comment Trouble labeling an angle within a picture
I can't tell you exactly because you've not provided the code required to reproduce the problem. I assume you are loading babel with a language and using active short hands, presumably including the ". The TikZ library works around the problems this otherwise causes.

comment Trouble labeling an angle within a picture
Does precisely the code you posted give an error when you copy-paste it into a new, empty .tex file and compile? I'm betting not. We need an example we can reproduce the issue with. However, as a guess: in your real document (which does give the error), try adding babel to the list of TikZ libraries you are loading.

comment how to hatch a cell in table
You are also loading packages multiple times, packages you don't need (with 99.9999999999999999% probability) and packages in the wrong order. Expect things to break in strange ways.

Put a grid over the form to find the coordinates, if you aren't already doing so.

comment PDF form as background image - filling the form fields
Obviously easiest would be to integrate the answers into the source of the form and compile it. But if you are stuck with the form-as-background-image paradigm, perfectionism is misplaced, I would think.

comment Is the philosophy of LaTeX actually realized in practice?
Well, people don't tend to post questions when they're busy writing content. At least, they don't tend to post questions here. So surely you must appreciate a certain selection bias in your sampling strategy? If you are writing a paper, say, and don't know where it will end up, the key thing is to stick to a standard class (article) and stick with the default format. Don't load any packages you can possibly do without. Don't change the format or font more than you absolutely must. Then it will be easier by far to adapt to whichever specific format you need later.

comment What is a good environment for writing problems and solutions?
Please provide a minimal working example (MWE) which demonstrates your situation and what you have tried. It matters a very great deal which class you are using, for example, and what a typical problem/solution pair looks like in terms of content, length etc.

Aren't transitions usually a matter for the PDF viewer? Different viewers support different kinds of transitions.

comment zoom in on a portion of a table in beamer
The linked question concerns zooming in on an image, but it just happens to be an image. It isn't doing anything with the image to get the zoom. Essentially, your question is exactly the same: how to zoom on part of a slide, regardless of content. (As opposed, say, to the use of the spy library, which would only work straightforwardly for certain kinds of pictures.)

comment zoom in on a portion of a table in beamer
Have you read the section on anticipated zooming in the manual? If you continue to have trouble, please include a minimal working example in your question. (Very nearly almost) All questions should include an MWE, as you presumably know by now.

comment Is the philosophy of LaTeX actually realized in practice?
As a whole, the question asks for opinions. The very last part might be answered objectively, but that is only one question among others here (violating the one-question-per-question idea) and is itself too broad. This part of the question, in particular, also seems designed to inflame and is something of a rant. I understand that you may find LaTeX frustrating, but venting that frustration does not make for an answerable, on-topic question. And marking it off-topic does not make it bad. It just marks it off-topic for this site. Good questions can be unsuitable for the Q&A format itself.

@GustavoMezzetti Seconded.

comment Is it a good habit to use a colon in the description list?
This is off-topic here. It belongs, maybe, on English Language & Usage or the typography site. It has nothing to do with TeX. It is about how something should look and not how to make it look like that. However, for what it is worth: it is definitely wrong to have a space before the colon. There is an issue with writing Cat: This is a cat. The capitalisation of T is not correct (except in a book title, for example). That said, anything in a list is already in a kind of informal note-like format so the rules of standard English punctuation don't straightforwardly apply.

comment pdflatex long file name error: I can't find file
A piece of advice: you're using Linux? Great. Install detox and run all files through that. It will zap through directories of dubious file names in no time. The results will sometimes be awkward-looking, but they will be safe. Can be customised as required.

comment pdflatex long file name error: I can't find file
It depends. To be safe and since you've not given any indication whatsoever of your code so we don't know how you are using the file names: avoid any strange characters. Strange characters include brackets of all descriptions, spaces, possibly underscores, non-ASCII characters, punctuation marks (hyphens are safe, a dot precedes the file extension). If you stick to English alphabet letters, Arabic numerals and hyphens, excepting the dot preceding the extension, you should be reasonably safe.

@GustavoMezzetti But shouldn't it be safe to use center within a minipage?

Please provide a complete example we can copy-paste and compile rather than a mere code fragment. Complete minimal examples are much more useful.
