Effectively you could take a watch glass or a petri dish, either not compress to a pellet in the first place, or just break up your sample gently between your fingers into the onto the watch glass or into the Petri dish, then just place that on top of the biggest magnet you can find and pluck away any floating fragments with plastic tweezers… seems simple… assuming you appreciate the sorts of thing’s about solid powder chemistry (which can seem a lot more like applied geology than the kind of chemistry most people are used to)…

if you want to see some interesting things and like a good chemistry video I thoroughly recommend searching for dry powder on powder chemical reactions… most of them are fire related demonstrations but it can be interesting to see them gently spoon a powder on top on another powder and nothing happens, until they poke it with a stirring rod hard enough to press the powder firmly against the other powder and get the reaction surface area to increase and then it’s off to the races… physical contacts between materials can sometimes not be in as much contact as you think… even when it’s literally pilled on top of the other stuff.
Ah thanks for that, updated!
> Study Deep Blue’s 1997 defeat of world chess champion Garry Kasparov, and your excitement about how quickly this technology would take over other cognitive work would wane as you learned just how much brute human force went into fine-tuning the software specifically to beat Kasparov.

That was ~26 yeas ago. In the intervening 26 years humans have been curb-stomped so hard at chess that certain microwaves might be competitive against human grandmasters. Anyone who doesn't think that was an exciting moment for AI research has impossible standards, we're living in a tiny window of existence where humans were at the top of the intellectual food chain and are now dropping to also-ran status along with the rest of the meat-based animal kingdom.

All these moments are the real deal. The idea that somehow this particular step change is even unexpected is missing the forest for the trees. The trends that have been observed since the beginning of computers are chugging away so quickly the whole process may well happen in a single generation.
Okay I went over the slides and good lord this would have made my life easier not too long ago.
The video is actually showing an already quite tiny flake of material – the wooden object he's using to point at it in the beginning is a toothpick. That's why the rest of the video just shows the view through a microscope.

Breaking it into even smaller pieces is going to require some specialized equipment. And it's only been a few hours since the video was posted.

>The real problem is cost of course. Part of that is e-ink is still governed under a patent you must license and pay royalties to if I recall correctly

This is a common myth that's echoed without a source. It's not patent, it's scale - there are literally 6 billion (LCD) smartphone users out in the world (it might be up to 7B by now), with lots of those users owning multiple smartphones. And of course, there are loads of other devices with LCDs: laptops, desktop monitors, TVs, self-checkout kiosks at supermarkets, smartwatches, tablets, LCDs on a fridge for some reason, etc etc etc.

E-ink is orders of magnitude lower in production scale, without a clear way of expanding the market beyond just ereaders/enotes (which are a luxury; you can read ebooks on a smartphone/tablet and most people own one of those already), and possibly supermarket smart-pricetags.

So, does that mean E-ink faces zero competition? No! DES screens are competing against e-ink with their cofferdam tech (where instead of sprinkling on microcapsules, they capsule structure is built directly onto the substrate; it reduces thickness and theoretically increases pixel density, but loses the "grain" effect of E-Ink's MED in favor of a less-aesthetic regular grid shape).

If E-Ink could improve refresh rates then they absolutely would - it's the most visible feature they could possibly add, and is directly applicable to e-readers, which are currently their biggest market. And their biggest buyer is Amazon, who have poured a whole lot of money into the tech (and who sell Kindles at-cost or below) and if it really were patents blocking faster-refreshing screens then Amazon would just buy E-Ink, outright. It's not new - look up LiquaVista; they were bought up by Amazon, Amazon's not afraid to buy up companies. Plus, E-Ink still have to compete against second-hand e-readers they've already sold; there are E-readers from 2012 that will read a .epub just fine, and that's all you really need for an e-reader.

If you're wondering why Amazon killed LiquaVista, BTW, apparently it's because shrinking the pixels horizontally causes a chromatic aberration effect when the vertical color-layers are viewed from an angle, so shrinking the pixels horizontally also requires shrinking them vertically, which makes it extremely difficult to manufacture the pixels without them leaking and causing a terribly low yield rate. Also it didn't help that a bunch of the original company's VC raising was done just before 2008.

Rosalind Franklin's work paved the way for Watson and and Crick. She and her PhD student took the photo that showed the double helix. The scientist leading the team at the lab, Maurice Wilkins, showed the photo to Watson and Crick. He and Franklin did not work together, and she was hired while he was not there, under the impression she would be working alone. And so she did. Wilkins was not involved in the taking of the photo, yet he shared her private research with Watson and Crick.

This photo was the missing piece for them to understand the structure of DNA and Franklin was not credited for it at the time. Wilkins, meanwhile, received the Nobel prize with Watson and Crick despite the single biggest contribution that came from the lab being Franklin's photograph.

It's nearly impossible to overstate just how pivotal and important this photograph was. There was no theory or model at the time that would have gotten them to understanding DNA. This x-ray crystallography photograph was THE missing piece.

Watson, Crick, and Wilkins could have properly credited her at any time. They included her photograph in the paper, explained how important it was. She wasn't even mentioned. They effectively plagiarized her work and took the credit.

I know the nuisance of having to tiptoe around files you don't want to add to history.

In case it helps your use case:

git update-index --assume-unchanged <file>
git update-index --no-assume-unchanged <file>

This would ignore changes while you're testing - but you have to remember to turn it off or, iiuc, you won't pull intentional changes either.

You might find hooks useful too. Not to assume your knowledge, these are shell scripts placed in .git/hooks that are invoked, e.g., before commit or before push. You could have it parse git status, detect changes to <file>, prompt for confirmation if changed and remove from working set if the change is unintentional.
> the free trade system of the US would have surplanted the pre-existing empires and their embargoes

This doesn't make any sense: free trade is not a magic spell against the desires of imperialism, and the US embargoed Japan slightly before Japan attacked the US (but long into Japan's war with China).
Hey, yeah sure, let's see. I started working this morning at 07:45, it's now 13:45. I had a 20 minute video conference call and watched two 15 minute videos on Youtube. At idle, I had ~3 watts, doing small typing things, coding, I had ~5 watts. During the conference call I had ~15 watts and during the Youtube videos powertop reported ~9 watts.

So have been going for 6 hours, definitely some heavier CPU usage during the conference call and youtube videos, current battery is at 33% and indicates (based on my current usage: updating my blog and firefox'ing around) 3 hours and 45 minutes left.

"Cannabinoid hyperemesis syndrome (CHS) is a condition that leads to repeated and severe bouts of vomiting. It is rare and only occurs in daily long-term users of marijuana. "

That is what Cedars-Sinai Research are saying.

And it is not rare as they say it is. Some ten people in my old Baltimore neighborhood came down with it.

And it has affecting someone I know ... daily for 3 years continuous.

Coupled with the how strong the marijuana addiction has been, it is egregious to see how these human beings would check themselves into ER almost weekly; a constructive feedback mechanism is sorely missing within their pre-frontal cortex part of their brain.

While hard to quit, a super long hot shower is often the soothing mechanism to recover from extreme abdominal muscular strains after having worshipped the pearly-white porcelain gods; yet, this relief remains but a platitude.

It was such a sad feeling to watch them cycle this addiction, over and over ... and over.

Rare? ha.

So you give a 5 star review when someone does their job? I always assumed such reviews should be reserved for those who go above and beyond. For your job it should be enough not to get complaints. At most a yearly or quarterly “satisfactory” should suffice. But now we’re offloading the responsibility of promoting everyone on customers. Every single service or product you buy requires a review and/or a tip.

Where on the S-shaped curve are we? I am curious if one day the paradigm that brought forth the current chatbots has to be abandoned because it's reached his limits, and a new approach will replace it.

But certainly it has inspired the field of AI massively and I expect many new developments which will lead is into a future that resembles sci-fi books and movies.

I am also interested in what good sci-fi will look like in the future? It looks like "the singularity" is defined by the limits of our imagination. We cannot imagine what comes after it, so this means we cannot write sci-fi on it, right?

While I love the ingenuity of this system, I have some trouble seeing it used as an economically viable energy storage option. According to the article, they would need about 45 m3 to store 10 kwh. At a concrete price of 200-300 $/m3, that would come to 9-13.5k USD just for the concrete. That's omitting any costs for the carbon black electrolyte, material processing, electrolyte separators and other things, so a very optimistic estimate.

Meanwhile, battery prices have fallen so much that you can buy 10 kwh of Li-Ion batteries for about $1500 ($150/kwh 2021 prices). The saving grace might be to have it do double duty as a structural element in the building, but many other posters have pointed out that there are many safety and construction problems that would have to be solved for that first.

In physics in college we were grilled in verbal discussions with professors and an assistant for ~30 minutes or until the professor had found the limits of our knowledge, one I had went on for 50 mins.

The entire grade of the diploma was composed of all the verbal tests and the grade of our thesis (pre B.Sc.) - so there had to be a point where you knew virtually everything well enough to explain it at least in one way and derive some relations or sketch a derivation if prompted to.

The flaw here was the personality of professors - some were easy to piss off, others more patient.

I think it's common for people to forget that the substance is not always the addictive part by itself. It's just as easy to become addicted to the side effects, like how it makes you feel or not feel. It seems to compound the judgement problem quite badly.

I am too; it's hard, now, to imagine anything dethroning git, but presumably something will do so one day, and this could be that thing.

SQLite uses a custom vcs called Fossil, but doesn't make much effort to push broader adoption (afaics) so it remains academic at this point.

Jujutsu keeping git compatibility looks like a differentiator that reduces cost of adoption. I'm excited!

International travel was not easy nor reliable during the pandemic, with many borders de facto closed or severely restricted, with quarantines, tests, etc.. needed.

So practically impossible to make sure the drilling season could happen with the crew required and then get them home again.
Hey, yeah sure! Erm, let's see. So I use libvirt and QEMU/KVM, where libvirt is essentially an api that makes interfacing with QEMU and KVM more consistent and nicer.

Then I use virsh (command-line) and/or virt-manager (gui) to create virtual machines (these in turn talk to libvirt). The machines kan be anything Qemu supports, so you can emulate PA-RISC, Alpha, Mips, ARM, i386, AMD64, you name it. You can then install OS'es on them. There are some freaks out there that have been running Windows NT MIPS and HP-UX 10.20 for PA-RISC on it.

Most of my machines are doing KVM, which essentially is hardware-assisted virtualization. This requires the VM to be AMD64 though.

I currently run 10 virtual machines:

castel (rhel6)
- chimera (chimera-linux)
- dragon (dragonflybsd6)
- falcon (freebsd13)
- gygax (guix)
- haiku (haiku)
- nomon (netbsd9)
- seven (win7)
- square (winnt)
- xenon (alpine)

You have a gui to these things (and SSH of course) through Spice. With the right drivers and agents (not available for all operating systems) you even have automatic guest display resizing, mouse in/out, copy/paste, etc.

> he, and many other core Windows engineers lined their pockets for years - write complex implementations, do the absolute bare minimum documentation, then take a 6 month sabbatical and publish a reference book that was absolutely required to actually use the API.

If you don't spend enough time on design, it's easy to wind up with an overcomplicated API that lacks documentation.

I wonder if the book was just a "convenient side benefit" of Microsoft's general failure to invest in developer UX. (At least at the time.)

There is another point to consider: more and more people are writing code without being experienced programmer, thanks to easier languages, better IDE, more streamlined lib API, and now, even ChatGPT.

A geographer scripting her GIS in Python or a quant doing some pandas analysis has a very limited programming experience, since her expertise is in her job.

And so we see more and more code produced by people that don't know what is slow and fast, what is safe or dangerous, what is maintainable or not. This code is popular, because it solves a real problem by people deeply familiar with the problem, way more than a programmer would be.

I have an example at $current_client, where they have some matlab code that handles tremendous amounts of money, with no comments, no doc, no tests, side effect everywhere and some interesting quadratic behaviors. They solved by loading balancing the thing on 6 servers with 17 processes, and manual testing.

Unlike the effect on nuclear fusion, the idea of using SC as storage devices is pretty much pure theory.
