Articles like this should have, in the opening paragraphs, a statement like, "This is for the general case, there are many outliers." For instance, not all non-relational databases are NoSQL. What about hierarchical databases (LDAP)?

The other thing this article totally fails to address: Why NoSQL was so problematic early on. How Mongo by default would let errors fail silent in Java and other drivers.

She doesn't address the huge limitation in many NoSQL solutions: consistency. She briefly mentions ACID, but neglects the primary use case for document based NoSQL: if your data doesn't need to be current on ever read. So a blog is a great example, or any type of social network really. It really doesn't matter if you're reading a version of the comment thread from 20 seconds ago or 5 seconds ago (as long as it's not like 2 minutes ago).

The author also classifies all NoSQL as document stores, when they're not. Mongo uses a document model/concept, but others may use a model that's more like a distributed memcache or key/value store. There are things like Apache Geode which uses a distributed object store with client based schema versioning. The data model space is pretty big and they're pretty different fundamentally.

The author mentions how a lot of solutions use both, but in other posts I've looked at and other companies I've worked for, I've found that you often have to require both. In a lot of implementations, people use both a NoSQL and a relational store; one more as a fast read cache and the other for long term persistence. Then you get into all the issues with insuring consistency between the two and it's a miss.

Overall, this is a pretty basic article and not one I'd recommend. It can lead to the wrong decision for a project.
I don't see the problem. Self-LART's have a long and colorful history.
Yeah, that was a glaring error by the author of the article... However, upon re-reading, I noticed this sentence a few paragraphs above:

> "The bacteria get all of their carbon from just one source, be it methane or carbon dioxide,"

So I'm guessing the author really wanted to say "the bacteria's ability to fix carbon from methane and carbon dioxide is of particular interest".

I'm guessing that the full cycle is the same as the above-ground cycle of photosynthesis (CO2 + H2O + energy => O2 + food) and respiration (O2 + food => CO2 + H2O), except replacing photosynthesis by chemosynthesis.

The arXiv 2016 budget is online: https://confluence.cornell.edu/display/culpublic/arXiv+Susta...

They estimate spending just over a million dollars this year, funded via members (university libraries contributing a few thousand dollars each) and grants.

However, as I always point out, we must remember that the costs of a published journal are higher for reasons other than profit: journal articles are typically converted to HTML and XML via semi-automated processes with manual proofing and tweaking, production staff and some editors (for the biggest journals) are paid salaries, peer review involves chasing down deadline-abusing academics over weeks or months and building some kind of review tracking system, articles have to be reliably archived (e.g. lockss.org), and so on.

Then add that most journals are still printed and distributed by mail for some reason, and you have extra full-time staff and equipment.

I wouldn't want to throw all of that away and just keep the arXiv. Ditching print makes sense, some things can be better automated (we need better tools than LaTeX or Word to prepare papers, so they can easily be produced in PDF, HTML, or semantic XML form), and some services are unnecessary (I've had journals copy-edit my articles and make no useful changes), but I don't want to just read crappily-formatted base LaTeX from the arXiv with no frills either.

(Incidentally, PLOS is non-profit and still has to charge over $1000 per article in PLOS ONE, to pay for the professional staff and all the manual manuscript conversion gunk. Biologists love Word, so converting must be hell.)

My understanding is that there's a few uber-rich that push for reform specifically because of this (or at least they use this argument on their less agreeable brethren). Being rich is only useful if there's enough stability to allow that fortune to be used.

I personally think SQL v. NoSQL is less useful of the two dichotomies, the other one being OLTP v. OLAP. In the end, SQL is just an API. You can put SQL-like interface on NoSQL as well (like SlamData for MongoDB or Crate for Elasticsearch).

On the other hand, OLTP v. OLAP (transactional v. analytic) is directly tied to use cases and has more profound consequences as far as technical decisions go (data structures, algorithms, etc.)

It would be way too easy to adjust your net worth, and assessing said net worth would be extremely difficult. Making the tax code harder and more complicated is probably not the answer...

Net worth, as in property value - mortgages? Most 'middle class' people have most of their net worth in their principal residence, so you'd be adding quite a shocking tax bill to a lot of seniors on fixed incomes who own their own house. That's the problem with Mark-to-market taxing.

You could start added loopholes to your "block loopholes" law, like "If you reside in the property, it's tax free", but then you hit problems like parents given their kids properties as tax shelters, and the like.
They have the Bank of Musk, which is a massive advantage. Apple does have all of that cash on hand, though, so that's less of an advantage if they are truly working on a car.
It changes the nature of the site.

I fully think open peer review in various forms, is awesome and should be pursued, but the arxiv serves a more fundamental need as well: To simply make the papers available. Within the fields where arxiv is established this is not an issue, but we need to get adjacent fields, and really everyone to agree to a publicly available database of research first. There is still considerable reluctance in some quarters to upload to the arxiv as I found out after changing fields.

The arxiv should be a pure database, then we can think about various ways to build on top. That could be arxiv overlay journals or journals that try out more fancy, new peer reviewing systems that might include curated comments [0].

As long as there is considerable disagreement over what the right format for serious commenting on papers is, arxiv should not be taking sides.

I would argue the bankers who packaged sub-prime mortgages as securities, knowingly stocking bullshit investments in large enough groups where they looked ok, and fudging the numbers to do it in most cases. In my mind there's no difference between that and for example, selling a lemon car and should have a similar outcome.

> More and more people live in an urban area and more and more young people use public transportation way more often, than cars. Additionally carsharing makes owning a car in a german city kinda obsolete.

It is this. What you're missing is that in the whole wide US, the number of European-density cities where most people can choose to forgo routine use of a car can be counted on one's fingers. The common layout here is a few walkable commercial blocks "downtown", that generally serve as single-destination stops for drivers who live further out.

Self driving is what's required to make the car sharing frictionless and on-demand in less-dense areas. Currently this role is being done with human owner/operators; replacing the humans with software will reduce prices and consolidate ownership of capital equipment. (Interestingly enough, it will also decrease the stickiness of supply. Instead of needing to slowly recruit driver mindshare for a new intermediary, a straightforward investment in a fleet of cars suffices)

That being said, I think this article is a bit hokey. Apple "pivot"? mm hmm.

Careful, your karma might not take the hit from the autonomous driving crowds at HN. I keep looking at the state of the art systems for autonomous vehicles, and shake my head. I don't expect to see them in use in the US in any serious numbers before I die. The obstacles are just too complex/difficult. We always denigrate people's intelligence, but the human mind is pretty incredible at processing things spatially, even when distracted in a minivan hurtling down an Interstate.
The higher the marginal tax rate is, the more 'friction' there is moving money from a lower performing investment to a higher performing one. I.e. it produces less optimal investing, and that is less good for the economy.

The other problem with higher tax rates on investment is one winds up with less money to invest. There's a non-trivial economic cost to that as well.
Anybody know the list of emoji autocomplete? Some things like taco works but boat doesn't.
The company's Facebook account only appeared on May 1st and their Twitter sometime since then [1][2]. It also appears that their website only became public on May 4th [3]. Given the recentness of their public presence, I would not imagine that they were expecting this much publicity yet.

I think that they are legitimate because the "What's Inside" photo for the Nikola One is definitely an export from a real CAD model [4]. And Google Image search cannot find the photos they have on their social media profiles used anywhere else besides when referring to them [5]. That said, they seem distinctly in the prototype phase and have a long way to go before actually shipping something. Tesla took 6 years to ship less than 150 cars. [6]

The Truck seems very interesting, if real, they claim it is [0]

With the range of 1000 miles A - it can provide enough distance for arriving at a cargo bay; B - enough distance before the driver is required to rest (at 50mph that's about 20 hours of driving) and can recharge the truck.

Aside from the obvious environmental impact (as long as the electric source is not coal), an electric truck makes it an easier pathway for having autonomous trucking.

How do they maintain a useful number of and a high quality for links for each node, without the scalability problems of a human editor?

When I've thought about systems like this one, I always get stuck on that problem. If you automatically create every link between nodes, you end up with terrible signal-to-noise for the user; even 50 links (I'm guessing at a threshhold) seems too many to read through in order to find the one you want, and too many for the user to conceptualize. Imagine how many links there are to nodes like evolution or relativity.

The solutions I can think of:

* Categorize links, so the user can narrow their search

* Rate links by value? Relevance? How do you do this without a human editor?

* Efficient user-created filters for links

* Directional links: e.g., Many nodes may link to relativity, but relativity links to only a few

* Expert human editor, who can identify valuable links, but that wouldn't seem to scale

* Crowd-sourced links, but I would expect quality and signal-to-noise to be too low for serious research

IME, for serious research, nothing automated approaches the value of a professional reference librarian.

Surely by that logic we should give up trying to tax the rich altogether.

The rich will always try to dodge taxes, but we can make it harder, say for example by spreading it out over different forms of income and consumption.

We should also be looking at the international stage to diminish the value of tax havens, offshore companies etc. I think many countries are beginning to realise that ever lower taxation rates are a race to the bottom.
Hopper would be better IMO.

When Uber first started, in your account settings you could set a tip amount. They took that away at some point.

Sometimes I change my mind about where I'm going and take a totally different trip than planned - and when I like the driver or make them go out of their way, like say "I'm going to make several stops" and they aren't expecting that, then I sometimes tip them.

However, when they fuck up my route, like for example me telling a driver I was going to alameda and he gets off the freeway in San Francisco instead of going across the bridge as to be expected and wastes my time, I complain to support@uber and request a refund.

Uber support has actually been quite good for me. I recently was mistakenly charged three times for one ride, and they fixed it very quickly.

AirBNB on the other hand has horrid support from my experience.
What they are suggesting, offering non-western philo courses in philosophy departments, just moves the divide within the department but doesn't remove it. Philosophy courses are centered around problems and should be independent of culture. Are there philosophical problems that exist in the east but not the west?
> I really really hate American tipping culture. Even after living here a while it just seems so pointless, is completely arbitrary, and makes simple transactions more complicated.

You aren't alone. I've grown up American and constantly wonder "do I have to tip for ___" and what is "normal" for the service in question.
There's already logic programming and more generally declarative programming, which sort of have the features you describe (the programmer describes what is wanted, but not necessarily how to find or do it).

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

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

It's clear that these paradigms can be easier for solving certain kinds of problems. For example, they're very good for solving puzzles like Sudoku; instead of writing a full-fledged Sudoku solver, you can, in some of these environments, basically just describe what would constitute a solution to your problem, and then the programming environment can find one for you.
Could you extrapolate on your experiences? From what I saw (in Germany, Poland, and Italy), it is that people aren't paid to give a shit about the customer outside of the context of their service. No "how is everybody doing today?" No "have a nice day." You are there to be served and that's it.

Then again, these kinds of attitudes can change dramatically across national boundaries; the perspective I have often heard about France is that "the customer is always wrong."
List is as an AMT. Also, $10 million * 0.1% = 10,000$ which is a tiny tax bill at that wealth level. If your paying less than 10k and have 10 million then somewhere something broke down.

IMO, you would need a much higher number. A 0.5% wealth tax AMT would = a 25% tax on a 2% ROI or 8.3% on a 6% ROI.

From an economic standpoint this is actually a good idea. People with lot's of unreolised income are often stuck with unproductive assets because selling them incurs a large tax bill. With this you can sell a reasonable chunk of your assets without incurring extra tax.
Bah. People keep confusing the syntax with the data model. SQL is simply a notation to express theorems in relational set theory. It's pretty much the only pure-functional, side-effect-free programming language that's actually gone mainstream [0]. If you look carefully at the APIs of the "No SQL" databases, you'll find them introducing relational set theoretic features.

To paraphrase Paul Graham's unbearably smug comment about Lisp: once you add filter, group by, and join, you can no longer claim to have invented a new query language, just another dialect of SQL. Math has this funny habit of remaining true no matter how many mean things people say about it on their blogs.

[0] I mean basic core SQL, not the vendor-specific stuff like PL/SQL.
Wow. Every time I've used Uber the driver has been quiet outside of friendliness and greetings until I engaged them in conversation (London, so maybe not as fussed about tips/pay?)

I think I'd have to tweak my 5-star-unless-we-crash rating system if I had someone ranting against the company they're driving for
> This is really scary, scary stuff

Perhaps. It's been happening for a decade in the UK though:
https://en.wikipedia.org/wiki/Automatic_number_plate_recogni...

> Vehicle movements on UK roads are recorded by a
> network of nearly 8000 cameras capturing between 25
> and 30 million ANPR ‘read’ records daily. These
> records are stored for up to two years in the
> National ANPR Data Centre

Generally no effort is made to disguise it. Police cars have the letters ANPR stamped on them in big letters if they're carrying one.

The profiling you're worried about happening is explicitly touted as an aim of the UK government effort.

The UK approach often appears to be pro-surveillance, and then letting the courts work out what constitutes reasonable usage, a luxury afforded by having such a robust and independent legislature.
If the generated taxes flow back into the economy by building roads, bridges, etc. - that is considerably better than sitting in an offshore bank account.
But without all the toxicity.
When I use Uber, I frequently ask the drivers how often they get tips. They tell me that about one third of the time, the rider gives them some cash. (This is anecdotal of course, but I've asked roughly 30 drivers. Some drivers say they never get tips).

FWIW, I have found that Uber drivers are frequently eager to talk about their experience with Uber and their opinions. I've heard a wide range of feedback from "Uber is evil but I need this job" to "Uber changed my life".

But all drivers seem to agree tipping should be built in.
You have to enable it by configuring the maximum number of workers per query, and then the query planner tries to figure out if the query would benefit from a parallel execution. This is the first release with parallelism so I would not be surprised if the query planner gets this wrong in some cases.
I don't agree. As I said above, if I am happy with a service I get I will tip. If I am unhappy I contact support and demand a refund - it has worked well for me and I have been using uber since pretty much day one.
I'd prefer it but one you mention can be done upstream by library developer with secure defaults. Think NaCl. Client-side certificates might come with best practices or checklists that show proper use with optional data on the way. Neither issue requires understanding SSL in common deployments.

Note that I say this while agreeing with you that I prefer someone who knows what they're doing. Especially as SSL support isn't usually at the usability standard I'm describing. Yet, it's not intrinsic to the problem: just crap UX.
"you'd be adding quite a shocking tax bill to a lot of seniors on fixed incomes"

If there are unlikely seniors on fixed incomes with houses worth more than $10M, then they may pay this tax with shares in said house.

When their heirs come into possession of that house, they have to buy those shares back. 15 years of tax will be 1,5% market price.
That happens, when a content marketer write about a technical topic... Just sad.

The way the progressive tax rates work in the US, you truly have to get to a pretty high level of adjusted gross income to average 34%. In 2011 the highest tax bracket was 35%, so you couldn't even pay 34% until you earned $379,151 or more.

Given that you'd only pay 35% tax on the money earned above $379,151, so it'd take a pretty darned high income to bring your total tax rate up to 34%.
I admitted that tipping gives a good incentive to the person providing the service as I myself felt before. But I dislike tipping as I see people react differently whether you tip or not and the amount you tip. It was quite hard for me to really know what percentage to tip the person happy and to continue a good service. How do you gauge the quality of the service to tip 15-25% or even higher? That's just playing with our emotion.
I'm not sure how this keyboard could work any other way - the whole value prop is that you can search from the keyboard, and it would be pretty hard to send your search queries to google if it couldn't send the things you type to google.

the app store description is pretty clear on what it actually sends to google, and it's actually less than what most keyboards send - swype, the standard google keyboard on android, and i think most others send everything up to their respective servers so they can sync personalized predictions across devices, this keyboard only sends the queries that you explicitly ask google to search for.
