Neutron star cores are superconductors even at a temperature of a few billion degrees (temperature defn get a bit squirly in a neutron star core) however the pressure is also a little extreme

Good news: Boffins have finally built room-temperature superconductors. Bad news: You'll need a laser, a diamond anvil, and a lot of pressure
Re: Did I miss it..
Nope its only magic while being pressed.
And we don't know what its limit magnetic field is
And it's probably really hard to make into long wires
And it probably wouldn't have the right pinch point properties to self-recover from a quench
Temperature isn't the hardest thing about superconductors. If you had all the other properties right then even liquid nitrogen "high temperature" superconductors would be practical.

Re: Sympathy with investors is limited
There is a difference though between being over-ambitious and a down-right con.
If in 1976 I tried to get you to invest in a circuit board that you could type things into and it would run programs and produce results you might be sceptical that this PC thing would ever catch on or that the market would justify the cost.
If it turns out that microprocessors don't exist and there is a hidden wire to a teletype in another room where a team of people are working out the sums on paper and typing the answers = that's a con.
Re: Technology
That's not unreasonable, it's just an engineering problem = you raise money to hire people to solve it.
It's like saying building the infrastructure to make a car to run on batteries is too much for the two guys that started Tesla and so it was a scam.
What the experts did say is that blood isn't perfectly mixed so taking a 0.1ml sample to reliably test for all the diseases they claimed wasn't going to work - because that 0.1ml might contain no markers for disease X even if you have it.
I can invent a much more sensitive soil test for a mineral, but if I then claim that I can find gold anywhere in the world from a single shovel full of my back garden - it's likely a con.

Re: Britain solved this 'tech problem'
The problem with the British system is that anybody is allowed to vote.
By adding extra security measures, like having mandatory voter registration in Latin at the top of a mountain accessible only by Range Rover one can ensure that the peasants who watch Mrs Browns Boys don't interfere with the electoral process
Contract to run .eu domain-name registry is up for grabs as Brussels tries to avoid a .co-style debacle
Except if you do it for a business that generates almost no revenue (on the scale of internet companies) and has increasingly complex bureaucratic requirements, you end up with one incumbent who has the past experience to tick all the boxes and the 'contacts' in the bidding process - and they get to charge what they want.

Re: "a kind of punishment on the UK government"
In response we are banning them from using English - that'll teach the blighters.
To be slightly more serious. People who us .eu are still paying the "golf club" to use it and are likely to be pro-eu. This is rather like the WHO saying: "if the US government leaves we aren't going to accept any donations in US $"

IT Marie Kondo asks: Does this noisy PC spark joy? Alas, no. So under the desk it goes
Re: cold feet warm computer.
During a few years in sunny climes I had an office that was freezing.
As in - I'm wearing a hoody at my desk and there are palm trees outside my window - freezing.
I complained and was fobbed off with, "you Brits have probably never seen Air Conditioning before".
Tried blocking the outlet vents and fiddling with the thermostat - risky activity with university facilities people.
Later heard that my replacement had also complained and discovered all the AC airflow valves had been put in the wrong way round. the more the AC tried to warm the room the colder it got.

It really is your last chance to see anything at Cineworld for quite some time, and this big-screen bork speaks volumes
Re: Cinemas in their current form are an artefact of the limited availability of reels of film
>But the flip side of course is that cinema's in general have been ripping people off for decades.
The cinema gets almost none of that ticket price.
The opening weekend ( which actually means a week) ALL of the ticket price goes to the studio
In subsequent weeks the proportion going to the screen increases.
But the profit is entirely made on snacks/drinks and booking fees.
FFS FSF, you're 35 already? Hands up if you just sprouted a gray hair or felt a craving for a Werthers Original on reading that. Happy birthday, folks
Re: Stallman's absence
IANAL but the main purpose of GPL3 isn't to prevent blobs - it was to prevent somebody taking opensource code and using it in a product but locking it in such a way that you couldn't make changes.
On the other point I agree that there should be MIT/BSD alongside GPL. Some important libraries I work on are popular because they aren't GPL and so can be used without getting corporate lawyers in a state.
But I can see the point of having a "true believer" pushing for extreme freedom - if only to drag the others along. I suspect if all open source was BSD/MIT there would be a lot of internal corporate forks and very little sharing.
Excel Hell: It's not just blame for pandemic pandemonium being spread between the sheets
Re: Relax...
> almost all the actual uses of Excel in practice are as a simple spreadsheet
Almost all actual uses of Excel are as an ETL (extract-transform-load) tool.
ie to download information from one app, reformat/reorganise it and send it to some other app - and it's extraordinarily bad at this - in ways that most users don't know.
Hence all the genes misclassified as dates, dropped initial zeros in phone numbers, bad handling of embedded commas etc
Meet the new aviation insecurity, same as the old aviation insecurity: Next-gen ACAS X just as vulnerable to spoofing as its predecessor
Re: real weaknesses of ACAS
There was a crash where one crew obeyed the ACAS and the other obeyed ATC. This has now been settled = if you get close enough for ACAS then ATC has screwed up so ignore them.
One concern is that the cybersecurity requirements get to be too strict. You don't want to ignore a jet coming straight at you because their certificate expired at midnight.
Wind and quite a bit of fog shroud Boris Johnson's energy vision for the UK
Great opportunity
Pay £160m for some Siemens turbines = making a £160m investment in green tech.
Load them onto a ship in Belfast, making a £160m investment in NI and a £160m investment in repurposing old shipyards.
Then install them in the Irish sea making a £160m investment near a former industrial area and brining the power ashore in cumbria making an investment in the rural North West.
Delivering £160m of green power.
So for only £160m you get £bn of green!

Hydrogen-powered train tested on Britain's railway tracks as diesel alternative
Re: Not as green as 25kv overhead
>Natural gas is hydrogen bonded to carbon
Obvious solution is to combine the hydrogen with carbon = green carbon capture tech
Then distribute the resulting methane safely by pipeline into tanks on the train = simple existing technology
Use solar, wind or reliable nuclear electricity sent over low-loss 25KV overhead lines to split the methane into carbon and hydrogen. the hydrogen can then be fed to the fuel cell.
A future Britain could then develop some technology to allow trains to be powered by the waste carbon byproduct
