We don't have fusion that is even remotely practical so making a safety case for it is very difficult.

In general, fission is very safe and next generation fission plants in development are incredibly safe. To a point where you have to really be Micheal Bay to come up with a scenario where radiation is escaping the exclusion zone.

Germany does not have a safety problem, they have a culture problem. This is driven by a 70s anti-nuclear war agenda that basically makes civil nuclear plant = nuclear weapon argument. I have lived in Berlin and the amount of anti-nuclear nonsense you see there is amazing. Anti-nuclear foot mats are common.

Fusion is not a practical viable option in the next 2 decades likely more.

You can right now go to South Korea and order 10 1GWh nuclear plants for the next decade and probably much more. Germany could have started built nuclear 2 decades ago and they would be as or more carbon free then they are now.

Next generation fission plants are going threw regulatory process in a number of places and I am not informed on China. Canada is your best bet for a internationally recognized regulator to license an GenIV plant. The US is cooperating with Canada and hopefully will issue dual-licenses.

Most of these companies have a hard time getting money, the process could speed up if other countries really invested in this tech.

See the current state here:

https://nuclearsafety.gc.ca/eng/reactors/power-plants/pre-li...

The furthest along are Terrestrial Energy with a Molten Salt fast reactor. They have been in 'Phase 2' for a few almost 4 years now and should finish that relatively soon. This is the furthest along any non-research GenIV design has ever come as far as I know.

Hopefully by the end of this decade we will see some actually operating.

Technology wise this could have been done long ago, but the Canadian regulator is really the first to be so forward thinking. In the US non of this would have really been possible.
Same, sometime I get naughty ads, I wonder what impression it would leave on children mind. I think someone has uploaded the few examples of such egregious vice.

Not really. The real feature being asked for was to prevent arbitrary extensions from accessing the filesystem. That specific request has been granted, as WebExtensions cannot access the filesystem.

The situation that no other "safe" method of accessing the filesystem was not even considered by the bug's author, but it does address the issue.
Yeah, that’s what I’m wondering, too. I just posted an Ask HN on this.
We can, and we should, do both. Most of the money raised by MIT's ARC / SPARC project has not been taken away from wind and solar - it's extra money that people chose to invest because, financially, it looks like a decent gamble (or, in some cases, even without looking so profitable, but a step in the right direction, and some people value that).

I'm a big believer in wind and solar, although their intrinsically intermittent operation causes me to also worry about baseload power options, and nuclear fusion is the most attractive and promising development in that field.

I think it's stupid to look at one part of the solution and not at the other(s).
i think that real sanctions can do quite a lot - it would make a real difference, if state run enterprises like Gazprom and the big banks would no longer be able to mobilize any money on the markets. I actually do wonder, why measures such as a shutdown of swift have not been announced yet.
China did not, they even say western nations are responsible.
Fair point re clay foundations, but I was talking about the tooling choice for server-side rendering, not server-side rendering itself. For instance if they had implemented this in Erlang or Go they likely wouldn't have run into this GC bottleneck they had to engineer around to be able to exceed 50 requests per second.

I'm a big fan of server-side rendering and am sure it could be used way more often to great effect.
Well Nancy Pelosi & Husband use her political insider position to make money. So why not
What this boils down to is that he thinks a flat namespace (tags) offers advantages over hierarchical namespaces (tree). They really don't. Once your tag space grows you will start to struggle with naming, and path-like structures (nested namespaces) start to creep back in. And you are right where you started: paths.

The treatment of immutability is too superficial to make any sense of so I don't know what the author is imagining. Ted Nelson has evolved some ideas on this for decades that might be worth knowing about. Some of which have kind of come to pass (if you squint and look at how non-destructive editing tools for video and audio work, for instance). However, very little of Ted's thinking has ever been burdened by usable implementation.

The concept of having multiple references to the same file already exists. So what he proposes can be realized with existing file systems just by introducing a different naming scheme and making extensive use of sym-/hard-linking.

Yes, a lot of file systems will have terrible lookup and traversal performance, but that problem exists in an orthogonal universe and can be solved. Is, indeed solved, in some fileystems if the marketing blurb doesn't lie.

If you think about how you would realize this using existing filesystems, by organizing them differently, the concept isn't as sexy anymore. Because it doesn't really involve a lot of new stuff and you start to see the inconvenience of having to cope with both novelty and problems you didn't have before.

The problems someone like me wants solved in filsystems are entirely different, and aren't so much about filesystems as it is about how you make the functionality useful to applications.

For instance, there are filesystems that offer snapshot semantics. Including COW-snapshots. This would be useful whenever applications need to do be able to roll back changes, switch between states, do backups while being live etc. Yet I know of no language which has snapshot as part of the standard OS interface. So people generally don't write application that take full advantage of what the underlying system offers.
I took a quick glance at anafanafo and couldn't tell if porting to Go would be easy, since the structure seems slightly convoluted. Anyway, if the lookup table approach used by anafanafo isn't easy to implement, there's always the rendering approach, using something like Cairo. Code I whipped up in a few minutes:

package main

import (
"fmt"

"github.com/gotk3/gotk3/cairo"
)

var _cr *cairo.Context

func init() {
_cr = cairo.Create(cairo.CreateImageSurface(cairo.FORMAT_RGB24, 1000, 50))
_cr.SelectFontFace("Verdana", cairo.FONT_SLANT_NORMAL, cairo.FONT_WEIGHT_NORMAL)
_cr.SetFontSize(11)
}

func measureTextWidth(t string) float64 {
return _cr.TextExtents(t).Width
}

func main() {
measureAndPrint := func(t string) {
fmt.Println(t, measureTextWidth(t))
}
measureAndPrint("build")
// build 24.7177734375
measureAndPrint("passing")
// passing 39.767578125
}

Not sure if performance would be acceptable, though.
No military expert but it looks like they are following a pretty standard strategy of targeting and destroying air power throughout the country by bombing airports, radars, and air force facilities in general.

How far will their ground troops then go? We shall see...
Not dubious claims, misleading claims. ITER is designed with the goal of achieving Qplasma=10, which is energy break-even, but not electricity break-even, which as Sabine points out is at around Qplasma=20 (for ITER specifically, had it been designed to achieve electricity, in theory).

That Sabine has a point that some media outlets miscommunicated the Qtotal, it does not mean every article that does not mention Qtotal is somehow a scam. Qtotal is only relevant for project in which achieving a positive Qtotal is actually a goal, which it isn't for any of these projects.

What Sabine doesn't mention is what the theoretical limit of Qplasma actually is. ITER was explicitly designed for Qplasma>=10 to save costs. There's no other reason why Qplasma couldn't be higher. It's just money that is the limit.

People quoting Sabine should get this in their head, ITER was not designed for generating electricity. Its Qtotal is intentionally lower than 1. Yes there have been journalists who got important details in their articles wrong, but anyone who knows anything about these reactors is not being mislead by the ITER or JET experiments.
We live in Belgium, so it's not Biden she's been listening to.

And to be frank, I "saw it coming", but not that much more than her. I was maybe 50/50 on an attack up until yesterday.
If true, this probably is one of the most "important" dogfights since the end of the Vietnam War, or maybe since the Falklands War (I'm not so sure on this second one).
Good thing is it seems people are getting better at remembering who lied most and most recently. (Yes, that is me kind of implicitly admitting that the war against WMD in Iraq was based on lies. I want Nato but I don't want Afghanistan, Iraq etc.)

At this point, after https://en.wikipedia.org/wiki/Malaysia_Airlines_Flight_17 and after repeatedly saying they wouldn't invade Ukraine etc etc everyone should know that even if we don't always trust our own, Putin and those loyal to him are absolutely untrustworthy.
My response to these types of proposals is “just imagine that folders are tags and each level of hierarchy is a tag, symlink for multiple tags.”

It’s funny because the author just proposed a different, I think worse due to novelty and minimal benefit, organizing hierarchy.

I think Apple has a decent approach where their spotlight indexes very well (I use hit command+space and the first letter or two instead of navigating finder), and they support tagging files.

I cannot test your knowledge. For me you are just another account crying large-scale war. You present no evidence, other than a few observations, stories and a strong conviction of self-grandeur.

I'm not saying you are lying, being super intelligent or just exaggerating, but many people won't "just trust you". You should understand that.

> The owner retains control of nothing. From the instant you first seed to p2p, there is nothing you can do anymore to change what might happen next. You completely lose all agency over your own material. That is not "control".

(putting aside the fact that peertube is NOT A P2P distribution platform[1])

P2P is not different from any kind of distribution mechanism for digital content: the moment you put your content online, you've lost a good chunk of control over it since anyone can now download it a re-upload it elsewhere. This is automatic for p2p, but it also happen all the time on youtube, (or worse, porn tubes).

There is no way around it so far, and DRMs have largely failed preventing that. So any content creator must know this at this point: once you've published something online, you cannot reliably unpublish it.

Now, when you go through a centralized platform you also lose one more part of control: not only you cannot unpublish it, but you also cannot guarantee that it will remain published. This is the part of control you can get back by using peertube or other federated or distributed streaming system.

I think "malicious compliance" is sometimes a misnomer. I.e., when the goal is the common good rather then malice.
So being Russian is bad now? I don't think that is safe to assume that.

> In the light of recent development is it safe to assume that JetBrain products are not use for Russian espionage?

If you don't trust the software you are using, just don't use closed source software, use only free, open and libre software or compile it yourself. Since all closed source software is essentially 'malware'.

That is safe to assume.
Why the progress developing fusion power has been so slow
My point is that in all of those cases there were reasons behind the attacks. You are not calling Bush or Clinton crazy for what they did right? Same for Russians.

You are making a commonly seen mistake there.

Yes, making magnetic fields stronger can give one higher power density than ITER. But one runs into a limit because of power density at the wall. Once you're at that limit, higher magnetic fields don't really help.

ARC's volumetric thermal power density (volume of reactor, not of the plasma) is just 1/40th that of the primary reactor vessel of a commercial pressurized water fission reactor.

60% of the mass of an ARC reactor is in the steel structural supports for the magnets, so it's about at the upper limit for steady magnetic fields in a fusion reactor.
Yeah there are many idiosyncrasies to the British system, which make articles such as this one not so easy to fully understand if you're not well acquainted with the system...

There is also Nitter as a frontend. I love it!
For GMail I often used "non-folder tags" for example I would tag emails based on the to address and they were clearly marked in my inbox. Or I would tag certian types of emails so that I can review them later. For example SMS would be tagged, but I would read them in my inbox.

I just really wish GMail archiving was a tag. For example I get my video subscriptions into a tag called "Videos" but when I am done I remove the tag and that info was lost. It would be nice if Archiving was just adding an "Archived" tag and it was excluded from tag views by default. That way archiving doesn't forget all the tags. The only workaround I am aware of is making two tags for everything like Videos and Videos-Archive. Apply both in filters then just remove one once you are "done" with them.

Folders have the same problem. Of course trash systems work around this by explicitly recording the original location.
Off topic, but what is that circular border in south Kazakhstan? Map bug, or a mathematically inclined contested territory? I don't see it in Google Maps.
This is nice but for more mass adoption we'll need something seamless that will just be included as a script in a web page and "just work" by connecting to a provider while still customizable for people who want to use their own node.

It can even "polyfill" any IPFS paths automatically (which should just be simply as replacing any ipfs:// URIs with ipfs.io gateway paths).

For anyone trying to host pinned files behind a NAT/CGNAT would it be possible to hole punch to serve paths directly? If possible everything can me set up to work just out of the box with minimal/no setup in browser which should be the aim.

In other words, we need something of an IPFS version of what MetaMask/ethers.js did to Ethereum based blockchains.
And how did the entire world allowed itself to depend on China for... pretty much everything? Middle-eastern oil too.

It is globalization, which, in principle, is a good thing. Maybe nor for climate change since we are talking fossil fuels, but if a country has an abundance of resources, it would be a shame not to trade. If Russia needs the world and the world needs Russia, there is more chance for the conflict to end with diplomacy than by killing millions.
> As has been pointed out several times already, this is not a Boeing problem. It affects practically every major aircraft manufacturer.

1) I never stated the radar issue was only Boeing’s “problem” previously, I stated it’s yet another example of a mess they are in which ultimately boils back to a “move fast and break things” attitude being a major cause (just in this case, it was more the FCC to blame for that attitude)

2) It ultimately is their problem to solve for the airframes they sold however, whether it was their fault or not.

> If anything, Boeing has been very proactive about identifying the affected equipment well before any accidents happen. This is precisely what they should be doing.

Link to the ADs from Boeing saying which models are susceptible? I hadn’t seen that
It is only very stupid people who believe their enemies are stupid.
If Putin attempts war against a NATO country, e.g. Lithuania, my only hope is that NATO will stand together and respond with forces on the ground. If he escalates to use nuclear weapons, he's a fool and I hope the Russian people will tear him to pieces in the street before he condemns them to death.
Fission is being built at all only for political reasons. People who build power plants on their own dime are shunning the technology. No merchant nuclear power plant selling into a competitive market has ever been built anywhere.
I would have thought the last sentence of my comment would have been enough of a signifier.
No, the 5G transmitters are in their designated spec, and 200Mhz away from the altimeter frequencies. The problem is that the radio altimeters might not have proper filtering, which wasn't a problem in the past because the spectrum now allocated to 5G was not seeing much powerful transmissions.

The radio altimeters are fully up to spec, but the spec does not say enough about filtering out signals outside of the required band. This oversight in the spec was never much of an issue because of the aforementioned lack of usage in the spectrum before 5G.
I think its a bit disingenuous to call the PCP analogs "hallucinogens"

They're NMDA antagonists primarily, the same primary mechanism as ketamine. They're dissociatives
Hey there! Nice work, looks great!
I've built a few of these and the biggest concern with those motors (I've tried them before) is that they aren't made to handle the torque of even small hills. They'll burn out on mile 25. It's not the wattage that's the problem, they just start to slip and burn out unless you gear them down a lot, but then you lose a lot of their speed. Maybe I've just always bought cheap stuff. Also worried about the tension on the chain, is it adjustable?
I also had trouble with XT90 in the past. I would melt them. Proper soldiering iron fixed that.
Nice build! It's super unique!
> I want my phone to be reliable and receive updates for a long time.

The only way to ensure that if to publish the complete datasheets so that operating systems can maintain drivers. You cannot rely on a hardware manufacturer to provide updates, as it could go out of business any day.

> If more glue makes the phone more resistant to water damage or breakage when I drop it then that is better for me.

There's plenty of hardware design techniques (disclaimer: not my field) you can use for structural integrity and you don't need glue. Even if you don't have intention to take it apart, if it's glued it probably means that it will be really hard to replace the battery when it dies after 2-5 years.

If you want durable hardware, you need hardware that you (or a skilled shopperson) can take apart and where you can replace individual parts. That's why cars can 100% be taken down and why electronics in cars (over 100 microprocessors in an average car?!) are a worrying development for maintainability/durability.
> I'm not saying you are lying, being super intelligent or just exaggerating, but many people won't "just trust you". You should understand that.

I don't ask you to trust me. I ask HN readers to listen to their own countries' military experts.

Your generals who spent half their life studying Russian, and Chinese militaries in Westpoint, Saint-Cur and Sandhurst didn't do that for nothing.
Sapir-Whorf hypothesis has met its match. German obesity is on the rise: https://en.m.wikipedia.org/wiki/Obesity_in_Germany
Yeah, there are no guilt-free answers when it comes to base load generation, and fission is no exception.

But when the plants already exist and you shut them down because the Japanese decided to build one in a tsunami-prone seismic zone, hire a corrupt organization to operate it well beyond its intended service life, and install backup generators in the basement, or because the Soviets built one and operated it under the "Hold my vodka and watch THIS" school of engineering, well... those just aren't good reasons, and also not the kind of thinking I expect from the Germans.

France's modern plants should help, but they won't come online for years.
How about having an off switch on one side and an on switch on the other, then we can fight it out by seeing how many goes for each?

Or, make in a flappy bird game? One up and one down button.
My point wasn't that it would be impossible to create a new kind of solution. It's enough that it would be a massive undertaking for unclear benefit, if any.

If we get rid of hierarchical filesystems, what replaces got, for instance? Perforce has some ability to project different filesystem hierarchies, but even if that were enough (it probably isn't), porting all those tools and projects to perforce would be an incredible amount of work without a clear upside for users of version control systems.
Nope, this is good news.

JET is a 1980s research project into how to contain a plasma and squish it enough to achieve fusion at all, not a practical generator. It doesn't have superconducting magnets, it runs on big lumps of copper, with limited cooling and no way of recovering output power.

In the latest run, they achieved fusion and kept it running until JET ran out of power for its magnets. The plasma didn't touch the reactor walls, didn't destabilize, didn't crap out in any of the numerous other ways. They had to shut it down before it overheated and burned out.

(I've been reading reports for a while about the use of massive amounts of computer power -- and deep learning -- being necessarily to stabilize plasma in a reactor. That seems to be what this demonstrates.)

This is probably JET's swan song. They've pushed it as far as it can go; also, the D-T reaction produces surplus neutrons so tends to generate radioactive waste via secondary irradiation of the reactor core -- which makes it hard to get inside and fiddle with it.
I actually had an idea for a similar site, with that plus the ability to show with the markers which cardinal direction is being recorded.
> You do not have this attachment at all in any modern MMO were most people just click through the cinematics.

I have a bit of the opposite opinion. The story in WoW for me felt very half-baked. I wanted to read the quest text, but usually it was kind of dull. The overarching story was at once overly complicated and a boring mess. Despite putting hundreds of hours into that game, I don’t think I really care about any of the characters in the story.

In comparison, the writing in FFXIV (another, more recent MMO) is a masterpiece. I cried several times through the main story quest. I don’t think I’ve ever cried before in a video game. Unfortunately the best writing is the most recent part of the story - and to get to it you need to play all the previous expansions first.

But World of Warcraft makes much better use of its world. Especially before they added flying, the world really felt like a place you explored and were present in. It has geography, that you need to learn as you play. And it takes time to move from place to place. WoW really invites a sense of wonder and curiosity as you explore the world. There’s always something interesting over the next ridge. And it might be a monster that eats you. It was a delight.

Despite its rough edges, wow is still a work of art. I’d love to work on something like that at some point in my career.
