09:50 – We received orders for two chemistry kits and one biology kit this morning, which took us down to zero inventory on both kits. Fortunately we now have everything in stock we need to assemble 30 more of each.

Barbara spent yesterday afternoon watching Grey’s Anatomy on Netflix streaming while she sealed 30 sets of the regulated chemicals for the chemistry kits and then labeled another set of bottles for 30 more chemistry kits. That’s plenty to keep me busy for a while. She wanted to get ahead of me so that she can take the Thanksgiving weekend off from doing kit stuff and put up the Saturnalia tree and decorations. Bob the illuminated penguin is already out on the front porch.

While Barbara was labeling bottles yesterday, I had to open our last case of 1,100 15 mL bottles, so this morning I’m cutting a PO to order about 7,000 more 15 mL and 30 mL bottles and caps. I’m still ordering by the case, which is 1,100 of the 15 mL bottles or 1,500 of the 30 mL bottles. I though about ordering in bulk, but that would mean ordering 10,000 to 20,000 of each size, they’d arrive on a pallet rather than in large cardboard boxes, and the cost is only 2 or 3 cents less per bottle. So for now we’ll stick with ordering cases.

07:14 – I had an interesting conversation with our mailman yesterday. I commented on the $15+ billion loss the USPS had just reported, and he commented that much of that was because of the $11+ billion USPS is forced to pay to fund health care for future retirees, something that no other federal agency does. I said that in the long run it didn’t really matter because none of us were ever going to see the pensions and retirement health care that we were supposedly paying for now. He agreed completely and commented that he thought it was time to start stocking up on canned food. I said, “We already are,” and he replied that he and his wife were as well.

Over the weekend, we’ll build another 30 chemistry kits and another 30 biology kits for inventory. Although sales are much slower now than they were in August/September, slow is relative. So far this week, we’ve sold two forensic science kits, two biology kits, and four chemistry kits. We’re still in good shape on forensic science kits, but we’re down to only three chemistry kits and two biology kits in stock.


10:12 – I just finished making up the last chemical but one for the chemistry kits. (That one is starch indicator solution, which I make up in the kitchen rather than the lab.) As usual, I waited until last to make up the hazardous/obnoxious chemicals, finishing up with 6 M sodium hydroxide, which’ll dissolve a glass stirring rod if I’m not careful. So, today I’ll fill and cap the final six or eight sets of 30 bottles for the chemistry kits. I’ll leave the sealing to Barbara. She likes to shrink the cap bands on the 30 mL bottles of regulated chemicals with the heat gun.

As always, I feel a bit hypocritical when I’m working with chemicals for the kits. I always wear splash goggles, of course, but I don’t wear gloves for any of them. Having concentrated bases or acids contact my hands doesn’t really worry me. If it happens, I just rinse the stuff off with cold water. I do draw the line at concentrated hydrochloric, nitric, and sulfuric acids, though. Those I’ll handle without gloves. But anything much more hazardous/corrosive than those I’ll wear gloves for, if not double gloves.


15:46 – Barbara is leaving work an hour or so early this afternoon to go run errands and then have dinner with her parents and a couple of friends. I just finished the last set of bottles for the chemistry kits. We now have 30 of each chemical and 60 of several. So I decided to knock off early, too, and watch some more Heartland reruns.

When I started watching Heartland reruns yesterday, I noticed that Netflix streaming was showing 67 episodes. That’s 13 episodes from series one and 18 episodes each from series two, three, and four. Until yesterday they had only 45 episodes available: all of series one and two and the first 14 episodes of series 3. But then I checked the Netflix website, which is still claiming to have only those 45 episodes. Oh, well. I prefer to watch streaming, but I have series three, four, and five on disc.

08:00 – ObamaCare strikes. The top headline in our paper this morning was “Wake Forest Baptist Medical Center Cuts 950 Jobs“. The spokesman made a point of saying that the cuts were preemptive, and not a result of any financial difficulties. WFU/BMC is preparing itself for the new economic realities. As the article pointed out, we can expect to see similar cuts at other hospitals across the state and the nation.

That’s just the beginning of the destructive and distorting effects that ObamaCare will have on our economy and our society. I have many acquaintances who own small businesses, and several of them have told me that they’ll be making changes to minimize the effects of ObamaCare on themselves and their companies. These range from shifting away from using all full-time employees toward temporary/part-time/contract labor to cutting payrolls to get under the 50-employee statutory minimum to splitting their companies into two or three smaller companies. Two or three that currently provide health insurance have said that they plan to eliminate it because it’ll be cheaper to pay the annual fine than to continue to pay health insurance premiums. One thing is sure: ObamaCare is going to hurt small businesses and their employees.


10:04 – Well, that was interesting. They’re still re-roofing the house across the street. Colin is terrified of popping and banging sounds, so I’ve been taking him downstairs and out the back door.

The instant we went out the back door, Colin froze in his alert position. I followed his sight line and saw what I at first thought was a stray dog down in the corner of our back yard. But Colin wasn’t barking frantically, as he would if there was another dog in his yard. Instead, he froze and snarled. Let me tell you, Colin has an absolutely vicious-looking set of fangs and a low, rumbling growl that should scare anything.

It was a coyote, of course, and it quickly decided that discretion was the better part of valor. I could just see what was running through its mind in the instant before it turned and ran for its life. “Holy Shit! That thing is twice my size and its ears stick straight up. WOLLLLLFFF!”


11:31 – Well, crap. I just finished making up three liters of IKI (iodine/potassium iodide) solution for the kits. I make this solution and many others up in gallon orange juice bottles that Barbara provides me at a rate of about one a week. So, I just finished making up the three liters of IKI when I realized that I’d need to transfer it to glass bottles because the IKI penetrates the orange juice bottles if it’s left in them for more than a few days. So off I went in search of six 500 mL glass bottles with cone liners. I found six of them, all already filled with IKI solution. So now I have six liters of IKI, which is enough for about 200 kits. Oh, well. The stuff keeps forever, and fortunately I have many spare glass bottles to transfer it to.

09:00 – UPS showed up yesterday with a partial shipment from one of our wholesalers. This was mainly small stuff that we were running short of. Fifteen dozen each of the 10 mL graduated cylinders, 15 cm plastic rulers, and 12″ lab thermometers. Oh, and a case of glass Petri dishes for the life science kits. The rest of the order is chemicals, which haven’t shipped yet.

Poor Colin. He’s terrified of banging noises, and they’re replacing the roof on the house across the street. He cringes each time he hears a pop or bang, so he’ll be doing a lot of cringing today. He’ll probably also have an accident or two in the house, because I can’t convince him to go outside.

09:24 – We did a Costco run and dinner with Mary and Paul yesterday. Neither of us needed very much, so it was a short run. We picked up a fresh supply of Coke for me, a couple of things I needed for kits, some stuff Barbara needed, and an extra couple or three weeks worth of canned food.

I can make a good excuse for my incorrect prediction that Romney was going to win in a landslide. Around here, it sure felt like the Democrats were in deep trouble. While the Democrats made gains or at least broke even in most of the other 49 states, North Carolina turned sharply right. This was the only battleground state won by Romney, but that was the least of it. We elected a Republican governor, replaced several Democrat US representatives with Republicans, and flooded the North Carolina house and senate with Republicans–it’s now almost 2:1–giving the Republicans a veto-proof majority in both houses. Republicans also dominated the other statewide races and at the city and county levels. Finally, the Republicans control the state supreme court, all of which makes North Carolina among the reddest of the red states. Don’t expect gay marriage or marijuana to be legalized here.

Meanwhile, the North Carolina government is busy burning down our nearest state park. They started an (un)controlled burn on Thursday at Pilot Mountain state park, intending to burn less than 200 acres. The fire has now burned more than 800 acres and is still not under control. It’s supposed to rain this evening and tomorrow, so perhaps that’ll help.

I’m working on kit stuff.


10:56 – Hmmm. The fustercluck in Greece continues, with no resolution in sight. Basically, the problem is that Greece is completely bankrupt, with huge outstanding debts, and no one wants to pay for them. The Troika–the EU, the ECB, and the IMF–are now bitterly divided on this issue. The IMF insists that it will not kick in any more money until Greece’s debt is somehow made “sustainable”. Meanwhile, the EU and ECB categorically refuse to take losses on the Greek debt they hold because their electorates, primarily the German people, would crucify them for doing so. So, the situation as of now is that the IMF is refusing further funds and the EU/ECB is refusing further funds. Neither of them is willing to budge.

The IMF has the whip hand. Their debt is senior to that held by the EU and ECB. So, at this point, the most likely outcome is that the IMF will walk away, leaving the EU and ECB holding the bag. The EU and the ECB are unlikely to throw good money after bad. It seems likely that the Greek debt that comes due this week will be paid off by an accounting trick. The ECB can allow Greek banks to increase the percentage of Greek bonds on their books, allowing the Greek banks to purchase the worthless bonds that Greece will issue to rollover those coming due. But in reality that translates to the ECB lending Greek banks yet more money that will never be repaid, so the question for Germany becomes whether it’s worth throwing away a few billion more euros to buy just a little more time. That’s the same situation Germany has been facing, and so far they’ve decided to throw away the money each time the situation has arisen. What Germany (Merkel) really wants is to put off the crash until she runs for reelection next autumn, but that’s becoming increasingly costly. So it wouldn’t surprise me if Merkel finally decided to bite the bullet and say enough is enough. If that happens, Greece goes completely belly up this week. If Merkel decides to pay one more time, Greece will totter on for a few more weeks.

Here in the US we have the upcoming so-called “fiscal cliff”, which the MSM describe as moderate tax increases coupled with dramatic spending cuts. In fact, it’s no such thing. It’s large tax increases coupled with spending increases that will be smaller than they might otherwise have been. No one, including the Republicans, is talking about actual cuts in spending. Why bother. They’ve dug us into a hole so deep that there’s no getting out of it. Might as well just continue digging. Our economy can’t get deader than dead.

The government figures on debt are even less trustworthy than their figures on inflation. I don’t even bother to keep track of what the government claims our debt is. Something like $17 trillion IIRC. In reality, as I’ve said before, if you calculate our debt honestly, including off-budget items, unfunded commitments, and realistic demographics and NPVs, our actual debt at all levels must exceed $100 trillion. I’ve seen credible figures claiming it’s well over $200 trillion. As Everett Dirksen famously said, “a billion here, a billion there, pretty soon you’re talking about real money”. And we’re talking about debt levels four or five magnitudes higher. A billion dollars is more than $3 for every US citizen, man, woman, and child. A trillion dollars is $3,000 each. The $17 trillion the federal government admits to is more than $51,000 each. The real debt is almost certainly at least $300,000 per citizen and may be twice that. The obvious outcome is that those unfunded commitments aren’t going to be honored. Or they’ll be honored at face value with grossly inflated dollars. Either way, it’s not going to be pretty.

I’m working on kit stuff.


14:26 – For those of you who don’t read the comments…

It all makes sense now: Gay marriage legalized on the same day as marijuana makes perfect biblical sense. Leviticus 20:13: “A man who lays with another man should be stoned.” Our interpretation has just been wrong for all these years.

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.

07:23 – 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.

09:43 – CNN and the other left-leaning news sources seem to agree that the race is now a dead heat, which tells me that Obama must be lagging badly. On Wednesday, I’ll check the election results with the same enthusiasm I have for checking the results of the Super Bowl or World Series. Which is to say none.

I’m still working on building more of the current kits, but most of my time recently has been devoted to designing and prototyping a couple of new kits and writing the manuals for them. One of those is the LK01 Life Science kit, which we intend to make available in early 2013. The contents of that kit are semi-finalized. There may be minor adds or deletes as I write and do the lab sessions, but no major changes. One change I made from the biology kits is going from a sleeve of 10 sterile plastic Petri dishes in the Biology kit to a pair of glass Petri dishes in the Life Science kit. Two glass Petri dishes actually cost more than a sleeve of 10 plastic ones, but they also occupy a lot less cubic. I’m striving to make the Life Science kit fit the smaller Regional Rate Box A rather than the Regional Rate Box B we use for the Biology kit. The difference in shipping cost is significant, maybe $4 on average, as is the amount of space needed to store finished-goods inventory. So I just ordered a case of the glass Petri dishes. They require extra care in packing, but we can deal with that.

I also ordered some chemicals, both for the new kits and for the current ones. For the first time, I ordered some liquids in 2.5 L bottles rather than 500 mL or 1 L bottles. The cost is much lower in 2.5 L bottles. For example, I ordered one 2.5 L bottle of reagent-grade 28% ammonia for about $22 plus shipping. That amount in smaller bottles would have cost about twice that. In the past, I’ve avoided ordering the larger bottles simply to conserve storage space, but the lower unit costs of the larger bottles are becoming compelling.

07:54 – We have only one episode left to watch in series five of Gossip Girl. Series six, the final season, is running now, and it has only 10 episodes. It’s a real shame to see what this series has become. In series one and two, the writing was excellent and the characters nuanced. Beginning with series three, the writing started to go downhill fast. Series four was bad, but series five is terrible. Ham-handed writing, embarrassingly bad dialog, plots that make no sense at all, and the characters have become cartoonish. It’s a waste of a good cast, particularly Leighton Meester and Ed Westwick, who’ve shown themselves to be the finest actors in the cast. If it were just me, I’d have given up a couple episodes into series three, but Barbara likes to see things through to the end. She’s loyal to series she once liked. I’m not. I’d much rather watch reruns of an excellent series than new episodes of a bad one.

I’m still working on the new batches of biology and chemistry kits, as well as writing the manual for our next kit.


16:01 – There’s nothing like a natural disaster to remind us that a large percentage of Americans are apparently morons. I was just reading an article about items in short supply in the affected areas. People paying $5 each for D cells or waiting in mile-long lines to buy gasoline. I can just imagine the thoughts that must go through whatever these people use to substitute for brains: “Duh. The storm has passed, duh. The area is devastated, duh. I guess I better go out and buy some food and water and flashlights and batteries and gasoline, now that they’re no longer available. Duh.”

I mean, how much foresight does it take to realize, particularly when a massive storm has been forecast several days ahead of its expected arrival, to make sure you have sufficient supplies to weather that storm? How much foresight is needed to realize that the power may fail, or that it might be a good idea to fill your car’s fuel tank? I used to think that these people couldn’t possibly be as stupid as they seemed to be. Then I realized, Occam’s Razor. Yeah, they really are that stupid. And, come Tuesday, they’ll not merely be permitted to vote. They’ll be encouraged to vote. And people wonder why things are such a mess. Geez.
