Exactly. I work in automotive and it's important to understand why traditional automakers have dealers and why Tesla doesn't.

The first mass market Tesla (Model S) came to market in post app store world. By that I mean, not only is it possible but it's obvious that vehicles can and should be diagnosed and firmware should be updated over the air. The only reason they were able to throw away the dealer model is because they could collect analytics, perform diagnostics and firmware flashes over the air. Without this advancement, Tesla would need significantly more physical presence akin to dealerships (and in fact, they kind of are building a light showroom/repair network as they grow so the dealer model isn't all that crazy in some respects).

Traditional automakers have been around since before OTA was possible or practical or anyone had even thought of it, so dealers were at least necessary at one point in time to perform these tasks. Now that it is possible, and many new vehicles even have wireless internet, very few traditional automakers actually perform remote diagnostics and even fewer update more than a couple ECUs (Electronic Control Units) over the air.

There are a number of reasons for and against this, but at the end of the day they were forced into a situation where they needed dealers and for that reason they also have the luxury of offloading many of these tasks onto the dealers. This luxury is actually very important because a major OEM has hundreds of models of vehicles that they need to support. Tesla obviously has far fewer so they can afford to take on some of those diagnostic tasks and of course they have to because they don't have franchises with technicians in them.

As for success, I believe Tesla is very successful for a variety of reasons (too many to list, but I'll mention some of the major ones):

1. They care about design. They're not the flashiest or most radical designs, but the designs are very thoughtful, tasteful, elegant and minimalistic -- all of these are qualities that are fashionable at the moment.

2. The cars are technology first... they come with a lot of useful technology that people want because it seems obvious to have these things in contemporary cars. Most other vehicles in the Model 3 price range are technology last -- the technology that seems obvious is a paid upgrade.

3. They are optimistic and progressive. Even when someone knows that some model 3s are built outside in a tent and there are mounting quality and repairability concerns, they don't care because they want to support the flier that just might make a difference in the world.

Why does grandma need to differentiate? All the news she reads about Coronavirus, COVID-19, corona, 2019-nCov, etc are all about the same thing. And searching on any of those term will take her to the information she's looking for.

If you're interested in reducing confusion, why are you adding one more name "Wuhan flu" that's not even accurate, a coronavirus infection is not a flu.

> Some would argue that as long as you are able to communicate effectively, your grammar is not wrong.

Sure, but this is sort of begging the question. Bad grammar can subtly affect the effectiveness of communication in ways that sometimes aren't even explicitly clear to the participants. Grammatical rules don't exist (solely) because someone decided to be stuck up for no reason.

> Another critique might simply be that while it is certainly useful to understand rules of grammar, it isn't worth derailing a conversation over.

Sure, this roughly describes why I don't correct strangers in practice. But note that the "derailment" is just another side effect of the insecurity I describe, not an inherent quality of correcting grammar: when someone corrects my grammar, spelling, or diction, my reaction is "Thanks! <rest of comment back on topic>". I don't see how this is derailing at all.

> When I WFH I just slack off.

I've worked in an office for years, and then transitioned to working from home for years. The initial transition was rough: snacking, lack of motivation, lack of structure.

But it only took about a month to get past that. You start building your own routine and structure, optimized to your life, not a mandated 9-5. Not only am I more efficient and less stressed at home, I'm pretty certain I actually "work" more hours than sitting at an office.

And I'm a pretty extroverted person, that thrives with other human contact. When working from home, I get to choose when to socialize/collaborate, it isn't hoisted on me.
Can you back this claim up with a peer-reviewed study? (i.e. not a C|NET article, and not a link to the totally discredited CDC)
Christian Drosten, who's likely the origin of these numbers, has explained them a few days ago in a podcast.

The math is incredibly simple. The idea is that right now you have an estimated transmission rate of 3 people infected by one person. (Of course this number has high uncertainties and can be changed by better isolating patients, but let's assume it's roughly correct.) If you want to stop the transmission this needs to go below one. The major thing that can stop transmission is immunity from patients that already had the disease (assuming, which is probably true, that most patients won't get infected twice, even though it may happen in rare cases).

So getting from 3 to 1 means 2/3 of the population need to be immune.

This is a nice article, and gently (with great explanation) introduces:

• The idea of approximating a real number by rational numbers (e.g. √2 ≈ 99/70),

• Dirichlet's approximation theorem, that every real number x has a rational approximation p/q such that |qx - p| < 1/(N+1) using a denominator q ≤ N, for any integer N,

• The Duffin–Schaeffer conjecture, recently announced to be proved.

BTW, I got the above "√2 ≈ 99/70" (≈ 1.4142857…, better than 1414/1000 which has a much larger denominator) from a webpage I made a while ago, to generate the best rational approximations (with increasing denominators) for any number: https://shreevatsa.net/fraction/best (Of course the continued fraction for √2 has a very simple form so convergents could be written down by hand.)

They even say it themselves: "Furthermore, we should bear in mind that this is an experimental study, with relatively small numbers of volunteers, which limits the generalisability of some of our findings."
Would it make sense to do controlled infections of younger medical staff to build immunity against the disease so they can do their jobs when masks and gloves become scarce? Ethics aside just from a pure optimal outcome perspective. Italy is already reporting a shortage of masks.

Actual militias living out in the woods are among the least likely to become infected (and thus quarantined).

The implication of the above comment is "low rent chum will die (good) but establishment channels like newspapers will also die (bad)". I'm saying that the decentralized "low rent" stuff is the value of the Internet imo, not providing another medium for channels that already exist.
> Effective immediately, people in Sacramento County should not quarantine themselves if they've been exposed to the COVID-19. Instead, they should go into isolation only if they begin to show symptoms of the respiratory virus, the county's health department says.

> Sacramento County has at least 10 coronavirus cases, including one person who recovered.

10 cases and they already gave up on quarantines? The decision maker either knows more about unpublished cases or don’t understand infectious diseases at all... What a great way to make sure more people “show symptoms” two weeks down the road.
Mitigation is not a binary thing. If a temperature sensor is somewhat inaccurate, but can still identify outliers (even with false positives, or even false negatives), there's value to it.

If consent matters, then Google implicitly received it from Sun, but had it removed afterwards by Oracle. So if you actually support Oracle here, I don't understand how you can say "consent matters". The consent was given, yet you yourself don't consider it in Google's favor.
Thanks for posting that site. I hadn't seen it before. Comparing Italy and the US we appear to be roughly 9-12 days behind Italy depending on which specific metrics you look at like total cases, total death, new cases, or new deaths.

Nice to listen to a highly educated individual talk about their thoughts on this virus. A little too much Lyme disease. Overview: expect to live in this sort of environment for between 3 to 6 months. Vaccine is years away. Kids are carriers with no symptoms. Transmits via sharing air. Viral load is high prior to showing symptoms. Get lots of sleep, to keep immune system strong.
I don’t see anything about a 15% mortality rate. Can you point to that specifically?

We got similar news at Cornell today, with professors being advised to go online asap but will be forced to in early April which is also when students will be sent home. The problem here is that most upperclassmen live off-campus and can't be forced to disperse. Furthermore, many students are from NYC where they'll visit during spring break and then come back to Ithaca. The atmosphere on campus is very nonchalant; most are more upset by cancelled events than the possibility of encountering the virus.

I was going to attend Tensorflow Dev Summit. We dropped $350 on flights + airbnb for this week. But even after Google canceled the summit, it was still tempting to fly out anyway and go enjoy a week in Sunnyvale.

Thank you to Google for making tough decisions early, like canceling the summit.

Flu seasons are usually judged by what is happening in the other hemisphere. During our summer Australia had a bad flu season which corresponded to the US having a bad flu season during our winter months.

https://en.wikipedia.org/wiki/Flu_season
It looks that way because it's almost certainly been circulating in the US since January [1], and testing was hardly available until recently (and is still ramping).

Despite the long, largely unchecked circulation period, there's no hospitalization crisis here.

> Delimited formats are, in general, slower to parse than formats where the record sizes are encoded in the message.

I don't see your point at all. The state machine required to parse a JSON string essentially has only 2 states: current token is either a string character or a string delimiter. That's it. Adding a record size increases the number of states because now you not only need to track if a token is a string character but also if the character makes sense to be there within that state.

Moreover, when you parse a JSON string, once you hit the string's end delimiter you already are able to calculate the string size. Thus, if the string is short enough to fit the buffer then not only is the lexer simpler but it also requires the same memory allocations than strig formats with record sizes. If however a string doesn't fit the buffer then we are already in the territory of a ropes data structure in both cases, thus the number of memory allocations tend to be equivalent.
> I can tell you that those statistics will probably be absurdly horrifying.

Absolutely. I know a guy who runs a few dealerships and they don't even sell cheap cars yet they buy tons of leads each month for people with bad credit who want new cars. The leads cost $50-$150/each depending on how bad their credit is. So you know that those buyers are still buying brand new cars or they wouldn't keep buying these leads. Sure, there are people with bad credit who can afford these cars, but extenuating circumstances are not the majority.

I know it's another anecdote, but from spending a lot of time on car forums, I can't count the number of discussions I've seen around what kind of car people think they can afford. There are people making $35k/yr buying $80k pickup trucks. I don't even know how that's mathematically possible unless they still live with their parents.

Car loans are absolutely horrifying.

Even CNN which has been publishing “masks useless” articles every day for like at least two weeks published a piece a few days ago saying that while wearing masks may not be effective in the U.S., it could be effective in high population density countries with busy public transit (can’t find the link now). I’d say the crowded airport security lanes are definitely among the places where masks are warranted, even in the U.S.

Most cars are ugly these days; Tesla is not an exception. Cars used to be beautiful and peak car design was in the 1950's and 1960's. I find it interesting that people are retrofitting a lot of old cars from that era with electric; looks like a lot of fun to drive in those things.

I'd love to see some old designs from that era reproduced with electric. I'm not talking about monstrosities like BMWs mini (anything but mini) or VWs attempt to revive the beetle. They basically lost the essence of both designs and turned them into pompous monstrosities with a lot of plastic, leds, and ugly loud colors. The current mini especially is offensive to me compared to the original. Completely misses the point of the original in every possible way.

For the North American market; what about some old school muscle cars, Cadillacs, etc. Those were awesome design classics. Their modern descendants are not even worth mentioning. It's not like a modern SUV is in any way efficient or practical. With EVs, aerodynamics matter a lot less because the fuel (i.e. electricity) is cheap.

But it seems like designers these days insist on rubbing out all the little details in the original that made them so nice.

so even if you have a great computer at home, you'll be working from your laptop. Many of us at the kitchen table. U... Think you'll just go buy a nice monitor from Best Buy and dock it with your laptop?

You have a great computer at home, but it has no monitor and you use it from the kitchen table? I have a "decent" computer at home, and I plug my work laptop into the monitor when I work from home.

You weren't the first to think that; computer monitors are sold out across the city (having 4 giant tech companies all go 100% WFH at the same time will do that).

You'd think that living and working in the Seattle area that you'd have heard of a little online retailer based in Seattle called Amazon. They can deliver a name-brand 27" 1920x1080 monitor to you tomorrow for less than $150. Want a nice 32 inch wide screen 3840x2160 like you ahve at work? That's closer to $350 but you can still have it tomorrow. I see lots of monitors in stock there (as well as on Newegg and bhphotovideo, my other go-to online merchants).

If I didn't already have a good monitor at home and desk to put it on, I'd just buy a cheap $99 27" monitor and set it up on the kitchen table during the day, then if I no longer needed it after the office re-opened, I'd donate it somewhere.

At my company, WFH hasn't been an issue so far -- we have multiple offices and everyone was already used to using Slack and video conference meetings. To be honest, it's even easier to hold a meeting now since no one needs to find a conference room (they are always in short supply). But everyone uses a laptop as their primary computer, if they need something more powerful, they use a cloud VM.
> the so-called "autopilot" isn't actually meant to be used like what autopilot means to most people.

Given that autopilot for cars doesn't and never has existed it is likely that it means different things to different people.

That article was full of equivocations and misdirection, with CDC Director Nancy Messonnier wriggling out of any leadership on establishing federal guidelines for containment and mitigation and hapless (?) Dr. Peter Beilenson, head of Sacramento County's Department of Health Services, rhetorically throwing up his arms and embracing mitigation because Sacramento County failed to track infections.

All the while, the author of the piece is clearly trying to convince the reader that mitigation (which in Sacramento County means “self-quarantine only in cases showing symptoms”) is adequate if not superior to containment.
The purpose is actually so that nobody can make Mickey Mouse merch. Everything else is obfuscation.
