+1 both for sarcasm and usefulness!

Yeah, I wish I'd seen the "top ten signs" (#9) a long time ago. It might have saved me from blowing my early 20s on a good idea that I just couldn't execute on. (It was basically Google Base, but with no commitment from the friends I asked to help me, with no successful sites under my belt, and using only the primitive tools of 1997. Oh, and the unworkable resource-cost-to-impression-revenue economics of that era as well.)

I wish I'd also been slapped in the face with the observation (linked to from somewhere on news.yc) that a great idea with no execution is worth about $10.

So good, it has been posted before:

I do this because I found the comments in the other one useful, not to be a dick. It is a dick-move, though, but at least I'm honest.

Good list, but I disagree about the 'piping cats' point. It always seemed like premature optimization to me. Also, the cat at the beginning of the pipe can help readability.

Something like

cat file.txt | grep some_regex | sed ...

Versus

grep some_regex < file.txt | sed ...

I like the first version more, it kind of reads like "take file.txt, then grep, etc". You read it and immediately know you will be working with file.txt. The second one, it's not as obvious.

Just a nitpick, sorry for the long post.

I agree. Among other things, it allows you to easily substitute head or tail for cat when building up a pipeline to work on the output of large files.

Good point
