Or you could do what I did, get a shitty minimum-wage code monkey startup job beforehand so you know what you're getting into before you commit, then sock away some funds, take out a personal loan, and because you're a programmer you can turn the entire tuition into a business expense and also deduct the cost of moving to <insert tech hub here>.

Easily paid the loan off once I got my first job. Got a huge tax return last month. Now enjoying writing this from Mountain View.
