RIA Presentations – Time and Room
On 23, Mrz 2011 | inRIA lecture | vonJohannes Hoppe
This Friday, the 25th of March (2011-03-25), I will be happy to see your presentations.
Leets meet at 10 o’clock AM in the foyer; too search for a suitable room!
I like presentations that are well prepared and where all team members are presenting. There is no fixed format ore time box!
It’s up to you how you want to convince me that you’ve created an amazing project. But please keep in mind that too long or too boring presentations won’t be very convincing! ;-)
Update 2011-03-25, 10:30:
We are in room 206. Everybody who is not presenting is getting in big troubles.

Greasemonkey Script: jQuery AJAX Latency Display
On 03, Mrz 2011 | inGeneral | vonJohannes Hoppe
Displays the time between two AJAX calls that were made through any jQuery function. It binds to ajaxStart() and ajaxStop(), so jQuery is used and required.
We use it for a manual UI tests where time is an acceptance criteria.
