Safe bike locking technique?
Given the recently exposed Kryptonite U-lock vulnerability, what are some ideas for a valid locking technique and hardware? This photo was taken from Sheldon Brown's website as the preferred locking technique. Is this still valid even with a U-lock? Is another method better?

Bike ≠ Car ≠ Ped.
He is using a U-lock in that pic.
And, that's one of the best methods. I have two U-locks (one NY Lock for frame-to-rack, one Evolution Mini for the front wheel-to-frame) mainly because I think that it's good to have two really sturdy locks. But, the cable plus U-lock as pictured is good because it requires a thief to carry two tools (at least) to take the whole bike.

What recently exposed Kryptonite U-lock vulnerability? Has there been a new one since the barrel lock/Bic pen debacle?

In that pic, even the seat is secured.
I use a $1 cable lock from Dollar Tree to secure my seat to the frame at all times.

U through the frame and rear wheel to a solid object, and cable through the frame and front wheel (preferably also to a solid object) is what I am using, as well as a small cable securing my seatpost.

You need a beefy u-lock around the rear wheel, just behind the seat tube, attached to a steel post that is set in concrete. Don't put a u-lock around any part of the frame, because crooks will attempt to use the frame as a lever to break the u-lock...turning the frame into a pretzel.
Use a cable lock (such as the beefier combo lock models) to attach the front wheel to a locking post or to the frame, or use a mini u-lock to secure the front wheel to the frame.
But, an experienced and skilled "pro" with power equipment can defeat any lock in ten minutes or less. Don't leave a bike out of your sight for more than ten minutes if it is worth more than a few hundred bucks, or is a bike you will miss.
A woman in my neighborhood locked a $4,000 bike to a rack outside the neighborhood library and was shocked to find out that evening that someone had used power tools to cut her $100 lock...well, of course...a $4,000 bike left unattended for nine hours is gonna disappear.

Hi! Karen from Kryptonite checking in. No, I can gladly say that there have been no new exposed vulnerabilities to our cylinders. As you guessed, there have been no barrel cylinders in Kryptonite U-Locks since 2005. Very sound lock-up guidelines given by several of you guys! When it comes to minimizing theft risk, there is strength in numbers (of any sort of lock used)...but best when using multiple Kryptonite locks (shameless plug)...
