> I find it incredibly disrespectful and lacking in basic scientific integrity to go into a paper with the assumption that it is a false belief

In this context, the belief is that a spell and magical powder/paste, combined with ritual, can protect from gunfire.

Science isn't free. Also, how on earth does one go about such an experiment humanely and in a financially prudent manner? I'd love to see the reviews on the grant proposal and IRB request to shoot 10 goats in order to test the effectiveness of gri gri...

> "duh...because they are superstitious barbarians"

The authors specifically discuss monotheistic religions and miracles in the introduction.

It's possible the authors believe all religious people are "superstitious barbarians", but that seems like an awfully uncharitable assumption to make about the authors. Even if all the authors are atheists, there's still a huge gap between "person who believes in unfalsifiable religious claims" and "superstitious barbarians".

> Whether the belief is false or not seems to be totally irrelevant in trying to show that the authors' conclusions are valid. Clearly, the members of the village believed that it was true. Because of their belief in the effectiveness of the "treatment" the results were x, y, and z.

The authors come to exactly the same conclusion -- at base, gri gri is effective; its efficacy is explained by its effect on communal behavior rather than magical powers.

> Why should I automatically assume it is invalid? That strikes me as the opposite of scientific enquiry.

Tea pots in space and all that.

> The cultural hubris contained in this paper overshadows the conclusion.

You and the author seem to have come to approximately the same conclusion...
Interesting. So you're saying that it really 'spins the fans' when you run slack as a pure web app as well? It seems quite lightweight to me, on latest chrome in Ubuntu on a late 2016 macbook pro.
Numerai combines two things - a prediction competition, and yet another complicated and obfuscated crypto coin scheme.

The prediction competition is like the Netflix Prize [1]. They give you a data set and a prediction goal, you submit an algorithm, and there's a winner. OK, although if you can do well at that, you're wasting your time giving your results to Numerai. You're competing for a total payout of $15K/month.

Then, for no particularly good reason, this is combined with some smart contract / crypto coin scheme. Other than for PR purposes, it's not clear what the gain is. Everybody is dealing with Numerai; it's not a many-to-many system. It's more like airline reward points.

The hedge fund itself doesn't use Etherium; it's completely traditional.[2]

Is there evidence that Uber loses money on every transaction?

According to financials from 2015, they have higher revenues than cost of sales:

www.nakedcapitalism.com/2016/11/can-uber-ever-deliver-part-one-understanding-ubers-bleak-operating-economics.html

This suggests to me that marginal rides are profitable, even if they aren't profitable enough to cover fixed costs of software development or investments into new geographic markets.
"We realise that our revenue will most likely be a very long tail with a small number of customers bringing in most of the cash."

Either they or I don't understand what long tail means.
The same can be said about any database though. No one is like another.

SQL as a standard is roughly followed, and PostgreSQL is very compliant. That's more than can be said about any non-relational database - each has it's own query language.

I use JSON fields and arrays quite a bit, but that doesn't mean I need a document store. It means I have small portions of data that is non-relational, or is better suited to use arrays/json than strict tables, but I still want everything else consistent, enforced, and also have all the other bells and whistles Postgres gives you (FTS, partial indexes, rich types everywhere, ACID, the list goes on and on).

Being tied to Postgres is often better than being tied to a document store. At least you can dip your toes into non-rel as little or much as you like (where it makes sense), rather than diving in at the deep end and realizing you can't swim.
Just an FYI Wings3D http://www.wings3d.com/ is built with Erlang. It is a Symbolics style 3d Modelling application using the Winged Edge data structure.
"Learn your fundementals, and if a relational database isn't part of your foundational knowledge, get out."

I'll answer in the exact same tone as you to make a point.

Who gives a flying phuck for technical debt, when masturbatory, canonical code monkeys like you can be hired to fix the debt, slaving away for bosses who've built profitable businesses without a 101 in relational databases.

Cheers and may some humility grace you!

AirBnB does a lot of these — and they aren't necessarily dick moves when you're looking at something with limited availability.

According to recent reporting in Bloomberg, there was a temporary dip in market share due to the #deleteuber campaign, which has since recovered. Both companies have grown considerably over that time period. Lyft's ridesharing growth in the U.S. has been much higher than Uber's.

The Waymo lawsuit is still very much up in the air. Kalanick's involvement is already public: he collaborated with Levandowski to acquire a team of self-driving-car engineers and their work over 8 months. The key demands of the Waymo legal team were rejected in their injunction. Judge Alsop did not see a clear nexus between the Waymo designs and the Uber lidar, referring the matter to trial.
Maybe you could clear up something I've been wondering as someone new to cryptocurrencies. In the ICO, Bancor exchanges their own, newly created coins for Ethereum and the 'investors' are hoping that the new Bancor coins value will go up? So the Bancor team raised ~150 million dollars (in Ethereum) with no strings attached -- ie, no investors, debt, etc? Do I have this right?
Nope.

1) Walmart doesn't pass savings to consumers, it passes them to shareholders, as they have a fiduciary obligation to do. The "lower prices" thing is just marketing; WM's prices aren't particularly low once they've driven away their competition.

2) If drug companies want to charge a R&D premium for bleeding-edge innovative products, that's fine. What's not fine is price gouging consumers for drugs they depend on to live, that are not innovative in 2017, and that are cheaply available in other countries, like the EpiPen.
I think if you're swimming a sea of options you look for any port and Aphyr's blog gives you all sorts of ammo to eliminate choices even if they're only failing on microscopic edge cases that will never affect your small-scale project.
Congrats on the new team members!
I'm actually separating the issues rather than conflating them.

Capitalism by itself looks at profit. In the United States capitalism is held in check by a legal+political+free speech system. A company (Uber) is not held in check by more capitalism; it is not held in check by competition. As an aside, this breaks down with regulatory capture.

When VW cheated on its emissions testing it was not checked by a more efficient and competitive Tesla. It was held to account by a legal system external of capitalism.
Outcomes! Right, that's what they were called. Thanks for naming it.

Interesting, since the discussion talks about bikes laying around for 9+ months, and gathering and tagging "abandoned" bikes every 6 months.

When I was in Tokyo I saw hundreds of bikes unlocked. There was a poster with a security photo saying "bike thief." My wife mentioned it was likely that person had just grabbed the wrong bike.

I'm not saying bike theft doesn't happen in Japan, it just seems to be significantly more rare in Japan compared to most other places.

I remember hearing San Francisco was trying to cut down on the secondhand market as a way to reduce bike theft. I see Japan has a registration system for bikes. I wonder how much that contributes?

Another dutch person here. I can think of plenty of use cases. I'd like to keep track of where my money goes, and have played with programs like GnuCash and Ledger before. The big problem is getting data into them. I have a decent system where I download the CSVs, feed them to a script, and everything gets imported. However this requires me to think about downloading that CSV every month. And my administration lags behind by a month. It's also inconvenient if my system can't automatically identify the receiver, since then I'll have to help it out. Hard to do that when I have to recall where I spent $15 a month ago.

If there was an API I could use to get these details, it would be so much more convenient. Could even build a product around it.

DASH (Debian Alchemist SHell). I believe it's the default shell for Debian and Ubuntu (I'm a Fedora/CentOS user myself). I remember hitting some edge cases where some bespoke shell scripts don't work correctly on Ubuntu because DASH is a "slim" Bash alternative, so it doesn't have all the "bashisms".

Going from ~3% unemployment to ~10% overnight has caused a very noticeable change in the city. Yes, there are countries where this is the norm, just like it will probably be the norm here for the foreseeable future.

The point isn't that where I live is awful (it's really not), but that education and hard work doesn't guarantee success when there are macroeconomic forces working against you.

> We're one of the safest countries in Europe. I don't know why Americans love to lump crime together with poverty, but that's not how it works in Europe from what I can tell. Or at least in my part of Europe.

Do you have a mailing list where I can say my bank is with "Halifax let me know when you support them securely?"

Oh I considered it.
1) they always paid out USD values, but transfered equivalent Bitcoin.

2) they had problems with overfitting leaderboards based on validation sets, now they pay out based on live results resolved over 4 weeks. That was solved several months ago before the crypto currency went live or really had anything to do with it.

3) Payouts are now in both USD and NMR for the competition (based on live data).

So, they did have some problems at first, but that was solved by paying out on live results rather than a leaderboard based on validation data. That solution didn't have to do with the cryptocoin.

The purpose of the cryptocoin is that data scientists can earn more USD (in addition to the well functioning direct competition) by staking NMR. The NMR and conversion rate they require tells the fund how confident they are in their model. This additional confidence information, outlined in the paper you link, gives the fund a better idea of how to weight individual competition submissions for their meta-model that determines asset allocation.
I suspect this is the sort of thing where someone at Google is still using theirs, has access to the code via the monorepo, decided to do some updates (maybe over a while) to fix issues they were having, and then decided to get the bureaucracy taken care of to push it out to everyone.

I don't think there's much (any?) chance of this being a sudden renewed interest in Google supporting the device.
Current roaming regulations in the EU are designed with the biggest, transnational players in mind. By subsidizing operations in a less lucrative market using proceeds from other countries, they can bleed smaller national telecoms. They will then proceed to buy them for pennies on the dollar. This will result in less competition down the road, and higher prices for the end user.
I work in the IT division of a Fortune 100 pharma. About four years ago I was astonished as a senior business director proudly bragged to us about the company's successful accounts payable strategy of paying all vendor bills as late as possible. This allowed the company to earn a higher yield on overnight investments, despite the continuing outcry from business partners.

I imagine most giant corporations now behave this way, with only the little guys playing by the rules, and paying the price.
It tends to be a negative correlation.

In the Northeast US, you'll generally see the best performing districts have a lower amount spent per child than the underperforming districts.

The underperforming districts will have higher property taxes (as a result of the higher education cost). This generally leads to parents seeking to move to a different school district for financial and educational reasons.

In education, at least, more money does not equate to better students, but instead, more mismanagement.
> Some of reasons I've heard:

Here's some more:

- I don't know what the capital requirement is.

- I don't know what agreements we need.

- I don't know what machines/networks we need.

I'm also intrigued by the Numerai story. Haven't seen any numbers, though.
It takes a constant number of engineers to push a single feature, no matter the number of users.

It does not, however, take a constant number of engineers to maintain the infrastructure that lets a single engineer push a feature to millions of users. (P/I)AAS can help, but you still need people to monitor performance, find regressions and bugs, and track them down.
Thanks for sharing that historical tidbit! My understanding is compressor manufacturers don't like to work on co-generation on a small scale. However, early attempts like you describe tended to use some kind of water jacket because heat pump technology back then was finicky and much more expensive than today. Using air to conduct heat is hugely inefficient, but we're dumping the waste heat into the air anyways and then later spending more kWh to cool down the air, so the current batch of heat pump-based water heaters are a possible starting point.

In idle moments I've wondered if I could retrofit the multiple small compressors with a single large unit with multiplexed hoses and electronically-controlled relays that was designed to operate submerged in something like polyalkalene glycol (PAG fluid), insulate the heck out of that to minimize thermal conductivity to the surrounding air, then extract out the heat of the PAG fluid into the water heater. Would be a maintenance nightmare to be sure, but it would be a cool hack to play with exploring and measuring those boundaries of efficiency.

Would be prudent and indeed consumer friendly if you where to go thru those TOS the banks have in conjunction with your own and provide a simple at a glance list of liability/impact. Reassure people that way and shows, you care and thought this thru beyond saying we recommend reading this and that as people are wary and equally might not understand it.

I would like to make a claim that ETN doesn't reduce complexity of programs, it merely splits it in two: the TN that declares the data structure and the interpreter on the other side. To fully understand a piece of code one has now to study both sides.

In a bigger program, and because this approach seems to encourage the proliferation of DLS, one has to do the same process repeatedly. It seems to be a lot of context a developer has to maintain in their head.
Some banks (Cap One 360 formerly ING Direct) allow you to generate a site-specific passphrase, so you would limit your exposure if Mint got hacked.

Sanders vs. Trump would've been a much more interesting election

I agree, and it continues to perplex me that the Sanders campaign didn't put int he effort to develop a detailed policy agenda in parallel with the noble principles it was articulating.

You can blame people, if you like, for going with the sole candidate who at least pretended to give a shit about their problems

Oh please. I did not find Hillary Clinton a charismatic or especially empathic candidate, and her cautious incrementalism was a timid and unimaginative alternative to Trump's bold and dramatic (albeit shallow and stupid) vision. Clinton would have done far better to announce that her plan was to end poverty in America and establish a colony on Mars by 2030. People would have challenged that as ridiculous and impossible, of course, but it's no more absurd than the idea that we'd build a 20000 mile long wall along one border and get Mexico to pay for it.

What I'm disagreeing with is your suggestion that Clinton did not give a shit. She had a really detailed and well-rounded policy agenda whose primary fault was that it was too pragmatic and boring and cautious. It was not the right agenda for the times, but it's unjust to equate lack of vision with callous indifference. To say that is to accuse Mom of wanting you to starve because she insists you eat your vegetables. Sorry for the crude metaphor but the last election was in many ways a choice between Mom and Dad, and I think it's foolish to ignore the psychological dynamics that were in play.

I think we should also recall that she did manage to get 3 million more votes, but the GOP proved themselves to be superior electoral tacticians, possibly with help from some friends.
If my memory and understanding are correct, the way that Mathematics is graded at Cambridge is interesting here.

I'd say it's crucially important, especially if you want to advance over time. Technical knowledge alone can only get you so far. Especially in highly specialized domains like health-care (and I saw this as somebody whose dayjob is in healthcare analytics). Of course you have to strike a balance between leveling up on hard-core technical skills AND domain knowledge. Unfortunately I don't know any strictly deterministic and universally optimal way to decide where that balance is. :-(

How do you go about developing domain expertise?

Other than working "in the business" so to speak, of that domain, I can only thinking of the regular stuff: read books, read articles, watch videos, interview people, etc.
