   For those who want to know more, this topic links nicely into A-D-E theory, Dynkin diagrams, and Coxeter groups. https://www.youtube.com/playlist?list=PL-XzhVrXIVeSVcV9iRJ4S... https://www.youtube.com/playli

   Seems more like "electrophysiology" than "a neuroscience revolution". Would be really cool to have played around with those in school though.

    I wonder why the graduate students went to Zeelenberg first, instead of straight to Eijlander.

    I've heard that as well. I dunno, doubling seems to have worked so far...

    Agreed, if you're doing the same kind of work (or similar enough) over time.

    If, as the article says, "Clients’ Focus on Low Price Is a Major Reason for Effort Overruns", then probably a simpler theoretical explanation can just be the winner's curse. No need to talk about distributions, gaussian or ot

    Here's a tiny tool I like: https://gist.github.com/isomorphisms/9537586 It just prints the first `head` line and then random few rows instead of the top few. For me this is nicer than looking at the top 5 lines ev

    Jeroen, I'm just reading your [1] for the first time now. Are you aware of Dirk Eddelbuettel's `littler`? I believe that might overlap with your Rio tool to some degree.

    It seems like a way to lend scientificity to his opinion. There are other ways of saying smarts>experience. Invoking y=mx+b here seems deceptive.

    Probably everyone knows the math; I just think they're exaggerating the relevance of this model to real life. I'm with the commenter (here) who said that real life is more likely to be an initial-value-dependent or path-dependent

    Let's race 10 miles. I run each mile in 5:59 and you run each mile in 6:00. You get a mile head start. Whoops—this fable is only true "eventually", if the slopes remain the same as t→∞.

    I just mean if you do limit the password length or character type, please remind me at the login screen, because there's no way I will remember across sites who wanted 6-8 characters from [aA9$_!#] and who wanted 12-16 from [a9-].

    As a user I strongly agree that I want to know which of my username or password is wrong. While you're at it, please remind me which characters your website allows, and how many are expected. User/pass guessing by crackers can

    For graph colouring I think the right WP link is Ramsey theory. Also not sure graphs are a "branch" of mathematics, that would be like saying polygons are a "branch" of mathematics. (Branches would be like CA, AT, DG, ..
