DISQUS

I like it! Some kind of collaborative editing would be great, on par with Google Docs without all the extra weight. What happens if two people edit it now?

James Paul Gee dedicates the last chapter of "What Video Games Have to Teach Us about Learning and Literacy" to the "network." He argues the real measure of a person's abilities has to include all their network resources.

If I can't solve a problem, but my friends on Twitter can, then I really can solve it.

It goes even farther, to any networked resource. My knowledge "includes" everything on PHP.net, the MozDev network, and MSDN, because I know where to find them and how to use them.

You make a good point about Twitter and give me things to think about for my own application design. I've never handled more than 80k requests a day. I'd love to deal with this level of traffic--wouldn't we all--and work on Twitter-sized problems.

What's the best way to represent freelance work? I've been in one position for a while but have done some freelance work in my spare time. How do I get that on there?

I try to only follow people who are both interesting and at a similar pace. I tried following the NY Times for a while but there was so much noise.

If you read certain blogs, try following their authors. If you know friends with accounts, try following them, but don't be afraid to stop following someone who posts too much or too little.

And try using one of the 3rd Party apps, like, Twhirl, TwitterFox, or Twitterific. They can make it seem much less intense.

I think part of the brilliance of Twitter has been opening "Twitter-as-a-service," along with "Twitter-as-a-site."

A ubiquitous site on college campuses is the receptionist with Facebook open. The downside to sites like Facebook and MySpace is that they are "sites." They command the whole browser window. (And frankly, they make it painfully obvious that you're not working.)

Twitter is a service. Occasionally I use the site, but it's much less obtrusive to leave Twhirl or Twitterific running and go about my day.

I gotta use my math degree for something. A 50% speed increase for PHP would reverse the results of the experiment.

Using "!empty($a)" is 50% faster than "count($a) >0", according to my test (almost the same code, Xeon 2.4 GHz, 1GB). I did a 10-sample experiment and at alpha = 0.01 the t value came out to 150.

If you want to see the experiment: http://jamessocol.com/projects/count_vs_empty.php

Did you replace Hongli's "while (count($a)>0" with the correct "while (!empty($a)"?

Unfortunately, as long as the people who are legislating this are the same who claim "anything that can be a weapon, is a weapon," I doubt they'll understand that restricting the tools will not restrict the behavior.

I'm impressed--though maybe I shouldn't be--that Amazon could muscle the record companies into DRM-free music in a big way. It's nice to see them finally start relenting on that. We've been sorely lacking a good music store that works with both iTunes and Media Player-compatibles.
