You're wrong. The Triangle Shirtwaist fire was a result of the economy being primitive at the time, with very little resources available per capita for risk reduction. Work place accidents were decreasing every single decade before cookie-cutter work safety standards were mandated. The world today would be extremely safe in and out of the workplace in the absence of such mandates.

This bias toward central economic planning and mandated standards is a consequence of the great complexity of a modern economy not being appreciated by the typical person. Central economic planning is based on oversimplifications that are easier to reason about.

As for the Ludlow Massacre, that was largely a result of illegal and violent actions by unions. We don't have those anymore, because unions impose their will through political decree nowadays.

Most teachers in the United States are unionized, and an increasing percentage are under collective bargaining agreements, to the great detriment of education:

https://academic.oup.com/qje/article-abstract/111/3/671/1839...

The education system is consequently heavily biased toward unions and their dishonest narrative. Here in BC, teachers openly tell their students they hate the governing party (which stood up to the teachers union) and kids almost uniformly hate the governing party as well.

It's absolutely ridiculous.

It could still be useful if it could charge your phone/laptop all the time without you needing to worry about or manage it. And in that case it doesn't need to be as efficient as a wire since it can start charging as soon as you get home until you leave.
Hell, inattention for less than 3 seconds at the wrong time can cause a huge accident. Then there's the issue of willfully bad driving when it comes to sports cars, bad weather, and drunk driving.

OK, so if the spammer wants you to call back, they must leave a number. So say, if someone offered suitable SaaS, you could put that number on a list to be voicemail spammed. At one minute interval, from random numbers.
Who is "expecting" anything? Who mentioned mere "deserving more"? Questioning something and seeking to change it is a long shot from what you're conveniently and predictably framing it as, and in context "leaving for another company" isn't even a joke, it's a tired old chestnut beginning to become offensive.

Don't expect sympathy saying your mind is boggled while spending more effort to misconstrue than to understand.

Well, I hadn't exactly predicted it — the quoted joke was from the top of the site's FAQ page, meant to imply that users of the service would get in trouble for being complicit in copyright infringement / piracy — but it also wasn't all that surprising when it happened. I was sued by the current Napster (https://en.wikipedia.org/wiki/Napster_(streaming_music_servi...) for alleged trademark infringement.

In the end we settled before it ever went to trial, so unfortunately that quote never found its way into a court transcript.
It all depends on the service the train offers. If it helps people to get to LAX faster or any other destination to a reasonable price it will win.

Also if you build the route and avoid cities of almost half a million people you can't really fix this later without building a new route.

It is not just about infrastructure about also about access to the infrastructure.
>If an employer really wants to hire non-union labor, they can leave their company and join a different one that doesn't have a union.

This makes no sense. The employer shouldn't be forced to 'have a union'. It's not a voluntary relationship, and thus it totally violates the company owner's right to their own private property.

Unions as they exist today are rent-seeking organizations that prey on employers. No wonder investors invest in other countries, and companies outsource.
I guess that would be a sensible argument except those people aren't exactly carrying the state on their backs. Santa Clara County has only twice the population of Fresno County, but it pays 15x more in state income taxes. State revenue in general depends almost wholly on the Bay Area, LA Basin and San Diego counties.
Thanks for providing the link to the documentation in Racket. For people like me who don't know how to program in Scheme, this quote from the documentation might make it click (it is at the end of the page):

Keywords are intended for use (unquoted) as special markers in argument lists and in certain syntactic forms. For run-time flags and enumerations, use symbols instead of keywords.

This is fake. They got some gullible reporters to plug their phones into black boxes, which are supposedly receiving power. In reality, those boxes contain sensors to tell them when to pretend to receive power, plus batteries.

If it were real, they would've given the demo to someone with technical sophistication. They wouldn'tve bothered taking a trip to a phone store, since all the observers already had their own phones. And, also, the laws of physics would be slightly different.

But this scam isn't aimed at us. It's aimed at investors, who will never read this Hacker News thread, or any other thread where smart people are around to debunk it. Because if they did read that sort of thing, they wouldn't be an investor.
The route is literally written down in a constitutional amendment that passed a plebiscite with a supermajority. It is entirely fatuous to claim that the route "doesn't matter".
I'm certainly not long on uBeam (even after this fragile demo), but what physics dictates that it won't work? Sure, you're certainly going to take an efficiency loss, but wall outlets already output far, far more power than your phone uses while charging, so the real questions are how inefficient is it, how safe is it, and how convenient is it (can a final product survive if it needs line of sight?). While these are certainly very difficult and perhaps intractable engineering problems, I'm not aware of a fundamental physical limit on any of these that would limit an application like phone charging.
Yes, there is doubt about whether it works.
HSR is a great example of what happens when a bunch of coastal elites look at the countryside ("flyover country") and assume it's empty and worthless so nobody will object if they run a bulldozer through it for a big government project.

On the contrary, California's Central Valley is one of the most vibrant and important areas of the state with property claims going back to the homesteading period. So shocking that these people aren't happy with a bunch of LA and SF people wanting to tear up their back yards for a boondoggle they will never use or care about.
I wasn't saying it wa snot a factor, and I totally agree with you, but the inverse square law per its exact definition does not apply here.

I think uBeam is another Theranos, but granted at a much smaller scale. Still can't believe it has raised so much money and so much press without basic questions really being answered.
Ask HN: Dashboard tool that displays data along time series?
I am looking for a dead simple dashboard service that displays a chart with data points along a time series. Let me explain: I want to just push the cpu load of my server to this service every minute (via REST or whatever)

when i open the dashboard, it display the trend on how the cpu load changed in a nice line chart. I can also drill down to see the exact cpu load in a particular point of time.

Replace CPU load with pageviews or whatever. I dont think the metric should really matter. I am not loooking for something complex with bells and whistles like Klipfolio. whats the easiest tool that can do this?
> It could still be useful if it could charge your phone/laptop all the time without you needing to worry about or manage it.

And without you using it. As soon as you start using it you'll be back to normal, and likely there would not be enough power to put a meaningful charge into anything the size of a laptop with this system.

Unless phones are going to use a small fraction of the power they use today I don't see this working in practical setups.

> And in that case it doesn't need to be as efficient as a wire since it can start charging as soon as you get home until you leave.

10 seconds plugged in to a wire would give you more juice than an hour or two hooked up to those transducer arrays.
This comic is really pernicious because it frames free speech as just a quirky law that restrains the government.

That's like saying honesty is just about not breaking perjury laws in court.

In reality, free speech and free inquiry are social virtues that, like honesty, should be applied and upheld at every level of society, public and private, commercial, academic, and personal. Because free speech is a key mechanism to reach consensus and keep society functioning.

This is becoming even more and more relevant as our "public squares" of discussion are no longer government-owned physical public squares, but rather online fora owned and controlled by mega-corporations.

It's disturbing enough that Facebook or Google could easily turn an election on their whim, and it would be legal. It's even more disturbing that a whole lot of people are loudly proclaiming that this is fine, totally okay, and ethical, just because they think their views will never be the ones that get silenced.

So yeah, that cartoon is terrible.
Seeing this kind of analysis on the needs of employees makes me feel like these folks really care about their employees. More importantly, they know how to act on it.
They're not the same arguments at all. The corollary would be if you started working for a company, and the company then created a union with other companies, and made it illegal for you to work for any company other than those that are part of this corporate union.

In a free society, a company would be able to fire its workers for unionizing and hire new ones.
Wish you the best. Also people who keep complaining about other people's privileges should read this several times. People rising from bottom to top is more common than we think.
I wouldn't want to be in that office on 'bring your dog to work' day :-)

I find these stories fascinating not by what they say about the technology but more what they say about the state of education in engineering these days and the ability to believe the impossible is possible. I wonder sometimes if someone told these people "if you can imagine it, you can BUILD it!" and they took that statement literally.

There has been a tremendous amount of work in energy harvesting from ambient sources which is really pretty amazing. There was a fun paper on harvesting sound for energy in 2013 [1]. The key of course is how much energy and at what efficiency.

The CEO's point was that if you can charge anywhere you don't need a full charge, you just top off. It would be interesting to see if it can charge while being used (so net positive charge). In the video at least you can see their device for showing the beam footprint.

I'm also wondering "why talk now?" clearly burned by previous skepticism, why not just wait until you have a fully realized product or are they doing a fund raising round and need some outside validation after their disastrous first go?

I'm betting in the summer they'll be happy to occasionally take the high speed rail into LA to go to the beach. Hour and a half each way.
Unfortunately, the rise of frameworks has led to another, often ignored problem: app startup time. Carthage and CocoaPods, while great tools, became enablers and I'm hoping static library support will be announced this WWDC.
> what physics dictates that it won't work

Wirelessly transmitting energy is fine. It's reliably transmitting a meaningful amount to tiny, moveable objects near people that's the problem. You end up with unfeasible combinations of tracking, safety and efficiency issues. Serious work on remote power transmission doesn't start with consumer devices.

Well, you would be correct to say that Kube-DNS is a "cluster add-on." However, something being a cluster add-on doesn't make it not part of Kubernetes. It is no less a part of Kubernetes than kube-proxy. As far as I can tell, the difference is that cluster add-ons run _within_ the cluster, alongside other services. With no cherry picking, here is a quick excerpt from the Kubernetes README about cluster add-ons:

> Cluster add-ons are resources like Services and Deployments (with pods) that are shipped with the Kubernetes binaries and are considered an inherent part of the Kubernetes clusters.

I do not think there's a standard set of cluster add-ons that are guaranteed to be installed in any given setup, but thus far I've done a few Kubernetes deployments and it seems the following come by default anywhere:

- fluentd for logging (w/ StackDriver on GCE and ELK elsewhere)
- kube-dns for dns
- grafana + heapster for container metrics
- dashboard (of course)

Re: load balancing. Calling Kubernetes Services poor man's load balancing seems rather disingenuous. Sure, it's layer 4 load balancing and it is round robin. However, being lower level does not make it useless. In fact, I have some production deployments that are not HTTP. Kubernetes does have a primitive for layer 7 load balancing and routing for HTTP, in the Ingress resource, which admittedly is not complete yet, but I'm grateful that they support layer 4 natively. It does just fine with our production deployments even though it's "purely round robin." Most of the time, pods under the same service will have roughly equal capacity containers, so round robin is usually fine. And as far as "poor man's load balancing" goes, it provides liveness and readiness checking, something that I'd consider to be useful alone, versus say DNS-based load balancing.

I think in some ways your line of thinking punishes Kubernetes for having a somewhat modular architecture and that sucks. If you have a setup that actually does lack ELK or Kube DNS by default with modern versions, then sorry for misjudging. However, I have not seen this yet and haven't seen anyone use Kubernetes without Kube DNS since I started.

Yup:

Dude.
How do these problems even compare? NTSC is incapable of reproducing any! movies native frame rate, resolution and color space faithfully. It's that our expectation of consumer media have changed.

Broadcasters seem way less inflexible as the were back then, with television devices no longer costing multi-month salaries in most regions and whole standards like analog transmission and DVB-T 1 being already phased out and the current replacement rates being somewhere significantly under 10 years. Breaking legacy standards is no longer a no-go.

BluRay is not the problem, the display devices which support only older HDMI standards are, then again their whole hardware capabilities rarely exceed them either.

I doubt to see another consumer standard gaining any widespread adoption for physical distribution, when YouTube does already stuff like 8k@60fps and beyond. The expensive part now are the +4k display systems, not their media boxes (fire sticks, chromecast, set-top boxes, gaming consoles), which are cheap and can handle almost anything they have compatible hardware decoders for.

There are UHD BluRay players for less than USD 200, it's up to the studios to release content

Not true. Any resource when used efficiently benefits whole of humanity. It is better if a boy from Ghana comes to USA and invents a vaccine to some disease than he stays back as just a doctor in this village.

People when they travel it is not an isolated incident. They tell their friends about the reality of other nations and then they aspire to be like other nations. We see it in India and China a lot.

Physical cash is a primitive technology so its use cases are quite limited given the superiority of alternatives.

Electronic cash in the form of cryptocurrency can make money transfer much cheaper than it otherwise would be. It also doesn't require you to jeopardize your privacy every time you form a financial relationship with a new company, as happens every time you use a credit card with a new company. In fact, your privacy is at risk every time you use an identity linked payment system, given the possibility of hacks/leaks.

I agree with the rest of your comment, but I would like to point out that absence of evidence of a revolution can't be evidence for an impending revolution (since you can't have it both ways).

No, the two calls are dialled concurrently with a skew such that call A finishes dialling moments before call B. Call B immediately goes to voicemail because the line is locked setting up call A. Call A disconnects before the phone starts to ring, but after the network has routed call B to voicemail.

Edit: clarified.
The real test is what happens after a ship explodes. Musk himself has said that you can't really improve the reliability that much. Cost is the only vector, and SpaceX is making spaceflight cheap.

It's still risky. If it's true that reliability hasn't changed at all, then it's even more likely that we're going to see a string of failures rather than a single isolated incident. That will be the true test: can we take that in stride, or will others get the last word?
Place this as another bullet point in the "luck plays a huge role" hypothesis with regards to success. Imagine how many other poor children in Ghana or elsewhere are just as capable of earning a degree from an elite institution but don't have the opportunity because of their lot in regards to where they were born.

If they think they will be able to raise again at that level without proper due diligence then they are smoking some heavy stuff. Anybody worth their fee will come fully equipped to an on-site job like this and will walk out with the required info: a nice set of data points listing power in and power out at a sequence of increasing distances from the transmitter and if they are thorough they do it with two receivers at a 90' angle from each other, and one run with only one receiver dead center.

If that delivers meaningful power within the typical usage envelope the tech is real. And of course you get to inspect the guts of the box to avoid 'gotchas' of the battery variety.
Had the same thing in the UK. They were desperate for me not to pay up front so they could try and sell me some other finance product that would cost me more / enable me to spend more without understanding the true cost.

This kind of credit for cars / housing / uni / whatever is just not helping people afford things they would otherwise defer buying. It's predatory. It's pushing up the price of items. It has no place in our society. It should be tightly controlled. Finance is pulling forward demand to get tomorrow's bonuses today and to hell with the consequences tomorrow.

If we want a better world we have to regulate debt issuance. Yes some kids from poor backgrounds can't buy a nice car even though they are doing a law degree at Harvard and will be able to cover it no problem in 3 years time. The flip side of the coin is far more damaging.

I just finished a couple of books that take approximately 17 hours on average. They cost me $5 each on the Kindle store. Hard to beat $0.3/hr. I also spent a few hours at a LAN cafe yesterday, at $1/hr, which is a reasonable rate here in South Asia.

Of course I could have gone to the library, but I read a lot more if the book is a tap away on my tablet.
