My point is that the less decent but more aggressive ideas will dominate when their organisers and the masses use screens around you. The half-trillionaires will ultimately continue to dictate terms of your broader community, environment and atmosphere.

Ideas don't grow because they're good but because they push instinctive buttons, or save money, or give people what they want with minimal effort.

It goes without saying that anyone can opt out and ignore anyone beyond their personal circle.

I think there's another option, which is using screens in a more positive way.

Thinking about wild scenarios is fun and sometimes even prudent.

But acting on it at this point is tragic premature optimization. Musk isn't a stupid person so I have to think in his heart he knows his story is more about PR and being seen as a visionary as something that will actually be done in the next thousand or ten thousand years. Even if there is some climate catastrophe that causes 99% of the population to die out and any civilization to collapse, the remaining 1% are better off on Earth than trying to spend their limited manpower to get to Mars, even if some crazy trillionaire has established a beachhead there.

As an analogy, it feels like some person living paycheck to paycheck and having only $20 to spare at the end of each pay period and saving up that money ... not to invest it in some way that improves their lot, but to hire a tax attorney to help them plan how to shelter $1B in income in case they win the lottery.

It's pretty much only Americans who think clothes on clothes lines makes a place look "poor".

Consumerism demands that everyone buys a tumble dryer, therefore not having a tumble dryer means you're a povvo!

Meanwhile, in civilisation, I have a washer, a dryer, and a collapsible wall-mounted clothesline in my apartment, and I can choose which piece of clothing goes where to dry depending on need!

That depends on what “centralized” means (i.e. whether we're conflating “decentralized” with “federated”, as is usually the case when talking about systems like ATproto, ActivityPub, Nostr, etc.).

In any case, AFAICT it's possible to self-host every part of the ATproto stack, and people have indeed done that. Third-party PDSes, relays, and applications/clients can talk to one another and with the ones Bluesky PBC operates. That satisfies the meaning of “decentralized” as most people use it (at least as well as other federated protocols like ActivityPub and email satisfy it).

Are you pretending to know? This is an entire field of study, Paleolithic cave art references and phosphene phenomena, there's hundreds of papers about this. We can verify the scales on cave walls and the distance to optic, literally where someone could stand to reexperience the entoptic.

Cool projects!

A few suggestions:

- You're committing .zig-cache to git, but that's build output, so it shouldn't be under version control. You should add it to .gitignore (you already have zig-cache without leading dot).

- Your README.md refers to a CONTRIBUTING.md that doesn't exist

- It's helpful to say exactly which Zig compiler you need. It currently says "0.10.0 or later" but 0.10.0 is almost three years old now.[0] Most 0.10.0 code does not compile in 0.15.1.

I'm not trying to be gatekeepy or anything, but in 2009 (not so long ago), I did an "ultralight" 40-day on-and-off-road motorcycle trip without any electronics. A few years before that, I did a 10 week "backpacker without a backpack" trip with no electronics. This is still very possible.

The weight savings, the "escape from electronics" bonus... It's not nothing.

I'm not against it per se but it looks like somebody applied anti-anti aliasing to the time that displays on the lock screen to my phone. I don't see "this is a cutting edge user interface that's visually consistent", it looks like the settings icon is weirdly dark grey, kinda like somebody did some subtle vandalism to whatever strokes the edges of things.

That would be an unacceptably fat foldable. Foldables are 4.1mm to 4.2mm at the head of the class and iPhone Air is 5.6mm. Double that and add a bit for folding and you're still under 9mm (acceptable) with today's leading folders, and about 12mm (not acceptable) for the hypothetical Air.

People often underestimate how harsh their words come across to others when posting them on a web forum. If you intended them with sincerity, that’s fine, but one can easily read your words in the way that is often meant as a hurtful attack. Please take more care to ensure your words are clearly, sincerely kind in future.

Edit: On further investigation, I see we've had to warn you before about making that kind of comment relating to religion, and I note you posted a similarly dismissive reply last time. And indeed this time you've escalated, with the words "Cruelty is enabling clearly psychotic behavior."

Given that you're showing no intention to reform this pattern of behavior, it's time to ban the account.

Amtrak would benefit from a coach-class sleeper, like they have in India or in Eastern Europe. They just need coach benches that convert to beds. If, for a reasonable price, you could lie flat at night behind a little curtain, like you can in e.g. Indian Railways 2nd Class, it would change the game completely. Without that, you can only travel comfortably during the day, and trips are limited to about eight hours for the non-masochist. With it, cross country would be fine. It doesn't seem that hard. Lots of other railways do it.

Looking in the source tree, it doesn't look like it has it's own entry point. Zig is heading in the direction of a very verticall integrated compilation stack (I believe this is where most of the speed up comes from), so I'm not really sure of the utility with using it outside of the Zig world.

You guys are talking past each other.

One of you is pointing out that cars are a necessity for some in the current reality. The other is pointing out that we could change that reality like other places have.

You are both right.

I am very against the continuation of car primacy in urban design, but I live in a place where that is the current reality, so for all practical reasons I need at least one car in my household. I advocate for the changes so that isn't true and see that it is possible to live otherwise, but it isn't reality right now, so I own a car. Me owning a car isn't to "rationalize [my] bad choices and poor capacity for civic organization." I do it because the housing that I can afford, in the country that I live in is in an area where that is necessary. In the meantime I advocate for better transit and other options, but I am not omnipotent, and even those with tremendous amounts of power cannot make these changes happen quickly given the 75+ years of infrastructure and urban design.

You are tremendously mean-spirited and un-empathetic in proclaiming that those that don't agree with you are 'lazy' and 'not willing to sacrifice their own convenience for some communal benefit'.

Try understanding where people are coming from. Many believe as strongly as you do, and can provide just as many backing youtube videos, that cars are an unalloyed good. If you come at them this aggressively telling them that the places they live are just plain wrong, you will not convince them of anything.

As an aside, the Dutch aren't nearly as car free as you are presenting. They are in the top 25% for per capita car ownership worldwide, and have higher rates of car ownership rates than Denmark, Sweden, Greece and Croatia which isn't even all of the countries in Europe with lower rates of car ownership. Hell, they have more than double the rate of car ownership of Saudi Arabia, a country that subsidizes fuel prices to encourage car use.

Saying Congress is under autocratic control is hyperbole. There is a slight Republican advantage, smaller than the Democrat’s advantage during Biden’s term. The big beautiful bill didn’t sail through Congress, it took a while and the vote was close… a whole bunch of nonsense went on to get that through. If it was autocratic control, Trump wouldn’t be signing a million executive orders, he could sail them right through Congress and make them much stronger.

The important question to ask, is why the Democrats have had such a hard time winning at the polls? Clearly the message of “we’re not Trump” isn’t enough for voters, and voters also don’t like candidates being chosen for them (even Bernie agreed that the Democrats haven’t had an honest primary since 2008). The party is broken, and it’s easy to point the finger at the right, but the Democrats have been hemorrhaging voters and still seem unable to get their act together enough to win people back. There is a growing center that feels both parties have left them behind, and it would be great if the Democrats could wake up, see that, and move forward with an ounce of common sense to win them back.

Balance won’t be restored by demonizing the right, it will be restored by the Democrats getting their own house in order, before they claim to have the answers for the country.

At this point, both parties might be too far gone. I’d be happy to see them both implode and new parties emerge without all the baggage of the past.

The funny thing is that an oxygen-rich environment is a hell-hole! Oxygen is insanely reactive and will corrode anything. Even early life on earth found oxygen toxic. It was released as a waste product by early life and they were so successful that all that oxygen accumulated resulting in the Great Oxidation Event (https://en.wikipedia.org/wiki/Great_Oxidation_Event).

That likely resulted in many species going extinct!

In a lot of ways AI can give unskilled people just enough knowledge to be dangerous. The unfinished novel Bouvard et Pécuchet by Gustave Flaubert [1] revolves around this idea by telling a story of two clerks who come into a sizeable fortune and attempt to work their way through every branch of knowledge but failing to drink deep of the proverbial Pierian spring.

The most spectacular failure was when I asked it to make a logo for a project. The project has "cogs" in the title but that refers to Cost of Goods Sold not the physical object, so I specified that it should not include a cog a in the logo. Of course, it included a cog in the logo.

I asked it to help me create a business plan. Partway through it switched to Indonesian language, for no reason I could see. Then, after about two hours work on the plan, with about 200K tokens in the context, it stopped outputting anything reasonable.

I have tried to get it to help with Google Sheets formulae about a dozen times so far. Not once has it actually got anything right. Not once.

It's serviceable as a chatbot, but completely useless if you try to get it to actually do anything.

There were no firsthand accounts from his constituents. He never was able to provide a witness. You're using narrative to cover up events that never occurred or were rumors made into narratives. This is the source of the narrative illusion. "

"Multiple news reports in September 2024 detailed Senator J.D. Vance's inability to provide firsthand accounts or evidence for his claims that Haitian migrants were eating pets in Springfield, Ohio. When asked for proof, he pointed to anonymous "firsthand accounts from his constituents," which were later refuted by city officials"

Plenty of people do, many more than are in that server -- I asked some of my former coworkers and none knew about it, but we all spent a whole lot of hours tuning CUDA kernels together :). You have one perspective on this sector, but it's not the only one!

Some example motivations:

- Strange synchronization/coherency requirements

- Working with new hardware / new strategies that Nvidia&co haven't fine-tuned yet

- Just wanting to squeeze out some extra performance

Kinda depends on whether you're publishing open source software so that people can use it. And if you're not publishing open source software so that people can use it, why exactly are you doing it? If you don't want people to use it, GPL is the way to go. If you do want people to use it, MIT or BSD is a much better way to go.

Folks; use some common sense.

Results that are too good to be true! The probably are. If this study was reproducible (it is not) someone would have started using it, bragging about it, and we would have 'recovery vacations' to cruise lines that would de-age us by years.

Extraordinary claims require extraordinary proof, and this just isn't it.

Let's say that CUA, being a consolidation and standardization of previous software' keybindings, set a pattern replicated by lots of other software. But so did Emacs: there's a lot of software that, for example, binds C-n to "next item" and C-p to "previous item". Since you've brought up death, is that the right hill to die on? :)

Oh that's interesting! The US is portrayed here as this free for all country (limited unemployment money, health services, PTO...) but then subtitles are mandatory? That's cool! I presume we don't have such a law since the news sites I frequent don't seem to offer that for most videos (not counting youtube's autogenerated attempt for the few sites that outsource video hosting to google)

As for that video being small and not receiving thousands of simultaneous views: sure, but buying sufficient bandwidth is not a "hire better programmers" problem. You don't need to beat Reddit's skills and resources to provide smoother video playback. Probably the opposite actually: smaller scale should be easier to handle than reddit scale, and they already had that all set up

I responded because I care about science education and psychology education and wanted to correct the record.

When someone comes in with a bunch of links that can be confusing to people who don't know the field.

If you have motivation and strong enough confirmation bias you can find papers that claim to support anything. Even the existence of telepathy https://scholar.google.com/scholar?q=extrasensory+perception

That's why it's hard to have good judgment about a field unless you've studied it formally.

Mojo doesn't have C++-like exceptions, but does support throwing. The codegen approach is basically like go's (where you return a bool + error conceptually) but with the python style syntax to make it way more ergonomic than Go.

We have a public roadmap and are hard charging about improving the language, check out https://docs.modular.com/mojo/roadmap/ to learn more.

I was confused by my first several readings of the projectbluefin.io site, due in part to not having prior experience with some of the techs (e.g. their 2023 announcement said "Bluefin is a custom image of Fedora Silverblue by a bunch of cloud-native nerds. ... Originally Bluefin was "Fedora Silverblue for Ubuntu Expatriates". I ... wanted Silverblue but with a more Ubuntu-like desktop." I've never used Silverblue so that told me very little.

But I think I'm beginning to understand. Please correct me if I'm getting any of this wrong:

- Bluefin is, fundamentally, a container image that you run with your preferred container runtime (Docker, Podman, whatever).

- But where most containers are slimmed-down to run just one app, Bluefin is a Linux desktop in a container.

- Bluefin includes Podman in its image, so you can run other containers inside your container. (Yo dude, I hear you like containers...)

- Because Bluefin is a container image, updates are all-or-nothing, i.e. atomic. You download the updated image, then reboot into it next time you're ready to reboot.

- Installing other apps once you're running Bluefin is done via flatpak, rather than snap or apt or dnf or pacman. And there's a graphical app store that connects to Flathub. (I don't yet know what the offically-recommended way is to install software that isn't yet on Flathub).

Anything incorrect in that list? Anything major that I left out?

(Edited only to add a newline between bullet points, because I didn't realize that Hacker News doesn't implement that part of Markdown. The fact that asterisks around words gives you italics fooled me into thinking that more of Markdown than italics was implemented.)

zig has a cross-compiler frontend (zig cc) which can be used as a drop-in replacement for a custom sysroot + binutils + gcc for several platforms. I've used it to build OCaml cross-compilers that only depend on zig itself (https://www.chrisarmstrong.dev/posts/ocaml-cross-compilation...).

There are other projects that have used it in a similar way too.

If you have a truck full of A100s, it's "extremely valuable" but also perishable goods.

Right now, any workable AI hardware is valuable because the market is not presently saturated, and people are in a "buy what you can get" mindset.

Once the market is reasonably saturated, people will get more selective. Older parts will be less desirable-- less efficient, less featureful-- and if you have trucks full of them to dump on the market, it's going to depress the price.

It's like the PC market of 30 years ago. You got a new Pentium-100, but you could still sell on the old 386/16 for a fair amount of cash because for someone else, it beats "no computer". That market doesn't really exist anymore-- today, you may as well just leave a Haswell or Ryzen 1000 box at the curb unless you want to spend 6 weeks dealing with Craigslist flakes for $30.

> Are you campaigning with your city council to favor more/better public transit options?

Why would I do this? It's just not possible for public transit to provide equal quality of service to a private vehicle unless I lived in one of the most densely populated areas on Earth, which I do not (though I do live in a major metropolitan area).

On top of that, my area has spent tens of billions to expand the subway system, to little effect and with many, many delays and cost increases that indicate that the local government is not capable of successfully managing a large scale infrastructure project.

> Are you discussing with your neighbors about changing zoning laws so that small business and shops can be located closer to you?

I already live in a pretty walkable area and things are already trending towards making things even more walkable, so no I'm not because it's not needed.

I think the internet may have driven some people hysterical or something, or they are making extreme comments on purpose to instigate, or create FUD.

The U.S. is a huge country, so experience varies by region. But in populous regions, shopping centers and restaurants and clubs are filled with folks doing their normal thing. Businesses are doing their normal thing 9-5 every week, and local and state governments are running their ship as best as they can while navigating a different type of presidency. Property prices are up, and unemployment is relatively low.

There are concerns, but that’s normal for every country. It’s better for concerned citizens to reach out to their representatives to talk about specific issues than to let possible nation state actors rile you up into extremism. Democracy is alive and well in America, but yeah it’s tougher for liberals and globalists to push anything that’s not America First.

People exist outside of your vehicle. Danger can be something that you impose onto others by operating heavy machinery. It can also refer to danger of property damage or non-life threatening injury. You and your car might be fine in a parking lot incident, but the kid that you ran over will not be.

For reference, in the US, for just reported vehicle accidents per the National Safety Council:

- 20% of all accidents occur in parking lots

- 500 people per year are killed in parking lots

- 60k injuries per year in parking lots

Given the low speeds inherent to parking lots, and the extremely low share of miles and time spent there, it is a remarkably dangerous place. It doesn't take a genius to figure it out; parking areas are by definition where humans and heavy machinery operate in the exact same spaces.

This has been my experience also. Curious if this will improve with just more training data, or if another method will need to be introduced.

Building models in code like this is really cool; it’s great to be able to import, for example, a “gears” library and automatically generate the geometry for complex bevel gear setups. I’ve seen this approach used for more than CAD too; there’s a Python library (GDSFactory) for building photonic ICs in code as well, and I’m sure plenty more.

This workflow is a big motivator for my data notebook project (https://mnty.sh/#serenity), since I would like to build everything for a project in code and have visualizers for each component in one notebook.

I think we are talking about pretty much about the same phenomenon, but you are using the difference is the scale as a justification for its effects. I don't get why.

> And American cities were being reshaped by this.

It's one thing to have cities building infrastructure in their existing areas to make room for cars. It's another to have suburban sprawl of the post-war, where cities would grow exclusively by spreading to the outskirt and building single-zoning areas.

> The USA has many cities that were highly populated before cars. Particularly Manhattan.

And there were also many big, developed cities which had their downtowns destroyed in favor of highways. Manhattan being an island protected it from this fate, but lots of cities in the Midwest or Texas had walkable areas.

The dominant constraint is usually road capacity during peak hours. You need a certain number of large buses to handle that, and those buses are cheap to use outside peak hours.

Ideal bus size may go down if peak demand also decreases. For example, if working from home becomes more common. Smaller buses may also become more viable when direct bus lines are replaced with rail lines and feeder buses.
