When to use LinkedList over ArrayList in Java? 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? Suppose that $f:\Bbb R\to \Bbb R$ is continuous and that $f(x)\to 0$ as $x\to \pm\infty$. Prove that $f$ is uniformly continuous.   Since $f(x)\to 0$ as $x\to \pm\infty$ we have $|f(x)|&lt;\epsilon $ whenever $x&lt;-K$ and $x&gt;K$ where $K&gt;0$.  Also $f$ is uniformly continuous on $[-K,K]$ as the domain is compact.  Hence $f$ is uniformly continuous in $(-\infty,-K)\cup [-K,K]\cup (K,\infty)$.  But how to conclude that $f$ is uniformly continuous on $\Bbb R$ from above as I may chose $x\in (-\infty,-K);y\in [-K,K]$ ,how to conclude that $|f(x)-f(y)|&lt;\epsilon $ from above for a given $\epsilon$?

How do I create a reflective white material? I'm pretty new to this and this is my first question here, any help would be greatly appreciated.  So basically what I want to achieve is a floor material as seen in this photo...    ...the reflections are very crisp but dim.  With a glossy shader I get the following results:    First picture: reflections are blurry  Second picture: roughness of the material looks right but reflection is bright red  Third picture: If tinted in any other color than white, it seems to produce the result I want. Reflection is sharp and gets tinted blue. What I need is the reflection to be tinted white.  Thanks for any help. I read on  that the netbook edition of Ubuntu was discontinued and that it is now integrated into the main distribution (as of 11.04).  I tried 11.04 on my new Samsung NC110-A06AU with 10.1" 1024x600 display. Most things worked out of the box, but some (like backlight power control) needed some  before they began to co-operate.  One thing that seems to be an ongoing problem is the resolution.  At 1024x600, most of the dialogue boxes run off the bottom of the screen, including the update manager. I have tried 11.10 beta 1 and it has the same problem.  Is there any way to fix this, or at least make it more usable? (I suspect not). Given the recent rise in popularity of netbooks, do you think Ubuntu will include a low-resolution-friendly version in the near future?  How well does KDE deal with these low resolutions? I noticed KDE Plasma has a netbook interface. Is it worth switching for that?

Maybe he was a good actor and a double agent. Was it just that he loved (or pretended to) Lily or he used legilimency? Is there a word for two persons dodging each other on the street? When can a sum and integral be interchanged? Let's say I have $\int_{0}^{\infty}\sum_{n = 0}^{\infty} f_{n}(x)\, dx$ with $f_{n}(x)$ being continuous functions. When can we interchange the integral and summation? Is $f_{n}(x) \geq 0$ for all $x$ and for all $n$ sufficient? How about when $\sum f_{n}(x)$ converges absolutely? If so why? I have just bought a new bike and had it about a month now. I don't really know much about bikes but I do know how to repair an inner tube.  I have had one puncture and just bought a new inner tube. It worked for a few days and then went down again so this time I got a puncture repair kit. I took the inner tube out to check for any punctures and found nothing. I put it in water and pumped it up and there were no bubbles. I went around the entire tube pushing it next to my ear and heard nothing. I checked the tire to see if anything was wrong - there was nothing that I could see.   So I put it all back together and took it for a ride and got about half a mile and the tire was flat. I pumped it up and got about another half a mile and it was flat again.  Do you have any suggestions for me? I know that there is no vector space having precisely $6$ elements. Does every set have a group structure? Show that if $ R $ is an integral domain then a polynomial in $ R[X] $ of degree $ d $ can have at most $ d $ roots Show that if $ R $ is an integral domain then a polynomial in $ R[X] $ of degree $ d $ can have at most $ d  $ roots.  Thoughts so far:  I feel like I might be missing something here. If $ R $ is an integral domain, then so is $ R[X] $. The factor theorem gives a correspondence between roots and factors. Clearly (is this clear?) a polynomial of degree $ d $ can't have more than $ d $ irreducible factors. Could $X^3 + X + 1$ have a root in $E?$ Consider the irreducible polynomial $g = X^4 + X + 1$ over $F_2$ and let $E$ be the extension of $F_2 =$ {0, 1} with a root $α$ of $g.$  Could $X^3 + X + 1$ have a root in $E?$  When working through this sheet Ive come across this question in which im not sure how to answer so any help will be appreciated How to jump to the region header from the endregion tag in c# visual studio 2012? Django: How can I protect against concurrent modification of database entries I have used the code shown below to draw a static CMOS inverter. I have tried to use the TikZ library calc to calculate the point at which drains of the PMOS and the NMOS devices meet; and the mid-point of the line which connects the gates of the two devices. Apparently calc gets the y coordinates of the points right. However, calc seems to get the x coordinates of the points wrong. What could I be doing wrong?  Here is the TikZ code:  \documentclass{standalone} \usepackage[americaninductors]{circuitikz} \usetikzlibrary{calc} \begin{document} \begin{circuitikz} \draw % Draw MOSFETs: (0,0) node [pigfete,yscale=-1,anchor=S] (M1) {} (M1.D) node[nigfete,anchor=D] (M2) {} (M1.G)--(M2.G) % The line connecting the gates of the MOSFETs. ; % Draw the power rails: \draw ($(M1.S)-(2.0,0)$) -- (M1.S) -- ($(M1.S)+(1.2,0)$); \draw ($(M2.S)-(2.0,0)$) -- (M2.S) -- ($(M2.S)+(1.2,0)$); % Input and output nodes: \node (I) at ($0.5*(M2.G)+0.5*(M1.G)$) {}; % The mid-point between the gates. \node (O) at (M1.D) {}; % The point at which the drains of the MOSFETs are conneted. % The Input and output lines. \draw ($(I)-(.8,0)$) -- (I); \draw (O) -- ($(O)+(0.8,0)$); \end{circuitikz} \end{document}   Here is the figure that I get: Note that that input and the output lines are not connected to the rest of the circuit. Can we attribute the problem of the lines not being connected, to the rest of the circuit, to the way I am using calc? How to change the hostname of a RHEL-based distro?
