When editing text, I have been using Vim so far. My text documents were either Markdown, reStructuredText or LaTeX. All of them are just source code in some sense, the output format HTML or a PDF in a browser. Single line breaks do not matter in either format, it takes a blank line in between to separate paragraphs. Therefore one has the freedom to insert line breaks within a paragraph at will without it meaning anything semantically.
It is not easy to find a nickname that is well respected in online gaming. It is even harder to find a "logo" that really expresses yourself. After a little survey of cool names I managed to use LaTeX to make the ultimate "H4ck0r" gamer-tag:
LaTeX compilation is quite slow. Especially if some reference changes and the document has to be compiled three times in order to get all the page numbers sorted out. This is bearable as the output of LaTeX is way better than any other text processing system that I have tried.
I first used LaTeX some ten years ago. At the time I was impressed by the quality of the output and handy features like the automatic table of contents. Over the years I learned how to use LaTeX better and also understand why certain things are done a particular way. If one looks carefully enough into the documentation of the LaTeX packages, one often finds explanations which go beyond the how, the authors explain the why as well.
If you are on Debian or any derived distribution like Ubuntu, it is a little harder to find out which Debian package contains your LaTeX package.
For my laboratory reports, I like to write Python programs that do all the calculations and plotting for me. To get the results from the program into my LaTeX document, I use a Python templating system, Jinja.
This is a compilation of classic mistakes that I have seen in many LaTeX documents.
When typesetting physics, there are a couple things that LaTeX does not according to the ISO 80000-2 norm, see TUGboat-18. Here is what I have gathered to implement these conventions.
Since 2007, I use LaTeX. I have used it for documentation, essays and especially for lab reports and other stuff at university. Since around 2011, I know about reStructuredText and use it for most of my documentation, and for a single lab report. My website is also done in reStructuredText, which is very elegant for web content.
