When we are typing, we often encounter caps lock keys, resulting in input errors. We can set the system to make a noise when we press the CAPS Lock button, but this does not allow the CAPS LOCK key to turn off, what if we want to shut down the CAPS LOCK key? Today's little compilation teaches you how to use the CAPS

Implementation ideas:The Windowmanagerservice Loop reads the following key messages and distributes them to the window, filtering the messages in the Phonewindowmanager.interceptkeybeforequeueing method before the message is distributed. Therefore, the implementation of the message before the distribution of the Interceptkeybeforequeueing method to listen to the current key is the volume down key, if the current state is the lock screen state, and the

I am using the Samsung i9220 android system 2.3.5The precondition for this information leakage is that the mobile phone has enabled the screen unlocking setting function and is bound to a google account or password protection.By default, you need to enter the unlock password or pattern after the mobile phone locks the screen to enter the mobile phone.Below is my cell phone screen lockBy default, there is only one "emergency number" at the bottom of th

Note that the first call is spin_lock_irqsave (), but then the release of the lock uses spin_unlock () The second time to obtain the spin, it is required to use the spin _ lock_irq (), but the release lock uses the spin _unlock_irqrestore (), why? Static long _ sched Sleep_on_common (wait_queue_head_t * q, int state, long timeout){Unsigned long flags;Wait_queue_t wait;Init_waitqueue_entry ( wait, current );

The realization of thought:The Windowmanagerservice loop reads the following key information and distribution forms. Filtering of messages in the Phonewindowmanager.interceptkeybeforequeueing method.Therefore, the implementation is to listen to the current key in the Interceptkeybeforequeueing method before the message is distributed to the volume key, assuming the current state is the lock screen state. And the key is the volume down key, and two tim

. The problem is that after redis is closed, it will always read the file Cache and write new data to the file. $ Strlen = file_put_contents ($ cachefile, $ arr); // write the cached File If LOCK_EX is not used here, when using this function in high concurrency, it may appear that one php has not completely written the file, and the other php will read it, the result shows that the returned content is not an array, and a new content is written, whi

Usually the computer has its own screen locking function, which can be set to protect the role of the computer to avoid being used, in the Ubuntu system, if you want to cancel the screen lock function, how to deal with it?

In most php development, the lock mechanism is rarely used, but in some cases, locks are required for processing. For example, if the cache data is lost, many backend data requests are generated, the backend may be suspended, and the lock mechanism will be useful. Here we mainly introduce the Memory Lock Based on semaphore. Because there is no extension implement
