• php joomla session lifetime settings

  - by jtanmay

  I have searched through the google and also joomla forums but didn't got what exactly I was looking for. My main purpose is to set the joomla session live for ever. Many forums says its not good to keep a higher value (security issues) but I don't want to consider that right now. My question is : What if I set the session lifetime value to "0" (Zero), will the session be active for ever? or the user will NOT be able to login completely? Thanks, Tanmay

• Regex vs. string:find() for simple word boundary

  - by user576267

  Say I only need to find out whether a line read from a file contains a word from a finite set of words. One way of doing this is to use a regex like this: .*\y(good|better|best)\y.* Another way of accomplishing this is using a pseudo code like this: if ( (readLine.find("good") != string::npos) || (readLine.find("better") != string::npos) || (readLine.find("best") != string::npos) ) { // line contains a word from a finite set of words. } Which way will have better performance? (i.e. speed and CPU utilization)

• CSS - How can I center a div within a div?

  - by Spines

  I have an outer div that is 800px wide. I have an inner div that could be anywhere from 200 to 600px wide. I know how to center the inner div within the outer one if I set the inner one to have a specific width, but how do I center it since its a variable width? Is there a way to set the div to only be the width of the elements inside of it, rather than having it expand to fill its containing div?

• Better alternative for PipedReader/PipedWriter?

  - by Esko Luontola

  I need to have a buffered char stream, into which I write in one thread and from which I read in another thread. Right now I'm using PipedReader and PipedWriter for it, but those classes cause a performance problem: PipedReader does a wait(1000) when its internal buffer is empty, which causes my application to lag visibly. Would there be some library which does the same thing as PipedReader/PipedWriter, but with better performance? Or will I have to implement my own wheels?

• Business Units vs Teams in CRM 2011

  - by GuruJ

  I've been told a few times that Business Units in CRM 2011 are "tricky" and shouldn't be set up lightly since they have irreversible consequences for a CRM 2011 implementation. On the other hand, teams in CRM 2011 seem much more flexible in managing record security. For what reason would I still choose to set up Business Units in CRM 2011? What can I do with Business Units that I can't with Teams (and vice versa)?

• Changing the block size of a dfs file in Hadoop

  - by Sam

  I found that my map tasks is currently inefficient when parsing one particular set of files (total 2 TB). I'd like to change the block size of files in the Hadoop dfs (from 64MB to 128 MB). I can't find how to do it in the documentation for only one set of files and not the entire cluster, does anyone know the command that would change the block size when I upload it (ie copy from local to the dfs)? Thanks!

• Increase the length of Xcode's "recent project" list?

  - by Bogatyr

  I switch in Xcode between working on a lot of different projects frequently (some I'm actively working on, some are old projects where I'm looking up code I want to re-use or quote in SO answers :)), so that part of my "working set" of projects invariably ends up falling off the recent project list. I do use finder tabs for the full working set of current project folders, but I really like the fast switching available using the recent projects list. Is there a way to increase the length of this list so that I can see more recently opened projects?

• Hibernate (JPA) Entity with Static collection as a member

  - by Kyle Partridge

  Is it possible to have a static collection as a member of a hibernate entity? Say I have an object Question: public class Question { private String category; ... } Would it be possible to populate a static Set<String> that is a distinct set of all categories in the Database? I know I could just query this, but I was wondering if there was a more elegant solution, as it seems like something that other people may have come across.
