Reading the other day about the time an A12 pilot used his undercarriage as air brakes to slow down from full speed.
The full speed of an A12 (codename Oxcart) was Mach 3.2. The plane was later developed into the more famous SR71 Blackbird.
Apparently the Lockheed engineer in the debrief room, on being told, snapped his pencil in surprise.
The pilot said it was “very loud”. I bet it was!

@Christine Burns MBE 🏳️⚧️📚⧖ it would induce a pitch-down tendency for sure, but nowhere near as much as water. It’s still moving through the same fluid as the rest of the plane at this point: the air. All it does is lower the centre of drag (and increase it massively), but the aircraft would easily be able to counter it.
Not a massive amount of stress on the wheels too. Mach 3.2 is fast as hell, but it’s at 80,000 feet and the air pressure up there is tiny. Someone calculated that it’s like doing 330 knots at sea level. That would be deeply unpleasant and probably cause significant injuries to a human, but the plane would be just fine. It’s just utterly wrecking the aerodynamics.
Vitamin D3 pills are literally HRT.
If you live north of 35ºN, you should probably be taking them right now.
That's it. That's the post.

I get that D3 is a pre-hormone, not a vitamin. And that deficiency can be disastrous. But when you call it "HRT", are you implying it supports feminizing hormone activity?
Do you have any confirming documents? I've seen a bunch of conflicting research done on knockout mice with severe E deficiency, but nothing relevant to healthy humans...
@LorenAmelang It’s a hormone, that you replace, hence hormone replacement therapy.
This is not a trans thing.
Random thoughts: it’s funny what you think is important.
When I was younger, I wondered about who people credit with investing the incandescent light bulb. Many people will say Thomas Edison, others will say Joseph Swan, and others from outside the angliosphere may give yet another answer.
But ISTM now that it’s a really weird thing to focus on. The light bulb was obvious. Its invention is trivial, and the fact that several people did it simultaneously should tell us that. It wasn’t a great breakthrough. Everyone knew wire glowed when it got hot. The problem in using it for light was that it burned.
It’s not the invention of the light bulb that’s important. It’s the invention of the vacuum pump.

@FediThing @stevelord the marginal cost between a trolley electric and pit-stop-charging bus battery will be negligable - electric double deck bus costs £450K, (diesel is £300K) says google, for reference. More google says £200 per kilowatt hour, big 300kwhr battery is £70K, so you'd save maybe 50K per bus
Overhead line gear is in the millions per km on a good day... and then you have to *still buy a bus*.
Or buy 4 or 5 go anywhere buses
Wires for trams great. Buses, nah

@FediThing @Kincaid @Steve Lord As I said, were I investing in this, I would not bet against battery tech. That’s a sucker bet.
The problem with covering cities in metal string for trolley buses is not a technical one. We know how to do it. We’ve known how to do it for over a century. Technically it’s a solved problem.
The problem is social and logístical.
It’s entirely possible, of course, that trolley buses are the right horse to back, in the same way that it’s entirely possible that everyone in between me and the throne of England will die tomorrow and leave me to inherit it.
It’s not gonna happen through.

@benofbrown They’ve found a line that keeps the press off their backs, for now. They’ll stick to it.
The only things that might meaningfully change things:
1. Scottish Government defend GRR, and lines soften on self ID in England over time
2. A major win for or against trans rights in court changes the ball game (which paved the way for the Gender Recognition Act in 2004)
3. Hung parliament forcing Labour into coalition
4. Tories lose so badly they even lose the Official Opposition.
Ah, people on social media being knobs about the orcas again. Apparently they are “trying to send a message to humanity” by ripping the rudders off the boats of middle class people pottering about on what are basically floating caravans.
Fine, if you’re gonna anthropomorphise the murderfish, I’m gonna do the same and suggest that, given the attacks are being carried out by adolescent males, the message is, “nice boat, be a shame if anything happened to it. Now toss some tuna and dolphin hentai overboard.”

Guys, if you live outside the tropics, consider supplementing your D3 levels.

Tip for well-meaning people doing diversity monitoring: if your form expects trans women to, at any point, tick anything that says “male”, then that is profoundly offensive and most of us will just lie to you.

@mercedesallen I’m sort of hoping this - the whole counterrevolution against any process made since the 60s - is all an extinction spike, like the anti abortion referendum in Ireland in the 1980s.

Increasingly getting the impression that MacOS Sonoma is a lemon, and best avoided.
Interestingly, when it bricked my M1 Pro MBP, and I had to recover from the recovery partition, it reinstalled Ventura.
And the new Macs ship with Ventura, with no Sonoma upgrade available.
Now seeing that the 14.1 update has screwed a load of webcam stuff used by remote workers.
I think I'm gonna keep my MBP on Ventura for now. My Mac mini server is on Sonoma, but all that's doing is hosting Linux VMs.
@Miguel Arroz That sounds profoundly buggered indeed.
Touchwood I’m ok. The 6 days uptime is because of a power outage 6 days ago.
Every so often I encounter someone who is very stridently advocating for understanding and sympathy for narcissists, to the point of sacrificing yourself to give them what they crave: supply.
And every time I smile, nod, and then instantly file them in the same mental drawer as “psychotic tiger in a bad mood”.
Never believe their bullshit, ever.

@Llwynog yeah. Once you’re wise to their shit, you can defend yourself.
But if you don’t understand, and they’re in a position of power over you, that’s when they can do profound damage. A lot of us who were raised by them evolve coping strategies, but when you’re a kid having to defend yourself against the person who is supposed to be nurturing you, it causes life long damage.
We also tend to be on high alert for them, constantly. If someone behaves in a way that triggers my narcissist response, it’s instant fight or flight, with a heavy dose of grey rocking.
This has actually served me quite well, but it’s a fucked up superpower to have.
the endless guilt-tripping is their most powerful tool. Covert Ns are really insidious because they present themselves as shy, introverted, morally superior and even sweet, initially. They're masters at mental gymnastics.
Playing the victim, endlessly talking about themselves and constantly complaining are my three N red flags.
Do you have any advice on how to detect (covert) Ns before they can do much harm? Any specific behaviours to watch out for?

So it seems there are still, despite increasing numbers of “leaders” involved in “crypto” ending up in prison for being con artists, true believers in NFTs (if you’ve forgotten about those, they were briefly bigger than COVID 19 and about as beneficial to humanity) held a party in Hong Kong last night.
The organisers thought they were lighting the stage with black lights (like they have at LaserQuest to make your clothes glow).
They were not.
They were lighting the stage with UV-C sterilisation lights.
Apparently everyone involved is now in accident and emergency with extensive sunburn and BURNS TO THEIR RETINAS!!
In 18 months there are going to be a bunch of people wearing dark sunglasses and refusing to meet outdoors trying to sell you something expensive to do with “AI”. You probably shouldn’t buy it.
