I am using texlive2014.But When i import a picture,it just move away.  This is my source code:  \usepackage{graphics}   \begin{figure}[htbp]     \centering     \includegraphics[scale=0.5]{ProjectStartWorkflow.jpg}     \caption{项目启动流程} \end{figure}   My compiler is xelatex.The picture move to next page,i can not understand where i am going wrong?
Is there any package or a method to force LaTeX to keep floating environments like table and figure closer to where they are declared?
How to create a rounded cone Version tags reloaded I'm getting sick of version numbers in tag names (aka version tags). Look,      I just want them all to be just . They are all about JSF. I browse and answer questions about JSF. I don't want to browse in all those different tags. I don't want gold badges for both  and . I can't hammer a duplicate  question because I don't have a gold badge for that. Across years I observed that a version tag is usually only picked by the asker when a &quot;relatively new&quot; or &quot;relatively old&quot; version is being treated in the question. When the &quot;currently mainstream&quot; version is being treated,  or when the asker is &quot;more proficient&quot; in the language, then askers often just pick the versionless . While moving in time, this may cause confusion by future readers when the version isn't explicitly specified anywhere in the question. I try to maintain them by adding/removing the version tag depending on its relevance, and by adding the versionless tag when it's absent. It only feels a neverending story. I'm sure other tag caretakers also have mixed feelings on this. I propose to normalize the version from the tag name:  Ban version numbers in tag names in the model (not in the UI). Add an optional single-choice version field to the Tag entity in the model. Users with edit privileges (no suggested edits please) must be able to change versions. Users with gold tagbadges must be able to add and edit versions. I'd imagine the version edit thing to be reachable via that tag info popover (when you hover the tag). Tags themselves however should look exactly the same, the version just separated with e.g. a hyphen from the tag name.  When in place, migration of existing version tags should be piece of cake. There's apparently already a script in place which recognizes version tags, it could be reused to re-match current tags and extract the version from it into the new version field. The alternative would be to automatically add the versionless tag when a version tag is being used. But this is IMO only tag pollution.  I'm posting this on meta.se instead of meta.so because version numbers aren't only on SO a problem, but on basically all HW/SW related sites. Complex zeros of the polynomials $\sum_{k=0}^{n} z^k/k!$, inside balls Holomorphic function $f:B(0,1) \to B(1,4)$ with $f(0)=3$ and $f(\frac{1}{2})=1$ Problem  Find all holomorphic functions $f:B(0,1) \to B(1,4)$ that verify $f(0)=3$ and $f(\frac{1}{2})=1$.  I have no idea how to attack this problem,since it comes after an exercise related to Schwarz lemma, I thought that maybe the idea is to somehow apply the lemma in this problem as well, but if that is the case, I don't know how could I use it. I would appreciate suggestions. Tag score calculation wrong in Android App How can I determine if it is possible to check luggage during a layover? A common desire among some travelers with long layovers is to leave the airport for a while, and perhaps do some shopping, or even buy goods in the airport.  But this then often necessitates the ability to check additional luggage during the layover, for the remainder of the journey.  There might be other reasons to want to check luggage mid-journey as well.  Are there any general rules one can use to determine whether this is an option in a given airport when traveling with a given airline, and the associated costs (when it is possible)? How to implement "confirmation" dialog in Jquery UI dialog? How to set ctrl+c to copy, ctrl+v to paste and ctrl+shift+c to kill process in xfce4-terminal? Hello I can't find the option to reassign shortcuts in xfce4-terminal 0.6.3. I'd like to reassign ctrl+c to copy, ctrl+v to paste and ctrl+shift+c to kill process. I know I can do that easily under gnome-terminal but since I'm using xfce I would like to avoid installing all the dependencies for gnome-terminal. Any idea on how to achieve that ? Converting a .lasd (Lidar) coordinate system? How can one change a coordinate system for a .lasd (Lidar) dataset?  The file is currently in UTM_Zone_15N and I am trying to convert it to IL_East. First let me explain what I mean by "transitive" Suppose that the price of product A and the price of product B has a correlation of .5 Suppose also that the price of product B and product C has a correlation of .5  One might thing that if correlation(A,B) = .5 and correlation(B,C) = .5 then correlation(A,C) > 0, but with an intuitive example we can see why this is not the case:  Suppose that A is a fruit salad made of papaya and banana, suppose also that B is a fruit salad made of banana and strawberry and, finally, suppose that C is strawberries and cream. Clearly, when the price of banana goes up, both the price of A and B will go up; when the price of strawberry goes up the price of B and C will go up; but since A and C have no ingredients in common, their price isn't correlated.  My question is which statistical concept captures this intuitive idea. Is it the concept of dimensions?  What do I mean by transitive? Let me define the binary operator X corr? Y as 1 if correlation(X,Y) != 0 and 0 otherwise, so:   A corr? B = 1, B corr? C = 1, but  A corr? C could be = 0   If corr? was transitive, then A corr? C = 1 Least expensive way to boost DC voltage What would be the least expensive way to boost a DC voltage?   The aim is to convert 1.2&nbsp;V/1.5&nbsp;V (from an AA/AAA cell) to 3.3&nbsp;V to power a small 8-bit microprocessor, like Atmel ATtiny45 or ATtiny2313, and also (if possible) 6&nbsp;V to power a buzzer.  Also, what would be the maximum current one could draw safely from an alkaline battery, after boosting it to 3.3&nbsp;V/6&nbsp;V?  Finally, how I could compute the duration for which the alkaline battery would last, given a certain consumption? I am from Bangladesh, and I have an Indian tourist visa, which I received from the Indian High Commission in Bangladesh. At this moment I am in Bhutan. Now I want to enter India by air. Is it possible? And will I face any problems when I come back from Kolkata to Dhaka? Obviously, you can use the | (pipe?) to represent OR, but is there a way to represent AND as well?  Specifically, I'd like to match paragraphs of text that contain ALL of a certain phrase, but in no particular order. Printing an array to a file with each element of the array in a new line in bash java.net.SocketException: Connection reset When/Why Did Love Escape Voldemort? We know that Voldemort does not love. He does not understand it, nor (generally) the magic that it possesses. He knows  of the sort.  [...] &quot;you possess in such quantities and which Voldemort has not at all.&quot; [...] &quot;because he could not bear to reside in a body so full of the force he detests. In the end, it mattered not that you could not close your mind. It was your heart that saved you.&quot; (Harry Potter and the Order of the Phoenix, page 1075)  The above confirms it (although I believe there is a better quote), though  reinforces it. The fact that he hugs so awkwardly shows that he does not really know how, due to his lack of love. I realize that Voldemort's appearance started to change after he started to create Horcruxes, but surely he had an ounce of love when he was a child? The hugging scene perhaps shows that he never once loved his whole life (possibly due to the love potion with his parents?). If so, when did Voldemort begin to have no love at all, and why? What is the word for when someone is overly nice and actually isn't nice at all? What is the word for when someone is overly nice and actually isn't nice at all because of the unnecessary added information/comments? For example, they will say things like "Your hair looks so good that wayyyy omg you should do it that way ALL the time! Looks way better than how you usually do it." And the word I'm looking for is not passive aggressive and it is not sarcasm. There is a word for these types of people. What is it? These people think they're being kind but actually blunt and rude. Another example would be for someone to say "hey you're beautiful, but maybe if you didn't wear harsh makeup you would look better" and they intend to sound like they're being nice when you know they don't like you and are saying in out of spite. du not accounting for space shown by df I have a CentOS 7.2 (minimal) VM running in a vSphere cluster, which has a 16G drive formatted as XFS under the default full-disk usage partitioning scheme from the CentOS installer. The system is running a test httpd service (all software from the default centos repos), but its space usage on disk is growing. This is in part from problematic apache error/access logs (2+GB in size), and removing these longs frees up some space. What is eating the drive space isn't so much a concern for me (I'll just nuke and pave this eventually). However, when I run df an du to check file sizes, I get a discrepancy and this is what's confusing.  First I run df -h to view filesystem usage:  [root@svrhttp03 httpd]# df -h Filesystem                         Size  Used Avail Use% Mounted on /dev/mapper/centos_svrhttp03-root   14G  4.8G  9.1G  35% / devtmpfs                           902M     0  902M   0% /dev tmpfs                              912M     0  912M   0% /dev/shm tmpfs                              912M   97M  816M  11% /run tmpfs                              912M     0  912M   0% /sys/fs/cgroup /dev/sda1                          497M  169M  329M  34% /boot tmpfs                              183M     0  183M   0% /run/user/0   This is showing 4.8G used on the root FS.  I then run the following to view the size of all items at the root of the filesystem:  [root@svrhttp03 httpd]# du -a -h -t 10K / 2&gt; /dev/null | grep -v -E "[A-Z,a-z,0-9]/." | sort -h 16K /home 7.4M    /root 31M /etc 97M /run 143M    /boot 324M    /var 1.3G    /usr 1.9G    /   This shows only 1.9G in use, and the reported size of all directories add up to ~1.9G, as expected.  So how can I find that ~2.9G discrepancy between what df and du are claiming for data on disk? Show that $\sum_{n = 1}^{+\infty} \frac{n}{2^n} = 2$ Label equations arbitrarily When I have equations, as in  \begin{equation} ... \end{equation}   Can I arbitrarily assign the numbers to the equations? Instead of the usual order (1), (2), (3), ..., I'd like something like (1), (2.1), (2.2), (2.3), (3.1), (3.2), (4), ...
