I'm a discrete mathematician. My main research interests are discrete optimization and scheduling in specific. I've been using LaTeX on and off since 2007, mostly for homework assignments. I have really gotten into it while writing my thesis though. Scheduling problems call for quite a lot of diagrams, so my main focus and interest within LaTeX is TikZ.

@Jake: Excellent! I'll change the code to reflect this.

comment TikZ: Blurring Effect
Yeah, using opacity directly also changes the opacity of other elements (such as the lines). I tried any kind of combination with nodes, every node, etc. They all appear to occur either after column 12/.style does, or there is some kind of aggregating issue at play. I'll experiment some with transparency groups.

comment TikZ: Blurring Effect
@percusse: I tried that, but it doesn't seem to work. I tried all kinds of combinations, but setting all nodes to some opacity and then then override the last one doesn't work. That is, we don't want to change one column, we want to change all except one.

comment How I could insert an accented word in a new command?
@StephanLehmke: Of course, you are right. So the problem most likely is that the smallcaps font is missing that accented character.

I'm guessing the font you are using doesn't have bold smallcaps ó. Most fonts don't include bold smallcaps at all, let alone accented characters.

@mathematical.coffee: I'll add some explanation to the answer, since there isn't enough room in the comments.

If we were to place the \endgroup after the \def... it would make the \def local to that group and thus not work. If we place the \endgroup before the \lowercase then the lccode assignment would be local and have disappeared before the \lowercase is expanded. As an example consider this: \def\color{red}The color is \color! {\def\color{green}The color is \color! }The color is \color! and study the output to see the consequence of definitions being local.

Excellent point, hadn't thought about that at all. Changed the code to incorporate this.

comment TikZ: Paling Effect
First, loading tikz is enough, it already loads pgf so you don't have to do that explicitly. Second, why are you loading so many libraries? You only need patterns for this example. Finally, does adding opacity=0.1 to the options of the \filldraw you want to affect give the desired result? You can of course play with the value to get different opacity.

I'd recommend TeX By Topic or The TeXbook (That's merely the source, you can probably find it online somewhere or consider purchasing it, it's a nice book to have). Both treat the ## construct.

comment TikZ borders showing through when they shouldn't (overlapping circles)
@Uly: I'm sure. zoomed in to 6400% on reader. Also tried it on kpdf (yes I know, it's old) and I don't see any edge there either.

This doesn't happen for me on Acrobat Reader 9. What viewer are you using? On a side note, TikZ already loads xcolor so there is no need to do so yourself separately.

comment Whole page table with tabularx
@egreg: I'll change the code. I am still curious about this though. From what I understand, \centering places it's argument in a \hbox to\hsize with \hss on either side to center it. Would that not force it to be in restricted horizontal mode?
