  • Solving 2D Collision Detection Issues with Relative Velocities

    - by Jengerer
    Imagine you have a situation where two objects are moving parallel to one-another and are both within range to collide with a static wall, like this: A common method used in dynamic collision detection is to loop through all objects in arbitrary order, solve for pair-wise collision detection using relative velocities, and then move the object to the nearest collision, if any. However, in this case, if the red object is checked first against the blue one, it would see that the relative velocity to the blue object is -20 m/s (and would thereby not collide this time frame). Then it would see that the red object would collide with the static wall, and the solution would be: And the red object passes through the blue one. So it appears to be a matter of choosing the right order in which you check collisions; but how can you determine which order is correct? How can this passing through of objects be avoided? Is ignoring relative velocity and considering every object as static during pair-wise checks a better idea for this reason?

  • Can not print after upgrading from 12.x to 14.04

    - by user318889
    After upgrading from V12.04 to V14.04 I am not able to print. I am using an HP LaserJet 400 M451dn. The printer troubleshooter told me that there is no solution to the problem.

  • Xcode Video From UITableView [migrated]

    - by Luis Felipe Beltran
    I have created different UITableViews. Each of these are dynamic tables that contain NSarrays of words. Right now When a cell is tabbed it takes the user to another View (simple view controller) that has a label and a UIImageview that displays a picture. My problem is that I also want to show video. Some of these words need to show pictures, and others need to show video. I have shown video before but I have done it using a button. I need help! I would appreciate if you guys could help here. Again, Im trying to show a video from a UITableView after the user tabs a cell. (I have many videos not just one, so dynamically would be better if possible)

  • get length of data sent over network to TCPlistener/networkstream vb.net

    - by Jonathan.
    It seems the most obvious thing, but I just can't work out how to get the length of bytes sent over a network using a TCPClient and TCPListener? This is my code so far: 'Must listen on correct port- must be same as port client wants to connect on. Const portNumber As Integer = 9999 Dim tcpListener As New TcpListener(IPAddress.Parse("192.168.2.7"), portNumber) tcpListener.Start() Console.WriteLine("Waiting for connection...") 'Accept the pending client connection and return 'a TcpClient initialized for communication. Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() Console.WriteLine("Connection accepted.") ' Get the stream Dim networkStream As NetworkStream = tcpClient.GetStream() '' Read the stream into a byte array I need to get the length of the networkstream to set the size of the array of bytes I'm going to read the data into. But the networkStream.length is unsupported and does not work and throws an Notsupportedexception. The only other way I can think of is to send the size of the data before sending the data, but this seems the long way round.

  • MS-Access nested DIR - check if a file exists elsewhere whilst looping through a folder

    - by David Carle
    I have used the DIR() command in Microsoft Access 2003 to loop through the files in folder A. This works fine, but I need to check if each file also exists in another location (folder B), and only process the file if it doesn't exist in folder B. The problem is that checking for the file existing in folder B also uses the DIR() function and this then resets or confuses the original one, with the result that no further files are found in folder A. Is there a way to check if a file exists without using DIR? Or, is there a way to have a separate instance of DIR? I suppose I could build a list of the files in folder A into an array and then process the entries in the array, but this seems rather 'clunky' Any suggestions for a better solution? Thanks

  • How does a search functionality fit in DDD with CQRS?

    - by Songo
    In Vaughn Vernon's book Implementing domain driven design and the accompanying sample application I found that he implemented a CQRS approach to the iddd_collaboration bounded context. He presents the following classes in the application service layer: CalendarApplicationService.java CalendarEntryApplicationService.java CalendarEntryQueryService.java CalendarQueryService.java I'm interested to know if an application will have a search page that feature numerous drop downs and check boxes with a smart text box to match different search patterns; How will you structure all that search logic? In a command service or a query service? Taking a look at the CalendarQueryService.java I can see that it has 2 methods for a huge query, but no logic at all to mix and match any search filters for example. I've heard that the application layer shouldn't have any business logic, so where will I construct my dynamic query? or maybe just clutter everything in the Query service?

  • Keeping Entitlements in Check

    - by Naresh Persaud
    Thanks for going the webcast on keeping entitlements in check. As a follow up, I have attached the slides to the webcast. The webcast will be available on demand shortly via IOUG.   A few key takeaways: Application security means applying both preventive and detective controls. Audit and security groups need the combination of both access certification and runtime dynamic authorization. Today, security policy is largely fragmented and brittle to change. The result is audit exposure for highly regulated applications.  By addressing the entire value chain of application security with a comprehensive platform approach, organizations can reduce the risk and improve compliance.    Ioug webcast entitlements in check View more PowerPoint from OracleIDM

  • Sort and display directory list alphabetically using opendir() in php

    - by felixthehat
    Hi there, php noob here - I've cobbled together this script to display a list of images from a folder with opendir, but I can't work out how (or where) to sort the array alphabetically <?php // opens images folder if ($handle = opendir('Images')) { while (false !== ($file = readdir($handle))) { // strips files extensions $crap = array(".jpg", ".jpeg", ".JPG", ".JPEG", ".png", ".PNG", ".gif", ".GIF", ".bmp", ".BMP", "_", "-"); $newstring = str_replace($crap, " ", $file ); //asort($file, SORT_NUMERIC); - doesnt work :( // hides folders, writes out ul of images and thumbnails from two folders if ($file != "." && $file != ".." && $file != "index.php" && $file != "Thumbnails") { echo "<li><a href=\"Images/$file\" class=\"thickbox\" rel=\"gallery\" title=\"$newstring\"><img src=\"Images/Thumbnails/$file\" alt=\"$newstring\" width=\"300\" </a></li>\n";} } closedir($handle); } ?> Any advice or pointers would be much appreciated!

  • Does pdksh (public domain korn shell) support associative arrays?

    - by George Jempty
    I recently ran up against a wall doing some bash shell programming where an associative array would have solved my problems. I googled about features of the Korn shell and learned that it supports associative arrays, so I installed Cygwin's pdksh (public domain korn shell). However, when trying to create an associative array in the prescribed manner (typeset -A varName), I received the following errors, so I'm beginning to suspect pdksh does not support associative arrays. ./find_actions.ksh: line 2: typeset: -A: invalid option typeset: usage: typeset [-afFirtx] [-p] name[=value] ... Guess I'll be considering Perl instead, but I really wanted a good excuse to learn a dialect/language new to me

  • Google Analytics Funnel Step Regular Expression Not Working

    - by scoarescoare
    The first step in a funnel is going to have a dynamic ending fragment. Examples: http://mysite.com/invite/tickle-party http://mysite.com/invite/pajama-party http://mysite.com/invite/puppy-party To allow for such dynamism, I provided this url for step one: \invite(.*) My goals work but the funnel visualization report shows 0 for everything. I know this problem is due to the regex in the funnel step because I copied this entire goal except I replaced \invite(.*) with /invite/puppy-party When I hardcoded /invite/puppy-party the funnel worked as expected. Why is my funnel report not working with my original funnel step url parameter?

  • Understanding how texCUBE works and writing cubemaps properly into a cube rendertarget

    - by cubrman
    My goal is to create accurate reflections, sampled from a dynamic cubemap, for specific 3d objects (mostly lights) in XNA 4.0. To sample the cubemap I compute the 3d reflection vector in a classic way: half3 ReflectionVec = reflect(-directionToCamera, Normal.rgb); I then use the vector to get the actual reflected color: half3 ReflectionCol = texCUBElod(ReflectionSampler, float4(ReflectionVec, 0)); The cubemap I am sampling from is a RenderTarget with 6 flat faces. So my question is, given the 3d world position of an arbitrary 3d object, how can I make sure that I get accurate reflections of this object, when I re-render the cubemap. Should I build the ViewProjection matrix in a specific way? Or is there any other approach?

  • In OpenRasta is it possible to Pattern match multiple key/value pairs?

    - by Scott Littlewood
    Is it possible in OpenRasta to have a Uri pattern that allows for an array of values of the same key to be submitted and mapped to a handler method accepting an array of the query parameters. Example: Return all the contacts named Dave Smith from a collection. HTTP GET /contacts?filterBy=first&filterValue=Dave&filterBy=last&filterValue=Smith With a configuration of: What syntax would be best for the Uri string pattern matching? (Suggestions welcome) ResourceSpace.Has.ResourcesOfType<List<ContactResource>>() .AtUri("/contacts") .And.AtUri("/contacts?filterBy[]={filterBy}[]&filterValue[]={fv}[]") // Option 1 .And.AtUri("/contacts?filterBy={filterBy}[]&fv={fv}[]") // Option 2 Would map to a Handler method of: public object Get(params Filter[] filters) { /* create a Linq Expression based on the filters using dynamic linq query the repository using the Linq */ return Query.All<Contact>().Where(c => c.First == "Dave" && c.Last == "Smith").ToResource() } where Filter is defined by public class Filter { public string FilterBy { get; set; } public string FilterValue { get; set; } }

  • iPhone OS: KVO: Why is my Observer only getting notified at applicationDidfinishLaunching

    - by nickthedude
    I am basically trying to implement an achievement tracking setup in my app. I have a managedObjectModel class called StatTracker to keep track of all sorts of stats and I want my Achievement tracking class to be notified when those stats change so I can check them against a value and see if the user has earned an achievement. I've tried to impliment KVO and I think I'm pretty close to making it happen but the problem I'm running into is this: So in the appDelegate i have an Ivar for my Achievement tracker class, I attach it as an observer to a property value of my statTracker core data entity in the applicationDidFinishLaunching method. I know its making the connection because I've been able to trigger a UIAlert in my AchievementTracker instance, and I've put several log statements that should be triggered whenever the value on the StatTracker's property changes. the log statement appears only once at the application launch. I'm wondering if I'm missing something in the whole object lifecycle scheme of things, I just don't understand why the observer stops getting notified of changes after the applicationDidFinishLaunching method has run. Does it have something to do with the scope of the AchievementTracker reference or more likely the reference to my core data StatTracker is going away once that method finishes up. I guess I'm not sure the right place to place these if that is the case. Would love some help. Here is the code where I add the observer in my appDidFinishLaunching method: [[CoreDataSingleton sharedCoreDataSingleton] incrementStatTrackerStat:@"timesLaunched"]; achievementsObserver = [[AchievementTracker alloc] init]; StatTracker *object = nil; object = [[[CoreDataSingleton sharedCoreDataSingleton] getStatTracker] objectAtIndex:0]; NSLog(@"%@",[object description]); [[CoreDataSingleton sharedCoreDataSingleton] addObserver:achievementsObserver toStat:@"refreshCount"]; here is the code in my core data singleton: -(void) addObserver:(id)observer toStat:(NSString *) statToObserve { NSLog(@"observer added"); NSArray *array = [[NSArray alloc] init]; array = [self getStatTracker]; [[array objectAtIndex:0] addObserver:observer forKeyPath:statToObserve options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:NULL]; } and my AchievementTracker: - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"achievemnt hit"); //NSLog("%@", [change description]); if ([keyPath isEqual:@"refreshCount"] && ((NSInteger)[change valueForKey:@"NSKeyValueObservingOptionOld"] == 60) ) { NSLog(@"achievemnt hit inside"); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"title" message:@"achievement unlocked" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:nil]; [alert show]; } }

  • Implement functionality in PHP?

    - by Rachel
    How can we Implement Bisect Python functionality in PHP Implement function bisect_left($arr, $item); as a pure-PHP routine to do a binary-bisection search for the position at which to insert $item into $list, maintaining the sort order therein. Assumptions: Assume that $arr is already sorted by whatever comparisons would be yielded by the stock PHP < operator, and that it's indexed on ints. The function should return an int, representing the index within the array at which $item would be inserted to maintain the order of the array. The returned index should be below any elements in $arr equal to $item, i.e., the insertion index should be "to the left" of anything equal to $item. Search routine should not be linear! That is, it should honor the name, and should attempt to find it by iteratively bisecting the list and comparing only around the midpoint.

  • Resources on concepts/theory behind GUI development?

    - by ShrimpCrackers
    I was wondering if there were any resources that explain concepts/theory behind GUI development. I don't mean a resource that explains how to use a GUI library, but rather how to create your own widgets. For example a resource that explains different methods on how to implement scrollable listboxes. I ask because I have an idea for a game tool where I would like to create my own widgets and let users drag and drop them onto some kind of form. How do GUI libraries usually draw widgets? I'm not sure if reskinning widgets from a GUI library fits my needs, since widget behavior needs to be dynamic based on user interaction.

I am using puppet on each server, and in the past have used resolv.conf to point to my search to the puppetmaster. search puppetmaster.com nameserver 192.168.1.XXX When trying to use the file on 12.04 resolv.conf the file gets over written when rebooted. I cannot use a static IP for these, so using the /etc/network/interfaces to help me out is a nill point. # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.0.1 Is there a way to get resolvconf to handle this either in the head, tail or base. If there is, are there any examples I can use to tweak on my server. Any help is much appreciated.

  • Java "compare cannot be resolved to a type" error

    - by King Triumph
    I'm getting a strange error when attempting to use a comparator with a binary search on an array. The error states that "compareArtist cannot be resolved to a type" and is thrown by Eclipse on this code: Comparator<Song> compare = new Song.compareArtist(); I've done some searching and found references to a possible bug with Eclipse, although I have tried the code on a different computer and the error persists. I've also found similar issues regarding the capitalization of the compare method, in this case compareArtist. I've seen examples where the first word in the method name is capitalized, although it was my understanding that method names are traditionally started with a lower case letter. I have experimented with changing the capitalization but nothing has changed. I have also found references to this error if the class doesn't import the correct package. I have imported java.util in both classes in question, which to my knowledge allows the use of the Comparator. I've experimented with writing the compareArtist method within the class that has the binary search call as well as in the "Song" class, which according to my homework assignment is where it should be. I've changed the constructor accordingly and the issue persists. Lastly, I've attempted to override the Comparator compare method by implementing Comparator in the Song class and creating my own method called "compare". This returns the same error. I've only moved to calling the comparator method something different than "compare" after finding several examples that do the same. Here is the relevant code for the class that calls the binary search that uses the comparator. This code also has a local version of the compareArtist method. While it is not being called currently, the code for this method is the same as the in the class Song, where I am trying to call it from. Thanks for any advice and insight. import java.io.*; import java.util.*; public class SearchByArtistPrefix { private Song[] songs; // keep a direct reference to the song array private Song[] searchResults; // holds the results of the search private ArrayList<Song> searchList = new ArrayList<Song>(); // hold results of search while being populated. Converted to searchResults array. public SearchByArtistPrefix(SongCollection sc) { songs = sc.getAllSongs(); } public int compareArtist (Song firstSong, Song secondSong) { return firstSong.getArtist().compareTo(secondSong.getArtist()); } public Song[] search(String artistPrefix) { String artistInput = artistPrefix; int searchLength = artistInput.length(); Song searchSong = new Song(artistInput, "", ""); Comparator<Song> compare = new Song.compareArtist(); int search = Arrays.binarySearch(songs, searchSong, compare);

  • Can SpriteBatch be used to fill a polygon with a texture?

    - by can poyrazoglu
    I basically need to fill a texture into a polygon using the SpriteBatch. I've done some research but couldn't find anything useful except polygon triangulation method, which works well only with convex polygons (without diving into super math which is definitely not something I'm pretty good at). Are there any solutions for filling in a polygon in a basic way? I of course need something dynamic (I'll have a map editor that you can define polygons, and the game will render them (and collision detection will also use them but that's off topic), basically I can't accept solutions like "pre-calculated" bitmaps or anything like that. I need to draw a polygon with the segments provided, to the screen, using the SpriteBatch.

  • How to transform a vector<int> into a string?

    - by Legend
    I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?
