Re: Brewery

I'd be the first to admit that I don't know much about brewing, but I wonder how precise you need the control to be for large scale (ie, not in your kitchen stuff) brewing? If there's "a ton of expensive equipment", there might be a reason for that.

I've been using a variety of different resources as I try to learn a bit of C. Namely: Learn C the Hard Way (Zed A Shaw). The Gnu C Tutorial Hacking: The Art of Exploitation Somewhere along the line you'll probably want to read K&R's "The C Programming Language". It's a little out of date now (the ...

Re: A couple of queries...

If Geany will do much of the work for me, I'm tempted to just use that instead. Not sure how it will handle larger multiple-C-file projects yet, but I'll enjoy playing... Although it can be a pretty big investment to get used to, for projects larger than 3 or 4 files I would seriously recommend you...

Re: A couple of queries...

It's worth bearing in mind that geany doesn't build anything itself, it really is only a text editor. However it does have the ability to run other commands that do build your programs for you, usually GCC or G++ (a front end for GCC). With the appropriate build commands set up (as explained above b...

Re: GPU Processing API

Me saying " all the complaints" was stupidly optimistic. I think it would make many or most of the complaints on this issue go away. With that obvious exception I think my attempt at a fairly neutral summary is for the most part still valid. I wasn't trying to explain the issue in depth at all, just...

Re: GPU Processing API

Does it matter if there is no documentation for the GPU? Isnt the opengl libraries enough? I am not an expert in this area. Whether or not it matters is up for debate apparently, but the argument is the fact that there are other things you can do with a GPU in theory than render graphics, such as d...

Simple RC4 Encrypter

So I got a little bored while avoiding doing exam revision and this is the result. It's a fairly bare bones encryption program that takes a file and a key (in hex or ASCII) and creates a new file with .rc4 either added or removed (as appropriate) from the file name, containing encrypted/decrypted ve...
