Warning: mysql_fetch_* expects parameter 1 to be resource, boolean given error Good reading on the Keldysh formalism I'd like some suggestions for good reading materials on the Keldysh formalism in the condensed matter physics community. I'm familiar with the imaginary time, coherent state, and path integral formalisms, but lately, I've been seeing Keldysh more and more in papers. My understanding is that it is superior to the imaginary time formalism at least in that one can evaluate non-equilibrium expectations. Data extension values in the "Update Contact" activity in Journey Builder I'm looking for a way to use fields from a data extension (that is the entry source for a journey) in the "Update Contact" activity.  I want to create a sort of log in a different data extension. Let's say I have a sourceDEthat is used by the journey and a journeylogDE where I would like to write the email of contact that's currently in the journey.  What should I write in the value field to get a value from the currently used record in the sourceDE?  I tried {{Contact.Attribute.sourceDE.email}}, but it did not return any values.   I would appreciate it if you could give me any tips how to fix this issue. My issue is that I have a blender file in which cameras and lamps do not move when I attempt to rotate them using the mouse. If I select the objects (in object mode), press R, and move the mouse in the viewport, the lamps and cameras don't respond; they remain in the same orientation as when I started, no matter how vigorously I try to move the mouse. The values in the information bar show that the mouse is communicating. If, however, I manually enter a new value for the amount of rotation in the properties shelf of the viewport, the camera moves to the new orientation.  On a new default Blender scene, the cameras and lamps do respond to commands to rotate and scale using the mouse. I've compared all of the settings I can think of, and don't see anything obvious that corrects the problem.   is available. How to determine callee function name in a script To make it short, doing something like:  -bash$ function tt {  echo $0; }  -bash$ tt   $0 will return -bash, but how to get the function name called, i.e. tt in this example instead? Is it possible to downgrade an OEM Windows 8 install to Windows 7? I recently purchased an ASUS K55A. Like all Windows 8 machines, it come with a UEFI feature called Secure Boot. This basically makes sure that the laptop won't load anything other than the Windows 8 OEM version that came with it.  However the Asus UEFI allows for me to disable Secure Boot, and therefore I should be able to revert to Windows 7, Linux, etc. (drivers may or may not be supported). When I insert my Linux Mint boot disc and try to boot from it, though, nothing happens. There isn't even a boot priority list in the UEFI settings (I can provide screenshots later). It just says "Windows 8 Bootloader" and also on the other tab it says "WINDOWS 8 BOOT OVERRIDE".  Has anybody purchased a Windows 8 machine and successfully installed Windows 7 or Linux on it? Making images from single.php pointing to an attachment .php template In a Poisson model, what is the difference between using time as a covariate or an offset? I recently discovered how to model exposures over time using the log of (e.g.) time as an offset in a Poisson regression.  I understood that the offset corresponds to having time as covariate with coefficient 1.  I'd like to better understand the difference between using time as an offset or as a normal covariate (therefore estimating the coefficient). In which situation should I want to use one method or the other?  UPGRADE: I don't know if it is interesting, but I ran a validation of the two methods using randomly split data repeated 500 times and I noticed that using the offset method leads to a larger test error. Relating the union of the power set of a set to the set itself Variable declaration placement in C I long thought that in C, all variables had to be declared at the beginning of the function. I know that in C99, the rules are the same as in C++, but what are the variable declaration placement rules for C89/ANSI C?  The following code compiles successfully with gcc -std=c89 and gcc -ansi:  #include &lt;stdio.h&gt; int main() {     int i;     for (i = 0; i &lt; 10; i++) {         char c = (i % 95) + 32;         printf("%i: %c\n", i, c);         char *s;         s = "some string";         puts(s);     }     return 0; }   Shouldn't the declarations of c and s cause an error in C89/ANSI mode? How does \fontsize{}{} work? With the package anyfontsize I can use the command \fontsize{}{}. But the second argument seems to be without any effect. I read  that it is related to the line space. It doesn't work.  \documentclass{article} \usepackage{anyfontsize} \begin{document}  {\fontsize{1cm}{1cm}\selectfont First test : I need to put some text here.}  \bigskip  {\fontsize{1cm}{2cm}\selectfont Second test : I need to put some text here --- does it work?}  \end{document}     Any clue? Why does the area of a bar in a histogram represent the frequency of that particular class In a bar-graph, the height of the bars represent the frequency of a particular category but it is counter-intuitive that in a histogram, instead of the height of the bar(which represents the frequency density), the area of the bar represents the frequency of the particular class.

How to show (or hide) a hidden file I wanted to add classpath to my JDK. While searching a way to do it I noticed everyone open .profile file using terminal. But when I want to open and edit it with a text editor I couldn't see that file in Home folder.  Can someone tell me why is this. And also if possible how can I access .profile in home folder the GUI way.
