Nuclear's economy of scale is not at all "basically zero" even with traditional PWR reactors. Here's a graph of nuclear plant cost relative to construction year: https://ars.els-cdn.com/content/image/1-s2.0-S03014215163001... [1]

There's a big cluster of plants built for 1-2 billion per GW during the late 60s and early 70s. That's nuclear's economy of scale.

UK is currently building new nuclear. Can’t think of anywhere else.

For me people seem to have an either or opinion - we should build renewables or nuclear or whatever (I don’t think this is your stance though).

Reality is that we should be deploying none CO2 producing energy as quickly as possible, and if that means building solar / wind farms then build them, if we can build nuclear then build it.

Hopefully politics will enable future low risk low waste etc nuclear to thrive.
"A Tesla Model 3 gets 4miles per kWh"

At cruising speed, I assume? Delivery is going to be radically worse, because it has a ton of start and stop operation, the worst case for consumption.

You also seem to be spec'ing what it looks like for a post office to recharge one vehicle. What about dozens, plural? A current post office needs only marginally greater power than a residence. Charging dozens of electric vehicles is going to need more than that.
Yes and no.

Yes: you need to cool the water down to increase the efficiency of a steam engine / traditional thermal power plant. For many plants, this is a supply of fresh water.

No: A desert environment is obviously hostile to fresh water (like a stream). As such, "cooling the water" is solved through other means.

https://en.wikipedia.org/wiki/Ivanpah_Solar_Power_Facility

In the case of Ivanpah Solar Power (the first Thermal Solar Plant that popped up in my search), they air-cool the water in a closed system. It won't get as cold as stream-water, but it still gets cold-enough that they can recycle / extract energy out of the steam engine system they use.
I think the biggest problem for humans is not the loss of our coastal cities as devestating as that may be but what happens to our food.

Java is used all over the place for various backend applications, e.g. data processing, web backends. It's fast, well documented and has a great standard library and ecosystem. In many of these applications you control the deployment environment, so making sure that your container has the JVM isn't an issue.
I believe that Swarm and the other enterprise-oriented pieces all went to Mirantis. Docker, the company, is now specifically oriented to developers.
I think it's a combination of:

* extremely, extremely thin margins

* in general, users are pretty low-discretion, which makes it hard to meaningfully differentiate your product

* deeply entrenched competition (what % of laptops are sold at best buy/etc?)

* the users who are high-discretion are going to be extremely demanding users. They're going to nitpick over small details in both hardware and software. And they're probably going to be installing their own OS (or at least reinstalling the existing one) and will generally be more demanding of both product design and support. Also, they probably have the tech skills to correctly point the finger at you when it's your fault. Whereas less discerning users might just go "Ugh bill gates!"

Doesn't help that the "linux laptop" niche was probably a big part of this "niche laptop" market segment and Dell and Lenovo are both kinda warming back up to that niche. e.g. the newest XPS's all work great on (latest kernel) linux.
I don't understand the appeal for System76. It seems grossly overpriced. Is it simply because they install Linux for you? You can find the same processor with much better specs for cheaper on Amazon or Costco.
This is a story because it's fashionable to hate on China. This has been going on in the US for years already. Using terms like CAID without an explanation to what it is makes the reader scared that China has somehow been able to infiltrate iOS to track users, this is bad journalism. CAID is a simple advertising id used across apps, there is no hacking of iOS or an incredible technical prowess on the the side of China that we should all be afraid of, etc.

The term "state-backed" in the title should be removed, HN is not a political battleground.
It's useful to know what people are thinking when they are the ones making meaningful decisions. Even if you don't trust them to be honest (which I don't think is a valid criticism here, there's not much in the quoted text that could be construed as "lying"), if you want to take issue with their actions in the future or have insight into what they may/may not do it's useful to get something from the horse's mouth.
>YouTube and Twitter simply have no bone to pick with them and would rather stay out of the fight by complying without objections.

Which is fine, they wish to operate a legal business. But they are going out of their way to create their own system that is more stringent than the law.

>TL;DR: A half page automated email from a content owner has to be acted on expeditiously, can only be overturned with a lawsuit, and there's no penalty for abusing the system.

Per the outline in Wikipedia, Alice does not need to file a lawsuit to get the material reinstated, only send a counterclaim letter, similar to the claim letter sent by the content holder. If the content holder wishes to contest further, they must file a lawsuit, otherwise after 14 days the material may be put back up.

>there's no penalty for abusing the system.

No and that is a problem.

I am not very familiar with the red flag system and there did not seem to be a good description at a glance. My guess would be that if your system is used/ is promoted as enabling infringement, then you may be liable. Like MegaUpload was.

The reason that Youtube and Twitter go above and beyond the law is simple, it gives them more power and they view being content owners as their next step so they are doing what they can to consolidate power on that front. We should not give them a pass for this behavior.

I'd argue that all music-streaming services have very little pricing power!

Streaming services rely on being an easier/friction-free option as opposed to piracy (or alternatively, buying the copies directly from the musicians).

Your point is still valid though, the competition is still fierce; Amazon, Tidal, Apple.. etc.

Perhaps there should be legal escape hatches from HOA rules specifically for energy efficiency upgrades. I don't generally advocate for centralization of power (ie, a state imposing its will on a community), but in the case of climate change I'll happily make exceptions.

Stop re-writing pipelines Why GitHub Actions drive the future of CI/CD
There are suspension systems, heating/AC, doors, sunroofs, motors controlling windows and doors, sealants around the same, lights, infotainment systems, seats and seat controls and motors controlling these, power steering, heat pumps, multiple cameras (each of which can fail), huge numbers of sensors (including radar), as well as wiring between the cameras and sensors and all other other components, differentials, brakes, brake regeneration, transmission (yes, Tesla has a transmission, just a simple one), engine, and battery.

All of these can suffer failure and require replacing. Even if they are unlikely to wear out in normal circumstances, people get into fender benders, and there are always exceptional circumstances. Given the huge number of parts and miles of wiring, the average owner can expect exceptional failures on a few parts. All modern cars are extremely complex, even if the drivetrain is simplified.

> an induction cook top

You make it sound like you're using a lot of power in that bus, but an induction cook top is at most 2-3 KW. That is 4 horse power. If you want to crawl at 5 mph that might be enough (but not for a skoolie anyway).

Cars have a huge power-plant under the hood. 100kW per car, at least. All the cars in a city have far more power than the power plant that supplies the city. Think 10k cars (town)= 1 GW. That is a nuclear reactor...

All the cars in the US, 275 million vehicles, at an average of 100KW, have a combined power of 27.5 TW. The total installed electrical power plants in the US are around 0.5 TW. The whole world has only 6 TW of installed power plants.

Cars need a lot of power...

Sure the above wont work for everybody, but if you are like me, you unpacked the laptop at home and at work each day at exactly the same space, where all the cables and extra monitors were.

I used to use laptop in coffee shops and outdoors, but nowadays between phone, and tablets (wel phone and kindle in my case) I almost never feel the need.

Buy silent box, mobo for overclocking and underclock it for extra silence, and throw the box under the table.

Still have my laptop, but its mostly just "backup" and in case I travel somewhere, but honestly I don't care about it as much
Trade-offs and Triumphs 33 by Jenny Kim
Good questions. Chris here. Before learning about the space through user interviews (and from Neil and Randy), I had the same thoughts!

For companies that want to build this internally, there's a couple of things to think of from an engineering perspective. A) Restore state: If users can manipulate data in the app, is there a "restore state" so that they don't modify the same data for other visitors. B) Privileges: you probably want special, more-restrictive privileges for users just experiencing a demo and not setting up a typical user account.

So you are correct, that setting up a static version of a team's app could solve these problems and that's exactly what we help facilitate! It's a trickier problem to implement internally than you might initially think (imagine calling "indeterministic" web APIs like Date.now() for a time-series chart or Math.random() for uuids.) Through our customer interviews, we found that it's difficult to win the engineering team's time for such a task.

Our no-code editor also allows you to update the overlays dynamically and easily update the (now) static demo to keep it up-to-date with your application.
> Never mind memories; there are parts of our eyes that aren’t responsive to light at all. We’re always hallucinating.

Are you referring to the blind spot, or something else?

Interestingly, the blind spot turns out not to be a design requirement, it is a contingent feature that cephalopods like octopuses (whose eyes evolved independently from vertebrates') don't have.
> They probably did this for speed. Faster than library calls or system calls.

Xorshift is faster than RDRAND and json-c is using lookup3 for hashing (unless I'm missing some other use of the RDRAND data) so it doesn't need cryptographic RNG.

> Apparently too hard for the clowns at AMD. AFAIK it's a "solved problem" on Intel hardware. (Has there ever been a problem with the hardware in any Intel CPU?)

Meltdown/Spectre of course. As I posted earlier there's also an Intel microcode update that makes RDRAND much slower. https://www.phoronix.com/scan.php?page=news_item&px=RdRand-3...
That reminds me... I was converting some VHS tapes for a family member and one was of an event on a farm where a trailer had tipped over in a slope damaging something on the axel.

Cut to a short time later and the clip continues with the farmers welding and repairing using logs to prop up parts of it.

They would have been seriously impacted if they needed too wait for days/weeks for a appointment to have it repaired.

There is no excuse for having something not be repairable, especially if you have the knowledge and need to be able to repair your things.

It's not clear what you're saying here, other than concluding that the disclaimer in question is racist (despite the fact that people who can't pass as white males, at least in the US, quite frequently report a difficult experience---even those who are successful).

Do you think that having the internet, libraries, and universities is the only thing that can make it easier to learn technology? Does having time factor into that? Time to use the internet, time to go to the library, time to study for university. If having time factors into it, would you consider that having money factors into having time? If having money factors into having time, would you consider that race often factors into having money? If you would say that race may factor into having money, would you consider that this may be due to systemic effects? And if you would grant that there may be such systemic effects, do you think these effects may persist to some extent even for those who do manage to learn tech? Obviously there are a lot of links in that chain, and you may disagree with more than one of them, but I'd be interested in which link in the chain breaks---or if you're trying to say something beyond this chain.

I'm interested in the “quite the reverse” note, as well---what are some examples of countries in the world with a white minority where the country in question plots to hinder white peoples' learning of technology?
Boosting developer success on Google Play
Just to get you an idea of how wrongheaded this entire thing was, I have a personal anecdote relating to this shitstorm.

Back in autumn 2013 I got a letter stating that I had received too much in child care benefits, with a request to pay it back. On the back of said letter was the text 'If you are still entitled to child care benefits and want to settle this amount against upcoming entitlements, you do not have to do anything'. Given as I was still entitled to benefits, I proceeded to not do anything. A few weeks later I got a reminder, once again stating that if I wanted to settle, I wouldn't have to do a thing. The reminder was followed by a final notice with opportunity to pay, once again with the exact same text on the back of the letter. So, obviously, I once again did nothing.

Then we got a 'Dwangbevel in naam des konings', i.e. a writ of execution in the name of the king. Red envelope. No added text. So I had to pay up. Now, as you may well guess, the tax service had already also started settling against the benefits that I was still entitled to! This prompted me to write a strongly worded letter, asking the tax service in no unclear language what I should have done differently, and requesting them to not dock me for that particular money twice. Literally the only reaction to that letter from the tax service was in silently restituting to me the double payment.

Now, I'm a reasonably well paid and well educated software developer, who just happens to hold two nationalities. I am perfectly sure that I would not even have had a reminder had I just had the Dutch nationality.

I could have paid in the first place and not settled against upcoming benefits; I was just lazy. However, imagine you're scraping by on minimum wage and are put in such a situation. There is no other way you could have acted than I did, but you also would not have been able to pay up to the writ of execution. And there would have been no recourse!

Add to that the fact that in many cases, the people hadn't even actually been paid too much, as I had, but merely been tagged as possibly fraudulent and put in to the system for reclaiming paid benefits, so the government could take a stance of being hard against benefits fraud while figuring out if any fraud had taken place in the first place.
> Therefore the only cost estimate we can rely on is what we have actually managed thus far.

Correct. And we've managed to bring the cost of nuclear down to 1-2 billion dollars per GW when building plants at scale [1]. This was done during the late 60s and early 70s when we built lots of nuclear plants at once [2].

Your example is a little specious in that a bookcase is very different from a song. The production of one has huge economies of scale, whereas a song doesn't. I agree that producing things competitively is important to improve overall efficiency, but with the music industry you really have a small cartel of massive labels dictating the terms for everyone else (ie. engaging in massively anti-competitive behavior). It seems weird to me that your pro-market ideology leads you to support what (to me) seems to be more or less wage-fixing for a labor supplier (musicians)
It’s sad but true: seeing your “investment” based on youtuber lose 90% of its value in a crash is the only true way to learn how the world works.
Yeah. I've said it before, if you do a like-for-like comparison (of notebooks, I've found this to be less true on their desktops) then their prices are often in line with other manufacturers. Every time I've bought a MBP (2007, 2009, 2012, 2017) I've done a comparison with non-Apple laptops and found that a spec-for-spec equivalent from most manufacturers is going to be roughly equivalent in price to Apple's (usually a range of about $300-400 on the prices, Apple being near the top but not always the top).

Now, if you spec out their Mac Pro, especially as it gets updated so infrequently, those get very out of line with competitor hardware quickly.
