OP's probably referring to induced demand [0], or something similar to Braess's paradox [1].

But I see your point though. If people are incentivized to share a car then that might reduce the load.

That said, my suspicion is, once you take the driver out of the equation, you can do so much more than just ferrying people. E.g courier/shipping services, or mobile food stalls (food truck that sells food while moving on the highway, once engineers figure out how to safely and autonomously speed match two cars), etc. The induced demand may be greater than the savings from ride-sharing.

What I find most interesting about this is directly from the first line of the company description in their S1:

Yet the one instance where they actually own and sell a camera (i.e. Spectacles) instead of leverage someone else's (i.e. smartphone) it's a massive failure.

Do you have any suggestions on how to find the right people when they aren't using social media like LinkedIn or Facebook? I know a number of managers at a local Fortune 150 company that don't use those tools and I've always wondered how I would find their contact information if I didn't already know them.
I am not sure I see a huge distinction between the two. One is bullying the industry press to give you favorable reviews. One is bullying the industry press to avoid publishing stories that paint you in a negative light.

Either way, Apple has been accused of both.
I've had certain forum software sometimes as a side project, sometimes as my man full time project, during the last 7 years. So yes there's lots of work. But in my case lots of time was "lost", in learning web development / React.js / Angular / Dart / other stuff, and porting from the-wrong-technology, to another the-wrong-technology, and building the wrong things that no one wanted.

I think the Discourse (forum software) team were a few people, like, 3? and they spent some year(s) developing the initial version of Discourse. So ... yes some weeks/weekend? for the initial version, and ... >= 3 years ? for a "real" version :- P

To add something I think is overlooked, many people from China feel very unsafe in the US due to all the news about mass shootings. The previous generation of immigrants came for a better life and a sense of safety is an important part of that.

China:
+ Cultural familiarity, closeness to family.
+ High pay for engineering.
- Pollution
- Lack of work/life balance culture.

US:
- Lack of safety.
- Culturally lost.
+ Higher pay
+ Better natural environment.
+ Better future for kids. Schools & stuff.

Censorship is a minor concern for the most part except for political activists. It's arguable that that the US is becoming more draconian in this regard, especially due to police being able to do whatever they want once they decide you're guilty of something.

Not OP, but my insight: Adult entertainers use Snapchat as a distribution channel for their own self-made videos.

This sounds quite a bit like a probabilistic version of the Collatz problem (https://en.wikipedia.org/wiki/Collatz_conjecture).

If you know the name of the field trial you should be able to opt-out on the command line provided you use the correct syntax with the --force-fieldtrials option.

However it was not established whether or not field trials (A-B testing) was even the problem merely that they existed on the chromium processes. Even the stable version of the browser will likely have these options on the command line.

Yes, it’s so easy to “click around cities” and “do street view” on a paper map. It’s amazing that Google Maps even exists given the magic paper maps we already had.

All my examples are calls into Kotlin from Java. With Hadoop, you're implementing interfaces that the framework instantiates via reflection and then the Java framework calls the Kotlin code. With Rome, you're creating Kotlin objects that implement a Java interface and then they're called from Java code.

Are you speculating or have you seen this clearly? Personally, any way you frame it, it comes down to a lack of focus; failing to act before the lens of public opinion shifted.
The tuition waivers are mostly government funds. This tax would force universities to pay students significantly more so that they can afford basic living expenses, thus drastically reducing the amount of science that can be done at present funding levels. If goverment caps the stipends, it would prevent many students from pursuing graduate degrees in the US. Those most affected would be those privileged graduate students -- those likely to have beaten the odds purely on merit. These factors would tend to drive top faculty and students to other countries. If science funding levels were boosted to compensate (hah), it would all be a meaningless accounting trick.
I do occasionally go back and add formatting, especially when writing a longer article. I also often add links later, or write [link text]() and fill in the URL later so I don't have to stop and find a reference I know exists.

Brain and NNs, at least in the first visual cortex layers and the first perception layers accordingly, are doing the same thing - building optimal sparse coding for the body of imagery they've been exposed too (in general it isn't limited to images, it is just that our knowledge for image processing seems to be a bit more advanced). There are works from 199x proving that Gabor kernels - which form the first layer in the visual cortex and which (or very similar) happen to emerge in the first layers of well trained NNs too - are optimal for a wide class of image inputs (edge density, etc.), basically the class of images naturally surrounding us. That optimality provides for a good explanation of their emergence in NN.

It seems to be a natural speculation that the further layers of visual cortex/brain and NNs are subject to similar optimization, and thus they would have similar kernels. I think psychedelics somehow stimulate these deep layers to massively fire without waiting for the normally required input from the eyes to propagate to those layers to selectively fire neurons in them.
Not to mention his entire rant on maps losing search items when you pan is just wrong.

Going Fast with SQLite and Python
So in essence it's a lot of work for a small functionality gain?

There are some things that are inconvenient to do without window functions, but my primary use for them is simple optimization. Most of the cases where I've used window function in postgres, the query would be trivial to rewrite to use a subquery instead. Window functions always led to a much faster query that scaled much better over large query sets.
Honestly, the best thing Snap can do to control their destiny is gut headcount by 2/3. If they bring their costs down so they aren't burning cash, they still have a highly engaged user base that is stable with decent advertising revenue. If they aren't burning cash like a wildfire, they can have some time to think strategically to build better user growth and engagement. Spiegel needs a strong COO like Sheryl Sandberg to put realistic controls on expenses.

As it stands now they are basically pulling a Twitter.

Or broken into 10, 20, or more tweets.

Which, to me, is the disappointing thing about the new character limit: it does nothing to address this emerging usage pattern, one might even say emerging form of communication, of the tweetstorm.

It seems pretty clear that tweetstorms enable a certain mode of marshaling thoughts and communicating them in an off-the-cuff way that blogging services never identified or understood. And yet Twitter's product org doesn’t seem to understand it either.

True, the continent of Europe (10.2 million km^2) is larger than the United States (9.8 million km^2), but the context suggests wskinner meant a comparable geopolitical entity such as the EU.

>NASA was talking about fostering commercial space launch companies before SpaceX was founded

Well right, except in that scenario "commercial space flight" was them continuing to hand dump trucks full of cash to ULA. Which wasn't really commercial in the sense we're all talking about commercial at all. It was a giant government contractor who essentially acts as an extension of the government who was interested in maximizing profit, not innovating. It looks, and would have looked, absolutely nothing like SpaceX. No signs indicate they're even ABLE to provide the same relationship.
Oh yeah? Don't know about the US, but certainly here in Europe criticism of Islam is verging on thought crime these days. If you want to know who rules over you find out who you are not allowed to criticise.

O Divine Poesy
Goddess-Daughter of Zeus
sustain for me
this song of the various-minded man
who after he had plundered
the innermost citadel of hallowed Troy
was made to stray grievously
about the coasts of men
the sport of their customs good or bad
while his heart
through all the sea-faring
ached in an agony to redeem himself
and bring his company safe home

Vain hope - for them
for his fellows he strove in vain
their own witlessness cast them away
the fools
to destroy for meat
the oxen of the most exalted sun
wherefore the Sun-god blotted out
the day of their return

Make the tale live for us
in all its many bearings

Really? It'd have a HUGE impact on my life.

Nearly every aspect of my social life is planned on Facebook. It's the one place where nearly everyone I know are. Facebook, for me, is really just the best event planning tool in existence.

I'd also instantly lose contact with a bunch of acquaintances and friends. I've moved around quite a bit in my life and Facebook connects me with those people. When I travel it's the platform I use to reach out to the people I want to catch-up with. It'd be a real bummer to lose that.

It's true that the news feed aspect of Facebook is something I wouldn't miss. It's something I never use anymore, politics has taken care of that. But all of the features around it ARE things I deeply care about.
