Radioactive Mudworms (1991)

Monday, May 23, 2011 

I animated Radioactive Mudworms in 1991 with a program called Infini-D.  The soundtrack was courtesy of David Lenat. It was first published on the QuickTime Beta CD to Apple Developers and then in 1992 re-rendered on a Mac IIfx 40mhz 68040 with a massive 16MB of RAM in this version for the FigTime commercial CD. As I remember it, this took about a week to render on that massive machine.  I’m pretty sure I ray-traced it, but I output to “thousands” of colors as required by the CODEC and so it is hard to see some of the details.

The file is so old that the “animation” CODEC (RLE) used is no longer supported.  I had to boot my old Mac 8600 to read the CD and convert the file to uncompressed, so I could re-compress it with a modern version of QuickTime.  I was greeted with an alert that my last backup was in 2003.  Time flies, but the mac still runs and that OS 9 operating system is still a nostalgic pleasure.  I used it regularly from 1987-ish to 2003-ish, and it is still the OS I’ve spent the most hours in front of.

Digital obsolescence is starting to consume my work history as the past has already eaten the DECstation streaming tapes my MIT work was “archived” on.  Of course, I can still read my preschool notebooks and I’m sure I could still read my parents notebooks.

Infini-D was my favorite 3D program of the time, though it was supplanted by StrataStudio 3D, Turbo-3D, and finally ProEngineer. It had a nice combination of modelling, rendering, and animation tools and was part of a brief “golden era” of 3D most remarkable for VPL and the existential excitement around Virtual Reality, which comes and goes every decade or so as a new generation reads Snow Crash and thinks that they, too, could be Hero Protagonist or Raven and have a chance with someone like YT if only the world truly adopted VR.

I was reminded of Radioactive Mudworms as I spent the weekend trying to teach the basics of video compression remotely to some coworkers who may not have been born when I made this.

The video was encoded at Valley Green 6, in the cube farm for the Advanced Technology Group at Apple.

A very old .mov version: https://gessel.blackrosetech.com/wp-content/uploads/2011/05/Radioactive-Mudworms.mov

And because technology, here’s an AV1.webm version for the next 32 years given that VP9 may be replaced once Apple gets on board, if they do.

 

BTW, the conversion is

ffmpeg -i Radioactive-Mudworms.mov -vf scale=-1:250:flags=lanczos  -c:v libsvtav1 -pix_fmt yuv420p10le -preset 0 -svtav1-params tune=0 -b:v 0 -crf 22 -pass 1 -an -f null /dev/null && \
 ffmpeg -i Radioactive-Mudworms.mov -vf scale=-1:250:flags=lanczos -c:v libsvtav1 -pix_fmt yuv420p10le -preset 0 -svtav1-params tune=0 -b:v 0 -crf 22 -pass 2 -c:a libopus Radioactive-Mudworms-AV1.webm

On the Road in Iraq

Tuesday, May 3, 2011 

We took a very nice tour from Baghdad to Basrah by car. The countryside is pretty amazing, from the relative lushness of the fertile crescent to the desert sands of the south to the marshes of the deep south and the distant flare gas fires on the horizon.

Stupidest Dialog Box Evar

Monday, May 2, 2011 

This is the dialog you get in thunderbird if you end up with multiple operations running – such as if you “download all mail” twice without realizing that a previous iteration is still running.

I could not possibly care that a background operation failed (and should be patiently and silently waiting until the other operation finishes, then try again itself; maybe, just maybe letting me know if I’m going to quit or shut down how many operations are pending in a single dialog).

But not only could no user ever care about the information provided by this dialog, it is done so as a modal dialog that steals focus. ZOMG, that’s the sort of user-hating bad design that makes people abandon a package.

Cordless Mice?

Tuesday, April 19, 2011 

Apparently the FAA has decided that cordless mice with their nanowatts of transmit power represent a risk to airplanes. Discussion forums contemplate that the FAA is concerned they could be used to trigger explosives in the hold (when they outlaw cordless mice, only outlaws will have cordless mice). Perhaps they found a cordless mouse that used a spark gap transmitter and so banned the whole class.

BTW, this is being posted via gogo inflight, the wireless radio on my laptop also uses 2.4ghz unregulated and could be 200mw and who knows who made it (same frequency band, 3 or 4 orders of magnitude more RF power).

While I’ve dealt with worse, I am on occasion reminded of just how awesome the air bureaucracy in this country really is.

On the plus side, the new digEplayers on the PS flights are pretty nice and a big improvement.  Plus they actually run on battery now.

Recursive, Incremental FTP

Thursday, April 14, 2011 

Looking for a way to transfer an entire website, including subdirectories, from one server to another directly, I found this summary https://stackoverflow.com/questions/113886/how-to-recursively-download-a-folder-via-ftp-on-linux of a great tool: NCFTP.

The client supports recursive “get” and “does the right thing.” It silently handles broken symbolic links, downloads all the files in the source directory including subdirectories, and even better, smartly does an incremental update on repeat saving a lot of time, bandwidth, and tedium.

Great utility that makes systems admin just a little bit easier. From now on, part of the default install.

Science Experiments

Monday, April 11, 2011 

Home from Afghanistan to find some very interesting science experiments waiting for me.

Yogurt residue grew into a lovely pattern of furriness. Almost makes you want to pet it.

Coffee beans should have been fairly sterile after making coffee, so perhaps the mold there was donor from the yogurt cup.

Whatever was left over in the plastic container seemed to seed a variety of mold types.

A strong dose of bleach and some scrubbing got everything sterile again.

Kandahar

Sunday, April 3, 2011 

KAF would be very nice base, quite photogenic. Aircraft take off night and day, the fighters taking off on afterburner are like a free fireworks show every night. The A10s are some of the coolest planes ever and there aren’t that many places to see them any more.

The downside to the base is the Poo Pond. It is, perhaps the most famous feature of the base. It was built by the Russians, a gigantic open cesspool.

The smell… the smell is truly incredible. Imagine being locked in an overfull outhouse on a hot, windless day, but spreading downwind for miles and inescapable. It is one of those things that is better experienced vicariously.

But at sunset, aside from the retching stink, it is quite photogenic – the black, viscous liquid is mirror like, still and reflects the sunset just beyond the bio hazard signs.
