We’ve all been troubled the tele-marketing people at some point of time or the other. It is indeed interesting to know that some banks have finally started maintaining “Do Not Call Registers”. Some telecom operators also provide the facility of registering your phone for the “Do Not Disturb Service”. I was planning to list some sites here, when I found this interesting blog.

Hope you guys find it useful.

I just realised that simple keyboard shortcuts which I termed discoveries in my previous post about Firefox, seemed discoveried because finding the keyboard shortcuts of an application can really be tideous. I’ve decided to post the url’s of all keyboard shortcuts of applications that I use. So here it goes:

1. Eclipse
2. Firefox
3. Internet Explorer
4. Windows XP

PS – Please feel free to either mail me or add new urls in the comments below, I’ll include them in the post.

Firefox December 18, 2006

I have been using Ctrl-Enter in Firefox/IE to reduce my typing for a long time. This keyboard shortcut takes care of prepending “http://www.” and appending “.com” to the name of the site you type in the address bar.

e.g. to go to http://www.google.com, you would go to the address bar and type “google” (without the quotes :-) ) and press Ctrl-Enter

I just discovered that Firefox has some other such address completion shortcuts.

It has Shift+Enter for .net addresses and Ctrl+Shift+Enter for .org addresses.

For a complete list of their keyboard shortcuts, you can refer this link.

Motherboard scare … December 16, 2006

I just assembled my PC with an ASUS P5B Deluxe/Wifi AP mobo. The very next morning I got the scare of my life, my PC would just not boot. I would not hear the any beep codes either, so I had no clue about what was happening.

For a minute I thought that I had a blown up motherboard :( . I decided to start checking out all components on the Mobo to figure out if a blown component was screwing things up.

As i plugged in each component at a time and tried starting the PC after plugging in each component, I realised that the two RAM slots were blown for some reason. When I shifted the DIMMs to the other memory bank the PC started working fine.

So if you guys have a non-responsive mobo on boot up with no beep codes, you might be interested in trying to reassemble all the components on the Mobo just to isolate the erring component/slot.

How to Slipstream a Windows CD with a Service Pack December 15, 2006

Slipstreaming refers to the process of integrating a Service Pack into the OS installation itself. Thus, all further installations of the OS will have the service pack preinstalled, thereby eliminating the tideous task of installing the service pack after the OS installation.

I was searching around for some good english to include in this blog, when I found this wonderful tool ! The tool is called nlite (http://www.nliteos.com/index.html). Its a neat tool which not only allows you to slipstream the service pack, it also allows you to customize your windows installation. It has support for burning a bootable image onto the cd/dvd.

So I guess anyone who reaches this blog and wanted to learn how to slipstream a cd, well I think you should be using this tool !! However, for the geeks out there, here are couple of links that I used to learn slipstreaming :
1. http://www.helpwithwindows.com/WindowsXP/winxp-sp2-bootcd.html
2. http://www.winsupersite.com/showcase/windowsxp_sp2_slipstream.asp (this site has instructions for burning the bootable cd with roxio as well as nero)
