Script to set date/time of macbook without a battery

Copy the launch daemon file named com.startup.script.plist in /Library/LaunchDaemons. Then set the permissions for it

sudo chmod +x /Library/LaunchDaemons/com.startup.script.plist
sudo chown root:wheel /Library/LaunchDaemons/com.startup.script.plist

Next copy the shell script updatetime.sh in /usr/local/bin/. Make it executable with sudo chmod +x /usr/local/bin/updatetime.sh and owned by root:wheel with sudo chown root:wheel /usr/local/bin/updatetime.sh.

Enable and launch the Daemon with:

PCI-e bus bandwidth calculation

How PCI-e bandwidth and actual true data bandwidth can be calculated.

PCI-e 1.x uses an 8/10b encoding scheme, so to send 8 bits of data, 10 bits of encoded data must be transfered. 2 of those bits are there as error checking and correction bits to account for interference which is very common on fast buses. SATA btw also uses 8b/10b encoding, you loose 20% of bandwidth (1-8/10) to get the data across.

PCI-e 1.0 is clocked at 2.5Ghz, it sends 1 bit per clock cycle and each lane corresponds to a 1 bit bi-directional serial channel. Which is kind of neat since here 'Gigatransfers' indicate 1 bit transfered for every clock cycle. This should immediately tell us that unlike FSB which transfers multiple bts per cycle in a parallel fashion, PCI-e is serial, since we are sequentially throwing 1 bit of data per cycle onto the bus and it takes multiple cycles to send a full byte. While on a parallel bus multiple bytes can be sent per cycle.
