Are you filtering for things like ESC j n that is an epson reverse linefeed. It realy was not that hard to get a general purpose line printer to spit back up and overprint with random strings.
It depends on how long of a loss of signal, a few ms sure a few seconds sure, get to 30 seconds and well you have a problem. And thats assuming that it's a missed poll. Polling a battery powered devices is a battery trade off. Mind you the zigbee wireless is a hell of a lot more secure than what ADT is putting in for wireless. Think remotes that can disarm the system without even rolling key aka 1980's garage door opener.
Lets see I already have on IoT radio in the ISM band, another in the 2,.4ghz, one at 345mhz, some sensors running a send only at 433mhz, and yet another that can run in 433/868/915MHz then add in 802..11ac in 2.4 and 5ghz. I realy do not think I need more bandwidth for my IoT gear. I need a standard for the end devices and a home controller aka things that should be designed to last for decades vs thing that should be regularly updated. The only real good thing I see from this is your average consumer gateway will have a radio that connects to our IoT devices and the encryption is stronger than what we have seen so far.
You do realize that SPI master is very easy to implement, after all you never have to react to a clock. Take a quick look for people trying to bit bang a SPI slave under linux not so much success. Yes their are bitbanged drivers find one that has to follow a clock and do that for a non trivial protocol at an appreciable speed. Now sow me something that does this in userspace. The marginal cost to do it "right" for a hobby project is trivial, hell the ESP8266s are cheaper than you can add a network connection to a $5 rpi. You're assuming they are going to write kernel code, compile it for a rpi etc etc etc thats a lot more involved that your typical maker with a rpi is capable of. A more reasonable case for a rpi is userspace code python or whatever.
Since you seem to like links here goes https://pypi.python.org/pypi/R... yup they say flat out entirely unsuitable for anything thats timing critical, use an arduino.
Sure you can use just about anything to do gpio work that does not make it optimal. So an rpi is not realy a reasonable replacement for an arduino, in fact the work together rather well.
There have been attempts. Simple robotic controls etc are not that hard, the rpi breaks down when trying to do things that need tight and continuous timing. It's pretty easy to use a dedicated micro for anything that timing sensitive and connect it up to a rpi for higher level logic.
Things like the ESP8266 with a much higher clock rate realy fill that in between niche. Wifi and IP stack and enough ram and excess CPU to make them useful while still being dirt cheap at $5 for a complete breadboard friendly design but without OS overhead.
And you have never heard of interrupt latency, You're not going to bit by bit decode anything of any significant speed on any multitasking OS. Interrupts are great but PC devices all have some sort of buffer. 80's parallel port uses a latch / ack setup, I'm old enough to remember 8250 UARTS and not being able to get past 9600 baud reliably. Try turning off interrupt coalescing on a 10gb nic, receiving min sized packets at line rate and watch any OS cry. To my knoledge linux does not bit bang any common device for any significant amount of time. There were some interesting used for LPT ports in the 90's they were neither realy high speed or very reliable.
Nope the PI is a much higher level board running a multitasking operating system. You're not going to bit bang any but the most simple and slow interface reliably on that. Sure if your making LED blinky lights it's fine. Decode or send some proprietary RF coms not so much. Pretty much it's unsuitable for anything but realy basic relay type work.
Mind you the useful uno clones are about $5 as well. ESP8266 also about $5 and the new ones are breadboard friendly as well thats a huge upgrade in CPU umph.
Your average consumer grade nat router that supports ipv6 has a default stateful firewall blocking unwanted inbound connections. Really no different than ipv4 with nat.
Show me a router that defaults to NAT for IPv4 and does not default to allowing nothing inbound IPv6. Now is it commonly used?
I've yet to see any, it's not realy any harder to run the state machine for NAT than IPv4 or IPv6 connected (ok some more bits). Ipv6 has some required to work bits but thats pretty tame as far as security.
Now I've seen some badly made ipv6 stacks as to ddos/port scanning but thats on network gear that frankly had ipv6 as a checkbox not a feature (Ya know those IPv6 in software L3 switches).
It's CT we are loosing our professionals due to our high costs of living etc. As a business owner in state it's getting harder and harder to get qualified people. Sure plenty of people with years in big corp and a 20 year old skillset. Our mass transit is basically New Haven to NYC. Right now I have a lot of remote workers because they can buy a house for a less than a couples yearly income in TN or similar. Most of my 30-50 somethings are here because they can not easily or with our major ramifications move, divorced families with child custody etc.
Mind you I happen to like CT but I live on the rural edge of suburbia and send my kid to private school.
You're trying to count SS as part of the budget. It should be separate (needs a constitutional firewall to be effective also useful for other specific purpose taxes), We still have not payed anything but the SS payroll tax and interest on securites. To add insult to injury they then try to claim that paying back the special non marketable treasury securities is funding SS, no it's paying back a loan + below market interest.
Not sure about the early 70's but in the mid 90's when I no longer had a need for clearance I no longer had it and had to sign a bunch of paperwork to that effect.
You do not understand how classified etc works. It's not about the markings it's about the content. If you can legitimately mark it as classified later it always was classified and she was instructed how to understand this. The corner case is something that seems entirely unrelated to anything and then turns out to be part of a state secret, as in you need other knowledge to know that this is classified. All the markings do it make it entirely unambiguous.
It realy does not matter if they were or were not classified, 2009 Federal Records Act requires all emails that are part of official business be preserved by the federal government. The Classified not classified bit is political spin to keep the discussion on that not the much broader law she violated.
Things like this do not affect the corp version at all. It's specific to people using MS not corp AD servers. We have had key escrow as an optional part of AD for a long time at least in relation to drive/file encryption.
It's called Impeding Traffic it applies to all roadways around here most states have one. You have to show you were using reasonable caution. A bush next to the road is not enough reason. Ever drive in NYC highways? Pedestrians on the other side of a jersey barrier feet away from traffic on the far side of a commercial truck.
Great for you that you never hit a mammal, friend had a buck jump from an embankment down 10 feet onto the roof of his truck while doing the posted 65 ish. You avoid that how? By your rules he should have been driving slower or did he need a flagman walking on the embankment just in case? These things are tradeoffs not absolutes.
I would not place my life in the hands of an AV in any but the most controlled circumstances.
An AV should do the right thing and break (while watching the car behind wont rear end you). An AV needs to treat it's occupants as the most important it's the only safe assumption.
A kid hurdles a guardrail through a bush, you do not have time to react nor is that a reasonable assumption of something that will happen. You want everybody to have racing level driving skills with them turned on all the time (which to get pretty much requires driving on the thin line between fast and crash) and to drive with the assumption that deaf dumb blind child is standing just past your field of view. Hate to break it to you but you're often legally required to achieve a minimum speed unless you have good reason. The odd chance that something might run out is not reasonable. So I'll repeat in many places you're required by law to not obstruct the flow of traffic. Your opinions on safe driving do not match up with the law or how it's enforced. It's true their are no unavoidable accidents, if you do not drive you can not have an automobile accident. But we balance the chance of accident with efficiency to do otherwise is an excessive waste of everybody's time.
As I said not enough time to signal etc think 20 feet at 50mph . Kids jump guardrails all the time. At 20f at 50mph normal human reaction (forget processing time) you have already hit them before you realize they are there. Jersey barriers do very well being run into from the side, you do not want to hit wire rails with a modern car it starts looking like a cheese wire, your fairly standard galvanized metal ones have a lot of give but I still dont want to hit one head on again would rather scrape the side than try and play drift king. In any event I'm not legally or morally obligated to put me and mine at risk for somebody working on a darwin award. While I was childless/without any dependents sure I would take some risks to avoid tboning an idiot in a minivan not their kids fault their parent is an idiot after all, now I'll pick mine over somebody that did something stupid every time (getting in front of a car as such to require them to evade you is by nature stupid and illegal).
At the end of the day you can not legally drive and be assured to be able to stop/avoid something that jumps out in front of you from concealment all the time. We have minimum speed and keeping up with traffic laws for a reason as cars going far slower than the accepted norm are more dangerous than something jumping out from concealment. We have to account for reasonable hazards and balance that vs time elsewise were all driving at 10mph just in case or do you want to go back to enforcing flagmen walking in front of cars (still on the books in some towns around here)? Good civic planing can do wonders at keeping cars separate from bikes and pedestrians for all but the last portion of a journey, but thats not useful for established area's that are a mismash.
USB-C is the best current option as in 3.1's power delivery 2.0. Mind you it needs a data condom to be safe since you have digital interface to negotiate power delivery. In any event anything required by law should not require any licensing etc.
You entirely missed guard rails on each side (no breakdowns/shoulder) and no distance to react (kid comes through bushes) for my rather contrived scenario. Thus no room to put her sideways and avoid putting the front/back end into the truck. It realy does not matter as even with your 3rd option your still looking at a head on with a truck that's your fault, putting her in the ditch thats your fault or hitting the kid thats not your fault. I'm quite familiar with "advanced" driving raced quarter mile and rally in my youth. The average driver does not have the skills or the thinking to put her sideways nor do we require them to have these skills and will probably punished them for doing so (suddenly that wrongful death suit for you loosing control and running over their kid vs hitting a kid who ran out from bushes), your average SUV/Minivan will end up rolling over possibly over the kid. If were talking about general safety putting on brakes that didn't suck coupled with antilock systems that also didn't suck and requiring tires that dont suck (read low rolling resistance), mind you all three add weight/complexity/reduce fuel efficiency. In the real world I've found a sports car as a daily driver advantages are getting out the soccer moms way and breaking faster than 99% of whats oth their. I'll take that slow speed rear end collision that is by law around here always their fault and get compensated for my time damages and loss of resale value.
In any event the automated car should do the safest thing for the occupants with the information it has. For that scenario it's break as hard as possible and hit the kid while saving the video etc so you win the wrongful death suit as the kid won a darwin award. Something more advanced might risk rubbing on those guardrails but these systems tend to be very conservative by design.
IoT can be very useful but it needs standards. My house knows what temperature it is inside the fridge freezer and chest freezer out in the garage, this is useful to me, both in the hey my son forgot to properly close the chest freezer or the odd mechanical/electrical failure. It knows if people are home and when people are going to be getting home. It knows when were going on a weekend trip. This can save me money by kicking back heating/cooling hot water (yea I know instant hot water is the rage but the 15 a month to get NG destroys any savings) even hot tub and pool temps. All in all it's a lot of easy and cheap to get information that's useful. None of it needs to leave my house. All of it needs to be behind a smart controller that works with everything. That controller acts as an application specific firewall to the cloud(s) or as the complete controller.
The IoT model that's a cheap wifi sensor backed to the cloud is broken, you have IP devices that are going into things with 20+ year life expectancies. You have long term devices that are powered by fly by night, hope they are around in 3 years forget 30. My house is 61 years old, can you imagine some of these company's phone the cloud in wall dimmers still working then? Can you imagine your average homeowner trying to replace a house full of in wall dimmers and outlets that no longer work?
Who said selectable? In any event it's safe to assume the fully automated car is obeying all related traffic laws etc. Obeying all the laws does not mean it will never be in a situation where it has to choose. Easy example is 50mph speed limit rural roads guard rails on each side, kid pops out through a hedge and runs into road after a ball or whatever, you have an oncoming truck doing 50 do you hit the kid or do a head on into the truck you have no time to effectively break or any forewarning of the event. It's perfectly reasonable to hit the kid in some cases you will even be sited for hitting the truck.
What you want is automated taxies that's fine sell it as a service. If you own it you're entitled to modify it. We can not nor should we restrict travel it's a basic right so should be access to any shared property like roads. Restricting people because something might happen is immoral the whole evil of thought crimes. If somebody mods their vehicle and that's the primary reason it injures another sure thats civil and possibly criminal. But to say you do not have freedom of movement unless your using state sanction software for safety reasons is just far far to easy to be abused.

Are you filtering for things like ESC j n that is an epson reverse linefeed. It realy was not that hard to get a general purpose line printer to spit back up and overprint with random strings.
I use wired zones for my perimeter, I have some wireless motion but thats more belt and suspenders for the security side and drives the HA system.
This is all about getting something dirt cheap to install and maintain to meet the requirements for the homeowners policy discount.
