Dude, what a day!
TLDR of the first working day: tech stack = hard, math = makes sense. Setting everything up was pretty exhausting, but I'm pretty sure, if I haven't missed anything (too) important, I'm basically close to being ready to do Data Science, woah. Another awesome thing happened - my mom got into the MRI program at a really good school!! Really happy for her. She didn't think it was possible because of how much bureaucratic push back she got on her application (not finishing college in the home country, etc.) but she got in! That's really awesome, hopefully, the program will be worth it.
