09:04 – As I expected, kit sales have fallen off a cliff. None overnight or so far today. If last year is any indication, we’ll probably sell half a dozen kits during the last week of the year, and that’ll be it until the New Year.

Barbara is off until next Wednesday and then most of that week. She’s starting this morning on her Deep Clean, beginning with the finished area downstairs. Last week, we donated a sofa and table/chairs to a moving company that transports used furniture to people who need it, freeing up some space downstairs. Barbara will vacuum the floors, walls, and ceiling in the areas that are currently open, we’ll move furniture into those areas, and then she’ll vacuum the newly freed-up areas. After a couple of iterations, we should have the whole area clean and the furniture where it’s supposed to be.


11:04 – Barbara is making a lot of progress in the finished area of the basement. Out in the garage area, I just used the last new 4-foot fluorescent tube I had in stock to replace a flickering one. Three or four of the six 4-foot tubes in my lab are starting very slowly now, so I need to re-stock on fluorescent tubes soon. I was expecting replacing all ten in the basement and six in my lab to be an expensive project. The last time I bought a fluorescent tube was probably three or four years ago, when I replaced the 2-foot 20W tube in the kitchen. At the time, I though the price was outrageous, something like $12 for that one tube. But I just checked the Home Depot web site, which sells 10-packs of 4-foot 40W 2300+ lumen 6500K tubes for $25 or $30. Now the only problem will be disposing of the old tubes, which can’t just be thrown in the trash.

08:12 – Happy Birthday to Barbara. She turns twenty-thirty-eight today. She’s off this morning to have brunch with her parents. We’ll go out to dinner tonight. It’s hard to believe, but we’ve now been together for more than half of our lives.

We finished the first series of Reven8e on Netflix streaming last night. Barbara commented that it was one of the best series she’d ever seen. Oddly, although Emily VanCamp is both the narrator and lead character of the series, she receives only second billing.

08:23 – Barbara is off to visit the craft fair with her friend Bonnie and Bonnie’s sister. Late this afternoon, she’s going to meet her sister and sister’s husband at her parents’ old house and haul some stuff back here. It’s a normal work day for me.

I canceled the disc part of our Netflix membership yesterday. After seven months, the only discs left in our queue are ones we really don’t care much about. Stuff that I’d stuck in there because it looked like it might be interesting. We’ve been doing the six-months-on/six-months-off thing with discs for a couple of years now. After six months without, they might have some discs we really want to watch. In the interim, we’ll just watch streaming.

Speaking of streaming, I noticed that the Roku box gives interesting hints about what might soon be coming up on Netflix streaming. For example, for a year or more Netflix streaming has had only the first 45 episodes of Heartland: all of series one and two and the first 14 of 18 episodes in series three. A week or so ago, the main titles screen on Roku changed to show Heartland as having 67 episodes available rather than 45. That’d be all 13 episodes of series one and all 18 episodes each of series two, three, and four. Same deal on Army Wives, which Barbara likes. The Roku main titles screen changed from showing 81 episodes available–all of series one through five–to 104 episodes, suggesting that all 23 episodes of series six are likely to be available soon. We knew that series six, part one (13 episodes) would release streaming on 18 December, but apparently Netflix has signed to carry the ten episodes of series six, part two as well.

Today I’m building the first small batch of one of the two new science kits. It’s the CK01B Chemistry Kit, a simplified, less expensive version of the current CK01A kit. I’m also getting ready to build a small initial batch of the second, the LK01 Life Science Kit. We’ll go into full production of both new kits on or around 1 December, once full shipments of all the necessary components arrive here.


09:48 – I just ran the numbers, and Netflix must be delighted that I dropped the DVD service. In seven months, Netflix sent us a total of 62 discs for a total cost to us of $55.93, not including tax. That’s $0.90 per disc, which is less than their cost of postage. When you consider that we also watch a lot of streaming video, we’re the Customers from Hell as far as Netflix is concerned.

Every time I contact Netflix customer support, I beg them to increase the monthly price for streaming. At least double it, to $16/month, and tripling or quadrupling it would be better. That’d give them the money to get more stuff streaming and get it sooner. They wouldn’t lose many customers, when you consider how much cable TV costs, and they could soon wind down their disc rental business. They could do direct deals with the companies that actually produce network TV shows and cut the networks out of the picture entirely. They could even eventually get into streaming sports and other live events, which’d kill cable TV.


10:53 – I just read an article about baby-boomers being the first generation to retire while in debt. The article included the following statement:

According to the report The Plastic Safety Net by public policy organization Demos, Millennial’s (those born after 1980) average credit card debt is $2,982. For those 65+, the average credit card debt is $9,283—and that amount could continue to rise as they age since they have fallen into the trap of financing their lives on credit cards.

But what does that really mean? Barbara and I have been married for 29 years, and every month we’ve had a balance due on our credit cards, which we’ve paid in full every month. So, does this statement refer to current account balances or to overdue balances? There’s a big difference. We have “fallen into the trap of financing [our] lives on credit cards” but we pay off that balance every month. Does that count?

09:01 – Barbara is leaving late this morning to meet her parents and sister to spend the day celebrating Thanksgiving. I’m not much for holidays, and certainly not religious holidays, so today is just another work day for me. Barbara will bring me food when she returns this evening, I hope not including any turkey. It’s not that I dislike the taste of turkey so much as that I think it’s a bad idea to eat something so stupid that it can literally drown while drinking because it forgets to take its head out of the water.

I ran out of chromatography paper envelopes while I was building kits yesterday, so Barbara is going to label and stuff another 60 of those before she leaves. That gives me enough to finish building 30 each of the chemistry kits and biology kits, as well as some prototypes of the two new kits. I also have a case of glass Petri dishes that’ll be in one of the new kits. We have to figure out how to package those so they can survive shipping. I know we’ll use bubble-wrap; I’m just not sure yet which type or how much.

Barbara has been encouraging me to get a tablet. I’ve hesitated because I really prefer something with a real keyboard. I’d been thinking about buying a ChromeBook, so yesterday I went ahead and ordered one from Google. I’ll probably give it to Barbara, but I may use it from time to time.


11:45 – In designing science kits, I end up doing all kinds of little experiments that have nothing directly to do with the lab sessions covered by the kits. I’m doing one of those today.

One of the new kits I’m designing right now is the LK01 Life Science Kit. Life Science is basically middle-school biology, a simplified version of a first-year high school biology course. One of the classic experiments that’s covered at both levels is antibiotic resistance in bacteria. Our full biology kit includes four antibiotics: amoxicillin capsules, chlortetracycline and sulfadimethoxine powder, and neomycin liquid. But to simplify things for 7th and 8th graders and to keep the cost of the kit down, I decided that the LK01 kit would include three antibiotic test papers–amoxicillin, neomycin, and sulfadimethoxine–rather than the actual antibiotics.

I’m going to make the antibiotic test papers myself, by soaking letter-size sheets of chromatography paper in solutions of the antibiotics. But I need to have at least an approximate idea of the concentrations of the antibiotics in micrograms per square centimeter. To do that, I need to know how much liquid one sheet (about 600 square centimeters) of chromatography paper will absorb. Knowing that, I can calculate how concentrated the antibiotic solutions need to be. So, to determine that factor, I’ll weigh a sheet of dry chromatography paper, soak it in water, reweigh it, and determine how much liquid it absorbs. I don’t expect a lot of variability, but I’ll do several sheets just to get a reasonable idea of how much actual variation there’ll be.

But I can’t simply use blank sheets of chromatography paper. The test papers included in the kit will be roughly 4 by 5 centimeter pieces, so I need to pre-print each sheet with “amoxicillin” or whatever in tiny little print. That may affect the absorbency, so it has to be taken into account.


14:06 – Well, it is a national holiday, so I’ve decided to take the rest of the afternoon off and watch Heartland re-runs. I only have 1.5 episodes left on Netflix streaming, so it’s time to fish out the boxed set of series three to watch the four remaining episodes in series three and then start series four on disc.

09:29 – I’m amazed that Israel has responded with such restraint to islamic terrorists launching hundreds of missiles a day into Israeli territory. Israel has responded with just a couple hundred surgical airstrikes that give high priority to minimizing “civilian” casualties. If islamic terrorists in Gaza were launching 300 missiles a day at me, I’d be inclined to cover the entire Gaza Strip with cluster bombs and burning napalm, and the hell with “civilian” casualties.

There’s no doubt that the goal of Hamas is to destroy Israel and wipe out its population. They’ve said as much. Why should Israel show any restraint? The obvious answer is that Netanyahu is afraid of American public opinion turning against him, and more particularly of Obama withdrawing diplomatic and logistical support.


Barbara is cleaning house today. I need to get the library cleared out, as well as some stuff I have stacked in the den. We’ll be moving Saturnalia decorations upstairs today, and she needs those areas clear.

08:41 – Barbara’s dad was released from the hospital late yesterday afternoon. He’s at home and seems to be doing fine. And he’s using his new walker.

As usual for a Saturday, I’m doing laundry. Barbara is getting ready to head outside and do some yard work. This afternoon, we’ll work on kit stuff. The seasonal slow-down in kit sales makes it tempting to ease off a bit, but with Christmas and the start of the winter semester just around the corner kit sales are likely to pick up again late this month and into December so we need to build some inventory.

We also need to make time for a Costco run in the next couple or three weeks. We don’t actually need that much for current consumption, but I want to stock up on food. With food prices increasing every month, it just makes sense to buy now instead of waiting for prices to increase.


11:47 – This is interesting. Netflix has started throttling me again. That hasn’t happened for several years. All of that time, a disc I returned one day would be received by Netflix the following day (other than Sundays) and they’d send my next disc that same day. Since we changed to the one-disc-at-a-time plan, we’ve reliably gotten two discs a week, every week. A disc arrives on Monday, we send it back Tuesday, Netflix logs it as received and sends out the new disc Wednesday, we receive the disc Thursday, send it back Friday, Netflix receives it Saturday and ships us a new disc, which arrives Monday. Lather, rinse, and repeat. But for the last two discs, Netflix has delayed acknowledging receipt for an extra day, turning the normal three-day cycle into a four-day cycle. I wonder what’s going on.

09:46 – Barbara’s dad is supposed to be released from the hospital this afternoon. He’s adamant that he won’t use a walker, despite the fact that everyone from his wife and daughters to the doctors, nurses, and physical therapists are telling him that he needs to. I told Barbara the solution is simple: just put the walker beside him and take away his cane. She says this latest fall really scared him, but apparently not enough. I’m afraid the next fall might kill him. And if he continues to use that cane, there will be another fall, probably sooner rather than later.

My search to find a way to prevent iodine solutions from outgassing continues. The problem is that iodine vapor really, REALLY wants to be free. The bottles aren’t leaking, but they are allowing tiny amounts of iodine vapor to escape. I’ve tried different bottles and caps. I’ve tried various types of tape, including stretched vinyl electrical tape and even Teflon tape. I’ve tried several different types of LocTite. Most of them kind of work, most of the time. But if we make up 30 or 60 bottles of iodine solution and stick them in a ziplock bag, at least one of them is almost certain to allow some iodine vapor to escape, which stains all of the labels dark brown. It’s only a cosmetic problem, but I’d like to solve it.

So I ordered a pint (473 mL) of Elmer’s original rubber cement, which is essentially pure latex rubber dissolved in n-heptane. Yesterday, I filled a 30 mL bottle with the IKI solution, brushed the bottle threads with a cotton swap dipped in the rubber cement, and screwed on the cap. So far, it appears to be working, at least for that bottle. I guess I’ll make up 30 or 60 bottles of the IKI solution with the rubber cement seal and see what happens. The bottle is LDPE and the cap is HDPE with a PP liner, none of which are severely affected by short-term exposure to n-heptane. But I do want to make sure that the solvent doesn’t weld the cap to the bottle. I should probably have gotten Obama to do this for me. Bastard.


11:31 – Nothing is ever easy. Barbara gives Colin a heartworm preventative called Interceptor. Heartworm is a horrible disease, and Colin gets a pill every month, 12 months a year. She gave him the last pill on the first of this month and asked me to order more. The problem is, Novartis has had some severe problems at the factory, starting last January, and Interceptor is no longer available and may not be available for several months.

There are alternatives, of course, but none of them are good. Except for one thing, the best alternative would be HeartGard Plus, which costs around $72 for a 12-month supply. That one thing is a showstopper, though. The active ingredient in HeartGard is ivermectin, which can kill some Border Collies as well as some other herding breeds. The problem is a mutation in the MDR1 gene. We don’t know if Colin has that mutation and, if so, whether it’s heterozygous or homozygous.

The other alternatives are much more expensive, twice to three times as much as the HeartGard. But that’s the least of the problem. The real issue is that their active ingredients are also avermectin-class drugs, albeit not ivermectin. And the multidrug sensitivity caused by the MDR1 mutation includes all of the avermectins. Fortunately, there’s a genetic test available from Washington State University. I just requested the test kit. All we have to do is get scrapings of Colin’s squamous epithelial cheek cells, send them back to WSU, and pay them $70. They’ll tell us if Colin has the MDR1 mutation and, if so, whether it’s heterozygous or homozygous.

07:52 – It wasn’t as minor as we’d hoped. Barbara’s dad had a bad fall yesterday afternoon about 1400. No one notified Barbara for almost an hour. She and her mom and sister spent the next eight hours or so at the emergency room, before they finally admitted her dad at least for overnight. Barbara finally got home at midnight. Her dad is okay for now. They ruled out a stroke or TIA. At this point, they think a cardiac arrhythmia caused her dad to lose consciousness momentarily and fall. The hospital was actually ready to release her dad last night, but Barbara told them she wasn’t comfortable taking him home in his current state. He was still having trouble breathing and showing signs of CHF. So they’re keeping an eye on him for a while until they’re sure it’s safe for him to go home.

10:38 – I no longer have a cell phone. When I called Barbara on her cell phone yesterday, I thought I’d better check the balance on her Boost Mobile prepaid cell phone. So I went over to the Boost Mobile web site and logged in. Sure enough, she was down to something like $8. Then I noticed something strange on her account page. The call I’d just made to her had been charged at $0.75. That was really strange, considering that Boost Mobile bills in one-minute increments and Barbara has a flat $0.10/minute rate. So how could a call cost $0.75? As it turns out, it was a three-minute call, but Boost Mobile increased their prices as of yesterday from $0.10/minute to $0.25/minute. Geez.

So I decided just to give Barbara my PlatinumTel prepaid phone, which costs only $0.05/minute and just order another one for myself. The trouble was, they had only four phone models on offer, and none of them were clamshells. I carry a cell phone in my pants pocket, which means I really need a clamshell model. Oh, well. I’ll just wait until they have more models in stock. For now, I’ll do without.

As it turns out, BoostMobile is “encouraging” people with iDEN phones to buy new phones. BM still has something like a million iDEN users, and Sprint is in the process of shutting down their iDEN network. Apparently, they’ve already shut down thousands of iDEN towers nationwide (which explains why Barbara has had problems with spotty service availability for the last few months) and they plan to shut down the network completely as of next June. It was time for Barbara to get a different phone anyway. She wanted a clamshell model too, so I just gave her mine. So today she’s giving her new cell phone number to her sister and parents, who were the only ones who had the old one. Once she does that and clears any current voicemail, she’ll just shut down her old phone and let it die when the time expires.

07:23 – The big news story is that Britney Spears apparently has leprosy. In other news, it looks like we’re in for four more years of complete gridlock, which is a good thing, considering the alternative.


09:34 – Hmmm. Barbara’s only comment this morning on the election results was that she wants to move to Canada.


09:59 – We’re down to just one biology kit in stock, so I’ll build another 15 today. That’s verbal shorthand, of course. I won’t actually be building those kits myself. Obama will be building them for me. Bastard.


16:04 – Barbara called from work a little while ago to say that her dad had fallen and she was on her way to meet them at the emergency room. She thinks he’ll be okay, but falls are dangerous at any age, let alone 90. I’ve said this to Barbara before, and I hate to annoy her by repeating myself, but her dad really, really needs to be using a full walker instead of just a cane. He’s no longer strong enough or fast enough to catch himself with just a cane. I’m sure he’ll resist using a walker, but I don’t see any alternative.

09:39 – I was able to talk Barbara into taking it easy this weekend. Right now, while I do laundry, she’s down cleaning out the basement. Then she’ll clean the upstairs, blow leaves, and then head out to plow and plant the back 40. Then, after lunch, we’ll work on kit stuff.

We’ve started getting a few political calls again, two or three a day, all from the Republicans. I got an automated poll call the other day. I agreed to take it, just for fun. The first question was about my age. I pressed one for 18 or under. Then it asked if I had already voted. I pressed one for yes. Then it asked if I’d voted for Obama, Romney, or another candidate. I pressed one for Obama. I do so enjoy doing my bit to screw up polls.


11:32 – Ben Franklin is probably spinning in his grave. Barbara reminds me that the time changes again at 0200 tomorrow. It really pisses me off. Eight months ago, the government “borrowed” an hour from me. Of course, “borrowing” at gunpoint is usually called armed robbery. Now, months later, they’re finally going to repay it, with with zero interest. That’s right, they stole 3600 seconds from me, and early tomorrow morning they’re going to give back only 3,600 seconds. Bastards. I hope they all die slowly and in agony.
