> I don't get what you mean by "ensure good execution" because it takes so little for grocers to successfully move into a market like Blue Apron's.

It also took little more than a good website to compete with Amazon in the early days, but B&N/Borders/etc. never figured out a way to do it well.

What I want to do is order stuff with as little friction as possible, and have the right items delivered in a way that's convenient.

The chain delivery service we tried involved a few things:

1. A poor site experience. It had 'pantry' functionality, but it was anything but good. Putting together a large order took nearly as much time as doing it in person.

2. Delivery was scheduled during windows, windows that were often either missed, or perhaps worse, beat by many hours. They were often many hours outside the window. We eventually stopped including anything fresh in the order and would pick those up ourselves on days when we were hosting guests. That defeats much of the point.

It was like ordering groceries from the cable company.

3. We were able to select whether we'd want substitutions if something was unavailable. In virtually every order, we would either receive items (we didn't want) when we specified no substitutions, or didn't get substitutions when we wanted them. Often the substituted items were poorly chosen as stand-ins for what was unavailable.

4. It required a young male delivery guy to enter the home to deliver the items to the kitchen. It was a different person nearly every time. This is unacceptable for a number of reasons. Whenever substitution issues happened they seemed so disconnected from the process that it meant it never got better, and recourse took more time than it was worth.

Why a company with billions at its disposal and half a million employees can't get that right is somehow both a mystery, yet also a foregone conclusion.

While I seriously doubt Blue Apron poses much of a threat to the entrenched companies, I think someone else (perhaps Amazon) probably does.
Almost no one? Obvious anecdote alert, but I don't know a single person who shops on Amazon who hasn't made the exact same observation. Many/most big ticket items are, for most people, a once-every-X-years purchase, and yet Amazon's recommendation system can be counted upon to suggest another TV, another DSLR...it's remarkably terrible for a system that's been under active development for twenty years.
I'm thinking more about travelers passing through. Even if I owned a Tesla I literally couldn't take it to see my relatives in rural North Carolina, or go camping in many locations. Right now supercharger station coverage is about as effective as cell service was 10 years ago. It's there, but there are noticeable dead zones that lots of people (although perhaps not people in the HN bubble) will care about. Hopefully Tesla can continue making money and build out the infrastructure further, but right now for anyone on a strict budget, even a Model 3 is paying a large premium for an ultimately less capable vehicle. At their current rate of expansion, maybe in 5 years I'll start thinking about an upgrade. :)

I think the smart money should be looking at which established car-maker will be best able to make the transition to a future with electric personal vehicles and autonomous cars. It's clear there's going to be some kind of disruption in the next several years, and new players and the survivors are going to be splitting up the bounty.
Why do people compare Telsa to companies like Ford and GM? Genuinely curious because I see it a lot. Both those companies sold over 1.2 million cars last year. Tesla around 16K. Numbers are US only.[1]

You lost me with that quote.
I mean, I don't think that is what is happening right now, but you might be surprised what it takes to move a market sometimes. The Flash Crash[1] was caused by a single individual. Granted he was playing with futures and you can get some insane leverage with a modest account there, but it is within the ability of a couple of individuals with six-figure accounts to make some well placed bets and move a market significantly.

Why are you assuming that I'm a man? Either way, these kinds of programs are useful for certain people and there are lots of other articles in defense of them. Just because one person didn't want to participate doesn't mean that other people aren't happy that they exist.
And the engineering?
I have a pretty big app that uses Sheets for free storage, apps script for processing and HtmlService to expose an json api endpoints and to serve the UI. I'm pretty happy with it. Totally free app.

I don't consider rest for optimal work "idleness", in fact that's a big part of productive work. I think there's a huge difference between getting a full 8 hours of sleep and what the author is suggesting in the article, but maybe that's just me.
How much faith do you have in the statement that the flash crash was actually caused by a single individual?

Which brings this full circle: a state of lowgrade permanent fear is created and maintained through jingoistic propaganda in order to control the populace and keep the money flowing with minimal dissent. Since the US doesn't face an existential terrorism threat (compared even to the 70s), the idea of a few have been created -- and are just remote enough that people will be afraid but not ask questions.

Jeez reading that over I sound like a conspiracy theorist. But it in fact is straight out of the playbook.
Just a tip to make that syntax a bit less ugly[0] Using babel / typescript

`a.b = c` becomes `Object.assign({}, a, { b = c })`

can be written as

`{...a, b: c}`

(this desugars in typescript to)
`Object.assign({}, a, { b: c });` [1]
(note also you had a minor typo there with equal sign {b=c} should be a colon, I feel like I make that mistake multiple times per day when writing typescript / javascript, having two different assignment operator characters in the language is not good imho. i'd prefer if it was all just `=`, that will never change at this point though. )

For your seconds example,

`store.dispatch({type: METHOD, data})`

perhaps the Proxy object[2] (which allows for delegation, method_missing like functionality) could be used to turn the calls back into store.method(data)

That's one point of Blue Apron. For me, the point is that I can spend 100% of my cooking time cooking, instead of planning or shopping. As a result, I cook a lot more, and I like that.
None that we found good enough to stick with, unfortunately. The market still feels wide open.

Reminds me of Netflix recommendations. They keep recommending I "continue watching" the ~45 seconds of credits I missed from the last dozen shows I watched. Most lists have movies/shows I've already seen at the top still.

I'm sure there's some reason behind it all, whether technological, user behavior, or obscuring a small catalog. I wish I knew what it was.
Agreed on specialization being valuable, but the issue that arises is when this type of UX/Product process isn’t in place the specialists tend to spin out of control and lose sight of the users. And likewise, the UX team really, really needs those architects on their team to both help ship the experiments/improvements and make sure they aren’t proposing features that aren’t technically feasible with a given budget/timeline/tech stack.

Some of the best ‘UX’ solutions I’ve ever heard in meetings came from the software architect, usually along the lines of “Ohhhh, THAT is what the customer is trying to do? We can repurpose the flux modules pretty easily and ship that in a week or two!”.

Without good software architects on the UX team, designers will often punt on some of their more creative ideas because they assume it won’t be possible. A great architect tends to battle boredom, so the push/pull with designers can often keep them engaged and challenged. Win-win!

Do you think that referring to "absurd cost" is going to result in a good discussion?
Here's a link to the earlier post, which was (unfairly IMHO) flagged despite the direct relevance to HN and a largely civil discussion in the comments:

https://news.ycombinator.com/item?id=14703661
I'm sorry but that's just flat out wrong. Just last year Mercedes advertised their blatently inferior (compared to Tesla's AP1 at the time) driving-assist features as literally "Self-driving" and saw NONE of the backlash that Tesla faced with the autopilot accident. And Tesla has never advertised their current or former Autopilot as being "Self-driving".

I think the opposite is happening - that Tesla is under much more scrutiny because they're the new one on the block. Because the established automakers have done some terrible shit, which would absolutely kill Tesla as a company.

I'll gladly find sources and further elaborate, if you're interested.

You've entirely missed the point of my post, it makes no difference if the tools are built in or how quick they are to activate. Have you personally actually tried turning these tools on and testing your app?

My point is that I believe that all the people claiming it's easy are only doing the 'best practise' implementation (which I agree, is easy and doesn't add much time) but without actually testing that it all works smoothly they haven't finished and are just part of the problem.

My point is that from my direct personal experience with similar tools, it does not take 5 minutes. It takes weeks of additional testing and bug fixes to get a large app working smoothly with accessibility tools, after you've followed the best practise for the initial implementation.
I can't help but feel cryptocurrency is a fad. The technology seems sound but the economic policy isn't. There's a reason we don't use the gold standard.

Fiscal policy is an important tool and I just don't see a future where the world's nations give that up.
I've been invested in TSLA since 2012. And there's always been people saying it's "over-valued", especially the media or folks who don't believe in Tesla's mission or potential. The best thing I've found is to work the numbers a few years out and see what you come up with. Sure, each person's forecasts will be different, but I base my numbers off of company forecasts and also Tesla's track record.

2020 deliveries: 1M vehicles (according to company guidance)
Average sale price per vehicle: 900k Model 3 and Model Y x ASP $42k = $37.8B. Plus 110k Model S/X x ASP $90k = $10B. Total revenue $47.8B

Gross margin = 25% (company guidance is 30%+ for Model S/X and "mid-20s" for Model 3/Y).

Gross profit = $12B

Operating expenses = $6B (note: It's difficult to predict operating expenses 3 years out, but Tesla will likely experience a lot of operating leverage as their sales will grow much faster than R&D and sales.)

EBITDA: $6B

P/E multiple: 30 (note: If targets are achieved in 2020, Tesla likely to be growing 50% year in revenue and would likely fetch a 30-40 P/E multiple.)

Market cap: $180B

# shares outstanding: 185M shares (currently 164M outstanding)

2020 stock price = $972

A few comments:

1. The above are my forecasts based on my beliefs that Tesla can reach their own forecasts of # vehicles delivered in 2020 and gross margins.

2. Each person has their own beliefs/ideas of Tesla. So, I'm not trying to convince anyone.

3. This model can be tweaked based on changes in # vehicles delivered, gross margin, or operating expenses... to name a few factors. So, it's not perfect but it gives the basics.

4. If you find someone bearish on TSLA and who thinks it's "overvalued", ask them to give you numbers like I have. Chances are they won't be able to.

5. The Model 3 will be the iPhone moment for autos. A sexy car that redefines transport and brings in high margins. This is why Tesla has potential to be the most valuable company in the world by 2025.

6. Tesla's moat grows as they execute faster than any other auto company. It's not appropriate to value TSLA based on other auto makers. It's like valuing AAPL in 2007 based off of Nokia and Blackberry.
Sure, there are many infrastructure products that are different from cities versus rural areas. Tractor maunfactures do awful business in cities, but John Deere is still sucessful.

Cities are still half the population.
Ah ok. So the execution you're speaking of is on the delivery aspect. That makes sense now. In terms of execution, I was thinking you meant purely of the food itself and leveraging the existing dominant consumer behavior (going to the grocery store)
The analyst in question, David Tamberrino, ranks 10,337 out of 10,667 on TipRanks, meaning he is one of the worst analysts and has been wrong all the time. Link: https://www.tipranks.com/analysts/david-tamberrino

Those who keep repeating that Tesla stock is "overvalued" should understand that a stock's "value" is based on the current value of all future cash flows. Ford and basically all the other incumbent car companies are generating profits now, but are stagnant and waiting to be disrupted. Meanwhile Tesla's revenue is $7B last year, will be $10B+ this year, $20B+ next year, and $60B in 2020. Which companies are overvalued and which would you rather own?

There's a reason Wal-Mart's top and bottom lines are both several times that of Amazon, yet Amazon is now worth twice as much as Wal-Mart. It's about growth and future addressable market.
Well put. I've seen the 'DAO-hard-fork' line swung around pretty wildly over the recent popularity surge the past few months -- but you nailed it.

That difference is the whole point. It could be argued that Vitalik has enough political clout in the community now to do nearly whatever he wants, but that only goes so far as whatever he's proposing is agreeable upon a consensus.

If the miners disagree, then it's a no go because they make it work. If the larger userbase disagrees, then the miners will be bent to disagree because there won't be any money in it if everyone sells off. It's shortsighted to think that because there are influential parties the whole system is broken. (hint: functioning democracies work this way. As far as most people can tell so far, it's a good thing)

I also agree with the rest of your positions here. To wit: while governments are hesitant and slow to get directly involved, they _are_ doing active research[0][1] into how/why/when it will be valuable to use existing blockchains or for what reason they could employ new ones. So are many banks. The distributed ledger seems to hold inherent value for everybody.

But if "how Tesla will actually perform" in the future is already priced in today, the stock can't continue to go up unless it continues to be overpriced.
Agreed. This is a very sensible answer. It boggles my mind that instead of ah "Other" field, they added a "Transgender" option.
I wonder if the person in question had his problems before January.
There are several services that cater solely to vegetarians, which is one of the problems for Blue Apron -- too easy to replicate.
Men-only clubs were broadly a problem because (at the time they were prevalent) men and their clubs held a significant portion of the money and power in society. Exclusion was an extreme sanction.

You don't have to be excited about this but if enough people are you'll just have to follow.

In terms of mass adoption, with regard to Skype, is what I imagine he meant. Anyway, it was certainly true for me. I had to make a lot of calls to less developed parts of the world then, and it worked reasonably well.
I had a similar thought as I typed - having more than one or two deep-fried dishes a week is unappealing, and having too many deep-fried courses together is unappealing (at least to me). And then potential health issues. When I get home, and after eating my fried won-tons, I'll check out the link.
Typical argument on the Internet:

I don't really understand your rationale. You reply to someone who is refuting a point related to cannabis legalization. I'm not interested in following this argument to whatever winding road you're attempting to steer it to.

I don't like secondhand smoke, and studies are clear about its harmfulness. Nobody in this entire thread is advocating burning carcinogens indoors.

The effective mitigations (not sure why you used scare quotes) are

1. Burning carcinogens outside

2. Accomplishing the goal without burning carcinogens, e.g. ingesting chemicals through oral consumption or vaporization.

GM is invested in Lyft and Mercedes Benz has their Car2go division. Seems to me that the traditional car companies have a reasonable head start into the autonomous "transporation as service" area as Tesla does, just from another direction first.
He definitely set off a chain of events that caused automated market makers to re-evaluate their idea of a fair market value rapidly in the downward direction, and it cascaded from there.
MobX (in strict mode) forces you to annotate your mutations (via the @action decorator).

MobX is useful mostly as the data model / selector part of redux. It does an awesome job of it. Once you've defined your core data model, you can create layers of computed properties and transformations out to your view. The view then rerenders in a really optimal way.

Where redux shines is the prescriptive nature. The layout of a redux app is fairly well defined at this stage and there are "right" and "wrong" places to put (and look for) different types of code.

With MobX there's still no clear way to layout your application, so, as you say, you need to be more disciplined with your approach.
> It also took little more than a good website to compete with Amazon in the early days, but B&N/Borders/etc. never figured out a way to do it well.

Borders didn't try in the early days; when they got around to online retail, they outsourced it to Amazon. Much too late they tried their own...

B&N actually had a good website (it was always better than Amazon's for ordering books, IMO), they just weren't committed to competing with their own stores on price because the website was an "and, also..." not a bet-the-compaby deal.
It seems like we're all saying the same things - I agree it is likely that someone who has bought a vacuum before is more likely to buy another. But to make the recommendations really shine, it should wait n months before suggesting that again, where n will vary quite a lot by product type - those are the sort of exceptions I'm talking about.
The implementation in the blog post does handle exhaustiveness via the "default" case of the switch statement.

> First, we don't need more mining, we need much less, preferably zero.

I don't disagree. We will have some mining forever though, whether that's here on earth or elsewhere.

> We should be living more sustainably, with less consumption per person.

I hope I didn't give you the impression that I think the opposite of that. I am all for sustainability. Including population sustainability.

> As to wealthy people having children, that's a non-sequitur: wealthy people are such a small portion of the population that even if they all had 6 kids, it wouldn't make a detectable difference. It's the middle class that you want having kids.

? I want fewer kids and fewer people. I want those with the means to (rich or upper middle class) to have kids, at least until we get the population of the planet much lower. So yes, a small amount of people having a few kids isn't a non-sequitur at all.

Dude/dude-ette... you should read my posts! I'm all for that :)

Thanks for your perspective.
Yeah I think it might be easier for the traditional car companies to slide into making electrics than people think.

I could easily imagine the traditional car companies making the exact same successful models as now, but with the electric engine being a checkbox option.

The 2017 Electric Volkswagen Golf is apparently quite good.
