Login to Longhorn

With the release for Mac OS X Tiger scheduled for Friday Microsoft has recently released some infomation about their Longhorn!

I don't think Windows users are in a hurry to upgrade their OS. Microsoft is always known for building vaprowares but I am sure we don't want shell out bucks to upgrade to the newer OS. The press release also notes that Longhorn can run in slower machines in XP like mode. If that is the case I would just install XP and live with that. Why bother at all for the new OS?

If Microsoft can give recommeded system requirements for Longhorn then it would definitely be a huge welcome.

Compare files/directories

Today I was hunting down some strange problem and would have to find some nice tool to do directory comparision. ExamDiff Pro did an excellent job. I would highly recommend this for binary directory comparision.

You could also use KDiff3 since its a freeware!

WebSphere Portal Server 5.1

I was fighting with a application enviorment migration from WPS 5.0/ to WPS5.1/RAD6.0. I found some interesting facts that I thought worth scribbling it here. First of all RAD doesnt have support for Portal/Portlet development. The good news is that IBM has released an update for this in its newst RAD, so just update the RAD enviroment always to the newst and greatest!

If you have a Portlet application there are few tricks you must adopt to migrate the same to the newer enviorment. First create a blank Portlet application using RAD 6.0. Then manually copy all your source files from the old project to new project. Then make sure all dependencies are configured as of the old project. While copying portlet.xml and web.xml make sure you overwrite the new files with your old files. DO NOT overwrite portlet.tld, you must use the new portlet.tld. Also while copying lib directories DONOT overwrite with old JAR files.

If you follow these steps then migration to newer enviorment must be a peace of cake. I recommend atleast 1.5 GB RAM for running RAD 6.0 and WPS 5.1 (or even WAS 6.0)!

How to setup a web/ftp server @ home? (Dynamic DNS?)

Have you wondered what is Dynamic DNS service is?

Generally we know how DNS (Domain Name Server) works . Any major website is usually associated with a static ip address. The name is mapped to a single ip address and it wont change frequently, most servers have static ip address. In order to obtain a static ip address for your home you may have to pay additional charge to your ISP.

At home we normally have a high-speed (or dial-up) connnection with dynamic ip adress. By dynamic we mean that each time you connect to your ISP you will be given a different address. Since there is on single ip address it would be impossible to host a web server and ensure availability of the system. The dynamic DNS service provided by,, etc. In dynamic DNS service works by installing a client application on your home computer and monitors your ip address continously. If your ip address changes the client maps your domain name with your "current" (home) ip address. So any browser trying to resolve your domain will find you! As simple as it can be!
