Bought a TP-link AC1200 wifi adapter long before and not used it so far. Yesterday, I find it again when I collected my old stuff. Since my old Dell laptop does not support 5G channel, and its built-in wifi adapter sucks, why not have a try!!!
tag : Ubuntu
I have two servers in DigitalOcean, and both of them are Ubutun with tomcat 7. Recently, I found that if I want to restart tomcat, it will cost me more than 5 minutes(No errors during this). And the worest is(almots half an hour):1INFO: Server startup in 1497026 ms
I have many servers, which run Java Web applications. For development, I like Jetty, but for production, I prefer Tomcat7 now. In ubuntu, you need root permission to use ports under 1024.
Recently, I always have work in Ubuntu servers. And sometimes when I tried to output a timestamp from server side to front end, I find something is “wrong”. Such I want time in EST, but the default is UTC.
