A big chapter of this life is the freedom of wheels

22 Jan Friday
I got my professional Australian license

23 Jan Saturday
Had my first drive with my wife in Baby’s Galore Taren Point

24 Jan Sunday
We went to the church and then purchase a GPS.
Had my first top-up of fuel in Caltex (Premium Petrol 98 RON).

26 Jan Tuesday
Had driven 120kms to Wollongong to celebrate Australia day with style =)
Had my first car noise when swerving at 100kph downhill.

I’m loving this freedom and very thankful

Wolfram Alpha is too academic and claustrophobic

Wolfram Alpha is probably a project designed by scientists that came from a science school.

It displays numbers, graphs, semantics and tables. I love how it presents information discovery like in the case of the term ‘apple’ where it displays the company and then the next option is about the fruit. I don’t know if it is using some form of page ranking or trending. Well apple as a brand is stronger compared to the fruit.

One other thing, I am stuck on the page and I get this feeling of being contained in a box. I guess it is backward to get all that I want from a single website. It feels like being in a library on your own with a huge book.

But then again, it is good to see an alternative to a growing behemont like Google. I just hope that this in not just a hype like Cuil.

Recovering Windows XP Profile

After doing a windows install on existing OS, windows xp is not very good in using existing User Profiles.This also happens when joing a new Domain.

To recover the old profile so you can get Outlook data and other Application settings, open the Registry Editor

Run > regedit

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

You will get something like S-x-x-xx-xxxxx…

Change the ProfileImagePath to the directory of your old profile : ie %SystemDrive%\Documents and Settings\your_username
