Feels like the marketing went overboard there and comes across as more trying to attract 'suckers', rather than actually having a good product.

Little known fact: one of the first self driving cars was a 'Humvee' (real name HMMWV) which was equipped by DARPA with cameras and could navigate a road with no other vehicles, and go straight through a 4 way intersection after stopping (again, no other vehicles). This was in the mid 1990s. Would love a link to this project if anyone has it.

It's a skill you get better at. Correctly guessing most of the time, looking a little ahead when you can, that kind of thing. Like sight reading music, really. Combination of well-trained intuition that mostly gets things right and sneaking a peak at the next few notes or bars when you have the opportunity. Definitely works some different mental muscles than silent reading.

Have to skip the too-sexy or ultra-violent (or, uh, both) bits, but it's working alright.

I don't think this move was caused my Amazon buying Whole Foods. It's not like Whole Foods and Target are really in competition at all.

Seems like this was long time coming. I'm sure Amazon's been cannibalizing Target's business in the electronics/books department already. Come to think of it, the only thing I really go to Target for is clothes (I like some of their brands) and Amazon's starting to invade that sector too with Amazon Fashion.

I've seen the best success in the NoSQL world when you treat data like a history book rather than a moment in time.

What I mean by this is creating entities, mutating them, and trying to maintain a state is the natural pattern to assume, but it is often wrong. It leads to a many issues reported here and elsewhere and people declaring "such and such DB sucks". This is a SQL approach to using data and NoSQL fails badly at this generally speaking and should not be used to store "state" since state often requires ACID and relationships.

Treating data as a history book, or log of events over time is a safer way to use NoSQL as an authoritative source. It plays well with their ability to scale simply and naturally and event data has no relations. Everything in the single event is immutable as it is a fact of occurrence. Invalidating a past event is as simple as generating a later event that says that event is now invalid from this point in time.

From this you can generate "entities" which describe a relationship between your events. From your log data you can generate a session, for instance. These are not authoritative sources and if found to be invalid you recalculate the entity, or state, from the collection of events.

I could create an entire social network profile for a person by aggregating and querying the history of events that make up their current state. And the real power is I can generate their state at precisely any point in time in the past and possibly predict what their state will be in the future based on their past stream of events and derivative states. If a past event was found to be invalid, a new event declares this and with a greater timestamp authorizes that fact and I can recalculate the entity that describes their "current state".

This takes work and thought though and one of the promises you've seen from some NoSQL vendors is they save you work. The work is always there but you need to get comfortable thinking of data in a different way and not all data needs this approach. But, in many cases, NoSQL is not trash.

So I can't speak to what you think is and isn't possible. But maybe take a look around you, find your local heroes, lend a hand.

Shooting is using deadly force. Shooting a suspect to intentionally avoid fatal wounds is a TV myth (most episodes of Quinn Martin's "The FBI" ended in this way, for example).

Every LEO in the country is taught to shoot only when deadly force is necessary and to shoot for the center of mass (and continue shooting until the suspect is down).

Shooting with intent only to inflict an immobilizing but not-life-threatening wound is inherently wrong and has been held actionable by the courts. If the LEO had the luxury and time to even consider such a tactic, then aim and fire, then by definition no innocent life was in imminent danger, and therefore the use of deadly force was excessive.

And if you take another look at your source, you'll see that there is no stated intent to only wound the suspect in that German case.

A good study of such situations is the Massad Ayoob book In the Gravest Extreme.

The extra bits mean you can change how you filter the sound later, depending on what range your headphones/speakers are capable of reproducing without distortion, or what your ears are capable of hearing.

Who knows, maybe technology or genetic changes will allow future humans to hear in a wider range than we do now. Those people might appreciate being able to hear what our music really sounded like.

Yes. The realistic alternative to pivoting isn't beating yourself up in a press conference or something like that: it's self-sabotage. People self-sabotage so they can pretend they never tried and thus avoid seeing themselves as failures.

How do you count "floods"? If there is one hurricane that causes floods in 3 cities, is that 1 flood, or 3?

If it's 1 - which is what I think is meant when saying "a 1 in XXX years flood" - then your comparison doesn't hold, because the number of floods isn't dependent on the number of cities, but on the distribution of cities on the land, and specifically in flood-prone areas.

What databases are similar to MongoDB either architecturally, storage engine or data model?
I think it's an interesting question.

One use case example: if I'm looking up resources to learn about cryptocurrencies, I want a web 2.0 style experience. If I'm on an exchange and trading those cryptos, I'd rather have a real-time single-page experience (I think poloniex does a decent job as an example). Even single page apps seem to have a lot of additional 'web 2.0 style' pages supporting them, so the entire thing can become blurred. Even with 'single page apps' you'll often have separate interfaces for user admin, splash pages, etc.

multi-page sites seem superior if you're more concerned with things like search engine traffic, maximum compatibility, smallest size, lowest maintenance, interacting with standard browser functionality (i.e. letting users bookmark pages in your app, browser extensions, etc).

Single page seems better if you're more interested in feeling like a desktop app, more interested in UI/UX, serving notifications, showing live feeds, letting the user 'sit back' while you deliver content.

Californians: Here’s why your housing costs are so high
For distortion and compression, the only possible difference I can think of is aliasing, and yeah you could just oversample your input, then downsample again on the way out. This is really really common in most professional plugins, often with an adjustable amount to balance quality and CPU usage.

I also have some gear that aliases at a volume you can't hear, but when you plug it into an analog distortion pedal, the aliasing in the high frequencies becomes apparent. This would be avoided if it had a higher sample rate so the aliasing was far out of the audible range.

For other sorts of effects like spectral processing, pitch shifting, the extra detail above 22khz really does make a difference, especially if pitching down.
In 2 Texas cities, sure, but in every U.S. city? There are going to be several that end up getting a few 500-year floods... and several others that don't flood as expected in several 1000 years.

> Not at all, bitrate differences are audible.

Even with the same bitrate, you’ll need 4K video to get quality comparable to uncompressed 1080p.

For example, mp4 defines that the brightness channel Y should be stored with full resolution, and the color channels Pb Pr should be stored at half resolution. So in a 4K mp4 video at lossless bitrate, the actual colors will only be stored at 1080p. This functionality is called Chroma Subsampling.

Audio Codecs do something very similar, causing these exact issues.
It doesn't seem to say anything like that. Looking at it again, I see this:

> It is also worth mentioning that increasing the bit depth of the audio representation from 16 to 24 bits does not increase the perceptible resolution or 'fineness' of the audio. It only increases the dynamic range, the range between the softest possible and the loudest possible sound, by lowering the noise floor. However, a 16-bit noise floor is already below what we can hear.

But I don't understand, why is this? Is the step in volume between two values fixed regardless of the bit depth? If so, why?
> google has a monopoly on search so this is a reasonable assumption.

Yes, lower latency is a pretty good example.

Also people tend to drain marshes and any other shallow stagnant waterways to avoid mosquitoes having breeding places. It can save us from terrible diseases, but it can make flooding worse.
Writing the code is probably the easiest part of all this. Testing and design are going to be huge.
With video it’s not about bitrate, but Chroma Subsampling.

Basically, mp4 and webm video only encodes the brightness channel Y at full resolution, and the color channels Pb Pr at half resolution. You can’t have mp4 or webm video without Chroma Subsampling, it’s defined in the codecs standard.

Audio codecs do something very similar, cutting off a large percentage of the higher and lower frequencies. mp3 (and AAC) for example allocate almost the entire space for the frequencies around 4 to 8kHz, and drops then drops a certain percentage of the upper frequencies entirely.

The article talks about uncompressed audio, but the topic he responds to is Apple choosing to sell 24bit/192kHz AAC lossy compressed audio. The author of the article is responding to a business decision, which has nothing to do with the actual topic of the article.

Interesting. Seems like that would just be one part of a larger application, though. And for that, my mind just jumps to something like Postgres with `jsonb` fields to store it all denormalized, then using columns to store relations, like the contact it was sent to. Along with other tables for other parts of the application, of course.

A bloodless war is unable to inflict the necessary pain to force people to change their minds. The actual military logic goes like this...

If the source of a country's military might is the ability of the civilian population to produce goods needed for the war effort, then the civilian population becomes a legitimate target.

The result of that logic in WW II was mass bombing campaigns which were capable of "dehousing" 100k+ people in a single night.

But a student trying to develop for Android can’t afford devices that start (!) at 908.35 USD. (Price of the Pixel 5" with 32GB storage, in Germany, right now).

Suppose you have a 5 Mbps data budget, 1080p display, and 4k source material. You will get better quality by first downsampling the 4k to 1080p and then compressing and distributing the result. If you compress and distribute the 4k, followed by downsampling to display at 1080p, you cannot recover the color and/or motion information that was lost in order to fit all of those pixels into 5 Mbps.

However, if you have a 20 Mbps budget for the 4k to account for having 4 times as much original data, then there shouldn't be much of a difference in the downsampled 1080p video (ignoring peculiarities of the codec).

All this is not very relevant to the audio issue being discussed. It would be relevant if it were physically impossible to perceive the difference between 1080p and 4k video, and if watching 4k video potentially caused optical illusions. In that case, the only reason to prefer the 20 Mbps 4k stream would be if you planned to edit, mix, or zoom around in the video instead of simply watching it.

When it comes to audio, since size isn't as much of a concern as video, in most cases I would say "maybe I'll want to edit it someday" is strong enough reason to get the 24/192 material at a correspondingly high bitrate if it's available.

> If jury duty is random why not political duty?

Jurors are asked to do a couple fairly common tasks that most people do frequently throughout their lives: (1) listen to different sides of a story and decide which side to believe, and (2) decide the motives for a person's acts.

A legislator is asked to judge complex policy questions often requiring extensive specialized knowledge. The arguments for and against are often long and complex. It's not a job you can expect to take some random adult off the street for and have them do it competently.
Well, its certainly a common belief that the requirement to pay taxes in the national currency gives a national currency its value, but the hyperinflationary events in Zimbabwe and the Weimar Republic (and the subsequent worthlessness of those national currencies) demonstrate that this requirement is insufficient to give currencies their value.

In fact, the only thing that gives currencies their value is people's belief that they have value (much like gold before national currencies).

I'd also like to add that "countries" dont have goals, countries are made up of people, and only people have goals -- and all people are self-interested. The people in control of monetary policy are just as self-interested as the miners are, instead of receiving profit directly like the miners they inflate currencies to the benefit of major banks in their countries (and subsequently get highly paid jobs at those banks or elsewhere in the finance industry).
The issue I have is with the dietary trend of pairing foods in order to obtain a "complete protein," which is extremely silly. Dying because one of the amino acids is not represented in your diet is something that basically never happens to a well fed person (it would take an extreme example, and the internet can supply those, but...) so I have no issue with it one way or the other in a discussion about diet.
