    - by norm
    Anybody know if it is possible that when making a tar + gzip through 'tar c ...' command if the relative paths will be ignored upon expanding. e.g. tar cvf test.tgz foo ../../files/bar and then expanding the test.tgz with: tar xvf test.tgz gives a dir containing: foo files/bar i want the dir to contain the files foo bar is this possible?

  • Clone submodule into directory

    - by andypaxo
    I'm having an issue with creating a submodule in my project. If I create the submodule directly in the repository root, everything works fine. If the submodule is any deeper, the repository does not get cloned. For example, this works as expected: git submodule add git://someproject.com/.git someproject However, when I run the following command, the project is added to .gitmodules and an empty repository is created, but no code is pulled down (even after a git submodule update --init). The command does not produce any output. git submodule add git://someproject.com/.git lib/someproject

  • How should I structure my turn based engine to allow flexibility for players/AI and observation?

    - by Reefpirate
    I've just started making a Turn Based Strategy engine in GameMaker's GML language... And I was cruising along nicely until it came time to handle the turn cycle, and determining who is controlling what player, and also how to handle the camera and what is displayed on screen. Here's an outline of the main switch happening in my main game loop at the moment: switch (GameState) { case BEGIN_TURN: // Start of turn operations/routines break; case MID_TURN: switch (PControlledBy[Turn]) { case HUMAN: switch (MidTurnState) { case MT_SELECT: // No units selected, 'idle' UI state break; case MT_MOVE: // Unit selected and attempting to move break; case MT_ATTACK: break; } break; case COMPUTER: // AI ROUTINES GO HERE break; case OBSERVER: // OBSERVER ROUTINES GO HERE break; } break; case END_TURN: // End of turn routines/operations, and move Turn to next player break; } Now, I can see a couple of problems with this set-up already... But I don't have any idea how to go about making it 'right'. Turn is a global variable that stores which player's turn it is, and the BEGIN_TURN and END_TURN states make perfect sense to me... But the MID_TURN state is baffling me because of the things I want to happen here: If there are players controlled by humans, I want the AI to do it's thing on its turn here, but I want to be able to have the camera follow the AI as it makes moves in the human player's vision. If there are no human controlled player's, I'd like to be able to watch two or more AI's battle it out on the map with god-like 'observer' vision. So basically I'm wondering if there are any resources for how to structure a Turn Based Strategy engine? I've found lots of writing about pathfinding and AI, and those are all great... But when it comes to handling the turn structure and the game states I am having trouble finding any resources at all. How should the states be divided to allow flexibility between the players and the controllers (HUMAN, COMPUTER, OBSERVER)? Also, maybe if I'm on the right track I just need some reassurance before I lay down another few hundred lines of code...

  • Can't get directory listing on my Apache to work.

    - by joon
    Hi, I'm having trouble enabling the directory listing on apache. I did it a few weeks ago but had to reinstall cause my Wubi ran out of space, and now I can't get it to work and it's driving me crazy. I have a folder /home/joon/Dropbox/Projects/apache, which I want to set as the root for my apache. Here's the first lines of the 'default' file in the sites-available folder: <VirtualHost *:8888> ServerAdmin webmaster@localhost DocumentRoot /home/joon/Dropbox/Projects/apache <Directory /home/joon/Dropbox/Projects/apache> Options +Indexes FollowSymLinks AllowOverride None The rest is unchanged. Ports.conf is set to Listen 8888. I thought the +Indexes should do it, but I must have overlooked something. I get a 403, forbidden. "You don't have permission to access / on this server." If I input the url of an image, http://127.0.0.1:8888/joon/bin/1chart.png, it displays, but no directory listing. Please help.

  • Looking for a smart sync tool that exactly copies the structure of the source to that of the destination

    - by ????????
    I am a Windows 7 user and looking for a sync tool that exactly copies the structure of the source to that of the destination. The scenario is as follows: I have a laptop in which I save my daily projects. I always bring this laptop wherever I go to work, either at my school or at my house. At school I have a room in which I put an external hard drive to backup my laptop data. Upon arriving at school I always sync the external data with my laptop. Before leaving the school, I also do the synchronization if I make some modification in my laptop data. I do the same thing when I arrive and leave my house. Every month I reformat my laptop because of some trial softwares. I am using SyncToy 2.1 to sync the external drives with my laptop. The problem is as follows. Before formatting my laptop, I sync all external drives with my laptop. For example, My laptop structure: c:\data\file1.ext c:\data\folder1\file2.ext Both external drive structure: d:\data\file1.ext d:\data\folder1\file2.ext After reformatting my laptop, I move the file1.ext to folder1. So my laptop structure becomes, c:\data\folder1\file1.ext c:\data\folder1\file2.ext If I sync external drives with my laptop, I get d:\data\file1.ext d:\data\folder1\file1.ext d:\data\folder1\file2.ext I want the tool also remove d:\data\file1.ext. How to do this?

  • Why the current working directory changes when use the Open file dialog in XP?

    - by RRUZ
    I have found an strange behavior when use the open file dialog in c#. If use this code in Windows XP the current working directory changes to the path of the selected file, however if you run this code in windows 7 the current working directory does not change. private void button1_Click(object sender, EventArgs e) { MessageBox.Show(string.Format("Current Directory {0}",Directory.GetCurrentDirectory()), "My Application",MessageBoxButtons.OK, MessageBoxIcon.Asterisk); DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog and get result. if (result == DialogResult.OK) { } MessageBox.Show(string.Format("Current Directory {0}", Directory.GetCurrentDirectory()), "My Application", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); } Anybody know the reason for this behavior? Why the current directoiry changes in XP and not in windows 7?

  • Netlogo behaviorspace, How to export each experiment's plot in a separate directory with a unique name? (Answer is by using pathdir extension)

    - by Marzy
    I have a save-plots function which I call it in my final command of behavior space to export selected plots, I could create unique names for plots so they don't replace each other, for example my output file name for one of the plots is like this: DeathRates, PS true, HCHA false 100,true.csv Let FileNameDeathRates ( word "D: /Results/" "DeathRates, " "PS "PS? ", HCHA " HCHA? MPS "," CV? ".csv" ) So far is good, but I want is to have a directory with name of the experiment and export all plots of that experiment in that directory for example: Let DirName( word "D:/Results/" "PS "PS? ", HCHA " HCHA? MPS "," CV? ) Netlogo already exports plots with proper name and I just want the directory name to be different , and of course prior to the experiment the directory does not exist so the directory should be created first , I could not find a command to create a directory in netlogo without pathdir extension. Any idea on how can I do this? Thanks in advance ;)

  • Where's My Windows Azure Subscriptions

    - by Shaun
    Originally posted on: http://geekswithblogs.net/shaunxu/archive/2013/11/03/wheres-my-windows-azure-subscriptions.aspxYesterday when I opened Windows Azure manage portal I found some resources were missed. I checked the website for those missed cloud service and they are still live. Then I checked my billing history but didn't found any problem. When I back to the portal I found that all of those resource are under my MSDN subscription. So I remembered that if this is related with the recently Windows Azure platform update.   This feature named "Enterprise Management", which provides the ability to manage your organization in a directory which is hosted entirely in the cloud, or alternatively kept in sync with an on-premises Windows Server Active Directory solution. By default, all existing windows azure account would have a default Windows Azure Active Directory (a.k.a. WAAD) associated. In the address bar I can find the default login WAAD of my account, which is "microsoft.onmicrosoft.com". To change the WAAD we can click "subscriptions" on top of the manage portal, select the active directory from the list of "filter by directory" and select the subscription we want to see, then press "apply". As you can see, the subscription under my MSDN was located in a WAAD named "beijingtelecom.onmicrosoft.com". This is because when Microsoft applied this feature, they will check if you have an existing WAAD in your subscription. If not, it will create a new one, otherwise it will use your WAAD and move your subscription into this directory. Since I created a WAAD for test several months ago, this subscription was moved to this directory.   To change the subscription's directory is simple. First we need to create a new WAAD with the name we preferred. As below I created a new directory named "shaunxu". Then select "settings" from the left navigation bar, select the subscription we wanted to change and click "edit directory". You don't have the permission to edit/change directory unless your Microsoft Account is the service administrator of this subscription. Then in the popup window, select the WAAD you want to change and press "next". All done. You need to log off and log in the portal then your subscription will be in the directory you wanted. And after these steps I can view my resources in this subscription.   Summary In this post I described how to change subscriptions into a new directory. With this new feature we can manage our Windows Azure subscription more flexible. But there are something we need keep in mind. 1. Only the service administrator could be able to move subscription. 2. Currently there's no way for us to see our Windows Azure services in more than one directory at the same time. Like me, I can see my services under "shaunxu.onmicrosoft.com" and I must change the filter directory from the "subscriptions" menu to see other services under "microsoft.onmicrosoft.com". 3. Currently we cannot delete an existing WAAD.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind. Copyright © Shaun Ziyan Xu.

  • How should I plan the inheritance structure for my game?

    - by Eric Thoma
    I am trying to write a platform shooter in C++ with a really good class structure for robustness. The game itself is secondary; it is the learning process of writing it that is primary. I am implementing an inheritance tree for all of the objects in my game, but I find myself unsure on some decisions. One specific issue that it bugging me is this: I have an Actor that is simply defined as anything in the game world. Under Actor is Character. Both of these classes are abstract. Under Character is the Philosopher, who is the main character that the user commands. Also under Character is NPC, which uses an AI module with stock routines for friendly, enemy and (maybe) neutral alignments. So under NPC I want to have three subclasses: FriendlyNPC, EnemyNPC and NeutralNPC. These classes are not abstract, and will often be subclassed in order to make different types of NPC's, like Engineer, Scientist and the most evil Programmer. Still, if I want to implement a generic NPC named Kevin, it would nice to be able to put him in without making a new class for him. I could just instantiate a FriendlyNPC and pass some values for the AI machine and for the dialogue; that would be ideal. But what if Kevin is the one benevolent Programmer in the whole world? Now we must make a class for him (but what should it be called?). Now we have a character that should inherit from Programmer (as Kevin has all the same abilities but just uses the friendly AI functions) but also should inherit from FriendlyNPC. Programmer and FriendlyNPC branched away from each other on the inheritance tree, so inheriting from both of them would have conflicts, because some of the same functions have been implemented in different ways on the two of them. 1) Is there a better way to order these classes to avoid these conflicts? Having three subclasses; Friendly, Enemy and Neutral; from each type of NPC; Engineer, Scientist, and Programmer; would amount to a huge number of classes. I would share specific implementation details, but I am writing the game slowly, piece by piece, and so I haven't implemented past Character yet. 2) Is there a place where I can learn these programming paradigms? I am already trying to take advantage of some good design patterns, like MVC architecture and Mediator objects. The whole point of this project is to write something in good style. It is difficult to tell what should become a subclass and what should become a state (i.e. Friendly boolean v. Friendly class). Having many states slows down code with if statements and makes classes long and unwieldy. On the other hand, having a class for everything isn't practical. 3) Are there good rules of thumb or resources to learn more about this? 4) Finally, where does templating come in to this? How should I coordinate templates into my class structure? I have never actually taken advantage of templating honestly, but I hear that it increases modularity, which means good code.

  • Creating a file/folder structure and zipping it up?

    - by makeee
    I have a directory of image files and I need a php script or shell script that will rename them, create a structure of nested directories, and then insert each image into a specified place in the directory hierarchy. Ideally I would just specify a parent directory for each file and a parent directory for each directory and it would build it. And then finally, I need the script to zip up the whole thing. There's probably not an existing php class that will do all this for me, but if anyone knows of a php class or other script available online that would handle a lot of this logic that would be great.

  • In PHP... best way to turn string representation of a folder structure into nested array

    - by Greg Frommer
    Hi everyone, I looked through the related questions for a similar question but I wasn't seeing quite what I need, pardon if this has already been answered already. In my database I have a list of records that I want represented to the user as files inside of a folder structure. So for each record I have a VARCHAR column called "FolderStructure" that I want to identify that records place in to the folder structure. The series of those flat FolderStructure string columns will create my tree structure with the folders being seperated by backslashes (naturally). I didn't want to add another table just to represent a folder structure... The 'file' name is stored in a separate column so that if the FolderStructure column is empty, the file is assumed to be at the root folder. What is the best way to turn a collection of these records into a series of HTML UL/LI tags... where each LI represents a file and each folder structure being an UL embedded inside it's parent?? So for example: file - folderStructure foo - bar - firstDir blue - firstDir/subdir would produce the following HTML: <ul> <li>foo</li> <ul> <li> bar </li> <ul> <li> blue </li> </ul> </ul> </ul> Thanks

  • Should I use structure from a core library graphic toolkit in my domain?

    - by Laurent Bourgault-Roy
    In java (and many other programming language), there are often structure to deal with graphic element : Colour, Shape, etc. Those are most often in a UI toolkit and thus have a relatively strong coupling with UI element. Now, in the domain of my application, we often deal with colour, shape, etc, to display statistic information on an element. Right now all we do with it is display/save those element with little or no behaviour. Would it make sense to avoid "reinventing the wheel" and directly use the structures in java.awt.* or should I make my own element and avoid a coupling to this toolkit? Its not like those element are going away anytime soon (they are part of the core java library after all), but at the same time it feel weird to import java.awt.* server side. I have no problem using java.util.List everywhere. Should I feel different about those class? What would be the "recommended" practice in that case?

  • Structure of a correctly implemented JTable with TableModel and Listeners?

    - by bamboocha
    I am pretty new to Java and its JTables and this is where I am struggling at the moment. I need to create a GUI which shows me results of a sql query like SELECT * FROM tblPeople WHERE name='Doe'. My idea was to create a a JFrame which displays a JTable with all found records. Besides this, I need to also implement some code to handle when a user is double clicking a record or selecting it by using his arrow keys (additional feature: pressing 12(e.g.) should select the 12th record). What is the best way to structure my program (what classes do I need and especially where do I store my logic)? I came up with structuring it the following way: Main.java ("view") SQLConnection.java PeopleTableModel.java (only stores and returns data given by the passed ResultSet, "model" inherits from DefaultTableModel) PeopleTable.java (stores basically all my logic including KeyListener and MouseListener, "controller", inherits from JTable) Are there better ways to achieve my goals? If so, what are they?
