Javascript plugin for Eclipse

I waas looking for a Javascript editor and came across JSEclipse plugin from Interakt. Its a beautiful plugin and even has a all-features-enabled free version :).

The best things I like about JSEclipse are:
  • Code completion for JavaScript function and classes.
  • Code completion for JavaDoc.
  • Function and class names are displayed in the Outline panel for the currently open file.
  • Open declaration i.e. the famous F3 functionality
  • Error reporting
  • Warning reporting
  • Code wrap
  • Support for major JavaScript libraries
  • Code completion uses Rhino for better accuracy
  • Use of JSDoc and inline parameter comments to detect parameter type
  • Suggest parameters to be filled
  • Project dependent code completion
  • Reads all classes in current project
  • Reads classes in currently opened files
  • Scan current file for words
  • Reads XML files for class definitions
  • Add your own XML with class definitions
However, it works on Eclipse 3.1.x versions only. I have multiple Eclipse installations. It didnt work on Eclipse 3.0 ("Editor could not be initialized."). However with Eclipse 3.1.2, it was a breeze to work with it. Either create an Eclipse project, or add JS files to your existing project, and you are ready to go!

It appears to work based on usage - it remembers how an object is used and completes based on that.

Have u guys (and gals) used any other editor for Javascript? Do share your experiences here.

Installing Bugzilla on Windows

Bugzilla is the Bugs/Issues Tracking Tool from The Mozilla Organization. Version 2.18 is the latest stable release. There are couple of resources which guide a User installing Bugzilla on a Unix/linux machine. However, this entry describes a way to install Bugzilla on a Windows machine (W2K to be precise). This document guides you step by step through the installation process. First, get Administrative access to the machine on which you want to install Bugzilla. It should be a simple step. Usually, Users are given Administrative rights on Windows machine. However, if you dont have, contact your Administrator. Get Bugzilla Then download the Bugzilla from http://bugzilla.org/download.html . There are two ways of gettng it - through CVS or direct downloading the tar file. Remember there are no Zip files. However, any zip utility should be able to untar the Bugzilla. I download the tar file and untarred it using WinZip. I placed the untarred 'bugzilla' directory in my c: drive. So...

JSP Performance Tips

Here are a few tips to improve JSP performance that I have been using. If you have your own listing of the tips, plz share. Disable JSP auto reloading feature. Use thread pool for your JSP engine and define the size of thread pool as per application requirement. Use jspInit() method to cache static data Initialize the 'out' object (implicit object) with proper size in the page directive. Set the content length Give 'false' value to the session in the page directive to avoid session object creation. Flush the data partly Use StringBuffer rather than using + operator when you concatenate multiple strings Use include directive instead of include action when you want to include the child page content in the translation phase. Avoid giving unnecessary scope in the 'useBean' action. Use print() method rather than println() method Use ServletOutputStream instead of JSPWriter to send binary data Minimize code in the synchronized block Do not use custom tags if you do no...

How old are the daughters?

Two MIT math graduates bump into each other at Fairway on the upper west side. They hadn't seen each other in over 20 years. The first grad says to the second: "how have you been?" Second: "Great! I got married and I have three daughters now" First: "Really? how old are they?" Second: "Well, the product of their ages is 72, and the sum of their ages is the same as the number on that building over there.." First: "Right, ok.. oh wait.. hmmmm.., I still don't know" second: "Oh sorry, the oldest one just started to play the piano" First: "Wonderful! my oldest is the same age!" Problem: How old are the daughters?
