Thread Rules
1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution.
2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20)
3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible.
4. Use [code] tags to format code blocks. |

I would just like to mention that Station class has a lot more members than that. But the problem here is that I cannot access the members from the Station objects I created in database.js from printer.js. I am having quite a bit of trouble figuring out how to do this. I have learned how to create a new object of Station in printer.js by exporting Station, but I still can't access the members of an object I created somewhere else! It just spits out 10 x "id: undefined" Can any of you guys help me? You need to change your database a bit:
database.prototype.getStations = function(callback) {
//...
}
database.prototype.Station = function(id) {
//...
}
module.exports = database;

Hello can someone help me? I need to write program in C# that can do functions below.
1)x+y
2)x-y
3)x*y
4)x/y (integers)
5)x%y (balance)
6)x/y (fraction)
7)x2+ y2
I done the 1,3,4,5 point, can someone tell me my mistakes in 2,6 and 7?

Why do you convert input to int and store it in a double variable? Then you try to simultaneously do concatenation with mathematical operations on it...
Take input, do the math and then print the result as string.
Example:
public function Add(double x, double y) {
double result = x + y;
return result;
}
// do the same for divide, multiply etc. do whatever you need in the functions
public function DoStuff() {
string sum = ToString(Add(x, y));
string ret = String.Concat("x + y = ", sum);
Console.WriteLine(ret);
}
What I posted is very simplistic, there are of course better way of doing it (like using C#'s inherent Sum() method).
And you should really store your results in some enumerable variable and then print it through iteration or recursion.

#4 should be different from #6 but you use the same expression for both, why do you expect a different result
#7 you're using Pow wrong, read the reference page

You might want to refer to this :

You need parenthesis like everywhere... Even the addition one will not print the expected value

Is it bad practice to use an actual table name when passing data in javascript. Seems like it would give an attacker free information about your database structure? Or does it really not matter? An example would be:
Ajax({
data: some_array,
table: 'actual_table_name'
});
Thanks!
Time for some buzzed programming, this always goes well. (NOT)

Cool, makes sense. Thank you very much.
EDIT: My late night programming session went very well, was able to kill a couple issues and more importantly I moved a bunch of features and enhancements from 1.0 launch to version 1.1 which will maybe, possibly, could be released someday! (This is a AJAX based Wordpress plugin that I'm working on)

I'm still wrapping my mind around this new concept and the more I think about it the more stuff I come up with to use them for. I mean... it's a function that can return a value.. but keep its stack data! So you can enter the function again, and it keeps running from where it left off until it returns again. Short example if you don't know what it is:
def mygen():
yield 1
yeild 2
yield 3
gen = mygen()
for n in gen:
print(n)
>>> 1
>>> 2
>>> 3
At first glance this might not seem so awesome, it's just iterating right? WRONG! The cool thing is that the generator can maintain its own state! And you can connect many generators together to form a massive processing pipeline. If you're intrigued, check out http://www.dabeaz.com/generators/I just heard generators are coming to Javascript, which made me really excited!
So it's the exact same thing as yield return in C#, I would assume. Though C# likely isn't the origin of the concept. Anyways, it's pretty much an essential concept in C#, whenever you use the linq namespace or IEnumerables in general.
It's extremely useful and allows you to write very clear yet efficient code. For example you can repeatedly apply filters and transformations on a sequence of elements and then shortcut your way out of evaluating all that stuff by finishing with something like Any(), First() or Take(). In which case the filters and transformations are only executed on just as many elements as necessary for the final statement.

Yeah, I've heard about them and I'm planning on learning about those after I'm done with generators.

It seems like the same thing, yes. I've only briefly used C# but I think that when you have an IEnumerable while debugging, and you want to see what's in it, you get a message "Expanding the results will enumerate the IEnumerable" or something like that. Correct me if I'm wrong, but I Imagine that this is because the IEnumerable is a generator that hasn't been iterated through yet (so it doesn't actually contain any values, just information on how to generate those values).

I am curious about the the feasibility of working as a programmer (not freelance) from home. I imagine this is very rare for junior programmers, but I would like to hear from people who work like this or work with others who do.
Would it be worth getting experience with software like SVN to improve my chances?

I'm just an intern so I don't get to do it myself, but I know my company allows significant working from home, even some fully remote employees, so it's not unreasonable.
Version control in general is kind of a big deal though... if you want to work with like anyone else ever at all you're probably going to need to know some kind of 'software like SVN' 
|
Version control is mandatory. You should definitely at least know how to use a version control system. Ideally both centralized and distributed systems.
|
I even use version control on solo projects, if only because it's the lazy man's documentation. 
|
I am overwhelmed by the amount of things I am not even aware of, which is a bit of a problem. Please direct me to any resources you think would be good for me and thanks for your answers
Btw, I have no formal education on this subject, everything I do know is self taught

SVN blows. Git is the way to go

Just use Git and Github when you're developing non-confidential in your spare time and you'll learn in no time. Learning a version control system is mandatory, it doesn't really matter which one, but Git is the least bad.
https://github.com/
I don't find think working at home is worth it because team work is usually more important at work, of course varying per project.
|
face to face communication is still the way to go though but if your on a solo project, it's best if your WFH

I'm in search of someone who is skilled in reverse engineering. The assistance will help bring improvements to StarCraft: Brood War and even other Battle.net(v1) games.
PM me if you're interested!

Programming is one of those things where, generally, people who do it love it in a strange and slightly odd way. I'm also mostly self taught, and I learned a lot of stuff the hard way (like making loads of changes to one of my projects during a coding spree, breaking everything, and not having a backup newer than 8 hours as a firm reminder that version control is good). And nowadays, most programming jobs ask for a github instead of a portfolio.
If you can find an internship or part time job you'll learn a lot, which you can apply to your own stuff.
