What is the process of turning HTML into Postscript programmatically
- by Dean
I am trying to understand what the process is of turning HTML into a PDF/Postscript programmatically All Google searches turn up libraries to do this, but I am more interested in the actual process required. I know you could just set up a Postscript printer and print directly to that, but some of these libraries appear to create the PDF on the fly to allow previews etc. has anyone had any experience in this, or can provide any guidance?Read the article

Cakephp Auth Flash Messages losing style
- by Michael
My Auth flash messages were working earlier -- a bright green background with text in it, such as "You have successfully logged out". However, I have made quite a few changes to the site since then, and this green background has disappeared. What are the possible causes of this? (I've run my CSS through a validator -- so that doesn't seem to be the issue). Any other ideas? Thanks!Read the article

Emacs How to redefine Shift-R for expected use
- by John Bellone
I've checked my elisp files to make sure that I do not have any bindings that contain Shift+R (and I have not found any). I expect SHIFT+R to print an uppercase character, but instead I get R R undefined inside of the Emacs command line. This is only in C/C++ major modes. Any suggestions? Update: Describing the key shows that it is undefined. How would I define it for the normal, expected use (capitalizing the letter R)?Read the article

Find last match with python regular expression
- by SDD
I wanto to match the last occurence of a simple pattern in a string, e.g. list = re.findall(r"\w+ AAAA \w+", "foo bar AAAA foo2 AAAA bar2) print "last match: ", list[len(list)-1] however, if the string is very long, a huge list of matches is generated. Is there a more direct way to match the second occurence of "AAAA" or should I use this workaround?Read the article

Error handling in the RequestHandler without embedding in URI
- by hyn
When a user sends a filled form, I want to print an error message in case there is an input error. One of the GAE sample codes does this by embedding the error message in the URI. Inside the form handler (get): self.redirect('/compose?error_message=%s' % message) and in the handler (get) of redirected URI, gets the message from request: values = { 'error_message': self.request.get('error_message'), ... Is there a way to accomplish the same without embedding the message in the URI?Read the article

How to calculate the maximum block length in C of a binary number
- by user1664272
I want to reiterate the fact that I am not asking for direct code to my problem rather than wanting information on how to reach that solution. I asked a problem earlier about counting specific integers in binary code. Now I would like to ask how one comes about counting the maximum block length within binary code. I honestly just want to know where to get started and what exactly the question means by writing code to figure out the "Maximum block length" of an inputted integers binary representation. Ex: Input 456 Output: 111001000 Number of 1's: 4 Maximum Block Length: ? Here is my code so far for reference if you need to see where I'm coming from. #include <stdio.h> int main(void) { int integer; // number to be entered by user int i, b, n; unsigned int ones; printf("Please type in a decimal integer\n"); // prompt fflush(stdout); scanf("%d", &integer); // read an integer if(integer < 0) { printf("Input value is negative!"); // if integer is less than fflush(stdout); return; // zero, print statement } else{ printf("Binary Representation:\n", integer); fflush(stdout);} //if integer is greater than zero, print statement for(i = 31; i >= 0; --i) //code to convert inputted integer to binary form { b = integer >> i; if(b&1){ printf("1"); fflush(stdout); } else{ printf("0"); fflush(stdout); } } printf("\n"); fflush(stdout); ones = 0; //empty value to store how many 1's are in binary code while(integer) //while loop to count number of 1's within binary code { ++ones; integer &= integer - 1; } printf("Number of 1's in Binary Representation: %d\n", ones); // prints number fflush(stdout); //of ones in binary code printf("Maximum Block Length: \n"); fflush(stdout); printf("\n"); fflush(stdout); return 0; }//end function mainRead the article
