Sharpening photos with gimp

I find quite confusing the fact that the most powerful tool for image sharpening is called unsharpen mask. This is so for historical reasons so we need to live with it. The tool options functionality is also a bit confusing. The manual does a good job in explaining it (https://docs.gimp.org/en/plug-in-unsharp-mask.html)

Spectre 2015

Watched the latest James bond film yesterday. Not a bad film although it is a bit predictable. It follows the particular pattern of James bond films

Adding a list of numbers in linux command line

Lets say, that you want to see how much space a specific set of files take in the disk. You need to add their sizes. How do you do that using command line?
Easy: ls -l *052015|awk '{s+=$5}END { print s}'

This will sum the size of backups made in May 2015 and return the total. Neat eh?

Archmage

The last book of the Drizzt series (The forgotten realms). Coming after the Iron dwarf it continues the story of the companion of the halls, trying to take Gauntlgrym back. It is a nice, easy reading, not too complicated, with a few nice twists here and there.
