No.

EAVT is great as an intermediate format but it is absolutely useless to query for since most of the time you are trying to find a set of attributes for a given entity i.e. full table scan.

What you want is a "wide table". One entity column and all the attribute columns to the right. Often with most of the values set to null.

This is the dream use case for MongoDB since it you can ignore sparse values yet when you query it via their drivers it will appear as a wide table. You can't do this at all in PostgreSQL since you will hit a column limit.

Bombs can't just sit there forever! I'm sure some of the inventory turnover has a pretty hard limit and they gotta move it out of the warehouse somehow.

It's not like the good old days when they'd just drop old ones in the ocean.[1]

They have those in the supermarket. If you want the same thing wrapped up in a startup package, try https://www.freshly.com/
> The only thing realistically driving WeWork's valuation (outside of the "SV pixie dust") is the potential for WeWork to sell direct or become a marketplace for ancillary services (e.g. business software, legal services, etc).

The way they go about doing that looks like an ad-ish model. "Here's a bunch of vendors that were willing to pay our vigorish to be shoved in front of you." That's tough to build a premium around if you don't scale the ads, or have a compelling story for the advertisers on how much more effectively WeWork converts their co-working renters than, say, Google AdWords. An A-B test WeWork might carry out is put in an AdWords campaign side-by-side with a WeWork-based campaign for as many vendor types they can think of, and measure the results between the two on an ( ad-spend : sales_expenses - revenue ) ratio basis, and tweak their strategy model from there. If I'm one of the vendors WeWork is trying to pitch to their co-working renters, then I'd immediately be thinking, "they reach a smaller audience than my AdWords purchases (or whatever other marketing channel I'm comparing to), but supposedly more targeted, so if I put some spend there does it really perform?"

If you are a new startup, then there is a lot of bullshit in the business world that wastes a lot of your time because you simply don't know better on what to spend your limited time upon. Having a SCORES-like concierge/advisor service on tap (for a fee after an initial time of trying it out, perhaps) might be another way for WeWork to build premium value. But not scalable.

If the premium on-site staff is highly attuned into their renters' concerns, etc., that might be a way to add value by using that information as a development input. But that's very non-scalable.

Their core value proposition seems to run right into competing against Google on an efficiency basis, so I must be missing something the investors didn't.
> "Most applications today run on a database technology that was introduced in the 1970s," Ittycheria said. "In the '70s, I was using a rotary phone to have a phone conversation. So people are looking for a modern, scalable and flexible platform."

It's like a weird version of the Turing test where you have to decide whether someone's speaking seriously or in jest when they talk about NoSQL.

You'r right but it does say that if you live well below your means (more in poverty) your chances of being robbed increases. Living among poorer people than he can actually afford does increase the crime around him and probably subjects him to more crime as well (I didn't research this last correlation, just a practical guess. If you can provide research pointing otherwise please do, it will be an interesting point to know).
I think it all comes down to what definition is of solving a problem.

What Mongo did is implementing these features just well enough so they can put checkpoint in their marketing brochures.

When you actually start using it you learn that most of it is either performing slow, does not work correctly or once in a while corrupts your data.

Yes they hit these points hard, but only from marketing point of view. They are now universally hated by ops and developers because these people now have to deal with fallout.

RethinkDB actually is an example that database is something that's not good as a base for a startup[1], and the Open Source approach (like PostgrSQL) is more suitable.

MongoDB is example that you can base a startup on a database technology and succeed, if you can sleep well at night that your product can cause people to lose data.

[1] The reason RethinkDB failed was because they refused to provide half solutions like MongoDB, everyone expects startup to start making money, but building a reliable databases is not something that's easy and can't be done quickly.
Would be interested to understand the barriers to applying self-teaching to a broader problem domain.
"Having the ingredients prepped the first time you embark on a new recipe makes it way more approachable"
I agree and I'll single out npm.

It's a great tool but it must be used with event greater care. You can `npm install` a package and get dozens of packages requiring packages. Before you know it your little app has 100's of dependencies.

On the flip side, I use `npm run` instead of writing simple bash scripts. Why? Because everyone I work with runs lots of things this way. Doing so ensure's they'll know where to look for all the stuff they might be able to run.
The website is a commercial one which accepts payments and vends licenses (https://zenaud.io). So some kind of dynamic website is necessary. Printing to static html is a file (51 LOC) with a single function definition.

I'm pretty sure just reading the docs on the Hugo or whatever takes longer than it took me to write the it :)
Would be interesting to see this in comparison to other countries. My guess is that their spending as percent of government revenue is much much lower.
Which offer is richer? Which team did you get a better feel from?

I don't have any experience with the culture of either, but I would imagine in an organization that large there will be teams at Facebook that will seem more Googley and more teams and Google that seem more Facebooky

Other than prestige (which I think they are on equal footing) I don't think generalizations of the entire organization will be to helpful.
Anyone who believes that they can gain sympathy for their cause in a country by indiscriminately killing people there is misguided.

When someone's policy is mass murder that would happily target me, it's hard for me to muster much interest in whatever point they might be trying to make.

So I'm perfectly happy to say US policies in many countries have been greatly harmful, and also give a big middle finger to people who want to kill me.

Another vote for Pimsleur, at least for quickly acquiring a basic set of phrases and words for travel purposes. I've used 5 different Pimsleur courses (Turkish, Italian, Greek, Russian, and Dutch) in preparation for various international trips. I've found going through just the first 8 or 10 lessons is enough to get the necessary survival phrases firmly embedded in my memory. Pimseur also offers lessons intermediate and advanced courses that can take you to greater fluency, but I've never pursued any courses that far. If I really wanted to work toward fluency in a language, I'd probably start out with a different method.

As others have pointed out, Pimsleur is oriented strictly to the spoken language, so if you need to be able to read the language, it would make sense to supplement it with separate written course materials, especially if the orthography of the target language is particularly different than your own (e.g., Greek and Mandarin).

On a side note, I also find doing a 30-minute Pimsleur course to be a great mental exercise. Recalling the phraes and responding to the prompts, I literally feel like rarely-used parts of my brain are getting a workout.
Blue Apron has multiple problems. 1. Once they teach you cooking isn't hard you will do it on your own. 2. Most grocery stores of all levels have meal kits now. 3. If you buy a mandolin(knife skills are for tv shows and culinary school) and safety glove you can go from raw not chopped ingredients to plated hot meal in under 20 minutes..
This isn't an app, we're talking about here. These are people's lives.
I've used i3 for many years now. It's wonderful to see a tiling WM for Wayland with near feature-parity to i3. It probably makes it much easier when i3 has avoided feature creep, and has clean readable code.

Yes, totally uninformed. Blockchain is not for establishing consensus, but for

Sexism is more than "safer to talk shit to a woman compared to a man" as you say in your article.

Sexism comes out in target choice, and the strength of which ones chases their prey, and the vehemence of attacks.

I do strongly believe that Cuddy was overly punished for being a woman, and being prominent in the field. Everyone loves when the "high and might" come "crashing down" -> the underdog stories and the desire for retribution are sought after more powerfully than (a) justified and (b) end worthiness of the goal.

I don't think anyone can honestly say that this has improved the field and made science better. It just means now that there is money and recognition to be made being attack dogs. That's hardly better.

As for Gelman, he wasn't portrayed in a great light, but I think it is fair. He's willing to encourage incivility and outright sexism and hostility as long as he doesnt have to talk to someone he disagrees with. That's the baseline definition of a coward there. And yes, I would discuss that with him in person and call him such a thing to his face.
A senior poker player showing another in need of help how to play the game so that they have the best chance of coming out ahead is precisely the most sympathetic thing he could do.
Customer Analytical Record / Feature Engineering Store

One customer column, tens of thousands of attribute columns.

If you need everything about a customer it is a single, O(1) fetch operation which makes it perfect for driving chat bots, call centres, websites, operational decisioning engines, dashboards etc. Almost every large company will have one of these.

You can't really do it in relational systems properly because (a) you hit the column limit, (b) often it is sparse i.e. lots of NULLs everywhere, (c) you need this system to be distributed since it often gets a lot of load.

The observed pattern exactly fit into a previously established hypothesis and was totally unexpected. I did not slice and dice the data with multiple statistical tests. The only way it could have been related to p-hacking is that I am familiar with a bunch of biological theories and could recognize data patterns that are compatible with any of them. So, maybe a Bonferroni-type correction of 30-70x (i.e., number of theories my internal neural net has been trained on)?
I kinda do the reverse. When I'm at the store, I buy a couple random things. Then I go online to find a recipe.

If I can't find something, at the end of the day, pretty much any piece of food seasoned and grilled will taste good.
Someone thought going vertical was a good idea. Which might be after you're mature and profitable and going vertical can be shown to reduce costs. Someone got ahead of themselves though. Now they are beholdened to the cost of the ranch raised meat. What if it's more than other suppliers?!
> When I used Django, it would randomly "go down" when some library changed on my host.

I haven't had that problem. Django is alright IMO, if a little "heavy" on machinery. I'm not crazy about it, but it gets the job done and I do have a soft spot for python :)
Can you give examples? To me $10 seems low. Guess it depends what you mean by "high quality". Are we talking prepared or raw ingredients?

If people only wanted 2 kb text pages, it'd be a different story. But rich media is often what people want, so it makes even an information lookup on native Yelp expensive. Once you bring in rich media, 1 MB of JS is very minor, and JS can be used to optimize your rich media downloading.

I would guess that grocery stores have been hesitant to implement any new model which allows customers to avoid the high margin checkout item goods and high margin prepared foods. The web order / quick pickup model shows they are slowly coming around in some ways, however.

For the model you describe to work, they'd have to charge quite a bit more for the ingredients that one would pay simply buying them yourself (or, again, totally forgo the prepared food high margins). Premium prices for "ingredients + recipe card" would trigger price inflation complaints from mainstream shoppers who aren't comparing the option to blue apron but taking an extra 15 minutes to get the items themselves.

What's that term for the profits an established player has to sacrifice to compete in a new market?

If we're killing off stories because of the behavior of trolls who don't like them, that seems like a victory for the trolls. Maybe it's the trolls who are the problem, rather than the targets of their misbehavior.

What sort of restaurant serves meals this cheaply? Here in UK I have a subscription to Hello Fresh at £49 for 5 meals for 2 people. So.....let's make it a round £5/per meal/per person.

For £5 you can get.....a frozen burger and a pint of pepsi from a local pub? I can't think of any restaurant that would have starters this cheap, much less mains.

The demand for me is that it's fresh, delicious and I learn a lot about cooking while making it - it's been 100% worth the money so far.

> I would argue that immersing yourself in a native environment is hardly a simple thing. It's expensive - often in money, but always as an impact to your life. If you have a job, or spouse, or kids or pets, how does this work. I've actually done this and each one of these things is a huge problem. If you're a young, single person who can work remotely or doesn't need a job, then maybe, but that's not most people. If you do need a job, getting a visa to work in a new country is also non-trivial and often impossible.

Too many ifs, sorry but those sound like the same excuses people say when they explain why they can't travel (more). You have to figure out what your priorities are, and if you really want something you'll find a way.

>It's also not just on you to "force yourself to speak a language". You need someone to listen to you.

Easy. Just go buy some food. You don't need much language skills for that task and it's a start. Or if you are single, go on a date with someone who doesn't speak your language (this was personally the most efficient way for me personally). You overcomplicate things. Your rate of learning a language is proportional of how uncomfortable you want to be. I've seen people studying in language schools for years until they get everything perfect and they can't even maintain a basic conversation. Overall this idea applies to all learning: "to become a master you should be willing to be a fool", i.e. make mistakes.

> It's also very hard to pick up vocabulary implicitly from conversations unless you have some base. My German is good enough now that if I don't understand a word I can ask them to rephrase it using other words and I can often get it. Children can do so just from environmental and contextual input often, but it takes them _years_. So you still have to spend a lot of time studying and building vocab on your own in order to try out.

Most of the information is communicated via non-verbal channels: body language and intonation for example. Using your intuition is crucial here. The rest is basically pattern matching. A single word you can understand from the context. Once you understand > 50% words in a sentence, you can derive the rest from the context and then it becomes a self-reinforcing learning system.

Well, children also don't have the same intellect as an adult and cannot apply more sophisticated learned cognitive techniques.
WPA2 KRACK in 5 Mins
There are a number of sources that refer to the Space Shuttle Orbiter as a 'flying brick' and that it doesn't fly as much as 'falls with style'.

I work in a Regus office in CA, and they are constantly having issues. The washers/dryers are always broken, the AC has to be fixed every other week, yesterday they had a plumbing issue and the water was out so no one could get the 'free' coffee let alone use the bathrooms. There's almost always something not working, however most the times it's something relatively minor and overall it's been a decent experience. I imagine WeWork would probably have those things ironed out for a lot more $$. The other thing is you have to pay extra to turn on AC if you want to work at night or on the weekends, which thankfully I haven't had to do with my current company.
For what it's worth, I largely cosign this critique of how HN is moderated.

I think there's merit to the suggestion that snarking about how unwelcoming HN is to industry minorities is counterproductive. But I don't think HN's institutional commitment to being more welcoming to industry minorities is exactly pellucid.
Sorry, that comment was a bit flippant -- I have huge respect for the Rust language and community and agree that the left-pad-debacle is pretty unlikely to happen there.

What I meant is that I consider static blog generation so simple that you should be able to do it yourself. I hope that doesn't come across as arrogant, above I allude to the fact that for my case, it took 51 LOC of python to get it done (admittedly harnessing the machinery of the existing, dynamic website).
> If you buy a mandolin(knife skills are for tv shows and culinary school)

I’m happy that a mandolin is working for you, but there is a lot more to knife skills than slicing - there are a lot of foods and cuts that a mandolin can’t do, and they aren’t difficult or unsafe. As long as you don’t feel a need to be as fast as a line chef, you can do pretty much any cut with about 5 minutes of practice.

That's like saying "if puzzles came already put together people would buy more".

They are marketing their product at people that want to do the prep, the cooking, the whole deal, but don't know where to begin. I loved my few Blue Apron boxes that I got. It was exactly what I expected and wanted.

There is a market for what you describe, but it's not what they are trying to solve.
Yes it does, it's just more labor-intensive.

> many cases of vote solicitation [...] and their posts even make the front page

That last bit is the critical one. Vote solicitation that doesn't go anywhere is an annoyance, but fake upvotes getting otherwise lame content on the front page is a threat. If you (or anyone) see cases of this, I wish you would send them to hn@ycombinator.com. We investigate, and can usually figure something out one way or the other.

From my perspective—but of course we don't see everything—HN's anti-voting-ring software is now so strict that the main thing we have to do is turn it off when a submission is good enough. It's not uncommon for there to be a high-quality project that someone has put months or years into, and then naively tries to promote on HN (edit: I mean by asking friends to upvote). Often people think that's what they're supposed to do. (If you think the opposite should be obvious, try communicating anything to a large-enough audience. The vast majority never get the message.) If we didn't override the voting ring detector in such cases, some really good work would be lost to the audience here, which wouldn't benefit HN. Of course this is rare enough; most ring-voted submissions aren't very good. But years of working on this problem have taught me that the best voting ring detector would not be one that penalizes submissions; it would just turn all ring-votes into no-ops.
If you are unable to observe a thing directly, and instead could only see it through a distortion lens, would you want the opportunity to look at it through multiple different distortion lenses instead of just one?

The world we know is largely constructed by semi-conscious and sub-conscious processes, from world building processes (such as how the mind filters and modifies information to construct our reality), to conclusions we make about the world, ourselves, and what is possible (emotionally motivated reasoning, decision heuristics, predictive modeling).

Google deep dream provides interesting insight into psychedelic phenomena, and hints at what is changing in the mind’s world-building process when on those substances.

When it comes to MDMA, because it so dramatically changes emotion, it can also dramatically shift reasoning and thinking heuristics that unconsciously originate from emotion. This can transform beliefs that you once took for self-evident fact, into things that you now realize represent how you feel more than reality.
