Hence why I've been denouncing fingerprint authentication as insane since the 1st halfbaked scanners started showing up in laptops a half dozenish years ago.
Iris scanners at least don't have you leaving your identity laying around everywhere you go; even if the UX challenges mean they'll probably never become mainstream...

The silly part is that leaving your password all over the place via prints, as real of an exposure as that is, fails to be the biggest exposure. Consider credit cards: I leave my credit card with wait staff, cashiers, and other service personal every week. I've yet to be exposed by these people who actually handle my card. My exposure comes because of compromised databases - where the crooks don't have access to the physical card.
I don't see where thumb prints alleviate this vulnerability.
The crook isn't after your thumb any more than he's after your physical credit card.
In fact, either of those items missing causes them to become worthless as they'll be reported missing.
The crook want the sequence of bytes - the electronic representation of those items.
I have to think security experts are aware of this - to keep pushing biometrics they must have a solution to this problem of which I'm unaware.

One advantage (of probably many) of biometric authentification is that you do not need to remember passwords.
I'd rather be phishing!

That seems to be a very tiny advantage compared to the all the disadvantages.

Trouble is, you can apply that logic to "having one single password for all systems" and making it "password"...

I've followed the government advice, my password is now "3 short words"

Now, my first guess would be "GinAndTonic"...

I vote GinAndBacon.

Yes, it is. I've been scanning my finger to log on to my laptop since I bought it two years ago, and do you think there is any way I can recall my password?

Is biometric authentication a different thing than "password" authentication ?
One verify that you are who you say you are (biometric); and the other one verify that you have access to a system (password)?
As "cool" as it looks in movies, stealing one person eye or thumb to trick a retinal scan or thumb scan it is not really practical or easily feasible.
I'd rather be phishing!

I recently answered a query on a LinkedIn discussion. It was simple enough about how/why/when to override hashCode and equals in Java.
I gave a simple answer - if you override either you should override both and that if the equality of objects is based on the state, then you should consider overriding them even if you don't intend to use the methods.
Well roger me senseless with a walnut branch! There really are some fuped people out there. I have read that ALL classes MUST reimplement the methods, if you don't care then just use a random number for the hash code, you can override one and not the other and even that it doesn't really matter.
I must stop doing this, it hurts my brain.
[adendum]
Latest answer was about you can only build meaningful hash codes from String values within the object. FFS.

On the bright side this frustrating experience gives you an excuse to 'drown your sorrows'.

Excuse? Why would I need one of those?

You don't have to offer the wife a reason when you slip on your hat and overcoat and head out towards the pub?
Perhaps you've an arrangement like I have where I go to the pub to pick up the wife.

Tonight we're out at a reception at a posh London hotel. All I have to do is turn up suitably dressed and it's freebies all the way until the 8th 'stop it, you're embarrassing me' and then she'll drag me home.

How is taking advantage of free booze an embarrassment to the wife?
Is she not a frugal person?

excuse, isn't that called today is a day that ends in y?

 That's pretty bad.
On another hand (one of mine, not yours), I had to wrap a class from Microsoft (.net) yesterday because it doesn't overload those and it is sealed. 
I think this week is the week of struggling with needlessly sealed classes.

Yup, seen that a few times as well.

I'm looking forward to someone forking .NET and removing the sealed keyword on a bunch of classes.

And adding virtual to pretty much everything that doesn't have it.
Personally, I'd be tempted to add a Dispose method to Object as well.

Wow. That's scary, and sadly continues to confirm my belief in the stupidity of most programmers.

I am dealing with a project where all the data model and dsl classes override both. I think I can find a way to blame you for this.
