Guessing you like your espresso bitter?

“Saving up to 75% of energy by not heating the water is a minor benefit for home users or small coffee shops. But for companies making ready-to-drink coffee products at industrial scale…”

The instant and dried coffee market is $35B-$50B. Cold Brew another $3B-$4B.

If the opening illustration catches your fancy, Goodsell's book "The Machinery of Life" may be a good buy. https://ccsb.scripps.edu/goodsell/machinery-of-life/

Interesting, cool to hear that it wasn't all bluster. So now I must know... how's that blender?

Not by any means a Jibo replacement, but Peeqo may be of interest for some of the social aspects. https://peeqo.com

I almost backed the Coolest Cooler, until I saw the built-in 'ice blender' and realized I didn't want a cooler that required a power supply. Sad to see so many people get taken for a ride :/

As long as Peloton steers clear of building any yogurt factories in Ohio, I'm all for it.

Anyone else find the claim that "This was not human research" as erroneous as I do?

New comment by davidkuhta in "How many x86 instructions are there? (2016)"

davidkuhta — Wed, 21 Apr 2021 15:29:25 +0000

> To not leave you hanging: Intel has an official x86 encoder/decoder library called XED. According to Intel’s XED, as of this writing, there are 1503 defined x86 instructions (“iclasses” in XED lingo), from AAA to XTEST (this includes AMD-specific extensions too, by the way). Straightforward, right?

Hopefully this will have either saved you a click or validated your time in reading the article.

I think the root of the problem can be traced back to the researcher's erroneous claim that "This was not human research".

@denvercoder9 had a good comment that might assuage your concern:

> It's not a ban on people, it's a ban on the institution that has demonstrated they can't be trusted to act in good faith. If people affilated with the UMN want to contribute to the Linux kernel, they can still do that on a personal title. They just can't do it as part of UMN research, but given that UMN has demonstrated they don't have safeguards to prevent bad faith research, that seems reasonable.
