Thread Rules 1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution. 2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20) 3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible. 4. Use [code] tags to format code blocks. | ||

Most of the tutorials you'll find will be for development in Scala. There's a place here looking to hire CS grads in spring and they specialize in Scala and Play and do what sounds like some interesting stuff with both. I've looked at Play a bit. It seems really neat. I was teaching myself scala but that got sidelined by school. My goal is to learn some of both over the break and apply there in a couple months. | ||

Apart from being fairly biased it's also extremely outdated with it's C# examples - which isn't surprising considering it's 8 years old and languages have developed a lot in that time. The feeling of wanting feature X of language Y when you are developing Z is normal, no matter which language you use. All languages have a lot of features that other languages miss, because all languages specialize in different areas. While a specific feature might be useful, usually using the full language isn't, often due to missing libraries or other missing language features. I do wish PHP had C# style lambda expressions and properties though

His comparison with C# doesn't hold anymore, C#'s handling of lambdas is elegant since C# 3.0, and Python is really not that much more powerful than C# imho. There are even constructs that are obviously more expressive in C# than in Python, like concurrency or asynchronous stuff. I get the "demotivation" bit though. I can't fucking bear Java anymore (which is a way more stagnant language than C# ;D) now that I've tasted Scala. Edit: Haha Morfildur sniped me baaad. | ||

In PHP you can do this:
And in case of an array of objects:
You can also do it with just one function and one lambda:

I really need to start using lambdas at some point. Legacy OS' of my customers have me trapped at older versions of .NET. They still don't look natural to me yet, it's a weird ass syntax in a world that mostly looks like c. | ||

In an enterprise environment it's something that I've come to love. Sure, if I'm trying to script or do something quick and dirty or only for myself, I agree that it's a bit overkill. However, when you have to maintain a project for many years and developers come in and out like a revolving door the verbosity of java is quite nice. | ||

The downside is, it forces good programmers to code like bad programmers. It's not really something that can be changed too. There are nicer "mainstream" "for the masses" languages, like Python, which is both easy and expressive, but every programmer won't be able to code in Haskell, for example. | ||

i think making your assumptions explicit in code (f.ex that this container is not resizeable) is ~always a bonus. dynarray also hopefully will have the added bonus of using stack allocation if the size is small enough. but if that's not a concern, then vector is a safe bet: it's everyones favorite container. dynarray will be a nice addition when the holy binary, GCC, selects it for ascension. | ||

They still don't look natural to me yet, it's a weird ass syntax in a world that mostly looks like c. I must say that I'm not a big fan of lambdas. Just like I'm not a big fan of chaining in PHP. It seems like trying to cram as much code as possible into one line which can make it less readable. Don't get me wrong, I'm all for using anonymous functions and recursion when declaring "variables" but apart from that I think you start introducing too much clutter in imperative languages. | ||
