When doing cross-platform network programming, the only API available on Windows that corresponds to the epoll/kevent style reactor event model is select. However, it has a limitation: the number of sockets passed into select cannot exceed FD_SETSIZE, which is set to 64.Therefore, select in Java’s NIO on Windows also has the same limit. Many services ported to Windows that use the reactor model face this constraint, which often gives the impression that server programs on Windows have weaker performance.This limit is clearly insufficient for developing a high-concurrency server. So,...

Recently I encountered a weird behavior where a strange webpage showing up every time when I launched my Firefox.The first thought came into my mind is that my homepage of Firefox had been tampered.

If you are one of those unlucky early internet users, you would remember how painful those days were; like our basic computer, the browser used to take forever to load, but nothing could diminish our excitement for the latest innovation i.e. the internet. Around that time Internet Explorer was the best we had. In fact, it enjoyed more than 90% of the market share in 2003 when Microsoft bundled its browser with the Windows operating system for free.However, things began to go downhill for the Internet Explorer in 2004 when security and speed issues continued to arise in the browser and Microsof...

However sometimes there are cases where the file association for .jar may be altered after a third party application installed. The executable jar may not be able to be started normally post that and it still doesn't work eve...

For a long time, there is a doubt among lots of Windows users especially those English speaking users, that is why Microsoft chooses Alt+F4 to close a window instead of Alt+Q.

Recently Microsoft answered this doubt.Raymond Chen, longtime Microsoft developer and semi-official Windows historian, said the reason is that not everyone speaks English. It doesn't work that way in many other languages. You have to choose a common key sequence which people fr...
