Morning Walk, with Random Thoughts...

As usual, this morning at around 3 am, the dogs and I gathered near the door for their morning walk.  The last few days, though, have been very confusing for the dogs.  You see, last weekend we replaced the patio door through which we begin our walk.  The old door was a sliding door, sliding from right-to-left, and we walked out the right-hand side of it.  Some of our dogs have been doing this every morning for over 12 years.

The new door, however, opens from the middle, left-to-right, and we walk out of it near the center.  This morning (like the previous few mornings), the dogs gathered near the right-hand side of the door, waiting impatiently for me to affix their leashes.  When I had them all hooked up, and opened the door – the confusion began.  You could almost hear them saying “WTF?”, complete with confused faces, as the door swung toward them.  “This never used to happen!”  Eventually we got it sorted out, and left on our walk...

Three things were much on my mind this morning...

The Supreme Court's decision on ObamaCare is the topper – those few men and women are about to decide something (well, let their decision be known) that has a huge impact on my country and on me personally.  A thought I read from Dave Carter expresses it just about perfectly:
“The very idea that we sit on the edge of our seats, eyes toward Washington DC, waiting on the deliberations and dispositions of nine mortals to tell us how much of our liberty we get to retain is preposterous.”
Yup, that's it, Dave.  And yet...here I am, on the edge of my seat.  And I have utterly no idea how they will rule.  Just a couple hours from the time I write these words, we'll all find out...

Jerry Brown just signed California's (yet again) insane budget, replete with all the usual gimmicks he forswore – and with a new one that tops all the previous gimmicks.  This budget assumes that the compliant sheeple of California will approve a massive tax hike in the November election.  Now the Democratic propaganda engine will swing into action, proclaiming to the sheeple that the sky will fall (and damn soon!) if we don't approve these taxes.  The dollars available to pay for this propaganda are awesome in their quantity, as every single organization that depends on public funding is, of course, wildly enthusiastic about these new taxes.  The teachers, public employees, police, fire, prison guards, and all the other vast army of state employees are represented by unions – and these unions have collected (not necessarily with the consent of their members!) vast hoards of cash to pay for this propaganda.  I am afraid the chances for passage of these tax hikes are reasonably good.  We may be headed down the same spiral that Greece is in the thrall of...

And then there's Fast and Furious, which infuriates me – both the program itself, and the subsequent cover-up of it.  Given the invocation of executive privilege, I'm finding it more and more plausible that not only did the knowledge of Fast and Furious extend to the White House (including Obama himself), but that it might have been ordered from there.  The partisan reaction to it no longer surprises me, but it certainly dismays me to see that because they are Democrats (or because they are black, or both) duly elected Representatives and Senators are refusing to hold Holder in contempt – when he so clearly is in contempt of Congress' request for information (which is itself equally clearly within their purview).  There are precious few Democrats who have committed to voting for the contempt motion later today.  For some reason this partisan reaction is even more depressing to me than the rest of the Fast and Furious mess...

But despite all these less-than-happy thoughts running around in my head, the walk was as beautiful as ever.  The Milky Way glowed overhead, and the dogs were, as always, full of delight and joy.  Cool breezes intermittently puffed down the hill above us, carrying with them the wonderful smells of the chaparral.  The morning was quiet and peaceful, and the dogs and I felt like we owned it completely...

Senior Moments...

This song is dedicated to my parents:

How Our Vision Really Works...

An excellent explication of the way our perception of color actually works, including both the physiology and our brain's influence.  The explanation is very accessible – you don't have to be a scientist to understand it.  What you were taught was almost certainly very different...

A Visual Git Reference...

If, like me, you're new to the world of git – you might find this visual reference quite useful...

Two Words...

James Taranto has two words for you.  Listen up!

This Means Something...

...though I'm not entirely sure exactly what.  Part of it, to be sure, is the ongoing triumph of style over substance.  But I think it goes deeper than that.

One thing I feel sure of: this is not a good omen for our species' future...

Greece Showed the Way...

...and California said “Yeah, that's what I want to do!”

When does the madness stop?  California seems hell-bent on destroying it's attractiveness on every front: as a place to live, a place to do business, and even as a place to visit.

It's close to being time to leave...as so many already have...

Both True and False...

If you're a programmer, you probably think of a boolean variable as having one of exactly two distinct states: “true” and “false”.  The value of that variable is either true or false.  It can't possibly be both.

Oh, yes it can!

Well, in “C”, at least, and probably in other languages that are relatively close to machine language.

Which got me to thinking...  The rise of languages like Java, JavaScript, and C# – all of which nearly completely abstract the underlying computing machinery away – is an enabler of the current programming world in which developers can be quite successful without ever understanding how computers actually work.  With languages like “C” (or assembly language), that just isn't so...

I'd Blow It All On You...

The Curiosity Challenge...

On August 5th of this year, at 10:31 PDT, the Curiosity Rover is scheduled to plop down onto the surface of Mars.  It is by far the most advanced probe anybody has ever attempted to land on any planet, and (assuming it lands successfully) we expect it to produce great science data at least through its primary mission.

Curiosity is also the biggest and heaviest probe anyone has ever attempted to land on Mars, and this meant some tough engineering problems to solve.  The engineering solution involves an advanced ablative heat shield, the largest supersonic parachute ever designed, a rocket-powered sky crane, high resolution descent radar, and a completely autonomous computer-controlled landing system.  Every bit of this has to work perfectly, or the Curiosity landing will fail (as so many previous Mars landings have failed).  For those of us who, like me, are more excited about robotic probes like Curiosity than we are of the manned space program, this landing is real edge-of-the-chair stuff.  It's also a spectacular feat of engineering in its own right, completely aside from the rover itself.

The video below is a sort of mini-documentary, very nicely done, about the technology developed to set Curiosity down on the surface of Mars...


Takedown!

Ann Althouse (one of my favorite bloggers) does a spectacular takedown of Jonathan Turley's proposal to pack the Supreme Court (a la FDR).  It's a thing of beauty, her takedown – one imagines Turley's ego lying shredded on the floor...

The Care and Feeding of Software Engineers...

Lots of truthiness in here...

Political Jokes...

Here's a big collection of contemporary political jokes, mostly about either Obama or Romney.  Some of these are as likely to make me cry as laugh.  The most interesting thing to me – Obama is getting the same treatment as Romney from the humorists.  No more “hands-off” attitude.  I guess there's just too much comedic gold for them there...

Sikorsky Prize Within Reach?

Watch the human powered helicopter below stay aloft for 50 seconds.  Awesome!  The Sikorsky Prize ($250,000) has remained unwon for 30 years.  One of the three requirements is staying aloft for 60 seconds or more.  They're getting very close on that front!  Another requirement is reaching 3 meters (almost 10 feet) high; they've got a ways to go on that...


Citizenship...

Scott Adams (of Dilbert fame) has some thoughts on how one becomes a citizen of any particular country.  He doesn't really propose any solutions, but makes some unusual observations and a few predictions.  I found myself agreeing with many of his observations, in particular the arbitrary and capricious nature of “place of birth” as the determinant...

Optical Illusions...

It's a great one below, and there's another where that one came from.  I love illusions like this one that demonstrate so clearly the major role our brains have in visual perception...


MRI of a Human Birth...

This is the first ever MRI “movie” of a human birth.  It's just 25 seconds long, and is comprised (really) of a series of still images from the MRI, all strung together to make a movie.  There's much more about this here.

Interesting article from NPR (though they've spelled “statolith” incorrectly on their drawing!) and a more detailed explanation...
