> Translation is free and instant for web pages. And also very often quite incorrect, and you don't know where. I think the general idea of a "universal language" Wikipedia, that gets flawlessly rendered into local languages, is laudable. But I don't think anybody would ever edit in it directly -- what I want to see is that when somebody edits Wikipedia to add a new sentence, it attempts to translate into the "univer…

I would still invest those resources into documenting more knowledge that currently doesn't exist online on their original languages and immediately translating to English. For better or for worse English is the "abstract" representation of language online and there's so much absent stuff that worrying about another universal format seems pointless.

One way to view this formula is to use the fact that the Beta distribution is a conjugate prior for the binomial distribution. Essentially if you have a Beta(a, b) prior then your prior mean is a/(a+b) and after observing n samples from a Bernoulli distribution that are all positive, your posterior is Beta(a+n, b) with posterior mean (a+n)/(a+n+b). So in your example you effectively have a Beta(0, x) prior and x (“su…

Can this way to view the formula be expressed without the terms beta distribution conjugate prior binomial distribution bernoulli distribution posterior ? Because I could easily grasp that it is a "trust formula" in the way mg described it. But this way to "view" the formula is a mistery to me.

What is everyone's favorite function / formula? Mine is n/(n+x) It has a bunch of interesting aspects: As n gets bigger, it goes from 0 to 1. When n equals x, it is 0.5 As n gets bigger, the difference between n and n+1 gets smaller For two sufficiently large n's, the results are equal. Say somebody told you about a new cafe in town and that it is completely awesome. The best cafe ever. What probability do you assign…

> Can this way to view the formula be expressed without the terms You're asking "Can this way of viewing the formula in terms of Bayesian probability be expressed without any of the machinery of Bayesian probability?".

So Wikipedia asks me for donations but does company off-sites in Switzerland with Google?

Do you think they should have to embrace austerity because they’ve asked for donations? Or do you think they can use donations in lieu of advertising dollars and otherwise function like any other similar company? Do you think it’s possible they were invited by google.org or received donations for the off-site itself? I guess I’m not sure why this is remotely worth commenting on, but it seems to have struck a nerve. I…
