She isn't close to one. And I don't know of many libraries that are cool with you videoconferencing with instructors and pair programming 8 hrs/day.
Ultimately, there really isn't anything that can be done - you can't kick someone out because they look or smell a certain way if they're using a public utility the way it was meant to be used.
That "you smell" thing is basically code for "no homeless people." There is no objective smell-o-meter that indicates when someone is actually a threat to public welfare or something. And in settings where people did not know I was homeless, I did not see evidence that I actually smelled bad. They would ask me about my vacation plans while cutting my hair.
There's lots that can be done. How about more computers, for a start? If they're monopolizing 100 computers then how about 1000? Install public showers and laundry facilities, too. Add in a volunteer job training center. Run free programming classes and job interview tutorials. Resumé review classes would be great, too.
Don't do it. Life is all about priorities and keeping your focus. Once you start mixing work and studies, both will suffer.
Go hungry, sell plasma, visit a food bank, do what you have to do. But keep your eye on the prize.
There were certainly periods of time where I didn't see friends much, and my husband had to (gasp) cook dinner once in a while, but it was doable, and I graduated with a 3.7 GPA. I'm not a genius, I certainly did my fair share of procrastination, it was mostly just about making almost every day a "work day" (at least for a few hours), keeping things interesting by alternating between different types of work, and finding creative times/ways to study (commuting, lunch break, doing class busywork watching TV in the evening, etc)
I don't think I would have gotten "more" out of the program by quitting my job and just doing that full time. If anything, the financial stress would have made things more difficult.
How far in the black will a minimum wage job put you month/month? How long will it take to put yourself up on your feet with it?
But why didn't she just go to the public library? An internet cafe? How many hours and how much frustration was endured trying to code on a touchscreen device?
