09:22 – We’re under a blizzard warning for tonight. Well, a blizzard by our standards. Temperatures in the 20’s (~ -5C), with winds of 25 MPH (40 KPH), and two to four inches (5 to 10 cm) of snow.

We got a lot done yesterday on the biology kits. We now have 60 sets of the solids–thirteen of them–packaged, labeled, and bagged into subassemblies. We also started making up 100 sets of tube subassemblies. Those are six glass test tubes individually packaged inside 50 mL polypropylene centrifuge tubes (for shipping protection), with six 15 mL polypropylene centrifuge tubes, all inside a quart ziplock bag. I’ve made up all six of the stains included in the kit–Eosin Y, Gram’s Iodine, Hucker’s Crystal Violet, Methylene Blue, Safranin O, and Sudan III–and today we’ll bottle and label 60 sets of those.


11:47 – I’ve often complained that one can’t buy real chemistry sets nowadays. The kinds of chemistry sets I grew up with have been extinct for close to 40 years. Until now.

John Farrell Kuhns of H.M.S. Beagle is now offering a real chemistry set, the kind I drooled over back in the 1960’s. The hand-built H.M.S. Beagle Master Chemistry Set echoes a bygone era, when millions of boys hoped to find something just like this under the Christmas tree.

10:17 – Along with doing laundry, it’s another lab day for me today, while Barbara labels and fills containers and makes up subassemblies for the biology kits. She’s working upstairs today, filling containers with non-hazardous materials. Tomorrow, we’ll work downstairs, filling containers with hazardous materials. Well, actually, they’re not hazardous, except to our work surfaces and floors. I’m making up several stains today, most of which would indelibly stain counters, tables, and hardwood floors. We’ll fill those containers in the basement.


12:55 – I was doing fine until I made up the last of the stains for the biology kit, Hucker’s crystal violet. When I inverted the container to mix the solution, the cap leaked. So my hands now have pretty (and indelible) purple stains. I wasn’t wearing gloves because this stain is hazardous only in the sense that it, well, stains things. Oh, well. All working chemists get used to having stains on their hands.

10:13 – Today is a miscellaneous day. I’m going to take a break from writing and get some work done in the lab. I also have a few more purchase orders to get out for the biology kits.

Interestingly, I had to fight off a guy today who wanted to order a biology kit right now. As I pointed out, he had no idea what was in the kit or how much it would cost. He wanted to send me extra money and have me refund the difference when we’d finally set the price. I finally convinced him that we would allocate the very first kit to him and ship it as soon as it became available.

07:55 – A comment yesterday got me to thinking. Dave mentioned that if the kits were still available in a dozen years or so, his daughter would be the right age for them.

I replied that we’re in this for the long haul, which is true, but it got me to thinking (again) about what happens if I get run over by a beer truck. As things stand, although Barbara helps with packing, labeling, and other tasks, this is really a one-man operation. I wear all of the hats, from lead scientist to manual writer to IT to purchasing, A/R, and A/P to …. well, you get the idea. The last thing I want to do is grow too fast, which means for at least the next couple of years we’ll be doing things pretty much as we’re doing them now.

But I do want to make sure that if I do get run over by that beer truck, Barbara will be in a position to carry on, either herself or with hired help. I intend to build this business gradually, with the goal being to establish it as a rock-solid enterprise. If for some reason I’m no longer around, I don’t want the business to die. I’ve already made some efforts in that direction. Several months ago, I talked to Mary Chervenak. As Mary is aware, Barbara is not a scientist, so one of the big things she’d need would be a scientific advisor. Mary (and Paul) are ideal for that. They could steer Barbara in the right direction and help her understand sciency things that she wouldn’t otherwise be able to deal with on her own. I’ve also made a start on documenting everything about the business, from usernames and passwords for the website to a procedures manual for making up chemicals to lists of wholesalers, contacts, and account information to business and corporate information.

To be honest, I’m not sure what Barbara would do in that situation. She might just choose to let things drop. But if she does want to continue the business, I want to do everything possible to make it as easy as possible for her to do that. At least until one of my clones is old enough to take over.

07:58 – UPS showed up yesterday with seven or eight large boxes, so we now have about two thirds of the components needed to build the first batch of biology kits. I have a few more small purchase orders to get out this week for the biology kits, but otherwise I’ll be working heads-down on the forensics book re-write.


I signed up for Amazon Prime yesterday, and last night Barbara and I watched our first Amazon streaming video. It was the first episode of Inspector Lewis Series 4, which Netflix doesn’t have on DVD, let alone streaming.

Pretty clearly, Amazon is doing everything they can to make it difficult for people to watch free streaming videos on their service. Instead, they really, really want you to pay for the video. Incredibly, there is no queue for free streaming titles (although there is a queue for purchased or rented videos). To watch a free video, you have to search for the title each time. For example, after we watched episode one of Lewis with our Roku, we switched back over to Netflix to watch an episode of Scrubs. To watch the second episode of Lewis, I’ll have to search for it again, using the arrow keys and virtual keyboard on the Roku.

Amazon’s attempt to force people to pay for videos that they can watch for free leads to a ridiculous situation. When I clicked on the first episode of Lewis, Amazon gave me a choice. As a Prime member, I could (a) watch the video for free, or (b) pay $2.99 to watch it. Guess which one I chose. At least the default option was to watch it for free. I wonder how many people choose the second option.

I read about people who are dropping Netflix streaming and substituting Amazon Prime streaming, which strikes me as ridiculous. Not only is Amazon’s catalog a tiny fraction of Netflix’s, but Amazon intentionally makes it as hard as possible to find and watch free videos. We’ll be treating Amazon Prime streaming as a supplement to Netflix, but nothing more. If we want to watch something specific and Netflix doesn’t have it, we’ll try Amazon. But that’s about it. And I’m sure that that’s exactly what Amazon hopes we’ll do.

09:29 – Darwin Day, and Colin turns a year old today. Some would say he’s now officially a dog, but he’s still very much a 12-month puppy. He is showing some signs of calming down a bit, but he’s still doing stuff like eating bedspreads. In fact, he’s gone through two in the last month. One was shredded completely beyond salvage, but the other is now in my Trooper as a tarp for times when we haul straw, mulch, and other messy stuff in the back.

Barbara and I got quite a bit done yesterday on the biology kits. We’re shooting to have the first 60 kits ready by 22 March, one month before the book is published. That leaves us a bit of slack in case something unforeseen crops up. I haven’t costed out the kits yet, but just eyeballing it I think we’ll be able to keep the price in the same general range as the chemistry kits or perhaps a bit higher.

10:23 – I took the day off yesterday, the first in several months. I’ve come down with a cold, from what source I don’t know since I seldom leave the house.

On the plus side, everything we need to build the first batch of biology kits is either already here or on the way, with just three exceptions. I need to order some potassium dihydrogen phosphate (used in the nitrogen-free fertilizer concentrate supplied with the kit) and some sodium dodecylsulfate (used in extracting DNA). I also have 120 50mm funnels on backorder until 21 March.

Today, I’ll get those last purchase orders issued and then jump back into the rewrite of the forensics book.


11:44 – I decided to take it easy today as well. It’s hard to do what I do when annoying virus symptoms are distracting me.

I see the Greeks are rioting. I made a comment the other day about them needing to cut 1.5 million government jobs, and someone pointed out in the comments that there were “only” 800,000 government employees in Greece to start with. Actually, no one, including the Greek government, knows how many government employees there are. The commonly quoted numbers between 800,000 and 1,000,000 are almost certainly far lower than reality. The best numbers I had as of last autumn were between 1.2 million and 1.6 million, depending on how one counts them. At any rate, my suggestion was actually to get rid of all of them and start over.

Barbara and I started watching Lillyhammer, Netflix’s first co-production of original programming. It stars Steve van Zandt (familiar as Silvio Dante from the Sopranos and as a member of the E-Street Band) as a New York mafia guy who is relocated by witness protection to Lillehammer, Norway. As we watched the first episode, one of the story arcs made me think about why Europe is moribund. The gangster decides to star a bar/nightclub in Norway, and finds that he has to go through incredible hoops to do so. That’s commonplace in Europe, whereas in the US someone who wants to start a business just starts a business. Here, it’s literally pro forma–fill in a couple of forms and you’re good to go. Is it any wonder that the US is dynamic and Europe moribund? If Obama really wants to get things going, all he has to do is exempt small businesses–say, those with fewer than 100 employees, or better 1,000 employees–from all city, state, and federal regulations and taxes. Make small businesses a protected species. Unemployment would plummet, tax collections would skyrocket, and government outlays for social programs would fall off a cliff.

08:22 – I’ve issued purchase orders for the bulk of the components for the first batch of biology kits and another batch of chemistry kits. I still need to issue a bunch of small POs to vendors that supply only one or two of the kit items each.

Once again, the effects of inflation were very noticeable. Since my last batch of orders in November, prices have increased by an average of maybe 6%. Many prices were unchanged and there were even a few reductions, but some prices increased by 15% or more, and the price on one item literally doubled. The main reason for the increases is that vendors issued their 2012 price lists in January, which they’ll generally honor through June or December, depending on the vendor.

09:27 – The biology book is complete and off to the MAKE production crew. We’re finished with it, other than a QC pass or two, where we’ll do a quick check of the PDFs before the book actually goes to the printer. Amazon says the book will be available on 22 April, and I suspect that’s pretty accurate.

I’m off now to finish putting together purchase orders for the biology kits and more chemistry kits. Once I get those issued, it’ll be back to work on the forensics book re-write.


I see that there are Greek riots scheduled for today. Merkel cut Greece loose months ago, and it’s finally coming home to roost. As I predicted months ago, that 30% “haircut” for Greek bondholders turned into 50% and now appears likely to reach 80%, nominally. In fact, as I said, it’s actually going to be a 100% writedown, as Greece rapidly heads toward complete bankruptcy, with Portugal not far behind and Spain and Italy in the on-deck circle. The dominoes are starting to topple.

The fallout from the collapse of the euro isn’t likely to affect the US as deeply as some people seem to fear. US banks have very limited exposure to European debt, and exports to Europe are a fairly minor part of overall US production. Although clearly the exposure varies from state to state, on average US states probably do less than 2% of their business with Europe. Even if that disappears entirely, which it obviously won’t, the impact on US businesses will be relatively minor. The same can’t be said for China, however. China, which is leveraged out the wazoo, exports a large percentage of its overall production to Europe, and that export business is declining fast. That loss is already approaching levels that are catastrophic for China, and it looks like it can only get worse. Expect to see Chinese goods get cheaper as China tries desperately to keep exports up by increasing volumes to the US.

09:51 – I saw the headline in this morning’s paper, and told Barbara that San Francisco had beaten Boston. She looked at the article later, and said that it was New York that had beaten New England (or vice versa; I don’t put useless information like that into anything but nano-term memory). I figured the Giants had moved from San Francisco to New York and the Patriots from Boston to New England (somewhere else in New England, I guess), but Barbara said she was pretty sure the Giants had been in New York for a long, long time. I told her I was almost sure I remembered them being in San Francisco. So we checked Wikipedia and found that we were both right. There was and still is a team in San Francisco named the Giants. Barbara explained to me that they play with a different-shaped ball. It still seems to me to be a strange thing for adults to concern themselves with.


Brian Jepson sent me a new batch of lab chapters with his comments, so that’s first on the to-do list this morning. Next up is generating purchase orders for components for the biology kits and for more chemistry kits. Once I finish those, it’s back to re-writing the forensics book.
