tape_measure··on When Kitty Litter Caused a Nuclear Catastrophe
I'm submitting this based on the current top item "North Dakota law lists fake critical minerals based on coal lawyers' names" [0].

This accident was traced to a manager transcribing "inorganic absorbent" as "an organic absorbent". A more serious example of the need to have competent people with domain knowledge in the room and empowered when documents are written.

In fact, your comment is a factoid (in your meaning or the other replies' interpretation)
tape_measure··on GPT-5 leaked system prompt?
WORDS IN CAPS are different tokens than lowercase, so maybe the lowercase tokens tie into more trained parts of the manifold.
tape_measure··on Starlink Gets FAA Contract
Interesting how the article only quotes part of the statement, leaving out "the FAA has been considering the use of Starlink since the prior administration to increase reliability at remote sites, including in Alaska".
tape_measure··on History of CAD – David Weisberg
I'll have to work through the 650 pages.

I use CATIA v5 every day, first released in 1998. It's sharp and crusty and huge, but does everything (with the right license).

3 guesses! It would be fun to have other properties like melting point as hints.

tape_measure··on US Trademark Office Cancels Marvel, DC's 'Super Hero' Marks
Interesting points from https://fingfx.thomsonreuters.com/gfx/legaldocs/myvmamnnavr/...

5. In 1980—decades after the birth of super heroes—DC and Marvel jointly registered SUPER HEROES as a trademark.

6. DC and Marvel claim that no one can use the term SUPER HERO (or superhero, super-hero, or any other version of the term) without their permission. DC and Marvel are wrong. Trademark law does not permit companies to claim ownership over an entire genre. SUPER HERO is a generic term that should not be protected as a trademark.

7. Trademark law also does not allow competitors to claim joint ownership over a single mark. The purpose of a trademark is to identify a single source of goods and services.

20. DC has accused Superbabies of infringing DC’s “SUPER”-related trademarks, has filed an opposition to Superbabies’ trademark applications (TTAB Trademark Opposition No. 91290757), and has threatened further legal action. DC has asserted the exclusive right to use “the prefix SUPER followed by a generic term for a human being."

There's also some examples of SUPER HERO used as a generic term by DC and Marvel. I know of some companies being famously strict about trademark use (example https://www.velcro.com/original-thinking/the-velcro-brand-tr...), and yet these uses seem benign. For example, a splash at the top of a comic book "DCs BOLDEST new super-hero" (without TM, with dash). Now I have to be careful about using any of my company's trademarks. I'm not sure I fully understand how this example is generic and harmful.

This is AI generated slop. Please remove.
tape_measure··on Ask HN: Any hardware startups here?
I'm very interested in anything else you can share about the corrosion problem you solved. Wet, hot ammonia must be awful.

I like Jira. I'm not a SWE, different kind of engineer.
tape_measure··on Burning Kelp for War
Metal carbonates are generally not considered organic.
tape_measure··on Burning Kelp for War
"... potash, an organic compound..." - immediate Gell-Mann amnesia effect. Potash is the soluble, inorganic leftovers of burnt plant matter.

What's interesting is how many different names derive from this production method. - potassium from "potash" (pot ash, collected burnt stuff) - K from "kalium", related to calcine (burn to ashes) - Alkali for basic compounds, which nearly all soluble metal oxides are - Calcium and Ca also derive from this root

(now let me check all of this so I don't Gell-Mann myself)

The terms anode and cathode are reversed. Mnemonic device:

Cathode - cats - good - positive

Can you recommend some other Xometry/Hubs competitors for hobby use?
tape_measure··on Benzene detected in many sunscreen products
I can't tell if this is sarcasm. Anyway, I think my exposure to gasoline is higher than to sunscreen.
tape_measure··on Ask HN: Desperately need “sales for nerds” advice
Yes, I suppose having a concentration of hydroxide is good to keep the carbonate from reacting and bursting the packaging.
tape_measure··on Ask HN: Desperately need “sales for nerds” advice
Why does the Chalk Cream have sodium hydroxide in the ingredients?
