SQL summation without coalescing null addenda to zero. The sum result was a null. This had been going on for years. Oops!

The lesson/mitigation was to add a NOT NULL attribute on top of a DEFAULT 0.

I have to disagree with Hoare sensei there. The number is nowhere near a billion. I personally know of one case that totaled to a billion.

This is good but please, to preserve your own sanity, first design the table struct properly to capture all attributes you can think of in separate columns and add the appropriate primary key. Then add the extra JSON(B) column for unforeseen data. Keep iterating till the table is still small.

Not necessary because this is realised to a certain extent through safety standards. Certified earthquake proof. Done.

Now, in this case, FDA approval should include software standards that prevent this scenario. Done*.

It is interesting that Mr. Landis mentions entropy (in Thermodynamical sense I hope). I have always wondered what it means here, in this solar system. Assuming the solar system has negligible energy flowing in, what does it mean when life on earth is reducing entropy in this system? We are tipping the balance by assimilating atoms in a more orderly fashion with each birth. This means something bad is happening somewhere close-by. ;-(

Security on bare metal OS is a hard problem.

Square or cube that to get an idea of security in virtualization.

You are approaching from the wrong angle. How much was the exploit "worth" to the company?

Some people want to watch the burn. An attacker could make it known anonymously and LastPass will never recover from that onslaught.

Then my friendly advice is to add an "/s" after your comment so that you leave no doubt about the interpretation.

> Elasticity is how much you can deform (stretch) an object, before the deformation is no longer reversible. Think of a rubber band, you can stretch it a little, and it returns to its original shape. Stretch it a lot, and it breaks down and does not return to its original shape. > Plasticity is how much you can deform an object before it breaks. This is the snapping point in the rubber band, where it completely breaks.

These both are completely false.

Elasticity is the idealistic property of a solid material to get back to it's original shape after a deformation force is retracted. (property of most solid metals where stress is much below the yield point)

Plasticity is the idealistic property of a solid material to stay in the deformed shape after a deformation force is retracted. (Plasticine)

It is unclear what exactly happened. And my guess would be that it was deliberately left out because the blogger initiated the convo.

One should try it in the US after having his visa expired there.
