Can you give us a brief overview of what you've done?

To answer your question, I'm using a big black box with a variable speed motor attached to an alternating beater arm. Each tag is spun around within this black box by this beater arm inside a metal colander with small holes of varying sizes. Those tags not marked as safe have holes of appropriate size that can be found in this colander. Those marked as safe do not have such holes. As they're spun around, centripetal force pulls them out through the hole sized appropriately for the given tag. What's left is then poured out into a baking tin sprayed with 3 in 1 oil, baked at 12,000 degrees kelvin for 3.4 nanoseconds and promptly stored in the database to cool. Serve chilled, neat, warm, or hellfire. Serves an unlimited number and never spoils.

Wouldn't a teflon coated ceramic work better and resist corrosion?

I experimented with teflon and ceramic, both together and separately. I abandoned them both for separate reasons.

I found that the sharp ends of the tags would scratch nearly all the teflon coating off the colander after only one run. This resulted in excessive long term memory loss in those the final product was served to, hence the temporary increase of same subject questions on thelist in a relatively short period of time.

In my experiments I found that the initial torque requirements necessary to bring the colander up to speed was causing undue stress on the motor due to its weight. The advantage of inertia at that point would have warranted keeping it if it hadn't been so expensive, not to mention there wasn't enough room in the current design of the black box, to install a set of counter-action, retro-motion brakes. without them the colander would come up to speed, spin out the mash in milliseconds and continue to spin for hours. This resulted in unnecessary spilling when attempting to feed the next string to process. We were losing data bits from unpredictable spots in strings until we figured that one out. Some of the secrets of the universe will never be recovered because of that mistake.

What's the leverage ratio of the arm?

It's actually a variable ratio leverage arm achieved by a parallel coupling between the motor drive arm and the fixed arm on the beater. Depending on the thickness of the string, the arm can adjust its pitch to match.

You have no idea how much rethinking we had to do just to test this thing. We had to throw all of our testing methodology out the window.

Are you using needle bearings or cartridge?

It's actually using something called a polymorphal-floatfit. maybe i'll write an article about that actually. It's pretty complex.

I would think there would be some concern with the possible under-torque in high-content filtering

Fortunately, this device is nothing more than an object that can be instantiated for any number of requests. we even recently fitted it with an attachment that would take care of its own cleanup and storage. All you have to do is install it and it does everything else automatically. Unfortunately we forgot an off switch and it can be pretty protective. So, now that it's installed we're basically stuck with it.

Thanks for taking the time to speak with us.

Sure. Can I go now?

Adrian has years of experience in graphic design, web design and multimedia design, as well as extensive experience in internet commerce and interface design and usability. He has been developing for the World Wide Web since its inception, and working the design field since 1993. Adrian is a founding member, board member, and writer to evolt.org. In addition, Adrian sits on the Digital Media Advisory Committee for a local SUNY college and a local private college, as well as the board for a local charter school.

Adrian authored the usability case study for evolt.org in Usability: The Site Speaks for Itself, published by glasshaus. He has written three chapters for the book Professional Web Graphics for Non Designers, also published by glasshaus. Adrian also managed to get a couple chapters written (and published) for The Web Professional's Handbook before glasshaus went under. They were really quite good. You should have bought more of the books.

A Clarification

I just want to point out that 12,000 degrees kelvin is only an estimated temperature. As I understand it, the actual temperature was most likely slightly lower.

Oops

That may have been a typo, I'll have to check with Jeff, assuming he responds to my furtid emails...

annondized is the way to go

Submitted by aericks on April 1, 2001 - 11:18.

I set this up on my own server using a box made of annondized aluminum and it all worked just fine. Although, I did find that I had to strip unnecessary </td> tags which for some reason kept sticking to the edges. The upside of this is that the ground </td>s make an excellent white sauce, add a splash of wine and serve over pasta -- yummy!

Other side of the Altantic

Submitted by paulnattress on April 2, 2001 - 07:42.

In the UK we'd just use a sieve. By which time the US have spent 6 years developing it into the contraption described above. Then we'd still use a sieve and BT would claim the patent on it. And charge us by the minute. But hey, we've got the National Health Service in case we injure ourselves. Which nicely takes us back to waiting 6 years.

Patent infringement

Submitted by Ratface on April 4, 2001 - 13:11.

I think you'll find that I've already got a patent on a very similar method (Patent # 666999GUGUGU321 - Method for sieving diverse web content at high rotational velocity). You'll be hearing from my lawyers tomorrow!

Colors

Submitted by ucahg on April 13, 2001 - 06:07.

I think that colors should be allowed in the articles definetly and maybe in the comments. Whether is be <font color="red"&rt;</font&rt; or a special tag created for the purpose, such as [color=red][/color]. This would be good for, if there was code, to color code it and make it easier to understand.

Those are supposed to be > symbols, not &rt;

colors...

Submitted by aardvark on April 13, 2001 - 06:42.

You might want to post that comment over at the sister article, Inside the evolt.org Rebuild: The HTML and CSS. You can also see why we've disallowed colors.

In the meantime, feel free to offer any suggestions on how to get the polymorphal float-fit action to adequately parse out predefined colors. Without installing a multi-filter polarized lens and coupled photon detector, I don't see how we can run those tags without slowing the action of the arm to almost a crawl.

color problem solution?

Submitted by judah on April 23, 2001 - 12:44.

You might be able to solve the color problem by utilizing wavelength-specific absorbtive materials. Provide a multilayer material with a layer for each color ([color=red][/color] is about 320nm if I recall) and a reflective material (or transmittive depending on colander design) at the lowest layer. Voila. Now that I think about it, you should probably use a transmitting matterial at the lowest layer to avoid red-shifiting the reflected light and creating non-websafe colors.
