Haskell's aeson library, which is probably the most popular way to use JSON in that language, doesn't require any of this complexity or typecasting ugliness. It can derive a typechecking parser for a particular JSON format from an

`zip toss toss` only produces 2 of the possible outcomes. Try `liftA2 (,) toss toss` instead.

Well, you can always assign a different reviewer if your initial choice is taking too long. I usually try to check with my teammates to see who has time for a review before sending them my code, at least if it's something that I want t

It's common at Google to have a few projects cooking that you move between. One reason for this (though I doubt it's the sole reason) probably has to do with the mandatory peer review process for all code, which can cause delays i

There's some info here: http://www.reddit.com/r/haskell/comments/2pnjdk/is_overloade... . tl;dr: The patch worked but was messy/overly complex, so it needs refactoring before it's merged.

It doesn't integrate multiple accounts into a single inbox, if that's what you mean. It works the same as Gmail in that respect.

It's too different from Gmail to be integrated into it. It coexists with Gmail so that you can choose to use Inbox and its "opinionated" workflow, or not. Users who like their personal Gmail workflow probably wouldn't ap

Every existing class A or B share will be matched by a class C share. Most Googlers had class A shares before, so now we'll have half class A and half class C, i.e. twice as many total shares, with the same number of votes as before.

If you don't think it's worth your time to interview twice at the same company, then simply don't. That's a completely reasonable point of view, and I didn't mean to imply otherwise. For what it's worth, Google

The Google lunches are emphatically not a test. It's very rare for the lunch "interviewer" to provide any feedback at all. That usually only happens if the candidate starts spouting racist comments or punches someone in the l

For one thing, it allows your pipeline to both read from and write to the same file, as it defers the output until there is no more data to read from "upstream". For instance, this won't work (it truncates the file for writin

It seems like kernel-space code would be one of the worst possible environments in which to use a dynamic language. A runtime error in that context can easily bring down the entire system; you're really better off sticking to languages

The win for Haskell is that it wears its statefulness on its sleeve. Of course you can, with sufficient discipline, write pure code in any language, though it can be frustratingly difficult in languages where libraries make idiomatic use of

I'm aware of dependent types and, more generally, the strong undercurrent of emphasis on provable correctness in the Haskell community at large. I don't disagree at all with what you wrote, but it's not what I was referring t

While I fully agree that pure code is far easier to maintain than impure code, and the advantages of Haskell are numerous, I think it is a bit strong to state that such claims are backed up by mathematical proofs. Ease of maintenance is a f

The latest version of Cabal (1.18) includes built-in sandboxing support, which alleviates this problem to a significant extent. Prior to that, there were/are tools [^1][^2] for doing the same thing external to Cabal itself. Dependency

Not sure about web applications, but Pandoc [1], git-annex [2], and xmonad [3] are a few examples of successful, reasonably-sized applications written in Haskell. It's definitely worth browsing through their code if you want some examp

This simplifies the type signature, but doesn't avoid the need for `return $ f "unneeded"`, which seems to be the ugly part he was really hoping to eliminate. Also, now you have to write your own lookup function instead of ju
