Angels and Demons

I'd always suspected that those books everyone keeps raving about, The DaVinci Code, and its sequel Angels and Demons were, shall we say, perhaps less than factual, but this really cinches it for me.

Q: Does CERN own an X-33 spaceplane?

A: No.

Storms

This week hasn't been especially good for me, but I'm somewhat amused at the fortuitous timing of last night's storm. The power got knocked out briefly last night, and when I came home I found my computer shut down with a note from my roommate:

"Your computer was making beeping noises so I turned it off."

Sure enough, it's making an awful siren noise on boot, the kind of sound I associate (after years in the IT industry) with sheer terror, expensive purchasing orders, and CPUs melting in some kind of perverse recreation of a Salvador Dali painting. The whole thing is rather suprising, considering the surge protector and decent power supply. I'm running it down to the SCIC as soon as I can get a cart, but I don't really know what broke, or where I can get replacement parts from in time. Did I mention this is the start of finals week? >_<

As a result of all this, I'm going to be off of IM networks and checking my mail infrequently at best, until I can get my computer fixed.

Fixed!

W00t w00t! Looks like it was just the bios that got screwed up. A quick reflash did the trick. There were a few loose inodes on fsck ("/ has not been checked in 46091 days, check forced"), but I can attribute those to the power failure.

Now, on to the paper of doooom!

Snow!

It's snowing today: dry flakes swirling down through the cones of light from the street lamps. -17 degrees celsius wind chill, says the observatory's weather station. Walking to work at this hour of the night is an exercise in self-control, moving from step to step with care to avoid slipping on the icy walks, squinting to keep the flurries of snow from smacking into the eyes, and keeping hands tightly within pockets to keep the frigid air at bay.

Really, though, the snow and the cold make me happy. The vortices of air swirling around buildings whips the flakes into an intricately fractal frenzy, and the biting cold is a reminder of how crisp the world can be, absent of warmth. Tomorrow morning, I look forward to opening the door onto a landscape transformed into smooth forms of black asphalt, white snow, and grey stone and sky. Black and white has a certain, quiet, eloquence.

Stargazing

It's 11 PM, and once again I'm stargazing on the hill of three oaks. There is no trace of human activity here--only the full moon for light, the soft sound of snow crunching beneath my boots, and winds slipping fiercely past my coat. An hour at these temperatures concentrates the mind; one's world contracts to the blazing, tingling flame igniting in one's fingers and toes from the cold, the taste of blood flowing from frozen, cracked lips, and the howling of the wind against one's face, slowly numbing into a frostbitten simacrulum of one's former physiognomy. At the same time, there's nothing else like looking into this white expanse, tinged blue by the cold light of the moon and stars; to wonder at the majesty of the trees which stand here year after year, etched in black against the sky; to look up, and fall softly to the ground at the sight of ten million brilliant and specific stars.

I lay here, and wait to become a part of the landscape.

Back Home

I guess I'm back. Woke up Tuesday at 7:30. 11 hours of cars, airports, airplanes, half-hearted goodbyes, J.D. Salinger, The Samples, Neil Gaiman, and Something Corporate later, I arrived (somewhat displaced) at the doorstep of my old house. A lot's changed since I left. The walls, once a gallery of landscape and family photographs, are home to spare collections of hooks where frames once hung. The plan is to re-paint most of the interior walls, hence the spare decoration. The back door, the one that never closed properly, is replaced as well. All the doorknobs feel small here.

Writing the title of this post makes me wonder really where home is. I don't have a permanent address, really, just a probabilistic chance of successfully being reached. I live a quantum life, shifted by finite yet predictable uncertainties.

Stopped by my old school today to say hello to friends and teachers. Meetings were brief but enjoyable--the security personnel ordered me (contrary to official policy) to come inside, which I gladly obeyed. Mark and I went out to Sushi afterwards, which was amazingly delicious. ^_^

Went to my favorite local music store as a result of my evil habits of digital media piracy, and bought Kaki King's album "Legs to Make us Longer". It's a different kind of music than I've been listening to lately: no real melody, or strong emotion, but it grabs your attention with skill, complexity, and character. I don't know how to describe her style, but there's a guitar, and it's impossible not to listen to.

One thing I've really enjoyed about the last two days has been the ability to read--not a technical manual, not a news article, not an essay or thesis or comic strip, but real books with plot and characters and description. I didn't like most of Salinger's short stories, but "Catcher in the Rye" was very moving, in a strange, poignant sort of way. Right now I'm reading "American Gods", which is good for entirely different reasons.

I'm waiting to hear back from my employer, but it's entirely likely that I won't be working until Monday. Feel free to stop by and say hello. :-D

Thanksgiving

I am thankful for good friends, fun, educational, confusing, and generally unforgettable college experiences, a warm (comparatively speaking) house, cats, music, large quantities of delicious food, a job doing what I love, bicycles with functional pedals and brakes (The Brick, I'm referring to you here), photography, and hugs.

Work

So I'm back at work again, but my job has changed. No longer am I the stealthy IT ninja, whose responsibility it is to replace components the day before they they break, anticipate obscure printer errors that could bring ruin to the marketing department, repair desktops while their users are out for a cup of coffee, and arrive silently in an employee's cube before they hang up the phone. I'm still messing about with the network monitoring system (especially the TAP gateway, which fails silently half the time), but my official job is now within the realm of support. Working against time on a laptop with a failing hard drive, I'm writing a support web site with the Ruby on Rails framework which will interface with our customer relations management service.

Let me tell you this: Ruby. Is. Amazing.

I've set aside this week simply to learn the language and the framework, and the sheer amount of magic in Rails is astounding. I'm not entirely sure I like the eRuby template system for views, but the astounding simplicity of ActiveRecord makes the whole thing worth it. The way it manages relationships between tables takes all the work out of SQL management... and some of the methods available for model objects are startlingly useful. Data validation rules make a lot more sense when implemented as a part of a smart model object, rather than being controller-specific.

Then there's the controller logic, which when coupled with RoR's url_for() logic solves the problem I've been facing with Ragnar since the beginning: how to relate the URL to the scripts which interpret them. I've pushed the logic into the XSLT templates and allowed the designer of those to create their logic thus, but that methodology makes it difficult to dynamically generate URLs--they have to be created by the controller and passed to the template as parts of the XML document.

In any case, learning the Rails framework has been a lot of fun, and I'm looking forward to starting the real work next week.

You May Fire When Ready

Okay, this is officially the coolest peripheral ever.

On the not Unvague Modern Lexicographical Modality of Communication

In 1946, George Orwell wrote an essay on the pitfalls of English prose, describing what he considered to be the common mistakes made in modern writing. Politics and the English Language identified dead metaphors, over-used phrases, and vague diction as habits to be eliminated from writing, for they tire the reader, confuse the meaning, and destroy the specifics of one's intended message. Whether purposeful or accidental, such errors have not yet been eliminated from the English language: 60 years later we still make the same mistakes, albeit in slightly different forms. While most writers keep their prose admirably clear of such obstructions, passive, vacuous, and needlessly complex sentences cloak the modern world of bureaucracy and politics in a haze of pretentiously irrelevant verbosity.

Take the first of Orwell's charges: the dying metaphor. Some of his examples of have now faded from use, like "ring the charges on" or "take up the cudgels for." After all, few people fight with cudgels nowadays. However, some of these phrases remain in circulation. "Toe the line" has become embedded in our vocabulary to the extent that it fails to arouse any trace of visual imagery. One has only to examine any political statement to encounter these tired phrases being trotted out once again for display. We speak of "cutting off ties" with other nations, or refer to America as "a shining beacon" of democracy, and no one thinks anew. The problem of dying metaphors hasn't gone away, but merely shifted to a new collection of unimaginative analogies.

Similarly, the reliance on verbal false limbs and the passive voice has not diminished with time: these appear with frequency in political, bureaucratic, and scientific writing. Compounding simple verbs and nouns produces the illusion of objectivity and sophistication while obscuring the real facts, as this excerpt from the FBI's about web page demonstrates:

Since the tragic events of September 11, 2001, one week into his term, [Director Mueller] became responsible for spearheading what is perhaps the most extensive reorganization the FBI has experienced since its conception.

Note the cumbersome use of "became responsible for spearheading" in place of "spearheaded". This operator takes the most general verb in the English language—to be—and attaches a collection of loose adjectives and verbs which confuse the reader. Also observe the semantically vague qualifier "what is perhaps the most", and the tacked-on phrase "since its conception." These false verbal limbs do little to clarify the meaning of the sentence, but are included either out of habit or a desire to appear intimidatingly well-educated.

Likewise, the habit of euphemism has infiltrated the language of our legislation and corporate policy to great extent, replacing unpalatable words with vacuous terms bearing little relation to the original. "Downsized" is a beautiful example: a verb constructed from a noun and adjective to replace "fired". Of course, English speakers are remarkably adaptable creatures, and the phrase "downsized" now elicits a twinge of fear throughout the corporate world. To compensate, even more bizarre phrases have been coined: employees can be "repurposed" or "released", and the march of progress clamors on. Sometimes, euphemisms can completely reverse the meaning of a term—as in the case of the "Clear Skies" act, a bill which allowed for higher levels of atmospheric and water pollution. Surely our capacity for euphemism has not diminished in the years since Politics and the English Language.

At first glance, Orwell's charge that politically charged words are 'meaningless' seems diminished in our time. After all, communism no longer threatens the United States as it did in the 1930s. The terms 'fascism', 'realistic', and 'socialism' have lost their visceral connotations, and we use them with relative objectivity. However, the distortion of words within political speech remains a common practice. When asked about the United State's policy of rendition-—capturing individuals suspected of terrorism, flying them to countries known to torture prisoners, and holding them for months without due process of law--National Security adviser Stephen Hadley responded:

I think the President has been pretty clear on that, that while we have to do what we -- do what is necessary to defend the country against terrorists attacks and to win the war on terror, the President has been very clear that we're going to do that in a way that is consistent with our values.

Note the immediate interjection of "what is necessary to defend the country against terrorist attacks" and "to win the war on terror." These phrases do not address in any way the term or process of rendition. "Defense against terrorism" has become a blanket phrase in our political lexicon, used to justify anything from war to wiretaps to airplane screening lists. "Consistent with our values"? If freedom is an American value, is imprisonment consistent with freedom? Fuzzy terms like "freedom" and "values" provide no concrete information, but make us feel somehow better about the subject. These are precisely the sort of meaningless words that Orwell spoke out against.

One look at any press release, office memorandum, or political address will reveal that Orwell's assertions about the English of 1946—-far from being obsolete—-are eerily applicable to our writing today. We consistently confuse, mislead, and distract our readers with dying metaphors and malformed operators, euphemisms, and meaningless words. While all of us should heed Orwell's advice on writing clear and meaningful prose, few will. It remains our task as informed readers to identify and compensate for the habits of obfuscation in the bureaucratic style.

I can't make this stuff up. The security blotter is a wonderful thing.

Software Image Focusing

This paper explores an interesting technique for measuring the angles of light rays at each point on a CCD, by using arrays of small lenses. There's a decrease in the resolution of the image, but the data captured can be recomputed to generate photographs focused at varying depths in software. This also means that photographs can be taken with larger depth of field without changing the aperture. I'd really love to have a camera that could do that...

Atom Feed

I've written an Atom 1.0 feed for Ragnar. Other changes include a more organized system for passing metadata, improved image thumbnail layout, better cross-platform support, and new graphics. The administration interface still needs a lot of work, though.

Computer Breakage, Part 3

To recap the events of the past few weeks:

Aphyr.com suffered a brief span of amnesia due to faulty ram, which has since been replaced. Everything seems to be working great now. In the meantime, I've started working at Sys/Net, which is much more fun than tech support. It's chaotic, unsupervised, and way the heck too much fun. Running around with cable testers, patching in ports and messing around with DNS is my kind of job. d=('_`)=b

To my dismay, my northbridge fan started buzzing obnoxiously just prior to shutting off completely. To prevent the premature conversion of my motherboard to slag, I've ordered a replacement cooling fan. ABIT (the manufacturer of my board) gives away free replacement parts, but doesn't have this particular one in stock. Instead, I bought a Cooler Master chipset cooler. It should arrive in a couple of days.

In other news, classes continue to be hard, life is awesome, and the weather is beautiful and sunny. Wish you were here. :-)

Snakes!

Today was a great day in Psych. We were discussing the formation of phobias (specifically, classical-conditioning models of phobia response creation), and went over some common phobias like:

  1. The fear of flying
  2. The fear of spiders
  3. The fear of snakes
  4. The fear of peanut butter sticking to the roof of one's mouth.

Numbers 1 and 3 gave me a brilliant and wonderful idea.

Me: "Is direct association the only way phobias can be created? Or can secondary conditioning take place as well?"

Professor Burke: "Could you give an example?"

Me: "Well, let's say I have a dreadful fear of, shall we say, snakes. And I went on a plane trip, something I'm ordinarily fine with. Now what if, on that plane, I was to come into contact with one or more snakes, and that freaked me out. Could a form of secondary conditioning or stimulus generalization take place whereby I develop a fear of flying?"

Professor Burke: "Well, let's look at the classical con...wait, in fact, isn't there a movie made about that? Snakes on a..."

Class: "SNAKES ON A PLANE!" *laughter*

Professor: *hangs head and sighs*

It was amazing. I received an e-mail recently from my professor mentioning the joke, too.

Nice question last time (snakes & planes). Caroline and I were laughing about it later on as well as in class.

Good times. :D
