It has been over a week since the Apple Developer Center Web site went offline, with no indication of when it will be fully back. However, Apple has created a status page displaying an itemized checklist of what services are online. (Alas, you can’t click the icons to bring services up and down!) In email to developers, Apple announced that it is prioritizing the order in which updated systems will be made available. Certificates, Identifiers & Profiles, Apple Developer Forums, Bug Reporter, pre-release developer libraries, and videos will be available first, followed by software downloads and remaining systems. (Most Developer Center systems have since come back online.)follow link
Data Tables in Microsoft Excel 2008
Data Tables let you see how the results of a formula change as its underlying variables change. After entering data, select the entire table and choose Data > Table. Then tell Excel which row input cell and column input cells you want the table to use. Finally, click OK. Excel will crunch the numbers and present a new Data Table.
