How to use:
- Take the
download.sh
file and put it into a directory where you want the files to be saved. cd
into the directory and make sure that it has executable permissions (chmod +x download.sh
should do it)- Run
./download.sh
and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.
This is a compiled list of falsehoods programmers tend to believe about working with time.

- There are always 24 hours in a day.
- February is always 28 days long.
- Any 24-hour period will always begin and end in the same day (or week, or month).
