That's a rotating spindle, which indeed can catch a loose thread and reel it in. An oscillating cuter moves back and forth, so it unrolls just as much as it rolls, with no net pull.

And if the oscillation strokes are short enough it can saw rigid material while just vibrating jiggly flesh (this is how the saws used for cutting off casts work). Though cardboard is also pretty floppy, so the mechanism here is probably different (mostly the puck guard keeping fingers out)

Source for any of those claims? It's pretty well known after a few weird political fights that she grew up in a tiny house in Yorktown and that her dad died when she was a freshman in college and that her mom was a house cleaner. [her childhood home: https://pbs.twimg.com/media/DhCMERUXUAAY68Z?format=jpg&name=...]. Hard to square with her family "owning multiple brownstones".

Trump's dad gave him millions of dollars to start businesses and then left him somewhere near a billion when he died.

I think those are two pretty different upbringings!

> https://ocasio-cortez.house.gov/about > > After high school, Alexandria attended Boston University, and graduated with degrees in Economics and International Relations (and tens of thousands of dollars in student loans). During this period she also had the opportunity to intern in the office of the late Senator Ted Kennedy.

She was indeed a congressional intern, but then her father died and family finances got rough, and a year later Ted Kennedy died (August 25, 2009) so she lost the job in his office.

> Following the financial crisis of 2008, tragedy struck when her father passed away suddenly from cancer. The medical bills and other growing expenses placed their home at risk of foreclosure. Alexandria pulled extra shifts to work as a waitress and bartender to support her family,

Her father seems to have been in the business of home remodeling and renovations. I haven't found any source for "owned multiple brownstones", but a little bit of house-flipping or some rental properties wouldn't be weird to see in that kind of business. Being a landlord with a mortgage doesn't necessarily mean huge wealth, and it it's easy to believe a combination of cancer treatment bills/being unable to work/2008 housing crisis could take a situation like that from comfortable to house-poor to foreclosure on upside-down loans in an awful hurry.

Ok but how did the plant know that is wasn't being successfully spread by mammals..
puetzk · a year ago
Evolution doesn't plan ahead. Various plants got various random mutations that produce various random chemicals. The ones that were tasty to birds but disgusting to mammals for their seeds spread all over and ended up pretty widespread, so they survived and became common.

The ones that were repulsive to birds but tasty to mammals got eaten by something that grinds up their seed, and so they are extinct. Or, (after humans invented agriculture), possibly got domesticated and became extremely numerous since we'd intentionally save some seeds to plant despite eating the rest.

But there was no awareness and no plan, just chance and history and whatever happened to work.

Phones used to have fm receivers! It was common in the early 2010s. They used the headphone cord as an antenna.

Unihertz phones still do (even the tiny Jelly Star)

we aim to build a monitor, but hardware companies arent very hot for VCs, so cash flow from selling the tablet is the primary way we are going to fund building a monitor, phone, and laptop

Ah, so the next stage would have been to add a "bug" in xz that would trigger during the supposedly sandboxed execution, when presented with certain input files. Clever.

Well, is also quite possible that adding such a bug was the previous stage. Or even just having found one that you didn't report/fix...

When doing reproducible builds with Nix, how are people dealing with build artifacts that can't be downloaded? I see that I can do a fetchurl with a specific URL and hash, but this obviously fails if the content is missing.

On Debian pinning is a little strange. You can try `apt install foo=1.2.3` and it will work until the next versions is released. Debian removes old versions from the mirrors. However they operate a snapshot archive with all the old package versions, so reproducible builds can use that and should continue to work over many years.

Does Nix have a way to ensure pinning continues to work over many years?

puetzk · 2 years ago
> this obviously fails if the content is missing.

It doesn't, actually - all the fetchers are [fixed-output derivations](https://nixos.org/manual/nix/stable/language/advanced-attrib...) where you specify not only the source, but the hash it is expected to produce. And so the fetched files will be hashed and placed in the nix store under that hash. And therefore subsequent builds using that artifact will use the already-stored artifact and not care if the source is reachable or not. You know that all "external" inputs will be captured by fixed-output derivations, because any derivation that isn't fixed-output is blocked from network access.

For anything built by the hydra CI, this will be retained on central cache.nixos.org. Or you can copy from a store of some machine that has it.

Now, if it's something not on the official cache.nixos.org, and the source is gone, and you've lost (or pruned) your store, you will need to get the file from somewhere and put it back in your store: https://nixos.org/manual/nix/stable/command-ref/nix-store/ad.... Or you just change the source URL (this won't change the derivations depending on it, because the input being transferred is identified by the hash that is to be delivered, not by the URL it comes from).

Meekro · 2 years ago
I've read the website and all the comments and I'm still totally lost. Guess that means I'm not the target audience? To me a "music drop" is when someone releases a highly anticipated new song.
puetzk · 2 years ago
The (beat) "drop" is genre term for a buildup of tension, sharp pause, and then suddenly resuming at greater intensity/tempo. Usually associated with EDM/dubstep.

E.g. https://www.youtube.com/watch?v=db5f-A-vSyw (drop at 0:45 seconds in the video, thought the countdown to New years that takes up most of the stage should make that obvious anyway)....

Thought it's certainly not a new thing - plenty of classical music has similar moments, e.g. the 3rd movement to Beethoven's 5th symphony: https://youtu.be/xAQFJ1YpFaI?t=279 ("drop" at 5:05 when the horns blast their way in...)
