The seasons of Saturn... As imaged by the Cassini probe. Via APOD, of course. Full resolution version here.
Not long ago, I was talking with one of our local kids about the robotic probes that captured the wonderful images like these. She had never known a time when high quality imagery of objects in space was unavailable. Somewhere during the conversation, it dawned on her that the robotic probes were a relatively recent invention, and she asked me how we got images “before”. When I told her that we simply didn't have them – that, for example, we knew Saturn as a fuzzy blob with fuzzy rings and very little detail – she thought I was pulling her leg. Yet I can easily remember the wonder of those first probes – Ranger, Mariner, Venera – returning grainy images that were miraculously better than what could be obtained from earth. I can also remember the amazing advances in adaptive optics making leaps and bounds in improving earth-bound astrophotography. It wasn't so very long ago, really, that images like the one above could be found only in science fiction illustrations made by painters with vivid imaginations. Now they're routine, and rather taken for granted...

Morning in Paradise...
Morning in Paradise... I woke up at 3:30 this morning, and I could tell that I wasn't going to be able to go back to sleep. So I got up, took a shower, and then walked outside with Mo'i. The sky was moonless and slightly overcast, so it was dark but I couldn't really see the stars very well. The night was
quiet except for a few birds peeping occasionally, and the sounds of hundreds upon hundreds of sprinkler heads irrigating the fields all around us. These sprinkler heads come in all manner of shapes and sizes, from the bog-standard Rainbird impact sprinkler at right to the monster “guns” like the one at left, with nozzles as large as 1" in diameter. Not only does each model of sprinkler have its own unique sound, but various accessories also do. For instance, many sprinklers alongside a road have “shields” that stop the sprinkler from spraying the road; these have a very noticeable sibilant sound. Then there are many sprinklers that have the ability to reverse direction, so they sweep back-and-forth over an area; these make different sounds depending on which direction they're rotating.
The most complex sounds of all come from some of the big guns that have computers controlling the water pattern so that it makes even coverage over a rectangular field. The computer moves several controls on the gun to make the water shoot exactly the right distance to hit the corners of a field without over-spraying the sides. They even compensate for wind drift! A few weeks ago, I stopped to talk with a farmer setting one of these up. He looked like an IT guy, with a laptop plugged into his “gun”, a wind direction and speed sensor, and a GPS surveying system to plot out the fields geometry. He told me that his “gun” cost a little over $3,000, but would pay for itself in the first year by evenly sprinkling his whole field without over-spraying. He figures he'll save around $1,000 in fuel alone (the sprinkler is powered by a diesel pump).
I could hear all these sprinklers as we walked. Some of the sprinklers I heard were likely over a mile away. It's quiet at 4 am in Paradise :)
Today is mowing day. I haven't mowed for over a week, and I irrigated this week. The fertilizer I put down a few weeks ago has kicked in, and the warm sunny days have done their thing. My lawn will have to be reclassified as a forest if I don't mow it down soon. I'm going to generate enough clippings that you'd think I could bale it and sell it as hay :)
Usually when I finish mowing, our driveway is covered with lots and lots of grass clippings. Today I'm going to blow them all off with the wheeled blower I got last week. Should look very nice when I get done!

Progress in Paradise...
Progress in Paradise... Did you ever have one of those projects that you thought was going to be a trivial thing turn into the project from hell? That happened to me today. The project? Installing drip irrigation for the five pots of color that we have on our second floor balcony. What inspired me to do this was discovering a spigot immediately below the balcony. No particular part of this project was hard – the only real problem was that I kept forgetting one part or another for the system. Since this was the first drip irrigation I've installed at our home in Paradise, I didn't have the box of all the miscellaneous parts and tools you need for this job. There's the filter, the faucet adapter, the pressure reducer, the back-flow preventer, the timer, the 1/2" tubing, the 1/4" tubing, the barbed flow emitters, the bug stoppers, the stakes, the emitter installation tool, and 25 or so other things. I made a lot of trips to Ridley's. Had to fill up on gas. I'm thinking about new tires. And I definitely am now overdue for maintenance on my truck. My wallet is overstuffed with Ridley's receipts, most of them for under $5. Sheesh.
Well, now I have that box of miscellaneous drip irrigation parts and tools!
And the drip irrigation is working fine.
I also finished installing three swinging bird feeder arms on our balcony. I started the installation a couple days ago, with that effort ending with a couple coats of black paint. Now that the paint was dry, I could install the actual arm and hang some feeders out: two hummingbird feeders and one oriole feeder. We've seen quite a few of both around here, including a nesting pair of Bullock's Orioles near the southeast corner of our property, in a black willow along the irrigation canal. I like these swinging arms, though I wish they were made of a bit heavier gauge steel. Still, they're strong, mounted easily to the balcony rail columns, and the swinging action is perfect for getting the feeders out over the yard (instead of the nice, clean balcony floor). The hardware that comes with them assumes you're mounting them to wooden beams, but all I had to do to make them work was to buy some good sheet metal screws and an “L” bracket to hold up the bottom. This was both inexpensive and easy. The black paint was a choice of mine, to make the swinging arms match (and blend in with) the balcony railing. That worked great!
The dogs and I just got back from a roughly one mile walk, which we made very slowly because it's hot outside. Our thermometer reads 90°, and I believe it. The weather site says it's 23% relative humidity right now – not bad. Except that I know that's wrong, because we have irrigation running upwind of us – it's probably more like 80% at our house. When we had walked about a quarter mile away, the humidity dropped sharply; the difference was easily perceptible. The dogs had one exciting moment along the walk today. They all stayed on leash, but at one point they all three (even the ancient and venerable Mo'i!) zeroed in on a dead robin about 4 feet off the road. Suddenly I had three dogs pulling me with about 500 pounds of force. It was simply not possible for me to hold them back – until it occurred to me to grab onto my neighbor's fence post. For a good minute or so, those damned dogs did their level best to separate my left arm (holding their leashes) from my body. If they could have mustered just a few more pounds of force, they'd have succeeded. When I hold my two arms straight out in front of me now, my left arm is now about a half inch longer than the right. If it's still that way in the morning, I'm going to be a little worried about it!

Progress in Paradise...
Progress in Paradise... Debbie's still getting a little better each day. Her appetite (which has been suppressed by the pain meds) is starting to kick back in. We had pizza yesterday afternoon, which is by far the most substantial food she's had in two weeks. Swelling and bruising is slowly getting better, but not fast enough for her :)
Yesterday morning a gaggle of neighbors (Tim D., Maria S., and a bunch of little S.'s) came out, and we all pulled mustard from our field. Tim is running alfalfa and barley on our field, and one section – about a half acre – is more mustard than crop. There's no way to get rid of that other than pulling it, all 10 bazillion plants. We worked on that for a couple of hours yesterday, and about three hours this morning, and now its about 75% gone. We've made giant piles of the pulled mustard, which we'll be hauling up to an old quarry a half mile away, to dry and be burned. Monday morning we'll finish up the last of it. Pulling mustard is pretty low on my list of fun things to do, but ... doing it in a group like this, in soil softened by irrigation, with lots of joshing and good conversation ... that makes it a lot more interesting. I walked back in this morning with a stiff back, a serious thirst, and a big smile. I'd do it again in a heartbeat.
Yesterday morning, right after we finished pulling mustard, Ryan O. (our heating and air conditioning guy) showed up to reconnect our air conditioning compressor. He had disconnected it last fall for us, so that I could dig a trench under it for water, network, and gas connections to the shed. When he lit it off, there was the most lovely burst of cool, crisp air on our second floor. It's been sweltering up there with our outdoor temperatures in the high 80s and low 90s. Now it's just sitting there at 72°, and feeling ever so nice when I come in from outside. Yay Ryan!
Not long after Ryan left, my new brush mower showed up. This is a 20 HP beast that will chop through 6' tall brush and 2" diameter saplings. I hook it to my ATV, which gives me a combo that I can get into just about anywhere. The thing was a kit, naturally. It took me about 3 hours to uncrate it, assemble it, fill it with oil and gas, and light it off. The engine is electric start, and the thing lit off the very first time I cranked it.
There's a lot about a quarter mile north of our place that just sold early this year. The new owners haven't built on it yet, so it's just two and a half acres of weeds. Those weeds were taller than me – 6 or 7 feet tall in places – and some of them had 1" “trunks”. I called the new owners and got permission to mow it down, and that's what I used to test out my new mower. It worked like a champ! I only managed to stall the mower once, in a particularly tall thicket of something that looks a bit like tumbleweeds. The rest of it all went down effortlessly. It was hot, dusty work, but otherwise not physically demanding. Ninety minutes and the field was down. Yay!
I'm not sure what I'm going to do today. For now, I'm just going to sit and enjoy my apple juice and chair :)

Debbie update...
Debbie update... Well, we're back – and with unexpected news. Good news, mainly.
When we checked in for her appointment, we were surprised by a request to take more X-rays. This request came before we'd even finished the check-in paperwork. Though we'd brought our iPads so we could read while waiting, we never even got a chance to crack them open. The MRI from last week was full of artifacts from the metal in Debbie's knee (we knew this already), so the surgeon wanted X-rays to get a good picture of her knee's current status. These X-rays went quickly and easily, in no small part because of the kind and attentive work of the X-ray tech, a young lady named Brook.
As soon as we were done with the X-rays, we were scooted into the exam room, where we waited for about 10 seconds for the surgeon (Dr. Tom Higginbotham) to come in. We'd not met him before, so we didn't know what to expect, though he was highly recommended to us by two friends in Paradise. Within a few minutes, we knew we had a good 'un – he was cheerful, considerate of Debbie, full of information, and happily answered all our questions.
But what he had to say quite surprised us! While he acknowledged that the MRI shows a “slightly ratty” meniscus, he's not at all sure that's a problem. And, more importantly, it's not the worst problem in her knee. He said that the MRI also shows a fracture of her medial condyle (the knobby “knuckle” of the knee, one of two attached to each femur, or upper leg bone). The fracture was just a hairline crack, and the X-rays confirmed that there was no displacement (bones shifting) at all. The treatment for this is very simple: wait. Wait for about six weeks post-injury, or about four weeks from now, before putting any weight on that leg. No surgery required.
The way this fracture was diagnosed was interesting. The MRI clearly shows the edema in her knee. “Edema” is just a fancy word for swelling, in this case in her knee. It was very evident indeed at the time the MRI was taken, and indeed it still is. The MRI also shows that there were two kinds of liquid causing the edema. One was liquid that was mostly water, but the other was a liquid that was mostly fat or oil, and it floated on top of the water (much like separated salad dressing). The water-based liquid is mainly from blood or plasma, but what's the fatty liquid from? Well, it turns out that the presence of such a fatty liquid is a signature of a fracture. It's caused by bone marrow leaking out of the broken bone. It was the presence of that fatty liquid that lead Dr. Higginbotham to search for the fracture, which was quite a subtle feature on the MRI (and didn't show up at all on the X-ray).
So now we have a follow-up appointment in mid-July, and between now and then she's going to be basically bedridden and helplessly dependent on me. Which she hates, of course. After she's all healed from this fracture, then we'll have another discussion with Dr. Higginbotham about whether to clean up that meniscus (and remove all the hardware)...

It's almost like they understand the value of standards :) Even Microsoft is participating, which makes me wonder if the end days are nigh. In any case, if this standard is actually widely deployed, it means that soon the browser environment will not be strictly a JavaScript world – any programming language could be supported in a cross-browser way. Watch out, operating systems! Browsers will be the new applications platform...

Progress in Paradise...
Progress in Paradise... Today's the big day for Debbie. We're off to see the surgeon today; it's the evaluation for her torn meniscus repair surgery.
I went walking with the dogs early this morning. Our routine walk (past the barley field at right) turned into something very non-routine, though, when Race decided to take off chasing voles through a just-mowed alfalfa field. He ran about a mile north of me; I could hardly even make him out. I tied Mo'i and Miki to a fence post and took off after Race. Only by jogging about 3/4 of a mile could I get close enough for him to hear me, and even then he was reluctant to come to me. I finally wrassled him into a leash – which is where he's going to stay. Forever.
Our neighbor's 11 year old boy (Nicolas S.) and I helped our mutual neighbor Tim D. move his irrigation pipes this morning. The pressure has been low for a couple days, but this morning it's back up, so Tim was eager to get his four strings of pipe up and running on his alfalfa. He's also wetting down some mustard so that Nicolas and his siblings can pull it out later today.
Yesterday afternoon we took delivery of some carpet stair treads. They're quite nicely made, and Debbie is very happy with the color and design. I'll be installing them today and tomorrow...

Progress in Paradise...
Progress in Paradise... Debbie's still on the mend. Tomorrow's the big day: surgical evaluation.
I started my day with a walk, at about 5 am, with all three dogs (some photos below). The weather was lovely, and we all watched the rising sun playing on the hills across the valley, to the west. Race was bounding through the tall alfalfa like a mad dog – in the space of five minutes, I'm sure he traveled at least two miles. At one point he was a half mile or so away from me. All I could see was the madly waving white tip of his tail, except for when he made a great leap onto a (possibly imaginary) vole. He did this about every ten seconds. He's going to be very disappointed on our next walk, though – the alfalfa field was mowed today. They'll probably bale it on Friday, then start watering to start the next cutting off growing quickly...
I had a good day today; got a lot done. I started by making a long-overdue cleanup of the shed's first floor. I loaded the tractor's forklift up three times: once with plastic and other packing trash, again with cardboard and pallets, and finally with two giant trash containers. You can actually see the floor in the garage section now :) Then I installed three swinging hummingbird feeder holders on our balcony rail. This, of course, involved several trips to the hardware store for screws, paint, etc. But it's done now!
Toward the end of the day my Billy Goat blower arrived (mine is similar to the one pictured at right). I had to meet the truck in Providence (about 8 miles away) and we transferred the 165 pound box to my pickup. Naturally it was a kit, and it took me about an hour to assemble it. The Honda motor started on the third pull (after being shipped without either gas or oil) and roared to life with no hassles at all. My test run down the driveway was a spectacular success – one pass each way and every last foreign object is blown off the pavement. Awesome! I never knew such a device existed until the crew came to seal my driveway two weeks ago. They used one of these to clean my driveway before spraying the sealant. After watching them work with theirs, I said “I gotta get me one of those!” So I did :)
Now I've got some laundry going, and I'm about to go wash the dishes, tend the cats, walk the dogs, and then crash. Hard!

Progress in Paradise...
Progress in Paradise... Debbie continues to improve every day, though that dang knee still can't hold any weight. Just two days until her surgical evaluation. She's backed way off on the pain medication, which I'll take as a very good sign!
Lots of little things got done the past couple of days. I finished mounting my shaper to its mobile base. This was a little complicated by the fact that I needed to raise it a couple inches. I used 4 x 6 lumber, resawn (on the band saw) down to an actual 2" x 5.25". I cut it to the right length and mounted it in the bottom of the mobile base, and the shaper is attached to the wood from the top. Works great! Then I assembled and tested my new log splitter; it worked just fine.
I've been waiting for several months now for a ballast box to go on the three point hitch of my tractor. This counterbalances a load in the front loader when I don't have the backhoe attached. My workaround was to leave the backhoe attached all the time :) Yesterday evening Lawrence W. from Agri-Service delivered it, finally. It's basically just a big steel box with the right bits on it to mount onto my tractor's three point hitch. I fill it with something heavy (dirt or stones will do fine) and I'm good to go. I'll be taking the backhoe off shortly to test this out.
I've set up all the 3" aluminum hand line in our yard now, so we're ready for the irrigation season. We have two lines, with 12 and 7 sprinklers respectively. Today I bought three more sprinklers and risers so that I can extend that to 14 and 8 sprinklers. This is so that I can irrigate two areas that we're converting from weed patch to lawn. Naturally, just as I finished all this setup our Paradise Irrigation pressurized water lost all pressure. I suspect a filter is clogged badly somewhere...
This morning I walked the dogs before dawn, at about 5 am with the sky just beginning to lighten in the east. It was a crisp, cool morning and the dogs all reveled in it. Miki and Race bounded through the alfalfa, which is now about 3' tall. I'm sure they'll be mowing it very soon now, as it's in full bloom.
My neighbor Tim D. came over around 7 am to move his three strings of hand line. I gave him a hand (as he's done for me many times), and we had a fun conversation the whole time we were working. Neighbors driving or walking by stopped to say hello and shoot the breeze for a few minutes. We found a tequila bottle out in our field (where Tim is running alfalfa), and we both marveled at the unlikeliness of that artifact showing up there! I noted on one of his hand line strings, Tim has a 15' long section of 3" hose (allowing him to bend at any angle) that was old and full of holes. I picked up a new piece today and replaced it. Fitting that new hose up would be hard for him, as he's got pretty bad arthritis in his hands. It felt good to be able to help a bit. I haven't told him what I've done (and he doesn't know about this blog), so I'm anticipating him trying to figure out how his old hose magically got renewed :)
Yesterday I heard from LeGrand Johnson company that they're going to have a big loader out our way next Tuesday, and that I can have some of its time. I'm going to get them to do some cut-and-fill work on the southeast corner of our property, between the irrigation canal and the highway. There's a section of old irrigation canal there. I'm going to have them fill that in and make a gentler, consistent slope in that whole area. The goal is to get a slope that I can mow easily. Once I have the right slope, I'll start spraying it a few times a year with 2,4-D, and pretty soon I'll have grass there.
Now I'm trying to get myself motivated to clean up the shed. It's full of packing material and dirt that need to be dealt with. But it's hot and I'm feeling lazy :)

Paradise people...
Paradise people... This is one of those days when we can't help but think we're actually living in paradise...
First, this morning I was out moving some irrigation pipes (a routine thing out here). My neighbor Tim D. put-putted up on his ATV, hops off, and starts helping me move the pipes. He'd spotted me from his place, a half mile away, and decided that I needed help. I could easily have done it myself (and did so quite a few times last year), but the job was much more pleasant with a friend helping out.
Second, Michelle H. came today to clean our house. She's been coming every two weeks since January, and we've come to think of her as a friend. Always cheerful, her daughter Lizzie often helping, and the house looks great when she's done. Our dogs love her (an important measure for us :). This morning when she drove in, I warned her that Debbie had fallen and hurt herself, and talked with her about what we needed done. An hour or so later, Lizzie rang the doorbell – and she had a beautiful bouquet of flowers for Debbie in her hands. I got her a vase and she fixed them all up; now they're at Debbie's bedside.
When we were looking at houses up here, we were looking at the properties and the homes to evaluate them. I did go interview all the neighbors to make sure we weren't going to move next to some raving lunatic, but we weren't consciously using the quality of our neighbors as a selection criterion. Now that we're here, we think we screwed up: we should have found these Paradise people first, then moved into whatever hovel would allow us to be near them. Instead we accidentally bought a nice property right in the middle of a whole bunch of the nicest people we've ever met. The “provincial Mormons”, as one of my friends called them (a Mormon himself!). He was gently poking a little fun at them, but I think they should wear that label as a badge of honor...

The crazy things progressives believe...
The crazy things progressives believe... I heard this on NPR (I listen so you don't have to) while on the road to get some tractor parts. I needed hydraulic couplers for my new log splitter, and I listened to the Diane Rehm show on the way up.
I wasn't on long enough to catch the name of her guest, but I did hear him expound on a notion I'd not heard before. From Ms. Rehm's responses, I could tell this was something she thought of as obviously true. The notion: that competition and altruism were in direct opposition. In other words, that one could not behave in an altruistic manner and still succeed in a competitive environment.
I'd never heard this notion stated baldly like this before. The ultimate altruistic society would be socialist (or Communist), in the theoretical sense – not how any socialist or Communist state as actually been implemented. In such states, there would be no competition. All that is old hat, standard progressive fare. What's new to me here is the assertion that competition must be eliminated in order to have altruistic behavior.
Ms. Rehm's guest expounded on this at some length. He believes, for example, that children should be shielded from competitive pressures – and then they would “naturally” grow up to exhibit altruistic behavior. In other words, perfect little socialists.
This notion is also a wonderful way to demonize capitalists. If you're a capitalist, you are by definition competitive – and therefore you're a selfish oaf and the enemy of the perfect altruistic state.
These sorts of things leave me speechless. I cannot imagine the profound naivete and self-ignorance required to actually believe such utter balderdash.
And these people vote. And they'll likely vote for either Hillary or Bernie. And these thoughts make me feel the doom is approaching...

Quote of the day...
Quote of the day... From Glenn Reynolds, aka Instapundit:
If I were Romney, I’d run for President again, with bumper stickers that just say “I fucking told you so!”Oh, yes...
A morning in Paradise...
A morning in Paradise... Debbie's getting stronger, and having less pain, every day. This morning she looks like she could get up and go for a walk. I think it's only the meniscus tear stopping her, and that should get fixed in the next week or so...
My job for this morning was to set up the irrigation for the strip of lawn along the east side of our property. This is about three weeks later than last year, as we've had so much rain the past month. But it's time now! The pipes have been stacked on the ground for the past 8 months, so they're full of dirt, leaves, and dead voles. After I laid all the pipe out, I left the end plug off and blasted water through the pipes to clean them out. Then I put the plug in, turned on the water, and discovered that I had four plugged sprinklers (out of 12). Not too bad. Fixed them, but then discovered that the last pipe's gasket was gone, so tons of water was leaking around the end plug. Turned off the water, put in a new gasket, turned the water back on, and voila! We've got irrigation (photo at right, click to embiggen)! I'll be using this roughly weekly for the next four months or so.
At the end of this exercise, I was soaking wet from unplugging the sprinkler heads. To get dry, I rode my ATV up and back a farm road near our house, the same one we go walking on – except I took the road all the way to its end. I discovered that we've been walking on the worst part of the entire road! As soon as Debbie's good to go walking again, we're going to change that. The last 3/4 of a mile of that road are a gorgeous walk through rolling fields, right now planted in a grain I don't recognize and alfalfa. The alfalfa is in bloom; looks like the farmer's late in cutting it. The last part of the road (middle photo) is overgrown with alfalfa, but still easily passable. Along the way I saw two pairs of quail, a species I don't know with prominently rusty brown coloration. No chicks, dang it! I also got a closeup view of a meadowlark, plus I flushed a red fox out of that alfalfa field. I think he was hunting voles :)

It's lovely...
It's lovely ... when one gets a good night's sleep, isn't it? And it's a lovely morning here in Paradise. People all around me are setting up their irrigation lines for the first time this year, and that's exactly what I'll be doing in just a little while myself...
Yes...

Paradise blossoms...
Paradise blossoms... These are all from our yard, today and yesterday. The most surprising ones to me are the wild roses, 25 feet in the air, blooming after climbing our choke cherries (last photo)...
Skyrmion memory?
Skyrmion memory? I know very little about skyrmions; just what I've gleaned from a few articles read over the past year. I can't help but think of magnetic bubbles (which were also used for computer memories) when I read about them, though they're not at all the same thing. This morning I read of some recent advances with skyrmions, including some potential mechanisms to use them for computer memory.

Progress in Paradise...
Progress in Paradise... Debbie is starting to back off on the pain medication. This took a lot longer than either of us expected, but we're taking that as meaning she's on the mend. She's got nearly full use of her right (injured) arm back, and all the swelling at various places in it is nearly gone. She's got a lot of bruising, though, and it continues to “evolve” daily. Her injured knee is still too painful to bend at all – almost certainly the meniscus tear – and she still can't put any weight on it at all. Today we're going to try to get her in the shower, for the first time in 9 days. We're both looking forward to that :)
Yesterday I kept busy with little things. First thing in the morning, while it was still cool, I leveled a few square yards of soil near the house, where we trenched last year to get water, gas, and network to the shed. This is the area where our air conditioner's compressor is mounted, and it's getting warm enough that we would like to have that working again. After leveling, I set four 18" square pavers in place to make a square yard base for the compressor. Then I set the compressor itself on top of the pavers. Early next week our HVAC guy (another of the wonderful contractors I found last year) will be here to reconnect it all, and recharge the refrigerant.
After I finished with that, I tackled a window screen and screen door in our bedroom. These both had falling-apart screen material in them, not at all cat-proof (and Jahar, our Savannah cat, lives in our bedroom). I replaced all that with pet-proof screen, plus installed new wheels in the screen door. This took a trip to Home Depot, of course. If there was anything that I wished was closer to us, it would be Home Depot :)
Just after lunch, a truck driver (with a comically stereotypical Mexican accent) called to warn me he was about to arrive. He was delivering my new log splitter – a 30 ton model that attaches to my tractor's 3 point hitch, and (more importantly) uses the tractor's hydraulics. The thing weighs 550 pounds, so we needed my tractor's fork lift to get it out of the truck. We had another little challenge first, though. The log splitter was laying sideways on a double-sized pallet, twice as long as it was wide. It was sitting cross-wise in his truck. Between the log splitter and the trailer's door was another pallet (not mine) with 1,500 pounds of paper products on it. The driver wanted me to offload that pallet that was in the way so he could roll my pallet to the back. My tractor can't lift quite 1,500 pounds, though – it's limit is 1,250. We tried, but it wouldn't budge. The driver thought we were stuck until I pointed out that we could rotate my pallet (so it was oriented long ways), then move the little pallet alongside and behind it with his pallet jack. It took me some talking before he got the idea, then he was smacking himself in the head for missing something so obvious. The scene was like something out of an implausible Hollywood comedy. Once we maneuvered the little pallet out of the way, offloading mine was a breeze – and now yet another project sits in my barn. Why is this another project? Well, because of course it's a kit – and in addition, I have to get custom hydraulic hoses made up to fit my tractor. Of course.
All you equipment manufacturers out there: it wouldn't offend me at all if you were to deliver the stuff I buy ready to use. Not one bit...

Next time you consider letting a kid touch you ... remember the photo at right. That's the result of culturing the bacteria and fungus found on a kid's hand (an 8 year old boy who had been playing outside). Seriously.
I don't actually know if the result of culturing the hand print of an adult would be any better. But I'd prefer to think so :)

Philae found?
Philae found? Maybe. Excellent summary of the search, and the “candidate” for Philae seen in the second and third photos at right (all three photos are of the same area; click to embiggen)...
Excellent book!
Excellent book! Just finished The Martian, by Andy Weir, last night. It's like the love child of Heinlein and a nerdette. The science and technology are all plausible. The central character in the book chews his way through a seemingly never-ending series of existential threats, using nothing but the material at hands, his will, and a not-insignificant amount of pure American-style cleverness. I couldn't put it down!
I hope that Andy is working on another book...

Debbie update...
Debbie update... We just heard back from her orthopedist after he had a chance to review her knee MRI. There's a clear diagnosis: a posterior horn medial meniscus tear. The orthopedist unequivocally recommended surgery for her tear (they vary quite a bit). We're in the process of getting that set up right now.
This is actually a bit of a relief for us. The meniscus tear, in the grand scheme of things, is far from the worst sorts of injury that can happen to a knee. Debbie's already experienced one of the worst: a tibial plateau fracture, and a bad one at that. Generally surgery to repair meniscus tears is arthroscopic, low risk, and fast recovery. We're hoping that hers will fall into that category.
Also, there's quite likely a bit of a bonus for Debbie in this surgery. When she had her tibial plateau fracture surgery (two and a half years ago), the surgeon “installed” a significant quantity of very expensive hardware – a fancy plate and a half dozen or so titanium screws. She could never bring herself to schedule a surgery just to remove that hardware, so she's been clanking around with it (well, it doesn't really clank) ever since. We're going to see if it can be removed at the same time the meniscus repair is done.
Phone just rang, and she has an appointment with a knee specialist next Thursday...

Precipitation in Paradise...
Precipitation in Paradise... We had a surprise thunderstorm last night. The forecast was for overcast, but we got a bit more than that – four tenths of an inch more, to be precise! Our backyard is now once again a mud bowl, and it will take a few days to dry out. Meanwhile, we have more rain actually forecast for this afternoon.
A couple of months ago, the locals with long experience here were worried about a drought. Now they're worried about their hay rotting in the sopping fields. Crop dusters (both fixed wing and helicopter) are having a boom time here, as many fields are too wet for a tractor spraying rig to traverse them. I also saw a fantastical machine the other day (too far away to get a photo): a spraying machine with around a 100' wide spray boom, all running on the sort of giant balloon tires you see on dune buggies, but scaled way up. Those tires spread the weight of the rig over quite a large ground area, and he wasn't sinking into the muck at all. The photo at right will give you the general idea, but the one I saw was much larger...

Visual perspectives...
There's something similar that I hope to do in my retirement: capture natural sounds that we cannot hear because they are too low or too high in frequency, or their modulation is too low or too high in frequency. I'd also like to develop a phase-array microphone that will let me accurately point a camera at the source of a sound (especially for birds). Way back in the early '80s I briefly played around with these notions, but the compute power available then made it impractical. Today the compute power in my iPhone is more than adequate! Digital audio capture and electronic phase delay has also gotten much easier and cheaper than it used to be. I think the most challenging aspect of these projects today will be the digital signal processing (software), not the hardware...

Yet another way to choose where to retire...
Yet another way to choose where to retire... I didn't have this information when we chose Cache County, Utah – but it's nice to have the affirmation anyway. The map shows UFO sightings per capita, and Cache County basically doesn't have any. I read that as the population here being a bit more grounded than in many other places.

“I say we should ban cows and human farting.”
“I say we should ban cows and human farting.” So says friend and former colleague Simon M. in his sarcastic reaction to the news about the EPA proposing to regulate methane, carbon dioxide, and other “climate change inducing” chemicals from commercial airliners.
His comment relates to the fact that cow farts and human farts are also sources of methane, and therefore potentially subject to EPA regulation as well. Mandated Beano, anyone? I suspect my wife would approve :)
Aircraft engines produce (primarily) nitrogen, water vapor, and carbon dioxide as exhaust gas components. There isn't much room to make the engines more efficient, as commercial pressure from high fuel prices has done wonders there already. Nitrogen isn't a concern with respect to climate change. Carbon dioxide is the main thing the EPA is proposing to regulate. The EPA does not propose regulating water vapor emissions, despite the fact that water vapor is dozens of times more potent a greenhouse gas than carbon dioxide is.
So lets think about this for a moment. The EPA tells commercial aircraft manufacturers that they must reduce the carbon dioxide emissions. What mechanisms do the manufacturers have available to them? The most obvious one is to switch to fuels that have more of their energy in hydrogen, rather than carbon – which will have the effect of increasing water vapor emissions. Which, remember, are far worse for climate change than carbon dioxide is.
Now does this make sense in any universe? Sure it does! In the universe of the loony politicians!
The only other choices are to switch to exotic fuels that don't have carbon in them (very, very expensive), or to slow down the aircraft (because overall fuel consumption goes down non-linearly with speed, thus reducing emissions).
Shakespeare wrote (in Henry the Sixth) “The first thing we do, let's kill all the lawyers.” I think his priorities were slightly off – first should have been the environmentalist wackos, then the lawyers (which has the knock-on effect of getting most politicians as well)...

Paradise progress...
Paradise progress... Debbie's still doing fine. We've got a followup appointment with her orthopedist in two weeks, and we're both hoping that the level of pain and sensitivity has gone way down by then.
Today has been a day of chores and running around for me. Mostly little things, but I did get the screen replaced in the screen door of our kitchen. Replacement was necessitated by Race running straight through the old one to get outside, as though it wasn't even there. One second we had a nice, taut screen door; the next second the screen was flapping in the breeze and Race was a mere dot in the corner of the yard. Sigh. I ran to Home Depot, got some “pet proof” screen and an expanded metal grille for the bottom half of the door. I spent the best part of the day removing the screen door, cleaning out all the old screen (the rubber spline had become one with the frame), stretching and splining the new screen, installing the grille, and finally reinstalling the door. Every single step of the way something went wrong, of course. There was much Navy-learned language employed; the box elder bugs all ran away and the dogs were blushing.

Palliative care...
Palliative care ... is prescribed for the U.S.:
WASHINGTON—Saying there were no other options remaining and that continued intervention would only prolong the nation’s suffering, experts concluded Tuesday that the best course of action is to keep the United States as comfortable as possible until the end.It's one of those times where The Onion doesn't really seem like satire...
According to those familiar with its condition, the country’s long, painful decline over the past several decades has made it clear that the most compassionate choice at this juncture is to do whatever is possible to ensure America is at ease during its last moments.

I had conversations like this many times...
I had conversations like this many times... I once worked for a company named Stac Electronics. At one point the company hired a new CEO (J.T., for insiders). Read today's Dilbert strip:
This brought back instant memories, and for me, some laughter. That CEO – who was running a software company – had technical expertise that was over-matched by any randomly-selected decomposing aardvark. I was, at the time, the company's chief technical officer. After my first few attempts to have a meaningful conversation with him (my boss!) about anything I did, I gave up. Then I started entertaining myself at his expense, by trying to see just how nonsensical a conversation I could have without him picking up on it.
I never found the limit. He resigned (for other reasons) before he had any clue what I was doing...

Paradise Progress...
Paradise Progress... Debbie is doing just fine. She's not happy about being black-and-blue, or in pain, or not being able to even hobble around – but she's showing signs of improvement (pain is subsiding, she's eating better, and the swelling is going down all over). I'd post some photos of the black-and-blue, but I'm being threatened with all sorts of horrible punishments if I even think about that very hard. Tomorrow she goes in for an MRI of her knee. This is the same knee she broke over two years ago, and we want to make sure there's no cartilage or ligament damage.
Yesterday and today I made great progress repairing the damage to our back yard from all the hectic trenching we did last fall to get services (gas, water, electricity, network) to the shed. I've been holding off until the ground dried out enough for me to run the tractor over the back lawn without leaving deep ruts. I've been doing a lot of shovel work, using the forklift to replace concrete slabs back from where we'd removed them, and the loader to move small mountains of soil around to fill in trenches. Today I finished everything I can immediately do with the tractor. Tomorrow I'll start the finish leveling by hand, with shovel and rake. I'm guessing I've got two or three days of work on that, and then I'll be planting grass seed.
Now that the back yard has dried out, and isn't a giant bowl of mud, we're letting the dogs run around back there. They love it – an acre of nice green grass all to themselves!
I picked up my new glasses today. I can see again – hurray!

Just listen...
Just listen ... to this whiny, self-important little mind: Why I Defaulted on My Student Loans. The author is one Lee Siegel, best known for his sock-puppetry at The New Republic a few years back. This conspicuous moron:
This is what we get when we encourage a culture of entitlement – morons who believe they're entitled to have the rest of us pay for whatever they want.
I have no patience for that attitude, and I am not willingly going to pay for his chioces. Our student loan programs may be administered by idiots, and they are most definitely contributing to the high cost of college these days (especially when college is more about the amenities and the partying than the education), but still: it was his choice to partake. Lee Siegel and the others like him should have their student loan payments extracted from them by force if that's what it takes...
- Chose to go to colleges with expensive tuitions
- Chose to borrow the money to do so
- Willingly accepted the offered loan
This is what we get when we encourage a culture of entitlement – morons who believe they're entitled to have the rest of us pay for whatever they want.

New Horizons...
New Horizons... The NASA robotic explorer New Horizons is set to do a close flyby of the planet (or whatever they're calling it these days) Pluto. At it's closest approach, on July 14th, it will be just 7,800 miles from Pluto's surface.
How close is that? At it's closest approach to Earth, Pluto is almost 46 billion miles away. Aiming New Horizons to approach within just 7,800 miles is phenomenally good aiming. It's the equivalent of shooting a gun at a target a mile away, and deliberately missing the bulls-eye by exactly a tenth of an inch. NASA was able to make some course corrections along the way, but still ... that's mighty fine shooting!
New Horizons was launched in January 2006, over nine years ago. That's one very long voyage it's on. It's still in perfect condition, too – a testament to some excellent engineering and fabrication work. Surviving nine years in the harsh environment of space didn't happen by accident. The mission of the New Horizons explorer will continue for at least another year, exploring the Kuiper Belt for the first time. The mission team has identified several Kuiper Belt objects that they'd like to fly by, and if they get their extended mission (through about 2020) funded, they'll be able to do it. The funding required is far less than the launch of an ISS mission, but nevertheless it's at risk due to the priorities given (pretty much totally useless) manned spaceflight...

Innovations in education...
Innovations in education... These sorts of articles always leave me with a funny feeling, as they generally leave out the education method that's worked so well for me: self-education. It's not that I think there's no place for pedagogy – there clearly is. The vast majority of people I know both got their education in some sort of institutional setting, and expect that's where their education (and their kids') will come from. But I think there's a place for autodidacts as well.
Institutional education (i.e., schools) weren't completely useless for me, but they weren't far off. I was bored out of my skull in just about every classroom; the few exceptions provide the few good memories of my school experience that I have. Part of the problem was the slow pace, but the bigger problem was the shallow treatment of just about every subject. I was constantly wondering Why? Why? Why? in nearly every subject, and I wasn't getting answers from either the teachers (to whom I was an annoying pest) or the texts (which even then I could tell were glossing over huge areas of interesting knowledge).
On the other hand, the schools provided me with something I did need: access to textbooks (there was no Internet back then, so books were the only source of recorded knowledge), through the school libraries. Those books I absorbed on my own, almost entirely. Every once in a while I'd have a question I couldn't figure out, and a librarian (most often) or a teacher (occasionally) would answer it. All too often, though, what I got was an admonition to stick to material more suited to my age. For example, in high school I got very interested in understanding how semiconductors (the basis of transistors) worked – and when I asked my physics teacher about it, he advised me to wait until I was in college to investigate that. So I learned about semiconductors from a book checked out from the school library, instead – and what I wanted to understand was easily accessible by an interested high school student with a limited mathematics background.
Once I left high school, I continued my exploration of science and engineering on my own. I had my own motivations, even if I didn't understand them, and I didn't need a teacher to be able to learn the things I wanted to. That has been a lifelong habit of mine, continuing even now in my dotage.
This is the source of that funny feeling I mentioned at the start of this post. I've never quite been able to figure out why so many people seem to depend on institutional education. I'm convinced at this point, after having met quite a few others with the same point of view, that the answer has little to do with native intelligence (that mainly seems to affect the speed with which one learns) and much more to do with the motivation and will of the individual. There's something else as well, something to do with that expectation of institutional education. I've heard a great many people make the assumption that if they wanted to learn X, then they'd have to go to school (take a course, etc.) to do so. Relatively few people assume that they can learn X on their own. I have no idea why that's the case, because these days – especially with the information resources available for free on the Internet – there's very little in the way of obstacles impeding anyone from learning just about anything.
I have the sense that self-education is on the rise, though. It's definitely more respectable in the engineering world these days :) I think the Internet is making it more common, as well. I hope so...

Progress in Paradise...
Progress in Paradise... Debbie's doing fine. There were a few changes today. The most noticeable one: she developed a spectacular shiner (a black eye), with a dark blue/purple bruise extending nearly all the way around her eye. This afternoon that same part of her face swelled, but it has since gone back down. The pain and swelling in various other places is starting to recede. The pain medication she's taking is an excellent appetite suppressant, but I managed to find some food that she enjoyed: french fries and turkey salad from a place that's new to us. It's called “Juniper”, and it's located in downtown Logan. Our neighbor Tim D. recommended it to us for the soups (which I bought some of, but we haven't tried yet). I tried a halibut sandwich, and it was just plain delicious. The fish was perfectly done, and there was plenty of it – on a nice bun that tasted homemade, though there are enough great bakeries here that it could be store-bought. It's clear this is a place that we will return to.
In between other things today, I managed to get the lawn mowed. I also mowed down about an acre of weeds to the west of our house. Things are looking much neater around the homestead :)
I took the dogs for a walk in which we passed a neighbor's pasture that is currently the home to a couple of beautiful horses. The horses were interested in the dogs, and vice versa. Race got a good nose-rub in with the second of the horses in the photos below:
I've posted a couple photos of the robin chicks, in a low nest built in a half-dead tree in our front yard. Here's what they looked like today – they're outgrowing their puny nest:

D-Day...
Light blogging alert...
Light blogging alert... On Thursday evening I took our dogs for a short walk just before we planned to retire. When I came back in the house, Debbie was sitting on the bottom of the stairs, looking dazed and a bit confused. She'd fallen down the stairs just a minute or so earlier – she'd been walking down them in her stocking feet, and the slipped out from under her. I saw her hand swelling up rapidly, and she was feeling pain in her knee (the one she broke two years ago), head (which had a big bump), and hand. Time for the ER.
There we had the same general sort of experience we've had before with medical care here – all good. The people, in particular, were wonderful. The ER doctor on duty was the same fellow who saw Debbie after her fall in March. When we walked in, she was the only patient there – but soon afterward, the ER filled up, so naturally things got a little slower. We were there for a couple hours. They got her on pain medication quickly, then it was X-ray time. Lots of X-rays, from head to toe. The good news: nothing was broken. The bad news: lots of bruising, a broken vein in her hand (hence the swelling), and the pain in the knee (twice injured already) is worrisome. We've got an MRI scheduled for next Tuesday to get the knee checked out more thoroughly.
Meanwhile, Debbie is doped up and laid up. I'm taking care of all the things she normally does, plus helping her out as needed. She can't (yet) walk or get around on her own, so there's lots to do.
So blogging will be light...

71 years ago today...
71 years ago today ... the Allies invaded Normandy, marking the start of the extended invasion from the Nazi's west (the Soviets were already attacking from the Nazi's east). After much hard fighting, the Allies brought the Nazis to their knees, and the European front of WWII was over.
I've walked Omaha beach in Normandy, and visited quite a few sites of battles in WWII. I've also visited three Nazi concentration camps, and the ruins of Soviet fortifications in Estonia, and Nazi gun emplacements outside St. Petersburg (Leningrad). While I've read quite a bit of history (especially of WWII and the rise to power of the Nazis and the Meiji), but physically visiting the sites of the events I'd read about was more moving, more profound than reading alone could ever be. On the Pacific side, I've visited Hiroshima, Nagasaki, Okinawa, Tarawa, and Peleliu. My reading of history and those experiences have shaped me, especially politically. I wish more Americans could (and would) do the same...

Progress in Paradise...
Progress in Paradise... Debbie and I managed to get all the EVA foam laid down in her indoor agility court, on the west side of our shed. The first photo below shows the work in progress; the second shows the finished result. Installing this stuff was actually quite easy, though we had to learn some new tricks along the way. One unexpected challenge: the squares of foam are cut to metric size. Though they were sold as one yard square of 3/4" thick foam, they are actually one square meter (39.37" on a side) and 2 cm thick (which is slightly more than 3/4"). This made our layout just a tad more tricky than we'd first imagined, as of course our room is laid out in feet and inches. Oh, well :)
The EVA foam is pretty tough stuff. Cutting it with a knife, or possibly with big shears, looked like it would be a real pain in the patoot. So I did the obvious thing and looked it up on google: presto! A whole world of video tutorials, written descriptions, etc. The answer turned out to be straightforward: use a hot knife. Great. Where does one get a hot knife? Well it turns out I already had one, and didn't even know it! Last year I bought a Weller soldering gun, to do some heavy duty soldering. In the kit was a pair of hot knife bits. They can only cut about 1/4" deep, but three passes and I had it. It worked like a champ, especially when we figured out that Debbie could separate the cut while I wielded the (massive) soldering gun. I made one mistake while doing the whole floor, and we managed to re-use the square I messed up anyway.
While we were partway through this exercise, a crew from Statewide Paving showed up to “seal” our driveway. This isn't something I knew about until last year, when our neighbor Tim D. – a former paving supervisor – educated me about it. This is an area of business rife with shady operators and inferior products, so choosing the right product and contractor is important. These folks Tim had done business with before, and he knew that they did good work with the best product (a pure asphalt spray that contains no water).
The photos below show them at work on two of the three phases of the job. The first phase is simply cleaning off the driveway (no photo). They use a special wheeled blower with a 10 HP gas engine; it's powerful enough to blow fist-sized rocks right off the driveway. They also scrape any heaped-up soil or other junk off the pavement. This first phase is more than half the labor of the whole job. The second phase is filling in all the pits and cracks with a special thick asphalt (first photo below). Then, finally, they spray on the sealer (last photo). The guys were really good with a piece of plywood used as a shield to keep the spray off our lawn and plants.
Because our driveway had never been sealed before, they're going to put two coats on. The second coat goes on today.
So what does a sealer do, anyway? It makes the top surface of the pavement watertight, and (when done right) fills in all the little pits in the top surface. Both of these effects prevent water from infiltrating the pavement and then freezing in the winter (which would crack the pavement). Asphalt pavement, when first laid down, is a mixture of asphalt, gravel, and sand. It's not solid, though – in fact, it's rather porous. The sealer puts that waterproof layer on top...

Progress in Paradise...
Progress in Paradise... We drove up to Home Depot to get a few things we needed, and on the way up our neighbor (Tim D.) called us. It seems that a wandering driveway sealing guy was going house-to-house looking for customers. Tim is a retired paving supervisor for a large highway construction company; he knows this stuff inside and out. He'd used this guy in the past, and he'd done good work. Tim also knew that we were looking to get our driveway sealed, so he called us to make sure it was ok to sic this guy on our driveway. We said “Hell yes!” and while we were at Home Depot the fellow measured our driveway's area. He'll be back tomorrow morning to actually do the job: pressure-wash our driveway, then apply the sealer (hot pure asphalt, with no fillers of any kind). All for about 1/3 the price of a crappy sealing job (with no cleaning) in California. Sweet!
The imminent driveway sealing derailed me for the day, though – I had to run around like mad to move everything that was sitting on the pavement. That took a couple hours, and a lot of muscle work. But 'tis done!
Debbie, meanwhile, started actually installing the foam for the floor of her (soon-to-be) indoor agility court. As I write this, about half the foam is down, except for one skinny row near a wall. For that row, we've got to cut each “tile” before we lay it down. We do that with a hot knife: easy, but tedious and needing a steady hand. Another couple days and we'll have all that installed – and then there will be a couple of very happy dogs turned loose on this beautiful blue agility practice court!
