07:40 – I just started reading An Unmarked Grave: A Bess Crawford Mystery. It’s set during WWI. Bess is a British nurse serving in France. She could be my grandmother, literally.

My father’s mother was born in 1893. She trained as a nurse, and joined the US Army when we declared war on Germany. At the time, women were allowed to serve in the US Army only as nurses, and all US Army nurses were women. Age 24, she went to France and spent the rest of the war caring for wounded and ill US soldiers. She survived the flu epidemic. That’s all I know. I don’t know if she served at a field hospital or a base hospital in Paris, or both. She never talked about it. Nor did my father, who may himself not have known.

In fact, grandma wasn’t much for telling stories about the past, period. The only one I remember was the one about December 7th, 1941, when she said she was literally almost lynched as a German spy. She’d hung a quilt over the railing to air it out. Unfortunately, the quilt (which we still have) was white with a pattern of large red swastikas. At the time, my grandmother and other quilters still thought of the swastika as an obscure Indian symbol. Even so, grandma had some quick talking to do to calm down her outraged neighbors. Someone had reported it to the police, who came out to interview her. I think I remember my dad saying that she also got a visit from the FBI. She must have satisfied everyone, because she wasn’t arrested. They let her keep the quilt, which she packed away for 20 or 30 years.


13:05 – We just got an order for seven chemistry kits, which is the most we’ve sold to a single buyer. I think the previous record was four. That order takes us down to eight chemistry kits in stock, with another 30 nearly ready to assemble. I had planned to do 30 forensics kits as the next batch, but I think we’d better do 30 more chemistry kits next instead. Given that we don’t expect orders to peak until August/September, it looks as though we’ll sell a lot of kits this year. Now, the only problem will be keeping up with the orders. We’re still shipping the same day for orders we receive before 11:00 a.m. our time, but that’s likely to start slipping soon.

I’m also placing purchase orders for larger numbers than I’d have believed just a few months ago. Yesterday, I ordered a case of 216 9V batteries and 4,000 coin envelopes. Chemicals that I had been ordering 100 g at a time I’m now ordering 500 g or a kilo at a time. By necessity, I’m spreading out, with raw materials, components, subassemblies, and finished inventory stacked all over the place. Fortunately, Barbara has a sense of humor about it. At least so far.


16:14 – Oh, yeah. With regard to the failed two-day EU summit that commences tomorrow, don’t even bother reading the news articles. The two sides’ positions are already set in concrete, and they’re entirely irreconcilable. France, Italy, and Spain demand that Germany pay their bills, but refuse to give Germany any control over how its money is to be spent. Germany, personified by the new Iron Lady, Angela Merkel, says that’ll happen over her dead body. And she means it. There’s really not any reason to hold this summit. If Germany does not give France, Italy, and Spain what they’re demanding, the three of them collapse, Italy and Spain sooner and France a bit later. If Merkel tries to give them what they want, she’ll be overruled at home, if not crucified. She’d certainly lose the election next year. And, even if somehow Germany agreed to pay all the bills, that simply means Germany will be dragged down with the rest. It’s not going to happen. Everyone knows it’s not going to happen. And yet everyone talks about this summit as though there’s actually even the slightest hope of anything being accomplished. Cloud-cuckoo land indeed.

08:29 – We just signed a contract to replace the deck. The contractor is booked for the next couple of months, so work isn’t to start until late August.

We finished watching series five of Heartland last night, which brings us up to date. Series six premiers on September 23rd on CBC, which means it won’t be available on DVD until September of 2013. Barbara is going on a week-long bus tour this autumn. She hates to re-watch things, so I’ll take advantage of her absence to have a Heartland Marathon and re-watch all 85 episodes.

I got email this morning from a customer who just received a chemistry kit yesterday. The 250 mL glass beaker was cracked, so I emailed him back and said a replacement would go out today. I can’t be upset at the USPS. So far, fewer than 1% of the kits we’ve shipped have been damaged in transit, and that’s a pretty good record.

07:49 – The Roku box is happy with its new hard-wired Ethernet connection, and our Netflix streaming is working again. It’ll be interesting to see if the wired Ethernet connection prevents the occasional drops that occurred with the wireless connection. Our WiFi environment is pretty cluttered anyway.

We continue to build kit inventory for the rush that commences in August. My goal is to have at least 60 each of the biology, chemistry, and forensics kits assembled and ready to ship in August, with the components for 60 to 90 more of each kit queued up.


13:16 – Wow. I suppose it shouldn’t surprise me when the MSM gets something completely, utterly wrong, but this one did. I saw the headline first: Prominent atheist blogger converts to Catholicism

I knew it wasn’t me. I’m certainly an atheist blogger, but few people would call me “prominent”. So I wondered, who could it be? Not PZ, surely? Not Richard Dawkins or Jerry Coyne or Hemant Mehta or Greta Christina or ZOMGitsCriss, or any of the dozens of other Gnu Atheist bloggers I know. Who could it possibly be? So I clicked to read the article. I would certainly recognize the names of the top 100 atheist bloggers, and probably nearly all of the top 1,000.

As it turns out, this “prominent” atheist blogger is a woman named Leah Libresco. I had never heard of her until that moment. She has been blogging for only two years. She has, as far as I know, written no books about atheism, nor been a speaker at any atheist/secularist/skeptic convention, nor been an officer or spokesperson for any atheist/secular/skeptic organization. I’d guess her blog probably gets fewer visitors than my current blog, and certainly fewer than my old blog got back in the days when I commonly got 10,000 visitors on a good day. Nothing against Ms. Libresco. I don’t know her and have never read anything she’s written. But to call her “prominent” goes beyond exaggeration.

Obviously, the only significant thing about this is that someone somewhere has given up atheism to become religious. No surprise there. Religious people become atheists and vice versa. No one denies that. The only significant thing about this is that atheists convert to being religious believers much less frequently than the converse, probably by 1000 to 1. But the MSM makes it seem as though there’s some significance in the decision of an obscure atheist blogger to join the RC church.

07:50 – I had one of those days yesterday that was, as Pournelle says, eaten by locusts. At the end of the day, I’d worked hard all day but felt as though I hadn’t accomplished much.

In retrospect, though, I guess I actually did accomplish a fair amount. It was just that it was a bunch of small stuff. I processed orders and shipped a couple of kits, answered in detail several queries about kits, did more research on shipping to Canada, reviewed the Preface for the forensics book, did final assembly of a dozen chemistry kits to add to inventory, made up boxes and started assembly on a new batch of 30 chemistry kits, downloaded and burned the current version of Linux Mint, and a partridge in a pear tree.

Speaking of Linux Mint, I really have to do something about my main office system. It’s quite elderly, although still fast. (It’s an Intel Core2 Quad Q9650.) But it’s running Ubuntu 9.04, which hasn’t been supported for a long time. This system was scheduled for replacement 18 months ago, but I never got around to it. Barbara’s old system failed, and the only system we had available at the time was the six-core Core i7-980X box that we built as the Extreme System for the 3rd edition of Building the Perfect PC. That one that was to be my new system, but she’s using it now. Meanwhile, my den system has also failed. That was the mini-ITX system we built for the book, and I need to do something about it as well.

So I think I’ll order a replacement Intel Atom motherboard/processor for the den system, rebuild it, and convert it to Barbara’s system. (She mainly does web browsing and email on that system, so the six-core system she’s using now is gross overkill.) I’ll then do a quick refurb on Barbara’s current system and convert it to my new main office system and retire the current one to stand-by status. To replace the den system, I’ll just build a microtower system with a low-power processor.


11:04 – I just ordered an Intel D2700MUD Atom motherboard/processor combo and a 2GBx2 Crucial memory kit for it. I wasn’t about to order anything ever again from NewEgg, so I searched Amazon.com. Amazon didn’t stock that board, but several of their vendors did. I decided to order from PC Rush, which had a large number of excellent reviews. Their price, including free shipping, was $85.55.

I added the item to my cart and then searched the PC Rush storefront for compatible memory. Compared to NewEgg’s search system, Amazon’s sucks. I wasn’t able to find any compatible memory on the Amazon PC Rush storefront. Or perhaps I could have, if I’d been willing to scroll through 300 pages of items from that storefront. So I Googled PC Rush, went to their site, and added the BOXD2700MUD to my cart. Then I went over to the Crucial website and used their configurator to search for compatible memory for that board. It returned only one hit, on the CT2KIT25664BC1067 2GBx2 kit, for $29.99 with free shipping. So I went back to the PC Rush site, which also had that kit, but for $36. I added it to my cart anyway, figuring it was worth the $6 difference to have to place only one order. But when I added that memory kit to my cart (which already contained the motherboard with free shipping), my shipping cost went to $16 for ground shipping. Geez. So I deleted the memory kit from my cart and submitted the order for the motherboard only. It took me about two minutes to order the memory kit on the Crucial site, and saved me $22.

My first thought was to install this motherboard and memory in my mini-ITX den system, but I think instead I may install it in a new Antec Sonata or other micro-tower case–I have plenty of those sitting around–and put it in Barbara’s office to replace that six-core system. The Atom is much, much slower than the Core i7 she has now, but she probably won’t even notice the difference using the system for web browsing and email. I, on the other hand, need as much CPU as possible for doing stuff like video production. I’ll just pull her hard drive from the big system and put it in the new one. Then, with a quick upgrade to the current Linux Mint, she’ll be good to go. I’ll do a quick clean/re-furb on the six-core system, put in a 3 TB drive (which has been sitting on my desk for months now), and rebuild my main system. My current system will go under the desk, not plugged into anything, and sit there moldering in case I need an emergency replacement. Then I’ll probably order another D2700MUD and memory for it and use those to upgrade my den system.


14:07 – With the exception of Angela Merkel, eurozone “leaders” are delusional. Here’s yet another example. At today’s summit of the Big Four (Germany, France, Italy, and Spain) leaders, those leaders spent their time discussing a “growth pact”. The summit was followed by a press conference. A typical headline is something like “Europe’s Big Four Agree €130 billion stimulus package, 1% of EU GNP”. All hail the €130 billion growth package. The problem is, it’s not a €130 billion package; it’s a €10 billion package. That is, only €10 billion is “new money”. The rest is imaginary–leveraging that €10 billion to €60 billion using accounting smoke and mirrors and demonstrably false assumptions–or money that’s already been spoken for and allocated. The eurozone leaders, including unfortunately Merkel, seem convinced that the markets are stupid. The markets will shrug this off, just as they shrugged off the so-called €100 billion Spanish bailout, which hasn’t even been requested yet, let alone approved, let alone paid.

Meanwhile, we keep seeing articles about Merkel coming under pressure. Merkel is not under any pressure. There’s nothing the EU, the IMF, the US, or anyone else can do to force her to pay the outstanding debts of the rest of the eurozone. Her voters across the political spectrum don’t want her to do it. She doesn’t want to do it. She’s not going to do it. Even if she were inclined to do it, the German constitution prohibits her from doing it. And even if she ignored her own convictions and the German constitution, German citizens would crucify her if she did it, perhaps literally. It’s just not going to happen. And yet it’s the only hope for the eurozone, which is why everyone keeps talking about it as though there’s even the tiniest probability of it occurring.

10:01 – Monday, I got an order for a chemistry kit and a biology kit from a woman in Calgary, Alberta, Canada. That’s by no means the first order I’ve gotten from Canada–not to mention a hundred or more serious queries–and I did what I always do: sent email expressing regrets that we can’t ship to Canada and refunded the money.

But I’m getting really tired of disappointing Canadian homeschoolers, so I’ve been trying since then to figure out how to get kits shipped to Canada. Here’s the message I sent to her this morning.

Hi, Marika

Well, I’ve spent about 12 hours looking into shipping to Canada, and here’s what I’ve determined.

1. Both FedEx and UPS say that they’ll ship our kits to Canadian addresses. That’s the good news. The bad news is that it would be extremely costly to do so. Just as one example, FedEx will pay the Canadian authorities any sales tax due, but will then charge you that amount of tax plus an $88 brokerage fee. That’s not including the actual shipping charges, which aren’t cheap. Geez.

The worse news is that neither I nor you would actually know how much it costs ahead of time. For example, if FedEx attempts to deliver and you’re not home to sign for the package, they’ll make redelivery attempts, charging you (IIRC) $16 for each attempt. Unbelievable, but essentially UPS and FedEx expect us to write them what amounts to a blank check, with them telling us after the package is delivered how much it ended up costing. That’s obviously unacceptable for either of us.

2. Right now, we ship kits to US addresses using USPS Priority Mail flat-rate and regional-rate boxes. The USPS will also deliver the Priority Mail large flat-rate box (which is big enough to contain one kit) to any Canadian address. That would end up costing you $40 additional, i.e. $200 total for the CK01A chemistry kit and $210 for the BK01 biology kit.

The issue is that the kits contain hazardous materials. We ship to US addresses under the 49 CFR 173.4 small quantity exemption, which redefines small amounts (less than 30 mL or 30 g) of hazardous materials as non-hazardous if they are packed according to very specific requirements. But 173.4 is a US-only exemption.

I talked in great detail with a USPS support representative. She told me that there shouldn’t be any problem shipping the kits to Canada, but obviously she can’t speak for Canada Post. The USPS has a page for Canada that lists prohibitions and restrictions

http://pe.usps.com/text/imm/ce_003.htm#ep6216933

and it appears to me (and to the USPS support rep) that our kits qualify for shipping to Canada. I tried calling Canada Post and ended up bouncing around their system for a while. The most I was able to get was “it should be okay”.

So, I guess the upshot is that we can ship you these kits with no problem as far as the USPS is concerned. However, what happens at the border with the Canadian postal/customs/sales tax authorities is completely outside our control. I asked the USPS support rep how this would work, and she said that I can just ship the box normally with a postage label with your address on it. Six to 10 days later, Canada post should deliver it and present you with a bill for any customs duties or sales tax due.

This whole thing makes me nervous and I certainly understand if it makes you nervous too. If you want to give it a shot, I suggest ordering just one kit to start with. We’ll run a postage label and customs form, stick them on the box, and ship it. If you want to proceed this way, let me know and I’ll figure out how to arrange payment.

11:35 – UPS showed up yesterday with about 30 kilograms of chemicals. (Of that, about 8 kilos was four liters of concentrated sulfuric acid.) I now have most of the chemicals I need to make up many more biology, chemistry, and forensics kits.

Speaking of forensics, our production editor just sent us the QC1 PDF of the first half of the book. I’ll be working on that heads-down until I get through it.

And speaking of kits, I got an order yesterday for a biology kit and a chemistry kit from a woman in Calgary, Alberta. I emailed her to say that we can’t ship kits to Canada, and that I’d refunded her money. I also mentioned that Barbara and I were watching Heartland and would love to visit the Calgary area one day. She replied that Barbara and I were welcome to stay with them, and could we bring along the kits. I replied that it’d probably be a few years before we’d have time to make that trip, but I’m pretty sure she was serious about her offer of a place to stay. She was obviously disappointed that we couldn’t get the kits to her.

That got me to thinking. I really hate not being able to ship kits to Canada. I really hate disappointing people, and I’ve lost count of the number of Canadian homeschoolers I’ve had to say no to. It seems so stupid. We can ship Priority Mail (air service) to all 50 states under the 49 CFR 173.4 small-quantity exemption, but that’s unique to the US. If these kits are safe enough to transport that the USPS is willing to put them on planes, it seems to me that we should be able to put them on a truck going over the border into Canada.

So I decided to see what could be done. I’ve spent several hours reading Canadian shipping regulations and talking on the phone to FedEx hazmat experts, and I’m going to do the same with UPS. At this point, it seems there may be a glimmer of hope. Although the USPS says that the ORM-D (Other Regulated Materials – Domestic) exemption is unique to the US, FedEx tells me that they’ll accept ORM-D (Surface only) packages for delivery to Canada. The Section 173.4 small-quantity exemption is a subset of ORM-D. For example, under SQE I can ship up to 30 mL of concentrated hydrochloric acid, while for ORM-D I can ship up to (IIRC) one liter. That being the case, the fact that our kits qualify for the Section 173.4 SQE should mean they automatically qualify under ORM-D. But there are a zillion details to deal with, including the fact that SQE and ORM-D have different packaging requirements. And I’m not sure if packaging that is ORM-D compliant for shipments within the US is also acceptable for shipments into Canada. All told, I suspect I’m looking at several days’ work just to determine authoritatively if this is even do-able. And, even if it is, it’d be ground-only, which means a shipment to Alberta or BC might take a week or 10 days to arrive, versus the typical two or three days via USPS Priority Mail. And, no doubt, it’ll cost more to ship the kits, probably a lot more. There may be surcharges for the hazardous materials. And, of course, there’ll be customs declarations and so on to deal with. But at this point I’m hopeful.


15:11 – The EU has announced its latest imaginary “big bazooka”, €750 billion to buy Spanish and Italian bonds on the secondary market, in an attempt to drive yields down. The problem is, that’s the combined nominal assets of the EFSF and ESM, and those assets are mostly imaginary. So now we have the ridiculous situation of Italy, which is bankrupt, guaranteeing the funds needed to buy Spanish bonds, and Spain, which is bankrupt, guaranteeing the funds needed to buy Italian bonds. Or, I suppose we could look at it as Italy co-signing on loans to Italy and Spain co-signing on loans to Spain. Give me a break. This isn’t going to fool investors. There’s no actual money there. Until Germany agrees to pay not just everyone else’s outstanding bills, but future bills as well, this is going nowhere. Which means it’s going nowhere, because there’s no way Germany is going to agree to sacrifice its own wealth to save the spendthrift rest of the eurozone. This shell game has gone on far too long already. Everyone, including the eurocrats, is perfectly aware that it’s a shell game. They just hope investors don’t notice. That’s the cloud-cuckoo land these people are living in.

08:02 – As of this morning, we have only 22 biology kits and 19 chemistry kits in stock, albeit with another 30 of each in progress. Not all that long ago, that would have been a comfortable cushion. No longer.

Homeschoolers are now buying materials for the summer session, and it seems to be ramping up. The scary part is that the real ramp-up hasn’t started yet, and won’t until August, when homeschoolers start ordering materials for the autumn semester. So, at this point, we’ll concentrate first on getting the new batch of 30 biology kits and 30 chemistry kits ready to ship. We’ll then build inventory by doing batches of 30 kits at a time, alternating between chemistry and biology kits. Starting mid- to late-July, we’ll add forensics kits to the mix until we have at least 60 of those in inventory by the time the forensics book hits the stores.


10:46 – Barbara’s going to dinner with her parents tonight and then taking her mom to a 7:00 pm appointment to get an MRI. Apparently, they run that machine literally around the clock. That leaves my dinner up to me.

As my long-time readers know, I’m mildly vegetarian. To be precise, I’m an ovo-lacto-fisho-chickeno-beefo-porko-lambo-almost-anything-that-stands-still-or-moveso vegetarian. Oh, yeah, and definitely bacono. But I do eat vegetables, so to my way of thinking that makes me vegetarian. I hasten to add that I am in no sense of the word a humanitarian.

09:39 – As we build inventory of the biology, chemistry, and forensic science kits for the coming new school year, I’m thinking about which science to do next. Physics may seem the obvious choice, but the truth is that while most high-school students take biology and chemistry, relatively few nowadays take physics. And many of those who do take a physics course do a lecture-based course rather than a lab-based course.

We could do AP biology and/or AP chemistry, but again the potential market for those is much more limited than the market for the mainstream first-year courses. The same is true for more specialized courses like marine biology, anatomy, and environmental science. We’ll do all of those eventually, I’m sure, but for now we want to concentrate on the more mainstream courses. That means working down to the early high-school/late middle-school level. There are two science courses commonly taken in grades 8, 9, or 10 that we don’t have covered: earth science and physical science.


13:52 – My cell phone didn’t last as long as the effects of the Spanish bailout. I ordered the phone back on 21 March. When it arrived a couple days later, I put it on the charger, but never got around to activating it. So late this morning I stuck it on the charger again. It took all of 10 or 15 minutes to show fully charged. Then I went over to the PlatinumTel website to activate it.

As I was doing that, Barbara called to say that her dad was in the emergency room again. She’d taken him to a doctor’s appointment, intending to get him back home and get to work before lunch. But her dad fell, and so she took him to the emergency room. I think his doctor’s appointment was at the hospital, so they didn’t have far to go. Barbara’s cell phone had died, although she’d just charged it. When we hung up, Barbara was leaving to go get her mother and said she’d see if her phone would work plugged into the car charger.

A while later, I heard the key in the front door and was surprised to see Barbara, who was making a flying visit home to grab something for lunch and then head back to the hospital. Of course, I gave her my cell phone. It was all mine for almost 27 minutes. Now it’s hers.

Her dad seems to be okay. He fell to his knees, and doesn’t seem to have done any major damage. Barbara was terrified because he started yelling when he fell and she thought he was seriously injured. So she’s headed back to the hospital to sit with her mom. If they release her dad before 5:00, she’ll take them home. Otherwise, her sister will come over and pick up their parents at the hospital so that Barbara can meet two of her friends for dinner, which was previously arranged.

09:09 – As expected, the markets have responded favorably to the Spanish bailout. That won’t last long. Like all of the bailouts and other actions taken to “save” the euro, this amounts to slapping a fresh coat of paint on a rotting structure. The markets will soon recognize that, as they always do, and Spanish sovereign debt will start heading for the 7%+ range again.

We got fair amount done over the weekend on a new batch of chemistry kits. The only major job that remains is filling a whole bunch of bottles.


09:28 – Wow! That was faster than even I expected. Benchmark Spanish bond yields started this morning just under 6%, and they’re already at 6.2% and climbing. Apparently, investors have already realized that promising a bailout doesn’t mean the money is actually available to do it.


09:31 – And, as of a few minutes ago, they’re at 6.4% and climbing.

08:16 –With the Roku box not working and therefore no Netflix streaming, Barbara and I watched the last disc of Heartland series three last night. Colin watched as well. When Heartland’s Amy is training horses, she frequently tells tells one he’s a “good boy” in the same sing-song voice that Barbara uses to tell Colin that he’s a good boy. Colin loves to be told that he’s a good boy, and he likes hearing it from Amy as much as he does hearing it from Barbara.

We’re getting short on chemistry kits again. We sold four yesterday. We’ll work on making up another batch of 30 this weekend.

Fitch downgraded Spain’s sovereign debt by three levels yesterday, to one level above junk bond status. Although a three-level cut seems dramatic, it actually wasn’t nearly enough. The reality is that Spain is bankrupt, and its credit rating should reflect that fact. Spain is widely expected to request a bailout over the coming weekend, although as usual the amount of the requested bailout will be nothing more than a band-aid. The reality is that Spain needs to be given (not loaned) at least $500 billion over the next year to 18 months. That amount simply isn’t available, nor is there any prospect of it becoming so. Expect further cuts in Spain’s sovereign credit rating after this weekend, and expect the pressure to move next to Italy.
