Cameraphones are different cameras & different phones

From David Pescovitz’s “The Big Picture“:

Mobile researcher John Poisson, CEO of the Fours Initiative, focuses on how cameraphones could revolutionize photography and communication — if people would only start using them more.

As the leader of Sony Corporation’s mobile media research and design groups in Tokyo, John Poisson spent two years focused on how people use cameraphones, and why they don’t use them more often.

TheFeature: What have you learned over the course of your research?

Poisson: People think of the cameraphone as a more convenient tool for digital photography, an extension of the digital camera. That’s missing the mark. The mobile phone is a communications device. The minute you attach a camera to that, and give people the ability to share the content that they’re creating in real time, the dynamic changes significantly.

TheFeature: Aren’t providers already developing applications to take advantage of that shift?

Poisson: Well, we have things like the ability to moblog, to publish pictures to a blog, which is not necessarily the most relevant model to consumers. Those tools are developed by people who understand blogging and apply it in their daily lives. But it ignores the trend that we and Mimi Ito and others are seeing as part of the evolution of photography. If you look at the way people have (historically) used cameras, it started off with portraiture and photographs of record — formalized photographs with a capital “P.” Then as the technology evolved, we had this notion of something called a snapshot, which is much more informal. People could take a higher number of pictures with not so much concern over composition. It was more about capturing an experience than photographing something. The limit of that path was the Polaroid. It was about taking the picture and sharing it instantly. What we have today is the ability to create today is a kind of distributed digital manifestation of that process.

30 seconds to impress

From The Scotsman‘s “Men, you have 30 seconds to impress women“:

HALF of all women make their minds up within 30 seconds of meeting a man about whether he is potential boyfriend material, according to a study on speed-dating.

The women were on average far quicker at making a decision than the men during some 500 speed dates at an event organised as part of Edinburgh Science Festival.

The scientists behind the research said this showed just how important chat-up lines were in dating. They found that those who were “highly skilled in seduction” used chat-up lines that encouraged their dates to talk about themselves in “an unusual, quirky way”.

The top-rated male’s best line was “If you were on Stars In Their Eyes, who would you be?”, while the top-rated female asked bizarrely: “What’s your favourite pizza topping?”

Failed Casanovas were those who offered up hackneyed comments like “Do you come here often?”, or clumsy attempts to impress, such as “I have a PhD in computing”.

About a third of the speed dates were actually over within the first 30 seconds, but there was a marked difference between the sexes with 45 per cent of women coming to a decision within 30 seconds, compared with only 22 per cent of men.

… Conversation topics were also assessed. Only 9 per cent of pairs who talked about films agreed to meet again, compared with 18 per cent who spoke about the subject found to be the most suitable for dating: travel.

It is thought women’s taste for musicals clashed with the male liking for action films, while talking about “great holidays and dream destinations” made people feel good and appear more attractive to each other.

Familiar strangers

From danah boyd’s “G/localization: When Global Information and Local Interaction Collide“:

In the early 1970s, Stanley Milgram was intrigued by what he called “familiar strangers” – people who recognized each other in public life but never interacted. Through experiments, he found that people are most likely to interact with people when removed from the situation in which they are familiarly strangers. In other words, two people who take the same bus every day for years may never interact, but if they were to run into each other in a different environment across town, they would say hello and talk about the bus. If they run into each other in a foreign country, they will immediately be close friends.

Culture, values, & designing technology systems

From danah boyd’s “G/localization: When Global Information and Local Interaction Collide“:

Culture is the set of values, norms and artifacts that influence people’s lives and worldview. Culture is embedded in material objects and in conceptual frameworks about how the world works. …

People are a part of multiple cultures – the most obvious of which are constructed by religion and nationality, but there are all sorts of cultures that form from identities and communities of practice. … Identification and participation in that culture means sharing a certain set of cultural values and ideas about how the world should work. …

Cultural norms evolve over time, influenced by people, their practices, and their environment. Culture is written into law and laws influence the evolution of culture. Cultures develop their own symbols as a way of conveying information. Often, these symbols make sense to those within a culture but are not parsable to those outside. Part of becoming indoctrinated into a culture is learning the symbols of that culture. …

… there are numerous cultural forces affecting your life at all times. How you see the world and how you design or build technology is greatly influenced by the various cultural concepts you hold onto. …

… algorithms are simply the computer manifestation of a coder’s cultural norms.

Google on the Google File System (& Linux)

From Sanjay Ghemawat, Howard Gobioff, & Shun-Tak Leung’s “The Google File System“:

We have designed and implemented the Google File Sys- tem, a scalable distributed file system for large distributed data-intensive applications. It provides fault tolerance while running on inexpensive commodity hardware, and it delivers high aggregate performance to a large number of clients. …

The file system has successfully met our storage needs. It is widely deployed within Google as the storage platform for the generation and processing of data used by our ser- vice as well as research and development efforts that require large data sets. The largest cluster to date provides hun- dreds of terabytes of storage across thousands of disks on over a thousand machines, and it is concurrently accessed by hundreds of clients. …

We have seen problems caused by application bugs, operating system bugs, human errors, and the failures of disks, memory, connectors, networking, and power sup- plies. Therefore, constant monitoring, error detection, fault tolerance, and automatic recovery must be integral to the system.

Second, files are huge by traditional standards. Multi-GB files are common. Each file typically contains many applica- tion objects such as web documents. When we are regularly working with fast growing data sets of many TBs comprising billions of objects, it is unwieldy to manage billions of ap- proximately KB-sized files even when the file system could support it. As a result, design assumptions and parameters such as I/O operation and blocksizes have to be revisited.

Third, most files are mutated by appending new data rather than overwriting existing data. Random writes within a file are practically non-existent. Once written, the files are only read, and often only sequentially. …

Multiple GFS clusters are currently deployed for different purposes. The largest ones have over 1000 storage nodes, over 300 TB of diskstorage, and are heavily accessed by hundreds of clients on distinct machines on a continuous basis. …

Despite occasional problems, the availability of Linux code has helped us time and again to explore and understand system behavior. When appropriate, we improve the kernel and share the changes with the open source community.

Bruce Schneier on what we should do

From Bruce Schneier’s “Searching Bags in Subways“:

Final note: I often get comments along the lines of “Stop criticizing stuff; tell us what we should do.” My answer is always the same. Counterterrorism is most effective when it doesn’t make arbitrary assumptions about the terrorists’ plans. Stop searching bags on the subways, and spend the money on 1) intelligence and investigation — stopping the terrorists regardless of what their plans are, and 2) emergency response — lessening the impact of a terrorist attack, regardless of what the plans are. Countermeasures that defend against particular targets, or assume particular tactics, or cause the terrorists to make insignificant modifications in their plans, or that surveil the entire population looking for the few terrorists, are largely not worth it.

Some thoughts on strong & weak social ties

From Ross Mayfield’s “The Weakening of Strong Ties“:

Mark Granovetter’s seminal paper, The Strength of Weak Ties (summary), revealed the difference between friends and acquaintances and how useful acquaintances can be for certain tasks like finding a job. The difference between a strong tie and weak tie can generally be revealed by time commitment underpinning the relationship. Strong ties are better for action, weak ties for new information.

But time has changed with new tools and social networking models at our disposal. For the first time many social networks are being made explicit, often without the knowledge of participants, at an accelerating pace and dramatically lowered search costs. This newfound transparency may very well make strong ties weaker. …

Top-down models, or weak tie systems, are particularly good at the breadth of sample and search. …

That said, weak tie systems provide real insight we didn’t have before. They have vast potential for revealing structural holes and other methods of enhancing social capital. So long as participation is voluntary, information flows monitored is public and constraints keep in check how people act upon intelligence these systems will become a critical competitive advantage for any company.

By contrast, bottom-up systems are built for people instead of companies. Within Friendster, Ryze, Tribe.net and LinkedIn connections are made through individual decisions upon of invitations, requests and confirmations. The network grows organically, decision by voluntary decision.

Identity production & sharing during adolescence

From danah boyd’s “Friendster lost steam. Is MySpace just a fad?“:

No, it is not just a moral panic that could make MySpace a fad. The primary value right now has to do with identity production and sharing, practices that are more critical to certain populations at certain times in their lives and it is possible that “growing up” will be marked by leaving MySpace (both for the teens and the 20-somethings).

Social capital: subcultural vs cultural

From danah boyd’s “Friendster lost steam. Is MySpace just a fad?“:

What’s at stake here is what is called “subcultural capital” by academics. It is the kind of capital that anyone can get, if you are cool enough to know that it exists and cool enough to participate. It is a counterpart to “cultural capital” which is more like hegemonic capital. That was probably a bit too obscure. Let me give an example. Opera attendance is a form of cultural capital – you are seen as having money and class and even if you think that elongated singing in foreign languages is boring, you attend because that’s what cultured people do. You need the expensive clothes, the language, the body postures, the social connects and the manners to belong. Limitations are economic and social. Rave attendance is the opposite. Anyone can get in, in theory… There are certainly hodgepodged clothes, street language and dance moves, but most folks can blend in with just a little effort. Yet, the major limitation is knowing that the rave exists. “Being in the know” is more powerful than money. You can’t buy your way into knowledge of a rave.

“Coolness” is about structural barriers, about the lack of universal accessibility or parsability. Structural hurdles mean people put in more effort to participate. It’s kinda like the adventure of tracking down the right parking lot to get the bus to go to the rave. The effort matters. Sure, it weeds some people out, but it makes those who participate feel all the more validated. Finding the easter egg, the cool little feature that no one knows about is exciting. Learning all of the nooks and crannies in a complex system is exhilarating. Figuring out how to hack things, having the “inside knowledge” is fabu.

Often, people don’t need simplicity – they want to feel proud of themselves for figuring something out; they want to feel the joy of exploration. This is the difference between tasks that people are required to do and social life. Social life isn’t about the easy way to do something – it’s about making meaning out of practice, about finding your own way.

What is a socio-technical system?

From “Why a Socio-Technical System?“:

You have divined by now that a socio-technical system is a mixture of people and technology. It is, in fact, a much more complex mixture. Below, we outline many of the items that may be found in an STS. In the notes, we will make the case that many of the individual items of a socio-technical system are difficult to distinguish from each other because of their close inter-relationships.

Socio-technical systems include:

Hardware Mainframes, workstations, peripheral, connecting networks. This is the classic meaning of technology. It is hard to imagine a socio-technical system without some hardware component (though we welcome suggestions). In our above examples, the hardware is the microcomputers and their connecting wires, hubs, routers, etc.

Software Operating systems, utilities, application programs, specialized code. It is getting increasingly hard to tell the difference between software and hardware, but we expect that software is likely to be an integral part of any socio-technical system. Software (and by implication, hardware too) often incorporates social rules and organizational procedures as part of its design (e.g. optimize these parameters, ask for these data, store the data in these formats, etc.). Thus, software can serve as a stand-in for some of the factors listed below, and the incorporation of social rules into the technology can make these rules harder to see and harder to change. In the examples above, much of the software is likely to change from the emergency room to the elementary school. The software that does not change (e.g. the operating system) may have been designed more with one socio-technical system in mind (e.g. Unix was designed with an academic socio-technical system in mind). The re-use of this software in a different socio-technical system may cause problems of mismatch.

Physical surroundings. Buildings also influence and embody social rules, and their design can effect the ways that a technology is used. The manager’s office that is protected by a secretary’s office is one example; the large office suite with no walls is another. The physical environment of the military supplier and the elementary school are likely to be quite different, and some security issues may be handled by this physical environment rather than by the technology. Moving a technology that assumes one physical environment into a different environment one may cause mismatch problems.

People Individuals, groups, roles (support, training, management, line personnel, engineer, etc.), agencies. Note that we list here not just people (e.g. Mr. Jones) but roles (Mr. Jones, head of quality assurance), groups (Management staff in Quality Assurance) and agencies (The Department of Defense). In addition to his role as head of quality assurance, Mr. Jones may also have other roles (e.g. a teacher, a professional electrical engineer, etc.). The person in charge of the microcomputers in our example above may have very different roles in the different socio-technical systems, and these different roles will bring with them different responsibilities and ethical issues. Software and hardware designed assuming the kind of support one would find in a university environment may not match well with an elementary school or emergency room environment.

Procedures both official and actual, management models, reporting relationships, documentation requirements, data flow, rules & norms. Procedures describe the way things are done in an organization (or at least the official line regarding how they ought to be done). Both the official rules and their actual implementation are important in understanding a socio-technical system. In addition, there are norms about how things are done that allow organizations to work. These norms may not be specified (indeed, it might be counter-productive to specify them). But those who understand them know how to, for instance, make complaints, get a questionable part passed, and find answers to technical questions. Procedures are prime candidates to be encoded in software design.

Laws and regulations. These also are procedures like those above, but they carry special societal sanctions if the violators are caught. They might be laws regarding the protection of privacy, or regulations about the testing of chips in military use. These societal laws and regulations might be in conflict with internal procedures and rules. For instance, some companies have implicit expectations that employees will share (and probably copy) commercial software. Obviously these illegal expectations cannot be made explicit, but they can be made known.

Data and data structures. What data are collected, how they are archived, to whom they are made available, and the formats in which they are stored are all decisions that go into the design of a socio-technical system. Data archiving in an emergency room it will be quite different from that in an insurance company, and will be subject to different ethical issues too.

More distribution channels = more viewers

From “NBC: iPod Boosts Prime Time“:

NBC’s “The Office” delivered a 5.1-its highest ratings ever-last Thursday among adults 18 to 49, a bump the network credits in large part to the show’s popularity as an iPod download. …

Such a connection between podcast success and broadcast ratings success is particularly significant because the NBC data is among the first available evidence of what network executives have been gambling on when striking their new media deals-that the new video platforms are additive because they provide more entry points into a show for consumers. …

NBC is confident that the iPod exposure contributed to the rise. …

The iTunes offering is bringing new audiences to the show that would not otherwise have watched, said Frederick Huntsberry, president of NBCU Television Distribution. “Consumers have choices, and we are not reaching all consumers with one technology,” he said.

ITunes is one way to bring fresh eyeballs to the network, he said, in particular the younger demo that uses video iPods. …

Yet ABC has also seen a ratings increase for its iTunes shows. To date since their debut on iTunes in October, both “Lost” and “Desperate Housewives” are up versus the same period last year. …

That growth and the knowledge that iTunes distribution possibly grew and certainly did not cannibalize ratings gave the ABC Disney Television Group the confidence to add another round of iTunes programs last week …

Create web sites with PONUR

From “Dive Into Mark“:

Web Content Accessibility Guidelines 2.0 working draft from April 24, 2002. Only 3 weeks old!

The overall goal is to create Web content that is Perceivable, Operable, Navigable, and Understandable by the broadest possible range of users and compatible with their wide range of assistive technologies, now and in the future.

  1. Perceivable. Ensure that all content can be presented in form(s) that can be perceived by any user – except those aspects of the content that cannot be expressed in words.
  2. Operable. Ensure that the interface elements in the content are operable by any user.
  3. Orientation/Navigation. Facilitate content orientation and navigation
  4. Comprehendible. Make it as easy as possible to understand the content and controls.
  5. Technology Robust. Use Web technologies that maximize the ability of the content to work with current and future accessibility technologies and user agents.

I like that: perceivable, operable, navigable, understandable, and robust. That deserves to become a new acronym, PONUR

Blogs as patio space

From Jim Hanas’ “The Story Doesn’t Care: An Interview with Sean Stewart“:

I grew up in Edmonton, Alberta, during the winter. There are two very essential conditions in Edmonton. There’s inside and outside, and there’s no real doubt about which is which. There’s a sharp line preserved between the two.

I now live in California. California is an interesting place to me—and reminds me a bit of the South, where I spent my summers—because in California, what with the weather being clement and the price of real estate being high, you spend a lot of time in this hybrid space. We could call it patio space or—if you’re in the South—front porch space. It’s clearly inside in some ways, but it’s public in other ways.

The world of the blog clearly exists in patio space, in porch space, in that “I’m going to invite you into a level of intimacy not usually accorded to strangers, and yet you’re still a stranger. I’m going to write a blog, and you and I will communicate with one another, sometimes with startling candor, and yet in this mixed, hybrid place.”

New communication, new art forms

From Jim Hanas’ “The Story Doesn’t Care: An Interview with Sean Stewart“:

I think that every means of communication carries within itself the potential for a form of art. Once the printing press was built, novels were going to happen. It took the novel a little while to figure out exactly what it was going to be, but once the press was there, something was going to occur. Once motion picture cameras were around, the movies—in some format or another—were going to happen.

I modestly or immodestly think that [developers of alternate reality games] got some things fundamentally right about the way the web and the internet want to tell stories in a way that not everyone had gotten quite when we lucked into it. What people do on the web is they look for things and they gossip. We found a way of storytelling that has a lot to do with looking for things and gossiping about them. …

Suspension of disbelief is a much more fragile creation in the kinds of campaigns we’re doing right now than it is in novels, where everyone has taken the last two hundred years to agree on a set of rules about how you understand what’s happening in a book. That hasn’t happened here. Right now, this is at an unbelievably fluid and dynamic stage—a whole bunch of things that have been figured out in other art forms, we’re working them out on the fly.

Paypal’s numbers

From “PayPal Prepares For a Challenge From Google“:

Long the Internet’s leading online-payments service, PayPal has a 24% market share of U.S. online payments, according to financial-institution consulting firm Celent LLC. PayPal, founded in 1998, boasts 96 million accounts with consumers who want to send payments online without revealing their credit-card or banking information to vendors. To use the service, customers simply set up an account with their credit-card or bank-account details, fill out a payment amount and the email address of the recipient, and send the payment via the Internet to PayPal. If the recipient doesn’t have an account, he simply opens one in order to collect the payment. The service gained traction on eBay and proved to be more popular than an in-house payment system it had been using.

For eBay, which acquired the online-payment business in October 2002, PayPal has been a big asset. The unit has helped accelerate trading on eBay’s auction sites in the U.S., Germany and the United Kingdom. Most recently, PayPal generated 23% of eBay’s total $1.3 billion quarterly revenue. And PayPal’s revenue is growing steadily: It was up 48% to $304.4 million in the fourth quarter compared with a year earlier.

The new American community: affinity vs. proximity

From “Study: Want Community? Go Online” [emphasis added]:

Nearly 40 percent of Americans say they participate in online communities, with sites around hobbies, shared personal interests, and health-related issues among the most popular. That’s according to a survey conducted by ACNielsen and commissioned by eBay.

The survey was conducted in late September. Of 1,007 respondents, 87 percent say they are part of a community. Of those, 66 percent say they participate in shared personal interest sites. Next comes hobby sites (62 percent), health community sites (55 percent), public issues sites (49 percents), and commerce sites (47 percent). Others participate in social or business networking sites (42 percent), sports sites (42 percent), alumni sites (39 percent), or dating sites (23 percent).

“We are finding that affinity is quickly replacing proximity as the key driver in forming communities,” said Bruce Paul, vice president of ACNielsen. …

“I think that a lot of people initially connect [on online communities] because they share information, which for a site like eBay is beneficial because they learn and grow from each other,” said Rachel Makool, director of community relations for eBay. “Then, of course, relationships form, and they grow from there.”

Researchers note that among offline communities, only membership in religious congregations (59 percent), social groups (54 percent), and neighborhood groups (52 percent) are more common than participation in online communities (39 percent). Professional groups (37 percent), activity groups (32 percent), school volunteer groups (30 percent), and health/country clubs (31 percent) came in behind online communities.

The study also shows that though 30 percent of online community members interact on a daily basis, only 7 percent of offline community members interacted that often. It also reveals that 47 percent of offline communities have an online component, such as e-mailing or chatting online.

Through the central blog dashboard at the intranet W3, IBMers now can find more than 3,600 blogs written by their co-workers. As of June 13 there were 3,612 internal blogs with 30,429 posts. Internal blogging is still at a stage of testing and trying at IBM but the number of blogs is growing rapidly …

US, Canada and Australia are very active countries but also in small European countries there are quite many internal bloggers. 147 in Sweden and 170 in the Netherlands to mention two examples. …

… the most common topics.

News or events that affect the business
“When IBM sold the personal computing division rumours were flying around before it actually happened and people were blogging about that, giving their opinions about what was going to happen and how it would affect IBM.”

Metablogging
“It’s a new technology of special interest to people who blog.”

Administrative things
“The little changes going on in the company — the water-cooler talk.”

Product announcements
“Not necessarily of general interest but of interest to the specific community working with the product.”
