How about starting with the fact the HMG is spying on your behaviour 24/7/365 and will retain that information indefinitely because they can.
Don't type anything that's going over the internet that you wouldn't mind at least a dozen complete strangers reading, again not because you're important or famous, but because there's nothing stopping them if they decide to do so.
That should be a good starting point.
Sorry but that's the bottom line.
Your widget (LoRA Low power Radio Association?) runs in sunlight and does an orderly power down when illumination levels fall down.
Batteries are a real weakness for this stuff, like wireless alarm nodes that have to keep sending out "I'm allright messages" that burn through batteries.
And this company should have most peoples red lining.
So basically they can do it if you have a whole server farm at your disposal and are ready to wear a helmet that's heavier than the clunker F35 pilots are expected to wear.
Sounds like they are going to need a shedload of either GPU porting or crafting their own custom ASICs to get the design down that far.and/or slashing the resolution and frame rate of course.
In the UK at least one village basically set up its own ISP to get an FO cable in for broadband.
It's not a council thing, it's a residents thing. Basically a private company.
Now I'm not really sure if locals in a town in the US could not set up something similar.
And as a local small business would they be eligible for a council grant to encourage small businesses to set up in their town?
Tough to do. Needs good people working together and determination but otherwise you pay the big telco prices for your access.
That makes absolutely no sense.
The only way they can make this work depends on what the current SOP for fueling satellites is. Most of them will be with the toxic NTO//UDMH combo, the others with Xenon for an ion thruster..it the tanks are loaded with self sealing 2 part connectors on the skin of the satellite then it can move into position and dock with the bird. But otherwise this is something that's got to designed in from the start, so you need to get someone to do this.
Running out of station keeping propellant is the cause of comm sats ending life so it's potentially got a lot of market.
Definitely worth a shot.
Want to bet that was the first time it was found?
I doubt it.
Yes libraries allow you to leverage previous developers work and (depending on how good the fit) give massive gains in productivity.
But designing a good library (sensible named functions. one name doing one job so you can decide what to string together) is damm tricky. OTOH writing crypto is damm tricky too.
The trouble of course is that the ways that work (detailed software structure planning, code walkthroughs, scanning code for further examples of the same code failing) are time consuming and expensive. PHB's would rather "invest" the money in more new shiny features. Bugs? Who cares as long it's keeping place with competitor X.
But I don't know enough about US business to say what that is.*
*Although I'm betting it'll be another bailout for the Detroit car makers. Ironic as in Europe Ford's rep for car reliability has been rising. Not bad cars as long as they aren't actually designed for the US market, or possibly designed by USians.
Welllllll.
The oil industry has spent a shedload of cash over the years collecting seismic data (roughly 13bits resolution for the IT angle) and every so often a new version of the visualization software comes out with some new algorithms to squeeze just that little extra smidgen of resolution out of the tapes.
For real S&G one day very narrow fingers of the oil bearing strata under the rest of the Middle East are found projecting under Israel, who sets up drilling rigs and then applies to join OPEC
With, as they say, "Hilarious consequences."
Great story.
Not true.
In fact each of the engines had 13 "computers" or controllers to do the analysis, covering inlets, outlets, after burners etc.
This is the 60's. "Computer" does not have to be digital. AFAIK most of them were analogue. Operational amplifiers and sets of resistors.
But calibrating them....
However you're right the design pushed the SOA a long way. Duncan Sandys had done a first class job of kneecapping the UK military aircraft industry in 1957 so they had limited experience of >M1 flight. It was said at the time Concorde was as challenging to Britain and France as Apollo was to the US, but in reality it was more like the Shuttle.
BTW the French wanted it to be even smaller and shorter range. It took IIRC 2 re-designs before the French grudgingly accepted it had to be at least 100 passengers. Ideally it should have been able to fly from Frankfurt, the other big European transport hub for the US (and that would have given the Schipol as well).
Something I found out only recently, so did Concorde.
Apparently the air frame grew so much in flight their was a pronounced gap between the back wall of the Flight Engineer's console and the rear cockpit bulkhead which you could put your fingers into.
Closed up by the time it came to a halt.
Not really.
Concorde's mfg were well aware they were the only civil aircraft with reheat and had they got to a 17th Concorde one of the upgrades was deleting it, due to design improvements they'd identified from flight data.
People also forget Concorde did not fly in 'burner above about M1.2, IE it was just used to punch through the sound barrier. It was "super cruise" before most people ever used the term..
That said I thought they also scrapped the original "laughing gas and tire rubber" hybrid engine due to excess vibrations.
That seemed a key part of the design so replacing it was not going to be trivial.
BTW 15Km lets you put a much bigger nozzle on a rocket engine without fear of flow separation, which can put a few handy secs on the Isp (somewhere between 5 and 20 roughly).
Let's hope the now return to a more steady pace and get to paying passenger time.
Surprising they let it go.
But kind of glad they are out on their own again.
From what' I've seen it's not the capacity of a cloud that's the problem. It's the bandwidth in the pipes, and the bandwidth the cloud supplier will charge you for that makes it tough.
Let's see what happens.
Due to the strict reliability requirement (1 failure in 1 billion hrs of operation, although I'd guess the landing portion of a flight takes no more than about 10 mins) no actual processor in site. Not even sure if it was all analouge.
Of course that was before WAIS and differential GPS put accuracy in the cm range.
And yet despite the catalogue of fu**ups to study people keep managing to do it.
Or as the introduction to Peopleware put it
"Somewhere today someone is writing a Purchase Ledger system from scratch, and failing."
Of course 35 years later that statement cannot possibly still be true, can it?
Can it?
