  GUI vs CLI: Operation vs Expression


Consider this user interface for a car:The goal of these interfaces is to make you operate something, and operate it efficiently and safely. The grooves and clicks and limits constrain the range of motion and the number of choices. The visual look heavily hints at how to actively use it. They are usually not hard to learn. More importantly, the learning curve plateaus. Once you learn how to drive a car, there’s not much progression after that. Boundedness is an im...

Greg Kroah-Hartman has released long-term kernel 3.0.20 and stable kernel 3.2.5. Both contain just a single bug fix that allows PCIe power-saving technology ASPM (Active State Power Management) to be used on systems with a BIOS that activates ASPM on some components, but states in the FADT (Fixed ACPI Description Table) consulted by Linux that ASPM is not supported. According to Matthew Garrett, who developed the patch, the change can reduce the power consumption of a Thinkpad X220 by 5&nbs...

This is an example. Your layout and text elements will probably be very different. In this example case, the ID of the button is “close”. <Button android:id="@+id/close" android:lay...
