From time to time I have to read some json data from a file and use it in python. It’s not too often, but everytime I have to take a look at a python script where I already have done it. Maybe with this blog post I can remember that two lines from now on
These days I started with my first steps into Docker. We are using it at the company I work for and also for some private stuff, I thought it is a good idea to have a fast solution for testing. After I installed all necessary components (Docker version 1.11.2) the docker-daemon was not able to start.
After an upgrade to mongoDB 3.X and the switch from the DB-engine mmapv1 to wiredTiger we had to resync all replica sets from scratch. During that resync I figured out, that there is just on one shard a small collection which has a very large number of documents which are created, updated and deleted. Pretty close to that point, the resync should be done, the log file explodes and the sync crashes.
