Best Major for success in the field of technology?

No degree qualifies you for a job to do anything, frankly. Whether you have a degree, training through a place like Treehouse, or have learned things on your own, you have to be able to show what you've done or can do, and can speak and write intelligently about the same. This path varies for everyone, and it all comes down to how passionate you are about learning this stuff, and how best you find you learn it (self-guided or academic or through projects....).

That being said, a degree in Computer Science is probably the best fit if you want to pursue programming in your school, but it absolutely depends on the university and how current their curriculum is, what resources they use, and so on.

Jeremy,

For me, the relatively new discipline in Informatics was the best choice. I have an accounting degree and realized after working in industry for a few years that there is a huge demand for people who know technology who also have business sense. Too often IT departments do not know how to effectively communicate with the business side of things and vice versa. For professionals who have both skills, there are myriad opportunities with no ceilings and this trend is likely to continue.

Taking business courses or even minoring in business might be a good idea for you. My two cents.

For me it depends on what you want to do and what kind of person you are.

You are pretty lucky to have resources like Treehouse at this stage in your life because when I was college age there wasn't even any internet so learning options were very limited.

If I was to have my time again, I would be looking at doing a classic subject like maths or maybe something like business. You can pick up the technical things on resources like Treehouse and if you can show an employer that you are self-directed in your approach to learning then this will appeal to them. Also, a mix of business and technical skills will be very useful as mentioned before.
