The other day while troubleshooting an issue on a server I noticed something I hadn’t ever noticed before which was an exclamation mark next to the uptime output from the htop command. After investigating and looking over the source I found that it is a bonus letting you know that your server has been up for a long time. Basically anything over 100 days of uptime will produce an exclamation mark next to the uptime reading. Below I show the sourcecode from the UptimeMeter.c file in the htop source as well as examples of how the htop uptime can vary depending on how long your server has actually been up.
I am fairly new to Markdown which is a lightweight markup language. I have really just started becoming more familiar with Markdown while posting or replying to articles in the Question Defense Engage section. Markdown is the markup language used on Engage to format the posted questions, posted responses, comments, and pretty much anywhere that content data is entered. So far I really like Markdown and have been impressed with how user friendly it becomes as you learn the Markdown tricks as I call them including asterisks or underscores for bolding or italicizing, brackets for links/URLs, and numbered lists simply using 1., 2., 3., etc. While the Markdown learning curve has been fairly steep for me the more I use it the more Markdown is sticking with me.
