It has squared off corners in the front... I know nothing about boats, but couldn't he have have reduced drag a bit by at least rounding off the front corners or cutting them off at a 45 degree angle -- I'm not suggesting tapering the entire front, but just rounding off 6 - 12" from the edges seems like it would help? This would reduce the interior space a bit but gaining even 1% better speed on a 90 day journey seems quite significant.

The only similarly shaped hulls I can think of are barges, but they are towed by 1000 horsepower tugboats.
It's worth pointing out Qantas is the exception to your point. More incidents on Qantas flights are due to causes outside of the crew's control than due to human error. Even then, Qantas hasn't lost an airframe or had any fatalities since the dawn of the jet age.

How much would the low earners win or lose if the minimum wage laws would be strongly enforced? My estimate is that they'd lose close to 100%.

Who would hire somebody for 15$/h if the worker is able to only produce 9$/h?

If the law is the only factor to decide the minimum wage, why not setting it to 50$/h, or even 100$/h? Are the politicians and the policy makers really so evil that they like seing workers people struggle at 10-15$/h?
Thought it may have been because of a different API but looks like the service worker is configured to always return the fastest retrievable data, hence why it's obtaining stale data from the service worker cache.

These particles (anyons) live in two dimensions, so their world-lines trace out paths in three dimensions (two space dimensions and one time dimension.) These world-line paths get braided or knotted, just like hair does. And even though your hair gets jiggled around by the wind (quantum noise) those braids remain intact (the quantum information is preserved.)

Edit. For the very bravest of five year olds, I wrote a paper on these things here: https://arxiv.org/abs/1610.05384
I agree completely. I lived there too and was skeptical too, but the end result is really wonderful. It's probably one of the best buildings in Hamburg now.

To give some more context: Many of Hamburg's larger buildings are built in a way that is supposed to resemble ships, and so is the elbphilharmony. The bottom of the building is actually an old "Kontor" (depot) building in the harbor (before: http://www.fotograf-hamburg.de/02_bilder_hamburg_speichersta...). From there it has these sail-like structures on top.

I believe the $8b figure is actually referring to just wage theft via minimum wage violations, in the 10 states analysed in the study. The totally amount lost to all forms of wage theft across the US is likely much, much higher.

From the article: "In these [10 most populous] states, 2.4 million workers lose $8 billion annually (an average of $3,300 per year for year-round workers) to minimum wage violations."
Beautiful! I would love to see an animation of it in action (a la https://bost.ocks.org/mike/algorithms/)!
Scratch that, according to this issue (https://github.com/Polymer/hn-polymer-2/issues/3) it may not be an API issue and is probably because of stale service worker data not being refreshed.

Sorry for the lack of clarity, I was referring to the combination of unemployment rate and workforce participation rate (which is 74% with bachelor's degree or higher, 58% with high school only). There's doubtless some confounding factors there, but it shows where the jobs are going. I don't think those inherent difficulties for certain people you mention don't need to be considered separately because the market doesn't care why you didn't attend college - part of what the market is rewarding is, frankly, either not having or being able to overcome inherent difficulties.

Right. Like, say, capital punishment.

Horrifically inefficient. But hopefully effective for a larger audience.
> Except that this is ALSO a failure mode

Yes, it is. But in the Air France incident, there was faulty data from the airspeed indicators; the computers were incapable of flying the aircraft under those conditions, so there was no choice but to let the humans try. They failed, but that's not an argument for not letting them try if the computers would have also failed.

In the Quantas incident, there was no faulty instrument data as far as I can tell; it was just a computer crash. So the human would have done fine if only given the chance.

> The programming needs to start assuming that it gets no help but needs to recover anyway.

How can that happen if the computer crashes? Or if the instruments are giving faulty data? Unless and until we have artificial intelligence equal to that of humans, I don't see how you can not have a way for the human to have some last ditch way of overriding the computer, since the human at least has some chance of handling conditions that the computer simply can't.
Not sure why I was down voted, is it well known that the common tapered hull shape is not any more efficient and faster than a squared off hull?

I didn't see any details in the article or website about the design other than that it was designed to pitch rather than roll, and tapering the front seems like it would just add to this effect.

I wish the downvoter had just said "Dumb question, everyone knows that hull shape doesn't matter on a small boat" or "He covered this exact question on his website" or given some indication why they felt this was not an appropriate question

How to Opt Out of Twitter's New Privacy Settings
Let me rephrase 'what's the point' to 'have any meaning'. I think that captures what you're trying to get across, but i could be way way wrong (please enlighten me if i am wrong). Why on earth would someone waste time on such a meaningless activity?

Meaning is a really hard thing for me to pin down. Most people go to work, not because work is fun, but because they want money. to them, it's real, meaningful security. It's a place to live and food to eat. The 'meaning' is pretty clear. Some of those people work to provide for their families. These are pretty clear, easy examples.

I screw around reading hacker news, and getting into discussions, because sometimes they're really fun. The meaning, for me, is exposure to other viewpoints and ways of thinking about the world. I do have to admit, i'm probably getting my life sucked out of me doing this, five minutes at a time, with silly comments like these. But i rationalize and such, and invest these conversations with meaning.

As far as i can tell, there's really only two possible ways to have meaning. Stuff that i think is important (poor word choice. Stuff i'm perhaps emotionally invested in, or enjoy, or am attracted to). The other way is theological. I'm not a theological person, so i'll set that aside as meaningless. But i'm happy to follow that sort of argument if you want to make it. Again, i'm here for the viewpoint, because that's the part that has meaning to me.

Perhaps this is all rambling nonsense. I'll try to make some sort of point. Do you do anything meaningful for a reason other than it's important to you or (maybe) your god? For any reason you pick, i can find you a person that made a different choice. For example, you chose to spend some time on HN tonight. I can guarantee my mom didn't spend any time on this site.

You (or maybe your god) invests the world with meaning. You get to pick how to spend your day. I get to pick how to spend my day. We probably don't make the same choices. The boat guy, he makes very different choices than both of us. But that's ok. The choices we make probably look just as pointless to him as his choices do to us.

We'll all be dead soon enough. I'd encourage you to let people doing weird stuff just be weird - as long as you feel they're not endangering the rest of us somehow. That guy is going to try a crazy thing. I also think it's meaningless. But it's not meaningless to him. I'd suggest that criticizing someone for trying a meaningless thing is even more meaningless.

you're going to die someday buddy. Do stuff that means something to you.

so only way i am gonna consider US over these is if they will be extremely friendly to visitors and stop all kind of this laptop ban bullshit (no way i put it in checked baggage) and million questions ESTA or if someone will give me air ticket pretty much for free
It is true that "running sections" has gotten more efficient, but that has nothing to do with education. Lectures have repeatedly been shown to be the worst method of teaching, and being able to speed up exam grading does nothing for that. It's also impossible for our lone professor to grade homework in a mega-section without an army of TAs (who cost money).

> Even then, Qantas hasn't lost an airframe or had any fatalities since the dawn of the jet age.

They do have a record as a safe airline ( though Southwest and Ryanair are probably 'safer' given the number of short-haul daily flights they operate ) but QANTAS also go to extreme lengths to maintain that reputation.

For example in 1999 one of their 747s, reg VH-OJH, overran the runway in Bangkok after aquaplaning. The insurers examined it whilst it lay on a golf course and wrote it off as uneconomic to repair. QANTAS however decided to proceed on its own initiative, to maintain its 'no jet losses' reputation, and spent over $100 million on repairs. Probably more than or just about exactly what the aircraft was worth at that time.

They actually had another 11 years service out of that one before it was sent to Marana for storage.
Most important takeaway for me was "fail faster". He talks about the first two attempts going on for a year and a half and burning through 5/6th of their money before they hit product market fit.
There are other ways too, like requiring employees to pay for parking...

Unless you're talking about requiring employees to pay for parking which they're not using, this is not wage theft. To the contrary, the inequity would be if free parking was provided to workers who drove to work but no similar subsidy was provided to those who took public transit. (In Canada, free employee parking is in most cases a taxable benefit.)

Keeping status quo without an explicit human override while notifying humans would have been FAR more preferable.

Once common thing in all these failures is that the derivative of these readings/settings has a spike.

These are passenger jets. They have envelopes; they behave according to physics. They don't do anything suddenly.

Sudden anything should get flagged as a mistake and ignored until corroborated.

> How can that happen if the computer crashes? Or if the instruments are giving faulty data?

You have voting and redundancy for a reason. 3 votes is not enough. The space shuttle has 5 computers of which 4 are active and voting.

Embedded computers can and do reboot within milliseconds if that is part of the spec.

The real problem, I suspect, is lack of testing. Especially of a fully assembled system whose parts have come from disparate suppliers.

Once you take the attitude "The human cannot help you out" your testing regime needs to get a LOT more stringent.

If I understand the abstract correctly, that relies on having a trusted compiler, which assumably would have to be bootstrapped ultimately from a trusted hand-written compiler in machine code. This effectively counters malicious trusting trust attacks but does not effectively counter trusting trust attacks due to error, because your entire trusted stack has to be correct.

That's not to say there's no way to close the loop here, simply that I don't know that this is it.
Some 'anecdata': 2 people I've known personally basically seem to fall in the category of "my credit score is 300 and bill collectors call but I don't make enough money so screw them I'm not paying." Just because someone attended college doesn't mean they have made wise decisions about taking loans and what to study (if they've even finished a degree). That $5 is towards a pack of cigarettes or gas for their car, why would they 'give that away?'

Then they go into rehabilitation with minimum payments, so they can get more student loans and not pay those back either. And the saga continues

Rather than rebut this in detail, let me just suggest that you study economics before spouting off. It's fun to speculate about numbers, but there is real research and real models to describe these dynamics.

I'm not an economist... but at least I know that about myself.
In case you were wondering, this is super transphobic.
I am a pilot, and my complaint is not the lack of a last ditch emergency manual mode, but that there are numerous modes (or alternate laws) in the software abtraction of fly by wire aircraft, and the plane responds differently to inputs in these different modes, the notification for what mode the system is in has to be inferred, and the pilot is expected to know all of these things.

I think it's hubris and incompetence in engineering that a system would be designed this way. And in fact not all of them have these same deficient behaviors, so this is not inherent to fly by wire or automation. It's a choice made by the software abstraction designers.

The idea there'd be a mode where advancing a throttle literally does nothing, no increase in power nor a notification that the input received is sensed but isn't going to do what you think it should so that you have a clue in that some other mode is applied, is so totally batshit insane to me. It's a huge betrayal of physics of flight which is something pilots do understand rather well, almost like muscle memory.

In a conventional plane, throttle advance always increases power. If that doesn't happen, it's an emergency. In a fly by wire plane if it doesn't happen, it almost certainly means the pilot is confused. And that to me is crap design.

> the computers were incapable of flying the aircraft under those conditions

Perhaps so, but a safe method of flying the aircraft under those conditions were known, and could have been programmed. "When airspeed indication fails, fly at this power setting". The computers handed over to humans, knowing exactly what indicators were faulty, as programmed with the intention being that they're better at dealing with this kind of situation; it turns out that they are not.

Yeah, but the principle is the same: what happens when the worker is not able to produce to the level of the minimum wage? be than 15$/h, or 7.25$/h.
Would you pay somebody 7.25$/h if they're able to only produce 5$/h?
It's actually an open mystery why unemployment is so low, but we have yet to see much upward pressure on wages. Theories I've read (probably in the Economist, definitely at the NYTimes) is there is still hidden slack in the labor market from people who dropped out during the recession, and are gradually rejoining as the economy grows.

The link between supply and demand -- and prices/wages -- is really messy, though. I mean, downward nominal wage rigidity is a big deal (and is well documented). The labor market is nowhere near efficient.

So no, the UI rate is not some fake statistic, cooked up by government agencies... it's just a noisy statistic for a messy market, whose relationship to 'price' (wages) is nonlinear, laggy, etc.

(I think.)
That seems like a very error-prone solution.
None of them are ready to use in a serious capacity yet.

Based on the Filecoin announcement, they are building something very similar to Sia. It appears to depart from traditional Bitcoin proof-of-work consensus though. I'm looking forward to reading their whitepaper.

"Elementary particles are elementary excitations of the vacuum, which explains why they are identical." (pg 4 ref 3) Is this now accepted fact, everything is a wave and there are no particles?
The dynamics are considerably more complicated when you consider massive public policy decisions that affect the labor market, like changing the minimum wage. When you're pricing widgets, you can look at marginal value add and have it make sense. When you're talking about the floor of the labor market, you're really talking about economy-wide effects. The main knock-on effect of raising the minimum wage should be inflation; most labor costs (at least those that get built into consumer prices) are in some way linked to the minimum wage (either explicitly, or because of implicit pay scales).

So yeah, there are considerations. But it's not that kind of mechanical, subtract-marginal-value-of-employee kind of considerations. Unfortunately, economies are big and complex and require sophisticated models (they can be simple -- but they should be sophisticated).
