I’m not sure that’s always the case.
From a hardware point of view the shock to a system is at power up.
And even software For example I ran about ten windows 7 “machines” on vSphere on the “one task per machine” requirement. And unless a critical update forced a restart, some of those machines were never rebooted. In an 18 year period some of those machine never fell over. Probably the “one task per machine” is the clue.
As an old man of computing, first program 1969, and thought networks were pointless, my comments are probably not worth much but here goes anyway.
If you Data is not on media you own, it’s not your data anymore. If you keep your backups online (powered up and attached to the machine) they are not backups. Every few years as the price point comes down buy larger disks, copy your data, and put the old disk in the equivalent of your socks draw.
You will loose data , just not all of it.
I agree you can write code that apparently does not use a library buts it’s challenging.
I wrote my own PLAN compiler back in the day and even then some instructions were “ interpreted” by the exec.
Also there is an interesting article ( the reference escapes me at the moment) that showed how to permanently and undetectably hack a ‘c’ compiler.
To see what code you actually have, one needs to decompile the exec to its machine code. Well good luck with that on any large project.
The “trouble” comes in several forms.
From the built in obsolescence of my phone where apps I’m using cease to work, to no further security patches for my os (Windows 7 I’m looking at you) to no patches for the compiler and it’s library.
Even writing code in “lowest level” C there is some dependence on Libraries and don’t even start me on Java.
And our young aspirational coders need these “cloud” credentials on their CVs to even get an interview.
I believe Aurther C Clark said that when we no longer know how something works we will start believing it’s magic. Sigh!
If the Falcon has a large Brillo pad in each claw , it could tangle two rotors. Taking out two rotors on the same side should be enough ( so it cannot fly on chinook style) but “controlling”where it come so down still a problem.
Another thought - the magnets inside a disk drive are very powerful (disassemble one and “Ouch!”) would that be enough to disrupt the flight control electronics?
As a thought experiment that sounds interesting
As a real experiment which AI engine would you use.
Also I’m thinking any AI that correlates data one way between two devices, should also be trained to correlate data the other way - so in theory your infrared thermometer will (via the AI) produce the images your Gen1 NoIR cam would have taken.
I do not understand why just because an AI used historic data to work out a correlation it’s being called “fake”data.
Much more interesting to me is did they / will they create the inverse AI using the data from the MEGS-A before it went down to predict what the other instruments readings would be.
If so we could have software redundancy when we cannot afford to have hardware redundancy.
It seems elemental that any organisation would have at least one outer DMZ where all ports are closed by default (block all) and specific rules to open required ports.
If the organisation takes credit card payments in the UK, it’s a PCI requirement and no QSA should sign off a site without checking the actual firewall config not just the policy document.
Many years ago I was a software programmer and the ICL 1904 I was using at a client site stopped working. We were much closer to the hardware in those days.
The engineers ran a test and I poked my nose in asking about the results. I deduced addition was faulty, and persuaded them to do an addition (on the switches !! ) they did and told me I was wrong.
8 hours later they replaced the addition unit and all worked. when I asked what they had added it was 1 & 1 Had I specified FFFF and 1 it would have shown the problem - carry in bit 8 was faulty!
Still reminds me to specify exactly what I want when testing.
