OK, crazy idea time.

Couldn't we detect such things with radar? Given the right frequencies, rocks and dirt will reflect - that's how terrain-following radar works.

So yes, I think we could, but there are some significant problems.

1. 1/r^2 power loss, in both directions. We would need a massive radiator, and very sensitive detectors.

2. The detectors are in the wrong place. You send out your signal, and several hours later the response comes back, by which time the earth has rotated. So where your detector has to be depends on the distance to the object, but you don't know the distance to the object!

So we'd need a bunch of detectors at various points around the globe. And we'd need a huge power source.

Which brings me to solar flares. They emit radio waves. Do they emit enough power at the right frequencies to be useful for this?
Fukushima was also caused by an earthquake and tsunami - not exactly a scathing indictment of nuclear power itself.

> We can’t simultaneously all be working at feature factories and making inflexible software

Actually, yes we can. The key insight behind liberal economics is that central planners are incapable of understanding the demands at the edges. The same goes for software - the feature factories can only generate features imagined by centralized focus groups (or even worse, the business desires of the company itself), whereas desires of actual users are much more vibrant than that.
Specifically, they had Teamviewer codes everyone knew or had access to and never rolled them over time. The control panels were just left open on the consoles of the computers. Someone saw the mouse moving on the screen which, along with the settings changes, alerted them to remote access. Scary stuff.
The Helios64 "Full Bundle" looks nice, but only 4 GB RAM seems limited for ZFS. Plus, for 300 USD, there should be a way to set up a similar x86 system, possibly from second-hand parts. I'm thinking some older AMD Zen with 8-16 GB RAM and a Fractal Design Node or similar case.

Yes, I know that would likely use more electricity, but in my particular case (France), electricity isn't that big of a cost, plus I wouldn't be running this 24/7. More like one or two evenings a week. The only reason why I'm not running recycled "enterprise" servers at home is that my apartment is small and I absolutely cannot stand the noise they make.

Ahh, by "accessing its[the page's] contents", I thought you meant keeping track of the priorities of the tasks actually making the read and write operations that cause the MMU to set the dirty and accessed bits.

It sounds like by "accesed" you weren't referring to the page access bit set by the MMU, but rather just having the page mapped in the address space.
That’s the number this study went for, but it also is a number that doesn’t tell us anything about whether the increased chance of hospitalization and increased death rate are due to COVID, due to the first hospitalization, or due to those being hospitalized in the first place already being weaker than the general population.

I wouldn’t call it the most useful one.

If those who were admitted to a hospital with COVID already were less healthy than those who weren’t before they got COVID (and that’s a given. Higher lung capacity can keep you out of the hospital, for example), I don’t think it is a surprise they still aren’t as healthy when they leave the hospital.

What evidence there is a team problem. Like building cars requires all those things and companies manage to do it all the time. Adding the self driving tech in there, ok, but these cars already have teams upon teams of tech already working on them. Each part of the inboard computer has a different tech team which works with a different company it's outsourced to. In fact, sometimes different teams work with the same outsourcing company for different parts. That seems a very much a solved problem.

It also seems like you're not really also applying in the fact self driving cars are approved in how many places? And it takes approximately 5 years to get a standard car to market, getting a self driving car that has been tested in just 10 states, it's unreasonable to expect the value to end users you're expecting to see here. Getting the car to market seems to be the actual problem and that seems more of a legal issue of no one wanting to say yes on the major scale. This is a very slow moving industry, electric cars are basically a solved problem, yet we'll be seeing people buying combustion engine cars for decades.

How long has this project been going on for? 12-years? Seeing management change over that amount of time seems normal. It would be notable if we were seeing 1 or 2 people a month leave for 6 months.

NY Times Review of Gates’ Climate Book Considered Harmful
Crystal has a GC, and also compiles to LLVM IR, so it's a little heavier than what you might want for MCUs. Circuitpython, C-*, Zig, Nim and other co would all be more appropriate choices, generally speaking.

I'd love to see some effort taken to bring Crystal lower and closer to metal but I don't think there's that much desire in the community for it, and there's not enough corp resources to just throw man-hours at whatever the community wants right now. Manas seems to have a little trouble keeping people around the Crystal core team, though I'm not exactly sure why.

It'd be great to have a Crystal that could spit out C or Zig code instead of LLVM IR. That'd be awesome.
If the wide view of the landscape in the US (little) and EU (much) is any indicator I imagine the point at which there is too much regulation is closer to or beyond the EU levels. In the US the never ending stream of new MLM, ICO/DeFi, and otherwise repackaged 'investment' scams is a constant reminder that it's very much a wild west.

Average people in the US need to know an obscene amount just to walk the minefield, while inflation erodes what little earnings they have.

Of course the richest investors can pump money into new ventures started in the lowest regulated markets to realize the highest gains with whatever hoop-jumping to get profits laundered through lowest taxed markets.

I would think a broken-up asteroid would be better, in that the worst possible outcome would be exactly the same as not hitting it, with all the pieces undisturbed enough to still hit the earth.

However there would be more surface area to burn up in the atmosphere, and if you do it far enough out and I'd think it would require very little nudging to move pieces out of the way
UK gravely concerned about Russian military activity threatening Ukraine
All of what your saying doesn't actually contradict what I wrote. The metadata for generics is not used by the VM during execution. It only exists so that you can compile against .class files as if they were source.

IMHO it was still a major design mistake that has cost everyone else more time in the end. A classic near-term/long-term miscalculation. For a counterpoint, C# introduced generics and rewrote the class library. They're in the bytecode, not just metadata. The VM dynamically specializes JIT code as necessary, and shares equivalent specializations to avoid code explosion.

> Also, truly reified generics is really hard.

I think this statement is false. It's not intrinsically hard; it's only hard because of a lot of other constraints. For example, Virgil has "reified"[1] generics since 2.0 and I just use monomorphization. MLton did the same, 20 years back. Code explosion isn't that bad for medium-sized programs.

[1] "reified" implies there is a runtime representation, which is not really what's going on. With static specialization, it's possible to completely compile away any additional metadata representation, as it either becomes implicitly part of a function specialization or the class metadata for specialized classes.

The only real reason I see to not use monomorphization is if you have polymorphic recursion, or first-class polymorphism. Virgil doesn't allow either of those.
The problem is a venture problem / industry not teams and individuals ... VCs have been heavily investing in anything remotely promising because let's face it since smartphone tech hasn't found its solid step into the next level .. VCs have the money they throw it at promising companies, lots of people get rich in the process but the end result is delayed ether no working product or no working business (unit economics) an example is all these ride hailing apps, scooter apps and food delivery where billions has been spent and losses are recorded annually and everyone is happy to move the ball down the field and make it a tomorrow's problem.

I'd rather be pushed uniform information about what a company is up to, than have specific information about me pulled into a surveillance database. Neither one is good, but at least the generic push leaves me alone the rest of the time.
Kotlin feels to me to be in an odd spot. Java really has the incredible last mover advantage and it keeps making the right decisions in my eyes. All thanks to Brian Gotez and the team, they have incredible write ups about the language every month it feels like.

Java is very lucky to have Scala and Kotlin to learn form. I don't really see them ever taking a majority share of Java away, one of my issues when having a dive into Kotlin is the fact you need to context switch between Java and Kotlin libs all the time and at that point I'd rather just stay on Java since its progressing so much at the moment. Have a peek into Project Valhalla.

I wonder how Kotlin is going to be split when Project Loom comes along with their coroutines implementation and colored function issue sounds like another fractured library split waiting to happen in an already niche backend language.

Though its not as if Java is amazing itself, it is a bleed on the eyes, private and public keywords everywhere, no map collection literals is brutal, the cruft of libs, is Spring really the best dev experience you got Java? Lack of upgrading culture sucks, the getter/setter bullshit, and writing it is not 100% joyful like a scripting language would be. Java is very much so an enterprise 'late game' language but is slowly improving its ergonomics through project Amber.

I know people continually say the Java has amazing libs but I'm not having the same experience while trying to make my rails like setup. Where is the Sidekiq equivalent for background job processing? It's not Quartz (thats a dead lib), where is easier storage integrations like ActiveStorage? Where is something like Devise? Java for typical startup web development feels like hard mode and I assume its because Java is largely a 9 to 5 programmers language.

Having said that Kotlin will be the Android goto for the future no doubts there.
So, Capone could have declared his income, but not its source, paid the tax and it would have been impossible to prove he ordered murders (cos everyone was scared) and / or unconstitutional to use his own declaration to convict him of a criminal act.

> Ok, but the UK has a large, integrated, health care system, with an office of national statistics that is following the disease and published this data.

Having an office of national statistics does not mean that this particular paper is being reported correctly by the mass media, it doesn't mean that the paper itself supports the discussion of "long covid" amongst otherwise healthy people, and it certainly doesn't mean that other people on this thread reporting personal stories are representative of the actual risk. That last bit is what I'm emphasizing here. Literally any scary anecdote is amplified, and the (many more) pedestrian anecdotes go undiscussed.

As other comments on this page have noted, there are a number of legitimate criticisms of this paper that should be considered carefully, and even if you don't agree with those, the paper is self-admittedly discussing a predominantly elderly, sick population who were hospitalized for the virus. It doesn't generalize to discussion of anecdotes of "long covid" from much healthier people.

> It also talks about how poorer people, and those from non-white backgrounds are disproportionately likely to have worse outcomes. Just because you don't see it happening in your circles, doesn't mean it's not happening in other ones.

You're making assumptions.
"Legitimate" because it is open protocol (TMTP), decentralized, store-and-forward, n-identity, and open source.

Email is a network, not a product or service. TMTP is the basis for a new network.
Certainly, absent the VC model (or some other wealthy investor model), it would be much harder to scale businesses that are capital-intensive and/or aren't profitable in the short-term. So presumably absent VCs, you'd have a lot fewer crappy tech startups but you might also not have the success stories--or at least it would have taken them a lot longer to get there.
It depends on the nature of the commute. I've had a commute that was an hour each way, and that worked extremely well for me because the first half was by train, which is fairly low-stress and can be part of a relaxing morning routine (breakfast / coffee / reading the news), and the second half was by bicycle over quiet bike paths, which was important daily exercise that I would have to do anyway one way or another and also woke me up. The only part of the arrangement I disliked was the expense of the train fare.

Commute time doesn't have to be wasted time.
It's just a page with a lot of small images (all directly loaded from the repo) and a short description for each. After loading half of the images GitHub throttled me and blocked requests with an error message about abuse.

But what if you want to overcome that discomfort, but haven't managed how to do so?
Nuclear energy is the Amiga of energy sources.

Ahead of its time, it was unjustly rejected and persecuted by the ignorant masses. Its advocates are bonded by the quiet pride that at least they weren't unthinkingly siding with those masses. (And they're right!) Meanwhile, as the Amiga stagnated for terribly unfair reasons, other, scrappier technologies like the i386 and UMG-Si grew from being worthless boondoggles (except in special circumstances, like spaceflight) to being actually far better and cheaper. But the Amiga advocates keep the faith, sharing their suffering and resentment. They inevitably try the alternatives a little and perhaps even start to like them. Gradually their denial recedes, decade by decade.

But they know that however much fab costs go down and leave their beloved Amiga behind in the dust, you'll never be able to run nuclear submarines and Antarctic research stations on solar panels.

Wind, where available, undercut the cost of steam power (including nuclear and coal) a decade ago, and PV undercut it in equatorial parts of the world about four years ago, or in even more of the world if you don't include storage. As a result, last year, China, whose electrical consumption has doubled in the last decade, built 48.2 gigawatts† of new photovoltaic capacity last year https://www.reuters.com/article/us-china-energy-climatechang... but only has, I think, something like 10 GW of nuclear plants under construction, scheduled to come online over the next several years. PV installed capacity in China is growing by 23% per year, the same rate it has been growing worldwide for the last few years; with some luck that will return to the 39%-yearly-worldwide-growth trend that has been the fairly consistent average over the last 28 years.‡

(A previous version was posted at https://news.ycombinator.com/item?id=26218673.)

______

† China's PV capacity factor seems to be only about 13%, so those 48 GWp probably work out to only about 6 GW average. It would be nice if China managed to site its new PV plants in places that could provide a capacity factor like California's 28%.

‡ Why 28? Because I haven't found figures yet on what worldwide installed capacity was in 01992 or earlier.

This sounds very familiar. In my final year at school I was given privileges to 'monitor' the school's computer lab over lunchtimes. What that amounted to was really just reminding the other students to save and leave before the afternoon lessons started.

I thought better and that I could automate this task by writing a small background task in VB (4 or 6, I can't remember which year/version) which would listen for commands on UDP.

One such command would initiate an immediate shutdown. Without prompting the user to save open documents.

Only once I issued that command to the entire lab.

I didn't take long for everyone to find out who did it since my own machine was still logged in and working.

The next day I removed the process from the machines lest I get myself in any real trouble.
Not really exceptional. Lots of these firms sell a dollar for 80 cents so becoming more popular increases their losses. The real question is whether this sort of delivery service is still popular when priced correctly.
The standard answer is "there's too much of a risk that an explosion would spread nuclear waste through the atmosphere". These days I'm not sure if it's true -- we've learned a lot about building containers which are safe even during rapid unscheduled disassemblies, and used them e.g. when sending nuclear powered rovers to Mars -- but that's the usual concern.
What would be even funnier is if it caused a stack overflow.

> in CPI terms

Any economic policy that changes prices can be seen as inflationary if you pick the right index. The CPI is not what matters. What matters (to workers) is the ratio of the CPI to wages. It doesn't matter if the CPI rises (temporarily) as long as wages rise faster. As long as you are not actually just printing new money, the system will eventually reach a new equilibrium where workers have more bargaining power than they do today and capital holders have less. That is an attainable policy goal. The problem is that that the moment capital has all the bargaining power, and capital wants low wages, so that's what we have. As I pointed out earlier, this is great if you're buying, not if you're selling.
That is the approach that I advocate as well. I believe that if you manage to carefully craft a path of comprehensible and enjoyable input of slowly increasing complexity you can speed up the learning process. I have been working for the past two years on creating such a thing for the Japanese language. You can check it out here if you are intested : https://drdru.github.io/ ).

However I don't agree with what you say about textbooks. Being able to read the rules of the language stated explicitly is definitely useful (once you have some familiarity with the language).
> nuclear power station design/building often takes decades and it seems like we have a shorter amount of time than that to make a significant difference.

It takes decades now, but we know hot to build them quickly and more efficiently. We’ve done it in the past.

Now, it is too late to avoid climate change anyway, and almost certainly too late to avoid crossing the +2 degrees threshold in a couple of decades. We are too late already.

But if we want to minimise the cascading issues that are heading our way, it’s not “let us do something or something else”. We need to redirect as much as we can of our industry to decarbonised energy. This means wind and solar and nuclear fission and hydrogen, and a whole bunch of R&D into the next steps for all of that (including nuclear fusion). Also, we need to consume less. Quite a lot less, in fact.
Those are awesome tools, that you!
