alternate email

Looks like my lohnet.org mail server is down; don’t know when it will be back. Use my same username @gmail.com in the meantime. Update: of course they resolved it right after I finally got around to posting about it.

One hand clapping

If I asked you to “listen” silently to this page for 4’33”, would that be a copyright violation?

What if I attached a 4’33” long mp3 of silence?

If I recorded it myself, would that be a forgery or a performance?

What if I used a kazoo instead of a piano?

Would 4’34” of silence be a derivative work?

Would 15″ of silence, accompanied with this commentary, be an acceptable use excerpt?

Would the sound of one hand clapping be the appropriate sign of appreciation?

Time Flies

“Ethan here: Today marks the 44th anniversary of Candelstick Park tornado that struck Jackson. 57 people died and 504 people were injured.” —@16WAPTNews

I haven’t thought about that in years. My uncle was working there at the time; my aunt too, or maybe she was just visiting him. I vaguely remember them describing the experience. In any case, the “44th anniversary” part is what shocked me — I’ve been reminded that it happened nearly a half-century ago.

  Time flies like an arrow.
  Fruit flies like a banana.

I think I first saw that in a old Scientific American article about the difficulties in machine parsing of natural language. Lost in translation. A geek pun to me, since translation also refers to coordinate transformations: translation, rotation, scaling, skewing, … preserving topological equivalents across gross distortions, no tearing allowed. Ants. Moebius Strip II.

I sometimes envy those who have a sense of continuous, unbroken time. I imagine that for them events are like beads on a string, pages in a book, frames in a strip of film. Mention to them some event and they can provide context, cause and effect, sliding their finger along the curve and saying “see, this happened before, and this happened after”. The people who can always quickly answer those “where were you when such-and-such happened” questions that I hate. Steel Beach.

Like the “one, two, three, many” number concept attributed to some primitive tribes, time to me is only “today, yesterday, a while back, and a long time ago”. Time lies like pieces of a shattered mirror beneath my feet, glints and reflections, partial images fractured along random edges. Memory is a kaleidoscope filled with broken events, ever changing in random juxtaposition, tumbling in disconnected chaos. Mona Lisa Overdrive.

I C U

This is why I keep a PostIt over the lens of built-in cameras.

Cory Doctorow says:

According to the filings in Blake J Robbins v Lower Merion School District (PA) et al, the laptops issued to high-school students in the well-heeled Philly suburb have webcams that can be covertly activated by the schools’ administrators, who have used this facility to spy on students and even their families. The issue came to light when the Robbins’s child was disciplined for “improper behavior in his home” and the Vice Principal used a photo taken by the webcam as evidence. The suit is a class action, brought on behalf of all students issued with these machines.

Just WTF sort of delusional thinking gives a principal (or any official, for that matter) the idea that covertly monitoring a child at home is within the purview of his position?

Surprise, Surprise

Rands In Repose asks an interesting question:

I want you to think of the last time you were surprised. Good, bad, I don’t care. When was the last time you were really surprised? Got it? Ok, now think about the very first thing that you thought about the surprise. I don’t want to know how you eventually handled it; I want you to think about your instantaneous first reaction.

In the context of corporate bad news delivered in a group setting, he personifies the various immediate reactions with characters such as Dr. No, Raging Bull, the Handler, we’re Doomed, etc. He’s careful to note, in a “follow up” for each character, that these initial reactions to surprise are not necessarily the subsequent way the individuals actually handle the situation, merely how they begin to assimilate it: ” … I know this knee jerk reaction is not who they are, this is just how they react. Understanding these varied potential reactions is just the first part of digesting a surprise – it helps you understand what to expect so you [a manager] can begin to figure out what to do next.”

It’s not the fall …

… it’s the sudden stop at the end.

When your plane breaks apart at 35000 feet, you have about three minutes before you hit the ground at around 120 miles per hour. You might even survive. Dan Koeppel provides a morbidly humorous survival guide in Popular Mechanics’ “How to Fall 35,000 Feet—And Survive“.

According to the Geneva-based Aircraft Crashes Record Office, 118,934 people have died in 15,463 plane crashes between 1940 and 2008. Even when you add failed-chute sky divers, Hamilton’s tally of confirmed or plausible lived-to-tell-about-it incidents is only 157, with 42 occurring at heights over 10,000 feet.

Interspersed with accounts of actual survival, Koeppel offers some quirky suggestions for pre-fall training, including “banzai parachuting”:

The ultimate learn-by-doing experience might be a lesson from Japanese parachutist Yasuhiro Kubo, who holds the world record in the activity’s banzai category. The sky diver tosses his chute from the plane and then jumps out after it, waiting as long as possible to retrieve it, put it on and pull the ripcord. In 2000, Kubo—starting from 9842 feet—fell for 50 seconds before recovering his gear.

Something I didn’t expect was the huge number of comments arguing about the effect of body weight on terminal velocity. Clearly, a lot of people don’t understand the difference between free-fall in vacuum and in atmosphere.

Snow in Jackson, February 2010

snow-covered trees
We seldom see snow that amounts to anything, but this was enough to close schools and businesses.

I’ve posted a few pictures on Flickr.

I’m a PC, and ruining your battery was my idea.

It is ironic that Microsoft’s claim that Windows 7 will improve battery life is being countered by some users threatening class action lawsuits due to W7 ruining laptop batteries. At least since June 2009 (Windows 7 and the battery error “consider replacing your battery” –Microsoft Technet) testers were reporting this problem. Yet it continues, with claims, counter-claims, and finger-pointing. A couple of recent articles: “Microsoft probes Windows 7 battery problems” and “Windows 7 battery update: Still no conclusive findings“.

BTW, I always thought those “I’m a PC” ads were stupid. I’m a human and running Linux on my PC was my idea.
