Agency Happens

Early this morning the following slogan came into my liminal thoughts:

Agency Happens
This intrigued me.  What I had in mind was the sociological concept of agency, i.e. the ability of people to take action to further their own interests. Consider it a response to the more well-known phrase, "Shit Happens". The concept it conveys is "You make your own shit."1,2

Syntactically it looks like a bumper sticker, so I decided I'd put the following on Facebook:

Today's thought: 
Agency Happens
(If you put that on a shirt and sell it I want my cut.)
This amused me because here I'm contradicting the concept I'm presenting by abnegating my own agency in declining to produce and market the shirt myself.

While chortling at my cleverness I realized there's a second interpretation following the principal/agent distinction in behavioral psychology that essentially says decisions are easier to make for, and when made by, other people, as the indirection diminishes the feeling of responsibility and subsequent dithering about what to do.3 In essence, if blame can be directed towards another the shame of making a bad choice is lessened.

For that I'd have wanted something more like this:

Agency Happens
(If you put this on a shirt and sell it I want my cut.)
which is exactly what one would want to see on a shirt, both in formatting and in change of the pronoun. It might even be more understandable, as there are companies that act as agents in producing such things. But the presentation weakens the original concept, which I still like best.

Sadly, social media technology failed me in both cases because I couldn't see how to get centered or quoted material into a Facebook box in the time I had available. In fact, I'm not happy that this blogging software doesn't let me control italicization within the quote blocks.4 Nonetheless, here it all is.

1 Within structural constraints, of course, since full agency is a privilege of the dominant members of a society.
2 No, I'm not going to pursue the semiotics of that phrase, although it's worthy of consideration in its own right.
3 "Am I over-analyzing? What if I'm over-analyzing!" Yes, I thought you'd understand.
4 No, I'm not going to override the style sheets to do so. I've already spent too much time trying to make footnotes that I'm pretty sure won't work in the final output.

DIY problem solving

Last summer, when I had an arborist out to deal with a huge dead branch on the silver maple in the back, he pointed out that the lawn care folks' weed whipper was scarring the trunk of an ash tree in the front. He suggested I lay down mulch around the base of the tree, to stop things from growing so they wouldn't need to do that.

So this spring, I determined a reasonable diameter, calculated square footage, and hied off to Menards for ten bags of mulch and some edging to contain it. I then marked the perimeter with six garden stakes and spent an hour with a mattock taking off the grass, trying not to cut through the surface-level roots of the tree. Fortunately, this was April, and it wasn't too hot out.

At that point I found out that the edging needed some stakes I hadn't been aware of, and was told by a helpful neighbor that I should also lay down some sort of mesh that would stop weeds from growing up through the mulch. After more thought, I decided I wanted to use some sort of brick instead of edging (the edging would have to be dug deeper into the sod, again hurting the surface roots), piled the mulch bags in the garage, and made a shopping list for pavers and mesh for the next trip to Menards.

And so the problem sat for the last two months. (Yard work is not how I care to spend my spare time.) This morning, the lawn maintenance crew arrived while I was fetching the paper. I saw an opportunity and decided to solve the problem another way:

I asked them not to hit the tree with their whipper.

Annals of Homeowner Stupidity (DIY Remodeler Division)

I bought the house I'm living in now last February; nice "rambler" (ranch)-style place, one owner since it was built in the '50s, one block from a decent 24-hour grocery store. All in all, pretty content.

Except for the kitchen, which apparently was remodeled by the children of the original homeowners when they inherited it and prepared it for sale. The original 1974 electric range, reset in the cheapest formica you can find; an exhaust hood so low that steam condenses on it and drips back down into the food; the heating register face-up on the floor right next to the cooktop; the fluorescent tube lights set into a drop ceiling. Gah.

At any rate, Tuesday morning I notice water dripping into the window. Outside, it's clear that there's a huge ice dam built up at an northwest-facing inside corner of the roof, with water running under the soffit and down the side of the house behind the aluminum siding (and don't get me started on that bit of stupidity). I go up in the crawlspace, and other than a small pile of snow on the insulation under one of the mushroom aerators, the insulation doesn't look completely useless.

First step: keep the water from soaking the window, and dripping into the sink. Solution: Funnel duck[1]-taped to the shade, drain hose attached, see illustration below.

Consulting with my friend Lester, who knows his way around building insulation, the clear indication is interior heat reaching the roof, causing melt, hence problem. Clued in, I remove the drop ceiling in the kitchen and poke my head up.

The blessed dears[2] had cut away fifteen inches of ceiling from the outside wall into the room, for a length of about ten feet. They cut the top four inches of the inside wall out, exposing both the wall studs and ceiling joists. Then they put in a six inch drop ceiling to mask their sin. Can't see it in the photo, but there's daylight visible to the right of that inset light fixture.

So: one pair of hedge shears, one roll 6.5in R19 unfaced batt insulation, and a half hour measuring, cutting, piecing together, and trying to get the drop ceiling tiles back into place. Hope this is the major cause, and the dripping will stop; it's 36F outside right now, so I won't know for a while. Even if that fixes it, I'll still probably have to pay somebody to steam off the hundreds of pounds of ice next spring, so it doesn't all melt back into the house.

Next summer, if my Tucson and St. Paul houses ever sell, maybe I'll be able to replace the kitchen with something in which one could actually use a funnel for its intended purpose in cooking, rather than to divert leaks.

[1] Not, in fact, "duct" as I had thought for years. That's another post.

[2] This is what's called a "euphemism". The actual term used, elided out of respect for the sensitive, was more pithy, though not particularly original.

dehumidifiers and blatent ignorance

The basement's a bit damp even when the downspout works and the water doesn't seep in through the walls and flood the floor. And a friend tweeted a reference to an article about dehumidifiers. So I start browsing.

One of the things I find is this article, which includes:
... since we're setting it up to drain automatically we can buy the smallest one they make. The pint size is only relation to the capacity of the tank and has no bearing on the compressor size. They're all the same. So at least we saved money buy getting a smaller one this time (30 pint).
Oh, for *#@'s sake.  Is it something about the web that encourages people to make categorical pronouncements that are demonstrably wrong, or does the web just allow people to expose their ignorance to a wider audience?  The "pint size" is a dehumidification capability measure indicating the number of pints extractable by the unit in a 24 hour period.  It's related to the reservoir capacity only in that something that sucks out 70 pints in a 24 hour period probably should hold more than a quart.  See this, and download the Energy Star spreadsheet from that site to compare the efficiencies of different models and manufacturers: .  Look at the Lowe's web page to verify that the 50 and 70 pint/24h models from Frigidaire both have a 17 gallon (136 pint) reservoir.

Assume she needs to remove 20 pints (9.5 liters) per day, about right for a "wet" basement of 1000 square feet (see the calculator).  Her model does 1.4 L/kWh; there's a 45 p/d model of the same humidifier that does 1.8 L/kWh, which would save 1.5 kWh/day or about $4.60 per month.  Could be as much as $55 per year.  For my case (12.3 L/day, 8 months per year), the 70 p/d Frigidaire model would pay for the $96 price difference from the 25p/d model in less than 14 months.

This sort of thing makes "expert" an expletive.  At least it irritated me enough to learn something, though the value of the time I spent is probably nearly the value of the cost savings the knowledge enables.

poem

So I wake at 530am on the first day of a business trip with a poem (of all things) half-formed in my head and screaming to be written down.  Huh.  Well, it's here.  Might as well deal with it.
The sun won't look at you any more.
She buries her head in the fluffy white clouds
and all the cheerful calls of the birds
and industrious buzzing of the insects
will not draw her forth.

I envy her resolve.

Cost/benefit analysis: contracting lawn services

Shelley asks:
So what's their hourly rate? Nine minutes is an awfully small divisor.
Fair question.

Nine minutes to do the yard.  This is probably a best case; it was the end of the day and they undoubtedly wanted to get home.  You need to assume travel time as part of the cost; if the customers are closely located, it's reasonable to estimate that doing my yard added fifteen minutes to their task list.  They do it weekly, so let's say one hour per month.  They charge $175 per month; that includes special cleanup during spring and fall, which certainly takes longer.  Still, with two people, let's say it's about $85 per hour.

As long as we're analyzing:  By invoking the Google we can conclude that a standard residential mower has a swath of about 21".  Commercial ones that seem to be about the size I saw through my window are about 52".  Given overlap, it'd take me three passes for every one they took.  Furthermore, even if I bought a mower that diverted power to its wheels, I'd still take a lot longer to traverse the yard once: the guy really flew.  So say I'd be pushing (2-3mph) at a quarter the speed he was driving (8-12mph).  Round down to be conservative, and in combination of the width and length figure it'd take me ten times as long to cover the same ground.

So: 1.5h per mow.  Add a half hour for trimming the borders and scraping the impacted grass off the mower for storage.  4 mows per month says 8 hours per month, absolute minimum.  My time is worth more than than the $23 per hour plus hayfever I'd get by doing it myself.

Plus, they actually do the job; I'd put it off as long as I could, be grumpy when I knew it needed doing but didn't want to, and resentful when I finally forced myself to do it.

Seems like a deal to me.

The power of professionals

The house I now live in in Roseville is on a quarter-acre lot (0.26 acres, according to the flyer).  The house itself has a footprint of about 1300 square feet, and there's no garden, so there's an awful lot of grass.  I tend to allergies and hayfever, so the thought of mowing that just sent shivers up my spine.  I contracted it out to a company called "Worry Free", who helped me last year with shoveling the snow at my previous house (another task I'm not thrilled about, but in this case really couldn't do since I was gone 3 out of 4 weeks).

The other houses in the neighborhood have similar sized lots, and I see the poor bastards out there on the weekends.  The renter to the east, toiling away.  The husband to the west, same.  Both pushing their nice gas-powered mowers with about an 18" swath, back and forth, forth and back, for the better part of an hour.  Imagine doing this thirty years ago with a manual rotary mower.  Life these days is better, but still: No.

My guys?  Nine minutes.  Timed it.  Pickup pulls up with the trailer.  Guy 1 gets out, grabs the weed whacker, and takes off toward the fence and the shrubbery, trimming.  Guy 2 pulls down the back gate, disappears inside, there's a roaring noise, and out he shoots on a self-propelled mower with a good 4-foot diameter swath, him standing on a little two-wheeled platform that drags behind.  Thing's gotta do ten miles an hour on the straightaways.  Turns on a dime; reverses same.  Three minutes in the front; just under five in the back.  Back and forth, forth and back, out the side gate to the street and up the ramp.  Pull down the trailer door and off they go.

Nine minutes.

Awesome.

good grief

Quote's too long for a tweet, but just can't be left to pass without comment:

From this article:
8. Do something simple to surprise people. At the d.school, they painted the women's restroom lipstick pink, and hung disco balls. "That makes people realize that somebody cares about your experience," Kembel says.
Actually, never mind the comment.  There's nothing to say in response to that.

twiblog

I said I wouldn't touch Facebook again for a while, but as long as I'm wasting a perfectly good Sunday morning sitting at the computer instead of making cornmeal blueberry pancakes (sorry, Shelley, not that into bananas):

For getting notices of new blog posts tweeted, the instructions are here.  Do they work?  We'll see.

A limited application of the other direction would also be nice---viz., a button that points to my twitter feed (not auto-posting tweets, which is just (a) wrong, (b) pathetic giving how rarely I twit, and (c) a complete conflation of conceptually different media). There's probably a gadget that can be added.

But no: for now, baby steps. Especially since I seem to have obtained my first unknown follower on twitter.  In the words of Morris Day, "Hello; do I know you?"

in my face...

Fine. I give up. Facebook rules the world. What the heck. I'll sign up.

I've followed the Sophos recommendations on security settings, which took quite a while to wade through.  If Google's mantra is "Do no evil", I think Facebook's is "G'head, it's just a little apple".

It's a actually a little scary, seeing the "Who you might know" list.  A couple (recently) former co-workers: ok.  A close friend or two: fine.  A woman I went on a couple dates with: weird.  But a guy who worked for one of our subcontractors off and on a year or two ago?  Somebody who, if he's the Murray I think he is, came down from Phoenix twice to play with a Taiko drum group I was in four years ago?  WTF?

I think those privacy settings are Good Thing (tm).  And that this is enough Facebook adventuresomeness for a while; let's just let it lie fallow and see what sprouts.

Lessons on Human Error, Re-learned Once Again

On a recent trip I had an experience showing the foolishness of trusting in human rationality.  After checking in to my hotel, I got to my room, and could not unlock the door.  It was the usual insert-magnetic-card lock, but when I did so either nothing happened, or it clicked quietly and a little red LED flashed.

I determined there were two possible answers: first, the card was bad; and second, the battery in the door reader was weak.  I returned to the desk, got new cards, and tried again.  Same failure mode with both cards.  While I was standing there despondently inserting the cards one after another, hoping things would change and I wouldn't have to trudge back downstairs and ask for another room, a hotel maintenance man came by, asked what the problem was, took one of the cards, and immediately opened the door.

What had happened?  As an external observer, you can probably guess, but I'll tell it in order, so you can see where things went wrong.

First, I had trouble locating the motel. It's on the northwest corner of an intersection, and I didn't know what it looked like.  I followed the GPS woman's advice to turn onto the side street, but saw nothing that resembled a Motel 6.  I looped around the blook and approached from the other direction, at which point I could see the sign and the driveway (which was invisible and inaccessible from the side street).  This left me disgruntled.

Second, on arriving I was miffed to notice that I would have to pay extra for internet access during my stay.  Another negative, in this case attributed to the hotel itself.

Third, when juggling my luggage at the front desk, I put the keycard in my shirt pocket with my phone, remembering only as I approached the door a rumor that the docking hardware on the Motorola Droid could affect magnetic card strips.

At this point, I was pre-disposed to think poorly of the motel, and had reason to believe the card I'd been given wouldn't work.  That it didn't simply confirmed my predisposition.  When I went back, the desk manager reprogrammed my card, and gave me a second "just in case", strengthening my hypothesis that the cards were likely to be faulty.

I blame the fourth contributing factor most of all.  Here is a photo of the front and back of the card:

 


As you can see, the most important piece of information the card has to convey is that Domino's is the recommended local restaurant, and its number  is helpfully provided in large type.  Now, when holding such a card up in front of you to read it, you would naturally place your thumb on the white part, just below the number.  When inserting it into the reader, you'll keep holding it that way.

Unless you want the door to open.  Then, apparently, you are to understand that the two-millimeter triangles on either side of the fine print (which warns of minimum pizza purchase requirements and that the drivers carry little cash) are not merely decoration, but are intended to tell you the direction in which the card is to be inserted.

The maintenance man, being familiar with the cards, immediately opened the door.  I had formed a hypothesis, and the outcomes of my experiments were consistent with that hypothesis, so I stuck with it.  The possibility of trying a different experiment, like turning the card around, didn't even occur to me.

Review: Rationality is strongly influenced by mood.  People, having formed an  opinion, will tend to see the evidence that supports it.  In the absence of inconsistent evidence, people will rarely actively search for an alternative  interpretation that contradicts their beliefs.  And input from an external party can disrupt the bad perspective, leading to better understanding.

None of this is news.  See, for example, James Reason, Human Error.  Relevance?

Well, it has clear relevance to most activities related to design and implementation of complex systems.  In particular, I have a new task to ensure high reliability in software used in a wireless sensor and control network.  What my experience has suggested is that, at a minimum, code reviews should be required for all changes that will go into a release of this software.

The process support for how we go about doing that is another essay.

droid for now

The droid does not support streaming video in the browser.  Pretty much at all, though nobody actually says so: there's all kinds of noise about how to convert your videos so you can play them from the SD card, and people answering questions that weren't asked, but based on the 83'd bug against Android (I filed number 5756 this morning) it just can't be done.  Not much help when you want to be able to watch a live feed from a security camera, or stream a motion capture clip.

Of course, the pr0n folks have it figured out, but since there are no quality open source Real Time Streaming Protocol servers available--and even if there were I don't want to install, configure, and harden one--that's not really an option open to me.

In order to do what I really want with this thing, somebody needs to
  • Support streaming video in the standard browser
  • Support client certificates across all apps (at least browser and email)
  • Get an IMAP client that has a reasonable interface to a hierarchy of folders
All the other stuff (adding root certificate authorities, getting OpenVPN into my network)---that I can handle, but these are a bit much for a weekend project.

Oh, and will somebody please tell Google that in this world of distributed collaboration a calendar that doesn't associate a time zone with an event is just stupid?  Another story....

So the priority of getting the OpenVPN connection working dropped a little bit, and it's time to go back to CC430 tool chain support.

Friday, January 1, 2010

ah, technology....

So, Wednesday I got a Motorola Droid.  The theory being that, now that I'm working on things remotely connected to social networking, I should have a personal communications device capable of interacting with the Internet, whether that be web, Twitter, or whatever.  And this thing has a screen with enough resolution that it's actually pretty amazing.

And the main things I really wanted to do were get access to my internal web and mail servers.  Normally, this is done with OpenVPN, but an alternative would be to use client and server PKI certificates, which I'm also set up to handle.

How much has to be done to make the droid deal with this?  Let's see:

The simplest solution would be to load the thing up with client certificates and open my firewall using certificate-based authentication.  Can't be done.  First, I'm using a self-signed root certificate, and there's no facility to add a trusted one.   Solution?  Jailbreak the phone, get root, and update the cacerts.bks file.  Fortunately, they used the default password on the file, so I could do that.

Great, now the browser trusts my servers, but to ensure security now that I've opened my firewall up, I want the servers to authenticate the clients.  The Droid's browser and email infrastructure apparently won't send client certificates when servers request them.  I'm not sure what its certificate store actually does, then, because I *think* I successfully got one installed.  Something to look into, but for now certificate-based browser is DOA.

Next thing is to let the device connect to my networks through a VPN.  The Droid supports a couple VPN alternatives, which appear to be Microsoft-based.   OpenVPN isn't one of them, and that's what I'm configured to use.   So: Do I rebuild my firewalls with a non-OpenVPN solution that the Droid maybe will support, or do I try to get OpenVPN to work?

Like hell I'm going to screw with my firewalls.  OpenVPN it is.  Already jailbroke the phone, so now it's a matter of grabbing a copy of the tun kernel module from somebody, OpenVPN from somebody else, a couple apps from Android Marketplace, and go.

So close: got the client on the droid connected to the server on my firewall.  Except I use bridged OpenVPN so all my machines look like they're on the same subnet.  Very convenient, except the droid doesn't have the bridge-utils package, it doesn't look like anybody ever made it, and even if they did this probably wouldn't work since the droid has a PPP connection not an Ethernet one, so there's nothing to bridge to.

So, after having turned off routed support in OpenVPN in my iptables rules and DNS configuration, apparently I'm going to have to put it back.  It'll have to be a separate OpenVPN server, because again I'm not going to screw up the ones that already work in bridged mode.  But in theory it should be possible.

Not tonight, though.

the perils of choice

During dinner with my parents last night, the topic of how people react to "too much" choice came up.  My mom said how she always felt too much choice was indeed too much, and kept her from making any choice, but thought she was unusual and that most people liked to have a lot of choice.  My argument was that people say that, but when you look at what they actually do, too much choice is bad.

Following my general rule of locating authorities for claims I made, I defer to Barry Schwartz, whose excellent Google talk addresses this in wonderful detail.

Some thoughts that come to mind while watching that:

Theory: Younger people, who have grown up in a world that inundates them with choice, have in reaction tended to become satisficers, because the alternative (maximizer) generally leads to unhappiness, for reasons explained by Schwartz.  Consequently, they are happier and more adaptable than those of us whose selection model was developed at a time when maximization was the preferred approach.  (In a situation with limited choice maximization, which is naively the preferred solution, is likely to be indistinguishable from satisfaction because the same choice meets both criteria while the few remaining alternatives don't even satisfy.)

Perfection is the enemy of good enough.  But "good enough" is the enemy of "great:".  Maximizers want "great".

Leakage: The experience of the context of a decision impacts the experience of the consequence of the decision.  Specifically, if you are stressed while making a selection, that stress remains after the selection is complete and you are moving on.  Consequently, you will be less happy with the results, and less likely to put yourself in a situation where you must make similar decisions.

Successful continuous bloggers, then, are those who do not spend hours agonizing over word selection and searching for the perfect phrase, because the people who do so are dissatisfied with the results---especially in the absence of external validation that would increase the return on their investment---and consequently their postings fall off and the blog is abandoned.

ah, snow....

We got about five inches of snow last night here, and I had to do shopping today or I'd be serving frozen waffles to my parents for Christmas dinner.  Store parking lots on Christmas Eve with snow.  Yuck.

In fact, it was pretty benign.  I had the foresight to get a Subaru Outback when selecting my car here: all wheel drive, eight inch clearance.  A little slippery, but no problems getting out and about, even in the side streets which St. Paul, in its infinite wisdom, decided didn't need to be plowed.  (They have belatedly declared a snow emergency now, which appears to mean that they're going to sit on their collective behinds until 9pm tonight, at which point they'll start plowing the five inches that accumulated yesterday, plus the 2-4 inches coming today and the 5-9 inches tonight.  Just across Hamline in Falcon Heights, all the streets including the side ones were plowed sometime before 8:30a this morning.)

The parking lot at the co-op, and in fact all the other stores, was well plowed and barely a third full.  I95 a little slow, but not congested.  University Avenue a total sloppy mess (St. Paul, again; Minneapolis plowed their stretch), but very few vehicles daring it.  The curb in front of Penzey's on Grand (St. Paul: wait for it...) actually had a cleared spot with room for two small cars---and a Jeep Cherokee Limited slapped in the middle of it.  But the Subaru easily drove over and out of the pile of snow left in the remaining spot.

By about 1030a, I was wrapping things up, and everybody else seemed to be getting to the point where panic had set in and they just had to venture out to buy that last wind-up parrot for Cousin Joe's rug-rats even if it meant trying to navigate their Ford Festivas through the drifts.

I love my car.  And...

Go SPUGs!

On the limits of the right to opinion

On a recent trip, I stopped at a news kiosk prior to boarding the plane and got a copy of the 24 November Wall Street Journal.  This was really so I could get change for the taxi at my destination, but I also tend to like the articles.

Apparently, though, I don't care for the editorials.  This was the issue that claimed to "reveal an effort to hide the truth about climate science".  The short of it is excerpts from email archives of certain scientists at the University of East Anglia's Climate Research Unit, which include statements about researchers' efforts to block release of data under FOIA-type requests.  Since I happen to believe in the theory of anthropogenic climate change, and the editorial clearly shows the WSJ's position that global warming is bunkum, this rubbed me the wrong way.

I'm not going to support any attempt to hide raw research data.  But I do sympathize with the frustrations of somebody who is asked to release it to people whose qualifications to judge it are dubious and who will inaccurately present a selected view of it in a popular forum in such a way that sound conclusions are made to appear ludicrous or unsupported.  Ad hominem attacks and nay-saying is easy; science, properly done, is harder.

One of the fundamental problems I have with the whole global warming controversy is the number of people who make unqualified assertions based on applying their own common sense to issues that are, in fact, far more complex than they have taken the time to understand.  Take as an example (paraphrased, see original):
The claim that melting icebergs raise sea level is garbage.  My icewater doesn't overflow the glass when the ice melts.  Water expands as it freezes, and the amount of water displaced by an iceberg is equal to its weight.  So if the iceberg melts, the water level won't change at all.

On the surface, a compelling argument.  It appeals to common daily experience, so everybody feels they can judge its validity.  It references Archimedian principles of displacement, so has the air of authority.  When I read it, I thought "good point".  Unfortunately, with a little more research the argument is both specious and invalid.

It's invalid because it considers only the primary effect.  True: If an iceberg melts, the water it returns will not result in an increase in water volume.  However, if the iceberg melts, it presumably has done so because the temperature of the water has increased.  And thermal expansion means that the volume of the water will increase as well.  Sea rise.

It's specious because, regardless of whether the cited claim was represented properly (I didn't read the original paper to find out), the real argument is not that melting icebergs will raise sea levels, but that melting continental ice sheets will.  It's all that water currently above ground in Antarctica and Greenland that will provide us with beachfront property in Arizona if the temperature rises too much.

And that's a trivial example.  Get into three dimensional fluid dynamics simulations, advanced statistics, and chronological reconstruction from chemical analysis of ice cores and I'm not even going to try to make the effort that would be required to qualify me to judge detailed arguments made from first principles.

What I can, will, and have done, though, is read about those papers, and form my opinion based on the most compelling and best referenced analysis.  My belief in "global warming" is founded from reading pieces of the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change.  Not editorials in a national fish-wrap.  Not testimony from people of dubious qualification before politically-charged House or Senate panels.  Not blogs.  The Summary for Policy Makers and pieces of the summaries of two of the three working groups.

For due diligence, I tracked down the best rebuttal I could find of AR4, and read that.   Where AR4 presented positive arguments and falsifiable theories, the ISPM nit-picked.  Where AR4 listed hundreds of active researchers in climate science, ISPM had less than a dozen.  It just wasn't compelling.

So: Everybody has a right to their own opinion?  No.  You may have a right to an informed opinion.  Even then, there may be limits on that right depending on the depth of your information and the impact of your opinion, but that's a subject for another essay.

I believe that human activity has caused environmental changes that, if unchecked, will have significant negative impacts.  Some parts of the world may not be affected as much as others.  External events may ameliorate the effects in the short or even long term.  But on the whole, if things go as it appears they will, it's going to be our grandchildren who will have to pay for our self-imposed ignorance.

My opinion.  If somebody actually reads this thing and has further information I should consider, I'll take a look.  But it better have more behind it than anything I've seen so far.

frist!

Samuel Pepys I'm not, but something must be done to inaugerate this thing. So, I offer a simple dessert: about a quarter cup of frozen wild blueberries, allowed to thaw in a small bowl; pour in maple yogurt to taste; sprinkle with candied ginger. Very nice.
