No boot ROM means that a hardware device constructed from discrete logic and analog chips directly demodulates digital data from the radio, addresses the memory, and writes the data. Once this process is completed, it de-asserts the RESET line of the CPU and the CPU starts executing from an address in memory. Really no ROM!
Ok! (Very) remote pre-boot DMA, nice!
Thanks for the expdanded explanation,
The situation for AMSAT is still pretty bad, as far as I've heard. As a radio amateur group (and one that has launched quite a few satellites as space hitch-hikers) they can't afford the good stuff, but they get some donated by NASA and some of the commercial satellite companies. Only a few years ago they were still using the 1802 as their main vehicle controller, as that was their main choice in silicon-on-sapphire CPUs. They get some donations of space-qualified solar cells. They scrub their memory continuously, They use no boot ROMS. The program is loaded entirely by hardware, and then the CPU is started.
Bruce, what do you mean by "...no boot ROMS.... loaded entirely by hardware" ?
Is this the long sought after counter-example to Betteridge's Law where the response to a question mark is always "yes" ?

Awaiting your mea culpa.
The Brazillians just wanted to make sure that the American athletes felt right at home.
As I understand it, this is not the point of the chip and signature system. The point of the chip is to make it much much harder to clone the card. With the old non-chip system, all someone needs is your CC number. They can program that into the magnetic strip and start using it. Many places like fast food never even required signatures. Gas stations only required zip codes, and then only sometimes.
My biggest problem with chip and pin is that banks disclaim themselves of all liability for transactions that go through with a valid PIN, as they feel the chip is secure enough to prove that the card must have been real and if the pin was used, that's because you intended to do it. Nevermind that cards can still be cloned and pin numbers skimmed. This is also a problem if someone steels your card and knows your pin, you're on the hook for everything. Happened to a guy here in Canada when his ex girlfriend stole his card. Back when they were dating he shared his pin with her (big mistake... but what about marriages that end in divorce?).
I think that most people miss the point of this. I don't thnk the banks truly believe that chip and pin is more secure, what I think they do believe is that they can use it as an excuse to disclaim any and all liability. In other words it's all about making sure the account holder bears all the risk.
As to your second point (divorce); I've been married for 15 years and I have a joint account with my spouse but we do not know each other's PIN's. Never share your PIN with _anyone_.
When I read the headline I thought it said "Disaster-as-a-service".
Even though it's been 3 years since I worked for them I think the 13 years that I did spend there could be best summed up by that phrase.
still better than my hp-drive, running ms-car. it went into hybernation at a railway crossing the other day and then got stuck in an endless update loop. pushed it to a hp-garage, but they told me it was microsoft's fault. had it towed to a ms-garage where they told me hp was to blame - but they installed the free upgrade they had already secretly put in my trunk on my last visit. now it's not as fast as it used to be but on the other hand the steering wheel is now back on same place it used to be before the last update.
apple car looks nice, but i've heard it mysteriously shrinks over time.

I don't know about anyone else, but if I go to a real sit-down restaurant, I want an actual human server, not a robot or some other form of 'automation', and I sure as heck don't want a robot or some automation preparing my food, either. If that was my only other choice then I'd just as soon stay home and cook my own food.
Given the direction in which these "trade" deals are going I suspect it won't be too long before cooking at home becomes prohibitive.
Just imagine vastly expanded "Intellectual property" laws integrated with micropayments and the internet-of-things:
You'll have to pay royalties to everyone from Monsanto (base food stuffs), through Samsung (gotta pay each time you use the microwave) to whoever wrote the recipe (recipe's aren't currently copyrightable but lets wait and see).
Of course you could get some recipe advice via a cooking show that you watch on your IOT fridge.
You'll have to watch all the ads now of course as adblockers are a way of helping the terrorists.
Think I'm trolling? This scenario isn't a big stretch from where we're at now.
Wait staff works for tips, and I doubt a change in minimum wage will change this. If a restaurant turns $3K/night in income, an increase in back room labor costs from $60 to $170 shouldn't hit the cost of a $15 entree too hard, as you say: maybe $0.30.
However, in places that operate entirely on minimum wage workers, tripling the cost of labor is going to have a noticeable effect on the cost of served food - your $4 value meal might have to jump to $5.
Tips used to be a (literal) foreign concept here in Australia until very recently.
Why? Because wait staff were paid a reasonable wage and didn't need to rely on tips to get by.
Unfortunately it's changing due to the wholesale importing of all things American into our culture.
What I don't understand is it only with wait staff? Surely if it's such a great idea then everyone should be working for tips?
Many of us in the west will instinctively think of this as a developing world scenario but really how different is it to the way things are heading in the developed world?
If you didn't get in in the good old days of, hell, the 90s, buying is not really an option anymore. A house I was looking at sold for $360k. For a 450sq foot house. Just barely bigger than my apartment.
Rents and Housing are absolutely out of control all over LA, not just SFO. I have no idea how anyone affords it on anything less than tech wages unless they're shacking up with 3 people. What's the point of making good money if you're spending it all on rent?
Damn! $360K wouldn't buy you an outside toilet in Sydney.... I always thought that somewhere like San Francisco would be well into the millions... I know that the minimum wage is higher here but even by proportion property prices in California is insanely cheap by our standards.
