Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
I had an idea for a wave project that I was going to build. I requested and received a dev and test account and played about with the UI. I managed to get the openfire extension installed on my server, the google appspot account setup, a particular non-repo version of eclipse and the GWT extension (on one version of Ubuntu). I built a crude robot (the logic) and a gadget (the UI), uploaded it and saw it working. If I bought a SSL cert I could have federated so that the robot code ran on my server (as my app would have needed to do).
I liked that it was an extension to XMPP. I liked a lot about the direction google took the project. Yes, the UI was flakey at the time (last year) and I had my doubts about how federation would scale. The thing I was waiting for was some server-side code for the web part of a federated server to be made available.
I put in quite a bit of effort to get that far and had faith in google's faith in the platform. I'm surprised wave has been pulled and I'm sure developers that put in more work than I will feel let down. It is not often that google cancels a product, especially such a large one that has had so much work thrown at it. I believe the idea was a good one, that it flowed from naturally XMPP and hope it flourishes in a FLOSS way in the future.
The pressure difference theory accounts for only a fraction of the generated lift. The majority comes from the the reaction from deflecting the air downwards.
Laminar flow causes the air to stick to the top of the wing and is redirected slightly downwards, the underside pushes yet more air downwards in a more obvious way. The vertical component of this is what generates most of the lift.
I also had BIOS malware back in '95. Went online with win95 and the machine lasted 4 days. That's actually what got me into Linux, and that's when my learning really started.
A big thank you to whoever did that to me!
