Dart2 is optionally typed in that you don't have to enter the types. It's different from original Dart in that previously, if you didn't enter the type Dart would assume you meant "dynamic", whereas Dart2 will infer the type based on what you are actually doing. The net result is that the compiler/analyzer will catch more bugs but the code looks more or less the same.

> What you do or do not do should not be grounded in the consequences that you will face but in what's the best for your users.

I agree with the above. I disagree however that "what's best for your users" is universally a superset of GDPR regulations.

My personal view is that if your company/service becomes so powerful that people can't escape from its influence, the above regulations are a necessary evil in order to counter your outsized influence.

For a tiny startup on the other hand, you have so little influence on the world that if a consumer doesn't like the way you operate, they can just choose not to interact with you. Such startups can best serve both themselves and society at large, by focusing on building valuable features/services.

Reasonable people can disagree about the specifics of a law. As a EU citizen, I can understand your wishes for everyone to comply with EU regulations. It helps to put yourself in others' shoes, and ask yourself how much time/energy you, as a startup founder, would be willing to put into regulatory compliance with Canadian/Russian/Indian laws.

You can simulate CPU throttle in Chrome, in dev tools under the performance tab. I'm not sure how effective it would be to your use case, though.
Not sure why you're being downvoted. XAML definitely supports complex widget composition in markup. Since the XML is basically just describing an object graph, it's a more concise way of writing the equivalent imperative code:

<Button>
<StackPanel>
<Image/>
<TextBlock/>

...

<Button>
<Canvas>
<Ellipse/>

although the Dart syntax makes this look similar, albeit a little more verbose, if you squint.

Full disclosure: I work at Microsoft.
Some of these packages look absolutely beautiful. Being a hardware noob that has only worked with Arduino and Raspberry Pi, I'm used to having to buy all these overpriced accessories to fit into their boards. These mini mobos with integrated cooling fans and all the bells and whistles, look really awesome. Does anyone know how big the mini mobos actually are?

Reading it again, I guess I missed the "shadow memory" concept they talked about, but they only mention it 5 times and none of those mentions are in the actually explanation of how they do the memory tagging. They do mention it one more time in the AArch64 implementation though, so it does look like you're correct on this. I don't understand why they didn't really make this detail much more clear though, since like you've pointed out it changes a lot about how things work.

Now, if that is the case it complicates the setup a fair amount, since now you do need a global 'page-table' like structure holding this information that the allocator configures. And from reading the paper, don't they intended for the kernel to do this checking as well on userspace pointers, indicating the kernel also needs access to this information? It's doable, and better overall, but more complicated.

Don't offer shipping options to the EU.

If dealing with digital products, allow people to purchase without creating an account, or require them to select a country as part of account creation (and prevent those selecting the EU, or don't make it an option). If the bank processes the payment, but you've collected no information, you can't run afoul of the law (since you have no information).

I wouldn't be so quick to write them off. A large percentage of the world respects the Chinese government which usually acts in their own economic interest is stable over the long term. Whereas in the US the government does nothing but enact poor economic and social policies as well as saber rattling or war every time a right wing president is elected.
So I took a good look at the docs and as a React Native developer, I do have some questions:

- Is there code linting support in Visual Studio Code? I find that having a style guide, even if loosely enforced, helps a lot in learning how to structure code for long term maintainability.

- The state of packages, in particular those that expose native SDKs, looks just like the early stages of native modules on RN. I know this is a beta, but what is the time frame for when all of these SDKs to mature? Or is this all on the community, in which case, I wouldn't be very convinced to use Flutter considering how long it took for good native modules to stabilize on React Native.

- Why aren't the licensing requirement bits mentioned on the actual doc pages for Drawer and Material Components in Flutter? It's in the FAQ, but if they are required, putting them in the docs would be better: https://flutter.io/faq/#how-can-i-determine-the-licenses-my-...

- Is there a roadmap that is more detailed than the milestones (https://github.com/flutter/flutter/milestones)? With React Native, I know that support isn't going to suddenly dry up because it's an integral part of Facebook's current tech stack. So even if they don't focus on what I prioritize, at least I know it's being improved. With Google and their support reputation, I'm much more concerned about spending time to pick up Flutter & Dart only to have support taper off.

Advice for Introverts: How to Thrive in the Business World
For interested parties, here's the most recent paper on anisotropy, ie how we know the particles are extragalactic: https://arxiv.org/abs/1709.07321

I also worked in this field (Pierre Auger Observatory in the Karlsruhe group) before I "sold out" to join a tech company in late 2010. Might we have met?

Back to cosmic ray anisotropy. There was actually a big paper from the Pierre Auger collaboration in 2007 on anisotropy that made it to the cover of Science. It correlated arrival directions with a I catalog of, IIRC, AGNs. I was in my first year in the group so I didn't make the author list yet. I was quite disappointed at the time. Pretty much from the moment of publication, however, the statistical significance we got from the data started decreasing until it was no longer something we were particularly confident in. The collaboration had to publish a note on that. Ouch. We never worked out why this was happening (if other than horrible luck) before I left.

Before the publication there had been interesting internal discussions about whether to publish. The astronomers typically felt the significance was plenty by astronomy standards and we were trying to do astronomy with particles after all! The particle physicists tended to want to apply the more conservative thresholds that are common in accelerator physics. After all, what was our detector if not a giant calorimeter? :)
Silicon Valley's political influence might be a large splash but finance is the pond itself.

> $X.99 pricing is not generally used in B2B or prosumer (professional consumers) services because it communicates cheapness; I’d suggest you drop the 0.99 accordingly here, for aesthetic reasons. (No series of A/B tests I’ve ever done generated as many strong opinions as whether it was better to price a product at $49, $49.99, or $50. Despite bikeshedding this to death at several clients, I’ve yet to see it really matter, so aesthetics win the day. If your data says differently, trust the data.)

Interesting, I would have said $X.87 is still the best strategy when talking pricing/extracting value, even for B2B.
If by "alphanumeric" you mean [0-9a-zA-Z], that's an alphabet of 2 * 26+10=62 characters. Since I'll be doing this in my head, I'll add two punctation characters so we end up at 64=2^6.

Now, I assume you mean "five character prefix of the hex-encoded 160 bit hash"? One hex digit is half a byte; a nibble or 4 bits. 5 * 4=20 bits, leaves 160-20=140 bit hash. Which can represent 2^140 different values.

För a password of 1 to 16 characters from our alphabet, we have 64^16 passwords. The five character prefixes account for 64^5 of those.

64^16=2^(6 * 16)=2^96

64^5=2^30.

(2^96-2^30) < 2^140.

So, if I understood your question: all of them could (should) have unique representations in the remaining hash.

But I think you meant how many would collide in the prefix?

That'd be (2^96-2^30)/(2^20).

I think, it's getting to be bed time. But at least I should be sufficiently wrong for someone to correct me ;)
How does the fact that banks hold a fraction of their assets in a central bank put pressure on companies to grow exponentially? I'm curious, I don't understand the connection.
There's something I don't understand about that type of explanation.

Say a particle and I are moving along like so:

-----[photon @ speed of light]-->
-----[me @ 50% speed of light]-->

Or more simplified, say two cars are moving like so:

-----[other car]-->
-----[my car]-->

When I'm stationary, I see him go past at 100km/h. When I move at 50km/h, in the real world he would now appear to only be going 50km/h. But if I slow down my time to half speed, now he'll look like he's going 100km/h again. Because he looks to me like he's at 50km/h at double time speed = 100km/h. That seems to make sense - time slows down and the apparent speed stays at C (100km/h in this case).

That's how I've understood the explanation for relativity. But it must be a very wrong understanding - because that whole idea breaks down when the other car is going along a different vector to me! In this situation:

<----[other car @ 100km/h]--
-----[my car @ 50km/h]-->

His speed relative to me would come out as 150km/h in the real world, and no amount of making him look like he's going faster would reduce his speed to 100km/h.
Nice site, one suggestion you may want to allow users to search for something in their domain expertise so they can trust it more rather than the canned examples. Just a thought.
FWIW what we've seen in usability studies is that people who know JavaScript can pick up Dart without even noticing. (Literally, after an hour in a usability study we'd ask people what language they'd been using and they would respond with surprise, having not even noticed that it was a new language.)

Regarding trusting us to support a new framework, Flutter is entirely open source, so if Google every gives up, the code is still out there and can be maintained. Having said that, since AdWords is starting to use Flutter, it's probably going to be supported for a while.

I believe we have a sample app called "Flutter Gallery" in the app stores. See https://play.google.com/store/apps/details?id=io.flutter.gal...

One thing about racial diversity - a lot of metrics simply divide up the world into 4 groups (white, black, asian, hispanic) and then measure how close a population is to 25% of each group.

Quite a while ago (like 15+ years ago), I read a bit on language diversity, a chart of the number of languages spoken by at least 1000 households. San Francisco actually was highest on the list, higher even than New York (which was also very high up there).

Sorry for no cite, it was a while ago, I haven't been able to recreate this. SF's diversity may have dropped a bit since then, but it's most assuredly still there (I hear several different languages at least every day just walking around). But I do think it's another decent metric. After all, by the first measurement, there is essentially no diversity in Asia, which is absurd.

They probably won't reach 5,000 a week until in the second half of the year. They're at 1,000 a week right now.

Still, at least the car seems great. Being a year behind in production is not going to matter that much in the long-term, even if say 50,000 people cancel their orders. They'll probably keep the pipeline full for the next 3-4 years, while still steadily increasing production. I'm sure larger carmakers have had such delays for at least some of their car models, too.
Well, that's bound to happen when framing questions on the same topic.
What happened when Mao unilaterally declared that ploughshares should be melted down for the good of the economy?

I'm not a huge fan of authoritarian systems, but individual people are even more fallible. Laying decision-making power on one individual is a recipe for failure; they're going to be wrong eventually, and chances are people will be reluctant to speak out against their god-emperor when that happens in a system where power is so ridiculously centralized.
We're a small team, so we have to start somewhere. Mobile is where there's a real lack of good solutions right now, so that's where we started. If we're successful and our team grows, or if we get contributions from the community, I could totally see us expanding into other areas. The engine itself is written to have an embedding API so if you're familiar with C++ you could totally start creating a non-mobile solution with Flutter today.

You don't need a treaty to enforce the law, you just need a pizza shop owner who likes to vacation in europe sometimes. You carry out the default judgement if they ever arrive in the EU. The GDPR explicitly has a very global scope because it is targeting companies in and out of the EU.

I wouldn't really have much of a problem with the GDPR if it had some small business and non-eu business exceptions. It doesn't and regulators saying 'trust us we wont prosecute the easy to prosecute!' makes most businesses uneasy.

To the second question: it loses energy due to pair creation (iirc, surely simplifying due to bad memory).
Part of the cost is -documenting- what you're doing. Ensuring the right stakeholders are involved and signed off on it. Etc. When there's a regulation to do it, suddenly you have to involve legal, and the business stakeholders want to better understand it, whereas before it may have just been the developers.
You missed Xamarin, which seems to be popular enough to have its API documentation prominently ranked in search engine results, suggesting there seems to be .NET programmers doing mobile development.
> FCC Chairman Ajit Pai applauded the court ruling.

"In the months and years ahead, we look forward to working closely with the FTC to ensure the protection of a free and open Internet."

I'm glad they included this quote, because the media has certainly been _not_ reporting the complete facts with NN.

As for the question of "local ISPs are monopolies, so free market rules don't work", I have a lot more confidence in network innovation with the last mile problem. If we could transmit gigabit over wet twine, we wouldn't be worried about Net Neutrality because the install costs would be extremely low. I'd give the free market a chance to break up the monopolies first.. There's nothing I want to see more that Comcast going bankrupt and their CEO still wondering why "people are demanding more than 50mpbs of internet access".
Are you arguing with my point or just trying to be contradictory? I never said blocking the EU was a good solution, but calling it a single market makes it sound more enticing than it is.

> the MTA is kind of shit

The organization, sure. However, the transportation complaints seem to be more of a publicity stunt than anything^. I've lived in NY for 30+ years, NYC for 10 of that. Excluding a few subsections, public transportation as a whole has barely changed in my 15 years of using it (regarding the numbers, part of my time I did as a commuter from the 'burbs).

^ In regards to taxes. A summary of my comments the last time this came up:

NYC residents pay a ton in taxes and get little back. Our state taxes get moved upstate and our federal taxes go to poor states. I really think it's just trying to put pressure on our representatives to be a bit more "selfish" as to what happens with our taxes.

Both the MTA and Metro North are owned by the state. One of them has 300k daily riders, the other has 5.5m daily riders. 150k of those MN riders end up in the city everyday, so both groups are using state owned products, one group is potentially using BOTH (I always did when I commuted from Westchester to the financial district). The 4 commuter lines combined (NJTransit, PATH, LIRR, Metro North) have 1/3 the total daily ridership of the subway, but get almost double the amount of subsidies from state coffers.

Attribute language? I'm not sure what you mean.

In Go there is typically a very restricted set of ways to idiomatically accomplish a given task, often only one. Error management is a prime example.

result, err := function()

What do you do with err? If it is recoverable, you should try to recover from it.

if err == ErrTryAgain {
continue
}

Generally errors aren't recoverable, and should be reported back up the stack with some kind of contextual annotation.

if err != nil {
return fmt.Errorf("function failed: %v", err)
}

If you want to provide more context to your caller, to enable a richer set of responses to this error, you can use more structure.

if err != nil {
return FunctionError{Original: err, ...}
}

That's really about it. Anything that tries to subvert the very simple/plain `if` checking, or tries to perform some kind of monadic error chaining, or builds an ersatz exception system with panic/recover, is what I mean when I talk about "obtuse, clever, or dumb things". The language and its idioms form these expectations.
I guess this goes back to pg's essay on the messages cities send [0] that was posted here the other day. One person offered a particularly insightful comment on the message of my city, Dallas. I'll quote the most relevant part:

I can confirm that the culture here is very 9-5. We don't have the ambition-centric culture that SF has, and that works for me because I'm honestly not an ambitious person. You're probably not going to find many people here who are trying to grow their own business on the side or who go to a bar still trying to work through problems they're stuck on at work. I go to the bar when my job is stressing me out so I can forget about the stress by drinking tasty alcoholic treats until I can no longer concentrate on anything.

If fewer people are killed in auto accidents, it’s a win even if the type of error is different. Dead people is dead people.

Why are you surprised? People are cool with massive metal murder machines flying down roads just because it’s a human driving it and not a computer? I seriously can’t wait for all us flesh drivers to be replaced with computers. The thing is that over time computers become better and better drivers. Humans don’t, actually we just get worse as we age and stay on the road anyway. Our human reflexes and biology also limit how fast we can react and subject us to road rage, stress, fatigue and other problems that can’t be debugged. Why is it worse to have software that we might actually be able to fix?
