"Lets create the folder first, and immediately start a rename operation, because writing the code that way will be easier"

I can't say that I agree with that design decision.

F = m * a

Look it's right there, force equals *mass* times acceleration. On earth, Scarecrow is 342kg * 1g when stationary. On mars Curiosity is 900kg * 1mars-g *when stationary*. Sure the vertical force on the tires is the same when standing still, but what about the force required to stop 342kg vs 900kg of inertia if you hit a large pointy rock at 1m/s?. In this case, with the same initial velocity, the acceleration would be the same but the force experienced by Curiosity's tires would be ~3x larger (ignoring any shock absorption).

But this trend is mostly *because* of the current console lifetimes. Most games are written to be ported to or from the main consoles.

Do you think that trend will change when PS4's and XBOX One's are becoming common?

If your customers are complaining about bugs, and those conditions are covered by your spec, then you are at fault for not catching it before giving it to the customer. You must verify that the delivered code matches your spec.

Either write automated tests based on your spec yourself, or get a developer to write them and review them yourself. Otherwise you will have to test everything manually, every time they deliver you new code.

But even then, your customer may encounter issues that you didn't test for.

My dad lost both hands and most of his forearms as a child. He has always preferred to use his own stumps as-is, rather than mucking about with prosthetics. But then he learnt to use his arms at an early age, and he was determined to do everything he could.

He can do practically everything you or I could do, except for things he simply can't reach or that require juggling to many things too rapidly. He has the neatest "handwriting" of anyone I know, he types by holding a pen, he can drive a car, develop software, and he's built a house extension. As an adult he's always been a productive member of society.

While you may develop the dexterity to use a prothethic. Don't discount the potential usefulness of your remaining limbs just as they are.

I'd say there's a non-zero risk of an IPv6 connection failing. When something breaks in IPv4, everyone notices and fixes it. But for IPv6, since hardly anyone is using it and applications should fail over, there's a good chance that a failure will go unnoticed.

This recent(ish) talk (video) has some interesting statistics on IPv4 exhaustion and IPv6 take up.

Which ISP & web host would turn on IPv6 support by default with that kind of end user delay?
