Notifications with Irssi in Screen

November 13th, 2011 2 comments

One of the biggest problems about running irssi in a terminal in screen is that there aren’t any notifications by default if you are mentioned, or if there is activity in a channel. By running these commands, you will be able to get these notifications. They can be tailored based on the notifications that you want.

/set beep_msg_level CRAP MSGS PUBLIC NOTICES SNOTES CTCPS ACTIONS JOINS PARTS QUITS KICKS MODES TOPICS WALLOPS INVITES NICKS DCC DCCMSGS CLIENTNOTICE CLIENTCRAP CLIENTERROR 
/set beep_when_window_active ON 
/set beep_when_away ON 
/set bell_beeps ON

I am currently running ArchLinux (x86_64).

Wireless Networking: Using a Cisco/Linksys WUSB54GC on Gentoo

November 13th, 2011 1 comment

We live in an old house, which has the unfortunate side-effect of lacking a wired network of any kind. All of our machines connect to a wireless network, and my desktop is no exception. I’ve got an old WUSB54GC wireless stick that was manufactured some time in 2007. In computer years, this is way old hardware. But with a bit of work, I managed to get it working with my Gentoo install.

This bitch is old... but it works

I started out by installing the NetworkManager applet with a tutorial on the Gentoo Wiki. This was a straightforward process, and after a restart, the applet icon appeared in the top right corner of my screen. If you left-click on the icon, it drops down a menu that lists your wireless interfaces. Under the Wireless Networks heading, it said that it was missing the firmware necessary to talk to my hardware.

The next step was to look around the net and figure out the firmware/kernel module combination that supports this stick. I found my answer over at the SerialMonkey project, which is run by a group that took on maintenance of older Ralink firmware after the company of the same name dropped support. According to the SerialMonkey hardware guide, my stick (or at least a very similar stick called the WUSB54GR) works with the rt73usb kernel module and related firmware.

This known, there are two methods of proceeding. Those running older kernels may need to manually compile the necessary packages using instructions similar to these, from the Arch Linux project. For more modern kernels, the Gentoo project provides a Wiki entry detailing the necessary steps.

After following the steps in the Gentoo Wiki entry, I restarted my system, and now have full wireless support. Genius!

Can you install Gnome3 on Gentoo?

November 13th, 2011 1 comment

So my base Gentoo installation came with Gnome 2.3, which while solid, lacks a lot of the prettiness of Gnome’s latest 3.2 release. I thought that I might like to enjoy some of that beauty, so I attempted to upgrade. Because Gnome 3.2 isn’t in the main portage tree yet, I found a tutorial that purported to walk me through the upgrade process using an overlay, which is kind of like a testing branch that you can merge into the main portage tree in order to get unsupported software.

Since the tutorial that I linked above is pretty self-explanatory, I won’t repeat the steps here. There’s also the little fact that the tutorial didn’t work worth a damn…

Problem 1: Masked Packages

#required by dev-libs/folks-9999, 
required by gnome-base/gnome-shell-3.2.1-r1, 
required by gnome-base/gdm-3.2.1.1-r1[gnome-shell], 
required by gnome-base/gnome-2.32.1-r1, 
required by @selected, 
required by @world (argument)
>=dev-libs/libgee-0.6.2.1:0 introspection
#required by gnome-extra/sushi-0.2.1, 
required by gnome-base/nautilus-3.2.1[previewer], 
required by app-cdr/brasero-3.2.0-r1[nautilus], 
required by media-sound/sound-juicer-2.99.0_pre20111001, 
required by gnome-base/gnome-2.32.1-r1, 
required by @selected, 
required by @world (argument)
>=media-libs/clutter-gtk-1.0.4 introspection

This one is pretty simple to fix: you can add the lines >=dev-libs/libgee-0.6.2.1:0 introspection and >=media-libs/clutter-gtk-1.0.4 introspection to the file /etc/portage/package.accept_keywords, or you can run emerge -avuDN world –autounmask-write to get around these autounmask behaviour issues

Problem 2: Permissions

--------------------------- ACCESS VIOLATION SUMMARY ---------------------------
LOG FILE "/var/log/sandbox/sandbox-3222.log"

VERSION 1.0
FORMAT: F - Function called
FORMAT: S - Access Status
FORMAT: P - Path as passed to function
FORMAT: A - Absolute Path (not canonical)
FORMAT: R - Canonical Path
FORMAT: C - Command Line

F: mkdir
S: deny
P: /root/.local/share/webkit
A: /root/.local/share/webkit
R: /root/.local/share/webkit
C: ./epiphany --introspect-dump=
/var/tmp/portage/www-client/epiphany-3.0.4/temp/tmp-introspectSfeqBO/functions.txt,
/var/tmp/portage/www-client/epiphany-3.0.4/temp/tmp-introspectSfeqBO/dump.xml
--------------------------------------------------------------------------------

This one totally confused me. If I’m reading it correctly, the install script lacks the permissions necessary to write to the path /root.local/share/webkit/. The odd part of this is that the script is running as the root user, so this simple shouldn’t happen. I was able to give it the permissions that it needed by running chmod 777 /root/.local/share/webkit/, but I had to start the install process all over again, and it just failed with a similar error the first time that it attempted to write a file to that directory. What the fuck?

At 10pm at night, I couldn’t be bothered to find a fix for this… I used the tutorial’s instructions to roll back the changes, and I’ll try again later if I’m feeling motivated. In the mean time, if you know how to fix this process, I’d love to hear about it.
