Tall Ships Victoria 2008

Between June 26th and 29th Victoria will host about 30 Tallships, which if you haven’t seen before is a truly awesome spectacle. From Tallshipsvictoria.ca

“Visitors will be able to walk the decks, touch the massive timbers, look up through the rigging at the sky, and turn back the clock to a time when our city’s future was being built by ships like these. In addition, we are planning an ambitious program of interactive educational activities, concerts, craft fairs and festive events that will celebrate our history and BC’s 150th anniversary.”

Soren Larsen

Having worked on a tallship, the idea of ‘looking up through the rigging’ doesn’t seem *that* appealing, but maybe I can weasel my way onto a day sail. Any chance to hike up to the t’gallant again! They should seriously having a day of racing, or at least plan a sail-past – Something so that people can experience ships as they were meant to be seen – on the water with full sails and landlubbers puking their guts out.

Highly Efficient Datacenters for Grid Computing

Grid services and platforms that are always on and always available are awesome for running cheap, highly-available services on the internet. That’s great, because it means the barrier to entry, and the cost to deliver those services is low making innovations by small teams with little to no cash much more possible. What it means though, is that we’re creating Datacenters with tons of capacity that’s being used during two peak periods throughout the day. After speaking with a few Datacenter architects are the Sun Open House, I realized that not only are todays DC designs supremely inefficient, but most of the stuff running in them isn’t being used up to 80% of the day. Cooling costs are extremely high, and the cost of running a grid to sustain maximum capacity + wiggle room is shocking. So in order to reduce those costs some companies like HP and Sun are actively looking at computers that will turn themselves off or into ‘low power’ mode when not being used. That’s cool, but I don’t think we have to wait for them to build that system. If a computer isn’t required, then a remote ‘green monitor’ can log in and gracefully shutdown unnecessary systems, and the magic known as ‘Wake-on-LAN‘ can be used to bring them back up again. If you could build that into your grid then you could instantly save energy, not only to run a system, but on cooling as well. Of course, this would have to be mapped to a prediction engine that would say ‘traditionally we’ve needed more capacity at 7:30AM Pacific, so boot up some systems’, but that would be a really fun project.

Let’s take it one step further.

If energy costs are really high then you want to use as  little of it as possible. So how about grabbing compute cycles from a grid that’s in the peak power zone for Solar? It’s cheap to send a few hundred gigs of data to be crunched, but its expensive to work on it. If you could do that, then you could have your capacity for computing literally follow the Sun. Someone has to work out the math on what’s cheaper – moving electricity, or moving the cycles, but my bets on the cycles because I think a mile of fiber costs less than a mile of High-voltage lines.

DC A wants to send a data crunching job offsite. It’s going to check the International Grid Exchange (I just made this up) for cheap capacity somewhere. DC B’s rate is 5.28$/teraflop hour because it’s in Iceland (which has cheap bandwidth and geothermal energy – oh and its cold). DC A’s rate for the same service is $8.22/teraflop hour, so DC A exports that task to DC B, and when it’s done DC A gets the resulting data set – or a trickle of data comes back over the tasks compute time.

Now we have a market where the most efficient winner gets the utilization. True utility computing, true scaling on demand, no market hype or hand waving.

You could even buy Grid ‘Futures’; You want to make sure you get the capacity, or you could prospect and buy chunks of time for resale later on. Basically turning computing into a true commodity.

I hope that’s one way to make computing a lot more efficient.

Sustainability and the Food Crisis

The largest contributing factor to the price of food is the cost of fossil fuels. Not only are fossil fuels used to transport food, they’re used in pesticides, inorganic fertilizers, and in the machinery used to grow the food. They’re used for just-in-time delivery of perishable food items, in food additives and in the production of the containers we use to package, ship and deliver food. The 3000 mile salad is the best example of this. Transportation costs alone for salad being delivered across the country mean that 127 calories of energy (fuel) is spent on 1 calorie of energy derived from food. That’s pretty appalling, but it also states the obvious: That the price of food is correlated to the price of oil.

Unfortunately this has been obvious for quite some time to a majority of individuals who watch oil prices. Talk of peak oil makes peoples conspiracy theorist radar go ‘blip’, even though in any closed system with a finite set of resources you’re bound to run into a point where demand outstrips supply. At that point, the scarcity of your resource means higher prices, and higher prices means that people with low incomes have to either spend more money on those resources, or forego them altogether. That’s a problem for the 800 million people in the world who have their food delievered to them via famine relief. Not only is the cost of food production getting higher, but the cost of delivering that food half way across the planet being exacerbated, and it’s not Ok.

Groups responsible for famine releif are already asking for additional funding to help deal with the problem, but unless we can figure out a way to cheaply supply the impoverished with food, Christmas won’t be the only time you see starving children on Television. We have to find new ways to store and deliver energy, build highly efficient transportation systems, and consume less of those products.

Here’s a list of interrelated problems:

Oil is the primary ingredient in growing food – Its not sustainable and it destroys the soil

GM Foods are being heralded as answers – they’re not : Monocultures are bad

Transportation systems are grossly inefficient – We need a fast cheap rail system

We eat too much meat – Cows are fed using grain, but it costs more to grow a cow then you get out of eating a cow.

We drive too much – Ban the Hummer, embrace Electric, or better yet – ride a bike

The Suburbs Suck – Denser, walkable living arrangements are better for community and the environment.

Who’s smart enough to figure those out?

Shutdown Day

I’ve been glued to my computer for about 18 years now. It’s become such an integral part of my day to day life that I actually know every single time that I haven’t used one. 3 times when I went away to camp, and for a couple weeks while I was sailing (It would have been longer but I brought my laptop traveling). One thing that I try to do is have computer-free Sundays but I usually fail miserably. This May 3rd, I’m going to try really hard not to use my computer (or even a cell phone).

Go to http://shutdownday.org/ and let them know whether or not you can turn off the computer, just for one day.
