Disgusting, those unelected eurocrats doing things to help me!

Because the camera's software is Windows-only.
We had some Vivotek cameras and the software recorder/manager supplied by them was surprising not crap, but it was over 5 years after UAC was enforced by MS that they fixed their software to not require the poor minimum-wage sod checking stuff to be administrator.
I am sure there are better options, but when faced with stuff that "works" mostly and spending weeks trying to find a better alternative you just put it on a Win7 VM for no updates and firewall the hell out of it.
More it applies to "service stations". Typically a motorway stop will have something like 6-8 pumps, so we are looking at something like 20MW available to provide 10 min charges for long-range support to commercial drivers, holidaymakers, etc. While folk would love to see 800 mile charge ranges I strongly suspect that we won't see that ever, but rather improved battery power density will be used to have a lighter and safer battery pack so cars in crashes don't go all Ford Pinto on the occupants.
Are any existing service stations going to be able to afford it?
If not then we are looking to move society in to a position where car and van use is largely local with long distance by train and similar. Not necessarily a bad thing, but without many fast charge points we will struggle to deal with the large number of people relying on on-street parking that has no reserved areas and local authorities who lack the budgets to electrify them. Even assuming the local infrastructure has enough capacity.
They love selling electricity.
And they hate replacing infrastructure that costs serious money to do. If you want a new supply you will be charged something like £120/m for the cable route for a domestic 3-phase arrangement (max load around 70kW, assuming the local substation has spare capacity). If you wanted the 2+MW that the above commentards have discussed for a 10 min charge you would have your own substation and 11kV supply. Have you tried asking the price for that?
You still need to sync the atomic clocks together in the first place, and to keep them agreeing afterwards (depending on the level of time accuracy you need)!
For that you need something like GPS to do it, so really it comes down to how many will pay extra for an atomic clock reference oscillator in addition to the GPS receiver and outdoor antenna, etc. Many should do it, if they are running essential services, but usually the bean counters say no...
We used to have one of the
SunOracle storage servers with the dual heads configured as active/passive and linked via both a Ethernet cable and a pair of RS232 lines. That was, allegedly, so it could synchronise configuration via the Ethernet link and had the RS232 as a final check on connectivity to avoid the "split brain" problem of both attempting to become master at once.
It was an utterly useless system. In the 5+ years we had it as primary storage it failed over a dozen times for various reasons and only occasionally did the passive head take over. We complained and raised a bug report with Oracle and they just said it was "working as designed" because it was only to take over if there was a kernel panic on the active head. Failing to serve files, its sole purpose in life, due to partial borking was not considered a problem apparently.
The conclusion we had was paying for professional systems by big companies is a waste of time. Sure we had a soft, strong and absorbent maintenance SLA but we would have had less trouble with a singe-head home made FreeNAS server and a watchdog daemon running.
For classic NTP operation it is recommended that you have 4 or more time servers configured on each client so they can detect problems including a broken/false clock source. That could be costly in hardware, so you might have 1 or 2 local servers from GPS that offer precise time due to low symmetric LAN delays and back it up with ones across the internet at large that can catch one of the GPS going massively stupid but only offer accuracy, on their own, to several/tens of milliseconds.
People complain about UI changes and install legacy GUI's to keep the old feel.
No, they do it to avoid the loss in productivity that comes from fscking around with an interface that works perfectly well.
Take the Windows GUI as an example, and compare the layout of win95 with win10 - can you point to a single change that actually makes life easier?
Oddly with the limited number of IPv4 addresses we ended up with NAT as the default for home routers and most small businesses, that automatically made "default deny" the standard for incoming connections. Of course that only lasted until we has UPnP breaking it for any dodgy software running on the user's PC, or the design goal of IPv6 offering access by default for ever device in existence.
And this highlights one flaw in the idea of authentication access to the network, as soon as someone's PC (or other device) is compromised it gets their access credentials, and often that is done via pull-requests now (email or web site malware) and so it can do the same to everything they have access to. So while such network rules might help reduce a free-for-all in the LAN, it really is not dealing with your typical ransomware attack for small business or home users. For they they need a immutable copy of important files, and some means to wipe and re-install the machine(s) impacted by it. The cloud-based accounts on offer promise this, but at what cost in on-going expense and in privacy?
Does that not strike fear in to your heart? Surly the number of useful libraries must be a lot, lot, less! How many of them were written by someone not bothering to check if it is already standardised, and making new and exciting mistakes again and again?
GNUradio is not a good example as a project as the code base and build system seems to be made up as they go along by folks with little in common, and often will not build from source! WTF are they doing?
As soon as you see a project that has made its own build-tool instead of a common utility you can see there is crap coming...
The engineering cost is a key factor, but if your business has those folks for other reasons then getting them to spend a small amount of their time on the feeding and watering of your servers makes sense.
But as you say, for small non-tech businesses, or non-core stuff, it can be well worth the cost for a managed service (e.g. non-classified email, accounting package, etc).
I have been to India once and it is a nice place to visit.
But they have as obnoxious and self-opinionated politicians as they come and with a back story of racial/religious tensions and piss-poor handling of the pandemic in recent months you can see them trying to fight public opinion by attacking the media.
A big factor in this terrible wave of death in India was the resumption of public rallies for the elections. Hubris.
Comparing vulnerabilities is useful, but ultimately not that important. The real down-side of Windows are (a) its popularity, and (b) the fact that well-managed / secure was never its default configuration, so you depend more on competent sysadmins to use group policies, etc, sensibly to make it so.
You can find examples of Linux systems with default user/password that makes their security a joke, so the underlying OS details are only significant if you really have eliminated the other factors.
For Linux if you want higher user security you simply mount the user-writeable areas (typically /tmp and /home) on partitions as 'noexec' and then they can only use programs installed via the package manager. Which obviously they cannot use as you have not given them any administrative rights...
The satellites themselves will be much the same size, orbit around the moon probably a little lower but we shall see what they come up with. I suspect not *that* low as they won't want the same sort of constellations size that you see for Earth (~24 active satellites) navigation simply for the cost of putting it up there, and might be willing to accept areas of poor navigation coverage, etc.
You can say the same about Chrome now.
Some sites only work properly with it as the idiot designers don't test anything else, and it comes with Google's prying eyes screwing privacy as well. Not to mention Google using its near-monopoly ability to push through changes that no one really needs beyond Google's own agenda (idiot-brain things like
activeX USB and native file system access, for example).
Meet the new
bossbrowser, same as the old bossbrowser...
Is anyone actually able to explain why corporate networks and critical systems coexist on a network - beyond 'stupidity?
Money. Trying to save the cost of duplicated air-gapped/firewalled networks, or the time to manually check/reconcile things.
Stupidity and greed cover the vast majority of disasters.
The problem is the "average" driver includes a lot of serious asshattery by a few which greatly skews the results. If you as a responsible sober adult is going to swap control for a computer then you want it to be better than yourself by some measurable amount.
Think of how dumb the average voter is. Now remember half of them a dumber...
