Reply to i need a favour: people who have been driving for less than five years, please answer two questions for me by neku

  1. Making sure you're aware of your surroundings at all times. Habitually checking mirrors, looking out your side windows, checking your blind spots, always signalling -- and doing this without thinking about it. Making sure it's part of the normal stuff you do as a driver without even noticing you're doing it.

  2. I consider myself to be one, but the vast majority of drivers consider themselves to be better than average drivers, so i kinda take that with a grain of salt :)

Good luck on your class I hope you pass!

To the extent that they are both memory managers i suppose; the way it works is very different seeming tho from what i saw.

MPS looks like a graph walking GC based, hierarchical pool system; this one is more just based on, it allocates a page of memory, hands you blocks out of that. When you free some memory, it marks those blocks back free.

The interesting thing about it is that it can compact your physical address space without having you have to update any of your pointers.

I think it's more analogous to TCmalloc or jemalloc than that in that it is much simpler seeming but i didn't look too deeply.
