How do I calculate the distance of an object in a photo? Seeking copy of 19th century South African birth certificate? I'm trying to find the birth certificate of my wife's great grandmother who was probably born in Durban, South Africa in 1884. I'm currently unable to find any online resources for this.  If such a thing does not exist online, is there any other method of retrieving a copy or at least just the details? Answer turned to CW, votes pre-CW era doesn't count in tag specific stat My understanding is that if an answer becomes CW (one way or another), original author gets to keep the votes pre-CW.  Does this also keep the pre-CW vote count for the tag-specific stat? It doesn't look like it, because I checked recently and suddenly my number dropped. It looks like the tag-specific stat just counts votes for non-CW answers, and doesn't "discriminate" between the pre-CW and post-CW era. If it's eventually CW, then it simply contributes 0 votes.  I'm fine with the fact that my answer became CW (in this case, through the question having 30+ answers), but I would like to keep the votes I earned before it did for the tag stat.  Otherwise I think the system is "broken". Someone can go posting 30+ answers to questions where Jon Skeet answered, and all of Jon Skeet's answers would become CW, and he'd then be 0 at all tags. Oversized \underbrace's label causes unwanted spacing Consider this:  \left( x-1 \right) \underbrace{ \left( ? \right) }_{ \text{what is this?} }   The label is longer than the braced portion, which causes unwanted space between the parentheses.  Is there a way around that, so that the parentheses "touch" as they would normally?  Please note that I just started on LaTeX, and I'm using TexMaths inside LibreOffice Writer. What does \s! do? Why does this work: returning C string literal from std::string function and calling c_str() How to use grep/awk/unix to match all lines from one file in another file, even if they are duplicates I'm trying to retrieve the the matching lines from a file, however the file that has the "index" or list of matches to retrieve also has duplicate entries and I want to print out the duplicates as well.  Example:  File 1 (index file or list of strings to match)  abc tgf abc ggg aaa fff   File 2 (what I want to retrieve for each of the matches in file 1)  Fred   1   3   abc Amy    2   4   ggg Dan    5   6   tgf Mike   9   1   fff Steve  2   1   aaa   My desired result would be (order is not important, just that I match every line):  Fred   1   3   abc Dan    5   6   tgf Fred   1   3   abc Amy    2   4   ggg Steve  2   1   aaa Mike   9   1   fff   I'm familiar and have tried grep as follows, but it does not print the duplicate entries.  grep -Fwf file1.txt file2.txt  Fred   1   3   abc Amy    2   4   ggg Dan    5   6   tgf Mike   9   1   fff Steve  2   1   aaa What happened to Saruman after he was knifed by Grima? Saruman was one of Maiar, like Gandalf. Meaning that he had a mortal body but presumably, when that body was killed, would simply return back to his ("spirit?") being.  Is there any confirmation from Tolkien that this is indeed what happened after he was knifed by Grima? Or was he somehow completely destroyed since he was de-powered by Gandalf? Problem applying L'Hopitals rule. What is the justification for locking votes? Why am I not allowed to change my vote after some period of time? There are times when I go back to things I voted on, and decide they didn't deserve that specific vote. (I get wiser as I grow older) Proof of a combinatorial identity: $\sum\limits_{i=0}^n {2i \choose i}{2(n-i)\choose n-i} = 4^n$ Possible Duplicate:          This was part of a homework assignment that I had, and I couldn't figure it out. Now it is bugging me. Can anyone help me? Although a proof would be nice, I wouldn't mind a push in the right direction.   $\displaystyle\sum_{i=0}^n {2i \choose i}{2(n-i)\choose n-i} = 4^n$ I read it as a paperback around 2009ish. There are at least two books in the series. In the first book, we learn that the protagonist lives up in the mountains. Her people are distrusted by the people in the plains, and I think have either dark or olive skin. She leaves home to learn magic, something I think is rare in the world she lives in. When she arrives, there's a crazy power-hungry man at her destination and she has to hide who she is because otherwise he'd have her killed to prevent her from surpassing him. At some point, she winds up in a set of chambers set into the mountain where she finds a pool of water and carvings about dragons. Somehow, this leads into her learning to become a dragon, I think perhaps after meeting one. I want to say that the sequel got into her having dreams that turn out to be partly prophetic and partly communication.  One of the reasons the book sticks out in my memory is that, despite the mentions of the protagonists dusky skin, the cover depicts a fair-skinned blonde girl, I think holding a glowing globe of light. Help with packages in java - import does not work I'm a C++ developer - not a java developer, but have to get this code working...  I have 2 public classes that will be used by another product.  I used the package directive in each of the java files.    package com.company.thing;  class MyClass ...   When I try to compile a test app that uses that I add   import com.company.thing.*;   The javac compiler fails with errors about com.company does not exist.  (even if I compile it in the same directory as the class files I just made a package of)  I am sure I am doing something bone-headed and silly.  I've read the  pages and tried to set up a directory structure like /com/company/thing  etc, but either I have totally screwed it all up or am missing something else.  EDIT thanks for the suggestions - I had tried the classpath previously.  It does not help.  I tried compiling   javac -classpath &lt;parent&gt; client.java    and the result is:  package com.company does not exist   I have the code I want to import (the two java files) in \com\company\product.  I compile those fine.  (they contain MyClass) I even made a jar file for them.  I copied the jar file up to the parent directory.  I then did (in the parent directory with the client java file)   javac -cp &lt;jarfile&gt; *.java   the result is:  cannot access MyClass bad class file: MyClass.class(:MyClass.class) class file contains wrong class: com.company.product.MyClass Please remove or make sure it appears in the correct subdirectory of the classpath.   EDIT  I got the client code to compile and run if I used the fully qualified name for MyClass and compiled it in the parent directory.  I am totally confused now.    compiled with no classpath set - just   javac *.java    in the parent directory - and it worked fine.  I can get a test app to compile, but that is not going to cut it when i have to integrate it into the production code.  Still looking for help.  EDIT:  Finally - not sure why it didn't work before - but I cleaned up all the files all over the directory structure and now it works.    Thanks patching SQL Server with Availability Group and Secondary Replica What's the incentive to flag duplicates? $3^{n+1}$ divides $2^{3^n}+1$ Describe all positive integers,n such that $3^{n+1}$divides $2^{3^n}+1$. I am little confused about what the question asks-if it asks me to find all such positive integers, or if it asks me to prove that for every positive integer n,$3^{n+1}$ divides $2^{3^n}+1$. Kindly clarify this doubt and if it's the former part, please verify my solution-n=1. What's the best way to extend the User model (bundled with Django's authentication app) with custom fields? I would also possibly like to use the email as the username (for authentication purposes).  I've already seen a   to do it, but can't decide on which one is the best. I know  that uses $x={\sqrt{2}}^{\sqrt{2}}$ to prove that there must exist an irrational to an irrational power that evaluates to a rational. But I don't know if $x$ itself is known to be irrational or rational.  Could someone enlighten me? Thanks! Show $\lim \limits_{n \to \infty} \frac{a_{n+1}}{a_n} = \|f\|_{\infty}$ for $f \in L^{\infty}$ I have a question that I need help with getting started (possibly I would be back for more help).     I have a measure space $(X,A,\mu)$ that is finite, and $f \in L^{\infty}(\mu)$. Also, defined is $a_n = \int_X\,|f|^n\,d\mu$. I need to show that the limit is: $$\lim_{n\to\infty}\,\frac{a_{n+1}}{a_n} = \|f\|_{\infty} .$$   I am stuck on getting started, anybody have any suggestions?  thanks much How can I String.Format a TimeSpan object with a custom format in .NET? What is the recommended way of formatting TimeSpan objects into  a string with a custom format?
