A word about tags, or categories as wordpress seems to prefer to call them.
I will try to limit most posts to one specific issue and categorise them accordingly. So a post about networking will be categorised under “network”. I will also list issues that I have not resolved yet, and they will also include the category “unresolved”. A bit like a to do list. Hopefully these posts will all be resolved over time. When that is the case, I will edit the post and include a link to the post that contains the solution.
