问题 I have php file which consist of curl code so as to access an api. But when I upload this file on server and try to execute it via url no output is shown.

问题 I run an application on my Linux server, which gets data from big DB tables. For instance, for around 100000-200000 rows, the size is about 50M. But when I get data from table, the memory of the server is far greater, and after a "select" query, memory stays high, and then when I get data again, memory increases even more. Finally my application runs out of memory. It only takes 3 times to happen. The error status returned at that point is 500. The memory on server is 2GB, and I modified my

问题 Say we have a server which can serve only 4 HttpRequests at max at a time. If 10 Http requests come, what will happen? What are the various options?

Does load balancer take care of it? Does the developer need to take care of this in his code by building some queue? These questions were asked to me in an interview

问题 Trying to implement a test server in paramiko without having to modify the client for testing , I have stumbled across the problem how to close the stdout stream, making `stdout.read()´ not hang forever without going too low-level on the client's side. So far I have been able to communicate the completed command (simple text output to stdout) execution by: class FakeCluster(paramiko.server.ServerInterface): def check_channel_exec_request(self,channel,command): writemessage = channel.makefile(
