Good. When Tesla stock goes under $200/share, its basically an opportunity for free money.

Take a look at the long term chart for TSLA (5+ year). The stock dips below 200 (often right around 180), then within 6 months its back over 250.

Nothing to do with fundamentals, Tesla's true valuation, or technical analysis. If you have working eyeballs you can see it.

If TSLA gets to 180 (which I doubt), buy some stock, make 25-50%, and thank me later.
Remains to be seen. I can't imagine not wanting to own my own car. It's an extension of personal space for me. And I don't really want anyone else using it either.

Maybe younger generations will feel differently.
i am invested in Tesla because i feel like they have the best chance of seizing the bulk of the autonomous car market, out of the publicly traded companies available to me.

I could be totally wrong, but being first will allow them to grab the lions share of the business opportunities, and let them vertically integrate aka Tesla run uber, Fedex etc.. Being second is like being second with PageRank.
> These companies are going to get absolutely destroyed when the big supermarkets come on tap.

While I agree they're in trouble, i really don't think it'll be supermarkets that hurt them. Supermarkets are about as likely to rise up as Blackberry is about to destroy Apple.
I think the connection is the overuse/desire to apply deep-frying/machine learning constantly and to everything. While there are certainly (delicious) benefits, there are also drawbacks that make the non-stop use a net loss.

I used them for a few months, but then just got tired of the meal cycle and didn't want to waste any of the food I didn't feel like cooking. I totally agree that they really need to do more to prevent the monotony of the weekly meal box schedule. I also really wanted them to add desserts to their boxes, but they added wine instead... I don't drink wine so that did nothing for me. I also always had anxiety that I would have to contact customer service if any of the food didn't arrive in editable condition. They always backed up their product, but I don't like feeling like I have to be a part of their quality assurance team every time I open one of their boxes.
Yep, absolutely true.

Preethi Kasireddy did a fantastic presentation at ReactConf comparing Redux and MobX [0], Robin Wieruch wrote a good article comparing them last year [1], there was a Reddit thread with good discussion as well [2], and I have links to more comparisons at [3].

They're different tools taking very different approaches to solving the same kinds of problems, and they definitely appeal to different developers.

Sorry, I was referring to how it was obvious to so many that Barnes & Noble and Borders would crush this fledgling website founded by the kook who set out in a van to compete with them.

There are two reasons I like Blue Apron:

1) Here and there they have recipes involving ingredients not easily found in local stores
2) They deliver it to me

If I have to go to the store anyways, and presumably using ingredients they have there already, it has no value to me.
> While I don't disagree, people said the same thing about Amazon.

The difference to me is that Amazon competed aggressively on price and selection. You could get books or items which you just couldn't get in a local Borders. You could also get the same item significantly cheaper than a Borders or Barnes and Noble.

Blue Aprons value lies in the recipe and the convenience of having all the ingredients picked out for you, but charges a significant premium. I would like this as a way to try new recipes or expand my range (e.g. I don't stock ingredients/spices etc at home for Chinese food), but not as my go-to option for daily meals.

It may not be as easy for someone like whole-foods or Safeway to generate recipes, efficiently package/put-together ingredients etc, but I also feel the value addition is much less than someone like Amazon's was: More items and much cheaper.
Ah, OP's assertion was the price is crazy from retail investors, which i assume would be non-institutional, non-insiders. It's impressive that a few % of owners can double the share price. Unless, they meant Musk was buying shares at $350+
I just created a new account a couple of hours ago,

Presumably, if a mod thinks you're sockpuppeting, they just ban the account.

Anyway, the only way for us to judge the validity of your claim that you put non-trivial information in them and didn't use aggressive language is to... read the comments you made. But you can't show us the comments, since you didn't want to link them to 2510c39011c5. Funny little dilemma.
Investors buy on future prospects of a company. While Ford or GM seem like a good value to you and me, where is the future upside to these two companies? They are in about every country, they have vehicles in about every configuration. Tesla has a lot more upside for future growth.

Then again, this is why companies like Ford and GM pay dividends on their stocks ... stockholders don't expect them to grow, just keep making money.

I really hate xkcd.
If I ran a study that said whenever a bell rings at 11:45AM students in public schools exit their classrooms (99% within 2 minutes) and quickly file into the cafeteria, and that this was evidence for mass systemic Pavlovian conditioning, what would you say?

Might you say, "that's an impossibly unnatural conclusion", given everything we accept to be true, including our lived experiences--as students, as human beings.

Of course, it's a _logical_ fallacy to say so. But pure, unadulterated Aristotelian logic has surprisingly little application even in science. While as a logical matter such a conclusion on its face might not be impossible, it's not necessarily hyperbolic to label it so even in scientific discourse. Not the least because everything we know about Pavlovian responses suggests that there should be far more outliers, such that there must be at least some structural component involved, not a purely psychological response. In other words, the result is too _clean_. The real world is much messier, especially in the world of human psychology in complex settings, and the odds of seeing such a clean and consistent response relationship is extremely slim.

Quantum physics suggests that you could spontaneously teleport a kilometer away. Would I be wrong in believing impossible a paper that concluded that you spontaneously quantum teleported from home to work? What if the paper fails to establish--even nominally--the absence of other, less shocking, explanations?

Logically speaking, the teleportation might not be impossible, but in most others contexts (including statistics and other forms and methods of reasoning) one might fairly call the conclusion impossible, preserving the label implausible for scenarios more deserving of critical assessment.
Yep. Redux does a great job of pushing mutation out of your application logic and into the library machinery, much like React does. Together, you get logic that's remarkably pure. It makes for an application that's dead simple to debug.

I've never tried MobX, but it looks pretty impressive too. I can imagine it working really well if you have the discipline to not leak your mutations all over the place.

There's one area that traditional car manufacturers can't compete in: software.

pg said it best when he said something like "Traditional manufacturers vs Tesla is like Microsoft in 1997 vs Apple in 2017"

It's debatable whether software is important enough to matter, but when the most valuable feature of most cars is that you can turn off their horrible software, that's an opportunity.

What do people think of AngelHack
I'm a new developer and I've been going to a bunch of hackathon to try and learn, make things,and meet interesting people. There is an upcoming hackathon sponsored by angelhack which looks very cool that I will be going too. I'm trying to learn more about the organization, but everything I read online seems to be some sort of press release so it's hard to cut through the hype. Do people have any thoughts?
I found it more annoying than buying my own groceries. There are too many ingredients and far too much cutting. I want simple meals that I can prepare quickly. Many of the meals were tasty, but not worth ~1-1.5h of prep time.
Do you have any recommendations on similar services? We tried Blue Apron and found that their only shipping options were FedEx Home (consistently arrives after 10PM) and OnTrac (consistently isn't delivered at all).
And even if you believe that the stock price should be $500, it pays to sell on something that is widely perceived by others as a sell signal and then buy back in when the stock price is lower. Very little long term information is provided by this short term drop.
Accepting reality and feeling like there is nothing you can do about it is the very definition of "normalization".

Exactly. Except that second part is nowhere in the first post.
>The more of us who tough it out, the better for our daughters

How exactly is it better for our daughters?

Anecdote: My wife (software engineer) left the workforce to care for and raise our daughter and she doesn't regret her choice one bit. She says it is far more meaningful work (caring for and shaping the mind of a young child) than making money for some corporate fatcats.
Why would this be an "exception"? The basic item-based collaborative filtering described at the beginning of the article finds items that are likely to be purchased by someone who has purchased a specific item.

I'm pretty sure that it's true that someone who buys a vacuum is much more likely to buy another vacuum. It may seem counterintuitive, and may not be true for you after you just bought a vacuum, but I see no reason to believe that Amazon's algorithm isn't working properly and giving Amazon a lot of value.

Won't having half your state outside the store and the other half inside add unneeded complexity and make your code even more difficult to read?
And in the long run we are all dead anyway.
Already now Leasing contracts enable exactly this. Every odd years you will get a new car but you pay basically for the access to the vehicle not the car itself.
Too bad, I was picturing this as another way for Amazon to deliver packages or perhaps snacks to people (while waiting in traffic)
I walk to the store and buy groceries and then walk home. No cab, delivery service, or drone needed. Sometimes I shop at a store closer to the office and bring what I buy home on the bus [which is typically how I get to/from work].
3 Animals Smarter Than You Think [video]
Here's a recent example

https://www.geekwire.com/2017/amazon-sues-former-aws-vp-non-...

I personally lost a job in NYC post signed offer because counsel at the new company felt that, since both companies were in adtech (though in different verticals), the new company infringed the non-compete. And it apparently wasn't worth the fight.

edit: the lawsuit was later dropped

I doubt amazon refunded the probably $5k+ Gene Farrell spent in the meantime though.
My understanding is that the active gate region is far smaller already so there is less room to scale than you might think.
> Decentralization is always costlier. Netflix is faster and more reliable than torrent

Is it more expensive, though? In a lot of cases it is certainly more expensive (bitcoin, Facebook, etc) but Netflix should be a counter example. In theory, a decentralized Netflix should be a lot cheaper because there are very little bandwidth costs. In practice, though, this is impossible because of all the DRM regulations. There is just no way one could design a decentralized network without getting into legal troubles. Furthermore, adoption would be another problem because a decentralized Netflix would mean I have to upload content and download it. In practice, this would put me a long time into jail if I did that in my country (sometimes even more then murderer and rapists).

We have only seen one such successful "decentralized" application so far: popcorn time. It proves that it can be more reliable and easier to use but in reality the legal implications are just too impractical.

Furthermore, decentralizing other video platforms such as YouTube could be a lot harder. Netflix has a small amount of viewing content but a huge amount of viewers. YouTube has a lot of content and less viewers per minute of content then Netflix has. This means any user would have to store much more then they would on Netflix. There is just no way to save content for a long time. On YouTube I recently found a video I did when I was 13 about a tutorial for a video game. If I stored it on a hard drive, I would have lost it for sure (because I never really cared about it much) and there is no way it would have been stored for some many years by just 3000 viewers who have ever seen that. Just seeing this video after all those years is kind of amazing. I know that there is no guarantee that this video will stay on YouTube forever but the chances are a lot higher (and I don't see it disappearing as long as YouTube stays popular and their main business model is make small video makers big)
It's similar to coffee subscription services that give you a different bag each month. Those services helped me define what I enjoyed and now I just buy coffee directly because I know what I want.

Why would you need different models like "accessory recommender"? If they have enough data to conclude that purchasers of itemA are highly likely to purchase itemB, why not just recommend itemB, even if itemA and itemB are both vacuums and a few people will complain about that on technology forums?
Article does mention the child is 2 years old; not sure if that changes the scope of their refund policy/responsibility. However, I would imagine that if this mother wanted to hold the child in her lap for the duration of the do flight, she presumably would not have purchased an extra $1000 ticket. I imagine they'll for sure give her a full refund and then some after the media flack, whilst still making it seem like their actions were acceptable.
I feel that any sort of quotas will be worked around by restructuring the employment relationship as a business-to-business contract - and there will be pressure on companies to do that if there's significant competitive advantage.
For all you people that expected something by Leslie Lamport, yesterday I learned something very interesting:

Apparently, after the success of the Byzantine Generals paper, his Paxos paper was written as the description of an ancient Greek democracy. Paxos is not initials as I thought but the name of the island described in the paper. His editor didn't like the humor and didn't publish, and the paper was only published years later, after it reached some other researchers and had a lot of impact on the field, in the guise of a "recently rediscovered ancient manuscript".

Please tell me you don't think GS is above manipulating the market [0]. Why can't it be both?

I completely agree that TSLA is overvalued. But that doesn't mean GS is issuing a report and lowering a price target in order to help out small, retail investors like us.

[0] https://en.wikipedia.org/wiki/Goldman_Sachs#Controversies_an...
>> It is not manipulation. The stock is tremendously overvalued.

> This. I was going to say even $180 is still ridiculously overpriced.

My thoughts:

- Goldman Sachs (GS) makes buy helping other people buy and sell Tesla-related securities, profiting whether Tesla shares go up or down, and I simply don't trust the recommendation enough to make bets on the recommendation's value

- No one knows if the stock is overvalued because no one has perfect information about how Tesla will actually perform, including both Tesla & GS

- If I actually did know where Tesla shares would go, I wouldn't tell anyone, unless revealing the price would be a bigger windfall for me than keeping the information confidential
It's worth noting though that the estimates for the Gigafactory have been massively revised (although no one seems to pay any attention to it) and will now be producing 100+ GWh of batteries yearly and Musk had stated that they're announcing 2-4 more this year.
Put it this way. Our brains can't even answer that question.
It's easy to dispute value without looking at all at volume.
This is also known as the Peter principle.
In my last acquisition, as a regular employee, I had to sign a very extensive non-disparagement. I actually provoked a fight because, if I were to obey the letter of the contract, it banned criticizing the acquirer in any way. Before rewriting, I couldn't even offer critical feedback to my new boss.
>It makes me sad to think my kids will think I didn't do enough for them one day

Why do you assume they will look at your decision to stay home (I won't call it "not working" since it is arguably more stressful and difficult than working at an office) and think that you didn't do enough for them?
Definitely, I feel like it's partially just a question of what a full-stack 21st/22nd century auto company is going to be worth once the dust settles after the autonomous car wars. If it still means producing close to 10 million cars a year while also being a leader in autonomous driving software then we could be talking about a multi-hundred billion dollar company in the making. If, however, the number of cars needed to be manufactured drops precipitously and a number of strong competitors emerge in autonomous transport they may end up relying on their semi-truck and energy network investments a bit more. Only time will tell
> Maybe there's something to it, maybe it does a good job growing revenue, but there's noting elegant about it.

It almost certainly does a good job growing revenue, and they almost certainly care more about revenue than about the perception of "elegance." You say that as if it's unusual or unexpected.
Outplacement to protect startup employees during layoffs
It's an interesting point, but I would hope that they would factor in the negative impact on non-repeat-buyers. Some buyers(at the very least: me) feel remorse or regret over their purchase if they are presented with a bunch of other options which may be better or cheaper than whatever they chose to buy.
I said it's a matter of making a choice. I never said making a choice (much less making that choice) was simple.
"Final cause" doesn't imply a designer; it's just the way the species happens to exist. (Aristotle was a deist, roughly speaking.) There's no guarantee that a species' final cause doesn't involve messing with other species'.

There's also no guarantee that a species' final cause isn't self-defeating. Introduce a pair of rabbits to an island with no natural predators of rabbits, and in about ten years the rabbits will eat all the vegetation of the island and then starve to death...
Because it implies an opinion of weakness to the party offering said "help". Many people do not need or want help and forcing it on them only serves to enforce hidden power dynamics on behalf of the requestor.

What I really don't understand is how we men can act so innocent about all this. "Oh, I was just asking a question," "I didn't force her to do anything," "she was free to decline," "what, how could you not want help? Think of all the [rationalizations]!" and so on....

Shut. The. Fuck. Up. Intentions are as clear as the sky on a sunny day...

People who see others as equals treat people differently than those who think they see a potential partner, or victim, or lackey...

EDIT: Also, "mansplaining"
Yes, which is exactly why we should terraform Mars: as a test run of a severe-case rebuilding scenario. If we can handle Mars even at its best (let alone its worst), then we can handle Earth in all but the most catastrophic events.

I personally feel that having a "fallback" in case something literally Earth shattering happens is compelling enough a reason to colonize other bodies in our solar system, Mars included.
