optical receiving devices. The receiver with a rate of 10gbit/s has been applied, and the 100GBIT/S device has a laboratory sample. Optical amplifiers mainly include fiber amplifiers and semiconductor optical amplifiers (SOA), in which erbium-doped fiber amplifier (EDFA) has been widely used in practical projects, the current research hotspot is bandwidth over 80nm UWB EDFA and distributed Raman fiber amplifiers. Due to its small size, gain width and amplification, switch and other functions, S

Proactor and reactor in Aces Ace_select_reactor is the default reactor implementation that is used by all platforms except Windows and will eventually wait with the Select () system function on those systems. Ace_wfmo_reactor on Windows is the default reactor implementation. The implementation does not use the Select () multiplexer, but instead uses the WaitForMultipleObjects (). When using Ace_wfmo_reactor, some tradeoffs are needed: Ace_wfmo_reac

. Turn off standard input. The process is no longer able to receive any input, even if it is running in the foreground. REDIRECT standard output and standard error to file nohup.out . In other words, the nohup command actually separates the child process from the session it is in.Note that the nohup command does not automatically turn the process into a "background task", so you must add a symbol.Seven, screen command and Tmux commandAnother idea is to use the terminal

slices and threads occupy memory resources. In addition, each time a socket connection is established, a new thread is created at the same time to communicate with the socket separately (in a blocking manner). This approach has fast response times and is easy to control. It is very effective when the number of connections is low, but if a thread is generated for each connection, it is undoubtedly a waste of system resources, and if the number of connections is high, there will be insufficient r

It's a long story ... I recently got a MB SD Connect C4 Clone (a low quality one by its looks)The multiplexer I got shipped with the following firmware:os:2.2.2csd:2.03When I tried to use the MUX on this firmware in 03.2014 xentry, I am not able-connect to the car and kept getting Erro Rs. So I watched webmaster's SD connect videos and renamed the 3 update folders in C:\Program Files\sdconnect Toolkit and it W orked! Xentry was working well. The probl

The user process also needs to ask the IO operation to be ready from time to time, which requires the user process to keep asking.Asynchronous blocking IO (Java NIO):In this way, after the application ini
