Interpreting boxplots
Boxplot interpretation: is it correct that a boxplot is missing a whisker?
Command for forcing a pointer ungrab (captured mouse release) Sometimes Firefox doesn't release the mouse after dragging, so I need to kill the application to force it to release its pointer grab.  Is there any command to force an application to ungrab the pointer without killing it? Would NAT be eliminated transformed in ipv6? NAT is a wonderful concept used in ipv4. It is the major reason for the existence on internet, in my concerns. There are no networks in the world that doesn't work without employing NAT.  All I seek to know is that, would NAT be required if after ipv6 is implemented, would NAT be eliminated or be used in a different way(Transformed or Upgraded into a new version with some added abilities to tackle any situations or problems that the network specialists or researchers foresee). How to pass parameters in batch file and zip the file using 7z.exe? I need to create a batch file as per below requirements  1) pass path1 &amp; path2 while running the batch file  exl: testrun.bat E:\ERP\test1.txt E:\ERP\header.txt  2) Need to store these command line paths values in batch file  exl: var1=E:\ERP\test1.txt var2=E:\ERP\header.txt  3) zip the path1 using PKZIPW.exe or 7z.exe and create new o/p zip file  exl: 7z.exe u -tzip E:\Erp\Test1.zip var1  4) copy path2 in newly created o/p file  exl: copy /b var2+test1.zip E:\Erp\Final_output.zip Proving that the function is differentiable and $f'(0)=0$ Consider a function $f (x) $ such that $f (x)=\begin {cases} x^2 &amp;  \text {x=irrational}     \\ 0   &amp;\text {x=rational} \end {cases}$ Then prove that $f $ is differentiable  at $x=0$ and $f'(0)=0$ $$\text {Attempt} $$ .                  .  Now I consider two sequences $x_n=\frac {\sqrt{2}}{n},y_n=\frac {1}{n} $ one irrational one rational both going to $0$ as $n\to \infty $. But now the problem is how to consider LHD,RHD.Do we have to consider irrational case then rational case and if both limits go to same value then say that function is differentiable.I can easily see the graph on graphical calculator and verify the result but I am more interested in analytical method. Optimum Bone To Water Ratio For Pork and Beef Stocks I am tinkering with my stock recipes.   For pork stock I have been using 8 cups of water over a roasted trotter, a roasted backbone section with about 4 inches of rib attached, and a 1/4 inch slab of roasted pork belly.   For the beef stock I have been using 8 cups of water over an equivalent amount of roasted beef bones (knuckles and backbone/rib).   This gives a very flavorful stock and, for cost reasons, I want to determine how much I can reduce the concentration (by adding more water) without reaching too watery a taste.   Does anybody have any guidance on this topic? When writing custom classes it is often important to allow equivalence by means of the == and != operators. In Python, this is made possible by implementing the __eq__ and __ne__ special methods, respectively. The easiest way I've found to do this is the following method:  class Foo:     def __init__(self, item):         self.item = item      def __eq__(self, other):         if isinstance(other, self.__class__):             return self.__dict__ == other.__dict__         else:             return False      def __ne__(self, other):         return not self.__eq__(other)   Do you know of more elegant means of doing this? Do you know of any particular disadvantages to using the above method of comparing __dict__s?  Note: A bit of clarification--when __eq__ and __ne__ are undefined, you'll find this behavior:  &gt;&gt;&gt; a = Foo(1) &gt;&gt;&gt; b = Foo(1) &gt;&gt;&gt; a is b False &gt;&gt;&gt; a == b False   That is, a == b evaluates to False because it really runs a is b, a test of identity (i.e., "Is a the same object as b?").  When __eq__ and __ne__ are defined, you'll find this behavior (which is the one we're after):  &gt;&gt;&gt; a = Foo(1) &gt;&gt;&gt; b = Foo(1) &gt;&gt;&gt; a is b False &gt;&gt;&gt; a == b True How to get city name from latitude and longitude coordinates in Google Maps? What is inverse CDF Normal Distribution Formula Plotting two variables as lines using ggplot2 on the same graph I have two files in these formats:   file1 :  air smell hand dude road cat   file 2:   air,4,21,01,13,3,2 smell,21,4,2,5,6 dude,1,31,42,1 road,1,4,2,1,4 cat,1,5,6,3,1 hand,1,4,2,1,6 mouse,1,3,5,6,2   what I want to do is print the entire row of file 2, if the first string in column 1 of file 2 is found in file 1, and I want to keep the order of file 1.   expected output:   air,4,21,01,13,3,2 smell,21,4,2,5,6 hand,1,4,2,1,6 dude,1,31,42,1 road,1,4,2,1,4 cat,1,5,6,3,1 Coordinate-Free Definition of Trace. List manipulation: position & max value combination I'm looking for a short story from about 50 years ago about a robot who escapes after being slated to be melted down and discovers while in hiding that it has evolved to have some supernatural powers. Comment character counter does not trim, while the server does Convert LaTeX to HTML Is there a converter that will convert LaTeX to HTML? I have tried several services but the LaTeX diagrams and some of the maths came out weird.  I actually converted the Latex to PDF without a problem. Then I used  to convert from PDF to HTML. The square root signs did not appear properly and some of the Cartesian coordinate plane diagrams had nothing on them except the grid.   \documentclass[12pt,a4paper]{report} \usepackage{amssymb} \usepackage{amsthm} \usepackage{amsmath} \usepackage{pstricks,pst-plot} \usepackage{pst-eucl} \addtolength{\hoffset}{0.2cm} \addtolength{\textwidth}{1.1cm} \addtolength{\textheight}{1.0cm} \addtolength{\voffset}{-0.7cm} \linespread{1.3} \begin{document}  If $x$ is non-positive then $x \leq -\sqrt{\frac{1}{2}}$     $\hspace{30 mm} $     (6)\\  (4) and (6) tell us that\\  (4)  $-1 \leq x \leq 0$  \\  (6)  If $x$ is non-positive then $x \leq -\sqrt{\frac{1}{2}}$\\  Therefore $-1 \leq x \leq -\sqrt{\frac{1}{2}}$\\  \vspace{50 mm}  \begin{align*} \psgrid[unit=2cm](0,0)(-2,-2)(2,2) \pnode(-1.8,.87){b}\uput[50](b){b} \pnode(-1.8,1.8){a}\uput[50](a){a} \psset{linecolor=green} \psline[linewidth=1pt](-1.8, 0)(-1.8,4) \psset{linecolor=green} \psline[linewidth=1pt](-1.8, 0)(-1.8,-4) \psset{linecolor=blue} \psellipticarc(0,0)(2,2){0}{180} \psset{linecolor=red} \psline[linewidth=1pt,linestyle=dashed,dash=2pt](-2,2)(-1.41,1.41) \psset{linecolor=red} \psline[linewidth=1pt](-1.41,1.41) \psset{linecolor=red} \psline[linewidth=1pt]{-&gt;}(4,-4) \psset{linecolor=red} \psline[linewidth=1pt]{-&gt;}(-2,2)(-4,4) \end{align*}  \end{document}   PDF output:    PDF->HTML output: This is a  about securing public DNS resolvers   Open DNS servers seem pretty neat and convenient, as they provide IP addresses that we can use consistently across our company regardless of where they are located. Google and OpenDNS provide this functionality, but I'm not sure that I want these companies to have access to our DNS queries.  I want to set up something like this for use by our company, but I hear a lot about this being dangerous practice (particularly in regards to ) and I want to make sure that we do this right. What things do I need to keep in mind when building this type of environment? Size of files in Windows OS. (It's KB or kB?) B2B application: users has its own users B2B Scenario I am trying is that:  The following Roles exists in the system:  Super Admin Super Admin Staff Owner (client) Admin (owner i.e. client and creates admin to define sales counters) Sales Counters  That means there are users who'll create their own sub users e.g.  [FLAG-A] ROLE &quot;SUPER ADMIN&quot; creates a ROLE &quot;Owner&quot; and &quot;OWNER&quot; creates its own sub users ROLES i.e. &quot;ADMN&quot; &amp; &quot;SALES COUNTER&quot;. Each role obviously has its info to login to the system I tried to design database as following:  In this diagram I am assuming that main user creates sub user that in my view many to many relationship so I have to add table between them as &quot;USER_PERSON&quot;. Problem is to set &quot;WHO CREATED USER&quot; in the system. I mean which user has created sub user as described in [FLAG-A]  Please check this diagram What are the differences between a pointer variable and a reference variable in C++? I know references are syntactic sugar, so code is easier to read and write. But what is the difference between a pointer variable and a reference variable?
