  • Watch Out, Radioactive Man!

    Ok, since we are on the subject of things that fascinate me. How about radium glass?

    When I was little, I’ve read in some book about special red glass from which the red star on top of Kremlin was made of. It turns out that a little bit of radium must be added to the glass mix in order to get a deep red color.

    From here:
    When seen from below, from the ground, the stars do not seem particularly large, yet the points of each one are 3 to 3.75 meters apart. The lighting inside the stars is controlled from a room in the Troitskaya Tower. The framework of the stars is made of stainless steel and they are faced in special three-layer glass which is ruby-red on the outside and milk-white on the inside. Each star is lit by a 3,700 to 5,000 watt bulb and, to protect the bulbs from overhearing, cooled air is forced into the stars through hollow rods 24 hours a day. The stars are so designed that they can revolve smoothly in the wind.

    Oooh, oooh, look at this picture of the star being installed. Man….

    Anyways, back to my rant.

    Turns out that besides being popular as an ingredient in all sort of “medicinal” remedies, from enemas to pills, radium was used in many sorts of glassware. The color of radium impregnated glass has a very distinctive look. These days such items are called “Depression Glass” because it was very popular during the Great Depression or “Radium Glass”. A very distinctive feature of such glass is that it glows when exposed to uv light (aka black light).

    Here is what green radium glass looks like with and without uv light.

    Freaky, huh?
    My cigar ashtray is made out of the same greenish glass.

    There is also “Carnival Glass” that was popular in the 1920s. It is sometimes made of radium glass, but with a glaze made of iridium and other unobtaniums.

    There is not too much radioactivity in this glass, so it’s pretty much considered safe. I would not reccomend eating off it, but for collecting it’s ok. There are tons and tons of this stuff on eBay.

    Oh, I forgot to mention that I want to add a radium/phosphorus paint to the hour and second arms and numbers on my watch. The modern “glow in the dark” paints suck.

  • Live at the Palladium

    Hmm, this is interesting. Turns out that during WWII a lot of jewelry was made from palladium because platinum was unavailable. Check out a picture of Tiffany and Co ring in that article. Much better than most of the crap they are making now.

    Some pretty palladium jewelry can be found on eBay too.

  • Testing. Testing. 1. 2. 3?

    When programmers test their code, the need to come up with some kind of test data. And most programmers are not very creative (just as everybody else). Very often you can log into various websites with the login “test@test.com” and password “test”. I am afraid to even think about what test@test.com’s inbox contains. It’s a real email address you know, the emails don’t bounce.

    Here are some interesting test strings:

    Of course, everyone knows the famous “Hello, World” test string. I’ve heard that for the first time it appeared in the bible, but I am not sure.

    The other most famous test strings are “foo” and “bar”, which apparently come from foobar, which is derived from WWII slang. FUBAR is a relative of SNAFU.

    A professor that taught VB in college told us, that about the time he was developing a database application for a hospital. His favorite test person was James T. Kirk and his mates, and during testing the poor captain got every imaginable sort of ailment. With funny comments.

    When I worked at iXL, our tech lead, a German by the name of Lothar, liked to use a string “4711” as most people use “foo”. Once, in a meeting he asked if anyone new why he was using “4711”. He was pretty surprised that I new what “4711” was. “4711” is what some of you may know as Koeln Water, which was the first commercially produced perfume. That’s where the term “cologne” came from. And “4711” is the number of the building where Koeln Water was produced.

    I use “1729” for my testing needs sometimes.

  • One Ring To Bind Them All

    After I lost $30 pounds on Atkins diet my wedding ring started to slip off my finger. Of course, I am not Frodo, and wearing it on a piece of string was not an option. I used to leave it on the dressing table a lot, and finally it disappeared. Who stole Precious is not clear, but Tilde the cat is a likely suspect. So my wedding band is hopelessly lost.

    It was a titanium ring. It looked like this:

    Interestingly enough, the company that makes these rings is located in Canada. I wonder if they were inspired by the Engineer’s Ring.

    I have a somewhat unhealthy fascination with titanium. I love that metal. SR71 Blackbird planes, Akula class subs, and if you are a Star Wars geek, TIE fighters are made mostly of titanium. I own a titanium watch and eyeglasses frame. I used to have a titanium pda case, but I lost it too :( Titanium is almost indestructible, but easily lost.

    Well, now I need to replace the ring. I am thinking of choosing a different, fancier design. Probably one of these.

    I was also thinking about a more exotic material for the ring, like iridium, but nobody makes them.

    By the way, titanium rings are machined out of a single block of titanium. You can’t really smelt titanium, so resizing the rings is out of the question. Imagine how much skill is needed to machine interlocking rings out of a single block:

  • Gentlemen, Start Your Engines!

    mentioned in a post that his ship used to have gas turbines while in military service, but then was refitted with diesels. I realized that I did not know how a gas turbine engine works. I new that jets use turbines, but not much beyond that. Well, http://www.howstuffworks.com came to my rescue.

    The article mentioned, that there is a surprising amount of activity in home built gas turbine engines. Surprising doesn’t even cover it. “HOLY CRAP” is more like it.

    Check this out:
    Mike’s Home Built Turbojet Engine
    Larry’s gas turbine jet engine
    John Williamson’s gas turbine and pulse jet stuff!
    And that’s just the first page from google!

    The dudes who make ray guns out of microwave magnetrons pale in comparison.

  • What, Again With The Fishing Rods?

    If you’ve been reading my journal, you probably know that I like nice things. Consumerism is not foreign to me at all. Some of you are probably are sickened by my consumerism and are just sticking around for pretty pictures of New York that I take. In any case, I am going to brag a bit about my fishing rods.

    Mind you, custom fishing rods that I like so much do not help me catch more fish. In fact, for some reason, the biggest fish that I ever caught were taken on the crappiest rental rods.

    What does it mean for a rod to be custom made, you ask? Well, fishing rod industry is somewhat similar to the PC industry. You can either buy a pre-assembled rod, or buy all the same ingredients and put it together yourself. Of course, it takes much more skill and know-how to put together a fishing rod. A rod made by an artisan will be much better than a factory assembled one. The master will find the optimal bend of the blank and affix the guides so that you can cast a bit further, the balance will be a touch better, there will be a bit more sensitivity (all compared to a factory assembled rod made from the same ingredients).

    But one thing that the custom rod will have that will instantly set it apart is the butt wrap. Butt is the bottom part of the rod of course. :)

    What is a butt wrap? It’s a pattern made with tightly woven threads. These patterns are defined by hundreds or thousands of overlapping threads, often wound one at a time. Designs can be simple that take an hour or two or super complex ones that take days of concentrated work.

    There is a book about this and even software called VisualWrap for making the designs. No, it’s not a part of Visual Studio :)

    Some designs, like this dolphin fish , work kind of like pixel graphics.

    Others are complex geometric shapes.

    The three nice rods that I own are not really custom, although high quality. Buy I’ve had them custom wrapped, although with rather simple patterns. I’ll take pictures sometimes, but right now I can’t figure how to minimize glare from the transparent epoxy that covers the pattern.

    I am about to buy two real custom rods, and I already picked a pattern for the wrap. The first pattern is going to look like :

    Take a look at the rest of this guy’s examples here.

    And a second one is going to be a simple solid diamond wrap modeled after Samurai Jack’s sword.
