My experience building a couple of (fairly simple) apps on React Native has been amazingly productive and very pleasant dev experience. I've built a couple of toy apps in Swift directly and can honestly say that I find RN faster and easier. (And I'm neither a mobile dev nor a Javascript expert.)

The hardest part for me was getting React-Navigation and RN-Web to play nicely together so I could have substantially one codebase for 3 platforms. That was admittedly a fair bit of googling and fiddling.

Any guesses on a timeline? Satellite 6.6? Or will it be in the next major version? 7.0?
Not having to know all / as many of the structural details up-front could be of value in some use-cases. It can translate to reducing time-to-start cutting code, which can (in some cases) be a business priority, and can lead to identifying critical dependency problems earlier in development.

I'd happily agree that's an inappropriate model in close to 99% of cases, and that even if it was the right model one could (and most likely should) still use a decent database for this anyway.

When I worked on the main iOS app at Facebook they used multiple solutions in parallel in the app (ComponentKit, AsyncDisplayKit, RN).

So the fact that some projects are using some new server driven technology for some features doesn’t really prove anything.

Unless they specifically announce they are dropping RN support from the app or you see a big drop off in pull request activity I wouldn’t jump to any conclusions.

Can you cite some support for this belief?

When you want to do validation depends on when you can do something about it. I work with a NO-SQL DB at work and while it wouldn't be my choice for most things I would use a DB for, the lack of validation has some benefits. A good example is where you have no ability to validate input from a user, but where you need to store the data anyway. The last thing you want is your noisy data being kicked out by the DB because it doesn't follow a DB constraint. Sometimes you want to go in afterwards and say, "Show me all the data which is incorrect". This is also useful for dealing with important data sent by other systems which have been coded by people other than you. The get the data wrong (or are using older versions of specs, etc) but you want to store what they sent you anyway. Then you can go in later and sort it out by hand.

I don't think that kind of thing is particularly common, but there are definite use cases. In our particular case we use it for financial data where we want the data we are given even if it is flawed. I think the OP is 100% correct. You have to write that validation somewhere or else you are in big trouble. Usually it is easier and more convenient to do it at the DB layer, but sometimes you choose to do it somewhere else.

I can assure you that the distance took its toll on the rovers, in my understanding. Their wheel surfaces eroded, oil pumps failed, bearings degraded and they ended up dragging dead wheels in the end.
Most of the code we are writing now will be garbage in 20 years too. Guaranteed. You do your best with the tools and knowledge you have at the moment. That's all you can do.

I’d say 1 hour of hard labor for every minute of time you wasted, starting at the top of the org, and working its way down (in parallel; no fair dying of old age while the CEO is breaking rocks).

Other than corruption / abuse of government authority, this is the only crime I support the death penalty for.

Seriously.
It's cached at the CDN nodes, which means quick delivery to the device.

This is much better than serving that file from your origin server, and even if you use a CDN it's unlikely that it'll match the hit rates of the public CDNs. That can make a measurable improvement, and at worse is no slower than hosting it yourself.
The general antipathy towards rail seems to be an American cultural thing, mostly. And a relatively recent (2nd half of 20th century?) at that.

What I find especially amusing is when US size is brought up as a counter-point. It had the same size back in the day when it had the most vibrant railway industry in the world.

Yukon is one of the two. But they also made a third a few years ago that didnt exist at the time discussed in the article.
I am not resentful. It's a pretty normal thing when a profession gets more professional and is considered highly paid. It attracts people who aren't naturally attracted to the job. From observation a lot of doctors aren't that enthusiastic about their profession either but do it for the reputation and money.
That is an ambiguity that is fine to write the story about. At least when the headline readers start posting the headline on Reddit others will know that there is an ambiguity to clear up.

I disagree. I'd consume several more hours of new Fyre content if it were available. If they've got more footage and people. Bring it on.
I could be wrong but I believe even at the height of rail, for the most part, it served industry to transport raw materials or finished goods from where they were made or extracted to where they were needed or sold.

First of all, we were talking about validation of data in the database, specifically.

> 'validation' generally implies aspects which are inherently application specific

Not at all. Taking this at face value implies that some app can write data to the database that is valid according to that app, and then another app can read data that is invalid from its perspective, and have to deal with it. That doesn't make sense - data is data, it's either valid, or it's not. That's why the schema is about the data, not about the app.

> Validation in almost every case must be done on the app layer

For UX reasons, mostly, yes. But it's usually much more basic than what e.g. triggers would do in the DB itself.

I'm not saying that there's nothing to validate outside of the DB, either. But for the data that is in the DB, the DB itself can usually do a better job.
How are exceptions handled with this design? For example the `n < 3` may throw (it invokes the valueOf method).
> Always start with in-memory data structure with straightforward persistence (i.e. load and save it all at once, using some popular format).

Do you have any examples of this? It's rare I see suggestions like this.

I've done this for HTML mobile apps a few times before where the entire app (fairly simple) state is saved and loaded as JSON when you make any changes. It's super simple and very little can go wrong. This was as opposed to using Web SQL (which wasn't deprecated at the time) where it's much more complex to keep what's in-memory synchronised with what's in the database.

Edit: I'm talking about client side code to store local state here.

You almost certainly still need to worry about migrations.

MongoDB can store data in a schemaless fashion, however, chances are your application has a data model (schema).

Sure, you can avoid migrations and just tack on more and more backwards compatibility for old data layouts. But performance suffers, and chances are that code quality and correctness suffer too.
Flying is quick, but the time at both ends kills it for shorter trips. I'd rather take the train. I love riding the rails in Europe. It's a very pleasant way to travel.
The article was significantly cut down for brevity, so any detail of how to find the right balance is beyond the scope :)

The original question was that it can be really hard to determine how much adding RAM will offload from the disk. IE: with extstore recent objects are served by RAM and never disk, so they don't count against your IO balance. If you're coming from a RAM backed system that has 500k requests per second, it's going to take some creative introspection to figure out how much RAM you'd need to keep the disk accesses below 400k, or whatever your target is.

Along those lines I just suggested a simple experiment. which is to just take an existing fully specced instance, add a disk, and test a few RAM settings to see how it looks. Most actual users of extstore have just done that since they're extending/replacing an existing cluster.

There're actually other ways you can simply read the numbers out of memcached but it just takes more effort or familiarity with its internals.

I wonder what the rail-laying tech looks like, and if it's made any big advancements in the past 50 years. I would imagine some big advancements in rail construction would tip the scales of cost/benefit.

Let's invest in self-replicating rail construction!
Even with parking for a couple days priced in, it's still considerably cheaper to rent a car and drive from DC to NYC than to take the train (and takes about the same amount of time). I much prefer train travel but unless it's heavily subsidized the way highway travel is, I don't think it will ever be competitive or widely popular.
How is this? According to the International System of Units, a minute is 60 seconds.
But they seem to prefer slow driving over the idea of trains, for shorter distances?

Late post but I didn't dismiss the OP as an idiot, I'm saying they are ignorant of how things work and extrapolating the state of technology based on visible end results is not accurate in anyway.

As for the rest, I've described this in the previous 2 posts. Precise targeting is possible. Every ad network has their own special focus, and yes many are useless or have been obsolete thanks to an evolving market. Not all of it is about a single visitor identity either. However just because targeting is available does not mean it's always used or always worth the price.

If you're selling toothbrushes, you don't need precise data. If you're selling million-dollar industrial equipment then it's worth paying the money to target the right people in their office. There are 1000s of factors that determine what you see and many are purely business and supply chain related with nothing to do with relevance so more often than not you'll see an ad that only has rough generic/contextual targeting and think the algorithm sucks when in reality nothing was applied in the first place.
React Native isn't even 1.0 yet. They are working on lessening the need for native development.
Another comment explained this. They set a goal of 90 days to get the data they needed. When they presented the proposal for budgetary approval, 90 days of data collection was considered worthwhile enough to greenlight the project. So they accomplished it. However once you already have a working rover on the surface you might as well operate it as long as it lasts because the marginal costs are minimal compared to the initial costs. So they kept requesting additional funding to keep the program running.

I see nothing wrong with this.

high speed rail is a beautiful thing.

who’s gonna be the guy who eminent domains all the existing developed property to unkink the existing lines so they can support fast trains?
Japan also has a privatized and almost fully-tolled highway network. A high-speed rail ticket for me to Fukuoka costs 9,000 yen; to drive a car instead the tolls alone cost 6,200 yen, add gas to that and the longer time it takes to drive, unless you're loading your family into the car the high cost of driving makes taking the train highly attractive. The US would never tolerate highway tolls like Japan has.
The US has a great freight rail network that is highly used.

The US still has one of the most vibrant freight rail networks in the world.
Nonono, disabled people might be barred from using a service because of excessive recaptcha. That's what he means. I also think he really meant CVAA rather than ADA though.
I recently replaced a bunch of securimage captchas with reCAPTCHA v2. During testing I had to shut it off because it became increasingly more complicated every page reload. First it was just one page of traffic lights, but 20 minutes later I was having to click through 5-6 pages of images. This worries me that user's might get pissed off. I'd really like to know if I've made life harder for my users in an attempt to stop the spam from the horribly broken securimage captcha.
>Those wide, droopy sleeves you sometimes see in historical shows? Rich people simply bought clothes that used more fabric, just so they could show they could afford it.

As far as I know it was to demonstrate that the owner of such clothes doesn't have to work. Because such clothes make it extremely difficult to perform any manual work.

Related and no doubt even as infuriating is the tendency to also decrease the contrast of UI elements by, in addition to adding copious amounts of whitespace, turning blacks into light greys. I remember one instance where an internal website was "modernised" with a new stylesheet and panicking for several minutes wondering if something was wrong with my eyes or monitor, because everything looked faded and unclear in addition to the nauseating effect of the sea of whitespace. My coworkers were just as repulsed by the change, and after confirming with the department responsible that they were not going to revert the change ("because we don't want to go back to old stuff" --- that's literally the explanation I was given), took several minutes to come up with a user stylesheet and distribute it to everyone else interested.

To this day I am still astounded that more than one person thought #BFBFBF is a perfect colour for text on a white background.

America actually does have a world-leading rail system...for freight. In fact passenger trains usually travel on freight tracks (yes, even Caltrain from SF to SJ) and have to give way to freight which is prioritized.

As far as HSR goes, the article is actually unfair when it talks about the Line running through the Central Valley. It's a lot cheaper to run the line there than any straight line between SF and LA. More importantly, tying Bakersfield, Merced and Fresno into the Bay Area and LA regional economies would be great for all three.

I was suprised to learn (from the wiki page) that the kelvin, mole, and ampere do not have exact numerical definitions yet, though I guess that's expected to change in May of this year.

And then there's the candela, still basically defined by how luminous whale blubber is when it is burning:

> Current (1979): The luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 5.4×1014 hertz and that has a radiant intensity in that direction of
1
/
683
watt per steradian.

> Note: both old and new definitions are approximately the luminous intensity of a whale blubber candle burning modestly bright, in the late 19th century called a "candlepower" or a "candle".
How so? I can drive to NYC from Boston, that's a little slower then the acela, but then I am not bound to the train schedule. It's more convenient to me.

I'd like to see high speed trains, but it's never going to happen in the US without massive investments. Too many special interests.

The author seems to have completely missed the lesson that designers should get buy in from the people who actually use the tool, or at the very least should be required to use their own design under realistic conditions. If you just want to apply design principles and not worry about whether your work is accessible, stick to fine art. I feel no sympathy for the designer in this scenario, s/he deserved to fail.
"Measure theory a la Bourbaki" is probably not what you meant if you did probability theory and statistics. Bourbaki famously sidestepped classical measure theory with sigma algebras by constructing Radon measures as functionals via functional analysis. This is sufficient for many purposes but not for probability theory. First and foremost, sigma algebras in probability theory are not just a technical device to avoid paradoxes with unmeasurable sets. Sigma algebras play a starring role in conditional expectation, stochastic processes and martingale theory.

The best way to appreciate the information-theoretic role of sigma algebras is to look at them in the simplest case, where you have a discrete-time, finite-valued process. Then a sigma algebra is equivalent to a partition of the state space and it represents the information that can be gained from an observation; it's like a random variable without specific values, just the discriminating information from different outcomes. To say that a random variable is measurable with respect to the sigma algebra is to say that its value may only depend on information that can be gained from an observation. A filtration of sigma algebras corresponds to a causal series of observations where the observer learns more information over time.

The conditional expectation of a random variable with respect to a sigma algebra (or partition or other random variable) is another random variable that tells you the expectation over the states consistent with a given observation; this new random variable is measurable with respect to the sigma algebra you conditioned on, which as mentioned earlier means it only depends on the information gained from an observation. The conditional expectation is the best least-squares estimator given the information from an observation in the same way that the usual expectation is the best least-squares estimator given no information.
CO2-capturing artificial leaves ready to leave the lab
I would not suggest people try to waste scammers time, or do anything but hang up on them. A lot of calls that just hang up on you are putting out the feelers for phone numbers that have humans answering on the other line so that they know that's a viable target for attempting to scam. Showing any sign that your phone number belongs to an actual human just ups the chances that you're going to get an increased amount of phone spam, regardless of if you got the chance to waste someone's time or not. Also, people should be wary of saying anything at all the these suspicious phone calls, some of them try to get recordings of you saying some key words to make it easier to steal your identity. For instance, if someone asks if you are who you are by name and you say yes, then they've got decent confirmation that they've got a recording of a particular person saying "yes" which can be used against you in stealing your identity or credit card fraud.
As a data point, Tesla isn't very good at delivering body parts to independent body shops. I don't see why dealers would be any more successful at nagging them.

I also suspect it's a lot easier for Tesla to fix their parts problem than it is for dealers to stop being smarmy.
