I can't count the number of times I've googled for simple commands like "how do I revert an uncommited file to its original state"? hg revert bla.txt git ??? ... and I would still have to google for it (it's something with HEAD

You're forgetting about OTP, Erlang's battle tested framework that covers about any edge case conceivable in a concurrent world. By themselves, you could probably produce hacky actors, pattern matching and hod code swap implementations in m

I thought this would be about rewriting the core HTML renderer or JS engine in Haskell. As it stands now, is this not just the "chrome" around WebKit?

js minifiers not only remove whitespace, they reorder execution paths, eliminate useless declarations, identify unreachable code [1]. Reformatting a minified js file is not going to produce a much better result than disassembling a distrib

Absolutely agree. I would never be able to take anybody seriously (in terms of hiring them) who can't spell or get basic grammar right in my native tongue, but this tends to be quite common in written English. How much can one infer from th

The only thing that has changed is that the compiler has got better at identifying code that is recalculating the same value over and over, and gets rid of that code. i.e. the compiler identifies pure functions and tries to move t

Partly, sure. If I had to write some C again I would surely try to do it as functionally as possible, and with the added experience I have gained in the last years I would now probably be a better overall C programmer. But had I sticked wit

It's absolutely doable in HTML+Js - I've written a TableView in GWT that utilizes the exact same principle and was actually inspired by Cocoa's TableView API. It could render thousands of rows (or however many) utilizing only a few actual d

Automatic memory management, instantaneous compilation, no portability issues, (easier) polymorphism. Maybe weeks -> days was an overexaggeration when it comes to C -> Java but I definitely experienced a big productivity gain, and i

So, Java's HashMap.get() should throw a checked exception whenever the value is not found in the map? That would sure eliminate a lot of boilerplate code :) Aren't exceptions meant to be used for, well, exceptional cases only, i.e. when n

Well, it depends. For example, look at core.logic and show me something comparable in Perl or Python. The ability to just code up a DSL in no time, with the same syntax as the rest of the language is a really powerful tool, and I've yet to

Sure, but a 3x faster programmer will still be more efficient than 3 other programmers, because there is no communication overhead and opportunities for misunderstandings. I would rather hire somebody really good for $6k / month than 3 peop

Good you're not a manager then. When I switched from C to Java, I experienced a considerable bump in development speed. Just the collections framework was a godsend, not to mention things like GC etc. Quite literally I would write things i

At the price point we can afford? Just a quick note: from personal experience, I've been a lot more productive in Clojure than in Java, and I have written a lot of Java code. Things like the REPL, STM or FP speed you up a lot, I would say

Yeah, I was overgeneralizing - what I meant were industrial Californian tomatoes. The taste is probably much better in other regions of the US. Also it probably depends on what chain you buy them from - it wasn't Walmart but it was still so

Coming from Europe, when I was in America (CA) 3 years ago I was shocked that supermarket tomatoes just didn't have any taste; literally, they tasted like water. When I tell my friends about this they think I surely must be exaggerating. Ye

This problem has already been solved in the Haskell ecosystem [1]. For example, you get typesafe URLs so that if you have a standard query like myapp.com/person/345 you can't mistakenly misuse 345 as an article id. Every input string is tra

For all my love of Clojure, having used its STM implementation I can wholeheartedly agree with this. Having side effects in a transaction occur more than once because you didn't pay attention is a real pain to debug, mostly because the tran

Could you give a concrete example that shows why Haskell is constraining?

by pka 14y ago
Yes, but without pattern matching and a do-like syntax sugaring they are close to useless, unfortunately.

Managers like you are the reason why I quit my day job and started a thing on my own. Best decision I ever made.

Thanks for the comprehensive reply; however, a quick search turned up a couple of small, portable and embeddable Lisp dialects (Hedgehog, PicoLisp, ECL) that all seem to target the same niche Lua is apparently designed for. Admittedly, Lua

The same thing in Clojure (untested): (doseq [[a c] (zip ["dog" "cat" "bird"] ["brown" "black" "red"])] (print "See the " c a "?")) Haskell: mapM_ (\(a, c) -> putStrLn $ "See the " ++ c ++ " " ++ a ++ "?") (zip ["dog", "cat", "bird"] ["

An honest question: for which use cases is Lua strictly better than Lisp?
