  • What data structures and algorithms are applied within data warehouse cubes?

    - by Jeff Meatball Yang
    I understand that cubes are optimized data structures for aggregating and "slicing" large amounts of data. I just don't know how they are implemented. I can imagine a lot of this technology is proprietary, but are there any resources that I could use to start implementing my own cube technology? Set theory and lots of math are probably involved (and welcome as suggestions!), but I'm primarily interested in implementations: the data structures and query algorithms. Thanks!

  • SVN syncing fails with ZendStudio

    - by rashcroft
    Hi. When I try to sync with my SVN (I'm using unfuddle) through ZendStudio I get the following error: Some of selected resources were not committed. svn: Commit failed (details follow): svn: MKACTIVITY request failed on '/svn/test1234_a/!svn/act/58ae0e6d-2301-0010-8300-cb465553b788' svn: MKACTIVITY of '/svn/test1234_a/!svn/act/58ae0e6d-2301-0010-8300-cb465553b788': 400 Bad Request (http://test1234.unfuddle.com) I think this is some type of proxy error, but how can I fix this (using ZendStudio). Thanks.

  • How can I bind a instance of a custom class to a WPF TreeListView without bugs?

    - by user327104
    First, from : http://blogs.msdn.com/atc_avalon_team/archive/2006/03/01/541206.aspx I get a nice TreeListView. I left the original classes (TreeListView, TreeListItemView, and LevelToIndentConverter) intact, the only code y have Added is on the XAML, here is it: <Style TargetType="{x:Type l:TreeListViewItem}"> .... </ControlTemplate.Triggers> <ControlTemplate.Resources> <HierarchicalDataTemplate DataType="{x:Type local:FileInfo}" ItemsSource="{Binding Childs}"> </HierarchicalDataTemplate> </ControlTemplate.Resources> </ControlTemplate> ... here is my custom class public class FileInfo { private List<FileInfo> childs; public FileInfo() { childs = new List<FileInfo>(); } public bool IsExpanded { get; set; } public bool IsSelected { get; set; } public List<FileInfo> Childs { get { return childs; } set { } } public string FileName { get; set; } public string Size { get; set; } } And before I use my custom class I remove all the items inside the treeListView1: <l:TreeListView> <l:TreeListView.Columns> <GridViewColumn Header="Name" CellTemplate="{StaticResource CellTemplate_Name}" /> <GridViewColumn Header="IsAbstract" DisplayMemberBinding="{Binding IsAbstract}" Width="60" /> <GridViewColumn Header="Namespace" DisplayMemberBinding="{Binding Namespace}" /> </l:TreeListView.Columns> </l:TreeListView> So finaly I add this code to bind a Instance of my class to the TreeListView: private void Window_Loaded(object sender,RoutedEventArgs e) { FileInfo root = new FileInfo() { FileName = "mis hojos", Size="asdf" }; root.Childs.Add(new FileInfo(){FileName="sub", Size="123456" }); treeListView1.Items.Add(root); root.Childs[0].Childs.Add(new FileInfo() { FileName = "asdf" }); root.Childs[0].IsExpanded = true; } So the bug is that the button to expand the elementes dont appear and when a node is expanded by doble click the child nodes dont look like child nodes. Please F1 F1 F1 F1 F1 F1 F1 F1.

  • eclipse 3.5 filter .git folder

    - by jpfuentes2
    I'm using eclipse 3.5.2 and cannot seem to use "filter resources" to filter out .git folders in any of my projects for any of my perspectives: javascript, ruby, and php. I've tried adding the filter to plugin.xml as suggested on this blog but it is for eclipse 3.4 and doesn't seem to work. Any suggestions?

  • Java Security Manager for JRuby

    - by nijikunai
    I'm allowing user supplied ruby code to run in server(java scripting), and since jruby doesn't support safe-levels as in ruby I'm thinking about using java's security manager. Is this a good decision? Has anyone else implemented this? Are there any good articles/books/resources that introduce me to security manager?

  • Check if NSURL is Local File

    - by golfromeo
    This is a pretty simple question- how can I check if a NSURL is linking to a local file? I know, RTFM, but I checked the documentation and I don't seem to see any methods related to this. The only methods I did find were -isFileReferenceURL and -isFileURL, but I think these only check if the URL directly links to a file. note: I'm making an iPhone app, so by "local file" I mean a .html file stored in the project's resources. Thanks for any help in advance.

  • Literature and Tutorials for Writing a Ray Tracer

    - by grrussel
    I am interested in finding recommendations on books on writing a raytracer, simple and clear implementations of ray tracing that can be seen on the web, and online resources on introductory raytracing. Ideally, the approach would be incremental and tutorial in style, and explain both the programming techniques and underyling mathematics, starting from the basics.

  • What is Object Decomposition?

    - by Mustafa
    Hi everyone, I was trying to understand what object decomposition means and read a lot of stuff on internet but every resource talks in terms of lots of keywords that i couldn't understand. So these resources expect you to know a few terms. I need something that lists the basics of decomposition from scratch. Is it anything more than breaking the design into objects? If no, any description will be appreciated. Thanks in advance

  • Can I send a ctrl-C (SIGINT) to an application on Windows?

    - by Matthew Murdoch
    I have (in the past) written cross-platform (Windows/Unix) applications which, when started from the command line, handled a user-typed Ctrl-C combination in the same way (i.e. to terminate the application cleanly). Is it possible on Windows to send a Ctrl-C/SIGINT/equivalent to a process from another (unrelated) process to request that it terminate cleanly (giving it an opportunity to tidy up resources etc.)?

Please Help.

  • Open source ASP.net webforms examples

    - by Yaaqov
    I learning ASP.net, and am looking to create a rather straightforward WebForms ASP.net application, but I have very limited examples to work with. Is there a site that has a lot of ASP.net WebForms projects that are downloadable? Books seem to focus on narrow aspects of using Webforms, like session control, or using master pages, but I'm looking for examples of how a whole app comes together. Or, better yet, is there someone willing to help a new developer out one-on-one by sharing a project or two of his? I'd appreciate any help. Thanks.

  • About Network Address Translation (NAT)?

    - by Rudi
    Just curious about a particular scenario of NAT. Let's suppose we have 4 computers sharing a global IP address under the NAT. I understand that the NAT box keeps an internal record to know which computer to forward requests to. But let's say on computer #2 I'm trying to download a file. And let's say on computer #1, #3, and #4, I'm just browsing the web normally. When the browser initiates a TCP connection to get that file, how does it know which computer to give it to? I mean like, each of the four computers is using port 80 to browse the web right? How does the NAT's record distinguish which "port 80" belongs to which computer?

  • How to determine if code is running in Foundation or GUI?

    - by Mitch Cohen
    I'm writing a Mac app with two targets - a regular Cocoa GUI and a Foundation command-line tool. They do very similar things other than the GUI, so I'm sharing most of the code between the two. I'd like to do a few things slightly differently depending on which target is running. I can think of many ways to do this (#define something in the pch, check for existence of GUI definitions...). I'm curious if there's a standard or recommended way to do this. Thanks!

  • What is your favourite Windbg tip/trick?

    - by user15071
    I have come to realize that Windbg is a very powerful debugger for the Windows platform & I learn something new about it once in a while. Can fellow Windbg users share some of their mad skills? ps: I am not looking for a nifty command, those can be found in the documentation. How about sharing tips on doing something that one couldn't otherwise imagine could be done with windbg? e.g. Some way to generate statistics about memory allocations when a process is run under windbg.

  • Learning the Introspection API (used by FxCop)

    - by Anand Patel
    Microsoft's FxCop tool uses the introspection API. This introspection API could be used to develop new code analysis tools. But the introspection api is not documented well. Additionally, I was not able to figure out any blogs which explains this API in breadth and depth of it. The knowledge gained by understanding the API can also be used for writing custom FxCop rules. Does anybody knows about any blog or resources which explains the same?

  • Learning MVVM for WPF

    - by Mohit Deshpande
    I am now very comfortable with WPF, but I read some articles about MVP and MVVM that find the default project solution ineffective. Then I realized how ineffective it was and how the MVVM pattern is much better. So I want to really learn this pattern. Can I be directed to some resources like maybe a tutorial or a video or something?
