Social software: 5 properties & 3 dynamics

business, history, politics, security, social software, tech in changing society / /

From danah boyd’s “Social Media is Here to Stay… Now What?” at the Microsoft Research Tech Fest, Redmond, Washington (danah: 26 February 2009):

Certain properties are core to social media in a combination that alters how people engage with one another. I want to discuss five properties of social media and three dynamics. These are the crux of what makes the phenomena we’re seeing so different from unmediated phenomena.

A great deal of sociality is about engaging with publics, but we take for granted certain structural aspects of those publics. Certain properties are core to social media in a combination that alters how people engage with one another. I want to discuss five properties of social media and three dynamics. These are the crux of what makes the phenomena we’re seeing so different from unmediated phenomena.

1. Persistence. What you say sticks around. This is great for asynchronicity, not so great when everything you’ve ever said has gone down on your permanent record. …

2. Replicability. You can copy and paste a conversation from one medium to another, adding to the persistent nature of it. This is great for being able to share information, but it is also at the crux of rumor-spreading. Worse: while you can replicate a conversation, it’s much easier to alter what’s been said than to confirm that it’s an accurate portrayal of the original conversation.

3. Searchability. My mother would’ve loved to scream search into the air and figure out where I’d run off with friends. She couldn’t; I’m quite thankful. But with social media, it’s quite easy to track someone down or to find someone as a result of searching for content. Search changes the landscape, making information available at our fingertips. This is great in some circumstances, but when trying to avoid those who hold power over you, it may be less than ideal.

4. Scalability. Social media scales things in new ways. Conversations that were intended for just a friend or two might spiral out of control and scale to the entire school or, if it is especially embarrassing, the whole world. …

5. (de)locatability. With the mobile, you are dislocated from any particular point in space, but at the same time, location-based technologies make location much more relevant. This paradox means that we are simultaneously more and less connected to physical space.

Those five properties are intertwined, but their implications have to do with the ways in which they alter social dynamics. Let’s look at three different dynamics that have been reconfigured as a result of social media.

1. Invisible Audiences. We are used to being able to assess the people around us when we’re speaking. We adjust what we’re saying to account for the audience. Social media introduces all sorts of invisible audiences. There are lurkers who are present at the moment but whom we cannot see, but there are also visitors who access our content at a later date or in a different environment than where we first produced them. As a result, we are having to present ourselves and communicate without fully understanding the potential or actual audience. The potential invisible audiences can be stifling. Of course, there’s plenty of room to put your head in the sand and pretend like those people don’t really exist.

2. Collapsed Contexts. Connected to this is the collapsing of contexts. In choosing what to say when, we account for both the audience and the context more generally. Some behaviors are appropriate in one context but not another, in front of one audience but not others. Social media brings all of these contexts crashing into one another and it’s often difficult to figure out what’s appropriate, let alone what can be understood.

3. Blurring of Public and Private. Finally, there’s the blurring of public and private. These distinctions are normally structured around audience and context with certain places or conversations being “public” or “private.” These distinctions are much harder to manage when you have to contend with the shifts in how the environment is organized.

All of this means that we’re forced to contend with a society in which things are being truly reconfigured. So what does this mean? As we are already starting to see, this creates all new questions about context and privacy, about our relationship to space and to the people around us.

The future of security

business, law, security, technology / /

From Bruce Schneier’s “Security in Ten Years” (Crypto-Gram: 15 December 2007):

Bruce Schneier: … The nature of the attacks will be different: the targets, tactics and results. Security is both a trade-off and an arms race, a balance between attacker and defender, and changes in technology upset that balance. Technology might make one particular tactic more effective, or one particular security technology cheaper and more ubiquitous. Or a new emergent application might become a favored target.

…

By 2017, people and organizations won’t be buying computers and connectivity the way they are today. The world will be dominated by telcos, large ISPs and systems integration companies, and computing will look a lot like a utility. Companies will be selling services, not products: email services, application services, entertainment services. We’re starting to see this trend today, and it’s going to take off in the next 10 years. Where this affects security is that by 2017, people and organizations won’t have a lot of control over their security. Everything will be handled at the ISPs and in the backbone. The free-wheeling days of general-use PCs will be largely over. Think of the iPhone model: You get what Apple decides to give you, and if you try to hack your phone, they can disable it remotely. We techie geeks won’t like it, but it’s the future. The Internet is all about commerce, and commerce won’t survive any other way.

Marcus Ranum: … Another trend I see getting worse is government IT know-how. At the rate outsourcing has been brain-draining the federal workforce, by 2017 there won’t be a single government employee who knows how to do anything with a computer except run PowerPoint and Web surf. Joking aside, the result is that the government’s critical infrastructure will be almost entirely managed from the outside. The strategic implications of such a shift have scared me for a long time; it amounts to a loss of control over data, resources and communications.

Bruce Schneier: … I’m reminded of the post-9/11 anti-terrorist hysteria — we’ve confused security with control, and instead of building systems for real security, we’re building systems of control. Think of ID checks everywhere, the no-fly list, warrantless eavesdropping, broad surveillance, data mining, and all the systems to check up on scuba divers, private pilots, peace activists and other groups of people. These give us negligible security, but put a whole lot of control in the government’s hands.

…

That’s the problem with any system that relies on control: Once you figure out how to hack the control system, you’re pretty much golden. So instead of a zillion pesky worms, by 2017 we’re going to see fewer but worse super worms that sail past our defenses.

From Dave Alan’s “Interview with Alex Christopher” (Leading Edge Research Group: 1 June 1996):

Legend: DA [Dave Alan, Host] AC: [Alex Christopher] C: [Caller]

…

(Note: according to former British Intelligence agent Dr. John Coleman, the London-based Wicca Mason lodges are one-third of the overall global conspiracy. The other two thirds are the Black Nobility banking families who claim direct descent from the early Roman emperors, and also the Maltese Jesuits or the Jesuit – Knights of Malta network. All three networks each have 13 representatives within the Bilderberg organization, which is a cover for the Bavarian Illuminati, suggestive that Bavaria itself has orchestrated a “marriage of convenience” between these three formerly competitive global control groups. – Branton)

…

AC: All right. The information, primarily, that is in “Pandora’s Box” covers how the major corporations, railroad and banking concerns in this country were set up through a ‘trust’ that was originally known as the Virginia Company… The deal was that everything would remain under English control, or subservient to it, and that brings us right up to today, because we are still looking at everything falling under that ‘trust’ system going back to the Crown of England. It is mind boggling to think that everyone in this country has been led to believe that the people in the United States had won independence from England, when in fact they never did.

…

AC: The capstone, or the dedication stone, for the Denver airport has a Masonic symbol on it. A whole group of us went out to the airport to see some friends off and see this capstone, which also has a time capsule imbedded inside it. It sits at the south eastern side of the terminal which, by the way, is called “The Great Hall”, which is what Masons refer to as their meeting hall. And, on this thing it mentions “the New World Airport Commission”. …

AC: It has a Masonic symbol on it, and it also has very unusual geometric designs. It depicts an arm rising up out of it that curves at a 45 degree angle. It also has a thing that looks like a keypad on it. This capstone structure is made of carved granite and stainless steel, and it is very fancy.. This little keypad area at the end of the arm has an out-of-place unfinished wooden block sitting on it. The gentleman that was with me on the first trip out to the airport has since died. They say he committed suicide, but everything else tells me that this is not possible. No one can double-tie a catheter behind his own neck and strangle himself. I just don’t think that is possible. But, his name was Phil Schneider, and he started blowing the whistle on all this stuff going on in the underground bases that he had helped build for years and years. He worked on the underground bases at Area 51 and Dulce, New Mexico, as well as several other places. Schneider told me that this keypad-looking area looked like a form of techno-geometry that is “alien-oriented”, and that it had something to do with a “directional system”, whatever that meant, that functioned as a homing beacon to bring ships right into the “Great Hall”.

…

(Note: … Remember even through the Bilderbergers consist of a “marriage of convenience” between Londonese Wicca Masons, Basilian Black Nobility and Roman Maltese Jesuits… the supreme controllers of the Bildeberger cult itself are the secret black Gnostic cults of Bavaria whose ‘Cult of the Serpent’ — or Illuminati — can be traced back to Egypt and ultimately to Babylon itself. These Rockefeller-Nazi projects reportedly continued through at least 1975 during which period many thousands more “underground Nazis” were brought into America from Europe and also, if we are to believe some reports, from the secret German “New Berlin” base under the mountains of Neu Schwabenland, Antarctica that was established during World War II via Nazi-occupied South Africa. Is Neu Schwabenland the REAL power behind the joint Bavarian-Alien New World Order Agenda? …)

…

AC: … It took myself and two other people over eight months to figure out all the symbology that is embodied in these murals. It turned out that some of these are ‘trigger’ pictures, containing symbology designed to trigger altered personalities of people that have been groomed in MKULTRA type programs for specific tasks that they have been trained to do in terms of something connected with Satanic rituals and mind control. I had one woman that called me out of the blue one night, and she was really disturbed about some information. She told me many different things that later turned out to be known MKULTRA triggers. Also, almost every aspect of these murals contains symbols relating back to secret societies. When you get the overall view of what they are talking about in these things, it is very very scary. It goes back to the Bio-diversity Treaty, getting rid of specific races of people, taking over the world and mind control.

…

AC: Well, the gentleman that I was dealing with, Phil Schneider, said that during the last year of construction they were connecting the underground airport system to the deep underground base. He told me that there was at least an eight-level deep underground base there, and that there was a 4.5 square mile underground city and an 88.5 square-mile base underneath the airport.

…

DA: You were telling me that there are huge concrete corridors with sprinklers all along the ceiling. What are these sprinkler heads doing in a concrete bunker, pray tell? (Presumably concrete will not ‘burn’ if there is a potential fire, so is it possible that something other than ‘water’ is meant to be expelled from these sprinklers which are located “all along” the ceiling? – Branton)

…

AC: I think a lot of the people saw things that disturbed them so much that they would not talk about it. I know several people who worked on the project that managed to find their way down into the depths, probably close to the deep underground base, and saw things that scared them so badly they won’t talk about it. I interviewed a few of the former employees on these construction crews that worked out there on these buildings that ended up buried, and they are afraid to talk. They say that everybody is real nervous about it, and they decided to tell some of the secrets that they knew, but they don’t want anybody to know who they are. So, I can tell you that it is a very unusual and spooky type of place, and if you are a sensitive person you get nauseated as soon as you enter the perimeter of the airport. Especially when you go down underground. You become very nauseated a nervous. There is also so much electromagnetic flux in the area that if you get out on the open ground around the airport, you will ‘buzz’.

…

AC: If Phil is right, and all this hooks up to the deep underground base that he was offered the plans to build back in 1979, and that what this other man TOLD me in private [is] that there is a lot of human SLAVE LABOR in these deep underground bases being used by these aliens, and that a lot of this slave labor is children. HE SAID that when the children reach the point that they are unable to work any more, they are slaughtered on the spot and consumed.

DA: Consumed by who?

AC: Aliens. Again, this is not from me, but from a man that gave his life to get this information out. He worked down there for close to 20 years, and he knew everything that was going on.

DA: Hmmm. Who do these aliens eat?

AC: They specifically like young human children, that haven’t been contaminated like adults. Well, there is a gentleman out giving a lot of information from a source he gets it from, and he says that there is an incredible number of children snatched in this country.

DA: Over 200,000 each year.

AC: And that these children are the main entree for dinner.

…

AC: Yes. From some information that has been put out by a group or team that also works in these underground bases that is trying to get information out to people that love this country, THERE IS A WAR THAT IS GOING ON UNDER OUT FEET, AND ABOVE OUR HEADS, that the public doesn’t know anything about, and its between these ALIEN forces and the HUMANS that are trying to fight them.

DA: What other types have you seen?

AC: The ones that I have seen are the big-eyed Greys and the Reptilians.

DA: What do these Reptilians look like?

AC: There are three different types.

…

AC: … Anyway, they were both totally flipped out. I finally got them calmed down enough to let me go home. I went home and went to bed. The next thing I know, I woke up and there is this ‘thing’ standing over my bed. He had wrap-around yellow eyes with snake pupils, and pointed ears and a grin that wrapped around his head. He had a silvery suit on, and this scared the living daylights out of me. I threw the covers over my head and started screaming….I mean, here is this thing with a Cheshire-cat grin and these funky glowing eyes…this is too much. I have seen that kind of being on more than one occasion.

DA: What else can you say about it?

AC: Well, he had a hooked nose and he was [humanoid] looking, other than the eyes, and had kind of grayish skin. Later on in 1991, I was working in a building in a large city, and I had taken a break about 6:00, and the next thing I knew it was 10:30 at night, and I thought I had taken a short break. I started remembering that I was taken aboard a ship, through four floors of an office building, and through a roof. There on the ship is were I encountered ‘GERMANS’ AND ‘AMERICANS’ WORKING TOGETHER, and also the GREY ALIENS, and then we were taken to some other kind of facility and there I saw the REPTILIANS again … the one’s I call the “baby Godzilla’s”, that have the short teeth and yellow slanted eyes, and who look like a VELOCI-RAPTOR, kind of.

DA: So, why would these people pick on you?

AC: Well, I found one common denominator in the abduction, and it keeps on being repeated over and over again. I deal with lots of people who have been abducted, and the one common denominator seems to be the blood line, and its the blood line that goes back to ancient Indian or Native American blood lines.

…

AC: Well, at that facility I saw the almond-eyed Greys, but the thing that sticks in my mind are the beings that look like reptiles, or the veloci-raptors. They are the cruelest beings you could ever imagine, and they even smell hideous. There were a couple of very unusual areas down there where I was taken which looked like cold storage lockers, where these things were in hibernation tubes, and that is about all I remember, other than seeing some black helicopters and little round-wing disk type aircraft

…

In the book “Cosmic Conflict”, the author talks about the ancient city that was uncovered by the Germans before World War II, and tells about their effort to revive some frozen humans they found in this underground city, and that the true humans couldn’t be revived, but the ones that could be revived were in fact reptilians in disguise, and the reptilians have the capability to do shape-shifting and create a [laser] holographic image so when you look at them you see a human, but under that there is no human there. … Allegedly the reptilians re-animated and killed the Soviet scientists and through some type of psychic osmosis drained their minds and assimilated their memories and features through a molecular shape-shifting type process. … The alien ‘impostors’ then called for backup and more scientists came out and were ‘replaced’, and these eventually returned to Russia and began to infiltrate the Communist government.

…

AC: These people that have done all this research and are part of the underground government are telling that the humans on this planet have been at war with these reptilian aliens for thousands of years. At one point, things got so hot on the planet, like it is now, aliens took on this holographic image and infiltrated the human race in order to take it over and undermine it, just like this New World Order is doing right now. They’re saying that the same thing happened to civilization on Earth before, and that the humans before actually had the capability for interplanetary travel, and that it was so bad here with the reptilians that they had to leave… What they are also saying is that these beings that are human-looking that are visiting our planet, at this time, trying to inform people what is going on, and guide them, are actually OUR ANCESTORS THAT ESCAPED FROM EARTH before, when it was under reptilian domination.

…

AC: I went to South Florida a couple of weeks ago and interviewed a man who had done research for 30 years, and oddly enough, he tapped into some of the same information I had, in that our government has had round-winged, saucer-type technology, high mach speed aircraft since the 1920’s, and that in 1952 they had over 500 of these aircraft hidden in secret bases. Now, if they had that in 1952, considering that military technology grows by 44 years for every year that goes by, what do you imagine they have now, 44 years later, after technology has advanced the equivalent of 1,936 years?

…

AC: He claims to be one of the ones who jumped overboard off the Eldridge when it went into hyperspace during the Philadelphia Experiment. He actually traveled forward in time, and asked the people that he encountered there what happened in his future. At that time, he was given the information about the New World Order and that Denver was the location for the NWO Western Sector, and that Atlanta was supposed to be the control center for the Eastern Sector. Can it be that the fact that the Olympics is supposed to be in Atlanta is part of a scenario?

A Russian man with perfect memory

history, science / /

From Jonah Lehrer’s “Hell is a Perfect Memory” (The Frontal Cortex: 2 December 2008):

This isn’t the first case report of a person with perfect memory. In the masterful The Mind of A Mnemonist, the Soviet neurologist A.R. Luria documented the story of a Russian newspaper reporter, D.C. Shereshevskii, who was incapable of forgetting. For example, D.C. would be bound by his brain to memorize the entire Divine Comedy of Dante after a single reading. Audiences would scream out random numbers 100 digits long and he would effortlessly recount them. The only requirement of this man’s insatiable memory was that he be given 3 or 4 seconds to visualize each item during the learning process. These images came to D.C. automatically.

Eventually, D.C.’s memory overwhelmed him. He. struggled with mental tasks normal people find easy. When he read a novel, he would instantly memorize every word by heart, but miss the entire plot. Metaphors and poetry – though they clung to his brain like Velcro – were incomprehensible. He couldn’t even use the phone because he found it hard to recognize a person’s voice “when it changes its intonation…and it does that 20 or 30 times a day.”

A woman who never forgets anything

history, science / /

From Samiha Shafy’s “An Infinite Loop in the Brain” (Der Spiegel: 21 November 2008):

Price can rattle off, without hesitation, what she saw and heard on almost any given date. She remembers many early childhood experiences and most of the days between the ages of 9 and 15. After that, there are virtually no gaps in her memory. “Starting on Feb. 5, 1980, I remember everything. That was a Tuesday.”

…

“People say to me: Oh, how fascinating, it must be a treat to have a perfect memory,” she says. Her lips twist into a thin smile. “But it’s also agonizing.”

In addition to good memories, every angry word, every mistake, every disappointment, every shock and every moment of pain goes unforgotten. Time heals no wounds for Price. “I don’t look back at the past with any distance. It’s more like experiencing everything over and over again, and those memories trigger exactly the same emotions in me. It’s like an endless, chaotic film that can completely overpower me. And there’s no stop button.”

She’s constantly bombarded with fragments of memories, exposed to an automatic and uncontrollable process that behaves like an infinite loop in a computer. Sometimes there are external triggers, like a certain smell, song or word. But often her memories return by themselves. Beautiful, horrific, important or banal scenes rush across her wildly chaotic “internal monitor,” sometimes displacing the present. “All of this is incredibly exhausting,” says Price.

…

The scientists were able to verify her autobiographical data because she has meticulously kept a diary since the age of 10. She has filled more than 50,000 pages with tiny writing, documenting every occurrence, no matter how insignificant. Writing things down helps Price organize the thoughts and images shimmering in her head.

In fact, she feels a strong need to document her life. This includes hoarding every possible memento from childhood, including dolls, stuffed animals, cassette tapes, books, a drawer from dresser she had when she was five. “I have to be able to touch my memories,” Price explains.

[James McGaugh, founder of the Center for the Neurobiology of Learning and Memory at the University of California in Irvine,] and his colleagues concluded that Price’s episodic memory, her recollection of personal experiences and the emotions associated with them, is virtually perfect. A case like this has never been described in the history of memory research, according to McGaugh. He explains that Price differs substantially from other people with special powers of recall, such as autistic savants, because she uses no strategies to help her remember and even does a surprisingly poor job on some memory tests.

It’s difficult for her to memorize poems or series of numbers — which helps explain why she never stood out in school. Her semantic memory, the ability to remember facts not directly related to everyday life, is only average.

Two years ago, the scientists published their first conclusions in a professional journal without revealing the identity of their subject. Since then, more than 200 people have contacted McGaugh, all claiming to have an equally perfect episodic memory. Most of them were exposed as fakes. Three did appear to have similarly astonishing abilities. “Their personalities are very different. The others are not as anxious as Jill. But they achieve comparable results in the tests,” McGaugh reports.

The subjects do have certain compulsive traits in common, says McGaugh, especially compulsive hoarding. The three others are left-handed, and Price also showed a tendency toward left-handedness in tests.

…

In neurobiological terms, a memory is a stored pattern of links between nerve cells in the brain. It is created when synapses in a network of neurons are activated for a short time. The more often the memory is recalled afterwards, the more likely it is that permanent links develop between the nerve cells — and the pattern will be stored as a long-term memory. In theory there are so many possible links that an almost unlimited number of memories can be permanently stored.

So why don’t all people have the same powers of recollection as Jill Price? “If we could remember everything equally well, the brain would be hopelessly overburdened and would operate more slowly,” says McGaugh. He says forgetting is a necessary condition of having a viable memory — except in the case of Price and the other three memory superstars.

Luddites and e-books

business, history, on writing, tech in changing society / /

From Clay Shirky’s “The Siren Song of Luddism” (Britannica Blog: 19 June 2007):

…any technology that fixes a problem … threatens the people who profit from the previous inefficiency. However, Gorman omits mentioning the Luddite response: an attempt to halt the spread of mechanical looms which, though beneficial to the general populace, threatened the livelihoods of King Ludd’s band.

… printing was itself enormously disruptive, and many people wanted veto power over its spread as well. Indeed, one of the great Luddites of history (if we can apply the label anachronistically) was Johannes Trithemius, who argued in the late 1400s that the printing revolution be contained, in order to shield scribes from adverse effects.

…

The uncomfortable fact is that the advantages of paper have become decoupled from the advantages of publishing; a big part of preference for reading on paper is expressed by hitting the print button. As we know from Lyman and Varian’s “How Much Information?” study, “the vast majority of original information on paper is produced by individuals in office documents and postal mail, not in formally published titles such as books, newspapers and journals.”

…

The problems with e-books are that they are not radical enough: they dispense with the best aspect of books (paper as a display medium) while simultaneously aiming to disable the best aspects of electronic data (sharability, copyability, searchability, editability.)

…

If we gathered every bit of output from traditional publishers, we could line them up in order of vulnerability to digital evanescence. Reference works were the first to go — phone books, dictionaries, and thesauri have largely gone digital; the encyclopedia is going, as are scholarly journals. Last to go will be novels — it will be some time before anyone reads One Hundred Years of Solitude in any format other than a traditionally printed book. Some time, however, is not forever. The old institutions, and especially publishers and libraries, have been forced to use paper not just for display, for which is it well suited, but also for storage, transport, and categorization, things for which paper is completely terrible. We are now able to recover from those disadvantages, though only by transforming the institutions organized around the older assumptions.

Matching voters with their votes, thanks to voting machines

politics, security, tech in changing society / /

From Declan McCullagh’s “E-voting predicament: Not-so-secret ballots” (CNET News: 20 August 2007):

Two Ohio activists have discovered that e-voting machines made by Election Systems and Software and used across the country produce time-stamped paper trails that permit the reconstruction of an election’s results — including allowing voter names to be matched to their actual votes.

…

Ohio law permits anyone to walk into a county election office and obtain two crucial documents: a list of voters in the order they voted, and a time-stamped list of the actual votes. “We simply take the two pieces of paper together, merge them, and then we have which voter voted and in which way,” said James Moyer, a longtime privacy activist and poll worker who lives in Columbus, Ohio.

Once the two documents are merged, it’s easy enough to say that the first voter who signed in is very likely going to be responsible for the first vote cast, and so on.

…

Other suppliers of electronic voting machines say they do not include time stamps in their products that provide voter-verified paper audit trails. Sequoia Voting Systems and Hart Intercivic both said they don’t. A spokesman for Diebold Election Systems (now Premier Election Solutions), said they don’t for security and privacy reasons…

…

David Wagner, a professor of computer science at the University of California, Berkeley, said electronic storage of votes in the order that voters cast them is a recurring problem with e-voting machines.

“This summer I learned that Diebold’s AV-TSX touchscreen voting machine stores a time stamp showing the time which each vote was cast–down to the millisecond–along with the electronic record of that vote,” Wagner said in an e-mail message. “In particular, we discovered this as part of the California top-to-bottom review and reported it in our public report on the Diebold voting system. However, I had no idea that this kind of information was available to the public as a public record.”

10,000 hours to reach expertise

art, education, science / /

From Malcolm Gladwell’s “A gift or hard graft?” (The Guardian: 15 November 2008):

This idea – that excellence at a complex task requires a critical, minimum level of practice – surfaces again and again in studies of expertise. In fact, researchers have settled on what they believe is a magic number for true expertise: 10,000 hours.

“In study after study, of composers, basketball players, fiction writers, ice-skaters, concert pianists, chess players, master criminals,” writes the neurologist Daniel Levitin, “this number comes up again and again. Ten thousand hours is equivalent to roughly three hours a day, or 20 hours a week, of practice over 10 years… No one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.”

Spimes, objects trackable in space and time

business, security, social software, tech in changing society, technology / /

From Bruce Sterling’s “Viridian Note 00459: Emerging Technology 2006” (The Viridian Design Movement: March 2006):

When it comes to remote technical eventualities, you don’t want to freeze the language too early. Instead, you need some empirical evidence on the ground, some working prototypes, something commercial, governmental, academic or military…. Otherwise you are trying to freeze an emergent technology into the shape of today’s verbal descriptions. This prejudices people. It is bad attention economics. It limits their ability to find and understand the intrinsic advantages of the technology. …

If you look at today’s potent, influential computer technologies, say, Google, you’ve got something that looks Artificially Intelligent by the visionary standards of the 1960s. Google seems to “know” most everything about you and me, big brother: Google is like Colossus the Forbin Project. But Google is not designed or presented as a thinking machine. Google is not like Ask Jeeves or Microsoft Bob, which horribly pretend to think, and wouldn’t fool a five-year-old child. Google is a search engine. It’s a linking, ranking and sorting machine. …

Even if there’s like, Boolean logic going on here, this machine has got nothing to do with any actual thinking. This machine is clearly a big card shuffler. It’s a linker, a stacker and a sorter. …

In the past, they just didn’t get certain things. For instance:

1. the digital devices people carry around with them, such as laptops, media players, camera phones, PDAs.
2. wireless and wired local and global networks that serve people in various locations as they and their objects and possessions move about the world.
3. the global Internet and its socially-generated knowledge and Web-based, on-demand social applications.

This is a new technosocial substrate. It’s not about intelligence, yet it can change our relationship with physical objects in the three-dimensional physical world. Not because it’s inside some box trying to be smart, but because it’s right out in the world with us, in our hands and pockets and laps, linking and tracking and ranking and sorting.

Doing this work, in, I think, six important ways:

1. with interactive chips, objects can be labelled with unique identity – electronic barcoding or arphids, a tag that you can mark, sort, rank and shuffle.
2. with local and precise positioning systems – geolocative systems, sorting out where you are and where things are.
3. with powerful search engines – auto-googling objects, more sorting and shuffling.
4. with cradle to cradle recycling – sustainability, transparent production, sorting and shuffling the garbage.

Then there are two other new factors in the mix.

5. 3d virtual models of objects – virtual design – cad-cam, having things present as virtual objects in the network before they become physical objects.
6. rapid prototyping of objects – fabjects, blobjects, the ability to digitally manufacture real-world objects directly or almost directly from the digital plans.

If objects had these six qualities, then people would interact with objects in an unprecedented way, a way so strange and different that we’d think about it better if this class of object had its own name. I call an object like this a “spime,” because an object like this is trackable in space and time. …

“Spimes are manufactured objects whose informational support is so overwhelmingly extensive and rich that they are regarded as material instantiations of an immaterial system. Spimes begin and end as data. They’re virtual objects first and actual objects second.” …

“The primary advantage of an Internet of Things is that I no longer inventory my possessions inside my own head. They’re inventoried through an automagical inventory voodoo, work done far beneath my notice by a host of machines. So I no longer to bother to remember where I put things. Or where I found them. Or how much they cost. And so forth. I just ask. Then I am told with instant real-time accuracy. …

It’s [spimes] turning into what Julian Bleecker calls a “Theory Object,” which is an idea which is not just a mental idea or a word, but a cloud of associated commentary and data, that can be passed around from mouse to mouse, and linked-to. Every time I go to an event like this, the word “spime” grows as a Theory Object. A Theory Object is a concept that’s accreting attention, and generating visible, searchable, rankable, trackable trails of attention. …

It takes 10 years to develop expertise

business, commonplace book, education, teaching, technology / /

From Peter Norvig’s “Teach Yourself Programming in Ten Years” (2001):

Researchers ([John R. Hayes, Complete Problem Solver (Lawrence Erlbaum) 1989.], [Benjamin Bloom (ed.), Developing Talent in Young People (Ballantine) 1985.]) have shown it takes about ten years to develop expertise in any of a wide variety of areas, including chess playing, music composition, painting, piano playing, swimming, tennis, and research in neuropsychology and topology. There appear to be no real shortcuts: even Mozart, who was a musical prodigy at age 4, took 13 more years before he began to produce world-class music. In another genre, the Beatles seemed to burst onto the scene with a string of #1 hits and an appearance on the Ed Sullivan show in 1964. But they had been playing small clubs in Liverpool and Hamburg since 1957, and while they had mass appeal early on, their first great critical success, Sgt. Peppers, was released in 1967. Samuel Johnson thought it took longer than ten years: “Excellence in any department can be attained only by the labor of a lifetime; it is not to be purchased at a lesser price.” And Chaucer complained “the lyf so short, the craft so long to lerne.”

The birth of Geology & gradualism as a paradigm shift from catastrophism

history, religion, science, technology / /

From Kim Stanley Robinson’s “Imagining Abrupt Climate Change : Terraforming Earth” (Amazon Shorts: 31 July 2005):

This view, by the way, was in keeping with a larger and older paradigm called gradualism, the result of a dramatic and controversial paradigm shift of its own from the nineteenth century, one that is still a contested part of our culture wars, having to do with the birth of geology as a field, and its discovery of the immense age of the Earth. Before that, Earth’s history tended to be explained in a kind of Biblical paradigm, in which the Earth was understood to be several thousand years old, because of genealogies in the Bible, so that landscape features tended to be explained by events like Noah’s flood. This kind of “catastrophism” paradigm was what led Josiah Whitney to maintain that Yosemite Valley must have been formed by a cataclysmic earthquake, for instance; there simply hadn’t been time for water and ice to have carved something as hard as granite. It was John Muir who made the gradualist argument for glacial action over millions of years; and the eventual acceptance of his explanation was part of the general shift to gradualist explanations for Earth’s landforms, which also meant there was another time for evolution to have taken place. Gradualism also led by extension to thinking that the various climate regimes of the past had also come about fairly gradually.

Why did it take so long for blogging to take off?

From Paul Graham’s “Hiring is Obsolete” (May 2005):

Have you ever noticed that when animals are let out of cages, they don’t always realize at first that the door’s open? Often they have to be poked with a stick to get them out. Something similar happened with blogs. People could have been publishing online in 1995, and yet blogging has only really taken off in the last couple years. In 1995 we thought only professional writers were entitled to publish their ideas, and that anyone else who did was a crank. Now publishing online is becoming so popular that everyone wants to do it, even print journalists. But blogging has not taken off recently because of any technical innovation; it just took eight years for everyone to realize the cage was open.

The math behind Flash Worms

science, security, tech in changing society, technology / /

From Stuart Staniford, David Moore, Vern Paxson, & Nicholas Weaver’s “The Top Speed of Flash Worms” [PDF] (29 October 2004):

Flash worms follow a precomputed spread tree using prior knowledge of all systems vulnerable to the worm’s exploit. In previous work we suggested that a flash worm could saturate one million vulnerable hosts on the Internet in under 30 seconds [18]. We grossly over-estimated.

In this paper, we revisit the problem in the context of single packet UDP worms (inspired by Slammer and Witty). Simulating a flash version of Slammer, calibrated by current Internet latency measurements and observed worm packet delivery rates, we show that a worm could saturate 95% of one million vulnerable hosts on the Internet in 510 milliseconds. A similar worm using a TCP based service could 95% saturate in 1.3 seconds. …

Since Code Red in July 2001 [11], worms have been of great interest in the security research community. This is because worms can spread so fast that existing signature-based anti-virus and intrusion-prevention defenses risk being irrelevant; signatures cannot be manually generated fast enough …

The premise of a flash worm is that a worm releaser has somehow acquired a list of vulnerable addresses, perhaps by stealthy scanning of the target address space or perhaps by obtaining a database of parties to the vulnerable protocol. The worm releaser, in advance, computes an efficient spread tree and encodes it in the worm. This allows the worm to be far more efficient than a scan- ning worm; it does not make large numbers of wild guesses for every successful infection. Instead, it successfully infects on most attempts. This makes it less vulnerable to containment defenses based on looking for missed connections [7, 16, 24], or too many connections [20, 25]. …

A difficulty for the flash worm releaser is a lack of robustness if the list of vulnerable addresses is imperfect. Since it is assembled in advance, and networks constantly change, the list is likely to be more-or-less out of date by the time of use. This has two effects. Firstly, a certain proportion of actually vulnerable and reachable machines may not be on the list, thus preventing the worm from saturating as fully as otherwise possible. More seriously, some ad- dresses on the list may not be vulnerable. If such nodes are near the base of the spread tree, they may prevent large numbers of vulnerable machines from being infected by the worm. Very deep spread trees are particularly prone to this. Thus in thinking about flash worms, we need to explore the issue of robustness as well as speed. …

The Slammer worm [10, 22] of January 2003 was the fastest scanning worm to date by far and is likely close to the lower bound on the size of a worm. Data on observed Slammer infections (and on those of the similar Witty worm) provide us with estimates for packet rate and minimum code size in future flash worms. Slammer infected Microsoft’s SQL server. A single UDP packet served as exploit and worm and required no acknowledgment. The size of the data was 376 bytes, giving a 404 byte IP packet. This consisted of the following sections:

• IP header
• UDP header
• Data to overflow buffer and gain control
• Code to find the addresses of needed functions.
• Code to initialize a UDP socket
• Code to seed the pseudo-random number generator
• Code to generate a random address
• Code to copy the worm to the address via the socket …

In this paper, we assume that the target vulnerable population is N = 1000000 (one million hosts-somewhat larger than the 360, 000 infected by Code Red [11]). Thus in much less than a sec- ond, the initial host can directly infect a first generation of roughly 5,000 – 50,000 intermediate nodes, leaving each of those with only 20-200 hosts to infect to saturate the population. There would be no need for a third layer in the tree.

This implies that the address list for the intermediate hosts can fit in the same packet as the worm; 200 addresses only consumes 800 bytes. A flash version of Slammer need only be slightly different than the original: the address list of nodes to be infected would be carried immediately after the end of the code, and the final loop could traverse that list sending out packets to infect it (instead of generating pseudo-random addresses). …

The graph indicates clearly that such flash worms can indeed be extraordinarily fast-infecting 95% of hosts in 510ms, and 99% in 1.2s. There is a long tail at the end due to the long tail in Internet latency data; some parts of the Internet are poorly connected and take a few seconds to reach. …

Can these results be extended to TCP services? If so, then our results are more grave; TCP offers worm writers a wealth of additional services to exploit. In this section we explore these issues. We conclude that top-speed propagation is viable for TCP worms, too, at the cost of an extra round-trip in latency to establish the connection and double the bandwidth if we want to quickly recover from loss. …

We believe a TCP worm could be written to be not much larger than Slammer. In addition to that 404 bytes, it needs a few more ioctl calls to set up a low level socket to send crafted SYN packets, and to set up a separate thread to listen for SYN-ACKs and send out copies of the worm. We estimate 600 bytes total. Such a worm could send out SYNs at line rate, confident that the SYN-ACKs would come back slower due to latency spread. The initial node can maintain a big enough buffer for the SYN-ACKs and the secondary nodes only send out a small number of SYNs. Both will likely be limited by the latency of the SYN-ACKs returning rather than the small amount of time required to deliver all the worms at their respective line rates.

To estimate the performance of such a small TCP flash worm, we repeated the Monte Carlo simulation we performed for the UDP worm with the latency increased by a factor of three for the hand- shake and the outbound delivery rates adjusted for 40 byte SYN packets. The results are shown in Figure 6. This simulation predicts 95% compromise after 1.3s, and 99% compromise after 3.3s. Thus TCP flash worms are a little slower than UDP ones because of the handshake latency, but can still be very fast. …

It appears that the optimum solution for the attacker – considering the plausible near-term worm defenses – is for a flash worm author to simply ignore the defenses and concentrate on making the worm as fast and reliable as possible, rather than slowing the worm to avoid detection. Any system behind a fully working defense can simply be considered as resistant, which the worm author counters by using the resiliency mechanisms outlined in the previous sections, combined with optimizing for minimum infection time.

Thus, for the defender, the current best hope is to keep the list of vulnerable addresses out of the hands of the attacker. …

The fastest worm seen in the wild so far was Slammer [10]. That was a random scanning worm, but saturated over 90% of vulnerable machines in under 10 minutes, and appears to have mainly been limited by bandwidth. The early exponential spread had an 8.5s time constant.

In this paper, we performed detailed analysis of how long a flash worm might take to spread on the contemporary Internet. These analyses use simulations based on actual data about Internet latencies and observed packet delivery rates by worms. Flash worms can complete their spread extremly quickly – with most infections occuring in much less than a second for single packet UDP worms and only a few seconds for small TCP worms. Anyone designing worm defenses needs to bear these time factors in mind.

An overview of Flash Worms

security, tech in changing society / /

From Stuart Staniford, Gary Grim, & Roelof Jonkman’s “Flash Worms: Thirty Seconds to Infect the Internet” (Silicon Defense: 16 August 2001):

In a recent very ingenious analysis, Nick Weaver at UC Berkeley proposed the possibility of a Warhol Worm that could spread across the Internet and infect all vulnerable servers in less than 15 minutes (much faster than the hours or days seen in Worm infections to date, such as Code Red).

In this note, we observe that there is a variant of the Warhol strategy that could plausibly be used and that could result in all vulnerable servers on the Internet being infected in less than thirty seconds (possibly significantly less). We refer to this as a Flash Worm, or flash infection. …

For the well funded three-letter agency with an OC12 connection to the Internet, we believe a scan of the entire Internet address space can be conducted in a little less than two hours (we estimate about 750,000 syn packets per second can be fit down the 622Mbps of an OC12, allowing for ATM/AAL framing of the 40 byte TCP segments. The return traffic will be smaller in size than the outbound. Faster links could scan even faster. …

Given that an attacker has the determination and foresight to assemble a list of all or most Internet connected addresses with the relevant service open, a worm can spread most efficiently by simply attacking addresses on that list. There are about 12 million web servers on the Internet (according to Netcraft), so the size of that particular address list would be 48MB, uncompressed. …

In conclusion, we argue that a small worm that begins with a list including all likely vulnerable addresses, and that has initial knowledge of some vulnerable sites with high-bandwidth links, can infect almost all vulnerable servers on the Internet in less than thirty seconds.

Library book returned 92 years late

From AP’s “Borrowed books returned to museum — 92 years later” (CNN: 6 November 2000):

The Field Museum of Natural History recently returned 10 volumes to the American Museum of Natural History in New York — 92 years late.

It seems a researcher from the New York museum took the books with him when he accepted a job at the Field Museum in 1908. American Museum officials suspect anthropologist Bertholt Laufer was using the books for research when he was hired away. …

Laufer had purchased 500 volumes — including texts on medicine and natural history — for the American Museum during an archaeological expedition to China from 1901 to 1904.

The American Museum didn’t even know 10 of the books — each belonging to a larger set — were missing until it decided in 1990 to computerize its collection.

Your job? Waiting in line for others.

business, law, politics, weird, writing ideas / /

From Brian Montopoli’s “The Queue Crew: Waiting in line for a living” (Legal Affairs: January/February 2004):

ON CAPITOL HILL, a placeholder is someone paid by the hour to wait in line. When legislative committees hold hearings, they reserve seats for Congressional staffers, for the press, and for the general public. The general-public seats are the only ones available to the so-called influence peddlers, the Washington lawyers and lobbyists whose livelihood depends on their ability to influence legislation. These seats are first come, first served, which is where the placeholders (also called “stand-ins” or “linestanders”) come in. Since most lobbyists and lawyers seeking to rub shoulders with lawmakers don’t have time to wait in line themselves, they pay others to do it for them.

Rather than use an independent contractor, most influence peddlers secure placeholders through one of the two companies that control about 80 percent of the market: Congressional Services Company and the CVK Group, both of which have rosters of on-call placeholders at the ready. Most of the time, placeholders are asked to wait for just a few hours, often arriving around 5 a.m. to wait for hearings scheduled for 10 a.m. If seats are in great demand, however, placeholders can be asked to get in line several days in advance. Congressional Services charges its clients $32 to $40 per hour for each placeholder, and the placeholders themselves make $10 to $15 an hour. …

For the sake of logistics and appearances, the lines usually form outdoors and stay there until a few hours before a hearing. …

Today, however, most placeholders are not nimble students out to earn a little spending money but older men and women trying to make ends meet. Jim Keegan is one of the “Van Gogh veterans,” a group of placeholders discovered by Congressional Services in 1998 when they were standing in line to get coveted free tickets to the Van Gogh exhibit at the National Gallery of Art. …

Now he said he has time to pursue his interests and get paid. “I’ll probably make $2,000 to $3,000 in a good month,” he said. “That’s more than I made at my old job.”

There is a collegial atmosphere among the placeholders – if you leave to go get something to eat, you aren’t going to lose your spot – but simple tasks like going to the bathroom present challenges. During the day, placeholders can go into the Rayburn Building, but after hours they have to make their way over to the public bathrooms at Union Station. Getting sleep is also a problem. Since the lines form on public sidewalks, placeholders are technically not allowed to sit down, and though the Capitol Hill police often ignore them, there are evenings when an overzealous officer will repeatedly wake them up and tell them to stand. …

Once, a group upset over banking regulations brought busloads of protesters to a hearing, only to discover that they wouldn’t be able to get in, thanks to the placeholders. A scuffle ensued, but the placeholders held their ground.

In general, however, most staffers and politicians don’t even notice the placeholders they pass on their way to work. …

Since hearings can be rescheduled or closed to the public at the last minute, the placeholding services insist on getting paid regardless of whether their clients succeed in getting in. Keegan and Herzog’s long wait, for example, ended before they could pass along their spots to their clients: The housing hearing was cancelled because of partisan infighting, and after two days and 20 hours of waiting, the placeholders were sent home on Tuesday at 6:30 p.m.

The next morning, however, after showers and a change of clothes, many of them were back, this time to wait for a healthcare hearing before the Commerce Committee. When I arrived at the Rayburn Building at 9 a.m., over 70 people were waiting to get into the hearing, and by 10, when it was scheduled to start, there were more than 200. The line began around the corner from the hearing room and snaked past elevator banks and Congressional offices. At the front were mostly placeholders, among them a bored-looking young man with red sneakers and a hat worn sideways and a woman in her late 30s wearing a frayed sweatshirt that read “OJ SIMPSON: JUICE ON THE LOOSE.” …

Thirty minutes before the hearing began, the clients started showing up. The placeholders were identified by placards or by assistant managers who worked the line. A bald white man in his 40s with a yellow tie and an expensive suit took his spot and thanked his placeholder. (Congressional rules prohibit tipping.)

The 80/20 rule

business, commonplace book / /

From F. John Reh’s “How the 80/20 rule can help you be more effective” (About.com):

In 1906, Italian economist Vilfredo Pareto created a mathematical formula to describe the unequal distribution of wealth in his country, observing that twenty percent of the people owned eighty percent of the wealth. In the late 1940s, Dr. Joseph M. Juran inaccurately attributed the 80/20 Rule to Pareto, calling it Pareto’s Principle. …

Quality Management pioneer, Dr. Joseph Juran, working in the US in the 1930s and 40s recognized a universal principle he called the “vital few and trivial many” and reduced it to writing. …

As a result, Dr. Juran’s observation of the “vital few and trivial many”, the principle that 20 percent of something always are responsible for 80 percent of the results, became known as Pareto’s Principle or the 80/20 Rule. …

The 80/20 Rule means that in anything a few (20 percent) are vital and many(80 percent) are trivial. In Pareto’s case it meant 20 percent of the people owned 80 percent of the wealth. In Juran’s initial work he identified 20 percent of the defects causing 80 percent of the problems. Project Managers know that 20 percent of the work (the first 10 percent and the last 10 percent) consume 80 percent of your time and resources. You can apply the 80/20 Rule to almost anything, from the science of management to the physical world.

You know 20 percent of you stock takes up 80 percent of your warehouse space and that 80 percent of your stock comes from 20 percent of your suppliers. Also 80 percent of your sales will come from 20 percent of your sales staff. 20 percent of your staff will cause 80 percent of your problems, but another 20 percent of your staff will provide 80 percent of your production. It works both ways.

The value of the Pareto Principle for a manager is that it reminds you to focus on the 20 percent that matters. Of the things you do during your day, only 20 percent really matter. Those 20 percent produce 80 percent of your results.

The difficulties in establishing time of death

law, science, technology / /

From Jessica Sachs’s “Expiration Date” (Legal Affairs: March/April 2004):

More than two centuries of earnest scientific research have tried to forge better clocks based on rigor, algor, and livor mortis – the progressive phenomena of postmortem muscle stiffening, body cooling, and blood pooling. But instead of honing time-of-death estimates, this research has revealed their vagaries. Two bodies that reached death within minutes of each other can, and frequently do, show marked differences in postmortem time markers. Even the method of testing eye potassium levels, which was recently hailed as the new benchmark for pinpointing time of death, has fallen into disrepute, following autopsies that showed occasional differences in levels in the left and right eye of the same cadaver. …

And the longer a body is dead, the harder it is to figure out when its owner died. In their book The Estimation of Time Since Death in the Early Postmortem Period, the world-renowned experts Claus Henssge and Bernard Knight warn pathologists to surrender any pretensions of doing science beyond the first 24 to 48 hours after death.

Windows Metafile vulnerability

security, technology / /

From Noam Eppel’s “Security Absurdity: The Complete, Unquestionable, And Total Failure of Information Security“:

On Dec. 27, 2005 a Windows Metafile (.WMF) flaw was discovered affecting fully patched versions of XP and Windows 2003 Web Server. Simply by viewing an image on a web site or in an email or sent via instant messenger, code can be injected and run on the target computer. The vulnerability was in the Windows Graphics Rendering Engine which handles WMF files, so all programs such as Internet Explorer, Outlook and Windows Picture and Fax viewer which process this type of file were affected.

Within hours, hundred of sites start to take advantage of the vulnerability to distribute malware. Four days later, the first Internet messenger worm exploiting the .wmf vulnerability was found. Six days later, Panda Software discovers WMFMaker, an easy-to-use tool which allows anyone to easily create a malicious WMF file which exploits the vulnerability.

While it took mere hours for cybercriminals to take advantage of the vulnerability, it took Microsoft nine days to release an out-of-cycle patch to fix the vulnerability. For nine entire days the general public was left with no valid defenses.

The WMF Flaw was a security nightmare and a cybercriminal dream.It was a vulnerability which (a) affected the large majority of Windows computers (b) was easy to exploit as the victim simply had to view an image contained on a web site or in an email, and (c) was a true zero-day with no patch available for nine days. During those nine days, the majority of the general population had no idea how vulnerable they were.
