Firefox 4 and Vimperator 3

firefox

I've been using Google Chrome's dev channel for the past year or so as my primary browser, but between some questionable aesthetic decisions and Chrome's tendency to segfault every hour or so for the last few dev releases, I decided that it's time to give up on the faster browser in exchange for the usable browser. Toward that end, I'm going back to Firefox. I hear that Firefox 4 is the next cool thing, so I set it up on my work machine (4.0b10pre, if you're interested). And, of course, since I am both a die-hard vim user and …

*nix Tip of the Day: Waiting in Scripts

Scripting is what makes Unix-like operating systems great. Every *nix, be it Linux, BSD, OS X, AIX, Solaris, or whatever other random distribution you can come up with, comes with a capable shell (or three) and a good set of basic utilities. Where a Windows administrator has to either fall to the horror that is Batch files, write code in a big, heavy programming language language, or submit to the terrible dominance of “management utilities”, a Unix system administrator has tons of the tools at his disposal to fix and automate things. I could talk about scripting forever (it is a substantial portion of my job), but today I'm just going to talk about one small facet: waiting for things to happen.

An iPad in San Francisco

iPad

So, I've been in San Francisco apartment-hunting for the past couple of days (I found a place!), and the only computers I brought with me are my iPad and my iPhone. It occurred to me that this might be a useful basis for a review, so enjoy. As a reminder, I have the 64GB model with 3G and WiFi.

In brief, I am extremely satisfied. I have been using the iPad to browse Craigslist, listen to music, keep up with my e-mail (including a community-l thread that made me long for the upcoming threaded mail view), and so on. It …

iPad 3G Unboxing

The universe smiles on me today: on the day that I finish all of my work for my undergraduate degree, my new iPad 3G appears. It's currently doing its initial sync (photo "optimization" takes ruddy forever, and I'm only synchronizing 3000 photos). For the time being, here are my unboxing photos.

dnsextd, TCP, and IPv6

Hello interested parties. dnsextd (in my git repository) now supports TCP. It was actually sort of an amusing bug. I guess the dnsextd code must date back to PowerPC, because it had an extra ntoh call which on little-endian systems would cause TCP requests to fail. It's fixed in the "tcp" branch of my git repository. In case you're curious as to how to get that repository, you would use the following:

% git clone //files.roguelazer.com/projects/mDNSResponder-214.git
% cd mDNSResponder-214
% git branch --track tcp origin/tcp
% git checkout tcp

Dynamic DNS: Part Two

Bonjour This post is a follow-up to Dynamic DNS

When last I left you, we had basic updateable DNS running and could update it from OS X. I've been a bit busy since then, but thanks to some prodding from @Loredo, I got back in and started looking at. What follows is the exciting story of how I got things up and running -- by the end of this post, you'll have access to a working copy of dnsextd for linux, and a client application that updates SRV and IP (A/AAAA) leases. Woo.
