These Really Work!

Via my mom, who says she verified the following on Snopes:
Amazing Simple Home Remedies

1. Avoid cutting yourself when slicing vegetables by getting someone else to hold the knife while you chop.

2. Avoid arguments with females about lifting the toilet seat by using the sink instead.

3. High blood pressure sufferers – simply cut yourself and bleed for a few minutes, thus reducing the pressure on your veins. Remember to use a timer.

4. A mouse trap placed on top of your alarm clock will prevent you from rolling over and going back to sleep after you hit the snore button.

5. If you have a bad cough, take a large dose of laxatives. Then you'll be afraid to cough.

6. You only need two tools in life – WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

7. If you can't fix it with a hammer, you've got an electrical problem.

Yup, this is the kind of home I grew up in. Does that explain anything for you?

Public Key Cryptography Invented Earlier than We Thought?

Ask anyone interested in cryptography about public-key cryptography, and the names of Diffie, Hellman, Murkle, Rivest, Shamir, and Adleman will quickly arise.  They're the inventors of the concept of public-key cryptography as most of us know it.

Well, maybe not.  If this article is accurate, apparently the British government developed public-key cryptography independently and several years earlier than the six listed above.  The narrative sounds plausible to me, though of course I have no personal knowledge of any of it...
