Anything-sync-daemon (ASD) is a was a diminutive pseudo-daemon designed to manage target directories in TMPFS and to period ically sync them back to your physical disc (HDD/SSD). This was accomplished via a symlinking step and an innovative use of rsync to maintain back-up and synchronization between The other. One of the major design goals of ASD is a completely transparent user experience.Https://wiki.arc

As long as Mac devices and IOS devices use the same Apple Id,icloud, you can sync Safari history between these devices. But it all happens automatically, and sometimes a Mac or IOS device may be offline, and Safari history is in an unsynchronized state, where you can wait for icloud to sync automatically, You can also introduce this method today: Force manual synchronization of Safari (ICloud) history.

If the Win8.1 platform, users need to open the SkyDrive application (Win8.1 Update platform has been renamed OneDrive). At this point, Microsoft OneDrive has started to automatically generate OneDrive folders locally, synchronizing cloud data.

You can use the Sync feature of the fast disk, as long as the OneNote notebook is placed in the Sync folder of the fast disk (you need to specify at the time of installation), so as long as the file changes, the fast disk will be uploaded in real time. Also on another computer, just set u

a mutex is a mutex that can be created as a field for other structures, and a value of 0 is the unlocked state. The lock of the Mutex type is not thread-independent, and can be loads and unlocked by different lines.
Method
Func (*mutex) Lock
func (m *Mutex) Lock()
The Lock method locks m, and if M is already locked, it blocks until M unlocks.
Func (*mutex) Unlock
func (m *Mutex) Unlock()
The Unlock method unlocks m, which causes a run-time error if M is not locked.

At the time of development, we often encounter scenarios where it is necessary to execute or initialize once, for example, Singleton mode or initialization of the system when it is turned on. General language common practice is to use mutually exclusive operation to set the flag variable, by judging the value of the flag variable to determine whether to execute the relevant code; The implementation of the Golang la

Just looked at Golang's sync bag and saw a very useful feature. Is Waitgroup.
Let's talk about the purpose of Waitgroup: it can wait until all the goroutine execute, and block the execution of the main thread until all the Goroutine execution is complete.

Overview
Sync/mutex is one of the underlying basic objects of the go language, used to build synchronization logic between multiple goroutine, and is therefore used by a large number of high-level objects.Its working model is similar to the Linux kernel Futex object, the implementation is very concise, performance is guaranteed.
