One only need look at to notice the great amount of script (and code) questions and varieties of comments to realize that we all have varying opinions about bash programming.

Many questions are very complicated, as are the resulting answers and script recommendations. I've noticed that two fundamental points are invariably overlooked by the questioners, and many of the comments:

C++ had lambda functions!

Posted 01-31-2013 at 01:21 AM by hydraMax (Bits and Pixels)

I'm doing a CS class which forces me to use C++. I was not very excited about this. However, I have recently be greatly encouraged by the discovery that C++ does, in fact, have lambda functions (or, more properly, anonymous functions) at least in the C++11 standard:

Basically, the big deal here is that I can construct new functions /inside/ of other functions, and even capture variables from the context. This,...

Too cool: Haskell Source Analysis

I tried out Haskell's SourceGraph program on the project I'm currently working on. It produces tons of cool dependency / analysis graphs. I saved a summary graph in SVG format at the following location:

Warning: It is only 374K in size, but it is over 22,000 pixels wide at the default size!

The project in its present form uses an event-based model with an oop-like component structure....

gtsh: how to use Google Translate without touching a web browser

Posted 08-09-2011 at 05:49 PM by MrCode
Updated 08-09-2011 at 05:49 PM by MrCode ("Transhlate"? WTF? :p)

I present "gtsh" (Google Translate for the SHell), a tiny(!) shell script that acts as a frontend to Google Translate:

if test -z $3; then
	echo "Usage: $0 \"<str>\" <lang1> <lang2>"
	echo "Translates string \"<str>\" from <lang1> to <lang2>"
	echo "(CLI frontend to Google Translate)"
	wget -qO- "$1&langpair=$2|${3:-$3}"

…while I was still learning the Windows API.

I was experimenting with (very slow) procedural image generation with SetPixel(), when I did something like this for each pixel in the image:

SetPixel(x,y,RGB((x ^ y) * (cr.right - cr.left) * 0.025,
                 (x ^ y) * (cr.right - cr.left) * 0.025,
                 (x & y) * (cr.right - cr.left) * 0.025));
…or something like that (I don't remember all the arguments...
