Two-string kite flying

Yesterday I went to Hanlan’s Point beach with some friends, in part to fly my DC Sport dual control nylon kite: 60″ wide.

It’s a fun thing to fly. The only control surface you have is the entire airfoil, and the only axis of motion you can directly control is roll, by altering the relative length of the two strings.

The kite has a flight envelope comprised of a curved two-dimensional surface, with varying levels of power in different places. With very little practice, most people get a high degree of control. One guy walking along the beach was able to do it almost immediately when I suggested he give it a try.

It would be neat to get a parasail-style four-string kite with more power, pitch as well as roll control, and the option for controlled reversible landings.

Jacobs’ four top requirements for cities

To generate exuberant diversity in a city’s streets and districts, four conditions are indispensable:

  1. The district, and indeed as many of its internal parts as possible, must serve more than one primary function; preferably more than two. These must insure the presence of people who go outdoors on different schedules and are in the place for different purposes, but who are able to use many facilities in common.
  2. Most blocks must be short; that is, streets and opportunities to turn corners must be frequent.
  3. The district must mingle buildings that vary in age and condition, including a good proportion of old ones so that they vary in the economic yield they must produce. This mingling must be fairly close-grained.
  4. There must be a sufficiently dense concentration of people, for whatever purposes they may be there. This includes dense concentration in the case of people who are there because of residence.

The necessity of these four conditions is the most important point this book has to make.

Tour of Ottawa sights

My Saturday in Ottawa involved a rather comprehensive trek.

Beginning at the home of my friends Andrea and Mehrzad, I walked up Booth Street – past the first apartment I rented in town and the War Museum – and across the Chaudiere Bridge to the Terrasses de la Chaudière complex which includes Environment Canada headquarters.

On the Quebec side, I then walked to the Museum of Civilization, which has been rebranded by the Harper government as the Canadian Museum of History. I then crossed the Alexandra bridge back into Ontario, putting me near the National Gallery. I walked through Major’s Hill Park and crossed the Rideau Canal near the Chateau Laurier. I then entered Parliament Hill, walking the scenic northern edge, looking out over all the major government buildings of the National Capital Region.

I carried on west, walking around the Supreme Court, before heading east again to buy a ticket for the guided tour of Centre Block. While near Parliament Hill, I had a peek at the building where I used to work for the Privy Council Office, along with the Blackburn Building (home of the PCO library) and the Langevin Block (home of the Prime Minister’s Office).

I then walked through the downtown core, mostly along Bank Street, getting a peek at the new Venus Envy location before diverting west down Somerset. I also had a quick peek at the headquarters of the Department of Finance and Treasury Board Secretariat. I also talked to some not-especially-interested salespeople at Henry’s cameras about the relative merits of the 6D and 5D Mk III.

All through the walk, I was struck by how small a place Ottawa is. Having spent five years working there, every neighbourhood is peppered with memories and (at least on a pleasant summer’s day) they can all be walked to quite easily.

I walked down Somerset all the way back to the Booth neighbourhood and said hello to Andrea’s hilarious dogs before following the river back to Parliament Hill for my tour. The guided tour included the elegant corridors and atriums of Centre Block, committee rooms, the senate, and the extremely beautiful Library of Parliament.

After the tour, I walked up Elgin Street, passing the pub where I used to do trivia on a team of tax economists on Tuesday nights. I headed south to the Museum of Nature before having a look at the much-developed Beaver Barracks complex where I used to live. I then walked back to Bank Street and south through The Glebe to the redeveloped Landsdowne Park.

From there, I visited the Bank Street canal bridge and wandered along the canal and through neighbourhoods as far as Dow’s Lake, before making my way back to Andrea’s via the Natural Resources Canada complex on Booth Street.
