  Turn on SecurityManager in Java

SecurityManager in Java is to check whether the application codes can access some restricted resource such as file, socket etc. This can be used in applications which have high security requirements. With this feature turned on, our system resources can be secured with only permitted operations. When JVM starts, it will first check whether the SecurityManager is on by checking the system property java.security.manager, if it's on, then an instance of SecurityManager will be created and it can be...

  Text editor vs IDE

A meaningless editor war Many people like to debate which editor is the best. The biggest controversy is between Emacs and vi. vi supporters like to say: "Look it's very fast to type in vi, our fingers no need to leave the keyboard, we even no need to use the up,down,left and right keys" Emacs supporters often downplayed this and said: "What's the use of typing fast if I just need to press one key and it equals to dozens keys you type in vi?"In fact, there is another group of people who like to ...

  Some tricks on PHP session

1. Session timeout problem There is a nuance we found with session timing out although the user is still active in the session.  The problem has to do with never modifying the session variable. The GC will clear the session data files based on their last modification time.  Thus if you never modify the session, you simply read from it, then the GC will eventually clean up. To prevent this you need to ensure that your session is modified within the GC delete time.  You can accomp...

  Emacs adventures

I have been using Emacs for over a year now. I actually didn’t learn a lot when I started using it (just the basics to get going and then some relatively common keyboard shortcuts), but lately I have been reading and learning much more about it. I’m so grateful by everything I’ve learned from different people on the net that I wanted to share a couple of things I’ve learned, and a simple major mode for editing AsciiDoc documents. As a long-time VIM user, I f...

  Java Doesn't Need to Be So Bad

I do a lot of Java coding and I enjoy it. I admit that there is a lot of typing, often a lot of boilerplate and getting even simple tasks done can involve too much work. Most of the tools that try to fix these problems trade one moment saved for another lost. Maven's XML based configuration file is a good example: Thank you for making my project easier to manage and I won't forget that you made me edit XML to do so. These are the things that you live with, these are the things you trade for ...
