ack -- better than grep

How did it take me so long to come across this? I found mention of it in Tim Bray's latest blog entry while I was examining his find/grep alias (by the way, Tim, I find the syntax below to work fine on my Mac)

I've spent my life using:
$ find . -name *.filetype -exec grep pattern {} \; -print

But no more! I spend a lot of time doing cross-platform development and haven't always had a good find/grep implementation (I'm looking at you, Windows and have never liked cygwin) so this tool will come in handy.

I wish Kindle took as large a leap for...

The Smart Alec Backpack is cooler than you. Even cooler than: TOM BIHN

I've owned one of Tom Bihn 's messenger bags before, and I can attest to the quality of the workmanship and attention to detail. I went with the Smart Alec over a Timbuk2 H.A.L. 2011 for both the simplicity of design and more importantly, molecularity of the inside; I can attach dedicated laptop protection or remove it for maximum empty volume for hiking or other activities. Now I have to wait for it to arrive!
