Hi guys. I'm 15 and I know some very basic python. However I always somehow end up losing interest and come back after not practicing for a few months. It happens to me with almost everything.
Now my friend and I are planning to learn python programming together. Any suggestions?

Find a non-trivial problem (but not a very big one) that you wish to solve with Python and try to solve it. This is like solving problems from a book, except if it is something you personally wish to see done, you'll be better motivated.

Start really small. I mean really really small. Whatever you just thought of is still not small enough. Think 30 lines of code small. Find a game or something that you believe is possible to write in about 30 lines of code, and give each other such small things to implement. When you're both good enough at this stuff that you can write these programs in less than half a minute per line, step up to 100 lines, and repeat the process. Then 300, then 1000. When you're done with that, you should be really damn familiar with the fundamentals of programming. Now grab yourself a game utility library (e.g. pygame) of your choice and start doing crazy shit with it (again, start with easy things).

After that wall of text earlier I just had to say, I solved all the problems, damn nothing feels as good as when everything clicks after hours upon hours of debugging.

Tomorrow will be spent going over some pen.tests to see how secure I am against sql-injections and other mean things. Now that I got the salt+hash of passwords to work properly as well I kind of want to go crazy with it and do some kind of insane scheme but until I have presented my work on monday I will stick with bcrypt to avoid fucking something up :p

Project Euler is also a good source of problems to solve. Most of the first 100 or so can be solved in ~30-50 lines of Python or less.

A coworker discovered this interesting little fact about PHP today:

Code: [Select]

if ("NULL" == 0) {
    // This is true
}

I understand now why this happens, but I think I'm being generous when I say that it is rather unintuitive that a string containing the word NULL (or null) is equal to the number 0.

Well, more reason to use the === operator, I suppose...

[da_nang]

Code: (My code snip) [Select]

char test[] = "Test";
char * hash;
char randSalt[] = "$1$........$";
salt(randSalt);//Function that randomizes the salt into the given buffer
printf("Salt: %s\n", randSalt);
hash = crypt(test, randSalt);
printf("Hash: %s\nResult: %s\n", hash, crypt(test, hash));

Code: (Output) [Select]

Salt: $1$dJvOI5ee$
Hash:
Result: $1$$0VTwPYhPxYrELvcwegUuu0


Code: (Example code) [Select]

     #include <stdio.h>
     #include <string.h>
     #include <unistd.h>
     #include <crypt.h>
     
     int
     main(void)
     {
       /* Hashed form of "GNU libc manual". */
       const char *const pass = "$1$/iSaq7rB$EoUw5jJPPvAPECNaaWzMK/";
     
       char *result;
       int ok;
     
       /* Read in the user's password and encrypt it,
          passing the expected password in as the salt. */
       result = crypt(getpass("Password:"), pass);
     
       /* Test the result. */
       ok = strcmp (result, pass) == 0;
     
       puts(ok ? "Access granted." : "Access denied.");
       return ok ? 0 : 1;
     }
WHAT IS THIS INSANITY?!?!?

Anyone else use jGrasp?

I can open the thing to write and save code, but I can't compile. When I try, I get this:

Code: [Select]

jGRASP wedge2 error: command "javac" not found.
 ----   This command must be in the current working directory or
 ----   on the current system PATH or jGRASP PATH to use this function.
 ----   System + jGRASP PATH is ";C:\Program Files (x86)\Java\jre7\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files (x86)\Java\jre7\bin".

 ----   Use   Settings > PATH/CLASSPATH > Workspace   (PATHS tab)
 ----   to add directories to the jGRASP PATH.

 ----jGRASP: operation complete.

I thought I fixed this Path nonsense when I got it to come up.

Do you have a JDK installed?

[Just Some Guy]

I have no idea.

Since I had to install java on the computer I'm currently using, I'm guessing I don't.

[Mego]

Yeah, make sure to get the JDK as well as the JRE if you're going to be developing.

My little rant:

I used the FLTK library (which I had experience with from a class) to build a nice, small chess program. It wasn't great, but I'm proud of what I accomplished. I wanted to show it off to a friend of mine. So, I figured I would just compile FLTK for Windows, and use that DLL with an MSVC build of my program, since I had developed the program on Linux. FLTK is cross-platform, and my code had no platform-dependent pieces, so it should be easy, right?

Wrong.

After fighting plenty with Visual Studio (both 2010 and 2013 versions), I finally got FLTK compiled. So, I open up the chess project in VS, add the FLTK DLLs as references, and go to compile. Clean compile. I try to run the program, and I get told that I'm missing a MSVC DLL needed to run it. But wait, how can that be? I check my system32 folder, and there it is. I try copying it to the same folder as the executable. Nope, still doesn't work. Ffs, screw Visual Studio.

Ok, my options are Cygwin and MinGW. Cygwin works, but would basically require everyone who wants to run it to install Cygwin, as well as an X11 server. Not a viable option. So I fire up MSYS, and try to compile FLTK.

Oops, I'm missing cmake. Better install it. Oh, it's not in the MinGW Installation Manager's package list. Ok, install from source. Nothing new. Compiled, installed, and... MSYS can't find it. What the actual fuck. Screw with path a bit, try again. Ok, it found it, but it's complaining about missing some DLL. IT'S RIGHT THERE FUCKTARD. Try a native Windows cmake - it won't generate MinGW Makefiles without erroring out because of MinGW's Unix pathnames vs Windows pathnames.

Fuck it, I give up. I'll just develop it with MSVC directly, without FLTK. Which means rebuilding the GUI and the glue between the GUI and my original code.

I keep hearing about Vim. Sjould I learn how to use it? >_>

Probably. You will probably run into a situation where you can't use a graphical text editor. Vim or emacs is your friend. Learn one of them, just in case.

[Skyrunner]

They both seem hard to learn to use. And I'm not sure of the benefits.

(Also check out the alt text by hovering over the image, hehe)

But yeah, Emacs was apparently influenced in design by these babies.

Just looking at that is giving me a... well, it's more a sense of awe than anything, hehe.
