I've been trying to pair up my bluetooth keyboard with my computer after reinstalling from a standard ubuntu 12.04 to a minimal install.  In the minimal install I have no gui, so I've been trying to use the various command line tools available, but I can't figure out how the pairing is supposed to go. Pairing when I had a gui worked flawlessly.  I've asked for help here:   No one has replied but a lot of details of my situation is available there.  How is one supposed to pair bluetooth devices from the command line?
I am developing one site which has chat feature in Rails. I am using Ubuntu 12.04 LTS. I need to check that the site is IE9 because the chat feature using socket io of HTML5. I want to know that how to install IE9 in Ubuntu. I have looked at Chrome and Firefox extensions but if any standalone is available then please give me suggestion.
This was posted on facebook and people are saying it is incorrect, it should be: "...as you and I"   Which is correct? Example images in LaTeX? How to make an example image in LaTeX, a dummy image, a spot holder? I have seen it before, but I can't remember how they would made. It would be nice to be able to use example images - if you should help anyone or you need to question in this community. You might say I could , but I tried - and are obviously too stupid to find anything.  \documentclass[12pt,a4paper]{article} \usepackage[utf8]{inputenc} \usepackage[ngerman, danish]{babel} \usepackage[T1]{fontenc} %\usepackage[]{}  \begin{document}  \iffalse \begin{figure} \includegraphics[scale=1]{•}  \end{figure} \fi  \end{document}   Is it also possible to resize the example image? So I need a usepackage to make an image without including an immage. An placeholder so anyone can try my code without needing images - just needing my tex-code. I hope you understand?  Kind regards! Choosing whether to include PDF or PNG in PDFLaTeX Can I tell graphicx somehow which graphic format to choose when I omit the file extension in includegraphics and both a PDF and a PNG version of the same image exist? The reason is that I have some very large PDF vector graphics (in terms of file size/drawing primitives) that take a pretty long time to load each time I view the document. I would like to convert them to PNGs while working on the document and only use the PDF versions in the final document. Therefore, a global option that I can switch in the end would be great.  An additional plus would be to do the conversion to PNG on the fly during the LaTeX run if there is a PDF that has not been converted to PNG yet, if a tool for that exists. (I know how to use convert, but not how to include it automatically in LaTeX.) Get the size of the screen, current web page and browser window Identifying genes from a list of genes I have a gene list file. Some thing like this      SWT21     SSA1     NRP1     EFB1     TFC3     MDM10   I have another file which also contains the names of these genes in my list along with other essential information about them. The second file looks like this:  chrI    147593  151166  YAL001C -   TFC3 chrI    143706  147531  YAL002W +   VPS8 chrI    142173  143160  YAL003W +   EFB1 chrI    140759  141407  YAL004W +   YAL004W chrI    139502  141431  YAL005C -   SSA1 chrI    137697  138345  YAL007C -   ERP2 chrI    136913  137510  YAL008W +   FUN14 chrI    135853  136633  YAL009W +   SPO7 chrI    134183  135665  YAL010C -   MDM10   I want to extract those lines in the 2nd file which have gene names as are present in first file. I asked a question that has been marked as a duplicate. I read a lot of similar questions and explanations in advance but I couldn't find a solution. In the question that should answer my question the asker used a different (not working) approach. There is even an answer that would work for my case however I'd rather consider it as a workaround than a solution since I have seen examples using my approach.  So I would like your opinion in that case. Would it be ok to repost my question while explaining why other answers didn't help me? I edited my question but I think it's not getting any attention anymore. Naturally I will remove the old question. Is it possible to use a primitive type (int) in as a generic type in Java? Specifically, with a SortedMap&lt;Vector&lt;String&gt;, int&gt; I get "dimensions expected after this (int) token." Help! Is the electromagnetic spectrum discrete? How can I report bugs with or request features for the Stack Exchange mobile apps? jQuery animate backgroundColor I am trying to animate a change in backgroundColor using jQuery on mouseover.  I have checked some example and I seem to have it right, it works with other properties like fontSize, but with backgroundColor I get and "Invalid Property" js error. The element I am working with is a div.  $(".usercontent").mouseover(function() {     $(this).animate({ backgroundColor: "olive" }, "slow"); });   Any ideas? Using sed with special characters Insert data only if record does not exist How to restore a system after accidentally removing all kernels?

NB: This is be no means an exclusive list. It probably effects nearly all Nvidia cards.  Furthermore, this issue has been replicated on a clean install where the only change was a software update and the installation of the latest NVIDIA drivers.
