If 2), then it was deliberate, and the tinfoil-hat crowd is right for once.
Well, it would be one very inefficient way of introducing a backdoor. The custom allocator stuff in OpenSSL is very old, but the heartbleed bug is quite recent, so someone would have had to plant a backdoor-seed if you will and then wait for many years for that tree to grow fruits. Could be done, but it doesn't sound likely.
The control system in my car reacts to bumps in the road, and turns the beams in the direction the car is turning.
This is what car manufacturers claim, but it's nowhere near true. The typical slewing time for the optics looks to be about 0.5 seconds from "standard" to "dipped", and that's way too slow for reacting to bumps/potholes when you're going faster than 30. I regularly get blinded by Audis, BMWs and Volvos with factory HIDs, but Mitsubishi seems to be worst. It could perhaps be that they are just worst at controlling chromatic abberations (since blue light blinds you more).
Really? To what end?
Well, why not? I found my right-hand little finger was cramping often. Coul be 'cause I use an "ergonomic" keyboard, which is quite good except the slightly bad position of the BackSpace key.
I see you've bound it to the Compose Key. That's utterly useless to me, since I very rarely write non-ascii characters (with the exception of æøå, and those I have dedicated keys for). When I want to write greek/fraktur/whatever, I write
$\alpha \to \infty \implies \sum_0^{\infty} n = -\frac{1}{12}$ etc. and then have the rendering engine (LaTeX) take care of it.
Customers are frequently wrong, and sometimes their actions are outright hostile.
Quite. I find this page to be a fun insight into the world of stupid customers.
If you're not careful, you're going to catch something.
