Return policies are per vendor. With eBay, it's almost too easy to get your money back and sellers take the hit when it isn't their fault.

In order of easiest returns: "Sold and shipped by Amazon" -> eBay -> Amazon 3rd party vendors.
It doesn't even have to be anything nefarious. For example just tracking network traffic (amount, not content) would be a good signal for a competitor (like Amazon) to monitor. If supplier A started getting a lot more network traffic from Walmart IP addresses and supplier B less, then that's a tell that someone could be interested in.
Like watching Silicon Valley
This doesn't make sense to me except as a marketing move.

For new items eBay's advantage is that you can buy in low volume straight from china (if you don't mind waiting a month) or from an importer who's running their operation out of a storage locker or basement. The prices are reflective of the decreased overhead compared to selling on Amazon (or some other "less flea-market like" option).

If you're shopping for something and don't want to wait for it to ship from China odds are you could already find it on eBay cheaper than Amazon in the first place.

This move is just publicizes and existing advantage.
PRO TIP eBay: people don't use your site not because of prices but because you are a horrible company to deal with.

“Works just fine” isn’t scalable
I agree with some of the other's comments that time is the most valuable asset. Be productive! Also:
1) Most of the advice that you find online is not really applicable. I like the stuff that Sam Altman (yes, ycombinator) puts out because it most mirrors what I've experienced.
2) You need to do it yourself. Whatever it is. Just do it.
3) Funding is a game. Here on the east coast investors pretty much only fund the growth stage of a company after you have real traction and are virtually guaranteed some kind of success. You will need to fund your startup out of your own pocket until then! This is what they call "friends and family" because you will be hitting them up for money, favors, meals, places to stay, etc.
4) The tech is the easy part, as that is what you know. Marketing and selling is the hard part, as that is what you likely don't know. It is the part you should try to get help with if you can, but finding someone that knows what their doing is tough, so you can be sidetracked quite a bit.
5) The "do things that don't scale" is completely true. Reaching out one-on-one has been the most successful way to engage potential customers, even though it is very time and labor intensive.

There are a lot of lessons to be learned here but I think one of the biggest to remember is - don't send any emails to anyone (even Mom) that you wouldn't want to be published on the front page of the NYT. Let alone to thousands of employees. For example, the yearly event emails that Travis sent from the frat-boy CEO frame of view. The employees probably received it well ahead of the event and likely even an uptick in morale, but in the long term, it is not an email he is proud of sending.

That's not usually the case. Boards normally operate on one-person-one-vote. A majority of the current sitting board members can therefore fire the CEO.

Shareholder meetings operate on one-(voting)-share-one-vote, so a majority shareholder ultimately controls the composition of the board. But if one of "his" directors, who his shares elected, breaks ranks and votes to fire him, simply owning the shares doesn't allow him to immediately override that vote. Kalanick could have voted out the board members opposed to him at the next shareholder meeting, and voted in sympathetic ones, who then might rehire him as CEO. But that's a different question than whether he could win any board vote simply by virtue of owning a majority of voting shares. Shares don't directly have board votes, they just elect directors who have board votes, who usually vote with the interests of the shares that elected them, but might not always. Besides exercising their personal judgment, directors also have independent legal responsibilities that may in some cases make it prudent for them to vote to fire even the person who put them on the board.

I don't use a taxi app in Budapest -- the good old phone dispatchers still work just fine and I almost never wait more than 10 minutes for a cab -- but in Berlin I use the "MyTaxi" app all the time[0].

The thing I find interesting is that MyTaxi is loosely coupled with the drivers. There is no obligation to pick up MyTaxi fares, you can go about your business as a cabbie and take MyTaxi fares when business is slow. Seems to work quite well for the drivers.

This morning I had to wait probably 15 minutes before a driver took my MyTaxi order, but considering how bad the phone-dispatch service is in Berlin I call that a win.

Everything else is very Uber-like: electronic receipt, pay in app if you like, tracking of the car on its way to you (more or less).

Oh, and two very neat features: you see your cabbie's full name (this feels safer to me) and you can save them, after rating, to a "favorite drivers" list, which I assume the service will use to help improve customer satisfaction.

> Don't we want companies to engage in price competition...?

The literature is mixed on the effects of price-matching guarantees [1][2]. The most compelling resolution I've read says "price-matching guarantees can facilitate monopoly pricing only if firms automatically match prices. If consumers must instead request refunds (thereby incurring hassle costs)...any increase in equilibrium prices due to firms’ price-matching policies will be small; often, no price increase can be supported" [3].

In any case, enforcing an automatic price-matching ban would be difficult. Would you prohibit firms from lowering their prices to match competitors'? If not, it would just take a few turns of the ratchet to send the message to would-be competitors (and consumers). Whether the consumer surplus from those ratchet turns are worth the enforcement cost is an open question.

No, content isn't that important.

AMD Vega's Shader Engines: Teraflops Unleashed for Gaming
I think the big error in A/B testing is that expectations are quite often very unrealistic. Designers typically have a reasonably good idea about what will work and what will not. Finding 'million dollar buttons' is rare. Of course a couple of percent or even 10's of percents of improvement is nothing to sneeze at. But thinking that by A/B testing forever you're going to make a shrub grow into a tree is imo not realistic. Aside from the detail that a continuously changing user interface is often in itself a barrier to sales.

Ironically, the companies that have benefited most from A/B testing were the ones that were doing a terrible job of it in the first place so then there is lots of low hanging fruit making the consultants look good.

Yet another item often missed: A/B testing success is a direct function of the length of the lever you are pulling. If that lever commands billions of dollars then it is easy to make it pay for itself. But if you're trying to turn $10000 into $11500 then you likely are wasting your time.
The basic system is pretty simple: just make sure the points you're tracking on the cloth don't move further than a certain distance away from each other. Doing it on the GPU is a bit tricky because you have to know which constraints you can check in parallel.

> "I really hope I can pay more to get from A to B", said nobody.

Oh, that's me! Here's a few reasons I'd want to have the option to pay a driver a bit more:

- I forced them to drive a stressful route

- I forced them to drive waaay off the beaten path

- They helped me schlep large items in/out of their vehicle

- I inconvenienced them somehow to where it makes their next ride a bit less likely to tip / star (like making a mess in the car)

> The market has spoken

A driver and I recently discussed this change, and our conclusion was: "finally!". Tipping is the custom in the USA for exactly this kind of job. Making it inconvenient or impossible to tip inside the app is like garnishing drivers' wages. Some drivers really really do deserve to benefit more from their labor, and some riders really do owe their drivers a bit more.

> Whoever gets there first, even in limited urban centers will win the taxi industry

Why "win"? There's no moat. I suppose there will be patents, but those expire or can be worked around.

More likely is that whoever gets there first will make all the mistakes that others can learn from. Every major car company has a self-drive effort now. Apparently Tesla, GM, Ford, and BMW are pretty far along. Lyft has a few partnerships here. It's only a matter of time before most cars drive themselves to some degree.

> It's not trendy or popular at the moment but asking somebody to write some simple code on a whiteboard is a really good indicator of whether or not they're a good programmer.

This again? This has been argued to death on HN. All the evidence points towards that type of interview having absolutely NO correlation to programming ability. It's also NOT what the author was talking about in TFA. He wasn't talking about general programming ability. He was talking specifically about data engineers who need to know how to do exactly what he was asking for on a daily basis. Notice nowhere in TFA did the author mention a whiteboard even once.
I mean, running a livery service in NYC is a fine business and there's no reason you couldn't make money at it. But it is certainly not the scale of ambition Uber was pitching.

It is my custom to use Amazon gift certificates at Coinstar machines to dispose of my extra coins, because in that case the coins are exchanged for free. (I have many extra coins, since I usually eschew credit cards.)

Wal-mart hosts many Coinstar machines, but I have yet to see one that will produce Amazon gift certificates. You have to go to Coinstars hosted at grocery stores for that. So, they have a contract with Coinstar that specifically mentions which firms may have gift certificates on Coinstar machines.

Who knows, this may be a boon for the grocery stores?
Regardless of what you're saying, Lyft lost $600M on $700M in revenue in 2016. Those numbers are awful. And worse than Uber. Lyft isn't in any better shape than Uber in terms of needing more funding almost every year to sustain the company.

Ask HN: Am I alone in not wanting websites to decide my specific fonts for me?
Anybody else here who doesn't like that sites have css with specific local font names first before specifying "sans" or "sans-serif" general families?

I like to think of myself as a power user who has spent considerable amount of time deciding which fonts I like as my serif/sans/mono fonts of choice and customizing them. I like seeing them when I'm reading stuff. Google does the right thing, not assuming a local font!

I hate it when some websites tell me which local font would work for me better. I can see if they're using a fancy font and loading from web but on my computer, I know better.

Why not just specify the family and be done?
