I don’t think there’s an algorithm involved actually. Just lovely facts.
Well, there has to be some kind of algorithm. Even picking a random Wikipedia article technically is an algorithm, just not one that adapts to the user
Right, but in the context of social media feeds, "algorithm" always refers to an algorithm for personalised content.
True, but outside CS the word has come to refer to a certain brand of complex heuristics or ML inference.
An algorithm usually involves lots of complex calculations and weights. Picking a number from a pool of numbers at random is as simple as it gets.
In comsci, there are no real random numbers. They are all seeded psuedo-random number algorithms. (Unless you integrate with some third party random as a service setup)
Yes but the common interpretation of “the algorithm” is that of the social media and YouTube style one. Recommending items of interest etc but easily manipulated by bad actors.
Wiki random is about as opposite to that as possible.
That's a common misconception. You can measure a lot of ambient noise and extract entropy. Like time between inputs or how long it took an HDD to seek.
Most modern PC CPUs even have dedicated hardware for generating random numbers from electrical ambient noise. I don't trust them however.
