i love the idea of 3d printing a building. i dabble in 3d printing already, making parts to facilitate my other hobbies, and it would be great to deploy a machine that prints a structure.

I own a business framing houses, it would radically change the dynamic in that field. However i am confident i could execute in that new environment, given the technology.

Makes me want to start an open source 3d building printer foundation.
Funny that some people commenting on the video immediately claim it is fake. This kind of abuse was extremely common when CS was in perpetual beta and voice chat first started being a thing. There is clearly a subset of online gamers, especially in FPS games, who cross the line from joking/hazing into abuse against anyone with a female name or voice.

I sometimes wonder what makes these people knee-jerk deny such obvious behavior anyone can observe?
Layoffs are happening to blue collar works also.
The consolidation of movie studios (mostly into Disney lately...) hasn't been helping either. There used to be plenty of small studios that would do "weird" stuff - it wasn't going to be a huge commercial success, but it would probably make back the modest budget it had.

There's always older films to watch. I'm at a point where I'd far rather put the time into something older, with solid actors, than watch the latest and greatest mostly-CG special effects laden [whatever]. That most of those movies are unwatchable unless you're "deep into the fandom" doesn't encourage me to invest in them either. And if it's not those, it's the "How can we prequel all the popular things," even when it makes no sense at all. To yell at a cloud briefly, Han Solo doesn't need a prequel. He's a standard drifter archetype, and to nail his past down doesn't do the character any service at all.
This reads a little like the early days of self driving car optimism or factory roboticizing. Everything looks so easy with an easy rollout, but enjoy the long tail. To me, car companies and Amazon have high incentive to use robotics and a really controlled environment and they still need a lot of humans. Those use cases will be more thoroughly solve (IMO) before any variable-environment use cases get fully automated. I'm not a pessimist and I really want a lot of automated stuff, but I don't think the tech is there yet.
>It's no different than any other traditional broker going out of business (which isn't common but does happen).

There are tested procedures in place that are know to work when dealing with traditional brokers. The crypto space doesn't really have such things.
Layoffs? Maybe. Paycut? Not at their existing companies. There's a case to be made that too many tech companies scaled too quickly. Fundamentally, Coinbase is still a solid company, they may have overextended hiring but their core businesses are very profitable.
Meh, it seems like all infotainment computers get outdated a lot faster than the car, and they don't even have an advantage by being brand new because the manufacturer just slaps on something "the cheapest and slowest computer you can find, and just tolerable enough" to save costs.

The car should just offer HDMI input for the display and speakers, and allow the computer to be upgradable. Even the display should be a module (say someone wants to upgrade to 4K OLED...), which makes me think the DIN got it right: https://www.bestcaraudio.com/what-is-a-double-din-car-radio/

> Tesla sells solar roofs and power walls accessible to every person in US. Is it an evidence electrical grid is not a natural monopoly? No it is not.

Unlike competing video hosting platforms, solar roofs and PowerWalls are not the same product as the electrical grid. There is some substitution effect, but they generally work in tandem. Most solar and PowerWall-equipped homes are not fully off-grid; it can be done but it takes a lot of storage to ensure you never run out of power with normal household use. (My 5.12 kWh of solar panels generally result in a net surplus of energy each month, but even so I've calculated based on daily net consumption over the last ~16 months that 100 kWh of storage—7-8 PowerWall 2s–would still leave the system depleted by the end of the day 13% of the time. Granted, that includes a three-week span last February where the panels weren't generating much of anything due to snow cover, but that wasn't the only occasion where it would have run out.)

The "natural monopoly" of the electrical grid, for those who believe in such things, lies in access to the physical right-of-way for laying cables to everyone's houses. I'm not sure I'd call this a natural monopoly as the difficulty newcomers face in accessing the right of way (or depending on how you look at it, the ease with which the incumbents claimed the right-of-way for themselves, often through eminent domain) is mostly artificial. Regardless, while it is a true barrier to entry favoring incumbents over the competition, nothing of this nature applies to either Tesla's solar + storage business or to YouTube.

> The network effect does give Google that overwhelming advantage over potential competitors.

The network effect is certainly an advantage while it lasts, but networks are highly mutable, to the point that I wouldn't call this a barrier to entry. For example MySpace had major network effects once as the dominant social network—right up until it was completely replaced by Facebook. Crowds can be fickle like that. There isn't even a social network effect for YouTube like there is with Facebook, where you're strongly incentivized to stick with the same system your friends are using. If you upload your videos somewhere else—as many people do—everyone will still be able to see them.

Of course that doesn't guarantee that any particular experiment in competition will succeed. As you say, Google Video failed to gain traction, and it was hardly the only one. But even so, YouTube has competitors. The failure of Google Video does not imply that YouTube's position in the market is inviolable. They retain their place only so long as they continue to provide the best service.

My grandfather was recruited by Pan-Am for the Pan-America-Africa project. (Hey kid, wanna learn how to fly?) and spent the WW2 years flying into many of the places mentioned in this article. It's great to read about where he spent his time before settling down as a commercial pilot. Much later on he had to dodge an errant Agean rocket that was flying where it really shouldn't have been. I bet that was a hell of a debrief.
I had a very similar experience in France! Do yourself a favour and get a dedicated bike GPS and plan the best route ahead of your trip. It's much more enjoyable this way!
Yeah I posted about it above and people said it works fine. I wonder if it depends on who you original carrier was or something? I'm going to try again!
> You seem very confused about what the scientific method is, and how it eliminates the need to trust scientists instead of science.

You seem very confused about how science is implemented.

The scientific method absolutely does not eliminate the need to trust scientists.

Have you even heard of ethics boards? Institutional Review Boards? The Hippocratic Oath?

You are trusting in scientists in the collective. You think that somehow makes the scientific method immune to the problems of human behavior. If anything, it exacerbates it, and it is only because of the diligence of scientists, almost completely orthogonal to the scientific method, that progress is made.

> eliminating falsifiability

It's hilarious to watch you claim this, while I've listed multiple examples of how we investigate scientists OUTSIDE of the scientific method. Corruption. Blackmail. Bribery. Because I recognize that we do in fact trust in the scientist, and I know that trust can be misplaced, I am MORE alert to the problems that can corrupt scientific findings than you are.

You would seem to be dumbfounded, "How on earth could TWO scientists BOTH be bribed by the same corporation?!?"
> Speech is the most important non-violent right that we have

Really? More important than the right to vote? Than the right not to be arbitrarily detained? Than the right to a fair trial?

I strongly believe in the importance of free speech when it comes to true statements or criticism of the government. But the idea that the right to spread deliberately false information or directly incite violence is not just a fundamental right, but the most important fundamental right? Honestly, I just don’t find the argument very compelling
Micro-services is about partitioning based on functionality and features -- so I think more often than not, 99% of the microservices use 10% of the storage and 1 microservice use 90% of the storage, and you're back to solving the problem of horizontally scaling your storage regardless of microservice vs monolith.
AFAIK Ola Melzig (the m-m-pr.com guy) is off working on the US version of the song contest [0], and there isn't any tech diary for this year - which is sad :(

There's a similar tech blog for last year [1], but it's sorely missing Ola's own funky style.

These have always been great reading for someone more used to being a tech than a guest at parties.

My muscle memory has been so conditioned by Google Maps (on a computer rather than a phone) that the main reason I don't use Apple Maps is the zoom in / out actions on trackpads are reversed and the drag action is different. I think most other maps systems like OpenStreetMap and Mapbox use the Google-style actions too. I just cannot get used to the Apple ones and it frustrates me as I'd like to use Apple Maps over Google Maps as I'm more convinced about Apple's privacy stance, and don't mind Apple Maps having access to my contacts, making it easier to say "direction to X's house" rather than having to type in an address or postcode.

Kitchen tap water only, no bathroom tap water.
Yes. I knew this as list fusion.

Note that Rust doesn't need to do this because of the way `iter_into()` and mapping works. List fusion boils down to removing interior `.collect().iter_into()`.

There is something to be said for designing APIs so that you don't need such rewrite rules, though, of course, the need comes up eventually anyways, so rewrite rules end up being kinda necessary.

I dont think inventory is their issue, but rather the fact they are a lender more than a dealer. They just make a lot of questionable loans and repackage them for sale, sort of.
> I'm shocked that this story hasn't had significant discussion on HN.

It got quite a few votes before.

It's a great story and I'm glad I caught it today, I upvoted it but ... I don't really have anything to comment. I have no informed opinions to offer, related anecdotes to share, or related stories I can think of right now. It's just a great story. Comments aren't everything.
I went to our new Carvana in Houston last week to see it work. The security guard type who was on duty was almost openly hostile. There was no acknowledgement that I might be a current or future customer. How would he know?

This person was so unpleasant, I decided on the spot I would never buy a car from them, no matter how cool the vending machine or how great the deal.

Having worked in car sales and finance, I can tell you this is a big mistake. If Carvana's plan is to replace dealership staff with a robot and a security guard, then they will soon be out of business.

I very much disagree.

I already have summarized it. All I've done since is correct people being incorrect with regards to my summary.

No need to go that far. If you're just looking for the edge of where the capabilities of CSS animation fails, consider the pseudo-physics of various direct manipulations in touch UIs: eg. the bounce when you swipe to scroll and reach the last item, or swipe down again to refresh, or swipe to fling cards aside left or right, or pinch to zoom past the last zoom level, etc.

In some cases you could get a good-enough result by animating from arbitrary (ie. user controlled) starting point to one or more fixed end-states (eg. Three "flick right" animations, one each for flick up and to the right, right, or down and to the right), but at that point you might as well just use an animation library.

>2024: autonomous machinery takes over

Mass-grading is the only part of construction anywhere close to this that I’m aware of. Manufacturing processes for building materials are really impressive, but it’s a different story on the job site where you constantly have to make judgments about the work environment. I think most of the low-hanging fruit for automation is in the design process.
Powered-Lift just means that they aren't using their wing surfaces for lift take-off/landing but are using them for lift during normal flight. They [edit:might] be able to auto-rotate down in the case of a powerplant failure just like a helicopter.

Here is the exact definition:

> (425) Powered-lift. A heavier-than-air aircraft capable of vertical take-off, vertical landing, and low-speed flight that depends principally on engine-driven lift devices or engine thrust for lift during these flight regimes and on non-rotating aerofoil(s) for lift during horizontal flight.
Thanks for your response. I definitely agree that bikeshedding can be a problem in code reviews and bikeshedding itself is best avoided for sure. Automating that stuff away with linting tools is a good tool in the toolbox for that, and so to is having some conventions and/or understanding and accepting preferences of different team members and not actively engaging in bikeshedding over things that are a difference, but not a difference that makes a difference.

In my experience the value of code reviews doesn't come from nitpicking those types of things. That's by far the worst part of code reviews and is definitely annoying but mostly becomes not a problem if you employ the abovementioned tools/practices. Rather the value comes from others picking up mistakes in the quality of your implementation that arises from some gap in knowledge that the reviewer is able to pick up on and fill in. And to that end they're absolutely essential. They're not simply a box ticking exercise either - the amount of code reviews I've both done and received that picked up on actually important issues is in the high double digit percentages. I would take no code reviews to be a major red flag.

The behind the scenes for Eurovision are quite interesting. Supposedly it's the second biggest event production in the world after the Olympics.

There is no single point of failure, there are two separate master control rooms, two separate sound mixing rooms, two separate electricity feeds, tens of thousands of kilometers of cables, all the microphones are dual connected on both analogue and digital wireless, ...

The cameras are pre-scripted and auto-switched, a bit like on auto pilot, but the operator can override them if needed:

I get the sentiment but how exactly is raising literal millions in funds 'middle class' in startups? If I had a million dollars I could put together a team of founders who needed about 20k per year each to survive and we wouldn't need to raise until shit was actually finished with substantial revenue. Granted, this assumes you're not in Le Bay (I know) and your expenses are very low (like owning your house) but in my mind this is how startups should be done.

Get a bunch of people to move into one of the founders houses. Sleep on the floor if you have to. Have a coffee pot making bulk coffee for the whole house day-over. Live on nice healthy foods that require no cooking so you can code more. No take away obviously because its horribly over-priced. Plenty of cash for hosting services. Obviously no meme shit like cloud hosting. Use real servers for everything. There are even enough services that provide free resources to startups that you may not need to pay for this. You want to avoid the trap though: becoming dependent on services designed to screw your time and wallet later on.

Anyway, it seems like investors in startups only care about companies with million or billion dollar potential. You hear much less about people who build smaller profitable businesses, period. I'm guessing if it's a small business with limited growth potential you just have to bootstrap it with your own money.
Could such a setup be used for streaming movies as well? If yes, could you explain how?
shoot, I forget...but wasn't there a ton of material written re the Naval Battle of Guadalcanal? I vaguely remember the name Samuel Eliot Morrison. Also, as a kid, I remember a Natl Geo style writeup by Robert Ballard since he led an expedition to use ROVs to look at wrecks on Iron Bottom Sound.

I think Lee got a bit of luck too...since all of the rest of his fleet got blown up around him and the Washington was able to take advantage of the fact that all the attention were on the burning destroyers and the South Dakota, while he could take shots at will.
At a minimum, it is logical to assume a human life biologically begins at the same time it ends ... using brain function. Any argument that a fetus with nothing but a brain stem, or a brain damaged adult with only a functioning brain stem remaining, is 'alive' is based on "sanctity of life" or other religious or pseudo religious beliefs.

As an atheist, I have no qualms or guilt about choosing to pull the plug on any biological "human" without a functioning cerebrum and cerebellum.

The third trimester is when the abortion debate gets at all tricky for me.
You still haven’t actually made a single argument, just sniped with useless ad hominem. Do you actually have anything to say?

Again, I understand why religious thinkers want to drag the conversation into epistemology; it’s a complex rats nest in which their sophistry thrives.

However, we don’t need to touch epistemology to discredit sciencism as internally inconsistent, and so I haven’t, and have no interest in arguing the value of anyone’s faith-based epistemological ideals.

Religious ideology is religious ideology regardless of whether it claims orthodoxy over science, god, or neither.
Absolutely. But now more than ever it's about the brand, and not the individual. But I think this primarily applies to mainstream music where the artist is likely to have a few hits over a couple years, only to fade out (unless they can build the brand). Go outside mainstream music, and chances are that you'll see something completely different.
Ah, interesting! I usually only hear about crypto/blockchain in a negative context (new XYZ-coins that are pre-mined, environmental impact, plugged into games for new microtransactions, etc), so it's interesting to hear about a potentially legitimate use case.

To be bluntly honest, I responded because I thought you might be advocating for violence against someone entirely based on their nationality |OR| that I completely misunderstood what your comment was about (which I definitely did here; sorry for interpreting your message the wrong way).

Even with it just being a discussion board, I would really regret not at least leaving a comment asking for clarification. I'm glad I did in this case, as I turned out to be completely wrong :)

One final “bad”: the update operation (known as replace) is also slightly lacking in my opinion. I’d like to be able to update an object with a partial fragment, eg:

The op

{ “op”: “replace”, “path”: “/foo”, value { “a”: 3 } }

Applied to a base object

{ “foo”: { “a”: 0, “c”: 1 } }

Will update “a”, but will throw away existing property /foo/c.

This is dumb. The other problems like it are dumb. Like so dumb it’s hard to not ruminate, so everybody here that complains is right. But not much so that the technology is void of use as some seem to suggest.

It’s so funny that JSON Patch 2 hasn’t come out with more extensions/improvements. Perhaps this Ycomb thread is the little push over the edge that we need to get a ball rolling!
Well perhaps they should have listened to my warning that I outlined [0] rather than buying on the direct listing price of >$400 a share on the first day.

I'm re-reading Atlas Shrugged now for the second time (first time was 10 years ago), I enjoy it even more now, there are many things I found boring the first time around in the first few 100 pages, but now that I know where it is going I'm picking up a lot of subtle things that make the whole experience more interesting.

I don't understand why HNers sometimes are so anti Ayn Rand, it seems to me that Dagny and Hank are true entrepreneurs. And if you ask me, very ethical because they absolutely abhor influencing the government to get what they want and they are ruthlessly honest with very transparent intentions. Very refreshing. I really would have liked to learn Ayn's opinion on modern surveillance capitalism, I bet it would match the prevailing opinions here.

Moreover, her take on female sexuality must have been revolutionaire at the time, I mean in the 60s Kirk was considered progressive while looking a female medical dokter up and down and remarking that he could not get used to women on the bridge. And here is Ayn presenting Dagny Taggart, with modern (well almost, don’t quote out of context) views on female sexuality even in 2022.
You mean the leadership of the Atlantic? Their traditional brand is "left-center" so this is pretty squarely in the wheelhouse for them, I'd say.
