Here is a screenshot from my Lenovo ThinkPad computer. The computer was running a self-test using the incorporated Lenovo utility, and I tried to abort this test by exiting that utility.
And then I got this dialog box:
Read it carefully:
If you continue, all the tasks … will be canceled. Are you sure?
And you have two buttons to choose from:
YES [Which means Yes — I’m sure, do exit]
or
NO, EXIT [Which means I’m not sure, do not exit].
Obviously the second button is intended to mean “Exit this dialog, not the utility” — but this is confusing as hell, since exiting the dialog and exiting the utility are opposite actions.
Would it kill them to use a simple “CANCEL” on the second button?
Here is one impressive calculating device: Washington Sabatini’s reinforced concrete calculator.
This complicated circular slide rule is one of the largest items in my collection. It comprises ten concentric aluminum rings covered with complicated scales and pointers. The rings are all movable except for the second largest; that one is fixed to the body of the device, as is the celluloid cursor overhanging the largest ring. The movable rings are rotated around the center of the device by use of the prominent crank handle that spans its radius.
For full details, and a worked out example of how to calculate the dimensions of a concrete beam under specified parameters, see this article on my History of Computing site.
Enjoy!
