By "here" do you mean "the internet"? Are you trying to discourage people from sharing their calculations and observations with one another if they don't personally interest you ? If so, what is wrong with you?

I wasn't suggesting using it for shipping boxes, but rather for things like robot arms.

"Plastic" is not a material; it's a property or state of many unrelated materials. It doesn't make any more sense to say that plastic is a risk to health than to say that liquid is a risk to health or that crystals are

Only if you do it in an oxidizing atmosphere. Though aluminum is very liberal about its definition of "oxidizing atmosphere".

It's not that my argument is flawed so much as that it depends on some basic background knowledge about processes like corrosion and solvation. Lacking that knowledge, you're better off taking my word for it that humans are not

That's SPIF ("single-point incremental forming"), which is mentioned in passing in my note: > These can presumably be removed, permitting traditional SPIF processing of raw foil by sliding the point over the foil; a bette

I'm not sure, but I think that normally it reacts with phosphate ions to form aluminum phosphate rather than leaving the body.

Also true of teflon, aluminum oxide, and Earth as a whole. Perfluorooctanoic acid, by contrast, is not mostly harmless.

You're welcome! It's a pretty broad term, with a lot of possibilities, but generally I mean a machine which, given a design for a machine in the form of digital data, can build a working machine of that design without further huma

I'm not sure, but I suspect cooling requirements also enter into consideration.

Oh, thanks! You are surely correct; I was puzzled about how something as relatively inert as pizza dough could corrode aluminum at multiple microns per hour, but electrolysis can definitely do that.

Aluminum is a major component of all soils, and soluble aluminum salts have been used in medicine and dyeing since ancient Greece, probably since ancient Egypt. They have been used in food preparation for at least several centuries.

Well, "Dercuano" sounds like "Dirk One Oh" in English, so clearly the sequel should be "Dirk Two Oh". And "Dernocua" is the properly formed vesre of cuaderno , unlike "Dercuano", which

It does not, but aluminum oxide is even more of a "forever chemical" than teflon is, though less so than, for example, the nitrogen that constitutes 78% of the atmosphere.

Let's see if this is a quantitatively plausible concern. https://en.wikipedia.org/wiki/Aluminium_chloride says orl-rat LD₅₀ of AlCl₃ is 380mg/kg, which is 20.2% aluminum by weight, so that's 77mg/kg

I do not currently have a sketch of a matter compiler, just a rough estimate that most of its parts count would probably be RAM, and that it probably needs several kilobytes of RAM.

Thanks! I keep unintentionally using https links to canonical.org since basically the whole web is https now. Fixed.

I wasn't expecting to see Dernocua at the top of HN today with 53 comments. You can download Dernocua as a whole from http://canonical.org/~kragen/dernocua/ if you're interested. I'm happy to answe

Maybe not for everybody, but I recall hearing that certain military units, students, and government officials were required to get covid vaccinations already in '20. Maybe he heard the same thing?

I have the same problem in Argentina. Worse, I'm pretty sure that Google and other search engines decide that I don't deserve to receive good information because I live in a Spanish-speaking country, so they send me to terrible l

The tweet immediately before this one says: > There's a weird disconnect in this vaccine mandate debate: many are still pretending that Covid-19 is of natural origin, which gives such mandates a different feel than they otherwise h

It seems that the "covid trutherism" or "spreading covid misinformation" claim is unjustified. Here's Blow's original tweet: > If a state entity does an oopsie in a lab, then forces its citizens to undergo

Linus Torvalds is effectively a full-time code reviewer, and so are most of his "lieutenants". It's not a new idea, as you say, but it works very well.

No, they did not. They made it free to download, but open-access† licensing would permit third parties to legally mirror it on servers that don't block access from Algeria or Switzerland or privacy-focused browsers, and so far that li

I think it had been many years since the FTP code had needed a security fix, and at least a year or two for the Gopher code. The entire original point of the WWW project was, approximately, providing a better user interface for accessing fi
