Minecraft Overviewer

Minecraft Overviewer

Just some instructions to remind myself how I got the Minecraft Overviewer working on CentOS.

Now create a config file to tell Overviewer where the assets (texture images etc) are:

Then run Overviewer telling it the location of your config file:

After some time the overviewer map should be created. The… Read more »

Gitlab API Command Line Access

There appears to be a few methods for managing a Gitlab installation from the command line. I liked python-gitlab and I installed it onto Linux Mint/Ubuntu as follows:

Restoring a Gitlab Bundle

I had an odd request today from a guy who had deleted his GitLab project and his local repos. I had been making backups using:
