Comment Not going to happen (Score 1) 866

Personally, I believe it could work - if managed properly (which would not be simple - but what is simple in a complex world?)

I also believe it is not going to happen any time soon, and for a whole different reason.

I think somebody (a Latin author? maybe Horatio?) once said, "I do not love money, but it makes me feel safe."

An universal basic income, to some extent, would make people feel less afraid.

And that would be unfortunate, because so many structures of our civilization are built on fear. (I am sure anyone here could make some example of this.) And significantly reducing the amount of fear in most people's lives would have a dramatic disestablishing effect. So... it is not going to happen any time soon.

However, we tend to forget that civilizations are intrinsically transient - they have been rising and falling for the last 12000 years at least - and this one is not looking good. (My personal opinion - and I may be wrong - is that we jumped the shark sometimes between the 70s and the 80s of last century.) So it is possible that a future civilization, built on different premises, will make it work for good... (The heck, in a few centuries historians will look back to this time of history, and wonder what in hell we were sniffing, smoking, or assuming by any other means!)

Inside the shadowy world of birth tourism at ‘maternity hotels’ - The Washington Post

"In luxury apartment complexes in Southern California and in grand, single-family homes in New York, “maternity hotels” are brimming with pregnant women and cooing newborn babies.

For wealthy foreign women, the facilities offer the promise of a comfortable, worry-free vacation complete with a major perk: a U.S. passport for their newborn."

Maybe they should have a friendly talk with the IRS...

Comment Re:How? (Score 1) 516

IIRC old pal Albert Einstein once said that the most abundant elements in the known universe were Hydrogen and Human Stupidity (and he was _mostly_ sure about Hydrogen!)...

What I find disturbing is, having to live in a society that must rely on collective stupidity to perpetuate itself - maybe I am a closet masochist, but some days I would rather deal with the consequences of a sudden resurgence of common sense! (And it is not impossible, just unlikely - see clam666's post in this thread about how this kind of attitude can spread.)

Thanks for the feedback ;-)

1. I totally agree with you. I am actually putting most of those guidelines into practice, and they work.

2. You are obviously aware that, if _everybody_ eventually shared your (our) point of view, our current economic system (that is driven by consumerism) would collapse in a rather short time. (Eventually it would be replaced by something different, the likes of which I cannot imagine yet; also, the transition phase should be... interesting - like the "interesting times" from the Chinese proverb.)

3. [quote]"You don't need [...] to have a spouse or to have children."[/quote] Same here... However, if _everybody_ eventually shared your (our) point of view, the whole world is going to look a lot like Japan (or China 25 years from now). Somewhere along the way, we forgot that, to survive as a species, we need to raise the next generation, and to do it so that they are able to adapt to changes. Geological sediments are full of those who failed to do that.

4. Unwanted consequences from items (2) and (3) are probably coming anyway, so maybe we should just not care...

High-frequency trading is bad for normal investors, researchers say - Quartz

Also includes some details on how high-volume arbitrage (the actual issue at stake) works.

My quotes:

"Although the term “high-frequency trading” (HFT) is often used loosely to describe trading at high speeds by computers, in this case we mean something specific: high-volume arbitrage activity, which plays on small, temporary differences in price between, say, a security trading both on the New York Stock Exchange and DirectEdge.

[...] By anticipating future NBBO [National Best Bid and Offer price], an HFT algorithm can capitalize on cross-market disparities before they are reflected in the public price quote, in effect jumping ahead of incoming orders to pocket a small but sure prot. Naturally this precipitates an arms race [...]

[...] HFT doesn’t actually make markets more efficient. It’s great for those who practise HFT, but it reduces profits to everyone else, because in those few milliseconds before the NBBO is calculated and disseminated, the high-frequency traders carry out deals at a price that favors them.

In fact, [...] the difference between investor bids (offers to buy) and asks (offers to sell) is wider when arbitrageurs get into the mix, meaning neither sellers nor buyers in the non-HFT world are getting the best price they could."

Comment Prior art :-) (Score 1) 146

If I remember correctly, there was something like that in one of the classic Tom Swift novels - maybe "Tom Swift and His Sky Train; or, Overland Through the Clouds" (1931). It was actually better - Swift's airship would drop from the sky and grab his train car from the rails while running...

Anyone who got the book can confirm?

Submission + - Mental health: NIMH distances itself from DSM-5 (

Big Nemo '60 writes: The world's biggest mental health research institute is abandoning the new version of psychiatry's "bible" – the Diagnostic and Statistical Manual of Mental Disorders, questioning its validity and stating that "patients with mental disorders deserve better". This bombshell comes just weeks before the publication of the fifth revision of the manual, called DSM-5.

On 29 April, Thomas Insel, director of the US National Institute of Mental Health (NIMH), advocated a major shift away from categorising diseases such as bipolar disorder and schizophrenia according to a person's symptoms. Instead, Insel wants mental disorders to be diagnosed more objectively using genetics, brain scans that show abnormal patterns of activity and cognitive testing.

Comment Re:batteries are not rechargable (Score 1) 247

Well, aluminium is also known as "solid electricity", I guess this just gives the expression a new meaning...

I wonder how efficient would be the process of recycling the spent aluminium plates, compared with recharging a conventional battery of comparable power. We should also take logistic costs into account - that is a lot of mass to collect from service stations, recycle, and then redistribute to service stations. I guess you could use electric trucks for that. I also wonder how that would compare with the logistics of fossil fuels distribution.

Having to stop for adding water sounds odd, even if this is an experimental rig. Why not have a water tank and a pump? (OK that could get interesting in winter, I doubt you can add antifreeze to the water that goes into the battery...)

Energy density is what makes this interesting - after all, energy density is the Holy Grail of battery technology for electric cars. 8 kWh/kg are 28800 kJ/kg (if my math is right!), that really seems a lot - according to Wikipedia, energy density for Li-ion batteries is 460 kJ/kg - that is a 60 to 1 ratio! (I still think there is something wrong with my math!) Battery weight should also be taken into account when evaluating overall energy efficiency of such a system - after all, an electric car must also carry around the weight of the battery.

Besides that, this sounds fun. Refuelling would be similar to swapping batteries into a toy car, just much bigger.

Comment Learning "useful" skills (Score 1) 1006

The Connecticut policeman mentions an interesting detail. Apparently, Lanza replaced the magazine of his rifle every time, before entering another room, even if the magazine in the rifle was not empty yet. The policeman suggested that he had learned this trick by playing first person shooters. While this would be difficult to prove, it sounds plausible. Playing FPSs may not have made Lanza a killer, but might have made him a somewhat more effective one.

That said, while I do not condone gratuitous violence in video games (or other entertainment media for that) I do not believe censure would do any good (news media covering this kind of events probably are much more harmful); I also believe that more effective controls over the acquisition and possession of firearms would be appropriate, regardless of these tragic events (the existing rules are way too easy to circumvent), but I do not really believe this would stop a determined psychopath.

While we are at this, I also believe better mental health services should be put in place, also regardless of these events, nevertheless I expect most mass shooters would just "fly under the radar" (I can not find it right now, but someone pointed out that, according to current criteria, most of the mass shooters involved in recent episodes would *not* qualify for compulsory psychiatric treatment *before* they went on a killing spree.)

So... does anything work? Can we "fix" this just by changing some rules? I would say no. Rules cannot fill in for the loss of moral values.

As another poster mentioned, this is society eating itself. Sometimes I really wonder whether it is still redeemable.

Comment Law Enforcement (Score 1) 409

I can not find it right now, but I remember an anecdote by a traveller - maybe Jacques-Yves Costeau? - returning to an island in the Pacific he had visited years before. He was surprised to find a police station, that was not there on his previous visit.

As he remembered the natives being the nicest and most peaceful fellows ever, he asked a police officer "Do you really mean, there is crime here now?" The candid answer was, "Of course sir, there is law enforcement now, there must be crime as well."

So uh, what you're saying is that if you were profiting from the situation, even if everyone and their mom was telling you that you were evil scum, you would spend any amount of money to avoid believing them?

Actually, this sounds like a pretty good definition of "denialism".

Now look, if one or two people tell you that someone is an asshole it might be bias, but if everyone tells you they're an asshole, it's probably true — even if they're talking about you.

Totally agree.
