    - by Hamza Yerlikaya
    I am looking for behavior tree implementations in any language, I would like to learn more about how they are implemented and used so can roll my own but I could only find one Owyl, unfortunately, it does not contain examples of how it is used. Any one know any other open source ones that I can browse through the code see some examples of how they are used etc? EDIT: Behavior tree is the name of the data structure.

  • Android: how to share code between projects signed with the same certificate

    - by tomash
    In Android documentation concerning code signing we can read: "By signing multiple applications with the same certificate and using signature-based permissions checks, your applications can share code and data in a secure manner." How exactly such code sharing can be done? Is it possible to release main application and multiple exchangeable plugins then discover them at runtime? What does source code looks like and what are advantages over "standard" intents calls from/to different APK packages?

  • What bugs apply to the different FindBugs reportLevels?

    - by Daniel H
    According to the Ant task, the report level is a low/medium/high setting that would look for bugs of different criticallity levels. However, there isn't anything I could find that explains which of the bugs apply to these different reporting levels. Is there somewhere that provides this, even if it is something I need to look at within the source?

  • Should I put my flex project within my rails project?

    - by ChrisInCambo
    I have a project with a RESTful Rails back-end and a Flex front-end, first time for me with this combo and I debating whether to put the flex source somewhere inside the Rails folder hierarchy or making it a separate project. If I do so which folder would be most suitable /lib? Also be doing one click deployment with Vlad which can also compile the flex app and dump it in the public folder. Or does anyone have any good reasons why the flex project shouldn't reside within the Rails folder hierarchy? Cheers

  • WPF Binding with RelativeSource of Window Requires "DataContext" in Path?

    - by Phil Sandler
    The following code works, but I'm curious as to why I need the Path to be prefixed with "DataContext"? In most other cases, the path used is relative to DataContext. Is it because I am using a RelativeSource? Because the source is at the root level (Window)? <Style TargetType="TextBox"> <Setter Property="IsReadOnly" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=DataContext.IsReadOnly}"/> </Style>

  • drawing hierarchical tree with orthogonal lines

    - by user267530
    Hi I need to work on drawing a hierarchical tree structure with orthogonal lines(straight rectangular connecting lines) between root and children ( like the following: http://lab.kapit.fr/display/visualizationlayouts/Hierarchical+Tree+layout ). I want to know if there are any open source examples of the algorithm of drawing trees like that so that I can implement the same algorithm in actionscript. Thanks Palash

  • WTF is wtf? (in WebKit code base)

    - by Motti
    I downloaded Chromium's code base and ran across the WTF namespace. namespace WTF { /* * C++'s idea of a reinterpret_cast lacks sufficient cojones. */ template<typename TO, typename FROM> TO bitwise_cast(FROM in) { COMPILE_ASSERT(sizeof(TO) == sizeof(FROM), WTF_wtf_reinterpret_cast_sizeof_types_is_equal); union { FROM from; TO to; } u; u.from = in; return u.to; } } // namespace WTF Does this mean what I think it means? Could be so, the bitwise_cast implementation specified here will not compile if either TO or FROM is not a POD and is not (AFAIK) more powerful than C++ built in reinterpret_cast. The only point of light I see here is the nobody seems to be using bitwise_cast in the Chromium project. I see there's some legalese so I'll put in the little letters to keep out of trouble. /* * Copyright (C) 2008 Apple Inc.

How do you do such thing?

  • Storage of events in Calendar application in Android 2.1

    - by Navin
    Does the calendar application in Android maintain a cache of its database? Whenever I edit and mark some events via the calendar app, it is stored in the database but if I edit the calendar.db from some outside source the changes made are not reflected in the calendar app. So my question is: Does the calendar app maintain a cache or some other form of database? If yes then where and how?

  • Using Google Common Collection in GWT

    - by Jeeyoung Kim
    This is a simple problem, but I'm having problems with it... I'm trying to use Google common collection's Objects.equal() method in a GWT client code, but I'm keep getting the error "20:12:10.001 [ERROR] [gwt_regex] Line 39: No source code is available for type com.google.common.base.Objects; did you forget to inherit a required module?" Tried to Google for the answer, but couldn't find any answer regarding this - everyone just said "Google collection should work off the box with GWT".

  • How much information does pdb files contain? (C# / .NET)

    - by Silver Dragon
    Is is wise to redistribute the pdb files along with a commercial application? Occasionally, I'm using the stack trace to get a more detailed error reporting logs from the deployed applications; can this functionality be achieved without relying to those files? Also, how much hints of the original source code does these files contain? Would it be easier to reverse-engineer my application using it?

  • How to get absolute paths after vpath matching in make?

    - by Honza
    I have a makefile that depending on some properties sets vpath and generates a list of source files into one variable. I need to run the makefile without compiling anything (the compilation is actually handled by a different makefile) and just see to which real files the filenames get matched depending on the vpath settings.

  • Explain why MickroC pic18f4550 HID example works

    - by Dr Deo
    MickroC compiler has a library for HID(Human Interface Device) usb communication. In the supplied samples, they specify that the buffers below should be in USB ram and use a pic18f4550. unsigned char readbuff[64] absolute 0x500; // Buffers should be in USB RAM, please consult datasheet unsigned char writebuff[64] absolute 0x540; But the pic18f4550 datasheet says USB ram ranges from 400h to 4FFh So why does their example work when their buffers appear not to be between 400h to 4FFh?

  • Backslash escaping in RegularExpressionValidator

    - by frogbot
    I need to ensure that the input value contains at least one dot, so i use the following: <asp:RegularExpressionValidator runat="server" ControlToValidate="MyInput" Text="*" ErrorMessage="must contain at least one dot" ValidationExpression="\.+" /> And that doesn't work. By inspecting the page source i can see that ASP.NET escapes the backslash character so in java-script it looks like "\\.+". Why does it do so and how do i prevent RegularExpressionValidator from escaping it?
