tripwire posted:Well, I still haven't found the bug, and I'm not so sure it's working. That picture is from many thousands of generations into the simulation where it should be converging to look like the source picture but the fitness seems to stay the same at roughly 50% similar to the source, forever. This is what you'd expect to happen if there was zero evolutionary pressure, or if there was no way at all for the drawings to pass on fit genes to future drawings (or put another way, it seems like either the drawing or some aspect of the evaluation of the drawing is failing completely). These things are a lot of fun to work on! I tried one back in April, though the only output I was really happy with was the firefox logo. http://digibob.co.uk/images/firefox/ I'm sure I had a gif of it kicking around, but I can't find it now.

 Click here for the full 825x1100 image. This is a GPS receiver my friend put together. The thing spits out NMEA messages, which are all mostly loving terrible (not guaranteed to arrive in order or well formed or at all, also just mostly a lovely spec). I wrote a python app to handle the incoming data from it, clean things up, and spit it back out. Also it scans for wireless networks, spits out name/mac/strength/gpslocation and some other stuff, as well as recording it in an SQLite database for later use.  The viewer opens the scanner as a subprocess and (tries) to make everything pretty fun to watch. It seems to work pretty well most of the time, but occasionally has a hard time updating, redrawing, and saving snapshots all at once. Hopefully I will be able to fix that all soon. :| http://atinybird.com/projects/witographer/bathursttoalbany.html I wrote a lot of this while we were driving from Bathurst, New Brunswick to Albany, New York, and managed to record a bunch of stuff on the way. http://atinybird.com/nest/panchos.avi Driving to a restaurant, the video kind of flips out because of some bad screenshots. Yay PyGTK <3

A while ago I half finished my python based cuda/opengl version of that steepest descent triangle picture evolver. Its actually pretty interesting to watch interactively. even though it suffers from the same terrible long term performance with such a dumb algorithm, no matter how much speed you throw at it rendering wise. Theres probably many ways it could be sped up GPU wise as I'm sure my attempt at cuda and opengl interop is very slow, but I'm I think it would be interesting to start fooling around with other reinforcement learning strategies and see how they handle the same general idea, or other approaches for image generation altogether.

Working on embedded stuff for a few years has really given me a bit more of a bottom-up understanding of simple micros. So, for a fun experiment I started writing an emulator for the first machine I ever owned, an Acorn Electron. Still no screen driver written for it yet, but I hooked a debug output to intercept its calls to the ROM routine that prints a character, and today it did this.  Pointless milestone, maybe, on a pointless task (the machine's already been perfectly emulated) but to have recreated my first computer in software makes me smile

Demoscene (http://en.wikipedia.com/wiki/Demoscene) production I designed and mostly coded: http://www.youtube.com/watch?v=0DCurP2a-FU OpenGL + GLU + GLEW for graphics and libSDL for windowing / timing code. Easily portable to pretty much any OS that can compile those libs and support shaders. The music uses a software synth called 4Klang by Alcatraz, and the visuals are mostly based on Lindenmayer system (L-system) fractals which are generated realtime and visualized in various ways.

 Click here for the full 1680x1050 image. I finally installed two (out of four total) Tesla cards in a new i7-based machine I built this weekend, and got them up and running earlier today. I'm currently trying to troubleshoot why I'm dying in CUDA kernel startup on the Teslas when running an n-body benchmark. It'll probably be another three weeks or so until I build the second GPGPU box (slated to be Linux).

Fixed a bunch of retarded bugs in my global illumination toy. The result was an extreme improvement in lighting quality. I think I got them all out because it actually looks really good now. 12" sample size + 1 bounce (a.k.a. lowest quality):  Click here for the full 640x400 image. Diffuse light only:  Click here for the full 640x400 image. (Yes I know there's a bright spot on one of the pillars. I know what causes it, I'm still working on fixing it.) In other news, one of the test maps won't even run without my computer BSODing due to an infinite loop in ATI's lovely video drivers.

Dataflow graph editor and library a la vvvv. This image is hiding a lot of complexity; the code's already over 200kb, and pretty much everything about it is used to produce this specific image. However, in general use it's much more lightweight and speedy than other graph editors, as it's intended to be embedded rather than used as a distinct program (that exists, but the program's about two lines of code). You could use it to load images, for example, or do more complex processing. Stuff layers in - if you don't use the editor, then components don't have any editing information attached to them. It also caches data to keep from loading plugins until they're actually necessary. Connections autoroute, show what they carry, and the connections animate in their direction of travel. Hovering over a connection or pin shows what information's on it, etc. Usability's an important part in short. It's focused on utilising plugins designed for other programs rather than having plugins directly built for it. The flip side is that I want to write plugins for these programs that plug into my code. This could be used to load images in Photoshop using an Irfanview plugin or do more complex things leveraging graphs.

I'm working on the successor to PixPlz1, originally written on Google App Engine. It's now written in Django using PostGreSQL. The most requested features from PixPlz1 were NWS images, ways to filter out certain types of photos (mainly "asian"), multi-file upload, and animated gif support so I added all of those. I would love to get some feedback on what you think of the design and the UI. I would also love to hear ideas for features or how this could otherwise be improved. http://pix-plz.com/  Click here for the full 1162x983 image.  Click here for the full 1162x983 image.

I've been working on a new game for the iPhone for the last month or so. I started programming it with Cocos2d. It was a little rough going at first, the docs seem pretty limited. I eventually got the hang of it, although I had to go back a few times and correct things. The game is like the flash game Totem Destroyer. I'm planning on doing a few things differently, namely a different theme. A fellow goon is doing the artwork. I'm having a hard time coming up with a name though... Here are a few W.I.P. shots:

A Processing game I was working on between college and getting a real job. Goal was to finish it and have something to show to game developers I was applying to. Didn't really have a design other than "I really liked the game Every Extend plus any game with chain reaction explosions are cool". As I worked on it I started to get gameplay ideas. Sadly they were never implemented because I stopped working on it once I got a job (didn't wind up working in the gaming industry either). Here are some screenshots: (Click for big)        You are the green square, blue triangles are enemies. Over time more enemy groups spawn. Premise is to dodge guys until you can't last any longer or find the ideal time to detonate and cause a huge chain reaction. Project was stopped before I made detonation actually kill you (which is why player is always on screen). It actually runs playable because Processing is using OpenGL to draw everything. All of the objects are drawn shapes (as opposed to sprites). I'm amazed it runs at all considering every shape is redrawn every frame. Despite the crude looking style, it looks pretty good in motion - explosions that expand quickly at the beginning and slower at the end of their lifespan (exponential ease out I guess, whichever one goes fast to slow), shifting hues based on chain reaction count, cheap frame blur. I've had a decent amount of fun just loving around with it too, I think it would make a fun little game. I REALLY want to try and finish this. I've been looking through the code a bit lately, not a whole lot to it - shouldn't be too hard to pick up and work on more. Dr. Glasscock fucked around with this message at 03:04 on Oct 1, 2009 |

LOLLERZ posted:I'm glad you noticed and gave me some specific stuff to fix. More details:  Click here for the full 868x280 image. The Flash warning implies I have the wrong version installed. Having "Step 2" on the far right and immediately usable is a bit confusing, it should be hidden or below "Step 1". Once I have browsed for some files it's not obvious that I have completed "Step 1", and the list of files is neither marked as a list of files or clearly separated in the layout.  Click here for the full 1037x298 image. The "upload files" should be a button if it's an action rather than a link to somewhere else, similar with "browse". After clicking on "upload files" the progress is shown on the left not the right hand side. Adding tags appears to be a "Step 3" but not indicated as such. There is no description what to do, that spaces separate tags, or by default nothing is selected - the last file group should be selected.  Click here for the full 1115x399 image. Adding a tag to an image deselects the image, a bit odd. You can add duplicate tags to an image. After adding many tags they are not displayed correctly, some being hidden, and it can be difficult to delete some as the boxes jump about.  After adding tags it's not apparent that I have completed the upload process or what I should be doing next. (edit) Holy cow, you realize that registering doesn't request or send any password? I have to re-use the registration link to sign in on a different machine. MrMoo fucked around with this message at 07:11 on Oct 1, 2009 |

So I've decided to try my hand at affiliate marketing. I created a site that lists upcoming auctions on eBay where the price is a lot lower than retail: https://www.glensdeals.com Unfortunately, a lot of the stuff selling cheap is crap that no one wants and I was debating changing my methodology to only show popular higher priced items. For example, instead of listing old versions of MS Office or used clothes that are selling for 20% of retail price I would show iPods and Xboxes that were 70% of retail. Also I was debating having separate websites that just focus on one category instead of showing everything on one page. I'd love to know what anyone thinks of the site or if anyone else has any experience with affiliate marketing.

Nice! I wanted to make animations and I didn't have many ideas and then got bored and moved on. realtime ideas: Frame recording - needs too much disk space on the fly MPEG encoding - could work? Maybe? I know this is how electric sheep works. - instead of normal MPEG, encode unfiltered histogram (faster/smaller?) Upsample/filter - couldn't find a filter with acceptable quality. Motivation on this was that the frames converge pretty quickly if they're small; for example, 640x480 might be ok to do in realtime. However, I couldn't produce an image that I could uspample in photoshop or other offline tools with acceptable iq so I figured the chances of doing it realtime were nil. And 640x480 is just too small for me.
