InfoVis is very cool, and the price is right, thanks, Marc !
In 1997 I discovered, with delight, Plumb Design's (now ThinkMap) Visual Thesaurus: [^].
I visit the ThinkMap site often because of the literary, and etymological, content of the site, not to mention the crossword puzzles.
Equally fascinating to me are Edward Tufte's wonderful books on the history of information design, and the visual representation of quantitative data: [^]. On Amazon: [^].

"What Turing gave us for the first time (and without Turing you just couldn't do any of this) is he gave us a way of thinking about and taking seriously and thinking in a disciplined way about phenomena that have, as I like to say, trillions of moving parts.
Until the late 20th century, nobody knew how to take seriously a machine with a trillion moving parts. It's just mind-boggling." Daniel C. Dennett

Yes, the world is running short on bytes; we must shorten passwords to save the bytes for our children!
OK -- so these messages always piss me off.
I'm making a list that I'll post publicly to shame these organizations (including my bank) into changing their password policies.
Please send me a list of any sites you encounter with a restrictive password policy!

I hope at least permit symbols

I had to change my wireless passphrase because directv (new models connect wirelessly!) did not include the caret in the list of available symbols. It was time to change it anyway...too many blank looks (caret?) when guests were over.

Hah! I have worse: my Domain includes a hyphen. I know of two sites (one of them my bank) which will not accept email addresses with a hyphen anywhere - so to sign up I have to use a disposable email, then change the email address to the real one afterwards (which works, showing their programmers are lazy little buggers)

What about overly secure access policy?
So this company has e-billing allows us to go online to download our bills and w/e business. The thing is the bill only comes every 3 months, so I can never remember the password I set for this since I rarely log on.
So my first experience, I failed to login more than 3 times, at which they permanently lock your online account until you call them and ask them to unlock it. I had to call em up.
Second experience, I forgot my login again, but being privy of the quick and permanent lockout policy, I decided to play it safe and just reset my password. They popup some secret questions and I had a feeling that the quick lockout policy also applies if you fail those 3 times or more as well. They don't tell you whether it's case sensitive or not, and I was sure my answer content was right but kept rejecting my answer. Anyhow, I couldn't get it until the 3rd time. Phew! Made it. I reset my password successfully, and try to login with my new password. Duh duh duh!!!!! Another SECRET QUESTION. And of course, I couldn't get this after 3 tries.
I don't think even banks ask a secret question AFTER a password reset. I don't know why a company would lockout an account permanently. It makes sense to lockout temporarily, say for a day or something, but permanently until you call them is just a pain in the _ _ _!

That reminds me of my cable internet company.
Every time I call Rogers about something, they ask me what my mother's maiden name is. So I tell them. "No, that's incorrect." Ummm.. no it's not.. 
No, I'm not adopted. 
Of course they won't tell me the correct answer, and I have to go to one of their stores to fix this.

Better than the password situation, the US Social Security Administration has hired an outside service to authenticate - it looks like the same one used by Pop Money - when new users attempt to create an account. The criminal bastards use some kind of fancy web analytics to create questions that supposedly only the real individual could answer. When I tried to open an account to check on my potential retirement payments, it asked me for the current address of the psychotic female I divorced 25 years ago! I have no idea where she is, where she's been, or who she's defrauded lately, but I have no way to protest this crap, and can't get past it. It's the same outfit that blocked me from sending money from my bank to a dear friend in an emergency, and using questions about this same female! This crap ought to be a crime, but I can't even find someone to complain to!!

I remember that rant... I guess you never got to the end of it in any satisfactory manner...

Nope. As far as I've been able to determine, they've never fixed it. I've been back a couple of times, but keep getting the same crap. But what the heck, maybe I'll try again tonight!

hehe... that's the spirit!! And speaking of spirits, be sure to collect a scotch first!!

Hehehe... After 4 scotches ( I think ), I tried again, and this time no questions about the psychobitchfromhell. Yay! I got through, account established, and I verified that I have just about enough coming to me after a lifetime of working hard to starve slowly to death on dry cat food. Thank Bog for Obamacare!

My big problem is that every different site seems to have different rules. This one must start with a number, this one a letter, this one can't have #, the other can't have any special characters. So my password locker can't get fine grained enough with the random generation, I can either get all special characters or none.
Then you have the other wonderful problem... bugs. One of the financial institutions I use here have a wonderful password reset function. Either you call them up or you answer a handful of questions like "What was the last deposit amount?", "When was the account opened?", the last of which is one of the security questions you set up when you opened the account. The problem is that the site has a bug where the security question is blank. It just has "Answer the following question:" and is followed by a text box to type in the answer.
Brilliant I tell you!

Edit: sorry, I didn't see your link.
You're right, overly complex of hashing algorithms can have an effect on performance as the length of password increases.
As suggested in the article, I would be content with a 4096 byte password limit
