I've been at Nanyang Polytechnic since 9.40am this morning, attending the Web Services Developer Day seminar.
There were a total of 3 speakers, 1 from IBM, 1 from Microsoft and 1 from Sun. The IBM guy's name was Brad, he's from Australia. Basically, he was speaking in a monotonous manner, and I almost fell asleep from the talk. He was droning on and on and on, as if he's a machine gun or something.
The guy from Sun was the most engaging. He said his name is Chuk, though he pronounced it as Chuck. He's quite good a speaker, though he kept hemming and hawing, in our vernacular (uh, ah, etc).
After lunch, the labs workshop started at 1.30pm. Attendees were given 6 disks. 2 CDs of Visual Studio .NET Professional, 60-day trial. 1 CD of Microsoft Visual Studio .NET prerequisite.3 CDs of MSDN Library for Microsoft Visual Studio .NET 2003 and 1 DVD of Microsoft DevDays 2004.
The labs were hands on labs workshop of Web Services interoperability with Microsoft Visual Studio .NET. In addition, there was an interoperability exercise, with Java consuming the web service created in C#, using The Mind Electric.

In 2017, with the release of Delphi 10.2 Tokyo, Embarcadero introduced a specialized implementation of the Observer pattern into the System.Classes unit. While it has been in the wild for 9 years, it remains a "hidden" architecture for many, primarily because it serves as the invisible engine behind LiveBindings. Other than live bindings, you can also use the Observer pattern as a way to update component settings to the Windows registry, an .ini file, or persist it elsewhere.
