09:25 – Barbara’s been gone 48 hours. Surprisingly, Colin seems to be doing pretty well. He’s not pestering any more than usual, nor demanding that I Do Something about Barbara being missing. Like most Border Collies, Duncan and Malcolm were one-person dogs, and that person was Barbara. They tolerated me. When Barbara and I were both out of the house and I came home alone, Duncan and Malcolm would bark like crazy to celebrate Barbara’s return. When they saw it was just me, they’d say, “Oh, it’s just you” and go back to watching/listening for Barbara’s return. Colin seems to be a two-person Border Collie, and he’s happy as long as at least one of us is with him.

I ran myself flat out of the CK01B chemistry kits this morning. Fortunately, I have everything I need for a dozen more sitting on the shelf, so it’s just a matter of boxing them up. We’re also down to four of the BK01 biology kits as of this morning, so I’ll get another dozen or two built over the next couple of days. Come to think of it, I’m out of the iodine solution, so I’ll have to make up another two liters of that and fill bottles before I can build more kits.

Our thoughts are with the flooding victims in Colorado. I just read an article that mentioned that evacuations were voluntary, but those who decide not to evacuate their homes are being warned that they could be without water and power for weeks to months. Given that many roads and bridges have been utterly destroyed and will require months to years to be rebuilt, those folks may literally have to hike out if they change their minds. And, of course, emergency medical care will be unavailable or at least very slow in arriving.

09:20 – Costco run and dinner with Mary and Paul yesterday.

As Barbara will tell you, I tend to spread like kudzu. I presently have kit components stacked in the kitchen, den, dining room, library/living room, workroom, my office, the downstairs finished area, and the downstairs unfinished area. My stuff just spreads. And that’s just the science kit stuff. We also keep stored water, probably something like 300 or 400 liters, in 2- and 3-liter soda bottles, crammed into every free space downstairs. So before our Costco run yesterday, I suggested to Barbara that we replace that stored water with bottled water from Costco, which should be more space-efficient to store. She buys it anyway, in cases of 35 500 mL bottles which translates to 17.5 liters per case or 8.5 two-liter soda bottles. So I told her that for every two cases of bottled water we buy we can empty and recycle 17 two-liter bottles. She was delighted. I figure that once we get up to 20 cases of bottled water, all the 2- and 3-liter soda bottles will be gone.

So, just as we got to the checkout line at Costo, they opened another register. Paul and I got in that line with their cart, with Barbara and Mary right behind us with our cart. After Paul and I got checked out, we were standing watching our stuff being loaded back onto our cart and I commented to Paul that although the math told me it was true, those two cases of bottled water just didn’t look like the equivalent of 17 two-liter bottles in terms of cubic. He agreed with me but, as he said, when the math says one thing and your intuition says another, the math is always right. Assuming you do good math.

At dinner, we were talking about allergies. Mary has terrible allergies to dogs, cats, horses, and presumably other mammals. So bad that it’s possible that they’d be life-threatening without antihistamines. She has to get herself all drugged up on antihistamines before she can even ride over to Costco in our SUV. And this season has been horrible for allergies. I go years without taking an allergy pill, but lately I’ve been taking a loratadine (Claritan) every evening because my eyes have been itching and burning so badly. Given the constant rain for the last two or three months, I suspect it’s mold spores.

And Colin has been suffering badly as well. Barbara has been giving him diphenhydramine, which doesn’t seem to help much. I’d been meaning to check on loratadine in canines, and I finally did it after we got home. I turns out that loratadine is generally safe in canines, with a usual dosage of 0.5 mg/kg once a day, so Barbara gave Colin a 10 mg loratadine tablet this morning. That’s a light dose; for his body weight he should be getting 15 to 17 mg, but we wanted to start out easy. She gave it to him about 7:00 this morning. At 8:15 he was still scratching, but we’ll give it a chance.

One thing I didn’t realize is that the effectiveness of different classes of antihistamines varies widely in dogs, even more so than in people. One class or one specific drug may be completely ineffective and another very effective. So, if the loratadine works, great. If not, we’ll try chlorpheniramine maleate or one of the others.

Work on science kits continues. I’m trying to finish up the virtual school AP chemistry kits in the next couple of days. Today, I need to get the batch of pH 7.0 buffer standardized and dry some stuff to constant mass.

11:22 – Colin had a pretty bad evening. He’s only two years old, but he’s already terrified of fireworks. Someone in the neighborhood was setting off heavy stuff. Not just little bottle rockets and firecrackers, but serious rockets with heavy bursting charges, and in large numbers. Hell, they may even have been using a pyrotechnic mortar. Colin jumped every time one of the heavy ones detonated. I’m guessing that whoever was doing it probably burned at least $1,000 worth of fireworks.

I’m working today on internationalizing the biology and chemistry kits, which involves changes to a few of the chemicals in each. In many cases, we can comply with international hazardous materials shipping regulations simply by decreasing the concentration and increasing the amount. For example, the standard biology and chemistry kits include 15 mL of 6 M ammonia, which is hazardous according to IATA. So we’re going to substitute 30 mL of 4 M ammonia in the international kits, which makes it perfectly legal to ship.

For one or two chemicals, the change is more radical. For example, we ship 30 mL of 6 M (~ 20%) hydrochloric acid in our US kits. The maximum concentration allowable under IATA regulations is < 1%, or about 0.3 M. So we'll ship 100 mL of that, which is enough to get most of the labs done. The really annoying thing is the IATA rules on sodium (or potassium) hydroxide, for which they have zero tolerance. Shipping even one mL of 0.001% hydroxide solution violates their regulations. Fortunately, in most countries it's pretty easy to get ahold of solid sodium hydroxide, which is sold in hardware stores, DIY centers, and so on as "lye" or "crystal drain opener". So for hydroxide we have no option but to tell international buyers they'll have to get it locally.

The rest of the changes are pretty minor. For example, in our US kits we ship 15 mL of Sudan III stain solution, which is a tiny amount of the solid stain dissolved in isopropanol (rubbing alcohol). The only way to ship IPA legally under IATA regulation is at a concentration much too low to dissolve the stain powder. So we’ll ship a bottle that has only about 6 mg of the solid stain in it. International buyers will have to fill the bottle with 15 mL of rubbing alcohol and let the stain dissolve.

We’ll ship international kits via USPS Priority Mail International in boxes we provide, rather than using USPS-provided boxes. Although the boxes cost us a buck or so each, the postage will be at least a few dollars less than it would be if we used a USPS Large Flat-Rate Box.

Other than the chemical differences, the main difference for international buyers will be that they’ll have to pay postage. We won’t know exactly how much until we can get a weight for the international kits, but for the biology kits I’d guess we’re probably talking a postage surcharge of maybe $40 to Canada, $50 to Mexico, and $60 to the UK and most of the rest of Europe. Of course, depending on country, they may also have to pay import duties, VAT, or other fees to the postal carrier when the box is delivered.

The other difference is that for international sales we have no option but to ship FOB Winston-Salem, NC USA. In effect, that means our responsibility ends when we hand the package to the USPS carrier. All risk of loss or damage is assumed by the buyer. We may offer insurance at an additional cost, but it isn’t cheap and it may take literally months to settle a claim for loss or damage, assuming it’s settled at all.


17:25 – I just made up a liter of 0.5 M dipotassium oxalate solution for the international chemistry kits. Which of course gave me a good question for the AP chemistry course I’ll eventually write…

When I was in high school, all of the seniors took the Kuder test. It was intended to come up with recommendations for the careers we were best-suited to pursue. My top three recommendations were, IIRC, research scientist, university chemistry professor, and high-school science teacher. I suspect if I’d been a high school or university science teacher my students would have feared and loathed me.

So, here’s the question I came up with: “You dissolve 56.1056 grams of potassium hydroxide (FW 56.1056 g/mol) in 1000.0 mL of 0.5000 M oxalic acid to make a solution of dipotassium oxalate. To four decimal places, what is the molarity of that solution? If you have insufficient data to answer the question, specify what additional datum or data you need.”

Heh, heh, heh. I remind me of my ungrad p-chem professor. Each test day, he wore his test t-shirt, which had an image of an erect middle finger on the front.

07:29 – Barbara’s dad is likely to be released back to the Brian Center in the next couple of days. Brian Center called Barbara yesterday to ask if she wanted them to hold his room. She told them yes, even though they’ll have to pay something like $275/day themselves to hold the room. (Obviously, Medicare isn’t going to pay for Dutch to be two places at once.) Barbara was concerned that otherwise Brian Center wouldn’t have a room available when her dad was discharged and he’d end up somewhere else that wasn’t very good.

We had an all-time record for kit orders yesterday, with 21. Of course, 20 of those were to one customer, a small private school. Still, that means that through the first five months of 2013 our kit sales and revenues are more than 50% of the total for 2012. And in 2012, we did only about 10% of the year’s business in the first five months. So of course we’re desperately trying to get more kits built in time for the summer rush.


16:35 – Geez. Colin just scared the shit, almost literally, out of the replacement mail carrier. The front door was open, with just the glass storm door between him and the mail carrier. Colin acts like a berserker when someone approaches the door. Fangs, snarling, loud barks, ramming into the glass, and so on. I’m not even slightly afraid of dogs, but given Colin’s threat display I sure wouldn’t want to mess with him. A pissed-off dog that weighs 80 or 85 pounds is no joke. Of course, if I’d opened the door and let him out, he would have made a big fuss over the mail lady, licking her hand and so on.

But I yelled at him to shut up and then opened the door and went out. The mail lady summed up her feelings pretty well. She asked me, “Are there just the two of them?”

08:26 – Barbara’s dad arrived at the Brian Center nursing home just before lunchtime yesterday. I stopped over to see him as Barbara was helping him get settled in. He’s currently on the second floor, which is the skilled-care (nursing home) floor. We’re hoping that he’ll soon be well enough to move downstairs to the assisted-living floor. The Brian Center is one of the best-rated facilities around here, which is why we chose it for my mom when we had to move her to a nursing home. That was 10 years ago, and the place doesn’t seem to have changed much. A few of the staff from back then are still there.

One of the things I found most impressive about the place is that there’s no odor. Not only no urine odor, but no pervading smell of disinfectants. The place just doesn’t smell at all, which is very difficult to accomplish in a nursing home. There are plenty of staff, and they’re all friendly. Dutch was eating lunch when I arrived, and he said the food was good. And, of course, the place is only a couple miles from our house, so it’s easy to get over there for frequent visits.

While we were there, I asked one of the senior staff members about something that had been bothering me. When my mom was at Brian Center, she had an extraordinary nurse, whose name I couldn’t remember. It was LaToya. LaToya was a delightful young woman, and my mother loved her. She was 23 years old, and a single mother of a toddler. One day, she wasn’t at work. Nor the next, nor the next. We asked about her, and were stunned to learn that she was in the hospital and not expected to live. Shortly after, we learned that she had died of a rare genetic condition. My mother was inconsolable, not just because LaToya had been her favorite nurse, but because LaToya was only 23 years old and left a young toddler motherless. I couldn’t believe I’d forgotten her name. She deserves to be remembered.

Colin was due for his annual checkup, so around 4:15 we headed off to the vet, making a stop at Dutch’s apartment on the way to pick up some stuff for him. The traffic was hideous, as always, but we managed to make it out to Clemmons in time for the 5:15 vet appointment.

Our vet is Sue Stephens, and we’ve been taking our dogs to see her for about 25 years. She originally had her own practice not far from us, but 15 years ago or more she sold her practice. She’d signed a non-compete that restricted her from practicing near her old practice, and she ended up working part-time at a practice out in Clemmons. Driving out there is a pain in the ass, but Sue is the best vet I’ve ever known, and we considered it worth the hassle to continue seeing her, particularly when we had older dogs with more health problems.

So, we got out there and, as always, the first thing was to get Colin on the scale. The scale wasn’t cooperating very well, refusing to settle at 0.00 even when tared. On the first attempt, Colin weighed 85 pounds (~ 39 kilos). On the second, 81 pounds. On the third, 82 pounds. I stepped on the scale, which said I weighed 203.4 pounds (~ 93 kilos). So, we concluded that Colin likely weighs somewhere around 83 pounds. Sue wants to see Colin down to 68 pounds, which we think is ridiculous. He’s not fat now. At 68 pounds, he’d look anorexic.

I asked Sue if there was any factual basis in terms of morbidity or mortality for the recommended weights vets use for dogs. There apparently isn’t, other than one study Purina did many years ago, in which they apparently didn’t bother even to define their terms. I told Sue this reminded me of the recommended weights physicians use for people. Morbidity/mortality is significantly lower for people who are “overweight” versus those who are “normal weight”, which pretty definitively establishes that so-called “overweight” is in fact the proper weight and what they define is “normal weight” is in fact underweight. And any normal person looking at Colin would not think he was too heavy. We’re not going to make any significant changes to his diet unless and until he actually starts to look chubby.

Nor me, for that matter. On our wedding day, I was 30 years old and weighed 238 pounds. Over the last 30 years, and particularly over the last 5 or 10, my weight has been gradually decreasing. It’s not that I’ve been trying to lose weight; it’s just that I eat less and less as I get older. As I said to Barbara yesterday, I’m now almost down to my tennis-playing weight of 185 to 190, and maybe I should take up the game again. I quickly assured her that I was only kidding. With vertigo affecting my balance and some arthritis in my hands, there’s no way I’d even attempt it.

We’re on schedule to start shipping the LK01 Life Science Kits on Monday. There are 30 of them on the assembly table right now that are nearly complete, missing only a few components. We’ll finish them up this weekend.

07:58 – We still don’t know exactly what the problem is with Barbara’s dad. At one point yesterday they were talking about moving him to the ICU, but they decided not to, so he’s on a regular floor. They started antibiotics immediately, in case his lung infection is bacterial, but we won’t know for sure until the results of the culture come back. At this point, it appears that Dutch isn’t in any immediate danger.

We’d planned to do a Costco run and have dinner with our friends Paul and Mary yesterday. Barbara was adamant that we proceed with our plans, even if I had to go without her. But she called from the hospital around 2:30 and said she was on her way home. So we went to Costco and then out to dinner normally, and then came back home so Barbara could watch the end of the Masters golf tournament. Barbara’s going to work late this morning. She has to stop over at her parents’ apartment to pick up the checkbook and her mom, drop her mom at the hospital, and drop a couple of checks at her parents’ accountant’s office to send in with her parents’ tax returns.

All of the neighborhood dogs know that I carry dog treats when I’m walking Colin. Sophie, Kim’s 5-month-old Yorkie, learned that the first time I gave her one, and now every time we visit Kim and Sophie Sophie begs shamelessly for treats, standing with her front paws on my leg and bouncing up and down. I always give Colin his treat first, because to give Sophie hers first would offend Colin’s sense of order. He is, after all, both the senior dog and my dog.

So, yesterday, I was handing a treat to Colin, but we dropped it. Colin bent his head down to pick it up off the sidewalk, but Sophie got to the treat at the same time Colin did. She lost the struggle for the treat, of course. Colin is 15 or 20 times her weight, and her whole body is about the size of his head. But I was amazed that he didn’t even growl or show his fangs at her, even though she was literally trying to pull the treat out of Colin’s mouth. Kim was watching fearfully and probably assumed her puppy was about to be eaten. After seeing what didn’t happen, I told Kim that if she needed any evidence that Colin wouldn’t hurt Sophie she’d just gotten it in spades.


11:08 – Barbara just called to let me know she’d gotten to work. Her dad is doing better. He has pneumonia, again, but it appears to be responding to antibiotics. He’s still very confused. He told Barbara he’d been in the hospital for two days and they’d given him nothing to eat. She tried to convince him that he’d just gone in yesterday afternoon and that they were in fact feeding him, but he’s as contrary as usual. Some of his confusion may be due to the illness and some to the antibiotics they have him on. They’re moving him from intermediate care to a regular room today.

08:48 – We decided not to continue our subscription to Acorn TV beyond the 30-day free trial. There’s just not enough content there to make it worth our while. It’s not the price, which is only $3/month or $30/year. It’s the hassle of figuring out what’s on when on Acorn and keeping track of what we’ve watched on Acorn streaming versus what we’ve watched on Netflix streaming. If Acorn had any sense, they’d offer to merge their content with Netflix’s in return for a small monthly license payment, maybe $0.10/month per Netflix subscriber. Acorn would make more money without having to run its own streaming operation, and Netflix’s catalog would improve. My guess is that Acorn hasn’t done that because they have the rights to stream the material themselves but not to sub-license it. None of this would be a problem if the powers that be would just rationalize copyright, reducing it to one year at most and then putting everything into the public domain.

Colin has a new little friend. He now likes to visit Sophie, Kim’s five-month-old Yorkshire Terrier puppy. The two of them go tearing around in circles in Kim’s front yard, with Sophie chasing Colin and Colin trying to herd her. She’s fast for a little girl. The expression on his face the other day was priceless when Sophie ran between his front legs, underneath the length of him, and back out between his back legs. At first, Kim was afraid Sophie would get hurt playing roughly with Colin, but he’s very careful not to step on her. She’s about the size of Colin’s head, maybe four pounds or so, but she’s fearless. Periodically, the action stops when Colin goes into his herding crouch. Sophie walks over to him and they touch snouts. Then she reaches up and licks his nose.


11:30 – I see that the Portuguese government is on the verge of collapsing, which calls into question the Troika’s continuing bailout. If Portugal, like Italy, is unable to form a new government quickly, it’s likely that Draghi’s promised unlimited backstopping of Portugal’s sovereign bond yields will not be honored, thereby putting Portugal quickly into default. Germany is fed up with paying the bills of the southern tier, and at some point will simply refuse to continue doing so. Merkel wants the election this autumn out of the way first, but her voters are growing increasingly restless. At some point, the whole house of cards is going to come tumbling down. It’s possible that Portugal will cause that to happen, but I think it’s more likely that Italy will be the straw that breaks the camel in half. An increasing number of economists are betting that Italy will be the first eurozone country to depart the euro, although Portugal, Spain, Cyprus, and Slovenia are also likely candidates. Greece, of course, is hanging onto the euro for dear life. Without the euro, Greece is completely toast. Of course, with the euro, Greece is also completely toast.

09:09 – Spring arrived here as expected on the 20th, with sunny skies and warm temperatures, but it’s disappeared again. Our highs over the next several days are to be in the mid- to upper-40’s (< 10C) and lows near freezing.

Colin and I almost got into a fight yesterday afternoon. I was walking Colin on the 10-meter roller leash and he was sniffing around in Kim’s front yard when we spotted Jack, a neighborhood dog, approaching at a dead run. Jack is a full-size poodle, roughly Colin’s size. Jack circled around a large bush in Kim’s yard, came to a stop between me and Colin, and then snarled and lunged at Colin. Colin’s hackles rose and he responded with a snarl of his own. It was looking like a serious dog fight was about to break out, and I was getting ready to kill Jack with a snap kick. I yelled as I began the kick, and Jack took off running toward home.


09:50 – I’ve never paid much attention to visitor stats. I write this page for myself. If people visit and comment, great. If they don’t, I’d still write it. But I just checked my visitor stats this morning, and the contrast between now and the Good Olde Days is striking. Nowadays, I get maybe 30,000 visitors per month, and maybe 1,200 on a good day. Back when I was writing computer books, I got much more traffic. Days with 8,000 to 10,000 visitors were routine, days with 15,000 to 20,000 visitors weren’t uncommon, and I think my best day ever was more than 30,000 visitors. In other words, back then I got about as much traffic on a very heavy day as I get nowadays in a month.

08:21 – Happy Darwin Day, and happy birthday to Colin, who’s two years old today. In fact, over the weekend I suggested to Barbara that we change Colin’s name to Darwin, but she wouldn’t hear of it.

Barbara’s heading over to the hospital this afternoon to pick up her mom and take her home. She and Frances have been scrambling to get day-time care lined up. The doctor suggested that they have someone there with Sankie during the day as well as at night for at least a while because they’re afraid she won’t be able to cope physically with things until she’s recovered a bit more. Barbara is not optimistic, expecting another crisis will occur soon with her mom, her dad, or both. I think they both need to be moved to a skilled-care facility. Independent-living or even assisted-living is simply no longer appropriate for them.


16:23 – I spoke to Barbara a few minutes ago. Her mom is now home and seems to be doing as well as could be expected. She’s still physically frail, which is to be expected at her age and coming off a 16-day hospital stay. Mentally, it’s a mixed bag. Barbara says she remembers things like the year they moved into their house, 50 years or so ago. But she’s confused about why she was in the hospital. I told Barbara to give her a day or two to get used to being home before she worries too much about her mom’s mental state. It’s never easy being in the hospital, let alone for someone Sankie’s age. The aide they’re hiring to day-sit was over there when I talked to Barbara. Barbara vaguely recognized her. It turns out that Barbara went to elementary, junior high, and high school with her.

08:41 – The cops never, ever stop looking for a cop killer. In October, 1996, a local cop, Gregory Martin, radioed in that he was making a traffic stop and requested backup. A state cop soon arrived at the scene and found Martin dead on the ground by the side of the road and no one else in sight. The morning paper says three suspects are now in custody and have been charged with first-degree murder. If they’re guilty, I hope they’re executed. Anyone stupid enough to kill a cop is too stupid to live anyway.

Barbara spent the night with her dad, and is going straight into work from there. No word yet on when her mom will be released from the hospital. Sankie is suffering from sleep deprivation and hunger. No surprise, since she hasn’t been able to sleep or eat since Dutch came home from the hospital last time. There may also be other things going on, including possibly pneumonia and a UTI. Barbara said she may be released tomorrow, but I’d be surprised. Barbara and Frances are looking into getting someone to sit with Dutch and Sankie on a temporary basis, but unless/until that happens it looks like they’ll be taking turns staying over at her parents’ apartment themselves.

Last night, Colin and I played ball and finished series four of Heartland. Barbara is home tonight, unless something changes, but will probably being staying with her dad tomorrow night. If so, Colin and I will start on series five of Heartland. Series six is running now on CBC, and I’m bittorrenting HD versions of the episodes as they air. (I keep my upload speed throttled to 0.0 KB/s, so I’m breaking no laws by downloading them; I’m not “making available” by uploading.)

The HD episodes are about 1.4 GB each, and are typically in .mkv format. The old version of DeVeDe that I use to create video DVDs doesn’t work properly with .mkv files, so I run the .mkv files through ffmpeg to convert them to mpegs, which DeVeDe handles well. I end up with six DVDs per season, three episodes per DVD. Only the first 12 episodes of series six have aired, with the final six to be aired in February and March. The good news is that series six is getting higher ratings than series five did, so there should be a series seven.

We continue to build science kits. Right now, I’m working on the new LK01 Life Science Kit.


08:59 – Barbara just sent me this video of a Border Collie trying to force an uncooperative horse to do what it’s told. Boy, does this look familiar. I see it every time I walk Colin. The only difference is that on those walks I’m the horse.


10:21 – One of the good things about my lab is that I have lots and lots of glassware and plasticware. Hundreds of individual items: beakers, graduated cylinders, volumetric flasks, funnels, stirring rods, and on and on. That means I almost always have a clean whatever-I-need. But one of the bad things about my lab is that I have all that stuff. When I use a vessel, I just rinse it and put it in the sink to be washed later. The problem is, later never comes until I have piles of stuff in the sink and covering all the counters on both sides and usually the floor, by which time cleaning up my lab becomes an Augean Stable thing. The other day, Barbara was cleaning downstairs and was about to step into my lab. She flipped the lights on, immediately flipped them back off, and just turned around and walked away.

So yesterday I decided I’d better get started on cleaning up my lab. It’ll take a while because I’m going to do it gradually. I couldn’t get to the sink in the lab, so I filled a 10-gallon (40 liter) bin with dirty glass/plasticware and carried it upstairs to the kitchen to wash it there. (Most of the stuff was already reasonably clean, so there’s no real hazard to washing it upstairs.)

The goal is to get the floor, counters, and sink in the lab completely empty and clean. That’s going to take some doing. I decided this task needed a name of its own, so I’m calling it Operation Overlord.
