Installing VMWare vSphere Hypervisor on Server with additional RAID Controller

The first step was to configure the RAID on RAID 1 level, then the ESXi iso had to be installed on the Harddrive. The problem was, that the standard iso of VMWare vShpere Hypervisor does not include the required drivers for the RAID controller, and because the controller was fresh on the market, there was no custom iso available for this controller at that point of time.

See changes that were made by user in latex document

The core problem is to compare two latex generated documents and highlight differences between them. The important part here is that a simple *.tex document may have dependencies to other documents or included .tex files (i.e. each chapter/section may be stored as a separate file). Therefore, one needs to find a way to first combine and build both projects (i.e. produce output), then compare them and then produce a single pdf file that highlights differences.

Starting multiple docker containers and let them communicate

When developing microservice-like architectures it is reasonable to assume that docker is used for deploying the individual services. In order to test if the services worke together properly, especially on a small scale, on can start a docker container for each service. Since each of the services gets its own network stack created by docker, they can by default not communicate with each other. It would be nice to have the possiblity to simply start all services at once and give them the possibility to communicate with each other using the hostnames of the services.

Unable to edit git commit message with newly installed git

Git allows the user to provied commit messages either via a command line argument or by opening a text editor with a commit message file that the user can freely edit. The obvious benefit of the latter is that one can use all the functionality of the chosen text editor and it is in general easier to write proper commit messages than when simply supplying the message via a command line argument. When freshly installing git on a linux system, the git command line client assumes that the vi text editor is installed and will try to use it to let users edit the commit messages.
