If this line is actually true:
"Therefore, the attempt to access the 21st value produced an out-of-bounds memory read beyond the end of the input data array and resulted in a system crash."


Several stages of inspection and testing were not properly undertaken. At the very least:
A code walk of the new code would have flagged a potential problem;
Running the segment of code in a sandbox and feeding it "defective" data;
and doing much the same one the "sensor" side to make sure the sensors cannot send more than 20 items in their output array.

Add to that, making sure that erroneous data is safely handled and flagged as such, not just take that data and either crash the system or produce wrong results.

All in all a couple of very simple steps could so easily prevented this system crash. (Does that ring a bell?)

Years ago, picked 20 because it was a huge number that never would be approached. Sounds about like Y2K and just two digits for the year. Or Unix End of Time.

As to tightly integrated - they wrote a kernel driver -- code that can't crash and must catch all its errors itself.

A new underground rail line is causing problems for hospitals over its route.

Why do electromagnetic train waves make MRI images inaccurate?

Following reports that sensitive medical equipment at Melbourne hospitals were being affected by trains in the city's new underground metro line, Premier Jacinta Allan was not surprised.

The Age newspaper obtained leaked documents revealing electromagnetic waves from the Metro Tunnel testing had been interfering with the MRI machines in Parkville's hospital precinct, which includes the Royal Melbourne Hospital and the Peter MacCallum Cancer Centre......
Some expensive Faraday cages will be needed.

Nah, just move the magnet next to the tunnel and trap the train against the wall.

I can't believe they did that. I did the MRI/EMF impact analysis for the California high-speed rail. We determined that we need to be at least 850 feet from any healthcare facility to avoid any such interference. We did adjust the route to make sure we avoided any hospitals.

I had a thought. Just imagine if the rail line was a maglev. I imagine the separation distance would have to be greater.

The really sad thing is that there's probably someone out there with way too much money that will buy one.

Want to own your own "dinosaur tree"?

Wollemi pine saplings to be auctioned off for 30th anniversary of species' discovery.

A handful of rare Wollemi pine saplings, propagated from a secret population in the Blue Mountains, are being auctioned off to mark 30 years since the species' discovery.

The pine's last wild community consists of just 46 adult and 43 juvenile trees in a secluded rainforest canyon in a World Heritage-listed area north-west of Sydney.

According to fossil records, the critically endangered "dinosaur tree" dates back more than 90 million years, and was presumed to have gone extinct around 2 million years ago, until a remnant grove was stumbled upon in 1994.

The auction is the first time saplings that are each genetically distinct will be released to the public.

Director of horticulture at the Botanic Gardens of Sydney, John Sieman, said the greater the difference in the trees' genetics, the better chance they had of survival.

"Those people who are purchasing into the auction, we hope have that passion like we do, for conserving plant species," he said.

"In a way, they become an extension of our conservation network.".......

Cheers.

This thief got more than he bargained for.

Camera footage has captured multiple angles of a citizen’s arrest in western Sydney which ended with a soaking wet alleged intruder and a stark warning from residents.

A neighbour has sent a warning to would-be thieves that his suburb is not to be messed with after a citizen’s arrest was captured on film.

The incident happened at 9pm in Guildford in western Sydney on Wednesday, and ended with an alleged burglar falling into a pool and being taken away by ambulance.

In the footage, neighbours can be seen confronting a man walking on the street.

“Hey brother. Who’s f***ing unit are you going into?” a neighbour can be heard saying on CCTV.

Two neighbours confront the man as other residents come out to have a look as the alleged thief tries to flee.

Footage from another CCTV camera shows him running through a backyard, but he falls into a swimming pool.

He pulls himself out but only takes a few steps on dry land before falling in a second time.

The alleged offender was then arrested by the neighbours before police and paramedics arrived.

The arrested man was taken to hospital.......
