asynchronous

问题 If I had the below code, how would the variable service affect the asynchronous nature of the endpoints? Will the variable be shared? Or will it be locked when in use, thus blocking other endpoints from accessing it until the current one is done? I ask the above assuming that Service instances are stateless, i.e. it would be equivalent if I created an instance of Service in each endpoint. I am reluctant to do that because I don't know which is more time consuming, instantiating and destroying

问题 I have just started with Python, although I have been programming in other languages over the past 30 years. I wanted to keep my first application simple, so I started out with a little home automation project hosted on a Raspberry Pi. I got my code to work fine (controlling a valve, reading a flow sensor and showing some data on a display), but when I wanted to add some web interactivity it came to a sudden halt. Most articles I have found on the subject suggest to use the Flask framework to

问题 I am working with two recyclerview in single screen(For android TV).Each recyclerview have complex layout item.And it's taking time to load.I worked with asynclayoutinflator in activities. AsyncLayoutInflater inflater = new AsyncLayoutInflater(this); inflater.inflate(R.layout.main, null, callback); I want to know whether there is any ways to achieve the same with recyclerview. Problem I am facing is onbindviewholder is getting called before asyncinflation finished. 回答1: import android.content

问题 How React PHP handles async non-blocking I/O ? Nodejs uses its event queue which handles I/O on different threads. It uses libuv for this. As in PHP there isn't something like that, How React handles non-blocking I/O process on a single thread ? 回答1: React PHP provides the primary event loop of the application; you are still required to write your code in a non-blocking way since it is all on one thread. The possible solutions to this all revolve around using php differently than I am sure
