When storms tire of swift yet futile rage I find myself standing in her shelter with peace & warmth unthinkable. The more I have to lose the more I’ve gained. Fear will not shackle me for she has set me free. Two singers, a single song, an ode to joy, hope and omnipotence of youth. Oscillating and undulating til they reach their inexorable damburst of resonant rhyme. Each molecule stirring in sympathy with touching, tingling, tangled souls. When the heart speaks the mind finds it indecent to object. When the soul sings the mind hums in blissful harmony, free at last… free at last…

It’s a conspiracy your honour
Ever been snapped by one of those pesky gatso cameras driving a little on the high side (above) of the limit. I spotted this article on the web and decided to do a little bit of research into the worldwide attitudes to speed cameras & whether such a defence would be acceptable here. The answer seems to be that in many of the countries where speed cameras are deployed to discourage speeding they are not admissible as court evidence. The reason being that the cameras are operated by semi-state or private organisations without the direct involvement of the police where private individuals and organisations are financially rewarded based on the number of infringements. In California, for example, the practice is deemed “unreliable” by the state superior court on this basis. The situation is the same in Colorado. In the US there is also the issue of correct identification of the driver. In California the cameras are required to produce a recognisable picture of the driver’s face for identification purposes. As far as I know, this is the case in Ireland where vehicle owners are asked to provide the name and address of the vehicle’s driver at the time the picture was taken.
As leading Internet security expert Bruce Schneier points out it’s true that MD5 is broken but very likely that the motorist in the australian case was guilty. However, theoretical security is important when the legal system assumes innocence before guilt and also places a burden of proof upon the prosecution.
So I guess the question you’re all wondering is whether the Irish garda use MD5 in a similiar way for non-repudiation purposes or whether the cameras are operated by a semi-state or private organisation on cash-per-infringement basis. Well AFAIK the cameras are installed and operated by Serco and Pulse uses MD5 checksums in places. I’m going to do some digging here but it does have fascinating and wide-ranging implications.

I’m neither advocating speeding nor castigating cameras but the following statistics are telling. In the UK cameras deployed in accident hotspots tend to reduce the number of accidents and fatalities by 30-40%. However, cameras tend to increase the ratio of fatalities to injuries wherever they’re deployed. Many of these fatalities are due to pile-ups caused by offending motorists quickly slowing down before cameras. There are a number of theories explaining these statistics.
- Some believe that cameras are distracting causing drivers to pay more attention to the speedometer rather than the road. Many studies have backed this up.
- Many serially irresponsible drivers slow down just before the cameras and immediately speed up again once past them, increasingly the likelihood of an accident during braking & while they try to make up lost time.
Finding value in rip-off Ireland
While watching the last in the series of Rip-off Ireland a thought occured to me about the industry that I know best, Information Technology. I’ve paid plumbers and electricians around 60 euro/hour to fix problems during normal working hours. Assuming a dilligent independent electrician working at these rates for 8 hours a day, 5 days a week, 42 weeks a year (holidays are vital to recharge the batteries) we get yearly earnings of over 100,000 euro. However, I never checked to see that the electrician who came around wasn’t an apprentice charging a a steep rate while remaining on a relatively modest salary. I just wanted my wires uncrossed 🙂. I must admit though, I did feel slightly ripped-off. As a software developer and web designer I meet the same customers who pay over 80 euro an hour to the plumber to come in and fix a leak late at night. However, the big difference is that they think they have some appreciation for what the plumber or electrician does whereas IT is a mystery. Even in this rip-off republic IT is often available for FREE!!! If that sounds too good to be true it’s because it is.
The sound of falling water
I’ve filed this posting under art as the best architecture is. In the words of a master “The mother art is architecture. Without an architecture of our own we have no soul of our own civilization”
The master in question being “America’s Architect”, Frank Lloyd Wright. FLW was born in 1867 and throughout a career spanning around 60 years he developed and refined the concept of organic architecture.
In his own words
“I would like to have a free architecture. Architecture that belonged where you see it standing—and is a grace to the landscape instead of a disgrace.”
Truthfully I would have loved to become an architect but I doubt my skills lie in that direction. The engineer in me is fascinated by the compelling mixture of elegant form and function througnout Frank Lloyd Wright’s best works. The most famous of which is Fallingwater. Constructed for Mr. and Mrs. E.J. Kaufmann senior at Mill Run, Pennsylvania, which was designed according to Wright’s desire to place the occupants close to the natural surroundings, with a stream running under part of the building. The construction is a series of cantilevered balconies and terraces, using limestone for all verticals and concrete for the horizontals. The cost of this architectural masterpiece was $155,000, a pricely sum in 1939. This included the architect’s fee of $80,000. In practical terms we can assume that adjusted for inflation the total cost was over 3 million dollars in today’s money. Kaufmann’s own engineers argued that the design was not sound. They were overruled by Wright, but secretly added extra steel to the horizontal concrete elements. I’ve recently found a fantastic site which enables people to navigate through Failling Water.
