You jump from bizarre accusation to bizarre accusation.

Here's my go at diagnosing you (and this goes for many people in this thread): the centerpeice of your worldview has been "liberals good, conservatives bad" for your entire life. Now, when faced with clear evidence of well-meaning liberals enacting harmful policies in the name of "racial justice," your brain short-circuits and you start sputtering gibberish (or arguing semantics, e.g."you can't define wokeness!").

The way out is to admit that liberals are human, they make mistakes, and "wokeness" and its associated policies are examples of this. Don't worry, after you start seeing reality more clearly, you can still vote for the Democrats! They're still better than Trump!

yes really relevant/related, as that talk also mentions that a sub-1 Hz variation of the nominal 50 Hz is already enough to cause blackouts - which is also the case for the current blackout: https://x.com/Nexuist/status/191687508022891747

the talk discusses further aspects of the European energy grid which are relevant for the current situation.

"Unfortunately there simply isn't enough demand between SF and LA alone to justify the insanely long stretches of a direct rail project."

I will stipulate that that is correct at this very moment.

However, it is my contention that a truly high speed rail link (sub two hour) between SF and LA would have manufactured demand as an entirely new set of trips, activities and lifestyles would have been enabled by the ability to step on a train in LA and step off at the salesforce tower 1:55 later ...

Doesn’t seem that unlikely to me. Ollama on Mac can already run decent DeepSeek/Llama distillations. For a lot of tasks it’s already good enough.

And 2029 is in 4 years. Four years ago leetcode benchmarks still meant something and OpenAI was telling us GPT3 was too dangerous to release.

I use something like this, indirectly.

HedgeDoc [1] (a markdown collaborative pad tool) also uses reveal.js to build presentation slides from markdown pads. It's quite easy to use and works very well. Also it supports LaTeX for math and code highlighting.

The presentation mode is able to manage a dual screen interface so the speaker can have a timer, see the next slide, and some private notes if necessary.

Very cool!

CA HSR actually is "high speed."

The distance from LA to SF is about 665 km (following the planned HSR route). A travel time of 2:40 means the train has an average (not top) speed of 250 km/h, which is very competitive internationally. Even if we use the shorter I-5 route as the baseline, the average speed is still 230 km/h.

That's competitive with the fastest French TGV lines, and much faster than most European HSR lines. For reference, the fastest lines in the world run at an average speed of about 290 km/h (e.g., Beijing - Shanghai).

Calling this a "slow, circuitous route" is really not accurate at all. If CA HSR gets built as originally planned, it will be one of the faster systems in the world, and nearly as good as the best systems in Europe.

I hate to say it, but I'm really okay either way as I think about it more.

I'd prefer to stay aligned with politicians who don't "go low", but I can also see the benefit of forcing our far-Right extremist party have to occasionally eat some of what they shovel out every day. The mere hint of consequences for the decades of bad faith from the Republican party makes them squeal that they're being oppressed. If they're going to complain about unfair treatment constantly, is it so wrong to make them actually endure some?

I'm a little ashamed, but all of my sympathy for Musk and MAGA has been spent. There are people who are actively being harmed by this administration that are far more worthy of our concern.

What purpose would be served by freaking out? Would freaking out somehow help me to avoid death? Or at least prolong my life? Freaking out in fact shortens my (useful) life because now I've wasted time in some state of agitation that could have been better spent doing virtually anything else.

Hoping I get to see my grandkids. Hell, even see them start to marry off, come to that. But I'll spend what time I've got trying to enjoy the things that are here, now. You should do the same.

I guess technically I havent seen trump nor musk say this. It was the FBI who labelled it such.

Domestic terrorism to me is ideologically or in this case politically motivated violence with an intent to influence or coerce the victims into changing something they dont want to change.

That's totally what's happening here.

It can be, depending on the nature of the software. However, for a heaping ton of software (such as libraries or software that is meant to be used without internet access) it can be the worst option.

The real answer, as always, is that there is no universal one-size-fits-all solution to this.

Great question!

You're right that it can definitely be faster — there's real room for optimization.

When I have time, I may write a blog post that will explain where the cycles go, why it's different from raw assembler toggling, and how it could be improved.

Also, just to keep things in perspective — don't forget to compare apples to apples: On a Pyboard running MicroPython, a simple GPIO roundtrip takes about 14 microseconds. PyXL is already achieving 480 nanoseconds, so it’s a very different baseline.

Thanks for raising it — it's a very good point.

Do you think you needed to have those times to play around in the engine? Can a beginner possibly even know what to plan for if they don't fully understand the game engine itself? I am older so I know the benefits of planning, but I sometimes find that I need to persuade myself to plan a little less, just to get myself more in tune with the idioms and behaviors of the tool I am working in.

Using poor quality AI suggestions as a reason not to use Rust is a super weird argument. Something is very wrong with such idea. What's going to be next, avoiding everything where AI performs poorly?

Scripting being flexible is a proper idea, but that's not an argument against Rust either. Rather it's an argument for more separation between scripting machinery and the core engine.

For example Godot allows using Rust for game logic if you don't want to use GDScript, and it's not really messing up the design of their core engine. It's just more work to allow such flexibility of course.

The rest of the arguments are more in the familiarity / learning curve group, so nothing new in that sense (Rust is not the easiest language).

> Unfortunately, it is a failing of many projects in the Rust sphere that they spend quite a lot longer in 0.x than other projects

Yes. Because it makes a promise about backwards compatibility.

> Rust language and library features themselves often spend years in nightly before making it to a release build.

So did Java's. And I Rust probably has a fraction of its budget.

In defense of long nightly feature more than once, stabilizing some feature like negative impl and never types early would have caused huge backwards breaking changes.

> You can also always go from 1.0 to 2.0 if you want to make breaking changes.

Yeah, just like Python!

And split the community and double your maintenance burden. Or just pretend 2.0 is 1.1 and have the downstream enjoy the pain of migration.

The way Dutch people combat the admittedly scary process of dying is by treating it as an event. I think the best comparison is a wedding. You do your rehearsals, pick out music and clothes, train the bridesmaids, pick a venue, call the catering. And then ofcourse you have the administrative stuff to take care off- banking, house, taxes. Time flies until the big day happens.

While the post has good points - you can't talk about this subject without defining what price points you're selling at.

A company will have radically different sales motions if they are selling a good/service costing:

* < $5k * $5-50k * $50-500k * $500k +

Seems to me this post is probably targeting the top 1 (or 2) bullets/segments.

The key is, you gotta be pretty cold in the analysis. It's probably more important to avoid what you hate than to lean in too hard to what you love, unless your terminal goal is to work in $FAVE_LANG. Too many people claim they want to make a game, but their actions show that their terminal goal was actually to work in their favorite language. I don't care if your goal is just to work in your favorite language, I just think you need to be brutally honest with yourself on that front.

Probably the best thing in your case is, look at the top three engines you could consider, spend maybe four hours gather what look like pros and cons, then just pick one and go. Don't overestimate your attachment to your first choice. You'll learn more just in finishing a tutorial for any of them then you can possibly learn with analysis in advance.

This would only be true if Elon did not own any TSLA stock.

> Moreover, if you're looking at politics. Republicans dont own teslas... it was democrats who pushed electric cars and tended to buy teslas. So it's democrats destroying other democrat's cars.

From https://x.com/i/grok/share/vqgQXxcDQZN99MYy69UYCZKxz

"However, by late 2023 (the start of the 2024 model year), that shifted dramatically—only 15% of Tesla buyers were Democrats, while Republicans rose slightly to 32%, and Independents jumped to 44%."

> This is the classic dead-end startup story from beginning to end. It checks all the boxes:

Oh my... I concur. I've been in the very exact same stupid play about 10 years ago. 3 cofounders, not one to understand tech, 1 hired me as a consultant, then invited me with a few shares and a salaried CTO role to build the solution, and it's been the exact same scenario.

Do not, ever, associate (figuratively or contractually) yourself with people you wouldn't go hiking with in the wild for one full week, and coming back from it craving for the next time.

Even if you can't stand being in the same car for one hour, don't work with them at all.

Before I had a dash cam, I had somebody at a stop sign just throw it in reverse and back right into me. I thought I was completely fucked, that they were going to say that I rear-ended them and I would have no recourse.

Luckily for me, they just gassed it and took off. They lost me at a roundabout when I had to wait for a box truck to go by in the night.

I now have a dash cam. No amount of defensive driving would have saved me if they were fraudsters.
by Centigonal | 2025-04-28 19:57:21+00:00
yes, and maybe? I think it's important to hold the tension that you are doing something that is both good and harmful (like both building a really nice chat app you give away for free and using the network effects of that app to collect everyone's data and influence them, or protecting people from fraud but also improving the bottom line of Wall Street banks that are contributing to the increasing financialization of everything).

I think acknowledging incentive structures is alright, but ending the process there and not leaning into understanding and manipulating them is the real issue.

This is fantastic news. The memes about "Temu Quality" are all too true - Temu exploited a loophole in US-China trade and shipped huge volumes of awful quality products that quickly ended up in landfills. The prices in Temu weren't realistic and certainly didn't reflect the environmental cost of producing, shipping, and disposing of goods.

Too many fantasy tales of overnight successes out there. It takes an enormous amount of work to make things look easy - in a commercial setting. Some people just pick things up and are relatively good at them but they cannot productive it. To do so you have to be able explain it and they don’t understand it, they just do it. So they can’t make a business out of it and they cannot become top of their field because they lack the fundamentals and the work ethic.

I could talk anybody to death with all of my ideas. I only get to work on very few of them. I can’t imagine how sad a life it would be to only have one. It’s great for mentoring though because there’s always something shiny on the shelf and I can let them window shop for one they like.

> I don’t fear death, it is natural. I fear the suffering society will put me through when I’m old and ill, because they can’t cope with death.

Assisted death--one with dignity--is rare recent development about which I'm genuinely and wholeheartedly happy.

What unsettles me--as rational as I think I'm--is the thought of being born again (duh!). I lead a very comfortable life, but far from "perfect". I can say I'm content. What are the odds that I'll be content in my next life? How likely is it that I'll be born in the right country, to good parents, follow the right religion, and have a brain wired in the right way to make a decent living? I'm not hopeful. So, I've "decided" that I want to be a rock in all my next lives. No emotions, no feelings, no struggle, no pain, no indignation. Just a fricking rock.
by fedeb95 | 2025-04-28 19:58:15+00:00
I get your point and I agree to a certain extent. However, it's arguable that everyone shares the same aim, that is, to understand reality. Some want to go down a road, no matter how it got built, or, some think, or better don't think, no matter where it leads. In that world, an artificial entity that can 1) create an aim and 2) build enough understanding to execute and 3) execute could be valuable. Right now we're at the 3) in the specific context of byte arrays. Now, an artificial system that could also understand, i.e. possess some kind of structure of concepts, and from there also produce the "need" to create something, that would be a huge leap forward. Forward toward what? I don't know.

As someone building a new hosting provider with a free tier (https://val.town) it's so lovely to see folks like Simon value long-term stability. It makes it easier to make the business case to invest in it. At the end of the day, it's all about trust.

I don't really have a huge problem with the route. Branch lines to individual towns don't really make sense - you lay even more track, need more trains, complicate operations, and the value proposition for potential customers in those towns drops substantially vs a one seat ride to any destination.

Honestly given the once in a lifetime scale of the project, too, if they run a train from LA to SF by 2050 it even 2060 I'll actually be quite happy. There's no reason it couldn't keep operating for a hundred years after that. I mean I'm skeptical of that happening as well lol I'm just saying, projects like these will serve many generations and will only get more expensive in the future, so i support biting the bullet on doing them now despite our inefficient, backwards way of doing them.

> Most profoundly autistic people don’t go the bathroom unassisted, or pay their own taxes. That’s true.

As long as you define "ability to go to bathroom and pay taxes" as profound autism, that's true. But as I said, autism is a spectrum -- there is no such thing as "profoundly autistic". That's not a thing. You're again trying to make a dichotomy, and this is a misconception both you and Kennedy share.

> Wild conspiracy theories help nobody, and also harm autistic people.

We are at the point where it's no longer wild. They are literally planning a database, and planning "wellness farms", and using dehumanizing language to talk about the worth of autistic people within society. I'm really glad that for you, these concerns autistic people have about these plans are esoteric and "wild", but for the people they are targeting with registries and camps, we cannot afford to be so flippant.

No one else is going to advocate or look out for autistic people, so we have to do it ourselves, and if that means people think we are overreacting so be it. We're used to being told that anyway.

Any advice for leveraging a startup role to boost your career? I’ve seen friends turn their positions at early stage companies (Pre-Seed/Seed/Series A) into things like raising funding for their own ventures, hosting galas at SF museums, putting on international fashion shows with their alma mater, or even speaking gigs. And honestly, I have no idea how they pulled it off.

My 85yo dad just spent 3 weeks in a nursing home because he had a digestive issue that weakened him. The stay made his mental and physical health very much worse. He didn't get enough sleep in there (lots of noise all night) and the food was abysmal - he already had problems with sarcopenia and they weren't feeding him nearly enough protein. I'd call him up or visit and he seemed to be having trouble separating his dreams from reality - he was hallucinating which isn't something that was happening before. At the 21 day point they released him (due to medicare limits) and I took him home to his house and stayed with him for 2 weeks making sure he had good food, good sleep and some sun every day. By the end of those 2 weeks he was remarkably better and I was able to leave him on his own. Nursing facilities are necessary for some, but for many they're making their problems much worse.

It's a similar distance to Paris to Marseille, a 3 hour journey. Price for that seems to vary between 29 and 80 EUR depending on time of day.

That's "get on the train, get off the train three hours later", so in practice is much faster than a 90 minute flight, which is "get to airport, go through security, walk seemingly endlessly to gate, fly, walk seemingly endlessly through baggage claim etc etc, get out of airport". The train is, of course, also _far_ more comfortable than a plane. Personally, I'd opt for the train...

I suspect if the damn thing ever gets built, flying between SF and LA will more or less become a thing of the past. Like, why would you?

If you look at it by map there's not much more interstate highway than railway.

Interstate highway is also far cheaper to build and maintain than you would imagine. It took around $114 billion to build interstate across the entire country, while the high speed rail project in just California is already upwards of $128 billion.

On Europe that is kind of exactly my point, high speed rail in Europe is built and maintained by federal governments with high levels of participation, interest and oversight from their population. This can never happen in the US because our federal government has to oversee a very wide amount of area and states are not so autonomous and self-governed that their populations primarily interest themselves with their state governments.

That's 90 minutes in the air, not total trip time.

The HSR is 160 minutes from downtown to downtown. There's no check-in, no security check, no arriving 1-2 hours early, no travel to and from the airport. When you count all of that, HSR will be faster than flying. It's also far, far more comfortable - there's no comparison there.

> Huh? I was giving an example of how we make undecidable properties trivial in languages. It can be any property.

Yes, but insisting you have to be 100% machine verified, while the program is correct, it is impractical. While it might be Turing complete, it can't express equivalent behavior to a C program.

This is one of those quotes like "Don't let perfect be the enemy of good".

Look at your definition of memory safety, by it nothing other than ATS or some Lisp derivative running on a Lisp machine is actually memory safe.

Sure, it's theoretically sound, but it's not pragmatical.

> We have empirical evidence that real seatbelts increase safety; things are nowhere near as clear for language soundness.

We have empirical evidence that Rust has measurable impact on bugs, especially memory safety ones.

Brightline West will probably have more success primarily because the private property issues will be largely avoided.

> The project aims to transform transportation in the region with fully electric trains capable of reaching speeds up to 186 miles per hour, enabling the 218-mile trip between Rancho Cucamonga, California and the Las Vegas, Nevada to be completed in approximately two hours. Brightline has secured all key rights-of-way necessary to construct the railroad under long-term agreements, including leases, licenses and easements, with the states of Nevada and California and the federal government for passenger rail access to the existing I-15 corridor.
