Thanks, that makes sense. So, by describing a fluid as a surface instead of a volume you'll need less calculations to simulate the fluid and you'll gain performance.

Let's dive into the details of the abstract. Please correct where wrong!

'... for simulating incompressible, inviscid and uniform-density liquids with surface tension in three dimensions.'

So it only works when you can't compress the fluid, the fluid is not sticky like honey or oil, had as uniform-density, and is an enclosed body (bubbles, not seas).

'The liquid surface is captured by a triangle mesh on which a Lagrangian velocity field is stored.'

There seems to be two ways of looking at fluid motion. The Lagrangian way is following an individual parcel through time and space. The Eulerian way is looking at a specific location and watch fluid flow through that location.

'Because advection of the velocity field may violate the incompressibility condition,'

Advection is the transport of a property by the fluid due to the fluids bulk motion. So the speed of fluid might compress the fluid, and that should be prevented.

'... we devise an orthogonal projection technique to remove the divergence while requiring the evaluation of only two boundary integrals.'

Orthogonal projection is representing a 3D object in two dimensions.
In two dimensions there can be no divergence if I understand it correctly.

'The forces of surface tension, gravity, and solid contact are all treated by a boundary element solve, allowing us to perform detailed simulations of a wide range of liquid phenomena, including waterbells, droplet and jet collisions, fluid chains, and crown splashes.'

The mathematics of surface tension, gravity and solid contact are much easier in two dimensions than in three. The boundary element solve is an efficient method to solve equations with boundery integrals. So liquid behavior can be modelled in more detail and visualized in a realistic way.

Now this is really interesting. I've been asking myself why this hadn't happened before. Its been all software, software, software for the last decade or so. But now I get it. We are at a point in time where it makes sense to adjust the hardware to the software. Funny how things work. It used to be the other way around.
I've had very much the opposite experience with Fitbit, twice.

1. I had an old FitBit Ultra that stopped syncing to the base station. They sent me a replacement base station but that didn't work, but I forgot to follow it up. Fast forward a year and I find my (now out of warranty) Fitbit in the back of my Man Drawer. I dropped them an email on the off chance that they'd take a look at it for me and instead they sent me a free Fitbit One.

2. My wife dropped her Fitbit One on the school run and didn't notice until later in the day. On the way back to pick up our daughter she found her Fitbit by the side of the road with half of the electronics hanging out due to having been under more than a few car tyres. I suggested contacting Fitbit to see if it could be repaired or if they offered refurbished units, and again they sent her a brand new Fitbit One completely free of charge.

I'm sure the level of customer support varies geographically, but since the above I've had nothing but good things to say about Fitbit UK's customer support.

They do. And the balance of probabilities is that the urinalysis is more likely than not to be accurate (I don't know percentages). So as a mandated reporter, they did what they could.

They gave multiple chances for retests. The results were consistent.

A blood test four weeks prior to delivery would be a good start, but still leaves a window.

There are two suboptimal possibilities at that point:

1) err on the side of the mother, who has failed (incorrectly as it may be) multiple drug tests and allow her to breastfeed her child, or

2) err on the side of the child, who is exhibiting symptoms that could point to NAS, bradycardia and the like, who is delivered by emergency C-section (so she would not have had the bonding experience immediately post partum, as it was, anyway)

They did know the failure mode.

They evaluated.

They held off on calling CPS. They allowed contact after the baby's urinalysis.

There is no negligence here. The father showing by their own words anecdotal forum posts and such is not reason for the hospital to say "Well, what do we know, here you go".
I wonder if there is some room for an ultra cheap "micro" PAAS, like 2$/month per instance, with 250 Mb space and 128 Mb RAM or something like that.

Get a €2.99/mo Scaleway VPS (2GB memory, 50GB SSD), install Dokku - http://dokku.viewdocs.io/dokku/ - and you basically have a Heroku-like environment for next to nothing (especially as you can host a bunch of apps on that single instance).

(Update: Didn't know Scaleway was still queued up for signups. Replace with DigitalOcean for $5 if you're in a rush - and host fewer apps per box ;-))

You are making a mighty fine distinction, one that sometimes makes no difference. You are also assuming that "access to attention" is perfectly firewalled from data, which it isn't. I know one person who is playing with what correlations can be made by getting people to click on google ads. I can't imagine he's the first.

You are also assuming that Google's policy will never change, Google's assets will never end up for sale, etc.[1]

Obviously, we weight these things differently. But calling it nonsense demonstrates either contempt for those you disagree with or a lack of thought on the matter.

A baby's heartrate (as measured by either an external transducer, or a probe hooked into the baby's scalp) is an objective measurement. Comparing it to the completely subjective "signaling" of a police dog is absolutely absurd.

Much of the 'prepping' requires the mother to be present (administration of anesthesia, monitoring, etc). The prep of the OR is generally done in parallel with those tasks. If it takes you 30 minutes to the to the hospital, you are delaying a c-section by at least 30 minutes.

Additionally, measure that can be taken to reduce fetal stress (while waiting for the OR to be prepped, in the event that is delayed) are _much_ easier to accomplish in a hospital, rather than in a car, or the back of an ambulance.
There may be some good reasons for this, but for even the best companies, it's shady. And comcast is far from one the best companies.

Instead, they should create a site that is clearly comcast branded and shows the results of each step.

Unrelated stuff going on in the birthing center?

I am describing a situation where the midwife/ doula was MORE CONCERNED with maintaining a "positive and serene energy in the birthing space" (her words) than she was about what we would do to take care of a critically ill neonate.

I can assure you, my methodology on such a call is not to "stay and play" but to "stabilize, ideally while transporting". Let alone a fishing trip. To wit, I could not care less what else is going on in the home, be it legal or illegal, unless it directly affects the care I am or need to provide. My reference to DOH was not a "fishing trip", but in regards to a provider who, in my professional opinion, was being actively negligent in caring for what was their patient, until transferred to me.

I think your biases are showing.

550 hours a month for ALL dynos is too limiting. Oh, and Firebase just got updated today. Guess what, I'm about to switch to Firebase.
I'm not sure, I was on the waiting list for a while, I've been in the beta for about two weeks now.
The concern I've always had with Firebase is the lack of a business logic layer between clients and the database. This tends to force the business logic into the clients themselves.

Trying to change the schema if you have Firebase clients deployed that can't be instantly upgraded via a browser refresh (i.e. iOS and Android mobile apps) seems an extremely challenging task.
Yeah, the first day is a huge hype show.

All the journalists buzz around, and all the product managers/execs/reps are there to show off for them.

For example, when I went, the wi-fi was horrible, basically unusable - except if you were in media. If you were media, then you got your own area to connect to better internet.

That said, the subsequent days were noticeably quiet in comparison.

Not too many people there to actually go to dev talks, etc. It's very relaxed by then.
I'm guessing that the performance / watt claims are heavily predicated on relatively low throughput, kind of similar to ARM vs Intel CPUs - particularly because they're only powering it & supplying bandwidth via what looks like a 1X PCIE slot.

IOW, taking their claims at face value, a Nvidia card or Xeon Phi would be expected to smoke one of these, although you might be able to run N of these in the same power envelope.

But those bandwidth & throughput / card limitations would make certain classes of algorithms not really worthwhile to run on these.

> rendering previous drills potentially obsolete

This is the flaw in your reasoning. A better drill does not make the older one incapable of doing the same thing it has always done to meet your needs. For something to be made obsolete, the alternative must be definitively superior by definition, so the reason for picking the superior option is clear in such cases, but even then, you don't have to use the superior tool. If a traditional drill can meet your needs, you are the one creating a problem by using a tool that doesn't provide you with clear benefits.

> My brother-in-law is a builder and I would certainly ask him what drill to buy if I needed a new drill, and I'm sure he'd have an answer.

If you told your brother-in-law you needed a new drill, he'd likely ask "what are you going to be using it for", and then you'd explain your requirements and he'd give you an answer based on that. If you said "I really want to get into building stuff, but I'm not sure which magnetic drill press is the best option for a beginner", he'd probably say "whoa whoa whoa, that's a specialized tool for a specific kind of job, just stick with a regular drill and if that doesn't do what you need come back and ask me again".

> Can anyone in web development really answer definitively as to whether you should use npm by itself, grunt, gulp, or even make?

The crux of my point is that this isn't a useful question to ask. The question should be more along the lines of

Q. "I need a way to run some custodial tasks related to the operation of my application, what should I use to accomplish this?"

A. "Well, you could write some shell scripts and run those directly or with npm's script running capabilities, or if you prefer to use JavaScript to define these tasks since you're already using that for your application you can try gulp or grunt; grunt takes a more declarative 'config file' approach while gulp takes a more imperative 'streams' approach but they basically do the same thing, though, you've been a C programmer for 10 years so you might already feel comfortable with make, so you could use that I suppose, but you won't be able to easily import js code from your application into make so if that's something you want to do then you probably want gulp or grunt...." etc.

These tools didn't just emerge from the ether, they were created in response to specific issues. The existence of some arbitrary library or framework has absolutely zero impact on whether or not your existing solutions are adequate for the problem at hand.

A desktop PC is more than able to do good speech recognition as long as it's able to train the model for individual voices. Getting good results without training the model for the user beforehand is harder, and you would probably never be quite as good as a cloud-based system.

A Pi, though, couldn't do well at all, just like you said. If I wanted to build a system like this for myself, I would target an HTPC form factor.

edit: Another possibility, which was explored elsewhere in this thread, would be to keep the listening device "thin", but have the ability to offload the processing to a machine in my LAN instead of one the "cloud".

You realize paramedics are qualified in neonatal resuscitation, right? While "scoop and run" is absolutely the right thing to do in some cases, if I'm handed a blue baby, I'm going to spend some time in stable, well lit environment getting an airway established. The sooner that happens, the better the baby's outcome is going to be (and it's much harder to do bouncing down the road in the back of an ambulance).

You know what I would want my phone to be doing? To be actually always listening. So that I could just say "Ok Google" at random and interact with Google Now without having to unlock the phone or have it constantly hooked up to a charger.

(I mean, what the hell - deep in the options of Google Now I can actually allow the phone to be unlocked by my voice - but if and only if it is plugged to a charger. They had to explicitly code in a special condition to make Google Now less useful.)
