February 26, 2014, 12:10 PM — Samsung made the Galaxy S5 official on Monday at a Mobile World Congress presentation in Barcelona, touting a slimmed-down approach to the latest flagship's feature set and simplified design.

It's a small but notable departure for the South Korean company, whose devices all too frequently combine undeniable engineering brilliance with a glut of marginally useful features. Co-CEO J.K. Shin and other Samsung executives who presented at the event were eager to talk up the way in which the company had listened to input from their customers.

PowerBuilder 15 Classic Sneak Preview

Seem, that Sybase will jump directly from 12 into 15 for Powerbuilder.

Frederick Koh explains one of the feature in version 15 for WindowType value called: mdidock! and mdidockhelp! for the window object. Like values mdi! and mdihelp!, respectively, they allow child windows (sheets) to be opened with the OpenSheet functions. But these sheets will behave differently: they can dock, float and be tabbed like the windows you see in our PB.NET IDE. 

Adware vs Spyware vs Trojan vs Worm

This is a simple explanation:

Adware is a online advertisement, and have "no data steal" characteristic.
Spyware is same with Adware, with "data steal" characteristic
Trojan is stealth scripts but have no "reproduce themselves" capabilities.
Worm is like a trojan, with "reproduce themselves" capabilities. In other word in more vicious than trojan

Datawindow Control is the heart of Powerbuilder. This is the control to communicate between the Database and the client user interface.

This is the BIGGEST different between Powerbuilder and the other programming languages. In Powerbuilder, programmers start to make application from the database into datawindow control, then visualize into the other controls (like Dropdown, Radio Button, etc), column per column. Later, you can setup the properties for each column, like display properties, validation properties, etc.
