How to mock an import
...ulate a side-effect that took some time. So I needed an object's method to sleep for a second. That would work like this:
sys.modules['foo'] = MagicMock()
sys.modules['foo.bar'] = MagicMock()
sys.modules['foo.baz'] = MagicMock()
# setup the side-effect:
from time import sleep
def sleep_one(*args): ...
How to prevent a background process from being stopped after closing SSH client in Linux
...hat every other app has done since the beginning -- double fork.
# ((exec sleep 30)&)

PPid: 1

bash: disown: current: no such job
Bang! Done :-) I've used this countless times on all types of apps and many old machines. You can combine ...
Colors with unix command “watch”?
...t know the flags or there isn't you can make a poor's man watch by:
while sleep <time>; do clear; <command>; done
It will have a bit of flicker (watch works "double buffered") but for some stuff it is useful enough.
You may be tempted to make a double buffered poor man's watch using ...
What does the 'static' keyword do in a class?
...s if they were instance members, e.g.
// Bad code!
Thread.currentThread().sleep(5000);
someOtherThread.sleep(5000);
That makes it look as if sleep is an instance method, but it's actually a static method - it always makes the current thread sleep. It's better practice to make this clear in the ca...

然后用bm *tol*给所有含有tol的函数都设置断点；
