In two months the Motorola Droid has gone from buy one get one free to $20 a piece to FREE. That's a crazy good deal on a pretty good phone (Droid owner myself). Either they're clearing stock because the Droid2 is about to be released or they really want to screw Apple and take away potential iPhone4 customers.

Grass roof.

I found these three points useful.

I've found another good place for suggestions is Amazon.com. I look up a book I like and scroll down to the "Customers Who Bought This Item Also Bought" section.

I like goodreads.com. It's more social network driven. You friend people and can keep up with what each other is reading. You can post your own reviews or just a 1-5 rating. It gives a list ala "other people who enjoyed this book also enjoyed ...". I like getting credit for everything I do, so the "books I've…

@Zenne: This actually brings up an interesting point. I suspect a "these dice have been lucky" experiment would not show the superstitious benefit effect. The effect is that of a subtle positive encouragement on the recipient's behavior.

@beercheck: Nice! Let's see Celsius do something that slick with Pi/2 radians.

It's not the bacteria that smell — it's their waste products. Killing the bacteria will prevent new waste from being generated, but it will not remove the buildup of waste already in your shoes. That waste will eventually wear away, but if there is a lot of buildup, I don't see this doing anything immediate for the…

Making 30 thousand employees all change their password, as my university just did, is a nuke where we need smart bombs. Better to have a system that targets employees for pwd change based on risk predictors, e.g. a login attempt from a non-regular IP address, a large number of failed login attempts, or it's…

Are 14 jugs really necessary?

What's the risk to the cd/dvd player head? It seems like getting some vaseline on the laser would be bad.

Clever trick. The fact that none of us will ever use this, doesn't change the fact that it is a fun post.

@rzd: It depends how much slack is in the chain. The chain should be short enough so that it will only reach the release point when the door is shut.

@nmillerche+lifehacker: I can't believe I'm saying this, but that was really cool.

@nerve11: Quick unless your hacker assumes no one would ever be dumb enough to use a two character password and skips those combinations, in which case it would be unbreakable!

The two minute rule should come before delegating. Also some items fall into a file for reference or tickler file category.

@dangerp: Allen also points out, and you've nicely illustrated, that lack of efficient downstream systems is what causes the pile-up. Making a new file cost time. Processing and cleaning my built up files cost more time. The black-or-white label it or trash it approach is too extreme.

I rather get a warning email sent to the backup email addy gmail asks for.

@infmom: The effects of folate (folic acid) are a current topic of research and not fully understood. There are some studies (ref below) suggesting folate can prevent cancer and other studies that show it can exacerbate existing cancers. Results going in both directions have been seen for colorectal, breast, and…
