I'm writing a realively normal document. I just adjusted it to print it double sided. Now a few pages have weird placement of text and images. Notice that the text should be directly under the section header and the image directly below it.   The source for the page:  \subsection{Cartridge} The newly designed cartridge is half the height of proof of concept's cartridge while holding the same amount of plastic tube. The force needed to pull the plastic out of the cartridge is the same, as described in chapter \ref{subsec:des2_cart}. The difference between size is shown in figure \ref{fig:cartimprove}. The cartridge does not damage the plastic bag. The cartridge is found to be easy to replace thanks to the sliding the mechanism, although it is advised to test this mechanism with other test subjects. It should, however, be noted that there is quite some space needed between to cartridge and the sealer mechanism to get the cartridge out. This space is needed because the opening between the seal beams is too small for the cartridge to pass through. So to get the cartridge out you will need to tilt it quite a bit. Figure \ref{fig:carttilt} visualizes this.\\  \begin{figure}[H]     \begin{center}         \includegraphics[width=0.8\textwidth]{img/cartimprove.PNG}         \caption{Size reduction of new cartridge}         \label{fig:cartimprove}     \end{center} \end{figure}   and my preamble:  \documentclass[12pt, twoside, openright, titlepage]{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \renewcommand{\familydefault}{\sfdefault}   \usepackage[margin=2cm, twoside]{geometry} \usepackage{amsfonts, amsmath, amssymb} \usepackage[none]{hyphenat} \usepackage{fancyhdr} \pagestyle{fancy} \usepackage{float}  \usepackage{multicol}  \usepackage{siunitx}  \usepackage{pdfpages} \usepackage{pdflscape}  % References % \usepackage{hyperref} \usepackage[ backend=biber, citestyle=numeric, sorting=none, hyperref=true ]{biblatex} \addbibresource{ref.bib}  % Images %  \usepackage{graphicx} \usepackage{caption} \usepackage{subcaption} \usepackage{wrapfig}  % pro and cons lists* \newcommand*\MyPitem{% \item[\textbf{\color{green}\scalebox{1}{+}}]} \newcommand*\MyCitem{% \item[\textbf{\color{red}\scalebox{1.1}{-}}]}  % Page layout%  \fancyhead{} \fancyfoot{} \fancyhead[RO, LE]{\slshape title} \fancyhead[LO, RE]{\slshape name} \fancyfoot[LE, RO]{\thepage} \renewcommand{\footrulewidth}{0pt}  \parindent 0ex \usepackage{tikz,amsmath, amssymb,bm,color} \usetikzlibrary{calc,patterns,decorations.pathmorphing,decorations.markings,shapes,arrows} % needed for BB \usetikzlibrary{calc}  \begin{document} \includepdf[fitpaper=false, pages=-, noautoscale=true]{inc/frontpage.pdf}  \cleardoublepage
I'm writing a latex document which contains a table. This table is doesn't fit the actual page so it's placed in the next page.  The problem is that vertical spaces are added automatically in the previous page in order to fill the page and I want to avoid that from happening.  I use H in order to add the table figure.
How can energy be useful when it is 'abstract'? The topic which haunted me for two years until I gave up on it. But now I am doing engineering and this topic suddenly popped out of my textbook from nowhere. I seriously need to understand this topic because I wasn't able to do so in the past. I have read many book on 'energy' and it came to nothing. Maybe just because the many books I have read all said 'energy' is something which doesn't 'exist'! It is 'abstract'! It is just a number which represents the state or orientation of a system. But then I see so many examples that 'uses' energy to do 'work'. But the question here is that if anything doesn't exist in this universe, then how can the same thing be used to do something that exist?  My problem is that I didn't understood the topic 'energy' and all the other topics related to it (work, power etc.) I have got myself a dxf which is built with units in the wrong scale. How do I upscale that in QGIS?   Note it does open in QGIS, just in the wrong map units and location. I have an email account that has passed 60GB of emails, and currently I'm having a lot of trouble using an email client to archive emails of last year (2011).  Via terminal, I am trying to use  to locate the files between 2011-01-01 and 2011-12-31, but no avail.  How can I find files between two dates?  If relevant, the end goal will be a batch that will move each file found, matching the date interval, to a folder. Why isn't my Minecraft LAN server working? My LAN server won't let my cousin join me or me join my cousin. It won't show up on the multiplayer screen - it keeps saying "scanning for LAN servers" but it never finds it. I am at his house and we use different computers but it won't connect. How can I fix this? Is $\frac{\textrm{d}y}{\textrm{d}x}$ not a ratio? In the book Thomas's Calculus (11th edition) it is mentioned (Section 3.8 pg 225) that the derivative $dy/dx$ is not a ratio. Couldn't it be interpreted as a ratio, because according to the formula $dy = f'(x)dx$ we are able to plug in values for $dx$ and calculate a $dy$ (differential). Then if we rearrange we get $dy/dx$ which could be seen as a ratio.   I wonder if the author says this because $dx$ is an independent variable, and $dy$ is a dependent variable, for $dy/dx$ to be a ratio both variables need to be independent.. maybe? What is CTAN.org now? Console freezes on auto-complete of /mnt/folder (CIFS) share I have a Ubuntu 14.04 server that will lock up after an undetermined amount of time when you attempt to tab-auto-complete the path of a CIFS share in the /mnt directory. I mount the share and it seems to work fine for a uncertain amount of time. I can do ls or run du on folders within the mounted share. Then I will go to tab out a folder path and my console locks up. I can start a new session but it will lock as soon as I try to mess with the mounted share; this even happens to other users if I have them try as well. I have no idea why this is happening? I've never seen this issue. Bibtex style for "Statistics and Computing" I would like to create a bibtex style which answers the requirements of Statistics and Computing journal. How could I do that? Here is an example of how the bibliography should look like:  Journal article: Hamburger, C.: Quasimonotonicity, regularity and duality for nonlinear systems of partial differential equations. Ann. Mat. Pura Appl. 169, 321–354 (1995) Book: Geddes, K.O., Czapor, S.R., Labahn, G.: Algorithms for Computer Algebra. Kluwer, Boston (1992) Book chapter: Broy, M.: Software engineering — from auxiliary to key technologies. In: Broy, M., Denert, E. (eds.) Software Pioneers, pp. 10–13. Springer, Heidelberg (2002)  In the text, the references should be as follows:  Negotiation research spans many disciplines (Hamburger 1995).  Thank you for your help! I recently bought a Minolta film camera and it had some film with it. The film is dated 1991 - 1994. Can I use the film? I know it has been discussed that it is not possible to start an application from an usb drive upon connection due to limitations of autorun (or autoplay??) in Win 7. But it is possible to create a scheduled task having an event type trigger. Surely there must be an event occurring when the drive -- or any USB device, for that matter -- is connected.    Does anybody have the slightest idea which Event ID should I use? Or at least what type of event? Where can I find the event in event viewer? We want to find the solution $x$ to the congruence system  $$\begin{align} x &amp;\equiv r_1 \!\!\!\pmod{\!m_1}\\ x &amp;\equiv r_2 \!\!\!\pmod{\!m_2}\end{align},\ \ {\rm where}\ \  \gcd(m_1, m_2) = 1$$  These can be rewritten as  $$\begin{align} x &amp;= r_1 + m_1 j\\ x &amp;= r_2 - m_2k\end{align}$$  for unknown integers $j, k$. So we set those two equations as equal and rearrange them to  $$m_1j + m_2k = r_2 - r_1$$  Now assume we perform $\text{egcd}(m_1, m_2)$, which gives us the solution to  $$m_1u + m_2v = \gcd(m_1, m_2)$$  Let the integer $\,h\,$ make $\,h \gcd(m_1, m_2) = r_2 - r_1$.  Then $\qquad hm_1u + hm_2v = h\gcd(m_1, m_2) =  r_2 - r_1 = m_1j + m_2k$  At this point I am lost because I don't think we can just assume  $hm_1u = m_1j$ and extract $j = hu$.   How do I get the values of $j$ or $k$ so I can get the value of $x$? vertical lines in matrix using tikz package my problem is interconnected to my two previous posts ( and) and i've tried to incorporate answers into solution but without success.   My task is this matrix multiplication with added description:   and my so far code follows:  \documentclass{article} \usepackage{tikz,amsmath}  \begin{document} \begin{tikzpicture} \node[minimum height=0cm,minimum width=2cm] (m) {}; \path[shade,draw] (0,2) -- (0,5) -- (3,5) -- (3,0); \draw (0,0) --(0,5); \draw (3,0) --(0,2); \draw (3,0) --(3,5); \node (r11) at ([xshift=0.6cm,yshift=4cm]m.south) {$S_{11}$}; \node (r11) at ([xshift=2.5cm,yshift=4cm]m.south) {$S_{12}$}; \node (r11) at ([xshift=2.5cm,yshift=2.15cm]m.south) {$S_{22}$}; \node (r11) at ([xshift=0.6cm,yshift=2.15cm]m.south) {$S_{21}$}; \node (r11) at ([xshift=0.6cm,yshift=2.6cm]m.south) {$--------------$}; \node (r11) at ([xshift=0.6cm,yshift=1.5cm]m.south) {$--------------$}; \end{tikzpicture} \[ \begin{bmatrix} \begin{equation}        wn_{1}           \\[0.3em]        wn_{2}       \end{bmatrix}  \]  \end{document}       with following output:      I am not able to add vertical line and nodes and incorporate the matrix into document (vector that follows behind the matrix is not centered). Problem with nodes and incorporation is the same as in . Our company would like to understand the effects:   If we have single table with Primary Key Identity column, int primary key IDENTITY(1,1),  and the Application is conducting multi-threading parallel processing, trying to conducts 1000s of simultaneous inserts on one table.   Would the identity primary key column fail, with a primary key violation in any way, for example: processors are trying to input the same identity number?  Or was SQL designed to be successful even in multithreading parallel insert?  Note: IDENTITY_INSERT is OFF Triple integral limits over pyramid What's the best way to season a cast iron skillet? I just purchased a new cast iron skillet. What's the best way to season it?   And if I need to re-season an old pan, is the process any different? If just a single photon hit a single slit interferometer, what would happen? Would you just see a dot on the screen, or would there be a diffraction pattern? Furthermore, if you had a double slit interferometer but also had which-path information would there still be a diffraction pattern even though there is no interference? Number of homomorphisms from $(\mathbb Q^+ , \,\cdot\,)$ to $(\mathbb Z_n , +)$ How many homomorphism are there from $(\mathbb Q^+ , \,\cdot\,)$ to $(\mathbb Z_n , +)$?   Could anyone give a hint how to proceed? I couldn't even start I am looking for idioms or informal/slang/colloquial expression for some people that make you think that they are able of building a skyscraper, constructing a spaceship, playing the piano better than Mozart or something very fancy that requires remarkable skills, but when it comes to practice they prove to be completely inadequate. In school, I have always seen sets. I was watching a video the other day about functors, and they started talking about a set being a collection, but not vice-versa. I also heard people talking about classes. What is their relation? Some background would be nice.   It has to do with something called Russell's paradox, but I don't know what that is.   I think that the difference between a family and a set is that the former is a function and the latter is a set. Is this right? How do I report a bug?
