Watch the Solstice Approach (and Recede)

As an equinox or a solstice (in this case) approaches, my year clock starts indicating the time of the event with increasing precision, using indicator arrows like the one shown below (each equinox and solstice has a unique arrow; this one is for the winter solstice).


While such arrows are visible year-round in the clock’s year ring, as the month of the event is entered an arrow appears at the

Check Your Drug Interactions, Avoid Rude Surprises

I recently found myself in a situation in which an over-the-counter pain medication prescribed by one of my doctors began to poison me, and, given enough time, probably would have done permanent damage to some major organs I've come to depend on over the years. I didn't realize what was happening at the time, I just lost feeling in a section of one hand, as the pains that were supposed to be

Wolfram|Alpha: How it Came to Be, What it Does, How it’s Done, How it Grows

I’ve been sending this link to people for a year or more. I think I’m overdue to make it available to everyone:Making the World’s Data ComputablePersonally, I found it fascinating and illuminating after being left clueless about what Alpha was by the industry press.Need some specific examples to understand how to use Alpha?

Maintaining In-House Technical Skills

From Project Apollo: The Tough Decisions by Robert C. Seamans, Jr., pg. 84:When conducting advanced technical efforts, it’s imperative to maintain in-house technical skills of a high order. But high-grade technical personnel cannot be stockpiled. They must be given real rabbits to chase or they will lose their cutting edge and eventually seek other employment.

The “Glass Teletype”

From TOG on Interface by Bruce “TOG” Tognazzini, pg. 131:Early computers used printers as their sole output. When programmers at various large traditional computer companies were first given monitors, they immediately duplicated the printer interface on their green, glowing screens, giving rise to the term “glass Teletype.” With this lavish investment of more than 20 minutes of design time behind

The Intuitive Person vs. Western Education

From TOG on Interface by Bruce “TOG” Tognazzini, pg. 103:Western education is heavily biased toward intellect over intuition: Intuition is endowed with a perverse habit of delivering results most slowly when the need for speed is greatest. [....] Telling a bunch of kids to “think about it for a couple of hours, a day, a week—whatever it takes—then get back to me” just doesn't fit into our

Goldilocks

From TOG on Interface by Bruce “TOG” Tognazzini, pg. 91:For those not well-versed in English folk story tradition, “The Three Bears” is the story of a young juvenile delinquent who breaks into a neighbor’s house, vandalizes it, and manages to kill herself while trying to escape. Good parents read it to their children, instead of letting them watch all that violence on television.

The Cost of Imperial America

From War Is A Lie by David Swanson, pp. 284-285:

We are [...] proud, however, of shoveling huge piles of cash through the government and into the military industrial complex. And that is the most glaring difference between us and Europe. But this reflects more of a difference between our governments than between our peoples. Americans, in polls and surveys, would prefer to move much of our money

The Syntax of Photography

From The Keepers of Light by William Crawford, pp. 6-7.[....] Are there "syntactical" rules of structure for the way we turn objects into photographs, rules that compel the infinite possibilities to fall along a finite line, just as there are rules for the way we turn concepts into statements? How you answer this question tends to determine how you approach the study of the history of

Consultants

What’s great about hiring consultants is supposed to be that your organization has no committment to them. What isn’t much mentioned is that, by the same token, consultants have no committment to your organization.

The Measurement of Misfortunes Revisited

A few days after posting Mark Twain and the Measurement of Misfortunes, I realized something obvious that I’d overlooked for years: The bad habit of seeking an external yardstick by which to measure, compare and disregard human pain and suffering—well examined by Twain in that quoted material—is the basis for a reductio ad absurdum.

The reduction is straightforward: If the pain or suffering of

Mark Twain and the Measurement of Misfortunes

Ever since reading Mark Twain’s autobiography years ago, I have, with some regularity, found myself presented with situations that brought the following passage to mind. Another such situation arose recently, and caused me to search out the passage, as my memory had stored the lesson well enough, but had come up lacking in the matter of retaining the story sufficiently to pass it along properly

All Branchers (and Owlets) Safe and Sound

All three branchers were sighted at the same time in the same tree (the tree in which I deposited owlet/brancher no. 5 after it left the nest on the 8th). The brancher that appeared largest had its own perch, while the other two (presumably owlets 1 and 2, who left the nest together on the 10th) were perched together on another limb. Those two had to cross perhaps 75 feet of "open" space (the

Owlet Family Portrait and No. 5 Grows Up

I brought down the nest box late this afternoon to install the owlet rail. Fortunately, as I was in the process of assessing what pieces of its mount I'd have to replace, I discovered that (once again) I'd made a spare. So, the only part I actually had to replace was the branch that forms the rail. The old one would probably have been fine, but I tripped over it while owlet herding, and the rest,

Owlets Four and Five on the 21st

Since acquiring owlet no. 4 for medical treatment, Sallie, my raptor rehabber friend, has acquired two more young screech owls, which she refers to as “screechlets” to distinguish them from the three great horned owlets, and four barn owlets she was also caring for on the night of the 21st when these photos were taken. One of the screechlets, now designated owlet no. 5, is young enough to fit in

The Owlets on the 17th

As people following my notes on the screech owl cam’ page will be aware, on the 17th I brought down the nest box mid-afternoon in order to remove a worrisome build-up of what appeared to be fire ants (the small, vicious, invasive species we have here in central Texas; not the big, relatively relaxed natives that live further north in Texas). Needless to say, I took the opportunity to photograph

Today’s Chickens; Yesteryear’s Goats

Observed on my street today: A pair of chickens browsing someone’s front lawn. Not the sort of thing I see everyday. Or ever.

However, there was a Christmas day around ten years ago when I looked out of my front window and saw someone leading a herd of goats down the street. I’ve checked on subsequent Christmas days and not seen a single goat, which has been disappointing. I wouldn’t like to

Fourth Egg Laid

The fourth egg has been laid, but, due to the exceptionally poor reliability of the video capture system lately, I wasn’t able to get a picture of it. With luck, the video capture system will stay up for a while, and Mme. Owl will reveal the eggs again soon.

A Better Look at All Three Eggs

With Mme. Owl out for a bit of hunting, a good look at all three eggs was available this morning. Next step: Reviewing the image archives to try to determine more specifically when they were laid.

Egg no. 3 Arrives Early?

Noticed just now: Egg no. 3 has arrived. Unless my memory is going, the interval between the laying of each egg in a clutch is supposed to increase over time, but I don’t think that has happened in this case. I’ll have to review frames from the nest box this weekend to try to narrow-down the time at which each egg appeared, but I think the delay between eggs no. 2 and 3 was either the same, or a

Egg no. 2 Appears

Egg no. 2 was laid sometime this afternoon, probably between 1 and 5:50 PM. Right now, I can’t narrow down the time better than that.

The time between eggs will increase with each egg, so some patience will be required before we know the size of this clutch. As always, stay tuned.

Egg no. 1 Debuts

Well, I’m going to have to start updating the nest box cam’ site properly, now; Mme. Owl has laid her first egg. And the viewers get the credit for this find. I thought that I was watching the owl cam’ as I worked frantically into the wee hours on a major project at work, but I failed to notice in between all of the work that my web browser had stopped updating the page hours before. There was

Mme. Owl Spending Her 2nd Day in Nest Box

Mme. Owl spent all of yesterday in the nest box, which suggests that the appearance of the first egg is very near. She’s now begun spending her second consecutive day in the nest box, which suggests that that bit in the first sentence about “the first egg is very near” is correct. You can see for yourselves on the owl cam’, assuming it isn’t de-railed by one of the technical issues I’m trying to

Mme. Owl May be Spending Her First Day in the Nest

Mme. Owl may be spending her first day in the nest box this year. If so, things are moving along a bit faster than I expected. The first egg, if memory serves, may appear within two days.

Mme. Owl in the nest box this morning, amid debris deposited there by a pair of starlings. So far this year, she hasn’t remained in the nest box for more than about 10 minutes at a time (although the number and

Owl, meet Owl Box; Owl Box, meet Owl

I haven’t brought-up my eastern screech owl nest box cam’ for the year, because nesting isn’t underway, but I’ve been running the image capture software anyway, trying to confirm my suspicion that my local owls are actually preparing to nest in my box. And, as you can see, I now have confirmation.
That’s the female owl shoving around the bedding material to create a depression to hold her eggs at

The Screech Owl Nest Box: A Depression Sets In

My ability to sleep and my sleep patterns are in ruins, my local medical community notwithstanding. As an example, I just got back from 16 hours at the office. Why a sleep-deprived person can even do that, I don’t know. But for some reason I did, and there went my opportunity to keep an eye on owl TV last night in hopes of seeing a visitor.
Sigh.
Nonetheless, I tuned in as soon as I got home. The

Bee Removal Phase 3: The Box is Back

It took about eleven contiguous hours of work, but my screech owl nest box is back in business, and not as a bee hive.

The nest box had to be disassembled to properly clean all of the bee grunge out of it. That meant breaking it down into its major components: (1) the frame, which includes the back wall visible in the photos, (2) the fold-down front with integrated infrared entryway sensor

Bee Removal Phase 2: The Smell of Honey and Death

Yesterday (Saturday), it was misting heavily when I would like to have begun the nest box cleanup, and, under those circumstances, just handling the plastic covered steel cable that runs through a block and tackle to raise and lower the box would have been a challenge. Also, I’d’ve either had to stifle in a rain suit, or be soaked during the time it would take to get the box down and begin the

Bees Dead. Next Step: Cleanup.

I've just pulled the No-Pest Strip from the entry hole of the screech owl nest box. It was full of dead bees, and there were no signs of live ones, so I think that a little more than two days of exposure to the fumes from the Strip has ensured that the hive is dead. There's no time to begin cleaning-out the box now. That’ll have to start (and, I hope, finish) this weekend. Perhaps, in the

Bee Removal Commences

Well, I couldn’t have put it off any longer without absolutely guaranteeing failure, but I’ve finally begun the process of removing the bees from my screech owl nest box. It’s a very simple, but ugly process: stuff a Hot Shot No-Pest Strip in the entry hole and get away fast. Of course, you have to find a safe way to do that. If you do it in freezing weather, the bees are incapacitated by the

Now Playing on Radio Paradise, My Photos

Radio Paradise, an Internet radio station, that also happens to have been my favorite radio station since a friend (thanks Brendan) introduced me to it many years ago, is now offering a high definition video feed to accompany their music. They’re accepting photos from anyone, provided that the photos meet their admittedly subjective criteria.
I’d been meaning to submit some of my own photos for a

Human Face Recognition, a Presentation by Dr. Shalini Gupta

The Austin Forum, on the evening of January 4, 2011, hosted an interesting presentation by Dr. Shalini Gupta entitled “Digital Human Face Recognition,” which I attended because I find digital face recognition a fascinating technical challenge, an increasingly important social issue, and because I have an interest in a lesser, related problem: automatic face isolation (without regard to identity)

A Dog I Did Know

My family passed along very few stories to me, or, at least, very few that proved memorable. One of them was Grandpa Johnson’s bacon, to which I was not a witness, though I choose to believe it. There’s another story I choose to believe, one to which I must have been a witness, though, to my sorrow, I’ll never, ever remember it. And I kind of hate to share it (it’s my story, and, in that special

A Dog I Don’t Know

I was sure I’d included this story here at some point in the past, but I went looking for it yesterday and couldn’t find it. Therefore, I now pass along the following story from Mark Twain’s autobiography, as edited by Charles Neider, pg. 256:
Doctor John [Brown] was very fond of animals, and particularly of dogs. No one needs to be told this who has read that pathetic and beautiful masterpiece,

How Should the Troops Die?

Alan Grayson, Democratic congressman from Florida’s 8th district, who urged his colleagues to vote against war funding in order to shut down those wars and bring the troops home, was accused by one of his opponents, Kurt Kelly, of putting “our soldiers, and our men and women in the military in harm’s way, and maybe he wants them to die.” Naturally, the accusation was made on Fox News. Here’s the
