Until recently, I worked with a rather basic setup of virtual machine hosts. Simply a couple of servers that ran their individual set of VMs. In case of an outage of one of the nodes, all the nodes’ VMs were also affected. That needed change, so I looked at and found ganeti to be something that might help to provide redundancy for the VMs without introducing too much voodoo. Here’s how I migrated the 140 VMs from 17 machines into one cluster.
With our first kid, me and my wife created new photobooks about every 3 months. Once the second kid arrived, we could not make that happen (everyone who has kids will understand …). He is almost 14 months old now, we have not created a single book yet and I am tasked with creating a photobook from the horrible amount of 25 thousand files. And of course, not only did we not create a photobook for a over a year, we also did not create the “good” folders …
One of the things you do as a young parent is to take tons and tons of pictures of your kids. And then, since you cannot and will never look at all of them digitally, but you also don’t want to forget about all those moments you captured, you create photobooks with some of the best of those pictures. Problem is, you don’t really have the time to organize and sort them. Still, doing this quickly becomes very important once you experience how fast things go by, so here’s my “best practice” and some helpers that get me from “a looooot of files” to “a photobook” in a reasonable amount of time.
After having played with xfce window tiling for a while, I came to accept it had some shortcomings which forced me to still place windows using the mouse. It can only place windows left, right, top or bottom of the screen, but not, say, in the upper right corner. This is something QuickTile can and it’s just awesome.
When tasked to do things multiple time, you usually don’t type things multiple times or copy/paste them. Instead, you write a loop which does that for you. Yesterday, I horribly tumbled trying to use one of those loops.
