Figured out what I wanted for dinner and realized that we might not have it, so I stopped off at QFC on the way home. Picked up pork, cream, and a beer that looked interesting. Cashier didn't card me.
Why on earth do cashiers card me so rarely? I don't get it.
It's interesting that data buses seem to be a dying technology. S-ATA is clobbering the old hard drive bus (and isn't someone wokring on a point-to-point SCSI system also?), PCI Express is taking care of the old PCI bus, and USB is . . . just sort of filling a hole. Ethernet slaughtered its competitors long ago. Everyone's going point-to-point now. Theory as to why - chips are getting cheap enough to make central hubs extremely easy to implement with only simple logic on whatever's connected to the hub. Sort of a client-server setup - they're so successful everywhere else, why not in hardware?
I can't think of anything in the Computer of the Future (about two years from now) that will be a shared bus, actually . . .
Other interesting things - everything's going serial, not parallel. Chips are so cheap that you can handle an ultrahighspeed serial connection, but parallel connections are wider and have interference problems.
at times like this, i would not give up this gift for anything.
it's like . . . it's like dancing on a million oceans. it's like flying through a hurricane, and seeing every last temperature change and pressure change and breath of wind. it's like standing at the nexus of all the information in the universe and seeing, before it even gets to you, how it will all go together.
and you just grab the threads of execution, the datapaths themselves, and you pull and mold them, streams of actinic blue blasting through mental fingers.
the code isn't what's important. the code is just structure. a rock here to divert, then reinforce the far bank . . . what's important is the flow, the raw data.
sometimes you can find the crux.
