http://www.wand.net.nz/~smr26/wordpress Hardly blogging at all since 2005 Wed, 22 Jul 2009 10:16:20 +0000 http://backend.userland.com/rss092 en So yesterday's post to madwifi-devel generated a few interesting responses, both on and off list. Derek Smithies suggested that the timestamp may not actually be for the previous packet, but for the end of the current packet. After looking into this today I realised that I had made a mistake while ... http://www.wand.net.nz/~smr26/wordpress/2009/07/22/a-closer-look-at-madwifis-timestamps/ I've been using (and occasionally hacking on) MadWiFi for several years now as part of my Ph.D research. It amazes me that after all this time we can still manage to find pretty severe bugs in the code. Today I posted a message to the madwifi-devel list detailing how Jamie and ... http://www.wand.net.nz/~smr26/wordpress/2009/07/21/the-problem-with-hardware/ For reasons I can't quite comprehend, several people have asked me over the last year or so to put up links to papers I've written during the course of my studies. These people are probably crazy. Seriously. Who really wants to read academic papers unless they really really have to? ... http://www.wand.net.nz/~smr26/wordpress/2009/02/10/crazy-people/ Turns out calculating elapsed times in Mac OS X is a pain. Why not just use gettimeofday(2)? If you're trying to calculate a time period between two events, you should be able to call gettimeofday(2) before and after, subtract the results, and you'd have an elapsed time, right? Well, almost ... http://www.wand.net.nz/~smr26/wordpress/2009/01/19/monotonic-time-in-mac-os-x/ The goal of this article is to document the process of setting up a basic KVM instance the hard way. That is, without using GUI tools, magic scripts, VNC'd installers, etc. Pretty much all of the KVM guides I've seen assume you're sitting at the physical box you're deploying the VMs ... http://www.wand.net.nz/~smr26/wordpress/2008/08/28/kvm-the-hard-way/ A few days ago I received my copy of "Ghosts" in the mail. I paid $10USD about a month ago and got the FLACs that day and have been listening to them ever since. Having the physical CDs now is a nice bonus - in fact, I haven't even ... http://www.wand.net.nz/~smr26/wordpress/2008/05/09/a-great-time-to-be-a-nine-inch-nails-fan/ Changes since radiotap-0.2: Name changed to libradiotap Now uses the GNU build system, creates both shared and static libraries Removed ieee80211_radiotap.h and folded the appropriate definitions into libradiotap.h Removed the IEEE80211_ prefix from the radiotap field constants radiotap_has_field() is now a static inline function Fixes for big-endian, tested on a ... http://www.wand.net.nz/~smr26/wordpress/2007/11/03/libradiotap-100/ On the weekend Emily and I decided that we needed to do more outdoorsy stuff, so we went and found a nice little walk on Mt. Pirongia, just out of Hamilton. We did the "Mangakara Nature Walk", which is a loop through some native bush and crosses the Mangakara stream. ... http://www.wand.net.nz/~smr26/wordpress/2007/10/29/outdoorsy-stuff/ Leopard now comes with a built-in SSH agent. The really nice thing about it is that it integrates with your user's Keychain. So, the first time you try to unlock your SSH key a dialog will appear asking you for its password along with an option to save that password ... http://www.wand.net.nz/~smr26/wordpress/2007/10/28/mac-os-x-leopard-built-in-ssh-agent/ I installed Leopard last night and as I was browsing my local network I noticed something kinda funny... apparently this is what a Windows PC looks like: http://www.wand.net.nz/~smr26/wordpress/2007/10/27/mac-os-x-leopard-easter-egg/
