predictive typing

You can try a software called typing booster on Fedora. It helps user while typing. User can avoid typing mistakes and also avoid typing long spellings. If you are on fedora or centOS use the following command:

yum install ibus-typing-booster -y

I hope this package is made available for debian as well.

Yahoo Trip planner

Yahoo has shut down Trip planner and My Travel service that was part of "Yahoo Travel". They announced it around March 6th and shut it down on March 21, 2014. Yahoo did not send any mail to that effect or I must have missed it. Any way there is no reason to log in to yahoo anymore :)

tinyurl.com

Update:

I can see that I have got a mail on Feb 28 about this closure of Yahoo My Travel. 20 days notice is not enough even if I am not a paying customer.

Why not blog or text columns?

BLOB/TEXT columns are stored in an external hidden table. First 256B are stored inline in main table. Reading a BLOB/TEXT requires two reads. One for reading the Main table + reading from hidden table.
