Xin Li When compiling the kernel on a multi-core system, there will be multiple threads or processes running at the same time. So concurrency issues will become an issue. However, when there is only one core in the processor. Will there still be problems? gnas

Jainesh Kumar I am trying to split the work of the loop into two threads. I am using the ExecutorService to create a second thread and the main thread as another thread. I'm using a counter to stop the loop when it reaches a certain value, but I can't synchron

Kirill I'm developing an API with Flask and SQLAlchemy and here's what I want to do: I have a client application that works on multiple tablets and has to send several requests to add content to the server. But I don't want to use automatic rollback at the end
Ohas I have a client connecting to n different servers. So, I am creating n different channels. Because I have more than 5000 servers. I used 10 event loops and only one event loop group. Also, each channel has a separate pipe. I already know there won't be an
Wu Yanzu In Java I need to know ConcurrentHashMapwhat type the key or value is and then how to do it in clojure. I could create a new type ConcurrentHashMapwithout specifying the key or value, but I think it would perform better if the type could be specified.
