Installing the Brother DCP-7030 in Arch Linux

Running Arch Linux I had to create the following udev rule in
/etc/udev/rules.d/10-cups-usb.rules
in order for the printer to be recognized.


ATTR{idVendor}=="04f9", ATTR{idProduct}=="01ea", MODE:="0664", GROUP:="lp", ENV{libsane_matched}:="yes"


Then I was able to use the driver in the AUR to install it in CUPS.

This entry in the Arch Forum helped me figure it out.

Install Ruby 1.8.7-p352 on Arch Linux

I'm returning to Arch Linux for my trusty laptop. After installing RVM and all of the requirements listed in the notes page, I would get compilation errors when trying to install ruby 1.8.7-p352.


callback.func:78:33: error: expected ')' before '(' token
callback.func:79:3: warning: data definition has no type or storage class [enabled by default]
callback.func:79:24: error: 'proc' undeclared here (not in a function)

callback.func:79:45: error: 'argv' undeclared here (not in a function)
callback.func:82:1: error: expected identifier or '(' before '}' token


I was able to find a patch in the AUR version of ruby that fixed the problem.

A little VIM tweak to make the world go round

...or at least make me stop screaming at my computer. Adding

set vb t_vb=


to my .vimrc and .gvimrc files made all the visual (and audio) bells stop going off. When I would hold down the J or K keys and scroll away I would hit the end sooner than I realized and by the time I lifted my finger from the key I was forced to watch my editor flicker for untold eons of time before I could keep working.

Why?

I can see where I am.

I'm sorry I don't have computer-like reflexes.

Please just let me type!!
