Yeah any limiting like that would seem to decrease the entropy (unpredictableness of the data) and only serve to make it easier for hackers.

It probably means their COBOL data schema for the login database was configured to only allow alphanumerics and they're terrified of what might break if they edit it.

Now we just need to get the W3C to get access to hardware token support standardized and you can use the certs on your bank card, now that smartcards are the norm.

Then we need to make smart card readers ubiquitous; including an implementation that works well for with the fondleslabs that an increasing fraction of the population insist on using for everything.

Truth, but at least on the US-side of the pond this is already the case. Basically every cash register has a card reader; moving them into the house is not a terribly big jump.
I might be biased, though, since I use them daily for authentication.

At my previous job I had to use one with my PC periodically to send/receive encrypted email. My laptop (Dell Latitude E series) had a reader built in; but doing so limited my employer to a relatively small subset of potential models. The govt office I had to go to get my card reissued once or twice a year (they weren't allowed to be active past the contracts current end date) had an external reader about the size of a retail unit but lacking the pinpad (pin was entered on the PC). Not horrible as long as you're at your desk, but it meant you couldn't use an untethered laptop.
The govt had a phone solution (bluetooth?) but it apparently scored high enough on the PITA factor that the defacto situation was no govt email access on the phone except in emergencies.

The phone solutions are generally micro/mini USB-based, and vary wildly in quality. The laptop solution has been in place for ages, and will work on Windows natively back to 7 with no built-in reader required (an SCR3310 works fine for ours). I've been using token-based auth/encryption for almost 20 years and it can be a mild hurdle at times, but nothing that I wouldn't be willing to deal with to secure my bank account.
The bigger issue IMO is the lack of support in the browser standardization for support of token-based certificates. That's a big issue as the "current" solutions (Java or ActiveX) are not appropriate moving forward.

This morning...
Your password haven't changed the last 100 days. We strongly recommend you to change it. Would you like to change it now?
OK ---- CANCEL
Me: OK, let's see.
Type new password... not successful. Error message: Password must be between 6 and 9 chars.
Me:  Nevermind. If someone wants to hack it, it is easy enough that it doesn't matter if I change it every two days...

LEN (Transact-SQL)
Returns the number of characters of the specified string expression, excluding trailing blanks
So
> print len('hello')
> 5
and
> print len(' ')
> 0
Hands up who has ever noticed the "excluding trailing blanks" bit?
Up until an hour ago, not me. Which boggles my mind.

print len(' ')
Those look like leading blanks to me, not trailing blanks.

Exactly!

I see 2 trailing blanks and 2 leading blanks surrounding a single blank.

Now you are shooting blanks

Hmm. Actually, there could be an infinite number of zero width spaces[^] in that string in addition to the 'normal' spaces, if you're using UNICODE.
