I'm finishing up my first Swift 3 project, a macOS app. The language is well designed, and it took a lot of the ergonomics of Objective C and made them safe. Clearly, Apple learned a lot in Swift 1 and 2, and it is a quite a piece of work.

That said, this is a challenging environment to code in. No attempt at backwards compatibility was made in either the libraries or the language itself. The difference between Swift 2 and 3 is at least 100 times larger than the Python 2.7 to 3 transition everybody complains about. This means that for most of the examples you'll find, they will be in Swift 2, Swift 1, or Objective C; o copy/paste here. Many APIs in the Cocoa and Foundation API are simply not documented other than the parameter names.

Additionally there's "automatic bridging" which can easily convert between new library type and old library types, so there's a nest of transitions (along with the typical inheritance hierarchy for each type) that one must navigate to accomplish even simple things.

However, Swift is clearly in Apple's future plans, so you might as well start learning it now if you have to code for their ecosystem.

I know nothing about grocery retail but my initial reaction is why can't Instacart tie into Safeway, Wholefoods, etc. inventory management system to get a more timely view on what's available? Are existing grocery inventory management systems more rudimentary so this is not possible?

The issue I have is less the rebuttal, but rather the blackmail. They shouldn't reach out to one organization as an attempt to extort more money from another, especially when they are non profits.

That goes both ways.
Wouldn't your exact comment right now be considered unsubstantive since it's a redundant repeat of rules which should have already been read by the user?
Here's something substantive for you, you should really get to work on getting rid of the nonsense all caps rule or fix your lack of italics notation for Braille users.

so there isn't a single floating point representation that can represent all of the numbers in [0,1]

I agree! What I've done is to propose (an admittedly non-computable) set of floating point representations for which you can show a bijection to the real numbers. So if you accept my stretched meaning, which you do so above, then we can answer the title's question with "the cardinality of the real numbers."

This is an interesting suggestion - though I'm not sure of the net effect of iron fertilization? How much iron achieves what?

I guess the legal fees cover dumping of anything ranging from nuclear waste to rubbish destined for recycling? I'd assume one could get those waived if there was a proven positive effect of the fertilization.
And? What's the difference between total coverage in 2018 versus total coverage in 2020? Uber can't lock Lyft out of the market- that was abundantly proved when a bit of ham-fisted PR made Lyft one of the most popular apps of January. And Lyft can just copy any of Uber's random X-delivery schemes that actually works. Self-driving cars might be a distinguishing factor, since as far as I know Lyft has no efforts in that direction, but that deficit could be entirely compensated for if Lyft winds up selling themselves to some company that does have that tech.
> from an outsider's perspective I don't understan

I don't either, but it's related to the outsider status.

Questions I'd be asking would revolve around unit economics - average gross and net revenues off a ride, average rides per driver per month, average rides per user per month, average driver retention and churn, average user retention and churn, all of the above in historic context broken down per market.

Presumably sophisicated investors at this stage are asking for such numbers and base their valuations on cashflow. It's not a pure software business with winner-take-all mentality, Lyft is a Lowe's to Uber's Home Depot.

Oddly, I think outright banning fossil fuel refinement and usage would do more.

Being an only child seems to be a bit psychologically damaging. I could conjecture for pages here, but suffice it to say I believe one is better off having 2-3 children or none at all. Sure there can be situations like being raised closely with cousins or friends that are similarly beneficial, but kids absolutely must have close companions near their own age -- they don't seem to fully learn to be empathetic otherwise.

This is only the opinion of one person, take it however you wish.
Yes. WFM has an equity stake in Instacart and has benefited (income diversification + investment appreciation).

That said, from what I'd read (and it's been a while), WFM's strategy with Instacart sounded like a way to steal market share and convert customers to shop IN their stores. If I recall, Instacart pickers were getting bonuses for (choosing) WFM stores, and WFM was offering food to pickers with no markup.

I don't know if it'll work out. WFM's been under fire for it's pricing for a while. Maybe Instacart will drive incremental sales growth (as you're alluding to). I'm skeptical as it might cannibalize the value of their high-cost experience locations.
I wish some billionaire would start a chain of carbon neutral gas stations. I wouldn't mind paying more for gas if I knew it was carbon neutral. There are several ways the gas could be carbon neutral, either through production (solar/wind into fuel creation) or offsets (plant trees or carbon sequestration). Instead of slowly trying to change our transportation infrastructure to EV, which will take decades, this could have immediate impact now.
Counterpoint: one of the reasons I prefer Uber is that it doesn't allow or encourage in-app tipping. Tipping sucks, is economically dysfunctional, and socially awkward. If the drivers aren't making enough from base fares then the fares need to go up - it's not my job to be a charity.
I don't think a carbon tax is ever going to be politically viable.
> Money is just a paper form of trust.

Although it's impossible to know with 100% accuracy, a lot of historians believe that the origins of money tied up in the creation of empire and slavery.

As you say, smaller societies didn't need money and worked on favors. As armies began being created, soldiers wanted something concrete up front, because they could die before you repaid the favor. So they settled on precious metals and eventually coins. Someone has to mine for these metals and mining is backbreaking work. The solution was to take conquered people and turn them into slaves. This is the vicious cycle of empire...armies need to get paid, so you need to plunder and conquer people, you have more territory which requires more soldiers which requires more coins which requires more slaves and on and on.
This just sounds like fickle, no?
I agree this would make sense in countries with high birth rates, but applying it to countries with low birth rates would just accelerate their extinction. Also partially related, but movie "Idiocracy" (http://m.imdb.com/title/tt0387808/) comes to mind here.
There are some flaws in your assumptions. You assume everyone that drives has the same license and that driving requires little skill. Some speciality driving requires skills. These drivers have to have Class A CDL licenses and have to pass training. I highly doubt automated vechiles will obselete every driving job that requires a CDL license in the next 5 years. Eventually? Quite possibly. But in 5 years? Most likely no.

I'm not claiming every Uber / Lyft driver has a CDL license (most probably don't). But to claim driving requires no special skill is false. There are certain situations that require very specialized driving skills.

This is also Uber's supposed mentality, but you are wrong and Uber is misleading the public.

If a part time job is profitable, then doing it full time would also be profitable. The biggest lie in their marketing campaign is their claim that Uber is about ride sharing, but that's serious bullshit meant for fooling drivers and legislators, because the driver cannot control the passengers' destination and they take a pay cut when rejecting orders.

You see, the drivers that are upset are those that have done the math and realize that they cannot cover the maintenance costs for their personal car, along with what they lose in time spent in commuting and maintenance and still make a worthwhile profit.

At this point Uber survives because they found enough gullible drivers that waste time and add serious mileage to their own cars for Uber's profit. But at some point the bill kicks in.

None of my grocery stores within the 60 minute range offer delivery. I wish they did. I live outside of a major city, in a pretty wealthy area.

I had the opportunity to speak with an Uber driver today who spoke with a gentle voice and was very pleasant. She didn't speak much and when she did, she was very agreeable. However, when the Uber topic came up, she was very vocal about how unhappy she was driving with Uber (She did not know about the recent Uber drama going on because she was so busy driving all the time).

She complained about Uber's frequently changing driver bonuses. Right when she figures out a routine that fits her schedules, Uber sweeps out the rug from under her and changes the payment structure.

Example: Previously you complete 125 rides / week and you will get a $500 bonus. This a significant number for her. Now, Uber split it up so you have to do 75 rides by Thursday to earn $250. Then do 65 rides on fri/sat/sun to earn the remainder $250. This is incredibly frustrating for her because on weekends she usually gets long rides (SF to San Jose). This immediately takes an hour off her day (for one ride) and she would have to work extra to meet her target.

Obviously, I asked her why she doesn't drive for Lyft. She used to, and Lyft did many things right. She loved it. However, Lyft decided to take away Lyft power driver bonus (similar to Uber's bonus) and that made a significant dent in her earning potential. She had to switch and drive for Uber to make ends meet. I'd imagine many Lyft drivers had a similar reaction, which is why I still find much more drivers on Uber than on Lyft despite the all the negative publicity. Here are some things that I think Lyft can improve on their business strategy:

1. Be willing to do what it takes to succeed. Uber has repeatedly shown their agility and versatility to adapt to changes around them. When they realized that Uber Black was not what the public wanted, they introduced UberX (which screwed over alot of their existing drivers) and lowered fares. It was harsh and unfair, but it had to be done.

If I was running Lyft and was low on cash and could not afford to continue driver bonuses, I would have laid off a chunk of the engineering team / staff to raise capital to retain the drivers from switching.

2. With all these #deleteUber hashtags, why haven't I heard any of my friends promoting Lyft? Now should be the perfect time to splurge on marketing and capture all the disgruntled uber drivers and passengers. Wait a month, most of the fire would have died.

As much as I love Lyft and the experience I have riding with Lyft, I prefer giving that up for a cheaper service. Most people I know would prefer to save money. I hope Lyft figures out an aggressive business strategy and become a viable Uber competitor.

I would swear when i first installed Uber, they were clear tips were built in to the price of the ride. I believe there was even a screen on signup to select 10,20, or 30% tips - i might have imagined that part though, it was years ago.

Uber's claim is that black people are known to tip poorly, and so drivers would be incentivized to cancel their rides in favor of fares they expect will tip better. Therefore they don't allow tipping to prevent racism. Supposedly...
Especially in a world where Google Maps has already intermediated the ridesharing services. NotUber just needs to integrate with gmaps to instantly get ridership without spending billions in incentives to build their own two-sided marketplace.

When that happens, any Uber employees still holding equity are going to take a bath. They will be holding onto shares likely worth less than what they paid in taxes to get them.
I suspect that the population of every country is too price sensitive for this to make a dent. Take for example ethically produced clothing, food, etc. While they are big industries they can barely hold a candle to their less-ethical counterparts.

From what I see, relying on good intentions doesn't quite seem get us to where we need to go.
You're Kinda remembering right. They definitely marketed it as tips were built into the price and even had a policy where drivers had to refuse tips.

Genetic variants are correlated. If you have thing 1, then we can somewhat predict thing 2 and thing 3 and so on.

Thus the effects are not really tiny. The direct effect of a genetic variant may be tiny, but it is associated with many genetic variants with similar effects.

This is most obvious in the Ashkenazi population, which has been so strongly selected for intelligence that it now suffers from numerous recessive problems. If you have a trait found in that population, the chances are good that you have other traits found in that population.
I feel Uber does a (slightly) better job vetting their drivers. I've had a few very questionable rides with Lyft. Most drivers are great but I've had more bad drivers on lyft.
If I had to guess, abusing growth means taking advantage of the fact that a lot of investors use growth as a core metric in their decision-making process. Thus, Uber optimising for growth over any other "more reasonable" option, just to obtain funding.
SEEKING FREELANCER - NYC (Lower East Side)

Gig: a frontend engineer, experienced with React&friends. At least 3+ months, with an option for a full-time role after.

Hi. I am a self-funded developer working on an enterprise SaaS product that is starting to get traction. The product is used by managers to smarty distribute $10M+ within their company, so there are many fun BI/UX/workflow challenges.

The stack includes all of the current hotness: React, GraphQL/Relay, webpack, postcss, jest, offline-first, I18n, d3, etc. I've been building production apps with React since 0.8 and continue to re-evaluate all developments in the field. Frontend fatigue is my jam.

I am looking for an upper-mid-level JS developer with React experience to work with day-to-day. The gig would be perfect for a entrepreneurial developer who wants to dive into the deep end to level up like crazy, while watching their work go into production. The rate is so-so ($9k/mo), but in return I offer a challenging young project, sharing everything I learnt over 17 years, no BS corporate/meetings, a pathway to master the most in-demand front-end tools and technique, and maybe even join something before it blasts off. I can guarantee 3-4 months, then the venture will either explode or implode - either way will be fun to partake.

If any of that sounds interesting, drop be a brief note and we'll chat. Do you remember ROT13? Say hi to rhtrar7@tznvy.pbz

P.S. Because of the nature of the working relationships, unfortunately I can't do a remote engagement for this role.

costco and mars incorporated both have long histories of ethical, sustainable practices, and a strong reputation for resisting the quality lowering death spirals that infect many consumer goods focused companies.
I completely agree, and was halfway through writing a similar comment when I saw your post.

I actively make choices for things like transit and food which reduce how much I have to think about tipping. I don't like having to judge someone's service, and decide how much it's appropriate to tip them based on some unwritten societal rule.

The signal that hiding tips away sends is "the service provider is being compensated already", and if you want to make an extra effort to pay them more you can, but it's not required of you.

I'm absolutely in favor of Uber/Lift charging whatever is necessary to pay their drivers properly. Similarly, I love no-tip restaurants which pay their servers and kitchen staff living wages.
Recent studies say that iron fertilization sequesters a lot less carbon than you might think, so maybe we should defer worrying about the economics until we know how much carbon it sequesters?

Telling poor people that the only power they are allowed to have is too expensive for them to afford does result in their having shorter lifespans. Energy is one of the keys to modernity; you can't power an MRI machine with UN-subsidized corn.

The AWS "Region" which the super secret stuff runs in isn't plain GovCloud. It's Amazon C2S. It's not talked about much (at all). From my understanding, most people who work on this cloud do not need a clearance but do need heavy background checks.

Some people operate directly with the intelligence agencies (and work on their campuses as part of their duties for AWS). These people often handle sensitive data and therefore need clearance. Amazon often hires individuals who are located near intelligence services to ease this.
Thank you. Just pay a reasonable wage and don't have them rely on begging for tips. Encouraging tipping is basically saying "We don't pay our workers enough so you, consumer, must make up the difference, or feel bad when you don't."
Selling employee vested stock privately to current investors
I keep getting contacted by former coworkers (engineers) who either recently left, or, who are miserable and want to leave somewhere where I used to work. The common thread is they cannot afford to exercise their vested options and pay the tax so they are letting options expire asking me for advice since I used to work there. Is this really common among other tech companies? Shouldn't the current investors (institutional or otherwise) have some interest and ability to buy up employee vested stock?
