Programming Languages...

[Overlord Drakow]

I don't know computing languages, but I know coding for mathematical software if that counts? One is called LaTeX and it's basically used to write up mathematics (it's much better than Microsoft Word for documents which has lots of maths involved). I'll spoiler an example of the coding for it.

Spoiler:

\subsubsection{Third Law: The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.}

The special case of a circular orbit shall be considered first. Then the more generalized elliptical orbit case will be tackled.

\subsubsection{Circular orbit case}

Start off with equation 5 from the polar coordinate example in the previous section.
\[
v = \sqrt{\frac{K}{r}} \Rightarrow v^2 \propto \frac{1}{r} \Leftrightarrow r \propto \frac{1}{v^2}
\]
Consider the period of the orbit;
\[
T=\frac{2\pi r}{v}
\]
Squaring both sides and then substituting $r \propto \frac{1}{v^2}$ gives;
\[
\frac{r^2}{v^2} \propto T^2 \Leftrightarrow r^3 \propto T^2
\]

The other one I know is for an engineering software called MATLAB.

Spoiler:

%This calculates the potential of a galactic disk and gives the velocity as
%a vector.

R=1;
for n=1:100;
r=n/100;
P=@(x) ((r*cos(x).^2 - cos(x).*(R^2 + r^2*cos(x).^2 - r^2).^(1/2)).^2 + (sin(x).*(R^2 + r^2*cos(x).^2 - r^2).^(1/2) - r*cos(x).*sin(x)).^2).^(1/2);
V=2*quad(P,0,pi);
%This is a numerical integration method known as quadrature.
end
r=0.01:0.01:1;
plot(r,V)
xlabel('r')
ylabel('Gravitational Potential')
title('Plot of Potential against distance from point P to centre')
F=V(1:99)-V(2:100);
%This calculates the centripetal force by taking the gradient of the
%potential
r=0.01:0.01:0.99;
v=(F.*r).^(1/2);
%This gives the velocity as a vector.

AHHHHH OMFG MATLAB!
People come into work with that and are like, it isn't working. I look at it like, da fudge?

To someone who has never used it and has to try and troubleshoot it, it is tough. Normally a problem with the license server but still! ;;​

Mathematical software counts... But I wouldn't really consider LaTeX "Mathematical software". While it's true that it can render advanced mathematics well, it is actually primarily used for documents and articles. When you compile it into a PDF, it is beautiful.

If you know LaTeX, you should write a resume in it... Anyone worth their weight in gold in the software industry will probably recognize it, and if they do, they will be impressed. :D

I used to hate MATLAB when I first started out with it lmao. But by the end of my degree I actually came to love it looooool. It's a really powerful piece of software and I'm glad I have experience with it.

I might take your advice on that then!

Edit: And here's some LaTeX output for those who are not familiar with it;

You forgot a couple of non-mathematical things about it to show it's capabilities. :V

It makes very nice looking documents from very little.

This can include subheadings as well

\section{Auto generation of a Table of Contents}

/tableofcontents makes a lot of work pretty easy

\end{document}

This generates a PDF that looks something like this:

Spoiler:

And yes, those red outlines on the table of contents are clickable links that bring you to the right section of the document.

I compressed it all to one page because I didn't want to import more than one PDF page into GIMP.

As you can see... It's nothing too special, but with more in the paragraphs, documents look awesome!

I use C++ since 3 years and it is very useful for me to do my programming works easily. You can do whatever you want, and everything tends to flow simply.

 

[Serene Grace]

Within the last eight-ish months, I've learned: Javascript, C, C#, C++ and I'm currently teaching myself Ruby and Python (don't ask why, they're hopelessly outdated!). I mostly use C# (combined with ASP.NET) for web development work, although I can also develop native Windows/Linux applications. I just find web development more fun!

This is my first post here since: June 25th, 2011. Wow.

 

[twocows]

Primarily C. I am also proficient in Python (including PySide, which you should all definitely look up because it's awesome) and Java. There are plenty of other languages I have a passing knowledge in, but these are the only three I would consider myself proficient in.

 

[rainbowism]

Since I usually only work on Windows native applications, I only use C++ and C#. I'm not too experienced in making efficient code in the first couple of revisions in C#, but that's just something to be learned.

Other than those, I've only messed with PHP and Python, which didn't turn out too well.
