I want to believe Newgrounds can recapture a large amount of illustrators who have Patreon accounts and large amounts of work, because they have excellent categorization features and hosts both SFW/NSFW stuff.
Similar situation in Finland; we had a baby over Christmas two years ago. We spent a few days in a private room with a checkup on the baby/mother around noon and 6pm.

We paid €250 or so for 3 or 4 days (genuinely can't remember I guess my sleeping wasn't so great. Oops!) for the three of us, so it wasn't free, but it was pretty cheap.
It's unclear. Trouble is none of the powers seem to have been necessary in about a century, so it probably needs exploring in court.

Or formalising powers in some new legislation, which will eventually result if people start to treat committee summons as optional. This is probably well overdue. :)
It's quite silly to say something is false without providing a logical reasoning. And what is false about that statement, that it will absolutely not hold its value? Sure, but it wasn't my main point.
Read the quote again. It's opt in. So doesn't matter about the permissions they were just trying to avoid yet another nanny nag.

People calm down. This is just a bunch of socialist politicians grandstanding against the hated megacorp du jour. There's more important things to worry about than opt ins or whether Facebook should be forced to give its data away for free to competitors (oh my what a scandal API blocking is) or whether sensitivity to bad PR is evil. Also is it really the normative PC position now that collecting data is bad but giving it away free to competitors is good? Wow. USA is getting bad but don't see how or why anybody does business in Europe with it's proven ability to characterize normal business competition as Evil and criminal, particularly if done by American companies. The apparent goal is to stay small artisan inneficient and Luddite. Very socialist and very European.
I know your post is sarcastic, but some of these (eg. 2) are real concerns for large enterprises. Enterprises want not just a product but a solution and that includes support and all that comes with it.
This is exactly right. Mortgage/debt represents risk. Many people do the math on potential returns, but calculate risk as $0, which it definitely is not. I think it helps to consider this transaction in reverse. If you had a paid for house would you mortgage it so you could put that money into an investment account at Schwab? Almost certainly not.
Hell yeah.

I have been involved with companies that have wanted to do things with Facebook non-personal data (eg. pages) and could never get anybody to talk. Some of these were little companies in the "flyover" states, one of these was pretty good sized in L.A.

When you see them playing favorites you see another thing that S.V. will struggle with for years.

One reason NYC is so important for finance is that people go have lunch and trade insider information without leaving a paper trail.

In the same way S.V. companies circle jerk each other giving each other special privileges, staging fake acquisitions so sons of investment bankers can make it look like they were successful startup founders, etc. Sometimes they even get a stooge to come in from a place like Saudi Arabia or Japan to buy them out so they can tell the people who put money in their fund that they made money. Those folks will lose a lot of their A.U.M. but they probably get paid off in some other way.

S.V. doesn't have any problems that wouldn't be solved by opening offices in the flyover states. But there are two things about those people.

They don't listen

> I'll assume every morality is invalid. Instead base ones intent on the harms their actions cause.

Assessment of harms depends on a value system; you can't escape the need to choose a morality.
And even if you have to use some other tool (Redis, Cassandra, MySQL!), you can access it from Postgres – https://wiki.postgresql.org/wiki/Foreign_data_wrappers

PG has some warts, and the config defaults are really more suitable for a RaspberryPI rather than production use(so people sometimes get the wrong impression out of the box), but it is rock solid and can support so many different use-cases.

It's one of the few pieces of software I could feel confident that, due to the way it's designed, my data will still be there even if someone yanks a server power cord.
Even after arguing in favor of XHTML here in another comment, I'd like to make a separate "modest proposal":

What if we had a limited kind of markup as part of Unicode, such that all Unicode text could be "marked up", entirely-portably, such that as long as you aren't rewriting the Unicode representation, you're preserving the markup?

Unicode already handles many kinds of markup. We just don't tend to think of these features of Unicode as "markup"—even though many of them have one-to-one equivalents in markup languages!

Most obviously, you've got newlines, the plaintext equivalent of the HTML <br> tag. If Unicode was "just" about representing text, newlines (and horizontal/vertical tabs, non-breaking spaces, zero-width non-joiners, etc.) wouldn't be part of it. These aren't text; they're instructions to a text layout engine, for where to put the text. They're markup, just as much as an HTML <center> tag is!

Less obviously—but more flagrantly—Unicode has the BIDI LTR/RTL instruction codepoints, and support for storing and representing a https://en.wikipedia.org/wiki/Ruby_character gloss of a given character-sequence embedded alongside said text.

And because of this support, Unicode font rendering engines already have everything they need to be able to render a given "meta-instruction" codepoint that makes a given "run" of characters bold, or italic, or small-caps, or strikethrough; or to indicate that a given run of codepoints should be considered a list item, or even a semantic "paragraph" or "heading."

It's my understanding that the maintainers of the Unicode standard would balk at standardizing this kind of markup within Unicode. But, if all this is possible at the Unicode-parsing level, then why not just create a separate working group who will maintain such markup codepoints as a Unicode Private-Use Area, and then get font-rendering-engine vendors to support said markup codepoints?

---

Side-note: the result would be a lot like creating Unicode-codepoint equivalents for ANSI escape sequences, wouldn't it? In fact, I would imagine that pretty much every common ANSI "Select Graphic Rendition" escape sequence would make sense as a Unicode markup codepoint, save for maybe being translated to prefix-length or per-grapheme-cluster-paired forms rather than being modal switches.

And oddly, I think that such SGR-equivalent codepoints would be within the spirit of Unicode. Unicode wants to allow for the digitization and standards-based preservation of all historical text. Well, how are you supposed to preserve the text-art sent by an 80s BBS, without being able to represent (at least) fg/bg color changes? Unicode already decided to standardize the DOS box-drawing characters for exactly this same reason!
You are what you repeatedly do.

It's very unlikely that someone who's spent their entire professional life being one way flips a switch after tenure.
Not to mention how expensive that flow chart looks.

Just from a camera perspective, RAW capture from digital cameras can eat up space over time. At ~60MiB per image on 24MP cameras and a usage rate of 2000 images each year, you consume ~120GiB of storage each year. Video and post-processing storage adds further.

Cameras increase in resolution, better sensors, ...
Get someone to manage it, take a nice, comfortable salary and start enjoying yourself. Out of respect for the rest of us schlubs DO NOT get another job.
Seriously though this is true especially from their users.

It is never just PostgreSQL is a great database. It’s always that MySQL, Oracle, MongoDB and the hundreds of NoSQL databases are all unusable junk with no unique benefits.
Sounds about right to me! One of the companies I consulted for had a billing department that insisted people pay their utility bills by check. They said "this is the way most of our customers like to pay".

But what they really wanted to say is "we will have to repurpose 200 staff who process these checks and mail out statements, and they're all 30 year veterans, and I don't have the heart to tell them they're fired even though they are the sole reason we lose money"
The person at a McDonald's drive-thru is an actual employee though, they're paid for all their time on the job, and they can't just refuse to serve a given customer. A Lyft or Uber driver is a contractor, and is legally allowed to refuse any individual ride.

If they couldn't refuse rides, then saying "pay them for all the time they're in the app" makes sense, but that's not the case. Since they can refuse rides, it doesn't make sense to say "you must pay them for all the time they're in the app", especially since a single driver can be active on both Uber and Lyft at the same time.

One could argue that drivers should be turned into part-time or full-time employees, at which point yes they'd have to be paid for their idle time, but that's a different argument.
I have had bad experiences in the past, maybe not on the scale of [1], but quite close. The newer drives are better (adjusted for age).

I would generally agree, though there are unfortunately limitations imposed on you the moment you start using partitioning with PostgreSQL (foreign keys remain to be a big one).
The Han Chinese has the tradition of keep the official account of histories:

https://en.wikipedia.org/wiki/Twenty-Four_Histories

That is the official account of the Chinese history by the succeeding dynasty to record the important personals, their lives and big events from the previous dynasty.

That is a very unique tradition though. The fact that the ancient Chinese does recognize a chain of dynasties and heritage and succession therefore, is unique to China, not by other Western countries.

Yes, they do, and it makes sense to do so. You want to point others to the related work that has been done in the topic and it's likely that your lab has done a lot of this work.

Of course other groups have also done related things, and you should cite them as well to create an honest image of the research landscape.

In the case the OP mentioned, this is how a lot of research is carried out. The main part that sticks out to me as as scuzzy is that he took first author without being closely involved in the work.
Would this be the same sort of "negative mass" required to make the Alcubierre Drive or similar things work (at least on paper)?

Are you running at a scale where a single master DB isn't sufficient?

Because nowadays you can get servers with about 192GB of RAM and 32 CPU cores.

Clustering seems like one of those "what if"[0] scenarios where maybe if you were operating at roflcopter scale you might need it but for 99.9999999999999% of cases, a single master DB is more than enough -- at least with a well designed SQL db like Postgres.

I invite you to plug in negative mass to Einstein's famous equation. Negative mass is what is required for faster-than-light travel.

What is needed is a craft that has a normal, positive mass shell that contains and holds an equivalent amount of negative mass, thereby giving the entire craft a net mass of zero, allowing unlimited acceleration.
It is not as expensive as hiring the wrong person.

Better Worlds – a collection of optimistic science fiction works
Yes, you did inasmuch as you said people should be required to build parking.

Person A lives in a nice old house in a quaint neighborhood built before cars. They park their car on the street.

Time goes by. More people buy cars, and more people move in. The street parking becomes full.

Person A is outraged that their ability to park on the street is gone. They demand all new homes have off-street parking.

Newcomer to the neighborhood, say some weird hippie cyclist who doesn't own a car (like me), has to pay more for their home because the land that could have held 8 homes now holds 5.

Their property taxes help pay for person A's parking.

Of course, it doesn't work that well. Off-street parking _still_ takes up street space for access.

If people want parking they will demand it and pay more for it. Some people want helipads but we don't force everyone to have a private helipad in case they run out of space on the street for your helicopter.

Why do people demand parking minimums? Because the street parking is full.

Interestingly, Asia-Pacific dominates the graph: specifically, Chinese companies seem to have been on the largest debt binges with total amounts exceeding their American and European counterparts.
It's missing nuance.

For most companies missing out on an excellent hire is worse than hiring someone subpar.

Distributed transactions, raw filesystems, nice graphical admin tooling with reporting, stored procedure development and debugging capabilities (pgAdmin is nice but that is about it).
Seriously. After using Oracle for 15+ years, moving to Postgres has been amazing. Just moving from clob to text has nearly brought me to tears of happiness. Nearly all of our complex sql queries are simpler in postgres. The documentation is light years better.
I agree with the other comments. I'd add that just because the end product can be easily seen to be a complex mechanical artifact, doesn't make it inherently more complex to manufacture than something solid state. A lot of complexity goes into making the solid state device too; it just happens out of sight in the fab.

It's (somewhat) the same situation as with EV and ICE automobiles. The engine and drivetrain in a modern ICE vehicle is extremely complex. Much more so at a macro level than EVs. But we're actually pretty good at building reliable complex mechanical systems. More things shift to solid state over time but it's a long process.
Arguably people need a home more than they need a car even in the most extreme cases.

I fear that earlier stage companies will read posts like this and implement it blindly without considering the big picture, which is:

- Stripe is a large and resourceful company with a relatively large engineering team. They can afford to have people focused only on things like this.

- The demand to work at Stripe is high. Therefore they can afford to have a long, grueling interview process. Most engineers will not want to go through a 7 step hiring process at a low prestige company.

I feel like the discourse might be missing the point, starting at why we are here: Tumblr was removed from the App Store. Tumblr is a website but without a doubt it thrives on being a mobile app on iPhones and iPads. This ended up happening because of course the NSFW content on Tumblr is notable, even if we don't know the actual scale. Lots of pornbots and what not.

What concerns is this: Well and good that Apple says "we don't host pornographic communities on our app store" and Oath immediately sacrificed the lamb to appease Apple. How is this a problem after so long? What if I told an Apple executive the exact same content manifests in Twitter and Reddit?

Evidently the app stores have no interest in hosting NSFW artists and the open web should step up.

WHAT WE DO

Locate.ai predicts where retail stores should open, and ultimately use our a.i. models to optimize value of real estate. We're first movers in this $2T retail sector.

-----

WHY LOCATE?

i) You'll have ownership of solving very challenging technical problems,
ii) Tremendous personal growth potential by joining an early-stage scaling company, and
iii) Our industry -- proptech (i.e. real estate tech) -- is blowing up. More VC money in this industry than ever before, and real estate is the largest asset class in the world -- however, one of the most antiquated. It really is time to stir the pot, and Locate is first movers in solving one of the biggest problems in real estate: what is happening to retail?

-----

WHAT YOU'LL BE DOING

Depends on your background / passion, but open positions are backend engineer, data engineer, and full-stack engineer. For brevity, back-end/data engineer will work on all things geospatial data related that's used for our a.i. models, and full-stack will be creating customer-facing products.

-----

WHO WE ARE

Founded by Stanford engineers with a team of retail / industry experts, we are an early stage, VC-backed company based in downtown San Francisco, CA. Half the team are founders or ex-founders.

Psychology needs to start moving away from trying to categorize things into these arbitrary fuzzy human buckets ("emotions") and toward being able to predict things. If someone is diagnosed with "X", the most pressing question is now: how is this diagnosis useful to that person or society? Is the person trying to change from the state they are in to a different state? If so, does knowing they are "X" or feeling "Y" help with this goal? I would argue that for the past few centuries, no, this process hasn't helped very much.

For instance, consider the DSM description of borderline personality disorder:

"BPD is a pervasive pattern of instability in interpersonal relationships, self-image, and emotion, as well as marked impulsivity beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:

- Frantic efforts to avoid real or imagined abandonment

- A pattern of unstable and intense interpersonal relationships characterized by extremes between idealization and devaluation (also known as "splitting")

- Chronic feelings of emptiness

- [...]"

You get the point. You have to meet five or more of the listed criteria. Not four or more. Not six or more. But five or more. There's a lot of ad hoc, informally specified, subjective criteria that probably have no reproducibility if ten different psychologists were all told to independently specify which of the above criteria a given patient satisfies. See the recently published update on the reproducibility crisis: https://www.the-scientist.com/news-opinion/half-the-time--ps....

In general, psychology doesn't seem to be based on many of the lessons acquired in the physical sciences over a very long period of time, and there doesn't seem to be much math involved. Open a textbook on quantum field theory and open a textbook on psychology, and notice the main difference between the two. Data on people is scarce, often biased, improperly sampled, and study results are frequently cherry-picked to promote some sort of predetermined narrative about how the human mind works. The human brain is one of the most complex objects in the known universe, and pretending that we have a modicum of understanding about this object is the type of overconfidence and hubris that will lead to centuries of inadequate mental help for people that need it.

What's the solution? Start collecting data and start trying to quantitatively predict things. I have no doubt that machine learning will fail to predict human behavior, but I also have no doubt that it will fail much less drastically than the current approach. Outcomes need to be strictly measured. In this case, I don't think we are as interested in "explanatory" science as we are "predictive" science; i.e., we don't care as much about why the blackbox model works as long as it improves people's lives. Consider for instance the current system of categorizing personalities: the "Big Five" system (OCEAN). Why is this still a thing? Any sort of primitive GBDT would almost certainly perform better than this, so it's a mystery to me why these crude systems are still being used in the mental health industry in 2018.
