I still think you manufacture a (slightly) unfair coin: http://www.win-vector.com/blog/2015/04/i-still-think-you-can... ( The post got truncated by a bad character in my blockquote paste (sorry!). It should b

Closures are used as objects quite a lot in R, as the standard structures are all actually immutable (to first order the only common user facing mutable things in R are variable bindings / environments, there are reference classes like

Okay, here is a completely open offer. Somebody says: "give me $10,000 and I will give you nothing back in exchange." I would call this a scam. Not a very good scam, but a scam.

I'll give the FDA a lot of credit for things like blocking thalidomide from the US in the 1950s and 1960s (looks like Richardson-Merrell was pushing hard for US sales after it had already caused a disaster and been banned in Germany)

My (non-expert) OPINION is: Bitcoin is a scam. I do support the idea of digital currencies (possibly even decentralized), but I don't think Bitcoin is the appropriate flag bearer. I understand the term "scam" may seem rude

Already downvoted below zero (about 2 seconds). I'll stand by what I said/implied: it is hard to co-exist with Google systems (and apparently also with pro-Google shills/apologists). I know this post violates HN standards,

Obviously good email (deep in a conversation) being declared "spam" has been a problem with my business for some time also. I figure Google takes all email in a 2 step process (either intentional or accidental) 1: get a good

Having the luxury of only watching Unicode from afar, it looks like a right horror show. As a mathematician I respect how much harder it can be to work over equivalence classes (especially when you don't have obvious normal forms) tha

I like this NTYP misses a literally perfect work problem (you can solve for the two different sales quantities from the numbers quoted in the article). But this is pretty compatible with the NYT 2012 position that you don't need algeb
