The busyness economy works on face time, incremental improvement, strategic long-term planning, return on investment, and hierarchical control. The burst economy, enabled by the Web, works on innovation, flat knowledge networks, and discontinuous productivity:
Harvard Business School professor Andrew McAfee identifies the culture clash between these two economies:
We’ve spent the past couple weeks in my MBA class discussing E2.0 technologies (including blogs, wikis, and prediction markets), approaches, and initiatives. One of the most interesting things for me about these classes has been how often students bring up one specific concern: that people who use the new tools heavily — who post frequently to an internal blog, edit the corporate wiki a lot, or trade heavily in the internal prediction market — will be perceived as not spending enough time on their ‘real’ jobs.

A couple years ago, someone (allegedly, they were never caught) set fire to a lumber mill in 100 Mile House, BC, Canada. Definitely was not a nice occurrence, but at least the heat from the fire created this wonderful keyboard sculpture, which I've photographed in tiny detail. Because someone will surely ask, the keyboard is from an older HP. Vectra, I think.

Shipping Containers, 2007
Depicts 75,000 shipping containers, the number of containers processed through American ports every day.
Running the numbers: An American Self-Portrait
This new series looks at contemporary American culture through the austere lens of statistics. Each image portrays a specific quantity of something: fifteen million sheets of office paper (five minutes of paper use); 106,000 aluminum cans (thirty seconds of can consumption) and so on. My hope is that images representing these quantities might have a different effect than the raw numbers alone, such as we find daily in articles and books. Statistics can feel abstract and anesthetizing, making it difficult to connect with and make meaning of 3.6 million SUV sales in one year, for example, or 2.3 million Americans in prison, or 426,000 cell phones retired every day. This project visually examines these vast and bizarre measures of our society, in large intricately detailed prints assembled from thousands of smaller photographs.

Last week's Panorama was on the ''danger" of wifi networks in schools. I missed the show but caught a preview of it on Radio 2 while I was out in the van. It bore no relation to the excellent BBC science reporting of my youth. I grew up on a steady diet of 'Tomorrow's World' and 'Horizon' but these days there is no 'Tomorrow's World' and 'Horizon' has been dumbed down beyond recognition. 'Panorama' used to be the Beeb's flagship current affairs strand but last week it indulged in bad science. I resisted the temptation to don my tinfoil hat and throw popcorn at the screen.
Let's get some perspective here people, the maximum legal output of a 2.4 wifi card in the UK is 100 mW. Your mobile phone can put out a legal maximum of 2W.

From The Fischbowl (a staff development blog for Arapahoe High School), Karl Fisch explains...
As I write this, I realize that I've created a trilogy of sorts. The "What If" presentation was a look at the past, at the resistance to change in education. The "Did You Know" presentation was mainly a look at our present, at the incredible changes that are happening due to "flat world" factors and technological change (with a dash of prediction thrown in). And now "2020 Vision" is a look "back" at our future from the year 2020. (Ummm, yeah, sure, I planned to create a trilogy. That's my story and I'm sticking to it.) Maybe by having one possible version of the future to consider we can get past the natural resistance to change. If nothing else, I hope it's another example of David Warlick's "telling the new story" to get those conversations started.

We have a dictatorship in Russia, we know it's been heading there for a while but banning an opposition party on the basis that there are too few members really seems to have tipped over yet another edge.
Earlier this week I caught an interview on Womans Hour on Radio 4 with the sister of the murdered Russian journalist, Anna Politkovskaya. Her last book has just been published posthumously, The Guardian has a few extracts, 'Fascism is in fashion' makes a really chilling read.

The NY Times has a pretty ominous story about vanishing bees:
This winter, in more than 20 states, beekeepers have noticed that their honeybees have mysteriously vanished, leaving behind no clues as to their whereabouts. There are no tell-tale dead bodies either inside colonies or out in front of hives, where bees typically deposit corpses of dead nestmates.
What’s more, the afflicted colonies tend to be full of honey, pollen and larvae, as if all of the workers in the nest precipitously decamped on some prearranged signal. Beekeepers are up in arms — last month, leaders in the business met with research scientists and government officials in Florida to figure out why the bees are disappearing and how to stop the losses. Nobody had any answers.
Back in the early 90s, I remember hearing mutterings about problems with the UK bee populations, I remember virus infections being suggested, but it kind of dropped from the edges of the news just as quickly as it came in. It looks like the *crisis* has been quietly going on for some 30 years over here. There is more on this on the Bumblebee Conservation Trust website as well as some really pretty bee pics in the gallery.

I found treasure at the local boot sale in the form of four copies of a magazine called 'Practical Television'. They were from the early 50's, 1950-1954. Sadly the cover was busted on the first one but the contents were intact.
The first edition was published in April 1950 and in the editorial at the front in concluded with:
"Although paper for periodicals became de-rationed as from March 1st, production problems still make it difficult to ensure supplies."
There is an article on page 21 entitled, Building the "Viewmaster": An Amateur Describes his Experiences in Building this Popular Home-constructor Set.
In most of us is the desire to create, to see something grow under our hands, and be able to say, possibly with ill-concealed yet justifiable pride, "I built that".
Those of us who grew up with the century were fortunate in being on the "ground floor". It was radio in the early stages. We quickly mastered the simple principles and construction of the crystal set, and quite naturally graduated to the one, two and multi-valve straight sets. But as radio became more of an exact science, and the building of successful receivers required technical ability and expensive calibrating instruments, many erstwhile enthusiasts found the going too difficult and reluctantly downed tools.
I was one of them.
As a spectator I watched the march of the industry, growing more than ever concious of my limitations with the event of television.
The old enthusiasm gripped me. I couldn't afford a television receiver; could I build one? One glance at the chassis almost frightened me and quickly dispelled the forlorn hope I entertained of becoming an early "viewer".
And so to Radiolympia 1949.
I must confess that when I saw the "Viewmaster" Envelope on the T.C.C. Stand, I imagined it to be directed to the more advanced amateur. Only by chance did I catch a glimpse of the full-sized wiring diagrams. Here was something I did understand. Moreover, the sound and vision reproduction on the demonstration receiver was of a very high standard..
A close and more leisurely examination later of the contents of the envelope so impressed me with the extreme simplicity of construction that I decided to build the "Viewmaster".
Some friends to whom I shared the charts and conveyed my intentions were sceptical. "It looks too simple, " they said. "There must be some snags somewhere."
These remarks gave me an idea. "Why not make notes as I build the receiver?" I thought. "There may be little points on which my experience will help others. If there are snags, I shal find them. If there are no snags, then many hesitant ones will be encouraged to commence building the 'Viewmaster' and ultimately enjoy the thrill of proudly saying, 'Yes, I built it.'"
And so he begins a series of articles on the building of the "Viewmaster". It's not actually a kit, it's a set of instructions comprising 8 full sized drawings and a 32 page booklet, sponsored by 8 British component manufacturers. Adverts for components "specified for the Viewmaster" litter the magazine.
"Telenews" the news section at the back of the magazine, estimate that at the time of writing:
There are approximately 285,500 television receivers in use at the present time and as the B.B.C. estimates that at least four people look at each receiver the total number of viewers is reasonably accurately estimated to be 1,142,000.
We are assured that production was catching up with demand.
In this context, things like the Homebrew Computer Club in 1970s in Silicon Valley fit right into this kind of technological continuum (though they probably had better teeth in the HCC...)
I have a couple of scans from the magazines on my flickr pages for your enjoyment, they really are quite... something. More when I get the chance.
Why pay $20,000 for a commercial link to run your television station when a $10 kitchen wok from the Warehouse is just as effective?
This is exactly how North Otago's newest television station 45 South is transmitting its signal from its studio to the top of Cape Wanbrow, in a bid to keep costs down.
45 South volunteer Ken Jones designed the wok transmitter in his spare time last year when he wanted to provide wireless broadband to his Ardgowan home.
"A group of us wanted to connect our computers to each other and then we worked out a way to get of getting the signal between two points," he said.
He discovered satellite dishes were between $100 to $400 retail and that smaller dishes, the same size as a wok, were $80.
Mr Jones thought he could do better.
Along with friend Murray Bobbette they worked out mathematical equations to prove the curved metal face of a wok would have the same effect as a small satellite dish.
"We have spent a lot of time getting it right -- the first time we installed one we had it up a pole with the handle still on the end of the wok," he said.
"We had it connected to the woolshed and initially you couldn't get a signal the width of the paddock and now it can reach up to 20km."
When the television station 45 South (UHF channel 41) started up in September last year, Mr Jones thought the same technique could be applied.
"The $20,000 for a commercial link was just money we didn't have, so we bought several woks from The Warehouse instead which was convenient and cheap," he said.
Pre-recorded clips at the studio are fed through a computer and beamed to Cape Wanbrow where they are relayed off to television sets around North Otago.
The classic case of Kiwi ingenuity has made its way onto the internet and the technique has been posted by an American website, Mr Jones said.
"People wanted to know all the details about how to make their own, so it is now all publicly documented," he said.
One of the issues they had to deal with was making the pole that the wok sits on high enough to clear the Kingsgate Brydone Hotel.
They needed a clear path from the station to the hill, so the only way was up, building the pole more than eight metres high.
Mr Jones said one wok was providing Oamaru with the signal at present and there was no need to provide another wok for some time
