Is there a simple command one can put in the preamble to treat all blank pages like empty pages (with no page number and no header)?
To ensure that a new chapter starts on a right-hand page, the book class (and the report class with the options twoside and openright) will insert blank pages between chapters if necessary. However, these pages still contain the headers and footers as defined by the class. How can I remove those?  Note: I know that I can manually add \clearpage\thispagestyle{empty} at the appropriate points of my document. However, this seems awkward and is prone to fail if I change my document later. I'm looking for automatic solutions.
Reputation has been changed but not reflected on tooltip. Difference between $:=$ and $=$ I am sorry if this is quite elementary question. But I always think, that why we use $:=$ at some places, instead of $=$. Is there any fundamental difference between these two? Before reading Terry Tao's blog (4 months ago), I had never seen a symbol like this (:=). Footnote, non-inline syntax? I would like to use footnotes without cluttering the container paragraph. Something like:  This is a very long complex\footnote[a] sentence.  \foottext[a]{So complex that I would prefer to pull out the footnote text.}   The idea comes from the [linktext][1], [1]: http://url.com markdown syntax. Does anyone know of a simple Image Editor, with functionality comparable to ,  for Ubuntu?  I've always found GIMP to be overkill and too complicated for what I want to do. Why does Microsoft Word 2010 show an error for the following sentence?     1.&nbsp;Where should this car be parked?   Word 2010 also suggests changing the sentence to     2.&nbsp;Where this car should be parked?   Is the sentence (1) wrong? If yes, why? What about sentence (2)? Get all non-unique values (i.e.: duplicate/more than one occurrence) in an array SF TV show about a war between humans and aliens? What's the best way to take a segment out of a text file? When is it best to write "can't" versus writing "cannot"? Are they interchangeable in every situation? I would like to find a Python script that will access an attribute table within a shapefile and either update or replace records inside a field column. More specifically, I would like to use the replace expression to convert a table record like "123-456-789" to "123456789". I have many records to process and would like the best approach to do this task using Python. Using thematic layer for segmentation in eCognition? I have a thematic layer, i want to perform segmentation and classification only within the thematic layer,not in a whole image. how can i do it? I tried to segment the image after viewing the thematic layer in view setting and the thematic layer usage was enabled, but it was segmenting the whole image. I found that every character has a "Personal Item" in his inventory after you start the game. My question is: What is the purpose of it? I mean yeah you could sell it for 100$ but that really is absolutely nothing. It also doesn't have any stats so what can I use it for? What are the limits on how I can cast, change, and retract votes? What should main() return in C and C++? Reading about  I understood that black holes lose energy over time - which is logical in some way (otherwise they would be there forever and heat death would never technically happen)  But - how exactly does it "evaporate"? What happens when it no longer contains enough mass within it's  ? Does it explode somehow? Transforms into "regular matter"? Simply vanishes over time? Or? Triggering actions when a variable is set How do I define solar irradiance in the context of a solar cell? This is homework. I've tried my best to find the best answer that I could understand and could be accepted by my lecturer.   I've searched my lecture notes, wiki and google to find some good explanation defining solar irradiance. But somehow I still don't understand how I should 'define solar irradiance'. Can someone give me a few good sentences explaining solar irradiance. What are the changes, if any, in a photovoltaic cell (in terms of short-circuit current and open-circuit voltage) if the irradiance is reduced by 50%? How do I disable notifications in my personal profile for activity on pages I am an admin of? I'm an admin of several pages on Facebook (for technical stuff like RSS imports, etc.), but neither do I contribute content nor do I care about their content.  Still, as an admin, I get notifications (upper left hand, the globe icon) about activity (someone liked this, someone posted that) on those pages in my personal (!) profile .  Does anyone have the same issue? Is there any way to explicitly disable notifications for certain pages?  (This behavior seems to be new, by the way; I'm only seeing those notifications for a few weeks now.) Include chapters in List of Figures with titletoc? I was trying to understand the internal structure of AES (Advanced Encryption Standard)  The Standard order of steps within a round:   Substitute Bytes Shift Rows Mix Columns Add Round Key   Substitute Bytes, Shift Rows &amp; Mix Columns satisfies the two most important properties required for a secure cipher i.e confusion and diffusion   Substitute Bytes provides Confusion i.e. that each binary digit (bit) of the ciphertext should depend on several parts of the key.  Shift Rows along with Mix Column provides Diffusion i.e. if we change a single bit of the plaintext, then (statistically) half of the bits in the ciphertext should change  Changing the order of Step 1 and Step 2 won't have any effect. But to what extent can we change the order of other steps? Does it weakens the security of AES, and if so, how?
