APEX in the Cloud
Wednesday, October 05, 2011
Live from the OOW11 Keynote
There you go, Larry comes on stage... now it will start to be interesting.
Great jokes of Larry about "False Clouds". Something like "you check data in, but you can't check it out!", "you take the plane and are in the clouds, but can't get out the plane/cloud anymore".

Updates on APEXBlogs
I only found a little time today to look a bit closer into these issues and am happy to share with you what is going on.
The reason for not updating the blog posts was that my package produced this error:
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00217: invalid character 160 (U+00A0)
Error at line 1
Although the Oracle database is running in UTF-8 and Google is sending the posts as UTF-8, it looks like it's not doing that with the blog names. The name "João Oliveira" has some bad characters which Oracle didn't understand. After changing this name in Google Reader the procedure didn't produce the error anymore and Oracle could parse the xml again.
Concerning twitter... that is a different story. It looks like the APEXBlogs is banned to use the Twitter API. As I didn't take out the twitter api calls from the hourly sync, we stayed banned and it got worse I guess.
Although I thought I followed the guidelines of using the API, I'll change the syncing of twitter message to do it less frequently so we aren't blacklisted again in the future. The syncing worked for many months, so Twitter must have changed their policies.
Today I asked Twitter to remove APEXBlogs.info from the blacklist so hopefully the twitter syncing will work again in a few days.

Google Apps desupport "old" browsers
Beginning on August 1, 2011, Google Apps support for the following browsers versions will be DISCONTINUED:- Microsoft Internet Explorer 7- Mozilla Firefox 3.5- Apple Safari 3After August 1, you may have trouble using certain features in Gmail, Google Calendar, Google Talk, Google Docs and Google Sites with these older browsers, and eventually these apps may stop working entirely.WHY THE CHANGE?To give users the best experience with Google Apps, we need the capabilities of modern browsers to deliver features such as desktop notifications for Gmail and drag-and-drop file upload in Google Docs.For this reason, beginning August 1, 2011, Google Apps will support the current and previous major releases of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we’ll begin supporting that version and stop supporting the third-oldest version.
