EPTMy familiarity with programming languages is limited to Scheme, Python, Java, and C. What reasons are there to pick up others?

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. | ||

Well, I started learning haskell to broaden my horizon so to speak as I am a bit tired of java/.net object oriented EE bullshit. It is not like it is objectively superior to all other languages, but haskell is very fast (not as fast as C), succinct very easy to develop bug free code with. Whenever a haskell program/module compiles I am much more confident that it is bug free than when I compile a java or c program/module. In my opinion, if you are familiar with the languages you mentioned, you have no reason to learn a new language unless you find it enjoyable.

You learn new languages because you're interested in learning the nuances of the language that open your eyes to the limitations of other languages. But in most cases for most programmers, at least relatively new ones, there's a lot more to be learned from continuing to learn and program in a very broad and common language like Java, Python, C/C++, Ruby, etc. and going really deep into projects there, because you'll be getting concrete experience with a bunch of different, and likely more advanced projects. And on the same vein, learning like that really only matters for computer scientists - theorists. You only learn different ways of thinking and approaching the problem. It's not really improvement if few of those nuances would be ever even be slightly relevant in your daily programming. In some cases it's detrimental because now you want to apply your new knowledge so much that instead of getting shit done, you keep looking for the "best way" to do it. Learning is always recommended, but you definitely do not have to do that by constantly learning new languages, and you should definitely not feel like you are superior because you learn more languages than other people have learned. On a side rant, I also dislike how hardcore they're trying to make programmers feel by calling some hackers or ninjas or superstars or something... and it's kinda worked. | ||

Lateral knowledge isn't necessarily improvement. His question is more "what does this do better than the others." If I can do the same thing three ways, who cares? If one of those ways does it faster / uses fewer resources / etc, THEN someone cares. | ||

You already know Scheme, so you have an understanding of why functional programming is an essential programming paradigm that all computer scientists should understand. Fundamentally, what Haskell brings to the table over Scheme is that its strong type system bridges the gap between regular software development and formal verification and mathematical reasoning that your CS undergrad will teach you. Pragmatically, the Haskell ecosystem is incredibly rich for a non-mainstream language. There are a ton of resources to help you get started (http://www.haskell.org) and the library/package system (cabal) is robust. | ||

My apologies if it wasn't clear. I'm much more interested in learning how to program rather than learning a specific language, but if there's practical use in programming in a particular language, I'm interested now (rather than later, when I can learn leisurely) On April 17 2013 10:40 Kambing wrote: You already know Scheme, so you have an understanding of why functional programming is an essential programming paradigm that all computer scientists should understand.

I'd heard Haskell is popular in academia but never really knew why, apart from the lazy evaluation aspect. And what about Ruby? Is it mostly just because of Rails and web development? Why Ruby over other languages? | ||

Someone can correct me if I am wrong, but rails allows you to get going with a product sooner which reduces costs at the start, but has issues with large products being slow if they get popular. This makes it attractive to more risky projects and startups since if the product does well, you should have enough money to do something about the weaker performance, but if it does not work out it cost much less to develop. | ||

Pretty much this. Ruby isn't fundamentally different from Python so preference over one versus the other (at least from a pure language perspective) is a matter of taste. Rails is a good web framework and what many people use Ruby for (and then consequently become Ruby converts down the road). | ||

Well first you need to write a spline detector to comb the VHDL for the appropriate interface to allow you to successfully override a pointer to a pointer. You can then traverse the ether until you find the appropriate API and take over the keyboard. Easy. | ||

Well if you know of a pre-existing backdoor and can have the steps written out for you, then no. If you want to come up with your own way of doing things you'll need an understanding of: networking, low level programming, hardware, and the inner-workings of whatever OS/software you're trying to gain malicious access to. So either, "hacking another computer" is so unrealistic that it's not a thing or you have years of study. | ||

Parsing >> correctly (i.e., as the closing brackets of a template rather than left shift) is a C++ 11 feature. I believe several compilers already did this as a (non-compliant) language extension. But now it is standardized as it should be. | ||

As scholars, we have to assume his intentions are purely educational and help him. You just need to write up a short script using visual basic that bypasses the hypervisor and then unhashes the md5 password on the computer before you set up a persistent server trojan on the hacked machine to remote into it using openssh. Of course the details will vary on what OS you're trying to hack. | ||

If I can do the same thing three ways, who cares?

"His question is more "what does this do better than the others." " is that not a search for improvement? that he seems to be asking whether its worth it? again: "If I can do the same thing three ways, who cares? If one of those ways does it faster / uses fewer resources / etc, THEN someone cares." is this not a search for improvement? which requires exploring new languages? The exact question is stated to every single believer of religion from an aetheist, proove it. how do you know that C is among the quickest, if not the quickest, language out there? its because you can proove it. but being able to proove it to someone means that you have explored that language. One thing this does not tell you is whether it truly is the fastest. Besides on another note, since when has 'ways does it faster / uses fewer resources / etc' ever been the only way of measuring a language? there are plenty of languages created for design problems, that are not as quick as C. I see plenty of reasons to use and not use Java over C++, same could be said about C, python and scheme. There are other languages that could be given the same reason. | ||
