The Right Brain vs Left Brain test … do you see the dancer turning clockwise or anti-clockwise?

If clockwise, then you use more of the right side of the brain and vice versa. You can try to focus and change the direction; see if you can do it.

As for me, I see the girl dancing anti-clockwise all the time, though can make her dance clockwise. Most of my friends told me that they see her dancing clockwise. While few commented that they are not sure which side, as at times they see her turning anti-clockwise and at times clockwise, meaning what(?!), they are as practical as they are fantasy based [:-)], or perhaps not decisive [:-p] and cannot make up their mind!

Now ain’t that cool …. I mean the whole concept and of course the physics and coding behind this simple, yet sophisticated interactive game.

According to a site NerdTests.com, here is what I have scored:

Though personally I think I am more of a geek than nerd. Wanna see how you score —-> head here.

Well, try spending time in First Life (FL) … it’s even more realistic and can be even more disorientating than the Linden Labs artificial reality that is Second Life (SL).

There are a number of advantages that FL has over SL - no server lag (unless you’re hung over) high resolution imagery with no performance cost, a client you can use everywhere (even when there is no ‘net access) and no need to log out when it’s time to eat.

In 2003, IBM began releasing ThinkPad laptop computers with integrated accelerometers and associated software to protect the hard disks when the unit is dropped. Enterprising hackers from IBM and elsewhere have worked to develop modules for the Linux kernel to take advantage of these sensors. On-screen display orientation, desktop switching, even game control and real-time 3D models of the tilt of the laptop are now available. This article presents a new twist — knock codes — and a simple program to run commands when specific knock codes are detected.

For the first time, you can hit your computer and get a meaningful response! Using Linux® and the Hard Drive Active Protection System (HDAPS) kernel drivers, you can access the embedded accelerometers on Lenovo (formerly IBM®) ThinkPads, then process the accelerometer data to read specific sequences of “knocking” events — literally rapping on the laptop case with your knuckles — and run commands based on those knocks. Double tap to lock the screen, and knock in your secret code to unlock. Tap the display lid once to move your mp3 player to the next track. The possibilities are endless.

More here on how to accomplish this on your Thinkpad.

Funny indeed but do I agree with this humour. I think NO.

If I find a lady sitting with us, men, and able to engage in conversation, I am all available to hear out her opinion and even have a debate with her if there is one.

The exception being if she is blonde … yups, it is better she stays quite and come up with some jokes time to time as to keep the conversation little more interesting.

Matt Perry has cool article on what he calls “wardriving” - roaming around with GPS tracker and looking around for WiFi access points and then marking them on Google map. I am definitely going to give this a try in future, for fun, as he does, so not to forget this post I will re-post it here. One thing for sure, instead of using GPS tracker that connects to notebook via serial port, I will prefer to have some PDA which is GPS enabled and connects to notebook via Bluetooth or USB … how hard it is going to be to make it work with Linux! And, yes, I will have probably either SUSE or MEIPS distribution running on the notebook, instead of Ubuntu.

Wardriving is fun. Going around the neighborhood and mapping all the wireless networks may be nothing more than a geeky hobby but it can sure teach you alot. And viewing the results in Google Earth is icing on the cake.

I’ve used NetStumbler on windows and this works great but since my computers at home are now nearly Microsoft-free, I had to relearn the process on Linux. It breaks down into a few easy steps:

1. Install the drivers for you wireless card. On my HP laptop with a Broadcom card, I followed the instructions on the ubuntu forums which worked great with one exception: the driver link on that page doesn’t have a valid md5 sum so you can download it from this url instead
2. Install gpsd. This is the software that talks to your gps unit and is available in the ubuntu packages through apt. The one hitch is that I had to set up my Magellan GPS unit up for the correct baud rate and NMEA output. Once installed, I connected the GPS unit via a serial port, turned it on and ran gpsd /dev/ttyS0 to start the gpsd server.
3. Install kismet, the wireless packet sniffer. The version in the ubuntu repository is not recent enough to support my Broadcom driver so I had to download the latest source and compile it with the standard configure, make, sudo make install . Then I had to edit the /usr/local/etc/kismet.conf to reflect my system configuration; I changed the suiduser, source and logtemplate variables. Once configured, you can start it with the command sudo kismet.
4. Now drive/bike/walk around for a bit with your laptop and gps unit. When you’re done, shutdown kismet and you’ll have a bunch of fresh logfiles to work with.
5. The main kismet log is an xml file containing all the info on the available wireless networks including their SSID, their encryption sheme, transfer rater and their geographic position via gpsd. I worked up a small python script, kismet2kml.py (based on a blog entry at jkx@Home), to parse the logfile into a KML file for use with Google Earth. It could certainly use some tweaking but it’s a start. To run it, give it the kismet logfile and pipe the output to a kml file:
   kismet2kml.py kismet-log-Jul-03-2006-1.xml > wardrive.kml
6. Now fire up Google Earth (Linux version now available!) and load your KML file.

Also, as James Fee points out, posting your data as KML files means that the data can be integrated into a growing number of kml-ready apps including google maps (just upload the kml and point your browser to http://maps.google.com/maps?q=http://your.server/wardrive.kml).

Another neat application I’ve found for dealing with kismet logs is the kismet2gpx script for converting the kismet gps tracklog into gpx. Since most gps units have pretty tight limitations on the length of stored tracks, logging them to your laptop with kismet could be an effective way of creating detailed tracks on very long trips.
