@wat Not too much in the main features, except that Octave is opensource and even slower than MATLAB. But not all MATLAB functions have been ported to Octave. But if you don't want to waste money (or do some pirating) Octave is a pretty good replacement=)
Everyone I've met who is seriously using MATLAB uses it for the devlopment, but for actual usage the developed programs are mostly ported to Fortran or C
It is just a very convenient Sandbox for playing around with matrices. It has a great development/debugging/profiling tools. And the built in routines like fft or matrix solver are almost unbeatable. But as soon as you add some MATLAB code it gets very slow=)
Yup, you read the title right. play the sound of pi.
More specifically, for every digit of pi in the first 1000, map it to a musical note and output the resulting melody to a file.
Example melody showing first 100 digits: http://vocaroo.com/i/s0cfEILwYb8M
Basically, each digit turns to a note ...
Count the number of contiguous blocks within a given 3D input.
Input
The input will consist of one or more rectangles of characters separated by blank lines. Each rectangle represents a cross section of the 3D space. The characters used will be 0, representing empty space, and 1 representing a ...
@ATaco: Excerpt from an email I sent them almost a year ago:
That said, I'd like to note that there *was* one error that took me quite some time to figure out. Near the bottom on this page, where you talk about encoding the codes to bytes.
"If you see at Step 6 of the encoding, we added a code of #7 to our code table. This is our clue to increase our code size because 7 is equal to 2^3-1 (where 3 is our current code size). Thus, the next code we write out, #2, will use the new code si…
A Torrent, as it's name implies, is a file which is downloaded from multiple sources at the same time. Called, "Peers", anyone who's already downloaded the file can then seed the file for others to download it from them. You only ever download a single part from a single source, rarely the entire file, so if one person tries to insert anything malicious, not only would it just corrupt the file, but it wouldn't pass the automatic checksum, which rejects it anyway.
@El'endiaStarman Speaking of suspensions: Did you ever notice the differential bar on the rocker bogie suspension of the recent rovers NASA sent on missions?

The other day, I remembered a program I'd written in C# a while back for fun. It takes a string as input, then outputs that same string, cycling through a rainbow of colours. I've been lurking on PPCG for a while and thought it might make a fun challenge, so I go...
@Pavel Because of me, but does it really matter? I think continuously asking about suspensions is not gonna prevent anyone from getting suspended, quite in the contrary...
