So casual, doesn't even mention GLSL. You know, the language Blockland's shaders run on.

It works but it is very limiting once you're ready to explore deeper, and customization of the environment is nonexistent.
I know there is some Eclipse plugins for Arduino if that's up your alley. I don't have much experience with Arduino development as an Arduino. I've used the boards before because they were available and easy, but I was flashing my own programs to them and not using the Arduino libraries, which once again have a lot of problems for people looking to go beyond the hobbyist level.

I mean I'm still only doing hobbyist stuff and fun little projects but I just really hate the Arduino IDE. I've never used eclipse that much except recently for a networking project in Java and I found eclipse to be pretty nice. I'll take a look at the eclipse one. I found an Arduino IDE plugin for Visual Studio which is what I have the most experience in but it seems like it's just cobbled together.

--- Code: ---/*
A program that adds up the sum of fractions from 2 to 30 and compares it to 1, using nested loops.
Written by Silico Deoxy on October 31, 2015
Version: 1.0
Language: C (gcc target)
*/
#include <stdio.h>
int main(void){
int itsum; /* Used to mark the iteration at which the sum loop is at */
double sum, /* The sum of the fractions */
d; /* The denominator */
for (d=2;d<31;d++){
sum = 0;
itsum = 1;
while (itsum <= d){
sum = sum + (1 / d);
itsum++;
}
if (sum == 1)
printf("Adding %lf 1/%lf 's gives a result equal to 1\n", d, d);
else if (sum < 1)
printf("Adding %lf 1/%lf 's gives a result less than 1\n", d, d);
else
printf("Adding %lf 1/%lf 's gives a result greater than 1\n", d, d);
}
return 0;
}

So we are doing nested loops in our class and I wrote the code above.
For some odd reason, I get some weird results for numbers that do not add up evenly into 1.
Compile it and look for yourself, it's the craziest stuff.
ZSNO:
Yeah, precision of numbers is finite. If you replace your == with
--- Code: ---if (sum - 1 < 0.000000000000001 && sum - 1 > -0.000000000000001)
--- End code ---
it gives the expected result.

Heh, yeah, kinda wished our prof taught us that now.
