It's maybe possible that Amazon has access to lots of capital if desired. Hell, they have "bronze-infused stainless steel" as a material option - I think it's obvious that Amazon isn't using hobby-grade 3d printers.

I think a 1* rating for a free game relying on ads or IAP is a bit rough unless the requests are brutally intrusive. In the case of our game, we show an ad between each game that is instantly dismissible. 10-20% of the time we show an upgrade modal in case people want to ditch the ads and get extra features.

One of the ad networks we beta tested had unskippable, 30 second video ads with sound!
I disagree with this. The key isn't the technology but building the better driving experience.

If someone comes out with a vehicle with on demand torque, a 0-60 time under 5.5s, excellent handling, and most importantly, great styling and interior, I'd consider it. Tesla vehicles are able to stand on the merits of the driving experience, EV or not. That's not something no other EV manufacturer can currently say.
Imagine what will happen when we combine decentralized car use with autonomous driving. Uber is already cheaper than driving yourself around, but think how affordable it would be if no Uber driver was needed at all.

You can't possibly be comparing the binary and source compatibility of Java with Scala can you? I'm not an expert, but I haven't experienced a binary Java incompatibility in the wild and I've been using Java since before 1.0. As far as source compatibility you can count on 1 hand the incompatibilities between Java 1.4 released in 2002 with the current release and Java is not a paradigm for long term support!

Instead of trying to shoot down everyone that points out an obvious disadvantage of Scala, and the backwards compatibility issue is an obvious one, a better approach would be to highlight what that trade off provides. Namely, Scala is free from the problems brought on by Java's strict backwards compatibility requirements and can continue to dramatically improve from version to version.

You'll transcribe the kanji, but you won't read the goddamn article?

"The area was a major producer of silk and prospered from the Meiji period through the Taishō periods. As the demand for raw silk declined in Japan and abroad, Koromo entered a period of gradual decline after 1930.[2] The decline encouraged Kiichiro Toyoda, cousin of Eiji Toyoda, to look for alternatives to the family's automatic loom manufacturing business. The search led to the founding of what became the Toyota Motor Corporation.

On March 1, 1951, Koromo gained city status, and absorbed the village of Takahashi from Nishikamo District on September 30, 1956. Due to the fame and economic importance of its major employer, the city of Koromo (挙母市?) changed its name to Toyota on January 1, 1959."

> This calculation is why I think Uber is still undervalued. The people who say Uber is only worth $4 billion or whatever don't think enough about people like me who will go from spending ~$500 a year on taxis and car service to ~$12,000 now that the experience and cost have reached a tipping point.

This is a lazy analysis.

Are there folks who will trade car ownership or public transportation for Uber and services like it? Absolutely. But what is the size of that market? How much of that market has Uber already tapped?

Sam's post assumes that Uber's current valuation doesn't take into account this segment of the market and that this segment of the market still offers Uber significant growth potential. Maybe he's right, but he provides absolutely no evidence and doesn't even attempt to come up with hypothetical numbers for consideration.
Still not sure how this would work for anybody with a family and kids and/or living outside of urban areas (the majority of people). Has this been touched on in previous discussions? Would love to hear some thoughts.
And yet, if there is an idiomatic Scala (and the lack of one is a huge problem with the ecosystem) it's that nobody uses function syntax for Unit return types. So in order to get rid of a class of bug that is minuscule compared to others you are going to require hundreds of thousands (millions?) of lines of code to be changed. It's that kind of lack of real world perspective that causes the Scala community to be derided.

The most recent version of the Xlint/future features are useless because of this blind spot making so much noise in the output.
That's definitely understood. I suppose I'm wondering at what rate people encounter behaviour like this. For me, this early on, it seems rather common, but my sample size is extremely small. How often (e.g. what % of leads) does this happen to the average, experienced consultant?
npm has the same problem of sending packages over http, but it's even worse since on average each node package uses about a billion other packages and because injecting malicious code in JavaScript is incredibly easy.

And to be clear, just http here is not the issue. It's http combined with lack of package signing. apt runs over http, but it's a pretty secure system because of its efficient package signing. Package signing is even better than https alone since it prevents both MITM attacks and compromise of the apt repository.

In fact, apt and yum were pretty ahead of their time with package signing. It's a shame others haven't followed their path.

Every couple of months one of my friends insists that she's "quitting Instagram" because of how often things go wrong on the platform. Several times a month she gets logged into someone else's account with full read/write/update access and I believe even gets access to their Facebook. Between the above, the 4+ accounts she's has deleted for no reason, and the bugginess of often having a blank UI, it's becoming harder and harder to enjoy browsing on Instagram.
Wow, that's really disheartening to hear. I've personally never seen that around here (thankfully), but now that I'm over my minor obsession with Dogecoin I don't spend much time on Reddit.

Yes, actually, it was in a lot of cases. From the aggressive use of NINA loans (in some cases targeted at minorities) to selling mortgage-backed securities while betting AGAINST them, the financial industry had a much larger hand in this.

> are they not equally guilty of wanting to one-up the next guy with a bigger house, a quick flip, a granite countertop, or a cash-out refi

1) The assumption you're making the insinuation that all homeowners engaged in this kind of activity which is an existential fallacy.
2) In situations like this, where one party (the financial industry) has more training, connections, influence, and knowledge and the other (homeowners) have CNBC, it's a stretch to say that the homeowners are the ones to blame.

100,000s of people do that every single day. It is a bridge. That is what bridges do. They carry largely unknown people across a highly visible structure.

I think you are blowing this out of proportion. Or maybe I shouldn't use the word blowing.
And guess who takes most of the heat if/when irresponsible drone operators cause problems for others? I think they're a lot less worried about quadcopters and suchlike than the potential for accidents involving large RC planes like the Skymasters, some of which have a 10 foot span and approach airspeeds of 200mph. I don't know what their ceiling is like but I've already heard a lot of grumbling from general aviation folks about the cavalier attitudes of some RC pilots, so I don't think the FAA is just throwing its weight around for no reason.
Ceasing to dream big isn't an improvement. But ya... it's probably for the best the project didn't happen (yet:).
This is what excited me about Google buying part of Uber -- self-driving Uber taxis. Combine that with electric vehicles that can intelligently remove themselves from the swarm of cars and be replaced by a charged vehicle, and you have on-demand, cheap, and potentially environmentally more sound taxis.

I'm a huge fan of Sam's blog posts and he is President of YCombinator for a reason, but I'm struggling to understand what Sam think that his personal data point (as a wealthy owner of a Tesla Roadster no less) says about the viability of Uber replacing a family vehicle for normal people. Does he not realize that plenty of people love to drive?
I would like to see a comparison between Uber, car sharing (like Zipcar or Car2Go or whatever local carsharing organization you might have) and car ownership. I'm a carsharer, and between me and my wife we spend about $500/month on carsharing, which looks about half of what it costs Mr. Altman to own and operate a Tesla Roadster.
I do have sympathy for them usually, just not when I wrote that. ;)
he lists four: teespring, zenefits, stripe, and optimizely. anyone know the fifth?
Two thoughts:

1. People will move back to cities as cities become more attractive (thanks in part to things like the shared economy). There's already some evidence of this trend among millennials. Reverse white-flight if you will.

2. Uber will eventually work just as well in suburban areas. The fundamental economics don't change (higher resource utilization => lower costs). It will take longer to get to penetration levels that result in sufficiently high utilization. But we'll eventually get there.
My wife and I moved to SF ~6 months ago from Mountain View. We sold one car almost as soon as we moved, as we definitely didn't need a car each. Just last week got rid of the last one as the math really didn't make sense.

All in, gas, insurance, car payment and parking spot we were spending over $900 a month on unavoidable monthly costs, at times this number would also go up based on using the car to get around the city and having to pay $10-40 to park the car at wherever we were going.

Add it all up and that same money can buy a lot of Uber/Lyft/Zipcar at 90% of the convenience. I've yet to see how much we'll spend monthly on various transportation services but so far it looks like we'll be saving close to $400/m.
How does it know what the correct signing key is?

edit: Looked up answer myself. Lein downloads whatever key the signature claims to be made with from public keyservers. How does this provide any additional security over not bothering to verify signatures?
'halt' would work just as well as 'kill' but the latter sounds cooler. It's OK to use jargon within a professional context, but using it without regard to one's audience is generally obfuscatory.
You used the wrong Distro :) Redhat or SUSE.
I look forward to reading the breakdown on how bad the security for this system ends up being.

I can see it now - each lock would be connected to the hotel's wpa-wps network (shared with the guests of course) and use a dhcp server without static routes to assign IP addresses. Maybe if we're really lucky they'll be using some consumer-grade cisco switch with last year's firmware update.

Snark aside, they have to be _really_ careful not to fuck this up. There's so many potential attack vectors in this kind of system it's nuts.
lol @ 5k a year depreciation, 3.5k maintenance, and 3.6k parking, i.e. the majority of this analysis.

In conclusion, paying someone to take you in their Toyota Prius is less expensive than paying for your own Tesla.

Still, I see sama's point. I own/maintain my own motorcycle and I uber/lyft when I can't do that. Best of both worlds.
Despite that suburban families are perhaps the least likely Uber demographic, it actually can work well and will likely continue to get better. First, kids in their teens to early 20s might not even have a car. Seniors might not be able to or want to drive. Parents might want to be driven to parties or nights out. Two driver family might be able to avoid that 3rd vehicle. And on and on.

It's not really that helpful to wonder about the worst scenario, especially without any imagination whatsoever.
Simple answer: Available advertising space.

The identifier field in the iBeacon spec is a 16-byte UUID and no longer than that, AltBeacon has a 20-byte space but its because it includes an unstructured major, minor (compared to iBeacon). If your example was to be represented it would be 22-byte in length which is outside the bounds available — granted that I took the number of X literally and could be shortened multiple ways.

Moreover, the UUID is described as a region identifier where, in your scenario, all the beacons for the bus company would have the same region identifier but each individual beacon representing a stop would have an individual major and minor identifier (2-byte each) to uniquely identify that particular stop. So the way in which the iBeacon spec and somewhat AltBeacon are authored don't really allow for that kind of implementation because of the limitations imposed by the small advertising packet space. Its intended that the identifier space be used for something like a UUID with a set of supporting identifiers (major, minor).

As you can see from the AltBeacon spec diagram; there is only 28-bytes available for advertisable data on a Bluetooth Smart peripheral. So there is not a lot of room to play with.
Sam. You own a Tesla Roadster, a car for people who don't have to niggle over money.

Most people a) don't live in SF b) have your money c) have access to Uber and d) have a Tesla Roadster.

You're essentially talking to yourself and a few choice friends who live in the same bubble as you.
It was not meant as click bait.

To me the interesting portion of the article was the "Yes, if" instead of giving the answer of 'No.'

The tab in the browser says "Why Killing Cash is the Key to Mastercard's Competitive Strategy" but the title on the page is "MasterCard’s Ajay Banga: Why ‘Yes, If’ Is More Powerful Than Saying No." I typically don't pay attention to the title in the tabs.

Anyway, I found the comments on the article interesting even when the discussion went where I didn't expect.
In Kazakhstan you can hail any car on the street - the cost of travel would be about 5 dollars. People still buy cars because for certain trips it is inconvenient (e.g. going to/from an airport, shopping, travels outside cities, non-popular routes). This system also coexists with normal taxi services which are more expensive but the fares are still suppressed.
I don't see the point of downvotes here... I have several production deployments of NixOS, and can't imagine using any other OS / package manager (supplemental utilities are fine, of course).
I used to live in a smallish german town which had an excellent car sharing service. They had about 15 cars of all sizes all around town which you could rent vja phone or web for as long as you needed then. I paid 11 euro per month and in addition 3 to 10 euros an hour (depending on the car) and some cents per km.

Tbis service was perfect! Need to go shopping for the weekend? Take the vw golf. Cat needs to go to cat doctor? Take the smart. Want to help a friend with moving? Take the mercedes sprinter. Want to go to the beach with some friends? Take the vw passat.

All in all i paid 20 to 50 euro for _all_ my car needs and i never had to think about refilling gas, switching to winter tires, do checkups and so on.

Unfortunately i had to move to a different town where such a service does not exist and i really really feel limited. I need a car only once or twice a month so buying one is out of question. And renting from a normal car renting company is too expensive.
Isn't it exactly what they are doing, though? The only reason you would want HTTPS is to prevent MITM attacks. By making it a premium feature, they are making MITM attack mitigation a premium feature.
This is the case in any technical occupation. The femur is called "femur" instead of "leg bone #1." The one benefit of this is that it makes it extremely difficult to fake being an expert.

I often think that the ability to easily identify experts would help in republics, but i am not so sure. On the other hand, you have Lessig's approach in republic lost. That the problem is the money, and not the non-technical politician.
it's definitely an extreme data point, though car ownership in SF is expensive no matter how you cut it (most of that maintenance goes into fixing stuff that happens to it when parked on the street, and parking garages are always expensive).

i could definitely get a car that depreciates less. it's old battery tech at this point.

I'd love to do that, but when people are only interested in repeating stuff they read somewhere on the internet, but not discussing interesting things like how union types will change the way people will write code, how collections could be improved, or how the arity-limitation of tuples could be dropped–because that would actually involve thinking and doing some research–it's a hard thing to do.
Especially when it's likely that I'm going to be accused of "moving the goal posts" when doing that.

It's kind of sad that there is pretty much no insightful technical discussion happening on HN, but at least I can have some fun with "somebody is wrong on the internet" when people make wrong claims.
This article has several misconceptions ignores a few other considerations. consul is doing raft consensus for data replication, and its k/v api is not gossip based, its strongly consistent. the author seems to have missed the comparison to serf on the consul website which might have elucidated some misconceptions that ~'gossip is used to transmit all data'. the article also seems to be under the misconception that you have to run serf binaries as part of consul (its embedded gossip lib). it also ignores the operational simplicity of a single binary vs. managing a zk cluster + smartstack setup. zk (at least till whenever 3.5 comes out) doesn't tolerate dynamic cluster reconfig nicely without round robin restarts. it feels like a pretty biased or uninformed comparison coming from the author of one of the things being compared (partially forgiven as a result of it being a response to a comparison being made by the other software).
oh wow this is fun
To be fair, the Tesla Roadster is a pretty odd example. I'm not sure $5,000/year depreciation with $3,500/year for maintenance seems reasonable for almost anything. Am I wrong in thinking that most cars depreciating at that rate will have very low or 0 maintenance costs not covered under warranty?

For example, a 2014 Honda Civic with 1 mile on it (example) is ~$17k, while a 2013 with 6k miles is ~$15k (KBB values). There should be very few things not covered by warranty since they're <3 years and 36k miles.

VW, BMW, and some others have also started including free maintenance for things like oil changes and wipers and brakes as part of the new car warranty.

On the flip side, I'm impressed your insurance is so cheap.
Sam's post has little to do with the emotion of "loving to drive."

It's a calculation about the cost of car ownership vs. taking alternative means of transportation.
I actually have some personal numbers after owning a second hand 2000 Mustang for 1 year from 112k to 121k miles exactly since yesterday. I got the car for 6000.

Uber 9000 miles x $2 = 18000
Personal Car: 7000
Maintenance 2500
- new bumper (old one taken off while street parked) 1000
- replaced foggy headlamps 400. purely cosmetic reasons
- side window smashed 800. never park in oakland =(
- oil changes etc? (200 at most)
Insurance 600 (checkout AAA)
Depreciation 2000(?)
Gas 1800 ($4/gallon @ 20 miles/gallon)

No contest for me, really. Even if I payed 300 bucks a month for a commuter parking spot in SF, and got an occasional parking ticket here and there.

For people who can get to and from work easily using public transportation, perhaps owning a car does not make sense as much as Zipcar/Uber. Owning a car can cost a lot of money, but for people who want one as a form of transportation it can be very affordable (i.e dont buy new). Also, the average car is expected to travel 10-12k miles a year.
