How To Host Every Language in Every Language

Last week, Scott Petersen from Adobe gave a talk at Mozilla on a toolchain he’s been creating—soon to be open-sourced—that allows C code to be targeted to the Tamarin virtual machine. Aside from being a really interesting piece of technology, I thought its implications for the web were pretty impressive.
The next steps Scott took are the most interesting, because he starts using this to build stock Python and Ruby runtimes that are hosted on Tamarin. This is a fascinating solution to one of our biggest itches: more languages on more platforms.

Imagining the sheer number of languages (most) this opens up to running on any Tamarin run-time (Flash and Firefox 4) is mind boggling. Go on, let your mind be boggled. Combine this with the basic idea being targetted to other platforms and you've got a lot of possibilities. Target other bytecode, like Java or .Net, and you open up more possible cross-builds than you can count. Platforms begin to fade on the borders.

At the same time, Mozilla is already busy learning to convert DLR bytecode to Tamarin bytecode, so I guess Java is the only bytecode left anyone (maybe) cares enough about getting to run on it. Down the road, could this mean Flash (and Firefox 4) will be the only platform supporting, essentially, any and all languages and libraries, in some form or another? Impressive.

Not only would Tamarin support Python, but potentially all major implementation of the language. Choices are great.

Of course, the same will be done for every platform, and once again the pattern repeats itself. Vendors will fight over control of the platform, just to be made irrelevent by one layer above them.

On Pruning Your Passions [MOVED]

We live in a hobby-rich world. There is no shortage of pastimes to grow a passion for. There is a shortage of one thing: time to indulge those passions. If you're someone who pours your heart into that one thing that makes your life worthwhile, that's a great deal. But, what if you've got no shortage of interests that draw your attention and you realize you will never have the time for all of them?

If I look at all the things I'd love to do with my life as a rose bush I'm tending, I realize that careful pruning is essential for the best outcome. This is a hard lesson to learn, because it can mean cutting beautiful flowers and watching the petals fall to the ground to wither. It has to be done.

I have a full time job that takes a lot of my mental energy. I have a wife and a son and family time is very important in my house. I try to read more, and I want to keep up with new developments in my career, and I'm trying to make time for simple, intentional relaxing t…

The Insidiousness of The Slow Solution

In software development, slow solutions can be worse than no progress at all. I'll even say its usually worse and if you find yourself making slow progress on a problem, consider stopping while you're a head.

Its easy to see why fast progress is better: either you solve the problem or you prove a proposed solution wrong and find a better one. Even a total standstill in pushing forward on a task or a bug or a request can force you to seek out new information or a second opinion.

Slow solutions, on the other hand, is kind of sneaky. Its insidious. Slow solution is related the Sunk Cost Fallacy, but maybe worse. Slow solutions have you constantly dripping more of your time, energy, and hope into a path that's still unproven, constantly digging a hole. Slow solutions are deceptive, because they still do offer real progress. It is hard to justify abandoning it or trying another route, because it is "working", technically.

We tend to romanticize the late night hacking…

Finding "One Game A Month"

I was really excited about the One Game A Month challenge as soon as I heard about it.
For about two years I've struggled in fits and starts to make my way into game development. This hasn't been productive in any of the ways I hoped when I started. Its really difficult to be fairly experienced as a developer, which I believe I am in my day job as a web developer, while struggling really hard at an area in which your experience just doesn't exist.
Its like being a pilot who doesn't know how to drive.

But this challenge provided a new breath to this little hobby of mine. It gave me a scaffolding to experiment, to learn, to reflect on finished projects. I had spent far too much time on game projects that stretched on far past their exciting phases, bogged down by bad decisions and regret.
And it has worked.
I have a lot to learn. I have a lot of experience to gain through trial and error and mistake and discovery. I have a lot of fun to be had making more small games t…
