Robert Best2,685Google+ Relevance CircleWhat people of "relevance" do we have in common? Care to share?This big shared circle contains my most "relevant" circles according to G+. It also only contains people/profiles who post publicly (Either occasionally or prolifically).Do you recognize others in the list? (I think the probability is high)As far as I know, the visual beside the "Add people" button below shows you the 8 people from this circle who are most "relevant" to you. Also, if you click that add people button, the list inside is ordered by "relevance".Some people in this circle I know very well... others I haven't met at all (Besides interfacing with what they share publicly on G+) I'm curious, what circles do we share of high relevance? Give a few people shout outs! Let's have a random chat.You were likely notified of this post... I normally don't share to any of my specific circles, so as to avoid sending out unwanted notifications... But since I have you and your attention here... HELLO! Have we talked before? Why do you think I have you circled? What's of relevance for you? (Besides people on G+) If we do know each other... Have we been in touch lately? If not, let's please catch up!2015-03-03 01:03:39455111

Introducing Google+ Collections, a new way to group your posts by topic

Our happiest Google+ users are those who connect with others around shared interests and passions. So we set out to give people a place to express the things they love. Today, we’re announcing Google+ Collections, a new way to group your posts by topic.

Every collection is a focused set of posts on a particular topic, providing an easy way for you to organize all the things you’re into. Each collection can be shared publicly, privately, or with a custom set of people. Once you create your first collection, your profile will display a new tab where other people can find and follow your collections.

Posts in collections you follow will appear in your Home stream, with a link to easily jump right into the collection so you can get to similar content from that author. Collections give you agre... more »

"Butterfly" is a wonderfully unusual word: although every language has a word for it, in no two languages does the word tend to be related.

On saying butterfly in many languages when it does not have cognates (words that are similar in sound, spelling and meaning). "[Holly Tooker] sang out: “I can say ‘butterfly’ in 139 languages! Anyone want to challenge me or teach me a new one?”

Standing nearby, a man in a straw fedora and a periwinkle T-shirt wondered if she knew the word in Basque.

Ms. Tooker asked him if he wanted it in “Euskara Batua,” standardized Basque, or in a regional dialect, spoken by about 710,000 people near the coast of the Bay of Biscay.

“Batua,” the man, Maurice Algarra, said.

“Tximeleta,” Ms. Tooker replied.

“That’s right!” said Mr. Algarra, 50, whose grandparents illegally spoke Basque to him when he was growing up in Franco’s Spain.
[...]
“Butterfly” has stymied language experts for decades. It is the one common word that does not have cognates — words that are similar in sound, spelling and meaning — in related languages, even closely related ones. “Spanish, Portuguese, Italian, French — each one has a different word for ‘butterfly,’ ” said William Beeman, chairman of the University of Minnesota’s anthropology department who has written on the anomaly. “This flies in the face of what we know about how languages work. And when someone hears you say ‘butterfly’ in their language, they know you’re speaking their language.”"___"Butterfly" is a wonderfully unusual word: although every language has a word for it, in no two languages does the word tend to be related.

We get articles all the time about how automation will affect jobs, and after a while they all blur together. I have to say that this one from the Economist is no different: there is almost nothing in it that you haven't heard fifty times. Except for this one chart.

The fact that some telemarketers, accountants, and retail salespersons are almost certain to be replaced by automation in the next two decades should hardly be surprising. (NB that that's "some," not "all:" nobody is saying that these jobs won't exist in twenty years) 

What I find fascinating is that they estimate a 0.8% chance that computerization will lead to job losses among clergy.

I don't know exactly what they're anticipating, or how they came around to this number. All I know is that I find this fascinating. I can't shake this mental picture of a robot priest... more »

What I find fascinating is that they estimate a 0.8% chance that computerization will lead to job losses among clergy.

I don't know exactly what they're anticipating, or how they came around to this number. All I know is that I find this fascinating. I can't shake this mental picture of a robot priest presiding at services, or of a digital rabbi sorting through centuries of responsa to try to assemble a meaningful Talmudic view of an issue, or of an electronic Imam talking someone through a spiritual crisis over IRC.

Or perhaps they had something simpler in mind -- will people, instead of talking to a cleric about something, instead look it up on the Internet? I could see this going both well and badly: on the one hand, people taking more personal responsibility for their inner lives. On the other hand, think about what the Internet has done for hypochondriacs.

Of course, this doesn't take into account the possibility of job gains among the clergy because of automation: not simply because of the further opportunities to shepherd one's flock over the Internet, but because increasingly intelligent computers may themselves develop some kind of religious need.

I suspect that this would be very different from the needs of humans. A fundamental aspect of our minds is a tendency to err on the side of assuming that things are animate and have minds: this is a very healthy kind of error to prefer, since our ancestors who mistook a dead hyena for a live one looked foolish, while our ancestors who mistook a live hyena for a dead one did not, in fact, end up being our ancestors at all. Computers don't have that pressure on them: but instead, as we build increasingly sophisticated AI's which sift through data, they err on the side of apophenia -- of seeing patterns where there are none. I could imagine the computers of two decades from now developing an increasing obsession with The Pattern, that underlying, all-explaining structure which is perpetually just out of their reach. The clerics of that age may well be engineers who help them come to grips with their limited understanding of this.

So having no idea how they arrived at these numbers, I'm going to assume that either (a) we're looking forward to a future of robotic clerics serving humans, and human clerics serving robots, but apparently slightly more of the first than the second, or (b) they pulled these probabilities entirely out of their asses.___

If you're running a large enough organization, you're going to find yourself doing certain standard things, like accounting, expense reports, and HR. And that's apparently true even if your organization is a shadowy international terror group. Thanks to recently-declassified data, we have (I kid you not) al-Qaeda's job application form, and this lecture (https://youtu.be/VpJqFpBwAm8) about their management procedures, complete with slides of things like their insurance forms, reimbursement procedures, NDA's, and the like.

It's a weird mixture of the surreal and the mundane. "Have you invented or researched anything in any domain?;" "What other languages do you speak, and at what level?;" "Do you wish to execute a suicide operation?;" "What objectives would you like to accomplish on your jihad path?;" "Who should we contact in... more »

There is nothing so unusual in this world that it does not end up being weirdly mundane.

Today I present to you a bunch of photos and videos made by two professors who have a lava machine. Literally: it melts basalt and lets them pour it in various ways, simulating the kinds of things that happen to lava when it leaves volcanoes.

You can see some great pictures here of it striking ice, water, and organic matter, in the form of a banana.

The banana never stood a chance.

Some great data visualizations of the way religious affiliation and political perspectives align in the US, based on the Pew Religious Landscape Survey. In this graph, the size of the circle indicates number of people, and its position shows that group's mean position on environmental regulation and on evolution. (What you don't see, unfortunately, is the distribution within those groups -- that's especially important for large groups like "Catholic" and "nothing in particular." Alas, Pew hasn't released the dataset yet -- they only do that after they're done publishing all the papers -- so we can't generate those ourselves, either)

This visualization of Pew’s Religious Landscape Survey (2007) examines the relationship between support for environmental regulations and support for evolution amongst different religious groups. The bubble chart scales each group's response based on relative population size (i.e. Catholics have biggest bubble). An immediately obvious conclusion is that support for evolution aligns with support for environmental regulations (Jehovah's Witness is a major outlier).

There are lots of small, interesting bits here. For example, Jews who are neither Conservative nor Orthodox align fairly closely with atheists on both graphs, while Orthodox Jews are fairly close to the American Baptist Church (generally considered to be a mainline protestant group) Conservative Jews align with non-C/O Jews on the first graph, and with Orthodox Jews on the second. Agnostics, meanwhile, align with atheists on the first graph, but not as much on the second: they apparently tend to prefer fewer government services.

This is an absolutely lovely restaurant review. It's all about the wonderful features of eating there. The slight chemical flavor of the margaritas, for example, helps you keep your alcohol intake under control; by serving fondue lukewarm, instead of hot, they protect you from the risk of any trips to the emergency room.

It also has useful and specific recommendations, such as: "The flour tortillas are outstanding. Every time I went to Javelina, in fact, those flour tortillas were the best thing on the table."

The lack of stars in this review is not a printing accident.

Fair warning: This article talks about death. It talks about embalming and decomposition, and it talks about the "cadaveric ecosystem," also known as the necrobiome: that host of microscopic and macroscopic creatures which gradually transform us from meat into life. 

We are only beginning to understand this aspect of the life cycle. Much of the recent research has been driven by forensics: the precise chronology of various changes (from the spread of gut bacteria into the rest of the body, to the life cycle of cadaveric insects) can be used to establish time of death with surprising accuracy. Other aspects are pushed by medicine: we are only starting to understand the various microbiomes of the body, from our guts to our genitals to our noses, each of which is host to an entire ecosystem which interacts with the rest of our bodies in ways critical to our survival.

Other aspects are pushed by medicine: we are only starting to understand the various microbiomes of the body, from our guts to our genitals to our noses, each of which is host to an entire ecosystem which interacts with the rest of our bodies in ways critical to our survival. When we die, the balance between them and our bodies shifts, and we see what those same bacteria would do without our immune systems regulating them.

Everything that happens following death is part of this cycle. Meat rots because bacteria don't have teeth; they're competing for the windfall of resources with anything from other bacteria to hyenas, and as they can't chase their competition off in person, they emit toxins which they're immune to, to claim that chunk for themselves.

To me, this subject has a particular beauty, because it's such a poignant reminder of our place in the wider picture of the world. Death is far from an ending; it is a moment where tremendous wealth (as life measures it) is suddenly unlocked, made available to a host of creatures. We are used to thinking about this when we talk about biology: a whalefall is a crucial event in the life of the ocean floor, a dead animal a bustling center of activity in the desert. But it applies to us as well. You can rest assured that the blowflies and ravens will cherish you just as much as they will cherish your neighbor.

The MTA made a great little video, in the style of an 8-bit video game, explaining why holding a train at the right time can speed up service overall.

The secret is this: if there's a gap between trains (because one train got delayed for reasons outside of its control) then lots of people start to build up on the platforms in the gap. That makes each loading and unloading slower, which effectively delays the train more, and the gap grows. To fix this, the MTA will delay the train in front of the gap; that breaks the gap into two smaller gaps, which prevents crowds from building up, and lets the gaps heal. The video illustrates exactly how that works.

I cannot even begin to understand the patterns by which news editors are choosing which headlines to put front and center by now. Surely, even by the standards of Waco, TX, a pitched battle in the streets which left 9 dead, 18 wounded, and 170 arrested and charged with variations on the theme of "murder" would merit being treated as a major national news story, and perhaps running above the fold for more than two hours?

At least the story below gives some fairly good background on who the various groups involved were, and on what was going on. Apparently this was not unexpected: members of both the Bandidos and the Cossacks had been instructed to arm themselves and come to North Texas, and they ended up converging at a restaurant in a shopping mall.

It's not exactly clear how long the battle lasted, but it's well above the scale of what I could call a "riot" with a straight face, and the rather enthusiastic use of ranged weapons (in addition to clubs, chains, and the like) seems to take it above the realm of mêlée as well. 

Seriously, I have no idea what to make of this, except that this is pretty crazy even in Texas.___

This is a great collection of graphs about the ways that various jobs have appeared and disappeared in the US economy from 1850 to the present. You can see the decline of farming as a mass profession, the rise and fall of factories, and how the two most guild-regulated professions -- doctors and lawyers -- have held fairly steady.

When you look at the first graph, make sure to click through to the link to see how the number of jobs has changed; it's very different from the change in the percent of jobs, seen below, because the population has surged. Farming has dropped from 51% of the labor force to 1% of the labor force since 1850, but that's actually only a drop from 2.6 to 1.6 million people. White-collar jobs, in the meantime, have gone from 567,000 people to almost 89 million -- an even bigger surge than the graph below would suggest.

Machines and automation have long been harbingers of job destruction. The rise of farming technology during the early 20th century shifted workers from the field to the factory and eventually a boom in white-collar jobs. This NPR piece examines how machines have changed industries over time and led to the current service sector growth.

A good short article underlining a simple point: the problems in our economy over the past decade are likely neither cyclical nor simply the consequences of poor policy decisions, but structural. While the recent chaos included some of the familiar mechanisms of stupidity mixed with greed - e.g., the cycle of fading memory leading to poor oversight, and thence to scams, bubbles, and collapses in the form of the mortgage crisis - those are the sorts of things which would normally pass in a few years. What we are seeing here are structural changes in the availability of jobs, their real pay, the associated opportunities, and so on.

NB that these aren't really new: they're the history of the past 200 years. But now, they're affecting the previously comfortable upper middle class in ways they hadn't before - that college degree no longer buys what it used to - and so it's... more »

Wages for the typical graduate of a four-year college have dropped more than 7 percent since 2000, and the labor force participation rate of the young has been falling. One consequence is that young people are living at home longer and receiving more aid from their parents. They also seem to be less interested in buying their own homes.___A good short article underlining a simple point: the problems in our economy over the past decade are likely neither cyclical nor simply the consequences of poor policy decisions, but structural. While the recent chaos included some of the familiar mechanisms of stupidity mixed with greed - e.g., the cycle of fading memory leading to poor oversight, and thence to scams, bubbles, and collapses in the form of the mortgage crisis - those are the sorts of things which would normally pass in a few years. What we are seeing here are structural changes in the availability of jobs, their real pay, the associated opportunities, and so on.

NB that these aren't really new: they're the history of the past 200 years. But now, they're affecting the previously comfortable upper middle class in ways they hadn't before - that college degree no longer buys what it used to - and so it's unsurprising to see it in the news.

Surveying people about their dreams brings out commonalities, but also regional differences. I would love to see this done in depth, to see a list of common dreams worldwide, perhaps, along with a map of the dreams which are distinctive to particular areas. But even just this small collection has a special fascination.

Around the world in dreams. Apparently everyone flies. :) But other aspects vary wildly. ___Surveying people about their dreams brings out commonalities, but also regional differences.

I would like to present you with some data which is almost certainly useless to you, unless you happen to need to think of, say, a distinctly Coloradan (atherosclerosis), Mississippian ("other and unspecified malignant neoplasms of lymphoid, hematopoietic, and related tissues"), or Louisianan (syphilis) way for someone to die.

Writers, of course. That suggestion is meant for writers. Why, did you have some other reason you wanted to--- no, nevermind. It's probably best if I don't know ahead of time, so that I can't be asked to testify.

The original paper is at http://www.cdc.gov/pcd/issues/2015/14_0395.htm , and clarifies that (like other "most distinctive" maps you may have seen on the Internet) what this shows is the cause of death whose rate is farthest above the national average frequency.

Professor Mark Post of Maastricht University, one of the world's foremost experts on synthetic meat, was responsible for that first fully lab-grown burger a few years ago which was generally reviewed as tasting not bad. At the time, it cost nearly a quarter of a million dollars to make - but in a new interview with the Australian Broadcasting Company, he says he's gotten the cost down to AU$80 per kilo - about US$29 per pound. In a few years, this could easily become cost-competitive with ordinary beef, and then even cheaper: cows are, if you think about it, an awfully inefficient way to convert water and grain into protein, going through that whole "life form" business in the interim.

I suspect that it will be a long time until lab-grown meat tastes as good as cow-grown (it's not easy to mimic the fat marbling process in good beef), and in particular lab-grown steaks will be a much longer time coming. But that's far less noticeable in ground beef, and it's not hard to imagine a future where that can be factory-produced far more cheaply than cattle, with cow steak becoming more of a luxury good.

The consequences for human diet and health may be profound: it makes protein suddenly a lot cheaper and easier to come by, even as changing climates can play merry hell with existing ranching.

You know, I hadn't thought about it this way before, but the essay makes a compelling case: The Joker is really the hero of this story. Batman is weirdly overfunded and incompetent -- which is, of course, the traditional problem with Batman. ("You're going to invest how much in cleaning up the city? My god! Imagine all the schools and housing we could create, how many new jo... you're going to spend this on a bunch of armor and a car so you can beat up muggers? Oh. I see.") But the Joker is going out there and actually making a difference in rubbing out crime in the city -- and he seems to be going about it with a purpose.

But the Joker is going out there and actually making a difference in rubbing out crime in the city -- and he seems to be going about it with a purpose.

I always liked these alternate perspectives. I remember walking out of X-Men: First Class several years ago and being profoundly confused by it; we have two guys with super-powers. One of them is an Auschwitz survivor who uses his powers to hunt down Nazi war criminals. The other of them seems to mostly use his powers to get laid, and is perpetually riding just this close to date rape. When they get pulled into political machinations, and it becomes clear that the mutants are going to be registered, indexed, "encouraged" to become ordinary people, all the things that would make anyone who survived Germany in the 1930's panic, the first one makes a stand against it and wants mutants to live freely and proudly, and tries to organize them so that they have the muscle to stand up to such demands, knowing that they'll never be accepted; the other one urges cooperation, that it'll all be OK if they just work within the system.

Wait, the second one is supposed to be the hero, and the first one is the villain? Xavier (#2 for those who haven't seen this) comes across as somewhere between naïve and deluded; Lensherr has the serious realism of someone who's seen just what the world offers in these cases. I'm pretty sure, given the choice, that I know which side this movie convinced me to take, and it sure as hell isn't Xavier's. 

This is something important in stories in general: Sometimes the story seems to have the hero/villain dichotomy printed on the label, but you can never really understand why, and it makes as much sense, if not more, from the opposite perspective.

One of the great masters of doing this on purpose is Hayao Miyazake. His Princess Mononoke is an excellent example: everyone in this war is acting for completely comprehensible, reasonable objectives, and everyone's goals make perfect sense from their perspective. But added together, they're a recipe for a bloodbath, and the real hero proves himself by preventing that.

Television has recently done an excellent job of adopting this approach, as well. Two shows which particularly come to mind are Fringe and The Americans: in both, we have two sides fighting an increasingly bloodthirsty war, and it would be very easy to pick one side as "the good guys" and the other as "the bad guys." But we see the stories through everyone's eyes, and it's extremely clear that each person is, in complete honesty, fighting for what they believe to be right, and with good reason. Fringe's "Walternate" has every reason to believe that the other world is trying to invade and destroy his, and given that they started off by kidnapping his only son, his militaristic attitude is quite understandable; and he's the closest thing the story ever had to a villain. In The Americans, listen to Elizabeth express her disgust with all the things broken in capitalism, or Stan his disgust with the KGB; everyone has real reason behind their patriotism. 

Broadly, I think this is something which always makes for the best stories: a sharp conflict, wherein all the perspectives actually make excellent sense. 

Movies, especially big-budget ones, appear to have lagged behind television in this regard, but this sometimes creates the wonderful moments of dissonance where you realize that the script itself did achieve this goal, and it's only the marketing materials or the directing choices which tried to paint one of the agonists as the hero. In a strange way, that can be even more rewarding than when it's overt: you get what you thought was a simple story, but then you peel back the layers a bit, and discover a moment of Fridge Brilliance.

On the subject of reading statistics carefully: This article deconstructs the latest viral statistic ("1% of people control half the world's wealth!") and talks about what it's really measuring. The answer is that it's measuring a kind of weird number: the American med student who just graduated with hundreds of thousands of dollars in debt is considered to have far less wealth than a rural Chinese subsistence farmer.

What this means, of course, is that the statistic doesn't measure what you think it does, and the quantity it measures isn't really a useful one for understanding the distribution of resources in the world. What would be really useful is a measure of "effective wealth," which would really measure someone's ability to get resources when they need them.

Oxfam says, and with some reason, that even though the current measure is a poor one, it still points to something important. I think that's true, but in an extremely limited way. It makes for good sound bites, and if we had a real metric the actual number for this would probably be fairly close. But if we want to use this for anything more than PR - if we want to use it to actually solve problems, which means analyzing the real distributions of wealth, understanding what shapes them, and so on - then we need real metrics, not PR bullshit.

"For too long, we have been a passively tolerant society, saying to our citizens 'as long as you obey the law, we will leave you alone'"

It's sometimes easy to forget that European and American notions of the rule of law aren't all that similar. For all that Cameron's quote sounds alarming, the actual laws being proposed are even more so; they would grant courts the power to "silence any group or individual they believe is undermining democracy or the British values of tolerance and mutual respect," banning them from doing things like speaking in public or forming organizations.

"For too long, we have been a passively tolerant society, saying to our citizens 'as long as you obey the law, we will leave you alone'"

It's sometimes easy to forget that European and American notions of the rule of law aren't all that similar. For all that Cameron's quote sounds alarming, the actual laws being proposed are even more so; they would grant courts the power to "silence any group or individual they believe is undermining democracy or the British values of tolerance and mutual respect," banning them from doing things like speaking in public or forming organizations. 

The UK has always had a very different approach to speech than the US. Libel laws are perhaps the most famous illustration; in the US, truth is an affirmative defense to libel -- that is, if you can prove that what you said is true, then it's not libel. (Which is key to the operation of the press) Under UK law, libel isn't an offense of making false statements which damage someone's reputation; it's about damaging someone's reputation, period, and so "the greater the truth, the greater the libel." This has led the UK to be such a site of "libel tourism" -- that is, of powerful people suing anyone who speaks against them -- that a few years ago, the US decided it would refuse to honor or assist in any UK libel prosecutions whatsoever.

Also relevantly, the UK has its (in)famous "anti-social behavior ordinances," the template for the new proposal, which permit courts to issue injunctions banning individuals or groups from any kind of behavior they consider to be detrimental to society, without a specific law banning it. (The non-uniform application of these laws as a function of things like race and class happens about exactly as you would anticipate)

These are far from the only examples, and what they illustrate is a fundamentally different approach to the rule of law: in European law, the power of the government to rule -- that is, to establish and enforce norms -- takes precedence over any individual rights, whereas in the US, the reverse is the case. 

However, these are far from uncontroversial, even within Europe; as the article below shows, this particular law was stopped for years because the Conservative Party couldn't convince their largest coalition partner (the Lib Dems) that this was a good idea. It was last week's election that gave them the votes to do this without anyone else. The BBC reports that "there is likely to be some opposition in the new Parliament on the grounds that some of the plans could infringe people's right to free speech," but whether this opposition will actually amount to anything remains to be seen.

The main reason I'm highlighting this isn't the global significance of the law, so much as that it's important for understanding the British (and more generally, the European) approach to the law and to individuals. When we read about controversies of policy like the "right to be forgotten" between the two sides, it's worth understanding that in addition to our seeming similarities, there are extreme differences of culture and law at work, too.

Results from game theory and statistics about how to maximize your odds of winning at things from poker to The Price Is Right. It turns out - I did not realize this - that some of the "games" on these game shows are actually games simple enough to have guaranteed winning strategies. "Now or Then," one of the regular features on The Price Is Right, is about as complicated as Tic Tac Toe... and yet over the past thirteen years, people have won it only 68% of the time, because they're so distracted by a superficial feature of the game ("guess which price is current!") that they miss that it's actually an idiotically simple game ("get three consecutive yes answers by asking questions!").

For all that this piece is beautiful to look at, the process of its making is even more beautiful. The stripes you see on the tiger? Each one of those is made from a separate piece of metal, a hole cut for it and the piece inlaid. The leaves? Gilded. The fur, the face? Carved with an iron brush -- that is, a chisel.

It's tempting to look for bumper-sticker solutions to big problems like the California drought, now the worst in at least 500 years. (Maybe more: people are analyzing the records from further back) Blame the farmers, the big cities, the almond growers, the alfalfa growers. But as with any important problem, the reality is a lot more complicated, and this article does a good job of debunking myths of the form "if we just do X, everything will be OK."

Because it turns out that we've actually already done those obvious things. The problem, at this point, isn't that water is being wasted profligately -- although we could always improve efficiency further, and everyone is working on that. The problem is that there simply isn't as much water as there used to be, and we have to start to eliminate things that use water. Will that be wild rivers? Farmland? Drinking water? more »

Because it turns out that we've actually already done those obvious things. The problem, at this point, isn't that water is being wasted profligately -- although we could always improve efficiency further, and everyone is working on that. The problem is that there simply isn't as much water as there used to be, and we have to start to eliminate things that use water. Will that be wild rivers? Farmland? Drinking water? 

My guess is that "drinking water" won't be it, and that farmland largely will be, simply because it's a relatively small part of the state's economy, and if the price of water starts to go up (as it will, across the board, as supply goes down) lots of farmers will end up selling and going into some other line of work.

If you see farming as a per se good, that's obviously a problem, but for most people, at least, the main goal of farming is to produce food, so as long as the food supply chains remain intact -- which they likely will, because the only way water gets expensive faster than crops do is if you can grow the crops elsewhere where there's a better climate and still ship it to buyers -- it won't be a huge change. 

There's an argument about the net value of local farming, which I think does have some important merit from an engineering perspective (our current food infrastructure, based on shelf-stability and efficient long-haul logistics, strikes me as having way too many concentrated points of failure), but ultimately, local farming in drought-stricken lands is a kind of dubious proposition, so if things get and stay dry, I anticipate that farming will simply move elsewhere.

Not entirely, of course; as the article points out, it will still likely make plenty of sense to grow high-value crops like almonds and wine grapes for quite a long time to come. (And in fact, weather like this increases the quality of several fruit harvests; the wines from the coming years are likely to be quite good) But it's likely that California's agriculture will contract over the next decade.

The net result is: We need to continue to work on water efficiency, on spotting problems and fixing them whenever they occur, be they legal or engineering. Californians of all stripes need to work on this together, just as they have for decades, and as things continue to get dryer -- which they almost certainly will -- this will keep becoming more and more important. We should expect that the state's economy will change a good deal. But ultimately, in the long term even a major drought of this sort is on the scale of economy-affecting, rather than economy-destroying, so long as there are places elsewhere where crops can be grown, and food transport logistics continue to work well.

In the short term, things are considerably more complicated: you can't just magically turn some area into cropland just because it's suddenly climactically favorable, which means that you're going to have lots of transient shortages (and thus price spikes) of various agricultural goods as the transitions happen. These can be tremendously important: it was a sequence of droughts in Russia and Ukraine, and the consequent closure of wheat exports from those areas, which precipitated the Arab Spring.

So in the short term, lots of attention will be needed to keeping crop prices and production as stable as possible, which means to operational flexibility in agriculture on large scales; in the long term, we should continue to focus on continual improvements in water usage, because it ain't going to get any cheaper or more plentiful out here.

Math question which is probably obvious to someone out there:

Does every cellular automaton exhibit periodic solutions? (i.e., for any cellular automaton, does there exist at least one configuration A and positive integer p such that for any natural number n, A(np) = A(0)?) Failing that, does every cellular automaton at least have "spaceships?" (i.e., configurations periodic up to translation)

(This is really "today I haven't yet learned," because while I feel like I should know the answer off the top of my head, I really don't)

Edited to add: There's been a lot of great discussion in the thread, so let me sum up the key results so far here. Let N be the set of sites, S the set of states, T be the time-evolution operator on N⊗S, and P = ∩_k Range T^k.

Math question which is probably obvious to someone out there:

Does every cellular automaton exhibit periodic solutions?

Failing that, does every cellular automaton at least have "spaceships?" (i.e., configurations periodic up to translation)

(This is really "today I haven't yet learned," because while I feel like I should know the answer off the top of my head, I really don't)

Edited to add: There's been a lot of great discussion in the thread, so let me sum up the key results so far here. Let N be the set of sites, S the set of states, T be the time-evolution operator on N⊗S, and P = ∩_k Range T^k. 

(1) When S is infinite, it's easy (and kind of boring) to come up with completely aperiodic automata; for example, let S=ℕ, and the time-evolution rule simply adds 1 to each cell at each tick. So this question is most interesting when S is finite. In many cases, it will be convenient to take S = {0, 1}, since we could simulate any cellular automaton with a larger S with a two-state automaton that just uses some more sites.

(2) ∅⊆P⊆N⊗S. Every periodic state of T must be an element of P. Every element of N⊗S converges to an element of P under repeated applications of T.

(3) When N⊗S is finite, P is nonempty, and every element of P is periodic with period ≤ |P|. Thus for finite CA's, every initial configuration converges to a periodic configuration. This bound is minimal in that it's straightforward to construct CA's which have states of period exactly |P|.

(4) P = N⊗S iff T is reversible. If N⊗S is also finite, then every element of N⊗S is periodic.

(5) If T is homogenous (i.e., the rule is independent of N), then it maps any homogenous configuration N⊗{s∈S} onto another homogenous configuration.

If S is finite, then there is a nonempty Q⊆S such that the action of T on any homogenous configuration N⊗{q∈Q} is periodic with period ≤ |Q|. In this case, any homogenous configuration N⊗{s∈S} converges to one of these periodic configurations in no more than |S|-|Q| steps. 

(6) In particular, if S = {0, 1} and the CA is homogenous, then one of four things must be true, independent of N:
- The homogenous states 0 and 1 are both stable;
- The state 0 is stable, and 1 flips to 0 in a single tick;
- The state 1 is stable, and 0 flips to 1 in a single tick;
- The states 0 and 1 map to each other, and so both have period 2.

(Although NB that when N is infinite, it's not generally true that all states ultimately converge to a periodic state, simply that at least one such state exists)

(7) When S = {0, 1}, we might define an additional constraint of "compact configurations," i.e. configurations where only finitely many elements of N are nonzero. It's easy to construct automata (with infinite N, of course) where there are no compact periodic solutions, and there are several examples in the thread.

So the brief answer to the original question is:
- If S is infinite, generally no.
- If S is finite and N is finite, every state converges to a periodic state in finite time, with period ≤ |P|.
- If S and N are finite and the CA is reversible, then every state is periodic with period ≤ |S|^|N|.
- If S is finite and the CA is homogenous, then every homogenous state converges to a periodic homogenous state, and the sum of the number of steps needed to converge and the period of the resulting state ≤|S|. However, not all homogenous solutions are compact.

Not-yet-answered question:

In general, if N is infinite and S is finite, what are the conditions on T for a periodic solution to exist?

Food panics are nothing new. In the first half of the 20th century, people were very concerned about the purity of their food, and often with good reason. The symbol of pure, wholesome food then was food made in a modern, industrial factory -- not in some dingy local shop, with dubious standards of cleanliness. Wonder Bread came on the scene in 1921, and was an immediate hit: it took bread, the staple food of most societies, and made it "clean" and "healthy."

White bread is nothing new: debates over the relative merits of white and wheat bread go back to ancient Greece.

Food panics are nothing new. In the first half of the 20th century, people were very concerned about the purity of their food, and often with good reason. The symbol of pure, wholesome food then was food made in a modern, industrial factory -- not in some dingy local shop, with dubious standards of cleanliness. Wonder Bread came on the scene in 1921, and was an immediate hit: it took bread, the staple food of most societies, and made it "clean" and "healthy."

And "white."

The article (and podcast) below is a great introduction to the rather bizarre history of Wonder Bread -- and how the food, and social, fears of the early 20th century shaped the foods of the latter half of the century.

A few weeks ago, this image showed up on a notorious hyper-granola website called "The Naked Label," along with the reminder that "we cannot make better food than nature." I want you to look at it for a moment, and tell me if you spot anything wrong with this image.

Next, I want to get this on a t-shirt, with the back of the shirt printed with detailed biological and medical information about the fungus depicted here -- the 100% all-natural amanita muscaria, which is both poisonous and psychoactive. In fact, I want a whole series of shirts with this same logo, and all sorts of other natural things depicted -- say, a plague bacillus, a golden dart frog, and maybe someone getting eaten by a bear.

But surely we all know what the website meant, and I'm just needlessly nitpicking on their rather dubious art direction? No: I'm criticizing them for the "naturalistic fallacy:" the belief that "natural" things are good, and "artificial" things are bad, even without any real understanding of what one and the other really are. It's a way to perform one's social class ["I only eat natural foods, of course; I would never let my children encounter anything packaged."] while drawing political and financial ire at technologies which are out there saving human lives every day. We get to worry about obesity epidemics because until a few years ago, we were worried about famines. I know: several of my family members nearly died from them.

There was recently an excellent article about real food concerns and how to separate them from populist nonsense; if you're at all interested, I recommend it.

Isochrones are a beautiful way to convey a huge amount of information about a travel network. You can see how central places are, see the health of various links, see the places which are systematically isolated, and all in terms of one of the most useful quantities to your actual planning: How long does it take to get there?

I'm somewhat surprised that more transit agencies don't use real-time isochrone maps as a way to show the grid. I'd really love to see one which also includes air and land links, where you can flip various modes of travel on and off, and view the worldwide travel network from any origin point in near-real-time.

An isochrone map depicts curves of equal travel times between two points and is commonly used with transportation planning. This blog explains the history of the isochrone map and presents a beautiful map showing transit times of the Austro-Hungarian Empire Railway Network in 1912.

I am afraid I must report that our schools are run by utter fuckwits. But you probably already knew that. 

These are the sorts of answers to the questions that you photocopy and hand out to all the students, because whoever this girl is? She knows how to answer those questions.

(The caption suggests she should do marketing for a condom company -- that's a pretty good idea)

If kids aren't allowed to swear when answering a worksheet like this, where they're supposed to be learning to assert their independence and refuse bullshit excuses against condoms, then schools are throwing out babies with the bathwater.

At most the teacher should have requested that the student use f*** or an equivalent.  And fine, she can lose a point for not putting her own responses on the back as directed.  But her responses are perfect as they stand and should be applauded.

Don't ask for people's voices if you don't want to hear how they choose to speak.

Chicago's city council has unanimously approved reparations for the victims of John Burge, a former police commander who for decades ran a "midnight crew" which systematically tortured black suspects. What's most important about this settlement isn't the dollar amount -- the city has already paid over $100M to settle Burge-era cases -- but some other critical things that go with it.

One important part is the city's frank admission of guilt: these reparations were not demanded by a court settlement, but were done voluntarily by the council at the instigation of Mayor Rahm Emanuel. 

But perhaps the most important thing is a small provision in this: the city will incorporate the Burge case and its legacy into 8th- and 10th-grade history curricula.

This is something which is often ignored in significant settlements, but it's tremendously important in that systematic evils get swept under the rug. It's easy for generations to grow up thinking that things are all OK, that the police will only go after "bad people," and that the world is fundamentally just -- and thus that anyone who is the victim of something must have done something to deserve it -- if they don't ever learn that it's not so.

I can't think of any other such case in which a city has taken the active step to make sure that a case isn't forgotten, and that students in particular learn about it. This is something very important, and to be watched and probably imitated by others in the future.___

This sits somewhere on the line between "today I learned" and "today I learned what?!," because it's a set of four very short animations about unusual duels in history. Each of them, in the grand tradition of duels, illustrates how inflated displays of ego and weapons don't mix, but the choices of weapon (billiard balls at 12 paces?) and the fact that they managed to find seconds for some of these things (are you really going to volunteer to go up in a hot air balloon with someone else, just so they can be shot at?) are kind of impressive.

"The Coolness Spiral of Death:" a mathematical study of why people in their thirties don't like that damned noise those kids listen to these days. (For arbitrary definitions of "those kids" and "these days")

As users age out of their teens and into their 20s, their path takes them out of the center of the popularity circle. Until their early 30s, mainstream music represents a smaller and smaller proportion of their streaming. And for the average listener, by their mid-30s, their tastes have matured, and they are who they’re going to be.

Two factors drive this transition away from popular music.

First, listeners discover less-familiar music genres that they didn’t hear on FM radio as early teens, from artists with a lower popularity rank. Second, listeners are returning to the music that was popular when they were coming of age — but which has since phased out of popularity.___"The Coolness Spiral of Death:" a mathematical study of why people in their thirties don't like that damned noise those kids listen to these days.

What we see is that teenagers have a much stronger preference for more popular music, with tastes gradually becoming more eclectic until the mid-30's, when tastes seem to level out. The researchers say that this is probably a combination of effects: discovering more music over time, personality changes, and "taste freeze," liking the same stuff even as it becomes less popular.

The effect is more pronounced for men than for women, as you can see below, but it's even more pronounced for parents: they found that when you look for people with kids (as evidenced by their music streams containing a significant fraction of children's music), tastes become significantly more eclectic, on the whole, and the difference between men and women vanishes.

There's plenty more in this article, and it's a great little bit of data mining.

The first road-legal self-driving truck has been issued a license plate by the state of Nevada. The vehicle is "NHTSA level 3" certified, which means that it can drive itself, but a driver is required to be able to take over control if the need arises. (Level 4, at which nothing has yet been certified, can operate completely autonomously, without any humans paying attention at all)

Daimler (which owns Freightliner) is pitching this as a solution for driver drowsiness, which is a significant issue for truck drivers. Going forward, this is likely to be an important milestone in getting autonomous transport into our day-to-day world.

It's because it illustrates an important idea in good stories: when minor characters are developed beyond the level of faceless mooks or stock tropes, when they become interesting enough that you want to know more about them, the entire world and story become a lot richer.

So the receptionist in the waiting room for the dead is this vividly colored character below; the guy selling you a horse has one eye, swears like a sailor, and has very strong opinions about his neighbor's butcher shop. 

Note that these details were trivial to create; I've literally assembled tables of random personal characteristics, just to stimulate the imagination. (The great thing about an RPG is that if the side character proved interesting enough that it attracts the players' attention, you can then move them more and more front and center, and add nuance as needed; the cycle time of movies makes that not work as well there)

And seriously, an office comedy about the waiting room for the recently deceased in Beetlejuice? I would totally watch that movie.___

What happens when an engineer has a mechanically failing heart? The engineer comes up with a fix, of course. In this case, the traditional duct tape was replaced with a material more suitable for surgical implantation, but the idea remains the same.

I've always suspected that a mechanical engineering degree might be beneficial to surgeons.

As the heart pumps blood around the body, the aorta - the main vessel from the heart- stretches to accommodate the blood-flow. In most people it relaxes back to normal size, but for people with Marfan syndrome it can fail to recover, gradually enlarging over time.

From an early age Mr Golesworthy was fully aware he was living with the risk his aorta could one day stretch so much it would burst. And during a regular check-up in 2000 he was told the time had come to consider pre-emptive surgery.

But he was "unimpressed" with the options available to him. Traditional surgery is lengthy and complex and includes replacing the stretched segment of the aorta with an artificial graft. Sometimes surgeons also have to put metal valves inside the heart to replace ones that are cut out.

So he engineered himself a solution.

His thinking was straight-forward.

He says: "If the hose-pipe is bulging, I must get some insulation tape and wrap it round the outside of the hose-pipe to stop it bulging.

"It's that crude and simple, and we have all done it in our gardens."___What happens when an engineer has a mechanically failing heart? The engineer comes up with a fix, of course.

This telescope is far from derelict: 52 years after its completion, the Arecibo Observatory remains the world's largest single-aperture telescope, a 1000-foot dish that scans the heavens in radio frequencies. These very red colors of light -- beyond infrared or microwave -- contain many of the key visual "fingerprints" we use to identify the chemical composition of distant stars.

But sitting, as it does, in the middle of the Puerto Rican forest, it steadily acquires a patina, and is often shrouded in mist, giving it the appearance of an artifact from an ancient technological civilization. It's hard not to imagine early hominids stepping out of the trees and staring, fascinated, at it, wondering what force could have made this thing.

Arecibo is far from alone in this regard: the best place to put most kinds of telescope is far from cities. Apart from radio telescopes, which work in frequencies of light to which the atmosphere is fairly transparent, it's often important to put them on high mountains in the open desert as well, to minimize atmospheric distortion, or sometimes in locations that optimize viewing angle. This tends to result in a combination of high drama and exotic locations: the GTC, perched on a high rock in the Canary Islands; Keck, on top of Mauna Kea; the VLT, in the middle of the Atacama Desert; or the SPT solar observatory, located at the South Pole. (Where I almost ended up getting stationed once)

So for your enjoyment today, some pictures of the tools that do science.

In the category of extremely bizarre life forms, this one is definitely one of the stranger-looking. Discussions on the Internet suggest that this is a type of ribbon worm called a Gorgonorhynchus, and the white thing it is ejecting is an unusual proboscis -- a branching feeding tube.

From looking at the video (https://youtu.be/znaW_6NMwxE), it seems to me that its mouth detaches from the white stuff almost as soon as it has been ejected, which would suggest that it's something quite other. 

So I'm going to file this under "I'm not sure exactly what this is, although the 1932 paper linked does sound at least somewhat like it, and this is pretty damned weird and kind of wonderful to watch."

The Gorgonorhynchus
So the strange white thing that seems to “erupt” from the worm is its proboscis. This is a tubular sucking organ that some worms use to feed.
During eversion, which takes place almost explosively, the short main trunk first appears, then this divides and the finer and filter branches appear, but since each one of these is the result of an evagination the effect is almost indescribable. It is as if a large number of lively, wriggling, minute worms had been shot out.

A significant new feature launch for Google+ today! We've been playing with Collections behind the scenes a lot, and they've proven a lot of fun and a great way to share your stuff. Collections can be private or public, and in our internal testing I've found them incredibly liberating: you feel that you can post much more about a single subject when you've got a single "magazine" for it.

One of the important things to know about Collections is that you can set a collection to either be automatically followed by anyone who follows your profile (i.e., it basically is a way to label parts of your profile, although people can also subscribe to just that) or not (i.e., it's a separate channel that you can run). Collections do the first by default, which means you can create new collections and keep all your readership -- and if readers don't want some particular... more »

Introducing Google+ Collections, a new way to group your posts by topic

Our happiest Google+ users are those who connect with others around shared interests and passions. So we set out to give people a place to express the things they love. Today, we’re announcing Google+ Collections, a new way to group your posts by topic.

Every collection is a focused set of posts on a particular topic, providing an easy way for you to organize all the things you’re into. Each collection can be shared publicly, privately, or with a custom set of people. Once you create your first collection, your profile will display a new tab where other people can find and follow your collections.

Posts in collections you follow will appear in your Home stream, with a link to easily jump right into the collection so you can get to similar content from that author. Collections give you a great way to find more of the stuff you love from the people you follow.

Collections is available on Android and the web, and iOS is coming later. For Android users, make sure to update your Google+ app to get access to Collections.

For inspiration on interesting topics, check out our Featured Collections page here: g.co/collections

I recommend you play around with these. I've found that for myself, at least, a small number of collections really represented what I write, and I'm going to try organizing all of my content that way to see how it goes. 

In my case, those are:
Today I Learned: https://plus.google.com/collection/ktW_P -- science, history, math, engineering, or any other interesting thing to broaden your world.
Politics, Society & the Law: https://plus.google.com/collection/ME_wZ -- the news, the law, and the changes affecting our world.
Brief Dispatches: https://plus.google.com/collection/kM0AX -- a miscellanea of art, science, and my rather odd sense of humor.
Google Updates: https://plus.google.com/collection/AL0mb -- you're seeing it now!

That's about the best description I can give of this musical instrument.

Continuing the subject of "sex work as work:" there's an extraordinary thread on /r/AskReddit that asked: "Current or former sex workers, what is your opinion of your customers?" And this is a thread worth reading. You'll find in it a huge variety of stories; people who came to different kinds of sex work from different places, and had different experiences. If you want to see what the real variety of people's experience is, this is a great place to start.

The thread is not NSFW, by the way. It deals with mature topics -- sex, life, loss -- and is "adult" in the sense that it discusses things with real maturity and depth.

There are a lot of stories here that are going to hit you hard emotionally, but probably not in the ways you would expect. Lots of stories of particular customers that stand out in people's heads, who they were and what it... more »

There are a lot of stories here that are going to hit you hard emotionally, but probably not in the ways you would expect. Lots of stories of particular customers that stand out in people's heads, who they were and what it was about them that made them special.

So here's a post for you that straddles the line between my normal threads of politics, society and the law on the one hand, and how things are made on the other: a chance to see sex work through the eyes of people who do it. And like any explanation worth a damn, it doesn't have any summary that will fit on a bumper sticker.

Milestones in Engineering: Today +Samantha Cristoforetti brewed the first espresso in space, and drank it while sitting in the cupola of the ISS.

I think I need a better morning coffee routine. 

This morning aboard the International Space Station, European Space Agency astronaut Samantha Cristoforetti brewed the first espresso ever in space. After, she enjoyed the beverage viewing Earth from the station's cupola and wrote, "Coffee: the finest organic suspension ever devised. Fresh espresso in the new Zero-G cup! To boldly brew..."

Read why brews served in microgravity will percolate better science than coffee, thanks to the Space Cup: http://go.nasa.gov/1E7n8NA

I can barely imagine what this experience must have been like for the riders of the day: one of the original "dark rides" (amusement park rides that take place in a dark space so they can move you through settings and create the experience of a trip; Disneyland made them a centerpiece, five decades later), and by any account one of the grandest.

Interesting side note: after the exhibition, the amusement park built around this was named "Luna Park." To this day, that's the generic term for an amusement park in Hebrew.

In 1901, you could pay 50 cents to ride an airship to the Moon

This article by Ron Miller is so cool I'm just going to quote some:

The passengers wait eagerly in the ornate lobby of the enormous spaceport. Soon, a signal indicates that their spaceship is ready for boarding. As they wait, special displays instruct them about how their spaceship functions and what to expect once they leave Earth's atmosphere. Aboard the giant spacecraft — as luxuriously appointed as any yacht — they are soon on their way to a vacation on the Moon.

No, this isn't a vision of the future of space tourism. It's what happened in 1901, when people could pay a princely half dollar for a ticket to ride into space.

[...]

Thompson spared no expense in creating the illusion of a trip to the Moon. To house his show, he erected an eighty-foot-high, 40,000-square-foot building that for sheer opulence put European opera houses to shame. It cost a staggering $84,000 to construct... at a time when a comfortable home could be built for $2000.

For fifty cents — twice the price of any other attraction on the midway, such as the ever-popular "Upside-Down House" — customers of "Thompson's Aerial Navigation Company" took a trip to the moon on a thirty-seat spaceship named "Luna". The spaceship resembled a cross between a dirigible and an excursion steamer, with the addition of enormous red canvas wings that flapped like a bird's. The wings were worked by a system of pulleys and the sensation of wind was created by hidden fans. A series of moving canvas backdrops provided the effect of clouds passing by and the earth dropping into the distance. Lighting and sound effects added to the illusion.

[...]

Every half hour, at the sound of a gong and the rattle of anchor chain, the "Luna" — "a fine steel airship of the latest pattern", according to one newspaper — rocked from side to side and then rose into the sky under the power of its beating wings. The passengers, sitting on steamer chairs, see clouds floating by, then a model of Buffalo far below, complete with the exposition itself and its hundreds of blinking lights. The city soon falls into the distance as the entire planet earth comes into view. Soon, the ship is surrounded the twinkling stars of outer space. After surviving a terrific — and spectacular — electrical storm the "Luna" and its passengers sets down in a lunar crater.

Read the whole thing here, and look at pictures:

Ethiopia makes surprisingly good beers, especially darker ones. They tend towards the maltier, maybe a bit sweeter side, but I haven't been disappointed yet... except when the local restaurant is out. This one and a dark stout named Hakim are my two favorites so far.

Confectionery and taxidermy: a beautiful, and (in many senses) visceral pleasure. These really look beautiful; I would have trouble convincing myself to eat them, they're so finely made.

A warning: the cover image is, perhaps, the least bizarre of the ones featured in the article.
