The following was a news article that I intended to record and have included in this week’s WIA National News service, however I had problems cutting it down to the 1:30 required. So, I’ve put in additional information that there wasn’t time for, and I intend to put in a short piece for next week’s [...]

A thought just occurred to me… With addressing in IPv6, there’s enough addresses to cover every square metre of the earth’s surface with something like 100 addresses or so.  Not sure if a standard exists for mapping geographic co-ordinates to addresses, but one just occurred to me that I might try some day. The Maidenhead [...]

Well, I’m not sure where to ask this, I did ask on the netdev mailing list and while I don’t think it’ll get ignored indefinitely, I’m not sure that was the right place.  A stab in the dark if you will.  In the hope of netting more answers though, I cast this query into the [...]

Well, I won’t say much but point-to-point and point-to-multipoint does not have to be short-range or rely on centralised infrastructure. People have been using a means of such communication for over 100 years, which allows for ad-hoc, distributed communications. Yes, it prohibits the use of encryption, but that doesn’t prevent us from using it as [...]

Yesterday was great. A lot of interesting discussion on Ardunio and the business of Open Source, particularly the commercial implications of the GPL. Well worth seeing. Today has been good so far too. Been in N515 listening to the parallel computing talks, and it has been very interactive as well. Whilst listening, I’ve set myself [...]

I picked up a few new toys recently.  I’ve been looking around for a small microcontroller based device to act as a combined remote face / DTMF generator for my FT897D.  The idea is that this device could interface with the FT897D via its CAT port, and allow me to adjust the frequency and mode, [...]

32-bit Gentoo/MIPS stages for both big and little endian systems are now available for MIPS-I, MIPS-III and MIPS-IV.  For now I’ve got these on my devspace, but I hope to get some of them out to mirrors as soon as possible.  I’d appreciate any feedback on this release. http://dev.gentoo.org/~redhatter/mips/sgi/stages/ — Big-endian systems http://dev.gentoo.org/~redhatter/mips/cobalt/stages/ — Little-endian [...]

I stumbled upon this looking up information on magnetic receiving loops.  Content is below, with my comments added. 1. When you look at a full moon and wonder how much antenna gain you would need. 2. When a friend gets a ride from you and remarks that you have a lot of CBs in your [...]

Hi all, I’m in the process of registering for LCA2011… since it’s in my home town, I figure I may as well show up. This will be the first LCA that I’ve attended, last one I was looking at going to was the one in Sydney a few years back … however at the time [...]

Hi all, This year I will be activating the Robertson Scout Den as part of this year’s JOTA. I’ll be working as a one-man band at least on the Saturday, working under my personal callsign of VK4MSL. Bands planned are: 80m 40m 20m 2m I can also do 15m, 10m, 6m and 70cm and may [...]
