Works that you can show are always lot more impressive than works that you can only talk about. So yes, your projects on GitHub should carry a good amount of weight, or consideration in a recruitment phase, granted that they are relevant to the position or field you are trying to get in, and you are able to explain / answer relevant questions. When it comes to group projects, it is a bit sketchy. But these are great for showing how honest you are. Because, trust me, interviewers are usually good enough to catch you if you try to fool them (if they can't, they're probably from a bad company, and you don't want to get in there anyway).

WTF??? My cron job doesn't run?!$#%

Source: This SO Answer

Here's a checklist guide to debug not running cronjobs:

• Is the Cron daemon running?
  • Run ps ax | grep cron and look for cron.

• Debian: service cron status, if not running, service cron start or service cron restart
