I was pretty hyped to come to Stack Overflow and I want to contribute and talk about coding on my . But... I have been pretty discouraged here.  I can't ask questions where I want to. I can't answer easy questions I know the answer to.  I'm afraid to ask questions because it looks like everything just gets downvoted or deleted. I don't have this problem anywhere else, like Reddit. Is it worth it to try to keep going here? I'm pretty bummed out about the experience here.
I am new to Stack  Exchange and I think it's very impressive.  One thing bothers me is that because it is so far down the line, I don't think beginners stand a chance of growing.  As time goes on, more and more questions are being answered and therefore if someone asks something with a really basic answer you can just comment. However, beginners can't comment until they have a reputation of 50. The only way they can build up is by answering questions. But if they answer a basic question long winded, they will be voted down because not so much effort was needed or because its already a duplicate and will lose the bit of reputation they have earned.  Can you tell me the future for beginners?
Suppose I define a new theorem "Theorem" and declare that its counter should be reset whenever the subsection counter is incremented or reset:  \newtheorem{theorem}{Theorem}[subsection]   At some point in my (article) document I start a new \section (say, section 2) without starting a \subsection. I expect the first theorem in this section to be numbered with "2.0.1" (which may be considered bad style). However, the theorem is numbered "2.0.2".  Is this "by design" (technically, I didn't start a new \subsection) or a bug? Moreover, what would be a proper workaround? (Such a workaround should not involve manually resetting the theorem counter, and it should work for whatever theorem type I may define in addition to "Theorem".)  \documentclass{article}  \newtheorem{theorem}{Theorem}[subsection]  \begin{document}  \section{bla}  \subsection{blubb}  \begin{theorem} Some text. \end{theorem}  \subsection{foo}  \begin{theorem} Some text. \end{theorem}  \section{bar}  \begin{theorem} Some text. \end{theorem}  \end{document}   EDIT: In response to Seamus' comment: The unexpected counter value also occurs with amsthm and ntheorem. I have to resit a calculus exam and for some reason set proofs were never my best friend...  Anyway, on a practice exam I encountered the following proof:  $$A\cap(B\cup C) = (A\cap B)\cup(A\cap C)$$  When I draw a Venn-diagram it seems quite obvious but I couldn't manage to write the proof down properly.  If someone could help me, that'd be great! Story with VR worlds for the wealthy Why do some font commands behave differently? I've always been confused by the differences in behavior of font commands.  For example, we have \mathrm{} and \texttt{}, which can be used like this: \texttt{hello} world.  And then we have \it and \bf which must be used as {\it hello} world. If one uses \it{hello} world, both words are italicized.  Internally, what is the difference here? And was this difference a conscious design decision?

But, only by using explicit HTML. Since I think creating a link to documentation within a code block is a fairly common use case, it should be possible to do this using the GUI.   I should be able to highlight some code. Press the  code formatting button. Then highlight some code within that and press the link button and create a link.  Today this results in:  [parseInt][3]("01", 10);   it should result in:  ("01",10); Movie with humans battling aliens piloting giant animalistic, water-walking robots or sea warships I have memories of watching it a few years ago (I was a kid then) in the early 2000s probably; before 2010 I think. It was a movie with giant robots, and the enemies were aliens piloting what I remember as giant, more animalistic robots. I remember those animalistic ones running on water. The aliens themselves were a little taller than humans but mostly humanoid. I remember what the aliens look like a bit; most of the movie they were clad in some kind of armor, but the scene I mentioned showed one's face, if I remember well, grey skin, vividly green eyes, a beard made of some kind of quills, bald. I have this one scene that stayed crystal clear in my memories. The heroes had captured an injured alien, and other aliens attack to, in the end, just retrieve the injured one, leaving with this one without attacking further this time. I also remember the aliens going through a city in some machine (I'm actually not sure this one was piloted though) and destroying anything it perceived as a threat, from cars to security cameras. My memories are coming from years ago, so I might be wrong in a bunch of things there, but this one scene, I can assure is correct. This might remind a bit of Pacific Rim, but it isn't. (It's watching Pacific Rim that reminded me of this movie.) It doesn't seem to show up on any giant robot movie list on internet, weirdly, so I hope you can help me. And now I'm starting to wonder if there was really robots on the heroes' side. Maybe it was warships (sea ones, not spaceships). As I said it was some time ago and I was young, so bad memories are likely. I'm trying to rotate the blades of a windmill for an animation but the windmill is already at an angle. When I keyframe it on it's own axis (after pressing control + alt + space) and rotate it the blades spin inwards during the animation before coming back at the end. I've tried locking the other axis but that keeps the blades from rotating back to the right orientation. Also, whenever I rotate the object 360 degrees it turns the 360 into a really small number (0.0001) so it plays forward hallway then backwards (with a 180 degree keyframe halfway). Any help would be appreciated!. Boxplot interpretation: is it correct that a boxplot is missing a whisker? I have a data set that has customerID and daily visits. This dataset records the number of times customers visited the site in a day.   customerID   TotalVisits  1            6  2            17  3            20  4            25   Just to explore the data further, I tried plotting the TotalVisits values in a box plot. The plot doesn't seem to have a lower whisker. q1=1 and there are no values between q1 and  q1-1.5(IQR). The plot has q1, q2 and q3. The minimum value and q1 are the same.   Is this why the boxplot doesn't have the lower whisker? Could you please help me with the interpretation? Is it correct to draw a boxplot without any whiskers?

When I compile the following code, I get the error message Sorry, the system call pdflatex ... did NOT result in a usable file.  In order to make my code work, I first need to remove the includepdf statement, compile (to create the externalized figures) and then compile again with the includepdf statement.  I suppose that it is a bug, or is there any possibility to solve it ?  Of course, the file test.pdf is totally independent from the externalized pictures from pgfplots.  \documentclass{scrbook}   \usepackage{pgfplots}  \pgfplotsset{compat=1.8}  \usepgfplotslibrary[external]  \tikzexternalize[shell escape=-enable-write18]  \usepackage{pdfpages}   \begin{document} \includepdf{report_test-figure44}   \begin{tikzpicture}  \begin{axis}[  xlabel=Cost, ylabel=Error]  \addplot[color=red,mark=x] coordinates {  (2,-2.8559703) (3,-3.5301677) }; \end{axis}  \end{tikzpicture}   \end{document} Why is pressure in a liquid the same in all directions? I'd like answers both in the more intuitive side an on the more precise side.   Thinking of water as "cubes" of water, for example, would allow pressure in the z axis to be independent of the y or x axis. Choosing other "shapes", like a  triangular prism, yield different results. Will this fact, then, be dependent on the format of the molecules of the liquid ?  I've heard of the rotational symmetry of liquids. What is its precise statement ? Why is it true ? Should the weight of downvotes be increased?
