Hughlander posted:Or if you are using an OO language you just use objects. Don’t expose the internal and keep the overflow / underflown handling to the class. I say this as the guy who has worked on countless MMOs with either 32 bit exp or money and had to deal with or watch the consequences of going live that way. Midway through my career I got the clout to just dictate it as such and life is easier. I agree this is probably the right way to go, but we were talking about whiteboarding (and in my case, a friend who hasn't even learned about functions, much less objects, doing homework), where this is unlikely to be the case. I don't think most whiteboarders want to watch you write 4 classes to create Fizzbuzz.

Last company I worked for requested I do fizzbuzz on an in-person test. The ended up putting me on script maintenance once they found out I knew Bash. I no longer work there.

I want to argue about this. Haskell is a better language for beginners than Python. Because once you master Python, and realize untyped, imperative scripting languages are garbage, you will want to learn Haskell, but it will be harder to unremember the mutability, for loops and gimped lambdas. The cost of learning Haskell is high, but it's lower if you avoid learning Python first. It's like Dijkstra's thoughts on BASIC.

The cost of learning Haskell is high, but it's lower if you avoid learning Python first. It's like Dijkstra's thoughts on BASIC. What are your thoughts on goto's?  Snark aside, the advantage of Python is it's super portable between OS's. I mean so is Haskell, but if you're talking a scripting language for OS tasks, there's Powershell/BASH, but those are OS specific. Granted you could do the same thing with Haskell, but most companies aren't going to look for that. The other thing is Haskell is purely functional where Python isn't, which makes it a bit easier for scripting as well. So basically, if you're going for functional stuff, Haskell is the better choice, but for portable scripts, Python is. Right tool for the job. e: I totally forgot the term for this, but there's a "language" that always has one better feature than a previous one, but then someone decides it's not good enough, and makes a new language that's better, and so on and so forth. iospace fucked around with this message at 16:58 on Jan 28, 2019 |

In some theoretical sense Haskell is a better language for beginners, but the biggest barrier to entry for beginning programmers is lack of inspiration. Most beginners don't find type theory or algebraic identities particularly inspiring. I had a first year prof that introduced Haskell to us and the only effect it had on most people was to make sure that 90% of them never look at Haskell ever again. Haskell itself became an inside joke that lasted until graduation representing a fate worse than death. I'll always advocate getting people inspired, even if it means letting them use PHP or something. The damage can always be undone later, but if you make someone learn Haskell right off the bat you might just kill their enthusiasm all together.

I don't think that learning Haskell as a beginner requires learning about type theory or algebra that much. You can write in the subset of Haskell that is basically equivalent to Python, but faster and with better error messages. Never write a type, put everything in the IO monad, and you're still golden. xtal fucked around with this message at 17:27 on Jan 28, 2019 |

Volte posted:That line of thinking only works if you understand what types are, what they are for, and why the compiler yelling at you every two minutes is a good thing. There's a lot of experience implicit in seeing an error message and knowing what to do to fix it, and in having the confidence to know that what you're trying to do is even the right thing, especially if you don't understand what you're doing wrong. The more abstract the error message (i.e. "variable not found, you typed it wrong" vs "type class context not satisfied due to blah blah"), the less likely a beginner will know what to do. Even experienced programmers are experiencing this pain with Rust's borrow checker. A borrow checker is different, and much much much more complicated than a type checker. Python, being strongly-typed, has a type checker. It's just poo poo. The error messages that you get with `5 + "5"` are approximately equivalent in both languages, but a stronger type system can give you stronger advice.

Elm is probably the best language for beginners out there. - Immediate feedback and cool results (make Super Mario in the browser!) - Excellent error messages - Teaches excellent programming practices (immutability, explicit typing, no exceptions) - Good tooling experience (not as painless as an interpreted language, but teaching that compilation is a thing that exists isn't so bad, and the elm starter kit has always worked on the first try for me)
