Forking and this package can be useful if you know that the unsafe code is really unsafe and have no hope of making it better.

But I wouldn't use this often. I'd be willing to bet that you'd lose all performance benefits of using Rust versus something like Python or Ruby that uses forking extensively for parallelism.


> have no hope of doing better

Yeah, this is really the main use case. Its a relatively simple solution when you can't do any better.

I think that's particularly helpful when you're invoking code you don't control, like calling into a some arbitrary C library.


It's really surprising to see that in HN.

I personally fucking love rockets and what he did. But for the past years made me hate the man.

My guess is that most people here are center-right wing, or at least a majority of HN isn't left-leaning.

It's surprising he managed to make even that audience hate him


To be clear, I think it's fine to be excited about what SpaceX does. Elon is not the one thinking, designing, building and flying the rockets.


HN is extremely (American) left-leaning. Do you not remember the threads about the murderer of the health insurance CEO? Any thread about US politics? Or just the simple fact every thread about office politics or workplace relations is VERY pro-unionisation, VERY anti-manager. HN highly favours higher taxes, higher minimum wage, trade unionism, work from home, open borders, net zero etc. Of course it is an American leftism rather than European leftism or Commonwealth leftism which have different focuses.


Working from home isn't leftwing, nor anti-manager, nor is netzero and nor are a lot of your other issues.

That you think they are is the propaganda working on you.

I can believe in the profit motive without thinking that we should ignore science.


They're probably in the minority here like they are in real life, but there's plenty of right wing extremists, just scroll through any politics trump/musk thread in the past few weeks and about Israel for the past year.

Even the current administrations project 2025 comes from right wing tech extremists (mixed with christian faschists) that believe that tech CEOs should be feudal kings in a broken up America, I don't think any website is closer to this than hackernews.


Honestly, until very recently, I haven't felt that at all. Just look at the thread on Trump winning the elections. You might be right in that the majority of users may be democrats, but that doesn't mean they are all pro-union, pro-redistribution, etc.

I wouldn't call management-bashing leftist, everyone engages in that, even if right-wingers refuse to go further than individual action.


Ioniq is so fucking amazing. It's also always the top EV seller ex. Tesla.

It's the best parts of Tesla mixed with the best qualities of Korean manufacturing.

Volkswagen's ID5s are also very good since last year. Many of the software woes seems to be fixed.


Drove an ID5 on a trip in France last year, really good car.


Remember that... we don't have numbers yet from Tesla in Europe after Musk did the Sieg Heil.

I live in Europe and people absolutely went batshit crazy about it, not only in Germany. People really despise that gesture.

I'm willing to bet sales in Europe for Tesla FY2025 will be terrible.

I know many Tesla owners here that are considering selling the car because they are also afraid of the car dropping even further in price because too many people will want to sell it.


I'm in the Netherlands and the used market for Tesla has already dropped like a rock. It is flooded with cars from leasing companies who after 5 years now want to sell them on for deprecation and tax purposes.


Yup, you can pick up Teslas cheap in the UK now ... and I still won't buy those PoS's ...


This is comforting, as an Argentinian living in Germany. 1 out of 5 people here voted for the AFD...


On average, yes. But if you look on a voting map[0], you'll notice that the majority of those votes comes out of the former DDR. In many other areas, much less than 1 in 5 voted for the brownshirts.

[0]: https://www.tagesschau.de/inland/bundestagswahl/wahlkreiserg...


If you look even deeper, at people's actual attitudes[1], you'll see that far-right positions are approx. equally distributed in Eastern and Western Germany - the kind of people voting AfD in Eastern Germany (currently) just vote CDU in Western Germany.

[1] = Leipziger Autoritarismus-Studie, https://www.boell.de/de/leipziger-autoritarismus-studie


Yes. But: The map does not reflect polulation density. (Which is rather low)


DDR is not a proper Germany, cant count them


No, the point I am making is that it very much depends on their location if this "1 in 5"-average is even remotely true. And looking at overall population statistics and concentration of jobs, it's comparatively likely that somebody migrating to germany is _not_ in those areas.

And I do think that's important to point out.


But immigrants do not vote unless they become citizens, do they?


I was originally replying to this comment:

>> This is comforting, as an Argentinian living in Germany. 1 out of 5 people here voted for the AFD...

My fundamental aim here was to show the poster, that it's likely not as bad where they are - and since they are a migrant, I assumed that they were likely not in those really bad areas. Intended as a positive message. Sadly, I apparently butchered the delivery of this message, as several people interpreted it completely differently.


What about Germans living in Argentina? :)


What about operation paperclip?


Lmao


And 4 out of 5 didn’t.


Thank you, I know how to count. Previous election AFD had half the votes, so what is this "4/5 glass full" comment about?


You have 4 years to address the issue, but instead chose resignation. Rather than collaborating with the other three to help guide the fifth away from radical positions. Now is probably the easiest time to do something against it before it's 2 out of 5 or even worse. What did YOU do in the last 4 years?


paid my taxes and chose public health instead of private so oma und opa could get medical attention they deserve. And now planning on moving to Ireland.

I cannot address the issue because between family and work and interviewing, time is out. I don't speak German, I can't vote.

I'd like to understand if your comment is coming from a German or not.


You've done only the bare legal minimums required to stay in the country. As a non-resident, you would also face challenges obtaining private insurance that provides the same level of care as state insurance for the same price. When fighting fascism, that effort is insufficient. I hope you find time to take up the fight when you're in Ireland, before there are no countries left to escape to. Good riddance.


> Good riddance.

.... ok?

edit:

> guide the fifth away from radical position

naive.


What to do you expect? You are crying about the society in a country you are residing in while not integrating into said society (at least learning the language) nor trying to mend it in any other way. Your first reaction is to leave it behind like you did with your own home country. I would take a sharp look at myself and my convictions before complaining about others if I were you.


You know what? You remind me of a middle aged woman who approached me screaming in January 2021 in a station in the U7 in Berlin.

I was lost, looking at a map when a woman approached me. I first thought she was looking to help me, but she came screaming in German WHAT ARE YOU DOING WITH THAT FACE MASK, THIS IS GERMANY, YOU HAVE TO FOLLOW THE LAW OR GET OUT OF MY COUNTRY.

The facemask I was using was a special face mask developed in Argentina: https://www.conicet.gov.ar/scientists-developed-anti-viral-f...

Of course the woman did not have any idea about that. But instead of asking nicely, she started screaming at me.

You remind me of her alright!

edit: also, giving opinions about my person when you don't know how or why I emigrated from the country I was born and lived for 30 years is in bad taste and reeks of Euro privilege. check YOUR privilege.


The technology of the linked facemasks was novel at the time but they were never certified as medical masks (I used them myself before medical masks were mandatory.), neither in Argentina nor in the EU while also looking like simple cloth masks. At the time she was right to say that you were not following the law. She was not right to say that you should leave the country but I bet you are also not telling us the whole interaction of your anecdote.

Based solely on our discussion, there appears to be a strong sense of entitlement in your positions and a reluctance to acknowledge your own failings while quick to point out procedural errors by others.


> Based solely on our discussion, there appears to be a strong sense of entitlement in your positions and a reluctance to acknowledge your own failings while quick to point out procedural errors by others.

> reluctance to acknowledge your own failings

> I bet you are also not telling us the whole interaction of your anecdote

oh well...

The interaction was exactly that. She only said the words I quoted and left, while I stayed petrified after my first xenophobic encounter in Germany. Only when she was far away I reacted and yelled at her an argentinian insult that has no translation, out of frustration and fear. So typical for a lot of Germans and Argentinians to fake being demented when you tell them there is a racism or xenophobic problem. "surely you misremember", "surely that was not all the dialogue", "I never have seen a racist in my whole life" (ok that last one actually is hyperbolic).

Of course the mask itself was not FFP2 in an official manner, that is a fact today and at that time. That lady had no idea and should have explained to me how important it is for people in Germany to follow the law, no matter what. Instead, she reacted like that. Of course I was in the wrong, and quickly procured myself an FFP2 mask as soon as I could.

You know why I'm leaving Germany?

Because I could not adapt to the culture. I could not learn the language.

Why Ireland? Because I have family there, because I speak their language, because people don't stare at me 24/7 on public transport, because the border police are not mini-dictators that when educated about their own laws scream at you WELCOME TO GERMANY while angrily smashing your Argentinian passport into the small table at the booth. (Now that I am a Polish citizen, I can avoid interacting with those mini dictators. Isn't that what I am supossed to do? Not stay in a country I could not adapt to? I gave it a few years, but family members dying 1000's of kilometers away from you take a toll.

What is YOUR problem, dude? Any more comments on how should I live my life?

Stop being like that, please... Engage in some empathy. Put yourself in someone else's shoes for once.


This seems to be your first sincere comment in this thread, and I'll leave it at that for everyone else to see.

> Any more comments on how should I live my life?

I would also suggest you stop demanding empathy when you demonstrate none yourself. Regarding your anecdote - do you know if that woman was clear minded? Do you know if she hadn't lost a family member to COVID the day before? This highlights the fundamental problem with anecdotal evidence: we can talk in circles, and none of it establishes a meaningful point.

> Stop being like that, please... Engage in some empathy. Put yourself in someone else's shoes for once.

You're right about one thing: I struggle to show empathy for someone who complains about racism while exhibiting racist behavior themselves.


Around 50% of the population has an IQ of less than 100.


This just inspired my curiosity, How well normalized is IQ, is it persistent over time, or does the curve meander.


In France, Tesla Model Y is -57% (compared to Jan '24) at 640 units in January, while other brands are growing at 2813 (Renault 5), 1548 (Citroen E C3), 1177 (Renault Scenic), 762 (Peugeot 3008), among others.

I know some who are considering selling the car because they are afraid of what other people will think knowing they drive a Tesla.


I would encourage you to watch the whole video of the incident, with sound, and then put your hand on your heart and honestly say you think that was a sieg heil. (but don't throw it to the crowd after)


It was not a coincidence that it looked like one. Nobody with knowledge of contemporary history would make a gesture that could be interpreted as "Sieg Heil" by mistake at an event that is watched worldwide.

Why do people keep saying that Elon is on ketamine? What news did I miss? Did he check himself in a rehab? Did he do something outrageous a a party? I am curious. Thanks!



https://www.wired.com/story/ketamine-psychedelic-slumber-par...

> “Ketamine is helpful for getting one out of the negative frame of mind,” Elon Musk told an interviewer last year. The unelected man currently gutting US federal programs isn’t the only one who thinks so. Ketamine, approved decades ago as a surgical anesthetic and long used as a party drug, is the off-label mental-health treatment of the moment. It induces a “trancelike” state of “sensory isolation,” researchers say, and may temporarily boost the brain’s neuroplasticity—which, in theory, makes mental ruts easier to escape. At the same time, ketamine abuse can be deadly, and the drug remains illegal to use without a prescription. (Musk says he has one from “an actual, real doctor.”)

Basically costs $350 to get a prescription.


He talked about using Ketamine. Openly.


I've watched it, many people have, and have still firmly concluded it was a purposeful action. It's debatable whether it was a true "I'm a Nazi" move or a "I'm a troll" move but the smirk on the face, the long, long history of trolling and antagonizing opponents, the previous comments from Musk that the left was calling him a Nazi, etc... all indicate that he intentionally did something provoking.

This is even more true for the latest copycats from CPAC, which show that the Fascist salute is being normalised and becoming a MAGA symbol. Think about that. Whatever Elon's original intent, the American right is now knowingly doing the fascist salute, not as satire but as a open sign of their politics and provocation to their opponents.



I watched the video with sound quite a few times. It was totally heil hitler salute. (Not to bring up the statement Elon made about how Germans should stop apologizing for holocaust. At that point even the anti-defamation league gave upon him. Elon is fascist to the core)


I don't understand why modern day Germans would have to apologise for the holocaust either, maybe I'm out of touch.

I also don't know why HN keeps these Elon posts up because they're always a shit-show of reddit-ness and I believe most other similarly high-conflict subjects would have been nixed by now.


I would encourage anyone who thinks it was not a Nazi sieg heil to go into work and do the exact gesture in front of your boss, and then report back here on what happens.


Actually, I think they went "batshit sane", what other reaction could a sane person have after seeing that happening on live TV, during the POTUS investiture?


You have no control over that. If you are thrown into a bad project, you will rot with them. Or turn the situation around by using your own expertise.

That's what being a leader means, you deal with the ambiguity, is paid more, but if things don't go as expected, you are axed.

The only thing that can save you is if you have built relationships with senior directors that could save you.

Just a reminder that Tomorrow the CEO can wake up and desire to cut people to increase their margins and Staff engineers working on improvements are the first to go.

There's no such thing as a career. Just focus on making money while you can.

Also, make sure you have a few doors open in case you need to get out.

This means you want to have a flexible skill set in case you need a new job, also a network of people that wants to work with you.


It doesn't matter.

US companies will want to have consumers and Europe has them, so they would like to offer their services in the EU.

AI hardware is also produced in China. Americans don't want to talk about it, but Huawei has good inference hardware and software.


    US companies will want to have consumers
Consumers who can pay. If Europe falls behind and does not have the capability to produce goods or services that are in demand in the US and China, the European consumers might want those US/China products and services, but they can't pay them.

Look at the German automotive industry. Once they produced something the world wanted. Will they still do that in the age of electric autonomy?

Except for ASML's technology, which competitive advantage does the European industry have to stay relevant in international trade?


Just do Andrew NG's course.

It will show you the maths, you'll build simple neural nets (from maths!) that can read digits and scale it from there.

While doing it, you may struggle with some of the maths, just take a deep breath and invest sometime to fill the gaps you need and continue.

Learn about CNNs and everything else step-by-step. It's awesome.


Andrew Ng's course is great for the learning NN's from scratch, but not understanding how NN's fit in the broader discipline of AI.


None of those,

First, you build something that fixes a customer problem that they are willing to pay for.

Whether it uses AI or not, the customer doesn't care.

The only thing that matters is the value you add and your ability to sell and showcase how your solution is better and attract customers.


Leetcode and coding competition problems were never once thought to be a good representation of our ability or skill in the Software Engineering area.

It just became really important in the last decade or so with Big Tech using them to filter candidates as a proxy for intelligence and dedication.

It makes sense for Big Tech to use it because they are huge companies, and often enough their engineering talent will work in very specific projects, rarely building features using a popular framework or OSS tools.

90%+ of the companies still don't use that method because they hire people that can use popular OSS tools to build software for them.

So they look instead to judge your experience in a certain framework, language or infrastructure piece.

So overall, I believe nothing has changed.

Mathematicians will still need to learn to solve integrals and remember rules without a calculator to pass their tests.

Coders that want to join Big Tech will still often have to do leetcode challenges without AI until they find a better way to filter for intelligence and drive.


I believe you should pay for a cursor license and learn how to use it.

You'll quickly notice how limited AI is.

It can generate some code, but often it's just boilerplate similar to what Frameworks and Libraries do.

It is far from fixing tough bugs, fixing performance or architectural issues.

Focus on what you think the AI isn't good at doing.

We don't write software, we value add to business
