We have a winner. Daniel Langh was the first one to get a solution to me. Here is it is: And the source. A few others got solutions as well. Hope you had fun doing it. read moreMathworld Problem of the Week (free book!)

This week’s subject is Malfatti Cirlces: http://mathworld.wolfram.com/MalfattiCircles.html They look something like this: Basically, tangent circles, but each circle is also tangent to two sides of the given triangle. The challenge would be to take the file below: http://www.bit-101.com/blog/ read moreMay 07 2008
Here’s another one from MathWorld, the Butterfly Function. Non-interactive, but pretty. Source. read moreMay 07 2008
We have a winner! At 4:05 a.m., I received the following from Ryan Phelan, who will get a free copy of Foundation ActionScript Animation 3.0: Making Things Move! And the source. As you can see, a Soddy Circle is one of the two circles which are tangent to the other three… read moreMay 07 2008
If you are ever a bit bored and looking for some cool material for some Flash Math Experimentation (surely there are one or two of you out there besides myself who do stuff like this), check out Wolfram Mathworld. Start browsing til you find something interesting and try to do… read moreMay 03 2008
David Tudury is a guy who used to be on the Flash forums back in the day. I remember he did some crazy 3D stuff back before Papervision was even a dream. After a long hiatus, he is back with PseudoBiotic. Nice to see some old school Flash experimentation going… read moreApril 15 2008
Another one related to component creation, but a question this time... Does your syslogd sometimes go out of control? Whenever I save the Component Definition dialog, export a SWC, Convert to Compiled Clip, or Save the file I'm creating my components in, my CPU pretty much maxes out. Activity Monitor shows… read moreApril 15 2008
I wanted to mention that little badge up on the top right of the blog. The one that says, “get instant updates whenever I post.” This is the brainchild of Chuck Freedman, and you can find out more about it and get a badge for your own blog at http://www.relaymonkey.com/. But,… read moreAS3 graphics.drawCircle() glitch
April 12 2008
Not sure if I'd go so far as to call this a bug, but it's one of those little things that usually never bothers you, but every once in a while, comes up and bites you. Take the following code: PLAIN TEXT Actionscript: graphics.lineStyle(0); graphics.moveTo(100, 100); graphics.lineTo(200, 200); graphics.beginFill(0); graphics.drawCircle(300, 100,… read moreApril 11 2008
I’ve been using Jing for screen captures. It also has video capture capabilities. There are a few problems with it though. One is that the output is a SWF, so you can’t edit it or upload it to YouTube or whatever. The other is that if you publish to Screencast,… read moreApril 11 2008
I wanted to clarify a few details about the Verlet IK engine I posted some videos on earlier. First of all, it's not just the editor you see there. It is an engine comprised of several classes that I will be open sourcing as soon as it's ready. So you… read moreApril 11 2008
A little project that I have been working on this week. More to come… Actually, I’ve built this about three times in the last year. I’m getting pretty good at it. This one should see the light of day. Here’s another one, showing some more features. I should also mention,… read moreApril 10 2008
Well, for a couple of hours anyway. I’m actually doing a presentation to the Harvard University Flash Users Group, led by Philip Desenne, who is also a regular member of the Boston Flash Platform User Group. Anyway, I should probably have mentioned this some time before I’m about to walk out… read more
