Hacking Traffic Lights

A University of Michigan study led by J Alex Halderman has revealed that the nation’s traffic control system is laughably easy to take over.

The study said all that was needed was a laptop computer with a wireless card that could communicate at the same frequency used by the traffic lights, and the systems passwords. It was noted that the passwords and usernames in use were often the default ones.

Teachers Skip School More

A report by SFGate, has revealed that teachers in the San Francisco Unified School District skip are absent about 11 times a school year which is about five days more than a typical student.

SFGate says that the San Francisco teacher absentee rate is “even a smidge below average” compared to other large urban districts

It said that in non-teaching jobs — which should be noted go for 12 months and not just nine — the absentee rate is about four days per year.

If there is no penalty for failing to do one’s job well those having said jobs are far less less likely to do their jobs well.

Parents need the power to fire teachers and even entire schools. Vouchers will give them the power. The biggest opponents of vouchers are bad teachers and those they pay to represent them to legislators.
