• What is the simplest way to implement an instant messaging contact page on my website?

  I'd like to have a page that communicates directly to some IM service that I will generally be able to be logged into. E.g. I am on gtalk all the time, I'd like people to be able to get in touch with me via the website. (the specific protocol isn't that important, of course) What would be the simplest set of technologies to implement that?

• 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?

• Database Formatting for Album Tracks

  - by Sev

  I would like to store album's track names in a single field in a database. The number of tracks are arbitrary for each album. Each album is one record in the table. Each track must be linked to a specific URL which also should be stored in the database somewhere. Is it possible to do this by storing them in a single field, or is a relational table for the track names/urls the only way to go?

• Windows Application Data Directory

  - by JP

  Not completely a programming question, but its close enough so here goes: In Mac OS I'll put user-specific files for my app in ~/Library/Application Data/{MyApp}/ and in *nix I'll put them in ~/.{MyApp}/ - where should I put them for Windows? I'll be using Ruby's File.expand_path to get to this directory, so if there's a windows equivalent of ~ then that's fine. (Answers for Windows XP, Vista and 7 would be appreciated if they're not the same)

Thanks!

• PHP: Check if it has been one week since timestamp

  - by Rudi

  Hi guys, Let's assume: $time = '2010-05-17 02:49:30' // (retrieved from MySQL TIMESTAMP field) How do I do the following in PHP: 1) Check if it has been more than one week since this time has passed? 2) Assuming "false" on (1), find out how much more time until the one week mark, rounded to days and hours remaining. I know this is pretty straightforward, but it uses a very specific syntax. Having never played with time calculations before, I'd appreciate some guidance. Thanks!

• jQuery .eq(x) returns different element in IE than in FF/Chrome

  - by bt

  I am using the .eq() method to select a specific child element of a known element. It appears that the element indices are different in IE and in Chrome/FF, as .eq(2) returns different values depending on browser. (The element I'm looking for shows up as .eq(2) in FF/Chrome, but .eq(3) in IE) For example, alert($(this).parent().children().eq(2).text()); shows different results depending on the browser. Is there a better way of doing this?
