AI Class Playlists - O! Mr Speaker! →
Lil’ reference for anyone doing the Stanford AI class… It’s a collection of playlists for each unit, so you can grab them with something like youtube-dl (I use the command youtube-dl -w -t -f 18 http://playlisturl. I didn’t check what those flags do, but it says “wtf”, and that’s all that matters).
The problem with the make included with MozillaBuild is that it doesn’t take advantage of multiple processor cores on Windows. So even if you have a crazy-powerful 8-core machine, when you just use the vanilla “make -f client.mk” command, you’re only going to be using one of your cores. Enter pymake. Pymake is a Mozilla-maintained mostly-compatible implementation of make in Python. The advantage?...

Kahneman and Tversky, the guys who first really began to probe human cognitive errors, found in their research that there was a systematic human tendency to either under or overestimate the expected value of a reward that varied as a function of time. I’ll give you an example. Do you want a dollar today, or 10 dollars in a year? Most people will say a dollar today. How about a dollar today,...

The level a programmer works at (say, Emacs) is too abstract to support a business. Developers working at the developer abstraction layer need an implementation layer — an organization that takes their code and turns it into products. Dolly Parton, working at the “singing a nice song” layer, needs a huge implementation layer too, to make the records and book the concert halls and...

The 27-point agenda covered every phase of the offering. Gates said the company was contemplating a $40-million deal. Microsoft would raise $30 million by selling two million shares at an assumed price of around $15. Existing shareholders, bound by Gates’s informal rule that nobody should unload more than 10% of his holdings, would collect the other $10 million for 600,000 or so shares. The...
In bash, use Ctrl-R to search through command history.
In bash, use Ctrl-W to kill the last word, and Ctrl-U to kill the line. See man readline for default keybindings in bash. There are a lot. For example Alt-. cycles through prevous arguments, and Alt-* expands a glob.

Commands I use regularly instead of using ifconfig:
# link up/down ip link set dev eth0 up|down
# add a new address ip addr add dev eth0 172.16.43.124/24
# to clear all IP addresses from eth0 ip addr flush dev eth0
# delete an address ip addr del dev eth0 172.16.43.124/24
# add default route ip route add default via 172.16.43.254
