Caitlin - I'm so glad you are interested in this!
I've worked in a variety of tech related jobs, from doing customer support for AOL dial up (yes, I'm a dinosaur) to working on mid-range computer programming (I was a business analyst, not a programmer), to working in process improvement (CMMI and Six Sigma) and database development, and now I've ended up way over here in Regulatory Compliance which has little to do with technology per se, but I am constantly doing IT development projects, as we use software all the time and need to improve it regularly.
I think, as women, we actually have an advantage in technology.My 'official' background is in technical theatre (I have a B.A. in theatre from a small women's college) and I have an MBA with a concentration in technology management. However, because I am flexible and able to make connections between things in ways that a lot of men are not, I've been promoted and given opportunities that others haven't for that reason.
You don't have to be a coder to work in tech - there are lots and lots of other positions where understanding the way the tech works and how it should be developed are critical and SDLC (software development life cycle) is a whole discipline in itself, and requires no coding, just an understanding of tech. Women are typically better at the human interaction side of software as well - and if you have an artistic or creative side, GUI design is critical to a decent software product.
Don't look at being the only girl in the room as an impediment. You are getting in on the the ground floor of a movement, and there is a lot of chance to learn new things and be the new expert. That's not a bad thing. Also, if you aren't afraid to speak up, it's been studied that women's voices (in terms of the tone of them) are actually more attention-getting in a noisy room. That's why women's voices are so often used for emergency announcements, etc. in public places. Don't be afraid to use your voice!
The other fun perks are being able to get in and out of the ladies room faster (men are often actually lined up to get in the mens room at tech conferences while women breeze in and out, believe it or not), getting preferential treatment when it comes to being stuck crawling under a desk to hook up a monitor, or carrying heavy stuff. I know darn well that I CAN do all those physical things, but it's nice to have an out - and it helps to keep your 'in charge' image intact, believe it or not. I wear skirts and dresses exclusively, am not afraid to use a pretty pen or have feminine accessories, but no one takes me any less seriously because of it. You can still be YOU and be in technology. Enjoy it!
