only Swift, Bide and self-targeting status moves because every 100% accuracy move can miss due to a bug (1/256). Fun fact: you would actually be able to beat the game with these 2 moves because Bide, in gen 1 only, bypasses Ghost's immunity to Normal moves.
Hot take. FireRed > Red so I never need to play gen1 even if I am feeling nostalgic.
Mechanically, the remakes are objectively the better games and they also offer more gameplay-wise with new moves, more logical movesets, abilities, nature, actual EV system. The next big improvement was the physical/special split in Gen5.
I still play the gen1 games from time to time tho. They are hilarious.
It’s a big complaint for new players to Baldurs gate 3. People think a 95% chance to hit won’t fail but it does sometimes. Just the luck of the dice.
'drop rates' are the same thing. 10% chance doesn't mean you will see it drop if you run a mission or defeat that boss ten times.
Or thinking that if you didn't get the drop in 9 attempts, you're practically guaranteed it in the next attempt.
Nope, still 1 in 10 chance.
In most simple written RNG calculations, past failures do not guarantee future success.
I believe some games will keep a tally of failures and award a successful loot after x failures to avoid frustrating players.
BG3 literally has setting for this.
Don't use it though. The karmic dice system works for enemies too. So if you enable the system your rolls will fail less often but so will the enemy's dice rolls. With karmic dice on I find the enemies crit me more. Especially on tactician mode.
Yeah Pity systems are quite common Also used in loot boxes to keep you buying with the terrible odds they have
I learned this very VERY well when I played Ragnarok Online in my teens.
There was a huge fight about this on The Battle for Wesnoth
Same thing happened with the iPhone shuffle. People complained it wasn't "random enough" and would often end up calling members of the same family and/or household in a row. So they rewrote that algorithm too.
Wait, what?! There's a call a random person feature? What a nightmare
Those were the best days of Apple. Steve Jobs literally titled the feature "Less Random".
It’s not just about not wanting random, but randomness is actually very hard to create. Every random number is actual pseudo random
Some basic breakdowns of this concept:

No, there are true random sources in a computer. Any outside input can be used to generate randomness. Mostly user input, but temperature fluctuations can work as well, if the sensor precision is high enough.
Also the argument is only correct on a technical level for PRNGs. Choose a 65535 sided dice and make the instructions a thousand steps long and you'll have a pretty hard time to deduce the instructions from the generated numbers. Not to mention how long the list of numbers needs to be for the attacker to start guessing.
It is all based upon calculations with known numbers.
A computer can't create a number out of nothing.
That is why Cloudflare uses lava lamps to generate random numbers for their cryptography. And even those aren't fully random.
Modern cpus actually do have trng hardware built in. So yes, modern computers can create numbers out of nothing, because they have specialized hardware to do so
No, CloudFlare doesn't use lava lamps to generate random numbers, that was a marketing stunt. Using a camera in a completely dark room is a better source of entropy than one pointed at lava lamps.
Also, nobody is saying that computers create a number out of nothing. The environment is a great source of entropy (temperature fluctuations, user inputs and so on) which are then expanded into a larger amount of entropy through CSPRNGs.
Why is that? Naturally occurring or manufacturing-related impurities in the optical chip?
All digital cameras are imperfect - there is always a bit of noise, but usually it doesn't come through since your scene is bright enough to make small amounts of noise imperceptible. In a completely dark room the camera still tries to get data from the photo sensor, but the noise (created by temperature fluctuations, imperfections in the chip itself and so on) is all you get. You may theoretically be able to predict the noise on short time scales, but it's a chaotic system.
For the purpose of shuffling a playlist pseudo random is indistinguishable from truly random in all the ways that matter anyway.
This is an irrelevant distinction for any case where you aren't worried about someone reverse engineering the algorithm and seed by logging output. Any half decent PRNG's output will be statistically indistinguishable from true randomness.
Well, yea.
