it would simply pick a random number at startup and encode that in the beam's modulation
And, depending on the entropy pool used, how do you stop two vehicles setting the same number? And, if it's encoded into the beam, how do you stop the bad guys capturing and replaying a static encoding?
Answer to both - you can't with any confidence.
Not so easy if it's on a multilane road and is now blind to traffic between itself and the side of the road.
Indeed. Which would mean that each vehicle now needs to be generating an "I'm here" signal which is used in concert with the lidar.
Except that that system will then add an extra exploitable sensor - the Bad GuysTM will just scatter emitters for that signal over the road and thoroughly confuse everything.
And tying all the vehicles together into a senser-net won't fix it either - it'll make it more difficult to spoof stuff but it still won't make it impossible - it'll just increase the number of cracked sensor controllers in the vehicle.
Imagine your poor grandmother sitting through hundreds of voicemails from scammers, hoping the next message is from one of her children or grandchildren just calling to say hi.
Most of the people involved no longer have grandmothers - they sold them to the mystery meat market long ago to gain a few extra dollars..
The electorate then chose to punish the Lib-Dems for not stopping ALL the Tories' policies - and thus gave the subsequent Tory government a free rein with a majority.
And thus ensured that minor parties will *never* now accept a coalition on the basis that the majority party always gets credit for the joint successes and the minority partner always gets the blame for the joint failures.
I believe the correct symbol for nautical miles, which I assume you intended, to be "NM", although wikipedia states "M, NM, or nmi" are valid; not however simply "nm".
*Nods approvingly
Just when you think the younger pedantards are slipping, along comes one to reconfirm ones' faith in the future of pendantry.
Learn to speak properly. Everyone knows it's "you're going daahrn you slaaaaaaag!"
I say! You must be from the wilder parts of London old chap! We don't have language like that round here[1] you know! One must have standards..
[1] NNW London. Where I was dragged up. With a Middlesex postcode..
Let's hope they devise a "used asteroid" disposal system by then
Well, the moon is pretty close by and pretty uninhabited..
Failing that, there's an unimportant building in Washington, USA that could do with some remodelling[1]..
[1] Again. Party like it's 1812, just with bigger booms..
I remember (many, many moons ago, when I worked at a certain cellular base-station manuacturer that used a stylised bat-wing for a logo) having an arguement with the technical architect about the use of non-Intel processors (AMD had just bought out the K6 and I was quite keen on them).
His answer was to specify that non-Intel processors should never be used "because you knew what you got with Intel and their processors were bug-free".
The next day Intel revealed the news about the FooF microcode bug.
Oh, how we laughed.
And how do the camera efficiently upload the images they've captured to the server without access to the internet?
Private APN (which is effectively a private circuit).
Now it could be argued that a private APN == some sort of internet but I wouldn't equate them - any more than a private PTP circuit that goes via a single carrier is 'internet'.
Surely the first thing you do with a car is get the ECU mapped with a grown up config?
Assuming that you don't care about manufacturers warranty[1], yes.
[1] And, under some[2] circumstances, invalidating your insurance. Or, if you tell your insurance, raising the rate from "extortionate" to "selling first, second and third born".

you can't change the lan-side IP address of that thing
Wow. Just, wow.
(In a previous orkplace, our internal LAN was using 192.168.1.0/24 [not my decision, was in place when I joined and would be a nightmare to change becuase of hardcoded paths in stuff like industrial control equipment]. Then the Sales Director demanded, not unreasonably, that all his staff needed to use VPN from home. Most of them were using BT Home, which defaulted to using (you've guessed it) 192.168.1.0/24 for the LAN. Much hilarity ensued until I managed to get people instructions on how to change their Home Hub to use a different range..)
digital media with resistor ladder DACs fashioned from graphite pencil lead, and we did fine
You had digital media? Luxury! We 'ad all us fingers chopped off t'feed t'whippet and had to knit us replacements using us teeth and whatever bits of broken glass we could pull out of t'bed..
Kids today eh?
solved with a glass or two of a single malt.
Fond as I am of the Holy Water of Life as made in [Scotland, Ireland, Wales, England[1], India[2], Japan], I'm rather more into red wine at the moment.
[1] Yes - we have a proper, licensed whisky distillery. The Chapter 14 release from The English Whisky Company[3] is a very, very fine thing.
[2] Strange as it might sound, I had a bottle of Indian Whisky recently and it was rather drinkable. Can't remember the name though.
[3] I have no affiliation with them. I wish I did cos then I might be able to get a discount..
.. Yeah. Like my GP switching over to electronic prescriptions, complete with assurances that, even though my data may be shared with pharmacies, I have control over whether the pharmacies shares it with external bodies.
Except for the fact that the pharmacy policy isn't opt-out[1] - they are going to share your data with "partners within the same group of companies" but were remarkably shy about who those partners were or what they would use the data for.
And remarkably shy as to whether their partner companies would also pass data on to their partner companies. Apparently, it's up to me to investigate each partner individually.
[1] Yes - you can "op-out". But that means you have to select another pharmacy to get your prescription at and all the other pharmacies are either from the same company or don't do electronic prescriptions (at least, not with my GP). So, legally an opt-out system, but not in any practical way. Unless I want to forego my diabetes and migraine medication..
The gang of regular cats spot the intruder and attack it en masse, thus intruder cat is not a problem for long.
Indeed. With current gang of cats, we've yet to have a strange[1] cat in the house[2].
and at least a couple of them are psycho ninja fighters
Yup. At least two of them. And they all seem to be female. Funny how that happens[3]..
[1] It's a running joke that to be a cat in our household you pretty much have to be strange..
[2] Apart from next door's young male cat. But he's good friends with $SENIOR_MALE_CAT [4] so he doesn't count. Especially as $SENIOR_MALE_CAT is quite happy to return the favour and sit in their dining room window with him. And, since $NEXT_DOOR_CAT is about 6 years younger, ours has taught him road caution, just like he did with our younger cats[5]
[3] Female cats fight *very* differently from males. With males there's a lot of posturing and shouting before any actual combat (and often there isn't any combat). Females have more of an attitude of "I can't be bothered with that, I'm programmed to defend kits. I'm going to try to kill you without warning, even if it means I get hurt". Which is why, generally, male cats don't like fighting female cats. They don't fight fair.
[4] See previous post about his preferences..
[5] Except the little airhead social butterly tabby and white. If she was a Pathfinder character, her primary stat would most definately be Charisma and her dump-stat would be Int.. Which is why she has her pelvis held together by titanium rods, only the stump of a tail and no head of femur on the rear-left.
Works until the ginger f*** from two doors down hacks it and puts his own RFID identifier in the DB....
We haz RFID too. But mostly so the vet can identify the cat scraped up off the tarmac. And in our household, it wouldn't be the ginger hacking the cat door (except in the traditional sense of 'using a blunt object (his head) to break down obstacles").
No, it would be the half-Siamese ginger and white, assisted by his lovestruck assistant (sister of previous said ginger and the one who inherited the brains in that family) who has long adored said ginger-and-white despite the fact that he seems only interested in boys[1].
He is on the right-hand side of the intelligence bell-curve and she's part-ninja. Complete with patterned camoflage.
[1] And our senior female. But that just protective behaviour so that she doesn't rip his face off and use it to wipe her butt.
What if a rogue cat enters the house?
That could never happen, no sir. And any reports from my neighbours about two male cats bearing a striking resemblance to mine are pure fiction and probably made up by the dog[1].
[1] A Great Dane (allegedly m'lud). Who, quite sensibly, kept herself out of the affairs of her betters[2].
[2] Allegedly. Did I say allegedly?
They've only just started getting excited at all the things that could go wrong, and the possible consequences.
"Ah. I love the smell of a lawsuit in the morning[1]! Reminds me of London in 1966[2].."
[1] If high-priced lawyers work mornings. More likely, they have lowly-paid minions for that. After all, the coffee isn't goning to make itself!
[2] Date purely indicative and bears no relation to any real date, either actual or imagined. So there.
Morbidly I am now wondering how many more levels of hell this project can deliver
Think of a number. Multiply by the number of external "consultantants". Then multiply by their daily rate.
Add (number of project managers X number of senior managers involved).
Divide by (number of bottles of whisky you are allowed to drink daily at work+1)
