08:18 – Yesterday we finished up the chemicals for the next batch of 30 biology kits and 30 life science kits. That’s good, but it’s time to change gears, because this morning we got an order for the last chemistry kit we have in stock. Fortunately, we have everything we need to box up another batch of 15 chemistry kits. So, today while Barbara is over finishing cleaning out her parents’ house, I’ll be making up those 15 chemistry kits.

Of course, that also means we’re about to run dry on chemistry kits, so I’ll also get started today on running labels, cutting POs, and other preparations for another batch of 30 chemistry kits. Or maybe 60. Lather, rinse, repeat.


16:52 – It’s fortunate that I got more chemistry kits built, because I just got another order, which took the inventory status on the chemistry kits from zero to -1. (I hadn’t actually done the final boxing up on the 15 kits, so I rushed downstairs and boxed one up to ready it for shipping.) Tomorrow is soon enough to get the other 14 boxed up and ready to ship.

09:16 – I’ve just set a new policy. If the USPS loses a package, I’m not going to waste any time trying to resolve the issue with USPS. I’ll just write it off and ship a replacement. It happens seldom enough–a small fraction of one percent in our case so far–that it’s just not worth wasting time to get a determination, which I’m told is almost always “we lost it; tough luck”. Even at that, it’s still much cheaper to ship USPS than to use UPS or FedEx. The packages get to their destinations in one to three days, and we’ve had very little shipping damage. So, I conclude that USPS can be very annoying, but they’re still by far our best option.

We’re just about finished packaging chemicals for a batch of 30 biology kits. We’ve also done 30 sets of the chemicals that (so far) will be included in the Life Science kits, which are a subset of those in the biology kits. All of those chemicals–stains and so on–have essentially unlimited shelf lives, so there was no downside to making them up now. In fact, like wines, some stains actually improve with age.

Back when I was a teenager, I couldn’t afford a good microscope. Back then, even student models were extremely expensive, probably the equivalent of $1,500 or more in today’s dollars. One of my parents’ friends gave me a WWI-era Zeiss microscope. I wish I still had it. I think it was probably produced for the German military. It came in a beautiful fitted wooden case that also included an assortment of accessories, including several stains. I remember thinking at the time that there was no way the stains could possibly still be good, since they were at least 50 years old. A couple of the bottles were empty or had dried out, but there were three or four that looked untouched. So I tried them, and they worked very well.


11:26 – This latest EU summit, like all of the other 20-odd EU summits since the beginning of the euro crisis, accomplished essentially nothing. The position of Greece, Spain, Italy, and the other spendthrift states remains unchanged: “We want Germany to pay all of our debts and continue to subsidize our irresponsible spending. Oh, yeah, and Germany can’t dictate terms to us. Just give us the money.” And Germany’s position also remains unchanged: “We’re fed up with paying everyone’s debts. We just want to get out of this mess as cheaply as possible. Ask us for anything other than more money.”

It seems that Rajoy and Spain are finally beginning to realize they’re not going to get the bailout-that-can’t-be-called-a-bailout. If Spain wants to beg money from the ECB and the ESM, they’re going to have to do so explicitly and accept whatever terms Germany insists on. Doing that would finish Rajoy politically, and he knows it. Rajoy is between the proverbial rock and hard place. He’s already made veiled threats to exit the euro, which would inevitably also mean exiting the EU. Spain’s debt for 2012 is essentially all sold already, but Spain is in deep trouble in 2013, when it has to sell hundreds of billions of euros of debt. Spain has zero prospect of doing this at all, let alone affordably, which means Spain is almost certain to default on a massive scale in 2013. Either that, or leave the euro, which amounts to the same thing. Creditors will no doubt be paid back in worthless local currency, artificially pegged to the euro at 1:1.

07:59 – We use 30 mL wide-mouth “pharmaceutical packer” bottles for some of the solid chemicals in our science kits. One of those is dextrose. Back when we filled the first batch of those bottles, I tested them to see how much dextrose would fit in one of the bottles. It turned out that loose-filling the bottles to the rim put about 26 or 26.5 grams, give or take, but always at least 25 grams. So I made the labels to list the contents as 25 grams.

So yesterday I started filling a batch of 60 bottles with dextrose. The first 20 or so were no problem. I was using dextrose from a current batch. Then I opened a new 3 kilo bottle of dextrose, loose-filled a bottle, and found that it contained only about 20 grams. The new batch of dextrose is fluffier than the old batch. I tried tapping the bottle to settle the contents, but even with tapping there was no way to fit 25 grams into that bottle. So now I have to use a thick rod to press down the contents of the bottle, refill it to the rim, press down again, and refill yet again to the rim. I guess they don’t call these “packers” for nothing. I guess I should just re-label the bottles as containing 20 grams rather than 25 grams, but I’m stubborn.

Oh, and I got a call yesterday evening from a USPS rep about my lost Priority Mail packages. It turned out that she wasn’t the proper person to handle the problem, so she said she’d refer it to the proper person, whom I’d hear from in the next 24 hours.


15:05 – I just took Colin for a walk. There are hundreds of squirrels in our immediate neighborhood, and Colin is a Mighty Squirrel Hunter. Or he would be, if he didn’t have me along. I honestly believe he could keep himself fed just on squirrels, if it weren’t for me holding the leash. Colin, on the other hand, probably wonders why I didn’t starve to death long ago. Here is Colin’s evaluation of my hunting skills:

Spotting prey: D-

Stalking prey: F

Chasing prey: F

Pouncing prey: F

Sharing prey: B+

That last one is the only reason he tolerates me. Not only do I share with Colin the prey that Barbara brings home from the supermarket, but I have access to tasty prey that’s hard to find in the yards around the neighborhood, things like Cheesoritos and beef-flavored chews.

11:48 – My morning has been eaten by carnivorous gerbils. First, I got email from a customer to whom I’d shipped a kit on 9 October with an expected delivery date of 11 October. The kit hasn’t arrived yet, so I spent the better part of an hour trying to find out what’s going on. I finally got through to someone at USPS who knew how to get an investigation started. The kit arrived at the Greensboro sorting facility, but as far as anyone can tell it’s still there. Then I spent some more time on the phone with the insurance company that we’re trying to get a policy with to insure Barbara’s parents’ house. Apparently, no insurance company licensed in North Carolina is willing to insure unoccupied dwellings, so we’re having to deal with an out-of-state company. At least I think everything is resolved there.

10:20 – Work on the new batch of biology kits is proceeding apace, but we’re now down to just two chemistry kits in stock. Fortunately, we have everything we need to build 15 more quickly, but then the well runs dry. So, as soon as we finish this batch of 30 biology kits, we’ll start on another batch of 30 chemistry kits. The chemistry kits outsell the biology kits about 1.5:1, and kit sales have slowed seasonally, so the new batches should last us at least a month, if not through the end of November. Of course, starting in late November, kit sales tend to pick up for Christmas and second semester, so we’ll need to get more in the queue.

It’s difficult to see how things in the eurozone could be much worse on the eve of the first full EU summit since June. French and German leaders always hate each other, and Hollande and Merkel are no different. The difference this time is that they’re not keeping it private. Ordinarily, the French and German leaders meet on the eve of an EU summit and essentially agree on the agenda and decisions ahead of time. This time, Merkel and Hollande are in disagreement on everything, and are tossing public barbs at each other. The Greek talks with the Troika have collapsed entirely, with Greece saying there’s no way it’ll agree to the Troika terms. That means Greece runs completely out of money in the next six weeks, with no prospect of getting any anywhere. The markets are closed to them, the IMF won’t bail them out, and the EU won’t bail them out. That means Greece will default, not just on bonds but on public salaries and pensions and payments to the companies that are importing desperately needed food and medicines, or were importing them until they stopped getting paid. Meanwhile, as its price for continuing to support any EU bailouts, Germany is apparently now insisting on an EU fiscal overlord, which simply isn’t going to be accepted by other EU members. Obviously, Germany has already decided that enough is enough, but instead of just saying “nein” explicitly, they’re setting conditions that they know will never be accepted. That way, Germany can at least say “we tried” when the whole pathetic euro edifice collapses.


14:46 – Oh, wait. The Troika and the Greeks have kissed and made up. (Now there’s a disgusting image…) Greece says it’s going to get the long-delayed bail-out tranche in time to avoid catastrophe. The Troika says they and the Greek government have agreed on “broad outlines” of the terms needed to allow the bail-out to go ahead, albeit without additional IMF funds. The truth is, the IMF, the EU, and the ECB are all terrified at what’s going to happen when-not-if Greece collapses. When they talk about contagion from a Greek collapse being “containable”, they’re whistling past the graveyard, and they know it. Of course, as they say, the devil is in the details, and it wouldn’t surprise me if this latest deal, like so many others, collapses as a result of those little details. Yet one more attempt to buy time with smoke and mirrors. The trouble is, they’re running out of time. And smoke and mirrors.

07:33 – I see that other drugs sold by NECC are now suspected of harming patients to whom they were administered.

Yesterday, I was making up a liter of 0.5% aqueous eosin Y stain. I tapped out about 5 grams of the stain into a tared beaker sitting on the scale. I actually ended up with 5.23 grams in the beaker. Close enough. I added 800 mL or so of hot water to the beaker, stirred to dissolve the powder, transferred the solution to a rinsed-out one liter soda bottle, and brought the volume up to one liter. Because fungus tends to grow in a plain eosin Y solution, I added a small spatula spoon of thymol crystals as a preservative, capped the bottle, swirled to dissolve the thymol, and set the bottle aside.

As I was doing all that, it occurred to me that that stain solution, not intended for human consumption and made up without using aseptic procedures and with no attempt to maintain sterility, was probably actually safer for human consumption than the products made by NECC. At least I added a preservative to prevent fungus growth. How pathetic is that?

If the news reports are to be believed, NECC produced products that they marketed as suitable for injection into humans, and they did so without following even basic aseptic precautions. If that’s in fact true, the owners and managers of that business should be facing serious prison time. So far, 15 people have died as a direct result of being injected with those products, and some 15,000 others are at risk. That may not qualify legally as first-degree murder, but it must certainly qualify as reckless homicide.


12:01 – I just spotted Heather, Amy’s step-mom, while I was out walking Colin. I told Heather that Barbara and I really didn’t want any magazines, but we wanted to support Amy. I asked if we could just donate cash to the school fundraiser, and Heather said sure. So I handed her a $20 bill.

I actually almost handed Amy some cash when she rang our doorbell selling magazines. Fortunately, I remembered what happened with Jasmine. On her birthday, maybe her 15th or 16th, I tried to give Jas $20 to buy herself some iTunes tracks or something. She thanked me, but said she wasn’t allowed to accept money from men. Ruh-roh. It never even occurred to me that that might be a problem. I talked to Kim later. She said she trusted me and had no problem with me giving Jas cash for her birthday, but Mary, Jas’s grandmother, had a big problem with any man, including family members, doing so. And, sad to say, I think Mary is right. What a world we live in.


16:33 – I just made up a liter of methyl cellulose solution. Well, actually, it’s still a suspension, but it’ll soon be a solution. Methyl cellulose has an interesting property. It’s soluble in cold water, but insoluble in hot water.

You might think I could make up a solution by stirring methyl cellulose powder into cold water. Unfortunately, that doesn’t work. Methyl cellulose has high surface tension, which means water has a hard time wetting it. Trying to stir the powder into cold water produces globules of methyl cellulose that have slimy wet outer surfaces and dry methyl cellulose powder inside. It makes a real mess. So the trick is to stir the methyl cellulose powder into very hot water. The hot water doesn’t dissolve the powder, but stirring disperses it into a suspension of fine powder. Cooling that liquid suspension in an ice bath or the freezer allows the methyl cellulose to go into solution without clumping. So I have a liter sitting in the freezer as I write this.

09:28 – Interesting article on CNN about how countries compare in paid holidays. The UK leads the pack, with 28 statutory paid holidays. The US comes in dead last, with zero statutory paid holidays, although, as the article points out, US companies typically voluntarily provide about 15 paid holidays per year.

Americans also typically take many fewer vacation and sick days than Europeans do. Back when Barbara and I were first married, her dad introduced us to a young woman who’d just moved here from the UK, where she’d been a radiation therapist. She was being paid literally two or three times what she’d earned in the UK, but she was stunned to learn that her paid time off was a tiny fraction of what it’d been in the UK. In addition to having half as many paid holidays here, she was very surprised to learn that she got only two weeks’ paid vacation, versus the six weeks she’d had in the UK. She was also surprised to find that many Americans, then as now, didn’t even take off all the days they were entitled to.


Work on the science kits continues. Now that we’re in a slower time we’re trying to build inventory. Although it’s nothing like the flood of orders in July through September, there’ll be another mini-peak from mid- to late-November through mid-January as people buy science kits for Christmas and the second semester.


14:19 – The other night when I thought I spotted an Indy car cruising down our street I was right, kind of. It was a replica 1989 Lola Indy car. I was also right about it having a serious engine compared to the Honda 4-cylinder of the replica Can Am car I spotted a year or so ago. The replica Lola has a Chevy LT1. Both cars are street legal. Colin and I spotted them during our walk a little while ago, and I talked to guy who built them.

08:19 – With three weeks left until the election, both campaigns are starting the final push. I don’t know how it is in other, non-swing states, but here we’re being subjected to a barrage of campaign phone calls and fliers. I’ve been averaging a couple phone calls a day from the presidential campaigns, and that doesn’t count the ones from the campaigns for state and local offices. I can’t wait for this to be over.


09:36 – I need to make up two liters of Benedict’s qualitative solution. I have the 34.6 grams of copper(II) sulfate and 346 grams of sodium citrate I need, but I just realized that I’m fresh out of sodium carbonate. So I just put a kilo or so of sodium bicarbonate in a glass baking dish and stuck it in the oven at 450F. At that temperature, two molecules of sodium bicarbonate quickly decompose into one molecule each of sodium carbonate, carbon dioxide, and water. In half an hour or so, I’ll have a baking dish full of pure anhydrous sodium carbonate.

08:49 – I just watched the original video posted by Amanda Todd, the 15-year-old Canadian girl who killed herself after being tortured on Facebook and physically assaulted, all because as a seventh grader she made the mistake of flashing her boobs on a webcam video.

Apparently no one–not her family, not her friends, not her teachers, no one–was able to help this girl. When I read the news story, I went over to Google Images to see what the girl looked like. That’s where this image came from. And among the top image results was one that was truly nauseating: a post from 4chan asking if anyone had the picture of Amanda’s boobs. Jesus.


14:55 – While I was walking Colin earlier today, I stopped to speak with one of the neighbors. He asked me who I thought was likely to win the coming election. I told him that unless something changes drastically, I expect Romney to win in a landslide. I’ll be surprised if Obama wins 221 electoral votes, let alone 271. And I suspect that’s what’s going to happen for the same reason that Obama won last time. Few people actually supported Obama’s ideas, to the extent he had any. They were voting for Obama as not-Bush, and this time I suspect people will vote for Romney as not-Obama.

People understand that things are bad in this country and that Obama hasn’t done anything to make them better. I think people will vote for a change, even though many are aware they’re really just voting for the same-old same-old. Still, given only two realistic choices, I think they’ll pick the not-Obama one.

North Carolina is supposedly a “swing state”, but I don’t sense that locally. I see many fewer Obama signs now than I saw four years ago, and if Obama loses North Carolina’s cities he has no chance to win the state. Rural North Carolina will vote overwhelmingly Republican. I suspect the same is true in the other so-called swing states as well. Obama’s liberal constituency, blacks, labor union members, and so on will vote for Obama, no matter what. The religious right and most of those who are well off will vote for Romney, no matter what. But I think those in the middle, the ones who don’t particularly want to vote for either candidate, will vote for Romney simply because he’s not-Obama. We’ll see.

09:30 – We didn’t watch the vice-presidential debate last night, but, from all accounts I’ve read, Ryan won despite being outnumbered two to one. Instead of wasting time watching that, we chose to waste time watching the final four episodes of the final season of Despicable Housewives on Netflix streaming.

Speaking of despicable, the school fund-raisers are at it again. One of the neighborhood girls stopped by trying to sell magazines for her school fund-raiser. What possesses people to put 14-year-old girls in this position, not to mention putting their neighbors in that position? I almost told her that no one wants these overpriced magazines. No one. I’d rather just hand her money. In fact, they need to stop sending these kids out to raise money, period. What kind of lesson are they teaching them? We pay federal, state, and local taxes to support the schools. The kids shouldn’t be forced to raise more money themselves by begging from their neighbors. It’s demeaning.


13:03 – Boy, am I not going to do business with U-Line. Back before we started the business, I ordered some stuff from them: shipping boxes, bubble-wrap, shrink-seals, and so on. I remember thinking at the time that their prices were a bit lower than local suppliers, but their shipping charges were outrageous. If there’s one thing customers really, really hate, it’s when a vendor attempts to making shipping a profit center.

So, this morning I got email from someone who wanted to know if we’d sell him just the six stains in the biology kit. Sure, why not? So I quoted him a price. All of those stains will fit in a USPS Priority Mail small flat rate box, which costs $5.15 to send anywhere in the US.

But I got to thinking. First-class mail is a very good deal for light packages, although it’s available only for packages that weigh 13 ounces or less. Those half-dozen stains would weigh well under 13 ounces, so I went to the USPS web site to check out how much first-class mail would cost. Even a 13-ounce package costs only $3.65, and it’s more likely this package would weigh maybe 6 ounces, which is $2.46 worth. Just as interesting to me is that I could send that package to a Canadian address for less than $5, versus the $30+ it costs to send it to Canada using Priority Mail International.

Just two problems. First, the USPS web site allows me to print postage labels for Express or Priority Mail, but not for First-Class mail. How strange is that? I guess they’re trying to keep the local post offices in business or something. Well, there is one alternative. Rather than using their web site to produce the postage labels, I could download and install an application that does the same thing, but allows me to print first-class, parcel post, and other postage labels. The only problem with that is that it won’t install under WINE, so I’d need to run an actual Windows box. Either that, or perhaps Virtual Box. The other problem, of course, is suitable boxes. The boxes that USPS provides are for use only with Express Mail or Priority Mail, NOT with first-class mail.

So I went over to the Uline site and found suitable boxes. I was going to order two sizes, one about the size of a DVD writer and a second about twice that size. They had those boxes for $0.42 each and $0.44 each, with a minimum order of one carton of 50. So I added one carton of each size to my shopping cart, for a total of $21 plus $22 or $43. Note that these boxes are, small, light, and are shipped flat, so this wouldn’t have been a bulky or heavy shipment. Uline offered me only one shipping option, UPS ground. Obviously they would ship from a warehouse not far from us, because they said delivery would take one business day even UPS Ground. Their shipping charge? About $21, or nearly 50% of the order amount. So, assuming that perhaps there was a minimum shipping charge that made that charge so high, I added another box of boxes for $21. That took me from $43 to $64 for the merchandise. It also boosted the shipping charge from about $21 to about $32. Once again, they were charging me about 50% of the merchandise total for shipping. So, I’ve written off Uline as a vendor. I’ll get what I need locally.
