This is what gets lost in all the negativity. Lyft/Uber can slash their R&D by 90% and they wouldn't have much trouble running normal operations as minimal app-based cab companies. At 2,000 minimally required head count for running operations, they would probably average $2B in annual expenses. However suddenly they would be gloriously profitable with huge scalable upside and small fixed costs.

Here are some calculations:

Currently per mile cost of car (fuel, vehicle, insurance) to driver is about $0.50. Uber/Lyft typically charge $2.00 per mile so $1.50 goes to driver. Subtracting cost of car, driver pockets about $1 per mile which translates to $30/hr in urban areas.

One issue however is upper limit on the business. There is probably demand for 100,000 cabs each hour in US. That translates to may be 2-3 million miles per hour. if Uber can capture 30% of this, then their US revenue would be at about $4B. The international revenue perhaps adds another 2X so we are looking at total revenue of about $12B @ 30% market share. There is room to grow by almost 100% here in terms of market share so with $24B revenue and $2B of minimally needed fixed cost for operations, this seems fairly sustainable and astoundingly profitable business to me.
Vegetable in a botanical sense just means "plant", so even if you for some reason insist on using technical terms in non-technical discussions, avocados are still vegetables.
> Commercial farming of those vegetables, at least in some parts of the world, often involves migratory beekeeping.

> Vegans avoid animal products. For strict vegans this means avoiding honey because of the exploitation of bees. That seems to imply that vegans should also avoid vegetables like avocados that involve exploiting bees in their production.

It seems like there are some vegans who consider it. If exploiting bees for honey is non-vegan, why would exploiting bees for other purposes be acceptable?

The current NASA spending is ~$22,000/kg to get into orbit. Elon and NASA both see that getting down to ~$200/kg by 2070, only 50 years away.

When we're talking about $200/kg, the launch site's location relative to the equator will become a BIG deal. You'll see a ~4% difference in cost per kilogram (wildy estimated here) if you are more than 17 km off the equator. That means if you wnat to launch your 160kg-self more than 17km from the equator, it'll be an extra ~$1400.

For a lot of reasons that my posts explain much better, buying certain Somalian real estate is a VERY good move right now. Granted you have to be muslim to do so.

Design quality for a UI, ordered easiest to hardest:

1) Information dense

2) Looks good in screenshots

3) Information dense and easy to use

4) Information dense and easy to use and looks good in screenshots

An awful lot of designers stop at 2 because a 4 is way harder to achieve, yet a 2's pretty easy to sell (to "stakeholders"). The result is at least sometimes (sometimes) better than a 1. They may also drop a 3 to a 2, though, and it's really hard to later turn a 2 into a 3 (since it's "uglier", so harder to sell) and a 2 is so different in character from a 4 that it can't even really be considered progress toward it (a 3 might be).

Why are so many recent question titles starting with “Say ”?
This is technically true, and a common reposte when talking about preservation of history edits.

Unfortunately, the reflog is confusing and hard to use correctly in the case of an interactive rebase with multiple steps. It is hard to figure out exactly how far back you need to go in the reflog to get to moment before the rebase started if you want to start over. It also just so happens that its when an interactive rebase goes awry that I really want to reach for the reflog to fix the damage.

Much of the ahead-of-the-curve, aspirational tech stack posts featured on HN are the blogging equivalent of Instagram-polished shots. On a personal blog they're equal parts self-expression and self-promotion; on a company blog they're equal parts deep dive and recruitment teaser. It's okay. Some readers will feel intrigue, some confusion, some envy. They'll wonder why they can't use those new tools at their work.

It's nice to recognize there exist developers who seem to stand apart from the vocal ones who make these posts, but they're not a single class. Some brag just as much, just in different circles. Some don't brag, but they do lots of good work. Some put out work that's not so good, and they may or may seek to represent their accomplishment regardless. The only factor they clearly share is their underrepresentation and their lack of attained popularity in talking about their work on social media.

As tempting as it may be, it's a big reach to conclude due to their underrepresentation that their tech stacks are conservative, or even dated; it's not a given that their work is solid and they're hard at work solving business problems given numerous constraints and office politics. Efforts to define this population by their rejection of shiny hype just perpetuates a kind of fictitious class divide between "fancy" developers and "plain" developers, when the real class divide is between management that is desperate for results, and IT workers that are desperate for empowered decision-making and resources. Businesses are under tremendous pressure, and silver bullets read about elsewhere carry great appeal. Transplanted organically by enthusiastic developers or by order of management, such solutions rarely work, because changing just a few inputs of a complex process won't deterministically give a better result. And mediocre results of a messy process make for a different genre of writing.

Maybe there's a class divide after all: between developers who are privileged enough to cook up all sorts of clever, custom solutions to challenging problems and can write about it, and those who spend their whole workday surviving the onslaught of nonsensical demands and deliver something mostly working in the end.
Not sure I understand - are you showing HN not your project, but its launch announcement on some other site?
Using java8 in 2019 is pretty normal. It's "only" 6 years old (released at the beginning of 2014), nothing like the cobol horror stories. The 6 years old java is not very different from what software you get from debian stable. The next lts java11 was released at the end of 2018 and does break some things so you need time to update. It was supported by oracle until Jan 2019, while other vendors have pledged support until 2023 and more.

And most importantly java8 is still a decent experience.
This is the part I don't get. Right now they rely on their employees to buy, maintain, and depreciate their own cars. The natural next step would be to let people lend their cars to Uber/Lyft when not in use.

But they're sinking tons of money into self-driving, which means they would bear the costs of buying and maintaining their fleet. That's a completely different business model, and seems like a tough pivot. And as mentioned elsewhere in this thread, other companies are better-positioned to do this, with better manufacturing, more sensor data, more experience, or all of the above.
Obviously not. They're striking.
$30,000 for a Civic? You better be getting gold-plated cup holders at that price.

What's common in Philippines is for higher middle class to buy a vehicle, and pay a driver to drive it for Grab. So the capital of buying the car is not done by the driver, and the drivers gets a lot less than what you pay.
> Shorts very rarely actually get closed out by a prime broker (at least for institutional investors).

This is technically true, but far away from what actually happens. What normally happens is that when borrow gets pulled the prime will notify the firm that they have to close the position for T+2 settlement.

There is a 3pm buy in window but you are correct that its not often that the prime is forced to do it because they make it clear to the firm that at 3pm they will send a market order for the required amount, this will almost always result in the firm buying back the position before this comes to pass.

Occasionally the prime will find other borrow but often that borrow has multiple issues that make it unsuited for holding a short position for more than a day or two.

1) unstable and could get pulled at any moment.

2) rates are much higher than what the firm was currently paying

So theoretically you are correct but practically speaking not so much:) The firm will usually just close out a position at this point unless they have a firm conviction that they can make a profit at the increased borrow rate and ride out the moentary pop.

And with borrow rates that can did approach 60% for lyft you are betting that Lyft will go down more than 60% inside of one year.

Possible but not very likely, you can be directional correct but still lose due to your borrow fees.

Retail doesn't help much for larger firms with borrow as the market isn't near as large as the institutional market. Though maybe you just are used to trading in smaller share quantities than I am:)
I had to Google it:

They mentioned there are ways to access the ID in different ways if needed, i.e. you could allow NFC'ing the ID even if the phone battery is dead, so they will probably have a way to access the ID without unlocking your phone entirely.

The company that delivers fully autonomous vehicles would have no trouble securing funding to not have to operate within Uber's walled garden and give Uber a 22% cut of profits, and make their own app. Remember, when the independent contractors go away, you don't need offices in every city to onboard drivers, you don't need a big legal team to fight the ongoing "are they contractors or employees" debate, etc.

In other words, the company that delivers autonomous won't need $10B to make a cloned Uber app. Since the driver is the biggest cost for Uber, riders will gleefully switch to the clone at even cheaper prices.
because if you look far enough down the rabbit hole, nothing is vegan. Hence "as far as is possible and practicable".

If you are vegan except honey, good for you. If you decide that doesn't fit your worldview/morals, then good for you. If all you care about is meeting some other persons very specific standard of veganism, then you are probably doing it for the wrong reasons to begin with.

They do know a lot. But the work the analysts are doing is price of entry stuff.

You don't make money on Wall Street by "knowing a lot" you make money by knowing one thing that one person opposite you doesn't.

That means you have to know a lot of things that won't make you rich, just to prevent becoming poor.
Lyft seems to have a lot of shorting. People are heavily betting against it. They expect its price to drop.

However, while it may be true that in the long term lyft will loose value, something weird can happen in the short term:

Shorting requires borrowing shares. You pay a fee, borrow the share. If it looses value you make money. But if it gains value, and you are asked to return those shares back, you can loose a lot of money. Also, the act of asking for those shares back could raise the value, creating a negative feedback look. Disastrous for the short seller.

Why might we see lots of shorts being asked to return the shares back? Due to the large amount of shorting and the bank wanting those shares for other purposes.
That it's often extremely difficult and lots of overhead to have such a thing, and clients typically are larger than you and have less to loose by arguing about it endlessly.

Lisp has compilers.

Some do also some type checking, here SBCL 1.5.2:

(declaim (ftype (function (fixnum) string) bar))
(defun bar (a)

"not-zero"))

(defun baz (a)
(foo (bar a)))

I've never experienced this. Particularly, I don't experience this with Discord, and Discord is to Slack what a bee is to an ant, which is why I juxtapose it. (And I would ask if it might be something on the Slack side, but you say it happens with everything.)

Never had this either.

I think a real vegan would not be spying on innocent rabbits in their holes.
Vegans own smug and 'ethical checkmate' inanity - the 'eco' ethos of food goes hand in hand with this, they are the same thing; don't blame outsiders.

The whole thing is bizarre, who is buying these stocks?
That depends. You are legally correct. Most shops when seeing a do not duplicate key will do some checking to see if you should be allowed to duplicate the key (but there is no standard here), compared to any other key which they will duplicate no questions asked.

Also some "secure" keys don't have any blanks. Most shops don't have the ability to duplicate them. You can still get them copied, but you need a skilled machinist at considerably more cost.
Triple the estimate.
That's the pathetic "liberal" sexist caricature you see on TV and media. And like most caricature in media, it's nonsense.

The problem is that both men and women are deciding to having less kids. And that trend has continued with maternity leave, paternity leave and even paying people to have children.

In poor countries, they have more kids. Is that because of your caricature or lack of it?

Europe has provided great benefits to women and men to have more kids. Birth rates have declined.

https://www.thelocal.it/20180627/italy-declining-birthrate-p...

Governments are even paying women to have kids and that hasn't helped.

https://www.npr.org/sections/money/2011/11/03/141943008/when...

The only thing that increases birth rates is an increase of poorer and less educated women. The wealthier and better educated women are, the less children they have. That is the only consistent correlation across ethnicities, cultures, religions, etc. Educate women and reach a certain level of wealth and birth rates drop.

It's true in japan

https://thediplomat.com/2018/01/japans-births-and-marriages-...

korea, china to iran and all the way to europe.

If we really wanted to increase birth rates, kicking females out of school and removing any and all benefits would be better than increasing benefits. It's counterintuitive, but it's true. Or maybe we could accept that population decline is going to happen and prepare for that? It's strange how we think we can bribe women to have more children. That's never going to happen, so we should learn to live with our current reality.
I hate these stupid arguments. The entire point is to muddy the definition of a word so much as to render it worthless for political reasons. It's like how assault rifle was a well understood term in the 70s and 80s, but today groups quibble over technical minutiae in an effort to invalidate the term.

As with most labels, the word vegan has a fluid, rough definition which varies slightly over time and person-to-person. If someone tells me they are a vegan, I know they are trying to tell me that they avoid foods that use animal parts or their byproducts. It's not some fucking contract they entered into prohibiting them from eating whatever foods society decides to impose the vegan label on via mental gymnastics. If they are cool with eating the butter made from Betsy, my happy cow, then whatever, let them eat the butter.

FWIW, I'm a carnivore and object to the consumption of almonds because of their harmful impact to the environment. That might make me a hypocrite to someone because I'm totally okay with eating a banana or something. But I don't care, I'm free to decide my own arbitrary moral compass for whatever reason I choose.

I guess I'm aggravated by society's needless pedantry over language. Not every word needs a rigid legal or technical definition that should be adhered to. And the people guilty of this are largely doing so because they don't agree with you and are attempting to make you look stupid to justify their position.
