At the moment I’m of the opinion that writing tests might be the worst use case for AI. Unless you’re ensuring that the tests fail for a useful reason of course! Tests that only pass are worse than no tests at all.

Maybe not in your case but I have a feeling that this use of AI is going to lead to some subtle production bugs in the future. It's easier to write good tests than review tests written by an AI.

Just your annual reminder to raise a glass to Stanislav Yevgrafovich Petrov who on this date in 1983 saved ALL our lives when he decided to wait for evidence in stead of passing on the message that could have caused armageddon.

Did you know my Great Courses offering on The Many Worlds of Quantum Mechanics is available on Amazon Prime? I think I have a couple of other courses there, too. They don't tell me anything.

The Many Hidden Worlds of Quantum Mechanics is about why we should take the Many-Worlds Interpretation seriously, as arguably the best explanation of quantum mechanics, the science of matter and energy at the atomic and subatomic scales. In 24 fascinating lectures, Professor Sean Carroll guides you through the history, reasoning, and implications of this bold idea.

When 'someone' has the ability to rifle through check bags and pull valuables, it's not just a property crime, it's a security breach.
If they can take things out of bags,
they can also put things into bags.
Does #SpiritAirlines care about security?

One of the coolest benefits of flying on #SpiritAirlines is their crew goes through your checked bags and removes things that you don’t really need, like audio interfaces and bluetooth speakers.
And they donate your valuables to a worthy charity! (right?)

When items from a checked bag are stolen, it’s a sign #SpiritAirlines' security is faulty and your safety is at risk
If someone can access your suitcase,
go thru its contents,
and TAKE ITEMS WITHOUT DETECTION,
what other ‘INSECURE’ things
could someone do with your luggage?

We’re not denying that #SpiritAirline’s baggage crew STOLE three items worth $130 from your checked bag.
We're rejecting your request because you didn’t tell us about the crime within 4 hours of landing! (even though you landed at 2am)

Spirit Air's cheap ticket isn't so cheap when you have to spend twice that amount ($130) to replace items their crew stole from your checked suitcase.
Don't forget the hours of time you'll waste on the problem.
