"We don't address this in the post, but adding :while conditions is quite a fun challenge." Eurgh, I hate the common Clojure habit (you see it in for, doseq, etc. loops, and in domonad, which is annoying in other ways) of abusing binding ve

Surely the ambiguity is likely to matter in actual programs?

Macros seriously take in a string and output another string? That has to be formatted correctly with newlines and indentation? That is bats .

"When and if you need it, you can basically make your own type system, tailored to your application." Only given an exiguous understanding of what a type system is. Maybe if Typed Clojure gets to the state of Typed Racket, sure, you could d

The Clojure type of the object is a map, but for the AST-manipulating part of the compiler, isn't it in fact more accurate to say that the type of the object (the logical type, you might say, rather than the host type) is, in fact, `:if`? A

In the 19th century and before, this is actually, more or less, how professors made their livings, at least in the German system. They were paid on an individual basis by their students. Naturally, you had to teach classes that lots of peop

Seriously, no one becomes tenured at a university by teaching a lot of classes. Not only is that not the "track" to become tenured (the way to do that is to get a tenure-track gig, see how that works?), it will likely detract from your chan

Not directly related to this cheatsheet, but I was reminded by the section on operators: you can combine multiple binary operators to get something a lot like ternary operators. E.g., in ghci: Prelude GOA> let True ? x = \_ -> x

Those problems which lack closed-form solutions might lack another attribute that the Fibonacci sequence has, namely, it's easy to wrap your head around the nature of the problem and to verify correct answers. It's purely a teaching tool. I

"they provide freedom that is literally unavailable in any other" There have been lots of arguments on LtU about this. You can go very, very far with either laziness or lightweight closures. Laziness didn't go all the way with Haskell, when

Well, some people might, indeed, be educated stupid, though I hope to god no actual Stats 101 class teaches people that p < 0.05 = significant, other than as a convention that people might want to be aware of when they encounter the phr

by kenko 14y ago
Yeah, the point is apparently just that unthinkingly accepting p = 0.05 as your cutoff for significance is moronic (this point is utterly uncontroversial among thinking humans), whereas the labels make it seem as if he's trying to say somet

Yes, that's so, at-willness of employment and unions are separate. I nevertheless believe it comes from the same impulse, because, in general, the employer is in the stronger position than the employee. (Not always, of course, and it's cert
