Printers present an interesting IoT example because they are far more powerful than other IoT devices, yet are not always considered real computers by most network administrators.

Not surprising one bit!.....the new Ricoh Multi-Function Print-Copy-Scan machines have an actual Android tablet that is the interface or "head" of the machine--a touch panel....so basically it is two CPU's--one for the touch panel controller and one for the Print Engine which is in the main body of the machine. Each has their own firmware updates!!!

I think that trusting any autodrive function to the point where the driver is watching a movie, instead of attentive and able to nearly instantly override is criminally insane. Even the more capable Google self driver with full LIDAR imaging and a simple layer of tactical prediction is not anywhere near operation without attentive operator IMHO. The driver of this vehicle was suicidally stupid. But that said, with all deference to my friends at Tesla, and those who own one, the autodrive function IS NOWHERE NEAR FUCKING READY TO BE ENTRUSTING YOUR LIFE TO. Please don't use it un-monitored, I don't need to lose any friends .

I do have some feedback for the folks at Tesla though that the marketing of this feature needs to be turned way down unless you plan on putting in an electroshock system that zaps inattentive drivers. The Tesla system is particularly lacking full depth long range high resolution depth mapping, such as Google and others achieve with lidar. And before any of these self drivers come anywhere near to acceptably safe for inattentive operators I would want multiple redundant depth mappers (sonar, lidar, and radar) as well as camera systems with optical pattern and shape recognition. They also need much deeper and a couple more layers of tactical and predictive logic than we have today in any system that we've seen documented to date to be anywhere near to safely supplanting operator attention and reaction time to override.

In this case of the operator and his family were watching a movie when the optical pattern match failed on the white truck and the car bounced off it into a roadside obstacle, it's reported - with the horrific detail that first responders and witnesses found the movie still playing at the fatal accident site. I'm concerned that this incident happened a few months ago and the alarm call took this long, Volvo has a team that rapidly investigates any fatal accident involving their vehicle brand and Tesla might be well served to emulate that and speed dissemination of this kind of important safety information - the Volvo team's efforts have yielded lots of important insight into vehicle safety (takeaway #1, secure your pets, cargo, and passengers, they are the most deadly thing in your vehicle, prone to fly about in a crash). I'm dead certain, pun intended, there are multitudes of corner cases, and unaccounted for situations waiting to bite anyone stupid enough to trust the welfare of their passengers and external road accident victims to an automated driving program unsupervised.

Also articles like this "Don't Freak Out" piece that lull operators of vehicles (probably the most dangerous activity the majority of people take part in regularly) into a false sense of complacency do us all a disservice.

Hmmm, would it be "criminally insane" to require politicians to be driven around in these cars -- stocked with lots of movies to watch?

First, some nice words from my friend Nick Hunter
"I generally don't like to take sides in an argument when I don't have a deep understanding of the specifics. But I feel like a few things need to be said.
The shootings of Alton Sterling and Philando Castile are utter tragedies. Even worse so that these were not exceptional cases in this country. My heart goes out to the African American community. I can't fathom how events like these must make you feel.
To say the least, I am upset.
We are caught in a vicious cycle of distrust, anger, fear, and hate as a nation, and it seems on the brink of exploding. The fact that we resort to violence so readily as a means of conflict resolution makes this all worse by an order of magnitude.
I have no real answer on how to fix it other than to call on all of us, as Americans and fellow human beings, to consider one another with greater empathy. Consider that we were all small children at some point, filled with a beautiful potential for kindness and curiosity, that we are all shaped by the events between then and now, and that the only way we break the cycle is by engaging with the "other side" and making a concerted effort to understand one another.
Drawing back into our respective tribes will only further fragment and divide us. We can't have real progress without changing the hearts and minds of those that would otherwise perpetuate the cycle of violence."

As I read the news this morning I am puzzled by my own response, because I was more upset by the attempted deletion/suppression of the Facebook live video showing the racist execution by a police officer of a black man who had done nothing wrong, acted correctly upon being stopped, and by all accounts was a pretty good man, in front of his wife and child. This upset me more than the eye for an eye violent idiocy that led angry black men to start sniping at police officers shooting eleven and killing four, and pushed the targeted police department to finally cross that line and send a remotely operated robot to blow up a barricaded sniper without a trial.

I guess a country that accepts an openly racist presidential candidate and blithely accepts 116 civilian casualties from political/military drone executions without trials on foreign soil, was inevitably bound to cross that line domestically with killer drones, so its shock was lesser. I think was more upset by the deliberate destruction and suppression of evidence of the police wrongdoing because it pointed out how instead of correcting the racism, it's condoned by deliberate attempted destruction of the evidence ("it's a technical glitch") and attempted suppression of its distribution (the folks who do social media filtering must be having a meltdown this morning) which just reinforces the implied acceptability of racist police executions instead of prosecuting them and those responsible for evidence suppression - the very system of justice needed to correct this is biased towards burying/encouraging the problem. As the military killing machines trickle out to law enforcement, executions without trial are seemingly accepted, and conditions for civil revolt increase - because if the watchmen are likely to shoot and execute you because of your dark skin regardless of whether you do right or wrong, you start to lose disincentives to legal conduct - I'd like to remind folks that as many black and dark skinned engineers (if not more) designed and built those military killing machines, and due to the demographics of your military, probably more dark skinned individuals are trained and certified on the operation of the increasing scales of devastation weapons systems. This is not a road you wish to transit. The bias that allows police to misbehave depending on race(or even misbehave at all), and tolerates racism must be reversed, or the conflict that results will be utter grief. Please. Have some empathy, for that baby that just watched their father killed, and every other person and race on the planet.

+Ken Barber Sorry, I had to go to work, and I see there's been a lot of discussion, but at this moment I'm only going to respond to your comment about "people like Bert Knabe." First, what I said:

Our country has a gaping wound that is only being picked at and allowed to fester. We have to find a way to heal it and people like +Ken Barber and Donald Trump are not helping.

That doesn't blame you or Trump for the problem, it just says you're not helping solve it. The festering wound I'm referring to goes back way beyond Lyndon Johnson. We can't do anything to change that past (or even the past of Lyndon Johnson - how is it his fault, btw?) but we can acknowledge it, and acknowledge the racism that exists today. If we won't even admit it still exists, how can we fix it?
