Nick87633··on X-Plane 12 Flight Model Update – Supersonic Transition, Delta Wings and Mass
It forms a single vortex over each wing, coefficient of lift still increases with angle of attack. It's more like moving the wingtip vortex near to the nose of the plane. There is a much higher 'true stall' angle of attack where flow separates and lift reduces.
Nick87633··on A single prophylactic 200mg dose of Doxycyline prevents Lyme disease
That's awful. I did a two week course but had no adverse effects.
Nick87633··on Price shocks in formative years scar consumption for life
They still had installment plans for buying appliances and repossessions. I'm pretty sure usurious loans have existed since money was invented.

My wife and I have had some fun games of German whist

I'm from Illinois and euchre was popular at summer camps in the Midwest when I was attending in the early oughts

Up to $10k per person (more with certain workarounds) with other limitations.

Nick87633··on Report: 90% of nurses considering leaving the profession in the next year
You're right too. Their former glory is gone, I never knew how much bigger they were before until I looked up more of their history today.
Nick87633··on Ask HN: Teach me something new
I've definitely felt this before, The hot soup, hot tea, sweatpants, sweatshirt, wool hat, get-in-bed I feel like I'm about to have a fever reflex.
Nick87633··on Ask HN: Teach me something new
Feels like a good VR experience or magic school bus episode would help solidify this! Or maybe time for this adult to make some dioramas.

Tektronix didn't go bust. It was acquired for $2.8b in 2007 with 4,000 employees and is now part of an umbrella corporation that trades as NYSE:FTV.

Their scopes are still for sale and still good.

Nick87633··on The “fifth wheel” parallel parking tool that never hit it big (2018)
You would love the Brabham BT46B then.
Nick87633··on The “fifth wheel” parallel parking tool that never hit it big (2018)
The 4-wheel steering on modern cars is typically to help with low speed turning circle size on longer wheelbase cars, not really for high-speed performance although they do put it to use at high speeds for some marginal benefits.
Nick87633··on Europe is investing heavily in trains
Just because the tank is light, doesn't mean that a completed fuel carriage will be much lighter than any other car.
Nick87633··on How did the Victorians become a reference point for joyless prudery?
Because of the Protestant foundations of our country.
Nick87633··on How did the Victorians become a reference point for joyless prudery?
The protestant puritan history is probably where the reputation for prudery comes from. The Roman Catholics knew how to party, buying indulgences to forgive sins and continuing to celebrate roman festivals under the guise of Catholic holidays. The Protestant Puritans wanted to put an end to these festivals as well as marriage festivals and funeral traditions. They accomplished this in England with the 1642 Directory for the Public Worship of God based on puritan ideas. Since the festivals were not prescribed by the bible, they were to be replaced with Bible study and prayer. During the Interrugnum from 1649 to 1660 England was basically under Cromwell's puritanical military dictatorship until the Restoration of the effectively Catholic monarchy, which restored and soon increased religious freedoms.
Nick87633··on New connections between circadian rhythm and muscle repair
These monkeys showed higher nocturnal locomotion and reduced sleep, which was further exacerbated by a constant light regimen.

This sounds like borderline torture

Nick87633··on Cool ice formations my friend discovered on his deck this morning
Almost certainly not.
Nick87633··on NASA says Webb’s excess fuel likely to extend its lifetime expectations
Yes it does exactly this. It uses reaction wheels (circular counterweights) for rotation generally, but when they can no longer spin faster it will have to use propellant to adjust its angular momentum back to zero.

In addition, it uses propellant for orbit position keeping (station keeping) as you wrote.

Leftovers are the best. Home cooked food without the hassle!

Dec 22, several minutes of terror followed by ~33 days of nail biting until the majority of deployment is complete
Nick87633··on Aviation Safety Whistleblower Report on 737 Max [pdf]
This sounds like a normal test engineering position if the operation of the test and preparation of test article has been delegated to that team. Engineers should be empowered to work honestly and tell their company if a test has been failed.
Nick87633··on A key inflation measure rose to a 39-year high last month
There is a lot of chaff but I find it here on HN, reddit (personal finance, investing, wall street bets, quality convos in other random subs), and a limited number of posters on Twitter (probably my least favorite place, bleh).
Nick87633··on Common Jobs in a Medieval City
Sounds like a wholesaler/retailer arrangement.
Nick87633··on An eccentric monk’s singular scrap cathedral
Of course, the fire marshal caused it to be closed to the public. Bureaucrats can't stand anyone having fun.
Nick87633··on Japan’s curiously quiescent inflation rate
Seems like velocity of money theory doesn't take into account that the rich and poor (and businesses) have different spending or investing habits.

In my opinion the velocity of money for consumer and retail products is more or less constant because a large portion of the population doesn't (or can't) save a significant percentage of their income, while the 'asset money' category like real estate and stock market is hugely affected by velocity of money driven by falling interest rates.

Nick87633··on Japan’s curiously quiescent inflation rate
Yeah! Exactly! Just him, Alan Blinder, Paul Volker, and countless PhD economists like Aurélien Goutsmedt.
Nick87633··on Show HN: I built a CNC-machine from scratch, using 40x 3D-printed parts
Or a center punch (helps on flat metal too).

One favorite trick of mine is to print out 1:1 drill pattern drawings and center-punch through the paper onto my metal workpiece for all the drill locations. Fast and accurate.

Nick87633··on Boeing says certain 787 parts improperly manufactured
Maybe they wanted the lower CTE and higher fatigue resistance of the titanium, and one fewer process step to qualify and control (the anodization).
Nick87633··on Best performing assets against inflation
Lost me at lemonade stand "capital expenditure" being lemons... that's COGS, not capital.
