Everyone claiming that the autopilot is at fault for stopping suddenly get something very important very wrong: Stopping a car must be possible at all times. Any automation in a car should always be able to stop the car as the safe default. The same holds for human drivers, of course: Consider the possibility that the vehicle in front of the Tesla just lost some of its load. Of course the Tesla then has to stop suddenly. Considering this behaviour a safety problem is a lazy excuse. At worst, it is a nuisance.

As for the safety distance: This is a valid point. If the Tesla has not kept a safe distance to the following car when changing lanes, there is a problem with the automation. It should always be as defensive as possible. I don't see that from the police report, but the video shows the distance to be rather short, maybe two car lengths. Call it 10m. The second car doesn't really seem to brake very hard (no emergency braking assistant?) and that crash is definitely on the Tesla as it cut the distance, unless the speed limit in that tunnel would be around 20kph or so. But now it gets interesting: The third car does stop successfully. The big pileup happens afterwards.

In conclusion: The big pileup happens because the third car suddenly stops - and rightfully so but the following cars don't keep their distance to that third car. The Tesla getting rear ended is just a lazy excuse for these drivers that simply drive recklessly.
There are device testers where you can check if the PE resistance and isolation resistance of your mixer are within spec. If not, it is a broken device.

The grid, wiring, connectors etc can also be tested.

In Germany any company is required to have external contracters carry out these tests every 24 months due to work safety laws, this test is called DGUV and I think there is an ISO equivalent. If you ever have an electrician over that is worth their money they should be able to carry out those tests.
Flight sims are great in VR. E.g. Varjo XR-3 is part of a virtual reality-based training solution for aviation training. The headset has high enough resolution so that all instruments and their texts are readable.

I've been literally playing Cricket VR for 4 hours everyday since X-Mas.

For someone who played college-level cricket, this is a dream come true for me and the sensation of hitting the ball in the middle of the bat is mind blowing.

But, here's the kicker. In real world, If I had play 120 pitches (baseball equivalent), I'd have to wait for 4 hours. In VR it could be done in 30 minutes.

I've already lost 7 pounds and feel energetic.

I can't imagine how playing sports, music, concerts in the next 5 years is going to be in VR accelerating the skill-mastery process.

People who diss VR is the same kind who diss AI. Mixed Reality / AI will enhance productivity of everyone leaving the luddites far behind
Tort is civil law. Criminal liability still can't be insulated.
For your average home user, it's probably the better option, even if I as an individual don't like it at all. Not every person's specific needs/wants are the same. I've had encrypted Linux volumes become inaccessible because of a changed password when I wasn't able to come back to that system for a few days after and frankly forgot the specific combination of words used.

Luckily I did have backups... but it could have been worse. A mom losing all the baby footage of their child because of lost/broken/damaged encryption is not a pleasant thing to explain to someone.
I figure 1962 was Peak Hollywood.
I'm of the opinion that we're just regressing to the pre-COVID trend line.

Many metrics have a huge pandemic bump that's just approaching the pre-COVID trend line. I suspect we'll see a slight overcorrection. First dipping below trend, then bouncing back up a bit, before finally returning to trend line.

Companies will adjust to supply chain issues. Workers will wisen up and move jobs. Home demand will level out with supply. People will return to "normal" work areas.
I know many (european) electricians that would label that a wreckless action. It would also be illegal over here.

Weirdly enough Samsung fridges work over here without tripping RCDs.
>Project Daedalus

That's not a manned craft, which is what we've been talking about so far. It also doesn't have the deceleration stage - Daedalus would flyby Barnard's Star at 12% the speed of light. If you hit a rock along the way at that speed, you're not gonna get any pretty pictures :-)

>5 years ago, would you have imagined ChatGPT or Stable Diffusion?

Absolutely! I think most people in my industry would have imagined ChatGPT or Stable Diffusion as they appear now 20-30 years ago, let alone 5.

>And all of these technologies were much more infeasible compared to interstellar travel (and yet we did that).

See... again, most of the problems faced by the "smaller" feats like airflight are engineering problems, not "this breaks Einsteinian physics" problems. When you're talking about interstellar flight you're running up hard against many fundamental constants of the universe, not just "we can't do that yet"
I am designing two things.

It should be possible to change architecture from changing a text file. Which is also a diagram.

I am designing a state machine formulation for complicated systems and a multiplexing format for messaging. In theory the state machine formulation can be rendered to a diagram.

This state machine is similar to Prolog and BNF parser format. It defines a progression of states for async/await. I think the format would be useful for microservices and multithreaded software.

next_free_thread = 2
task(A) thread(1) assignment(A, 1) = running_on(A, 1) | paused(A, 1)

running_on(A, 1)
thread(1)
assignment(A, 1)
thread_free(next_free_thread) =

fork(A, B)

| send_task_to_thread(B, next_free_thread)

| running_on(B, 2)

paused(B, 1)

running_on(A, 1)

| { yield(B, returnvalue) | paused(B, 2) }

{ await(A, B, returnvalue) | paused(A, 1) }

| send_returnvalue(B, A, returnvalue)
This also works in MySQL 8.0.19 and above but the syntax of the CTE example needs to be tweaked to use the ROW() constructor:

WITH countries (code, name) AS (
SELECT * FROM (VALUES
ROW('us', 'United States'),
ROW('fr', 'France'),
ROW('in', 'India')
) AS codes
)
SELECT data.code, name FROM data LEFT JOIN countries.code = data.code;
That's terrible. On the other hand, airports for me are guaranteed to be awful, and I've always enjoyed the Amtrak. If I'm in a hurry to get someplace I'll take a plane, sure. I wish we had high speed rail in this country (or I'd never fly again except internationally) but of course we don't. If there's no particular rush I'll take my sweet time on the Amtrak, and if it's delayed for 30 hours - like I said, you'll find me minding my reading with no complaints.
>Michaël Peyrot argues that several of the most striking typological peculiarities of Tocharian are rooted in a prolonged contact of Proto-Tocharian with an early stage of Proto-Samoyedic in South Siberia

>Some modern Chinese words may ultimately derive from a Tocharian or related source, e.g. Old Chinese mjit (蜜; mì) "honey", from Proto-Tocharian ḿət(ə)

Wouldn’t be surprised that cause honey in modern Uralic languages are also very similar. Méz in Hungarian, mesi in Estonian.
Interesting app, curious what the use case is?
Mac OS has always been good at managing resources for background apps (in my experience). I don’t mind if I have some extra open apps. I think I even have the setting activated that hides the ‘dot’ to show ‘running’ apps.

Honestly, if you look in activity monitor there are over a hundred apps running without any windows being rendered.

Maybe it’s because I’ve always had more ram than I need?
90 minutes boot time...

I have a feeling the summarized age of the hard drives in that system exceeds the age of the United States itself (which is 247 years). When fsck was introduced in 4BSD in 1980, it checked every filesystem on boot because it had no better idea. If this thing is, say, forty years old then that's exactly the right age for this...
Wondering why this for profit organization isn't on the hook for tax fraud
The entire history of mineral and energy extraction tells us that once dense deposits are exhausted extraction costs substantally increase even in the face of more sophisticated technology.

eg: Oil was once extracted by sucking it out of a surface pool with a pump .. and now we are fracking for gas fractions.

These "there are XXX tones at YY ppm (or ppb) of Z in the crust or ocean" calculations are almost always impractical wishful thinking economically infeasible bullshit.

For example:

Have a shot at guesstimating the tonnage and value of Palladium (used in catalytic converters) in the near vicinity of road surfaces - it falls there as by product waste.

Now have a stab at the cost of ripping up and processing the central north american road surface to extract Palladium.

Worth it?

It'll be cheaper once we abandon cities and roads, of course.
> Whoever has more weapons get the land.

Aliens might not actually be land-based creatures like us. Those who evolved on planets entirely covered by liquid (water or otherwise) might even find the idea of "land" fairly strange.

(It's actually quite interesting to ponder the stages of discovery that liquid-based intelligent aliens might go through. First they might discover air (and land if available) and only after that space as another outer layer. I suppose that adds extra thrill we didn't have. Supposing of course that conditions there allow gas and liquid to exist as separate phases. Planets above criticality would probably be weirder still? Would any bottom rocks under the supercritical fluid still count as land - as opposed to "sea floor"?)
If it’s your one hour of exercise a day, you can make it work. But yes, keep young kids away, especially if you’ve learned to punch or slash really hard in your VR shadow boxing or fencing experience.

Immersion isn’t really the problem in that case, the experience just needs to be distracting since your primary goal is to sweat. VR fitness is the killer app.
> Roads are everywhere -- there's a road leading up to most people's place of residence.

But parent's comment was aimed at the one lane for self driving cars comment.

So I don’t see how you comment could apply to it. Yes we have roads leading up to almost everyone’s house. But in the case of a dedicated self driving lane proposal it would be as impractical As giving everyone a railway track leading to their home.

> Trains are not owned by individuals.

Exactly. So instead of building infrastructure to improve moving a few people at a time, improving infrastructure that helps move a few hundred at a time seems like a better investment.

We have 1000s of years of history, wars, and imperialism to draw on. It is possible to evaluate the extent of China's imperialism without comparison to the US.

Is China increasingly imperial? Is China engaged in tactics to undermine, divide, or conquer other countries and peoples? Is China expanding their military presence around the world?

The answer to all three is yes

Your windows machine likely have more lax permissions for the internal LAN. It's easier to try and install a keylogger, and steal your passwords on various sites, card numbers, etc.

This all gets bought and sold on black markets, and gets used weeks and months after being stolen. Spam sent covertly from your mail account, mystery charges on your CC, etc. Not pleasant. At the worst case, a full identity theft, then behold a $30k loan taken in your name, for you to repay with interest.
When do you find reusing a promise useful? I know one canonical example is a loadable hashmap as in Concurrent Programming in Java, but I was curious if you knew of other examples.
Do isotopes of any element exist with all three of these properties?

1. Radioactive with a half-life short enough to be dangerous (e.g., not bismuth-209) but long enough that waiting for it all to decay isn't a feasible way of getting rid of it (e.g., not francium)

2. Produced by nuclear reactors

3. Not usable as a fuel source in any breeder reactors

If not, then why is there such a thing as nuclear waste?

It does. And then also actually maintaining a safe distance can be difficult simply because people will immediately merge in there (and then brake in front of you, because of course now they're too close to the other car).

Maintaining a safe configuration of cars on the road is the collective job of everyone who is driving on it; and conversely, it takes just one person to ruin it for everybody who is doing the right thing. So it really needs to be a part of the culture of driving for that to work. And we don't have that in US, unfortunately (though, to be fair, there are far worse places to drive in).

From interviews of scientists in places like John Michael Godier’s YouTube and similar, I do sense scientists see the value and some demand to be able to investigate such things. I think one recent interviewee even mentioned having drawn up plans for building up some readiness and a project to do a fly by of Oumuamua.

Further, rocket launches seem to be an emerging market in that the price to launch comes down as more capability ramps up. So it’s possible the market might answer this before government.
> And that LNG facility was my point, that’s far less useful once Russia’s pipelines open up again. It’s a massive investment with limited long term gain on top of also paying higher natural gas prices.

It is strategic. Sometimes you do need to pay more to keep some options open and diversify your sources. The last year has shown how foolish it would be to get back in bed with Russia. Buying their gas is fine, getting dependent on it is not.

That's the fun/smart/evil thing about how Kroger did this...Zenith was regional. Only 2 or 3 state area, KY/IN/OH if I remember right. And Kroger due to its sheer size became their only customer. Or perhaps the company didn't even exist prior, it's hard to actually research. So of course, in reality, Kroger still has direct control.

They can do this in every region, of course, to keep any company from getting too big for its britches.

Some folks use data lakehouses for data fishing or data powersports. Personally I just like to sit out and enjoy the data sunsets on the warm nights.

We still need it, as the damaging UV light isn't fully blocked just mostly absorbed. Most of the UV-C light is blocked, which can cause serious damage. Then there is UV-B and UV-A. They all can cause sunburn and some of it will still reach the surface.

The desity of the ozone layer is also dependent on many parameters and not homgenous. You still have different exposure szenarious, depending on altitude and geographic location.

We could use less and hopefully see much less skin cancer in the coming decades.

You have options that would give you more flexibility on travel times you simply value the lower cost over the convenience. That’s not a train problem that’s a choice you have made.
Sounds annoying, which country?

Where I live the national railway carrier lets you refund or exchange your tickets and seat reservations freely up until 15 minutes before the departure time, most ticket types are valid for a day (so you don’t have to buy one for a specific connection) and the prices are, I believe, more or less fixed. The delays are inevitable I guess in most larger networks.

I don’t take the train that often, but my experience is generally pretty good, especially as I’m starting to hate driving.
11 months is no time at all for any kind of large-ish project. And small-scale projects are getting harder due to the economic situation as well. You just cannot do much of anything in 11 months.

Well that's part of the answer. If enough of us flash the cars with annoying lights then maybe manufacturers will get the message.
As someone who are involved half a dozen projects, high level architecture diagrams are extremely useful. This is especially true when meeting with stakeholders in other teams and explaining what we need to do to accommodate their requests, and also when onboarding new resources. The way I use diagrams, they should not be code as that is just added complexity without any benefit
“Rust grew out of a personal project begun in 2006 by Mozilla Research employee Graydon Hoare. Mozilla began sponsoring the project in 2009 as a part of the ongoing development of an experimental browser engine called Servo. The project was officially announced by Mozilla in 2010.”

More or less. The chairs are hostile to stop you from getting too comfortable. I've had 6 hour layovers before and had to sleep in those terrible chairs under fluorescent lights. On the last flight I took there was barely any good near my gate, there were like 4 bars instead. You can't leave your luggage anywhere, so you're dragging it all over the place. You get jammed like sardines into the plane, and you can't stretch your legs. You can't really relax because you have to stay abreast of announcements, in case they change your gate or cancel your flight or what have you. Everyone is on edge. Et cetera.

On the train there's more room, you can move around, and the atmosphere is more relaxed.

Some people like planes. I saw an HN comment where someone said they took lots of "flights to nowhere" over COVID and used the plane as their office. I don't understand that at all. But to each their own.

I will say the views are unbeatable.

It’s marketing BS designed to look good as a whiteboard diagram. “See all your disparate data sources here? That’s your problem. Your competitors have all their data in a data warehouse. You like warehouses? No? Neither do I. Stuffy, stale old places. You need all this data to flow into a central living breathing data lake. You like lakes? You do? Well now one thing to be aware of is to really appreciate the data lake, there’s nothing like a data lakehouse…”
This is a big deal for crypto. Once there's a legal framework around crypto people will be more likely to trust the infrastructure around it. The big test is whether El Salvador will be able to enforce the laws they pass. Right now it's a hard no. Corruption is rampant in El Salvador so it's hard to trust anything they do but maybe the President there can do something about it and turn things around.

But any way you look at it it's a plus for crypto since once one country does it other countries will follow just so they don't get left behind. I expect other small countries to move forward with legal crypto frameworks.

They currently operate on disjoint sets of roads, so they can only be roughly compared, and in rough comparison they do not behave differently. Of course if operated on the exact same road (which, again, is currently impossible) their actions would not be the same in every detail, just as different humans or even the same human driving the same road multiple times wouldn't. But that doesn't mean that there's necessarily any consistent difference that would enable a driver to use the information of which one is active to improve their predictions of the car's behavior.
Well, for example, MySQL/MariaDB using utf8 tables will instantly go down if someone inserts a single multibyte emoji character, and the only way out is to recreate all tables as utf8mb4 and reimport all data.
It's not the time, it's the unknown/unseen factor that's making it likely or unlikely. You think you are seeing lighting striking a tree. But maybe what you are actually seeing is lighting striking a lighting rod.

Lightning will not strike a TREE again because usually it destroys the tree in some way, changing it's height. But for many other things (buildings, mountains, etc), lightning will happily strike it over and over again.

Is the car in a ditch for a truly unlikely reason, or there a hidden lightning rod there? Perhaps you shouldn't assume a seemingly unlikely event won't happen again.
