I found this article interesting -

use ^incorrectword^correctword - will execute the previous command with the incorrectword replaced by the correct word

Ex:
lp -a |grep a --- Error
^lp^ls --- Correct the typo above

[Review] Qwiki

I just read abt qwiki from a link posted by my friend in Google Buzz.

The idea is really great. But, I felt that it gathers information from a lot of places - I mean social networking sites, organises them and then presents as a video.
But, is gathering the information - a breach of privacy - which you might want others to view only if they are really deserved (have the pain to click and search)... I don't normally want others to know me unless there is a need to know :)
