Ubuntu 10.4 (Lucid Lynx) and Broadcom BCM4312

words by Brian Racer

This is basically just a repost of the same issue I had when Karmic Koala launched

Ubuntu 10.4 (Lucid Lynx) launched today and I figured it was time to do an install from scratch onto my Dell D830 Latitude laptop. Everything went quite smoothly but when it started up I noticed two issues:

Problem 1: No wireless

I know the Broadcom card inside the laptop isn’t the greatest, but the last two Ubuntu releases it has worked out of the box. The following command enabled the card after a reboot:

sudo apt-get install bcmwl-kernel-source

Problem 2: Really slow DNS lookups (because of IPV6)

As documented on Launchpad, there still doesn’t seem to be an official fix. Strangely disabling IPV6 in /etc/sysctl.conf didn’t solve anything, however disabling it in Firefox at least fixes the issue in the browser. Just type about:config in the address bar, and set network.dns.disableIPv6 to false.

Vim for Rails Developers Screencast

words by Brian Racer

Ben Orenstein was kind enough to send me a review copy of his Vim for Rails Developers screencast. Vim is pretty much the only text editor I have used for a few years now and I consider myself a fairly experienced user. This screencast showed me some useful new tips that I have been able to integrate into my daily workflow.

Much of the screencast focuses on the excellent rails.vim plugin, primarily using it to move around your project in incredibly efficient ways. He also covers snipMate, ctags, and searching with ack. I found his advice on using ctags quite useful for jumping around the rails source code.

Ben is well spoken and well paced, and I hope to see more screencasts from him(especially ones focusing on vim). rails.vim in particular has much more functionality to offer that I would love to see covered. If you enjoy the visual/audible style of learning be sure to also checkout vimcasts.org for more vim related screencasts.

This screencast probably best for late-beginner to moderately skilled vim users, but even advanced users will probably learn a new technique or two. It might be a bit overwhelming if you are incredibly new to vim as it’s focus is on usage and not getting things setup or configured.

Overall I feel if you are looking to get serious with vim the $9 will quickly pay for itself.
