Use this trick to bulk delete your old repos or old forks

(Inspired by https://medium.com/@icanhazedit/clean-up-unused-github-rpositories-c2549294ee45#.3hwv4nxv5)

1. Open in a new tab all to-be-deleted github repositores (Use the mouse’s middle click or Ctrl + Click) https://github.com/username?tab=repositories

2. Use one tab https://chrome.google.com/webstore/detail/onetab/chphlpgkkbolifaimnlloiipkdnihall to shorten them to a list.

3. Save that list to some path

4. The list should be in the form of “ur_username\repo_name” per line. Use regex search (Sublime text could help). Search for ' |.*' and replace by empty.

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}
