>Floats are probably the best approximation of irrational numbers near zero.

Floats are generally better near zero, but better (although less useful) approximations exist.

>Rational numbers don’t need to be approximated

Nonsense. "rational" datatypes are far less useful than floats. Approximating rationals by floats is usually better.

FYI rational datatypes can not support operations which result in irrational numbers, such as exp, sqrt.

>where the hardware itself limits precision

Hardware does not limit precision. It implements IEEE 754.

Those are arbirtrary precision numbers.

>There are corners we don’t need to cut anymore, because a half century of Moore’s Law has already paid for better tools if only we would claim them.

Total nonsense. Fast floats have never been more important than they are now.
$lhs ~~ $rhs

is mostly sugar for

$rhs.ACCEPTS($lhs)

and then method resolution (including multimethod handling, of course) figures out which ACCEPTS method to call and that does ... whatever the author of the type implemented.

('mostly' because ~~ actually aliases $lhs as $_ and passes $_ as the argument to ACCEPTS)
Is this measurement on the entire language or specific features? Because if its on the entire thing, I can see the results not being good (all over the different quadrants).

I do agree though, that if a language surprises me, it should be to the left quadrant in this case. If a language is not surprising me, it should be delight as well.

I think this was overall positive as a social phenomenon. It did not result in a superconductor future, but it got a lot of people interested in science and practical experiments. The biggest cost was several labs doing work they wouldn't have done otherwise. And that seems fairly minor when compared to the cultural exposure that their work received.

It's unfortunate that it probably won't work out. But this was fun. Good story, good experience.

3nm has already hit mass production. Considering this fab won't be ready for at least another two years, 2nm will have hit mass production already.

22nm dates back to 2012, and TSMC has been doing 14nm FinFET mass production since 2014. So yeah, a decade behind cutting-edge can indeed be called "old" when the entire point of the Chips Act was to catch up with Asia and become a center for innovation.

Hah! Or rather Wow!!

I was aware of this piano because of the Hyperion Knight recording and have always had an interest in 'one off' instruments, especially pianos. But I never caught on to this amazing story of how it came to be, the mixture of constraints, determination, inspiration and generosity working all out to result in this incredible creation.

To 'build a piano' is no simple undertaking, even if you already have a lot of shop knowledge tools and instrument knowledge. I've rebuilt one that was neglected and that already required a ton of knowledge and I've made some (technically minor) modifications to existing instruments[1]. That doesn't begin to put me in a position where I would attempt to build a piano from first principles. All the parts have to collaborate just so to get a working instrument and the history of the piano is littered with failures. To see a one off made by a young man like this is impressive already. But to see one at this level of quality, that's something else entirely, I have no words to really express how impressed that leaves me.

> the cost / benefit tradeoff is in favor of the 10 year old processes.

I thought a big part of the reason why that's the case in general is because the old fabs that house those old processes have already been depreciated - customers basically only pay for maintenance and the of raw materials.

But that doesn't really apply to brand new fabs.

No, it's not like engine breaking (see https://en.wikipedia.org/wiki/Engine_braking for a description of why that works).

https://en.wikipedia.org/wiki/Thrust_reversal describes thrust reversal nicely:

> On aircraft using jet engines, thrust reversal is accomplished by causing the jet blast to flow forward. The engine does not run or rotate in reverse; instead, thrust reversing devices are used to block the blast and redirect it forward.

Take a look at the video of "A target-type thrust reverser being deployed" for an example.

You don't re-fit a fab, you build it from scratch. There is very little technological overlap where it matters due to the shift to EUV. You'd essentially have to scrap >75% of the fab to fit in the new equipment.

It's the relative energy scales in the system that matter. You can e.g. compare the superconducting energy gap to a temperature, for Niobium the gap is around 2.3 meV which corresponds to about 27 K. For high Tc superconductors the story is a bit more complicated but their pseudo gap is 5-8 times higher, hence around 150-200 K. Niobium has a Tc of 10 K, high Tc superconductors (unpressurized) at most 150 K. What's safe to say is that if the temperature becomes significantly higher than the energy gap the superconducting state will be lost as there's thermal tunneling out of the state and it becomes thermodynamically "unfavorable" (this simplifies things). Now there's no reason that we couldn't find a system with a larger energy gap but that gap itself is defined by other properties in the system that have constraints on their own. Fundamentally there's no reason that there couldn't be a system that fulfills all these constraints at room temperature, but there isn't a reason why there should be such a system either. Then again there might be different superconductivity mechanisms that we don't know about yet and that we could exploit, but I think it's not very likely that we'll find a regular material system with these properties because there are not that many crystal lattices to choose from and we've been looking for more than 50 years.

My friend is a private jet pilot, but also partially trained for commercial jets. He says that the article content is a nonsense. Here's his words, translated:

The plane is always using brakes. Reverse thrust reduces landing distance by about 15%, and its main task is to reduce the load on the brakes and prevent overheating of the pads (which lose their effectiveness at high temperatures) and wheels (which would otherwise blow the fuse and release air from them, to prevent explosive destruction). All landing distances that are indicated in the manual and that are calculated by the [onboard] computer are calculated for serviceable brakes and WITHOUT taking into account the use of reverse thrust.

With “brakes disabled” - how can you be sure that you will stop within a runway of a given length? There is no such data, no one has tested it. There are procedures for brake failure, but this is an emergency, there are no landing distances for these procedures, and in any case, pads are still used for emergency braking (it’s just that compressed air/nitrogen is supplied to their actuators instead of hydraulic fluid).
How astonishing. What a wonderful idea and technical achievement!

Oof. Queued RPC is such a siren song; so many developers either stumble into this pattern or seek it out. And it's such a pain. Suddenly the latency of (often user-sensitive) operations is contingent on the latency of a queue consumer plus the time it takes to process everything in the queue before the RPC was issued. Goodbye, predictable turnaround times.

There are some videos at the bottom where it is played. It sounds beautiful. The range is like a normal 88 key piano, no extra keys but what matters is the difference in timbre in the low notes. Your 'regular' piano has what is called an overwound string, a steel string that is covered with one or two layers of copper. This results in a string that sounds less pure. The Alexander piano is special in that it uses no overwound strings, all the bass notes are simply simplex strings at their natural length without added weight to reduce their period of oscillation. It also has a huge soundboard, so presumably it is quite loud, but the main difference is in how the bases sound.

Try getting on a news feed for a day and check the river of news, often very important, that are NOT reported in the USA because they're not important.
I have a serious problem with the obsession we have in Europe for example with American politics.
We live under this assumption that what happens in the USA shapes what happens everywhere else but that is only true to a much more limited extent than what coverage and media attention might suggest.
In fact for Europe I believe that what happens in China for example is right now way more important and impactful.
Not to mention Africa (check what's happening rn in Niger, for example).

Look the problem is simple. Every country is self-centered to an extent about its own topics, issues, and problems. USA is the only country that's absolutely and utterly convinced that when it comes to its own issues, than everyone else is not talking about anything else but that.

If the developers are around, I would like to ask a simple question : Does this app only use realtime data for calculating ETA and routes, or does it learn some statistical regularities in the traffic patterns to make predictions ?

I'm asking because this is the main weakness of all similar apps that I know of, they always give you an estimation using only the current state of traffic on the whole journey, so if you are going towards a busy city at peak traffic time it may add one or two hours to the ETA even if you are still 5 hours away and everything will be gone by the time you get there. Obviously the reverse situation is even more annoying, I live in the Paris area, and when I leave home around 4pm and ask google maps an itinerary, it may tell me I'm only 30 minutes away, but 15 minutes later shit hits the fan and I end up an hour late on my schedule.

Obviously after a while you start learning the traffic patterns and plan accordingly, which is okay I guess, but we're in 2023, how can google not be up to the task of correctly predicting a traffic spike when it's regular on a daily or weekly basis ? Is that just too much data / compute for them ? If anybody has a clue, I'm curious.

> at most, living society should be able to inspect & affect the post-living system (afterlife), but the post living system should be airgapped from being able to (at least, directly) affect the living one at all.

I feel like this hypothetical scenario is contradictory (and, supposing there was engineering behind both this life and an afterlife, is an argument for keeping the two isolated). Data is code, so data collected from the afterlife is potential for "remote execution from the afterlife" (not that humans are computers, but for example traditionalists who were able to directly study the long-dead would act differently than if they had to piece tradition together from scraps of documents - particularly, it would freeze traditions/memes rather than letting them evolve) and therefore death losing its role as the cessation of influence.

Considering the sheer magnitude of the cost of building out a bleeding edge fab, wouldn't it make sense to start with a somewhat older (but still incredibly useful) process node, develop domain expertise and then iterate? Going from 0 to 2nm is sure to yield little more than a boondoggle. Catching up is going to be a decade long process - if not longer. But you do have to start somewhere.
