I suspect that you would have used Windows devices.
Mix, the tills were windoz the back end paired store servers were AIX boxes with mirrored databases. Cloud is still a risk if you can't access the cloud, little things like a backhoe cutting the fibre cable.
In a few years the "industry-standard software applications" and user management will all be in the cloud allowing us to use any operating system/desktop as long as it has a supported browser.
Yep, no cloud access from one of several faults means a nice single point of failure. In my long life I've seen this happen too many times. A major retail store that I was involved in actually got to the stage that each till (PC with scanner and draw attached) could standalone. Backed up by the whole shop being able to standalone.
If they're going to pull water from the (relatively) dry atmosphere rather than take what little groundwater there is there to support the locals, won't that affect how much water ends up in the ground for those locals?
The problem is that it is a desert, there is no ground water! The locals rely on bore water which is high in mineral content and comes from rain that fell years ago and in a different place.
The BIG issue with that is you would need to change ALL the calls in the legacy code and then carry out a extremely comprehensive test.
This of course will take a lot of time and money. In a commercial world who will be paying for that! Better to just keep the old code in place doing its job and only, only replace / rewrite when you have to.
Refactoring old code to remove all the dangerous calls to things like memset, memcpy, memcmp, strcpy, strcmp etc will normally end up in a complete rewrite as the old legacy code will have had the boot prints of multiple developers over the years it has been in production. Some of those developers have been good and others well...
Some of the stuff I've worked on has been over 30 years old and has been so bodged and patched that most of the job is just trying to work out what the code does. In some cases there have been bits of code that have been logically commented out because they provided a function that is no longer needed.
This problem is not specific to any language one of the worst legacy systems I was involved with was written in COBOL.
One rule I found useful is "If it is not broken don't fix it!"
"A programming language designer should be responsible for the mistakes made by programmers using the language."
Seriously! Humans have an amazing ability for stupidity. To paraphrase Einstien "the universe is finite, human stupidity is infinite"
The phrases I love hearing are:
"Well it appeared to be a good idea at the time"
"Whoa did not see that coming"
"No one would ever do that/ be that stupid"
"This is only a quick and dirty fix it doesn't need to go into production..."
One of the major reasons is legacy code. I was involved in the maintenance of a very large retail system that had its roots in MS-DOS.
There were still large parts that used strcpy strcmp etc. No one wanted to refactor those as they worked. However we did have warnings maxed with warnings as errors and just added a define around each call to hide that specific warning.
The other rule was if you had to make any changes in that area which meant it would be tested you were to change the strcpy/strcmp etc. The preferred fix was to replace the char * with a std::string or CString.
You will require considerably less concrete for a window farm and there is no waste to entomb and hide away somewhere safe for 10,000 years.
The issue is you can't recycle a nuclear reactor as the material is contaminated and must be entombed. At least with a window farm it can all be recycled.
Not sure where you get your costings from. But here in australia most installations ate about 6-10kw at about $6k so 30kw of cells would be about $30k and batteries are a similar cost per kw. so for a 30kw system (which BTW is extremely massive) would cost about $60k AUD about £35k.
Also not sure why you would need 30kw as here in aus most installation are around 6kw
killing a pregnant woman earns you TWO murder charges in any state.
This 'law' just exposes the pure hypocrisy in states like Texas where a pregnant woman gets done for driving an express car lane where you must have two or more people in your car.
So a foetus is a person for murder but not for car pooling but if you kill that pregnant woman in a car accident the foetus is counted against you in vehicular homicide.
Beam me up Scotty...
Just once I would actually like to see the bloody BA's specify actual NFR's (non functional requirements) that would allow the dev's to design and develop against.
I would also like the bloody project managers and the rest of the pointy haired ones provide the infrastructure that would meet the NFR's.
I remember one project where they would not provide a UPS to develop and test with so that when it went into production it was on a wing and a prayer and first power fail it didn't detect that it was running on battery and crashed damaging the database. Doh!
Assembler. And before that, nightmare territory of having to program directly at the per-bit level, by "literally" throwing the switches.
I loved those switches. Hand translating your code, loading it into the console via the switches and run.
Later once you had a tape you would manually enter the boot loader and run. Happy, Happy Joy, Joy. Real hacking.
Also the problem may be environmental. A nice piece of rust where two parts of the antenna mast are joined can act as a diode and mix several different xmitter signals together and radiate spurious signals across a wide frequency range.
Depending on the physical distance it could even be a bit of rusty fence!
I haven't looked at the allowable 5G C band emissions or the input specs of radar altimiters, so I can't say if the concerns are valid or not.
One issue that hasn't been brought up is where the 5G service has a xmitter or antenna fault and is splatting spurious emissions that may appear in the radar altimeter receiver passband.
Something like a dry joint or corrosion in a connector can make a nice little diode mixer.
Totally agree, I don't trust him or his government.
Here in australia the politicians can troll as much as they want they are covered under what they call "Parliamentary privilege".
This ability "to unmask anonymous online trolls" means they can go after the whistle blowers etc that show just how corrupt and incompetent the government is.
Scotty from marketing is trying to use this so he can ignore his promise to create an integrity commission as the last thing he wants is anyone looking too closely at many of things that he and his government have done.
These are the australian brush tail possum and may be small and cute in austalia but in NZ particularly in the south island and around Dunedin they have grown big. In aus they are 2-5kg but in the south island they can be up to 14kg with extremely nasty sharp teeth and sharp claws that carry some very nasty bacteria.
One rule we used was if you are opening the shed or outside dunny and you hear something inside is get the hell out of the way as if it is an adult possum it is going to go through or over you to get to the outside. And it is highly likely you will come off badly!
Think about how many batteries that would take.
Bugger all, In Aus as a rough guide (as at January 2021) a 5kWh battery system fully installed would likely cost around $5000 – $9000, a 10kWh battery system could cost $7500 – $12,000 the 5kWh battery pack is about the size of a large suitcase and mounts on the outside wall.
Most roof top solar is between 3 and 6 kWh so matches the batteries nicely. I have a small inner city house UK terrace style and I can fit 3-6 kWh of solar panels no problem.
