To my knowledge the only recent project using ternary was the cryptocurrency/token IOTA, but even they dropped it.

I don't think there would be any gain from ternary unless the hardware was using trits as well. But all of our computing hardware is binary at the moment.
Are we talking about metal instruments that are later resterilized and reused? How much waste does this create, finnancially and in terms of material?
There is as good interoperability as is possible with various transition technologies allowing IPv4 and IPv6 hosts to reach other, with various variants of NATs or tunneling of IPv4 over IPv6 and vice-versa, mapping individual IPv6 addresses to IPv4, mapping the IPv4 space into IPv6, etc. etc.

The basic problem is though that IPv4 has no forward compatibility.
There is no way to build anything that has a larger address space than IPv4 and remain reachable for an IPv4-only host, since the IPv4 header has fixed 32-bit address fields.
This alone is the main limiting factor of the transition (combined with people refusing to dual-stack).
Well, if it’s their language, why are not going to call it “vasco”? They are indeed “vascos”. Seems fine to me.
I'm not sure I understand your point, are you saying that airships don't work? Because the Hindenburg was able to take 100+ people across the Atlantic (86 years ago!), that's much more than the maybe 10-person "luxury RV" that the OP was suggesting. Today's Zeppelin NT semi-rigid airships are reasonably small and can carry 10+ passengers on shorter flights.

Yes, airships are expensive, inconvenient and slow, they leak helium and they require huge hangars and mooring masts, but that's far cry from "can't work".

That is extremely related. We have the extra captured energy because we have base load handling plants that can't scale down quickly enough. This is not a new effect or something people suddenly started caring about.
This guy Les put together a piece of software to view/calibrate a spectrum[0]. He also has a YT channel[1] where he builds a couple RasPi spectrometers using pre-made spectroscopes that run $50-100, but the whole package is a lot more compact.

There are also a number of spectroscope enclosures on thingiverse, but it's always so hard to gauge if any of the projects are actually worth printing. The most dead-simple and cheap example I found used the same slit/CD plastic combo capped onto the ends of a paper towel tube.

At the other end of the scale, if anyone wants to play you can run a little openpower CPU on an FPGA with completely open source. https://github.com/antonblanchard/microwatt

It's capable of running Linux, some example docs are https://shenki.github.io/boot-linux-on-microwatt/
The toolchain consists of "apt install gcc-powerpc64le-linux-gnu" on Debian, no funny downloads. And if you want to target a Lattice ECP5 board even the FPGA tools are also all open, thanks to Yosys and friends.

All the openpower ISA spec PDFs are available for perusing on the openpower site.
this is hyperbole, wasm is just code, it has nothing for data, networking, instrument, observability. How do you deploy your stack to wasm? You compile all the services to it, then what? Write more code to wire them together?

You don't even really need heat though. I spent a couple of months with one of these in 0c to -20c conditions and was never cold https://rab.equipment/uk/expedition-8000-suit

You don't end up doing the laundry etc so often though. I think passive haus stuff has more chance in the market.
Ubuntu: Do I need anti-virus software?
Am I the only one thinking it's a little bit absurd that the official Ubuntu docs recommend against Anti-Virus software because "Linux viruses are so rare that you don’t really need to worry about them"?

I mean, obviously Anti-Virus software doesn't guarantee jack-sh*t but a reasoning of "Linux viruses aren't that common" seems weird. It's like saying that OS X cannot be affected by malware IMHO.
> 250 tonnes is A LOT to lift. Look how big a hot air balloon needs to be to lift a few passengers in a basket.

Does it scale? Can you strap 10 of those things together (perhaps using some sort of scaffolding) to lift 10x the weight?
As far as I know, "industrial society" will still last for another centuries so there's no "problem to this narrative" as you say. It's like saying "the problem with life on Earth is that it depends on the sun which will explode some time in the future"
So I guess what you're saying is that ignoring reality maximizes your own perceived happiness. Would explain a thing or two about our "leaders" and the state of the world.
> So it is huge, but well within historic capabilities - and materials science has come a long way since then. I'm quietly hopeful for this.

The problem is not building the thing (though it is one problem), it's that if you're using this as a crane you're moving an entire baseball field with a decimeter if not centimeter-scale precision.
>That doesn't make a lost of sense. If someone swoops in at the last minute and prevents the chaos it will still be prevented. And I'm not saying that the Texans are going to do that, just that it is one option. The existing operators might learn from this and harden their infrastructure.

No, I said that someone would "swoop in and *profit from stabilizing some preventable chaos*". You even fucking quoted me saying it! The comment is right above us! You even encouraged this outcome ("Some people like making insane revenue. Possibly even some Texans.")! That incredible misapprehension certainly doesn't make any sense to me, unless--

>I don't really understand your position if so

It's pretty clear you're doing ideological battle here. You're unwilling to face the recorded facts of the situation, let alone what your conversational interlocutor is actually saying, so you replace that with your own imagination. Indeed, you make an argument that you imagine me making, and then admit that you don't understand it -- isn't this definitionally a strawman? Why bother with this?

No matter your position on my position, it's pretty clear we're only ever going to talk past one another: your axiomatic assumption that the free market is the correct way to run a natural monopoly like a utility is IMO as wrong as your position on how the free market should have responded. It's only "overengineering the average case" if your instrumental goal is to "make money by providing power" -- if your instrumental goal is to "provide power, in exchange for money", the calculation changes entirely. Suddenly, it's not about winnowing another few percentage points out of a maintenence budget so some MBA can get a new car -- it's about securing the provision of a necessity of life, for a dollar or two added to the end-user's bill.

If you're still interesting in prosecuting our "discussion", I suggest you go answer this guy's question instead [0] -- if you do genuinely think that they were caught off guard, and that they'll improve the (proven to be fabulously profitable!!) situation in future, go explain it to him. It's not about what should happen or what might happen now, it's about what's already happened and what's just transpired.

Can I mention that I found that the most horrible book I have read in years?

The first 50 pages were doable when scrolling through. But soon it dived into how introvert people can be successful, while that success is measured in extravert ways. Like the introvert guy giving presentations about how to be successful. For me everything was "feet on top", "upsidedown". And all very much about looking successful and making an impression. It didn't do any justice to what I would want from my life, more like the opposite. I don't want to be like Bill Gates.

The only thing I took from that book was the description of three personality traits; shyness, introversion and HSP. They seem the same to other people but are very different. Shyness is about fear something might happen in response to what you do. Introversion is that you mostly gain energy in quietness, less in social situations. And HSP means that someone is sensitive and everything comes in quite hard.

An EVs battery pack will generally last as long as the car. A common warranty is 80% capacity after 8 years, and degradation generally flattens out after losing the first 10%, so 16 year minimum lifetime is a reasonable expectation, and 20+ years seems likely. There are 10 year old Leafs with the original battery on the road right now, and that's pretty much a worst case scenario for an EV battery (older battery chemistry, no cooling, and low capacity meaning users cycle often between very high and very low charge)

EV battery packs are routinely reused for grid/industrial energy storage.

EV battery recycling seems to becoming profitable. It's a pretty ideal scenario for recycling (high volume of identical cells).

EV batteries won't be more of a waste problem than car lead acid batteries, one of the most recycled items in the world.

> All of the benefits of an EV and traditional ICE engines with none of the draw backs.

You won't have all the benefits of EV (low complexity, volumetrically efficient drivetrain).

If you're going to have a battery big enough that you can charge at home for daily driving, you're going to get an extremely costly vehicle.

Hydrogen is one battery breakthrough away from being dead for cars forever. If the cost is halved and range is doubled, the niche for hydrogen cars will be so tiny that hydrogen fueling stations will be unsustainable.

Hydrogen hybrid cars is essentially a solution that kills itself. Charging will always be cheapest, so you'll want to maximize charging over hydrogen fueling. It'll incentivize the construction of home charging, street side charging and fast charging at all kinds of shops, restaurants etc. Most people will drive pure BEVs, and those that have hydrogen hybrids might fuel a handful of times a year. Every time batteries improve, the niche for the hydrogen hybrids will decrease. It's a terrible economy to build hydrogen fueling stations in.

A hydrogen fueling station exploded near my home btw. I think eventually hydrogen will be completely safe. But it seems very likely that a few accidents like that will happen before then, which may kill any momentum hydrogen manages to build. Hydrogen explosions are scary, it can be heard for miles away.
School buses need to last for decades. Lots of school buses have 250k+ miles on the odometer. When I was in highschool, I rode on a school bus with over 1 million miles. The thing was ancient and you could feel every gear change.
MacOS seems to be a good place to be if you're making paid desktop software. There's a lot of Windows utilities that are freeware and of course Linux is loaded with FOSS.

I only run macOS on my laptop and yet it's where I've spent the most money on various utilities.

MacOS-only software I've paid for: Bartender, BetterTouchTool, Forklift, SoundSource, Pixelmator Pro, iStat Menus, Nova, Alfred, DaisyDisk, and some other things I'm sure I'm forgetting.
Frequently, I search ddg, fail to find what I'm looking for, and then search Google. Or don't bother searching ddg on a certain kind of search because I know it won't find it. Both Google and DDG are mediocre versions of 2010 Google.
Neither is being introverted/extroverted.

Our mind is more complex than simple dichotomies like this assume. We all behave like "introverts" in some situations and like "extroverts" in some situations. We constantly adapt to our environment and our responses to external stimuli are not stable in time. They also depend on our internal state like hunger, tiredness, etc. much more than these sort of classification schemes would have you believe.
They were also stretched to the brink under the big flu seasons of the past.

But back then we didn't have many tests, which meant hospital personnel would work even when they were a little sick.

Not having those people around, means that capacity has to be increased, which is very hard when almost everybody gets infected with Omicron.
I’m surprised. I would have assumed that the borrow checker is critical to ensuring your code can even be compiled.
> Why. All models are flawed, some are useful. Kids learn mixing paints, that's useful for arts and crafts. Students learn more advanced models depending on their needs.

:) Partly-in-jest paraphrase: Most all models used in science education are needlessly ghastly flawed, leaving students and their teachers steeped in misconceptions. Some are useful - for important exams, or for collaborating with teachers in pretending topics are understood, though vanishingly few provide transferable or operational understanding, let alone integrated or interdisciplinary or rough-quantitative understanding. Students develop less dysfunctional understanding depending on their needs, which can be surprisingly limited. For examples, students empirically don't need to know the color of the Sun to be first-tier astronomy graduate students, nor the order-of-magnitude size of cells to be first-tier medical graduate students, so teaching the wrong color for the Sun, starting in K and continuing into undergrad intro astronomy, and teaching size/scale unsuccessfully from middle-school through undergrad, are in some sense not failing to meet student needs.

Shrug, ok. Also, it's unclear society needs, wants, or would appreciate, or even tolerate, students making sense of the physical world.

But... it can be fun, to at least discuss and explore, how we might go about it, were that an objective to be intensively pursued. No?
It doesn't look big enough. Basically it's Archimedes principle, same as for stuff that floats:

The force produced is the weight of the mass displaced. So a hole in the air would lift up an equivalent mass to what the air in that hole would have weighed. For a ship this is a heck of a lot, since water is a lot denser than air. You can have a huge cruise liner because the hole it makes in the water would weigh 1T/m3, which for the size of such a ship is enough to lift up a massive chunk of metal. But air is nowhere near as dense, so even a cruise ship water-hole sized balloon with magic gas that weighs nothing would only be able to lift ca 1/1000 of the ship.

One trick you can do with air is heat it up so that the atoms push the sides out more, making your balloon bigger for the same mass. I'm not sure how to quantify the difference though. I suppose you take the ideal gas law and say it's proportional to the absolute temp? Limited how hot you want to make the thing that's naturally at about 300K.

Can't tell how big they intend to make this but it just looks like isn't big enough. A big enough balloon would also give rise to other engineering issues, like what do you do with wind and how to you keep the helium inside?

Also if this kind of thing generally worked every moving company would have one. Stick a balloon your sofa, get the kids to take it to your new house.

In the sense that lift is linear by volume yes, but the driving complexity I expect would increase superlinearly.

If you're strapping 10 things together, you're now dealing with a much less rigid structure, the straps/scaffolding are significant points of failure, and the attachment points don't scale the same way so you have to add an even more complex (and tangle-able) web of cabling for your payload.

Forbidding scrapping should be allowed and respected, especially scrapping by businesses.

Scraping by itself shouldn't be illegal per se but not respecting policies and using glorifed bot nets won't help anyone. Scraping costs the hosting person/ company money and/ or resources. For example, the advertised use case of scrapping a job board to create an aggregator for job postings is maybe good from the point of someone searching for a job but a hefty punch to the hosted of the job board that has potentially hefty costs (running the board, moderating, ...) without any gain.

Scrapbee is not helping anyone but themselves and is only challenging the legality of commercial botnetes IMO.

Edit: changed 'public botnet' to 'commercial botnet' in the last sentence

Thanks for the detailed thoughts! Appreciate it.
yep my system also has that option, although my laptop doesn't officially support Windows 11 so maybe there's that. I still don't understand Microsoft's arbitrary decision to not officially support my CPU (even though some Kaby Lake CPUs are supported and newer slower Pentiums are also supported smh)
Being required to agree on something in advance with your prospective spouse would be different from agreeing to go with the default. It means learning a bit about what is standard, and putting some thought into whether what you want is different from that. It would also remove the negative signal of asking for a prenup: if everyone is required to talk and agree on something, then you aren't doing something that indicates low confidence in the success of your marriage.
At this point the C probably stands for Cthulhu because the language borders on becoming a summoning ritual for eldritch horrors.
Not surprising that is the only way it managed to win the performance game against safer systems programming languages.

"Oh, it was quite a while ago. I kind of stopped when C came out. That was a big blow. We were making so much good progress on optimizations and transformations. We were getting rid of just one nice problem after another. When C came out, at one of the SIGPLAN compiler conferences, there was a debate between Steve Johnson from Bell Labs, who was supporting C, and one of our people, Bill Harrison, who was working on a project that I had at that time supporting automatic optimization...The nubbin of the debate was Steve's defense of not having to build optimizers anymore because the programmer would take care of it. That it was really a programmer's issue.... Seibel: Do you think C is a reasonable language if they had restricted its use to operating-system kernels? Allen: Oh, yeah. That would have been fine. And, in fact, you need to have something like that, something where experts can really fine-tune without big bottlenecks because those are key problems to solve. By 1960, we had a long list of amazing languages: Lisp, APL, Fortran, COBOL, Algol 60. These are higher-level than C. We have seriously regressed, since C developed. C has destroyed our ability to advance the state of the art in automatic optimization, automatic parallelization, automatic mapping of a high-level language to the machine. This is one of the reasons compilers are ... basically not taught much anymore in the colleges and universities."

What counts as "truly" off grid to you? Start nude with a rock? Even primitive people were born into a world with pre-existing humans who have some form of technology. It's not electricity, but there is a "grid" of some form.
