Can't install on Windows 8
How do I install Ubuntu alongside a pre-installed Windows with UEFI?
How can I play encrypted DVD movies? Often called "He-Who-Must-Not-Be-Named" and "You know who", was it common knowledge at the Ministry of Magic that Voldemort was the same person as Tom Riddle? Here's the information :     There are four different pairs of   opening and closing tags which can be   used in PHP. Two of those, &lt;?php ?&gt;   and &lt;script language="php"&gt; &lt;/script&gt;,   are always available. The other two   are short tags and ASP style tags, and   can be turned on and off from the   php.ini configuration file. As such,   while some people find short tags and   ASP style tags convenient, they are   less portable, and generally not   recommended.   In my experience most servers do have short tags enabled. Typing  &lt;?=   is far more convenient than typing  &lt;?php echo    The programmers convenience is an important factor, so why are they not recommended? What to do with an Ubuntu disk image that appears as a WinRAR file? I am using MiKTeX 2.9 on Windows 7.   I'm getting the error: "can't write on pdf file."  The pdf doesn't reflect what I wrote.  What did I do wrong?  My input:  \documentclass[12pt]{article} \usepackage{epsf} \usepackage{amssymb} \usepackage{graphicx} \usepackage{setspace} \usepackage{amsmath} \usepackage{rotate} \usepackage{endnotes} %\usepackage{harvard} \usepackage{vmargin} \usepackage[nolists,noheads,tablesfirst,nomarkers]{endfloat} \usepackage{natbib} \bibliographystyle{apsr}  \oddsidemargin=1.0in\evensidemargin=0.in \textheight=8.5in\textwidth=6.6 in \baselineskip=18pt \parskip=6pt  \begin{document}  % added, was missing  TEXT  \newpage \baselineskip=12pt \doublespacing  \bibliographystyle{apsa} \bibliography{Dissertation_Proposal}   \end{document} Zero vector of a vector space I know that every vector space needs to contain a zero vector. But all the vector spaces I've seen have the zero vector actually being zero (e.g. $\mathbf{0}=\langle0,0,\ldots,0\rangle$). Can't the "zero vector" not involve zero, as long as it acts as the additive identity? If that's the case then are there any graphical representations of a vector space that does not contain the origin? Simulate Multiple Monitors I'm trying to find out if there is a product out there to simulate Multiple Monitors on one large monitor/tv?  So take a screen and turn it into something like below...  -------------------------------- |               |              | |               |              | |               |              | |               |              | -------------------------------- |               |              | |               |              | |               |              | |               |              | --------------------------------   Something like this...even though in reality it's a single screen.  A software solution is perfectly fine as long as it functions like the built in Windows 8 functionality (Start screen only consumes the screen it was started on/etc).  If anyone is curious as to the reason.  I'm looking to get a treadmill desk since I'm a developer and don't like being sedentary all day.  So the two options that I see are having 4 monitors and mirroring them (I don't want to have to worry about forgetting to move the window that I need) or getting a large monitor/tv and putting it on an arm that I can simply swivel into place.  There are dual-monitor swivel mounts, but they are EXTREMELY pricey and the ones I've found don't appear to have the range of motion that I'm anticipating needing.  EDIT:  I found ... but I can't find the answer to the start menu question (I've sent the company a message on facebook).  Hoping I hear good news as this appears to offer many of the features I'm wanting.  So Fingers crossed there. Easily measure elapsed time XeTeX: What happened to \mathcal and \mathscr? Recently I switched from pdflatex to xelatex to be able to use OpenType fonts. I like to use variables highlighted using \mathcal for specific variables, while I used to use \mathscr-typeset variables for matrices. But when I compile with XeLaTeX they look exaclty the same.  Old code  \documentclass{standalone} \usepackage{mathrsfs} \begin{document} $\mathcal{C} = \mathscr{C}$ \end{document}   Output        New code  \documentclass{standalone} \usepackage{unicode-math} \begin{document} $\mathcal{C} = \mathscr{C}$ \end{document}   Output        Broken code  I tried to get back the glyphs from mathrsfs, but it failed this way.  \documentclass{standalone} \usepackage{unicode-math} \usepackage{mathrsfs} \begin{document} $\mathcal{C} = \mathscr{C}$ \end{document}   Output        Question: How can I get back the behaviour? In principle I'd like to have the old \mathcal letters from the pdflatex-version of Computer/Latin Modern.    Alternate solutions (Addendum 2016/05/11) Launch application on a specific monitor I have Ubuntu 14.04 and two monitors. When I open applications I need some of them to be on the primary monitor and others On the secondary. At the moment, apps always open in the primary monitor.   I have dash icons only on one (left) display, so I can't launch apps using the cursor or active window setting from Compiz. Mathematical journal for an undergraduate I want to make someone a present by subscribing for him to a mathematical journal. (It should appear every month or every two months). The contents should be comprehensible to an undergraduate in mathematics, and be about a broad selection of topics (for example not only analysis).   I expect the content to be something like proposing interesting problems and then giving solutions with some references for further study. Are there some famous journals you could suggest me? Installing 64-bit geoprocessing of ArcGIS for Desktop? I am trying to install 64-bit processing to ArcGIS 10.2, but the ESRI .  One similar question on this exchange  that shows an option to include this, but my setup installation program (which I downloaded) does not show this installation window, but instead goes straight to selecting features to install as shown below.  I can't find any other documentation for running 64-bit geoprocessing on ArcGIS version 10.2.  Can anyone show me how to do this? or is it best to just try to install the service pack 1 version of it? Finite Abelian groups with the same number of elements for all orders are isomorphic Let $A$ and $B$ be finite abelian groups. Suppose that for every natural number $m$, the number of elements of order $m$ in $A$ is equal to the number of elements of order $m$ in $B$. Prove that $A$ and $B$ are isomorphic.  Idea Given that these groups are finite, I think you have to use the primary decomposition theorem somehow. I have a filename in a format like:     system-source-yyyymmdd.dat   I'd like to be able to parse out the different bits of the filename using the "-" as a delimiter. Crookshanks is Hermione's familiar in PoA, GoF, and OOTP. I cannot recall mention of Crookshanks following OOTP, though. What happened to Crookshanks? Does canon refer to Crookshanks in either HBP or DH? Is there any way to get the windows cmd shell to expand wildcard paths? Occasionally, the cmd shell's inability to expand wildcard paths can really be an inconvenience. I had to pass 100 files in a directory to a program, and couldn't type *.ext. Instead, I used mingw's 'ls' to dump the list to a file, then replaced newlines with spaces, copied and pasted into cmd. Quite a nightmare.  I suspect the answer will be no, but has anyone dealt with this or come up with any way to make this easier? Cheese from UHT Milk I live in a town where fresh or whole milk is not readily available. I was wondering if I could make cheese from UHT Milk. If so, what kind of cheese and what method I should use? Or rather, Should I? glBufferData not working outside main function Can a ultracentrifuge be used to test general relativity? With today's ultracentrifuge technology, they can spin so fast that the sample can be subjected to  accelerations of up to 2 millions Gs. That is equivalent to two solar masses. Has someone tried to measure the time dilation in a radioactive sample? How calculate that time dilation respect to the time outside the ultracentrifuge, for example one week. I think that that time dilation will be significant enough to be measured. Magnetic field lines When I searched the net about magnetic field lines,  told something about contour lines and that magnetic materials placed along a magnetic field has some specific loci, which i did not understand. Can someone explain it to me in details.  Also how do we know that tangent to a magnetic field line gives the direction of magnetic field? I am very confused.
