Motivation:

I feel more motivated and competitive when I see my friends are also doing CP on Codeforces. But it's hard to check who is online or when they were online by going to each of my friend's profile. So I've written this userscript to show the last online status of my friends in the table in the My friends page.

Result:

Usage

• Install any "Monkey" extension. I prefer Tampermonkey.
• Tampermonkey for Firefox
• Tampermonkey for Chrome
• Click on this link: GreasyFork
• Click "Install". Confirm installing the script.
• Now go to My Friends and your table should be updated with a new Last Online column.

This userscript uses the Codeforces API to retrieve the last online time for each username in the friends list, and then calculates the elapsed time in years, months, weeks, days, and hours. As it repeats this process for every username in the friends list, there is some delay (~1 sec). I'm not quite sure how to fix that. If you have some ideas regarding this please feel free to share them with me. Also, please share your thoughts on this script. I'm interested in hearing your perspective.
