How is a Kelvin Pod different than a standard Escape pod? Is it possible to test apex that relies on field history tracking? I have some code that relies on field history tracking by querying the History for a custom object. This works fine, but it appears that the history records aren't created during the test so none of my tests will pass. The three lengths \textwidth, \linewidth and \hsize seem to all hold the width of the current line. At least I never saw some real difference between \textwidth and \linewidth in my code. Both seem to be identical even when changed, e.g. by a minipage environment.  Could someone give me an elaborate explanation of the differences between these lengths? I like to understand them in detail. I know that the first two are from LaTeX and the latter one from plainTeX.  There is also \columnwidth which seems to be identical to \linewidth or \textwidth in one-column mode, right? Except when the line is reduced by a minipage or quote etc. environment. Mutual Independence Definition Clarification Number theory proof mod p For a given prime $p$ and integer $k$,  $k∈&lt;1, p-1&gt;$ $S(k)$ is defined as a sum of remainders of $k, k^2, k^3, ..., k^{p-1}$ when divided by $p$. Prove that $S(k)=\frac{1}{2}p(p-1)$ is true for an odd number of different k. I managed to prove that $S(p-1)=\frac{1}{2}p(p-1)$ but can't see how to do it further. OK guys I have this problem:  For $x,y,p,q&gt;0$ and $ \frac {1} {p} + \frac {1}{q}=1 $ prove that $ xy \leq\frac{x^p}{p} + \frac{y^q}{q}$  It says I should use Jensen's inequality, but I can't figure out how to apply it in this case. Any ideas about the solution? Cyclic Group Generators of Order $n$ How many generators does a cyclic group of order $n$ have? I know that a cyclic group can be generated by just one element while using the operation of the group.  I am having trouble coming up with the generators of a group of order $n$.  Any help would be great!  Thanks! Changing color and fonts of itemize How can I change the font and color of a particular command in a LaTeX document?  For example I want all the text that follows the \item tag to be gray and the font should be different from the rest of the document , which i can specify ... I'm getting these errors ramdomly, and I don't know if its normal or not.

Thanks in advance for your help. How to register domain for 15 years? I have heard that Google trust that website which has long expiry date. that want to know how can I register my domain for a long period. Evans PDE Problem 5.15: Poincaré inequality for functions with large zero set I have trouble proving the following problem (Evans PDE textbook 5.10. #15). Could anyone kindly help me solving the problem? I know that I should somehow use Poincaré inequality but I still cannot solve it.   Fix $\alpha&gt;0$ and let $U=B^0(0,1)\subset \mathbb{R}^n$. Show there exists a constant $C$ depending only on $n$ and $\alpha$ such that $$ \int_U u^2 dx \le C\int_U|Du|^2 dx,  $$ provided that $u\in W^{1,2}(U)$ satisfies $|\{x\in U\ |\ u(x)=0\}|&gt;\alpha$. The order of words in a clause: "tell me who is the real man" vs. "tell me who the real man is" The curious case of Dmitri Valtane Trig integral $\int ( \cos{x} + \sin{x}\cos{x}) \, dx $ Assume we have:  $$ \int (\cos{x} + \sin{x}\cos{x}) \, dx$$  Two ways to do it:  Use $$\sin{x}\cos{x} = \frac{ \sin{2x} }{2} $$ Then $$ \int \left(\cos{x} + \frac{\sin{2x}}{2} \right) \, dx = \sin{x} - \frac{ \cos{2x} }{ 4 } + C. $$ The other way, just see that $ u = \sin(x), du = \cos(x)dx $, $$ \int ( \cos{x} + \sin{x}\cos{x}) \, dx = \sin{x} + \frac{\sin^2{x}}{2} + C. $$  Now the part I don't see fully is, why aren't these results completely equal?  Taking the 2nd result, \begin{align} \sin{x} + \frac{\sin^2{x}}{2} &amp;= \sin{x} + \frac{1}{2} \, \left( \frac{1 - \cos{2x}}{2} \right) \\ &amp;= \sin{x} + \frac{1}{4} - \frac{\cos{2x}}{4}. \end{align}  So you have to absorb $\frac{1}{4}$ into $C$ for them to be equal.  Shouldn't they be equal straight away? How to handle repeated references in footnotes? Often floats may land quite a bit later in the document than the point they are created, sometimes after a section break.  Is there a way to force a new section to start on a new page, after any unplaced floats? How many arrangement of the letters in MISSISSIPPI have at least 2 adjacent S's?  I was thinking that I can glue two of the S's together, so there will be 9 letters plus the special letter SS, and the number of arrangements will be $10!/(2!2!4!)$, this is not the correct answer, but what is wrong with my reasoning.  (the correct answer is $11!/(4!4!2!)-7!/(4!2!)\binom{8}{4}$, I understand the solution) I have my mobile phone (Samsung Galaxy S2) running on ICS. Recently I activated Microsoft Exchnage ActiveSync to connect to my corporate email. It disabled all the security options like 'Pattern Unlock'. I hated it, and removed my microsoft active exchange account from the phone, but these options are still disabled. How do I get it enabled? I was thinking about this issue from time to time but I didn't know whether it really exists or just an speculation on my side until today when I woke up [!], I saw  downvoted (in the meantime I'll leave that answer unedited for the sake of discussion; note that this is just a sample. I'm not asking "how to deal with this specific answer." The question is completely general as it's nearly impossible to keep track of all of your answers to see whether they require updating or not). While the downvoter didn't explain a thing, I suspect the reason is that the answer is no longer applicable (It's one of the new features in iPhone OS 3.0). As we go to celebrate a long sequence of birthdays for Stack Overflow (hopefully!), we're going to see lots of answers become obsolete. How we're going to deal with this issue?
