BEZOAR
It's Calculus, furball!
A Calculus is a mineral Bezoar[^], a Furball is a organic Bezoar[^] called a Trichobezoar.
And I'm up tomorrow!

All jabbed up ?

Yep! Pfizer this time, to go with the AstraZeneca last time.
Hopefully no nasties from this one, but I've planned a "slob day" for tomorrow just in case.

I've had Pfizer three times with no side effects at all - and I had my first ever flu jab at the same time as the booster - we're becoming a nation of narcos

According to the nurse today, the side effects generally happen in the "super fit", so we know which side of that equation you fall!
I just looked down at myself when she said that and raised an eyebrow Spock stylee.

I've never been described as super or fit ! never mind super fit

Same mix as me, but I was somewhat dodgy for a couple of days after the booster. And definitely not super fit ...
Good luck!

It's Calculus, furball! (6)
Sorry it's early, but I'm booked for a booster jab and it's an 80 mile round trip ... this is not a part of the clue or related in any way to the solution.

If an octopus lose it's foot, is it still called Octopus?

Humans are bipeds. If a human loses a foot, does he/she stop being a biped?

If the foot is simply injured but becomes septic, s/he'd be a septopus. Until it had to be amputated, when it would become just a septo.

What if it lost two legs, would it be a sexopus or a hexopus?

As much as it could become a Centipede.

Actually, they regrow. So yes, it's still an octopus.

A big one is not using synchronization primitives when running multithreaded code.
Even with multiple cores, you can time your code such that if you're careful, since everything operates at fixed latencies you don't need to synchronize.
For example, if you're rending a frame on a separate thread than you're drawing it, you are a okay, as long as you're always rendering *ahead* of where you are drawing. The schedulers on these devices are very simple, so you can actually get something like interlocked execution even across cores. Interrupts interfere with this, but in some situations, you don't need to worry about that.
I'm in principle okay with this, because it saves CPU and thus power, but OMG is it nasty.
I just spent some time retooling someone else's code to be single threaded because I was getting heap corruption and they weren't using synchronization primitives. I thought that was why. Nope. Something else is going on. It's not crashing or leaking (as best as I can tell without a debugger) though. It's only even reporting because of some memory guards that wrap allocations. This is what made me think of this.

Yes, it's nasty, but synchronization primitives can add a lot of overhead to a task, and make the task non-restartable. For example, take the case where a thread in the task takes ownership of a mutex then crashes. How do you know what the state of the mutex should be? You can possibly detect the crashed thread, but restoring the task to a consistent state without restarting from the beginning is much more difficult.
(I'm not going to do more than mention deadlocks, livelocks, priority inversions, convoying, and all of the other issues that can occur with lock-based multithreading. Even where fixes are possible, many small processors simply don't have the horsepower to handle all of these issues.)

Yeah, that's why I said I'm okay with not using them (regardless of how ugly it is to me)
It's just ... the "timing" thing doesn't inspire confidence in me. I'm used to traditional OS's where you simply can't do that.
