Last night I got a lawn mower as a present given to myself. I have never had one before and I felt like having one. I must say it is fantastic and really really fast. I could only try it for half an hour or so but I am very happy.
The problem is that there is not a lot of grass since we are in the middle of the rain season (April) but the grass is starting to grow fast now.
One of the truly impressive tools I discovered this week is cpulimit. It allows you to limit how much cpu percentage a process can use. It is specially indicated when running cpu intensive applications. In my case it is 'ffmpeg'.
I use 'ffmpeg' on a daily basis to convert my .avi videos to .mp4. I often run the script at night with cron.daily but the problem arises when I need to run it during the day. Here comes cpulimit to the rescue:
$ cpulimit -e ffmpeg -l 800 -b
Here is a quick explanation:
-e ffmpeg (the process to limit)
-l 800 (I have 16 cores: 800 = 50%)
-b Run cpulimit in the background to free the terminal
