Comment Re:Upgrade your rsync! (Score 1) 227

Yeah I use rsync in cygwin to distribute from a Win7 desktop machine to both an external mybook sort of drive and a Linux machine with RAID array. When using the size/time/date matching method to a non-Windows machine it is important to use the --modify-window=1 flag recommended in the man page else the timestamps may fail to match resulting in more data transfer. I run it nightly from a scheduled task but it does not take very long to complete.

Damn Nagle. ;) Gamers have been hating buffers since modems. Dropped packets are not evil. Apps which require low latency but humble bandwidth should be able to interrupt the queue, but I can't think of a way that ISPs could really distinguish these apps reliably and it falls back to the problem of ISP choosing favorites. With latency and max bandwidth to an arbitrary host as unknown and varying, as well as the volume of traffic exchanged with the host, the empirical ramp-up/back off seems to be best for a single connection to get good bandwidth. Contention between high bandwidth transfer with less important latency needs and low bandwith transfer with important latency needs is not working well. Makes me think about profiling or tailoring TCP parameters for different connection types, people jumped through all sorts of hoops to try to tailor their stuff to low latency when dial-up was king.

I'm not sure that a perfect copy could be made in any case due to specific effects of the copying or hot-swapping process itself.

Say you have a process intended to snapshot a mind by capturing physical config of the brain. We cannot measure all of this without affecting the system as part of the measurement process. Recovering every detail (impossible) of every particle etc. requires subtly touching every particle etc. Even if you had a wonderful scanner that got a nearly perfect picture as minimally invasively as possible, it's quite likely that undergoing such a scan would be psychologically disturbing. Assuming the scan takes finite time at all, what do we get in the copy? The mind's contents just prior to being zapped with the scan? What it felt like being scanned? The mind that has memory of the scan just having been completed? I don't see any sort of perfect synchronous copy to really be possible or meaningful.

As far as the survivors would go, an original and copy might well recognize differences between themselves based upon differing views of "the divergence". :)

How the survivors (at least the copy) might act could be influenced by expectations programmed into the copying process itself if there were enough understanding of what was being copied. A surviving mind that was expected to operate with any significant changes in hardware might be in an ill place indeed without some modifications of physical expectations.
