How do you think the future is going to look like? do you think is going to be scary than today or better than today? (Technology)

Keep on mind that everything you do today is mostly done by computer, and that everytime something(machine) comes up, it'll be better, faster, smaller and cheaper than the machine before. And remember that 10 years ago, everything was mostly done by hands.

I'm trying to run as the vice-president for the Junior class for next year, and I need two things, can anyone answer them please!!! and thanks!!

1)A Slogan for my campaign, My name is Moises Fonseca, and my famous nickname is Moi. If you can think more than one slogan that would be great!!

2)A poster, I haven't think of a good poster for my campaign, The Poster is 22"X28". All i could think for my poster is My name, little background information, and my slogan, if you have any idea of what to add to my poster it would be great as well.

Well thanks everyone for helping me in my campaign.

I just can do it by email or phone only

I'm doing a project and the project is researching the field of Computer engineer(hardware/software engineer works too!), and i dont know no one who works in this field.

my questions are:

2)what do you do on a typical day?

3)What skills do you use the most?

4)What education or experience did you have in preparation for this career/job?

5)What is a typical career path in this field?

6)do you think this field has expanding or diminishing job opportunities?

7)What personal qualities are important for this career?

8)What are the major rewards of your job?

9)What are the major frustations?

10)Do you see yourself staying in this position/in this career for the rest of th your work life?

11)What advice has been helpful to you in your career?

12)is there anything you'd like to add?

i ask this girl to go to the winterball with me, and she said yes, so i rent my tuxedo, i bought the ticket ($10 for it), and she said she is cant go to the winterball with me, because the AP call her mom, telling that she cant go to the winterball, because she has a "D", and now i dont have nobody to go with me, no even my friends, so should i go to it by myself or stay at home? by the way the winterball is tomorrow, and the other question i think she plan this before, because i was on myspace, and i decide to check her page and there were a comment saying this "what happen to the guy, that you are going to the winterball", and then the same person left another comment saying "that a good plan, tumps up for jackie", and i try to go that person page and it was private, do you think she plan it? or what?

ok let said that you are 15 years old and you like a girl of the same age, and then she become your gf, so then you love her or like her?

Saben cual es la diferencia enter decir sos un pniche a un mejicano, y decir sos un pniche a un nicaraguense?, por sierto cambien la ni al lado contrario para que puedan leer la palabra

I'm 15 years old, and my siter she tooks my phone away like 3 days ago, and the reason is because the bill came really high she paid like 150 dollars just in my phone, and i take care of her kids, everytime that i dont have school and they (kids) dont have either, i have straight As, and she is really nice, oh by the way the bill came up like 80 dollars and this one was on more than 150, do you think she will give me the cell phone back? and if think so when you think she will?

OK im his second top friend in myspace, we talk only in myspace, and we know each other like 3 months ago, and she never get mad at me, even if i did something rude
