Screenshots In KDE Plasma

October 27, 2016 at 07:30 PM    
 

I have been an avid user of the KDE Desktop for over 12 years. Some things about the new Plasma desktop are not immediately obvious.

Overall the new Plasma desktop is fantastic. In some cases, the usual tools are missing. KSnapshot, the screen shot utility, is one of those tools. There are a few different projects that I checked out as a replacement, but I landed on using Spectacle - https://github.com/KDE/spectacle. While I think this is getting rolled into Plasma eventually, for now you may have to install it separately. Most distros have a community package available.


Cheers,
Brian

This clip from Last Week Tonight with John Oliver is a really great overview of the pros and cons of the encryption debate. Hilarious too!

Elevator Logic

Whenever I am in a building with multiple elevators, I ponder the logic and programming behind how the elevators respond to calls and if it is optimal or not. This simulator is a great way to geek out on this for real...er simulated, at least

This doesn't surprise me, I've often wondered why Varnish is so popular when there are better and sometimes even easier solutions out there.

IBM Research Report: An Updated Performance Comparison of Virtual Machines and Linux Containers

[PDF] Interesting research report from IBM comparing performance of docker vs KVM. I would have liked to see Xen instead of KVM. Obviously full virtualization has more overhead than containers, but there are decent trade offs to this in terms of flexibility and security. Docker is getting to be quite flexible though, and has some benefits. I don't know that performance will be the key criteria for picking a side (Containers vs. Virtualization)
