I'm staying for a while in China (Beijing), and signed up for Ofo. Unfortunately, I didn't know that they have quite a bad reputation. About 1/3 of the bikes are broken, and nobody bothers to collect or repair them.

More worrisome is that they seem to have an unsustainable business model. At signup you pay 99 RMB (for Mobike it is 299 I think), and they you should pay per ride - but I've only once had to pay at all, most of the time it is 0 RMB. I guess that's also why they don't care that much what happens with their bikes. Their only income is new sign-ups.

By the way, the latest Ofos also have digital locks, and even Bluetooth. And there is a new generation of MoBikes I think which is a lot lighter. It is interesting what kind of new technologies MoBike uses, like airless wheels, where the tires look like swiss cheese from the side to save weight and roll lighter. Or a chainless drive.

About the stealing, I have the opposite experience. I think Ofo has proven that you can just slap a combination lock on a bike, and honesty or laziness will keep people from stealing them. I mean, where would you store the stolen bike? In front of your house, where there are hundreds of other Ofo bikes that cost next to nothing?
This was almost 7 years ago and I sold the company in less than a year of operation. It wasn't like retirement money though, got about a year of break from work. I've launched a few startups after that and joined a couple other startups in the process. But nowadays, I just try to do consultant gigs. Looking back, I still can't get over how great it was though and I regret selling it too early. I also realized just how hard it is to launch a successful business and I was pretty lucky with my first.
So, MoBikes don't get stolen? Why? Is the GPS System so hard to remove or are they to inconvenient to use as a stolen bike? (Weight is 17-25 kg)
Cost should not be an excuse at the expense of safety. Plain and simple.

And if you for some reason want to participate in chat, there is irc.twitch.tv, where you can simply join channel #streamname in IRC client of your choice, again without all the web crap, and without all the inane twitch emotes.

I've been doing that for a few years now, much more pleasant experience than their web interface.

I usually avoid making comments like this, but I'm surprised I had to go down so far to find a mention of Uber's existing tip culture. It's far better for passengers for tipping to be app integrated, and thus optional with less pressure from the driver, rather than Uber's prior system which resulted in many drivers effectively begging for cash tips.
"most of the time it is 0 RMB"

This is true. I don't understand why. I thought it may be a first month freeby or something.

It's not just public perception - it's internal perception too. Attrition at Uber is through the roof. Yeah, Travis is one of the best people for the job and his aggressiveness built Uber, but you can't build and maintain Uber if the rest of your talent is fleeing and you can't replace them because of your rep. Plus, he's obviously created a lot of liabilities for Uber at the same time that he's created value - besides the massive cultural problems, Uber's facing a number of dangerous lawsuits.

Quote from the link above:

Gaode map traffic data show that driving users within 5 km of travel accounted for more than 30%, travel accounted for the largest proportion. From the shared bicycle travel mileage data, more than 90% of the shared bicycle travel scene concentrated in less than 5 km, which shows a short distance travel, sharing the bike instead of driving a large potential.

Compared with the first quarter of last year, first-tier cities driving users within 5 km of short-distance travel accounted for has been reduced and relatively obvious decline in Beijing, driving within 5 km by 3.8%, Shanghai 3.2% reduction, this phenomenon may be associated with the emergence of shared bicycles A short distance driving trip.
Huh, neat. This is really similar to the underlying mechanism used in the compiler that only used x86 mov instructions.

I used to never tip. I thought of tipping as a review of their work. Good service:18% ok service:10% crappy service: lousy tip.

Then i got displaced. Bartending introduced me to the tipping "infrastructure" and lifestyle.

Then making deliveries.

I think developers just can't feel until my way about tipping until they lose their jobs.

It is not they are assholes - just not worldly.

Classic engineering ethics problem. Management says they have to ship "right now", but you know that if you do, 1 in a 1000 customers will die. If you wait a couple years, that'll go down to 1 in 1000000, but your company might go bankrupt.

Engineers at Takata and in GM's ignition key department made one choice, Waymo seems to be making the other.

a bit offtopic but -- imo technical folks don't need MBAs. However you _do_ need a person who can sell. That person might have a technical background, might happen to have a MBA (though frankly very few MBA types are very good salespeople), but honestly the skill is orthogonal to anything else.

The question you ask an engineer is "can you build this?". The question you ask a business cofounder is "can you sell this?"
What's unsafe about radar cruise plus lane keep? People act like Tesla is shipping cars that fling themselves into pedestrians at every opportunity. Somehow we all manage to absolve the auto maker when someone with cruise control set on their 1998 Mazda rear ends someone on the freeway. Let's judge Tesla for autonomous safety when they produce an autonomous car.
he could have cleaned ship years ago with all the previous scandals but he was either too stubborn or too arrogant to think any bad news would pull his company down. he was representative of uber's toxic culture and it seems like he should have stepped down right after he was caught bad mouthing a driver FROM HIS OWN COMPANY.
> the manufacturer building those bikes are making less than 1.5 USD per bike

That sounds like stupidity on side of the bicycle manufacturers. I've heard anecdotally the opposite, that the new ride sharing schemes have revitalized the bicycle industry.

I was in Beijing 4 years ago, and all of the famous bicycles were gone. The bicycle lanes were used for cars. Now they cleared the lanes again, and people are riding.

I'm not sure the current details are sustainable, but the idea in general has potential to be a game changer.
Ask HN: How to market large scale open source hosting?
TL;DR How to market www.datacenterlight.ch non intrusively to Open Source hackers?

Hello,

here is Nico, FOSS hacker and CEO of ungleich.ch, a small Swiss Open Source company.

We have the Swiss wide unique possibility to offer really affordable VM hosting in the midst of the mountains of Switzerland, because we can host our servers in old factory halls.

Thus we save a lot of energy and money and want to give this price advantage to our customers.

We love that our software stack is 100% open source, running with locally produced water power and omitting active cooling (because it is cold enough).

That said, with our low margin want to address a substantial amount of customers and mainly those who love Open Source like we do.

Running a browser with adblocker myself and hating unsolicited advertising, blinky gifs, etc. I wonder about your opinion:

How do you think we should market our product?
recycling is just a small part of the story. all those bikes are basically un-managed. that is actually the core strategy to minimise operational costs.

the real question that need to be asked here is - if I need to pay for parking my car on street, how can those two multi billion business[1] enjoy such privilege to park their 10 million revenue generating bikes on streets for free.

Uber needs the network effect. Lower usage means fewer uber drivers, which means it's harder for me to get a lift, which makes me use something else. So a relatively small dip can cause a collapse un usage.
> Completely ridiculous. The model was not to raise rates in the future.

I'm not sure if you're disputing OP's idea that Uber subsidizing rides is (at least in part) of an effort to kill the taxi industry, but my logic is, if you don't have any competition, why wouldn't you raise rates?

Types checked at compile time is called "static".

Strong has various meanings. Ada is "strong" versus C being "weak" though the basic Algol-like model is not so different, and if we don't count tagged types, neither language is dynamically typed in any way. (So if "strong" means "static", we would not be able to use the strong/weak terminology to contrast these languages!)

"Strong" in this context mean various things, ranging from C having holes in the type system that allow punning and bad memory references, to C having automatic conversions that are unsafe: for instance assigning a floating-point value to an integer location without an explicit conversion operator which handles situations when the conversion is impossible. Or not having a character type distinguished from an integer type.

C++ has more "strongly typed" enums than C; and what that means is that you can't assign an integer value to an enum object without a cast.

ANSI Lisp is fairly strong, but allows some relaxations: car on an empty list, integers usable where floating-point values expected (a bit like C) and such.
Hate to break it to you but those drivers were talking to you because they want you to rate them well, and there is a financial penalty if they didn't talk and you rated them poorly.
I don't agree it's quite that uplifiting. The culture had to be absolutely horrible, all the way up to the top, for Fowler's story to have an impact. Uber was already gearing up their lawyers against her, and if their culture hadn't been so pervasive, and if there weren't a series of other contraversies at the same time, things might have ended poorly for her.
I'm curious how much Kalanick has already taken off the table. That may be a motivating factor in his decision. If he has already pocketed hundreds of millions, he may understand that this could well be the death of the company, but just isn't motivated enough to fight these investors and is willing to let them burn the company to the ground. I wouldn't go as far as to say he doesn't care anymore, but being forced out of your job and the potential evaporation of billions in paper wealth isn't such a catastrophe if you already have enough money for several lifetimes in the bank.

I think the actual reason why it failed was that it was not Ubuntu at all. When I got mine, I expected to be able to apt-get install everything. The form factor may have been wrong and uncomfortable, but from day 1 I would have access to thousands of applications I was familiar with. I also expected convergence from the start.

It turned out to be a completely separate ecosystem that started from scratch. So, there would be no actual advantage in having the Ubuntu name on it. It was just a marketing move, but it had nothing in common with the Ubuntu I know from the desktop

The veteran knows that equity is something you can negotiate hard for and is very negotiable.

Regarding equity comp for early hires, presumably the founders have already done significant derisking by finding initial product market fit, secured initial capital, built a prototype, have buyer interest/commitments, etc.

Every time I see complaints about single digit % compensation, I wonder how many of the people complaining will go out and actually put in the work of validating a market and getting the initial momentum for sales and meeting 100 "investors" and "pseudoinvestors", put in years of networking to even be loosely connected to the money network, getting 90 rejections to get your first $500k, and the shitwork of setting up a corporation and doing all this work out of pocket in exchange for 10x the equity. I mean literally no one is stopping you from setting up a company that you own 100% of the equity of.

Is there an available API/service that does the trip tracking part of Uber? Of any technical challenge that would present a bunch of clones popping up, I can see that being one of them. The rest is just generating an invoice and accepting a credit card payment. Obviously, not to scale, but for small-medium-sized locales, it could suffice.
If they are talking about "direct primary care", then there are still plenty to choose from: http://www.dpcfrontier.com/mapper/
It will also be a tragedy. With Kalanick gone, Uber is already behaving like a conformist, viz. the recent headlines (1) "Uber co-founder: We’ve been too obsessed with growth" (what?); (2) "Uber is (finally) rolling out tipping" (just awful). That sounds just like Lyft and Lyft is not a worthy rival in any sense of the word.
How I feel is irrelevant. Consumers and investors feel that Uber behaved immorally, and there's some indication that the legal system will agree.
The board lacked the power to fire him. He controls most of the company. They had persuasive power, sure. But if he had wanted to dig in and refuse to leave, he could have.
As far as I know, no car manufacturer ships cars equipped with LIDAR. Nor do they seem to have a camera setup as extensive as Tesla. So I fail to see how Tesla has painted itself into a corner. The worst case is, that they are not reaching full autonomy with the current hardware setup. It certainly would be a big marketing blunder if they don't, but if necessary they can add LIDAR to the production, if they choose to.
Not sure what could be a scalar scatter/gather, but NV and AMD GPUs do the vector one (you can read write n values from n offsets with a single instruction).
What are you talking about? They have 100% coverage for all streets on both planets.

I'm not sure how to feel about it too. While I will be tipping (when actually using Uber), after I initially wondered why Uber didn't allow tips I concluded that the drivers could become unfriendly about it. They are not yet aggressive about ratings here (South Africa), but I've heard horror stories from the US.

I agree completely. Not only woulld this all go away if they are paid better, but they would likely be more motivated and friendly.
I think this is right on. It's a crucial moment for Uber and that is no time to hand leadership off to a big committee.

I'm seeing a bunch of references in these comments to when Steve Jobs was fired from Apple.[1] A more relevant reference might be when Jobs stepped down to treat his cancer. He named one interim CEO--Tim Cook--and fully empowered him to run Apple.

If it was Travis's idea to leave a 10-person committee in charge, that is the sort of insecure, bad decision that would set off investor alarm bells.

[1] This is actually not a great comparison to Travis. Jobs was not CEO when Sculley fired him, and in fact had never been CEO of Apple. He was one of 3 founders, each of whom was arguably crucial to the early success of Apple--Jobs, Woz, and Mike Markkula, who did serve as CEO and sided with Sculley in firing Jobs. Apple subsequently grew 10x under Sculley.
Perception is the same as reality here, though. He could be a great leader, but still too controversial to keep at the company. If it wasn't an organizational decision, it was a marketing decision.
Tesla didn't have to ship a car with unusable self-driving hardware. They'll probably have to eat the cost of a retrofit package on some vehicles to make that work. Like the Roadster transmission problem, where they had to replace all the early drivetrains with the two-speed transmission.

Nobody has built automotive LIDAR units in volume yet. That's why they're so expensive. It's not an inherently expensive technology once someone is ready to order a million units. It does take custom silicon. Tesla, at 25K units per quarter, may not be big enough to start that market.

Continental, which is a very large auto parts maker in Germany, has demo units of their flash LIDAR. They plan to ship in quantity in 2020. Custom ASICs have to be designed and fabbed to get the price down.[1]

Kara Swisher's podcast had an excellent episode on Uber that did a great job surveying this firestorm, and defending Travis' business direction, without exonerating his leadership's many flaws. Definitely worth a listen.
One possibility, because increased rates could result in your user base using your service less often?

While transportation is something everyone needs, I'm (as priviledged as I am in my salary) not going to pay $20 for an uber if it's $2 on the bus.

I'll take uber when it's $10, compared to $2.

They could possibly raise their rates some, but to answer your question specifically: because there are other factors involved in their price/demand/profit/market share equation, besides just competition.
