Space Gridlock

After the collision of two polar-orbit satellites this week, it is worth the time to take a look at just how crowded the ‘technosphere’ is getting. This graphic presents an interesting perspective of the situation. But, in reality, if the the relative size of satellites in this picture were in the same scale as the planet, none of them would occupy even a single pixel – that is to say, they would be invisible.

Beehive of Satellites

From today’s NASA Image of the Day:

A Beehive of Satellites

The launch of the first artificial satellite by the then Soviet Union in 1957 marked the beginning of the utilization of space for science and commercial activity. During the Cold War, space was a prime area of competition between the Soviet Union and the U.S.

In 1964 the first TV satellite was launched into a geostationary orbit to transmit the Olympic games from Tokyo. Later, Russian launch activities declined while other nations set up their own space programs. Thus, the number of objects in Earth orbit has increased steadily — by 200 per year on average.

The debris objects shown in the images are an artist’s impression based on actual density data. However, the debris objects are shown at an exaggerated size to make them visible at the scale shown.

TASER XREP Shotgun Stun Projectile

While a TASER XREP might be a good non-lethal solution to a home invader, I would recommend the next round in the magazine to be a standard 12-gauge double-ought round – Just in case.

Taser XREP

How Stuff Works has a new article on this interesting technology.

Creating a device small enough to fit into a shotgun shell casing but powerful enough to incapacitate a subject was no easy task. The development team at TASER had to find a way to balance power with size. Not only did they need the device to travel farther than a standard TASER, but also to have the right amount of mass. If it had too little mass, it wouldn’t travel far enough. But if it had too much mass, it could become a deadly projectile rather than a non-lethal solution.

UPDATE: This has nothing to do with this post, but deserves your attention. Gun Rights Examiner has details about a teacher getting suspended for having a picture on Facebook while holding a gun. Recommended reading for sure.

We’re in the Money Now!

big moneyLast month, we finally had our landline telephone service discontinued. I called AT&T to inform them that their services were no longer needed since we each now have a personal wireless device that does everything (and much more) than their service can provide.

I was reluctant, at first, to discontinue the service, since it has been our telephone number since before 1979 – we kept the same number from the previous owner when we moved here.

But, after doing all the trade-offs, it just had to be done.

Then, after all the smoke settled, I got this fantastic refund from the accounts payable folks at AT&T. Woo Woo. Where will I spend all this money? Maybe a lead 7½ shot ball in a 12 gauge shell? Yeah! That’s a great idea!

Tribute Counter

A couple of days ago, our server upgraded the operating system, which managed to break some of the scripts I use for this site. It turned out to be a good thing, because I re-wrote some of the scripts using more up-to-date features. One of those features is AJAX or Asynchronous JavaScript And XML which is said to be “JavaScript on Steroids” by some.

ttrib-stats.jpgI had been wanting to make the readout of the hit counter on the “Never Forget” tribute a dynamically-updated widget, so I went to work and made it happen. Now, when you look at the tribute statistics in the sidebar, you will see the counter update in (more or less) real-time as the tribute is served up to yet another website. The rate at which it increments is higher during day and evening hours in the U.S., so I presume most of the people seeing it are in the western hemisphere.

As of this posting, the counter is about ready to roll past 48 million hits – wow!

Happy Face Fireworks

“It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more.”

— John Adams to Abigail Adams, Philadelphia July 3rd. 1776

While watching the fireworks display at a nearby park last evening, we witnessed a lot of great effects, including a happy face. Check it out in the video.

I got curious about what effects there were out there and so I looked in WikiPedia for some answers. I was amazed at the many types of effects applied to modern fireworks displays. Among the many effects there is the ring effect; the happy face is a derivative of the ring.

I also found the quotation from John Adams at the top of the WikiPedia article.

Barbie’s Piano

barbie-piano.jpgWhy is this Barbie Piano special? Well, because, this one has provenance.

You see, back in 1980, I worked for Mattel Toys in Hawthorne, CA as an engineer in the preliminary design department. I designed electronics for prototypes of all sorts of toys, including remote control cars, self-guided racers, sound effects for a hot wheels airborne transport toy, and the piano sounds for Barbie’s Piano.

I collaborated with another prototype designer who did the mechanical development. My job was to develop an electronic piano sound. I actually got a patent for the ‘decay modulator’ circuit, which was the heart of the semi-realistic sound. When a key is struck, the tone fades out gradually just like a real piano.

When it came time to demonstrate the toy to Mattel’s president, we brought the model in, sat Barbie down on the bench and I made my first and only professional musical debut as I plunked out “Somewhere Over the Rainbow’ using Barbie’s hands on the keys.

keyboard.jpg“I love it,” said the president as he clapped his hands with approval, “let’s get it into toy development and go with it!” After the piano went into production, even though I was not working at Mattel, they called me in and gave me this one when it was new.

I saw an original Barbie Piano on eBay today with a selling price of 160USD. And that was without the bench and the instruction/songbook. I imagine that this particular one might be worth a bit more with my signed statement about its development and my role in it.

While this one has never been owned by a child, I used to indulge my granddaughters and let them play with it. As a consequence, it’s not completely pristine and the little wands used to play the tiny keys are missing. A mistake, to be sure, but you should have seen the pride in their eyes knowing granddad invented this toy.

Point and Click

Please don’t associate the “point ‘n’ click” terminology with computers – unless the *&^$@ computer dies and just might make a better target than a tool. Come to think of it, even though the hard disk died, it’s possible it could be recovered and read by unauthorized persons. Any personal data on the hard drive should be destroyed.

Hmmmmm – a remote area, the Glocks and this defunct laptop – it might be fun.

Point and Click

Naah – I’ll just remove and destroy the drive and take the rest to the recycler.
