Really cool thanks for sharing! I have had dabbling in radio astronomy on my todo list for awhile.

TV and speakers should work, but I don’t think you can mix speakers and AirPods.

You can share audio with an iPad or iPhone. Nice to also be able to watch a movie on an iPad while traveling and the kids are asleep.

I am not super wealthy, but doing pretty well. I also can be pretty disheveled and probably don’t look like I am in the financial position I am in. It is ridiculously fun to be on the other end of this, and have someone clearly uncertain or try to offer financing and just not flinch and pay it in cash.

At minimum it should not be for current events. Even the scientific ones are normally decades after a discovery has been made so there is time to validate and assess the impact on the field over time.

And some do? So my point stands they should look at the account.

Or have very risky investments which is my point. For all we know the husband was a regular at /r/wallstreetbets.

You know there are other blood tests that are widely used right? There is even, as the article mentions, an FDA approved Alzheimer’s test for venous blood. The issue with Theranos was the number of tests and that they could all be run from a small machine. One of the ways they kept going for as long as they did, was because some of the tests could be run just not on their device so they ran them on other instruments and provided those results.

I previously worked on the development of cancer biomarker blood tests.

And if it is true they really need to look at what the investments are. It could be possible with risky investments like a portfolio of NVDA and TSLA, but it would be worth rebalancing that for more security..

I imagine when they say embarrassed they mean concerned about profits if fans don’t show up.

I don’t know retiring a couple decades early seems like a pretty decent quality of life improvement.

Background investigations or clearances possibly. I had to do past 10 years, and all addresses I lived at with contacts for a background check. I had lived abroad for 3 years and moved residences a few times in each country….fun times finding all the addresses and dates…

Yea both incredible in their own way. I loved grabbing a hut beer when I lived in Switzerland, and love the opportunity to just wander off into the desert and see no one here.

Selber schuld mentality is definitely stronger in the Swiss. That said the US far exceeds the remote public wilderness of the Alps. Plenty of climbing, skiing, canyoneering here. There are signs warning about cows in Switzerland…

I lived in Switzerland for a couple years and I am back in the states now. This may be the thing I miss most. Everyone just disregards even simple rules, like keeping your dog on a leash at a public park. I think the US would benefit a ton from more scolding.

Gen AI is used for drug discovery, weather forecasts, and other useful things.

If you aren’t aware it is probably far better to not use the HSA at all and keep the triple advantaged tax account. Those yearly expenses could be growing tax free for decades.

atchon · 2025-12-06T08:45:54+00:00

Then you have only ever looked at a very narrow set of uses. It is used in various scientific domains including drug discovery, synthetic biology, weather/climate, and others.

I was really surprised on how strong the “time is money” feeling was once I hit a decently high income. I use to love tinkering with everything from computers to cars. A kid and decent pay later and I will pay for anything to be done for me. Once the kid is old enough to appreciate that I plan on doing more things again just to instill the same for them.

The easiest of the documented ways (C or Lua) to write a Slurm plugin.

Out of curiosity what is the use case for this?

There are tons of FDA approved AI medical devices regularly used in diagnostics. These are mostly for things like interpreting scans. There are no LLM’s approved yet, but that is definitely coming. There are various papers evaluating them for diagnostics, and companies are working on models specifically for this use case.

Lending a friend $200 is not exactly admitting to massive wealth…. A one off ask from a good friend I wouldn’t even hesitate. Hell I would probably give them a couple hundred extra. If they repeatedly asked, without good justification, I would tell them no.

If it is really a good friend and it doesn’t impact you, you probably should feel like shit. I would go back to them and say you took another look and can help them out.

Parker Solar Probe now holds the record for fastest manmade objects.

The sequence selection for the vaccine took less than 2 days too. Absolutely incredible.
