The difference between requestIdleCallback and requestAnimationFrame
Page smoothness and FPS The page is drawn frame by frame. When the number of frames per second (FPS) reaches 60, the page is smooth. When it is less than this value, the user will feel stuck. 1s has 60 frames, so the time allocated to each frame is 1000/60 ≈ 16 ms. So when […]
[Vue] Tens of thousands of words explain event processing vividly
Hello, I am Xiao Suoqi. The carefully crafted Vue series tutorials are constantly updated. If you want to learn & consolidate & avoid pitfalls, let’s learn together~ Event handling Basic usage of events Highlights Bind events using the v-on:xxx abbreviation @xxx, where xxx is the event name (review: v-bind is abbreviated with colon:) The callback […]

AIDL for Android cross-process communication
Foreword There are many methods of cross-process communication in Android, such as broadcast, ContentProvider, AIDL, etc., each of which has its own scope of use. Moreover, AIDL is more like Java’s ServerSocket communication mechanism, which requires a resident server and a client that calls it. The current disadvantage of AIDL may also be that it […]
Java thread pool test-Spring-idle threads will be queued
Conclusion Scenario: If you want to reduce queue waiting as much as possible (set the thread queue length to 1), use the thread pool directly for processing, and set the number of concurrency to be sufficient (the example sets 4 threads). It is expected that within 4 requests, no one will enter the waiting queue. […]
AIDL+MemoryFile anonymous shared memory realizes cross-process large file transfer
Note: The content of this article is reproduced from the following article: Using AIDL to efficiently transfer large files across processes AIDL AIDL is a way to implement inter-process communication (Inter-Process Communication) in Android. AIDL‘s data transmission mechanism is based on Binder. Binder has a limit on the size of the data to be transmitted. […]
