They used TTL 7400 devices on Voyager. Bomb proof and easy to design.

Systems not connected to the iternet dont need an upgrade. I have seen POS and travel announcment systems running XP!. They work well. Why fix it when it is not boken? I upgraded to W10 a while back and my Webcam, scanner and printer stopped working because they had no W10 dtivers.
"The Large Hadron Collider (LHC) uses roughly 0.65 terawatt-hours (TWh) of electricity annually, which accounts for about half of CERN's total yearly consumption. This is equivalent to the power needed to supply roughly 115,000 to 150,000 homes for an entire year" (Google).. So CERN total consumption is equivelent to powering 300,000 homes a year. That quite a lot.
Its been there for a long time. Three years ago I had the same problem looking for driving tests for my wife. I got locked out and could only get in using Firefox Incognito. The reason I was given was that I was navigating the site to fast using an old Toshiba laptop and copper connected internet. What do they expect people to use, tin cans and a length of string? Now theres a project to occupy idle hands.
You are correct, Titanium & it's alloys are paramagnetic. Howver, rocks containing Titanium minerals can be magnetic.
The primary magnetic titanium mineral is ilmenite which is weakly magnetic. Other magnetic titanium-bearing minerals include titanomagnetite, which is strongly magnetic due to high iron-titanium oxide content.
It is strange that the researchers mentioned Titanium but not iron.
This digital ID thing is a bit flakey at the least. I tried to renew my driving licence recently and having gone through all the hoops and hurdles of the GOV.UK One Login app used to get to the DVLA section something stalled with the response "inadequte security information". I tried a few times, sent a message off to the right people and was told that the "inadequte security information".was at their end. I have had bank accounts, building society accounts, NHS, tax etc for decades but for some reason that was not enough. They sent me a link for the old DVLA online application form. This link was not visible on the new site. The link worked, the old form worked and a new licence arrived by post on time. I suspect this may happen with other GOV.UK One Logins.
I complained and the response was that security checking was done by a third party and GOV.UK is not responsible for it.
iProov performs the "liveness" check (ensuring you are a real person) and "likeness" check (matching your selfie to your ID document).
iProov uses subcontractors Veriff and Inverid to assist with these checks.
Ther is probably more to it than that.
If a machine is not connected to the internet and has no Wi-Fi connection there are few security concerns. If it works well dont replace it. I have seen stand alone point of sale (POS) systems running Windows 7 and they work well. They were very expensive new and very expensive to replace. Even upgrading the OS would be pointless. Most of the POS peripherals dont even have drivers for W10.
The question of what is the effect of extra weight is easily calculated. I used Google AI to do the calculation. The results are surprising and tie up with the statistics.
How much energy is transferred to a 100kg mass when struck by a 2000kg mass traveling at 30km/h? The amount of energy transferred to the 100 kg mass, assuming a perfectly elastic collision, is approximately 12,598 J (Joules).
How much energy is transferred to a 100kg mass when struck by a 1000kg mass traveling at 30km/h?Assuming the 100kg mass is initially at rest and the collision is perfectly elastic, approximately 11478.42 J (or 11.5 kJ) of energy is transferred to the 100kg mass.
Even being by a ten ton truck is only a bit worse. The energy transferred to the 100kg mass is approximately 13615.22 J.
An elastic collision is one in which the objects after impact become stuck together and move with a common velocity. Thats a bad pedestrian crash. In all three cases the collision is probably fatal. Crumple zones help reduce the damage.
My apologies for using Google AI for every calculation.
I needed to replace a driving licence online. The multiple "prove your ID" loops were endless. I contacted GOV.UK One describing the problem and was told there was insufficient information held to confirm my ID. I have held many UK passports. Five in row. I have current bank accounts dating back decades but the explanation was that the ID verification was done by a third party who did not have enough data. I was eventually given a link to the old DVLA online lycence form, that worked OK. I have a very bad feeling about these new online services.
This digital ID is linked with GOV.UK One Login. Have a go at setting up your ID and using it on a GOV.UK site. I needed to replace a driving licence online.

Attacks on the NHS, car manufacturers, supermarkets, brewers etc suggest that these attacks are becomong more focused. What next? Critical government systems, defence systems all are vulnerable. I have this dream of a hack that deposits millions into the bank accounts of every person in the world. Wont happen, hackers are not that nice.
Your right there. Apparently sterilzed sealed comtainers full of sterilized nutrients can be left for a very long time without showing any signs of life. Nicolas Appert's and Louis Pasteur foumd this out a long time ago. If the planet Earth was completly sterilized it would stay like until seeded by life from outside.
The same for many other things, sometimes the time scales are even shorter. Li-ion battery performance increases are a good example. The optimism of some researchers seems to be boundless. I cant even spell "optimism" without using a spell checker.
The randomness you are describing is impressive but is well known. In order to publish, novel ways of doing things need to be found. People will carry on inventing new ways of generating random numbers. I was going to say forever or until the cows come home but could not find a suitable epithet.
They are going to recruit the wrong people. I did a GCHQ recruitment interveiw and the test revolved around scheduling a bus timetable. My ability to code and decode had no impact. I went all the way to Cheltenham and back paid by the government and felt that I was not the one that lost out.
