    - by Tommy
    I'm using just a few basic jQuery functions on my site. How can I remove unused jQuery code? Knowing only the basics, I looked at the code and was not sure where to start. If you could point me in the right direction, that would be appreciated. Thanks.

  • Input/ Output alternatives for printf/scanf

    - by Nitish
    It may sound strange that knowing a lot about ios and haing some experience in .net, I am a newcomer to C. Somewhere I got this target to find average of n numbers without using printf and scanf. I don't want the code for the program but it will be really helpful if someone can help me with the alternatives to the mentioned functions. Please let me know if code with printf/scanf is required here. Also do let me know if my query stands invalid. Thanks and Regards, Nitish

  • Best PHP timezone list

    - by jimbo
    I have looked over the PHP list of supported timezones, but the whole list is a little long to include in a drop-down menu, for the user to select his or her timezone. Is there a list with the main city/area on that can be used? My geography is terrible and add that to not knowing all the area and which timezone they fall into it could be a long day to construct the list my self! Thanks in advance

  • Is it worth investing time in learning low level Java?

    - by Kevin Rave
    Low level Java, I mean, bits, bytes, bit masking, GC internals, JVM stuff, etc in the following contexts: - When you are building an enterprise app using frameworks like Spring, Hybernate, etc. - Interviews for a Sr Java Developer position where you are expected work on a existing Enterprise App that was built using some frameworks (Spring, EJB, Hybernate,etc) - Architects (Java) I understand knowing the very low level is "good". But how often do you think / use of these in the real-world, unless you are developing something from the ground-up keeping performance in mind?

  • Find out what variable is throwing a NullPointerException programatically

    - by Hectoret
    I know I can find out if a variable is null in Java using these techniques: if (var==null) - too much work try { ... } catch (NullPointerException e) { ...} - it tells me what line is throwing the exception using the debugger - by hand, too slow Consider this line of code: if (this.superSL.items.get(name).getSource().compareTo(VIsualShoppingList.Source_EXTRA)==0) { I would like to know if there's a generic way to find out programatically what variable (not just the line) is throwing the NullPointerException in a certain area of code. In the example, knowing that

  • Name that blog entry - Modelling changes over time with two db columns only.

    - by disown
    I vaguely remember reading a blog entry (written by a well-known blogger I think) about how to model price changes over time, and that you could model most changes by saving two dates only (two columns in a db). The blog talked about prices on a website changing over time and how you could figure out the right price to charge knowing only when the purchase had been made. Very vague, I know, but my google-fu is failing me, everyone at IRC are busy talking about other stuff and I don't know what to do! :)

  • Language/Framework support for Interacting With CouchDB

    - by Gordon
    I am interested in knowing if there are any server-side web application frameworks which integrate nicely with CouchDB? Does anyone have any experience in doing this? It seems like a dynamic language would be well-suited for playing with the JSON, but I am more interested in hearing about how it would fit in with the framework and the application's design.

  • Data Access example using Entity Framework

    - by Dan
    Does anyone know of or having any good examples of how to use Entity Framework version 2 in the Data Access layer and put an interface on it so the business layer uses the interface rather than knowing about EF?

  • How much languages is "recommended" for a dynamic website?

    - by user345690
    When constructing a website, say a Q&A site or a just a forum site for a community, is just knowing HTML,CSS,PHP, MySQL, and javascript enough to make the site dynamic? I am saying this because when I talked with my teacher, he said that major sites use many languages combined. And he said that a site shouldn't be designed only in PHP. So is it possible to create a good website, not e-commerce, with only html,css, and php?

  • How do I dynamically reference incremented properties in C#?

    - by Jeff Blankenburg
    I have properties called reel1, reel2, reel3, and reel4. How can I dynamically reference these properties by just passing an integer (1-4) to my method? Specifically, I am looking for how to get an object reference without knowing the name of the object. In Javascript, I would do: temp = eval("reel" + tempInt); and temp would be equal to reel1, the object. Can't seem to figure this simple concept out in C#.
