• How to handle animations?

  - by Bane

  I am coding a simple 2D engine to be used with HTML5. I already have classes such as Picture, Scene, Camera and Renderer, but now I need to work on Animations. Picture is basocally a wrapper for a normal image object, with it's own draw method, but this is unrelated, I'm interested in how animation in 2D games is usually done. What I planned to do, is to have the Animation class as well act like a wrapper for a few image objects, and then have methods such as getCurrentImage, next and animate (which would use intervals to quickly change the current image). I meant to feed the animation a couple of PNG's at inicialisation. Is quickly swapping PNG images acceptable for 2D animation? Are there some standard ways of doing this, or are there flaws in my ways?

• Execure a random command from .txt file?

  - by Alberto Burgos

  I have a Ubuntu server, and I'm trying to print a Twitter quote using the app "twidge". So I made a list of tweets on a .txt file. I want to print one tweet (per line) from that file and send it to Twitter via twidge (or what ever other method was possible). I can print a random phrase with shuf: shuf -n 1 /var/www/tweets.txt and it works. It sends me back one of the tweets, but, it does not send it to Twitter, even if the "in line" phrase is a command. i.e: twidge update "bla bla bla" It just prints on the screen, but don't send it to Twitter. I tried turning the .txt to .sh, but don't work... any idea? by the way, i want to use it with crontab, something like this: 15 * * * * shuf -n 1 /var/www/tweets.txt

• Creating widgets using GtkBuilder

  - by user72943

  I am using Glade to design a Box with widgets and then load these widgets into my UI at run-time. To create each Box with widgets at run-time, I create a new GtkBuilder, call add_from_string passing in the text from the .ui file Glade creates, and then use the object returned from get_object("box1") in the UI. I know I could create the widgets with code, but for now, I'd like to use the .ui files Glade creates. It seems inefficient though to instantiate a new GtkBuilder object and the wasted Window object for every Box I want to create. Is there a more efficient method to load .ui files without creating a new GtkWidget object and wasted Window object? Thanks, Vance

• How to get notfications of ppa updates?

  - by maxschlepzig

  How can I get notified of updates to a certain PPA? For example when I am interested in new package versions of a certain package in a certain PPA? If a user has the package in question installed and is using the default desktop, she probably get notified via an icon in the traybar or something like that. But I am searching for a method which works even when the package is not installed (and without gnome). It should be reliable and prompt. Does launchpad provides some RSS/Atom-Feed features for PPAs? Or email notifications? (As a sidenote: I am surprised that even with my own PPA I only get an upload notification via mail - but no notification when the binary package is finished.)

• Calculating vertex normals on the GPU

  - by Etan

  I have some height-map sampled on a regular grid stored in an array. Now, I want to use the normals on the sampled vertices for some smoothing algorithm. The way I'm currently doing it is as follows: For each vertex, generate triangles to all it's neighbours. This results in eight neighbours when using the 1-neighbourhood for all vertices except at the borders. +---+---+ ¦ \ ¦ / ¦ +---o---+ ¦ / ¦ \ ¦ +---+---+ For each adjacent triangle, calculate it's normal by taking the cross product between the two distances. As the triangles all have the same size when projected on the xy-plane, I simply average over all eight normals then and store it for this vertex. However, as my data grows larger, this approach takes too much time and I would prefer doing it on the GPU in a shader code. Is there an easy method, maybe if I could store my height-map as a texture?

• Existing Instance, Shiny New Disks

  - by merrillaldrich

  Migrating an Instance of SQL Server to New Disks I get to do something pretty entertaining this week – migrate SQL instances on a 2008 cluster from one disk array to another! Zut alors! I am so excited I can hardly contain myself, so let’s get started. (Only a DBA could love this stuff, am I right? I know.) Anyway, here’s one method of many to migrate your data. Assumption : this is a host-based migration, which just means I’m using the Windows file system to push the data from one set of SAN disks...(read more)

• How do I reset my Ubuntu user password?

  - by Myself

  I lost my Ubuntu user account password... I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type "passwd [username]" and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

• RESTful API design - should a PUT return related data?

  - by alexmcroberts

  I have an API which allows a user to update their system status; and a separate call to retrieve system status updates from other users. Would it make sense to unify them under a PUT request where a user would request a PUT update with their own status update, and they would receive the status updates of other users? My solution would allow the PUT request to call the GET request method internally. The reason behind this is that when a user updates their system status they should be informed of other users status immediately, and I don't feel that having 2 seperate requests is necessary - and should be optional. I intend to keep the GET request for other users status as a status update for a user is not necessarily required in order to retrieve other users status', but once they update their own status is it vital that they get information about other users.

• Can someone explain how this IOS Pan Gesture Recognition works? [on hold]

  - by user79894

  It is ios app using Pan Gesture Recognizer It works great, but I didn't get it. I wanna do some changes if the dragged UIView reaches a specific position it would call another method. Any comments are appreciated. - (IBAction)handlePan1:(UIPanGestureRecognizer *)recognizer { CGPoint translation = [recognizer translationInView:self.view]; recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x, recognizer.view.center.y + translation.y); [recognizer setTranslation:CGPointMake(0, 0) inView:self.view]; /* [x1 setText:[NSString stringWithFormat: @"%.2f", recognizer.view.center.x]]; [y1 setText:[NSString stringWithFormat: @"%.2f", recognizer.view.center.y]]; [x2 setText:[NSString stringWithFormat: @"%.2f", translation.x]]; [y2 setText:[NSString stringWithFormat: @"%.2f", translation.y]];*/ }

• Castle Windsor Dependency Injection with MVC4

  - by Renso

  Problem:Installed MVC4 on my local and ran a MVC3 app and got an error where Castle Windsor was unable to resolve any controllers' constructor injections. It failed with "No component for supporting the service....".As soon as I uninstall MVC4 beta, the problem vanishes like magic?!I also tried to upgrade to NHibernate 3 and Castle and Castle Windsor to version 3 (from version 2), but since I use Rhino Commons, that is not possible as the Rhino Commons project looks like is no longer supported and requests to upgrade it to work with NHibernate version 3 two years ago has gone unanswered. The problem is that Rhino Commons (the older version) references a method in Castle version 2 that has been depreciated in version 3: "CreateContainer("windsor.boo")' threw an exception of type 'System.MissingMethodException."Hope this helps anyone else who runs into this issue. Btw I used NuGet package manager to install the correct packages so I know that is not the issue.

• Target tracking with a small delay (actionscript 3.0)

  - by John Dodson

  I'm having trouble thinking of a good method to track my character with an enemy attack. Of course, I don't want the attack to track my character's current position; I want it to track where the character was about 1 second before (so you can move around and make the attack miss and loop around you sort of a thing). The general structure of my game uses a timer to update all of my events. I have a timer going off every 25 milliseconds that updates everything, including my player's position and the enemies position. Right now I just have the enemy attack directly targeting my character....which works fine except that it's impossible to escape =p. Let me know if I didn't supply enough details. My approach was going to basically be get my character's position from about 1 second ago, then have the enemy target that position, the only problem is I can't think of a good way to get my character's position from previous times. Thanks for the help!

• Is it a good idea to appoint one of the scrum team member or scrum master as Product Owner?

  - by Sandy

  Lately we had a project, in which client was busy touring. As usual scrum team was formed, management decided to appoint our analyst as Product owner since Client won’t be able to participate actively. Analyst was the one who worked closely with client for requirement analysis and specification drafting. Client doesn’t have the time to review first two releases. Everything went smoothly until, client saw third release; he wasn’t satisfied with some functionalities, and those was introduced by make shift Product Owner (our analyst). We were told to wait till design team finished mock-up of all pages and client checked each one and approved to continue working. Scrum team is there, but no sprints – we finished work almost like classic waterfall method. Is it a good idea to appoint scrum team member or master as product owner? Do we need to follow scrum in the absence of client/product owner participation?

• How to document experimental or incomplete APIs like @deprecated?

  - by Michael Levy

  Is there a good term that is similar but different than "deprecate" to mean that a method or API is in the code base but should not be used because its implementation is not complete or will likely change? (Yeah, I know, those methods shouldn't be public, yada yada yada. I didn't create my situation, I'm just trying to make the best of it.) What do people suggest? Experimental, Incomplete, something else? If I'm building javadoc documentation for this API that is still in flux, should I use the @deprecated tag or is there a better convention? To me @deprecated implies that this API is old and a newer preferred mechanism is available. In my situation, there is no alternative, but some of the methods in the API are not finished and so should not be used. At this point I cannot make them private, but I'd like to put clear warnings in the docs.

• Making an efficient collision detection system

  - by Sri Harsha Chilakapati

  I'm very new to game development (just started 3 months ago) and I'm learning through creating a game engine. It's located here. In terms of collision, I know only brute-force detection, in which case, the game slows down if there are a number of objects. So my question is How should I program the collisions? I want them to happen automatically for every object and call the object's collision(GObject other) method on each collision. Are there any new algorithms which can make this fast? If so, can anybody shed some light on this topic?

• Review of Agile Project Management Software

  - by John K. Hines

  Bright Green Projects have an admittedly older blog post entitled Review of Agile Project Management Software | Scrum Kanban Methodology. Since I haven't had time to review Scrum project management tools in quite awhile, it was nice to find a write-up that's as succinct as this one. The thing I like the best about Bright Green's site, besides the product, is the vocabulary they use to describe Agile software development. For example, the couple Scrum with the development methodology they're using (Lean Kanban). Many organisations simply say they're using Scrum, which itself doesn't proscribe any engineering practices. It would add some clarity for teams to adopt the Scrum-Method terminology. At least then you could know if you're walking into a Scrum-Chaos situation.

• Managing multiple references of the same game entity in different places using IDs

  - by vargonian

  I've seen great questions on similar topics, but none that addressed this particular method: Given that I have multiple collections of game entities in my [XNA Game Studio] game, with many entities belonging to multiple lists, I'm considering ways I could keep track of whenever an entity is destroyed and remove it from the lists it belongs to. A lot of potential methods seem sloppy/convoluted, but I'm reminded of a way I've seen before in which, instead of having multiple collections of game entities, you have collections of game entity IDs instead. These IDs map to game entities via a central "database" (perhaps just a hash table). So, whenever any bit of code wants to access a game entity's members, it first checks to see if it's even in the database still. If not, it can react accordingly. Is this a sound approach? It seems that it would eliminate many of the risks/hassles of storing multiple lists, with the tradeoff being the cost of the lookup every time you want to access an object.

• How do I find the closest points(thereby forming a polygon) enclosing a particular point?(see image)

  - by nilspin

  I am working with a game engine, and my task is to add code for simulating fracture of rigid meshes. Right now I'm only working on breaking a cube. I am using Voronoi's algorithm to make a (realistic)fractured shard and I am using the half-plane method to generate a voronoi cell. Now the way I do this is for every seed point, I make planes that are perpendicular bisector planes(the straight black lines in the image) with rest of the seed points and I calculate the intersections of all these planes to give me distinct points(all the orange dots). I've gotten this far. Out of all these calculated intersection points, I only need the ones that are closest and enclosing the seed point(the points encircled in red) and I need to discard all the rest. Information that I have : 1) Plane equations of all planes(defined by normalized normal vectors and their distance from origin) 2) Points of intersection(that I've calculated) Can anybody help me find out how I can find the points encircled in red? Thanks.

• Structuring game world entities and their rendering objects

  - by keithjgrant

  I'm putting together a simple 2d tile-based game. I'm finding myself spinning circles on some design decisions, and I think I'm in danger of over-engineering. After all, the game is simple enough that I had a working prototype inside of four hours with fewer than ten classes, it just wasn't scalable or flexible enough for a polished game. My question is about how to structure flow of control between game entity objects and their rendering objects. Should each renderer have a reference to their entity or vice-versa? Or both? Should the entity be in control of calling the render() method, or be completely oblivious? I know there are several valid approaches here, but I'm kind of feeling decision paralysis. What are the pros and cons of each approach?

• Create an Asynchronous JAX-WS Web Service and call it from Oracle BPEL 11g

  - by Bob Webster

  This posting is the result of a simple requirement to take an existing JAX-WS Web service,convert it to be asynchronous and call it from Oracle BPEL 11g It turned out that this is not a trivial task... BPEL has some very specific expectations about the WSDL for an asynchronous process. One approach is to develop the service starting from a WSDL document that meets BPEL's requirements. This is possible but requires considerable WSDL authoring skills. The other approach is to modify the WSDL generated by Web Service Annotations in Java code (Bottom up development) and instruct JAX-WS to use that WSDL instead of dynamically generating one from annotations. This is the approach taken in this article. This posting details how to: Modify a JAX-WS Web Service developed using a "Bottom up " approach to have an asynchronous method and callback. Call the Asynchronous Service from Oracle BPEL 11g. Read the full posting here.

• Sending state diffs (deltas) and unreliable connections

  - by spaceOwl

  We're building a realtime multiplayer game, in which each player is responsible for reporting its state on every iteration of the game loop. The state updates are broadcasted using unreliable UDP. To minimize state data sending, we've come up with a system that will send only deltas (whatever state data that was changed). This method however is flawed, since a lost packet will mean that other players will not receive the delta, making the game behave in an unexpected way. For example: Assume that state is comprised of: { positionX, positionY, health } Frame 1 - positionX changed --> send a packet with positionX only. Frame 2 - health changed // lost ! Frame 3 - positionY changed --> send a packet with positionY only. // Other players don't know about health change. How can one overcome this issue then? sending the entire data is not always feasible.

• What are the basic skills a BEGINNING JavaScript programmer should have?

  - by Sanford

  In NYC, we are working on creating a collaborative community programming environment and trying to segment out software engineers into differing buckets. At present, we are trying to define: Beginners Intermediates Advanced Experts (and/or Masters) Similar to an apprenticeship, you would need to demonstrate specific skills to achieve different levels. Right now, we have identified Beginner programming skills as: Object - method, attributes, inheritance Variable - math, string, array, boolean - all are objects Basic arithmetic functions - precedence of functions String manipulation Looping - flow control Conditionals - boolean algebra This is a first attempt, and it is a challenge since we know the natural tension between programming and software engineering. How would you create such a skills-based ranking for JavaScript in this manner? For example, what would be the Beginner Javascript skills that you would need to have to advance to the Intermediate Training? And so on.

• Installing Ubuntu on btrfs over multiple drives

  - by Tom Ato

  When I installed Ubuntu 13.04, I managed to combine a couple of outdated askubuntu answers, as well as some of the btrfs documentation in order to figure out how to install Ubuntu over two SSDs using a single btrfs partition (I think /boot was on a small ext4 partition). I want to install Ubuntu 13.10 in a similar way, using a single btrfs partition striping data over the two SSDs, but I don't feel comfortable synthesizing a method that I am sure will work with current software. What is the best way to partition and install Ubuntu over two SSDs using btrfs, in an effectively RAID 0 way?

• How can a collection class instantiate many objects with one database call?

  - by Buttle Butkus

  I have a baseClass where I do not want public setters. I have a load($id) method that will retrieve the data for that object from the db. I have been using static class methods like getBy($property,$values) to return multiple class objects using a single database call. But some people say that static methods are not OOP. So now I'm trying to create a baseClassCollection that can do the same thing. But it can't, because it cannot access protected setters. I don't want everyone to be able to set the object's data. But it seems that it is an all-or-nothing proposition. I cannot give just the collection class access to the setters. I've seen a solution using debug_backtrace() but that seems inelegant. I'm moving toward just making the setters public. Are there any other solutions? Or should I even be looking for other solutions?
