zmk_··on 3M Knew About the Dangers of PFOA and PFOS Decades Ago, Internal Documents Show
What they mean when saying PFOA-free is that it wasn't used in the manufacturing of the product. For instance if you look at pans sold at Ikea they will explicitly say in the materials section: "No PFOA (perfluorooctanoic acid) has been used to make non-stick coating on this product."
zmk_··on Credit-Card Backlash Mounts as Kroger Weighs Expanding Visa Ban
In Europe at least, this would be regulation. There are max amounts on fees.
zmk_··on Farewell, Google Maps
It's not free as in you are not allowed to use OSM tiling servers for commercial purposes. "OpenStreetMap’s own servers are run entirely on donated resources. They have strictly limited capacity. [...] OpenStreetMap data is free for everyone to use. Our tile servers are not." [1]. They've even banned some sites for abusing their servers, e.g., FastPokeMap in 2016 [2]. But there is a very clear way of switching to OSM and serving your own map tiles with any styling you want [3]. I personally think that startups like these should go for these options since their user base is concentrated in one region.

zmk_··on European Commission fines Google €4.34B in Android antitrust case
This was not the case when these complaints were originally filled.
zmk_··on European Commission fines Google €4.34B in Android antitrust case
I find this fine bizarre. Sure, Android is dominating the European markets, but I find it to be a good thing. I am surprised that the EU commission never investigated Apple. I don't know when they stopped doing it, but Apple used to remove apps from their store that were duplicating Apple provided services.

I also think that manufacturers have themselves to thank. AOSP used to be quite complete in the old days, but every time Google updates it, it takes ages for the device makers to update their devices (if they do it at all); that's why so much of what makes Android great right now relies on Play Services. It was a move that was welcomed by the consumers/tech journalists.

zmk_··on Montreal Moving Day: what happens when a whole city moves house at once
In the Netherlands you are often expected to remove/install floor when you move. Also, interestingly, no warm water in toilets in there either. The weirdest discrepancy between US/Can and Europe is the amount of water in and the size of toilets.
zmk_··on China Begins to Question Whether It’s Ready for a Trade War
Less trade due to tariffs lowers the incentive for China to a) roll over the bonds and b) buy new ones. This will hit the US federal budget and in turn be noticable for everyone.
zmk_··on OpenAI Five
This is more than many academic positions pay (or cost the uni) in a year; esp. in Europe. This an absurd amount of money/resources and more of a sign that this part of academia is not about outsmarting but outspending the "competition".
zmk_··on Markets are efficient if and only if P = NP (2010)
Private information here refers to whatever insights you bring with your research. The point is that if you gain some private information (by being a quant, analyst, etc.) you would immediately trade on it and the price would then start reflecting your views.

Also EMH, and that's the point Fama uses a lot to battle critics, does not put a time frame on when the price adjustment happens.

zmk_··on Markets are efficient if and only if P = NP (2010)
EMH that this paper refers to is about financial markets. In other areas of econ, no one is claiming that markets are efficient, in fact most of econ talks about "first best", "second best", "losses in efficiency", etc.
zmk_··on Predicting Stock Performance with Natural Language Deep Learning
But that's because it is being applied by people who come from classifying cat images and have little domain knowledge.
zmk_··on Predicting Stock Performance with Natural Language Deep Learning
This is not really finance research so do not confuse the two. It is CS/ML with a financial application; two different things. Return predictability low in real data, even if you control for time- and firm-fixed effects.
zmk_··on Google, please fix Android's slow, bloated share UI
Not only have I shared to the wrong app on multiple occasions, the direct sharing is useless. I mostly use one app for IMs, but the direct share is always populated by another app.

But this is also not only Google's issue. If you direct share to a contact in Messenger, instead of just sharing whatever you wanted to, Messenger opens the share interface where you can select other people to share to. This is even though you wanted to share to just one.

zmk_··on Tesla Plunges After a Conference Call
Actually as a CEO he has a fiduciary duty to maximise shareholder value.
zmk_··on Medium tries to prevent people reading deleted articles on the Wayback Machine?
Except they do in Europe under the 'right to be forgotten'.
zmk_··on The Mathematics of 2048: Optimal Play with Markov Decision Processes
If I remember correctly Threes is free now as well.
zmk_··on More evidence essential oils 'make male breasts develop'
Sample size of 3?!
zmk_··on Manafort Left an Incriminating Paper Trail Converting PDFs to Word
Open in Chrome and print the PDF as PDF; also removes any editing restrictions while maintaining ability to select text.
zmk_··on Introducing Airbnb Plus
It is quite easy to exploit a gap. Some bad publicity about how Airbnb hosts were treatign LGBT guests and you have relatively successful Misterbnb...
zmk_··on Australia’s new real-time banking payments platform
I used the app four times since I moved to Sweden 2 years ago. I haven't touched cash, actually I am not sure how the current notes/coins (they changed them) look like. If you shop in stores/restaurants then you use cards mostly. Swish in my experience is for splitting bills (less common), at after work parties when someone buys beers and you pay them back, for very small vendors who do not want to bother with banks for getting CC terminals.
zmk_··on Australia’s new real-time banking payments platform
This is not only meant for commerce like iDEAL is. If anything it is supposed to work like the 'send to phone number' services offered by ING or ABN, for instance.

This is more like Swish in Sweden.

zmk_··on Julia v0.7.0 Release Notes
Removing eye() in favour of a new construct is weird after all this time. It seems to me like v0.7 will break a lot of my current code.
zmk_··on Apple Reports First Quarter Results
"top selling iPhone" is a relative statement, the whole pie can be shrinking and Apple could've hoped for more sales, but compared to other (8 and older) iPhones it is still doing good.

The forecasts in the media were about the absolute levels not relative.

zmk_··on Researchers find that one person likely drove Bitcoin from $150 to $1,000
This is how research in economics works. It can take even 5 years to get a paper published, although these guys seem to have written the paper quite recently. Turnaround was quick for them...

Pre-publication version of the article is available at SSRN: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2977479

zmk_··on Is Your English Accent British or American?
There should be a third mapping there---"neither". I got 99% British with my normal (more or less foreign-accent-free) speach and a whooping 88% British with the heaviest Polish accent I could produce.
zmk_··on If We Can Put a Man on the Moon, Why Can’t We Put a Man on the Moon?
Welcome to the Netherlands then. Most people ride trains between the cities. It does help, however, that most of the population lives in cities that are 30-40 minutes away on a train.
zmk_··on Goldman Sachs Is Setting Up a Cryptocurrency Trading Desk
It is not illegal as the market is not regulated right now. You can actually see manipulation in BTC right now.
zmk_··on How traders 'pump and dump' cryptocurrencies
LTC seems like a bubble.
zmk_··on Making It Easier to Break Science Journal Paywalls
In the Netherlands, at least, it will not be allowed for researchers to publish articles in journals that erect paywalls.
zmk_··on Paradise Papers: Dear Tim Cook
It's the customers who pay the VAT, not Apple. That's why electronics bought in US where the sales taxes are generally much lower than VAT rates seem cheaper from the European perspective. A higher VAT also hits more the less privileged and effectively crowds them out of the market. For goods like these you can think of the VAT is 'the price to be able to buy' and corporate tax as 'the price to be able to sell'.
