I wrote a typing program with the thought of having the students at my school use it, but I realized that would be 600 connections if all the teachers in the school typed at the same time. I have a typing program where Firebase is used as a traditional database. The only time the Firebase receives a change is when users login or when they pass a typing test to update their profile as having passed the lesson. Looking for

问题 I have 7 csv files and one xls file. In the xls file I have 7 sheets (one for each csv file). I can create a data connection that will read each csv file into a given sheet. However, when I zip up the xls, and 7 csv files and send them to someone they are not able to open see the data in the xls file becuase it is trying to access the files on my computer (C:/Desktop/MyComputerName/file.csv). Is it possible to make this link relative? Is there a different way to access the csv file's content

Java app handling for connections getting dropped

落花浮王杯 提交于 2019-12-08 12:49:32

tcp connection in TIME_WAIT won't allow reconnect, java

梦想与她 提交于 2019-12-08 12:42:12
问题 After making a tcp connection to a server, I close my linux application and Socket.close() is called. Checking netstat -pant, I see the connection is in TIME_WAIT status.

I've played around -without luck- with the socket methods: set_so_timeout(), set_keepalive(), set
