I think it's more the massive amount of spending they do with little to nothing to show for it. They spent $457m last year on autonomous and flying cars with $0 in revenue from those projects. Maybe that will work out, but I bet every penny was ultimately wasted.

Not spending billions a year on R&D certainly makes the financials look nicer. It might not attract as nice of a multiple, but it's not the ride prices that are out of whack at Uber IMO.
I heard on the news yesterday that 13% of all traffic in San Francisco is ride sharing vehicles, and that at any given time there are approximately 5700 ridesharing vehicles cruising around the city. Pretty stunning if you think about it.

The service also turned to total shit.

I took my first Uber in 2011. It was amazing. Expensive, to be sure, but the service was amazing. Black Sedan, extremely professional, shows up wherever you want, drops you off wherever you want, never really had to look at GPS. Just amazing.

It was so good I figured I'd never need car again. But it was expensive, so I used it sparingly. I'd take public transit or walk most of the time, but when I needed to get somewhere that didn't go or I needed to get somewhere fast, Uber was there.

Now it's a joke. A total joke. The service is shit. The base tier has people picking you up in minivans that rattle like they are about to fall apart and the people can barely drive… if they pick you up at all. There's like a 50/50 chance it will take 15 minutes for a pickup because the driver will go in the completely wrong direction and then cancel the ride. The "premium" service tiers come with fancier cars, but most driver still have no idea where they are going.

It was good when it was small. It was good when they only had professional drivers with carrier passenger permits and commercial insurance. It made sense. It was good for everyone. It was good when they actually had "drivers", not random people struggling to make minimum wage.

I also try to avoid it.
You also have to factor in gas, renting a parking space for the car at home AND at work, taxes, insurance, convenience, etc. It's one of those things like renting. Yeah, in the long run, purely financially, buying would probably be cheaper, but a lot more factors go into it in real life that doesn't make it as black and white. For me, not owning a car is still much better overall, currently.

Also, as I mentioned in another comment, it's just rides to work in the morning. I take public transportation home after work.
They filed for this in 2011.

According to https://en.wikipedia.org/wiki/Shadow_banning there is precedent from the 1980s, and Fogbugz had this feature in 2006. I don't know when Reddit implemented it, but by 2012 it was widely known that they did, so they may have implemented it first as well.

How was this patent granted?
When they first started out in my city they offered a ride pass that put a hard limit on rides less than 20 miles at $4. Yes, $4 for anywhere within 20 miles.

Then it was changed to $5. Then it was changed to $6, or instead you could UberPool for $2. Then they added a 2 minute waiting period for an UberPool. They then also changed the flat fare altogether and instead your ride pass came with something like 50% off all rides, with a maximum $6 discount.

It's obvious what would happen. At least my friends and I got it while the getting was good.
Is that a lot? I hear $5.2B is a lot...
"5 minutes of ads"

thats not the BBC then is it.
There was a delivery benefit. At the time we were one of the largest server manufactures by volume. Generally we were on the same scale as Dell or HP. Buying from only a single vendor had serious cost implications sure, but there was also a pure volume issues. If Intel can't get us 50k of a given chip fast enough we can fill capacity needs with an AMD platform instead. That was the goal at least.

> In Berlin, cannabis might get confiscated

That’s a very strong “might“. Possession is legal for up to 15g in Berlin, and virtually no cop will ever bother you for smoking weed.
FWIW, I don’t think self driving cars would have made them a good business. Once you no longer need drivers, all you’re doing is deploying a fleet of automobiles. We already have companies that do this: taxi services and auto rental companies. They’re shitty, low margin businesses with tons of competition. The promise of Uber was being a monopoly because they were first mover on a market with network effects. Much like eBay. But self driving cars remove the network effect inherent in needing to attract both drivers and riders.
I think what GitLab really needs is what a lot of open source projects are lacking: popular community forks. Their product development benefits from the community's QA feedback, but there are no community forks (that I am aware of) that are taking GitLab CE in directions that gitlab-org won't go. IO did this for Node and everyone has benefitted.

I think GitHub's UX has caused new developers to lose true meaning of fork. When software doesn't work the way you want it to, you fork it, and if other people want it enough, they will merge it into their own forks and maybe some day it will get adopted upstream.
Yeah, I take the bus/CTA home everyday, but still love my morning Uber rides. Haha Just so much easier, and I hate being all hot and sweaty from the bus or CTA when I get to work in the morning. ¯\_(ツ)_/¯
Remember that article yesterday about the company that resold movie tickets at a loss to gain market share? That's Uber's business model.

(Self driving cars were never going to save them. Not only do they not work yet, there's no reason to think they'd be much cheaper for years to come. Uber would have to pay for them, garage them, maintain them, operate control centers, etc. They'd be in the car rental business, which is not hugely profitable. Uber's business model is to dump their operating costs on their drivers. With self driving cars, they couldn't do that.)
How much is the total cost of owning a car in Chicago? Including gas, parking, insurance, maintenance and consumables, depreciation/lease, etc?
But then I’d be stuck buying software I couldn’t re-sell once I was done with it.

I’m also not the only driver and I like the idea of anyone borrowing it being able to pull codes at any time.
How would you do this? Remember, the chips in old apple batteries can be removed and used in other batteries.

As rides get more expensive or as these companies run lower on cash to burn; I suspect we'll eventually get back to the traffic reduction use case; an easy way to make a buck driving a route you're otherwise already taking or just a few miles from your house.
uProf is decent, but the instruction-based sampling approach is the only way to get pinpoint accuracy on instructions.

> I use ECC on a (consumer) Ryzen chip/board and edac-util seems to give me the same information that it does on Intel - what's missing?

Event-based sampling on Intel is accurate to an instruction-level (while event-based sampling on AMD is less accurate. You're forced to use the more complicated IBS metrics if you want instruction-level accuracy of events).

Intel also has branch-history data stored. Super useful for some developer tools, but I forget which tools those were...

-----------

I think AMD uProf is certainly usable. And the price is good (free). But Intel vTune is just light-years ahead.

AMD vs CUDA on the other hand is... closer than I think most people realize. CUDA has a bunch of libraries (Thrust, TensorFlow support, etc. etc.) which helps. But if you're doing high-performance coding, you'll likely have to write your own specialized data-structures. At least, that's the approach I'm doing with some GPU hobby code I'm writing.

TensorFlow (due to Tensorcores) and BLAS are solidly NVidia advantages. But general purpose libraries (ex: Thrust) is more of a convenience.

AMD's main disadvantage is documentation. But the tools are actually quite usable. AMD documents the lowest level well (the ISA), but their HIP / HCC / etc. etc. documents are lacking and difficult for beginners to follow.

AMD should work on updating their beginner guides (their OpenCL guides) to their ROCm framework. Even if its ROCm OpenCL 2.0 stuff, its important to get beginners to use their platform. Or at least, update their beginner guides to reference GPUs that have come out within the past 5 years...
I used to commute from San Mateo to San Francisco on Uber Pool for ~$10 each way. Same service is >$20 now.
YC-funded SFOX launches tool tracking data on every crypto trade in real time
In my case, since nobody else has replied with public transit: SF has a really great bus system that, if you're traveling along any of the frequent lines with bus lanes, is usually the same speed as an uber once you factor in the wait. It's just $2.50 for 3 hours of free transfers, and 24/7 service.
This. If you're commuting 1-2 hours this is a hit on your income...i think most don't realize this. Downtown toronto is worth it depending on your goal.
I think what he is saying is the demand for Lyft / Uber was manufactured by low prices. Now that they are more expensive, people are using public transit more.
Ah thank you - yea it might not be directly coming out of the company as a cash expense but it certainly is depreciating the value of the company and considering that stock options of various types are often offered to supplement salaries (and let's just understand that nobody gives up money for free, so were these options not available they'd be paying higher labour costs) then it is logically an expense to the company by way of dilution to actually carry out their disbursement.

I am pretty personally wary of stock based compensation in non-publicly traded companies since it's a gamble that the employee is accepting that is entirely controlled by the company - bad business decisions can cut your compensation through no fault of your own if the company goes bankrupt.
The economics can be interesting. For me to own a car means I have to pay $300/month anyways, just to be able to park it in my apartment building. After considering the cost of ownership (insurance, maintenance, gas, etc), I decided it wasn't worth it.
Also in Colorado here! I got an "All Season Solar Cooker" - plenty of Youtube videos showing it and other options in action. I also just finished making a toy solar oven made from cardboard, aluminum foil and seran wrap. It gets up to around 165F in strong sunlight. When I build a real oven made from wood, mirrors and glass, I think it will reach about 350F. I'm going to keep experimenting with toy designs before building something more substantial. I'd like to have multiple solar cookers and ovens to be able to cook several dishes at a time.

For the solar cooker I prefer to put the cooking pan inside some pyrex dishes. This acts like a greenhouse and limits the wind's ability to blow heat away. It gets very hot, but not as hot as a solar oven. Hot enough to bake bread!

That mortgage has to be paid.
You can get a lease on something like a Toyota Corolla with no money down and ~$250 per month. That plus gas plus maybe having to pay for a parking space would probably break even, if not save a little money. Not to mention any rides that aren't part of the commute.
> Keynes never argued in favor of stimulus at times like these.

Further: He argued for austerity at times like these, so that the budget would balance over the whole cycle. That idea has far more restraint and fiscal conservatism in it than either party has shown in decades.

One could argue that, with interest rates this low, borrowing to work on infrastructure makes sense. That may be a reasonable thing to do, but it's not a Keynesian policy (because we're at the wrong point in the business cycle).
I never paid for a license. It's insane to be forced to subscribe to a handful of channels you may or may not be interested in.

The "inspectors" have no legal right to enter your property, so you can simply tell them to fuck off.
I know it's anecdotal and people live their own experience, but in my own experience dang is the only moderator I can recall having a conversation with where it WAS a conversation and not some authoritarian declaration. He even seems to go out of his way in comments to explain his thoughts and I have seen him change his mind and admit things as well. I wasn't aware he was Canadian but it funnily feeds the positive stereotype of politeness in our northern neighbors. Most people in positions of power online seem to be little Joffrey types with take it or leave it attitudes regardless of how you speak to them.

Also add me to the people who didn't know it was "Dan G" for the longest time and loved "dang" as a name.
Exactly. It’s just an expense that you get to ignore for the time being because it doesn’t affect cash flow.
If you can get any light fluctuation reading at all from the room, you could correlate that with the live channel broadcast and get a match.
> People were willing to pay taxi rates all along

Baloney. The market size of people willing to pay taxi rates for transportation is much smaller that the market sizes currently implied by Uber and Lyft's valuation. Before Uber and Lyft, most people I know would only take taxis very occasionally, for special occasions or emergencies. Once Uber and Lyft started offering such good rates they would use ride sharing much more often.
Parking spaces at both at home and work can easily be more than that in a major city. That is more limiting than even the car costs.
Subtly different situation -- a dog sniff is only an indicator of probable cause, while a breathalyzer may be presented as evidence of guilt.
As a personal hacking project in my spare time, I switched from T-Mobile to anveo and an asterisk setup. I can send and receive SMS on my server and can make WiFi calls on my phone. SMS gets sent to my email as well. This costs maybe $45 USD a year. I've thought about documenting my setup but I don't know if there is any interest.
We cord cut and moved away from broadcast TV round about 2000, or a little earlier, yet retained a TV. It was far, far easier to get the BBC to see sense about licence status - either not needing one, or having one and they simply messed up details on moving or whatever, than it has been with Crapita. Since the BBC were forced to outsource it, in the early 00s, we found it simply wasn't worth bothering with. They were getting it wrong about our status over 50% of the time, despite following their "prove your innocence" hoops every year or two on the website, often the same day the letter or email was received.

Eventually we gave up and just let them inundate our paper recycling. They've been comically useless. I am certain after 15 years of their incompetence, Capita have been responsible for many an unsafe conviction.
And also sometimes they sue, like with Amazon's 1 Click Checkout.

I think HN takes a pragmatic approach. There is quality news on those paywalled sites. They are paywalled because they need to pay professionals to write quality researched content (it isn’t some internet marketer trying to make a quick buck) so ethically it seems OK and there are workarounds.

I think there would be a natural balance in that a paywalled article needs to be even better than average to do well as fewer people can read it to upvote it. So hopefully when a paywalled article appears it’s better than average.

Medium.com is my only concern because they paywall run of the mill blog quality articles. I’d encourage people to post using a friends link in that case if they can get it.
Ah, you're right. I imagine most users aren't aware of this because they assume that if their comment was removed, they would see the "[removed]" tag like they see for everyone else's removed comments.

And either many redditors have never had their comments removed, or more likely, shadowbanning is apparently a lot more effective than people realized.
I've had 4 battery replacements and Apple has never done anything other than exchange the whole phone.

On the other hand, they spent $0.5 billion on R&D in a year, and lost $5 billion in a quarter, so I don’t think the R&D is nearly as significant an issue as subsidizing rides.
Just a guess: maybe Apple is locking iPhone batteries because the anti-fix-it negativity is less expensive than battery explosion lawsuits?
That's fucked up, I'm sorry. In most places in the US, cops would ignore it, because it doesn't do anything. Breathalyzers detect metabolized alcohol vapor from your lungs; nothing you can put in your mouth will stop that as long as there's alcohol in your bloodstream and you're still breathing.
I remember exactly where I was when I first heard NPR tell listeners they could visit "their FB" or follow them On Twitter in 2010. I got a visceral bad feeling.

In the 90s, the prevailing wisdom was not to disclose personal info on the internet because it was understood that "the IP stack" was designed with maximum liberty and tolerance for all kinds of garbage (with personal tools to filter, and the assumption of personal responsibility). Comparing the dynamics of Usenet vs. FB is quite revealing and brings insight into the discussion about distributed vs. centralized power. We've dumbed everything down to the point of ridiculousness.
I happen to like a large printed map, and they do support it in the hamburger menu. The result is unusable though. I dont have a data plan, but I'll look into the latest OSM which has directions.
Mainframe operating systems have had a database integrated in the OS for a long time.

https://en.wikipedia.org/wiki/Virtual_Storage_Access_Method

A VSAM table is like one table of a SQLLite database but it done in the OS rather than userspace.

I also believe that the 'CATALOG' that indexes all of the files on a filesystem is itself a VSAM table that works a lot like the master file table on NTFS.

So far as embedding folders and other files in a document, the foundation is already there. Microsoft Office documents are already ZIP files that contain XML files for the primary content and have embedded images and other media files.

Also from the Microsoft world, the Registry is a configuration database built in to the OS which works better than text files if you have a GUI for configuration.
I suspect the larger the prize and potential to succeed to get it, the more one will be willing to spend to get it.

Actually my conclusion was the opposite, but thanks for undermining me.
Maybe people like the listicle format because it promises to be quickly digested.

Actually, I wonder if it even needs to be a list. I think a headline like "Economics explained in 20 words" would be attractive in the same way. If it was 100 words, I doubt it would work as well, even though both headlines would be obviously absurd.

What's going on, there?
...Uber when it first started was a Black Car service... you can still call a black car service and it will be a certified livery driver.

There are also still plenty of black car services around if you are concerned about loss of quality in more affordable offerings (where did you think the tradeoff was going to be for a more affordable solution? Purely scale?)
I doubt they would be. Even laptop battery BMS systems brick themselves so they can't be reused. It's where I get all my 18650's from. They are all NOS batteries that were never used and the BMS disconnected the cells due to fractionally too low voltage. Cells are fine but the BMS chip will never work again.
It is actually worse than this. They send out the letters (it often seems randomly) AND they will send someone to come to your house who will "inspect" your TV/demand entry/make threats...

...this is one of these utterly bizarre public sector things where the govt will hire a private company to chase down people (usually immigrants, unemployed, etc.) and give them a cut of whatever is looted...unsurprisingly, this has proved to be controversial in practice.

I have actually heard of people who called the police because they were being harassed by these people. All so some chinless wonder from Oxbridge can get paid £200k/year commissioning dogshit documentaries about Ethiopian trance music (the BBC massively underpays for talent but employs an unfathomably large number of middle managers).

I would love to see how this kind of system would work in Texas.
Dilution of ownership goes in two directions. You pointed out that it could be less valuable than the book value. But if the company does well, then the cost of that dilution actually increases over time.
It's generally much more helpful to say what's correct than what's wrong, if only because there are so many more ways to be wrong.
Often when I see lists of "myths", the "myths" are true or close enough most of the time, and are only harmfully wrong in rare circumstances. Getting rid of a flawed but workable model without having a better one to replace it with is not an improvement.
They already have an app for hailing cars, viewing their status on a map, etc. which tons of people already have on their phones, as well as an extremely recognizable brand and lots of data-center investment to back it all. Competitors would pop up, but don't underestimate the value of those things.
What kind of context are you looking for? What audience? Is a book the only option?

In general, people learn from presentation of material, participation to demonstrate understanding, and then receiving feedback. They need to be motivated and engaged. If you're asking how I would suggest someone self-learn something, I would suggest that they find a cool project that they're excited by, and then offer resources based on that. Ideally ones with interactive feedback and tons of examples.
