Mars Book 1[edit]

I am having problems saving PDF file. I get invalid annotation error. Using Windows 7, IE 9.0.12 64Bit.


Is this good wikitext?[edit]

Am I correct in assuming that the following is not valid wikitext?


Figure 9.3: Variation of Pressure with Depth
\begin{figure}
\begin{center}
\leavevmode
\epsfxsize=3 cm 
\epsfbox{fig9-2a.eps}\end{center}\end{figure}

I ask because I once reverted an edit on a physics Wikipedia page only to discover that my browser was not configured properly. If the aforementioned text is valid, let me know and I will undo my revert.--Guy vandegrift (discusscontribs) 12:27, 11 June 2015 (UTC)

I found it at Fundamentals_of_Physics/Fluid_Mechanics#Variation_of_Pressure_with_Depth and will hold off the revert till I hear from you reverted the edit.--Guy vandegrift (discusscontribs) 12:30, 11 June 2015 (UTC)--Guy vandegrift (discusscontribs) 18:19, 12 June 2015 (UTC)
@Guy vandegrift: It's LaTeX markup rather than wiki markup, and in this case it seems to be a symptom of the text being copied from somewhere else. I easily found it on the web by googling the first sentence of the section in question. Afaics it's copyvio.
(Looks like in reverting the edit you also undid a couple of typo fixes.) --Pi zero (discusscontribs) 18:32, 12 June 2015 (UTC)
@Pi zero: I reinserted the typo fixes, which should end this conversation, I think. Thanks, \pi_0--Guy vandegrift (discusscontribs) 12:57, 14 June 2015 (UTC)

Status: Rendering process died with non zero code: 1[edit]

I've been trying to make a PDF version of Formal Logic for me to print and read offline, but I got this error. Does anyone know of a solution? Thanks. Kayau (talk · contribs) 18:29, 17 July 2015 (UTC)

@Kayau: It doesn't work indeed − User:Duplode/Collections/Formal Logic fails to render, and excluding pages from the book (hoping that the issue would be caused by some specific page) doesn't help. There seem to be reports of similar issues with all sorts of wiki pages ([1], [2]). In any case, I guess you'd better not bother with the Collection Generator for now − another of the known issues with it is that it can't render tables, which would wreck any Logic book. The one alternative I know of is Dirk Hünninger's offline renderer (usage information, and also installation instructions for Linux; SourceForge download page for the Windows version), which is a behemoth but gets the job done. To use it, you'd create a page transcluding all of the pages in the book (such as e.g. Haskell/Print version) and then run the renderer on that. --Duplode (discusscontribs) 00:02, 18 July 2015 (UTC)
Thanks, I'll try that. Kayau (talk · contribs) 04:14, 20 July 2015 (UTC)
