Java toString() using reflection? Show $\lim_{n \to \infty} n^{-1} E \left( \frac{1}{X}1_{[X>n^{-1}]} \right) =0$ Suppose $X$ is a non-negative random variable satisfying  \begin{align*} P[0 \le X &lt; \infty ]=1. \end{align*} Show   a)  \begin{align*} \lim_{n \to \infty} n E \left( \frac{1}{X}1_{[X&gt;n]} \right) =0 \end{align*} b)  \begin{align*} \lim_{n \to \infty} n^{-1} E \left( \frac{1}{X}1_{[X&gt;n^{-1}]} \right) =0 \end{align*}  What I did  I showed part a) already here is the proof:  \begin{align*} n E \left( \frac{1}{X}1_{[X&gt;n]} \right) \le n E \left( \frac{1}{n}1_{[X&gt;n]} \right)=n\cdot\frac{1}{n}P[X&gt;n]=P[X&gt;n] \end{align*} So $\lim_{n \to \infty} n E \left( \frac{1}{X}1_{[X&gt;n]} \right) \le \lim_{n \to \infty} P[X&gt;n]=0$.  What about part b)? The same techniques no longer works.  I was thinking that  \begin{align*} \lim_{n \to \infty} n E \left( \frac{1}{X}1_{[X&gt;n]} \right) \le \lim_{n \to \infty} n E \left( \frac{1}{X} \right) \le 0 \end{align*} but I am not sure that $E \left( \frac{1}{X} \right) &lt; \infty$ How to make use of Devel debugging functions on large or complex objects I am having trouble making real use of Devel's debugging functions kint() and dpm() in my modules and twig templates. They work fine for primitive variables, flat arrays and such, but if I want to inspect into some object like an EntityRerefenceFieldItemList they either cause the site to crash (white page) or generate so much data such that the scripts for expanding the list no longer work.  How do I circumvent these problems? Remove entire row in a file if first column is repeated How can I make a hexagonal grill? I have this value    How to read that in English? translating from my native language, I would say     Ten base of nine.   but is that really correct? Is the XP for an encounter split among the party members or not? At this point, I am unclear as to how to handle encounter XP. Does each surviving party member receive a proportional share, or the full amount? That is, assume a 4-character party had completed an encounter worth 400 XP. Would each party member receive 100 XP, or 400 XP? I understand that clicking "shut down" from the menu that comes up on clicking the cogwheel triggers the following command to be executed:  dbus-send --system --print-reply --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Shutdown   However, when I execute this command on a terminal, I get the following error:  Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files   Is it because 14.04 uses some other service for shutting down, or am I doing something wrong?    Note: This question is in follow-up of: Justify text in moderncv cover letter I am writing a cover letter and CV using moderncv. Everything works fine so far, but the text in the cover letter is not justified. I think it is good that it is not hyphenated, but it would look much nicer if the text was justified.  Here is a minimal example:  \documentclass{moderncv} \moderncvstyle{classic}  \usepackage{lipsum} % just for dummy text  \firstname{John} \familyname{Doe}  \begin{document} \recipient{Prof.\ Dr.\ Foo Bar}{} \opening{Dear Professor Dr.\ Bar,} \closing{Yours sincerely,} \enclosure[Attached]{curriculum vit\ae}  \makelettertitle \lipsum[1] \makeletterclosing  \clearpage  \makecvtitle  \section{Education} \cventry{2009--present}{PhD Student}{here}{and}{there}{} \end{document} I'm actually at the cemetery at White Orchard. There is a white question mark and some little red arrows.  What are this little red arrows?  Do they point to something dangerous? How to check who owns the Slack's workspace? I'd like to check who owns (or at least some kind of public profile page) some workspace based on its subdomain (e.g. xyz.slack.com).  Is it possible? I have the following configuration, but I have not able to find any documentation on how to set a maximum backup files on date rolling style.  I know that you can do this with size rolling style by using the maxSizeRollBackups.  &lt;appender name="AppLogFileAppender" type="log4net.Appender.RollingFileAppender"&gt;     &lt;file value="mylog.log" /&gt;     &lt;appendToFile value="true" /&gt;     &lt;lockingModel type="log4net.Appender.FileAppender+MinimalLock" /&gt;     &lt;rollingStyle value="Date" /&gt;     &lt;datePattern value=".yyMMdd.'log'" /&gt;     &lt;layout type="log4net.Layout.PatternLayout"&gt;       &lt;conversionPattern value="%d %-5p %c - %m%n"  /&gt;     &lt;/layout&gt; &lt;/appender&gt; What are best practices/important steps when the Windows Server machine hosting SQL Server 2008 R2 is moved to another domain?   What steps definitely/might need to be done for SQL Server before and after the new domain is joined? Combinatorial proof of an identity with squared binomial coefficients Is it true that $\sum_kk\binom{n}{k}^2=n\binom{2n-1}{n-1}$? (I proved it using generating functions). Could you help me to prove it combinatorially? please For $a,b,c&gt;0$, Find $$ \lim_{n \to \infty}\left(\frac{a^{1/n}+b^{1/n}+c^{1/n}}{3}\right)^n$$  how can I find the limit of sequence above?  Provide me a hint or full solution. thanks ^^ Suppose $a_1, a_2,\dots , a_n$ are $n$ positive real numbers with $a_1a_2 \dots a_n = 1$.   Then what is the minimum value of $(1 + a_1)(1 + a_2). . .(1 + a_n)$ ?    I think $(1 + a_1)(1 + a_2). . .(1 + a_n)$ takes its minimum value when $a_1=a_2=\dots=a_n=1$ and thus the minimum value is $2^n$.  I don't know how to prove it. Please help. Is there any module or some configuration that I can define the meta tags for the views page display in drupal 7 using  3.0? When & how did Yoda come to know about the Rule of Two? How does a calculator calculate the sine, cosine, tangent using just a number? Sine $\theta$ = opposite/hypotenuse   Cosine $\theta$  = adjacent/hypotenuse   Tangent $\theta$  = opposite/adjacent      In order to calculate the sine or the cosine or the tangent I need to know $3$ sides of a right triangle. $2$ for each corresponding trigonometric function. How does a calculator calculate the sine, cosine, tangent of a number (that is actually an angle ?) without knowing any sides? My last name is not the same on ticket as on passport; rest of details are same I'm traveling from JED Saudi Arabia to Singapore by Saudi airlines. My last name doesn't match the passport. But all other details are same, e.g. passport no., DOB, etc.
