09:00 – I do wish the USPS would stop “improving” its Click-N-Ship website. A couple of months ago they changed the input screen for shipments to Canada. There used to be a drop-down list at the top of the form where you had to pick the province. The rest of the fields were all free text-entry fields. Now, you still have to pick the province from the drop-down list at the top and you can then enter free text for the addressee’s name, street address, and so on, but then you get to drop-down list hell. For some reason, you again have to choose the province from a drop-down list. Then, instead of being able to type in the city name, you have to choose it from a (very long) drop-down list of cities/towns in that province. Then, instead of being able to type in the postal code, which in Canada takes the form X9X 9X9, you have to choose it from a drop-down list of postal codes within the city you chose. And it doesn’t provide full postal codes, only the first three bytes, with nowhere to enter the remainder of the postal code.

So, yesterday morning I had a kit to ship to Canada. The address the buyer provided was Toronto, ONT M3A 9X9. So I chose Ontario, followed by Toronto, but “M3A” wasn’t on the list of postal codes. So I searched Google for her full postal code and found out that as far as USPS was concerned it was in North York, a part of the Toronto metro area. So I selected the city name as North York and picked M3A from the drop-down list. When I printed the postage label, the address was in the form “M3A Toronto ONT”. Figuring that M3A wouldn’t suffice, I used a pen to print the full postal code on the label and all three copies of the customs document. Geez.

But at least USPS let me pay for that label without giving me the “Payment method declined…” error message. Same thing around lunchtime, when I ran another batch of labels. Then, mid-afternoon, I tried to print another label for an order I’d just gotten. I was in a hurry because it was almost time for USPS to show up. And, of course, when I tried to pay for that label, I got the dreaded “Payment method declined…” error message. I tried again to pay. No dice. I exited and restarted Firefox and tried to pay again. No dice. I fired up Chrome and tried to pay. No dice. So I restarted Firefox and tried to pay. This time, it worked and I was able to pay for and print the label.

Just as I clicked Print, the phone rang. It was USPS tech support calling, and the guy said it looked like I was having problems printing postage labels. I told him that I was, that this had been going on sporadically since January or February, and that in fact it was going on at the moment and that I’d only just gotten it to work for the label I’d just sent to the printer. The guy said he’d just fixed the problem with my account. I told him that his fix must not have worked because I was just now having the problem. He said he meant literally that he’d just fixed the problem as in two seconds before he dialed my number and that was why I’d just been able to pay for and print the label that I’d just sent to the printer. I thanked him and asked him what I should do if the problem recurred. He said it wouldn’t recur, that he’d permanently fixed the problem with my account, but if I ever did have a problem with Click-N-Ship to call him directly at the number he provided.

08:44 – I was making up chemical bags yesterday when my inventory system failed me. I had one chemical listed as having 80 bottles in stock, but the bin contained only 6 bottles. So, either I removed 74 bottles to build kits and forgot to update the inventory list or I have a large plastic bag somewhere with 74 bottles of that chemical that didn’t make it into the bin. No big deal. If there’s a bag around, it’ll turn up. But I just ran off 120 more labels and will get our stock of that chemical built up again.

Hmmm. Half of Americans don’t want atheist in-laws I don’t blame them. If we had kids, I wouldn’t want them marrying into a family of true religious believers.

07:50 – Amelia Earhart departs Thursday on her attempt to fly around the world. If I believed in fate I’d probably think she was tempting it. Obviously, she’s no more superstitious than I am. I was surprised that she’s chosen to fly a single-engine turboprop rather than something with two engines.

More work on building science kits today.

07:48 – Costco run and dinner with Mary and Paul yesterday. Barbara is headed back to work this morning. Colin’s had a full week of Barbara being gone followed by a weekend with her home, so it may take him a day or two to get used to being back in the routine.

Stock on the CK01B chemistry kits is running low, so I need to build another batch.


10:44 – I just got another big purchase order issued, which should be the last big one I need to do until probably October or November. I wanted to get stocked up before the West Coast dockworkers’ contract expires at the end of this month. There are likely to be major disruptions on products from countries that ship to the West Coast. A lot of the components we use in kits are sourced from India whenever possible and otherwise China. But all of the stuff I’ve ordered was in-stock, and once it arrives we’ll have the components we need to build several hundred more kits.

07:49 – Barbara got home around lunchtime yesterday. Colin and I are both delighted.

Kevlar inventor Stephanie Kwolek dies aged 90. I never met her, although had things been different I might have. One of my junior high school classmates was her niece, Kathy Kwolek. Kathy was close friends with Debby Dailey, who lived two houses up the street from me. They were two of the first girls I noticed as girls. I was interested in both of them, particularly Kathy, who was far prettier than Debby, but both of them were too busy doing teenage girl things to take much notice of me.

More work on science kits today.

08:32 – Barbara gets home this afternoon. Colin and I will be delighted. I need to get things straightened up before she arrives.

I’m making up chemicals for forensic science kits and filling bottles today. I also need to get purchase orders issued for items we’re running short of.

07:55 – Three days down, two to go until Barbara returns home tomorrow evening. I think Colin just figures she’ll be home when she gets here and there’s no use worrying about when that will be.

I see that Obama has F-18’s flying “recon” over Iraq but has ruled out airstrikes. That’s a shame. Airstrikes would be nice, but they should be even-handed so that the US can’t be accused of taking sides. I’m thinking napalm and FAE’s. Lots and lots of napalm and FAE’s. If we obliterate both sides, no one could later claim that we were showing favoritism.


14:51 – Building more forensic science kits has become a high priority. Normally, forensic science kits make up roughly a tenth of total kit sales, so we typically keep only a dozen or so in stock. In the last week, we’ve sold four forensic science kits, which is at least double what I’d expect, particularly with June being a slow month. What’s very odd is that three of those four have gone to Austin, Texas. I wonder if someone is doing a co-op summer science forensics program. Fortunately, Barbara has already labeled 60 sets of bottles for the FK01A kits, and I have most of the solutions already made up. Now I need to make up the four or five solutions I’m short of and get a PO done for some hardware items.

08:14 – Two days down, three to go until Barbara returns home. Colin slept through the night last night. The night before, I think he was expecting Barbara to come home, so he got excited every time he heard a sound that might be her returning. The official high in Winston-Salem yesterday was 92F, but according to both our outdoor thermometers it got to just over 95F here.

Today I’ll continue making up chemicals and filling bottles.

08:18 – One day down, four to go until Barbara returns home. Colin behaved pretty well yesterday, but last night was horrible. On average, every 45 minutes or so he’d jump down off the bed and go roaring down the hall to the front door, barking his head off. I’d just about get back to sleep when he’d do it again.

It’s not yet summer, but things are warming up around here. Our highs for the next week are to be around 95F (35C), with lows in the low 70’s (~ 22C). Thunderstorms are in prospect just about every day.

This morning I need to make up three liters each of Barfoed’s, Benedict’s, and biuret reagents, and 12.5 liters of Fertilizer concentrate A. Once I get those bottles filled, we’ll have all the chemicals we need to make up another 30 biology kits, and most of what we need for 60 or 70 more beyond that. And then I can get to work on making up chemicals for another batch of forensic kits.


15:57 – I just got email from Netflix saying that they’ve (finally) added season five of Heartland. Now they’re only two seasons behind. Speaking of Heartland, I’m now just over halfway through season two. With three evenings left until Barbara returns, I should get through season two and well into season three. I was considering the wild-women-and-parties thing last night, but Colin preferred to watch Heartland re-runs. He really likes hearing Amy say, “Good boy!” He thinks she’s calling him a good boy.

I now have all the chemicals made up for more biology kits. Tomorrow I’ll start on the ones I need for forensic science kits, which we’re getting low on. That includes one of my least favorite chemicals, black fingerprint powder. Our fingerprint powders use a proprietary formulation, but the white powder is a mixture of titanium dioxide, calcium carbonate, and cornstarch, while the black powder is a mixture of lampblack and graphite. The problem with the black powder is that it gets on everything and produces black smudges that are difficult to remove. I’ll fill unlabeled containers with the black powder, seal them, and then wash them to remove any remaining powder before we label them. Even doing that, we may end up with some black smudges on labels.

08:37 – Friday the 13th falls on a Friday this month.

Well, it’s finally happened. Until now, I’ve been making up solutions for science kits in 2-liter Erlenmeyer flasks, 2-liter soft drink bottles, or gallon (3.8 L) jugs. But one of the solutions I need to make up is the Fertilizer concentrate part A for biology kits, which is supplied in 125 mL bottles. A gallon of Fertilizer A is sufficient for only 30 kits, and I need to make up sufficient for 90 kits. Rather than make up 3 gallons (~12 L) of that solution in separate 1-gallon batches, I decided to make up a single 3-gallon batch. That means I need a largish mixing vessel. Fortunately, I happen to have some 19-liter polypropylene beakers on hand, AKA 5-gallon buckets from Home Depot. They’re bright orange, granted, but they’re clean, sturdy, and chemically resistant.

Unfortunately, they’re not graduated, but that’s easy enough to address. My shipping scales have one-gram accuracy and resolution up to 20 kilos, so I’ll simply tare an empty bucket, transfer 11,356 grams (3 gallons) of water to it, and use a permanent marker to draw a line at the 3-gallon level. Actually, I’ll probably just do the line at 12.5 liters and make up sufficient solution for 100 bottles rather than 90.
