Note (there are many shortcuts for PS to extract the high-light selections, and the method is different because of the version.) PS4 version before the shortcut key is "ctrl+alt+~", PS4 version after the shortcut is "ctrl+alt+2")
Sixth step: Press the shortcut key "Shift+ctrl+i" to reverse the selection
Step Seventh: Click the "Create new fill or adjust Layer"

If you see the Webcenter Space app (Webcenter.ear) from the WebLogic console, the session timeout (3,600 seconds) session timout is misleading and is not applicable in the case of webcenter space applications. If you update the value from the console, it does not affect the session time-out of the Webcenter space application. Then, the question is how can I change the Webcenter space app session timeout? The default session timeout in Web. XML is set to 45 minutes. There are two ways to change t
Sony PS VR device okay

with negative numbers or floating-point numbers as arguments, then the function will fall into a dead loop.
The following program uses an adorner function to ensure that the argument passed to the function "factorial" is a positive integer:
Def argument_test_natural_number (f):
def Helper (x):
if Type (x) = = int and x > 0: Return
F (x)
else:
raise Exception ("Argument") return

An interesting smart question: given 12 balls of the same size, only one ball has a different weight from other balls. How can we use tianyao to name it three times to find the unique ball, in addition, it is determined that the emphasis is light or not.
Number the ball, 1 ~ 12. extract 1 ~ The 4th ball is a group of A, and 5 ~ The ball on the 8 th is a group of B, and the remaining 9 ~ The ball on the 12th is a group of C
Weigh the balls in group
