Ask HN: How did you write code on restricted hardware?
2 by diselody | 2 comments on Hacker News.
I remember trying to write code for a project in college from those library computers when I did not have a laptop of my own at the time. I often used sites like Codepen and copy-pasted the progress into a github repo so I didnt lose my work. What are some workarounds you’ve used (or tried) for writing or running code from restricted hardware, like a school computer or a mobile device? What kind of project was it for, and what hurdles did you encounter?
