Halos in Paradise...

Halos in Paradise...  On our walkie this morning, the dogs and I got so see an especially good “halo effect”, what the Germans call “heiligenschein”.  The photo at right is not mine, but it's very close to what we saw today.  We saw it in the tall orchard grass growing along the road we walked on.

There are (so far as I know) three entirely separate mechanisms contributing to the effect we saw today.  When all three are working at once, the difference in brightness between the “halo” and an area in the sunlight a few degrees away can be as much as 10:1.  Also there can be some pretty color effects.  Here are the mechanisms, from smallest to largest contribution (in terms of halo brightness):
  • Grasses, like most plants, have a mechanism inside them that causes their leaves to tend to aim directly at the sun.  The wind still blows them, and many leaves are oriented such that they can't bend far enough, so this effect is slightly subtle.  Certain kinds of trees (not grass, though) are particularly good at this – especially trees in the north, where sunlight is scarce.  Those grass leaves that manage to point directly at the sun are also pointing directly at your head, where your head's shadow is (as in the photo).  Those leaves will reflect a little more light back toward you than the surrounding leave.
  • Grass leaves are covered with tiny hairs and (sometimes) equally tiny dust particles.  Since we've just had rain, the grass in our case probably didn't have much dust on it.  But those hairs are certainly there.  The ends of those hairs act like little tiny retroreflectors, though not particularly good ones.  This contributes to the halo effect in grass, and even more on plants with hairier leaves (such as Dusty Miller).
  • The grass this morning was covered with raindrops and dewdrops – so much that the dogs were soaked within moments of their first passage through it.  Each of the tiny drops acts as a combination of retroreflector and prism, bouncing the sun's light straight back toward the sun – and breaking it up into colors.  This effect is by far the strongest when there as many droplets as we saw this morning.  It really was quite beautiful...

Progress in Paradise...

Progress in Paradise...  Not much, really.  The wet weather today kept me from working outside, so I had a day of (physical) recovery indoors.  I kept myself busy catching up on all the bills, receipts, etc. that seem to pile up at a breakneck pace.  Debbie's still feeling puny from the cold she's caught, though it looks like she's on the downhill side of it.

We did take an early evening drive out to Porcupine Reservoir.  With the dramatic stormy skies, spots of sunlight, and the lush green of the fields and hills, it was very pretty.  The reservoir's level is distinctly higher; it's now within 24 or 30 inches of spilling over.  Better late than never!  We didn't see any loons, but did see a solitary Sandhill crane, a boatload of mallard pairs, and two terns doing their fancy flying while looking for fish.  Lots of horse and goat babies all along the drive.

I just got back from a walk along the dirt road east of us, with all three dogs.  The rains today brought the worms up, and a platoon of robins was feasting on them.  I'm sure they're all feeding some hungry babies.  This made them bolder than usual; several times we walked up to within about four feet of a robin tussling with an uncooperative worm (not my photo, but the same idea).  In the end, the robin would always decide that risking an encounter with three slavering dogs and a weird human was too high a price to pay for a juicy worm that would momentarily satiate their basically insatiable chick...

Excitement in the cattery...

Excitement in the cattery...  We have a room in our basement that's dedicated to seven of our cats.  The room has five windows to the outside, despite being in the basement.  These are well windows, much as in the photo at right (ours are a bit bigger, though).  These let in more light than I ever would have guessed.  For several hours each day, they also admit bright spots of sunlight for the cats to luxuriate in.

This morning Debbie walked into the cattery to see one of our cats (Kapua, aka “mom kitty” ) very excited about something she saw in one of the north-facing windows: a fledgling robin.  It had either fallen or flown into the well, but couldn't fly straight up to get out of it.  It was a very confused and unhappy little fledgling.

Now if you're not familiar with birds, and especially baby birds, there are a few things you need to know about them.  The first is that to say they're as dumb as a stump is to insult all of stumpdom.  The second is to note that they're incredibly fragile – if you grab them in the normal human way, with your hand, you're almost certainly going to injure them.  They likely won't recover from any such injury.  And, naturally, when they see a great big monster human trying to capture them, they struggle to get away – they think you're going to eat them.  Like Kapua wanted to.

Debbie and I both thought of getting a dish towel to cover the fledgling with.  We know from (hard) past experience that you can turn a bird “off” by covering its head.  But Debbie had the real winning idea: to throw the towel so as to cover the fledgling, while I stayed at some distance.  That worked perfectly: I got it covered on the first throw, then packed it gently into a bubble in the towel, and took it outside – to the vast disappointment of the feline crowd watching the whole affair carefully.

I let the fledgling go at the end of our front door walkway.  It flew away from the house, toward the pines in our front yard, then did an about-face and flew straight back to the house, landing in a planting about one foot from another well window.  Sheesh.  Dumb as a stump would be a welcome upgrade to its brain-power.  As of this writing, the fledgling had not fallen back down into the other well window.  I bet it does, though...

Update: just a few minutes after I first posted this, Debbie called up.  “Bird in the window, again!”  Down I went, dish towel in hand, and repeated the entire exercise.  This time I let it go at some distance from the house, under a blue spruce.  Hopefully it will stay there for a while before diving into a window well again.

Stumps are positively brilliant by comparison!

Progress in Paradise...

Progress in Paradise...  The brush pile is gone!  The whole darned thing is burned up, and only a small pile of char is left.

The stacking that I did yesterday worked a treat – picking it up with the tractor's fork was easy.  I dumped two fork loads onto the ashes of my last burn, and then lit it.  Well, more exactly, I tried to light it.  I used the cardboard from five boxes as “kindling”, but never got a sustainable fire going.  I called Debbie and had her bring me some more cardboard, and after using a total of nine boxes worth of cardboard, I finally got the darned thing going.  The problem was that this bunch of brush was all green wood (as opposed to the dead willow wood I'd burned previously).  With all that water in the wood, I had to heat it for quite a while to boil it all off.  Once I got a sustainable blaze going, though, it burned hot and fast.

Over the next few hours, I dumped load after load of brush onto the same spot, where the fire was burning.  The pile of glowing embers got taller and taller, and ever hotter.  At the peak, I couldn't stand within about 10 feet of the fire – it was just too hot.  After a total of 22 fork loads, I had it all on the pile.  Then I just had to wait for a couple hours while all those glowing embers burned off.  I kept stirring the pile with my tractor's fork (that's a very handy tool, that pallet fork!) to keep oxygen flowing to it.  Finally when it was down far enough I wet it all down until it stopped steaming.  Done with the brush!

As I worked today, locals who knew me honked and waved as they drove by.  My burn pile was just 30 feet or so off the road, so I was in view almost all day.  Two people stopped to see if I needed help (I didn't), and one of those sent their kid back with a mason jar full of ice water for me.  That sure tasted good!  A neighbor pulled over in her car and shouted to me that I was doing a good job.  I think she's really happy to see all the dead wood taken down and burned off.

Now the only remaining work after the Mormon horde's service project is a bunch of logs I set aside as firewood.  I need to saw them up into lengths of 18" at most (that's what my stove will accept), and then haul them back to a wood pile that I've got going.  I have a wood splitter on the way, and once it arrives I'll split those logs up and pile the wood up in the shed's second floor, in the storage section.  There it should dry out over the summer very nicely, and give me a great supply of firewood for heating my office next winter.

Debbie and I had ourselves a homey dinner at Angie's.  We both had the special: a half dozen fried shrimp, potatoes, homemade dinner rolls, and iced tea.  We were way too full for dessert :)

To the great surprise of...

To the great surprise of ... exactly nobody other than the most credulous and uninformed progressives (i.e., 90% of them), ObamaCare's promised premium reductions are turning into giant premium increases!  Debbie and I are still stunned by our over-$1,200 a month premium (and that's for a plan with sky-high deductibles!), and we're reliably informed that we should expect a 25%+ increase for the coming year.

We feel very fortunate to be in a position to actually pay such a premium.  Several of our neighbors, including some with large families of young children, cannot afford any health insurance – even with ObamaCare's subsidies.  They go without any coverage at all, and rely on a well-established network here of cash healthcare providers and the safety net of the LDS church if someone had a catastrophic illness or injury.  If we didn't have the ObamaCare fine (for not buying insurance) hanging over us, we might do the same.  The LDS church provides that safety net for everyone, not just their members.  I like their system far better than I like ObamaCare (or, for that matter, any other form of federal welfare/involuntary wealth transfer)...

Mark Steyn...

Mark Steyn ... on the fifth anniversary of “Everybody draw Mohammed” day.  The lead:
Five years ago, a cartoonist with The Seattle Weekly, shocked by the way Comedy Central had censored "South Park" after the usual threats from violent Muslims, proclaimed May 20th as "Everybody Draw Mohammed" Day. What was novel about this particular promotion was that the cartoonist, Molly Norris, was not a "right-wing" "Islamophobe" but a liberal progressive, and therefore a rare if not all but unique example of a feminist leftie recognizing that the Islamic enforcers were a threat to her way of life. This was a very welcome development.

Unfortunately, Miss Norris was not so much recognizing reality as blissfully unaware of it. When the backlash against her idea began, she disassociated herself from it and signed off with - Lord help us - a peace symbol.
Do yourself a favor and read the whole thing.

The reflex to shut down free speech (and yes, cartoons are a form of speech) is one of the things that most disturbs me about progressivism.  They, of course, rarely acknowledge that they want to shut down free speech – they weave calming words around the notion, casting it as a right to be unoffended, rather than as a curb on free speech.  That's just a marketing ploy, though.  The reality is that they want you to stop saying whatever it is that they don't want to hear.

To which I say, “Fuck off, progressives!”

Memorial Day...

Memorial Day...  Many others have written of this day's meaning far better than I ever could.  I'll be burning brush today, and while I'm doing that I'll be thinking of the ones we honor today...

Geek: what takes 80 seconds to do a double SHA-256 hash?

Geek: what takes 80 seconds to do a double SHA-256 hash?  An IBM 1401 mainframe computer, that's what.  The bad performance isn't just because of slow clock speed – it's also down to the fact that the 1401 doesn't have a conventional binary ALU; instead it uses BCD math.  The logical operations in the SHA-256 algorithm are relatively easy with a binary ALU; they are horribly difficult using BCD. 

Even on the old computers I first learned to program on, I never had that particular problem – they all had binary ALUs, though they didn't use two's-complement math (they used one's-complement math because back then it was slightly faster).  I did, however, once have almost the inverse of this challenge: I implemented a BCD-based floating point package (complete with logarithms and trig functions) that ran on an Intel 8080 microprocessor.  This was made slightly more bearable by the built-in support for adding two BCD digits packed into a byte – but still, multiplication and division were quite painful.  And painfully slow...

Tired, I am...

Tired, I am...  The brush pile remaining turned out to be about three times the size I had estimated.  It took me all day simply to cut it up into (roughly) 6' long pieces and pile it up.  The resulting pile is 33' long, 6' wide, and about 4' high on average, after compacting by jumping up and down on it.  I've stacked it with branches all running in one directly so that I can pick it up easily with my tractor's fork (it's designed for pallets, but works great for brush stacked parallel).  I used two tanks of fuel on my chainsaw to do all the cutting.  I didn't actually burn any today; that will be tomorrow's job if the weather holds.

When I'm working with the chainsaw, I am careful to work only when I'm not dog tired.  I always wear my safety gear (helmet, hearing protectors, face screen, Kevlar leggings, Kevlar gloves, and steel-toed heavy leather boots).  The locals all look at me a little funny in this get-up.  I strongly suspect that none of them have ever even seen this safety gear, much less used it.  Manly men wouldn't stoop to such aids :)  I couldn't care less about the appearance, but I care a lot about keeping as many parts of my body intact as possible.  I've seen the videos showing the Kevlar leggings and gloves at work; I find those videos quite persuasive.  The boots seem commonsensical, as there are times when the end of the chainsaw blade is down near my feet.  The helmet with its integral hearing protector and face screen is actually very convenient, as is the absence of saw-ejected sawdust and wood chunks in my eyes.  Besides, the get-up is only confirming what the neighbors have already figured out: I'm not normal (at least, not by their standards!).

Anyway, I took a half-dozen or so breaks during the day, before another bout of chainsaw work.  During these breaks, I perched myself over the irrigation canal bank, under the shade of a big old black willow tree.  The burbling of the slow-moving canal was pleasant, as was the sight of the water.  The birds, though, were a great entertainment.  The trees along the canals are hosts for quite a few nests, all of which are occupied by hungry babies at the moment.  I watched as four pairs of robins, two pairs of red-winged blackbirds, an uncountable number of house finches, two pairs of warblers (unidentified), one pair of Bullock's orioles, and a pair of something that looked a grosbeak all worked hard to feed their babies.  Under our bridge, a hundred feet or so away, were the nests of about 20 pairs of barn swallows, also busily feeding their babies.  A pair of mallards swam along the canal, no babies behind them yet – probably soon, though.  All of these birds – most especially the robins and the blackbirds – were hollering away at me.  They were most seriously displeased, to steal a favorite phrase from Jane Austen.  I was pleasantly entertained.

As I worked away, several people honked in greeting.  I don't know who they were; I couldn't see them and I didn't recognize the cars.  Two cars actually stopped to see if I needed help.  One of those people was someone I'd never met before; the other a person I'd met once in the Paradise Post Office.  Both offered to run home, throw on some sacrificial clothes, and then come back to wallow in the mud with me piling brush.  I told them I was fine on my own, and to keep their Sunday something fun – but the offers sure put a smile on my face. 

After I finished piling all that brush, I took our three dogs out for a half-mile walk up the dirt road that runs east from our house.  It was a lovely late afternoon, with puffy clouds covering perhaps half the sky, leaving lots of sunlight all around us.  The hills to our west were a beautiful dark green in various shades, different crops being slightly different colors.  There was a slight haze in the air that layered a dreamy sort of look over the whole scene.  We could hear horses snuffling, cows mooing, sheep baaing, and dogs barking.  Barn swallows swooped all around us, no doubt catching food for their babies.  As we walked by our neighbor's pasture, the four horses within came trotting over to see us – we're all becoming friends now.  Even the dogs stick their noses through to greet them.  A half mile or so away, I could hear one of my neighbors to the south mowing her small lawn behind her house.  A little north of our place, I saw another neighbor stringing out hand line (irrigation pipes that you carry by hand, in 30' long pieces), preparing to irrigate.  That seems a little premature to me, but maybe he just wanted to be outside on such a gorgeous evening.

I love living here...

Mark Steyn at his best... and that's pretty damned good!  Movies and politics mix well in his hands.  A small sample that had me spitting out my morning tea:
The nearest they got to solving the problem was in Primary Colors (1998). The Bill Clinton character was played by John Travolta at his most ingratiating, whereas Hillary was such an unsympathetic character that, as with Hannibal Lecter or the Die Hard terrorist masterminds, they had to fly in a Brit to play her. The role went to Emma Thompson, presumably because Alan Rickman and Jeremy Irons turned it down. (If memory serves, Rickman drew the line at the prosthetically enhanced ankles, although he'd totally nailed the robotic voice that tells you to fasten your seat belt.)

Seven people I've known ... are on this wall, including one I called “friend” and another “mate”, both from my service in the U.S. Navy.  Actually, it's possible there are more that I'm unaware of.  My friend was a hospital corpsman I met in boot camp, killed in 1972 while treating a U.S. Marine injured in combat (the Marine survived).  My mate was a fellow DS (data systems technician) who served on PT boats, then became a DS, and then volunteered for another “tour” on PT boats.  He was killed in a firefight along a river just 25 miles northeast of Saigon in the last days of American involvement in the war.

I think of them both every year around this time, along with the thousands of others who were casualties in America's many wars...

Progress in Paradise...

Progress in Paradise...  Looks like we have a cloudy, but dry, morning.  I'll be heading out soon to (I hope!) clean up the last of the brush left behind by the Mormon horde one week ago.  I'll likely be very tired when I get back in, so blogging will be iffy today.

Debbie and I watched more television yesterday than I have in quite a few years now.  We've been intermittently watching a British series called Foyle's War, set in England from WWII through the early Cold War years.  Stuck inside on a rainy day, yesterday we watched the last three episodes of the entire series.  We've quite enjoyed these.  The acting is excellent, the story lines intriguing (especially for anyone who loves British mysteries), and the production quality is very high.  While they took a few liberties with actual history, for the most part the events depicted are completely consistent with reality.  Most of you know that I watch nearly zero television.  For me to watch an entire series, it has to be particularly well done, and on a subject that appeals to me.  Foyle's War hit the mark especially well.  Highly recommended!

We have a bit of Mo'i news, or perhaps more accurately, preliminary Mo'i news.  He's our 16 year old field spaniel, who just a few months ago was struggling and (we thought) near the end of his rope.  In January he developed a strange condition that had no organic cause that our veterinarian could detect: he started compulsively drinking, and as a result, urinating uncontrollably.  We started putting diapers on him, and that cured the problem of urination in the house – but of course that was merely treating the symptoms. 

A few weeks ago, we noticed that his compulsive drinking seemed to be tapering off.  Shortly thereafter, wet diapers started tapering off as well.  Finally, two days ago, he hit a milestone that I was watching for: 3 weeks without a wet diaper.  So yesterday, for the first time in five months, we let him go all day without one.  No “accidents”.  With a little trepidation (as waking up to a urine-soaked kitchen is not high on our list of preferred awakening modalities), we left the diaper off last night.  This morning he woke me up later than usual (at 4:30 am) with his “I have to pee!” bark, and I took him out for his morning walkie.  The kitchen was unsullied. 

So for reasons we have no way to discern, Mo'i's odd thirst and urination issue looks like it might be over – just a strange five month episode in his life.  Meanwhile, he is in much better physical condition now than he was in January, thanks to walks we've been taking with him.  We'll do a mile or so this morning, something he simply could not have done in January.  One theory we have about the odd behavior is that it was some kind of response to the stress of moving to Utah.  If so, it was a stress our other dogs felt none of – they (very obviously) couldn't be happier to be in this land of cool, green grass.  It's harder to tell with Mo'i – at his age, his cavorting days are over.  The stress theory is just a theory, though; really it's just a correlation between his behavior and the timing of the move.  But we have no other theories.

In any case, to have our relatively normal Mo'i back with us is a joy that we're cherishing while we have it.  At this moment he's in much better condition than when we left California, is clearly enjoying his life up here, and has no bizzaro behaviors.  We'll take that!

Storm total...

Storm total ... is 2.85 inches, as of 7 pm this evening.  We still have more rain in the forecast, too – tomorrow afternoon through Thursday.  Our fields are saturated, and the baby alfalfa plants are practically leaping for joy, while the rye and orchard grass is growing almost visibly.  What a difference from the desert of California!

Raindrops kept falling on our heads...

Raindrops kept falling on our heads ... nearly all day long.  It stopped around 2 pm, but now (at 5 pm) it looks like it's going to start again.  I didn't have a chance to work outside today at all.  Maybe tomorrow morning.

Debbie and I took a drive up to Hardware Ranch today, and a few miles beyond.   We saw a male Lazuli Bunting, a gorgeous male meadowlark, and – best of all – a pair of Sandhill Cranes with two chicks, much like the photo at right (which isn't mine).  We sat and watched the four of them for quite a while, enjoying the show.

We picked up the mail on the way home, and in there had quite a surprise.  Just a week ago Wednesday, Debbie and I got our cars registered in Utah.  Debbie ordered a custom plate for her truck, and the clerk there told us it would take 6 to 8 weeks for them to arrive, along with her new registration (the standard plates they just handed us on the spot).  Then they issued us a temporary registration good until July 31st.  Well, her new plates showed up today.  That's ridiculously fast – just nine calendar days, and seven working days since we ordered them.  And that includes delivery by U.S. Post Office, which may well have eaten up half of that!

We love living here!  It's like the exact opposite of the dysfunctional California DMV.  Anyone who lives there can tell you that to get your custom plates there is going to take a lot longer than that – and you'll be lucky if they don't screw it up...

Precomputation renders Diffie-Hellman vulnerable...

Precomputation renders Diffie-Hellman vulnerable...  The Diffie-Hellman key exchange algorithm is at the heart of a great many cryptographic systems, including those that you likely use every single day.  News that it may be vulnerable isn't exactly comforting, even when that vulnerability costs hundreds of millions of dollars to exploit.  That cost is only going to go down, too.  Today only a major state actor (like, say, the NSA or FAPSI) could afford this, but that could change relatively quickly.

The new attack is enabled by the use of an enormous table of precomputed partial results for a particular prime number used in the Diffie-Hellman scheme.  The details aren't important to understanding the vulnerability.  The key is that you need one of these tables for each possible prime number being used – and that most Diffie-Hellman implementations use one of a very few number of such primes.

There are three main mitigations available, but both are going to be challenging to roll out.  One mitigation is to use longer keys (this always seems to be the mitigation for a vulnerability!).  Another is to stop using the magic few prime numbers, and switch to using frequently generated prime numbers. The last is to quit using classical Diffie-Hellman. 

It will be interesting to watch how the world reacts to this.

Much more technical information in the original paper, and here, here, and here...

Robot employment act...

Robot employment act...  The image at right is from the article The Robot Employment Act? on Marginal Revolution.  The article discusses in some detail how a rising minimum wage causes an increase in automation (robots).

The economics of this are very straightforward.  Take a job that needs to be filled 24 hours a day, 7 days a week (typical for a factory job).  That's 21 shifts (8 hours each) per week.  To hire a minimum wage worker at $15 per hour costs the employer $131,040 per year in direct wages, plus roughly $25,000 more in social security, unemployment insurance, etc.  Call it $150,000 a year.  That actually understates the cost a bit, because there is more overhead associated with management, human resources, parking lots, break rooms, rest rooms, etc.  We'll ignore all that (though it's actually not insignificant). 

What does a robot cost?  Well, that depends entirely on exactly what that minimum wage worker was doing.  Some jobs are very easily handled by robots: repetitive assembly work, welding, parts painting, etc.  Some are less easily handled: short order cook, maid, house painter, etc.  These are difficult precisely because they require (or seem to require) human judgment, analytic capability, and motor skills.  However, progress in these areas is happening very quickly.  There are, for instance, fully operational short-order cook robots right now.  They don't look anything like the photo above; they're more like automated stoves with food and implement handling capability.  But they work, and they cost about $300,000 - plus $20,000 or so a year in maintenance and power.  Ask any businessman what he'd choose: a worker who costs $150,000 every year, or a robot that costs $300,000 up front and $20,000 a year thereafter, and you'll get the answer very quickly.  The robot wins!

If it isn't blindingly obvious why that's so, consider the 10 year cost of the worker versus a robot.  The worker would cost 10 x $150,000, or $1,500,000.  Ouch.  The robot would cost $300,000 + 10 x $20,000, or $500,000 – just one third the cost of the worker.  Furthermore, the robot is going to get cheaper and cheaper over time, and the worker ... will get more expensive.

This is how robots are going to take over.  They're going to be the cheapest way to get something done.  The minimum wage raising accelerates this process by forcing workers to cost more – and precisely the class of workers whose job is most easily automated.

Jeff Bezos at Amazon, with his robot armies in his warehouses, is leading the way...

Rain drops in Paradise...

Rain drops in Paradise...  I thought I'd be working outside this morning, finishing up the brush burning.  As I write this, it's gently raining in Paradise, and the weather radar shows more on the way.  It might be just a tad wet out there for a while!

Yesterday afternoon, my rain gauge was showing 2.4 inches for the storm total.  It's been raining since about 8 pm last night, so we're probably getting close to 3 inches at this point...

Progress in Paradise...

Progress in Paradise...  This morning saw fine weather again, so I headed out early to burn some more of the brush collected by the Mormon horde last Saturday.  I made good progress, getting about half of the brush burned.  The remaining brush should be easier to deal with, as it's quite a bit smaller diameter, on average, than the stuff I've already cleaned up.

The fire today was quite hot – hotter than I realized at first.  When I got done for the day, my glasses were hard to see through.  I cleaned them, to no effect.  Only then did I notice that the heat had distorted the surface of both lenses, in a spot near the center and covering about a third of the lens.  I can see clearly through the top (distance) and bottom (near), but in the center it's all fuzzy.  Who knew that plastic lenses were less resistant to heat than my own skin?

After finishing up with the burning for the day, I drove Debbie's truck down to Hyrum Tire to get the new rubber installed.  I'm really impressed with these guys.  I drove in without an appointment.  They asked if I was going to leave the truck or wait for it to be done.  When I indicated the latter, they swarmed my truck with three workers (see photo at right).  In no time at all they had the truck up on a lift, and all four tires removed.  They had two tire machines plus a balancer going, and very quickly had the old tires off the rim, new tires on, balanced, and mounted back on the truck.  It was fun to watch a competent bunch of guys do their thing.  They teased each other and bantered away as they worked.  Competent workers, good advice, cheerful folks, quality products, and good prices.  Pretty hard to beat!

After that it was off to Macey's grocery store to pick up some essentials for Debbie and I.  She's making chicken soup, hoping that the “Jewish penicillin” will conquer the virus that's giving her a sore throat.  She's making her usual 5 gallons, so I will be the accidental beneficiary of this effort :)

Partly cloudy, no rain in sight until early this afternoon...

Partly cloudy, no rain in sight until early this afternoon ... so I'm headed out to burn some brush piles.  Got my burn permit in my pocket, and I'm going to fire up the tractor after I take the dogs for a walk.  Debbie's out with a cold, mostly manifesting as feeling like crap and a sore throat.  Sure hope she doesn't get the nasty cough she's prone to...

Progress in Paradise...

Progress in Paradise...  If you're one of those people who are so bored with life that you actually read this blog regularly, then you'll remember when the Mormon horde descended on us.  Last Saturday morning, a small army of my neighbors descended upon us, armed with chain saws and muscles more bulging than mine, and cleaned up an enormous amount of brush and dead wood.  The only thing the left behind was ... a dozen or so prodigious brush piles.

This morning the weather was unexpectedly fine, so Debbie and I set out to burn said brush piles.  We set up a water line, armed ourselves with matches and paper to start a blaze, a pitchfork, and drove the tractor out to a spot near the southeast corner of our property.  This spot is on the peninsula formed by a bend in the irrigation canal, and it's a long way from any structures or trees – a perfect spot for a burn.  It was also conveniently close to about half the brush piles left behind by the Mormon horde.  We put a bit of brush on the spot and in short order we had a nice blaze going (photo above).  The fire was so hot that I couldn't get closer than about six feet to the brush pile, unless I was willing to have my beard burned off (which I was not). 

We worked as hard as two ancient and decrepit people could, for about 5 hours, until we could plausibly say that rain was threatening us.  At that point we sat down and didn't get up for about an hour, while pretending to watch the fire closely.  Since everything for about 100 miles in every direction had just been soaked with almost 2 inches of rain, in reality there was no fire danger at all.  But our burn permit required us to remain in attendance, so we had our excuse :)

As I write this, I'm about to stagger off to my bed to rest my weary bones.  With any luck at all, tomorrow morning we'll get up and do it all over again.

Oh, and we burned about one fifth of the brush.  We have quite a bit more work to do!  And we are also learning in a very direct way just how much that Mormon horde accomplished on a rainy Saturday morning...

Paradise update...

Paradise update...  Well, Jimmy and Michelle B. are on their way home.  We had breakfast together at Herm's this morning, and then they set out for St. George.  We had a lovely day with them yesterday. 

First we drove out to Hardware Ranch and partway to Ant Flats.  On that trip we saw a beaver working on his dam, a half dozen or so kingfishers, and an osprey gnawing on a fish atop a power pole, while a magpie tried to steal the fish away.  On the way back down from Hardware Ranch, we took the Left Hand Fork road and moseyed along it for 5 or 6 miles.  That's a beautiful drive in a steep canyon with a burbling brook at the bottom, and there are trails galore that leave from it.  This area is just 30 minutes or so from our house, and I suspect it will take us several years to explore it all. 

After this, we drove down to Porcupine Reservoir as far as the road would take us.  I was hoping to share the loons with Jimmy and Michelle, but we didn't see a single loon anywhere.  We did see lots of baby farm animals though: goats, horses, cows, and sheep. 

After this we headed over to Brigham City to have dinner at Maddox House.  On the way down toward Mantua in Sardine Canyon, traveling at 60 MPH, we had a special surprise: a tire failure.  Our left front tire started making some odd noises, then just a few seconds later it disintegrated – lots of loud noises and smoke.  The truck was perfectly stable through the tire issue; slowing down, driving off the road, and stopping were no problem at all.  The ABS system kicked in when I turned to leave the road, and it worked perfectly – we were rock-solid stable throughout.  We piled out of the truck and went to work to change the tire.  Partway through this effort, a sheriff pulled up: Brian Nelson.  He was incredibly friendly and helpful.  First he lent us a star wrench, which was much easier to use than the single-handled wrench that came with the car.  Then when I ran into a lug nut that I couldn't break loose, he got on the wrench with me until we got it going.  He helped raise and lower the jack.  When we were all done, he brought out some clean-up towels to get the worst of the grime off our hands.  We all left the scene with big, happy smiles on our faces.

But those smiles were soon supplanted by moans of gustatory pleasure as we dug into our meal at Maddox House.  Between the four of us we had filet mignon, ribeye steak, fried chicken (me!), and salmon.  All was delicious, as were the accompaniments: homemade rolls, raspberry butter, carrots, birch beer and sarsaparilla.  None of us had any room for dessert, dang it. Someday I'm going to get to try one of their fruit pies!

After we staggered back home, holding our bellies to salve the pain of being so full of good food, we had a fun evening playing cards.  The four of us teased each other and laughed for hours, and we didn't retire until way past my usual bed time.  Jimmy and Michelle promised to come up again, sometime later this year, for a longer visit.  They also volunteered their slave labor to help around the place, a promise which I am certain they will regret!

Hiatus in Paradise...

Hiatus in Paradise...  No progress yesterday, as we had friends visiting: Jim and Michelle B.  They arrived late on Sunday, and they'll be here through Wednesday morning.  Blogging will be light to non-existent :)

Sunday we all went to Angie's for a local style supper.  Yesterday we drove south from our home, through Paradise and Avon, then up and over the pass (on a four-wheel dirt road) to Liberty and Eden.  That was a beautiful drive.  It was overcast but not raining, and we traveled through lush greenery, lots of flowing water, and spring flowers.  The blue larkspur at around 6000' was my favorite.  In some places there were patches six feet or so across that were solid blue.  Michelle spotted a pair of Sandhill Cranes foraging in a meadow.  We also had a nice viewing of a blue heron, and a couple of does.

We went to the Red Iguana in Salt Lake City for our supper, and a fine meal was ours.  I'm still not hungry :) We're going to do some more driving in the mountains today, then we're headed to Maddox House for a BEEF dinner tonight!

While we were gone yesterday, we got another three tenths of an inch of rain.  The storm total (since last Thursday) now stands at 1.7 inches.  Woo hoo!  We're going to be driving past Porcupine Reservoir today – we're hoping it's full now, or nearly so...

1.2 inches...  That's the storm total so far...

Tired and sore in Paradise...

Tired and sore in Paradise...  My workout with the Mormon horde yesterday pushed my muscles and skeletons a little further than they wanted to go :)  I'm going to take the day off from any physical work today.  I need to recover!

We had a very nice dinner last night with Sheila Miller, her sister, and a good friend of theirs.  We met at Cafe Sabor, and as usual, the food was very good.  The friend and I were the designated drivers.  The other three hogged down multiple flagons of alcohol mixed with various things to disguise its flavor.  By the time we were ready to leave the restaurant those three were ... very happy.  The evening was full of good conversation and funny dog stories.  Sheila's sister (Debbie) is a gifted storyteller, at least when she can keep track of the story line.  That got harder after the first margarita :)

When we left for the restaurant, our storm total rainfall stood at 9/10ths of an inch.  It rained the entire time we were gone, sometimes hard (according to the weather radar).  As soon as it's light this morning, I'll check the gauge – but I'd bet we're well over an inch now.  There is much relief amongst the farmers here, who have all been quite worried about the possibility of severe drought.  That doesn't appear to be much of a concern any more!

Quote of the day...

Quote of the day...  Mitt Romney, after The Quake on the Lake:
“Please, please champ, don’t beat my brains out – because if you did, I’d have to become a Democrat.”
I don't like to think about what it might have been like to have a President Mitt Romney instead of a second Obummer term, because cry...

My mother-in-law made the front page...

My mother-in-law made the front page ... of the web site for the nursing home she's in.  That's her in red at right.  Like many in her condition, she has good days and not-so-good days.  She's physically fragile, too; not a great combination with dementia.  Little injuries, often completely mysterious, seem like almost a daily occurrence – and serious injuries have occurred several times in the past few years.  I hope she's not miserable all the time.  It worries me that we have no way to find out, really, how she's feeling.  The folks at the nursing home have mostly been great, with just a very few instances where we suspected the care was anything else.  But even the people caring for her every day can't reliably tell how she's feeling.  The dementia makes everything about her care very challenging...

A pleasant surprise...

A pleasant surprise ... was ours last night, when we learned that Sheila Miller (the proprietor of Wolftree Acres, and the breeder from whom we got all three of our field spaniels) would be in nearby Logan this weekend.  She's at a dog show happening in the fairgrounds there, and we're hoping to be able to have dinner with her tonight.  Sheila keeps threatening to stop breeding (it's a LOT of work!), but we're hoping she'll do it at least one more time – as we'll probably be looking for another puppy in a year or so...

This is turning out to be a highly social weekend for us.  First the Mormon horde, then Sheila, and (allegedly) our friends Jim and Michelle are showing up tomorrow.  Woo hoo!

Despite the cold drizzle...

Despite the cold drizzle ... the Mormon horde showed up and went to work.  In just four hours they got more done that I could have done myself in a year of part-time (hard!) work.  All the old barbed-wire fence is down and hauled off to the dump.  Nearly all of the dead limbs have been cut down, cut up, and piled up ready for burning.  There are just a few branches left that were too high to reach without ladders.  The trash in the old dry canal bed has all been dug up and hauled away.  It's amazing how much got accomplished!  People came and went all morning, but overall I think about 15 people contributed.  There were a half dozen guys with chainsaws, we had a nice big hydraulic dump trailer for hauling, and a neighbor with a 40-horsepower tractor came over to do the heavy lifting and pulling.  The only real challenge we ran into was an old corner post made from cinder blocks and reinforced concrete.  We managed to knock it over, but we couldn't lift it or break it up.  That will have to wait for another day...

Debbie had a nice meal waiting for us when we finished: chicken salad sandwiches on nice buns, with tomato and lettuce, chips, cookies (her homemade chocolate chip cookies with cranberries and orange), and lemonade.  The sandwiches and cookies were a big hit – they disappeared quickly, though Debbie of course made way more than we could possibly eat :)

Now that we're done, I'm all sore and creaky.  Those guys were all way younger than I, and in trying to keep up, I think I've strained ... everything.  No more working for me today!


A boy, a truck, and two flags...

A boy, a truck, and two flags...  Nice story.  It would be different here in Utah.  I can't imagine the local school behaving this way here.  And none of my neighbors are complaining about my flagpole and flags...

False memories...

False memories...  I first started reading about this phenomenon in the '70s, and I'll note that the more research on it that's done, the more common the false memories turn out to be.  One study I read recently said that of 150 people whose memory of a vivid incident was tested one week later, even when they were tasked with remembering it accurately – 100% of them had “significant” errors in their remembered chronology or list of events.  One hundred percent, and the group included over a dozen people whose job required accurate memory.  By far the most common error was addition, not omission – meaning that chronologies were changed or events that didn't actually happen were added.  Another thing that seems clear from the studies: emotionally charged incidents (which the previously mentioned study used) are far more likely to be mis-remembered.

Fallible, we humans are...

Today is the day...

Today is the day ... that the Mormon horde shows up to clean up our canal area, as a service project.  However, the weather isn't looking very cooperative: heavy rain is predicted starting at around 9 am, and the weather radar in fact looks a little ... ominous.  The leaders were here last night doing some final planning, and noting the weather they decided to start this morning at 7 am.  I'm not sure how long they're going to last – if it starts getting wet, we've all agreed they're going to pack it in and reschedule...

Quote of the day...

Quote of the day ... anthropogenic global warming skeptic edition:
What I would like to emphasize is that human actions have very large effects on the ecology, which have nothing to do with the climate. Carbon dioxide is what we're producing in big quantities and putting into the atmosphere. This happens to be a very good fertilizer for all kinds of vegetation, good for wildlife, good for agricultural production, so it has many benefits. And this is something you have together with the climate effects, which are much less certain, so it's a question of drawing a balance. I'm just saying I don't understand it and neither does anybody else. I'm skeptical because I don't think the science is at all clear, and unfortunately a lot of the experts really believe they understand it, and maybe have the wrong answer.

Of course [the weather] concerns me, but of course, we don't know much about the causes of those things. We don't even know for sure whether it is more variable than it used to be. I mean the worst disasters were the Ice Ages, and nobody really understands for sure the causes of Ice Ages, so I'm not saying the climate disasters aren't real, I'm merely saying we don't know how to prevent them.
That's Freeman Dyson, in a quote from an interview about his new book...

Fun with big data...

Fun with big data...  On this web site you can check the popularity (in America) of just about any given name.  The site has a disclaimer for data prior to 1940.

The chart at right shows the result for my own given name (“Thomas”).  You can see that “peak Thomas” (the raw data is downloadable) was in 1952 – the year I was born.  I've always assumed that I was named after my dad, but (perhaps coincidentally) my name was also at its peak popularity that year.

The chart at left shows quite a different result for “Holly” – my sister's name.  Even at its peak (in 1983), “Holly” wasn't nearly as common as “Thomas” – but in 1955, when my sister was born, it was much less so.

My wife's given name is Deborah, and when I checked her name the results were even more dramatic (at right).  “Peak Deborah” was in 1954; she was born in 1955, and at that point the name was more popular than “Thomas” for boys.  But prior to 1944, there were almost no women named Deborah!  And these days, newborn girls are only rarely named Deborah.

I tried about 20 names from my family or Debbie's, and the results were quite a surprise to me.  Try some of your own, and if you find something surprising, leave a note to tell us about it!

The first one on that list has long fascinated me. I've seen maps showing where people move after retirement, and in fact is is highly unusual for people to move north (as we did!). I've forgotten the exact ratio, but it's on the order of 6:1 in favor of moving toward the south...

Progress in Paradise...

Progress in Paradise...  Three hours – that's what it took to work out all the changes required for our insurance yesterday.  I (naively) thought that transferring our car insurance from the carrier we used in California to our new carrier in Utah would be simple and easy.  Oh, no.  No way!

First, there are about six zillion options on car insurance.  It's been many, many years since I last reviewed car insurance in detail – I've just sort of been on autopilot while I was working.  It never seemed like it was worth bothering with.  After a couple hours of working at it, we've now got coverage that's better suited to our needs – and we're spending less money to get it.  Win! 

That was only part of the complication, though.  Another twist was my discovery that standard car policies don't cover the use of a trailer.  Adding coverage for the trailer was cheap – but I had no idea I even needed it!  Then there was the coverage for the shed.  The structural coverage was easy enough, but the contents are another story.  There are different coverages needed for tools, ATVs, and tractors.  Tractor attachments fall into a gray area.  This all took time to sort out. 

Then there were a bunch of discounts available for certain combinations of coverage (especially basic homeowner and automobile).  When I left, there were still a few unresolved issues – liability umbrella and some details around tractor coverage.  So I'm not quite finished with the insurance mess yet :)

One thing that surprised me: the agents were unfamiliar with high deductible rates.  On talking with them, I found out that nearly all their clients want policies with the lowest possible deductibles, apparently unaware of just how much more expensive such policies were.  Even the agents seemed unaware of how much less expensive high deductible policies were.  For someone like us who very rarely make claims on homeowner or automobile policies (two claims in 45 years!), the savings on high deductible polices is substantial.  We did the same thing on healthcare insurance, for the same reasons.

The rest of the day Debbie and I installed new fixtures in the upstairs bathroom.  We didn't quite finish, but we'll do so today.  The new stuff looks way nicer than the old!  The faucets operate with a satisfying smoothness and solidity; the old ones were creaky and felt like you were sliding pieces of plastic against each other (which probably is exactly what they were)...

Heisenberg's Theorem on Green Energy Measurement...

Heisenberg's Theorem on Green Energy Measurement...  My three long-time readers will know that CoyoteBlog, by Warren Meyer, is one of my daily visits.  He's been on a roll recently with a series of excellent posts.  This morning, before I got to my morning blog reading, my friend Doug W. emailed me about a really good, short post there.  He took unfair advantage of the time zones, as he's currently traveling in Italy :)

Mr. Warren is many things, but a world-class speller is not amongst them :)  I've taken the liberty of correcting his spelling, and quoting his awesome post in its entirety – it's way too short to be excerpted:
Heisenberg's Theorem on Green Energy Measurement

Theorem: A media article on a wind or solar project will give its installation costs or the value of its energy produced, but never both.

Corollary 1: One therefore can never assess the economic reasonableness of any green energy project from a single media article

Corollary 2: For supporters of green energy, there is a good reason for Corollary #1.
The media and the greenies, in bed together.  The result is pretty bad...

Wait, what?

Wait, what?  I saw this headline and feared that Utah had done something stupid to interfere with business:
Contested Utah law could impact contact lens industry
On reading the article, though, I discovered the exact opposite: Utah has acted to prevent the contact lens business from fixing prices artificially high.  They are removing a barrier to getting lower prices for consumers.


Yay, Utah!

Kinetic sculptures in wood...

Kinetic sculptures in wood...  Completely by accident, this morning I ran across the work of David C. Roy.  The video at right shows one example; more here and here.  I find these sculptures both beautiful and fascinating. 

Mr. Roy limits his sculptures to purely mechanical motion (springs, weights, etc.) and eschews anything like an electric motor.  Personally, I don't think they'd suffer if motorized.  Beautiful things!  And it makes me wonder if I could do something like them...

Progress in Paradise...

Progress in Paradise...  Yesterday we finally finished the maze of paperwork, inspections, etc. required to transfer registrations of our vehicles from California to Utah.  Now when we travel about the area, we won't have the locals looking at us and wondering who the hell let these damned Californians in here!

I started working on replacing all the fixtures in our upstairs bathroom.  When we bought the house, that bathroom was equipped with rather cheaply made chrome faucets, drain, towel racks, etc.  They were also badly installed (just screws in wallboard).  I'm replacing the whole kit and caboodle with much nicer fixtures in an oil-rubbed bronze finish.  One sink and surrounds are finished, and they look quite nice.  Works well, too.  But ... I have kinks in my back and side where I shouldn't outta have them, thanks to all the under-sink work :)

“Caboodle” is an interesting word.  It's American slang (according to the OED), dating back to at least 1848.  Every reference to it is from American magazines, newspapers, or books.  That means it's one of those words you can use to confuse a Brit!

Paradise perambulations...

Paradise perambulations...  We had two very nice walks today with the dogs.  They seem to still be in a state of disbelief that this area is now their home – a place with green grass (and alfalfa!) to run around in!  Race is very curious about the irrigation canal along the east edge of our property – he likes to watch the moving water, along with the swallows and red-winged blackbirds.  Photos and a couple of short videos below...




Oh, this felt so good...

Oh, this felt so good...  Throwing away our California license plates, that is.  Those were the last vestige of our former residence.  We have Utah plates now, and Utah titles are on the way.  Woo hoo!

Progress in Paradise...

Progress in Paradise...  Yesterday morning I managed to get myself almost completely covered with light grease.  This happened as I was unpacking and assembling my new Grizzly jointer (at right).  If you're not familiar with this tools, they do something kind of magical: they put a perfectly straight, flat surface on the edge or face of a board (in the case of mine, up to 6 inches wide).  The top part of it weighs about 150 pounds, a bit too heavy for me to lift onto the stand safely by myself.  So I rigged it up to my engine hoist, and in the process the preservative grease on the milled surfaces got everywhere.  The fence was light enough for me to lift by hand, but that just spread more grease around.  The final straw: the fence carriage's milled surfaces had been painted over in manufacturing, and I had to scrape and steel wool all that paint off – and naturally, it was completely covered in grease, too!  I smelled like a tub of petroleum by the time I finished all this.  On the other hand, I now have a really nice jointer!

Debbie and I went out to lunch at Jack's Wood-Fired Pizza.  I've blogged about this place before – it's got weird and wonderful pizzas with magically good crusts.  I had the “chuck wagon” pizza – barbequed pulled pork with pineapple – scrumptious!  Debbie had one with pepperoni, sausage, and jalapenos; she pronounced it wonderful.  To my surprise, Debbie also ordered dessert (something I'd never had there before).  She got a huge slice of lemon cake, and it was as good as I've ever had.  The cake itself was delicious, but the lemon filling was absolutely superb.  It was lightly drizzled with a not-too-sweet icing, and garnished with perfect fresh blackberries and raspberries.  I was full from the pizza, but I still managed to eat some of that...

We were up in Logan to visit Campbell Scientific company.  They're the manufacturers of the Weatherhawk weather stations – a lucky coincidence for me.  I ordered one last week, and they offered to let me pick it up rather than ship it a mere 12 miles.  I got a model 621, pictured at right, with no moving parts in it all all.  The wind speed and direction is sensed by an array of ultrasonic sensors, and precipitation (rain or snow) is sensed by an upward pointing radar.  The unit is quite a bit smaller than conventional weather stations, and (best part!) has no regular maintenance requirements.  I'm going to be mounting it about 200' north of my shed, where the properties of two of my neighbors intersect with mine, with open fields for at least 200' in every direction – a perfect location.  It will be solar powered (another project!) and it will talk with my server via 918 MHz radio, so there is no need for any wires running out to where I'm mounting it.  With any luck at all I'll have it rigged up within a couple of weeks.

Yesterday afternoon I mowed about half our yard.  It's been two weeks since the last mowing; all the rain has kept the yard so soft I didn't dare run the mower over it.  In areas where there's full sun, the grass had grown up to about 6 or 7 inches high.  I had to go very slowly in those spots so the mower could digest all that :)

Amazon Dash teardown...

Amazon Dash teardown...  We signed up for the Amazon Dash button a while back, but we haven't received any of them yet.  If you're not familiar with this widget, it's just a little button that you can click – and when you do, the product associated with the button is automatically ordered for you.  A day or two after you click it, your UPS delivery person will drop it at your door.  The general notion is that for products you order repeatedly (for us, coffee, tea, dog food, cat food, etc.) the process gets tremendously simplified.  I don't actually find this hugely compelling – ordering something on the Amazon website isn't exactly difficult – but it is kind of interesting to a geek to see how Amazon managed to reduce the whole process to a single click.

This fellow went one step further.  He actually received his Dash button, and promptly took it apart to see how it works.  Sometimes I just love the Internet :)

What he discovered is much as I'd expect: no magical innovations, just an exploitation of Amazon's scale to reduce the cost and size of a fairly complex gadget (really a small WiFi-equipped computer) to the point where giving it away is actually feasible...

Buttons that do nothing...

Buttons that do nothing...  An interesting article from the BBC about buttons and other controls that do absolutely nothing, but make people feel better anyway.

This is not new understanding.  Back in the early '80s, a customer for my design consulting practice introduced me to the same idea.  The customer was a firm in San Diego that built specialty radios, mostly for the commercial maritime trade.  These were sturdy devices that internally were quite advanced systems, but were being used by fisherman, cargo ship crews, and the like – not technically advanced folks, typically.  They also didn't have the habit of being gentle with their gear :)

I was contracted to build the first radio receiver they'd ever produced with a digital front panel.  The company's own engineers were analog folks, so they hired me to design all the digital parts as well as the interface to the analog side.  Most of this was very straightforward.  One seemingly simple element was the volume control.  Back in those days, controlling volume digitally was a bit of a challenge.  One couldn't simply go out and buy something like an 8-bit digital-to-analog controller (DAC) at a reasonable price.  So we decided to settle for a 3-bit DAC made from discrete components.  This provided 8 volume levels, which the company decided was more than sufficient – most users would simply turn it to the max, and leave it there.  I designed in an 8 position rotary switch that provided a click-stop at each of the 8 possible volume levels.  It worked great.

The company took our prototype and sent it out on a boat with a real customer to get feedback.  Mostly the feedback was very positive, to the delight of the entire team.  But ... the customer hated the volume control.  He claimed that the volume he wanted was always directly in between two of the click stops.  I was dismayed, and foresaw a difficult challenge – one that would likely bust the production cost budget.  The founder of the company was unperturbed, though.  He told me to put in a switch with no click stops, just smooth continuous motion.  To do this, we had to switch to a gray-coded DAC (to avoid glitches at the switch points), but that was relatively easy and cheap.  Then we sent the prototype back out to the same customer for testing, with a couple of other minor changes.

The result?  The customer was totally pleased, and reported that the volume control now worked exactly as expected.  Several follow-on testers reported the same thing.  Note that there was no actual change in function – the only thing we did, functionally, was to remove the click-stops.  The smooth motion of the switch now gave the customers the illusion of analog control, but the reality was they still had just eight discrete volume levels.  Customers were happy, and so was the company that employed me, as the new design actually turned out to be slightly cheaper to build.

I've remembered that incident ever since, and I confess that I've employed the same technique several times since then.  It worked every time.  I'm sure I've been fooled (and satisfied) by non-functional controls myself, many times.  We humans are funny beasties, aren't we?

Is it proper for women to be learned?  That's a question from an advice column of the 1690s.

Oh, the blue sunsets of Mars!

Oh, the blue sunsets of Mars!  As seen by Curiosity, in the colors you'd see if you were there.

I remember reading a science fiction story from the '60s or '70s that postulated blue sunrises and sunsets on Mars, complete with the reasons why.  At the time, I thought of that is the speculation of an author who probably wasn't all that well-informed about science.  There was plenty of that (and still is) in science fiction, but there were (and are) also plenty of authors who actually do have a good science background, or who are scientists.  Isaac Asimov is the canonical example of the latter, and he also wrote several hundred non-fiction books to popularize science...

Paradise perambulations...

Paradise perambulations...  Yesterday afternoon we had sunshine with a few clouds in the sky; temperature was a beautiful 63° and the roads and pastures had dried out a bit.  All three dogs, Debbie and I took a walk of a mile or so up the dirt road that goes east from our home.  The views back to the west from the top were so nice – the lush greens of spring in farmland dominating.

Earlier in the day we had taken a drive up to Porcupine Reservoir, about 7 miles south of our home.  We wanted to see if the recent rains had raised its level, and they had.  But we also were treated to some other sights.  Flowers, especially lilacs and tulips, abounded in the yards of almost every home we passed.  Nearly all deciduous trees are now in leaf, and the sticks of winter are largely shrouded.

But the real treat was birds – lots and lots of birds!  Probably the most fun for me was sighting several common loons on the reservoir.  I knew they were present here in northern Utah, but I had no idea they were here in such number, or on Porcupine Reservoir.  That's very close to our home!  Also spotted on the reservoir: a new bird for me, the double-crested cormorant (at right, not my photo).  Away from the reservoir, we also spotted a single male lazuli bunting, a male American goldfinch, and several yellow warblers (most likely Wilson's, but we didn't get a good enough view for a positive ID).  Very nice!
