The continents rarely get pushed under each other, but the ocean floor does commonly get pushed under the continents and back down into the Earth. The Himalayas are the exception where two continents have hit and are still moving toward each other with a lot of crust getting smashed and pushed up much higher than usual. But even in this case the continental crust is not going back into the earth. It is much less dense than the rock below it and thus will "float" on top.

Reconstruction of where the plates were in the past is mostly determined by paleomagnetism (subject area of my PhD). When lava erupts and cools, it gets magnetized in the direction of the earth's magnetic field. This can be measured directly in the rocks themselves or seen as magnetic anomalies in the oceans. Since the magnetic field flips directions every 1/2 million years or so (a somewhat random process) the rocks around the ocean ridges that are spreading and erupting continuously all get magnetized in one direction and then another. This produces magnetic anomaly stripes that have been measured all over the world.

Using these ocean stripes, which can be treated like slices in time, it is quite straight forward to reconstruct what Pangea, the most recent supercontinent, looked like and where it was located when it began to break up about 175 million years ago. Almost all of the current ocean floor was created after this breakup, so before that reconstructions become much more difficult.

This a very simplified explanation. The older the rock, the less likely the original magnetization was preserved. Also, the continents have been growing slowly over the 4.5 billion history of the earth. The earth was almost all ocean at the start. The oldest rocks known are about 3.2 billion years old, so before that almost nothing is known about the magnetic field of earth (some older zircons survive in these rocks, but they are unlikely to preserve a record of the magnetic field). The wikipedia entry on plate tectonics is a decent place to start to read more about the process.
This seems like it's probably enough to re-implement APFS on non-Mac platforms; in fact, the about page (page 6) says as much.

Kudos to Apple for providing the information. It's a hell of a lot better than reverse engineering the thing (see how many years it took to get NTFS down...)

This is certainly true when solving hard problems.

A counterpoint would be that most software used to run businesses is complicated, but not hard (or the hard parts are very localized.) And for these problems it's best to factor your codebase such that it is not required to hold the whole thing in your head.

Because if you do, at some point in the project's history, someone is going to blunder in and make a change that fractures your crystal palace without you even realizing it.
$12 games are an absolute no-go on the App Store. If the app is paid its almost certainly $0.99, maybe $2.

So that doesn’t work, unless the ‘trial period’ is $0.20. And at that point Apple/etc is losing money on CC fees.
If I remember correctly, there was a bug a couple of years back which caused an incorrect time offset between GPS and UTC time to be uploaded to some of the satellites - off by a handful of microseconds. Didn't affect navigation but it did trip a bunch of alerts on systems that relied on precise time. I don't think Google was the one that alerted the USAF to that though, in fact they may not have had sufficiently accurate timekeeping back then.
One reason is may be because it is not 'SQL' DB, which is probably prerequisite for NewSQL category.
Freezing your credit sounds scary, but I do generally recommend looking into it. I froze my credit awhile back now, long before the Equifax breach, just as a proactive measure. Better to do it _before_ your identity gets stolen.

Since the freeze I've opened up a few lines of credit (loans, credit cards, etc). It's not that painful. Most of the time you just find out which credit bureau(s) they're going to pull from beforehand, do a temp unfreeze, and then submit your application like normal. It takes a few extra minutes of your time, but is otherwise not a bother.

There have been a few instances where the companies I was working with were just ... incompetent and didn't know who they were going to pull their reports from. Yeah ... but in those cases I just submitted the application and waited for the rejection letters to roll in, which state which company reported a 0 credit score :P

Is it as easy as before? No. But how often do you open lines of credit or bank accounts? Not often. And I don't think doing those things should be easy anyway. The huge plus here is that you don't have to worry about identity theft like everyone else. I've seen too many friends and family go through identity theft now. It's horrific, stressful, time consuming, and seemingly endless.

And on the bright side, I think having your credit frozen is becoming more and more common, which means companies are getting more used to dealing with people who have them. So the process is becoming more streamlined over time.

Now the caveats. Yes, it cost me money. It may still cost money even with this new law; as a fellow comment points out you may still have to pay whenever you need to temporarily unfreeze your credit. And yes, it's a racket. In many ways it feels like a shakedown. But such is life. People cheat you out of your money every day. This wasn't a mountain I was willing to die on.
I haven't been to meow wolf in particular, but that's a problem with museums in general, especially the ones that attract a lot of children -- science and natural history ones -- you often can't stand in one place long enough to read the captions or use the interactive exhibits. But I don't know what can really be done about that.
Short and simple: yes.

Though the question is how relevant this is. Likely SSH will have moved to something more secure years before any quantum computer with sufficient computing power will become available.

Because that's the thing these scare-stories don't tell you: While the progress in quantum computing is moving very slowly, in recent years the progress in post quantum cryptography has been very fast.

No such thing is happening. We're still in the state of "we're waiting for someone to actually show that quantum computers can do anything at all faster than a classical computer". Yeah, it's probably gonna happen in the not so far future, yeah, there's progress. But saying anything is moving "to practice" is absurd at this point.

“I believe that the clue to his mind is to be found in his unusual powers of continuous concentrated
introspection. A case can be made out, as it also can with Descartes, for regarding him as an accomplished
experimentalist. Nothing can be more charming than the tales of his mechanical contrivances when he was a
boy. There are his telescopes and his optical experiments, These were essential accomplishments, part of his
unequalled all-round technique, but not, I am sure, his peculiar gift, especially amongst his contemporaries.
His peculiar gift was the power of holding continuously in his mind a purely mental problem until he had
seen straight through it. I fancy his pre-eminence is due to his muscles of intuition being the strongest and
most enduring with which a man has ever been gifted. Anyone who has ever attempted pure scientific or
philosophical thought knows how one can hold a problem momentarily in one's mind and apply all one's
powers of concentration to piercing through it, and how it will dissolve and escape and you find that what
you are surveying is a blank. I believe that Newton could hold a problem in his mind for hours and days and
weeks until it surrendered to him its secret. Then being a supreme mathematical technician he could dress it
up, how you will, for purposes of exposition, but it was his intuition which was pre-eminently extraordinary
- 'so happy in his conjectures', said De Morgan, 'as to seem to know more than he could possibly have any
means of proving'. The proofs, for what they are worth, were, as I have said, dressed up afterwards - they
were not the instrument of discovery.”

Yeah I was disappointed with the movement of the horse too :(

I've not read the paper yet, but I wonder if the limited movement of the horse is due to the actuators themselves not being able to deform the horse's legs enough?

Here's an interesting article[1] about how relativity affects GPS satellites. The clock ticks in a GPS satellite need to be accurate to within 20-30 nanoseconds for accuracy, and they tick 38 microseconds/day faster to account for relativity.

Galileo didn't really have to "fool" the Inquisition.

By producing a softer version of the letter and claiming it was the original, Galileo was bowing to the authority of the Church. He knew it, they knew it, and everyone important watching knew it. That was the important thing for the Church, and by accepting the softer version as the original, whether or not they believed it, the Church sent the message to everyone watching in return: don't challenge our authority, and we'll leave you alone.
I voted "no", because I did the math, and I don't think that this project will not be mismanaged, like other projects of this kind of magnitude.

I found the learning curve really steep (even coming from a skateboard/snowboard background, and being a reasonably good swimmer). A lot of it is learning how to read the waves, which is frustrating at first. I've been at it for about a year now and am only just starting to feel things click. But even when I wasn't catching any waves, I loved the feeling of being in the water, feeling the power of the waves, and just enjoying the views of sunsets and the coast.

Definitely get an instructor for your first few attempts. They'll be able to push you and help you catch whitewater waves which will give you an idea if you actually enjoy this thing. Then if you want to be able to actually surf, I highly recommend spending at least 1, preferably 2 weeks at a surf camp with good instructors. A lot of surf camps just hire 18 year old Australian kids or whatever who just want to travel and surf, and while they're great surfers they aren't great instructors. I went to School of the World in Costa Rica and the instructors there are permanent, this is their career, they care about it and they're good at it. They had me catching my first green waves very consistently with help, and progressing from a 9' board to a 6'7 board. After a week and a half there, I was able to go back home and actually catch green waves (inconsistently) on my own for the first time, and build my skills to consistently catching those waves. Getting feedback and being in the water every day helps you improve exponentially.

It looks like 12TB ram is available in eight socket Intel servers? Those are sort of commodity, but availability is limited, and NUMA becomes a much larger issue than in the more easily available dual socket configurations. Looks like Epyc can do 4TB in a dual socket configuration.

Sir Michael Atiyah Claims Simple Proof for the Riemann Hypothesis
My one attempt on a beach in San Diego was not a success, but I'm pretty big/heavy (6'3" 220lb) and I think the board was too small. Also the experienced surfers were unwelcoming and impatient. I was a n00b wasting perfectly good waves.
Perhaps that means this paper invented click-bait.
They break all widely used public key encryption systems (RSA, DH, ECC-based). There are post-quantum systems, but none of them are in widespread use yet.

Symmetric encryption systems are weakened, but can easily be made quantum safe by increasing the key size.

Agreed. It's just reminding me that I need to complete my move away from gmail for other reasons, mostly trust related.
I think it is just due to the fact that Google has such a massive market share. In comparison, Bing seems pretty insignificant and would make less of an impact.
Hey all. We've been building a new solution for blockchain miners, see https://www.packethopper.com/. We make it possible to use commodity networking ASICs to execute a new class of proof of work called Baran. The ASICs we are building on are already used to power the high performance routers used in enterprise datacenters and networks, and so you can now rely on world class manufacturers like Broadcom without worrying that they are selling you obsolete devices having pre-mined all the value out of them! Modern programmable packet forwarding ASICs offer an unprecedented level of computational flexibility, and we're taking full advantage of it. Happy to answer any questions!
A Makefile to encapsulate all the details of how to generate the PDFs.

Text editor customizations to trigger `make <current-doc>.pdf` on save. (Emacs in my case)

A PDF viewer that reloads the PDF when it changes on disk (Skim in my case, which does auto-reload, but I also have some Applescript in the Makefile to poke Skim so that it notices the file change faster).

A good text editor LaTeX editing mode (Emacs in my case).

Random test editor customizations for working on LaTeX.

My main tips are

1. don't be shy of perfecting your work environment

2. use git to track both your work environment customizations and your LaTeX work.
You can begin by always assuming no matter what. There's always more to the story. It's never black and white. Or grey for that matter.

Unless I'm physically there at the time these things happen all we can do is build a good enough idea of how things played out by looking at all the information available.

People in general tend to hyper focus on things sometimes not even relevant at all to the things they want to know and miss the point entirely.

These sites and propaganda exploit our laziness towards due diligence. And it also doesn't help that the world isnt particularly honest with themselves or tech illiterate.

Bruno was killed for freely inquiring into the nature of our universe. In a time such as it was that included religious and philosophical speculation as religious and philosophical ideas formed much of the foundation of how people understood the world. I think it is fair to view him as a hero of science however since he lived in an unscientific time it does not make sense to call him a scientist.

>And where this article is concerned, the Galileo affair stretched something like 20 years and his house arrest in the papal apartments, overlooking the Vatican gardens, was largely the result of decades of political intrigue and him having accrued enemies.

That Galileo's enemies were able to use his scientific views against him is not evidence that he was not persecuted for his scientific views. It is merely evidence that it is possible a more nimble or charismatic political player may have avoided such persecution.

You are correct that there is no truly capital-U-Universal time, but it doesn't matter. You control the whole system, so just choose one and call it "true time" and make everything participating in the system match it. Simultaneity in all inertial frames can be translated between one another, so if you go to a new place that has, for example, more time dilation due to different gravity, just note the parameters and translate it into your chosen "true time" and adjust the spread.

The gyst of Grantham’s essay which I posted below (also at the bottom of this comment), throws into question that optimism. With evidence, Grantham demonstrates the possibility that a nexus of climate change, soil degradation and population growth threatens Africa’s development trajectory. My view is that this will happen within 20 years as banks pull credit lines from farmers at risk of weather shock. Indeed this is already happening and farmer’s production goes off a cliff when they can’t get loans for good seed and fertiliser.

I don’t write this because I’m a doom and gloom merchant. It’s because we need to get real about investing sufficiently to course correct.

Edit: here’s Grantham’s essay:
