  • How should I create a mutable, varied jtree with arbitrary/generic category nodes?

    - by Pureferret
    Please note: I don't want coding help here, I'm on Programmers for a reason. I want to improve my program planning/writing skills not (just) my understanding of Java. I'm trying to figure out how to make a tree which has an arbitrary category system, based on the skills listed for this LARP game here. My previous attempt had a bool for whether a skill was also a category. Trying to code around that was messy. Drawing out my tree I noticed that only my 'leaves' were skills and I'd labeled the others as categories. Explanation of tree: The Tree is 'born' with a set of hard coded highest level categories (Weapons, Physical and Mental, Medical etc.). Fro mthis the user needs to be able to add a skill. Ultimately they want to add 'One-handed Sword Specialisation' for instance. To do so you'd ideally click 'add' with Weapons selected and then select One-handed from a combobox, then click add again and enter a name in a text field. Then click add again to add a 'level' or 'tier' first proficiency, then specialisation. Of course if you want to buy a different skill it's completely different, which is what I'm having trouble getting my head around let alone programming in. What is a good system for describing this sort of tree in code? All the other JTree examples I've seen have some predictable pattern, and I don't want to have to code this all in 'literals'. Should I be using abstract classes? Interfaces? How can I make this sort of cluster of objects extensible when I add in other skills not listed above that behave differently? If there is not a good system to use, if there a good process for working out how to do this sort of thing?

  • Remote file copy util (like rsync) but that will take account of data already copied (in this sessio

    - by Rory McCann
    Let's say I have a directory with 2 files, both are identical and quite large (e.g. 2GB ea.) I want to rsync that directory to a remote host. As I understand it (and I could be wrong), rsync calculates checksums of files. Surely if it sees 2 files with the same checksum it can just copy the first file, then do a local copy on the remote host for the 2nd file? That would make it faster, no? On a similar note, doesn't rsync hash all the remote files before copying? If it saw a different file with the same hash as a file that was to transfered, it could do a local copy on the remote host. Does rsync support this sort of thing? Is there some way to turn it on? Is there a tool similar to rsync that will do this sort of 'hash based' local copies?

  • Why does my VertexDeclaration apparently not contain Position0?

    - by Phil
    I'm trying to get my code from calling each individual draw call down to using at least a VertexBuffer, and preferably an indexBuffer, but now that I'm attempting to test my code, I'm getting the error: The current vertex declaration does not include all the elements required by the current vertex shader. Position0 is missing. Which makes absolutely no sense to me, as my VertexDeclaration is: public readonly static VertexDeclaration VertexDeclaration = new VertexDeclaration( new VertexElement(0, VertexElementFormat.Vector3, VertexElementUsage.Position, 0), new VertexElement(sizeof(float) * 3, VertexElementFormat.Color, VertexElementUsage.Color, 0), new VertexElement(sizeof(float) * 3 + 4, VertexElementFormat.Vector3, VertexElementUsage.Normal, 0) ); Which clearly contains the information. I am attempting to draw with the following lines: VertexBuffer vb = new VertexBuffer(GraphicsDevice, VertexPositionColorNormal.VertexDeclaration, c.VertexList.Count, BufferUsage.WriteOnly); IndexBuffer ib = new IndexBuffer(GraphicsDevice, typeof(int), c.IndexList.Count, BufferUsage.WriteOnly); vb.SetData<VertexPositionColorNormal>(c.VertexList.ToArray()); ib.SetData<int>(c.IndexList.ToArray()); GraphicsDevice.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, vb.VertexCount, 0, c.IndexList.Count/3); Where c is a Chunk class containing an 8x8x8 array of boxes. Full code is available at https://github.com/mrbaggins/Box/tree/ProperMeshing/box/box. Relevant locations are Chunk.cs (Contains the VertexDeclaration) and Game1.cs (Draw() is in Lines 230-250). Not much else of relevance to this problem anywhere else. Note that large commented sections are from old version of drawing.

  • Why does my fan run so hard on my Dell XPS 15z?

    - by Kilhoffer
    I recently bought a Dell XPS 15z. It came with Windows 7 Home Premium, but I really wanted to try out Ubuntu on it. I ran the Windows installer and was surprised how smooth the process was. Within 10 minutes, I had a dual boot setup with Ubuntu 11.10. It boots into Ubuntu just fine and everything seems to work. I've read a lot about problems with touchpad and wireless, but honestly, I've had none of those issues. The only thing that's really bothering me is the fan constantly runs fast. Under Windows, it rarely ever came on and when it did, it wasnt spinning that fast. What could be going on under Ubuntu that would cause this? I want to get that under control because I want to use Ubuntu as my primary OS and screw Windows. Any help would be much appreciated! Note: I've read that others have set acpi=false, but I have not made any changes to the default installation. Should I make that change?

  • Offset Forward vector of object based on Rotation

    - by Taylor
    I'm using the Bullet 3D physics engine in a iOS application running openGL ES 1.1 Currently I'm accepting info from the gyroscope to allow the user to "look around" a 3d world that follows a bouncing ball (note: it only takes in the yaw to look around 360 degrees). Im also accepting information from the accelerometer based on the tilt to push the ball. As of right now, to move forward, the user tilts the devise forward (using the accelerometer); to move to the right, the user tilts the devise to the right and so on. The forward vector is currently along it's local Z-axis. The problem is that I want to change the ball bounce based on where the user has changed the view. If I change the view, the ball bounces in the fixed direction. I want to change the forward facing direction so that when a user changes the view (say to the look at the right of the world, the user rotates the device), tilting the devise forward will result in a forward force in that direction. Basically, I want the forward vector to take the rotation into consideration. Sorry if I didn't explain the issue well enough, its kind of confusing to write down.

  • How do I remove my Windows 7 setup from a Windows/Ubuntu dual-boot?

    - by Tom
    Previously my OS was Window 7 and some day it began to show problems with booting and finally it didn't boot at all. I tried to repair it but it didn't get repaired. Then I installed Ubuntu 14.04 LTS alongside Windows and am impressed much by Ubuntu. So I want to remove all my Windows files. I searched Google to know how to do it and I found OS-Uninstaller. I have some doubts before proceeding with OS-Uninstaller - I need to keep my photos, songs, movies and personal files in my system even if Windows is removed. Normally Windows files are installed in the C Drive. My personal files are not in the C Drive. So will removing Windows files affect my personal files ? Did the OS-Uninstaller affect Ubuntu anyway ? Please note that I want to remove only the Windows installation files(the files added to my system by Windows during its installation). I don't want to change the NTFS partition to any other format since there is a probability that I will install newer version of Windows later.

  • T-SQL select where and group by date

    - by bconlon
    T-SQL has never been my favorite language, but I need to use it on a fairly regular basis and every time I seem to Google the same things. So if I add it here, it might help others with the same issues, but it will also save me time later as I will know where to look for the answers!! 1. How do I SELECT FROM WHERE to filter on a DateTime column? As it happens this is easy but I always forget. You just put the DATE value in single quotes and in standard format: SELECT StartDate FROM Customer WHERE StartDate >= '2011-01-01' ORDER BY StartDate 2. How do I then GROUP BY and get a count by StartDate? Bit trickier, but you can use the built in DATEADD and DATEDIFF to set the TIME part to midnight, allowing the GROUP BY to have a consistent value to work on: SELECT DATEADD (d, DATEDIFF(d, 0, StartDate),0) [Customer Creation Date], COUNT(*) [Number Of New Customers] FROM Customer WHERE StartDate >= '2011-01-01' GROUP BY DATEADD(d, DATEDIFF(d, 0, StartDate),0) ORDER BY [Customer Creation Date] Note: [Customer Creation Date] and [Number Of New Customers] column alias just provide more readable column headers. 3. Finally, how can you format the DATETIME to only show the DATE part (after all the TIME part is now always midnight)? The built in CONVERT function allows you to convert the DATETIME to a CHAR array using a specific format. The format is a bit arbitrary and needs looking up, but 101 is the U.S. standard mm/dd/yyyy, and 103 is the U.K. standard dd/mm/yyyy. SELECT CONVERT(CHAR(10), DATEADD(d, DATEDIFF(d, 0, StartDate),0), 103) [Customer Creation Date], COUNT(*) [Number Of New Customers] FROM Customer WHERE StartDate >= '2011-01-01' GROUP BY DATEADD(d, DATEDIFF(d, 0, StartDate),0) ORDER BY [Customer Creation Date]  #

  • Test-service on Internet for testing incoming INVITE

    - by leiflundgren
    I am trying to set up Asterisk at home. I think I'm having trouble configuring my firewall, so that inbound traffic is accepted, but I am not sure. I got the idea that, perhaps, there is a service out on the Internet, where I can, though a web-browser, initiate an incoming call, an INVITE. And then see the SIP-trace that the remote-part experience. Anyone know of such a service? Note. I have a SIP-PSTN provider so I can generate inbound calls. But I cannot see the SIP-logs from my provider...

  • MySQL wants a password but it's empty

    - by gAMBOOKa
    mysql -uroot ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) mysql -uroot -p Enter password: <-- leave blank, hit enter without entering anything mysql> <-- i am logged in NOTE: This is a new mysql instance installation So if the password is blank, why won't it log me in without a -p flag? For a little clarification. I am running into this issue when attempting to change the password using a script: We're using a bash script to do that. mysqladmin -u root password abc wouldn't work (access denied) mysqladmin -u root -p password abc cannot be used because it prompts for a password and we need to automate this. mysqladmin -u root -p'' password abc is not working either

  • A desktop Wiki editor/viewer: is there anything out there?

    - by MrBertie
    I'm a big user of wikis, mainly Dokuwiki, I really like the clarity and ease of use of simple text files. However all good wikis seem to require a web-server of some kind; has anyone come across a good desktop wiki editor/viewer that work with plain-text files, and allow me to work with wiki text files just like any other document file type (note: not a desktop wiki running inside a local webserver) Before you rush to suggest (I hope!) I have done months of research on this and have tried Wixi, Wikidpad, zulupad.... Any ideas anyone?

  • How can I improve the "smoothness" of a 2D side-scrolling iPhone game?

    - by MrDatabase
    I'm working on a relatively simple 2D side-scrolling iPhone game. The controls are tilt-based. I use OpenGL ES 1.1 for the graphics. The game state is updated at a rate of 30 Hz... And the drawing is updated at a rate of 30 fps (via NSTimer). The smoothness of the drawing is ok... But not quite as smooth as a game like iFighter. What can I do to improve the smoothness of the game? Here are the potential issues I've briefly considered: I'm varying the opacity of up to 15 "small" (20x20 pixels) textures at a time... Apparently varying the opacity in this manner can degrade drawing performance I'm rendering at only 30 fps (via NSTimer)... Perhaps 2D games like iFighter are rendered at a higher frame rate? Perhaps the game state could be updated at a faster rate? Note the acceleration vales are updated at 100 Hz... So I could potentially update part of the game state at 100 hz All of my textures are PNG24... Perhaps PNG8 would help (due to smaller size etc)

  • Install Base Transaction Error Troubleshooting

    - by LuciaC
    Oracle Installed Base is an item instance life cycle tracking application that facilitates enterprise-wide life cycle item management and tracking capability.In a typical process flow a sales order is created and shipped, this updates Inventory and creates a new item instance in Install Base (IB).  The Inventory update results in a record being placed in the SFM Event Queue.  If the record is successfully processed the IB tables are updated, if there is an error the record is placed in the csi_txn_errors table and the error needs to be resolved so that the IB instance can be created.It's extremely important to be proactive and monitor IB Transaction Errors regularly.  Errors cascade and can build up exponentially if not resolved. Due to this cascade effect, error records need to be considered as a whole and not individually; the root cause of any error needs to be resolved first and this may result in the subsequent errors resolving themselves. Install Base Transaction Error Diagnostic Program In the past the IBtxnerr.sql script was used to diagnose transaction errors, this is now replaced by an enhanced concurrent program version of the script. See the following note for details of how to download, install and run the concurrent program as well as details of how to interpret the results: Doc ID 1501025.1 - Install Base Transaction Error Diagnostic Program  The program provides comprehensive information about the errors found as well as links to known knowledge articles which can help to resolve the specific error. Troubleshooting Watch the replay of the 'EBS CRM: 11i and R12 Transaction Error Troubleshooting - an Overview' webcast or download the presentation PDF (go to Doc ID 1455786.1 and click on 'Archived 2011' tab).  The webcast and PDF include more information, including SQL statements that you can use to identify errors and their sources as well as recommended setup and troubleshooting tips.

  • Simple algorithm for a sudoku solver java

    - by user142050
    just a quick note first, I originally asked this question on stack overflow but was refered here instead. I've been stuck on this thing for a while, I just can't wrap my head around it. For a homework, I have to produce an algorithm for a sudoku solver that can check what number goes in a blank square in a row, in a column and in a block. It's a regular 9x9 sudoku and I'm assuming that the grid is already printed so I have to produce the part where it solves it. I've read a ton of stuff on the subject I just get stuck expressing it. I want the solver to do the following: If the value is smaller than 9, increase it by 1 If the value is 9, set it to zero and go back 1 If the value is invalid, increase by 1 I've already read about backtracking and such but I'm in the early stage of the class so I'd like to keep it as simple as possible. I'm more capable of writing in pseudo code but not so much with the algorithm itself and it's the algorithm that is needed for this exercise. Thanks in advance for your help guys.

  • How to receive mail in Qmail?

    - by Ivan
    I've a server that uses Qmail. It is installed by default and it is supposed to work. I've created a new domain and new user (vadddomain + vadduser) without problems, but when I send an email from Gmail to [email protected] (the address I've created) it desappears, it is. But if connect to SMTP server directly (telnet domain.com 25) and post an email it arrives to the user queue. What's happening?!? Note: If I try to access to my user through telnet domain.com 110 it seems my pwd is not correct and it's the same I used when created the user with vadduser

  • Reporting memory usage per process/program

    - by Nick Retallack
    How can I get the current memory usage (preferably in bytes so they can be added up accurately) for all running processes individually? Can I roll up the summaries for child processes into the process that spawned them? (e.g all apache threads together). Sometimes, my server runs out of memory and becomes unresponsive. I want to discover what is using up all the memory. Unfortunately, it's likely to not be a single process. Some programs spawn hundreds of processes, each using very little memory, but it adds up. On a side note, is it normal for apache to spawn 200+ processes?

  • Workstation 7 build 203739 - Capture Movie Mouse Pointer Not Visible

    - by BMIVM
    Hi, I have noticed that whenever I create a Capture Movie, the movie is fine but the mouse pointer is not visible at all. The clicks are on buttons file menus are executed but is hard for a viewer of the capturre movie session to follow the recording smoothly. This was not a problem in previous versions of WorkStation. Is this a bug or is there a setting I can set to see the mouse pointer? Note: VM Tools are installed, Host is Vista Ultimate Edtion SP1, x64 and the guest is a Win XP SP2. Thanks in advance for your help.

  • Password Self-serve Active Directory via LAMP environment

    - by keithosu
    I would like to be able to change active directory passwords via a Linux/Apache based webpage. This would be a self serve web page for the user. I have SSL-LDAP setup on the Active Directory to make this happen. Is there any project or code out there that will do this? I've looked at this phpadadmin and I cannot get it to work. I think this is for IIS/php/mySQL Another thing to note is I would like the user to authenticate to change their own password. The product/service should not need a privileged account to run. Thanks Keith

  • How do I purge or empty Windows Explorer's network username and sharename cache?

    - by Abel
    While troubleshooting a Samba vs Windows Network issue, I noticed that Windows' Explorer remembers login credentials of remote shares, even if you ask it not to. For instance, after accessing a share using \\servername\sharename plus entering username/password and then closing Windows Explorer, adding the same share as a network drive gives the following message, regardless whether the username is the same or not: The network folder specified is currently mapped using a different user name and password. To connect using a different user name and password, first disconnect any existing mappings to this network share. Using NET USE does not show the share. After restarting the computer, I have no problems accessing the share using different credentials. But restarting just for testing other credentials is annoying, esp. while troubleshooting. How can I purge this cache, using Windows Vista? Note: using nbtstat -R[R], ipconfig /renew, killing explorer.exe or disabling / re-enabling the network card didn't help.

  • Remote Desktop Software - TeamViewer comparison?

    - by Martin
    Preliminary Note: After reading what I wrote below, I would like to stress that this ain't a TeamViewer ad. It's just that all other tools that I checkked online seem to miss one feature or the other. :-) OK, so I'm currently trying to get a picture of available solutions for remote desktop software. I have found (through personal usage) that TeamViewer pretty much ticks all boxes that I personally would want from any remoting tool. (Specifically it's setup is amazingly trivial.) It supports a wide range of platforms and it's even free for private use, so I'm really quite OK with it. I would be interested if anyone knows of other tools that ticks as many boxes as TeamViewer seems to do.

  • Patenting a Web Application before launch?

    - by SoreThumb
    While discussing a website idea I had with friends and worked on it, they told me to be wary of theft regarding the website. Since the code I'd be working on would be mostly Javascript and HTML, the likelihood of theft is quite high. Furthermore, if I'm lucky, the idea I have would be a breakthrough when it comes to being useful. So, you can see the problem here-- I would be developing an application that's easily stolen, and unfortunately an application that companies larger than myself would want to provide. I'm also unsure if this idea has already been patented. I realize patent law is murky as in you can create a vague patent and still claim others are violating it. So, I'd like to search existing patents for one that may be relevant to my idea, and I'd like to patent it in the meantime. Does anyone have any experience regarding this? Should I invite a lawyer into the mix? As a note, I was going to add tags like, "Patents", but nobody has asked such a question yet and I just joined this StackOverflow...

  • What are the keyboard shortcuts to operate a Mac slider control

    - by doekman
    In the Safari RSS screen, there is a slider (or range) control to change an article's summary length. By pressing TAB a couple of times, it is possible to navigate to this control, without using the mouse. Is it also possible, to slide the slider with the keyboard? Thus sliding the knob to the right and left? The volume slider in iTunes can be operated by the arrow-keys, but in Safari's RSS window, these are used to scroll the text if there are any scrollbars... Note: in System Preferences, Keyboard (OS X 10.6), Keyboard Shortcuts, I have set Full Keyboard Access to All controls. Otherwise, the TAB key only navigates between text boxes and lists.

  • How do I create a rule in Outlook 2010 that moves emails without special headers to a folder?

    - by burnersk
    I like to create a rule in Outlook 2010 that moves emails not containing a special string within the email header field message-id to a folder. How to do that? Pattern: not contains "SPECIAL-STRING". Example E-Mail: ... Date: Fri, 1 Sep 2012 11:16:32 +0100 Message-ID: <bla.bla.bla@SPECIAL-NOT-STRING> MIME-Version: 1.0 ... Hi there :) Pattern matches because "SPECIAL-STRING" is not present (note there is a "NOT" between the words). Automatically moves those emails to folder INBOX/other-mails.

  • Very high memory usage, but not claimed by any process?

    - by SharkWipf
    While stress-testing LVM on one of our Debian servers, I came across this issue where memory would fill up a lot to the point where it would run the server out of memory, but no process would claim the memory. See http://i.imgur.com/cLn5ZHS.png, and see http://serverfault.com/a/449102/125894 for an explanation on the colors used in htop. Why is this happening? And is there any way to see what process is using the memory? Htop is configured not to hide any processes, so what is it that htop is missing? In this particular case, I can fairly certainly say that it is caused, directly or indirectly, by lvmcreate, lvmremove or dmsetup, as I was stress-testing that. Do note that this question is not about solving the LVM problem, but about why the memory isn't claimed by any process. Stopping all LVM commands does bring the memory back down to <600MB.
