You think you have a clever password, eh? Well, sorry, guest123 just ain't gonna cut it anymore. Hackers* can crack your English-word-plus-number based password in a matter of hours. With much of our lives moving online, through email, Facebook, online photo albums, banking, etc, Farhad Manjoo's tips on creating invincible passwords is well worth reading. His tips basically boil down to to following two steps:

Start with an original but memorable phrase. For this exercise, let's use these two sentences: I like to eat bagels at the airport and My first Cadillac was a real lemon so I bought a Toyota. The phrase can have something to do with your life or it can be a random collection of words—just make sure it's something you can remember. That's the key: Because a mnemonic is easy to remember, you don't have to write it down anywhere. (If you can't remember it without writing it down, it's not a good mnemonic.) This reduces the chance that someone will guess it if he gets into your computer or your e-mail. What's more, a relatively simple mnemonic can be turned into a fanatically difficult password.

Which brings us to Step 2: Turn your phrase into an acronym. Be sure to use some numbers and symbols and capital letters, too. I like to eat bagels at the airport becomes Ilteb@ta, and My first Cadillac was a real lemon so I bought a Toyota is M1stCwarlsIbaT.

I used to use a single password for everything, from banking to my Unix account at work. It's a miracle I never had a break-in. I now use several passwords, all completely scrambled based on the formula above. Now you, like me, have no excuse not to keep your online life securely locked up!

*Yes, I know that a cracker .NE. haX0r, but most people think "cracker" means something else, entirely.

I use LastPass. That way, I only have to remember one password (and I use the type you describe) but LastPass generates gobbledegook passwords for all my other accounts (email, bank, forums, etc). I don't think LastPass would work for a UNIX account, but I highly recommend it for everything else.

I've recently jumped on the 1Password bandwagon, and so far I really like it. It integrates very nicely into Safari, so you just have to remember your one master password and it autofills any web page with the appropriate password for that site. And it does let you store arbitrary secure information of any sort, not just web page passwords, so it's good for encrypting unix account login info or medical record numbers or insurance information, etc.

The best part is that it works perfectly with Dropbox for synchronization between machines. Any accounts logged into on my laptop propagate the login info securely to my desktop, and vice versa.

### On the Height of J.J. Barea

Dallas Mavericks point guard J.J. Barea standing between two very tall people (from: Picassa user photoasisphoto).

Congrats to the Dallas Mavericks, who beat the Miami Heat tonight in game six to win the NBA championship.

Okay, with that out of the way, just how tall is the busy-footed Maverick point guard J.J. Barea? He's listed as 6-foot on NBA.com, but no one, not even the sports casters, believes that he can possibly be that tall. He looks like a super-fast Hobbit out there. But could that just be relative scaling, with him standing next to a bunch of extremely tall people? People on Yahoo! Answers think so---I know because I've been Google searching "J.J. Barea Height" for the past 15 minutes.

So I decided to find a photo and settle the issue once and for all.

I then used the basketball as my metric. Wikipedia states that an NBA basketball is 29.5 inches in circumfe…

### Finding Blissful Clarity by Tuning Out

It's been a minute since I've posted here. My last post was back in April, so it has actually been something like 193,000 minutes, but I like how the kids say "it's been a minute," so I'll stick with that.
As I've said before, I use this space to work out the truths in my life. Writing is a valuable way of taking the non-linear jumble of thoughts in my head and linearizing them by putting them down on the page. In short, writing helps me figure things out. However, logical thinking is not the only way of knowing the world. Another way is to recognize, listen to, and trust one's emotions. Yes, emotions are important for figuring things out.
Back in April, when I last posted here, my emotions were largely characterized by fear, sadness, anger, frustration, confusion and despair. I say largely, because this is what I was feeling on large scales; the world outside of my immediate influence. On smaller scales, where my wife, children and friends reside, I…

### The Force is strong with this one...

Last night we were reviewing multiplication tables with Owen. The family fired off doublets of numbers and Owen confidently multiplied away. In the middle of the review Owen stopped and said, "I noticed something. 2 times 2 is 4. If you subtract 1 it's 3. That's equal to taking 2 and adding 1, and then taking 2 and subtracting 1, and multiplying. So 1 times 3 is 2 times 2 minus 1."

I have to admit, that I didn't quite get it at first. I asked him to repeat with another number and he did with six: "6 times 6 is 36. 36 minus 1 is 35. That's the same as 6-1 times 6+1, which is 35."

Ummmmm....wait. Huh? Lemme see...oh. OH! WOW! Owen figured out

x^2 - 1 = (x - 1) (x +1)

So $6 \times 8 = 7 \times 7 - 1 = (7-1) (7+1) = 48$. That's actually pretty handy!

You can see it in the image above. Look at the elements perpendicular to the diagonal. There's 48 bracketing 49, 35 bracketing 36, etc... After a bit more thought we…
