Powell’s Books in Portland (short observations)

Image result for Powell's books Portland

So I went to a bookstore in Portland as part of a short vacation trip with my Dad. It was Powell’s books which is truly a great bookstore. Three or four stories of anything you could want but Limbaughs’ latest book. The new age shamanistic ritual section was especially fun and expansive.

By far my favorite was the Northwest section, they really did have lots of hard to find books about the local history and architecture and the sheer uniqueness of Pacific Northwest. It was refreshing to find a selection of books that wouldn’t be readily available in any other part of the world. I hope a visitor to Chengdu Sichuan can visit a bookstore filled with odd books about Sichuanese stuff that she has never heard about before.... [Read More]

Half a Million Spammers

Pumpkin spice SPAMEarlier today, on the last day of 2019, Ratburger.org blocked the 500,000th attempt to pollute the site with spam comments or to register new user accounts in order to make spam postings.  As of this post, the total spam blocked has already climbed to 500,254.

The Castle Crumbles

Zoning law is kinda my thing. And in all the municipal ordinances and model ordinances I’ve worked with over the years, the jewel in the crown of the zoning structure has always been the Single Family Residential District. R-1. That meant you could only build a detached residence for one family, on a lot sized as large as the municipality could get away with designating without being in danger of having the ordinance invalidated as exclusionary. No heavy industry (horrors!) no intense commercial uses, although institutional uses like churches and schools were usually accommodated. So mote it be, ever since the US Supreme Court blessed the concept of zoning in 1926 in Village of Euclid v. Ambler.

The definition of “family” became a fraught issue during de-institutionalization of the mentally and physically and addictionally challenged, with their advocates wanting groups of them to reside in, well, residential, zones, and the neighboring homeowners wanting that not so much. Most ordinances I’ve encountered defined family as any number of people related by blood or marriage, but no more than five unrelated persons provided they lived together as a single housekeeping unit. This was generous; in Village of Belle Terre the US Supreme Court had indicated, at least in dicta, that the number of unrelated persons who could reside together in R-1 might be limited to only two. It used to be all about preserving splendid isolation, so long as the municipality somewhere provided for cheaper and denser types of residences. Americans, famously, wanted “elbow room”. Isn’t that why Dan’l Boone and his ilk pushed ever Westward?... [Read More]

Books of the Year: 2019

Gnome carrying pile of booksHere are my picks for the best books of 2019, fiction and nonfiction. These aren’t the best books published this year, but rather the best I’ve read in the last twelve months. The winner in both categories is barely distinguished from the pack, and the runners up are all worthy of reading. Runners up appear in alphabetical order by their author’s surname. Each title is linked to my review of the book.

Space Scoreboard: 2019

SpaceX Falcon Heavy liftoffThe year 2019 is almost over, and unless somebody slips one in at the last moment, we can sum up activity in orbital space launches over the last twelvemonth.  Here are orbital launches (some of which placed more than one satellite in orbit) by country of launch, in decreasing order by number of successful launches.  Specifying “country of launch” is simultaneously significant and somewhat sloppy: three Soyuz launches were conducted from the European spaceport in French Guiana, and are counted as European despite the rockets having been made in Russia and sold to Arianespace, which launched them.  Six Rocket Lab Electron launches performed from their Mahia site in New Zealand are listed under New Zealand despite Rocket Lab’s being (for regulatory, export control, and bowing to the empire purposes, nominally a U.S. company).  Russian launches from the Baikonur Cosmodrome in Kazakhstan are, however, listed as Russian, as the launchers are manufactured in Russia and launched by personnel working for Russian companies or military services.

  • China:  34 launches, 32, successes, 2 failures
  • Russia: 25 launches, 25 successes
  • United States: 21 launches, 21 successes
  • India: 6 launches, 6 successes
  • New Zealand: 6 launches, 6 successes
  • Europe: 6 launches, 5 successes, 1 failure
  • Japan: 2 launches, 2 successes
  • Iran: 2 launches, 2 failures.  In addition, another launch vehicle exploded on the pad during preparations for launch.
  • Total: 102 launches, 97 successes (95%), 5 failures (5%)

Of the 97 successful launches, 61 were to low Earth orbits, including polar and Sun-synchronous orbits, 9 were to medium Earth orbits (mostly used by navigation satellites), 24 were to geosynchronous orbits, 2 were to high Earth or lunar transfer orbits, and 1 was to a heliocentric orbit.  All 5 launch failures were attempts to launch into low Earth orbit.
