Floods and economics considered

The recent monsoonal rainfall event in North Queensland has certainly been devastating to the cattle industry:
The latest estimate is that 500,000 cattle have perished in the floods. That is a death toll of biblical proportions.

At a value of $1000 a head, that’s $500 million worth of livestock gone.

But this is about more than the dollars.

Many of these cattle have been kept alive by desperate farmers who have battled seven years of drought — drought that continues despite one dump of rain. They have spent thousands of dollars on fodder they can no longer remember once growing themselves.

The toll on those farmers is enormous. Unthinkable even.

Agforce chief executive Michael Guerin rightly described it as a “massive humanitarian crisis”.
“The loss of hundreds of thousands of cattle after five, six, seven years of drought is a debilitating blow, not just to individual farmers, but to rural communities,” said Mr Guerin, whose organisation is the state farming association.
Looking to the future, the CSIRO openly admits that it is very difficult to be sure of the long term rainfall effects of climate change in Australia.   I thought they generally expected North Australia to get wetter, but Southern Australia to dry out, but the Climate Change in Australia website says this about the Monsoonal North:
Providing confident rainfall projections for the Monsoonal North cluster is difficult because global climate models offer diverse results, and models have shortcomings in resolving some tropical processes. Natural climate variability is projected to remain the major driver of rainfall changes in the next few decades.

By late in the century, rainfall projections have low confidence. Potential summer rainfall changes are approximately -15 to +10 per cent under an intermediate emission scenario (RCP4.5) and approximately -25 to +20 per cent under a high scenario (RCP8.5). Per cent changes are much larger in winter in some models, but these changes are less reliable because average winter rainfall is very low.

Impact assessment in this region should consider the risk of both a drier and wetter climate.
They do, however, expect extreme rainfall events to increase:
Despite uncertainty in future projections of total rainfall for the Monsoonal North cluster, an understanding of the physical processes that cause extreme rainfall, coupled with modelled projections, indicate with high confidence a future increase in the intensity of extreme rainfall events. However, the magnitude of the increases cannot be confidently projected.

Drought will continue to be a feature of the regional climate variability, but projected changes are uncertain.

In terms of risk, let me muse this:   the problem is surely with the frequency with which extremes occur - if a flood of this kind that formerly happened only once in (say) 100 - 300 years starts to occur 2 to 3 times within a lifetime (say, every 20 - 30 years), you can readily imagine that certain agricultural enterprises will just abandon that form of land use due to the "wipeouts" coming at such a rate that it becomes too much of a risk, even if you can get some good years out of it in the intervening years.

This is why I am completely sceptical of economic predictions of the effect of climate change:  even if you make guesses on whether certain regions become generally wetter or drier (and therefore more or less potentially agriculturally productive), the confounding factor is in the details of the frequency of wet or dry disasters within the big picture.  

There's no way of confidently predicting that at the moment, so how can you deal with it in economic models?

Mars One on the way out

I was dismissing the Mars One project as an obvious bit of PR flim flam back in 2015, and I see that it is finally looking as if it is on its last legs.  Although there is a mystery investor who may be stepping in, apparently.

I wouldn't put it past being Peter Theil - he's nutty and rich enough.

Singapore holiday - Part 1

Well, let's get going with a post about my recent Christmas holiday to Singapore, with side trip to Malacca.

I hadn't been to Singapore for about 17 years, and although I have probably been there three times before, they were all fairly brief stays.  Maybe 2 to 3 nights each?

It has changed a lot since the 1980's when I first went there.

This time, we stayed down in the Chinatown area, which, stupidly, I don't think I had ever wandered into before.  To be perfectly honest, in previous trips, I find it hard remembering going anywhere much further afield than Orchard Road and the area around Raffles.  (I did actually spend one night at the famous hotel, alone, in the 1980's, no doubt before the last couple of renovations.  The place is yet again under refurbishment, to re-open this year.) 

Anyhow, given the extent of the MRT system now, staying in any of the districts is convenient, but the streets of Chinatown area are pretty attractive in that old Asian terrace house sort of way:

 



That large apartment building you can see - here's a better view from our hotel window (the Amara Hotel, which I highly recommend.)


Singapore loves spectacular and interesting architecture, of course, and that rooftop garden spanning 6 tower blocks reminded me of a poor (OK, modest income) man's Marina Bay Sands Hotel rooftop.

I went for a walk towards that building and found out, completely fortuitously, that you can go to the end block on the left and get a ticket from a tiny,  hidden office to go to the rooftop garden decks for all of $5 (I think).   So the next day, I did exactly that, and took some panorama shots which will look a bit crappy here, but good if not compressed to fit inside Blogger.  (You can click to make them bigger, though.)








The rooftop gardens are nicely kept and quiet - there is no pool (only a imitation one!)


and the area is really for the residents, as this not exactly promoted as a tourist attraction.  The views are very spectacular, though, and I was very happy with the serendipitous discovery that I could get up there:










The thing I had forgotten about Singapore is that, although it's small and now super easy to get around, the reason I had been there a few times before and never got around to doing the tourist hits like the zoo and Sentosa Island is because the ridiculous humidity means you just want to be indoors between 10 am and 6pm, and getting inside good airconditioning makes it difficult to go outside again.

Fortunately, the biggest tourist attraction now - the Gardens by the Bay, behind the Marina Bay Sands Hotel - has air-conditioned conservatories which are spectacular and, of course, very popular:












I didn't realise that Singapore did Christmas with an intensity which I suspect is only surpassed by European countries.  In the gardens outside the conservatories:





If you're wondering what the stuff in the air is, it's fake snow (sort of soap foam, I think) that gets blown out at the end of the Christmas music and light show.   People find it exciting, making fake snow in 25 degrees and high humidity - who am I to question the logic of it!


And you know what - that was the only big tourist attraction we got to!   Still haven't been to the zoo or Sentosa.  But we did see more spectacular architecture:



I love the way so many buildings incorporate plants - including this hotel, near ours in Chinatown, nearly completely vine covered.

And, of course, there is the spectacular Marina Bay Sands Hotel with fancy shopping centre below it:

 









I was interested to read about the engineering of the building - the infinity pools on the top deck presented a special challenge:

Keeping an edge straight and level is hard enough, but let’s make it harder by putting the pools on top of three tall towers. We know a pool this size is going to be heavy. Yes, we know the towers are going to sink over time as their foundation cause the clayey earth and landfill to shift. Each will subside at a different rate, and each tower may rotate. You can’t expect the ground under each tower to be of even density and hardness. Yes, the wind will cause the maximum deflection at the top of the towers, also differently for each tower. But you’re engineers. You’ll figure something out. That infinity pool must work.

The weight of the pool was going to be staggering. When full, the three pools held 380,000 gallons (1.44 million liters) of water. Add to that the 422,000 pounds (191,000 kgs) of stainless steel that formed the bulk of the pool structure, and then the 250.000 ceramic tiles cemented on…

Support of the stationary weight was one thing, and keeping the whole deal flat was another. Arup, the firm hired to complete structural analysis of the towers, could handle stationary weight. Since they were roof top pools, a specialist was brought in: Natare Corp., a pool manufacturer on the other side of the world in Indiana. Natare devised a system of hydraulic jacks, 500 of them, that would level the pool no matter the movement of the towers. Though the lateral movement of the towers could be almost 20 in, the jacks were able to keep the wall to within 4 mm over the entire 478 ft length (146 m).


That ride in the shopping centre looked a bit too "Las Vegas" to me, but its fun to watch the swirling water from above anyway.    The public areas outside of the hotel and shopping centre are very attractive, though:

 

The Cathedral of the Good Shepherd is one of the few old buildings I photographed - mainly because I really don't think it looks particularly Catholic in architectural design.   (Looks more like what I imagine would be American Episcopal.)   But no, I see from its website that it's always been Catholic.    It was full to overflowing on Christmas Day, and I stood outside in the still withering humidity at 6pm listening to a very cloying American style sermon, as it happens.  I don't know whether the Singaporean Church stands in terms of the current slow moving crisis between modernisers and conservatives - it would be interesting to know.    You would think the Chinese in it would not be eager to normalise gay relationships - but then again, I know of a gay chinese couple (from Singapore originally) in Australia who have been making babies via surrogacy - so who knows.




Oh, here's another old-ish building - the Buddha Tooth Relic Temple in Chinatown [wait a minute - no it's not - I didn't read carefully about it, obviously - it was only started to be built in 2005! I thought I had read it was an old, refurbished temple, but apparently not.]   Anyway, it which has some massive works going on beside it at the moment, detracting a bit from the aesthetics.

We stopped during a rather popular looking service was going on:

 


Singapore seems keen to promote itself as clean and green - certainly, I was on the look out for the otters that are now famous, but I never spotted them.  I did see movement in the bushes beside the water at Gardens by the Bay, and thought it might be one, but it turned out to be a monitor lizard instead: 



The cutest wild animal I got to see was a squirrel:


I had never known they were on Singapore, although I had read about an Asian squirrel colony that had set itself up in Perth some years.

There is much more to be said about Singapore and how much I like it, despite the heat.   Here's a list of various thoughts:

*  on the downside, apart from window shopping, it really is hard to find anything free to do that is in airconditioned comfort.  I think every single art gallery and museum has an entry fee:  the Singaporean government seem to have no concept of completely funding such facilities, and despite its riches, moneyed Singaporean families don't seem to have spent their money this way either.  Anyway, it still means there is much for me to see.

*  I'm not entirely sold on it being that great a place to eat - I mean, I do tend to worry about the degree of refrigeration used in the cheaper hawker centre outlets, which are also routinely too hot most of the day to be comfortable;  and just before I went on this holiday, a Singaporean couple (not the gay guys mentioned above) recommended I eat in Tangs Department store if I wanted cheap, good food that would be safe to eat.  (I did, and it was good.)   Hotel food tends to be great, of course, and you can do OK in food court outlets in terms of price too.   But overall,  I find Japan is the best country to swoon over food, and never worry about its safety.

* It seems to be that, in broad terms, Chinese Singaporeans are always cheery and good to deal with;  Indian Singaporeans can be OK, but are sometimes grumpy, and Malayas working there are often not particularly cheery at all.   Does this just reflect their general economic standing in the country?

* There are an amazing amount of Australian produce in Singaporean supermarkets now.   The country imports 90% of its food - although I was reading the government is trying to increase self sufficiency in some things.   I think it takes half of its water from Johor as well, although I saw something about a desalination plant on a Youtube video as well.  

*  Tiger Beer is still a good, standard beer.   Craft beer seems not to have had the same impact there yet as in other countries.

*  The MRT is great, although it could do with more ticketing machines in most stations.  

*  Singapore has heated up much more rapidly than the rest of the world in recent decades, but that is acknowledged as being in large part due to the massive urban heat island effect of the place":
The island is heating up twice as fast as the rest of the world - at 0.25 degrees Celsius per decade - according to the Meteorological Service Singapore (MSS). It is almost 1 deg C hotter today than in the 1950s.
 But there is no scepticism at all to be found in Singaporean government websites or media about climate change and the potential threat from it.  In fact, there is a video shown at the end of one of the Gardens by the Bay conservatories which is full of warnings about climate change and the need to address it - and I found that the largely Asian audience was paying close attention to it, too.

Climate change scepticism is a mugs game for American Right wing players and their Australian and English sycophants, primarily.  

Apart from the humidity, I thought it very noticeable that Singapore doesn't seem to have breezes, despite being surrounded by water.  Not sure why that would be, but I see someone else on Reddit saying the same, so it's just not me.

*  Channel News Asia is very good for local Asian news and stories.  There was one about a popular young Iman in Indonesia who is very influential via social media (and he is a convert from Catholicism!)  I must track that down, it was very interesting.


Overall, given that I like stylish urban development, eye popping architecture, fantastic infrastructure, a distinctly pro-environment sentiment about the place, and a mix of cultures that hardly spend any time fighting each other - I really like it.   As someone wrote somewhere, it does have a Disneyland vibe - lets build a new city from the ground up and see how cool we can make it look and work. 

I want to visit again.

I will do a separate post about the side trip to Malacca: this one is long enough.

Push and shove at Tim's place

Tim Wilson's not-very-merry band of "don't touch my government refund of tax I didn't pay" retirees are getting pushy:
Margaret Chuck, 63, was the lone speaker in favour of Labor's policy and was repeatedly booed by the crowd during her presentation.

"This is not money these people have earned. This money comes out of other taxpayers' pockets in such a large amount that it would cover the funding of public schools all across Australia," she said to groans from the audience....

....one man..interrupted the beginning of the Chatswood session by repeatedly yelling "this process is a sham" and "this process is a scam".

The man was forcibly removed by other attendees - during which he tripped and fell over, prompting the crowd to cheer and clap. Asked if there was a security presence, Mr Wilson said: "No, because we don't normally have this childish behaviour."

Bad judgement continues

I've noted before that Sinclair Davidson has a solid history of bad (and self serving, for a libertarian) calls on Royal Commissions, and I see he is still at it:
But, to his credit, Ken Henry spoke truth to power when he appeared at the Banking Royal Commission late last year. Yes, he was arrogant – treating the Commission with the contempt that it deserved being as it was a political hit job by the Labor and National parties. 
I do perversely wish the Coalition would pay more attention to him and his eccentric priorities, as it would ensure their demise is deeper and longer.

Astronomer likes to speculate

Abraham Loeb was the key guy suggesting that the recent asteroid Oumuamua was possibly an alien probe, and he like to think science fiction-y thoughts generally, it seems from this Scientific American piece he wrote:
Meeting a piece of advanced technological equipment developed by an extraterrestrial intelligence might resemble an imaginary encounter of ancient cave people with a modern cell phone. At first, they would interpret it as a shiny rock, not recognizing it as a communication device. The same thing might have happened in reaction to the first detection of an interstellar visitor to the solar system, ‘Oumuamua, which showed six peculiar properties but was nevertheless interpreted as a rock by mainstream astronomers.

Because it would likely be relatively small, most advanced equipment could only be recognized in the darkness of space when it comes close enough to our nearest lamppost, the sun. We can search for technological “keys” under this lamppost, but most of them will stay unnoticed if they pass far away. More fundamentally, one may wonder whether we are able to recognize technologies that were not already developed by us. After all, these technologies might feature subtle purposes—like the cell phone communication signals that a cave person would miss.
He then talks a bit about directed panspermia - the idea that Earth was seeded for life deliberately by alien probes.

Have I ever said this out loud before? - I have long imagined a science fiction comedy starting with a scene in which a UFO lands on a barren Earth for an alien toilet break, and that's how life gets started here.

The big double standard continues

This is topical - Trump talked about stopping HIV transmission in his State of the Union speech (something Conservatives commentary has made no mention of, as far as I have seen - no doubt because it hardly accords with their priorities).   Amusingly, I heard someone say that this idea appealed to Trump because he had so much feared catching it himself from his random sexual encounters in the AIDS heyday.   Sounds a very likely explanation.

Anyway, clearly a crucial tactic for this will be to increase use of PrEP, which allows users to greatly reduce any chance of catching it even with unsafe sex.

But, as I have written before, people do question the tactic if it's going to vastly increase the risk of other STDs spreading through the community.   This should be a particular concern when drug resistant strains of things like gonorrhoea are starting to really be a worry. This is the topic of an article in the New England Journal of Medicine, discussed here.

Generally speaking, it argues that doctors should not worry about the "risk compensation" rise of unsafe sex amongst those on PrEP.   But look at the reason given:

"PrEP does not protect against non-HIV sexually transmitted infections, but concerns about risk compensation do not justify withholding PrEP," said lead author Julia Marcus, Assistant Professor of Population Medicine at the Harvard Pilgrim Health Care Institute and Harvard Medical School. "According to the World Health Organization, is not only the absence of disease, but a holistic state of physical, emotional, mental, and social well-being in relation to sexuality. By enabling condomless sex with less fear of HIV transmission, PrEP has the potential to facilitate the intimacy and pleasure that can enhance sexual well-being for many people."

As the authors note, however, previous studies have suggested that clinicians may discount the importance of the psychological aspects of sexual health.

Look, the aspect of this that seems to be a case of self induced blindness when it comes  to considering gay folk is this:    no one is at risk of catching HIV if they are in a monogamous relationship with a HIV negative person.    But now the argument is that it's crucial to gay men's psychological sexual health to be able to have casual sex with men without a condom.

It is surely a clear case of a double standard here:    a straight man who picks up a woman at a club and has unprotected sex with her that night that results in pregnancy or an STD is going to be thought of at least as someone who made a mistake and let his libido override his common sense.

A straight man who for years goes out regularly and keeps sleeping with women he's just met without a condom is going to be thought of as really pretty dumb, and no one is going to be surprised if he catches a STD or ends up an unexpectedly father.

Surely doctors or friends knowing that's how he's living such a lifestyle are going to say "look, we know condoms don't feel great, but they are pretty reliable and it's not as if you are going to be using them the rest of your life.   If you get a proper girlfriend who you trust as monogamous, and you are too, and that she's using reliable contraception, then you can pretty safely drop the condoms."

How much freaking concern is a friend or doctor of such a straight young man going to have that telling him to use a condom is going to hurt his psychological sexual health?   I think we all know the answer - none whatsoever.

But with gay men, apparently they cannot be psychologically happy if they can't have condomless sex at any stage of their life in any circumstances.

I cannot get over the feeling that PrEP's widespread use is a form of too much indulgence of hedonism, and for just one sector of the community. 

Saletan on the State of the Union

Seems to me that the State of the Union addresses from any US President are weird bits of self serving, insincere theatre, and it's a bit hard to understand why more commentators don't just say that instead of poring over every detail.

I suppose that with a person as dumb, changeable and narcissistic as Trump, the speech might be worth paying attention to if it gives any indication of which way the wind blows with him:  but the problem is, everyone knows any view he holds is disposable and not based on any consistent or principled belief.

It's also gobsmacking that anyone, let alone an Australian, can view Trump as giving a good speech of any kind.   His voice, his mannerisms, his mugging very reminiscent of a Mussolini at times, all override content anyway.

But in any case, here's Saletan, one of the best critics on Trump's dangerous nature, discussing the authoritarian aspects of the speech:

The Alarming Message in Trump’s State of the Union

 The president’s speech wasn’t dull. It was dangerous.

About the North magnetic pole

About time I noted the news about the wandering north magnetic pole:  I see that Vox has a good summary:

The locations of magnetic north and south have always been moving targets. Because of that, NOAA and its partners in the UK release an updated magnetic model of the Earth every five years. That way, navigation systems that use magnetic compasses, like those used by airplanes, can be more accurate and correct for the difference between the magnetic poles and the geographic ones.

The next update wasn’t supposed to happen until the end of 2019. But magnetic north has been moving at a rate of 31 miles a year since the last update in 2015 — faster than usual. 

“The pole moved maybe about 1,000 kilometers [621 miles] between 1900 and 1990, and it’s also moved about 1,000 kilometers between the late 1990s and today, so it’s really sped up,” geomagnetic modeler William Brown explained to The Verge.

Baby food

Last week, I discussed an article from The Conversation regarding the advances in meat preservation (refrigeration and canning) in the Victorian era that led to much greater meat consumption in England (and, presumably, elsewhere).

The author noted that there was a bit of push back against imported meat, however, which included this rumour:
In my archival research, I’ve even discovered concerns that boiled human babies were entering the food chain.
By coincidence, I've noticed two other reference to baby eating recently in Netflix shows I've been watching:  Fargo (season 3, which is very eccentric), in which a Russian bad guy talks about parents eating babies during the famines; and The Alienist, with a serial murderer writes a ranting letter about filthy foreigners eating babies.(Or was it kids generally?  I could be wrong there..)

This is a topic of which I know little.  Googling it comes with various bits of information of some interest:

*  some sites note it as a form of the old Jewish blood libel.  It's sort of funny how the rumour was easily transferred from Jews to Christians as the villains.  From a 1976 article:


How come with Christians it became specifically babies?  And then, with Christians, the accusations became of Jews using the blood of children, not babies.   All peculiar, how it changed over time.

*  As for Russians and famine - there are plenty of horrible photos on line, but it would seem anyone (children in particular?) was at risk of being eaten, not specifically babies.

*  More recently, it's the Chinese in particular who have been in the firing line, in significant part because of a stupid performance artist who had photos taken of him eating a fetus, leading Snopes to run an article "Fact Check:  Are human fetuses 'Taiwan's hottest dish'?"  (Most people doubt it was a real fetus in the pics.)

Apparently, this story did a big sweep through tabloids back in 2001, leading to Taiwanese officials complaining to a Malaysian publication:
Government officials have filed a complaint with a Malaysian weekly tabloid that published an unsubstantiated story that an unnamed local restaurant had served human fetuses and the bodies of babies to its customers.

The publication has promised to publish a correction in its next issue.
But there are many other stories on the 'net - usually from tabloid-ish or otherwise unreliable sources - claiming that Chinese doctors eat aborted fetuses for good health (or sexual virility!) 

I have complained before that one big thing that really needs to change about Chinese culture is its stupid belief that eating certain animals gives particular vitality or health benefits.   If people there would spend less time interested in consuming rare and endangered animals for illusory benefits, maybe they would also stop being targetting for rumours of fetus eating, too.

Anyway, this is an unpleasant topic.  Moving on...

Regulatory failure noted

Am I the only person flabbergasted that a high rise apartment building in Melbourne can start to burn up because of cigarette flung off a balcony?
MFB Fire investigators spent most of the day at the apartment building and concluded that the most probable cause was a discarded cigarette that ignited combustible materials stored on the balcony.
The only mild encouragement from that is that at least it doesn't mean that the cladding itself was directly ignited by the cigarette butt.   Some small comfort, though.   The building was apparently audited for safety for its cladding after the Grenfell Tower disaster.

Seriously, what were architects, builders and regulators thinking when putting any "combustible in the right circumstances" material on a high rise building?     Has this practice stopped completely yet?

Good grief

Pretty much from the "only in America" category, I see a Vox headline:
Why Bible-inspired diets and fitness plans are catching on
Ezekiel bread, the Daniel fast, and Holy Yoga all take their cues from Scripture.
 People who want to get fit, lose weight, and eat more healthfully often turn to trainers and dietitians for advice. But today, they might also to turn to a Bible-inspired or faith-based wellness program. Take actor Chris Pratt. He announced last month in an Instagram story that he was on day three of the Daniel fast.
“It’s 21 days of prayer and fasting,” he explained.
The program takes its name from the Old Testament prophet Daniel. While it’s called a fast, it does not require complete abstinence from food. Instead, “some foods are eaten while others are restricted,” according to the Daniel fast website. Those who go on the fast hope to not only get their weight and diet under control but also draw closer to God.
Look, Pratt is a likeable enough screen presence, but his strange mix of apparent seriousness about religion and willingness to talk a lot of sex jokes (as well as getting divorced with a young son at home) is a bit odd, if you ask me.  And peculiarly American too.

Time travel murder needed

I see that the matter of whether it's ethical (or just a good idea) to go back in time and kill baby Hitler was on the internet recently (see the Vox explainer here); but I have a better idea - someone needs to consider going back in time to kill Dorothy Mackellar.   

If you are not Australian, you may need to be informed:  she was an Australian poet who wrote a piece beloved of primary schools of my era which nearly every Australian (at least over the age of 50) has had to learn. 

The problem:
I love a sunburnt country,
A land of sweeping plains,
Of ragged mountain ranges,
Of droughts and flooding rains.   

means that climate change deniers, like those that flood (ha, a bit of a topical pun) Catallaxy, think that the one line in there eans that they never have to admit that record breaking rains and associated floods in Australia are being worsened by climate change. 

OK, maybe she doesn't need to be killed.   Just someone get their hands on that pretty turgid piece of writing and tear it up.   

Tim being a naughty boy

Tim Wilson has been attracting much attention for his ridiculously blatant partisan hijacking of the economics committee.

One wonders - could Victoria polling for Liberals be so bad that even his seat is in danger?  It would explain the hint of desperation that his actions here indicate.

In tech news best kept away from paranoid schizophrenics...

Lasers have been used to send targeted, quiet messages to someone from several meters away, in a way that no one nearby would be able to hear.
How it works: To send the messages, researchers from MIT relied upon the photoacoustic effect, in which water vapor in the air absorbs light and forms sound waves. The researchers used a laser beam to transmit a sound at 60 decibels (roughly the volume of background music or conversation in a restaurant) to a target person who was standing 2.5 meters away. 
A second technique modulated the power of the laser beam to encode a message, which produced a quieter but clearer result. The team used it to beam music, recorded speech, and various tones, all at conversational volume. “This can work even in relatively dry conditions because there is almost always a little water in the air, especially around people,” team leader Charles M. Wynn said in a press release. Details of the research were published in Optics Letters. 
Next steps: In theory, the technique could be used to direct a message to a single person at range, without any receiving equipment. The team plans to get the technique to work outdoors, at longer ranges. It isn’t too much of a stretch to see it being used for military or spying purposes, and of course there’s always the ever-present specter of super-targeted advertising.

The 1TB phone will soon be here

Samsung announces it has a new 1TB chip for use in mobiles and tablets.   It is, quite frankly, incredible what is being fit on a chip this size:
On its new drive, despite having the same 13 x 11.5mm dimensions as smaller flash drives, Samsung says its new 1TB module boasts sequential read speeds of up to 1,000 Mbps, twice that of a typical SATA-based laptop SSD. Additionally, random read speeds are allegedly 38 per cent faster than on an equivalent 512GB flash drive, with random writes speeds as much as 500 times higher than a high-performance microSD card.

"Fatherhood" is rarer in nature than I realised

From an AEON essay, by an anthropologist who got into studying fatherhood:
In the first instance, as someone who began her graduate career as a primatologist, I knew that fathers who stick around, rather than hot-footing it as soon as copulation is complete, are vanishingly rare in the primate world, limited to a few South American monkey species and completely absent from the apes, with the exception of ourselves. Indeed, we are among the only 5 per cent of mammals who have investing fathers. I knew that, given the parsimonious nature of evolution, human fatherhood – with its complex anatomical, neural, physiological and behavioural changes – would not have emerged unless the investment that fathers make in their children is vital for the survival of our species.
The whole essay is interesting.  Go read.

Nothing like a good chart, part 2


Nothing like a good chart


Sounds interesting

NPR talks about a film looking at the stories of (some) Jews who chose to "hide in plain sight" from the Nazis in WW2:
Hanni Weissenberg, now Hanni Lévy, survived as a Jew in Nazi Germany.

Today, the petite and lively 94-year-old lives in Paris. Earlier this month, she returned to Berlin, her home during the war years, to attend the screening of a film about her and other Jews who survived while hiding under the noses of the Nazis.

The Invisibles, a German documentary-drama based on the accounts of four survivors, opened Friday in the U.S....

Schieb says about 1,900 Jews survived the war while hiding in and around Berlin.
