Are any of the USB ports on a Macbook Pro "always on" Always on USB ports will provide power to a device even when the laptop is shut down. Obviously this can be problematic for battery issues, but sometimes a user wants this capability all things considered.  Do the Macbook Pro offer this on any of the USB ports and if not is there any chance its wired and just has to be enabled? Bizarre spacing with 4 $\star$s The spacing between the 3rd and 4th stars is non-existent. Anyone know what's up?    \documentclass[11pt]{article}  \usepackage{amsmath}  \begin{document}  \begin{gather*} \star\star\star\star \\ \star\star\star\,\star \\ \star\star\star\star\star \end{gather*}  \end{document} SQL Server 2008 R2 SP1  My company uses the Great Plains (GP) financial system with several customizations.  Our Value-Added-Reseller (VAR) for GP has setup most of these customizations in a separate database from the GP data called DYNCUSTOM.  In the DYNCUSTOM database is a View that is merely a SELECT * FROM a table in the GP company database (called PARTS).  I was approached by a user having problems trying to select on this view.  The error he was getting:  Msg 229, Level 14, State 5, Line 2 SELECT permission denied on object 'BM010415', database 'PARTS', schema 'dbo'   I looked at how his login was mapped and he had a database user in the DYNCUSTOM database belonging to a database role that was granted select on the view.  However, he did not have a database user in the PARTS database.    Usually the intent of a view is so that one can grant select permissions on the view without exposing access to the underlying table.  With SQL Server however, if the view crosses databases does it then change the security context being used?  Therefore, the user would also need a database user in the PARTS database as well as granted select access to the underlying table? I don't understand this. These identities are given in the online notes for MIT's 18.01 calculus class. It's related to taking the sum of two trig functions and transforming them into a single trig function. I can use the formulas to do this, but I am having trouble finding anything on the internet to use a proof for my understanding.  Thanks for any responses!  EDITED (added after the first answer):  Sorry, the identity goes like this:  $A\sin{k(x-c)}=a\sin{kx}+b\cos{kx}$ ,  with the relationships  $a=A\cos{kc}$ , $b=-A\sin{kc}$ , $A=\sqrt{a^2+b^2}$ , and $\tan{kc}=-b/a$ If $f$ is continuous and $\,f\big(\frac{1}2(x+y)\big) \le \frac{1}{2}\big(\,f(x)+f(y)\big)$, then $f$ is convex Let $\,\,f :\mathbb R \to \mathbb R$ be a continuous function such that $$ f\Big(\dfrac{x+y}2\Big) \le \dfrac{1}{2}\big(\,f(x)+f(y)\big) ,\,\, \text{for all}\,\, x,y \in \mathbb R, $$ then  how do we prove that $f$ is convex that is $$ f\big(tx+(1-t)y\big)\le tf(x)+(1-t)f(y) , \forall x,y \in \mathbb R , t\in (0,1)? $$ I can prove it for dyadic rational's $t=\dfrac k {2^n}$ and then argue by continuity ; but I would like a more direct proof .

When I turned it on I got some kind of walk through on how to use it. I couldn't cancel it. So I turned off my phone.   When I turned it back on again it took me 15 minutes to unlock my phone. Apparently I had to touch a button to give it focus and then double tap it to click it.   Now my question is: how do I turn this off?

I have a Multisite Wordpress installation with 7 different blogs. I want to show an aggregate of the summaries of posts from those 7 blogs in the main blog. Do you know a good way to do this? Determining if trees within forest gaps are clustered using R? The attached dataset shows approximately 6000 saplings in approximately 50 variable sized forest gaps.  I am interested in learning how these saplings are growing within their respective gaps (i.e. clustered, random, dispersed).  As you know, a traditional approach would be to run Global Moran's I.  However, aggregations of trees within aggregations of gaps seems to be an inappropriate use of Moran's I.  I ran some test statistics with Moran's I using a threshold distance of 50 meters, which produced nonsensical results (i.e. p-value = 0.0000000...).  The interaction among the gap aggregations are likely producing these results.  I have considered creating a script to loop through individual canopy gaps and determine the clustering within each gap, although displaying these results to the public would be problematic.    What is the best approach to quantify clustering within clusters?

Macro with lstlisting inside I have been following  about using \NewDocuentCommand with lstlisting and the accepted answer is nice except it is too big and it doesn't quite work for me.   I came up with this example to test xparse:    \documentclass{article} \usepackage{xparse} \usepackage{listings}  \ExplSyntaxOn \NewDocumentCommand{\code}{m +v}{     \begin{lstlisting}[style=#1,numbers=none,xleftmargin=0.35cm,framesep=0mm]         #2     \end{lstlisting} } \ExplSyntaxOff  \begin{document}  \code{C}{ int x = 200; unsigned int y = 0; }  \end{document}   Like stated in the  I first used m as a normal parameter and then +v as a multiline verbatim parameter, but it fails. It looks like I am still missing something... What does this bag with a checkmark on it next to Roblox usernames mean? I have an image with a woman, and I need to make an ad (size 260mmx125mm). I want to put the woman to the left side, but then right side becomes empty. So, how I should solve the problem? I have picked the color from image, but it is definitely different than in the actual picture.  Should I use the Clone Stamp Tool in Photoshop, or there is a better way to do this?  By the way, it will be used in print, so I need a good quality.
