In Haskell and PureScript, `fmap` is a method in the `Functor` class, which is defined by class Functor f where fmap :: (a -> b) -> f a -> f b for which instances should satisfy `fmap id = id` (and you get `fmap (g .

I think PureScript should catch on. The runtime performance story is much more predictable than Haskell, it integrates trivially with the most valuable target platform: JS, it has small output, fixes the warts of Haskell and yet is still pu

I don't really use foldr even in Haskell. It's almost always a performance problem.

You don't have to study its effect system in detail, there's not much to it. Instead of IO a you have Eff e a, where e is a record of effects, using PureScript's records support. The neat thing is that statements in the Eff m

Stack requires package sets (aka "snapshots"), which some kind of CI system (Stackage: http://stackage.org/ ) has to do a daily build job to see if they all build and pass tests together. That requires some money t

I think making sense of the scale of weather would be aided by an accurate world map like the peters projection or something of that nature that doesn't do Eurocentric seafaring things like put Greenland as being the same size as Afric

I do think that educating other people is important, because we don't live forever.

I'd agree. I've been trying to think of why I like orgmode and todoist and toggl aren't the same, it's that I can manipulate it freely as text without being blocked by the structure or hitting a use-case unanticipated by

One thing that will be a factor for a long time is that a piece of paper doesn't require integration to share it with other people, or a battery to be charged etc. It's just a real object representing your ideas.

He just means that great philosophers tend to talk about relationships in the abstract and not historical artifacts that become dated. Murder is wrong is not going out of date any time soon, and yet "murder by electric chair is wrong&q

> Google believes it should not. It's always funny to see someone write that a company "believes" anything. It's a party line. With a company as big as Google of 10,000 it's downright strange.

I believe PureScript solves most of these problems.

I think what you mean by "functional" and what the author means by "functional" are distinct. Are you aware of the distinction?

Buying tickets with RyanAir is stressful due to these kind of practices. They're less aggressive than in the past, when I wouldn't even continue because I just had zero trust in the company, but they're still sly. A sneaky on

There are many points to respond to here. 1. Evan (the Elm author) has pledged to support type-classes, it's on the issue tracker, and because he believes that they are useful. 2. "The academics" is a mischaracterization. I u

The article itself basically says "I break these rules regularly, I'm not perfect either". But I think some people like to point out people's flaws to show off. Orwell's article is sincere.

Indeed, "melting pot" makes me think of think-tanks or a busy "scene" area, it doesn't make me think of an actual melting pot, the words themselves doesn't conjure up the mental image that they refer to, so the

If there's no stack.yaml it uses the global ~/.stack/global/stack.yaml. So you should be able to open any random file and it'll work out. E.g. if I open ~/X.hs and import Lucid, I can just run stack build lucid

This was a trade-off I went with. One thing that I learned from years of hacking on haskell-mode is that adding an option for every little decision adds up to a brittle user-experience. If you want this, enable that. If you want to enable t

The bias is understandable, though. People things are good at are the result of practice from birth, whether conscious or not. Basic neuroscience tells us that. The few people I know who I would consider geniuses in the true sense of the wo

Honestly going blind is a fear for me for everything (never seeing my family or my SO smile again, or the rain, etc.) except programming. It would be hard but things like Emacspeak really make me feel like someone's taking care of the
