I just read battery draining..

I'm not sure if it's the interviewee or the interviewer, but Solar systems move around.
We have loads of evidence for this in our own solar system, just because a planet is currently in a close orbit around a star doesn't necessarily mean it formed there.
The same person with 20,000 different job titles?
There seems to me to be two possible avenues:
Both with Time delayed operation
1. Slow switching transistors (phase change), but with retained state, so you could set a switch state, but only action it when needed, this I think is where the potential power savings are intended to come from in the circuit.
2. Potential Analogue computer routes.
The main issue will always be the mechanical thermal gradients in the circuit, I doubt you'd be overclocking this to 7Ghz (not that it would stop someone from trying).
But for applications where speed is less of an issue and integrity is high there could be products.

Given its a 2-3yr round trip with current tech, probably with a lot of work in between, I doubt it would be classed as a holiday.
Nuke it from orbit, only way to be sure!
Whether it's testing or just development, all the behaviour of the system will be defined by requirements.
If these requirements are incomplete or inadequate, you can test till the cows come home, but it won't find any bugs.
The issue with Level 4/5 autonomy is the basic functionality is fairly simple, but the number of edge and corner cases out in the real world is huge!!! Millions upon Millions, only so many can be catered for and so there will be gaps in your requirements and testing will not cover these scenarios.
The use of Neural Networks is an attempt to cover for the unexpected, but these systems will have limitations and we won't know what they are until we use them.
The Earth could have chemically formed it's own water + plus water trapped in rocks already here.
I can't see the 2 stage approach working, there isn't a need to reach orbital velocity (the reason for multiple stages), but the first stage may achieve enough velocity and altitude for a sub-orbital trajectory on it's own.
Raptor wouldn't work for the F9, the tanks are sized for the Fuel/Oxidiser ratio. Methane needs a lot more fuel (unchilled & unpressurised volume) for the equivalent energy.
Basically they would have to redesign the whole rocket, at which point build something bigger.
Sad as I must say this, on certain points Bob is correct, as much as he is annoying:
1. Size, for some reason they are obsessed with building bigger and bigger reactors. These designs run on Magnetism, anyone heard of the inverse square law.
2. Neutron/Gamma generation - this, I think, is the power generation lobby, all they know is steam generation for large scale systems.
There are other options for fusion other than D+T, such as Aneutronic reactions (He3, being one form), these typically produce ions from the reaction, which depending on the reactor type can be used to generate electricity directly from the reaction.
Many years ago I saw a weird conspiracy theory stating that the Tokamak was invented (in Soviet Russia) to bankrupt the West, as much as I hate to think that there is any truth in what a lot of these nut jobs are coming up with, in this case, there is a possibility.
The real issue with JET and ITER is what it is doing to Fusion research funding, they have been pouring billions in over the last few decades and while I definitely believe the research performed at JET has been very useful, ITER is a white elephant government funding vacuum.
Taking away funding from other concepts, the phrase "Don't put all your eggs in one basket!" comes to mind.
Britain being the only nation to develop the capability to launch a satellite, and then give it up.
Technically they gave up before they gained the capability, but they launched the thing anyway.

"Now, if people would only *Read* the "Terms and Conditions". I'd guess less than 1% of users read any, let alone all, of any T&C."
Unfortunately you need a law degree and many years experience of contract law to understand these things, such is how they are written.
Someone also worked out that if we actually read all the T&Cs forced upon us over a lifetime it would take ~10 years to read all of them.

So we can safely assume that you've never made software for mass-produced small objects with price and/or safety constraints?

You haven't because no one knows and you won't because it will be politically unpalatable.
Of the following:
"The path to Success is always beset with failure!"
Ah but there are a lot fewer drones, maybe they are lonely.
"Somali pirates could've made a nice live target, but I believe their numbers have diminished significantly in recent times."
Nah they just scare easily, but they'll be back and in greater numbers!
Yes, "you no longer own your data, we own your data and any attempt to use said data will result in severe penalties!"
How would they know they are pollutants, unless they had been monitoring over centuries?
Accessing the information from the card requires physical access and is payment limited as has been stated, a net connected smart phone can be breached from the other side of the world, potentially unbeknown to the user.
The Window Of Opportunity for the attack is much wider which increases the risk massively.
And what do they do in the event of a power failure?
That's because the jobs to your car usually take 10-15mins, they're charging you £100+/hr to clean your car.
"I have come to believe that there are a number of bad actors teaching people to code who feel that including basic security is to be avoided under all circumstances."
That is more to do with laziness and publishers, said tutor has been procrastinating over their book for the last X years and doesn't want to have to complicate matters needing to re-write it to cover security basics, plus the course material is easier to teach, so from their perspective win-win.
90-95% of the code is probably stolen from some online site.
They don't really know how it works and probably would just shrug shoulders if you asked them to secure it, added with "bosses" who would probably instruct you to avoid doing work they didn't feel was necessary.
North and South are still technically at war.

"Exactly like the Fiat original, in fact.
But probably much, much less liable to fall apart due to rust at the first touch of rain.."
The Lada's are made from thicker steel.
Live streamed HD video from the Lunar surface I think they mean. Annoying as it is.
Micro < Discrete generally other than for really, really simple stuff and then only in massive volumes.
Fundamentally more components = more cost, it's not the individual parts, it's the PCB and assembly.
Which requires more R&D because it's more complex, plus there is a high probably of production issues due to that complexity.
Also as the bulk of the behaviour of the system is SW, if there is a problem you can replace it with a simple firmware upgrade. A design issue in your analogue circuit generally results in replacing/repairing the whole circuit.
Actually, with sufficient development it's a bloody clever idea, at low speed impacts you want a relatively soft deformation structure, but with high speed impacts you want a deformation structure that is much more rigid (to absorb the energy).
The problem is making it act reliably and consistently. Especially in the high speed impact scenario, I.e. You don't want your tech becoming the weak link in the chain compromising the safety capabilities of the vehicle.
Same with training material, when required to use the dreaded presentation application (shall not be named).
Try and drop in some humour at least every 3-4 slides, especially if you're training engineers, it attempts to stem the DBPP.
Plus while snoring interrupting something complex that needs to be explained can be hilarious, starting all over again with complex material is not so controlled humour benefits all.
"Why does a fridge need a microprocessor?"
Cost, it's usually cheaper to put a micro + code, than design/test an analogue circuit.
With the Micro usually working out cheaper component wise.
Plus they can potentially add features with a firmware update.
So it could also be wrong, but it's not looking good, we'll have to wait for JWST to come online for a better chance.
Of reasons, when given the choice, not to live in rented accommodation.
It's Saturn V and 140,000kg.
Someone's stopped taking their meds again by the sound of it.
"If this chip were part of a diagnostic tool (OBD, etc.), we'd want to use Rx to read the car's bus, but keep Tx limited to diagnostic-required messages (such as requests for special data from onboard devices). It would be up to the diagnostic tool to keep the data sandboxed and not broadcast elsewhere."
You can put a CAN gateway between the Diagnostic port and the main vehicle bus, but many don't due to cost.
@JamesPond, Yes and No, being on the other side and actually having implemented the diagnostics on said components that you talk to, the level of security is only appropriate to the task, e.g. reprogramming, but many of the features that a malicious actor would be interested in are not always protected or at least sufficiently protected.
Much of the server based security setups are just more obscurity, the algorithms used are generally still primitive and easily cracked.
The databus itself is not encrypted or authenticated (currently), therefore the biggest weakness is either Spoofing or Denial Of Service.
With many modern vehicles having level 2+ autonomy this becomes even more of a risk as many of these features operate over the CAN bus.
The industry is changing and some of the next generation vehicles will have improvements, but there is still a long way to go.
The reaction Tri-Alpha and some other groups (Focus Fusion etc) are aiming for an Aneutronic design, these use pBoron-Hydrogen for the reaction rather than D-T.
The advantage of this is there are no neutrons released from the reaction and minimal neutrons released from subsequent interactions.
The advantage is the reaction produces helium ions, depending on the reactor type these can be focussed.
Therefore you can generate electricity directly from the reaction and the electricity generating equipment effectively becomes solid state.
The problem with this design is it requires much higher temperatures and pressures to 'ignite' the reaction.
It's also based on a big assumption, a very arrogant one at that, that true AI will be designed.
