Remote Control Your Computer Using Hardware or Software

The one problem common to computer users who work on two or more computers simultaneously, is the challenge to minimize the effort involved in moving from one computer to the other. There are multiple ways to overcome this, from using somewhat expensive hardware to using freeware applications.

KVM Switch

KVMSWITCH.jpg A KVM switch (KVM is short for keyboard, video, mouse) is a device that lets you control multiple computers from a single keyboard, video monitor and mouse. I wanted to work simultaneously on my laptop and desktop so went and bought myself a two-port KVM switch These devices come in two modes, automatic and manual. I recommend paying a little extra and going in for the automatic version that lets you toggle between computers with keyboard hot keys.

On the downside, a KVM switch is useful if and only if the two computers are located right next to each other, and are not networked (highly unlikely). Even if the second computer is in the next room, a KVM switch won’t do you much good, unless of course you are ok with having long cables running through your house or workplace.

Virtual Network Computing (VNC)

VNC transmits the keyboard and mouse events from one computer to another over LAN or the Internet. There are many free utilities available that you can choose, I tried TightVNC it is very user friendly and an IQ of -1 should see you through, if not then read A guide to building a software KVM switch.

TightVNC is just one of the utilities, both paid and free, that let you remotely connect to another PC. CrossLoop, IRemote, Windows Remote Desktop, or GoToMyPC; are just a few of the other applications you can use to access computers remotely.

ShowMyPC on ManuKLhanna.comMy personal favorite though is ShowMyPC because it requires no no installation or configuration; ShowMyPC combines VNC remote access technology with an open-source SSH forwarding client. The person manning the remote computer just needs to download the standalone software (less than <1 MB), and allow you access with just a password (no IP address required). This password is unique for every session and can be provided to you by the remote user over e-mail, phone or chat.

Ideal if the person at the other end isn’t a geek.

Verify an E-Mail Address

I’ve always wondered if this were possible, after all an e-mail address doesn’t have an IP which you could ping and see if it actually did exist. But surprisingly, one can indeed validate an address without sending an e-mail to it.

The Lifehacker blog has a post about a service that connects to the respective e-mail server and checks if the user, format, and domain that form the e-mail address you specify do actually exist. I concocted five fake e-mail addresses and checked their validity using this service. The service was spot on and gave a “bad Request” message for each. This just might come in handy so worth including in < my account. (via Lifehacker)

Batch Manage Pictures with with Fire Uploader

Google’s Picasa Web Album service lets you upload a maximum of five images simultaneously. So if you want to upload 50 pictures you will have to upload them 5 at a time This isn’t a tedious task but I’ve personally tried it and found it to be quite boring.

Enter the Fire Uploader extension that lets you drag and drop multiple images into your Picasa web account. The best part about this extension is that besides Picasa, it also allows you to upload to Flickr,, Youtube
