ImageBEich.jpg My one-hundred-and-thirtieth podcast is up. I had the pleasure of talking to Brendan Eich about JavaScript this week. Brendan created JavaScript lo these many years ago, and lately his team has been working to make JavaScript even faster with TraceMonkey, their next step in their JavaScript engine. It's an exciting time for JavaScript as it approaches "C" speeds. I chat with Brendan in this episode about where he thinks JavaScript is headed. What does the rise of JavaScript mean to Flash, Silverlight and RIAs in general? We also talk about how TraceMonkey works and how much faster it can get.

Brendan is responsible for architecture and the technical direction of Mozilla. He is charged with authorizing module owners, owning architectural issues of the source base and writing the roadmapthat outlines the direction of the Mozilla project.

Brendan created JavaScript, did the work through Navigator 4.0, and helped carry it through international standardization. Before Netscape, he wrote operating system and network code for SGI; and at MicroUnity, wrote micro-kernel and DSP code, and did the first MIPS R4K port of gcc, the GNU C compiler.

One other change, this week a large number of the questions of Brendan came directly from you, the listener, via Twitter! This is a new thing I'm trying and I really feel it made for a better show and I thank you for it! I'm on Twitter at and you can read more about Twitter in my post on Twitter: The Uselessfulness of Micro-blogging if you want to jump in and "follow me." I encourage you to find a Twitter Client that works for you and give it a try.

Did you measure foreheads?

Ouch. That a "future me" comment? ;)
September 22, 2008 12:15
Future me*? Dunno. Am I missing a cultural reference? Or just generally ignorant?

I'm just genuinely curious. Seems like a close race. I'd say Scott's for height and Brendan's for area. But I can't know for sure until you measure up.

Anyways, time to download the episode!

Also, allow me to state that it is morning here. In case the word "forehead" has a blue interpretation, that part of the brain is still booting. (Height, area? Oh my.)

How about adding a Zune podcast subscription button next to that iTunes button on

I know, it's not that hard to copy and paste an rss link but the other 4% of us would feel special topped with a little integration sugar.

Wish there was better audio on this, it's hard to listen to Mr. Eich for long without getting annoyed from the reverb.

What a bunch of nonsense.

First of all JavaScript is so damn slow in interaction with DOM, it is not JS speed that should be the focus.

As for being same speed, yeah right.. 70x rule still applies, on anything moderately complex. The rule is:

Hi Scott,

When are you posting a message about podcast #34 (stackoverflow)? I have some pretty straight shooting comments for you on that one, but I don't want to leave them out of context :-)
