Would that not be impossible because of the lack of effective cooling in space? The only way to get rid of heat in space is by radiation, which is a very inefficient process. Assuming temperatures cannot rise above 100°C, every square meter of radiator fin emits at most a kilowatt. And because half the orbit is spent in direct sunlight, a significant part of the surface area will have to be reflective, making it useless for radiating heat.

Also, where'd you get the power? Solar panels will only yield a kilowatt per square meter at most, for half of the orbit. Beam it up from Earth?

It absolutely is the definition of rent-seeking. That doesn't make it bad.

If I wrote a book, government grants me a limited monopoly on production of that book, and I can collect rent (in an economic sense) from anyone who wants to reproduce that book. That's a good thing.

A difference comes in that with land, the underlying resource is limited. With books, it isn't. We're both collecting rents, but on something different. That difference translates into why it's helpful to incentivize writing books, but not helpful to incentivize consolidation of land among a few landlords.

Over time, the two converge, though. If copyright still applied to works from 1500, it would be crippling to society. People couldn't build from a collective intellectual commons, since it'd all be locked up. The people who collected rents on those works would have less incentive to work, not more, despite having no relation to their creation. Whoever owned the rights to the work of de Vinci would have tremendous income based on no contribution to society. It would create a new feudalism or nobility.

That's why the copyright and patent clause in the US Constitution guarantees copyrights and patents only for a limited term.

Rent-collecting on Mickey Mouse works incentivized Walt Disney to create Mickey. That was a obviously a good thing. Rent-collecting on Mickey Mouse now a century later isn't incentivizing anything except for extra profits to a megacorp, and limiting others' ability to build off of Walt's work. That's obviously a bad thing.

If you build a SaaS, and you collect rent from it, more power to you. If your grandchildren's grandchildren don't need to work because they're still collecting rent, we've messed something up.

TL;DR: rent seeking != parasitic. Both are distinct economic concepts.
Agreed. Ironic that this happened so soon after my recommendation.

Fortunately for me, the new Micro plan works fine, but at this point, I think services like Mailbox.org might provide greater value compared to the upper tiers.

> The only possible way to stop it, is to continue advancing computing power according to Moore's Law

No, economies of scale will always result in some services being cheaper to centralize.

I think the same will happen with 3D printing and solar panels. No matter how cheap they get, it's always even cheaper for the power company to build a huge solar farm, or for me to order a printed part online and have it shipped. (For small batches anyway)

Services like search and speech recognition and translation that benefit from having large datasets to work with, also need fast Internet connections to keep that data updated.

So in 2020 my $100 might buy as much CPU as Google's $80, but it only buys as much network transfer as Google's $10.

The ratio is probably worse if you consider that self-hosted or even federated search means all the web scraping has to be replicated to 100x or 1,000x more databases than Google has to manage even with their CDNs. Redundancy is not free.

I want it to work too, but I don't think centralization is a technical problem with a technical solution. We're fighting uphill against a law of economics. Not even capitalism, either, economics itself as a law of nature.
I thought it was pretty interesting to see that Linus was focusing on power + silence. Made me interested in picking up some quieter fans for my PC.
At the very best then, it'd be the way he said it (so, the phrasing) combined with the fact he's the president (or was running to be), a role which we expect not only the highest levels of decorum but also humility and respect for the citizens, and combined with the fact that just because Drake might do it, it doesn't mean it's an OK thing to do. I don't know about other people, but I'd definitely criticize anyone for not only using their status to grope people, but then to brag about it. To brag about it betrays a certain mindset and characteristic of disrespect for people, and in this case, women.

In other words, I'd think lesser of my friend for saying something like that to me, or overhearing him in another conversation. The same goes doubly for the leader of the most powerful nation on the planet.

The school officials have decided to do remote schooling.

Fully 50% of the students have no internet at all.

Another 30% have internet that is incapable of remote.

You might say that they're too poor. And that is part of it. But there are plenty of people with lots of money in DC and the surrounding area that would be interested in moving here or having a vacation cabin, but cannot buy internet access for any amount of money. It just doesn't exist.

The communication laws desperately need an upgrade from the 1930s laws on the books that regulate everything like it is a telephone invented in the 1800s.

I agree. I fear people look at this situation in a different light than say the current president of the United States who, while he does have an email address, admittely does not write emails or read them directly. Knuth is admired and this is a pleasant quirk; the POTUS appears an old, out-of-touch dinosaur.

I'm not judging either; my initial thoughts were just of the different perceptions for similar unique and rare circumstances.
Making space flight cheaper and more reliable certainly helps advance human knowledge in my opinion.

>>time dialation (something completely alien to all before him

>Hendrik Lorentz prop

Lorentz did not think that time actually dilated; his notion of "local time" he considered purely a mathematical trick, unrelated to actual physics, in the same manner that renormalization sweeps away infinities in a clever manner.

Here's the quote: "While for Lorentz length contraction was a real physical effect, he considered the time transformation only as a heuristic working hypothesis and a mathematical stipulation to simplify the calculation from the resting to a "fictitious" moving system. " [1]

So no, Lorentz absolutely did not think physical time actually dilated. Stop repeating this nonsense.

Also, Lorentz was not the first to publish the time dilation formula. And, like Lorentz, all before him thought it a neat mathematical trick, devoid of actual physics.

Poincare did think it may be actual time dilation, but he too lacked the insights that Einstein had that put these dilation and stretching concepts not as ad-hoc after effects, but that they come from a simple, single physical principle. What's more, Einstein's way of looking at it all was the one that turned out to match reality the best.

For example, in 1905 Poincare introduced "Poincare stresses", another fictitious set of forces, to reconcile the math they didn't like from what they thought of as reality.

Lorentz and Poincare used the now-disproven aether as the basis for their theories. Einstein did not.

Spend a moment reading that wiki page, replete with sources, and especially the section on "The shift to relativity." It's abundantly clear that Einstein was the first to publish the correct interpretation, devoid of all the ad hoc (and physically incorrect) assumptions that Lorentz, Poincare, and others, used to reconcile their belief with the evidence. Einstein, in one simple argument, showed that one simple physical idea - light has the same speed regardless of observer - leads to the correct equations that model reality, needs no other ad hoc forces or aether or any other items.

Here's [2] notes from a talk I gave (and still give from time to time) on a simple derivation of all these things from the one principle.

You spend an incredible amount of time misrepresenting and discounting the work of Einstein, so much so that you're posting many, many wrong items. I gave up listing them since the sheer amount of it baffling. Why?

2% is trivial. They lost 2% of information (as someone pointed out this might be closer to 20%). This means the cost to the astronomer was 2% (or 20%). Calling this "ruining" is an exaggeration. Of course it would ruin a pretty picture, but "This isn't about people taking pretty pictures, this is about people trying to do actual work." where you can choose the part of information you take into account.
In the phrase “rent seeking” the word "rent" does not refer specifically to payment on a lease but rather to Adam Smith's division of incomes into profit, wage, and rent.
I didn't say people don't care. Issues like crashing app is exactly what people care about and where you should focus your time (or the data plan example). My point was people don't know or care about underlying data formats, so don't worry about that unless it affects the real user workflow.

More funding is good. Although of the 625m at the nat labs contractors like Battelle will take ~300m or more.

This type of feast/famine short term topical funding is usually a disaster. Investigators will pursue the money, trying to shoehorn whatever they're previous pet project was, then the funding will dry up and the main net effect will be some shallow projects. Renewable grants are the blood of science.

A single center openly funding as many investigators as possible for 10 years would be much more effective.
You're right, not all food intolerance tests are the same. For example lactose intolerance tests are pretty accurate but fructose intolerance tests are not as reliable, and need more studies.

One thing this doesn't account for is fraudulent delivery reports. In my area a large percentage of my USPS deliveries are reported as delivered around 6pm on the scheduled delivery day, but I can't find the package anywhere. Then it suddenly turns up the next day. People on NextDoor also report seeing this regularly.
I think he explains pretty clearly up front why his job makes this circumstance appropriate - on the bottom of things. I can’t think of anyone who should be more on top of things than a president.
The problem with comparing to a lot of other countries, is that the US really has remote locations.

In those situations, their "competitors" largely just drop off their packages to USPS and let them handle the costly trip.

You have ultimate control over free software, but the costs of maintenance become yours. Take some of the money you're saving from not purchasing proprietary software licenses and pay whoever you want to manage the complexity for you.

I will concede that in the context of personal-use software this is less applicable than, say, in a business context, but it's still applicable.

While I greatly admire Knuth, I've never thought he wasn't a dinosaur. I don't look down on my grandmother for being confused when she's trying to use email, and I don't look down on Knuth for abandoning it in the 90s.

I guess it comes down to whether you think technological dinosaur is an insult or an observation.
Absolutely but the Monash app helps with the process, at least in my case.
I think it'll be nicely self regulated. It's expensive to run, those that are not profitable will not be able to maintain their network and being in low orbit, those satellites will fall into the sky and burn up.

I'm fan of heavy key mapping customization to boost productivity.

The most productive remapping so far which I made is to globally remap (via xkb) Left Alt + HJKL to respective arrow keys. Works in all GUI applications which rely on arrow keys for navigation, plus standard Ctrl + Shift + Left Alt + H (Left Arrow) works to select previous word in text fields (e.g. in browser).

Next one is to remap Left Ctrl to Left Shift and to press it with upper side of the palm just below pinky (not sure how this part of the hand is called correctly) instead of utilizing finger for that. Works best on mechanical keyboards without bevels.

Also I find quite useful to remap keys 5-0 to Right Shift + Q (5), W (6), E (7), R (8), D (9), F (0). I find these keys are easier to reach and type without a mistake instead of using standard 5-0 keys which you should stretch your fingers to type.
For example, to type "()" I use Left Ctrl (remapped to Shift) + Right Shift + D, F which is easier to type without fingers leaving home row.

I think what Knuth means here is that he has consumed enough information in his life that he has now stopped consuming any more of it and is only generating new information instead.
I'm guessing they might mean fruits that can or need to be stored after harvest. E.g. there's various kinds of apples and pears that ripen after harvest - some of them quickly, some of them take months and are good throughout the winter into spring.
> Linux is explicitly on their radar. What do you think Android or Chromebooks are?

Android and Chromebooks don't intrinsically get you the content either. They just tend to run on hardware that's supported or include closed source components for big chunks of their graphics systems and management engines including chains of trust that are signed as being the code the other sections expect.

The average desktop Linux system has no interest in that, so it doesn't happen.
I think that's a valid point that needs to be made in this conversation, and it's super-sad that somebody downvoted you for it.

I've spent much of my career writing low-level code in low-level languages because I had to, usually in C and usually because I was in resource-constrained environments where tight control over CPU and memory footprints was necessary. There's absolutely room for languages that improve programmers' lives in that kind of environment while remaining suitable to that purpose. I'd put Zig in that category, and I find much to admire in it.

However, outside that domain, once you have even a little freedom from those constraints, it makes no sense to use a language designed around them. When even something as simple as manipulating a few strings or updating objects in a map/hash/dictionary requires careful attention to avoid memory leaks or excessive copying, and your code is doing those things a lot, you're using the wrong language. A language that "protects" you by guiding you toward adding the right boilerplate in the right places honestly isn't much of a help. Most code should be written in a truly higher level language, where things like circular references don't require much discussion except by the language implementors. The problem of how to do that without going full-GC and having to deal with pauses is where people should focus their attention, not more languages that just change which ceremony you must adhere to.
You don't represent stupid people, you make money on them taking advantage of the monopoly, you don't care about their interests. And they aren't as dysfunctional as you want to make them look like, they don't need to figure out everything by themselves, they can understand what they hear.
I mean...if this were any other business, someone clicking the wrong button and then someone else not catching this error would maybe mean someone's account was accidentally closed, or someone receiving a free pizza, or whatever.

The IT systems within banks are more or less the same as IT systems anywhere. Just as advanced, just as crappy. The difference is that if there is a human error with banking software, you're not sending free pizza, you accidentally pay ouy $900,000,000.

OK, it was a limitation of HDMI, and most devices still use that old HDMI standard, so practically it still is a limitation until the new HDMI versions are more common. On my monitors, I use DP whenever I can.
> Sometimes you do not want to be burdened by the limitations of a "high-level" language.

I see very few people suffering from such burdens, but a great many suffering from its exact opposite: using a low- or mid-level language to write hundreds of lines where ten lines in a higher-level language would suffice and be more easily verified as correct.
SpaceX is lowering satellite launch cost by 90% for anyone, Chinese or otherwise.

I cannot fathom how anybody could either come up with the idea of taking screenshots from a computer desktop continuously whilst working for a client (in order to somewhat _prove_ productivity, I assume) or is comfortable to a degree with a contracting company taking screenshots from a computer while working for a client.

Really, I can't grasp the absurdity of some people's mind sometimes and wonder about their morality (UpWorks in this case, not yours. Just to be clear.). Not everything that maybe is technically doable is also ethical. If you comply to such practices, I think it will have an impact on your self-esteem and self-respect. Just try to imagine how other fellow hackers, developers or software engineers you admire would think of the idea getting screenshot'ed every other minute in order to control them.
