  • Is there a RAD for Android ?

    - by mawg
    Anything to help design GUI like a paint program? (Delphi, VB, MSVC, QtBuilder, etc) And anything to help build packages, set permissions, etc? What is there out there to take the drudge work out of Android app creation and leave me free to concentrate on design and development?

  • Gomoku array-based AI-algorithm?

    - by Lasse V. Karlsen
    Way way back (think 20+ years) I encountered a Gomoku game source code in a magazine that I typed in for my computer and had a lot of fun with. The game was difficult to win against, but the core algorithm for the computer AI was really simply and didn't account for a lot of code. I wonder if anyone knows this algorithm and has some links to some source or theory about it. The things I remember was that it basically allocated an array that covered the entire board. Then, whenever I, or it, placed a piece, it would add a number of weights to all locations on the board that the piece would possibly impact. For instance (note that the weights are definitely wrong as I don't remember those): 1 1 1 2 2 2 3 3 3 444 1234X4321 3 3 3 2 2 2 1 1 1 Then it simply scanned the array for an open location with the lowest or highest value. Things I'm fuzzy on: Perhaps it had two arrays, one for me and one for itself and there was a min/max weighting? There might've been more to the algorithm, but at its core it was basically an array and weighted numbers Does this ring a bell with anyone at all? Anyone got anything that would help?

  • Can't step into stored procedure on remote SQL Server 2008

    - by abatishchev
    I have a domain installed on virtual Windows Server 2008 x64. SQL Server 2008 Express x64 is running in Windows Server 2008 x64 and client on Windows 7 RTM x86. Both are into the domain.

  • Git subtree not properly using .gitignore when doing a partial clone

    - by D W
    I am a graduate student with many scripts, bibliography data in bibtex, thesis draft in latex, presentations in open office, posters in scribus, and figures and result data. I would like to put everything in one project under version control. Then when I need to work on a portion such as the bibliography data, I would like to check that subdirectory out, modify it as necessary and merge it back.I would like the ability to check out one version to my home computer, and a different one to my work computer and make changes to each independently and eventually merge them back. I would also like to be able to check out a piece of code from this big project and import it with versioning into a separate project. If I may changes I'd like to be able to merge them back to the original project. Based on my understanding git subtree can do this. http://github.com/apenwarr/git-subtree There is an example that is along the lines of what I'm trying to do at: http://psionides.jogger.pl/2010/02/04/sharing-code-between-projects-with-git-subtree/ Say the trunk of my project contained the directories: (bib bin cfg data fig src todo). When I use git subtree split -P bib -b export git checkout export I get a the bib directory, plus all files that should have been ignored or considered binary based on .gitignore such as the src directory and everything in it that ends in a tilde or the ./data directory. dwickrama@DWwork:~/research/trunk$ ls * -r biblography.bib JabRef src: script1.sh~ README~ script2.sh~ script3.sh~ script4.R~ script5.awk~ script5.py~ cfg: cfgFile1.ini~ cfgFile2.ini~ cfgFile3.ini~ bin: bigBinaryPackage1 bigBinaryPackage2 dwickrama@DWwork:~/research/trunk$ My .gitignore file is as follows: *.doc diff=word *.tex diff=tex *.bib diff=bibtex *.py diff=python *.eps binary *.jpg binary *.png binary ./bin/* binary *~ How do I prevent this?

  • C# web cam WM_CAP_CONNECT: Want to force a capture source when multiple capture sources present.

    - by Codejoy
    I am using WebCam_Capture code I found online to access through C# a web cam. On a computer with one video source it works like a charm! (Program starts up at start up, finds the webcam and it works). Though on a computer with many video sources (Say a web cam and then manycam running on top of that), the program starts and queries the user which source to use. I would love my program to start up autonomously at the restart of a machine so this waiting for user input throws a wrench in that, anyway I can force it to just select say the first found source and go with that? So i have some webcam code I yes indeed found online here: http://channel9.msdn.com/forums/TechOff/93476-Programatically-Using-A-Webcam-In-C/?CommentID=94149 and now in preparing this post I did do more research and found out that my issue lies in this line from the above code: SendMessage(mCapHwnd, WM_CAP_CONNECT, 0, 0); That is what connects the webcam up, the only issue is that the above brings up this annoying video source dialog if I have more than one source. I want it to just use the first source so that dialog doesn't come up. I tried passing in different values where the 0's are, sure enough the dialog doesn't come up but it doesn't work either. Anyone know if there is a value I can pass to the SendMessage to suspend the dialog and yet have it select the first video source it finds?

  • How often are design patterns used in the workplace using PHP

    - by Metropolis
    Hey everyone, I read a book awhile back called PHP Design Patterns and Practice, and ever since then I have been using design patterns whenever I think they are needed. However it just occurred to me that maybe most companies do not use design patterns very often for PHP, or at all. What I was wondering is, do most companies use design patterns to help improve code flexibility? And if so, what are the best design patterns to learn for PHP? Thanks for any help on this, Metropolis

  • Using the Rijndael Object in VB.NET

    - by broke
    I'm trying out the Rijndael to generate an encrypted license string to use for our new software, so we know that our customers are using the same amount of apps that they paid for. I'm doing two things: Getting the users computer name. Adding a random number between 100 and 1000000000 I then combine the two, and use that as the license number(This probably will change in the final version, but I'm just doing something simple for demonstration purposes). Here is some sample codez: Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim generator As New Random Dim randomValue As Integer randomValue = generator.Next(100, 1000000000) ' Create a new Rijndael object to generate a key ' and initialization vector (IV). Dim RijndaelAlg As Rijndael = Rijndael.Create ' Create a string to encrypt. Dim sData As String = My.Computer.Name.ToString + randomValue.ToString Dim FileName As String = "C:\key.txt" ' Encrypt text to a file using the file name, key, and IV. EncryptTextToFile(sData, FileName, RijndaelAlg.Key, RijndaelAlg.IV) ' Decrypt the text from a file using the file name, key, and IV. Dim Final As String = DecryptTextFromFile(FileName, RijndaelAlg.Key, RijndaelAlg.IV) txtDecrypted.Text = Final End Sub That's my load event, but here is where the magic happens: Sub EncryptTextToFile(ByVal Data As String, ByVal FileName As String, ByVal Key() As Byte, ByVal IV() As Byte) Dim fStream As FileStream = File.Open(FileName, FileMode.OpenOrCreate) Dim RijndaelAlg As Rijndael = Rijndael.Create Dim cStream As New CryptoStream(fStream, _ RijndaelAlg.CreateEncryptor(Key, IV), _ CryptoStreamMode.Write) Dim sWriter As New StreamWriter(cStream) sWriter.WriteLine(Data) sWriter.Close() cStream.Close() fStream.Close() End Sub There is a couple things I don't understand. What if someone reads the text file and recognizes that it is Rijndael, and writes a VB or C# app that decrypts it? I don't really understand all of this code, so if you guys can help me out I will love you all forever. Thanks in advance

  • Looking for more details about "Group varint encoding/decoding" presented in Jeff's slides

    - by Mickey Shine
    I noticed that in Jeff's slides "Challenges in Building Large-Scale Information Retrieval Systems", which can also be downloaded here: http://research.google.com/people/jeff/WSDM09-keynote.pdf, a method of integers compression called "group varint encoding" was mentioned. It was said much faster than 7 bits per byte integer encoding (2X more). I am very interested in this and looking for an implementation of this, or any more details that could help me implement this by myself. I am not a pro and new to this, and any help is welcome!

  • Drupal: Exposing a module's data to Views2 using its API

    - by Sepehr Lajevardi
    I'm forking the filefield_stats module to provide it with the ability of exposing data into the Views module via the API. The filefield_stats module db table schema is as follow: <?php function filefield_stats_schema() { $schema['filefield_stats'] = array( 'fields' => array( 'fid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {files}.fid'), 'vid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {node}.vid'), 'uid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The {users}.uid of the downloader'), 'timestamp' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The timestamp of the download'), 'hostname' => array('type' => 'varchar', 'length' => 128, 'not null' => TRUE, 'default' => '', 'description' => 'The hostname downloading the file (usually IP)'), 'referer' => array('type' => 'text', 'not null' => FALSE, 'description' => 'Referer for the download'), ), 'indexes' => array('fid_vid' => array('fid', 'vid')), ); return $schema; } ?> Well, so I implemented the hook_views_api() in filefield_stats.module & added a filefield_stats.views.inc file in the module's root directory, here it is: <?php // $Id$ /** * @file * Provide the ability of exposing data to Views2, for filefield_stats module. */ function filefield_stats_views_data() { $data = array(); $data['filefield_stats']['table']['group'] = t('FilefieldStats'); // Referencing the {node_revisions} table. $data['filefield_stats']['table']['join'] = array( 'node_revisions' => array( 'left_field' => 'vid', 'field' => 'vid', ), /*'files' => array( 'left_field' => 'fid', 'field' => 'fid', ), 'users' => array( 'left_field' => 'uid', 'field' => 'uid', ),*/ ); // Introducing filefield_stats table fields to Views2. // vid: The node's revision ID which wrapped the downloaded file $data['filefield_stats']['vid'] = array( 'title' => t('Node revision ID'), 'help' => t('The node\'s revision ID which wrapped the downloaded file'), 'relationship' => array( 'base' => 'node_revisions', 'field' => 'vid', 'handler' => 'views_handler_relationship', 'label' => t('Node Revision Reference.'), ), ); // uid: The ID of the user who downloaded the file. $data['filefield_stats']['uid'] = array( 'title' => t('User ID'), 'help' => t('The ID of the user who downloaded the file.'), 'relationship' => array( 'base' => 'users', 'field' => 'uid', 'handler' => 'views_handler_relationship', 'label' => t('User Reference.'), ), ); // fid: The ID of the downloaded file. $data['filefield_stats']['fid'] = array( 'title' => t('File ID'), 'help' => t('The ID of the downloaded file.'), 'relationship' => array( 'base' => 'files', 'field' => 'fid', 'handler' => 'views_handler_relationship', 'label' => t('File Reference.'), ), ); // hostname: The hostname which the file has been downloaded from. $data['filefield_stats']['hostname'] = array( 'title' => t('The Hostname'), 'help' => t('The hostname which the file has been downloaded from.'), 'field' => array( 'handler' => 'views_handler_field', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort', ), 'filter' => array( 'handler' => 'views_handler_filter_string', ), 'argument' => array( 'handler' => 'views_handler_argument_string', ), ); // referer: The referer address which the file download link has been triggered from. $data['filefield_stats']['referer'] = array( 'title' => t('The Referer'), 'help' => t('The referer which the file download link has been triggered from.'), 'field' => array( 'handler' => 'views_handler_field', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort', ), 'filter' => array( 'handler' => 'views_handler_filter_string', ), 'argument' => array( 'handler' => 'views_handler_argument_string', ), ); // timestamp: The time of the download. $data['filefield_stats']['timestamp'] = array( 'title' => t('Download Time'), 'help' => t('The time of the download.'), 'field' => array( 'handler' => 'views_handler_field_date', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort_date', ), 'filter' => array( 'handler' => 'views_handler_filter_date', ), ); return $data; } // filefield_stats_views_data() ?> According to the Views2 documentations this should work as a minimum, I think. But it doesn't! Also there is no error of any kind, when I come through the views UI, there's nothing about filefield_stats data. Any idea?

  • Is there a perfect algorithm for chess?

    - by Overflown
    Dear Stack Overflow community, I was recently in a discussion with a non-coder person on the possibilities of chess computers. I'm not well versed in theory, but think I know enough. I argued that there could not exist a deterministic Turing machine that always won or stalemated at chess. I think that, even if you search the entire space of all combinations of player1/2 moves, the single move that the computer decides upon at each step is based on a heuristic. Being based on a heuristic, it does not necessarily beat ALL of the moves that the opponent could do. My friend thought, to the contrary, that a computer would always win or tie if it never made a "mistake" move (however do you define that?). However, being a programmer who has taken CS, I know that even your good choices - given a wise opponent - can force you to make "mistake" moves in the end. Even if you know everything, your next move is greedy in matching a heuristic. Most chess computers try to match a possible end game to the game in progress, which is essentially a dynamic programming traceback. Again, the endgame in question is avoidable though. -- thanks, Allan Edit: Hmm... looks like I ruffled some feathers here. That's good. Thinking about it again, it seems like there is no theoretical problem with solving a finite game like chess. I would argue that chess is a bit more complicated than checkers in that a win is not necessarily by numerical exhaustion of pieces, but by a mate. My original assertion is probably wrong, but then again I think I've pointed out something that is not yet satisfactorily proven (formally). I guess my thought experiment was that whenever a branch in the tree is taken, then the algorithm (or memorized paths) must find a path to a mate (without getting mated) for any possible branch on the opponent moves. After the discussion, I will buy that given more memory than we can possibly dream of, all these paths could be found.

  • Citrix client slow to launch

    - by user706837
    Was wondering if anyone else experience Citrix client to launch very slowly. While I'm a Windows SA by trade, I consider myself Novice+ on Linux, but I doubt thats the problem. This is the simple scenario: 1. Login to Citrix server to work from home 2. Click on the published application; this typically starts the local Citrix client. 3. Citrix client should start and you're off. Problem is between #2 and #3 I click on the application and 8 out of 9 times there is a 60 second delay and then I get an SSL connection error. I suspect this error is misleading since the connection took too long to open. But I dont know how to prove it (or fix it). I'm able to successfully manually launch wfcmgr without errors; so this leads me to believe Citrix client is installed correctly. I even leave it running thinking this may help, but I don't see a difference with or without this running first. The only times I'm able to connect successfully is when the Citrix client starts up a few seconds after clicking on the application. I've searched online for articles that might help, but tried a number of fixes without much difference. Even tried "ln -sf /dev/urandom /dev/random" as suggested by this article, but no dice:http://forums.citrix.com/message.jspa?messageID=1381276 My System (specs that may be relevant) Sony VAIO Laptop VGN-NW270F Linux Mint 11.04 Problem using: FireFox and Chrome Any help would be appreciated. Just trying to either find an answer or guidance on how to determine why its taking so long to launch the Citrix Client. Thanks
