kSar is one of the best tools to display an easy chart based on your system’s SAR metrics collection. kSar has not been developed since sometime in 2013, and it lacks the ability to parse modern Linux sysstat charts, leaving us with some missing info.

First and foremost – Happy new year! Technically speaking, it has gone rather well so far, this new year. Although it was actually yesterday, I’ve managed to add another feature to my little laptop, and support the Fujitsu Keys on my linux – this time, with no errors, no problems, and without killing SWSUSP2 –…
My brother is a computer illiterate. He can use a computer for the purpose of e-mail messaging and for editing documents, spreadsheets, etc. I have decided to “abuse” his older laptop, an IBM X31 and install Ubuntu on it. This is some sort of an experiment. I wonder how he, a simple user, can cope…
