SGI has filed for chapter 11 Not unexpected. Surprising it took so long to take some action… Back in the days when I could get my hands on a SGI machine they were a joy to program. IRIX is a great OS - it was one of the few that actually met the POSIX specs for threads. Great APIs. I wish they would just sell or give away IRIX for the PC x86 platform. Lots of people with fond memories of SGI workstations from the past would glady install IRIX in favor of Linux I think. 

What’s the different between this

Jacob Kaplan-Moss gave a talk on Django at Google for BayPIGgies.

By asymetrical subscribe/unsubscribe I mean a web service that has one way for subscribing and another for unsubscribing. Typically subscribing is easy - you input your credit card details on a web form and you’re done. If you can subscribe via a web page you should be able to unsubscribe via another web page. But a few online services make it very hard to unsubscribe - I think for obvious reasons. This only serves to annoy users even more - hence making it unlikely a user will ever re-subscribe. 

Now, if you have a field in a form that only accepts certain values don’t you think that it would be a good idea to tell the users of the form what those values are before they’ve filled them in? I am sick of the “invalid email” error after a form has been submitted. Why is so hard to indicate what valid values are beside the field? Or why can’t this be validated in JavaScript? It’s simply a lack of thought by the page designer/programmer.
