Noctiwhat?
You may recall that back in Blog-2006-06-24, I wrote about ghostly blue clouds that I observed in the northern sky at the end of my observing session. Well, as it turns out, I was fortunate enough to catch a glimpse of a type of cloud known as a Noctilucent_cloud. These extremely high altitude clouds are typically too faint to be seen. However, when illuminated from below by a deeply set sun, they are visible as the beautiful blue colour I observed.
So, how did I figure this out? Well, I happen to read the Astronomy Picture of the Day, and Today’s Feature Image just happened to be of noctilucent clouds.
Review: Twenty Thousand Leagues Under The Sea
Review of Twenty Thousand Leagues Under The Sea by Jules Verne (9780553212525)★★★(https://b-ark.ca/2YK_eI)Twenty Thousand Leagues Under the Seas: A World Tour Underwater is a classic science fiction adventure novel by French writer Jules Verne; it was first published in 1870. The novel was originally serialized from March 1869 through June 1870 in Pierre-Jules Hetzel's periodical, the Magasin d'éducation et de récréation.
Well, last night I finally finished reading 20000 Leagues Under The Sea by Jules Verne (author of The Journey to the Center of the Earth and Around the World in 80 Days, among many others). This book, depicted in the 1954 Disney film of the same name, details the adventures of Professor Pierre Arronax, an oceanographer, and his companions Ned Land, a Canadian whaler and Conseil, the professor’s manservant, as they travel aboard the Nautilus, an advanced submarine designed and built by the infamous Captain Nemo.
In terms of historical context, Jules Verne is considered, along with a number of his contemporaries, as early examples of science fiction authors. Often compared with H.G. Wells (The Time Machine, The War of the Worlds), who used science fiction as a medium for making points about society, Verne focused on providing depictions of realistic technology that was logically extrapolated from that of the present day, and used that technology as a basis for more adventure-oriented works.
20000 Leagues most certainly fits this mold. The Nautilus and it’s attendant technology are carefully detailed by Verne, who attempts to very clearly describe the workings of the ship and it’s scientific underpinnings. This ship then becomes the vehicle (if you’ll pardon the pun) for an adventure story which carries the crew to nearly all points of the compass, from the Pacific to the Atlantic, Antartica to the North Sea, and into the deepest parts of the ocean. Along the way, the reader is introduced to countless species, running the gamut from coral to fish to whales, as well as various birds and semi-aquatic mammals.
Continue reading...Frickin' Deck...
It never ends. First it’s the damn beam being off. Then it’s all these building code issues. Now, after discussions with Chris, who was told by a Rona employeee that the builder almost certainly didn’t bolt his ledger to the house, and instead only nailed it, I’ve quickly realized that my own ledger board is only nailed to the house! ARGH!
So now what? You guessed it… I have to remove the deck boards closest to the house, drill holes and install lag screws or bolts, all of which is going to be that much more difficult because the damn joists and decking are in place. And who knows if they installed flashing (or something equivalent to stave off water). I sure hope they did, ‘cuz it’s too late now…
Update:
Well, I’ve confirmed that there is top flashing on the ledger board, there’s just no back flashing. Hopefully that’s sufficient in these parts.
Incidentally, it looks like this is a job I can safely do now. From what I can tell, the goal is to drill holes through the ledger board and into the house band board (the outside-most board that makes up the flooring). Then, drive through carriage bolts and secure with washers and nuts.
Actually, scratch that, I’m just going to use Lag Screws… less work than bolts, and sufficiently strong for my purposes.
Fun With Building Codes
So, when we went ahead with building our deck, I chose to rely on Roy to make sure it matched the building codes of Alberta. Looking back, this was probably not the greatest idea, since, if I was at least semi-knowledgeable in these things, I could ask questions and verify things as we went along.
Well, my buddy Chris has begun working on his deck, and he decided to actually read up on a few things, and now I’m starting to wonder about a few things myself. The biggest concern I have is that our lower tier is set up on 2x6 joists with an 8’ span between the two beams, and has a total depth of 12’, which means a 24” cantilever on either end, give or take. The problem is that, according to the building code, with 2x6 joists you can only have a 16” cantilever (actually, 15”, or 2.5 times the width of the joists). Whoops. Additionally, according to a safety officer Chris talked to, as of July 2005, they’re telling people to use 3 ply beams. We used 2 ply. Hopefully it’s just a suggestion…
Consequently, I think we’re just not going to apply for a permit any time soon. :) You don’t need one until you sell your house, which we don’t plan to do for quite a while (if ever… getting our armoire out of our bedroom is, I suspect, nigh on impossible), and even then, the buyer can choose to purchase anyway and the previous owner may be subject to a fine. And, I gotta say, at this point… I’m tempted to just wait it out and pay the fine.
Update:
Well, apparently Chris went and asked the Rona folks about their deck packages and conformance with building codes. Turns out they knowingly sell deck packages which don’t conform to our local building codes! Specifically, they use 2x6 joists and 2-ply beams with a 24” cantilever. How nice of them…
