Vacuum assisted aim

The video itself is a few years old, but it just appeared at Boing Boing, and it's genuinely interesting to see how well a vacuum system for space urination seems to work:

How to send a secret message without sending it

There's a really good article up at Vanity Fair, by a guy who seems to know what he's talking about, trying to correct the many misperceptions about the US PRISM program aspect of the current NSA "scandal". 

He makes a point (after a good technical explanation as to how the NSA works in the email spying business) which I have always thought pretty obvious:
Sure, people could make the argument that this could be the slippery slope to some sort of effort by the government to monitor your porn subscriptions, but . . . really? The N.S.A. is downloading petabytes of data every day with so many anonymizers and protections in place, it is incomprehensible to imagine (and illegal and technologically problematic) that someone would just somehow start surfing through private records. To me, the slippery-slope argument makes as much sense as the N.R.A.’s position that, if we use background checks to keep guns out of the hands of criminals, the United States is on the way to the seizure of weapons. And they make the same silly argument—they think that the government invades their privacy by running those checks.
I was also interested to read of this pretty clever way of passing information without sending an email:
Sometime after 9/11, al-Qaeda members figured out that a great way to transmit information over the Internet was by not transmitting it at all. Instead, a terrorist would open an account with a free service like Hotmail or Google, write an e-mail, and rather than sending it or even writing in the address of a recipient, would store it in a “draft” folder. Then, through other means such as a satellite phone or another e-mail account, a coded message would be sent to the planned recipient telling him the account name and the password. The recipient would know to open the account, check the draft file, and then delete the account. Once the N.S.A. knew through other means of the existence of the message, it would gain access to the temporary account through a court-issued subpoena to the company, read the secret message, and watch what happened. By 2010, though, the terrorists figured out this wasn’t working anymore and changed tactics.

The good and the bad

Pope Pius XII, Hitler’s pawn? | TLS

This reads as a pretty even handed review of 2 new biographies of Eugenio Pacelli, who was Pope Pius XII (the World War 2 Pope).  It concentrates more on what he did in the lead up to the war, rather than during it.    For example:

In early 1933, Hitler, now Chancellor, but not yet dictator, surprised Pacelli by putting out feelers for a Reichskonkordat. Hitler was offering guarantees assuring Catholic rights to religious practice in exchange for the Church’s withdrawal from every kind of social and political action, assembly and association – including newspapers, scouting groups and women’s associations. As a sweetener, Hitler offered extra educational funding for Catholic schools – for buildings, places and teachers. But the condition laid down by Hitler was that the Centre Party should vote for the infamous “Enabling Bill”, awarding him dictatorial powers, followed by the Party’s voluntary disestablishment. Ventresca concludes that the Reichskonkordat left German Catholics with no “meaningful electoral opposition to the Nazis”, while the “benefits and vaunted diplomatic entente [of the Reichskonkordat] with the German state were neither clear nor certain”. 

Recent historiography of the behaviour of the professions, Churches and judiciary from 1933 onwards in Germany, suggests that Pacelli’s dealings with Hitler had devastating consequences. The role of the judges, scientists, academics, who individually and collectively did deals with, and took benefits from, Hitler, while remaining aloof from his vicious ideology, has been characterized as that of the Mitläufer: the fellow traveller. It could be argued that the Mitläufer did more damage than card-carrying Nazi members of the churches and professions. There were indeed several Nazi Catholic prelates, known as the “Brown Bishops”, who were figures of contempt among the faithful. But the consequence of “fellow-travelling” by figures of respect and distinction, and the institutions they represented, was to demoralize potential opposition, scandalize the young, and dignify Hitler at home and abroad. Pacelli was the Führer’s ideal prelate, and future Pope, because his diplomatic accommodations suited, albeit unintentionally, the dictator’s long-term purposes.

Writing in the Vatican newspaper L’Osservatore Romano, Pacelli declared the Reichskonkordat a triumph for the Code of Canon Law. The subtext was that Hitler had accepted the imposition of the new Code on German Catholics, hence the shift of governing authority from the local Church to the Vatican. For Hitler, speaking in cabinet, the treaty meant the “recognition of the nationalist German state” by the Vatican, as well as withdrawal of the Church from political organizations, and the disbanding of the Centre Party. Finally, and ominously, Hitler declared that the treaty created a “sense of confidence” that would be “especially significant in the urgent struggle against international Jewry”. Pacelli was not anti-Semitic in the Nazi sense; yet he had accepted on behalf of Pius XI educational benefits from a regime that was simultaneously depriving Jews of corresponding rights and resources. The circumstance signalled an acquiescence in Hitler’s anti-Semitic policies at the origins of the persecution of Jews in Germany.
I didn't realise that Pope Paul VI had "launched the cause for his beatification".   There does seem to be a bit of an unseemly haste, if you ask me, for recent Popes to want to make their predecessors saints.   But I see from Wikipedia that the recently retired Benedict was originally reluctant:
Benedict XVI had advocated waiting until the archives from Pius XII's papacy were opened to researchers in 2014.[1][2] A selection, the ADSS, edited by a multinational team of Jesuits, was published between 1965 and 1981. Benedict XVI changed his mind and declared Pius XII Venerable on December 19, 2009, based on the recommendation of the committee.[1] Pope John Paul II, Benedict XVI's predecessor, was declared Venerable on the same day.
I expect waiting for the full archives to be read would be worthwhile.   

Grogonomics recommended

I've been forgetting to note how much I enjoy Greg Jericho writing on economics at The Guardian.

I particularly liked his post this week taking apart the Rupert Murdoch twitter summary about Australia's current economic position.   Rupert's view, by strange coincidence [/sarc] happens to be the ABCIG* collective view as well.

It also appears to be based on lack of knowledge of some actual figures, but is repeated to Murdoch in the circles he moves in so often, he clearly has started to believe it.

Speaking of the Catallaxy economists, as Jericho notes in his most recent post, the stagflation fear mongering which turned up on the ABC (which, by wide yet nonsensical acclaim at Catallaxy, needs to be sold immediately under a Coalition government because, I guess, not enough wrong predictions by their favoured economists have been appearing) and at Andrew Bolt's show (the collective in operation) is at its two year anniversary of non fulfilment.  Congratulations.

*  the Australian, Andrew Bolt, Catallaxy, IPA and Gina Rinehart collective.   It used to be just the ABC collective, but Gina and the IPA well and truly deserves their positions as well.  In fact, its become so bad, Andrew Bolt would only have about 1/3 of the content he currently runs on his blog if it were not for Catallaxy.

Fascists do the strangest things

BBC News - A gay island community created by Italy's Fascists

A somewhat interesting story here of an island exile which Mussolini set up in the 1930's for homosexual men.

The way fascist Italy dealt with them was a step up from Germany, I suppose, but still:  
No discriminatory laws were passed. But a climate was created in which open manifestations of homosexuality could be vigorously suppressed.

And one particular police prefect in the Sicilian city of Catania took full advantage of the official mood.
"We notice that many public dances, beaches and places in the mountains receive many of these sick men, and that youngsters from all social classes look for their company," he wrote. 

He said he was determined to halt this "spreading of degeneration" in his city "or at least contain such a sexual aberration that offends morality and that is disastrous to public health and the improvement of the race".

He went on: "This evil needs to be attacked and burned at its core."

So in 1938 around 45 men believed to be homosexuals in Catania were rounded up and consigned to internal exile.
They were locked up in dormitories at 8pm (under police supervision, it says), and had no electricity or running water, but apart from that, it appears the days were pretty relaxed:
"In those days if you were a femminella [a slang Italian word for a gay man] you couldn't even leave your home, or make yourself noticed - the police would arrest you," he said of his home town near Naples.
"On the island, on the other hand, we would celebrate our Saint's days or the arrival of someone new... We did theatre, and we could dress as women there and no-one would say anything."
And he said that of course, there was romance, and even fights over lovers.
Then the war broke out, and they had to go back home to "a kind of house arrest", and some were disappointed to leave.It does sound like most sent to the island were effeminate, although there is reference to a seminarian who somehow was exiled there.

The article ends on a point I hadn't realised about the state of gay politics in Italy today:
There is still no real social stigma attached to homophobia in Italy, Scalfarotto says, and the state doesn't extend legal rights of any kind to gay or lesbian couples.
The influence of the Church, I assume?   One thing I have never understood, though, is why the Spanish Latin countries seem to have adapted to gay relationships very quickly, given that the macho culture reputation and Catholic influence.   Why have they changed very quickly, yet Italy is conservative on the matter?  I also don't really understand the strength of the anti gay marriage sentiment in France:  a country I had assumed had little Catholic influence.  I know there are other elements in the protests there, but still... 

Is this why dogs have sometimes detected it?

Scent of melanoma: New research may lead to early non-invasive detection and diagnosis

It's only tests in the lab so far, but still:
The researchers used an absorbent device to collect from air in closed containers containing the various types of cells. Then, gas chromatography-mass spectrometry techniques were used to analyze the compounds and identified different profiles of VOCs emitting from melanoma cells relative to normal cells.

Both the types and concentrations of chemicals were affected. Melanoma cells produced certain compounds not detected in VOCs from normal melanocytes and also more or less of other chemicals. Further, the different types of melanoma cells could be distinguished from one another.

Noting that translation of these results into the clinical diagnostic realm would require a reliable and portable sensor device, the researchers went on to examine VOCs from normal melanocytes and melanoma cells using a previously described nano-sensor.

Constructed of nano-sized carbon tubes coated with strands of DNA, the tiny sensors can be bioengineered to recognize a wide variety of targets, including specific odor molecules. The nano-sensor was able to distinguish differences in VOCs from normal and several different types of melanoma cells.

Another 4 billion?

World population could be nearly 11 billion by 2100, research shows

African fertility is not slowing at the expected rate, and hence:
The current is about 1.1 billion and it is now expected to reach 4.2 billion, nearly a fourfold increase, by 2100.
That's pretty remarkable.  

The boss divorces

That's interesting.  Rupert Murdoch is getting divorced from his Chinese wife.

I've been puzzled by his swings on issues - he was an early enthusiast on climate change, and I suspected her influence.   (She is said to have introduced him to a younger crowd.)    Of course, he now rarely mentions it and has no regrets about running media outlets which are an absolute disgrace in their coverage against climate change being real, and I wonder how this sits with her.   His politics lately has been swinging harder Right, it seems to me.  

I therefore wonder if he will soon be worse in that regard. 

One other thing:  I find it truly remarkable that Britain still has "page 3 girls" running his Sun newspaper.  Earlier this year, it was noted that maybe Rupert was considering stopping it.

Obviously, his wife either had no interest in the topic, or had not been able to influence him on it for a decade or so before this year.

On the menu today...

Michelle Grattan's summary of the whole issue of Julia Gillard and women is very good.

I have a few comments:

*  the two Ruddite MP's who were happy to go on TV and say they didn't think it was a good idea for Gillard to make the comments she did in her speech to the women's group are complete idiots who obviously have no concern at all for the devastation that a disunited party will cause at an election.   I doubt that Rudd was behind this - his performance on TV yesterday attacking the Liberals on "menu-gate" was good:  he clearly has some stupid supporters, however. 

*  when a politician's first response to an embarrassing document is "I don't recall seeing it", it is usually code for "I saw it but with any luck I'll get away with this if I use this phrase."    It would appear both Brough and Hockey used the formula.   (Hockey definitely did; Brough seemingly has been kept away from the cameras for fear he will stuff up his own defence.)    Given that it appears from the first reports about this late yesterday morning that Brough knew all about how it was (allegedly) created but not distributed, the late arrival of the exculpatory email from the restaurant owner was suspicious too.    Sorry, but given Brough being shown up as a liar before, I think it highly likely he will soon be shown to be a liar again.    If so, this will do more harm than the menu itself.

*  scepticism of the restaurant owner's explanation was evident on breakfast TV this morning, with a reporter outside the restaurant (will this be good or bad for their business, I wonder?)  saying that staff had hinted the menu had been on the tables.   This is all silly business, but it will be fun to see what develops today.

*  there is too much concentration on the messaging rather than the message as far as Gillard is concerned.  Labor supporters like Jane Caro and Eva Cox should just shut up if they want to help.

*  Joe Hockey seems a bit of an unexpected wuss for complaining about Gillard apparently referring to him as a fat man.  First of all, no one remembers that, and secondly, he had gastric by-pass surgery to lose weight, for goodness sake.   If Gillard helped encourage him to a healthy weight, stop whining about it.

A good thing for the government to question

Who really pays for designer vaginas?
Increasing numbers of Australian women are asking their doctors for a designer vagina. So many, in fact, that the government is reviewing whether such surgery should be publicly-funded via Medicare.

Over the last ten years, claims through the medical benefit scheme (MBS) for labioplasty have increased from 200 to over 1,500 per year. The resulting cost, rising from $40,000 to $740,000 annually, has led to a government review questioning the procedure.
As the article says,  there is virtually no doubt at all that the demand for this surgery is driven by a combination of the ubiquity of pornography due to the internet, and the fashion for pubic hair removal.   Perhaps a government advertising campaign against both is called for?  (Well, it would be interesting to sit in on the ad agencies workshopping such a campaign, at least.)

Saletan on the NSA kerfuffle

The NSA’s phone-call database: A defense of mass surveillance. - Slate Magazine

I find it hard getting excited about this issue - I thought all sensible people just assumed that no electronic communication was free from secret US (and probably other countries) access.   

But William Saletan has a column explaining some of the detail of the current story that is exciting both the Left and Right in the US, for very different reasons. 

M'eh.   Still seems no big deal to me.

Free advice to Kevin Rudd and Julia Gillard

Dear Kevin & Julia,

If you really, really want to help Labor, and (for Kevin) preserve the possibility of returning to the leadership in the future, here's what you could do:

1.  Kevin:  start referring to the Prime Minister as "Julia", on TV, not all the time, but at least once or twice between your insistence on referring to her as "the Prime Minister" (as if her actual name remains poison to you.)

2.  Kevin and Julia:  stage a very public reconciliation meeting for the cameras (perhaps with a couple of other Rudd "enemies" in the background) at which Kevin refers to "Julia" at the key point where he explains that you are reconciled, and Kevin makes it clear that he will co-operate in all respects with campaigning and media appearances so as to not give the impression that he is still competing for the leadership.

3.  Julia:  at the reconciliation meeting, explain that Kevin will return to Cabinet  in the event of the return of the Labor government.  Use the reasoning that it's obviously too late to fit him back in now, and returned Prime Ministers typically do re-shuffle things a bit.  Talk him up as obviously a person who the public wants to see in a more prominent role in government, and you are willing to accommodate this.

Is it beyond the realm of possibility that such an obviously useful tactic could be achieved by Labor?

Colebatch on the dollar, again

Blame it on the dollar, but can we rein it in?

My favourite economics commentator emphasises in this column how much the high Australian dollar alone has been responsible for many business's high operating costs:
Between 2010 and 2013, the IMF estimates, we and our producers have been paying a staggering 55per cent more for goods and services than our US counterparts.

Our costs against the US and the world have doubled in a decade. Not all of that is due to the dollar. Wages and prices have kept rising at vaguely normal pace here, while barely growing at all in Europe, Japan and the US. But the dollar's rise is the main reason.

Since 2010 its average value has been almost 50 per cent higher than it was in the years from 1985 to 2005. Whether you are Ford, BHP, the University of Melbourne or a Wimmera wheat grower, that is a crushing competitive burden.

Relief has come in recent weeks. As the US recovery gains strength and our economy weakens, the dollar has fallen 10 per cent since April 12, when it stood at a 28-year high on the Reserve's index.
But it also sank below parity for some weeks in 2010, 2011 and 2012, only to return again. And it needs to fall much more before many Australian producers will feel confident to invest and expand.

Back to that Lee Smolin book...

Further to my recent post regarding physicist Lee Smolin's new book, I see that someone at Backreaction has put up a link to a copy of its review in Nature.   It makes the argument in the book a little bit clearer.

Something to come back to

At about 70 pages, I don't have time to read this essay I found at arXiv on physics, free will and Turing, but I will come back to it.

Reviewing Darwin and Johnson

Essay Book Reviews - Irish Book Reviews - Dublin Review of Books

I mentioned late last year that there is a short book out by Paul Johnson about Charles Darwin.

This lengthy review is of the kind that seems to make it unnecessary to read the book.  I like this kind of review...

Hope for my brain

Nuclear bomb tests reveal brain regeneration in humans - health - 07 June 2013 - New Scientist

Nuclear bomb tests carried out during the cold war have had an unexpected benefit.

A radioactive carbon isotope expelled by the blasts has been used to date the age of adult human brain cells, providing the first definitive evidence that we generate new brain cells throughout our lives. The study also provides the first model of the dynamics of the process, showing that the regeneration of neurons does not drop off with age as sharply as expected.
Very clever work.

Spices considered, and nutmeg revisited

This seems to be the second series on SBS I've seen in the last couple of years devoted to spices, but I have been enjoying Spice Trip.  Last night they were on Grenada, a country you rarely see on travel shows, looking at nutmeg and mace.

Curiously, the male co-host, a London chef with a name (Stevie!), voice and manner which I thought indicated he was gay, last night noted that he has one child and another on the way.  (He has a wife and two sons, I see.  Maybe the English really are the easiest nationality to mistake as gay.)    This came up in the context of the alleged aphrodisiac qualities of nutmeg - people from Grenada talk a lot, it seems, about how a meal full of nutmeg will assuredly make you "horny". 

My decreasing number of long term readers will recall my interest in nutmeg because of Uncle Scrooge having an addiction to nutmeg tea, which turned out to be kind of unfortunate because you can indeed get high (although not pleasantly so, apparently) from consuming too much of the spice.    And yes, this did get mentioned on the show last night, with a warning that you should consume no more than 5 g a day, and (if I recall correctly) more than 15 g might kill you (!).   I must now weigh a nutmeg nut to check its weight.

Anyhow, I see the whole episode is on DailyMotion, if you are interested:


E4 Spice Trip - Nutmeg - Grenada by zodiacza

What was I saying about Christopher Pyne earlier this week?

Christopher Pyne's strained relationship with the truth* continues to be operating at crisis level, and I don't think they're ever going to be reconciled again:  

Lateline - 06/06/2013: Election countdown: CHRISTOPHER PYNE, MANAGER OF OPP. BUSINESS: I understand from sources within the Labor Party that Julia Gillard demanded that she'd also be able to appear.

TOM IGGULDEN: That was denied by both the Prime Minister's office and the ABC.

LEIGH SALES, 7.30 PRESENTER: For the record, I can confirm that the Prime Minister did none of those things.

TOM IGGULDEN: Mr Pyne claimed the interview had already been recorded.

CHRISTOPHER PYNE: And in her interview, I'm told from my Labor sources that she has demanded that Mr Rudd rule out a challenge to her leadership.

TOM IGGULDEN: In fact, that question was put by Leigh Sales.
* heard at their counselling session:  "It's like he doesn't know me anymore.  I ring, and the next day he claims he can't remember".
