> This gross oversight in the overengineered (especially for its time) MPEG-PS and MPEG-TS container formats just leaves me dumbfounded. If anybody knows why the MPEG standard doesn't just provide a byte size in the header of each frame or even just a FRAME_END code, or if you have a solution for this problem, let me know!

Because the video encoding was created in 1988 and the mux format in 1995 when large amounts of fast RAM were incredibly expensive and recording/transcoding and processing devices didn't always even have a framebuffer to store a full frame. Many many MPEG-1, MPEG-2 and even MPEG4 AVC Baseline limitations become very obvious when you consider that they were encoded on CPUs that might be slower than 150MHz and be decoded on devices which may only have a few macroblocks worth of storage for decoded frame.

> Interestingly, if I interpret the source correctly, ffmpeg chose the second option (waiting for the next PICTURE_START_CODE) even for the MPEG-TS container format, which is meant for streaming. So demuxing MPEG-TS with ffmpeg always introduces a frame of latency.

I think the confusion here is because MPEG-TS was created for broadcast TV streaming, not realtime streaming. Broadcast TV can easily be seconds behind the source these days and has probably travelled at least once from geostationary orbit so one frame really isn't something anyone cares about. The more modern HLS/DASH formats tend to be even worse at this, with many sources waiting for a full several-second long chunk to be complete before transmitting it to the viewer's device.
Here is one of my favourite "myth list" articles: https://www.seriouseats.com/2013/06/the-food-lab-7-old-wives...

I think the form fits great with the content. So it can work, but the myths listed have to actually be widely held and promulgated false beliefs.
Indeed. But I'm not sure that makes it 'anachronistic'. More that some places are, well, more dangerous.

On both sides there's a bit of eyeballing I reckon.

At a rest stop you can often chat to hitchhikers before they even know you have a car.

It wouldn't surprise me that in the US (particularly around major cities) hitchhiking is considered dangerous because, well, the US has severe issues with mentally unwell individuals on a scale that simply isn't present in other cities (e.g. the people who have basically fallen out of society you'll see on SF/NY subways; not merely homeless but severely mentally ill).

I would guess without having been there that hitchhiking in the more rural states would be fine.
IMO, the idea that fully self-driving cars are anywhere close to being created was always just a combination of hype and wildly irrational underestimation of how hard it is to create them. The challenge of building a road-safe fully self-driving car is not far from the challenge of building artificial general intelligence. I think that road-ready fully self-driving cars are many decades away, and they may never actually be created.

What really surprises me is how many otherwise savvy and tech-knowledgeable people bought into the hype.

That said, I also think that not everyone involved in spreading the hype does it for innocent reasons. For example, people often criticize Elon Musk for making absurd claims about self-driving cars, but then argue that he does it because he is innocently deluded. I suspect it's more likely that he is lying through his teeth.
Very relevant. To be honest I'm surprised that TV licensing haven't worked out how this fellow is and added a special exception so he doesn't receive their silly letters.
This is a great piece about Uber/Lyft. https://americanaffairsjournal.org/2019/05/ubers-path-of-des...
Quite interested!
>Uber is not a real business. Nothing about hiring a driver or maintaining or running a car is cheaper now than before Uber.

It's even worse, outsourcing maintenance, insurance, upkeep and whatnot to individuals is on the aggregate more expensive and time consuming than having a division of labour and a company who can manage these costs in bulk.
I hope they don't actually think that. Autonomous vehicles will turn a two sided market into a one sided market. Just think about all the companies working on self driving cars that don't currently compete with Uber. As soon as they succeed, they'll build an app, buy thousands of cars, and cut the per ride price to nothing.
I must admit I never noticed that! Apparently I don't downvote often.

The more you know - Thanks!
And how many trips do you take with your car (so we can calculate the cost for replacing it with an Uber)?

By who? Do you seriously read an HN comment that states something you didn't already know with a citation you don't bother to click and then just go forward assuming it's scientific fact?

I don't even take publications themselves as scientific facts until they have been reliably reproduced or provide ample evidence.

I think the issue investors had was the growth rate slowing and misses on revenue.

You can see the losses shrunk (lets for just a second ignore the stock based compensation because that should have been something every investor of Uber should have known was coming) but missing on top line revenue is pretty rough.
I rarely took taxis because of the cost. Uber and Lyft value is their price and the ease of getting a ride. However, as we know, this is not a sustainable model (Extremely discount rides.).

Kinda sucks to see as I think the idea of the service is good.
The only way they survive as such a richly valued company perhaps, my point is they could provide the current level of service with vastly lower spending and be a sustainable company. The financial problems aren't they charge too little for rides, it's that they have thousands of people working on bullshit that brings in little to nothing.
"Falsehoods programmers believe" tend to be implicit assumptions people have, while "myths" tend to be deliberately propagated ideas.

Reciprocity is one of the mechanisms people use to part you with your money. Sellers use it, charity uses it, scammers use it. No wonder that people tend to dial down their reciprocity if they can.
> Nothing about hiring a driver or maintaining or running a car is cheaper now than before Uber.

Uber can use better scheduling algorithms to ensure higher utilization factor of their fleet. If a taxi driver is driving 50% of the time and waiting for a fare other 50%, while Uber driver is driving 90% of the time and waiting 10%, the price for Uber ride could be lower while ensuring the same income level for the driver.
I'm not sure I understand? The service I built is entirely WiFi based. I find most bars restaurants and coffee shops generally have WiFi capable of VoIP traffic.

> Could you clarify why you thought this?

I learnt of the news about 8chan from this thread: https://news.ycombinator.com/item?id=20616055 — which was on the HN’s first page before it was replaced by the slightly longer thread you linked to. The top comment in that thread is decidedly against the chans.

There’s also been a lot of mentioning of Popper and his paradox of intolerance in these threads. A post [1] in the thread you referred to (it also was among the top ones when that thread appeared on the front page), for example, began by saying that "Popper taught us that we can't be tolerant towards intolerants" ("taught us" implying that this statement has grown to become general wisdom).

If HN’s prevailing sentiment has since turned in favor of 8chan, I am very happy to hear that.

Wow I had no idea it was that low. No wonder people wants that product. Here a uber ride is the same price as taxi (because it is taxi) so 15 minutes is easily $50.

Is that really the case in the US?

At least in Germany, my standard way of getting a cab (wherever I want) was calling one of the dispatch centres.

Taxi-hailing apps made this slightly more convenient, and displaying the cab's route to you removed some stress, but it didn't fundamentally alter the service.

And Uber really doesn't add any value except for undercutting prices by subsidising the rides via investors and shovelling risk etc. onto the drivers.
I'm pretty positive that is Google's end goal. They even had (have?) and integration with Lyft/Uber at one point so that you could hail a ride from within the Google Maps app. My bet is that it was meant to be a proof-of-concept to see how hard it would be just to replace them with their own service.
I was shaking my head in disagreement, until I read:

> If we were to have truly political discussions, we'll need to include all the other countries of the world, which none of us would want

That's a really, really good point, and I'll keep it in mind when political topics arise.
I'm a bit confused by the sudo tag; it seems to imply that commands run with sudo get elevated privileges... which is kinda the point...
It's also possible that the distribution schedule and reimbursement formula for every big Disney film released so far was signed prior to the announcement of AList (barely a year old), and those contracts have no concept of film subscriptions, which is where AMC is trying to fill in the blank with a lowball number.

If the studios were happy, they wouldn't signal uncertainty and dissatisfaction to investors by bitching to the Wall Street Journal. That can only negatively affect all parties.

Is it? TF2.0 Alpha and Beta release notes don't mention anything about it, and the official docs at https://www.tensorflow.org/install/pip are quite explicit that the tensorflow-gpu supports only CUDA cards.

The last time I looked at ROCm (which was something like a year ago) it was "supported" as in "there's reports on the internet that someone got it to work" but when I tried, I couldn't get it to work and it really wasn't worth the effort. If I'd dig out a machine with an AMD GPU right now, can I get it working (like, train MNIST or some other helloworld'y system) within an hour, and is there documentation available on how exactly that should be done?
What happened to personal responsibility? Is that out the window as well? Or do we need intervention, similar to how parents point their kids in the proper direction to go?
Except Taxi services were at least reasonably well regulated and had award wages, including vacation and sick leave (Australia) and now people work for less than minimum wage and have jack shit entitlements, can be terminated at will.

Same goes for many other gig economy roles.

>I like to compare them to the car sharing companies (like zipcar/car2go etc...) which managed to de-throne the entrenched rental agencies without going out of their way to break laws.

Except for the fact that Avis bought Zipcar. So not sure about the dethroning part.

I know some folks who really depend on short-term rentals to support being carless but it's a relatively niche service--especially with current Uber/Lyft pricing.

Uber and Lyft did the hard work of making ride-sharing mainstream, but there's really very little they have to offer other than name recognition) over any other player that tries to enter this play. I still strongly believe that some aggregating service like Expedia, Travelocity or Kayak for ride sharing the treats Uber, Lyft or any other player in the market as the equivalent of an airline would work fine in the vast majority of cases.

That, and I firmly believe Uber still deserves to be punished for its past bad behavior on so many fronts. I used to feel for the people working there that didn't contribute to the problem, and worry that any punishment too draconian would hurt them, but Uber got away with stuff so bad for so long, that I think anyone that didn't vote with their conscience and try to find somewhere else to work was taking a calculated risk, and it's not a risk if there's no chance of a negative outcome, so they reap what they sow. Anyone that didn't make the choice to leave ended up contributing to the problem by allowing Uber to ignore the consequences.

We have gone well beyond the message I wanted to convey. But for the sake of XKCD:386, let me dig a little further in this hole.

You have just described two different things, with different names and different logics. The results of running both is the same but the two are not the same thing.

Moderators sharing lists of usernames to ban versus the software itself banning users globally is not the same thing either. Again, the result is similar, but the process and logic are different.

It is important to make a clear distinction between similar processes.

But yes, you're right, the results are identical and most users will not see the difference.
> as possible in catastrophic situations

That isn't really something engineers can design to. What happens is the aerodynamics group calculates the maximum loads on the airplane. This is increased by 50% and called the "ultimate load", and the parts are all designed to not break up to that load.

Parts stronger than that are overweight, and weight is the enemy of all airplanes.

After parts are designed, they go through an independent "stress" group which verifies that the parts meet the strength requirements.
I apologize for my snark! You're right, and thank you for releasing this open source :)

I disagree. Expense was never really an issue for me.

My issue was always summoning the taxi. I was generally operating in secondary markets like Las Vegas off-strip, San Diego, or Pittsburgh. You couldn't schedule your trip to the airport because you never knew when the stupid taxi would show up.

While I hate many things about Uber/Lyft/ridesharing, they changed the customer service expectation of the whole field. Even if the prices go back to taxi levels, that's a massive improvement.

In a weird way, if you don’t work for those companies it’s basically that billionaires are subsidizing you.

I agree 100%, perhaps I could have phrased that better. I try to use it as a teachable moment: "Hey, instead of using base64decode.org did you know you could use atob and btoa in a web inspector?"

Security-related scanners are a tough one though. Free XSS scanners, free TLS cert checkers: The best intentions can result in unintended disclosure. Developers have it constantly beaten into their head "Security! Security!

This seems like a good place to ask the question: how is it that we're seeing $15T of bonds worldwide trading with negative yields? [1]

TFA suggests this is due to structural factors--institutions that are required by law to own AA/AAA bonds. Is this some deficiency in the law or corporate governance, that cash in this circumstance isn't considered a substitute for a negative-yield bond? Its net present value would be greater. I can't imagine a scenario in which you would come out financially ahead from owning a negative yielding bond instead of cash.

I'm not sure having a easy link is necessarily a good thing.

This is the similar effect to having google maps vs. looking up direction before driving on remembering your route.

The PS4 is an example of that. It's an APU with GDDR5 acting as both system and video memory.

To be honest for a while I thought that was where everything but servers would be going. You can tune your OS and applications around the slower GDDR5 and it seemed a no brainer: instead of 8GB of system memory topping out and then 4GB of VRAM doing jack shit you could have 12GB that could be dynamically assigned to whatever you wanted!

Alas, that dream was never meant to be.

Edit: I posted about this a while a back and apparently Arch Linux has a hacky way to use your VRAM as system RAM. Good stuff.
Come on... that seems a bit dramatic. It just gets you from point A to B? It literally unlocks a ton of new point Bs that you could potentially never access or reasonable visit often.

Let's jump to Washington D.C. If you live in Northern Virginia or Maryland, you could take the Metro into town for a night out, but would almost certainly have a huge issue getting a cab driver to take you home.

Let's jump back to SF. North Beach to the Mission district. Separate sides of the town but without a cab, thats 2-3 bus transfers and forget even getting home late at night when it all stops running.

The accessibility aspect of Uber is massive. I don't think it's fair to discount that simply because the ride itself wasn't memorable...by that aspect, are airplane companies fake businesses? Does anyone really brag about the wonderful economy experience they have on Delta vs. United vs. American Airlines? Not really, but they certainly talk about the accessibility those services offer.
