....Nope. iPhone 3Gs are just as susceptible. The sooner that Apple realise that they've backed the wrong horse (as usual) and move their hardware to an OS that works, the sooner their massive losses in sales to Android phones will stop.

...and it took about an hour to circumvent the Apple patches. They really don't have a clue!

Your statistics must be straight from Microsoft - they bear no relation to reality! Why do 90 of the top 100 websites on the planet use Linux as their OS? Why do another 6 use BSD? Why do only 4 use Windows / IIS?

Linux is tested against attack much more rigorously and extensively than Windows ever could be - just by virtue of its predominance as a web server OS. MS just can't compete in secure computing (they don't really want to).

THERE IS MALWARE FOR MAC AND FOR LINUX BASED OSes

Not in the real world, there isn't. The only actual virus, trojan and malware infestations in the wild are on Windows machines. It's just another monopoly that MS have (and are welcome to!). Intelligent computer users don't use Windows.

Not that anyone else other than you has seen!

They're NOT "cameras" they're microwave radar units (like shop door openers). They're best used just for opening doors - they're usually crap on the road!

'No-one apart from JRA and our supplier knows which intersections have that system.'

Nonsense. The external "patch" antennas are a dead give-away!

No - see above. They're Microwave, Doppler-radar devices. If correctly aligned, they'll even detect bicycles.

They aren't "cameras" - they're Microwave Vehicle Detectors. They're Doppler-radar based detectors. That's all. No pictures involved - they work just like a shop door-opener!!

Why can't a scalable traffic system be designed and built with smart traffic lights that actually see and react to traffic?

They can. As a former signals engineer, I can tell you that "smart" signals have existed for the last 50 years. It's just that there's often little will to spend money on intelligent control. In the USA, 95% of traffic signal controllers run in "Fixed Time" mode, where they may as well be clockwork. Here in the UK, some local authorities actually have a clue, and (within the limits of their budgets) implement "Urban Traffic Control" using a centralised traffic analysis and timing modification systems. It's interesting (and informative) to see the differences in traffic flow with UTC active and inactive!

The stupidity of the SA authorities is amazing, though not unexpected - they kicked out all the competent engineers years ago! The people that remain there are the ones who bought themselves positions of authority and created spurious "qualifications" to try to justify themselves. They are a uniformly clueless bunch.

It's funny that they didn't lock their traffic signal controllers, they installed SIMs with full facilities, and they didn't spot the problem as soon as the first or second SIM went missing!!

The thieves would have identified the controllers with SIMs by the external aerials fitted to them!
