Sinatra + Kara == qwerty animals

Saturday, February 20th, 2010

Yesterday I released a small web app; it was my first using the Sinatra microframework for Ruby: http://qwerty.robertcarlsen.net

sinatra

The app arranges illustrations of animals wearing lettered t-shirts to create user-supplied messages. Kara Schlindwein created the illustrations as part of her project for the 6th Annual Fun-a-Day project in Philadelphia, and I wrote the first draft of the app while sitting in a chair at the show a couple of weeks ago, still nursing my broken ankle.

OCR on iPhone demo

Sunday, December 6th, 2009

Update: Source code for demo project released.

TessIcon

i finally got around to building a proof of concept implementation of tesseract-ocr for the iPhone. months ago, i documented the steps which helped to get the library cross-compiled for the iPhone’s ARM processor, and how to build a fat library for use with the simulator as well. several folks have helped immensely in noting how to actually run the engine in obj-c++. thanks to everyone who has commented so far.

anyway, below is a short video of the POC in action. the basic workflow is: select image from photo library or camera, crop tightly on the box of text you’d like to convert, wait while it processes, select / copy or email text. (more…)

coda

Friday, June 19th, 2009

i recently switched to Coda for web development. now, i don’t do much web dev any longer…mostly for myself (as evidenced my this latest overhaul of robertcarlsen.net – which amounts to theme hacking, really). i never had a problem with tabbing through several programs to get the job done, but i like Panic’s style.

the interface is clean and with keyboard shortcuts for each of the view modes. i do so wish for more info in the files panel….i’m used to comparing modification times and the sync features of full-fledged FTP clients.

anyway, it’s good software – and i’ve come to really appreciate good software lately after writing a lot of bad software myself.

[my] summer of code

Friday, May 22nd, 2009

iconIn preparation for several iPhone application development gigs which have lined up for the summer I’m getting back into my previous projects. Specifically, I’m going to get Follower and Pinwheel ready for release and am looking to push them out to the AppStore in the next month or so.

Also, as an exercise to get working with a web API I’m building an iPhone native client for SHIFD, called Slide. Right now it’s overly simplistic, but I much prefer the native app to the mobile web app. I’m not sure if I’m going to keep it as a learning project or also invest the time and resources to make it another released application.

All this is in service to building out cloudreader.me, the online version of the CloudReader generative text animation project. I’d like to make that something available sometime.

openFrameworks + iPhone libs

Wednesday, March 25th, 2009

of_iphoneI’ve had a few days to test the libraries I cobbled together for using openFrameworks with iPhone and also received positive reports from some folks who tried out the Makefiles I provided to them, so here they are for anyone who’s willing to try them out. -please make these instructions better if you see fit- (more…)

iPhone pinwheel: 4in4 day two

Tuesday, January 13th, 2009

the iphone is missing one of my most beloved relics of os x…the pinwheel, aka beachball of doom/death. i wanted to experiment with using the core graphics framework to draw to the screen and create animation and this was an interesting experience.

the animation is too slow currently…i feel that i’m doing things in a really inefficient way at the moment. i had also tried using UIImageViews and animating them, but i couldn’t figure out a way to get the spinning layer to composite using the overlay blend mode…which you can easily do with core graphics contexts.

i’ll try again later, but i really need to get away from the computer and onto my bike to train (which is a matter of about five feet now that it’s dark and icy out). i’ll post a video if i can get the animation on the phone to happen more quickly.

pinwheel

my first iphone app :)

Monday, January 12th, 2009

(i was going for a fisher-price approach with the title…)

regardless, i’ve finally gotten around to iPhone development. my developer account was approved last week, and apple happily took my $99 in exchange for slightly greater access to their website and an application code signing certificate. in preparation, i’ve been reading the requisite docs on objective-c, cocoa and iphone application programming. also, working on golden cheetah got me comfortable (sort of) coding in xcode.
