Try using -f. Why is the mean function in Gaussian Process uninteresting? When should I use  or >()? I know that &lt;, &lt;(), &lt;&lt; all are used to give input and  &gt;, &gt;() which are used to redirect output.  But I don't know what is clear difference between them and when to use them.  Please explain in detail and along with references if possible. Thanks Is there a difference between foo(void) and foo() in C++ or C? Consider these two function definitions:  void foo() { }  void foo(void) { }   Is there any difference between these two? If not, why is the void argument there? Aesthetic reasons? What’s the rule for using “who” and “whom” correctly? I have a  beautiful  inequality, but I can only prove part of cases. Given any positive real numbers $a,b,c$, we have   $$(a^{2}+2)(b^{2}+2)(c^{2}+2)\geq 9(ab+bc+ca)$$  How can we prove this statement? Chat reputation in left bar seems different than any other reputation displayed for users Why is the Star Trek 2009 reboot called a reboot? Doctor Who (2005) isn't called a reboot. It is called a continuation of the old series. This was made possible by that regeneration ju-ju and stuff.  On the other hand, Star Trek 2009 reincarnation is often called a reboot. Nobody dared call it continuation. I don't think I need to do citation because it's common.  Now, if we actually go into the details:   The new universe contains two Spock. One is from the original timeline. The Spock Prime even gives data from the original timeline like trans-warp equation, Khan etc. We see other past data from before the timeline diverged. For example, Scott told that he transwarped Admiral Archer's dog. "Archer's dog" existed in Star Trek: Enterprise TV series.   So, why didn't the legacy survive in-universe? Why isn't it considered a continuation of the old Star Trek TV shows and movies?  Or, is the reboot word used by mistaken fans and media only?  Update: After the release of Star Trek: Beyond (2016), this is no longer a confusion as the movie showed a photo from original timeline. Is there any Stack Exchange site where the main topic is literature?  I have tried the English Language site, but it seems that it is not the appropriate site.  Perhaps the writers site would work? But, then again, the main point is different than the one I am searching for. I want to clear the inputtext used to search, and clear all search results using a commandbutton. I tried the following on the 'Reset' button I added but it only clears the inputtext and the search results are not clearing.  &lt;apex:pageBlockSectionItem &gt;                     &lt;apex:outputPanel layout="block" Rendered="true"&gt;                     &lt;apex:inputText value="{!ReportSearchString}" /&gt;                     &lt;apex:commandButton value="Search" action="{!searchReports}" reRender="ReportSearchResults, "/&gt; &amp;nbsp;&amp;nbsp;                      &lt;apex:commandButton value="Back" action="{!BackToCreateFeedPage}"/&gt;&amp;nbsp;                     &lt;apex:commandButton value="Reset" onclick="this.form.reset();return false;"/&gt;                     &lt;/apex:outputPanel&gt;                 &lt;/apex:pageBlockSectionItem&gt;                             &lt;/apex:pageBlockSection&gt;                         &lt;apex:pageBlockSection id="ReportSearchResults"&gt;                 &lt;apex:outputText value="{!warningMessage}" rendered="{!!showTable}" /&gt;                 &lt;apex:pageBlockTable value="{!reportList}" var="item" rendered="{!showTable}"&gt;                     &lt;apex:column headerValue="Report Name" &gt;                         &lt;apex:commandLink value="{!item.Name}" action="{!BackToCreateFeedPage}"&gt;                             &lt;apex:param value="{!item.Id}" name="SelectedReport" assignTo="{!selectedReportId}" /&gt;                         &lt;/apex:commandLink&gt;   This is my search function, it works fine. I need to clear the results of this search on clicking 'Reset' button.   public void searchReports()     {         showTable = false;               reportList = new List&lt;Report&gt;();          reportSearchResult = new Map&lt;Id, Report&gt;();          selectedReport = new Report();         if((ReportSearchString != null &amp;&amp; ReportSearchString != '') &amp;&amp; ReportSearchString.length() &gt;= 3)         {             reportSearchResult = new Map&lt;Id, Report&gt;([Select Id, Name From Report Where Name Like :'%'+ReportSearchString+'%' limit 2000]);              warningMessage = 'No Result Found';         }         else         {             warningMessage = 'Search text should have atleast 3 characters';         }     } Convert char to int in C# How can I pass a class member function as a callback? I'm using an API that requires me to pass a function pointer as a callback. I'm trying to use this API from my class but I'm getting compilation errors.   Here is what I did from my constructor:  m_cRedundencyManager-&gt;Init(this-&gt;RedundencyManagerCallBack);   This doesn't compile - I get the following error:      Error  8 error C3867: 'CLoggersInfra::RedundencyManagerCallBack': function call missing argument list; use '&amp;CLoggersInfra::RedundencyManagerCallBack' to create a pointer to member   I tried the suggestion to use &amp;CLoggersInfra::RedundencyManagerCallBack - didn't work for me.   Any suggestions/explanation for this??  I'm using VS2008.  Thanks!! How to make a vf page with the same look &amp; feel as salesforce1, any ideas? Error in updating to ADT rev 23 for Eclipse Calculating $1+\frac13+\frac{1\cdot3}{3\cdot6}+\frac{1\cdot3\cdot5}{3\cdot6\cdot9}+\frac{1\cdot3\cdot5\cdot7}{3\cdot6\cdot9\cdot12}+\dots? $ Does 10 heads in a row increase the chance of the next toss being a tail? I assume the following is true: assuming a fair coin, getting 10 heads in a row whilst tossing a coin does not increase the chance of the next coin toss being a tail, no matter what amount of probability and/or statistical jargon is tossed around (excuse the puns).   Assuming that is the case, my question is this: how the hell do I convince someone that is the case?   They are smart and educated but seem determined not to consider that I might be in the right on this (argument). Double dual mappings $\newcommand{\Hom}{\operatorname{Hom}}$Let $U,V$ be vector spaces. Denote the dual space of $U$ with $U^\intercal$ and the dual mapping of a linear map $\Phi$ be $\Phi^\intercal$. Define the double dual embedding on $U$ to be $\iota_U:U \to U^{\intercal\intercal}$. ($u \in U, f \in U^\intercal$) $$ \iota_U(u)(f) = f(u) $$     If $\Phi \in \Hom(V,U)$, then $\Phi^{\intercal\intercal} \circ \iota_V = \iota_U \circ \Phi:V \to U^{\intercal\intercal}$   Proof: Let $v \in V, f \in U^\intercal$. Then $$ \iota_U \circ \Phi(v)(f) = f(\Phi(v)) $$ but how do I show that $$ \Phi^{\intercal\intercal} \circ \iota_V(v)(f) = f(\Phi(v)) $$ ? I am seeing quite a few conversions which have as source "accounts.google.com" (almost 40%).  AFAIK, in the new Universal Analytics as soon as a user has a Referrer set a new session is started. So if a user is getting on my page, and creates an account using social auth (e.g. Google accounts) when being redirected back, will this create a new session? I guess this would explain that there are many conversions coming from accounts.google.com - is it safe to enter accounts.google.com into the Referral Exclusion List? And more - what about Facebook logins, those would show up as facebook.com, but i probably don't want to exclude facebook.com as referrer?  Any ideas how to deal with UA referrers and social logins? Related to Meta Super User efforts:  and Meta Server Fault efforts:  We already auto-remove negatively voted unanswered old questions automatically after 30 days, network wide, with no human intervention required. I was thinking we might extend that to remove old, unanswered zero score questions... based on the following criteria:  fewer than (question age in days * 1.5) views 0 score or lower, or 1 score or lower if the original author is deleted no answers 1 comment or fewer asked more than 1 year ago (thus based on creation date, not last activity date, so , or a user editing it, does not give a doomed question 365 more days of zombie &quot;life&quot;)  See the results of this query on:  (10509) |  (787) |  (650) This query has been refined based on the comments, and this is the final version that will roll out tonight. Every site in the network (except metas) will automatically delete old questions that meet this criteria from this point forward. How do I arrange selected vertices into a circular formation quickly?  The other answers does not have the same title as my question.
