Is anyone else having a problem with firefox where their extensions arbitrarily stop working, unless they go to the add-ons section, and disable and re-enable them?

Like, restarting firefox doesn't fix this. Only the add-ons page does.

FWIW I even pruned my add-ons a bit.

And if your advice is to switch browsers, just don't bother replying.

@JordiGH You don't need GR for accelerated motion, only if you're actually including gravity. Acceleration can be treated in special relativity using momentarily comoving inertial frames.

Final Fantasy I - the one where monks are the best
Final Fantasy II - The one with Cecil
Final Fantasy III - the one with Terra
Final Fantasy VII - the one with Clout
Final Fantasy X - There were two of these, also: HAHAHAHAHA
Final Fantasy XIII - There were three of these.
Final Fantasy XV - There's a car.

I have split days off next 2 weeks. Today is my day off. I have finished reading "The Middlesteins". I felt more real about their lives and relationships in this book. I enjoyed reading the part that the old man tried to find a new partner after leaving his sick wife. I also liked the Chinese man who got into relationship with the sick wife.

I will read other works by Jami Attenberg. I liked the way how she created characters with their back stories.

@JordiGH There was some really interesting use of this concept in Quake, where they specifically tried to optimize for pentium CPUs by deliberately alternating floating point and integer instructions. Kind of a crude early form of the kind of pipelining thing CPUs and compilers are better built to do now. (...also it ran poorly on anything that wasn't a Pentium.)

Michael Abrash wrote about it in his famous Black Book:

@JordiGH So, in the pipeline, when a result needed by an instruction isn't ready, (especially common when fetching from RAM), you have a "pipeline stall" and yes part of the CPU will do "nothing" while it waits:

https://en.wikipedia.org/wiki/Pipeline_stall

Though while one instruction is stalled, other instructions can keep going at the same time as long as they don't depend on its result (e.g. use the same register)

Compilers are pretty good at choosing the right registers/operations to maximize pipelining, too.

@JordiGH Checking through answers in this thread, I couldn't see anyone using the magic word "pipeline".

On modern CPUs generally it tries to do many things at once, by keeping all the various units inside the CPU occupied as much as it can. Think of how a floating point operation needs different circuitry than integer stuff... if you have them both in there, why not use them both at the same time? Or heck, what if you had two or three adders instead of just one?

Also an interesting interview by one of the organisers

In case I'm not the last one to hear about this, there's an online game expo this Saturday about games made by people of colour.

The schedule looks interesting, there's already a number of talks I'm thinking of attending. Lots of short talks too, which is a plus in my view, so you can quickly get an overview of a subject.
