Re: Nuclear power on the moon
@vtcodger & @ThatOne
Thanks guys. I wasn't sure if there was quite enough atmosphere on Mars for there to be any effective convection/heat dissipation.

Yes, unless they are planning on taking a nuclear power generator or a large number of solar panels, then it's not going to happen. Energy intensive processes require intense energy. The newer flexible and lighter solar power generating materials might be a good option. They could just be rolled out across the ground.
And just to top it off, we get fairly regular news reports that make the national media, of non-Tesla cars "mysteriously" self-accellerating into shop windows, shopping centres etc. and the driver never seems to understand what happened. People hit the wrong pedal all the time, or so it seems.
It's not beyond the bounds of possibility that these uncommanded accelerations attributed to Tesla software are actual and real events, but I find it very unlikely. Disclosure. I'm not a Tesla owner, have never driven one, can't afford one and still think the biggest mistake ever was to call the driver assist technology "autopilot".
"And that's before we get into the horrors of the personal tracking Starlink could be used for.. [1]"
You think people will be walking around with a sat dish on their heads so they can access Starlink on the move?
"The system will not compete with the Iridium satellite constellation, which is designed to link directly to handsets. Instead, it will be linked to flat user terminals the size of a pizza box, which will have phased array antennas and track the satellites. The terminals can be mounted anywhere, as long as they can see the sky"
"will soon burn up in the atmosphere contributing to high-level "climate change" gasses while also converting valuable resources to ash. Ash which the rest of us will eventually breath."
WTF are you wittering about? High level climate change gases for sats burning up on re-entry? The amount, if any, is negligible. And ash? Are you serious? Any one single active volcanic eruption will emit many, many orders of magnitude more of both ash and climate changing gases in a single day of activity than the entire human space program has ever done.
I'd not crow too much about achieving manned orbital capability. NASA already had that for 5 decades before they lost it down the back of the sofa.
It's great that it's happening, it's great that it's done with all the latest engineering and technology improvements. It's fantastic that SpaceX will be doing it with rockets that can land and be reused. But please don't act like it's a whole new innovation when it's something that should never have been "lost" in the first place.
On the other hand, if NASA hadn't lost the capability and had something on hand to take over from the shuttle, how might that system have evolved over the last 10 or so years? Would SpaceX exist? Or Blue Origin? We might still wondering if reusable space craft were possible. Now that I've put it into words, maybe cancelling shuttle with no ready replacement was the kickstart that was needed to get where we are today.
We are sad to announce that British Airways has gone into liquidation and no longer holds any assets. Unfortunately, that means the GDPR fine cannot be paid.
In other news, Brexit Airways would like announce it has acquired a huge number of assets at fire-sale prices and will commence operations immediately.

Someone owns the copyright to those images. It's not really all that different to taking a publicly broadcast TV show or film and making your own copy. It's a grey area if it's for personal use, but once you start either disseminating it or using it for commercial gain, then you on the wring side of the law in most jurisdictions, including the USA. The problem is that it's probably a civil matter and down to the copyright holder to try and enforce their rights. On the other hand, maybe the scale makes it criminal matter? IANAL so maybe someone can jump in and clarify.
"You can look at a picture. That does not give you the right to copy the picture and monetize it."
I wonder how many of those photos scraped up by Clearview are publicly published but owned by Hollywood stars and studios? I suspect it may time to buy some popcorn. As you say, it's one thing to look at a publicly published photo, it's quite another to make a copy and yet another thing then use that copy for commercial gain.
IIRC under UK anti-porn laws, having a digital copy is classed as "making".
"They already know who did it, they just don't want to admit how they know, so...blame Google..."
Isn't this already happening with the security services? Wasn't there cases where the FBI really didn't want to explain how they knew the accused did it such that they either got off, took lower charges and thus smaller sentence etc or had to find "alternative" evidence?
I once got sent to fix a printer at a Formule One "hotel". Now THAT was budget! The rooms had a metal tubeular framed bunk beds, double on the bottom and a single on top, a rail to put your own hangers on and a "table" with no proper top to rest a suitcase on. That was pretty much it. I can't remember if there a a TV or toilet in the room, but there no bath or shower. There was a shower room for every 6 or 8 room which was basically a large cupboard opened by your room key that "self cleaned" after you left.
Formule One are/were the very bottom end of Accor chain.
"Waitrose ...And lots of carrots and apples"
Do they sell the "rubbish" in large enough quantities for you? Would it not be cheaper and easier to get these at the local fruit and veg shop? Our local one always has a sack of apples marked as "horse feed". Or is only the best good enough for your horse :-)
"I'm easily amused by such things, but it remains one of the funniest things I've seen in my life"
I tried to read this out to my wife. She ended up reading it herself as I was too convulsed on the floor to get all the way through, having already read it to myself and knowing what was coming next! The three glasses of wine probably helped to bring out my inner teen.
"Given the light has to reflect off 3 not-intended-to-be-reflective surfaces, how powerful does the laser have to be? I get that the detector could be very sensitive but even that seems tricky. i.e. very sensitive to the laser return but not at all bothered by e.g. sunlight. But there is still going to be several orders of magnitude of loss which suggests that the laser output could well need to be eyesight threatening ..."
Yes, but it's an interesting first step. I remember watching Time Team and the various tools they used such as soil resistivity and ground penetrating radar evolve over the years. In those early stages the results were pretty crap, but useful. Later, better processing with faster CPUs and better algorithms massively improved the speed and quality of the results.
I suspect the hype about AI cars seeing around corners is just that. Hype. They have something new and clever and AI based self-driving cars is a good and current hook to hang it on for the required funding.
To an extent you are right, but being disingenuous with your statements. Chlorine washed chicken is not in and of itself a health hazard, but the reasons for doing it may well be. ie much of US chicken production is done in poor conditions such that they need to disinfect the chicken carcase to make it safe. It's partly an animal welfare issue, but also a case of unhygienic processing methods. Keeping the process "clean" throughout production is better for our health than relying on a single end-of-process disinfection.
"Northumbria independence is next.
Tek bak control, sithee"
I had a bit of a double take there, wondering why a Yorkshireman would be interested in Northumbria before I remembered those southerners down Yorkshire way are part of the Ancient Kingdom of Northumbria. As is Edinburgh of course, which will help put paid to the West Lothian Question once and for all.
"These days civil aviation has become a heavily standardised, say even industrialised process. passengers are squeezed and processed into flimsy flying tubes of aluminium wirh minimum levels of comfort and safety, in order for a chain of big corporations to achieve minimum costs and maximum profits."
It's also one of the metrics used in "greening" their carbon footprint, ie more people per ton of aircraft.
"We'll be ready to rehome ourselves when the greedy bastards decide to start turning the financial screws."
Why not just transition now? Put a holding page with redirect at .org. If you want you could even say why. If lots of small .orgs did this, it might even send a message. If enough do it, it might devalue the whole sell-off proposition or leave the new .org owners with a debt they can't pay.
"the public infrastructure thing is no different from everyone and every business."
Most business can't afford to pretend they are many smaller businesses paying huge amounts of licensing fees to off-shore companies registered in tax havens such that they turn over billions but make no taxable profits because they can't afford the lawyers to create find and take advantage of the tax loop holes.
"I suppose the proper thing to do would have been to change the engine mounts or move the wings farther forward, but doing that would have counted as a significant design change and necessitated a costly re-certification. Which is what they were trying to avoid."
I'm probably wrong here, but from what I've been reading, MCAS is only required because they wanted the aircraft to handle like previous models and so save costs on simulators and training. If proper simulators and training is intriduced and thus pilot certification on the 737-MAX, then MCAS wouldn't be needed at all. Can someone in the know confirm this or tell me I'm an idiot for suggesting it?
"I'll hazard a guess you're not a Brit. We make jokes about the grimmest of events - it seems to be a coping mechanism, and deeply rooted in our culture. It's not a sign of disrespect or dismissing the gravity of an awful event."
Correct. And it's much cheaper than having a therapist on speed-dial :-)
