I'm in the same boat, except my first and last name are fairly common. My gmail account is not my primary email address, and to be honest I don't know if I could manage making it my primary because of the amount of rubbish I get.

I have a Garmin with a sapphire screen. I've worn it every day for over 5 years, working on cars, in the garden, snorkelling on coral reefs.

In short, I my watch has NOT had an easy life. I've made no attempt to protect it or taken it off for anything except charging. There is barely a mark on the screen. A sapphire screen will be a hard requirement for my next watch.

I wear mine while rock climbing. The watch has been put through a lot of beating against all kinds of rock. I've already chewed through 3 straps on this watch. The titanium case is lightly scratched, but the screen is absolutely pristine!

This is my second sapphire Garmin, and it's absolutely worth the premium.

Ever consider carrying a protein bar or two?

I feel that if you are in the target audience for this article (deep dive into the behavior and design decisions of the .net GC) then you probably know who Maoni is.

I'm just a sometime mid-level .net dev, and I immediately recognized her name.

That's fair, I usually read these .NET articles that crop up here on HN, though I don't always recognize the names, and I am easily the target audience, but I know industry architects who probably do not know who the author is offhand.

Yes, my 5 year old Garmin still lasts about 10 days. And thats with using GPS tracking + bluetooth audio for multiple recorded activities.

THANK YOU. I've seen the velocity of the space shuttle quoted as the speed that the foam had when it hit Columbia's wing so many times, and it bugs the crap out of me.

If that was the actual impact velocity of the foam, there would not be any doubt about whether the shuttle would survive reentry, that is if it even managed to make it all the way into space.

As the crew rose at 28,968 kilometres per hour the piece of foam collided with one of the tiles on the outer edge of the shuttle’s left wing.

This also cannot be correct at approx 82 seconds into flight.

I was thinking maybe this, but more likely X.AI would develop the models for Tesla, such as for FSD and Optimus.

Honestly, it might not be a bad move. X.AI has done some great stuff, Grok is rough around the edges but pretty much at the bleeding edge and it doesn't make a lot of sense for musk to be running two AI camps (Yes I know they are theoretically separate companies...(

I have read, but not verified the figures myself that if the United States had Australia's healthcare system - universal, government funded healthcare (excluding dental) then all US citizens would have near free healthcare, would not need costly insurance, and the government would spend a similar amount to what it does now

According to O3 US public health spending (state + federal) is 8.6% of gdp. For perspective, here's a list of countries with universal systems which spend less (these numbers include private spending), and life expectancy (US is 78.4 for reference):

  Singapore: 5.6%, 82.9
  Israel: 7.2%, 83.2
  Estonia: 6.9%, 78.5
  Poland: 6.7, 78.5
  Luxembourg: 5.7%, 83.4
  Czech Republic: 8.1%, 79.9

and a couple which spend a bit more, though again, this includes private spending:

  France: 11.9%, 82.9
  Japan: 11.5%, 84
  Portugal: 10.5%, 82.3
  Spain: 10.7%, 83.9

So it seems like we could have universal coverage and higher life expectancy if the US government simply spent exactly what it is currently spending, but on everyone, rather than just the old, poor, and veterans.

I think this is also a great chart showing health care expenditures per capita with life expectancy: https://ourworldindata.org/grapher/life-expectancy-vs-health...

Interesting to see countries like Spain and Italy, where the spend is one third of the US but the life expectancy is significantly higher.

There is a factor for the US effectively subsidizing these countries by having our current system. Healthcare companies make their bread in the US and get scraps elsewhere in the world.

This drives an enormous amount of innovation, and the near complete dominance of US healthcare companies in the west reflects that.

The US moving to a universal healthcare model would likely kill the lucrative US market, and while providing cheaper healthcare, it likely wouldn't make them dramatically cheaper while also having the effect of driving up costs in other western countries.

A bit like a balloon, where the profits are swelled in the US and limp elsewhere, squeezing the US will ha global effects.

Anyone that lives in a country with universal healthcare only knows it's a no-brainer because they have the American nightmare of a health care system to compare it to. Seriously, I don't know how/why Americans put up with the stress of one serious medical event potentially financially ruining your life.

Yeah I was going to say the same thing. Pandora's Star/Judas unchained is the best scifi I've ever read. Peter F Hamilton's worldbuilding is unmatched.

I agree. I've played a LOT of kerbal space program, and yes, this is just a game, with simplified physics, and a MUCH lower orbital velocity required. But the fundamental problems with an air-breating spaceplane are still demonstrated:

1) Orbital velocity is FAST. VERY fast. In KSP orbital velocity for a low orbit is about 2,200 m/s. For earth its about 7,600 m/s 2) An air-breathing engine, by definition can only be used inside the atmosphere. 3) You will struggle to get anywhere close to orbital velocity while still in the atmosphere, due to drag, and heating.

At best, your air-breathing engine will only get you to a small fraction (less than 1/4th) of orbital velocity. Then you will have to a) climb higher, and b) use a different engine to accelerate to the required orbital velocity.

Yes, you will potentially save some weight by not having to carry oxidizer for while you gain that first 1/4 or so of your final velocity. But once your air-breathing engines, and wings and everything else are useless, you still have to carry their weight
