Shaper in Paradise... My shaper is the last big piece of woodworking equipment that I'm planning to buy, at least until I learn what else I need (a standalone sander of some type is a distinct possibility). I received the shaper last week, but other project have kept me from finishing the assembly of it until today.
The photos below give you an idea what it's like to unpack and assemble a piece of equipment like this. The first photo shows what it looked like when I took the top of the crate off: a nicely milled cast iron surface, covered with a thick layer of grease. The second photo shows it with the crate completely removed. All the parts that had to be assembled (dozens of them) were packed inside the green cabinet, as you can glimpse in the third photo. The fourth photo shows all those parts after I extracted them. The fifth and sixth photos show a couple of stages during the assembly process, which is nearly all on the top of the machine.
The last two photos should have a title: “Really, Grizzly?” The next-to-last photo shows the angle meter (for the tilting spindle). Looks great. Except – in the last photo, you see the handle for raising and lowering the spindle installed. It completely covers the angle meter. Really, Grizzly? That's the best you can do? Fortunately, I suppose, I don't expect to be changing the spindle angle all that frequently. But ... when I do, I'll be partially disassembling my shaper just so I can read the angle! Jeez. I certainly expected better for a machine in this price range.
Aside from that one awesomely stupid design element (really, Grizzly?), I like what I see here. The cast iron table is heavy and very nicely made, the sliding part slide true and smoothly, the tilting spindle works great, and everything on the machine looks like it was built to withstand a nuclear assault. I haven't wired it up yet, so I haven't been able to actually run some wood through it.
While I've got the shaper itself completely assembled, I haven't yet assembled the rolling base I bought for it. That's a project for another day, along with wiring it up and lighting it off...
Really, Grizzly? Really?

Storm in Paradise...
Storm in Paradise... Yesterday afternoon we had a brief visit from the storm king. It brought very little rain (just 0.04"), but lots and lots of drama – mainly in the form of gusty wind and dark, evil-looking clouds. It was all over in less than an hour...
Progress in Paradise...
Progress in Paradise... Yesterday I went to Seeholzer Vision in Logan and had my eyeballs examined. I'd been there once before, last year, to get a pair of glasses repaired. This time I needed an exam, plus I needed new glasses to replace the ones I melted last week while tending the bonfire.
Dr. Seeholzer is a second-generation optometrist – his dad started the practice over 60 years ago. I thoroughly enjoyed the visit, which isn't at all what I expected! Dr. Seeholzer (who asked to be called “Jeff”) is an affable fellow, happy to answer my questions in any amount of detail I wanted. His exam was thorough, as was his review of my optometric history (which, unfortunately, he thought was interesting :).
I'm starting to think that appointments being honored on time is some kind of cultural norm here, just as in California it seem to be the norm for all appointment times to be basically ignored. My appointment yesterday was for 9:15 am, and I was ushered into the exam room (and the exam was started) at 9:13. Amazing!
This morning I hooked up my sprayer to the ATV, and sprayed ... just about every conceivable place on our property. I used 67% 2,4-D at 2.5 ounces per gallon (a 25% increase from last time), and sprayed our entire lawn, the field borders, the area between the irrigation canal and the highway, the non-lawn areas around our outbuildings, the dirt piles leftover from the shed construction, and a bunch of weed “hot spots” scattered all over the place. I'd made two batches of spray, 40 gallons each, and all the spraying on our place used 72 gallons. The extra 8 gallons I sprayed on our neighbor's property (after getting permission, of course!), so they got a free second dosage on part of their yard. I ran out about a third of the way through their lawn :)
Debbie's been making great progress on recovering from her fall in March. Today she's feeling good enough to start cleaning up the agility court area of the shed, to get it ready for installing foam. She's been going on about half our walkies, too. It's great to see her getting better!

Mo'i in the moonlight, in Paradise...
Mo'i in the moonlight, in Paradise... Our ancient and venerable field spaniel (Mo'i) just keeps getting better. Beyond the Miracle of the Unnecessary Diapers, he's now getting physically stronger. There are increasingly frequent moments when he seems downright playful and frisky. Where he used to bark piteously at 2 or 3 am to be taken out for a walk (and to pee prodigiously), he now only occasionally barks to be let out before we wake up on our own.
That's what happened this morning. I awoke around 4 am, then read email and news for an hour or so before actually getting up. I took a leisurely shower, then wandered out to the kitchen to greet Mo'i. He was up, wagging his tail, and eager to get outside. We walked out into a wonderfully cool, still morning, brightly lit by the full moon that was about to set over the mountains to our west. He strained at the leash to go off and investigate all the things he could smell, and I could not. I smelled just four things: pines, spruce, roses, and the complex aroma of the irrigation canal. Mo'i ignored all those things and chased invisible trails of mice, muskrats, neighborhood cats, and who knows what else. He's reveling in the lush green grass of our lawn, something he rarely saw in Jamul. He was obviously having a good dogly time, tail wagging like mad. A couple of times, walking alongside me, he reached up and nibbled my fingers – something he did as a puppy when he was happy. The fact that he survived his cancer to make it up here, and can enjoy it, is a source of great satisfaction to Debbie and I...

TSA fails again...
TSA fails again... Several readers flagged this one for me. Larry E. also sent along a personal experience:
Most of the news stories about the current brouhaha don't mention it, but TSA (and its predecessors) have been failing these spot checks for years. In fact, they've never passed one! As Bruce Schneier likes to say, the TSA is all about security theater. It doesn't actually provide security, just the minimum necessary appearance (for sheeple pacification and political purposes) of it.
The continually failed security spot checks reminds me of a similar experience I had in the U.S. Navy. Hopefully they've gotten better by now, though I wouldn't bet any money on it. I served on a nuclear-powered ship that carried nuclear weapons, and it was a ship that could serve as “flag”, meaning that it could carry an admiral and his retinue – and had extensive secure communications facilities.
To give just one example of the security test we routinely failed (routinely as in every single time): one of the testing agents was always able to get into the radio room, right up to the teletypes and printers that were handling all the “secure” communications. The radio room could only be entered through a door that had a push-button combination lock (similar to the one at right), and the combination was frequently changed. How did the agent get in? It was trivially easy, as the combination was always taped to the door or frame somewhere easily visible. WTF? Why would they do that? Because the several dozen or so people who were cleared to enter the radio room (including yours truly) couldn't be relied on to memorize the new combinations. Plus distributing the new combination was an interesting challenge in itself. So someone always taped the combination up. I had access to the radio room for about three years (while I had responsibility for maintaining a computer involved in secure satellite communications), actually entered it hundreds of times, and I never once memorized the combination.
I went through screening one day and forgot some change in my pocket. I went through the body scanner and realized it, so I reached in my pocket to get it to show the screener but it was still in my fist as his device showed it, but he basically just wanded me over the pocket my change had been in and sent me on my way. I never had the chance to show him that I had it in my hand now and he didn't ask nor did he find it. Can you imagine is someone had even simple sleight-of-hand skills?I've had some personal experiences of my own over the years, mainly involving my pocket knife. I have a lifetime habit of carrying a small folding pocket knife with me at all times, and many is the time that I've forgotten to remove it (post-9/11) before flying. Only once was that pocket knife detected by airport security – and that was in London, getting ready to come back to the U.S. They confiscated it and mailed it to me (I paid the postage). I never counted the number of flights inside the U.S. where I took the knife through security, but it has to be in the range of four or five dozen times.

Why did nobody ever tell us?
Why did nobody ever tell us? This morning Debbie and I changed our bedclothes. Part of this effort included inserting a comforter into a duvet, something we've done about 10,000 times over the past 30+ years. While trying to find a corner in the duvet, I noticed a pair of cloth ribbons, about 8" long, sewn into the inside of the corner.
What could that be? A tie? To tie the corner of the comforter in place? Working on that theory, I checked inside of all four corners, and sure enough: there are ribbons in all of them. Who knew?
So then Debbie and I decided to try tying the corner of the comforter with the ties. We weren't quite sure how we were going to do that, but it sounded like it would make the clumsy process of inserting the comforter a bit easier. So we got the comforter in place, and then I went to tie the first corner – and discovered that the comforter had a handy loop right where we'd need it to make the tie work. In a jiffy we had the comforter tied into the right place, inside the duvet, and in fact that was much easier than the corner-holding and shaking we've been doing all these years.
Duvets come with insider corner ties? Comforters come with matching tie loops? We checked our other comforters and duvets. Yup. Ties and loops in all of them.
How the hell could we have been doing this for over three decades without once even suspecting that those ties and loops existed? And why are we completely surrounded by cruel people who never told us?

Snakes in Paradise...
Snakes in Paradise... There's one poisonous snake here, a particularly docile and low-toxicity rattlesnake called the Great Basin Rattlesnake. We haven't seen any of these yet, but we're not worried about them as they're amongst the least aggressive and lowest venom toxicity of all rattlesnakes – pretty much the opposite of what we were dealing with in Jamul, California. However, I have see four snakes here – all different, all small (about pencil diameter and 10" to 12" long). I haven't identified any of them, though one of them I'm pretty sure was a garter snake. One of these was on the shore of Porcupine Reservoir; the others in our yard, spotted while I was mowing. It's interesting that all last year, even with all the outdoors work I did, I never saw a snake. Now in the first few days outside this spring, I've already seen four.
Polygamy...
Polygamy ... a kind of “polyamory”. When I was a kid, lo these many decades ago, such things were to be found only in breathless tabloid articles and dry histories. Once in a while you might see a reference to contemporaneous polyamory in exotic foreign lands. Never would you run into it as a possibility in mainstream American society.
Things change. Faster than I'd ever have thought. What's the next frontier in permissiveness after polyamory? I'm guessing it will be the mainstreaming of bestiality, but I stand ready to be surprised...

Way back in about 1995...
Way back in about 1995 ... I worked for a company called Stac Electronics. My boss tasked me with designing an ecommerce-capable web infrastructure – a fairly advanced notion for the day. This was primarily an education problem for me, as when I started I knew almost nothing about the subject. One of the requirements my boss gave me was for redundant ISP connections, and I figured out pretty quickly that one could only do this, practically speaking, by connecting fairly close to the “backbone” and running a routing protocol called BGP. When I dug into BGP, I quickly ran into lots of discussions about security problems with BGP.
Twenty years later, nothing has changed.

Progress in Paradise...
Progress in Paradise... You may recall the Mormon horde that swept through our property two weeks ago, making massive brush piles from cleaned-up deadwood and brush, and ripping out almost a half mile of five-strand barbed wire fence. In the interim Debbie and I cleaned up and burned all the smaller brush, but a good-sized stack of larger wood remained. In between rainstorms last week, I sawed up about half of these logs. This morning, I sawed up the rest of them. The result is roughly a half cord of 18" logs. Some of these need splitting, but otherwise it's all good firewood.
About three-quarters of the logs were black willow. That wood burns hot and clean, but it's relatively soft. The rest is box elder (a kind of maple), and that wood is hard – so hard that cutting it up made the chainsaw blade smokin' hot, and required quite a bit of physical effort to get the blade to “bite” into the wood. There was one particular box elder log, about 20' long, that looks like it has been drying out for many years. I'm going to save the pieces of that one for turning on my lathe.
Now I'm back in the house, recovering from the (substantial) physical exertion of all that sawing. Plus, it's actually warm outside (about 80°), and that added to the physical impact. I'm about to help my recovery along by eating some beef stew that my lovely bride just finished cooking. As soon as she gets the gravy made, it's time to eat! After I recover from eating that meal, we'll go load up all that wood in my pickup, and then stack it in the shed. That's the last step to finishing up the work done two weeks ago by the Mormon horde...
Update (4:30 pm)... All the wood has been moved and stacked. It turned out to be more like 2/3 of a cord. With that plus the additional half cord or so that my neighbor is giving me, I should be nice and toasty in my office all winter!
The beef stew was delicious, by the way. You should have been here! There are some leftovers, but they'll be gone long before any of you can get here :)
After all the hard work today, we decided that we felt like ice cream floats. We just got back from a jaunt to Ridley's, where we got some Americana sodas and some Tillamook ice cream. They're in the deep freeze now, and in an hour or so we're gonna have us a good old fashioned ice cream float!
Update (6:30 pm)... Those ice cream floats (I had vanilla bean ice cream in black cherry soda) were every bit as good as we were hoping. Yum! Now for a walkie with the doggies, and we're off to bed. I suspect I'll sleep well tonight...

Robins in Paradise...
Robins in Paradise... While we were sipping our tea and coffee on our balcony this morning, we noticed a pair of robins were frequently flying into a mostly-dead tree in our front yard. This tree is on our project list to be replaced, but we won't be doing that for a while – there's a busy robin's nest there! The photo at left below shows the nest, which is just over 6 feet off the ground. That photo includes nearly the entire still-living tree. The right photo shows the four chicks in the nest...
Paradisical Perambulations...
Paradisical Perambulations... Debbie and I and the three dogs took a most pleasant walk up the road to our east this morning. The day could hardly have been nicer: blue sky with a few puffy clouds, 68°, 30% humidity, and a light breeze from the south. Lush green fields and pastures completely surrounded us. The dogs bounded through an alfalfa field that's nearly ready to cut. A few photos and a bounding video:
If Bernie Sanders didn't actually exist...
Progress in Paradise...
Progress in Paradise... Yesterday was the first day that the lawn was dry enough to even think about mowing – and the grass was nearly 6" high on average. The rains over the past 10 days really pushed the growth. So I mowed the whole yard, which worked better than I was expecting – the mower never sank into the soil, and the blades never clogged up with wet grass (though I did eject a few truly magnificent grass blobs!).
After I finished mowing, we headed up to WalMart to buy fertilizer. My brother Scott (aka Mr. Green Thumb) recommended Ironite, but the price of that (for our 3 acres of lawn) stopped me. We went for this stuff instead, for a small fraction of the cost. Strictly by the numbers, it should be good stuff, with nitrogen, potassium, and iron. We'll see. I spread 300 pounds of it yesterday afternoon in less than an hour, thanks to the tow-behind-the-mower fertilizer spreader I bought last year. That thing works great!
While I was doing all that, Debbie went to work getting our balcony ready for use this season. You can see the result in the photo at right, which I took just a few minutes ago (just after sunrise this morning). The view is to the southwest, over the Little Bear River's bottom and into the Wellsville Mountains. The little red cafe table you can just barely see comes with a couple of matching chairs, and there are four pots with roses and some other flowers. This is a very pleasant spot to sit and enjoy our morning caffeinated beverage, or a glass of wine in the evening. This morning we were visited by a hummingbird checking out the roses – and that immediately prompted us to order some hooks to hang hummingbird feeders off the balcony rail. If we're lucky, we'll attract some orioles too. We've seen a pair of Bullock's orioles along the irrigation canal on the south side of our property. If we keep food out, maybe we'll attract some more, like we did in Jamul!

Firewalls are dead?
I'd say that firewalls have been relatively ineffective for quite a few years now. Keeping a single firewall patched and configured correctly is a big job all by itself, perhaps impossibly so. Keeping all the firewalls a typical enterprise has patched and configured correctly is harder by a couple orders of magnitude. Add to that the fact that by their very nature, the protections of firewalls lag behind the threats in the real world. Firewalls are never up to date, even if you have the latest patches and configurations applied. Making the publicly-exposed apps secure is the first and most obvious step; making all apps secure is the holy grail.
In my last job before retiring, I worked with over a hundred large enterprise customers. There was a wide range on competence in their approaches to security, but by far the most popular approach was something like “buy all the right stuff, know all the right buzzwords, but actually know very little”. There were a few enterprises I worked with that actually had very competent, right-on-top-of-things security teams who took their work very seriously – but these were notable exceptions. There were many occasions when I was allowed physical access to “secure” facilities with no proof whatsoever of who I was (not even an ID check!), and many is the time I was allowed to plug my laptop right into their network. On a few memorable occasions I was given access credentials (including administrative access) to the company's critical systems. One time I called into a customer – a household name that anyone would recognize – I had never personally met, and at the end of the phone call I had VPN access and their Windows Domain Administrator credentials. Crazy!
But my favorite unsecurity experience involves a government organization (of course!). I won't name the city involved, but it was a large western U.S. city with a recently centralized IT department. The IT facilities were scattered around the city, in a couple dozen places; these were the formerly standalone facilities for each of the city departments. I arrived in town to help them deploy a test version of our product, and that required setting up a server in each of these facilities. The IT manager handed me a key ring with labeled keys for each facility, a spreadsheet with credentials for each server (they had about 200), gave me a map of the facilities locations, and told me to go for it. I was never asked for any identification, never asked to maintain confidentiality, and nobody even asked me for the keys and spreadsheet back!
I was frequently amused by IT organization's focus on things like firewalls. Most of them had far worse security problems than out-of-date firewalls, and the problems didn't appear to be on anyone's schedule to be fixed...

Porcupine Reservoir is full!
This is most excellent news for all of us in the southern Cache Valley who depend on Porcupine Reservoir for our summer irrigation water. Just a month ago everyone here was worried about a water shortage – now we're actually a little bit ahead of the water curve. Most years the draw from the reservoir would already have started. Not this year! We're sopping wet at the moment. The storm total ended up being 3.7 inches just north of Paradise, and it will have been something similar over the entire southern Cache Valley.
This is such a pretty drive for us, south from our home through the beautiful farms and towns of Paradise and Avon, then up the canyon to the reservoir. There isn't any stretch of that drive that isn't pleasing to the eye. This time of year, the fields are full of babies: colts, calves, kids, lambs, and more. The trees and waterways are full of chicks and fledglings. The fields are lush shades of green, as are the hills all the way up to the mountain peaks. Lots of plants are still in bloom, though that's winding down. The smells of farms and forest fill our nostrils on the whole trip, and the sounds of farm animals, birds, insects, and frogs are with us all the way. As I write this the sun is setting, and around our house we hear dozens of birds complaining about the night time that is about to start.
We feel lucky as hell to live here...
The new peace...
Medical instruments of a century ago...
Medical instruments of a century ago... I don't generally suffer from the “good old days syndrome” – and things like these are amongst the reasons why. Not to mention the fact that I would never have reached my age (62) a hundred years ago, because back then they had no idea how to treat my pernicious anemia. I would have died from it a couple of decades earlier...
Powerless in Paradise...
Powerless in Paradise... We were without power for several hours yesterday. The outage was caused by someone hitting a power pole just north of our place, snapping it off at the base. The pickup that hit the pole ended up in the irrigation canal alongside the highway, with its nose aimed right at our neighbor's (Tim and Jeannie D.) house! When I walked over to see if I could help, the police on scene told me everybody was ok; no serious injuries. Both Tim and Jeannie were away at the time of the accident, so I called Tim to let him know what happened – and he told me someone else had hit that same pole just a few years ago! The thing must have a target on it :)
We need a generator. We've lost count, but this is either the fifth or sixth power outage we've had this year...

A guy is driving around the back woods of Montana and he sees a sign in front of a broken down shanty-style house: 'Talking Dog For Sale'. He rings the bell and the owner appears and tells him the dog is in the backyard.
The guy goes into the backyard and sees a nice looking Labrador retriever sitting there.
'You talk?' he asks.
'Yep,' the Lab replies.
After the guy recovers from the shock of hearing a dog talk, he says 'So, what's your story?'
The Lab looks up and says, 'Well, I discovered that I could talk when I was pretty young. I wanted to help the government, so... I told the CIA.
In no time at all they had me jetting from country to country, sitting in rooms with spies and world leaders, because no one figured a dog would be eavesdropping.'
'I was one of their most valuable spies for eight years running...but the jetting around really tired me out, and I knew I wasn't getting any
younger so I decided to settle down. I signed up for a job at the airport to do some undercover security, wandering near suspicious characters and listening in. I uncovered some incredible dealings and was awarded a batch of medals.'
'I got married, had a mess of puppies, and now I'm just retired.'
The guy is amazed. He goes back in and asks the owner what he wants for the dog.
'Ten dollars,' the guy says.
'Ten dollars? This dog is amazing! Why on earth are you selling him so
cheap?'
'Because he's a Bullshitter. He's never been out of the yard'
Curiosity finds layers on Mars...
Curiosity finds layers on Mars... Tiny, thin layers. I'm no geologist, but to me this says WATER. All the ways I know that such layers can form involve water with minerals in solution, either invading a crack, or evaporating from a flat surface. This image was taken with the MAHLI camera, so it is highly magnified. It was processed with focus-merge, so there is an unusually deep field of focus. (Many) more here...

Two ways to see this...
Most software engineers viewing this will have the same reaction I did: some variant of “Holy crap!” Why? Because that robot is doing something that is incredibly challenging to program, especially in real time. Almost every element of that robot, from sensors to actuators, poses a very difficult programming challenge. That challenge is even harder if the solution you're seeking is a general one (i.e., let this robot run anywhere and jump over obstacles) as the MIT program is, and not a specific one (i.e., jump over this set of specific obstacles).
Most other people will look at this and say something like “Well, this is cool and all, but what else can it do? Just run?”
And in a very roundabout way, that's why I'm not too worried about artificial intelligence powered robots taking over the world anytime soon :) It's just too damned hard for conventional computers and conventional programming methods, no spectacular breakthroughs are around the corner (at least, none that I know of), and consumer expectations are light-years ahead of the reality. I suspect that the spawn of Roomba is what we can reasonably expect for quite a long time...

Lawn freckles...
Lawn freckles... For some time now, I've been trying to figure out why we have clumps of darker green, faster growing grass in our lawn. I called them “lawn freckles”, and the grass in them is what I'd like the whole lawn to have. You can see one of these freckles in the photo at right.
At first I thought these freckles were actually a different kind of grass that somehow was getting established in our lawn. Then I noticed that the freckles would come and go. The final clue was that the freckles never appeared where I didn't walk the dogs. That's when the lamp of understanding was illuminated: lawn freckles are where the dogs pooped and we failed to pick it up (with three dogs, it's sometimes hard to keep track of who's doing what at any given moment).
After doing a little reading (and multiple sources agree), I've discovered that the reason we have these islands of goodness instead of islands of burned spots is simply that its been raining all the time! When the rain stops – and it may have done so now – we're going to have little brown burned spots all over, instead of these freckles.
But I think the real message is that my lawn desperately needs some nitrogen. I think I'll be visiting the fertilizer store sometime soon now...

The “Coyote Principle”...
The “Coyote Principle”... Via my lovely bride:
CaliforniaHere in Utah, I think the solution would be even cheaper than in Texas. Our governor would most likely grab a nearby rock and bonk the coyote over the head, costing the taxpayers nothing...
The Governor of California is jogging with his dog along a nature trail. A coyote jumps out and attacks the Governor's dog, then bites the Governor.Texas
- The Governor starts to intervene, but reflects upon the movie "Bambi" and then realizes he should stop because the coyote is only doing what is natural.
- He calls animal control. Animal Control captures the coyote and bills the state $200 testing it for diseases and $500 for relocating it.
- He calls a veterinarian. The vet collects the dead dog and bills the State $200 testing it for diseases.
- The Governor goes to hospital and spends $3,500 getting checked for diseases from the coyote and on getting his bite wound bandaged.
- The running trail gets shut down for 6 months while Fish & Game conducts a $100,000 survey to make sure the area is now free of dangerous animals.
- The Governor spends $50,000 in state funds implementing a "coyote awareness program" for residents of the area.
- The State Legislature spends $2 million to study how to better treat rabies and how to permanently eradicate the disease throughout the world.
- The Governor's security agent is fired for not stopping the attack. The state spends $150,000 to hire and train a new agent with additional special training re the nature of coyotes.
- PETA protests the coyote's relocation and files a $5 million suit against the state.
The Governor of Texas is jogging with his dog along a nature trail. A coyote jumps out and attacks his dog.And that, my friends, is why California is broke and Texas is not.
- The Governor shoots the coyote with his state-issued pistol and keeps jogging. The Governor has spent $.50 on a .45 ACP hollow point cartridge.
- The buzzards eat the dead coyote.
Adventures in Paradise...
Adventures in Paradise... Just before we headed for bed last night, Debbie happened to glance out the window (it was still light), and noticed that our neighbor's horses were all excited about something. That's unusual behavior for them at that hour, so she looked around a bit for the source of the excitement – and noticed that another neighbor's cow and sheep had escaped their paddock.
That cow (which is named Anabelle) is about a year old, and is a Dexter. The photo at right is not of Anabelle, but it looks a lot like her. Those are small cows, bred to be useful for both milk and beef. They're also notoriously ornery. When we spotted Anabelle, she was practically dancing around the neighbor's parcel – she looked like she was about as joyful as a cow could possibly be. The sheep just followed Anabelle all over the place.
Well, we watched for a minute to see if our neighbors (Nick and Maria S., plus five kids) saw what was happening. We called them, but got their answering machine. Figuring they must not be home, we ran out – I dashed over on my ATV, and Debbie drove over.
By the time we got there, a couple minutes later, two of the kids (the only two who were home) had seen the commotion and were out trying to herd them back in. Another couple of neighbors also came over to help, and after just a couple minutes more, Nick and Maria came home with the rest of the kids. We had quite a crowd out there trying to corral the miscreants!
Nick quickly found the escape point: Anabelle had pushed the bottom of one stretch of fence up and out. He fixed that, and the rest of us ran around like mad men trying to convince Anabelle that she should go back in the paddock. Anabelle did not want to go back – she was really enjoying her freedom. Maria, we discovered, was already quite fed up with this ornery cow. We all sense hamburger (or possibly a sale) in Anabelle's future.
Debbie and I came home laughing about the experience. The animals' escape had turned into a very enjoyable social outing for us and several neighbors :)

Adventures in Wally World...
Adventures in Wally World... After a most enjoyable lunch at Jack's, we stopped at Walmart on the way home so I could run in and get a few supplies. I was standing in front of the paper towel display, somewhat bewildered by the selection on offer and trying to figure out which I should buy. Where I was standing was near the end of an aisle, so there were two passages near me – the aisle I was in, and the cross-connector aisle it abutted.
As I wrestled with my paper towel decision, I suddenly heard mad giggling. A little girl – maybe six or seven years old – burst around the corner. She looked like she was part Chinese, with long jet-black hair arranged in pony tails with big red ribbon bows tying them. Those pigtails were flying completely out of control, and she was waving her hands and giggling as she ran behind me. I turned around to watch her – her joy was infectious, and by the time she passed me and I was watching her disappear down the aisle, I was laughing myself.
Until suddenly I was knocked over, flat on my face. My empty shopping cart went scooting down the aisle, and I flipped over to discover that I had a young lady stretched out on top of me. It was the little girl's mother, a Chinese woman who was perhaps 25 years old, and in the process of changing her countenance from one of laughter to one of shock. Just as I was figuring out what had just happened to me, the little girl came running back – crying. It couldn't have been more than three seconds since she ran by laughing and giggling, and here she was somehow already crying and fearful.
A minute or so later, the little girl (named Chamomile!) was back to being happy. Her mom was just fine, and she was now worried about me. I was myself now pondering a completely different problem, this time of physics: how on earth could this woman (named Suzy), who couldn't weigh even 90 pounds and was only about 5' tall, have knocked me down with such force? I figure she must have traveling at about 0.5 C (half the speed of light, for you non-nerds) to have pulled that off!
Suzy fussed over me for a while, but eventually I convinced her that I wasn't likely to die anytime soon, didn't need an ambulance or even a medical exam, and she and Chamomile left to do their shopping. I finished mine and got into a checkout line with my shopping cart. It looked like something out of a cartoon, with giant plastic wrapped collections of paper towels piled perilously high. The clerk checking me out looked at my cart resignedly, and started scanning things. As she was ringing up my stuff, Suzy came over to check on me again. She seemed surprised to find me still conscious and apparently functioning :) After she left, my checkout lady was very curious about why all the fuss from Suzy, so I told her the story. She said, with a serious face, "We frown on knocking customers down at Walmart!" – and then cracked a smile.
All in all, I didn't really mind getting knocked down...

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):

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 ... on the fifth anniversary of “Everybody draw Mohammed” day. The lead:
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!”
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.Do yourself a favor and read the whole thing.
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.

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...

Watching this reminded me of an experiment I read of many years ago, wherein a man wore a pair of glasses that turned the world upside down. After a few days wearing these glasses, he saw the world right-side up again! Through the magic of Google, I found that experiment: it was done by Professor George Stratton in the 1890s. The underlying observations closely match those of this video...

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.

Mark Steyn at his best...
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.)Go read the whole thing!

Seven people I've known...
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...

1993 Camry recalled by Toyota... Because you really should have bought something new by now :) It's the Onion, folks. But it made me (a serial Toyota owner) laugh out loud. The average mileage on our vehicles is well over 150,000 miles – and we still think of them as new!

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.
