Summary
Bryan O'Sullivan presents a case study of a small startup that chose Haskell for its server-side code, outlining the advantages and disadvantages of using Haskell to quickly create a solid solution.
Bio
Bryan O'Sullivan is an Irish hacker, writer, and entrepreneur who lives in San Francisco. He has written books on leading-edge topics in distributed systems and functional programming, including "Mercurial: The Definitive Guide" and the Jolt award winner "Real World Haskell". Most recently, he cofounded and is CTO of MailRank, a San Francisco email productivity company.
About the conference
Strange Loop is a multi-disciplinary conference that aims to bring together the developers and thinkers building tomorrow's technology in fields such as emerging languages, alternative databases, concurrency, distributed systems, mobile development, and the web.

If you hadn't said it, I wouldn't have realized it. That info should be in the title, otherwise he just seems like nothing more than a random person talking about a random programming language.

13:15 "An interesting thing about trying to hire people is, you look at ten thousands resumes over the course of the decade and you find that If certain skills are widely distributed in the population they become completely meaningless. So the fact that someone has C# in his resume, it is doesn't tell me anything, it is like claiming that the programmer has a head, it is widespread characteristic in the population, and the possession of a head is certainly a prerequisite to be able to do your job, but it doesn't necessarily tell me if he will do it well. I'm not claiming knowing Erlang or Haskell means you are good programmer, but at least it allows me to filter efficiently".

Really interesting. I'm currently learning Haskell having done a lot of C#. I thought his appraisal was rather sympathetic and fairly accurate.

@brianevans4 3 года назад

36:45 That is a great way to encourage developers to correctly type all constants. If you make a type error, it deletes all your source code. So you better make damn sure you get it right. Haskell isn't playing games. If you mess with GHC, GHC will mess with you

@matthewblott 9 лет назад

I know nothing about Haskell and have never heard of Bryan O'Sullivan and yet I watched this video until the end. Interestingly I'm a seasoned C# guy who has been looking at functional programming which is how I found this video. I thought it was very entertaining - Bryan O'Sullivan is a really good speaker who has the right level of humour (he doesn't laugh at his own jokes - plus his jokes are funny). Thanks :-)

@lukesydenham7620 9 лет назад

Hey dude, if you're looking to get into Haskell a bit more have a look at 'learn you a Haskell for great good'. Its free (donations are greatly accepted) and I'll be working through it soon. Lots of cross over between Scala and f# and probably the fp parts of c#

@matthewblott 9 лет назад

Thanks dude - although one reason for looking at Haskell is to get out my comfort zone. With F# I thought I'd be too familiar with .NET libraries to struggle with things and Scala has similarities with C# and isn't purely functional. I work only on *nix based systems now (including all my C# stuff) - I'm a polyglot these days but am missing "functional" from my arsenal!

@lukesydenham7620 9 лет назад

good plan. so, lyahfgg should more than do the trick. you can look at the coursera free courses on scala too. there's two.

@lukesydenham7620 9 лет назад

Scala's awesome. I did lyahfgg already and I still think it's awesome. So, respectfully, I disagree

LINQ is Mircosoft C# way of doing monads. the books sponsored by microsoft never admits that and most of the design principles of C# is from functional programming. That fills in one more piece of puzzle.

@trejohnson7677 3 года назад

Nothing has changed. The tenacity and "library science skills" are still quintessential. I find it even more important because there's an insane amount of monolithic books that take various different approaches to teaching, competing publishers, and even more VERY valuable information scattered in even WEIRDER places. Much of that information is still stored in resources without much linkage to the "front-end" of the web. Couple that with the onslaught of advertisements, guides and gurus that you have to face a day, it's a lovely challenge to learn anything.

I find assembly easier to write than haskell seriously.

@Silent. 2 года назад

Depends on what assembly you use, like ARM is quite easy to use, but something like X86 is a different story. It’s imperative so perhaps the functional paradigm just doesn’t make too much sense, which means you should probably learn how to use it

@TheBest-sd2qf 6 лет назад

I find Haskell is in fact very easy. There's a few concept you have to master and combine...compare that to learning about classes, inheritance, overriding functions, loops, enumerators, generics, interfaces. Object oriented programming is actually huge compared to FP. FP is basically currying, pattern matching and recursion.

@GiletteRazorsharp 5 лет назад

On the other hand, imperative programming languages I feel are more intuitive by design. It's very easy to reason in the mindset of "do this then do that". Functional programming has a few good properties, but I wouldn't say easiness is one of them.

@jacekjacenty 3 года назад

Are you sarcastic? When you master something you become blind to the problems faced by the noobs. And object-oriented programming is not only about Java.

@jacekjacenty 3 года назад

correction: Haskell is basically currying, pattern matching, recursion, types, lambdas, folds, list comprehensions, functors, applicatives, monads, lenses, non-intuitive order of evaluation, cryptic error messages

@TheBest-sd2qf 3 года назад

@@jacekjacenty would say lenses is not really part of the language itself

@TheBest-sd2qf 3 года назад

@@jacekjacenty I'm just saying it's not really more difficult it's just difficult to change your mindset when you already know a different paradigm. If you started out with Haskell instead of Java for example do you think it would be more difficult?

"Has multiple backends" ...and each of them has a different subset of functionality. One can do FTS but doesn't do transactions. Another does transactions but doesn't support FTS. I mean, who came up with this crap? Have you seen any other RDBMS whose authors were unable to write a proper backend and were shopping for a third party one for years? Because that's what MySQL is. Thank you very much, do not want.

@Maarttttt 11 лет назад

Cool language but the people who love it tend to be elitist snobs, at least at my university. It really ruined the course that I followed on it. There's nothing wrong with loving both Java and Haskell.

@bichitomax 10 лет назад

First: I an not in the Haskell community Second: I am not a ssshole Third: Java still needs to die Fourth: Being one the most use language is not a reason to not hate it, have you seen the Javascript Cummunity or PHP one. Fifth: There are way better alternative to work in the JVM than Java (Clojure, Scala,, Groovy). Sixthl: If you feel unwelcome in the haskell cummunity, is not cuz there are assholes but cuz is just not for you .
