Now I have flash-backs to The Simpsons Barber Shop Quartet episode.

I knew NASA was broken back in 2004 when at the KSC tour they were still referencing the X-33 / VentureStar cancelled back in 2001. It's a perfect example of sincere individuals being employed by a make-work government programme.
On the other hand, I'm hardly enamoured by the corporate-welfare nonsense that has supported SpaceX et al down the years.
Maybe just as much as "Space is hard", "Funding Space is hard" should be the watch word.
Methane boiling point is 100 K, whilst for Hydrogen it's 20 K.
Explosion limits for Methane are 5% to 15%, whilst for Hydrogen it's 4% to 75%
Engineering tolerances are markedly different for the two fuels.
The real reason for Hydrogen's use is high energy per unit of mass and high specific impulse. Which sort of matters when you're heading to the moon.
At the time they were certainly "economical with the actualité" partly from institutional practice and partly because this was a nuclear weapons project.
Yes, unbelievably, the reactors were air-cooled, with the original design envisaging direct venting to the atmosphere. At a late stage, Director John Cockcroft insisted that high-performance filters were fitted on the chimneys, at some expense and initially referred to as "Cockcroft's Folly". They were clearly visible towards the top of the stacks.
The choice to have filters very likely made the 1957 disaster "not great, but not terrible". It is estimated they caught 95% of the particulate exhaust from the fire.
To quote Manchester University "Had they not been built, it is no exaggeration to suggest that a large part of the surrounding area – including the Lake District – might be inaccessible today. "
I left a well paid (but horrible) job for an opportunity that unwound after just 10 months. Pay took a bit of a hit for a year or two but absolutely no regrets and look back fondly on those 10 months + the subsequent gig I landed in a hurry.
I later left a lovely company that had nowhere for me to grow and leapt into another that had the right role. Loved it and though ultimately that ended in redundancy 5 years later, absolutely no regrets.
You've not got career experience until you're on the receiving end of redundancy. Be there for each other, wear your "Open to work" badge with pride and always, always play it forward.
I've lived long enough to see the products and great companies rise and fall and (very occasionally) rise again.
I've been a starry-eyed neophyte for everything from 32-bit (and then 64-bit) operating systems to handheld tablets, smartphones, virtualisation and 3-D printing. Lord, I've even given some credit to cloud computing benefits (though it's the thin end of the feudal wedge, in my opinion).
So I feel I carry some experience when I opine: Generative AI is a load of bollocks. Worse it's profligately wasteful of energy. And it's thirst for hardware has introduced a massive opportunity cost where RAM and GPUs are unavailable for actual innovative work. Any sane society would actually ban (or at least heavily regulate) it's use.
I run Teams and the Office 365 web apps OK* on my Linux desktop without worrying about WINE or Windows licensing.
Whilst there might have been a use case 20 or 30 years ago for Windows native apps on Linux, the Linux application estate is so extensive I have not felt any need to reach for WINE or other imperial entanglements.
[* "OK" being about as much credit as I'll give to anything from our friends from Redmond).]
A lot of things are a threat - or at any rate a balance of harms.
- Cooking and heating with dung or wood might give you lung cancer, but it beats raw meat and hypothermia
- Migrating across an ocean so that you can exercise your manifest destiny risks drowning and angry natives, but (according to some) it beats Anglican church services (well the new vicar can drone on)
- Getting a vaccination carries risks but it sure beats polio (ask FDR)
Now, AI. It risks polluting the water, ramping up the global temperature and impoverishing us all with higher utility bills. BUT it does give us the chance to generate generic meeting notes and six-fingered "digital art". AND it offers a novel way to further enrich that most benighted of demographics, the very wealthy.
It's true: as an example of successful multiculturalism Trump should study the Lancashire-Yorkshire dynamic:
- No Tarriffs
- No Borders
- Plenty of Muslims (and other faiths, and no faiths, and the better for it)
- Gorgeous scenery
- Ancient animosity consigned to a little bit of gentle ribbing about the dismal prospects of cricket/football/rugby teams
I think Balmer referring to Linux as "Cancer" has to be the point when MS realised how dangerous Linux was to their server OS business.
I mean, seriously Steve, at least SNAP! got a useful rhyme out of using the "C" word.
He might have lacked Charisma, Uniqueness, Nerve and Talent. But Balmer sure knew how to look like one.
Controversial, I am sure, but hear me out:
This was the pinnacle of MS-DOS.
Yes, future versions came out tied to the 9x products, but with built in utilities covering automation of memory management (MemMaker), disk compression (DblSpace, sorry DrvSpace), PC-to-PC file transfer (Interlnk) and an anti-virus engine (it was a nice idea), this felt like a fully evolved product. Albeit a technology cul-de-sac for 386 and above PCs.
Run Windows for Workgroups 3.11 on top of that and it was about as good as you could get in 1993.
Windows NT was definitely a better operating system. But everything that came after MS-DOS 6.x took away the personal aspect of personal computer and put the long arm of corporate policy on top of your desktop.
My Win11 corporate device was just off the other day after returning from a 10 minute tea break. Not "simple press of the button starts it up" nor even BSOD, but properly lights-out, hung and unresponsive*
[* I am aware, after typing, that "hung and unresponsive" has miles of comedy potential, so off you go, have that one on me]
I'll be honest it was my first year university lecturer (god rest his soul) who properly put me off fluid dynamics of the computational or any other kind. We used to call him Dr Death, because he was such a happy, cheery man. But I digress.
Yeah, Raspi is not really peak AI bullshit, as evidenced by their we're-definitely-not-nvidia share price.
Properly long term storage (of the order of thousands of years) is theoretically possible, and the Scandinavians are doing it. In the UK "kicking the can down the road" is a fair summary.
In the UK the first generation of nuclear power stations were designed to produce plutonium (for far less benevolent purposes), with power generation a nice side effect. We have been decommissioning these since the 1990s, so the process is at least established.
The second generation were to be a standard pattern, even sharing generator tech with contemporary coal-fired stations. In practice each reactor had differences from the other as experience of build and use dictated. They are also CO2 cooled, which in a nation that has a limited number of pure CO2 manufacturers might not be the best idea.
The third generation (just one, Sizewell B), is a more standard approach (internationally) but suffered from being built just as a certain part of Northern Ukraine embarked on a radical rewilding experiment.
The SMRs are supposed to be based on similar tech to that used in our nuclear submarines, where size is an obvious constraint. To the extent that we have experience in this domain, and folk who live months on end no more than a couple of dozen yards away from the reactor, I suppose it makes some sense. Within certain definitions of the word "sense".
Depends how you judge it, Seven.
A world-weary, slightly cynical riff on Britain's relative decline down the years will usually get you an upvote or two, especially if you reflect on past glories.
Nuclear power? Well us commentards are largely led by the evidence. The attitude to the last 70-odd years is generally "2 Level 7 incidents - not great, not terrible". But in my view all opinions are welcome. Even those Russian trolls I seem to attract.
I rather liked your tongue-in-cheek encouragement to have my country men take up Viagra (they did their bit in proving it's efficacy in the first place, after all). That said since my preference is for Cymraes rather than Cymro, I'm probably not the best person to opine.
