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.

I feel somewhat vindicated seeing no pro-Elon comments here anymore (or very few). I've been saying since 2017 that he's crooked and full of sh*t, when he engaged in union-busting while describing himself as a "socialist". Now that he's overtly showing his incompetency, stupidity and rancid ideas to the world, people see him for what he always was. A failed father abandoning his children, a pathetic man cheating at video games to seek attention, a mediocre self-serving neonazi.

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

What are you going to get instead? I think that Chinese EVs are flooding the market but it's absolutely not better to support China than supporting Tesla. Hyundai/Kia - maybe an option, primarily because people don't know that much about South Korea :)

I find it very sad that purchasing a car from a publicly traded company with tens of thousands of employees is somehow interpreted as supporting the politics of the CEO of said company. Life shouldn't be politicised that much

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.

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.

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.

null_investor commented on Ask HN: Could Europe build their own AI infrastructure? · Posted by u/ArtTimeInvestor

null_investor · 7 months ago

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.

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.

null_investor commented on Ask HN: Currently, is it better to work on AI shovels or AI applications? · Posted by u/iusewindows

null_investor · 7 months ago

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
