How do I install ndiswrapper support for an unsupported RTL8723DE wireless module? Example of mailmerge package with an Excel spreadsheet I am looking for an example for using the  package to write a cover letter, with names and addresses on a spreadsheet. The package comes with an example, but you have to manually enter all the data. Right so seeing as the new Deadpool movie shows the origins of Deadpool: specifically, he got cancer... blah blah had to get him the healing factor from Wolverine.  But that makes no sense — they used the same actor, so I'm assuming there must be some connection, right... right? The timeout period elapsed prior to obtaining a connection from the pool I'm getting this error every few days. I won't see the error for a few days then I'll get a flurry of 20 or so all with in a minute or so.  I've been very thorough going throw my code so that I'm using this basic setup for my DB access.  try {   myConnection.Open();   mySqlDataAdapter.Fill(myDataTable);   myConnection.Close(); } Catch (Exception err) {   if (myConnection.State != ConnectionState.Closed) myConnection.Close();   throw err; }   The way I understand it this should execute my queries and immediately release the connection back to the pool but if something goes wrong with the query then I catch the excpetion close my connection then throw the error up, which eventually gets trapped at the application level and logs and emails me the error.  Even using this throughout my code I'm still running across the issue. What can I do to diagnose the root cause of the issue? we are currently experiencing some issues with the ambiguity feature of apa for biblatex/biber (we use biber) in TexLive 2012.

How to evaluate the limit $\lim_{x\to 0} \frac{1-\cos(4x)}{\sin^2(7x)}$ If I play a spell with {X} in the mana cost, and I have a card out that reduces the casting cost by 2 generic mana, what happens to the X? Does it start at -2?  For example: I have  in play. If I play  for just 1 blue mana, do we draw 2 cards? Negative logLikelihood Kalman filter How does \fontsize{}{} work? Solve $x^2+2=y^3$ using infinite descent? I have created a VF page and used "render as pdf"  &lt;apex:commandButton value="Save to Opportunity" action="{!savePdf}"  /&gt;   Its working fine when i am using above line without rerender and oncomplete but when i am adding rerender or oncomplete it is not working.I am able to save the PDF in attachment folder but when i am trying to open its showing  "Unable to load document"  Even if i remove oncomplete and use Rerender then also its saving the attachment in Attachment object and when i view ,it is not loading and says "Unable to load document"      &lt;apex:commandButton value="Save to Opportunity" action="{!savePdf}"  oncomplete="myClose();"/&gt;   Javascript Code  function myClose(){      self.close();     window.opener.location.href="/{!$CurrentPage.parameters.Id}";  }   Class Code  public void savePdf() {      PageReference pdf = Page.GenerateQuotePDF;     pdf.getParameters().put('id',parentId);      Attachment attach = new Attachment();      Blob body;     body = pdf.getContent();     attach.Body = body;     attach.Name = 'Opportunity'+ '.pdf';       attach.IsPrivate = false;     attach.ParentId = parentId;     attach.ContentType = 'application/pdf';     insert attach;     }     Please help.. Youtube says "This video is currently unavailable" Is there a Term to describe the relationship between two people when they share an Alma Mater?  For example; Neil Armstrong is an alumnus of Purdue University. I am an alumnus of Purdue University. Both Neil and I are alumni of Purdue University, which is to say we share an alma mater. So, I'm looking for a term to describe my relationship to to Neil with out needing to explicitly reference the university. Is co-alumni a real term? Is it appropriate to say that Neil and I are co-alumni? Is there something better? Further, is there a way to specifically describe the relationship between two people from the same graduating class?  Thank You in advance! Why are my converted CMYK blacks coming out grey? I'm having a rather annoying problem! I have RGB images made in Photoshop that I need to convert to CMYK.  When I save the file my black background is converted to a light grey! I tried deleting my background and adding a pure black background in my PSD file but even that comes out grey! There is no way to save black? The colors all look fine in Photoshop, it's just when I save them as TIFF/JPEG.  How can I prevent this? $$ 3x+6y+5z=7 $$ The general solution to this linear Diophantine equation is as described    $$ x = 5k+2l+14 $$ $$ y = -l $$ $$ z = -7-k $$ $$ k,l \in \mathbb{Z} $$  If I plug the original equation into  the solution is: $$ y = 5n+2x+2  $$ $$ z =-6n-3x-1 $$ $$ n \in \mathbb{Z} $$  I can rewrite this as:  $$ x = l $$ $$ y = 5k+2l+2 $$ $$ z = -6k-3l-1 $$ $$ k,l \in \mathbb{Z} $$  However now two equations depend on two variables ($k,l$) and one on one variable $l$. In the first solution one equation depends on two variables and two on one variable.  Questions:  How can I come from a representation like the one from wolfram alpha for the general solution to one where all equations depend on one distinct variable except one equation.  Is there always such a representation? For example, this regex  (.*)&lt;FooBar&gt;   will match:  abcde&lt;FooBar&gt;   But how do I get it to match across multiple lines?  abcde fghij&lt;FooBar&gt; Suppose $f: \mathbb{R} \to \mathbb{R}$ is a continuous function which is 1-1, then does $f$ map Borel sets onto Borel sets? How to Check If A Plugin Is Enabled Through API? This is what my GRUB 2 menu looks like so far:  I want to do a few things here:  I want to rename &quot;Windows Boot Manager (on /dev/sda1)&quot; to just &quot;Windows 8.1&quot;. I'd like to rename &quot;Ubuntu&quot; to &quot;Lubuntu 14.04.1&quot;. I'd also like to switch the order of the options to this:  Windows 8.1 Lubuntu 14.04.1 Advanced options for Lubuntu    (Windows will be the default OS) If it helps in any way, I'll explain the steps I took prior to this, since I am very new to Linux and don't know what information is required.  I bought a laptop on Amazon (ASUS X551MAV-EB01-B) pre-installed with Windows 8.1 64-bit I downloaded the proper Lubuntu .iso file for my system (Lubuntu 14.04.1 amd64) and put it on my flash drive (via UNetBootin) I went to Disk Management, and shrunk the C:/ drive down 32Gb so that 32Gb will be free for Lubuntu I used my flash drive (32Gb Sandisk Cruzer) as a LiveUSB for Lubuntu 14.04.1 I went through the install process. It didn't recognize Windows 8.1 so I had to do the &quot;Something Else&quot; option. I highlighted the free space, and pressed the + button I created a 10,000mb ext4 partition and mount point is / (is now dev/sda7) I created a 4,000mb swap area partition (is now dev/sda8) I created an ext4 partition using the rest of the free space and the mount point is /home (is now dev/sda9) I selected dev/sda7 to install Lubuntu and selected dev/sda7 for the bootloader installation It installed just fine, booted up just fine, and I'm happy to know the GRUB menu works. I have a list of structs and I want to change one element. For example :  MyList.Add(new MyStruct("john"); MyList.Add(new MyStruct("peter");   Now I want to change one element:  MyList[1].Name = "bob"   However, whenever I try and do this I get the following error:     Cannot modify the return value of   System.Collections.Generic.List.this[int]‘ because it is not   a variable   If I use a list of classes, the problem doesn't occur.  I guess the answer has to do with structs being a value type.  So, if I have a list of structs should I treat them as read-only? If I need to change elements in a list then I should use classes and not structs?
