Here is a selection of my answers at Stackoverlow that I consider relevant because of various criteria. They can contain important information or serve as a reference to frequent questions or reflect significant effort that I put into them. Trivial answers to trivial questions are not considered here. You can find all my answers on Stackoverflow.
Each entry in this list contains the title of the question with a link to my answer, tags of the question as they are in Stackoverflow, my additional tags and potentially a link to the associated source code ("snippet"). I generated the list using the Stackoverflow API and adapted it to my purposes manually.
I maintain a similar list with my relevant answers on math.stackexchange.
