@Ethan because you believe it's the right thing to do? :-) I do TeX coding, helping here, I lead a scout troop and play the organ in a church -- all that for free (or even with expenses)
(please, I'm not showing off, I'm just making an example that there are people who do a lot of things for free)
@StefanKottwitz Here you have a quite cheap Czech hosting provider with English services: isol.cz/?lng=2 (one friend had some good experience with them when he had his own hosting)
@egreg -- the news about the earthquake this morning was terrible. i do hope that the survivors are able to put their lives back together, although the towns they lived in will never be the same again.
@barbarabeeton Yes, very sad. It's not a very populated area, with very old small towns. Amatrice is the place of origin of “spaghetti all'amatriciana”
@JosephWright samcarter suggested to point you to this question of mine which has to do with unexpected behviour of Beamer's \includeonlyframes{}: http://tex.stackexchange.com/questions/325463
Hello, I am sorry, in pgfplotstable, I would like to make one column accept text since I got this error: PGF Math Error: Could not parse input as a floating point... Can somebody tell me what the command to create such a column type is?
TeX considers your usage as ] minus \pi. Remove this ambiguity by using (say) {-\pi}:
\documentclass{article}
\begin{document}
\[
]{-\pi},0[ \qquad -\pi \qquad \int_{-\pi}^0
\]
\end{document}
For more complex interactions, consider using Gustavo's answer. For example, to show membership...
Some manual intervention to provide proper spacing is okay in my opinion. Sure there are better ways of doing the same thing.
@Werner The original answer is just sweeping rubbish under the carpet; the edit is a collection of hacks that make input awkward and the result wrong nonetheless.
@Werner @egerg's perhaps a bit grumpy but it's attacking the wrong thing, the problem is not the -\pi it's the ] you want a \mathopen{]} and a \mathclose{[}
oh no look I agree completely with @egreg, something must be wrong.
@yo' Finnegans Wake is a novel by Irish writer James Joyce. It is significant for its experimental style and reputation as one of the most difficult works of fiction in the English language. The entire book is written in a largely idiosyncratic language, consisting of a mixture of standard English lexical items and neologistic multilingual puns and portmanteau words, which many critics believe were attempts to recreate the experience of sleep and dreams.
