  • Is it possible to use AWS as a web host?

    - by Matrym
    Is it possible to load / host an entire website using AWS? Or is it only a service that can load specific pieces of a website - such as images, etc. Obviously, I'd want to use my own domain. If you can use it, are there any limitations? Here's the AWS link, for context: http://aws.amazon.com/s3/

  • Setting log level of message at runtime in slf4j

    - by scompt.com
    When using log4j, the Logger.log(Priority p, Object message) method is available and can be used to log a message at a log level determined at runtime. We're using this fact and this tip to redirect stderr to a logger at a specific log level. slf4j doesn't have a generic log() method that I can find. Does that mean there's no way to implement the above?

  • Millions of 3D points: How to find the 10 of them closest to a given point?

    - by Kazoom
    A point in 3-d is defined by (x,y,z). Distance d between any two points (X,Y,Z) and (x,y,z) is d= Sqrt[(X-x)^2 + (Y-y)^2 + (Z-z)^2]. Now there are a million entries in a file, each entry is some point in space, in no specific order. Given any point (a,b,c) find the nearest 10 points to it. How would you store the million points and how would you retrieve those 10 points from that data structure.

  • Bind DataGrid to Dictionary in ASP.NET

    - by mcoolbeth
    In ASP.NET, binding a DataGrid to a list of objects is super-easy. I end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object. However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key? Thanks.

  • How do you keep track of your thought process ?

    - by Johnny Blaze
    I find it very hard to answer question like : "why did you implemented it this way?" or "what's the reason of using that instead of that?" usually because the implementation is the result of a long thought process and trials and errors. By the time i'm finished i can't recall every specific details. I wanted to know if you have some tips to keep track of your thought process and answer those question easily.

  • Multiple views and source list in a Core Data app

    - by Ellie P.
    I'm working on my first major Cocoa app for an undergraduate research project. The application is document-based and uses Core Data. One of the entities is an abstract entity, Page. Page is parent of several types of pages: ie PageWithHeaderAndFooter, PageWithTwoColumns, BasicPage etc. Page has attributes, such as title and author, that all pages have in common. Each specific type of page has a certain number of layout blocks (PageWithHeaderAndFooter has three: header, footer, body. BasicPage has one: body. etc.) Additionally, all Page subclasses define layout-specific implementations of certain methods. The other relevant entity is Style, which defines the visual look of a Page. (Think of Pages as HTML and Style as CSS.) I would like my app to have an iTunes/Mail-like source list with sections. (One section would be Pages, the other would be Styles.) I have a pretty good idea how to do the sectioned source list (this was a great help). However, after hours of headbanging and fruitless googling, here's what I can't figure out: Pages and Styles listed in the source list, and when you select one of them, all of the relevant fields for that object appear at the right (mostly NSTextViews, pop up menus, etc). I laid that out and did all of the bindings in Interface Builder. The problem is, if my source list contains different types of pages, how do I get a different view to display at the right depending on the type of page selected? For example, if a BasicPage is selected, I want just what you see above: the general page stuff and one NSTextView that corresponds to the one field body of BasicPage. But if I select a PageWithHeaderAndFooter, I want to display the general page stuff plus three NSTextViews (one for header, body, and footer.) If I have a Style selected, I want to display various pop up menus, color wells, etc. For the pages at least, we're only talking about one or more NSTextViews, each of which corresponds to a String attribute of the respective entity. How would you do this? Thank you for your help!

  • Erlang programming exercises

    - by valya
    I'm learning Erlang. I've moved from Haskell so I don't want to and have to learn functional programming. But Erlang is quite specific because of the microprocesses. So, can you give me some examples which will be simple to test and measure and use all the power of Erlang?

  • String literals vs constants for Session[...] dictionary keys

    - by FreshCode
    Session[Constant] vs Session["String Literal"] Performance I'm retrieving user-specific data like ViewData["CartItems"] = Session["CartItems"]; with a string literal for keys on every request. Should I be using constants for this? If yes, how should I go about implementing frequently used string literals and will it significantly affect performance on a high-traffic site? Related question does not address ASP.NET MVC or Session.

  • Control parent must be X

    - by Shawn Mclean
    In silverlight, how do I create a usercontrol whose parent must be of a specific control? Eg. I create control Foo, Foo can only be a child of control FooParent. If in blend, they drag it to inside anything except for a FooParent control, it throws error. Foo should then be able to access properties and public methods of FooParent. Is there an official way to accomplish this?

    - by srk
    I need to disable the Mouse Clicks, Mouse movement for a specific windows for a Kiosk application. Is it Feasible in C# ? I have removed the menu bar and title bar of a specific window, will that be a starting point to achieve the above requirement ? How can i achieve this requirement. The code for removing the menu bar and title bar using window handle : #region Constants //Finds a window by class name [DllImport("USER32.DLL")] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); //Sets a window to be a child window of another window [DllImport("USER32.DLL")] public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); //Sets window attributes [DllImport("USER32.DLL")] public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); //Gets window attributes [DllImport("USER32.DLL")] public static extern int GetWindowLong(IntPtr hWnd, int nIndex); [DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)] static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName); [DllImport("user32.dll")] static extern IntPtr GetMenu(IntPtr hWnd); [DllImport("user32.dll")] static extern int GetMenuItemCount(IntPtr hMenu); [DllImport("user32.dll")] static extern bool DrawMenuBar(IntPtr hWnd); [DllImport("user32.dll")] static extern bool RemoveMenu(IntPtr hMenu, uint uPosition, uint uFlags); //assorted constants needed public static uint MF_BYPOSITION = 0x400; public static uint MF_REMOVE = 0x1000; public static int GWL_STYLE = -16; public static int WS_CHILD = 0x40000000; //child window public static int WS_BORDER = 0x00800000; //window with border public static int WS_DLGFRAME = 0x00400000; //window with double border but no title public static int WS_CAPTION = WS_BORDER | WS_DLGFRAME; //window with a title bar public static int WS_SYSMENU = 0x00080000; //window menu #endregion public static void WindowsReStyle() { Process[] Procs = Process.GetProcesses(); foreach (Process proc in Procs) { if (proc.ProcessName.StartsWith("notepad")) { IntPtr pFoundWindow = proc.MainWindowHandle; int style = GetWindowLong(pFoundWindow, GWL_STYLE); //get menu IntPtr HMENU = GetMenu(proc.MainWindowHandle); //get item count int count = GetMenuItemCount(HMENU); //loop & remove for (int i = 0; i < count; i++) RemoveMenu(HMENU, 0, (MF_BYPOSITION | MF_REMOVE)); //force a redraw DrawMenuBar(proc.MainWindowHandle); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_SYSMENU)); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_CAPTION)); } } }

  • lucene index missing files

    - by Akhil
    I have _0.cfs file of a lucene index directory but segments.gen and segments_2 are missing. Can I generate the segments.gen and segments_2 files without having to regenerate the _0.cfs file. Does these "segments" files contain any index specific data, which will thus force me to regnerate the entire index again. Or can I just generate the two "segments" file by copying these from another lucen index directory gnerated with the same lucene version.

  • Emulating hyperlink functionality in datawindow text fields

    - by mortalitysequence
    The idea is rather simple. Some datawindow (not web datawindow) varchar fields contain detailed descriptions. I was wondering if it is possible to provide the following (wikipedia-like) functionality to users: The ability to click (or dbl-click or whatever) on specific words of the text, while reading (which somehow should be indicated as clickable - it would be perfect if they could be colored blue but I don't think this is possible) and open a relevant window (or response). Do you think something like this could be implemented?
