• Annotate source code with diagrams as comments

  - by Steven Lu

  I write a lot of (primarily c++ and javascript) code that touches upon computational geometry and graphics and those kinds of topics, so I have found that visual diagrams have been an indispensable part of the process of solving problems. I have determined just now that "oh, wouldn't it just be fantastic if I could somehow attach a hand-drawn diagram to a piece of code as a comment", and this would allow me to come back to something I worked on, days, weeks, months earlier and far more quickly re-grok my algorithms. As a visual learner, I feel like this has the potential to improve my productivity with almost every type of programming because simple diagrams can help with understanding and reasoning about any type of non-trivial data structure. Graphs for example. During graph theory class at university I had only ever been able to truly comprehend the graph relationships that I could actually draw diagrammatical representations of. So... No IDE to my knowledge lets you save a picture as a comment to code. My thinking was that I or someone else could come up with some reasonably easy-to-use tool that can convert an image into a base64 binary string which I can then insert into my code. If the conversion/insertion process can be streamlined enough it would allow a far better connection between the diagram and the actual code, so I no longer need to chronographically search through my notebooks. Even more awesome: plugins for the IDEs to automatically parse out and display the image. There is absolutely nothing difficult about this from a theoretical point of view. My guess is that it would take some extra time for me to actually figure out how to extend my favorite IDEs and maintain these plugins, so I'd be totally happy with a sort of code post-processor which would do the same parsing out and rendering of the images and show them side by side with the code, inside of a browser or something. Since I'm a javascript programmer by trade. What do people think? Would anyone pay for this? I would.

• If not gamedev, what do I do !

  - by brainydexter

  Hi, I am a game dev who was working in the game-industry and then..got laid off. Ever since then, life couldn't get less stressful! During this time, I have met so many other devs who have also been laid off irrespective of the number of years they have been in the game. Now, the problem really gets worse, since I am not a US citizen (yes, I am in US) , and am on an international visa here, I might have to soon pack my bags and go back to my native country. Going back is not bad at all, apart from the fact, that gamedev is still in a very nascent stage there. There just aren't many opportunities. So, employment is the key to maintain a valid visa status. After giving it a lot of thought, I am thinking of staying away from gamedev jobs for the time being, given its job unstablity. This brings me to my current problem. I can't think of a domain/place where I can use my game development skills. I know graphics/simulation/visualization is huge, but I can't think straight and am left clueless where to go from here. What are some of the domains/companies where I can use my skills ? I'd appreciate any insight on this (and I apologize if this is not the place to post this kind of a question).

• N64oid Brings N64 Emulation to Android Devices

  - by ETC

  Craving some Ocarina of Time adventures, Super Mario 64 antics, or some Star Fox 64 flying on your Android device? N64oid brings retro emulation of Nintendo’s popular N64 console to Android devices. N64oid is an N64 console emulator for Android devices. You’ll need a copy of the $5.99 emulator, ROMs (from the usual sources, unless you’ve got a ROM ripping setup in your basement and a stack of old cartridges), and a suitably speedy Android device. Older Android devices will find the playback choppy and subpar, but newer and speedier devices like the Nexus-One and Samsung Galaxy should have no problem handling the emulator. Like all emulators N64oid is a work in progress and emulating an entire closed-system console on a totally different set of hardware is never a perfect 1:1 emulation, but if you’re a die hard fan of classic N64 titles (check out this list of top ranked titles to inspire some nostalgia) N64oid is worth the price of a burger for sure.

• Resolution stuck after playing OpenGL game

• Compare Your Internet Cost and Speed to Global Averages [Infographic]

  - by ETC

  Internet pricing and speed varies wildly across the world. The US, for instance, currently ranks 15th in speed but enjoys reasonably priced internet access. How reasonably priced? If you’re a US citizen you likely have an average internet access speed of 4.8 mbps and you pay a little over $3 per mbps. If you’re in Sweden, however, you likely have an 18 mbps connection and you pay a scant 63 cents per mpbs. The real envy of the internet speed Olympics by far is Japan with a mighty 61 mbps at a mere 27 cents per mbps.

• kubuntu 12.10 will not boot on mac 2.93Ghz intel core 2 duo

  - by Jake Sweet

  I feel like I've tried it all and nothing is changing. I've tried booting from a liveUSB, a liveDVD, and I've checked the mod5 everything matches up. I've even tried different distro's same result on all of them. Just for reference: linuxmint 13kde and Fedora 17. I've also tried changing my liveUSB building software just in case. I've tried unetbootin and Linux USB builder. Both have same results, my opinion is that it is a hardware issue since I'm having near the same result with all of these variables. So now what is actually happening? I can boot up to a screen. I say A screen because some of the ways that dvd's and usb's boot differs. Now on liveusb I'm reaching a black screen with white text. Says booting: done, then below says loading ramdrive: done, then below that it says preparing to boot kernel this may take a while and buckle in or something to that effect. Then nothing. That's it computer freezes. I've waited up to 8 hrs and still nothing. Ok for the liveDVD Everything goes according to instructions per pdf files on every distro, until linux starts. I can only run in compatibility mode. When any other option is tried the computer seems to freeze/stall/be a pain in my butt... Ok well that seems to wrap it up. Also if I'm not explaining something well, I'm sorry I can try to clear anything up. I'm not the best at descriptions. I'm leaving with a tech specs of my mac: 2.93GHz Intel Core 2 Duo, 4 GB ram, NVIDIA GeForce GT 120 graphics, bought in late 09" it's the 24" model, let me know if anymore information will help. Also thanks in advance

• KDE not loading without nomode tag in grub and bad resolution [migrated]

  - by fcole90

  I recently installed Linux Mint 13 KDE but it's not working fine. At first I had to use failsafe mode to boot because normal boot takes to a textual login. If I use normal boot and text login I'm not able to run KDE nor with kdm start neither with startx. kdm says that's already running. Instead X is not able to run because can't connect Xserver to display. If I stop kdm and starx again doesn't change anything. Now I edited the grub to load in nomode. In that way KDE loads but resolution is wrong and xrandr doesn't help, because if I do this: cvt 1366 768 it changes it to 1368: # 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync I also installed bumblebee and nvidia drivers because of optimus technology..

• ParticleSystem in Slick2d (with MarteEngine)

  - by Bro Kevin D.

  First of all, sorry if this sounds very newbie-ish. I'm stuck at making a ParticleSystem I made using Pedigree to work in my game. It's basically an explosion that I want to display whenever an enemy dies. The ParticleSystem has two emitters, smoke and explosion I tried putting it in my Enemy (extends Entity) class Enemy extends Entity class @Override public void update(GameContainer gc, int delta) throws SlickException { super.update(gc, delta); /** bunch of codes */ explosionSystem.update(delta); } @Override public void render(GameContainer gc, Graphics gfx) throws SlickException { super.render(gc, gfx); if(isDestroyed) { explosionSystem.render(x,y); if(explosionSystem.getEmitter(1).completed()) { this.destroy(); } } } And it does not render. I'm not sure if this is the proper way of implementing it, as I've considered creating an Entity to serve as controller for all the Enemies. Right now, I'm just adding enemies every second. So how do I render the ParticleSystem when the enemy dies? If anyone can point me to the right direction. Thank you for your time.

• First Look - Oracle Data Mining

  - by kimberly.billings

  In his blog, JT on EDM, James Taylor shares his analysis of Oracle Data Mining, including its new GUI and Exadata integration. While Oracle Data Mining has been available for a while, it is now easier to access and try via the Amazon Cloud. Using the Oracle 11gR2 Data Mining Amazon Machine Image (AMI), you can launch an Oracle Data Mining-enabled instance directly through Amazon Web Services (AWS) and connect to it using the Oracle Data Miner graphical user interface. The new Oracle Data Mining GUI, which will be available to beta customers soon, provides more graphics, the ability to define, save and share analytical "work flows" to solve business problems, and provides more automation and simplicity. Taylor comments that, "the UI looks to have a nice look and feel including graphical model development flows, easy access to the data, nice little micro graphs when browsing data records and more." On using Oracle Data Mining with Exadata, Taylor writes, "Oracle says that the use of the ODM routines in the Exadata kernel is faster than running a native ODM model in the database by a factor of 2 and that this increases as more joins are used. This could mean that ODM outperforms even third party in-database analytics." Taylor concludes his blog with a positive overall review, stating that "ODM is a nice product for Oracle database customers and well worth looking into. The new UI will only make it more so." Read the blog. var gaJsHost = (("https:" == document.location.protocol) ?

• How to Clean Up and Fix Your Music Library with the MusicBrainz Database

  - by Erez Zukerman

  Over the years, some of us accumulate lots and lots of music files. Since these come from a variety of sources, they’re not always as neat as they could be. If your music library is in a bit of a jumble with tags missing, oddly named files and incomplete albums, read on to see how easy it is to make it neat once and for all. MusicBrainz is an online database that uses audio “fingerprints” to identify music tracks even when they’re incorrectly labelled. We’ll be using this database through a free client called Picard, available for Windows, Mac OS X and Linux. So first thing, head on over to Picard’s download page and get the installer. If you use Linux, you can install Picard using your package manager. Once you finish going through the installer, run Picard. Your firewall might pop up an alert telling you Picard is trying to access the Internet; you should agree to let Picard through. You will now see the main Picard interface.

• Insufficient permissions within Eclipse when installed via synaptic in Ubuntu 12.04

  - by Clayton

  I installed Eclipse via the Synaptic Package Manager on Ubuntu 12.04 Desktop (more details on footer). However, from within Eclipse, I lack sufficient permissions to perform upgrades on my package and add-ons. I'm a recovering Windows user, and while I have a couple of years Ubuntu experience, I am unfamiliar with the command-line and mainly interact through the packaged GUI. Specifically, I am trying to install the upgrade for Eclipse CVS Clientorg.eclipse.cvs.feature.group1.3.100.v20110520-0800-7B78FHl9VF7BD7KBM4GP9C I am tracking the varying installation advice on a similar question eclipse install: Gaurav Butola Basically, the most current upgrades are available directly from eclipse?... But at some point I remember reading that the latest version of eclipse had been designed for the previous LTS of Ubuntu - I don't know if that is still true. I have read about the vulnerabilities of Java 6, and so I have gone with Open Java 7 openjdk-amd64 (if that has any relevance to which Eclipse package and installation method I choose). But I'm not crazy about the idea of creating a gksudo link in the sidebar launcher. I don't know enough about chown to use it - if that's even appropriate (I don't want stray java escaping from Eclipse and connecting to SkyNet). Another possible solution that I foresee is modifying my user's group memberships/privileges on the file system as a whole. The only other information that I think might be relevant is that I notice that Synaptic installed all of the files into /usr/ instead of /opt/ like I have seen recommended. So should I be changing ownership, reinstalling using a non-Synaptic method, or what? Any advice is greatly appreciated.

• XNA Masking Mayhem

  - by TropicalFlesh

  I'd like to start by mentioning that I'm just an amateur programmer of the past 2 years with no formal training and know very little about maximizing the potential of graphics hardware. I can write shaders and manipulate a multi-layered drawing environment, but I've basically stuck to minimalist pixel shaders. I'm working on putting dynamic point light shadows in my 2d sidescroller, and have had it working to a reasonable degree. Just chucking it in without working on serious optimizations outside of basic culling, I can get 50 lights or so onscreen at once and still hover around 100 fps. The only issue is that I'm on a very high end machine and would like to target the game at as many platforms I can, low and high end. The way I'm doing shadows involves a lot of masking before I can finally draw the light to my light layer. Basically, my technique to achieveing such shadows is as follows. See pics in this album http://imgur.com/a/m2fWw#0 The dark gray represents the background tiles, the light gray represents the foreground tiles, and the yellow represents the shadow-emitting foreground tile. I'll draw the light using a radial gradient and a color of choice I'll then exclude light from the mask by drawing some geometry extending through the tile from my point light. I actually don't mask the light yet at this point, but I'm just illustrating the technique in this image Finally, I'll re-include the foreground layer in my mask, as I only want shadows to collect on the background layer and finally multiply the light with it's mask to the light layer My question is simple - How can I go about reducing the amount of render target switches I need to do to achieve the following: a. Draw mask to exclude shadows from the foreground to it's own target once per frame b. For each light that emits shadows, -Begin light mask as full white -Render shadow geometry as transparent with an opaque blendmode to eliminate shadowed areas from the mask -Render foreground mask back over the light mask to reintroduce light to the foreground c. Multiply light texture with it's individual mask to the main light layer.

• What are Information Centers?

  - by user12244613

  Information Centers are similar to product pages in the Oracle Sun System Handbook Many customers like the Oracle Sun System Handbook concept of a home page with all the product attributes, troubleshooting etc. access from a single home page.

• How to improve batching performance

  - by user4241

  Hello, I am developing a sprite based 2D game for mobile platform(s) and I'm using OpenGL (well, actually Irrlicht) to render graphics. First I implemented sprite rendering in a simple way: every game object is rendered as a quad with its own GPU draw call, meaning that if I had 200 game objects, I made 200 draw calls per frame. Of course this was a bad choice and my game was completely CPU bound because there is a little CPU overhead assosiacted in every GPU draw call. GPU stayed idle most of the time. Now, I thought I could improve performance by collecting objects into large batches and rendering these batches with only a few draw calls. I implemented batching (so that every game object sharing the same texture is rendered in same batch) and thought that my problems are gone... only to find out that my frame rate was even lower than before. Why? Well, I have 200 (or more) game objects, and they are updated 60 times per second. Every frame I have to recalculate new position (translation and rotation) for vertices in CPU (GPU on mobile platforms does not support instancing so I can't do it there), and doing this calculation 48000 per second (200*60*4 since every sprite has 4 vertices) simply seems to be too slow. What I could do to improve performance? All game objects are moving/rotating (almost) every frame so I really have to recalculate vertex positions. Only optimization that I could think of is a look-up table for rotations so that I wouldn't have to calculate them. Would point sprites help? Any nasty hacks? Anything else? Thanks.

• Run a startup script with lightdm

  - by cheshirekow

  I have a tablet PC and the graphics driver doesn't support xrandr, so in order to rotate the screen I run a script which changes the Xorg.conf file and then restarts lightdm. I also have a script which uses xsetwacom and xinput to change the rotation of the input devices so that the match the new orientation. I've learned how to get the script to run when I login, but I'd like it to run before I login, so that I don't have to enable auto-login with lightdm. I do need it to run though, or the input (touch and pen) is rotated with respect to the screen, so that when I touch the screen the input is in a completely different area, making it really difficult to use the onscreen keyboard. I've looked at other questions on this site. I've tried putting my script in /etc/Xsession.d but that didn't seem to work. I also tried putting it in /etc/rc.local but I think that is the wrong place, nothing seems to happen. I've also tried googling for lightm script hooks, and various other google terms. Any suggestions? Edit 1: After doing some research, it seems to me that it might not be that I want to run a script with lightdm, but rather with the lighdm greeter (in this case, I think the unity-greeter?). Are there any script-hooks for the unity-greeter?

• Project Corndog: Viva el caliente perro!

  - by Matt Christian

  During one of my last semesters in college we were required to take a class call Computer Graphics which tried (quite unsuccessfully) to teach us a combination of mathematics, OpenGL, and 3D rendering techniques.  The class itself was horrible, but one little gem of an idea came out of it.  See, the final project in the class was to team up and create some kind of demo or game using techniques we learned in class.  My friend Paul and I teamed up and developed a top down shooter that, given the stringent timeline, was much less of a game and much more of 3D objects floating around a screen. The idea itself however I found clever and unique and decided it was time to spend some time developing a proper version of our idea.  Project Corndog as it is tentatively named, pits you as a freshly fried corndog who broke free from the shackles of fair food slavery in a quest to escape the state fair you were born in.  Obviously it's quite a serious game with undertones of racial prejudice, immoral practices, and cheap food sold at high prices. The game itself is a top down shooter in the style of 1942 (NES).  As a delicious corndog you will have to fight through numerous enemies including hungry babies, carnies, and the corndog serial-killer himself the corndog eating champion!  Other more engaging and frighteningly realistic enemies await as the only thing between you and freedom. Project Corndog is being developed in Visual Studio 2008 with XNA Game Studio 3.1.  It is currently being hosted on Google code and will be made available as an open source engine in the coming months.

• Stencyl or flash limitation?

  - by FlightOfGrey

  I have found that Stencyl doesn't seem to be very good at handling very many actors in a game. I had been trying to implement some basic AI at the moment all the behaviours were: wander (pick a random point and move directly to it) and wrap around screen (if it goes off the top of the screen it appears at the bottom). Even with these simple behaviours and calculations the frame rate dropped dramatically when there were more then 50 actors on screen: 10 actors: 60fps 50 actors: 30-50fps 75 actors: ~30fps 100 actors: 15-20fps 200 actors: 8-10fps I had planned on having a maximum of around 200 actors but I see that's no longer an option and implementing a more complicated AI system with flocking behaviour, looking at creating a game in a similar vein to flOw. I understand that a game is perfectly playable at 30fps but this is a super simple test with ultra simple graphics, no animations and no sounds is child's play in terms of calculations to be made. Is this a limitation with Stencyl or is it flash? Should I simply scale the scope of the game down or is there a better game engine that exports to .swf that I should look into?

• Rotating a view of a chunked 2d tilemap

  - by Danie Clawson

  I'm working on a top-down (oblique) tile-based engine. I would like for the tiles to have a definable height in the world, with Characters being occluded by them, etc. This has led to a desire to be able to "rotate" the view of the world, even though I'm using all hand-drawn graphics and blitting. Therefor, I need to rotate the actual world itself, or change how the Camera traverses these arrays. How can, or should, I create individual rotations of 90 degrees, when I have multi-dimensional arrays? Is it faster to actually rotate the array, to access it differently, or to create pre-computed accessor(?) arrays, something like how my chunks work? How can I rotate an individual chunk, or set of chunks? Currently I establish my tile grid like this (tile height not included): function Surface(WIDTH, HEIGHT) { WIDTH = Math.max(WIDTH-(WIDTH%TPC), TPC); HEIGHT = Math.max(HEIGHT-(HEIGHT%TPC), TPC); this.tiles = []; this.chunks = []; //Establish tiles for(var x = 0; x < WIDTH; x++) { var col = [], ch_x = Math.floor(x/TPC); if(!this.chunks[ch_x]) this.chunks.push([]); for(var y = 0; y < HEIGHT; y++) { var tile = new Tile(x, y), ch_y = Math.floor(y/TPC); if(!this.chunks[ch_x][ch_y]) this.chunks[ch_x].push([]); this.chunks[ch_x][ch_y].push(tile); col.push(tile); } this.tiles.push(col); } }; Even some basic advice on my data struct would be much appreciated.

• Firefox 12's hardware acceleration on Ubuntu 12.04 LTS

  - by user64943

  After I have installed Ubuntu 12.04 LTS (32 bits), Firefox 12 works fine but without hardware acceleration. Needless to say I have the latest nVidia's proprietary drivers installed and my Firefox Preferences, on "Advanced" tab, "Browsing" section, have the option "Use hardware acceleration when available" checked. I have tried the following things before asking this question: Creating a boolean key "webgl.force-enabled" and set it to true on Firefox's page about:config; Starting a new profile like commented on thread Mozilla Firefox 12 is very slow on Ubuntu 12.04 LTS; I have updated my nVidia driver to version 295.53. And none of this have worked. As you can see below in my Firefox's page about:support report, "Graphics" section shows no "GPU Accelerated Windows": Adapter Description NVIDIA Corporation -- GeForce GTX 460/PCIe/SSE2 Vendor ID NVIDIA Corporation Device ID GeForce GTX 460/PCIe/SSE2 Driver Version 4.2.0 NVIDIA 295.53 WebGL Renderer NVIDIA Corporation -- GeForce GTX 460/PCIe/SSE2 -- 4.2.0 NVIDIA 295.53 GPU Accelerated Windows 0 AzureBackend skia I use the following site to test hardware acceleration: http://ie.microsoft.com/testdrive/Performance/FishBowl/ On Windows 7 I get 60 fps even with 1,750 fishes on browser's Full Screen Mode (1680x1050x32bit-color). On Ubuntu 12.04 LTS, same nVidia drivers (as shown in report), won't go faster than 15 fps with only 1,000 fishes. Can anybody help me? Best Regards,
