Aero models are actually much simpler than racing tyre models.

Most older flight sims used a lookup table for aerodynamic forces, which is gives a pretty decent model for most of the flight envelope. Newer sims do model the airflow around the wings but it's still relatively simple.

Tyre models have similar history, most models are empirical and based on the Pacejka tyre model with some adjustments, not quite a lookup table but some very basic math formulae with no physics behind it. Notable exception is iRacing which has a physically based tyre model based.

But the physical phenomena going on in a deforming, elastic racing tyre are much more complex than a wing cutting through air.

The 800k hybrid buses and the 1.2M pure EV buses don't get 6mpg.

The average number of people you need for simply the fuel is like, 5. But as far as all other factors, a lot are fixed costs, so number of trips is more important that average people.

Not to forget, again, electric buses exist and work well.

Another part of living in a society is accepting that rules are blunt and broadly applied, and should not be complied with blindly. They may be broadly correct, but specifically may not be (or overly conservative).

The law is the law is not sufficient justification for really anything, except for an officer of the law, the court, or judge dredd.

You're probably trolling, but in case you're not aware, Waymo is the only company that offers a level-4 robotaxi service, albeit only available in a small region.
> The drivers would have known that when they showed up and she has a geared-up guide dog and she can't see. If a driver cancels the ride at this point, there is no ambiguity that they're just shitty people

but if the uber driver did not expect this, then aren't they getting a shitty deal if forced to accept the ride?

If the blind person had to specify ahead of time that they have a service dog, and let the drivers accept it knowing so, then there shouldn't have been any problems. And if there's no drivers willing to accept this condition, then obviously the price is too low - the price would have to be increased such that it is acceptable for a driver to take the risk/damage of a service animal to their vehicle.
All passively cooled thin highend phones can't run highly loaded games longer, due to GPU makes massive heat, so actually fan is practical for such use case.

Well,as a Kiwi, it's... complicated.

We did well when the "mother country" treated us and our exports as special. We pioneered frozen meat shipments as part of that. [1]

When the UK started treating us less favourably as it moved towards the EEC, (And because we were outcompeting the UK's own farmers), our economy was hit hard.

We had to pivot the entire structure of our economy, away from a government subsidised agricultural model (like the EU, UK, and US are still running) to a free market one in a manner rarely seen in so called free market countries - no tariffs, no subsidies.

It caused a lot of pain, bankruptcies, and suicides.

And once we no longer had preferential access to the UK market, we had to go out and find our own markets.

So while we initially succeeded because of colonialism, once the apron strings were cut to suit the needs of the colonial master, we succeeded in spite of colonialism.

> As we are building more infrastructure, we could endeavor to do it in ways that make it easier for cars to drive autonomously, with things like grade separated or other protected bike lanes, clearer signage, and other accommodations that will make things easier and safer for human and ML drivers.

At least in the US, my major concern would not really be building it right the first time (though there are plenty of places where we don't even do that), but maintaining it over time.

Many jurisdictions can barely keep the paint legible on the roads, so autonomous cars are just going to have to deal with poor or deferred maintenance.

Like most thing Sony the Hardware is good but the Software (and its support) is very crappy though. It looks flashy on the comparison table but falls short in real usage and support, and probably why with more exposure than LG (afaik) they seem to not catch on.

I've only ever owned 2 smartphones in my life: Samsung Note2 and my current Sony Xperia XZ. Until now I've never experienced the touch screen go broke after an Software update, and that the temperature limit of the camera set so weird that 10min continuous usage leads to a warning popup (that can be removed without hardware damange, if you root the phone).

Their lack of customer support is also not doing it any favour for getting respect.

The only public data is California's safety reports over the last couple years, which show Cruise and Waymo having millions of miles driven with Waymo having fewer "disengagements" than Cruise. There is also the fact that Waymo has ride sharing service in "production". As someone who is also outside the AV industry that is the closest I've gotten to a source, everything else is just hearsay by various Hacker News engineers about how Waymo is the best.

The ranking as I understand it is Waymo, Cruise, then everyone else.

You're right about that!

If I was to make a HN-friendly version, I'd probably make static JSON files that list all the numbers, indexed by the first four or so digits. When you enter a number, the first digits are sent to the server, and the appropriate JSON file is returned. That list is then searched client-side for the full number and the result displayed. The code should be simple and easy to verify that the full number doesn't leave the client, while maintaining the same simple user interface I already have. Variations of this idea could be more secure (i.e., only enter the start of the number and search for your number yourself in a long list) but less user-friendly.

I don't actually have any plans on implementing this though. I feel satisfied enough with what I have.

(I don't think hashing would work because the address space is too small and reversing is too easy. There aren't any email addresses.)
There are tools for discovery and they are better than ever. Think wilby.me and awesome-* lists.

But there is so much noise, so very very much noise and utter crap out there that it is terribly hard to find what we are looking for.

I sympathise with you, I used to be proud in my Google-fu, saying if I came across something on the internet, I can find it again, but that's just not true anymore. It's not finding needle in a haystack anymore, now its finding needle in Mount Craperest.

I built it, along with a long (long!) detour to build glslc, which AFAICT Debian does not package although it does package libglslang.a (!?).

The CMake find_program thing was utterly unable to find glslc, even when I placed it in /usr/bin/; I had to hand-edit the build/CMakeCache.txt entry. (^*%^&^$%&% CMake.)

When run, it pops up a window frame for a fractional second and dies with "VulkanInstance: no physical device". Otherwise, nice!
I may be in a minority here but that simple UI/UX design is the one of the main features that gravitate me towards stock android. I like the simplicity of that UI and all other themes look like chaos on my screen (that's just me). One point that I agree on is Google should definitely add useful features in their stock android. The sweet point is something like Oneplus's OxygenOS. It is close to stock android with added features and some UI tweaks (though they're going off that route lately). But, from UI perspective I think it is atleast top 2 for me (other one being OxygenOS).

You should at the very least investigate the effectiveness and risks of resuscitation. I only got a DNR after being diagnosed with incurable cancer, but had I known the (in)effectiveness and risks of resuscitation I would have done it much earlier.
Unfortunately for us, there is no such thing as free market. Deregulated markets devolve into might makes right (by size), regulated ones are facing the problem of justification for everything. In terms of wages, the markets in the US are extremely deregulated, in addition to lobbying messing with the politics. Somehow actual solutions are presented as less free market when they don't actually impact how trades are made.

Big corporations can always undercut small companies on costs by investing into capital expensive technologies. Does it mean the smaller companies should be allowed to run wage slavery? No, because then we run into arbitrary wage differentiation.

The proper way to evaluate the minimum wage is to compute local Purchasing Power Parity, check how many PPP-dollars are required for life, then set the minimum wage at slightly higher level to compensate for how rarely it is adjusted. These numbers will be a bit different per state in plain US dollars.

Anything else is not a living wage, and a living wage is the only reasonable way of approaching it.

From capitalist point of view, a business that cannot supply a minimum wage is insufficiently competitive and should fail. It is trying to run feudal by creating wage slaves.

Alternative approach would be interventions to lower PPP-adjusted cost of living, such as building cheap or free housing, not means tested food stamps, free healthcare, free education etc.
But these are much less predictable, and put the onus on government, while at the same time allowing bigger corporations to undercut their salaries, so it is at best a part of a combined approach.
I don’t, but I do work at a successful, profitable startup that has grown from 3 to 18 people, so I’ve seen how these things work to some extent. My parents also ran a small business that had a trademark dispute with a large fmcg company, so know how companies will protect their brands (and that it is possible to reach a compromise which protects both businesses interests). I also have some small side-hobby projects that are minorly profitable but also don’t have any overheads (so profit isn’t hard!).

I’ve not seen anyone else have to give their credentials though. Do you only need credentials for people you disagree with?

Wait, why not? The definiton of separate infrastructure seems arbitrary. GPS relies on satellites. Is that separate infrastructure?

Humans use road signs and lights and... We created separate, additional infrastructure for ourselves as drivers. Why wouldn't we add infra to "help" autonomous cars? Can't a car that senses RFIDs at every corner be considered autonomous, full self-driving? How is that different from sensing road markings via camera?

If the issue is just a terminology one, to distinguish "full self driving" versus "full self driving with fully self-contained reasoning" or whatever I must object - that's not how these terms get defined.

Tesla is arguably misusing the term "full" because it doesn't operate to the level we'd expect; not because of whatever resources it uses to function

If this is too long -

tl;dr: I think the absolute majority of people won't mind calling a car that requires _any_ additional infrastructure (including communication with other cars) a "full self-driving" car. As long as it drives itself 100% of the time without a human driver, it's full self driving.

Wouldn't the signal travel time of energy pollution be the speed of light? Certainly faster than the speed of sound, but still geological timescales.
Owning a car means you get the exact 2 hours you need rather than waiting for the 2 hours a taxi company will sell you. It means you can use the car as 24 hour storage for all the things you keep in your car. It means sometimes you can use the car for way more than 2 hours in a day. You can share the car with other people at minimal additional cost. It means you can live in a rural place 2 hours from the nearest taxi company and not have to pay for 2 hours of additional time as the empty taxi comes to you and 2 hours more when it returns after you're done with it.

For many people a robot taxi is a viable alternative to car ownership, but for plenty of people owning a car is always going to be a better option.
>>Deregulated markets devolve into might makes right (by size), regulated ones are facing the problem of justification for everything.

The existence of regulatory restrictions on free market exchange, that distort the free market, will rarely justify further regulatory infringements on contract rights, like the minimum wage. The additional regulatory restriction will generally add to, and not counter-act, the existing market distortions.

>>The proper way to evaluate the minimum wage is to compute local Purchasing Power Parity, check how many PPP-dollars are required for life, then set the minimum wage at slightly higher level to compensate for how rarely it is adjusted. These numbers will be a bit different per state in plain US dollars.

That in no way determines if a price floor of labor will do harm to public welfare and the economy.

>>From capitalist point of view, a business that cannot supply a minimum wage is insufficiently competitive and should fail.

That is not a "capitalist point of view". It's just a pure economic fallacy that harms all those who are priced out of work, and capital that is less efficiently utilized as a result.

I recommend you read the Wikipedia article on price floors:

https://en.wikipedia.org/wiki/Price_floor

And then consider how a price floor would affect available labor.

Agreed. I have incurable cancer and I very much plan to die pleasantly. The cost of that is that I will probably die much sooner than necessary, but I can live with that.
I'd recommend signing up for a guest account at https://www.valueinvestorsclub.com/, where the likes of Michael Burry and other famous professional investors have posted (see Mike's posts here: https://valueinvestorsclub.com/member/michael99/1219). Mike makes it look easy in some of his posts, but there was no doubt a great deal of analysis and thinking involved. The reason I suggest this is to get some sense of what can be involved in selecting individual securities to invest in. If you're still considering a style involving picking a handful of stocks, go and read some CFA level II CBOK material on equity valuation, and consider whether it makes sense for you to try it as an individual investor. This would be very time consuming, but consider the time invested into earning the funds in the first place - if you really think you're skilled enough to choose a concentrated portfolio, you owe it yourself to invest some time into becoming familiar with common methods of analysis, and to think about what edge you have VS the seller of shares when you purchase them.

The point of doing this is mostly to dispel the extremely common Dunning-Kruger effect among amateur investors. Maybe my advice will be unsatisfying for you, but there is no single right answer to how one should invest. Reading a bit about how to think about valuation, risk adjusted returns etc.[0] should help you form some opinion on an investment strategy that you will feel most comfortable with, which will be important for you to keep in mind when facing the vicissitudes of the market.

On a global level,

1. LG are crap at discovery ( Sales and Marketing ) and distribution. Something which despite HN is a forum from VC and Startup, pays very little attention to.

2. LG's phone QA were never really as good. This has been the case since pre-Smartphone era.

3. LG WOLED, something they tried to get it work on Smartphone but never worked and their AMOLED panel were inferior, which sort of have a knock on effect on their brand.

4. They were just never as aggressive as Samsung, I dont mean Samsung Electronics and LG electronics, I mean the whole Samsung vs LG. I guess someone from Korea can chime in on that because I know LG is competitive in South Korea.

5. Samsung are great at making Smartphone. Their whole Business Model. If you think you know Flywheel because you know Amazon. Take a look at Samsung.

6. On a Hardware level, Samsung is way ahead of LG on Spec. Which is what nerds and Tech reviewers likes to focus on. UI and Software tends be subjective. And stock Android is like the year of Linux on Desktop.

7. You would have thought they could built some synergy with LG OLED from TV. Nope.

>>So trust the 101-level dogma

It's not dogma. It's a very strongly supported economic principle. In the absence of definitive proof either way, we ought to trust well-tested and supported economic principles.

Price controls == bad

>>it's also quite clear that actual economic and sociological systems are far more complicated than its models?

This is a strawman. Economists are fully aware of the imprecision of predictions made based on theories relating to generalizations and simplifications of the economy, and also that this doesn't change the fact that these theories do a good job of approximating the effects of government interevention on real world economies, and that it is far better to legislate in accordance with them than in conflict with them.

The idea that some cookie-cutter price floor, recklessly imposed on a diverse landscape of economic actors, based on utopianist left-wing drivel pushed to the public by rent-seeking labor unions and left-wing demagogues, is going to do more good than harm, is very very misguided.

HN Community.

I am a part of a lot of professional communities that are hosted on slack, discord, whatsapp and telegram.

These could be entrepreneur communities or vertical communities like product, design, engineering, angel investing etc.

The problem is these platforms weren't built for professional networking.

To network, it's important to automatically answer the question "What do you do".

If I know your company, and your designation, I can network with you

So we set about building a SAAS platform that helps you launch a private linked-like professional network.

Please do take a look and play around.

You can launch your own professional network on http://www.unsolved.network

Or join a demo community by visiting

http://avengers.unsolved.network

I am sorry, it does require you to signup with an email and password and I understand that is friction.

But I hope some of you will take a look and tell me what you think both about the product and the business opportunity
