• Help with off-game tasks

  - by peoro

  I love writing video games for fun, and often do that. I noticed, anyway, that most of the times implementing the gameplay itself doesn't take too much time to me (maybe because I already did that plenty times and know what and how to do for most of the things), but when I try to implement off-game stuff I get lost. By off-game I mean what is not gameplay: menus, cutscenes between levels, world map to choose levels, saving and loading status, managing replays ... Only tried to write a few of these a few times, but always failed; that's why I never really completed and distributed a game. Are these common problems? And where should I start to do this? Where could I find some books/guides about such stuff?

• Removing the last digits in string [migrated]

  - by Ruriko

  I have a string that looks like this: [APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC)_20121104_032834 I want to remove the digits at the end of the string, basically the 16 digits at the end of the string. In the end it should look like this: [APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC) This is my code that I have written so far var str="[APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC)_20121104_032834"; var n=str.substr(1,74); document.write(n); The problem is the string will be different so each will have different amount of characters. So how I remove the digits at the end of the string in javascript?

• Searchability and Indexability in Silverlight Sites

  I got a question from a friend last week that I thought would be a great question to post the answer to about Searchability and Indexability with Silverlight apps. Here is the question, "I have created a site and I followed the approach something like this : I have created 5 projects for five pages and added the five xap in the main SilverlightProject. and then I have write the code something like this for each menu buttons : HtmlPage.Window.Navigate(new Uri("/Default.aspx",urikind.relative) ; My...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Adserving Service for specific ads [on hold]

  - by JonoCoetzee

  I am looking into adserving services for a web application that is in development. I know there are the regulars like AdSense, DoubleClick, etc but the client wants the ability to sell of sections of the website to specific advertisers for specific campaigns. I would really prefer not to write this functionality (add, change, set duration, etc) from scratch so I'm looking for an adserving service that will allow specific ads to be uploaded and displayed to the end user. Preferably, one that integrates with a CDN of somesort. Are there services that offer this functionality?

• Best C++ Portable time library for game development

  - by Darkenor

  I'm venturing into the dark world of portable development and I'm looking for a nice library to keep track of system time for all game events. So far I've turned to trust boost and found: This boost library But I'm wondering if it there are some alternatives. I use boost a lot and (while I like it) I find that it sometimes takes me longer to figure out how to use the generic code than to write my own...not-so-generic code. (Ya, ya...I know. I should be less lazy). But anyway, advice appreciated! :)

• Creating blob properties with Entity Framework 4?

  - by David Veeneman

  I am creating an EF4 model-first application with a WPF UI. One of the controls on my UI is a RichTextDocument, which outputs a WPF FlowDocument. I can either serialize the FlowDocument to a byte array, or extract its XAML markup as a string. I would prefer to use binary serialization, if I can. Here are my questions: If I serialize to a byte array, how do I specify an entity property as a byte array in the EDM Designer? If I extract a XAML markup string, can I specify that the EDM Designer create the corresponding database column as a nvarchar(max) column? As to the second question, I assume I could always manually edit the MyModel.edmx.sql file to change the data type from nvarchar(4000) to nvarchar(max) before executing it, but I would like to know if it can be done in the Designer. Thanks for your help.

• Ruby on Rails deployment, on "thin" server with lot of attachments

  - by Horace Ho

  A lot of PDFs are stored inside MySQL as a BLOB field for each PDF file. The average file size is 500K each. The Rails app will stream the :binary data as file downloads, where there is a user click on the download link. Assume there is a maximum of 5 users downloading 5 PDFs concurrently, what kind of deployment setup parameters I should be aware of? e.g. for the case of thin: thin start --servers 3 whether --servers 3 is good enough (or 5 or more is needed) for the above example? The 2nd question is whether 'thin' a capable solution? Thanks!

• MATLAB matrix replacement assignment gives error

  - by Gulcan

  I tried to update some part of a matrix, I got the following error message: ??? Assignment has fewer non-singleton rhs dimensions than non-singleton subscripts My code tries to update some values of a matrix that represent a binary image. My code is as follows: outImage(3:5,2:4,1) = max(imBinary(3:5,2:4,1)); When I delete last parameter (1), this time I get the same error. I guess there is a mismatch between dimensions but I could not get it. outImage is a new object that is created at that time (I tried to create it before, but nothing changed). What may be wrong?

• Base64.encodeBase64URLSafeString() could not find method error in eclipse (Android project).

  - by jax

  I have an Android project that is using the Base64.encodeBase64URLSafeString commons method. The part that does the Base64 is in another java project. I have added the java project to the android project through the "Project" tab in the Build Path. I have already linked both projects to commons-codec thinking that this might be the problem but am still getting the following error in Eclipse. Both project have no errors. Could not find method org.apache.commons.codec.binary.Base64.encodeBase64URLSafeString, referenced from method com.mydomain.android.licensegenerator.client.LicenseLoader.doSha1AndBase64Encryption What might I be doing wrong?

• Compile Delphi component package (bpl) for different Delphi versions

  - by FractalizeR

  Hello. The situation is the following. Typically I use RAD Studio 2010 for Delphi development. I have some components I would like to redistribute in binary form (*.bpl without source). But I would like people to be able to use them despite of their Delphi version. But, for example, dcu files can be used only by compiler version, which generated them. Almost the same situation is with bpl files as I know. Every bpl file will require corresponding VCLXX.bpl library depending on Delphi version. How do I make my bpls, compiled in 2010 to be able to be used in Delphi7, 2007 etc? Is the only solution to have ALL Delphi versions installed and compile bpl files separately in each?

• Hough transformation for iris detection in opencv

  - by iva123

  Hi, I wrote the code for iris detection and it works well. Also I can crop the eye location of a face. Now I want to detect the iris of the crop image with applying the Hough transformation(cvHoughCircle). However when I try this procedure, the system is not able to find any circle on the image. Maybe, the reason is, there are noises in the image but I don't think it's the reason. So, how can I detect the iris ? I have the code of binary thresholding maybe I can use it, but I don't know how to do ?? If anyone helps I really appreciated. thx :)

• Is Programming == Math?

  - by moffdub

  I've heard many times that all programming is really a subset of math. Some suggest that OO, at its roots, is mathematically based. I don't get the connection. Aside from some obvious examples: using induction to prove a recursive algorithm formal correctness proofs functional languages lambda calculus asymptotic complexity DFAs, NFAs, Turing Machines, and theoretical computation in general the fact that everything on the box is binary In what ways is programming really a subset of math? I'm looking for an explanation that might have relevance to enterprise/OO development (if there is a strong enough connection, that is). Thanks in advance. Edit: as I stated in a comment to an answer, math is uber important to programming, but what I struggle with is the "subset" argument.

• Genetic algorithms

  - by daniels

  I'm trying to implement a genetic algorithm that will calculate the minimum of the Rastrigin functon and I'm having some issues. I need to represent the chromosome as a binary string and as the Rastrigin's function takes a list of numbers as a parameter, how can decode the chromosome to a list of numbers? Also the Rastrigin's wants the elements in the list to be -5.12<=x(i)<=5.12 what happens if when i generate the chromosome it will produce number not in that interval? I'm new to this so help and explanation that will aid me in understanding will be highly appreciated. Thanks.

• Ball to Ball Collision - Detection and Handling

  - by Simucal

  With the help of the Stack Overflow community I've written a pretty basic-but fun physics simulator. You click and drag the mouse to launch a ball. It will bounce around and eventually stop on the "floor". My next big feature I want to add in is ball to ball collision. The ball's movement is broken up into a x and y speed vector. I have gravity (small reduction of the y vector each step), I have friction (small reduction of both vectors each collision with a wall). The balls honestly move around in a surprisingly realistic way. I guess my question has two parts: What is the best method to detect ball to ball collision? Do I just have an O(n^2) loop that iterates over each ball and checks every other ball to see if it's radius overlaps? What equations do I use to handle the ball to ball collisions? Physics 101 How does it effect the two balls speed x/y vectors? What is the resulting direction the two balls head off in? How do I apply this to each ball? Handling the collision detection of the "walls" and the resulting vector changes were easy but I see more complications with ball-ball collisions. With walls I simply had to take the negative of the appropriate x or y vector and off it would go in the correct direction. With balls I don't think it is that way. Some quick clarifications: for simplicity I'm ok with a perfectly elastic collision for now, also all my balls have the same mass right now, but I might change that in the future. In case anyone is interested in playing with the simulator I have made so far, I've uploaded the source here (EDIT: Check the updated source below). Edit: Resources I have found useful 2d Ball physics with vectors: 2-Dimensional Collisions Without Trigonometry.pdf 2d Ball collision detection example: Adding Collision Detection Success! I have the ball collision detection and response working great! Relevant code: Collision Detection: for (int i = 0; i < ballCount; i++) { for (int j = i + 1; j < ballCount; j++) { if (balls[i].colliding(balls[j])) { balls[i].resolveCollision(balls[j]); } } } This will check for collisions between every ball but skip redundant checks (if you have to check if ball 1 collides with ball 2 then you don't need to check if ball 2 collides with ball 1. Also, it skips checking for collisions with itself). Then, in my ball class I have my colliding() and resolveCollision() methods: public boolean colliding(Ball ball) { float xd = position.getX() - ball.position.getX(); float yd = position.getY() - ball.position.getY(); float sumRadius = getRadius() + ball.getRadius(); float sqrRadius = sumRadius * sumRadius; float distSqr = (xd * xd) + (yd * yd); if (distSqr <= sqrRadius) { return true; } return false; } public void resolveCollision(Ball ball) { // get the mtd Vector2d delta = (position.subtract(ball.position)); float d = delta.getLength(); // minimum translation distance to push balls apart after intersecting Vector2d mtd = delta.multiply(((getRadius() + ball.getRadius())-d)/d); // resolve intersection -- // inverse mass quantities float im1 = 1 / getMass(); float im2 = 1 / ball.getMass(); // push-pull them apart based off their mass position = position.add(mtd.multiply(im1 / (im1 + im2))); ball.position = ball.position.subtract(mtd.multiply(im2 / (im1 + im2))); // impact speed Vector2d v = (this.velocity.subtract(ball.velocity)); float vn = v.dot(mtd.normalize()); // sphere intersecting but moving away from each other already if (vn > 0.0f) return; // collision impulse float i = (-(1.0f + Constants.restitution) * vn) / (im1 + im2); Vector2d impulse = mtd.multiply(i); // change in momentum this.velocity = this.velocity.add(impulse.multiply(im1)); ball.velocity = ball.velocity.subtract(impulse.multiply(im2)); } Source Code: Complete source for ball to ball collider. Binary: Compiled binary in case you just want to try bouncing some balls around. If anyone has some suggestions for how to improve this basic physics simulator let me know! One thing I have yet to add is angular momentum so the balls will roll more realistically. Any other suggestions? Leave a comment!

• Removing facebook API from my project

  - by mac_55

  I'm looking to remove the Facebook API from my iPhone project for 2 reasons: 1) My Facebook functionality is unfinished and I'd like to submit the app minus ALL of the FB functionality 2) I don't want to include the Facebook API as it contains encryption and I don't want to fill out additional forms etc. So. I need a simple way to remove all of my Facebook functionality and not put build the facebook API as part of the binary. I was thinking of commenting out my FB code... but how do I disconnect the FB api so that I can easily put it back in later? Thanks!

• How to pass string file path as HttpPostedfile to fileupload control?

  - by rahul

  Hi friends, I have got little tricky issue i.e I am using API of a product which has few methods for uploading image. The UI part of the product has one file upload control which takes files and convert that into binary and save it to database. In the coding part they are using one method where they send this fileupload.postedfile as one of the input parameter to the method. Now my requirement is, I have a directory where there are hundred of files which i have to send each file one by after another to this method as a input. Now i wish to know how to pass a file name as "HttpPostedFile" to that method as a parameter. I have no other option other than using that API (our clients requirement). Thanks

• Choosing between Berkeley DB Core and Berkeley DB JE

  - by zokier

  I'm designing a Java based web-app and I need a key-value store. Berkeley DB seems fitting enough for me, but there appears to be TWO Berkeley DBs to choose from: Berkeley DB Core which is implemented in C, and Berkeley DB Java Edition which is implemented in pure Java. The question is, how to choose which one to use? With web-apps scalability and performance is quite important (who knows, maybe my idea will become the next Youtube), and I couldn't find easily any meaningful benchmarks between the two. I have yet to familiarize with Cores Java API, but I find it hard to believe that it could be much worse than Java Editions, which seems to be quite nice. If some other key-value store would be much better, feel free to recommend that too. I'm storing smallish binary blobs, and keys probably will be hashes of the data, or some other unique id.

• A good machine learning technique to weed out good URLs from bad

  - by git-noob

  Hi, I have an application that needs to discriminate between good HTTP GET requests and bad. For example: http://somesite.com?passes=dodgy+parameter # BAD http://anothersite.com?passes=a+good+parameter # GOOD My system can make a binary decision about whether or not a URL is good or bad - but ideally I would like it to predict whether or not a previously unseen URL is good or bad. http://some-new-site.com?passes=a+really+dodgy+parameter # BAD I feel the need for a support vector machine (SVM) ... but I need to learn machine learning. Some questions: 1) Is an SVM appropriate for this task? 2) Can I train it with the raw URLs? - without explicitly specifying 'features' 3) How many URLs will I need for it to be good at predictions? 4) What kind of SVM kernel should I use? 5) After I train it, how do I keep it up to date? 6) How do I test unseen URLs again the SVM to decide whether it's good or bad?

• Is recursion ever faster than looping?

  - by Carson Myers

  I know that recursion is sometimes a lot cleaner than looping, and I'm not asking anything about when I should use recursion over iteration, I know there are lots of questions about that already. What I'm asking is, is recursion ever faster than a loop? To me it seems like, you would always be able to refine a loop and get it to perform more quickly than a recursive function because the loop is absent constantly setting up new stack frames. I'm specifically looking for whether recursion is faster in applications where recursion is the right way to handle the data, such as in some sorting functions, in binary trees, etc.
