• NetBeans 7.2 MinGW installing for OpenCV

  - by Gligorijevic

  i have installed minGW on my PC according to http://netbeans.org/community/releases/72/cpp-setup-instructions.html, and i have "restored defaults" using NetBeans 7.2 who has found all necessary files. But when I made test sample C++ app i got following error: c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -ladvapi32 c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -lshell32 c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -luser32 c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -lkernel32 collect2: ld returned 1 exit status make[2]: *** [dist/Debug/MinGW-Windows/welcome_1.exe] Error 1 make[1]: *** [.build-conf] Error 2 make: *** [.build-impl] Error 2 Can anyone give me a hand with installing openCV and minGW for NetBeans? generated Makefiles file goes like this: > # CMAKE generated file: DO NOT EDIT! > # Generated by "MinGW Makefiles" Generator, CMake Version 2.8 > > # Default target executed when no arguments are given to make. default_target: all .PHONY : default_target > > #============================================================================= > # Special targets provided by cmake. > > # Disable implicit rules so canonical targets will work. .SUFFIXES: > > # Remove some rules from gmake that .SUFFIXES does not remove.

• Add objects to Arraylist inside loop and get a list of them outside loops

  - by AgusDG

  Im already done with a method to do a shot on a board (bidimensional array). THe shot goes from the bottom to the top, and depending of the direction, it do bounces on the walls to get to the top. The thing is that I did the method to represent the trayectory with an 'x'. Now, I want to add the coordinates x and y of each position of the shot (b [x][y]) to and Arraylist of Objects Position. public Position(int row,int col) { this.row = row; this.col = col; } The thing is that the method uses a for loop and inside if loops, and I'll need to create the objects inside, and get them outside. I did that : public static ArrayList<Position> showTrayectory (char [][] b , int shotDirection, char bubble){ int row = 0, col = 0; ArrayList<Position> aListPos = new ArrayList<Position>(); Position positionsOfShot = new Position(row,col); START = ((RIGHT_WALL)/2) + shotDirection; boolean shotRight = false; if(shotDirection < 0) shotRight = false; else if(shotDirection > 0) shotRight = true; for(int y = BOTTOM,x = START ;y >= 0;y--) { if(!isOut(y,x) && !emptyCell(y,x)) break; if(x <= LEFT_WALL) shotRight = true; if(x >= RIGHT_WALL) shotRight = false; if(!isOut(y,x) && shotRight == true) { positionsOfShot = new Position(y,x); aListPos.add(positionsOfShot); b[y][x] = SHOT; ++x; } if(!isOut(y,x) && shotRight == false){ positionsOfShot = new Position(y,x); aListPos.add(positionsOfShot); b[y][x] = SHOT; --x; } } // The nested for loops below are for showing the positions // But I dont need it that way // I must get the trayectory from an ArrayList and print it from there for(int y=0;y < b.length;y++){ System.out.println(); for(int x=0;x < b[y].length;x++){ System.out.print(" "+b [y][x]+" "); } } System.out.println("\nTrayectory of the shot ["+shotDirection+"]"); System.out.println("Next bubble ["+bubble+"]"); for( Position ii : aListPos){ System.out.println("(" + positionsOfShot.getFila() + "," + positionsOfShot.getColumna()+")"); } return aListPos; } The sentence " b[y][x] = SHOT; " is still there, to see the proper trayectory of the shot (its not needed that way), but what I need, is getting the trayectory in an ArrayList, and print the trayectory from there. All that I get is a wrong position, and repeated during the number of positions the shot goes through. I need some help. I suppose the problem is that Im creating and adding Position Objects inside an ArrayList inside loops, but in a wrong way. I will need you to explain me how to do it properly ; ) Thanks in advance. I'll add the output for you see better what is that above haha *************************** y b y b g r b g o y g a a r y o y y r b y g r r o b o y y g b a r y r o a y y o o r r g r - - - x - - - - - - - - - x - - - - - - - - - x - - - - - - - - - x - - - - - - - - - x - - - - - - - - - x - - - - - - - x - - - - - - - x - - - - - - - x - - - Trayectory of the shot [1] Next bubble [y] (5,3) (5,3) (5,3) (5,3) (5,3) (5,3) (5,3) (5,3) (5,3) Action?

• [BEGINNER] Javascript Pop Ups

  - by user566312

  Hey All, My boss has asked for a page that will not change to have two timed pop ups load. I have found code and edited it to what I had thought it should do, but it is only loading the last onLoad event. I am a designer and I have helped with making webpages, but Javascript is so far outside of what I can understand. I have already learned how to use the single pop up and spent a whiiile learning the timeouts, but I cannot seem to get it to work with multiple popup functions. If you have a moment, would you take a look?

• Languages and VMs: Features that are hard to optimize and why

  - by mrjoltcola

  I'm doing a survey of features in preparation for a research project. Name a mainstream language or language feature that is hard to optimize, and why the feature is or isn't worth the price paid, or instead, just debunk my theories below with anecdotal evidence. Before anyone flags this as subjective, I am asking for specific examples of languages or features, and ideas for optimization of these features, or important features that I haven't considered. Also, any references to implementations that prove my theories right or wrong. Top on my list of hard to optimize features and my theories (some of my theories are untested and are based on thought experiments): 1) Runtime method overloading (aka multi-method dispatch or signature based dispatch). Is it hard to optimize when combined with features that allow runtime recompilation or method addition. Or is it just hard, anyway? Call site caching is a common optimization for many runtime systems, but multi-methods add additional complexity as well as making it less practical to inline methods. 2) Type morphing / variants (aka value based typing as opposed to variable based) Traditional optimizations simply cannot be applied when you don't know if the type of someting can change in a basic block. Combined with multi-methods, inlining must be done carefully if at all, and probably only for a given threshold of size of the callee. ie. it is easy to consider inlining simple property fetches (getters / setters) but inlining complex methods may result in code bloat. The other issue is I cannot just assign a variant to a register and JIT it to the native instructions because I have to carry around the type info, or every variable needs 2 registers instead of 1. On IA-32 this is inconvenient, even if improved with x64's extra registers. This is probably my favorite feature of dynamic languages, as it simplifies so many things from the programmer's perspective. 3) First class continuations - There are multiple ways to implement them, and I have done so in both of the most common approaches, one being stack copying and the other as implementing the runtime to use continuation passing style, cactus stacks, copy-on-write stack frames, and garbage collection. First class continuations have resource management issues, ie. we must save everything, in case the continuation is resumed, and I'm not aware if any languages support leaving a continuation with "intent" (ie. "I am not coming back here, so you may discard this copy of the world"). Having programmed in the threading model and the contination model, I know both can accomplish the same thing, but continuations' elegance imposes considerable complexity on the runtime and also may affect cache efficienty (locality of stack changes more with use of continuations and co-routines). The other issue is they just don't map to hardware. Optimizing continuations is optimizing for the less-common case, and as we know, the common case should be fast, and the less-common cases should be correct. 4) Pointer arithmetic and ability to mask pointers (storing in integers, etc.) Had to throw this in, but I could actually live without this quite easily. My feelings are that many of the high-level features, particularly in dynamic languages just don't map to hardware. Microprocessor implementations have billions of dollars of research behind the optimizations on the chip, yet the choice of language feature(s) may marginalize many of these features (features like caching, aliasing top of stack to register, instruction parallelism, return address buffers, loop buffers and branch prediction). Macro-applications of micro-features don't necessarily pan out like some developers like to think, and implementing many languages in a VM ends up mapping native ops into function calls (ie. the more dynamic a language is the more we must lookup/cache at runtime, nothing can be assumed, so our instruction mix is made up of a higher percentage of non-local branching than traditional, statically compiled code) and the only thing we can really JIT well is expression evaluation of non-dynamic types and operations on constant or immediate types. It is my gut feeling that bytecode virtual machines and JIT cores are perhaps not always justified for certain languages because of this. I welcome your answers.

• Why is the dropdown menu aligned to the left?

  - by fmz

  I am working on a dropdown navigation for a site and am having some trouble with the dropdown portion aligning with the parent category - it shifts all the way to the left. Here is the html: <ul class="dropdown"> <li><a href="#" id="home">Home</a></li> <li><a href="#" id="about">About Us</a> <ul class="sub-menu"> <li><a href="#">Our History</a></li> <li><a href="#">Our Process</a></li> <li><a href="#">Portfolio</a></li> <li><a href="#">Financing</a></li> <li><a href="#">Testimonials</a></li> <li><a href="#">Subcontractors</a></li> </ul> </li> <li><a href="#" id="personal">Personal Banking</a></li> <li><a href="#" id="commercial">Commercial Banking</a></li> <li><a href="#" id="service">Customer Service</a> <ul class="sub-menu"> <li><a href="#">Our History</a></li> <li><a href="#">Our Process</a></li> <li><a href="#">Portfolio</a></li> <li><a href="#">Financing</a></li> <li><a href="#">Testimonials</a></li> <li><a href="#">Subcontractors</a></li> </ul> </li> <li><a href="#" id="investors">Investor Relations</a></li> <li><a href="#" id="contact">Contact Us</a></li> </ul> Here is the CSS: ul.dropdown { position: relative; background: #4e8997; height: 40px; padding-left: 5px; } ul.dropdown li { float: left; zoom: 1; } ul.dropdown li a { display: block; margin-top: 5px; padding: .5em .6em; color: #fff; font: bold 14px "Helvetica Neue", Arial, Helvetica, Geneva, sans-serif; text-transform: uppercase; border: none; } ul.dropdown a:hover { background-color: #c29c5d; color: #fff; } ul.dropdown a:active { background-color: #c29c5d; color: #fff; } /* LEVEL TWO */ ul.dropdown ul { width: 200px; visibility: hidden; position: absolute; top:100%; left: 0; } ul.dropdown ul li { font: 13px "Helvetica Neue", Arial, Helvetica, Geneva, sans-serif; border-bottom: 1px solid #ccc; float: none; color: #fff; background-color: #c29c5d; height: 20px; } ul.dropdown ul li a { display: inline-block; } ul.dropdown ul li a:hover { background-color: #a2834d; color: #fff; height: 20px; } I tried changing the ul.dropdown ul to position relative, but that breaks the navigation. I would appreciate some help getting this corrected. Thanks.

• ASP.NET MVC 3 embrace dynamic type - CSDN.NET - CSDN Software Development Channel

  - by user559071

  About a decade ago, Microsoft will all bet on the WebForms and static types. With the complete package from scattered to the continuous development, and now almost every page can be viewed as its own procedure. Subsequent years, the industry continued to move in another direction, love is better than separation package, better than the late binding early binding to the idea. This leads to two very interesting questions. The first is the problem of terminology. Consider the original Smalltalk MVC model, view and controller is not only tightly coupled together, and usually in pairs. Most of the framework is that Microsoft, including the classic VB, WinForms, WebForms, WPF and Silverlight, they both use the code behind file to store the controller logic. But said "MVC" usually refers to the view and controller are loosely coupled framework. This is especially true for the Web framework, HTML form submission mechanism allows any views submitted to any of the controller. Since this article was mainly talking about Web technologies, so we need to use the modern definition. The second question is "If you're Microsoft, how to change orbit without causing too much pressure to the developer?" So far, the answer is: new releases each year, until the developers meet up. ASP.NET MVC's first product was released last March. Released in March this year, ASP.NET MVC 2.0. 3.0 RC 2 is currently in phase, expected to be released next March. December 10, Microsoft released ASP.NET MVC 3.0 Release Candidate 2. RC 2 is built on top of Microsoft's commitment to the jQuery: The default project template into jQuery 1.4.4, jQuery Validation 1.7 and jQuery UI. Although people think that Microsoft will focus shifted away from server-side controls to be a joke, but the introduction of Microsoft's jQuery UI is that this is the real thing. For those worried about the scalability of the developers, there are many excellent control can replace the session state. With SessionState property, you can tell the controller session state is read-only, read-write, or can be completely ignored in the. This site is no single server, but if a server needs to access another server session state, then this approach can provide a great help. MVC 3 contains Razor view engine. By default, the engine will be encoded HTML output, so that we can easily output on the screen the text of the original. HTML injection attacks even without the risk of encoded text can not easily prevent the page rendering. For many C # developers in the end do what is most shocking that MVC 3 for the controller and view and embrace the dynamic type. ViewBag property will open a dynamic object, developers can run on top of the object to add attributes. In general, it is used to send the view from the controller non-mode data. Scott Guthrie provides state of the sample contains text (such as the current time) and used to assemble the list box entries.

• Multiple data series in real time plot

  Hi, I'm kind of new to Python and trying to create a plotting app for values read via RS232 from a sensor. I've managed (after some reading and copying examples online) to get a plot working that updates on a timer which is great.

• [C#][XNA] Draw() 20,000 32 by 32 Textures or 1 Large Texture 20,000 Times

  - by Rudi

  The title may be confusing - sorry about that, it's a poor summary. Here's my dilemma. I'm programming in C# using the .NET Framework 4, and aiming to make a tile-based game with XNA. I have one large texture (256 pixels by 4096 pixels). Remember this is a tile-based game, so this texture is so massive only because it contains many tiles, which are each 32 pixels by 32 pixels. I think the experts will definitely know what a tile-based game is like. The orientation is orthogonal (like a chess board), not isometric. In the Game.Draw() method, I have two choices, one of which will be incredibly more efficient than the other. Choice/Method #1: Semi-Pseudocode: public void Draw() { // map tiles are drawn left-to-right, top-to-bottom for (int x = 0; x < mapWidth; x++) { for (int y = 0; y < mapHeight; y++) { SpriteBatch.Draw( MyLargeTexture, // One large 256 x 4096 texture new Rectangle(x, y, 32, 32), // Destination rectangle - ignore this, its ok new Rectangle(x, y, 32, 32), // Notice the source rectangle 'cuts out' 32 by 32 squares from the texture corresponding to the loop Color.White); // No tint - ignore this, its ok } } } Caption: So, effectively, the first method is referencing one large texture many many times, each time using a small rectangle of this large texture to draw the appropriate tile image. Choice/Method #2: Semi-Pseudocode: public void Draw() { // map tiles are drawn left-to-right, top-to-bottom for (int x = 0; x < mapWidth; x++) { for (int y = 0; y < mapHeight; y++) { Texture2D tileTexture = map.GetTileTexture(x, y); // Getting a small 32 by 32 texture (different each iteration of the loop) SpriteBatch.Draw( tileTexture, new Rectangle(x, y, 32, 32), // Destination rectangle - ignore this, its ok new Rectangle(0, 0, tileTexture.Width, tileTexture.Height), // Notice the source rectangle uses the entire texture, because the entire texture IS 32 by 32 Color.White); // No tint - ignore this, its ok } } } Caption: So, effectively, the second method is drawing many small textures many times. The Question: Which method and why? Personally, I would think it would be incredibly more efficient to use the first method. If you think about what that means for the tile array in a map (think of a large map with 2000 by 2000 tiles, let's say), each Tile object would only have to contain 2 integers, for the X and Y positions of the source rectangle in the one large texture - 8 bytes. If you use method #2, however, each Tile object in the tile array of the map would have to store a 32by32 Texture - an image - which has to allocate memory for the R G B A pixels 32 by 32 times - is that 4096 bytes per tile then? So, which method and why? First priority is speed, then memory-load, then efficiency or whatever you experts believe.

• BB Code Parser (in formatting phase) with jQuery jammed due to messed up loops most likely

  - by Oskar

  Greetings everyone, I'm making a BB Code Parser but I'm stuck on the JavaScript front. I'm using jQuery and the caret library for noting selections in a text field. When someone selects a piece of text a div with formatting options will appear. I have two issues. Issue 1. How can I make this work for multiple textfields? I'm drawing a blank as it currently will detect the textfield correctly until it enters the $("#BBtoolBox a").mousedown(function() { } loop. After entering it will start listing one field after another in a random pattern in my eyes. !!! MAIN Issue 2. I'm guessing this is the main reason for issue 1 as well. When I press a formatting option it will work on the first action but not the ones afterwards. It keeps duplicating the variable parsed. (if I only keep to one field it will never print in the second) Issue 3 If you find anything especially ugly in the code, please tell me how to improve myself. I appriciate all help I can get. Thanks in advance $(document).ready(function() { BBCP(); }); function BBCP(el) { if(!el) { el = "textarea"; } // Stores the cursor position of selection start $(el).mousedown(function(e) { coordX = e.pageX; coordY = e.pageY; // Event of selection finish by using keyboard }).keyup(function() { BBtoolBox(this, coordX, coordY); // Event of selection finish by using mouse }).mouseup(function() { BBtoolBox(this, coordX, coordY); // Event of field unfocus }).blur(function() { $("#BBtoolBox").hide(); }); } function BBtoolBox(el, coordX, coordY) { // Variable containing the selected text by Caret selection = $(el).caret().text; // Ignore the request if no text is selected if(selection.length == 0) { $("#BBtoolBox").hide(); return; } // Print the toolbox if(!document.getElementById("BBtoolBox")) { $(el).before("<div id=\"BBtoolBox\" style=\"left: "+ ( coordX + 5 ) +"px; top: "+ ( coordY - 30 ) +"px;\"></div>"); // List of actions $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_bold.png\" alt=\"B\" title=\"Bold\" /></a>"); $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_italic.png\" alt=\"I\" title=\"Italic\" /></a>"); } else { $("#BBtoolBox").css({'left': (coordX + 3) +'px', 'top': (coordY - 30) +'px'}).show(); } // Parse the text according to the action requsted $("#BBtoolBox a").mousedown(function() { switch($(this).children(":first").attr("alt")) { case "B": // bold parsed = "[b]"+ selection +"[/b]"; break; case "I": // italic parsed = "[i]"+ selection +"[/i]"; break; } // Changes the field value by replacing the selection with the variable parsed $(el).val($(el).caret().replace(parsed)); $("#BBtoolBox").hide(); return false; }); }

• Heading div images should be displayed at a lower depth

  - by Mack

  I have a webpage where the top 25% of the page is the heading(with images in it) & the rest of the page has the content. I am trying to get the heading div to display is pictures at a lower depth as the content div because currently the heading images overflow into the content div(intentionally) & when they do they mess up the positioning of the HTML elements in the content div. My code below should make the heading div display below the content div but it doesn't. Can you help me figure out why & how to fix it? My CSS: html, body { height: 100%; width: 100%; } body { background-color: RGB(255, 255, 255); margin: 20px; text-align: center; } #outerContainer { background-color: #DCFF9A; height: 100%; width: 100%; } #header { width: 1200px; height: 25%; background-color: blue; margin-left: auto; margin-right: auto; overflow: visible; z-index: -5; } #main { display: block; width: 1200px; height: 60%; background-color: blue; margin-left: auto; margin-right: auto; z-index: 5; } #navBar { float: left; height: 800px; width: 240px; background-color: red; } #content { float: left; height: 800px; width: 760px; background-color: yellow; } #kamaleiText { float: left; } #kamaleiLogo { float: left; padding-top: 30px; background-color: green; z-index: inherit; } #kamaleiLeaves { float: right; z-index: -2; background-color: cyan; z-index: inherit; } And my HTML is the following: <body> <div id="outerContainer"> <div id="header"> <img id="kamaleiLogo" src="" alt="Pic1" height="98%" width="300px"/> <!-- Knowtice if I set the width to something smaller then everything is spaced out correctly, so these elements are not being shown below others when they should be --> <img id="kamaleiLeaves" src="" alt="Pic2" height="300px" width="300px"/> </div> <br/> <div id="main"> <div id="navBar"> </div> <div id="content"> abcdef </div> </div> </div> </body>

• algorithm q: Fuzzy matching of structured data

  - by user86432

  I have a fairly small corpus of structured records sitting in a database. Given a tiny fraction of the information contained in a single record, submitted via a web form (so structured in the same way as the table schema), (let us call it the test record) I need to quickly draw up a list of the records that are the most likely matches for the test record, as well as provide a confidence estimate of how closely the search terms match a record. The primary purpose of this search is to discover whether someone is attempting to input a record that is duplicate to one in the corpus. There is a reasonable chance that the test record will be a dupe, and a reasonable chance the test record will not be a dupe. The records are about 12000 bytes wide and the total count of records is about 150,000. There are 110 columns in the table schema and 95% of searches will be on the top 5% most commonly searched columns. The data is stuff like names, addresses, telephone numbers, and other industry specific numbers. In both the corpus and the test record it is entered by hand and is semistructured within an individual field. You might at first blush say "weight the columns by hand and match word tokens within them", but it's not so easy. I thought so too: if I get a telephone number I thought that would indicate a perfect match. The problem is that there isn't a single field in the form whose token frequency does not vary by orders of magnitude. A telephone number might appear 100 times in the corpus or 1 time in the corpus. The same goes for any other field. This makes weighting at the field level impractical. I need a more fine-grained approach to get decent matching. My initial plan was to create a hash of hashes, top level being the fieldname. Then I would select all of the information from the corpus for a given field, attempt to clean up the data contained in it, and tokenize the sanitized data, hashing the tokens at the second level, with the tokens as keys and frequency as value. I would use the frequency count as a weight: the higher the frequency of a token in the reference corpus, the less weight I attach to that token if it is found in the test record. My first question is for the statisticians in the room: how would I use the frequency as a weight? Is there a precise mathematical relationship between n, the number of records, f(t), the frequency with which a token t appeared in the corpus, the probability o that a record is an original and not a duplicate, and the probability p that the test record is really a record x given the test and x contain the same t in the same field? How about the relationship for multiple token matches across multiple fields? Since I sincerely doubt that there is, is there anything that gets me close but is better than a completely arbitrary hack full of magic factors? Barring that, has anyone got a way to do this? I'm especially keen on other suggestions that do not involve maintaining another table in the database, such as a token frequency lookup table :). This is my first post on StackOverflow, thanks in advance for any replies you may see fit to give.

• Possible iphone animation timing/rendering bug?

  - by David

  Hi all, I have been working on an iphone apps for several weeks. Now I encounter an animation problem that I can't figure out how to resolve. Mayhbe you can help. Here is the details (a little long, bear with me): Basically the effect I want to achieve is, when user click a button, a loading view pops up, hiding the whole screen; and then the apps does a lot of heavy computation, which takes a few seconds. Once the computation is done, soem result views (something likes checkers on a checker board) are rendered under the loading view. Once all result views are rendered, I used animation animation to remove the loading view nand show the result views to the user. Here is what I do: when user click a button, run this code: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(loadingViewInserted:finished:context:)]; // use a really high index number so it will always on top [self.view insertSubview:loadingViewController.view atIndex:1000]; [UIView commitAnimations]; In the "loadingViewInserted" function, it calls another function doing the heavy computation work. Once the computation is done, a lot of result views (like checkers on a checker board) are rendered under the loading view. for(int colIndex = 1; colIndex <= result.columns; colIndex++) { for(int rowIndex = 1; rowIndex <= result.rows; rowIndex++) { ResultView *rv = [ResultView resultViewWithData:results[colIndex][rowIndex]]; [self.view addSubview:rv]; } } Once all result views are added, following animation is invoked to remove the loading view: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; [loadingViewController.view removeFromSuperview]; [UIView commitAnimations]; By doing this, most of the time (maybe 90%) it does exactly what I want. However, sometime I see some weird result: the loading view shows up first as expected, then before it disappears, some result views, which suppose to be under the loading view, suddenly appears on top of the loading view; and some of them are partial rendered. And then the loading view curled up, and everything looks normal again. The weird situation only lasts for less than a second, but already bad enough to screw up the UI. I have tried all different kinds of thing to fix this (using another thread to remove the loading view, make the loading view non-transparent), but none of them works. The only thing that makes a little better is, I hide all the result views first; after the last animation finished, in its call back, unhide all result views. But this loses the nice effect that when curling up the loading view, the results are already there. At this point, I really think this is a bug in iphone (I compile it with OS 3.0) OS. Or maybe you can point out what I have done wrong (or could do differently). (thanks for finishing this long post, :-) )

• Slow Javascript touch events on Android

  - by oneself

  I'm trying to write a simple html based drawing application (standalone simplified code attached bellow). I've tested this on the following devices: iPad 1 and 2: Works great ASUS T101 running Windows: Works great Samsung Galaxy Tab: Extremely slow and patchy -- unusable. Lenovo IdeaPad K1: Extremely slow and patchy -- unusable. Asus Transformer Prime: Noticeable lag compare with the iPad -- close to usable. The Asus tablet is running ICS, the other android tablets are running 3.1 and 3.2. I tested using the stock Android browser. I also tried the Android Chrome Beta, but that was even worse.

• MVC Datatables Dialog Not staying where dialog opens

  - by Anthoney Hanks

  I have created a view that displays a datatable with a clickable link that opens a jQuery UI dialog box. The users wanted a search options (8 dropdowns to narrow the search) at top of page, followed by the datatable with the 100 viewable records. If I scroll down the datatable to the bottom viewable record, click the link to open the dialog box. The dialog opens relative to the link clicked, but the focus go back to the top of the page which causes the user to have scroll back down to the dialog box. Ok, I thought I would just set the focus to the dialog box. BUt it is being ignored which make me think that this is something within the MVC realm. I even tried to wrap the focus inside a ready function thinking it would be one of the last things process. When I define the dailog, it is pretty basic. I even tried to set the position attribute, but it did not change the problem. Has someone had this problem and can send me in the right direction? View building the datatable: <table id="navDatatables"> <tbody> @foreach (var detailsVM in Model.DetailsVMs) { <tr> <td class="standardTable"> <a href="#" onclick="return PVE_UseConfig.Options(@detailsVM.ConfigVersionId, @Model.UseConfigModeId);" class="smallLink">Options</a> </td> <td class="standardTable"> <a href="@Url.Content(@detailsVM.ViewerUrl)" target="_blank">@detailsVM.ConfigName</a> </td> <td class="standardTable">@detailsVM.ConfigType</td> <td class="standardTable">@detailsVM.ConfigVersionState</td> <td class="standardTable">@detailsVM.Organization</td> <td class="standardTable">@detailsVM.ProcessSet</td> <td class="standardTable">@detailsVM.ConfigVersionCaption</td> <td class="standardTable">@detailsVM.ConfigId</td> <td class="standardTable">@detailsVM.ConfigVersionId</td> <td class="standardTable">@detailsVM.ConfigOwnerName</td> <td class="standardTable">@detailsVM.ConfigVersionLastModified</td> </tr> } </tbody> </table> Dialog box code: Options: function (configVersionId, useConfigModeId) { var output = '#modalDialog1'; var postData = { configVersionId: configVersionId, useConfigModeId: useConfigModeId }; $('#modalDialog1').dialog("destroy"); $.ajax({ url: PVE_RootUrl + 'UseConfig/Options', type: 'POST', async: false, data: postData, success: function (result) { $(output).html(result); }, error: function (jqXHR, textStatus, errorThrown) { var text = jqXHR.responseText; var from = text.search("<body>") + 6; var to = text.search("</body>") - 7; $(output).html(text.substring(from, to)); } }); $(output).dialog({ title: "Configuration Options", modal: true, height: 550, width: 600, resizable: false, draggable: false }); },

• Agile: User Stories for Machine Learning Project?

  - by benjismith

  I've just finished up with a prototype implementation of a supervised learning algorithm, automatically assigning categorical tags to all the items in our company database (roughly 5 million items). The results look good, and I've been given the go-ahead to plan the production implementation project. I've done this kind of work before, so I know how the functional components of the software. I need a collection of web crawlers to fetch data. I need to extract features from the crawled documents. Those documents need to be segregated into a "training set" and a "classification set", and feature-vectors need to be extracted from each document. Those feature vectors are self-organized into clusters, and the clusters are passed through a series of rebalancing operations. Etc etc etc etc. So I put together a plan, with about 30 unique development/deployment tasks, each with time estimates. The first stage of development -- ignoring some advanced features that we'd like to have in the long-term, but aren't high enough priority to make it into the development schedule yet -- is slated for about two months worth of work. (Keep in mind that I already have a working prototype, so the final implementation is significantly simpler than if the project was starting from scratch.) My manager said the plan looked good to him, but he asked if I could reorganize the tasks into user stories, for a few reasons: (1) our project management software is totally organized around user stories; (2) all of our scheduling is based on fitting entire user stories into sprints, rather than individually scheduling tasks; (3) other teams -- like the web developers -- have made great use of agile methodologies, and they've benefited from modelling all the software features as user stories. So I created a user story at the top level of the project: As a user of the system, I want to search for items by category, so that I can easily find the most relevant items within a huge, complex database. Or maybe a better top-level story for this feature would be: As a content editor, I want to automatically create categorical designations for the items in our database, so that customers can easily find high-value data within our huge, complex database. But that's not the real problem. The tricky part, for me, is figuring out how to create subordinate user stories for the rest of the machine learning architecture. Case in point... I know that the algorithm requires two major architectural subdivisions: (A) training, and (B) classification. And I know that the training portion of the architecture requires construction of a cluster-space. All the Agile Development literature I've read seems to indicate that a user story should be the "smallest possible implementation that provides any business value". And that makes a lot of sense when designing a piece of end-user software. Start small, and then incrementally add value when users demand additional functionality. But a cluster-space, in and of itself, provides zero business value. Nor does a crawler, or a feature-extractor. There's no business value (not for the end-user, or for any of the roles internal to the company) in a partial system. A trained cluster-space is only possible with the crawler and feature extractor, and only relevant if we also develop an accompanying classifier. I suppose it would be possible to create user stories where the subordinate components of the system act as the users in the stories: As a supervised-learning cluster-space construction routine, I want to consume data from a feature extractor, so that I can exist. But that seems really weird. What benefit does it provide me as the developer (or our users, or any other stakeholders, for that matter) to model my user stories like that? Although the main story can be easily divided along architectural-component boundaries (crawler, trainer, classifier, etc), I can't think of any useful decomposition from a user's perspective.

• Need help to properly remove duplicates in NHibernate

  - by Michael D. Kirkpatrick

  Here is the problem I am having. I have a database with over 100 records in it. I am paging through the data to get 9 results at a time. When I added a check to see if items are active, it caused the results to start doubling up. A little background: "Product" is the actual product line "ProductSkus" are the actual products that exist in the product line When there is more then 1 ProductSku within Product, it causes a duplicate entry to be returned. See the NHibernate Query below: result = this.Session.CreateCriteria<Model.Product>() .Add(Expression.Eq("IsActive", true)) .AddOrder(new Order("Name", true)) .SetFirstResult(indexNumber).SetMaxResults(maxNumber) // This part of the query duplicates the products .CreateAlias("ProductSkus", "ProdSkus", JoinType.InnerJoin) .Add(Expression.Eq("ProdSkus.IsActive", true)) .CreateAlias("ProductToSubcategory", "ProdToSubcat") .CreateAlias("ProdToSubcat.ProductSubcategory", "ProdSubcat") .Add(Expression.Eq("ProdSubcat.ID", subCatId)) // This part takes out the duplicate products - Removes too many items... // Turns out that with .SetFirstResult(indexNumber).SetMaxResults(maxNumber) // it gets 9 records back then the duplicates are removed. // Example: // Total Records over 100 // Max = 9 // 4 Duplicates removed // Yields 5 records when there should be 9 // Why??? This line is ran in NHibernate on the data after it has been extracted from the SQL server. .SetResultTransformer(new NHibernate.Transform.DistinctRootEntityResultTransformer()) .List<Model.Product>(); I added the DistinctRootEntityResultTransformer to clean up the duplicates. The problem is that it pulls 9 records back that contains duplicates. DistinctRootEntityResultTransformer then cleans up the duplicates in the 9 records. I am basically needing a distinct statement to be ran on the SQL server to begin with. However, distinct on SQL is not going to work since NHibernate by default wants to add every field from every table in the select part of the statement. I am only using the fields that belong to the root table to begin with (Model.Product). If I can tell NHibernate to not add the fields to the joined tables into the select part of the statement along with adding Distinct, it would work. I use NHibernare Profiler to see the actual query: SELECT top 9 this_.ID as ID351_3_, this_.Name as Name351_3_, this_.Description as Descript3_351_3_, this_.IsActive as IsActive351_3_, this_.ManufacturerID as Manufact5_351_3_, prodskus1_.ID as ID373_0_, prodskus1_.Description as Descript2_373_0_, prodskus1_.PartNumber as PartNumber373_0_, prodskus1_.Price as Price373_0_, prodskus1_.IsKit as IsKit373_0_, prodskus1_.IsActive as IsActive373_0_, prodskus1_.IsFeaturedProduct as IsFeatur7_373_0_, prodskus1_.DateAdded as DateAdded373_0_, prodskus1_.Weight as Weight373_0_, prodskus1_.TimesViewed as TimesVi10_373_0_, prodskus1_.TimesOrdered as TimesOr11_373_0_, prodskus1_.ProductID as ProductID373_0_, prodskus1_.OverSizedBoxID as OverSiz13_373_0_, prodtosubc2_.ID as ID362_1_, prodtosubc2_.MasterSubcategory as MasterSu2_362_1_, prodtosubc2_.ProductID as ProductID362_1_, prodtosubc2_.ProductSubcategoryID as ProductS4_362_1_, prodsubcat3_.ID as ID352_2_, prodsubcat3_.Name as Name352_2_, prodsubcat3_.ProductCategoryID as ProductC3_352_2_, prodsubcat3_.ImageID as ImageID352_2_, prodsubcat3_.TriggerShow as TriggerS5_352_2_ FROM Product this_ inner join ProductSku prodskus1_ on this_.ID = prodskus1_.ProductID and (prodskus1_.IsActive = 1) inner join ProductToSubcategory prodtosubc2_ on this_.ID = prodtosubc2_.ProductID inner join ProductSubcategory prodsubcat3_ on prodtosubc2_.ProductSubcategoryID = prodsubcat3_.ID WHERE this_.IsActive = 1 /* @p0 */ and prodskus1_.IsActive = 1 /* @p1 */ and prodsubcat3_.ID = 3 /* @p2 */ ORDER BY this_.Name asc If I hand modify the query and run it directly on the SQL server I get the result set I want (I removed all the extra fields in the select section and added DISTINCT): SELECT DISTINCT top 9 this_.ID as ID351_3_, this_.Name as Name351_3_, this_.Description as Descript3_351_3_, this_.IsActive as IsActive351_3_, this_.ManufacturerID as Manufact5_351_3_, FROM Product this_ inner join ProductSku prodskus1_ on this_.ID = prodskus1_.ProductID and (prodskus1_.IsActive = 1) inner join ProductToSubcategory prodtosubc2_ on this_.ID = prodtosubc2_.ProductID inner join ProductSubcategory prodsubcat3_ on prodtosubc2_.ProductSubcategoryID = prodsubcat3_.ID WHERE this_.IsActive = 1 /* @p0 */ and prodskus1_.IsActive = 1 /* @p1 */ and prodsubcat3_.ID = 3 /* @p2 */ ORDER BY this_.Name asc The big question I now must ask is... What must I change in the NHibernate Query to ultimately get the exact same result? Thanks in advance.

• Android Frame based animation memory problem

  - by madsleejensen

  Hi all Im trying to create a animation on top of a Camera Surface view. The animation if a box rotating, and to enable transparency i made a bunch of *.png files that i want to just switch out on top of the Camera view. The problem is Android wont allow me to allocate so many images (too much memory required) so the AnimationDrawable is not an option. Will i be able to allocate all the *.png bitmaps if i use OpenGL instead? then i would store all the *.png's as Textures and just make my own animation logic? is am i under the same restrictions there? Any ideas on how to solve this problem ? Ive made a Custom view that loads the image resource on every frame and discards it when next frame is to be displayed. But the performance is terrible. import android.app.Activity; import android.content.res.Resources; import android.graphics.drawable.Drawable; import android.os.SystemClock; import android.util.Log; import android.widget.ImageView; public class FrameAnimationView extends ImageView { private int mFramesPerSecond = 10; private int mTimeBetweenFrames = (1000 / mFramesPerSecond); private int mCurrentFrame = 1; private String[] mFrames; private Thread mAnimationThread; private Resources mResources; private String mIdentifierPrefix; private Activity mContext; private boolean mIsAnimating = false; private Integer[] mDrawableIndentifiers; public FrameAnimationView(Activity context, String[] frames) { super(context); mContext = context; mResources = context.getResources(); mFrames = frames; mIdentifierPrefix = context.getPackageName() + ":drawable/"; mDrawableIndentifiers = new Integer[frames.length]; } private void initAnimationThread() { mAnimationThread = new Thread(new Runnable() { @Override public void run() { while (mIsAnimating) { final int frameToShow = (mCurrentFrame - 1); //Log.e("frame", Integer.toString(frameToShow)); mContext.runOnUiThread(new Runnable() { @Override public void run() { if (mDrawableIndentifiers[frameToShow] == null) { String frameId = mFrames[frameToShow]; int drawableResourceId = mResources.getIdentifier(mIdentifierPrefix + frameId, null, null); mDrawableIndentifiers[frameToShow] = drawableResourceId; } Drawable frame = getResources().getDrawable(mDrawableIndentifiers[frameToShow]); setBackgroundDrawable(frame); if (mCurrentFrame < mFrames.length) { mCurrentFrame++; } else { mCurrentFrame = 1; } } }); try { Thread.sleep(mTimeBetweenFrames); } catch (InterruptedException e) { e.printStackTrace(); } } } }); } public void setFramesPerSecond(int fps) { mFramesPerSecond = fps; mTimeBetweenFrames = (1000 / mFramesPerSecond); } public void startAnimation() { if (mIsAnimating) return; mIsAnimating = true; initAnimationThread(); mAnimationThread.start(); } public void stopAnimation() { if (mIsAnimating) { Thread oldThread = mAnimationThread; mAnimationThread = null; oldThread.interrupt(); mIsAnimating = false; } } }

• JQuery help, How to Hide all button in JQuery

  - by user303518

  Hi guys, I'm trying to make a request/reply section in my project. I want to achieve these functionality in that code (that I'm not able to implement; so guys please help me out): 1 When user click on reply button; other reply area(text-area +button) should be hide (means at a time only one reply area should be visible to the user). 2 when user click on reply button text-area will focus and page will slide down (suppose user reply 10 comment focus will automatically set to the 10 number text area and page will slide down to that position accordingly). Here is my so far code guys: //method call on the click of reply link. function linkReply_Clicked(issueId) { Id = issueId; textId = "text_" + issueId + count; btnReply = "btnReply_" + issueId + count; btnCancel = "btnCancel_" + issueId + count; var textareasArray = document.getElementsByTagName("textarea"); var btnArray = document.getElementsByTagName("input"); for (i = 0; i < textareasArray.length; i++) { textareasArray[i].style.display = "none"; btnArray[i].style.display = "none"; } var str = "<table cellpadding='3' cellspacing='0' width='58%'>"; str += "<tr><td valign='top' align='left'>"; str += "<textarea id=" + textId + " rows='5' cols='60'></textarea>"; str += "</td></tr>"; str += "<tr><td valign='top' align='right'>"; str += "<input id=" + btnReply + " type='button' onclick='btnReply_Clicked(Id ,textId)' value='Reply' />&nbsp;"; str += "<input id=" + btnCancel + " type='button' onclick='btnCancel_Clicked(Id ,textId)' value='Cancel' />&nbsp;"; str += "</td></tr>"; str += "</table>"; document.getElementById("divOuter_" + issueId).innerHTML = str; $("#" + textId + "").focus(); } // submit user reply and try to hide that reply area. function btnReply_Clicked(issueId, textID) { var comment = document.getElementById(textID).value; if (comment != '') { $.getJSON("/Issue/SaveComment", { IssueId: issueId, Comment: comment }, null); $("#text_" + issueId + count).hide(); $("#btnReply_" + issueId + count).hide(); $("#btnCancel_" + issueId + count).hide(); document.getElementById(textID).value = ''; count = count + 1; } } // cancel user reply and try to hide that reply area. function btnCancel_Clicked(issueId, textId) { $("#text_" + issueId + count).hide(); $("#btnReply_" + issueId + count).hide(); $("#btnCancel_" + issueId + count).hide(); document.getElementById(textId).value = ''; count = count + 1; }

• Dynamically alter outter div as inner one gets bigger.

  - by Razor Storm

  I have two divs, one inside another. The outter one is called #wrapper, while the inner one is called #pad. Now #pad allows user input, and I have a javascript (jQuery) function that changes the content of #pad based on what the user input is. Sometimes, because of this function, #pad's content will cause the div to become more elongated than before. Now obviously I would wish for #wrapper to grow longer as well to accommodate this change in #pad's length. However, this does not occur. #wrapper { clear:both; padding-top:0.5em; /*padding-left:50px;*/ height: 100%; background-color: rgba(255,255,255,0.4); -moz-border-radius: 20px 20px 0px 0px; -webkit-border-radius: 20px 20px 0px 0px; border-radius: 20px 20px 0px 0px; } #pad { margin-top: 25px; -moz-border-radius: 5px; border: solid 1px #DDD; margin-left:25px; padding-left:25px; margin-right:25px; padding-right:25px; margin-bottom:2em; } This is the javascript function: function preview() { var id1=$("#input1").val(); var id2=$("#input2").val(); var id3=$("#input3").val(); var id4=$("#input4").val(); var id5=$("#input5").val(); if(id1!= null && id1!="") { if( $("#preview1").attr("src")!=id1) { $("#preview1").attr("src",id1); $("#preview1").fadeIn("slow"); } } else { $("#preview1").attr("src",""); $("#preview1").fadeOut("slow"); } if(id2!= null && id2!="") { if( $("#preview2").attr("src")!=id2) { $("#preview2").attr("src",id2); $("#preview2").fadeIn("slow"); } } else { $("#preview2").attr("src",""); $("#preview2").fadeOut("slow"); } if(id3!= null && id3!="") { if( $("#preview3").attr("src")!=id3) { $("#preview3").attr("src",id3); $("#preview3").fadeIn("slow"); } } else { $("#preview3").attr("src",""); $("#preview3").fadeOut("slow"); } if(id4!= null && id4!="") { if( $("#preview4").attr("src")!=id4) { $("#preview4").attr("src",id4); $("#preview4").fadeIn("slow"); } } else { $("#preview4").attr("src",""); $("#preview4").fadeOut("slow"); } if(id5!= null && id5!="") { if( $("#preview5").attr("src")!=id5) { $("#preview5").attr("src",id5); $("#preview5").fadeIn("slow"); } } else { $("#preview5").attr("src",""); $("#preview5").fadeOut("slow"); } setTimeout("preview()",1000); $("#wrapper").attr("height",$(document).attr("height")); } http://surveys.mylifeisberkeley.com/
