ScrollViewer's Viewport Height VS Actual Height
WPF DataGrid : CanContentScroll property causing odd behavior
How to generate PDF/A and PDF/X? I have heard about PDF  PDF/A (for archival) and PDF/X (for printing). How to generate LaTeX documents like that?  I'm also interested in answers with plain TeX and ConTeXt, and hopefully with both pdfTeX and XeTeX engines. Why does Gandhi want to nuke me? Different civilizations obviously have different priorities. For example, Gandhi always seems to rush nuke technology and the Mongols will most likely start invading and spread like mad. Are these variables public knowledge? Can you tell by who you are playing what strategy they will adopt during the game? Is my model any good, based on the diagnostic metric ($R^2$/ AUC/ accuracy/ RMSE etc.) value? What are valid values for "data defined" labeling settings? I'm using QGIS 1.8. I'd like to customize label features on an existing shapefile using the new label engine and it's "data defined settings" option. I'd like to know what the attribute table field types should be for each of the settings: All 7 font options, all 2 buffer options, and all 6 position options. Should they all be numeric fields, or some text, or both? I want to create these fields in the attribute table correctly so that I can map them to the label field settings. I can't find information on the proper field types anywhere. Thanks for your thoughts. How do I reset my Unity configuration? I've been messing around with Unity and broke something, how do I "start over"? I'm a little confused about the following sentences. Could you please tell me which one(s) is/are correct?        The first and the second chapter are difficult.   The first and the second chapters are difficult.   The first and second chapters are difficult.   The first and second chapter are difficult.      I believe #1 &amp; #3 are correct, while #2 &amp; #4 are incorrect.  But when seeing the answers to the Quora question , I wonder why they say #2 is correct. Problem:  Start page numbers from chapter one and also reflect this in the TOC.  Currently the code for TOC is:  \renewcommand{\contentsname}{Table of contents}  \setcounter{secnumdepth}{2} \setcounter{tocdepth}{2} \tableofcontents   I would appreciate if I can be pointed in the right direction. So far I have understood that you can use \chapter* in order not to include a chapter in the TOC.  Questions:  1) How would you force Latex to start numbering from chapter 1 and forward?  2) How can you start page numbering from the first chapter? Missing abstract with amsart class I'm not very good at LaTeX but I've been using it to write my dissertation. Have just come to the end and trying to format everything correctly. Whenever I try to put my Abstract paragraph into the form \begin{abstract} (writing here) \end{abstract} and click play the whole abstract section just disappears. What am I doing wrong?  \documentclass[12pt]{amsart}  \begin{document}  \begin{abstract} (my abstract here) \end{abstract} \end{document} wrong positioning of figure with tabular in xelatex I recently updated MikTex and it seems Xelatex is not able to place figures correctly anymore. Before updating all figures were shown correctly. I work with Texworks and Miktex 2.9  Here it is the code that I run:  \documentclass[10pt,a4paper]{report} \usepackage{graphicx} \graphicspath{{method1/}{method2/}{dpfig/}}  \begin{document}  \begin{figure}[!htbp] \centering \begin{tabular}{cc} \includegraphics[trim=6cm 2.5cm 6cm 2.5cm,clip=true,width=0.33\textwidth]{figure1.eps}&amp; \includegraphics[trim=6cm 2.5cm 6cm 2.5cm,clip=true,width=0.33\textwidth]{figure2.eps}\\ \end{tabular} \caption{Two figures} \end{figure} \end{document} \end{figure}   With this code, figures are correctly trimmed and the relative position between figure 1 and figure 2 is maintained. However, the position in the document is wrong: figure are placed upper and more right than expected (as the bottom-left corner of the table was placed in the middle of the page). The unusual thing is that this does not happen in draft mode and picture are shown centered as it would be.  I usually compile with Xelatex, Makeindex and Bibtex.  I hope to have been clear.. bye!  EDIT: Sorry, I forgot to add the images I prepared from the file that run that script: How to hide "Share", "Copy Link", "Copy to" buttons in my site? I'm using SharePoint Online modern UI.  And, I want to hide Quick edit, Sync, Export to Excel, PowerApps, Automate, Share, Copy Link, Copy to from my site.  Please check below picture.     I found the easy solution about PowerApps, Automate, Sync buttons in below URLs.        But I can't find solution other buttons. I don't want to use SPFX if possible, but is there no choice to use SPFX? Prove $\limsup\limits_{n \to \infty} (a_n+b_n) \le \limsup\limits_{n \to \infty} a_n + \limsup\limits_{n \to \infty} b_n$ I am stuck with the following problem.     Prove that $$\limsup_{n \to \infty} (a_n+b_n) \le \limsup_{n \to \infty} a_n + \limsup_{n \to \infty} b_n$$   I was thinking of using the triangle inequality saying $$|a_n + b_n| \le |a_n| + |b_n|$$ but the problem is not about absolute values of the sequence.  Intuitively it's clear that this is true because $a_n$ and $b_n$ can "reduce each others magnitude" if they have opposite signs, but I cannot express that algebraically...  Can someone help me out ? Metric on Cartesian Product I'm currently stuck on an exercise where I need to show that if $(M,d)$ and $(N,\rho)$ are metric spaces, then $d_2((a,x),(b,y)) := \sqrt{d(a,b)^2 + \rho(x,y)^2}$ defines a metric on $M\times N$. I've already shown that the basic criteria of a metric are met, but I still need to show that the triangle ineqaulity holds.  I've tried using the triangle inequality on $d$ and $\rho$ and estimating the square root with $\sqrt{a^2+b^2}\leq a+b$, but regardless of which order I've used them in, I seem to overestimate my target. I thought maybe I somehow need to use Cauchy-Schwarz, but I don't know how. Possible (but not serious) glitch in close/reopen I just had one of my questions closed. (Hey - it happens to everyone) When I clicked on reopen - lo and behold - it worked. I cast a reopen vote!  Is this a glitch? I know we need 4 more votes anyway but still...  And no  tag please :) Prove that $\lim_{n\to\infty}a_n\le \lim_{n\to\infty}b_n$ How to initialize HashSet values by construction? Matrix is conjugate to its own transpose Mariano mentioned somewhere that everyone should prove once in their life that every matrix is conjugate to its transpose.  I spent quite a bit of time on it now, and still could not prove it. At the risk of devaluing myself, might I ask someone else to show me a proof? I'm programming a presentation in LaTeX using the beamer class.  However, it defaults to 4:3 aspect ratio slides, while everything I use is 16:9. Is there an easy way to change this using a command or two? calling main() in main() in c "You just can't" vs. "you can't just " I'm a bit confused about this. Which expression is correct?     You can't just do that.    or      You just can't do that.   I'm trying to say:     You can't just bash an ideology because of what someone has said/done. Accessing the index in 'for' loops?
