D + D -> 3He + n is actually tolerable, since the neutron is of low energy. In particular, it has a much lower cross section for (n,p) and (n,alpha) reactions in the reactor structure. Those are the really serious reactions that ruin the material by filling it with microscopic very high pressure gas bubbles.

What you want to avoid is D + T on the T generated from the other D + D reaction. In Helion's scheme, I believe the ions do not equilibrate during a pulse, so that tritium doesn't slow down before the plasma reexpands and is exhausted to the divertor. The DT fusion cross section peaks around a 60 keV center of mass energy, so keeping the T energetic can reduce its fusion rate somewhat.

This is another reason to have "field reactors" burning 3He generated elsewhere, with a high 3He/D ratio. The lower D concentration reduces DD reactions, but it also reduces DT reactions on any T that are produced.

There's an additional problem of purifying and reusing the D in the exhaust of the machines. You don't want to have to filter out all the tritium from this before every cycle. It's possible the field machines could have many go-arounds of this gas before sending the sufficiently contaminated D back to be filtered (or used in the dirty DD machines).
You're asking for an example of cancel culture?

I was in Berlin for the last World Cup. It was delightful
to experience it like that.

This time I tracked it and really enjoyed the whole thing. The finals was the only game I was able watch in full and it was everything I hoped it would be.

Argentina’s second goal was just the best.
Argentina Wins also would have been fine. The whole world knows what’s happening today.
> he just lied. But why?

Because lying helped further his narrative in the public which is advantageous to him. Similar to how he lied for years about FSD.
I watched the video the other day when it came out and he interviewed several people that invested between 10k and 500k into the project. Seems like all those folks got taken up by the hype but the part I just can't wrap my head around is even then, how do you just dump that much money into something without any due diligence.

All the "due dillegence" that these guys seemed to have done is: "well Logan is rich and famous so this must be legit". I would have a hard time investing $50 of my own money just based off that, I don't know how you can convince yourself that investing thousands into this one crypto project is a good idea.
One mustn't use the term "busy body" because it is ableist. Some people do not have bodies, but are ghosts floating upon the ether. Also, it is too often applied to us here in the Department of Thumb Twiddling and it hurts our feelings. Instead use the term "insufferable twatwaffle".
The PCB can be prepared with KiCad or Eagle for example. Then you do a lot of preparation work. You have to prepare the bill of materials, be super careful about the annotation layers on the PCB to prepare a PDF of the components.

Finally you pay. :) PCB assembly services exist from various places, for example Seeedstudio is very reliable but pretty expensive. Note that different factories have different formats for the BOM and annotation PDFs.

> The mental contortions required to conclude that "committed suicide" trivializes something, but "died by suicide" doesn't, are so extreme that I cannot believe anyone honestly holds that opinion.

I think the notion is that "committed suicide" is like "committed a crime" and harkens back to the Christian notion that suicide is a crime (against God). And so it's moralizing language that blames the person for killing themselves.

You can verify that this is a common notion among people who work in the field by Googling. For example, the first hit when I search for "why shouldn't we say committed suicide" is https://www.irmi.com/articles/expert-commentary/language-mat... which says:

> For example, the phrase "committed suicide" is frowned on because it harks back to an era when suicide was considered a sin or a crime. Think about the times when we use the word "commit": "commit adultery" or "commit murder."

> That leaves as the most likely conclusion that this document is not an honest effort to eliminate 'harm', but a mine-field, a list of sins and prohibitions, to be used as ammo against opponents.

It's interesting that you arrived at this conclusion before doing a minimal amount of research!

There would be less emphasis on symbolic politics, such as this project, if we could make material progress on social inequity. It does not cost any money to change language. It would be difficult and costly to seriously reinvest in people who have been left behind.

For example, if it was politically possible guarantee schools in poor neighbourhoods were funded just as well as schools in wealthy neighbourhoods, do you people would organize around education equality, or would they organize to change language?

There is a reason why "slippery slope" is a logical fallacy. If Stanford ever proposed to enforce this, then that is an easy off-ramp to the slippery slope.
Hrm I’m not sure this is the hypocrisy HN thinks it is. Musk wanted to stop biased moderation. He’s done so. He wanted what twitter has done previously in terms of biased moderation to be public. He’s done so. He wanted journalists to be under the same rules as other content creators. He’s done so.

Is he obliged to let people promote competitors on Twitter?
I noticed that the estimated cold weather range drop in the article for the Jaguar I-PACE is only 3%, for their definition of "cold weather." I think that's about right. I've been driving one for about 3 years now.

Its rapid charge curve isn't winning any accolades, and its range given the battery size doesn't compare well against most other EVs on the market today. I've got winter tires during the cold season, so that ostensibly drags on efficiency, along with all the other reasons the article lists. The I-PACE comes equipped with a heat pump.

What I will say about the I-PACE is that I find it amazingly consistent when it comes to battery consumption. There's a 150-mile trip with 9,000 feet of elevation gain that I regularly do through the Cascade mountain range year round. The speed limit for much of the trip is 70mph, but in keeping with the flow of traffic I often go a little faster than that.

I never have to worry about running out of charge on that trip. During the summer I'll often arrive with about a quarter of the pack remaining. During the winter, if it's below freezing and there's snow/sleet/ice, I can get down to a little over one-eighth state of charge, depending on how aggressive I am on the throttle. I never experience so-called "range anxiety" and am never surprised by a sudden drop in estimated remaining range.

Furthermore in the 3 years I've owned it, I haven't gotten a reduction in maximum range at all. This is my 4th EV, and I know how lithium ion battery packs degrade over time. The fact that I've gotten no range reduction tells me that Jaguar must have chosen to reserve a significant fraction of the pack capacity as buffer, which might help explain why the range given the pack size is less than other EV manufacturers when the car is new. I wonder what the range of your typical 5-year-old I-PACE is when compared to, say, a typical 5-year-old Audi e-tron.
I moved to Gitlab and stayed there. Principles and all that.
China? Tesla has a huge market over there and Musk doesn't want to anger the CCP perhaps.
So you're saying that low quality low information comments are "sticking it to him and his supporters" as opposed to a more thought out comment regarding the policy or direction?

I know that this is a (very funny) joke, but when I visited Rome I was absolutely astonished that humans could build something so long ago and still stand today. Most people don't have such a visible (obvious), lasting impact on the physical world.

Hah! Can't/won't read because paywall, but I can tell you what it feels like to utterly massacre about 250 linear feet of the residue of 42 years of a thoroughly enjoyed and carefully curated book collection.

We moved across the country and purposely downsized in anticipation of a quite light retirement a few years from now.

The first couple of book boxes to the Goodwill were a quite pleasant experience. Finally, we are in the process of losing significant accrued but debilitating mass!

The last half-dozen were an absolutely gut wrenching emotional desolation. A high proportion of our self-value in life were embedded in those pages, it turns out.

Now however we're over it. As far as we can tell, in our social orbit essentially no-one reads in a methodical way. We were pretty focused on personal enjoyment, which we have always found in the more difficult authors. So, for instance, when three years ago I picked up the 38 yo copy of Ulysses that I bailed on so many years ago, I decided that older me thinks that's the best book I have ever read. My social group though. They apparently considered such an effort (yeah it sure was) to be stupid waste of time ("I would never do that."). Oh well[1].

I kept that one, yep. And my technical collection is down to a nostalgic retention of the two volumes of Hairer et al's "Solving Ordinary Differential Equations". And Knuth. It was very hard to part with Stevens, but I did. We also kept 15 feet of cooking/culinary references. Even with those, my McGee's "On Food..." only lives in my calibre library, but I dislike how awkward it is to look things up.

So, on balance, it was the right thing to do, but it ended up being very, very hard.

[1] I'm not a snob! I have happily read galaxies worth of schlock. If Cosma Shalizi can fess up to it then I will too. But I can barely remember any of them. Joyce, I remember a lot of his stuff, not just Ulysses.

I think private options just cannibalize and parasitize public health services. I see it where I live in the UK and where I'm from in Romania.

In Romania it's just outright graft: public hospital doctors direct patients for cheap procedures to their private clinics and toss anything expensive back into the public system. The government pays for all treatments anyway, but public hospital budgets end up being harmed since 'profitable' treatments are being siphoned to the public sector(and doctors outright steal stuff from the public hospital).

In the UK it's a similar selection bias in what's treated privately leading to adverse selection effects for the public sector. Combined with consultant-cancer draining tons of money in order to figure out how to save money(hint: the money-saving solution is never firing the consultants). Society is getting older faster and the government is trying to cut costs on one of the cheapest healthcare systems in the OECD. Basically sabotage from the top down.

Similar effect happens with charter schools in the US, almost impossible to prevent adverse selection effects leading to increased problem-student concentration in the public schools.
The black and red examples are silly. I’m white so I get that I’ve not had the lived experience but we might as well make the color itself unusable.
I have no evidence but I think that this is some white person’s idea of what is offensive, infantilizing everyone involved. But I guess that in lieu of actual policy that will help people this will do….(that last line is sarcasm)
> mostly because they don’t have dominance in any market.

Keep in mind that at least the FTC generally considers a market to be, roughly, goods and services that are close substitutes for one another[1]. That is, if one good or service can be substituted for another, those may be in the same market. However, as the FTC's summary says, "evidence that customers highly value certain product attributes may limit their willingness to substitute other products." The size and breadth of a network is a product attribute that affects a customer's willingness and ability to substitute any other product.

For anyone else into this topic, "Antitrust and Social Networking" (2012) is a good place to start: https://lawecommons.luc.edu/cgi/viewcontent.cgi?article=1188... (PDF).

Why?

Very interesting, thank you.

To what degree is it decentralized?
Because he's always been an insecure child, who says what he thinks will make him popular or stand out to a group of acolytes. Sometimes that'll work for a while, sometimes it'll really help, but over time you get more cocksure, more convinced of your own greatness and more foolish.

It's the same thing as replacing "homeless" with "experiencing homelessness". It's not saying anything different, but communication efficacy isn't the point.
> In all honesty it's not all that different.

Also lived in both. It's absolutely different, but it depends on the neighborhood. I'd say that SF's average level of horribleness (when I left in 2017) was about the same as the bad parts of Harlem or the Bronx, or the area around Penn Station / PABT. But sure, if you go to the burb/bougie parts of SF, like West Portal, or even Pac Heights, then it's very different from SOMA or Civic Center. Just like SoHo is very different from East Harlem.

But it's gaslighting to pretend that the two are equivalent. New York is unquestionably better, overall (for starters, the police in NYC will typically actually do something when property crimes are being committed in the open air, which is more than I can say for SF.)
Uhhh, I am just now writing a blog post “Blogging in 2023”, and it's a personal reflection on why I blog on my domain instead of using a social network.

And my personal answer is: I blog for myself, and knowing that things will be public forever force myself focusing more.

I write mainly about technical stuff that annoys me, or solution to problems I faced and didn't find a solution on the internet.

Sometimes people write me an email asking for some clarification, and my supposition is that people find my blog 'cause they have the same niche problem.

About following other blogs: RSS or mailing list subscriptions. I use hacker news to find interesting blogs.
You should re-read what you wrote here and edit it.
Also of note is how this policy change was announced during the final match of the world cup.

That's the ultimate version of putting out a press release on Friday.
Just like security can mean "carefree" or "hypervigilant" depending on your POV, obscurity can mean different things.

It can mean trivally or fatuously odd; it can mean hidden; it can mean removal or at a distance; it can mean friction. While these differ for evaluating a security posture, for the outside observer all of these can mean much the same: removal from view, consideration or observation. The outside observer is not preeminently qualified to pass judgement on the nature of obscurity from their "privileged" position no matter how certain they are of their inability to observe.
This sure sounds like a good way to get an antitrust/anticompetitive lawsuit launched against you.
I don't know about that. My estimate would be that QOI is ten times as complex as RLE and ten times less complex than DEFLATE-style compression. It could (barely) share a ballpark with either one.
This is cool, thanks for this! I have added

@media (min-width: 768px) {
body {

because it felt crowded on a desktop screen. I do feel like removing the :visited color difference is a usability negative.

Also the 'add comment' input isn't a button so it doesn't get a normal pointer:

input[type='submit'] {
cursor: pointer;
}

HN's table layout makes it tough to do normal things you'd expect on a site like this.. kinda surprising to see a no-kidding table layout these days. It brings back bad memories. Thanks for posting.

That assertion is nonsense. That would be a weak nuclear interaction, very low cross section.
TikTok is also suspiciously missing.

>client state. A state that is economically, politically and/or militarily dependent on another, more powerful state

I think "client" falls under their colonialism category and should be avoided as well. "Customer" then?

> Mainstream media tends to give in to these threats,

Not sure which parts of the mainstream media you're referring to but certainly not traditional (legacy?) print media like NYT/WaPo.

Maybe just maybe it's not interesting to big outlets because influencers like Paul have less influence overall than is apparent to the subcultures who follow them.

NYT on Paul [1].

> But.. disability is abnormal and negative? How tortured of a definition of 'normal' must one use to make blindness normal? And I suspect if the author of that sentence were offered, say, $100,000 to undergo a painless but irreversible blinding surgery, they would very quickly admit blindness is a negative

As you can verify with some Googling, there are many Deaf people who choose not to undergo surgery to gain the ability to hear. (This isn't a universal preference by any means, but it's also not fringe.)
>red team

Baffled by this inclusion, never in my life have I made that association. I'm also hugely against sports teams naming themselves after Native American stereotypes, but here it's literally just a color.

>Karen

Totally agree with your points, in what world is white okay to use there when they're arguing against "blackbox". Also, Karen has a lot more connotations beyond just race, there's a class/aspirational class connotation. There's a reason it's not "Madelynn". Not saying it's okay, but it's part of a trend in this list of not understanding connotation and context, and a general lack of thought in their alternatives.
For a while? I've only heard of that in the past few days.
Interesting mind-centric game. Up until the penalties, where the Argentinian goal keeper managed to get ahead psychologically it seems.

> Prohibited platforms:

> Facebook, Instagram, Mastodon, Truth Social, Tribel, Post and Nostr

> 3rd-party social media link aggregators such as linktr.ee, lnk.bio

Missing from this list are things that are not direct competitors, but where creators have monetized brands that they're motivated to promote on Twitter, including: YouTube, OnlyFans.

I suspect that promoting blog articles on Medium and Substack is still OK.

I also see TikTok getting incidentally promoted on other sites (even if it's by stealing content originally from TikTok, or referring to TikTok fads).

No mention of Reddit, which could be very similar to Twitter (but better), but historically has de-emphasized user profiles/identities.

Is Twitter focusing on competitors that permit user-profile-centric sharing sites?

(BTW, nice of them to give everyone a list of competitors they feel threatened by.)
> Wow, greatest ever final!

Meh, a penalty series spoils the nature of the game.
I'm not being hyperbolic when I say I believe the explanation is that Musk is a fascist. Fascism is notoriously difficult to define, but what I mean here is that Musk ultimately believes only in the will to power; all stated principles will ultimately be abandoned at the time when they conflict with his will to gain & maintain power. You can compare this to Trump; Trump excoriated Clinton over her handling of classified information wrt her email server, but not only did many Trump administration officials (including his children) make similar mistakes, but we've seen with the document scandal that he had no regard for classified information when it suited him to keep them in an unlocked closet space. (This is not to defend Clinton; I have no interest in doing so.)

So Musk talked about being a free speech absolutist, until such a time as he felt threatened by it. The only thing Musk actually believes is that he is the most deserving person to wield power, and because he the most deserving, anything he does in support of that is justified. He can justify it by saying, I'm making humanity an interplanetary species, and in doing so I will save billions of lives.

(He won't make us an interplanetary species, his plans for colonizing Mars are gibberish, nothing he does is truly justified.)
Wow, when I saw this list, I thought it's a parody post. Then I went away and read the suggestions...
Inventing Reality Documentary from Matt O'Dowd of Space Time
Musk is being revealed as an emperor with no clothes. He was originally lauded because he had great ideas, put his money where his mouth was, and delivered some great products. And yeah, his companies needed to be a grind to succeed where so many have failed (Tesla being the only American car startup to succeed in something like 100 years). But going into a respected tech company like Twitter and gutting 80% of the workforce, acting like you know better than the engineers who built the thing, and rolling out and back policies and features without any real plan or thought, is showing that Elon believes he can just rinse and repeat his grindcore/dictatorial culture on any company and it will be successful. Something like Twitter with hundreds of millions of users and most of them non-paying, with governments and big brands depending on it, that runs a lot of the public discourse, can’t withstand this bull in a china shop management mentality. We all are seeing this unfold and these posts are shorthand ways of calling this out. It doesn’t need to be said in such great detail. The upvotes are an acknowledgement from the rest of us that we see it too.
