Counterintuitively enough liquid ammonia packs more hydrogen than liquid hydrogen per unit volume - also it condenses at -33C (-27.4F), so it actually wouldn't require cooling once in the air.

It can be burned in a gas turbine, but for now the NOx emissions are pretty horrible.
The rental contract includes a provision for either party to terminate the lease with notice.

Of course, there's no penalty if the landlord initiates it, but you lose your deposit if you do.
Exactly. Especially on a desktop operating system. On iOS at least you can have applications give notification over things like screenshotting i.e. Wickr, but if you are on desktop it's stupidly easy to retransmit or download the contents of an email. Maybe Gmail is just admitting that this is the reality (which it is).
1kg of kerosone can be kept in a plastic tank that weighs nothing. 1kg of hydrogen has to be kept in a pressurized, pure-lead 70kg bottle, and even then hydrogen will diffuse through it in just few weeks. So to take 1kg of hydrogen with you you're taking a lot of weight in the tanks too.

Yeah.. Didn't even need to load the article. You're passing the index as the radix. Makes sense
TL;DR, parseInt() takes the number base as a second argument, and map() passes three arguments (value, index, whole array).

Using directly like this a function with map() is just incorrect, the correct way to do it is:

['1', '7', '11'].map(x => parseInt(x))

> Running in a VM requires an additional Windows license. I'm not even sure if you're allowed to use an OEM license for a VM, or if you need proper retail or even one of those "VDA licenses".

Of I understand correctly, and I might not, you either need an Enterprise license or a VDA subscription and you need the user PC that will access the VM to also have its own desktop (pro or enterprise) license if you aren't using a VDA subscription x (that it, it is a license precondition for the VM license that the PC has its own license in addition to any licenses for VMs.) Windows desktop VM licensing seems to be oriented around corporate VDI setups, not desktop-on-desktop local VM use.

This has less to do with "parseInt" than it has to do with "map" in JavaScript. It doesn't work exactly like .map in Java, Ruby, Elixir, etc., because ".map" in JS also passes in the index, and the full array.
Engines don't stall, planes do. Plane stalls are about aerodynamics, and nothing to do with the engine.

Abstract:

> Adaptive information seeking is critical for goal-directed behavior. Growing evidence suggests the importance of intrinsic motives such as curiosity or need for novelty, mediated through dopaminergic valuation systems, in driving information-seeking behavior. However, valuing information for its own sake can be highly suboptimal when agents need to evaluate instrumental benefit of information in a forward-looking manner. Here we show that information-seeking behavior in humans is driven by subjective value that is shaped by both instrumental and noninstrumental motives, and that this subjective value of information (SVOI) shares a common neural code with more basic reward value. Specifically, using a task where subjects could purchase information to reduce uncertainty about outcomes of a monetary lottery, we found information purchase decisions could be captured by a computational model of SVOI incorporating utility of anticipation, a form of noninstrumental motive for information seeking, in addition to instrumental benefits. Neurally, trial-by-trial variation in SVOI was correlated with activity in striatum and ventromedial prefrontal cortex. Furthermore, cross-categorical decoding revealed that, within these regions, SVOI and expected utility of lotteries were represented using a common code. These findings provide support for the common currency hypothesis and shed insight on neurocognitive mechanisms underlying information-seeking behavior.

>more awful movies while trying to argue that 'this is what people want.'

Moviegoers don't want the same old thing. But they also don't want this weird Lynch/Cronenberg (snobbish Godard) stuff. We should have books and films with enough cultural cachet that almost everyone should be experiencing them simultaneously (ie, there's too much fragmentation). But there should be small, independent, unique voices.

So when it comes right down to it, what we really want is something comfortable (known) that doesn't quite feel that way (but not too much) and everyone shares as a cultural touchstone, but one which is unique and special to each individual. This seems to be the real problem we're running against.
I'm always curious how the Project Managers working on these projects think about posts like these. It's a very public call-out, effectively saying "this product is not what they say it is and is dangerous." Especially when it's obviously true, I'd be curious if anyone here can speak to the mental state of someone on the receiving end.

For example I was publicly put on blast for something that was false about me. So in that case I just blew it off because it was wrong, and no reaction was really necessary. It was still very stressful though personally and for my family. I wonder how these product teams across Google and FB primarily feel in these cases.

I like posts being out there like this. I expect many non-technical users will get the wrong impression about confidential mode. Impression is different from the stated words and can be filled in by our subconscious thoughts about the space between what is said.

When words are explicitly said it can cause people to think things through.
First off, there are plenty of older Windows applications that currently exist that aren't going to get a port to a modern web app any time soon that work perfectly fine with Wine; even Microsoft doesn't support running Windows 3.1 programs anymore. You could argue that nothing from that era is worth preserving, but are you saying that applications like DOSBox, Snes9X, or UAE aren't useful?

Second, while I definitely support the push to web technology, I'd still rather have something on Linux or Mac than nothing, and often times Wine is the only realistic way of doing that. I agree it's a little annoying when you buy a "Linux" app, and it's just a wine wrapper, but at the same time, at least it's officially supported and works. I didn't get upset with SEGA when I bought the Sega Genesis collection and it used emulation instead of native ports.

There are a lot more hoarders in this country than anybody will admit.

I do not see how this possibly applies to renters though.
What's interesting about the coupon code thing is if you look at Shopify's checkout page, they include it as an input field along with supporting URL based coupons. I can only guess they've done a massive amount of A / B testing since they have many thousands of stores and millions of transactions.

There's a number of benefits to supporting both IMO:

If someone is talking about your product on a podcast or audio form, being able to say "enter in promo code BENISCOOL at checkout to save 10%" is useful. But then in the show notes, they can link directly to the URL based coupon link. That is much cleaner than having to explain how the show notes link already has the coupon, and you must click that link specifically to get the applied discount. It also works in cases where show notes aren't available (ie. radio -- although that use case is very rare for a digital store).

Another benefit of having it as a text input is during email promotion launches. For example, you might decide to put up your product for sale as part of an initial promo, but then in your email copy say something like "By the way, the next 15 people who use coupon code ABC123 will save an extra $10". You can't really do that with URL-only codes, unless you happened to include a second link in the email (technically could work I suppose, but it loses its appeal and becomes less clear on how it works).

Lastly, another potential use case for input based coupon codes is doing some form of price parity based on geo location. You may want to show people from XYZ country a way to get a discount by entering in a code at checkout, but having it in non-URL form allows you to word it in such a way that it's optional. So if the person happens to live in XYZ country but they are well off enough not to need the discount, they might pay the normal price to show support.

But like you said, the down side is people might hesitate to find a coupon. That's a very hard thing to measure.

Checkout is super interesting to me because I'm currently developing a platform to sell digital items and the check out flow is what I'm currently developing.

I wonder about the actual workability of this scheme. The cities mentioned cover a large area and have things like buildings and airports.

Due to the airports, you can't fly too high without air traffic clearance. You can't fly too low or the buildings are going to block large portions of your view. From a practical point of view, you are going to be limited to flying over specific segments of the city, which leaves your and the city that authorized your flights open to lawsuits claiming that you are profiling residents of that specific neighborhood.

I'm primarily a Mac user rather than a Linux user. Occasionally there is an app I want to use that just doesn't have a macOS version, so I use WINE because then I can run it nearly-seamlessly. A Windows VM can't conveniently access my files, takes up 20GB of disk space, needs regular updating, takes time to boot and shut down, takes up more screen space than the app window itself, requires a license fee, needs its own 2GB of RAM, etc. If and when WINE works, it “just” runs the app for me.

Yeah I'm not all-in on charging 12 year olds as adults, but:

... really?

> How can you understand what 60 years in a cell means when you've only seen 12 under your guardians' care?

Probably seems a lot worse, since a year to a 12 year old feels like at least 5 years to a 30-something. At least this 30-something and former 12-year-old. Summer alone felt about as long as two years do now.

Disclaimer: I don't know Javascript, but that's why:

> ['1','7','11'].map(console.log)
1 0 [ '1', '7', '11' ]
7 1 [ '1', '7', '11' ]
11 2 [ '1', '7', '11' ]
[ undefined, undefined, undefined ]

> parseInt(1,0)
1
> parseInt(7,1)
NaN
> parseInt(11,2)
3

The correct way is:

> ['1','7','11'].map(x => parseInt(x))
[ 1, 7, 11 ]

same as:

> ['1','7','11'].map(x => parseInt(x, 10))
[ 1, 7, 11 ]

The assumption here is that what consumers expect is reasonable, realistic, and sustainable, which ain't necessarily so. If some billionaire gave away chocolate bars for a couple of years then stopped, would we have any sympathy for people who thought that they should still get free chocolate all the time? The ride hailing companies have deliberately underpriced their product.

At some point their chickens will come home to roost. If you take a price that's too low and multiply it by tremendous numbers of units sold, way more than the competition even, you [still end up with not enough money][0].

> You could also imagine why it might be hard for Netflix, Spotify and Prime movies to compete in India

Till a certain extent. Netflix, Prime Videos, Hotstar etc have much more variety and higher quality and some are VERY AFFORDABLE. Prime videos and Hotstar (HBO, Game of thrones, Veep, Silicon Valley like shows) can be had for $14 USD per year EACH. So upwardly mobile Indians can subscribe to multiple OTT streaming services (I do Netflix, Hostart, Primve Video + Apple Music). For the price of one Spotify sub in US, you can subscribe to 5-7 music streaming services in India.

For the rest, Indian creators on YouTube have pretty much surpassed every big name streaming company. TVF, Timeliners etc have created content which resonates with 18-35 year olds on an emotional level. Netflix et al. will never have that emotional connect so easily.
