In terms of cosmology, the physically observable universe does have (some) fractal structure or features--, primarily to the existence of multi-scale primordial (quantum) fluctuations.

On the other hand, at very large scales the universe is expressly homogenous (smooth)

W/r to larger and more wide-ranging questions, e.g. if the mutli-verse has some sort of deep fractal meta-structure, and/or the recursion of fundamental quantum computing operations, the jury is still entirely out.
The Dockerfile language has some very frustrating limitations.

One I've found frequently frustrating is the inability to do any sort of globbing on COPY commands. This can make it very difficult to do some types of layer optimizations. For example in the Java world I have multi-project Gradle builds which consist of a tree of directories each of which contain a "build.gradle" file. I would like to copy all of these files, preserving the directory structure, into the container so that I can run a preliminary "gradle assemble" command which installs third-party dependencies, then only after that copy the remaining contents of these directories. That way I only need to re-download dependencies if any of the "build.gradle" files change when building the container.

This turns out to be impossible to do in the Dockerfile language without manually listing out every "build.gradle" file in the directory tree.

This is fun to see and all, but what has this got to do with 'hacker news'? There is no in-depth information about how it was built, how it was programmed or something like that. It's not a new concept, this has been done a lot of times. The video isn't even new, it's from january.

I really don't mean to be negative, but I just don't see why this is on the frontpage of hacker news.
Sadly "Reuse" has found no reflection in the laws and practices in most industrial countries. For example, giving replaced lab equipment to hobbyists is a perfect way of reuse, however, very few companies do that. Most rather send everything to the crusher or exchange it with the manufacturer for a discount who will do the same.

Here where I live there are both supermarkets with modern supply chains as well as roadside stands and small markets who buy local, so we're not particularly screwed by our Western society. About 30 miles from me is a valley that supplies tons of produce during the spring and summer. They don't grow tomatoes or peppers, but I can source all of my other ingredients locally. Winter would be troublesome but I've usually got enough dry goods to get by for a few weeks.

I recently finished writing a tutorial on using the AccessManager interface in Javalin (https://javalin.io/documentation#access-manager).

They have amazingly intelligent people and a wonderful hacker community, the problem is it stands entirely at odds with the government's "what's best for society" attitude. The problem most overtly controlling government's aren't willing to accept is that what's best for society this exact moment might not be what's best for it overall. This is why there's no Chinese technology leaders, no Chinese Apple. Communism brews mediocrity.

QWERTY keyboards actually aren't the optimal layout. Dvorak is generally considered to take first place on that one. QWERTY was an arrangement that kept the hammers from jamming while still minimizing finger movement.

Minimizing finger movement is still important, even when only using two fingers on a smartphone screen. Although not as significant as it would be on a full size keyboard, all of those extra little reaches add up.

Of course it's still hackable. There's nothing stopping you from advertising specific prefixes and hijacking all of Youtube traffic globally.

https://dyn.com/blog/pakistan-hijacks-youtube-1/

Oh wait, that happened almost a decade ago, and there's been no fundamental change to the protocol to protect against that. Except, if you keep something like that in place persistently, nobody will want to peer with you.

* My understanding is that the global hijack was accidental. Pakistan Telecom just wanted to block Youtube traffic internally, and they used a bad mechanism for doing that. Oops.

I agree that you can make significant savings with G12 tariff in which night usage is about 30% cheaper than during a day in comparison with fixed-price G11. But unless you have your own source of renewable energy your car will be charged with power from coal power plant. So maybe you can charge your car for less but you still use fossil fuel and it doesn't change much in amounts of emitted CO2.

I refrained for a very long time from using facebook and whatsapp - but relented to using them. I also actively researched ways to get rid of the google ecosystem - but what i realised is that, you cannot be on another ecosystem, if people whom you want to communicate with are using the very ecosystem you want to avoid. Its a collective problem and unless everyone is aware of the perils of using them, people who care / worry about these things are in the minority and unable to convince the majority to refrain from using google / facebook.

I have been getting a lot of stares for suggesting to people to not use facebook.(I finally put a facebook profile last year but am not active on it. I rarely login to facebook).

All the people i wanna communicate with are on whatsapp - i have no hopes of convincing people to switch over to signal and i have given up this pursuit.

I am tired of endless conversations to explain to people about the "bubble" and also the privacy issues that come along with using these products (we are the product anyway).

Worse, after all the convincing arguments i submit to people, people nod in acknowledgement and use those very products anyway. It's like noone cares. And i found myself increasingly isolated for quite some time, and finally relented to using fb(rarely)/whatsapp(use it like an sms app
- i have exited all the groups).

Voltage droop is a real issue for many cables not just USB ones.
It's a much bigger issue when you use them for power, it's a pretty well known issue that cable length and gauge can have (a pretty big) effect on charge speeds.
It's even a bigger issue on the higher end devices that will limit the charge not only based on voltage but also on current, basically if the cable can't deliver the the 2 amps they'll drop down to 500ma or even lower.

I've switched most of my USB charging cables to those which I know are 20AWG, the funny thing is that these cables aren't even more expensive I got mine from http://www.portablepowersupplies.co.uk/ and they are cheaper than most cables on Amazon....

>The problem with image based languages is that you've thrown away your file-based tool system. You're so used to your favorite text editor, source control system, etc? So sorry, we're building better tools! And when your code is ready, you just deploy the image!

First, what's bad about that? Our text editors and source control systems are indeed crap compared to what we could get with image based systems with inherent (not text-level) knowledge of code. The only real argument is that we still need to work with legacy crap text-based languages also, which can't share those tools. But that's not really an argument against those tools being good in themselves.

Second, there's nothing about an "image based language" that says you can't also have a textual representation, and thus work with your editor (or the image based editor) and "regular" SCM tools.

Third, LISPs are generally not image based.

Interesting. I thought another purpose of the second hose was to help the displaced air flow out of the tank as it's being filled, allowing higher flow rates without the fuel backing up and spilling out.

Modern cars have on-board refueling vapor recovery (ORVR), but plenty of people still drive older cars. I think it's safe to say that the combination of a pre-ORVR car with a dispenser that doesn't have Stage II vapor recovery is a real possibility.

That sounds like the system with the carbon canister ("evaporative emissions") and sealed tank cap, which has been around since the 70s. It would have to be a very old car to not have that.

Extended stay transfer visas on arrival are not uncommon. Moscow has this, as does Hong Kong for mainland citizens without entrance permits. So if you fly to Europe from Asia via Moscow and have an extended transfer Moscow, you can get a visa on arrival to see the city for a day or two, or if you are mainland Chinese and fly to Bali via Hong Kong, you can have a one day layover and see Hong Kong even without a Hong Kong visit permission.
Let's get realistic, shall we? Any new jet costs billion plus USD to develop. This was even true for the Russian Sukhoi Superjet 100, even more so for the Bombardier C Series. And these were relatively minor adjustments over existing tech, not an entirely new design for faster-than-sound travel. If you consider groundbreaking planes, like the 787 program, that was 32 billion.

Boom, according to Crunchbase has raised $35.24M in 3 Rounds from 13 Investors. That's ... nothing. A rounding error in the budget to develop something like this. The CIA reportedly spent 3.7 billion to develop the SR-71 engine. And that was really long ago. What do you want to do with 35 million? 35 billion would be a much, much realistic number.

This is not an industry to disrupt. If you intend to fly in the UK, EU, USA, Australia then you need to certify with the FAA/EASA/CASA etc and you can't pull a fast one with those.

https://arxiv.org/

As suggested here, perhaps consider writing up and submitting a short article to arxiv. That ought to be enough to ensure credit. If you don't intend to patent it (don't know where you are located & local laws), the arxiv preprint service will give you a citable, dated & externally validated submission that you can use. It wouldn't be peer reviewed until you submit it to an appropriate journal, but that's a relatively short step away once you upload the preprint to arxiv.

I didn't like the original comment "everything moves through spacetime at c.". I was trying to write a reply, but I saw your comment.

I think your comment is too long and too technical, but it's correct and explain why the original comment is wrong. So I upvoted it.

The problem is that is too long and too technical, so the main ideas are lost and many people prefer some wrong handwaving.

Some recommendations:

* Try to keep the answer shorter. Link to the Wikipedia article if possible. Perhaps ignore part of the original comment to make the reply shorter.

* Try to avoid too much technical jargon. This is a technical forum. You can assume everyone has Calculus 101 and Algebra 101, and a few more elementary courses, but nobody has advanced knowledge of all the topics.

It's difficult to explain in simple words why I don't like the original comment. The answer is strangely in one of your other comments.

> "Sure, you can always choose useless systems of coordinates."

It's too short! I'd try to add some details: The problem with "everything moves through spacetime at c" is that you must "sum" the squares of distance "x" in the laboratory reference frame and the time in the reference frame of the moving spaceship "s" (and fix the units, sorry). So you get a nice property that is valid if you use properties that are measure in different reference frames. But 99.99% of the time, life it's much better if you don't mix measurements in different reference frames.

[My version still needs a lot of fixes, fix the units, perhaps replace "reference frame" with "astronaut", add at least a formula, ... I guest that with 1 or 2 more hours I can fix it, but this is a deeply nested thread that nobody will read and I have to go to eat ... https://xkcd.com/386/ ]

> necessity to have filters on both sides of an EBGP session. In this case it appears Verizon had little or no filters, and accepted most if not all BGP announcements from Google which lead to widespread service disruptions. At the minimum Verizon should probably have a maximum-prefix limit on their side and perhaps some as-path filters which would have prevented the wide spread impact.

Wow that's just stupid on Verizon's part given the magnitude of potential impacts.
The batteries being talked about are 18650s, which is mentioned pretty clearly in the article and apparent from every single picture of batteries in it. This makes sense, because the vast majority of laptops sold across the world use a set of 18650s as their batteries. These are also the form factor of batteries being used in current Tesla powerwalls (though I believe they will also switch to the 21700 form factor as production of that ramps up).

18650s are just as safe as any other battery chemistry in everyday use, but they're a high energy lithium cell. In particular, if you do bad things to them, they may light on fire. It's not that hard to take appropriate precautions to avoid that, and reasonably sized lithium-ion battery fires can generally be put out with a standard househould fire extinguisher.

It also appears the community is collaborating to spread good information about powercell design to avoid/manage fires inside the units, in the unlikely event a cell starts a fire. If the container for the powercell is designed correctly, it can contain a complete unit burndown: https://electrek.co/2016/12/19/tesla-fire-powerpack-test-saf...

In short, you're overestimating the risks and underestimating the level of safety attainable with these products.
To be fair, whenever they bring out the special tools, it's generally preempted by "if it doesn't work it's on you."
I guess this definition of coding harkens back to the days when secretaries* would encode programs written by mathematicians by punching cards or weaving knots or configuring wires?

Because that hasn't existed in a long time, at least since the 70s. Much like typesetter don't exist anymore where designers use programs that allow the, to typeset themselves.

* many of these "coders" like future rear admiral Grace Hopper got fed up with this and did something about it, leading to the first compilers and programming languages.
How competitive forces shape strategy (1979) [pdf]
How could the 27 file commit example comment not be a clear case of overengineering though? I frequently add similar functionality to Vue and Angular 1 projects in a way close to how you describe and it's simple. Even if the change involved adding a modal library (you should not be wasting time implementing that yourself) to your project first, it shouldn't be more than about 10 lines.

Personally, I'd find it very hard to be motivated to work on a project like that. It sucks all the fun out of coding when things that should be simple aren't simple, it's draining for the whole team and it creates a lot of friction in adding new features.
