Tesla Model S driver sleeping at the wheel on Autopilot

RedSky says...

Woah, woah, you're way overstating it. The tech is nowhere near ready for full hands-off driving in non-ideal driving scenarios. For basic navigation Google relies on maps and GPS, but the crux of autonomous navigation is machine learning algorithms. Through many hours of data logged driving, the algorithm will associate more and more accurately certain sensor inputs to certain hazards via equation selection and coefficients. The assumption is that at some point the algorithm would be able to accurately and reliably identify and react to pedestrians, pot holes, construction areas, temporary traffic lights police stops among an almost endless litany of possible hazards.

They're nowhere near there though and there's simply no guarantee that it will ever be sufficiently reliable to be truly hands-off. As mentioned, the algorithm is just an equation with certain coefficients. Our brains don't work that way when we drive. An algorithm may never have the necessary complexity or flexibility to capture the possibility of novel and unexpected events in all driving scenarios. The numbers Google quotes on reliability from its test driving are on well mapped, simple to navigate roads like highways with few of these types of challenges but real life is not like that. In practice, the algorithm may be safer than humans for something like 99% of scenarios (which I agree could in itself make driving safer) but those exceptional 1% of scenarios that our brains are uniquely able to process will still require us to be ready to take over.

As for Tesla, all it has is basically auto-cruise, auto-steer and lane changing on request. The first two is just the car keeping in lane based on lane marker input from sensors, and slowing down & speeding up based on the car follow length you give it. The most advanced part of it is the changing lanes if you indicate it to, which will effectively avoid other cars and merge. It doesn't navigate, it's basically just for highways, and even on those it won't make your exit for you (and apparently will sometimes dive into exits you didn't want based on lane marker confusion from what I've read). So basically this is either staged or this guy is an idiot.

I'm very confused by that bit. Was that bunny hop activated by the driver (how?) or autonomous (and again, how)?

Although, I can't see it allowed on the roads. You could safely ignore speed bumps at highway speeds...

5 ways you are already a socialist

Babymech says...

Hahaha... seriously, what kind of passive aggressive bullshit is that? "Ignoring the theoretical underpinnings of socialism, because I've decided that that's waffling, I say Jesus was a socialist." Next time, maybe just write TL;DR and make a farting noise while rolling your eyes.

You can't dismiss the actual meaning of the word Socialist as 'semantics', if you're talking about whether or not something is socialist. That doesn't help the discussion.

In order to use socialism as you appear to be doing, you would have to first:
- ignore the history of socialism and its political development,
- ignore the entire body of academic work, current and past, on socialism, and
- ignore how the word socialism "IS used now, like it or not" in actual socialist or semi-socialist countries

By doing that you end up at your definition of the word, yes. But you had to take a pretty long detour to get to that point

Marx's quote on religion is pretty straightforward - it can be, as you say, open to interpretation, but it's generally agreed that he didn't say that your Jesus was a stand-up socialist. He is more commonly taken to mean that religion is a false response to the real suffering of the oppressed; religion provides a fiction of suffering and a fiction of redemption/happiness, that will never translate into real change. It makes the oppressed feel like they are bettering their lives, while actually keeping them passive and preventing them from changing anything.

The slightly larger context of the quote is this: "Das religiöse Elend ist in einem der Ausdruck des wirklichen Elendes und in einem die Protestation gegen das wirkliche Elend. Die Religion ist der Seufzer der bedrängten Kreatur, das Gemüth einer herzlosen Welt, wie sie der Geist geistloser Zustände ist. Sie ist das Opium des Volks."

I don't know how to make that more plain, but I can try. Religious suffering is on one hand a response to real suffering (wirkliche Elend, by which one would mean a materialistically determined actual lack of freedom, resources, physical wellbeing, etc), but it is also a false reaction against that real suffering. Real oppression creates suffering to which there could be a real respones, but religion instead substitutes in false suffering and false responses - it tries to tackle real suffering with metaphysical solutions. He goes on to say:

"Die Aufhebung der Religion als des illusorischen Glücks des Volkes ist die Forderung seines wirklichen Glücks."

This, too, seems pretty straightforward to me, but you might see 4 or 5 different things there. Religion teaches the people an illusory form of happiness, which doesn't actually change or even challenge the conditions of suffering, and must therefore be tossed out, for the people to ever achieve real happiness.

A fundamental difference here is that religious goodness is internally, individually, and fundamentally motivated. 'Good' is 'Good', and you as a Christian individual should choose to do Good. A goal of Marxism is to abolish that kind of fundamentalism and replace it with continuous criticism; creating a society that always questions, together, what good is, through the lens of dialectical materialism.

You might recognize this line of thinking* from what modern Europeans call the autonomous left wing, or what Marx and Trotsky called the Permanent Revolution, which Wikipedia helpfully comments on as "Marx outlines his proposal that the proletariat 'make the revolution permanent'. In essence, it consists of the working class maintaining a militant and independent approach to politics both before, during and after the 'struggle' which will bring the 'petty-bourgeois democrats' to power." Which sounds great, except it can also lead to purges, paranoia, and informant societies.

My entire point is that socialism and Christianity are entirely different beasts. One is a rich, layered mythology with an extremely deep academic and political history, but no modern critical or explanatory components.** The other is an academic theory of economics and politics, with all the tools of discourse of modern academia in its toolbelt, and a completely different critical and analytical goal.

TL;DR? Well, Jesus (in a lenient interpretation) taught that we should help the weak. Marx explained that the people should organize to eradicate the conditions that force weakness onto the people. Jesus
taught that greed would keep a man from heaven, Marx explained that religion, nationalism, tribalism and commodity fetishism blinded the people to its common materialist interests. Jesus taught that the meek will be rewarded for their meekness, and while on earth we should render unto Caesar what is Caesar's; Marx explained that meekness as a virtue is a way of preventing actual revolutionary change, and that dividing the world into the spiritual and the materialistic helped keep the people sedate and passive, which plays right into the hands of the Caesars.

*I'm just kidding, I know you don't recognize any of this


**There probably are modern scholars of Christianity who adapt and adopt some of the tools of modern academic discourse; I know too little about academic Christianity.

<Skip if you're not interested in semantics.>
Stating your annoyance about how people use a word and arguing the semantics of the word only contributes towards clogging up the discussion with waffle and painfully detailed point-counterpoint text-walls that everyone loses interest in immediately. I'm going to do the sensible thing and take the meaning of socialism from what the majority of socialists in the world argue for; things like state control being used to counteract the inherent ruthlessness of the free market (i.e. minimum wage, working conditions, rent controls, holidays and working hours), free education, free healthcare (both paid for by contributions from those with means), social housing or money to assist those who cannot work or find themselves out of work... without spending too much time on the close up detail of it, that's roughly what i'll take it to mean and assume you know what i mean (because that's how the word IS used now, like it or not).
<Stop skipping now>

So without getting upset about etymology, I think a reasonable argument could be made for Jesus being a socialist:
- he believed in good will to your neighbour
- he spent time helping and caring for those who were shunned by society and encouraged others to do so too
- he considered greed to be a hindrance to spiritual enlightenment and/or a corrupting influence (easier for a camel to pass through the eye of a needle and all that)
- he healed and tended the sick for free
- he fed the multitude rather than send them to buy food for themselves
- he argued against worshiping false gods (money for example)

If we believe the stories.

I also think that a good argument could be made for Jesus not being a socialist. You haven't made one, but one could be made.

Marx is open to interpretation, so you're going to have to make your point about his quote clearer. I could take it to mean 4 or 5 different and opposing things.

Renewable Energy from Evaporating Water

I think there could be successful applications of this if employed as a power source for extremely-small-scale, possibly autonomous and/or remote, systems.

Don't ever want to cross a street again. Ever

*This* is how they will sell the world on autonomous cars. Everything thinks they are a good driver. They are wrong.

But, if we sell it as "you are a good driver, but look at the crazy stuff other people do, don't you wish they were replaced by rule-following robots?". Hopefully people will go for it.

Brace yourselves – SKYNET's coming, soon

AeroMechanical says...

Absolutely. It's a mistake to make assumptions about what AI will be like. The doomsayers too often attribute human qualities to it. It's like speculating about alien intelligence. It will come in bits an pieces as we understand it more. My own guess is that, not weighed down by long obsolete genetic imperatives and human psychological pathologies, it will most likely be (in its higher form) an extraordinarily capable problem solver and prognosticator. It will lack the human flaws that typically motivate the killer AIs of science fiction. Of course, it will probably have it's own unique flaws. I do think it's wise to be wary of software that has developed beyond our capability to understand it (much as we don't understand the workings of our own consciousness).

Probably my primary concern about robotic weapons comes from a DARPA proposal I read about some time in the past. What they wanted was an autonomous, bird sized UAV. It would contain surveillance equipment and sensors, and be able to share the data it collects through a mesh network established with it's fellows and the commanders as well as receive orders. It would be intelligent enough to find a suitable strategic vantage point and hide itself. From there it would simply observe. With a large enough swarm of these, perhaps many thousands, you could send them into a city at night. They would each also potentially carry a small warhead allowing them to launch themselves at and destroy threats. Once these robots were entrenched, which might only take an hour or two, whoever controls them would effectively rule the city. Even if they were cut off from their command structure, they might still retain enough intelligence to recognize a particular individual, someone in a forbidden area, someone holding a weapon, or someone not brodcasting the right IFF signal, or any number of things. There might be no defense against such a thing (though there probably will be).

To me, that concept is terrifying. It's not huge hulking terminator-like war machines that could be the greatest threat, just flying, self-guiding, intelligent hand grenades. All someone would need is the capability to manufacture them. No raising an army, no speeches or threats, just a factory and a design. It's also not too far fetched to believe this capability might be available in just a matter of a few decades. They'll be easier to build than nuclear weapons, and oh so convenient and easy to deploy.

Um.... anyways, I dunno where I was going with that. Just lots of random pontificating, but because it's technology, it's silly to try to stop it with legislation. It will happen, as ChaosEngine rightly points out, the best course of action is to be on top of it and to understand it.

Brace yourselves – SKYNET's coming, soon

AeroMechanical says...

There will be autonomous or at least semi-autonomous combat robots and there is no stopping it. For one thing, they've already been in use since the early 80's. Cruise missiles are autonomous killer robots. The only difference is that they don't come back when the job is done, but that's a trivial point. More importantly, having a human always in the loop makes current drones massively less effective weapons and giving a potential enemy such a huge opening for that advantage is unwise. You also really can't ban them because they're simply an assembly of extremely useful civilized tools.

That said, she does hit on a very important point though regarding the application of modern drones, which is that they're being used as terror weapons, which we should not be comfortable with. Having drones loiter day in and day out over civilian populated areas is an inexcusable act of cruelty.

Conservative Christian mom attempts to disprove evolution

shinyblurry says...

The ancestry of living beings isn't just traceable through the fossil record. The study of genetics shows us a huge and utterly overwhelming amount of evidence for the common ancestor idea. Common genes can be traced back to show the lineage of different animals and plants and groups of animals and plants.

Homology is a complex subject..it would take awhile to get into. I found a good link that illustrates the argument against it being a proof that macroevolution occured. If you want to take a look we could discuss further:

http://creation.com/does-homology-provide-evidence-of-evolutionary-naturalism

Ring species show that small changes can indeed lead to separate species. Antibiotic resistant bacteria are evolution in progress. You say that just because small changes can be seen it doesn't follow that big changes can evolve but that's stupid. Big changes are just a series of connected little changes.

I guess it depends on who you ask?

Erwin, D.H. (2000) Macroevolution is more than repeated rounds of microevolution. Evol. & Devel. 2:78-84.

the independence of macroevolution is affirmed not only by species selection but also by other processes such as effect sorting among species.

Lieberman, B.S. and Vrba, E.S. (2005) Gould on species selection. in MACROEVOLUTION: Diversity, Disparity, Contingency. E.S. Vrba and N. Eldredge eds. supplement to Paleobiology vol. 31(2) The Paleontological Society, Lawrence, Kansas, USA

Micro- and macroevolution are thus different levels of analysis of the same phenomenon: evolution. Macroevolution cannot solely be reduced to microevolution because it encompasses so many other phenomena: adaptive radiation, for example, cannot be reduced only to natural selection, though natural selection helps bring it about.

Scott, E.C. (2004) Evolution vs. creationism: an introduction. (Westport, Conn: Greenwood Press).

Macroevolution is decoupled from microevolution, and we must envision the process governing its course as being analogous to natural selection but operating at a higher level of organization.

Stanley, S. M. (1975) A theory of evolution above the species level. Proc. Natl. Acad. Sci. (USA) 72: 646-650.

In conclusion, then, macroevolutionary processes are underlain by microevolutionary phenomena and are compatible with microevolutionary theories, but macroevolutionary studies require the formulation of autonomous hypotheses and models (which must be tested using macroevolutionary evidence). In this (epistemologically) very important sense, macroevolution is decoupled from microevolution: macroevolution is an autonomous field of evolutionary study.

Ayala, F.J. (1983) Beyond Darwinism? The Challenge of Macroevolution to the Synthetic Theory of Evolution. reprinted in PHILOSOPHY OF BIOLOGY, M. Ruse ed. p. 118-133.

When discussing organic evolution the only point of agreement seems to be: "It happened." Thereafter, there is little consensus, which at first sight must seem rather odd. -(Simon Conway Morris, [palaeontologist, Department of Earth Sciences, Cambridge University, UK], "Evolution: Bringing Molecules into the Fold," Cell, Vol. 100, pp.1-11, January 7, 2000, p.11)

Nixie: Wearable Camera That Can Fly

newtboy says...

I concede many of your points, and don't understand some others, but it would seem that this

*related=http://videosift.com/video/nano-crazyfly-drone

is pretty damn close to the nixie already, except for the slap bands and the pretty cover. Maybe mount it on a gauntlet? Then it could be magnetically assisted in 'landing' on your wrist.
I know the 'crazyfly' isn't autonomous, but good software could make it remotely computer controlled. Close enough for me.

My_design said:

Yeah, but they are looking for funding, so someone is going to pony up. I watched the video. Most of what they show is a Hubsan FPV quad that you can get through places like Banggood it uses a spreadspectrum 5.4 system to broadcast the video and a 2.4 system for control, but it does not have any autonomous capabilities. Hubsan makes some of the best stuff out there and we work very closely with them. The wrist thing is cludgey, and while it conveys the idea (You can see the needed twist I was talking about), it wont get them anywhere near their presented final design. Wifi would be an option, but it would require a wifi hotspot be built into the quad. I know we aren't talking about components that require a bunch of power, but we are talking about small batteries, so every mV counts. Especially for something that is wearable.
Now the Hexo+ is very much like the Airdog. Both seem very viable and are using existing technologies. My only concern about either is what do they do about object avoidance and low battery response. In either situation you can wind up losing the vehicle or injuring someone. Most higher end quadcopters have the ability to Return To Home (RTH) which is great since the pilot is in a stationary position, but put a pilot on the move and things get weird. If you are out surfing and the quad gets a low battery warning due to either a battery failure or having been waiting for 30 minutes for you to catch a wave, where does it go? It could go back to the take-off position, but if you drifted from there then it will need to calculate that distance and make sure it can get back. Salt water and electronics don't play well together. If you take your quad with you for a ride on a skateboard down the boardwalk, how do you make sure it doesn't hit a light post or a tree while it is zipping after you? You could fly at a higher altitude, but the zoom lens on the camera may not be enough. Hexo+ has a video of the founder riding a skateboard while the quad films. Notice that he stops short of going into the wooded area. I wonder why?
There are issues, but at least in both cases I think they are starting from proven technologies and have footprints that are achievable.
