I use it on all my domains, and check it on all inbound mail. I especially make sure i define no servers are valid for several domains I have that are web pages only, or use for throwaway e-mail addresses (i receive e-mail at that domain, never send from that domain.)

I do support a domain hosted on google apps and setting it up for that ends up with a less firm ~all option that allows bogus senders to slip through.

I can see SPF fails in my logs so it looks like many other domains are using it as well.

I use KeePass on Mac and Windows. Note that the Windows version has a 1.x and 2.x branch. 2.x database is different than 1.x. KeePassX only works with the 1.x database format only.

I use dropbox to keep the password in sync between mac and windows. I also use dropbox with linux as well.

"is revealing a paradox: the gas often called a silent killer could also be a medical treatment."

Not much of a paradox. Every medical treatment suffers the exact same paradox. Morphine - great pain killer. Too much and it silently kills you. Anesthesias are the same. Cancer chemo treatments come very close to killing you, a small overdose may do it. Too much tylenol? Liver disease. Too much advil? Kidney problems.

I love how the comments immediately blame Apple for all of this. How is this any of Apple's fault?

PALM complained about APPLE to the USB-IF. Apple re-tweaked iTunes, their own software, to verify the devices claiming to be ipods were really ipods. They didn't claim copyright infringement, they didn't issue DMCA notices, they didn't make patent infringement claims, they just changed their software to make sure devices they support were actually devices they were modifying. Palm makes it's computer connections lie, and it's Apple's fault. Awesome.

Apple is not the most open company around, but if openess is what you want then don't buy Apple, it's not like you're forced to.

I'm not really sure why people whine about the iPod not being open. It doesn't lock you in to the iTunes store, or DRM stuff, even on video. I buy most of my music from EMusic then Amazon MP3 store then finally iTunes. It'll accept music from peer-to-peer networks as well.

90% of my videos are ripped from DVD and have no DRM. Works fine on my iPod and Apple TV.
