  • Not very objective - please help

    - by chainwork
    I am having trouble understanding the meaning and more importantly the concept of an object as it relates to jQuery. I understand the basics that its a collection of data that comes in two forms, properties and methods but I kind of get lost on how it works beyond that. Can anyone point me to some good tutorials that maybe helped you understand? I'm hoping to "Get it" once and for all. Many many thanks for your help! =]

  • Setting a ListView Divider in code

    - by deSelby
    One of my ListView's needs to be created in code. When I specify a ListView in xml, I can set a dividerHeight and assign a color to the divider. But apparently, in code a color is not acceptable nor is pointing to a resource id. Only a Drawable is acceptable - and I haven't gotten to that chapter yet. Can someone point me to an example of setting a ListView divider in code?

  • Erlang: What are the pros and cons of different methods for avoiding intermediate variables?

    - by erlacher
    At one point while traveling the web, I came across a great page which contrasted the clarity and terseness of different methods of doing a sequence of operations without having to make a bunch of throwaway variables, e.g., Var1, Var2, Var3. It tried list comprehensions, folds, maps, etc. For some reason, now matter what I google, I can't find it again. Anyone have any idea what I'm talking about? Or want to explore the topic anyway?

    So I am looking for a nice list of NHibernate events that actually describes when they are fired, in a typical scenario. IE something like PreUpdateEventListener - Fires when an object that is already persistent is changing I currently just rifle through the source and try to figure it out, but it's kinda painful, and I figure that someone must have done this already at some point.

  • Remove results below a certain score threshold in Solr/Lucene?

    - by snickernet
    Hi Guys, Is there a built-in functionalities in solr/lucene to filter the results if they fall below a certain score threshold? Let's say if I provide a score threshold of .2, then all documents with score less than .2 will be removed from my results. My intuition is that this is possible by updating/customizing solr or lucene. Could you point me to right direction on how to do this? Thanks in advance!

  • Is an editable select box the right way?

    - by Neil Middleton
    I have a scenario where a user is emailing another user in an HTML based web app. For the To: field, the user may select one of a pre-defined list of emails OR enter their own ignoring the pre-defined options. What would be the best way of doing this from a UI point of view? I've looked at editable select boxes using jQuery but none seem to let you enter your own option. Is there some other UI mechanism that would work here?

  • How computer multiplies 2 numbers?

    - by ckv
    How does a computer perform a multiplication on 2 numbers say 100 * 55. My guess was that the computer did repeated addition to achieve multiplication. Of course this could be the case for integer numbers. However for floating point numbers there must be some other logic. Note: This was asked in an interview.

    Hey guys I'm very new to the whole programming - so far I only have experience with building websites, database etc. I currently have a website where users can share their online purchases.

  • Save list of CGPoints using NSUserDefaults

    - by Chris Daviduik
    I have a bunch of CGPoints from a CCTMXLayer I want to save to NSUserDefaults but cannot seem to figure out an elegant way of doing so. Originally I was hoping to save an NSDictionary with an NSMutableSet for a value containing several NSValues (valueWithCGPoint). From what I can tell neither NSMutableSet or NSValue is supported by NSUserDefaults. At this point I am considering saving the x&y values of the CGPoint as a string and just converting it back and forth as needed.
