AT & T Technical Customer Support

Sat, 13 Dec 2008 05:27:24 GMT

I am not able to receive emails send to my-number@txt.att.net as sms on my AT & T mobile.

why so:

mycomputer:~ myname$ telnet 66.102.165.114 25
Trying 66.102.165.114...
Connected to atlsmtp.cingularme.net.
Escape character is '^]'.

550 Invalid recipient: <408XXXXXX@txt.att.net>
quit
221 atledge02.cingularme.com ESMTP server closing connection

I feel helpless, after explaining my problem 30 minutes, technical support guy says:

    * Turn off & on your phone N number times
    * Take out your battery & put it in
    * Get new sim from nearest shop (free of cost)

I can't imagine what would happen to average non technical mobile customer

Jodhpuri Pyaaj Ki Kachori in Bangalore?

Mon, 08 Jan 2007 06:39:39 GMT

Jodhpur is famous for Pyaaj Kachori, Hot & Spicy Mirchibada (made from potato, onion, chili and gramflour) and Sweet Mawa Kachori. It is almost impossible to get such taste anywhere else in India. In case you are looking for similar taste in Bangalore, you should try "Jodhpur Sweet Home" at RT Street, BVK Iyengar Raod, Chikpete.

Google Maps Link to Jodhpur Sweet, Bangalore

WikiMapi link to Jodhpur Sweet, Bangalore

You are not going to get exact taste at this shop, but it is close enough (80%) to remind you original taste.

why?
Something wrong with human man interface design?
Can we have interface that take care of such 1% use case to make life simple of other 99%?

Joined yoga camp at http://www.ramakrishnamath.com/yoga.asp

Yoga exercise is not a challenge for me, the real challenge is to wake up early
at 5.30 to attend the yoga session from 6.00 am to 7.00 am for
one month (except sunday).
