Bike Rack Rack - My second meta bike rack project

Last year I upgraded my bike rack to the Thule T2 918XTR, which carries bikes tray style.
It's awesome, and works with bikes where frame geometry or size makes a frame carrier impossible.

The problem is that it is a 90# monstrosity when not mounted on a car, using up a ton of floor
space, and difficult to stand up vertically or hang.

My solution was to weld together a Bike Rack Rack. It is constructed of 6 4' 2x2 steel
sections, and 3 trailer hitch receivers, all welded together in a simple manner.

I got the Thule Rack for 4 bikes, be we only move around 3 bikes at a time, so that gave us
an extra tray, which I can use as a single bike rack on a car by just using a 2x2 insert into
the car hitch. This single tray can be seen on the left side of the image....mounted
higher on the Bike Rack Rack.

I can also move the single tray to a 1 1/2" hitch using a 2" -> 1 1/2" adapter so it
can be used on a car with only a 1 1/2" hitch receiver.

So now, all the bike racks, and 3 bikes can stand neatly and safely in a 5'x 6' space.

2012 OSI Network Fairness Model (Updated)

Back in 2008 I published my 2008 OSI Network Fairness Model. Given the SOPA and PIPA legislation now in consideration this model obviously needs to be updated!

The 2008 Fairness Model added an Enforcement Sub Layer into the existing 7 layer networking model. This sub-layer added new features to ensure that the proper authorities are informed of your activities, that your ISP's competitive objectives being met, that media companies are automatically compensated for content consumption, that litigation is automatically initiated and that anyone with a bad attitude towards this model is automatically subjected the model's filters.

Now with legislation getting behind enforcement on the Tubes we can beef that up. To keep things simple only two new sub-sub-layers are added.

New SOPA and PIPA enforcement sub-sub-layers:

  • 3aa: Automated DNS filtering and DNS seizure order generation
  • 3ab: Automated filing of criminal charges on both parties

I am quite certain all this is very easy to implement and will work correctly and not damage Internet security at all.

The sub layers now implement both civil and criminal legal apparatus, including internationally scoped actions. Finally the Internet will be safe for everyone.

bike trailer bike rack

I made this a while back. To allow my daughter to go on longer bike rides I got a bike trailer. Of course she would like to ride on the easy parts, so I added a bike rack to the bike trailer to carry her teeny bike. Its made with 1x1 ash, a couple of u-bolts, and a few nuts and bolts.

The bike on the rack is an 8" frame bike with rear suspension. Pretty amusing on a little kid's bike. It was a prototype bike we got at Bay Cycle in Whitby. The bike rack carries a 10" bike nicely too.
