  • What is the difference between JSON and Object Literal Notation?

    - by burak ozdogan
    Hi, Can someone tell me what is the main difference between a Javascript object defined by using "Object Literal Notation" and JSON object? According to a Javascript book it says this is an object defined by using Object Notation: var newObject = { prop1 : true, showMessage : function (msg) {alert(msg)} }; Why it is not a JSON object in this case? Just because it is not defined by using quotation marks? Thanks,

  • Books or resources for high-loaded sites.

    - by Alex
    Currently I'm developing high-loaded financial portal(we use LAMP to run our project). There are great number of incoming data to be processed and stored. So optimization tasks become very important for us. Could you suggest books, articles or resources, that discover optimization questions (especially bboks). NOTE: At the moment I'm reading great book High Performance MySQL, but besides I want to know other facilities of optimization.

  • Windows programming for Unix programmer

    - by Jochen Walter
    I am looking for an introduction to Windows programming. I already have some experience with .net-programming using C#, now I want an overview of the lower-level APIs of Windows. Wikipedia has an article on this subject but, it is quite terse. Is there a canonical book or web site for this kind of information?

  • Can't find ant in the Android SDK

    - by StormShadow
    Hey all, I'm working my way through APress's Beginning Android 2 and I've made it all the way to chapter 3, where we build a skeleton app. The book tells me to compile my application by typing "ant" in the command line, but my pc doesn't know what "ant" is yet. I checked in the SDK files and it looks like it wasn't included with the Android SDK. Does anybody know where ant is? Thanks

  • scala for yield setting a value

    - by coubeatczech
    Hi, I want to create a list of GridBagPanel.Constraints. I read it in the scala programming book, that there is a cool for-yield construction, but I probably haven't understood the way it works correctly, because my code doesn't compile. Here it is: val d = for { i <- 0 until 4 j <- 0 until 4 } yield { c = new Constraints c.gridx = j c.gridy = i } I want to generate a List[Constraints] and for every constraint set different x,y values so later, when I later add the components, they're going to be in a grid.

  • What are the BEST resources for learning WPF & .NET?

    - by dicroce
    I'm a longtime C/C++ Unix guy. I recently started work in a new position that's gonna eventually require C# and WPF (and probably some LINQ). What are the best resources to quickly come up to speed on all these Microsoft technologies? Years ago I read Petzold's book and loved it because it was so complete and by the end I really felt like I knew what I was doing... Is their something equivalent for the .NET world?

  • Can one use polygon() or equivalent in lattice and ggplot2 plots?

    - by Alex Reynolds
    Is it possible to annotate lattice (or ggplot2) figures with elements created with polygon() (or elements created with a similar function) from the graphics library? I'm not too familiar with either library beyond examples of simple graphs posted on the web and printed in Deepayan Sarkar's book. Therefore, while I have code for what I've been doing in R with the graphics library, pointing me to relevant, equivalent functions and usage examples for lattice or ggplot2 specifically would be appreciated. Thanks.

  • Is there a /users/www-data type directory in RedHat/Fedora?

    - by Yarin
    I'm trying to setup web2py on my Fedora server, and the instructions, written for Debian, are telling me to install it in the /users/www-data directory. I realize that Fedora uses a default 'apache' user for running Apache, and Debian uses a 'www-data' user, but there's no corresponding /users/apache directory on my machine... Here are the instructions http://web2py.com/book/default/section/11/2
