Interesting boolean syntax
What does the |= operator do in Java?
What are my best options for a tripod for up to $100? I'm looking to buy a tripod + head (for my Canon 40D), but am not sure if I want to spend more than $100 on it.  So can you suggest options for best tripods for $100 or less? Or, is it important to spend more than that on a tripod?  Extra props for options which might be available in India. integral of $\int_{0}^{1}\frac{\ln(x^{2}+1)}{x+1}dx$ using contour integration? I have an interest in contour integration. I am not that good at it, but I enjoy learning what I can about it.  Here is a version of a rational log integral rarely encountered.  $\displaystyle \int_{0}^{1}\frac{\ln(x^{2}+1)}{x+1}dx=\frac{3}{4}\ln^{2}(2)-\frac{{\pi}^{2}}{48}$  I can do this using real methods (via double integral and substitution). I can post my workings if anyone would be interested.  My question is, can this be evaluated using contour integration due to the limits being $[0,1]$ instead of $[0,\infty)$?.  Contours may not be the most efficient way to go about it, but what is the course of action when the limits are 0 to 1 instead of 0 to infinity?. How long can I stay in the UK during a 1-year period? I am a Chinese citizen holding a HK SAR passport. How long am I able to visit the UK within a 365-day period?  My stamp is for 6 months. Could I leave within 6 months but re-enter again a couple of weeks for another 6 months? MySQL GUI Tools 15V 3A dc motor PWM frequency setting What is a suitable frequency for 15V/3A DC motor? Is there any effect on the motor when the frequency is changing? I am confused with this until now and the Internet shows a lot of theory that confuses me. Console.WriteLine and generic List I frequently find myself writing code like this:  List&lt;int&gt; list = new List&lt;int&gt; { 1, 3, 5 }; foreach (int i in list) {     Console.Write("{0}\t", i.ToString()); } Console.WriteLine();   Better would be something like this:  List&lt;int&gt; list = new List&lt;int&gt; { 1, 3, 5 }; Console.WriteLine("{0}\t", list);   I suspect there's some clever way of doing this, but I don't see it. Does anybody have a better solution than the first block? Client-Side Rendering/JS Link documentation? Has there been any sort of documentation or anything like that released for SharePoint 2013 Client-Side Rendering/JS Link?  Anthing unofficial? Any dates for when documentation might be released? Multi-OS Portable TeX system Can a PC with the Alert feat alert his friends? Assume the following situation: The party has been surprised by an ambush. Every PC is surprised except PC Bob because he has the Alert feat. Thanks to his high initiative bonus Bob gets to go first. He shouts "look out" to alert his party members of the imminent threat. The idea is that his party members are no longer surprised because he warned them.   While I think that this makes sense from a storytelling perspective, I am afraid this would be too strong. as it allows one PC with the Alert feat to give the "not surprised" benefit to other members of his party pretty much for free.  Is this allowed? Are there rules or an official ruling or similar on this?  If not, do you have any experience with this situation, and how did it play out in your games? Does "corresponding author" carry an implied meaning? After reading the question , I got the impression that (at least in the writers' field) the "corresponding author" flag could carry an implied meaning, such as "did more work than the other authors", or "is a more senior author". Is it the case?  I am in mathematics, a field where we typically sort the authors alphabetically, and I've never given any importance to that role (apart from "this author is willing to answer a couple of extra e-mails, if needed"). How do I install the VirtualBox version from Oracle to install an Extension Pack? How many ways can the average of n dice be a? Running tcpdump starts ssh flood I have runtime Linux running in a PLC. My development machine is running Ubuntu 14.04. The PLC and the development machine are connected through a five port switch. I ssh to PLC from my development machine to transfer executable of a networking application that I develop on my development machine.   I run tcpdump on PLC to debug the kind of packets my network application is receiving BUT as soon as I start tcpdump, there starts a flood of ssh sync and acks back and forth from my ubuntu machine to the PLC. The LED lights of ethernet controller of PLC as well on the switch start blinking rapidly. The flood overwhelms the PLC and it almost dies down while all other packets get dropped. It feels like a DOS attack whenever I run tcpdump but as soon as I stop tcpdump, everything calms down and gets back to the normal.   I would like know remedy on this problem and why it happens?     Any help would be appreciated. Prove that $\binom{m+n}{m}=\sum\limits_{i=0}^m \binom{m}{i}\binom{n}{i}$ Should I say "She is in the park" or "She is at the park"? Can I install Microsoft Office? If so, how? Where should I post my sum-up of the answers, as the OP? Show that every irrational number in $\mathbb{R}$ is the limit of a   sequence of rational numbers. Every rational number in $\mathbb{R}$ is   the limit of a sequence of irrational numbers.   How can I prove this?

We know that $f(x)=\frac{1}{x}$ is continuous everywhere except at $x=0$. But i think this in reverse manner but i dont get any example. So please help me out!
