A description of known problems in Satoshi Nakamoto's paper, "Bitcoin: A Peer-to-Peer Electronic Cash System", as well as notes on terminology changes and how Bitcoin's implementation differs from that described in the paper.
The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power.
| Well, I suppose its `safe' to release this, it seems everyone and their dog has | |
| it and apparantly (and to my surprise) it still works. | |
| The `smurf' attack is quite simple. It has a list of broadcast addresses which | |
| it stores into an array, and sends a spoofed icmp echo request to each of those | |
| addresses in series and starts again. The result is a devistating attack upon | |
| the spoofed ip with, depending on the amount of broadcast addresses used, | |
| many, many computers responding to the echo request. | |
| Before I continue may I first say that this code was a mistake. When it was |

| #Install ChromiumOS touchpad driver for linux chroot (crouton) on Acer C720P (Peppy) Chromebook. | |
| #This makes the touchpad behave and respond like it does in ChromeOS. | |
| #See: https://github.com/hugegreenbug/xf86-input-cmt/issues/6 | |
| #I posted a note about this script in: https://groups.google.com/forum/#!topic/crouton-central/claM9XZxsz0 | |
| #and https://github.com/dnschneid/crouton/wiki/Acer-C720-C720P#touchpad | |
| #After creating/installing this driver, look at: | |
