Isn't programming a requirement for almost any modern science degree? Almost everything is computerized in almost every field now, so not programming is stupid.

So what languages do people know/are taking?

Not him but I just learnt my first few languages and the most important thing to do is to choose a language which is fairly easy. I did Perl, but Python works just as well. They're
very easy to get the hang of and introduce most of the key concepts. They are also incredibly useful. Then you can learn a harder language, Im doing C++ and it makes me feel like a god among men

I thought C++ was always regarded as a language for beginners?

>>4333044
I wouldn't say that. I coded some development tools for electronics in EE. The neat thing about .NET development is that you can adapt your program in no time. I wrote some tool first as a GUI application on Windows, turns out lots of people wanted to use it, so I just popped it into an ASPX in about 3 days worth of work.

Sure, I would never code some security relevant application in C#, but for rapid development, I've yet to see something that works as piss-easy as .NET.

General use - Python.
Web apps/programming jobs - C#/.NET, Java.
Real-time - C/C++.
Science/Engineering - MATLAB/R/Octave
Computer Science - Lisp/Haskell

A bunch of these are free. You have no excuse not to use at least one of them.

>> No.4333233

I just use MATLAB. If I need C for an embedded application I use MATLAB or Simulink Coder, and if i'm combining it with existing code I verify the whole project with Polyspace.

>> No.4333250

Because my course doesn't teach any programming. we had like, 3 lectures about matlab in our first year, and quite a bit of time using mathematica in our second year, but that's it.

I'll try to learn fourtran or something in the summer when I have time.

At my university programming isn't taught in biology or chemistry courses. chemists get taught to use mathematica and have a tiny introduction to mathcad, but that's it.

Physics students have programming assignments in C though.

I know how to program but I typically dont do it very much anymore. Once you've learned it, it takes no time to learn new languages/relearn old ones anyways.

>> No.4333276

>>4332925
You would think but a lot don't introduce programming at all. I didn't even know what programming was til I got a job and they took the time to train me a little.

Atm I only know the very basics of Python. I like it though. It helps that I do a lot of GIS work so Python makes sense for me.

After I get comfortable with Python is C++ a good choice for me? I tend to stay in the environmental fields (geology, hydrology, botany (wetlands), etc)

Physics/engineering majors should really consider MATLAB (better product - if you have money) or Octave (if you don't). Both of them have an excellent interactive programming environment, which is an actual pleasure to use once you learn it. Also, Wolfram Alpha for reference data.

Way back when I was a Physics major, I would have killed somebody to get my hands on either one of them.

You might be happier remaining with Python. Compared to Python, C++ is a bit clunky and primitive. C/C++ are better choices for embedded programming, where you have to do a lot of low-level memory and hardware register I/O. Also, for C/C++ you are going to have to learn how to use pointers. This is a fatal obstacle for a lot of people.

i mostly use MATLAB coz it's easy and gets shit done. however i heard that most of supercomputers (or some shit) can only use FORTRAN so i'm thinking about learning it better for numerical work. i really don't know much about this stuff that's why i'm asking you, if that's the case with these supercomputer-thingy.
i'm on 3rd year physics (i don't think of numerical simulation as my main field, rather pure theory).

The newest version of MATLAB will automatically run calculations in parallel on multiple cores, if your processor has them. It can also use the GPUs on a CUDA-compliant graphics card (mine has 256 of them) as a po-boy supercomputer. We have applications which need this kind of computing power.

For a product that you have to pay money for, MATLAB is well worth the cost.

>> No.4334421

Stuff I know:
- C++: Hard to both learn and master, capable of both high and low level programming, writing in it is averagely efficient, execution is very fast.
- Fortran: Normal learning curve, ancient language, writing is awful, execution is very fast
- Python: Easy to learn, highly efficient to write, code execution is slow because it's a scripting language. However, C++ and Fortran code can easily be implemented to speed up the calculation (f2py for Fortran, scipy.weave for C++), which makes it a viable candidate for scientific programming.
- Mathematica: Scripting language; internal functions are implemented very efficiently and run fast, implementing C code is easy as hell. Batshit crazy learning curve to the point where the majority of the user base doesn't write very efficient code and complains that it's so slow.
- PHP/PERL: Easy to learn, huge library, nice to write small scripts. I'm not using them very often though, Python pretty much replaced my PHP scripts.

hah. signatured. if you want to program stuff that's any thing related to science and engineering, you would be well of with Matlab (or Octave, if you are poor; or just torrent Matlab if you are not part of some institution). Pretty much anyone who is serious about getting shit done (in these fields) use it.

I would leave C for systems programming, C++ for applications stuff. And python for ... i don't even know, web shit or something? ...and I guess making gui programs if you want them to be slow. Perl is my favorite though for text processing. Also I like Ocaml for making small programs that are completely independent and have no dependencies.

I actually love Mathematica, but I hate it when people complain about it being slow. It's a huge language that can be coded in bunches of different methods, to make it easiest for the user. You can write a code to do something really complicated pretty easily, it just won't run very efficiently. If you want something that doesn't waste the computer's time, write in a more efficient language like C. If you want a language that doesn't waste your time, use Mathematica. Also the "CompiledFunction" function can usually save a bit of time when you're doing simpler stuff in Mathematica. Also using "Do" instead of "For".

Also Mathematica does have a huge mess of functions, but there's little that isn't automatically built in, and the manual pages are very well0designed and helpful.
