• Does Hauppauge WinTV HVR-900 (r2) [USB ID 2040:6502] work with ubuntu 12.04 LTS?

  - by nightfly

  I have this DVB+Analog usb tv tuner Hauppauge WinTV HVR-900 (r2) [USB ID 2040:6502]. This used to work under ubuntu 10.04 LTS. But in 12.04 there seems to be a problem. I have linux-firmware-nonfree and ivtv-utils installed. I am running Ubuntu 12.04.1 LTS 64 bit with all updates installed and the default unity environment. When I run mplayer tv:// -tv driver=v4l2:device=/dev/video1:input=1:norm=PAL I get a solid green screen and no picture. Here input 1 is the composite input of the card. MPlayer svn r34540 (Ubuntu), built with gcc-4.6 (C) 2000-2012 MPlayer Team mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support.

• Collapsing Bookmarks

  - by Tim Dexter

  I said I would tackle documenting some of the new features in the 10.1.3.4.1 roll up patch I mentioned last week. With the patch you can now set the default state of bookmarks (if you create them) in your PDF outputs. If your users prefer to see them all collapsed to the base level or may be collapsed to the second level to ease navigation; whatever they need. Its another opportunity for you to look like a star! You of course need to start with a table of contents; then add the convert|copy to bookmarks command. You can then add the new collapse command to set the appropriate level in the bookmarks. <?copy-to-bookmark:?> <?collapse-bookmark:show;2?> <<< Table of Contents >>> <?end convert-to-bookmark?> The command allows you to expand or collapse the bookmarks as you need. Of course you will know how many levels you will have in the final output document. The command takes the form: <?collapse-bookmark:show|hide;level int?> Some examples <?collapse-bookmark:hide;1?> <?collapse-bookmark:hide;2?> <?collapse-bookmark:hide;3?> Sample template and data here. Dont forget you need that 10.1.3.4.1 roll up!

• My Windows 8 App in Windows Store

  - by Stephen.Walther

  Finally, you have a good reason to upgrade to Windows 8! My Brain Eaters app was just accepted into the Windows Store. Just in time for Halloween! The Brain Eaters app is a sample app from my soon to be released book Windows 8 Apps with HTML5 and JavaScript. The game illustrates several important programming concepts which you need when building Windows 8 games with JavaScript such as using HTML5 Canvas and the new requestAnimationFrame() method. If you are looking for Halo or Call of Duty then you will be disappointed. If you are looking for PAC-MAN then you will be disappointed. I created the simplest arcade game that I could imagine so I could explain it in the book. All of the code for the game is included with the book. The goal of the game is to eat the food pellets while avoiding the zombies while running around a maze. Every time you get eaten by a zombie, you can hear my six year old son saying “Oh No!”. Here’s the link to the game: http://apps.microsoft.com/webpdp/app/brain-eaters/e283c8d0-1fed-4b26-a8bf-464584c9de6d

• Which is a better practice - helper methods as instance or static?

  - by Ilian Pinzon

  This question is subjective but I was just curious how most programmers approach this. The sample below is in pseudo-C# but this should apply to Java, C++, and other OOP languages as well. Anyway, when writing helper methods in my classes, I tend to declare them as static and just pass the fields if the helper method needs them. For example, given the code below, I prefer to use Method Call #2. class Foo { Bar _bar; public void DoSomethingWithBar() { // Method Call #1. DoSomethingWithBarImpl(); // Method Call #2. DoSomethingWithBarImpl(_bar); } private void DoSomethingWithBarImpl() { _bar.DoSomething(); } private static void DoSomethingWithBarImpl(Bar bar) { bar.DoSomething(); } } My reason for doing this is that it makes it clear (to my eyes at least) that the helper method has a possible side-effect on other objects - even without reading its implementation. I find that I can quickly grok methods that use this practice and thus help me in debugging things. Which do you prefer to do in your own code and what are your reasons for doing so?

• any online service and/or application to develop a story line for an adventure game?

  - by Gajet

  I with a bunch of friend were talking about an adventure game. there will be too many possibilities in the game and the player can pick from wide varity of choices at each stage to do somthing. there will be consequences for each decision and they may or may not end the story. the result would be somthing like (picture from flashforward series S01E17)or if any of you watched hereos season 1 there is also similar time lines represented as strings in isaac mandez workshop. sorry for bad quality examples but right now I can't think of any better one. do you know any website or application which we can use to create the timeline? these features the least required ones: the ability to represent events as boxes. the ability to connect distant events to each other. the ability to move events on a scene freely the ability to expand the scene easily there should be some color options for the lines representing connections between events easily shareing the idea with one another it's much more better to have a WYSIWYG editor easily explore in the large scene of events in the end if you know any application which could let me create a board just like the one in my sample picture and share it whith other freinds it could help us a lot.

• Decorator not calling the decorated instance - alternative design needed

  - by Daniel Hilgarth

  Assume I have a simple interface for translating text (sample code in C#): public interface ITranslationService { string GetTranslation(string key, CultureInfo targetLanguage); // some other methods... } A first simple implementation of this interface already exists and simply goes to the database for every method call. Assuming a UI that is being translated at start up this results in one database call per control. To improve this, I want to add the following behavior: As soon as a request for one language comes in, fetch all translations from this language and cache them. All translation requests are served from the cache. I thought about implementing this new behavior as a decorator, because all other methods of that interface implemented by the decorater would simple delegate to the decorated instance. However, the implementation of GetTranslation wouldn't use GetTranslation of the decorated instance at all to get all translations of a certain language. It would fire its own query against the database. This breaks the decorator pattern, because every functionality provided by the decorated instance is simply skipped. This becomes a real problem if there are other decorators involved. My understanding is that a Decorator should be additive. In this case however, the decorator is replacing the behavior of the decorated instance. I can't really think of a nice solution for this - how would you solve it? Everything is allowed, even a complete re-design of ITranslationService itself.

• Optimal sprite size for rotations

  - by Panda Pajama

  I am making a sprite based game, and I have a bunch of images that I get in a ridiculously large resolution and I scale them to the desired sprite size (for example 64x64 pixels) before converting them to a game resource, so when draw my sprite inside the game, I don't have to scale it. However, if I rotate this small sprite inside the game (engine agnostically), some destination pixels will get interpolated, and the sprite will look smudged. This is of course dependent on the rotation angle as well as the interpolation algorithm, but regardless, there is not enough data to correctly sample a specific destination pixel. So there are two solutions I can think of. The first is to use the original huge image, rotate it to the desired angles, and then downscale all the reaulting variations, and put them in an atlas, which has the advantage of being quite simple to implement, but naively consumes twice as much sprite space for each rotation (each rotation must be inscribed in a circle whose diameter is the diagonal of the original sprite's rectangle, whose area is twice of that original rectangle, supposing square sprites). It also has the disadvantage of only having a predefined set of rotations available, which may be okay or not depending on the game. So the other choice would be to store a larger image, and rotate and downscale while rendering, which leads to my question. What is the optimal size for this sprite? Optimal meaning that a larger image will have no effect in the resulting image. This is definitely dependent on the image size, the amount of desired rotations without data loss down to 1/256, which is the minimum representable color difference. I am looking for a theoretical general answer to this problem, because trying a bunch of sizes may be okay, but is far from optimal.

That issue could have been addressed by simply fixing the script and then regenerating the installation program, but a) it was judged to be less work to create a new release based on the current development code, and b) a new release does a better job of communicating the fact that the installation program for the previous release is broken...SEToolbox: SEToolbox 01.041.012 Release 1: Added voxel material textures to read in with mods.

This should be more transparent to users and ensure consistency in the number of ratings output by different computers. Separated the XLS and XLSX output formats in the save file drop-down box. This should be more transparent to users than having to add the appropriate extension.Magick.NET: Magick.NET 6.8.9.601: Magick.NET linked with ImageMagick 6.8.9.6 Breaking changes: - Changed arguments for the Map method of MagickImage. - QuantizeSettings uses Riemersma by default.Wallpapr: Wallpapr 1.7: Fixed the "Prohibited" message (Flickr upgraded their API to SSL-only).DbEntry.Net (Leafing Framework): DbEntry.Net 4.2: DbEntry.Net is a lightweight Object Relational Mapping (ORM) database access compnent for .Net 4.0+.

• Reusing Web Forms across BPM Roles

  - by Mona Rakibe

  Recently Varsha(another BPM Product Manager) approached me with a requirement where she wanted to reuse same Web Form for different task activity.We both knew this is easily achievable.The human task outcomes can differ to distinguish the submission based on roles.Her requirement was slightly more than this, she wanted to hide some data based on the logged in user. If you have worked on Web Form rules, dynamically showing and hiding data is common requirement and easily achievable using Form Rules. In this case the challenge was accessing BPM role inside the Web Form. Although, will be addressing this requirement in future release she wanted a immediate solution(Aha, after all customers are not the only one's who can not wait). Thankfully we managed to come-up with a solution and I hope this will be helpful to larger audience. Solution has 3 steps : Step 1: We added a hidden attribute in our form (Role). The purpose of this attribute is just to store the current logged in user's role and we pass the value during data association. Step 2 : In your data association step, pass the role value based on the Swimlane Step 3 : Now use this hidden attribute value in your Web Form rule for dynamic behavior Detailed steps and sample can be downloaded from Java.net.

• Mocking concrete class - Not recommended

  - by Mik378

  I've just read an excerpt of "Growing Object-Oriented Software" book which explains some reasons why mocking concrete class is not recommended. Here some sample code of a unit-test for the MusicCentre class: public class MusicCentreTest { @Test public void startsCdPlayerAtTimeRequested() { final MutableTime scheduledTime = new MutableTime(); CdPlayer player = new CdPlayer() { @Override public void scheduleToStartAt(Time startTime) { scheduledTime.set(startTime); } } MusicCentre centre = new MusicCentre(player); centre.startMediaAt(LATER); assertEquals(LATER, scheduledTime.get()); } } And his first explanation: The problem with this approach is that it leaves the relationship between the objects implicit. I hope we've made clear by now that the intention of Test-Driven Development with Mock Objects is to discover relationships between objects. If I subclass, there's nothing in the domain code to make such a relationship visible, just methods on an object. This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I can't figure out exactly what he means when he says: This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I understand that the service corresponds to MusicCentre's method called startMediaAt. What does he mean by "elsewhere"? The complete excerpt is here: http://www.mockobjects.com/2007/04/test-smell-mocking-concrete-classes.html

• Introducing the New Boot Framework in CE 7

  - by Kate Moss' Open Space

  CE 7 introduces a new boot loader framework, BLDR (platform\common\src\common\bldr\). Some people like its powerful and flexbility, others may feel its too complicate as a boot loader framework. Despite to the favor, it is already there; so let's take a look at its features. Unlike the previous BL framwork (CE7 still provides it in platform\common\src\common\boot\) is a monolithic library, the new framework has more architecture structure. It not only defines main body but also provides rich components, such as filesystem (BinFS/FAT), download transportations, display, logging and block devices: bios INT13, FAL, IDE, Flash ( and etc. Note that in the block device category, the FAL is for legacy FMD/FAL, Flash is for latest MSFlash. Some of you may have encountered MSFlash MDD/PDD compatible partition is hard to created in bootloader and now it provides a clean solution! (Since this is a big topic, I will introduce it in future post) Today, I am going to show you some basic helper components - Image Loading functions. When OS image stored in the block device, it can be a file format, says your NK.BIN in the FAT volume or a RAW format, says the image is programmed to a BINFS partition. For the first one you can use BootFileSystemReadBinFile (platform\common\src\common\bldr\fileSystem\utils\fileSystemReadBinFile.c) and use BootBlockLoadBinFsImage (platform\common\src\common\bldr\block\utils\loadBinFs.c) to load from a partition. Need a sample code? No problem, the BootLoaderLoadOs in platform\cepc\src\boot\bldr\loados.c just provide a perfect example.

• Get external metadata with streamripper using python script

  - by user72379

  Hi I like using streamripper to rip music from the web. I have a favorite radio station that doesn't have the metadata for the songs, so I have to screen scrape it from its website manually. I created this neat python script in the format that the docs suggest, and linked the address in the GUI for streamriper. But it still doesn't work, any one know how to make it work..? I know it used to work. It gives you a sample here: http://streamripper.sourceforge.net/history.php import http import time import re u = 'SEE IMAGE FOR THIS URL' s = http.Session(0, 0) s.add_headers(h, persistent=1) while 1: c = unicode(s.get(u)) pat = r'class="title"([^<]+)([^<]+)' m = re.search(pat, c) title = m.group(1) artist = m.group(2) print 'TITLE='+title+'\n'+'ARTIST='+artist+'\n.\n' time.sleep(30) [img]http://s11.postimage.org/sok928lsz/urlstream.png[/img] I put the address to the script here: [img]http://s17.postimage.org/4bhmhi4yn/streamripper.png[/img] I've tried putting it in the root of the streamripper application and doing this: lax.py I've even compiled it to a EXE, and tried linking to that.. nothing What am I doing wrong?

• Cocos2d v2.0 and OpenGL 2.0/1.0: where to start

  - by mm24

  I started developing my very first game 3 months ago using Cocos2d 2.0 for iPhone. I am now in the stage where I'd like to add some cool effects to the bullets and some special weapons (see my waveforms question here). I got a good answer in the cocos2d-iphone forum (see this one). Unfortunately I am a bit paralized now. I don't know if I will be overdoing by learning OpengGL 2.0 or if I should just stick ot the old 1.0. There is a good intro on various tutorial's written in Steffen Itterheims blog (see this post). I would like to add to my game: a blur effect to the bullets (here is a tutorial for OpenGL 1.0) a waveform (see above) some realistic water ripples (here is a nice sample code) So now, given that I don't want to overdo things but at the same time I want to achieve those effects, from where should I start? Should I discard the OpenGL 1.0 tutorials? OR should I use only OpenGL 1.0 code? How can I avoid confusion? I mean, it seems that the compiler recognizes both, but that there are some conflictual calls in some circumnstances, I am fairly sure this has some explanation, is there some reference to this somewhere?

• I am looking to create realistic car movement using vectors

  - by bobthemac

  I have goggled how to do this and found this http://www.helixsoft.nl/articles/circle/sincos.htm I have had a go at it but most of the functions that were showed didn't work I just got errors because they didn't exist. I have looked at the cos and sin functions but don't understand how to use them or how to get the car movement working correctly using vectors. I have no code because I am not sure what to do sorry. Any help is appreciated. EDIT: I have restrictions that I must use the TL engine for my game, I am not allowed to add any sort of physics engine. It must be programmed in c++. Here is a sample of what i got from trying to follow what was done in the link I provided. if(myEngine->KeyHeld(Key_W)) { length += carSpeedIncrement; } if(myEngine->KeyHeld(Key_S)) { length -= carSpeedIncrement; } if(myEngine->KeyHeld(Key_A)) { angle -= carSpeedIncrement; } if(myEngine->KeyHeld(Key_D)) { angle += carSpeedIncrement; } carVolocityX = cos(angle); carVolocityZ = cos(angle); car->MoveX(carVolocityX * frameTime); car->MoveZ(carVolocityZ * frameTime);

• Create indefinitely oscillating pendulum in Farseer Physics 3.3.1/Box2d

  - by GONeale

  I am new to Farseer Physics and using version 3.3.1. I am after some help and would even be happy to receive Box2d answers just to ensure I get a response as I should then be able to convert it! -- Thanks ...After a lot of tinkering around I have managed to produce a thin vertical rectangle shape on the screen and I wish this to swing back and forth pinned at the top up to an angle I set (90 degrees would be fine for this sample). When it is approaching the top I wish it to slow down, then fall back the way it just came, increase speed then obviously slow to a stop at the top again. Almost how a swinging pirate ship would work at a theme park. This is the code I have so far which swings the shape, but it is seeming to lose speed on each swing eventually grinding to a halt: float playerWidth = ConvertUnits.ToSimUnits(5), playerHeight = ConvertUnits.ToSimUnits(68); playerPosition = ConvertUnits.ToSimUnits(-350, 0); playerBody = BodyFactory.CreateRectangle(World, playerWidth, playerHeight, 2f, playerPosition); playerBody.BodyType = BodyType.Dynamic; // create player sprite based on player body _rectangleSprite = new Sprite(ScreenManager.Assets.TextureFromShape(playerBody.FixtureList[0].Shape, MaterialType.Player, Color.Orange, 1f)); // Create swinging joint var joint = JointFactory.CreateFixedRevoluteJoint(World, playerBody, ConvertUnits.ToSimUnits(0, -34), playerBody.Position); If somebody could also provide the command I would need to pause the shape on a mouse click or keyboard command at it's current angle and then continue when I let go of the mouse click that would be super fantastic! (I actually posted this on StackOverflow as well before I realised there was a dedicated game development forum) Cheers

• Recasting and Drawing in SDL

  - by user1078123

  I have some code that essentially draws a column on the screen of a wall in a raycasting-type 3d engine. I am trying to optimize it, as it takes about 10 milliseconds do draw a million pixels using this, and the vast majority of game time is spent in this loop. However, I don't quite understand what's occurring, particularly the recasting (I modified the "pixel manipulation" sample code from the SDL documentation). "canvas" is the surface I am drawing to, and "hello" is the surface containing the texture for the column. int c = (curcol)* canvas->format->BytesPerPixel; void *canvaspixels = canvas->pixels; Uint16 texpitch = hello->pitch; int lim = (drawheight +startdraw) * canvpitch +c + (int) canvaspixels; Uint8 *k = (Uint8 *)hello->pixels + (hit)* hello->format->BytesPerPixel; for (int j= (startdraw)*(canvpitch)+c + (int) canvaspixels; (j< lim); j+= canvpitch){ Uint8 *q = (Uint8 *) ((int(h))*(texpitch)+k); *(Uint32 *)j = *(Uint32 *)q; h += s; } We have void pointers (not sure how those are even represented), 8, 16, and 32 bit ints (h and s are floats), all being intermingled, and while it works, it is quite confusing.

• Moving 2d camera in the y direction

  - by Alex

  I'm developing a simple game for the iphone and am struggling to work out the best way for the camera to follow the main character. The following picture hightlights the three main components: There are 3 components to this: Circle - the main character Green line - terrain Black background The terrain is simply made from an array of points (approx 20 points per screen width). The terrain is moved in the x direction relative to the black background in order to keep the circle in its position shown. The distance to move the terrain is simply: movex = circle.position.x - terrain.position.x with a constant to fix the circle at some distance from the left of the screen. I am struggling to determine the best way to position the terrain in the y plane keep the focus in the character. I want to move the terrain in the y direction smoothly and not fix it to the position of the circle, so the circle can move in the y plane. If I take the same approach as the x positioning, the character is fixed at a point on the screen and the terrain moves. I could sample some terrain points either side of the character and produce an average, but in my implementation this was not smooth. I thought another approach might be to create a camera 'line' that is a smooth version of the terrain line and make the camerea follow this, but I'm not sure if this is the optimum solution. Any advice is much appreciated!

• Fix a jQuery/HTML5 dynamic content issue by upgrading jQuery

  - by Steve Albers

  The default NuGet template for MVC3 pushes down jQuery 1.5.1.  You can upgrade to a new version (1.7.1 is current when this is written) to avoid a problem with the creation of “unknown” HTML5 tags in IE6-8: Take this sample HTML page using HTML5Shiv to provide support for new HTML5 tags in IE6 – IE8.  The page has a number of <article> tags that are backwards compatible in Internet Explorer 6-8 thanks to the HTML5Shiv. After the article elements there is a jQuery 1.5.1 script tag, and a ready() event handler that appends a footer element with a copyright to each of the article tags.  This appears correctly in IE9, but in older IE browsers the unknown tag problem reappears for the dynamic <footer> elements, even though we have the HTML5Shiv at the top of the page.  The copyright text sits outside of the two separate footer tags. To solve the issue upgrade your jQuery files to an up-to-date version.  For instance in Visual Studio 2010: In the Solution Explorer right click on References and choose Manage NuGet Packages. In the Manage NuGet Packages window select the jQuery item on the middle of the page and click the “Upgrade” button. You may need to upgrade your script src references to point at the new version. Using the updated jQuery library the incorrect tags should disappear and styles should work properly:   You can find more information about the issue on the jQuery Bug Tracker site.
