Ask HN: Is there a credible gut health test out there?

I've been shopping around for a gut health test / biome test, for both me and my partner (adults), as well as for our young child. It seems pretty hard to understand which company provides a serious, credible service, and which one is simply good at marketing. Is anyone able to provide some guidance on the topic?

Ask HN: Do you also feel that it's impossible to keep up with AI?

I have a tech background, I haven't been super active in coding or other things, but I still play with stuff a lot. And yet, in the past ~2 years, I often feel that it's pretty much impossible to keep up with the latest AI development (in particular regarding vibe coding), which in turns gives me less energy or determination to explore the latest thing. How do you feel about it? And did you...

Re:Gold is now the top U.S. export on Sunday October 18, 2026 @10:01AM (#50141176)
It's a long story, but Italy's gold is not really Italy's, in the normal sense. Italy lost WWII, and has been a de facto "vassal" of the US since then; the US has several military bases in Italy, and has a very strong influence on anything related to foreign policy, etc. Don't take my word for it, there's not a single link to prove this, but a bit of research should make what I say at least plausible.

Just to give a small hint: the 1998 "strage del Cermis" [0], in which a US aircraft mistakenly cut a cable supporting a cable car and resulted in the killing of 20 people. The pilot, Captain Richard J. Ashby, and his navigator, Captain Joseph Schweitzer, were put on trial in the United States and were found not guilty.

Try to imagine something different. An Italian military aircraft flies in the US, and mistakenly kills 20 people. What would have happened to the Italian pilot?

It is possible that they might have licensed some of these patents. Either directly, or through a shell company to hide that it was for Tesla.

Very impressive prototype. Certainly an attempt to disrupt a specific segment of the car industry - "race cars", or "sports cars", or whatever you want to call it.

A few considerations, just my own thoughts.

1) I would bet that the actual car shown in the demo weights less than what will eventually be sold to the public. I am not an expert, but the way in which the car reacted to the air boosts suggests a relatively "lightweight" vehicle. Plus, I would imagine perhaps a smaller battery (again, for demo purposes).

2) It is a nice "exercise" as a game, or an expensive hobby for billionaires. I doubt, as Elon hinted, that using these thrusters will be allowed on public roads. Perhaps just on circuits?

3) Overall, Elon said that Tesla's strategy will no longer be about cars, but about robots and AI, and then proceeds to show a car that will cost billions to develop, and might not be the commercial success that justifies the investment.

4) Twitter (now X), Tesla, SpaceX... things are moving, tricks are being shown, and who knows, perhaps next year everything will be merged under ElonX, and he will finally be happy.

> when it weighs 1.5 tons.

Are you referring to the Tesla Roadster? Because, if not, I am pretty sure that most EVs, except for maybe small compact EV cars, usually weights 2 tons or more.

Hmm, without googling: I'd guess something like Stellaris, given how popular it is? (never played it, but I'm a fan of the genre)

I am pretty sure it is not from Sid Meier's Alpha Centauri.
