Why this is unlikely to affect the outcome of the MH370 search

If this really is a flaperon from MH370, and that remains to be confirmed, then it’s good news in a way because we could use wind and current data for the Indian ocean to determine where it might have gone into the water. That in turn could be used to update a probability map of where we think it most likely that MH370 went down by adjusting our prior probabilities in the Bayesian search strategy. In other words, all the information we have could be fruitfully integrated into our search strategy.

Well… perhaps it could, if the ATSB were actually applying a Bayesian search strategy, but apparently they’re not. So we’re unlikely to get the most out of this piece of evidence. The only upside that I see to this is that it should shutdown most of the conspiracy nut jobs who reckoned MH370 had been spirited away to North Korea or some such. :)

We must contemplate some extremely unpleasant possibilities, just because we want to avoid them.

A big shout out to the Chrysler-Jeep control systems design team, it turns out that flat and un-partitioned architectures are not so secure, and maybe not that safe, after security experts Charlie Miller and Chris Valasek demonstrated the ability to remotely take over a Jeep via the internet and steer it into a ditch.

Chrysler’s patched the Sprint/UConnect vulnerability, and subsequently issued a recall notice for 1.4 million vehicles which requires owners to download a car security patch onto a USB stick then plug it into their car to update the firmware. Well done Chrysler-Jeep guys you win this years Toyota Spaghetti Monster prize* for outstanding contributions to embedded systems design.

More woes for OPM, and pause for thought for the proponents of centralized government data stores. If you build it they will come…and steal it.

For no other reason than to answer the rhetorical question. Feel free to share.

How?

Hannibal ante portas!

A recent article in Wired discloses how hospital drug pumps can be hacked and the firmware controlling them modified at will. Although in theory the comms module and motherboard should be separated by an air gap, in practice there’s a serial link cunningly installed to allow firmware to be updated via the interwebz.

As the Romans found, once you’ve built a road that a legion can march down it’s entirely possible for Hannibal and his elephants to march right up it. Thus proving once again, if proof be needed, that there’s nothing really new under the sun. In a similar vein we probably won’t see any real reform in this area until someone is actually killed or injured.

This has been another Internet of Things moment of zen.
