> The problem with chargebacks is that they're mandatory, even in cases where the seller is more trustworthy than the buyer. Then you end up with all the losses associated with buyer fraud even if the overwhelming majority of legitimate buyers would have enough faith in the seller to waive the ability to conduct a chargeback in exchange for a discount in the amount of the fee that has to be charged to cover them.

This is actually accounted for in the merchant interchange rate. It varies by MCC (merchant category code) [and potentially merchant to merchant] and the frequency of chargebacks is built into how much the merchant pays for processing. Further, that bubbles up to the customer in terms of the pricing. Merchants may offer cash or other payment method discounts, so in a sense, what you're asking for already exists. Merchants do not opt into it because it's not in their interests.

That said, that's not how the math works out. If a buyer has a number of chargebacks, the buyer may be investigated and has their account suspended or is charged with fraud. This works both ways. Again, merchants and payment networks are aligned in this case, both make money on greater transaction volume, this feature increases transaction volume, that's why it's there, otherwise it wouldn't be there.

Also, paying per-transaction isn't really insurance as it leads to massive adverse selection risk. The most helpful chargeback for me personally was a two thousand dollar chargeback against Expedia where they refused to refund a refundable ticket. I filed a chargeback and I got the money back within a few days.

It's a good thing, unless you've got data to back your case.
Maintaining a pipeline that works takes effort that can be spent somewhere else. As long as it can be reproduced with a little effort from me, I really don't mind. I would rather they spend time to try a lot of different things, build intuitions, and search better backbone structures than maintaining a CI system so that every time their code updates can train imageNet to < 20% top-1 error rate.

That should be left to TensorFlow model zoo or GluonCV model zoo. I simply look at these research "open-source" as reproducible research.
> our gov’t has yet to find a solution.

Then why don't they do something about that?

Because it might increase their taxes. And god forbid a red-blooded American pays 1% more tax on the income from their hard-earned jetski dealership...

They care, but they certainly don't care enough to do anything about it, and the government is a symptom of that. Isn't the US supposed to be a 'democracy'? Why can't the government be fixed?
Would any of this be a problem if social sites would restore chronological news feeds?

99% of these “problems” stem from newsfeeds that are algorithmic rather than simply chronological.
Yeah but I wonder what fraction of CS papers test the algorithm that they thought they were testing...
The reality is that it won't do much to protect users privacy or prevent tracking, although it will make it easier for users to avoid spam filling up their inboxes.
Yes, this was a huge disappointment when I read Chemistry & Physics years ago. The naive view of papers was that they were to move human knowledge forward, but it became clear they were an elaborate knowledge withholding device!

Fortunately the trend seems to be towards better levels of openness, but it varies by subject. Stories like the BASF team being unable to reproduce vast numbers of established published techniques are way too common.
I'd be willing to settle for a 4K HDR display on my laptop first
Tim Cook and the Board of Directors, no? Of course there will be other who initiated and are spearheading the effort to include in the cheers.
>> A shakedown for a bribe is a negotiation.

It's only a negotiation if the official has any chance of being prosecuted for that bribe.

>> But if you have a piece of paper that says “I am so against bribery that I carry around pieces of paper that say so” it makes the cop lose hope of getting the bribe.

Or well, the cop simply arrests you and puts you in jail for a week during which you can't go to work to afford food for your children.

>> If a person is told “pay this $100 fee right now or I’ll have to take you in” and says “no”, the cop may lower the price, raise the price, threaten more, or follow through on the threat to try to get the person to pay up.

There was a thing in Russia about a decade ago for people driving cars with European plates: a cop stops you and says you're drunk. You argue with him, so he takes you to a doctor. Doctor says you're drunk.

So the bribes went as $10 for the first time and then $100 at the doctor's. If you were smart you knew you could loose the license in Russia and then simply report it stolen in Europe because nobody shared databases.

> The article explains how Google through Chrome's dominance is doing and did exactly this via webstandards for DRM despite most of chrome being completely open-source via chromium.

Yes, but it also fails to make much of an antitrust case about this. I mean, is Widevine licensing anticompetitive? Discriminatory? Surely it would be hard to make a competitor for it. But at the same time Apple and HBO seem to be streaming a ton of content without it.

The harm to open source media playback is real, but that's not an argument about market health. Frankly I'm pretty doubtful much antitrust hay can be made about this. We watch Microsoft choke Netscape to death in the 90's, and at the end of the day nothing happened. Maybe Google will be forced to spin off the Widevine IP to a separate company, I guess. No one is going to kill Chrome for you.
When the light shuts down in the west, it shines brighter in the rest.
In media studio environments, it' makes some sense...but it's mostly an iMac on a cart these days.
There are two prominent examples of antitrust/monopoly problems in the U.S. real estate market: MLS and dual agency. The MLS seems to be complicit in forcing home sellers into paying higher buyer agent commissions: https://therealdeal.com/national/2019/05/22/doj-demands-core...

With consolidation of real estate brokerage firms, many home buyers may have overpaid due to a single firm representing both home seller and buyer, known as dual agency: https://therealdeal.com/2019/05/01/houlihan-lawrence-fails-t...

There is a third issue of large private equity firms buying large volumes of houses that may, in the future, warrant an antitrust investigation.

I paid under 3k for my PowerMac G5, ~3300 for the original Mac Pro after that, then 3k for my current 4 core 2013 Mac Pro. This is definitely a course change on the entry level pricing.
Academia isn't flawless, it's no paradise. It's just humans and their factions, with all the good and bad that brings.

> The authors are ... constrained by space due to paper limitations

This is very real. Different journals have different criteria: word count; formatting; the number of tables you're permitted to include; etc. It's archaic and daft but that's the truth of it. And that's before we even get started on the really bonkers stuff like author order, impact factor, reviewer workload vs lack of pay, publish or perish, and so on.
I can't log out of Facebook on Firefox, FB seems to have bugged the dropdown containing the log-out button so it loads forever instead of appearing :(
Speaking as someone who has read about 40 years of papers in compiler optimization, it's very interesting.

In the early days, there were fairly exact algorithms that worked as described, and were implemented as described, but were pseudocoded in papers. Where the pseudocode differed from implementation, differences were described in great detail (IE they may say an array can be shared but isn't to make the pseudocode easier to describe).

Then, over time, things start to get further away from that. You start to see papers published with algorithms that either don't work as described, or are so inefficient as to be unusable. Like literally cannot work. Where you can get source code, later looking at the source code shows that's not what they did at all.

One infamous example of this is SSAPRE - to this day, people have a lot of trouble understanding the paper (and it has significant errors that make the algorithm incorrect as written). The concept sure, but the exact algorithm - less so.
Reading the source code to it in Open64 - it is just wildly different than the paper (and often requires a lot of thought for people to convince themselves it is correct).

It's not just better engineering/datastructures vs research algorithms.

The one shining counterexample is the Rice folks who wrote their massively scalar compiler in nuweb (one of many literate programming environments), so the descriptions/papers and code were in the same place - these are very very readable and useful papers in my experience.

Nowadays it's coming back to the earlier daysdue to github/et al. People seem to try to make the code more like the paper algorithm since they now release the code.

Word2vec appears to be a counterexample (maybe because they released the code they didn't feel a need to get the paper as right)
One explained to me here that the problem is they're mainly rewarded by funding agencies for how many papers they publish. That's why quality went down in general. Then, since funding agencies aren't rewarding code, they're either not encouraged to get it right or actively discouraged from doing it to focus on next paper.

This sad situation is both bad for open source and science. Bad for science since inaccurate results that probably aren't even reproducible aren't the knowledge advancements we need. Funding agencies like NSF need to change their policies to address the root cause here. Universities will follow where the incentives lead them.
I work in industry I've seen some of the same things. The IT policies at my work do tend to be overly restrictive but I think it is somewhat understandable there is maybe two thousand people that work at the plant I'm at. 10 to 15 years ago someone made the decision to outsource IT support (before this every department had IT specialists) there is just no way external support can scale to the level its even feasible to think about giving everyone on site admin access or similar. So we've ended up in enterprise like situation with creeping bureaucracy where everything is super locked down and if you need some software installed submit a ticket get a manger to sign off on it (and be prepared to argue with them about why it's necessary to get this software installed) and maybe 1 or 2 weeks later ticket will get actioned (if you are lucky and it doesn't end up sitting for a month in purgatory somewhere).

Excel is part of standard environment so it is present on every fresh installation here so there is a tendency to reach for it. The "I can open up excel and start working on my problem now, or I can submit a ticket and wait two weeks" attitude is a real thing. The other issue is "I know I have excel installed and I know Bob has excel installed - who knows what else Bob has installed already so if I want to collaborate with Bob I better just use excel."

Personally (I work as an Engineer - the non software kind) I think excel is fine for rapidly prototyping something and as a first pass solution for when you need to quickly answer something but once you've reached the stage a spreadsheet is needed to run process it should be rewritten in something more robust - preferably before it reaches that stage.
I have seen several where there is a separate light for right turn (for cars) and straight/right (for bikes). It seems to address this problem, at least.

Still not as good as the dutch system, but easier to retrofit I suppose.

Given the high cost, high cost options exist on other platforms that are also fantastic.

So if everyone can spend 3,000 dollars and get best in class computing, what are you paying for with Apple?

They have lots of marketing that psychologically makes you feel good?
> I don't think that's really an anti-trust problem

What kind of problem is it then? High prices being maintained by a purposeful conspiracy of existing owners to constrain supply sure sounds a lot like an antitrust problem.

> It's a matter of giving the majority of residents/voters what they want, even if it's bad for them in the long run.

But it's not necessarily bad for them. They make more money by monopolizing the local real estate market in the same way as any other cartel monopolizes anything.

Even if their choices are bad for the city itself, they may be planning to sell and move to another area before the long-term negative consequences to the city are felt.
On a similar note, a long time ago I read the Doc2Vec paper, then looked at popular Doc2Vec implementations. They didn’t seem to do the same thing. The paper said you basically make vectors for words, then append on an additional space that represents the additional information of documents as opposed to single words.

All popular implementations I found seemed to put the document vectors into the same space as the word vectors. They also didn’t seem to do any better than a tf-idf weighted average of word vectors... curious if anyone has ever bumped against this.
This is so sad, but unfortunately so true :(

And I really have no idea how to solve it without an effective replication/peer-review process, which is currently not popular for scientists trying to make a name for themselves.
I'm not totally sure how the rating system works but I think that behavior could get you locked out pretty quickly? I would think giving a low rating for the ride is still effective and doesn't jeopardize your ability to still use the service.

You could also just ask the driver to turn the screen off without threatening to cancel the trip as a first step.
Completely agree. The situation today is far better than a decade ago, with code releases for machine learning and computer vision papers being much more common than before.

I try to make my students release polished and easy to use code, but it can sometimes fall through the cracks due to deadlines, etc. Many projects are the output of a single PhD student.

Poor Jackson got the honor of being featured on the US zero note. I kind of want to put Trump's face there.
Sorry, but it seems you don't understand how the knot actually works, because if you are arguing that the choking part of the knot might get loose, then I can counter argue that regardless of how big your stopper is, still has "the potential" to go through the chocking part. That's not the case. Here is some data: https://www.yachtingmonthly.com/sailing-skills/strongest-sai.... Note that the knot did not fail, the lines did. Also, note the loads they are talking about, >1 tonne.

As a sort of meta, you are not making your point any easier to accept the way you presented it, you start off by stating "it has a tendency to come undone [...]", but then switch to "it has the potential to work it's way loose given enough wiggling".
I think the Macbook and Macbook Air is much worse, but I suppose it's unclear if both are currently active lines.
I’m getting good enough to keep them on their toes... I think!
I think it was better if there was a general speed limit at around 120km/h.
Driving in Switzerland or Austria is in general more relaxing and needs much less fuel.
But I have to admit there are things I like about being able to drive 200+km/h. First is acceleration. Being able to put the foot down and just accelerate (even in the end it‘s just accelerating to ~120) feels great. The second factor ist actually driving 200-220km/h. It‘s not really fun but it is a strange feeling. A mixture of of tension and relaxation and hyperfocus. You have Focus on your driving because you know an error (it does not have to be your error) can kill you but on the other hand you fell calm and feel you have control and through your focus everything slows down. It calms me. I would describe it as almost meditation, having never meditated.
I know thinking about it I should not do it, and I should not praise it and I probably should have used a throw away, but it has some appeal and even just writing about it triggers some of those feelings.
If the healthcare industry used medical id numbers instead of SSN's that would help. Better banks should be forced to stop using SSN's completely. And forced to use 2factor. Preferably both.
I am joining a new company as a Senior Software Engineer soon—thats one of the main drivers of this. I’m going to likely be in the position of giving others guidance on prioritization. Now, sometimes it will be obvious, but I’d like to be prepared for when it is not.

I would say that my last employer did give me time for thinking. However, I’d like to spend more of my time on harder questions and to get to be more efficient at resolving this particular sort of ambiguity. I’ve long felt like I wasn’t as confident in my prioritization as I ought be. Thats why I say I want to be able to explain my prioritization.
At least in that case there are three letters of difference, instead of one :P
Well, I bought the nice physical calculators because I needed the functionality that they provided over the cheapo calculators.

The difference in hardware (processing and screen) between e.g. a solar-polared four-function calculator and a TI-89 are representative of a difference in potential functionality and manifest with a difference in price (driven by real-world production costs).

However, one app doesn't have any less resources than another and/or doesn't have any hardware differences that would e.g. add cost if you want to visualize a graph versus compute a number -- outside of the software costs. I guess I just assume all apps are a race to the bottom here, then, because I find it mind-boggling that there aren't free apps with functionality that mimics any and all paid apps (especially in a calculator app specifically, where the dev-work is generally just _making it_ rather than inventing something new).

That all is to say: thanks -- I guess it's just a difference in features and quality comparing paid apps to free apps here. I don't really understand how that is the case (why don't people continually make cheaper/free calculators of equal quality?), but at least I understand the how. :)

Slate actually declared "Google+ Is Dead" in November 2011(!)
There are plenty of countries that would have opened BER in the state it was in 5 years ago, either sweeping problems under the rug or fixing them during operation. The airport is as much a testament to bad construction as it is to safety inspections and rules trumping economic interest.

A lot of children do not even know what engineers are or how to become one.

I was blessed to have an EE stop by my 6th grade math class and give a presentation about engineers and what they do and about how it was a good career path for people who were interested in making things or technology.

I decided right then to be an engineer, making course selections when I had a chance to make it possible. Without that encounter, it would have been much harder as I would likely (a) not known about engineering, and (b) not known how important it was to take the right courses.
I build hydraulic models of water systems for UK utilities (but live in Canada), one of the things we look at in the model besides the performance of the network is the age of water.

In the UK, pipes are sized based on the needs of the domestic demand, while capacity for fire flow is not considered. While in North America the opposite is done, where the network, including capacity in tanks and pressure within the network, must take into account fire flow requirements. (The attached EPA document goes into this in more detail)

While a UK residential street may be supplied by a 100mm main, the same street in the US may need a 200mm main. That's a four-time increase in volume that needs to be turned over in the pipe for just a little street!

I have seen design documents for North American towns requiring flow rates of 50-90l/s to protect a single house. When I tell my colleagues in the UK about this they laugh and ask if I'm joking and if the fire bridge is aiming to simply flatten the house to stop the fire.

Pressures in North American networks are also higher than in the UK, once again to meet fire flow requirements, which leads to higher background leakage and bursts within the network.

High age of water is an issue that will affect most North American water systems regardless of if they are shrinking or growing.
It's not official currency.
Thanks! That's exactly what we wanted to know.
I think if they would have released an i9 model with a better GPU at say, $3499, then they could have sold a lot of them. I don't see any point in server chips and ECC ram being bottle necked by a single weak GPU with proprietary upgrades.
>why bother with the work of arresting them?

Sport, ego, anger, setting precedent, higher payout after arresting etc. Any number of reasons. It's all fun and games to give 0 rupee notes, until you are locked up. And then your bribe to get out has gone up manifold, unless you are willing to fight it out in a court (which you aren't).
