Uhhhh.

Wow.

So, did you see there is a music genre called mulletcore.

Hm.

I'm guessing the mullet crowd is the target audience of the advert.

Circuit Cellar?
I'd like to see Memristor Cellar.

Anyway, the two-stage bootloader looked like something useful with base 4 code, I just read this issue, pretty good, considering I'm not an EE. (or even an ee)
This site has tons of free books. http://ebooks-share.blogspot.com

I am officially homebound in my attempt to become a Linux Guru. My beard is almost done, my diabetes is coming along nicely, and I have had the noodle dream.....just joking. sort of.

Do you realize that to get a decent job a hacker basically has to let the other (slow) team bust him and punish him--punish him for being better at thinking in different ways. So, if you need them to bust you, shouldn't it be a bust on the Big Dirty?

To the average white guy, this movie is way out of grasp. Stick to watching 'Ow, My Balls!' and 'Dancing With the Stars'

This movie is violent and sad and happy and fucked-up in so many ways all at the same time that I have seen it six times since Friday. My girlfriend refuses to watch it because she decided it was too much work to read subtitles. Ha! Her loss. It's been a long time since I got to be the conformist, and I have a feeling everyone who sees Slumdog Millionare are going to be as surprised as I was.

Even the soundtrack is unbelievably good. I wonder how many people watching this heard 'Paper Planes' by MIA and thought that T.I. got sampled. hehehe
Anyway.......credits seem to be rolling.

I may just start it again now.

Bash is so intuitive that you can just make shit up as you go and it still works.
Some of these autocommands I use, and some I just found out about screwing around 'researching'.

Automatic Command Completion

Use the TAB key and bash will attempt to complete the command for you automatically. You can use it to complete command (tool) names. You can also use it when working with the file−system, when changing directories, copying files et cetera.

There are also other lesser known ways to use automatic command completion (for example completing user names)

ESC−Y (Y: special character) Will attempt to complete the command name for you. If it fails it will either list the possible completions (if they exist). If there are none it will simply beep (and/or) flash the screen.

CTRL−X−Y (Y: special character) Lists the possible completions (it won't attempt to complete it for you) or beep if there are no possible completions.

Special−characters:

Use the following special characters combined with either ESC−Y or CTRL−X−Y , where Y is some special characters.

For example ESC−$ or CTRL−X−$ to complete an environment variable name.

◊ ~ (tilde) complete a user name
◊ @ (at sign) complete a machine name
◊ $ (dollars sign) complete an environment variable name
◊ ! (exclamation mark) a magic character for completing a
command name or a file name. The ! special character has the
same function as the TAB key. It works in some other
situations; for example when completing man page names.
