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. |

Anyone know the best way to study phone interview questions for C# overnight? I have an exciting phone screening interview tomorrow and would like to prepare just in case I"m asked some.

So it's now summer, and as a CS student with zero experience of any sort I figure it'd be nice to get some. Making some money in the meantmie would also be neat.
I've been checking local classifieds and stuff, but am having the common problem of 'MINIMUM 5 YEARS EXPERIENCE.'
Anyways, the few jobs I DO find seem overwhelming and scary. All of them involve things I've never done and therefore do not know how to do. I'm afraid to apply for fear that I do get the job and then find myself lost and overwhelmed.
So I'm here hoping to learn that this is common and that my fears are irrational, I guess.
I just wanna have a compsci job ;_;

Well, considering you've never actually programmed anything commercial, how many things that people would request do you think you'd be able to do right off the bat? 
You only learn when you try things you can't already do. It's normal, and those fears are completely rational. Maybe they do hire you and you can't do it, which is unlikely if you've stuck with programming this long. Hopefully you enjoy it and try it in your spare time and like to learn about it which will make you not only able to do it, but enjoy it.
I would think it worse if you didn't think it overwhelming and scary, which means you may be ignorant to the complexity in some ways.
You'll be fine

What's a good beginner project to work on? I'm thinking about making my own version of tetris and pong which looks really simple (pacman would involve AI and would be next step if tetris/pong work out easily). Would C be a good language for it? I'm most comfortable with C but know C++ Java and Python. Reason for project is because I got rejected from every internship opportunity. It's insane how cutthroat the market is...

That's some serious convolution in that code you've got there. If it were me, I'd just change the href to # and the style to whatever your css disable link style is. End product: <a href="#" class="a.disabled">blahblah</a>. Dunno how to do that with your multitude of "builders" though. Good thing I'm not a web developer!

I'm back. Im having some issues again. Im trying to create a 'webpage' that will automate monitoring calls for quality. Its only in its rough draft form but I've hit a stump. I have a 'onclick' button that I want to 'generate' my monitor notes. I was thinking like making if else statements for each Y/N answer. That way I can just copy/paste from the output field.
So the problem. I have the 'button' made, but im not a javascript guy, and i dont know of an easy way to write this in HTML using basic input methods. This is a project at work, my IT dept recommended Jquery but no access to that and i move pc's regularly. Any pointers on where i would go from from the beginning, or if the following is just terrible code?

use jQuery. It's a single javascript file that sits with the rest of your site's code and will make your life a lot easier.

whelp I can't figure this out...
I was wondering if someone could help explain to me how to utilize bool in a function form. The reason I ask this is because I am working on this tic tac toe game and am trying to make it so that the game keeps going (asking players to make turns) until it reaches to a halt (three in a row) thus ending the game. I can't figure out how to use the boolean operation to a function form...
Here is the code to help me on:

int a = 0;

appreciate the help
btw fyi: You can ignore some of my coding in the main function (block of code above my comments). I understand it may not be "consistent" but I was more worried on making the code work. Once I can get the whole thing going then I will go around and clean it up a bit to make it nicer.
btw how is my coding "style?" Is there any bad "habits" that I should avoid that is present in my work?

off topic: What situation would call for you to use array over vector? Vectors can do everything an array can but better it seems...is it more efficient to use array on a small memory managment or something?

sorry for cluttering :/

boolean is not useless. It might look useless from a computer point of view (and that's why a lot of languages actually define bool only as a type but use int internally to process), but from an engineering point of view, boolean suddenly becomes VERY interesting, because it prohibits prevents a lot more syntax errors by making them actual errors (e.g. if(x = 3) instead of if(x == 3) becomes an error instead of accidentally setting x to 3 and always being true).
protip: have a look at the switch statement instead of your if elseif elseif elseif elseif elseif. Your code is hilariously unreadable :D

I wrote this as a beginner's guide to programming. It is basically a hands-on start for Ruby.
If anyone is interested in learning to program I hope my blog can help!
And for any experienced veterans - feel free to improve and critisize it if you see fit as well.

That doesn't work. You can't do A == B != C, you would have to do A == B && B != C.

Did anyone previously beat the speed of MD5 with their own custom hashing function? The reason for custom hashes I'm trying to use is purely speed, a few collisions or impared security are not an issue. I only need speed because I'm creating hashing tables. I've created the most simple function I can imagine in pseudo code:
to_be_hashed_string(string)
index(string)
Array convert => a=1, b=2, c=3 and so on until z=26
for loop => each substring(to_be_hashed_string, i, 1) start with i = 0
index.add => pow ( convert[substring(to_be_hashed_string, i, 1)], i )
end for
In each iteration the integer i will be incremented which stops many collisions thanks to the Exponentiation (pow) function which is calculated over the convert array number.

} appreciate the help btw fyi: You can ignore some of my coding in the main function (block of code above my comments). I understand it may not be "consistent" but I was more worried on making the code work. Once I can get the whole thing going then I will go around and clean it up a bit to make it nicer. btw how is my coding "style?" Is there any bad "habits" that I should avoid that is present in my work? ********* off topic: What situation would call for you to use array over vector? Vectors can do everything an array can but better it seems...is it more efficient to use array on a small memory managment or something? ************ sorry for cluttering :/
I'm terrible at programming, so I won't comment on much, but it seems like your choice() function can be replaced with:
+ Show Spoiler +void choice()
{
tictac[(a-1)/3][(a-1)%3]='X';
board();
}
also, are you using global variables? Otherwise wouldn't you need choice(int a) instead of choice()?

stick to int, don't use float, that's stupid if you're aiming for speed  also, try less cluttering. a simple:
int hash(String string) {
int hash = 0;
for(char c : string) {
hash = hash * 31 + (int)c;
}
return hash;
}
will probably suffice. Also, if you recalculate hashes for the same string repeatedly without mutating the string inbetween, it might help to use a wrapper data structure, which calculates the hash value on creation and caches it. Then you can simply reuse it and don't have to recalculate over and over.

Hey everyone ive recently been becoming more and more interested in learning the C language as a start point as personally I just really love the thought of being able to just create things Id need or just want to (hell even maybe at some point make some PSP or DS homebrews for myself as a little project too). I have a PDF book on C and I want to get myself more familiar with Linux.
ATM I have Ubuntu installed but I feel like its to Noob friendly in the sense that I dont feel pressured to actually have to get used to terminal am I being ignorant? Is there any other Linux distros that would be better to force me to learn things without being completely thrown down a creek with no paddle? A friend told me Gentoo if I want hard times since you are forced to compile everything and another said Debian but didnt really elaborate
also whats your guys Distro of choice?
