Stress Test Your Mac with the "Yes" Command

If your Mac is having intermittent problems when it's under a heavy load, you can perform a simple stress test in the terminal to try and reproduce the problem.

All you need to do is run the "yes" command, which will push the CPU until its limit:

yes > /dev/null &

If you have a CPU with multiple cores (which most modern Macs do), you'll have to run it as many times as you have cores. For example, if your CPU has four cores, you'd run:

yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null &

The fans will often kick in so you can see how loud they are, and see if indeed your mac is crashing under a heavy load. Putting this heavy of a load will also help discharge the battery. Just remember to kill the process when done or you'll wonder why your Mac is running so slow.

Command Pi Monitors Your Raspberry Pi from Your Phone 2014

Command Pi Monitors Your Raspberry Pi from Your Phone 2014

iPhone: In case you're searching for a lightweight and simple way to monitor your Raspberry Pi, Command Pi is a utility that allows you to monitor your Pi's reminiscence usage, temperature, and extra proper out of your iPhone.

To use Command Pi, you'll just need to make sure SSH is turned on for your Raspberry Pi, then enter the IP address and login to sync it up. Once that's set up, Command Pi can shutdown the Pi, restart it, or if you're running XBMC, restart that. You'll also see a few stats like CPU usage, memory, temperature, and MHz.

The one screen in the screenshot above is all you get, but it's all surprisingly useful. A few customers report crashing with the app within the iTunes evaluations, but I did not have any issues with it on an iPhone 5s.
