[READMEFIRST] How to ask questions
Homework
We are not here to solve your homework. You have to prove that you have placed effort to solve your homework prior to asking any question here. We are not smarter or at least we don't claim to be smarter than all the posters available all around the internet, so make sure you do your own research before posting your question.
Another thing you need to note which is very important, is that if you don't place some effort to solve your own problems, it means that you're not serious about your field and if you're not serious about your field, we will bash you in a very rude manner. Software Development and Systems Administration and the lot are already polluted with people that have just cheated their way into their jobs. Jobs, that are better suited for people that are quite capable of providing great benefits. Understand that we're not stupid, we can distinguish homework from anything else.
In summary, we will NOT carry you through your career.
At the very least show us a start. Tell us what you're thinking, what you've tried.
Something.
