08:21 – Barbara took today off work to get some stuff done around the house and yard. This afternoon, she’ll start labeling a thousand or so containers for the new batch of biology kits. I’ll be making up solutions to fill the bottles.

Yesterday, I commented, “Unfortunately, I had no idea if we had any DEET and, if so, where it was. The first thought that crossed my mind, of course, was “I wonder how difficult this stuff is to synthesize.”” A lot of people thought I was kidding, but I was serious. It’s a generational thing.

Our friend Paul Jones is a professor of organic chemistry at Wake Forest University, and is half a generation younger than we are. I suspect that most or all of the time Paul needs a chemical for one of his classes, he just orders it from Sigma or Fisher or Alfa. It didn’t used to be that way. When I started undergraduate chemistry in 1971, the chemistry department ordered a lot of the chemicals they needed, but they also made a lot of them, often liters or kilograms at a time. In fact, it wasn’t unusual for rising junior and senior chemistry majors to have summer jobs at the college. They’d spend the summer doing syntheses. For many of the chemicals, it a lot cheaper to make them rather than buying them, even assuming that they were commercially available. That wasn’t always the case.

I remember talking to one of my chemistry professors, who would have been in his late 50’s at the time. He started off on the “you kids don’t appreciate how easy you have it nowadays” thing. When he was in undergrad chemistry in the 1930’s, he worked summers at the college synthesizing the chemicals they’d need for the following year. He said that about the only thing they bought was common precursors like acids and simple organics. Everything else, they made.

So, yeah, I was serious. My first thought really was, “I wonder how difficult this stuff is to synthesize.”


Speaking of which, I spent some time on the phone yesterday with John Farrell Kuhns, the owner of H.M.S. Beagle, a full-range home science supplies vendor in Kansas City. Among many other goodies, John carries a huge selection of raw chemicals, something like 700+ chemicals at last count. I was telling him that Barbara and I were about to start making up chemicals for a new batch of biology kits, and he commented that sometimes it seemed that he did nothing else all day long except label and fill chemical bottles. Tell me about it.


15:28 – Barbara is labeling bottles while she watches Felicity on Netflix streaming. She started by labeling 15 sets each for the substitute chemicals we ship with the Canadian versions of the chemistry and biology kits, and then got started on 30 sets each of the 15 mL bottles for the US biology kits. She works with a sheet of labels in front of her, a large box of unlabeled bottles on one side of her, and a labeled plastic bag to receive the labeled bottles on the other side of her. She said a few minutes ago that she was running short of the 15 mL bottles, so I went back to the stock room to refill her supply box. When I told her that I’d had to open the next-to-last case of 1,100 of those bottles, she commented that it was time to re-order. Which it will be soon. Those 2,200 bottles are roughly 80 to 100 kits worth, depending on the kit. And as I was refilling her box of unlabeled bottles, it occurred to me that I’d never imagined that I’d ever think that having only 2,200 new 15 mL bottles would constitute a shortage, or that I’d ever be transferring such bottles with a large scoop.


16:03 – So, Barbara is sitting in the den labeling bottles and watching Felicity. For those of you fortunate enough never to have seen this TV series, it’s about a bunch of whiny, obnoxious college students. The women are women, and the men are women too. So, I can hear the audio from my office. The students are sitting in a chemistry lecture, and the professor says, and I quote, “There are three main aspects to stereochemistry: chirality, handedness, and symmetry.” Say what? I shouted in to Barbara that chirality and handedness are synonyms. She thanked me. Thinking perhaps I could help her decipher the plot, such as it is, I then shouted in, “That guy’s not really a chemistry professor; he’s just pretending to be one.” “He’s an actor,” she replied. As though that’s an excuse for reciting garbage lines.

And, speaking of men being men, I saw an article about Zuckerberg the other day that mentioned that he wears the same thing every day, a gray t-shirt, of which he owns about 20 identical ones. He also mentioned that he has one drawer, “like men everywhere.” Ain’t that the truth? I mentioned the article to Barbara, who said she’d already read it and, of course, thought of me.

08:47 – The prepared microscope slides I ordered for the LK01 Life Science Kit arrived Monday. As I was unboxing and checking off items on the packing list, I was struck by a cunning plan. Although these slides are intended for the Life Science kit, there’s no reason they couldn’t be used as a core slide set by people using the BK01 Biology Kit. So I sent the following email to people who’d purchased the biology kit:

We spent several hundred dollars buying the prepared microscope slides that we used to shoot the images in Illustrated Guide to Home Biology Experiments, so we know how expensive it can be to obtain the prepared slides you need for a biology course. That’s why we included a disc of high-resolution copies of the images from the book with the BK01 Biology Kit. And, although those images are useful, they’re not a complete substitute for using actual slides.

We’ve had many emails from people who’ve bought the BK01 Biology Kit, asking us if there is a source for a core set of prepared slides that would at least hit the high points. After a great deal of looking around, we concluded that the slide sets available were either too expensive, had a poor selection of subjects, or were of very poor quality. So we decided to put together our own set of core prepared slides, with the goal of picking a dozen or so key slides that we could offer at a reasonable price. We finally settled on the following 15 slides:

□ Amoeba (wm)
□ Anthers, lily (cs)
□ Bone, compact (cs)
□ Egg, horse ascaris (sec)
□ Euglena (wm)
□ Frog Liver (sec)
□ Hydra, budding (wm)
□ Leaf, lilac (cs)
□ Lichen (sec)
□ Mitosis, Onion Root Tip (ls)
□ Muscle, involuntary smooth (cs/ls)
□ Muscle, skeletal (cs/ls)
□ Neurons, multi-polar motor (wm)
□ Paramecium (wm)
□ Stems, Monocot and Dicot (cs)

These slides are from the same manufacturer who produced the slides we used for the images in Illustrated Guide to Home Biology Experiments.They are of decent quality, although they’re by no means the best available. (We’d love to offer those top-quality slides, but they’d cost anything from $8 to $20 each, so we’d have to price a set of 15 slides at $150 or so rather than the $52 we sell this set for.)

One of the reasons we hesitated to offer a prepared slide set is that our wholesalers typically stock few or no prepared slides. They’re special-order items, and it can take anything from several weeks to six months from the time we order the slides until they actually arrive.

We ordered 30 sets of these individual slides some time ago, and they arrived yesterday. We’ll be assembling the sets over the next few days, and will be ready to ship sets by the first of next week. We wanted to give those of you who’ve already ordered the BK01 Biology Kit the first opportunity to order a slide set or sets.

If you’d like to order a set, visit the BK01 Biology Kit home page:

If the demand exceeds the supply of 30 sets we currently have available, we’ll ship the first 30 orders we receive. If you order a set and are not among the first 30 buyers, at your option we’ll either refund your payment or put your order on our backorder list, to be shipped as soon as we’re able to build more sets.

The set price includes USPS Priority Mail shipping. Unfortunately, we can ship these sets only to US addresses, at least for the time being. No Canadian orders.

So now Barbara and I need to make up a batch of 30 of the prepared slides sets. We’re already taking orders for them, and I’m telling people that the sets will ship Monday. Meanwhile, our inventory of biology kits is getting low enough that it’s becoming critical. Since we started shipping kits more than a year ago, we’ve had to backorder kits only once, and that for only a couple days. If we don’t get on the ball, we’re likely to have to backorder biology kits, and I hate doing that.


14:17 – The other day I ordered a mouse, keyboard, and display from the Costco web site. The display hasn’t shipped yet, but UPS showed up a few minutes ago with the mouse and keyboard, in separate boxes. The mouse was fine, but the keyboard box was badly damaged, with most of the corners crushed in, one end ripped, and the sides dented in and creased. It looked as though the UPS truck had run over it, literally. I shot some images of the box and then called Costco. They’re shipping a replacement, and said it wasn’t cost effective for me to return the damaged one. Waylon, the rep, said to go ahead and open it, to pitch the keyboard if it was damaged, and if it was okay just to keep it as a spare.

This is yet another reminder of why I don’t use UPS, and would prefer that my vendors didn’t either. Of all the hundreds of kits we’ve shipped, almost all of them have arrived intact. We’ve had, IIRC, two broken thermometers and one broken beaker. Oh, yeah, and one kit delivered to a Florida address just before a tropical storm hit. That kit got so wet that the cardboard box disintegrated, but everything in it survived unscathed. I tend to think of the plastic bags we use for interior packing as protecting against leaks from the chemical bottles, but they also do a decent job of protecting the contents from tropical storms.

Conversely, nearly all of my wholesalers use UPS, and we get a lot of boxes delivered. I’d guess that at least a third of those boxes have visible damage, although it’s often minor, such as a crushed corner or two or perhaps a big rip in one side. I guess my wholesalers have learned what they’re up against because there’s usually no damage to the contents.

That’s one of the main reasons I’m loyal to USPS, although by no means the only one. USPS is also, in my experience, faster than UPS or FedEx for any shipping option that’s even close to the USPS price. For example, I shipped a chemistry kit last Saturday to Bethlehem, Pennsylvania, near Philadelphia. The USPS says Priority Mail normally takes one to three business days in transit, according to the zone. Bethlehem is definitely not in the local zone, and I expected the transit time to be two days. It arrived Monday, in one business day. Same deal on shipments out to the west coast, which are definitely supposed to be three days in transit. Quite often, USPS gets the package to an address in LA, Seattle, and other large west coast cities in just two business days.

USPS also doesn’t dick around with all the surcharges that UPS and FedEx charge. The first time I considered shipping kits to Canada, I looked into using UPS or FedEx. The problem was, I couldn’t figure out how much it would cost to ship a package. I knew how much the package weighed, its dimensions, the origin address, and the destination address. That should be sufficient to get a firm price. It’s not. UPS and FedEx both have all kinds of added fees for different stuff. If they attempt to deliver and can’t, they charge a redelivery fee. They charge different amounts depending on whether the address is residential or business. I was flabbergasted when I looked at the number of different add-on fees I might or might not need to pay, many of which were entirely outside my control. USPS, on the other hand, makes it extremely simple. I use flat-rate boxes and regional-rate boxes. The flat-rate boxes are just that; they cost the same amount regardless of where they’re going, as long as it’s a US address and as long as they’re under a generous weight limit. (For example, the large flat-rate box ships to any US address for $14.62, and can weigh up to 70 pounds; the regional-rate box B, which is what I usually use, has a weight limit of 20 pounds.) Oh, and the boxes are free. With UPS or FedEx, I’d have to buy boxes, which aren’t cheap.

Several people have asked me why I ship via USPS instead of using UPS or FedEx. That’s why.

10:04 – Oddly, given all of the hundreds of science kits we’ve shipped, today was the first time we got an order for a kit to be shipped to an APO address. Shipping it was just like shipping any other kit, with two exceptions. First, the city was “APO” and the state was “AE”, and second I had to fill out a customs declaration, which seems strange. Oh, yeah, and USPS doesn’t give a delivery estimate for Priority Mail APO shipments. Express Mail would be delivered Friday, so I’m guessing that Priority Mail will get the box to the customer sometime next week.

It appears that Spain is likely to request a second bailout this coming weekend. Germany may be a problem, as many of its politicians are loathe to approve a second bailout so close on the heels of the €100 billion they approved for the Spanish bank bailout a couple months ago. At this point, it’s pretty clear even to committed europhiles that Spain is going down the toilet, with Italy likely to follow soon thereafter. Germany is finally waking up to the fact that its taxpayers are already on the hook for as much as €1 trillion, less whatever minor amounts they can recover after the crash. They must realize that providing additional funding in the hopes of delaying the final crash of the euro is simply throwing good money after bad. Germany, Holland, Finland, and now Austria are all sending strong signals that they’ve had enough.

09:30 – Ubuntu 12.04 is hateful. The Atom system in Barbara’s office is now running Kubuntu 12.04. Very slowly. Extremely slowly. As in, when I click on the icon at the lower left corner to bring up the main menu it may take 15 seconds or more for the menu to appear. I’m not sure what I did to cause this, but I think it’s my fault. I could swear that the performance was snappy before I started playing around with the installation. The only thing I remember doing that should have affected performance was turning off the screen effects, ironically in an attempt to minimize the load on this minimal system. Right after I did that, the system started acting like molasses in January. So I toggled the effects back on. Still slow. I rebooted and verified that the effects were still enabled. Still slow. Meanwhile, Barbara would like to be able to check her mail, post to her blog, and so on. I may end up punting and connecting her original system back up.

One thing’s for sure. The display in the den is wonky. Today I’ll order a new display, along with a new mouse and keyboard.


11:57 – I decided on a tactical withdrawal, AKA an advance to the rear. I’m currently in the process of blowing away the Kubuntu installation on the Atom system now in Barbara’s office and replacing it with Windows 7 Home Premium 64-bit. Mainly, I just want to see how it runs. Once it’s installed, I’ll disconnect everything and reconnect Barbara’s old hex-core system, which is still sitting under her desk. That gets her email and web and everything else she’s used to. Then I’ll set that Atom system aside for the time being.

I have a new display, keyboard, and mouse on order from Costco, which’ll probably show up late this week. Meanwhile, the DVD writer in my office system no longer writes discs. The most accessible replacement drive is in the Atom system that’s currently in the den, so I’ll pull that drive and install it in my office system for now. At that point, Barbara will have what she needs, and I’ll have what I need, for now.

As of this morning, our inventory of ready-to-ship biology kits was at zero. I found an order for one in my email first thing this morning, so I boxed up the six that were almost ready to go and shipped the one that had been ordered, leaving me with five in stock for now. Based on recent order history, those five biology kits may be anything from a one- or two-day supply to maybe a week’s worth. That’s uncomfortably little, so as soon as I get the computer stuff done I’ll get started on making up another batch of 30 biology kits.

I did learn something about PayPal from that biology kit order, which came in late yesterday evening. Every six months or so, we’re forced to increase the price of our kits because our wholesalers increase their prices. To give people a chance to order at the old price, I’d updated the main biology kit page a couple weeks ago to announce that the kit price would increase from $170 to $185 as of 1 October (or $210 to $225 for kits shipped to Canada).

So, yesterday evening I logged on to my PayPal account and updates the relevant buttons. When I did that, PayPal generated new button code, which I copied/pasted into the HTML of the biology kit main page. I intended to publish that page first thing this morning, putting the new prices into effect. But the kit order that came in yesterday evening was charged at the new price, so obviously that button code in the HTML page doesn’t control the price. I emailed the customer, apologized for charging $185 instead of $170, and refunded her the $15 difference.

09:18 – I’ve just been reading the results of the Spanish bank “stress test”, which concludes that under the “adverse scenario” Spanish banks may need a bailout to the tune of up to €60 billion. The problem, as with all of the past “stress tests”, is that the “baseline scenario” is simply ridiculous and the “adverse scenario” is in fact the rosiest possible scenario. Here’s their explanation of their scenarios.

The adverse scenario was deemed by the Steering Committee to be appropriately conservative, both relative to the past 30 years of Spanish macroeconomic indicators (the economic scenario being three standard deviations away from long-term average for the three years of the exercise), as well as relative to adverse scenarios used in recent stress tests in peer jurisdictions (e.g. the EBA Europe-wide stress tests and the US CCAR). Moreover, the adverse scenario included a third year of recessionary conditions, unlike the two-year period commonly seen in other stress tests. (See Appendix: Macroeconomic scenarios for further analysis).

The reality is that perhaps €150 billion is about the best they can possibly hope for, and €250 billion or more is certainly not out of the question. Imagine that for the last 30 seconds a bicyclist has been riding along on more-or-less level ground, with small ups and downs. That’s the source of the historical data for their scenario. But a couple seconds ago, that bicyclist drove off a cliff, and he’s still falling. What they should have done was use historical data for only the past two or three years. Instead, they buried that recent, more significant data, with 28 years’ of long-term averages. Geez.


13:10 – Uh-oh. Barbara’s over at her parents’ old house cleaning things out. I just took Colin for a walk down the corner and back in drizzling rain. On our way home, I spotted what I thought was a kid’s bracelet or necklace in the middle of the street. Upon closer examination, I concluded that it was a dead juvenile Carolina Flatsnake (Snakus flattus carolinensis). I need to remember to mention that to Barbara before we walk Colin again after she gets home. I’d hate for her to be surprised.

I just shipped the last two biology kits we had in stock, along with two chemistry kits. Two customers each ordered one of each kit. We still have a dozen chemistry kits in stock and half a dozen more biology kits and 15 chemistry kits downstairs ready to pack up, which means I really need to get to work on making more of the biology kits.


16:10 – Three cheers for Whitney Kropp, the teenage girl in Michigan who was the victim of what the MSM describes as a “prank”. In fact, it was a vicious attempt to cause her pain, an unpopular student whom a bunch of punks decided as a “joke” to elect to the homecoming court. When she found out that they were making fun of her, she considered killing herself. Some prank. Instead, she decided to show them they were picking on the wrong girl. When the story hit the news, Whitney found overwhelming public support. Local businesses and the public, local and remote, donated funds or services to buy her a prom gown and accessories and treat her to a makeover. She attended the coronation surrounded by cheering fans.

And what I can’t figure out is why these vicious children were making fun of her appearance. No, she’s not drop-dead gorgeous, but she’s certainly a reasonably attractive teenage girl. What is their problem?

Kudos also to her date. I suspect there were a lot of guys lined up to be her escort. And I hope those punk kids realize what miserable excuses for human beings they are.

08:28 – Thanks to the kindness of a reader, I now have a legal copy of Windows 7 Home Premium. I attempted to install it on the new Atom system in the den yesterday afternoon, and the system behaved exactly as it had when I attempted to install several flavors of Linux. What’s worse is that it’s behaving exactly as the old Atom system was behaving. With the old system, I thought at first that the problem was the video drivers in the new releases of Linux. I then concluded that it was a hardware problem. I then replaced the system, which behaved the same way. I then attempted to install Windows 7, which behaved the same way. I now conclude that the problem is either the display, although I’ve never seen a display behave like this, or perhaps the cable, although I’ve used both analog and digital cables. The next step is to connect the old system to the TV and see if it works. If so, I’ll replace the display and cables and end up with two functional Atom systems, one for Barbara’s office and one for the den.

As we approach the end of September, kit sales are definitely getting more sporadic. Some days, we ship three or four kits, other days one or two, and some days none at all. The next couple of months are likely to be slow, averaging one or two kits a day. Things will pick up again in early December, as people start ordering kits for Christmas and the beginning of the second semester. Then around mid-January they’ll drop off again and remain slow through about April, when they’ll start to pick up again. We’ll ship a lot of kits in June and then be covered up with orders again in July and August and into September.

I want to have two more kits available for 2013, which means I need to take advantage of these slower periods to get the kits and associated manuals complete. My goal is to complete the Life Science (grade 7) kit and documentation in October and November and be ready to start shipping kits in early December. That gives me mid-January through April to do the Physical Science (grade 8) kit and documentation and have them ready for summer shipments.

Ideally, I’d like to have a third middle-school kit–Earth and Space Science–also available next year, but I don’t think that’s going to happen. I simply won’t have time to write the documentation and design and produce the kits and still get everything else done.


11:54 – Wow. If the riots in Spain were bad, the ones now going on in Greece are catastrophic. Various reports put the figures at 50,000 to 100,000 Athenians rioting in support of the general strike. I’m actually surprised that the Greek government has been able to field as many riot police as they have. The sympathies of most of those police officers must be with the rioters. And those police are facing desperate people armed with Molotov cocktails. It may not happen this time, but with Greece facing almost daily protests and riots, sooner or later the cops are going to respond with lethal force. Greece is already effectively ungovernable. Once the government starts shooting protesters, there’s no way back. And the Greek people have not yet begun to experience the level of suffering that they’re inevitably going to face. They’re throwing firebombs now. What are they going to do when the money completely runs out? We’re looking at the beginning of what is likely to become a bloody civil war.

08:09 – With autumn arriving in Winston-Salem, there’s a little Jap in the air. Our overnight lows have been in the mid-40’s (~ 7C). We aren’t running the furnace yet, so during the day it’s getting down to the mid-60’s (~ 18C) indoors. We generally don’t switch over the whole-house system from cooling to heating until mid- to late-October, instead using the natural gas logs in the den on chillier evenings.

We ran out of chemistry kits yesterday, when I shipped the last one in stock, along with a couple of biology kits. Fortunately, we had another 30 chemistry kits in progress, with 15 of them requiring only boxing up. We’re in good shape on forensic science kits, but we’re down to a dozen or so biology kits, so building another 30 biology kits will be next on the to-do list. That and building the first batch of life science kits, once I’ve actually finished writing the lab manual for life science.


10:35 – Until a couple of weeks ago, I’d planned to vote for Gary Johnson. Then OFD got me to thinking that maybe I shouldn’t vote at all. Well, I’ve made my final decision. Pat Condell for President.

08:29 – Barbara arrived home yesterday afternoon. She called when she was about half an hour out, so I left the front door open so that Colin could lie there at the door and watch for her. Eventually, I heard frenzied barking, immediately followed by the sound of the door opening and Barbara’s voice. He’d watched her arrive and stand out at the curb talking to Marcy for several minutes without saying a word. It was only when she actually got to the door that he started barking. He does that with the mailman and UPS guy, too. Lying in wait to pounce. He scared the crap out of the FexEx guy the first time he did that.

I started writing lab sessions for the life science kit yesterday. The one I decided to write first, which will actually be in the four or fifth lab chapter, is about observing osmosis and plasmolysis in plant and animal cells in hypotonic, isotonic, and hypertonic saline solutions. I’m using a red onion as a source of plant cells. I’d originally intended to use a smear of ground beef as a source of animal cells, but while I was giving Colin a pill the other day I had what may be a better idea. Barbara buys containers of very thinly-sliced lunch meat at the supermarket. I’m going to try using that.


11:39 – Border Collies have some truly bizarre quirks. Colin loves sticks, which is normal. When we return from a walk, he’ll often grab a stick and indicate that he’s ready to run around in circles like crazy. He often maintains a 2- or 3-minute mile pace for several minutes, until he’s gotten at least a couple miles of running and I finally get dizzy from turning around and around.

The only problem is the sticks. After he finishes running, Colin often comes in coughing and choking from the bark and wood chips he’s swallowed. So a week or so ago, I decided to make him some running sticks. I got an old broom from Barbara and we cut the broomstick into convenient lengths. The first trial didn’t go well. As I was getting the leash connected, Colin completely ignored the running stick. We went out the front door, and he continued to ignore it. I held it up to him and said, “Stick!” He put his ears back. I tossed it out onto the front walk, where it made the ringing sound of dried hardwood. That scared him. He finally approached the running stick, very cautiously, and sniffed it. I threw it a few feet into the yard, he chased it, stood looking down at, and then turned and walked away. Hmm.

After some effort, I finally convinced him that the running stick was not his enemy. He finally picked it up and carried it down the street. As usual, he dropped the stick when he noticed something more interesting. He did pick it up on our way back to the house. So, we’re standing in the front yard with him holding the stick. I said my usual to get him started, “Let’s run around like crazy in circles!” He took off at a slow trot, did half a circle, dropped the running stick, and looked at me, expecting me to pick it up and throw it for him. Apparently, he decided that the running stick is a toy-to-be-thrown rather than a stick-to-be-run-with.

So I tried to convince him otherwise, over many sessions over several days. I keep repeating “Stick!” hoping that he’ll change his mind. At this point, he’ll pick it up and run in circles with it, but only very half-heartedly. I’m lucky if he’ll do two full circles at a slow trot, versus 50 or 100 running dead out with a “real” stick. Geez.


I am at my wit’s end trying to get my new den system to run Linux, any Linux. I’ve tried Ubuntu, Linux Mint, PCLinuxOS, and several other distros. I’ve even tried Fedora. I’ve actually had Linux Mint up and running twice for most of an evening each time. I disabled the screensaver and power saving mode and everything appears to be fine. Then the next morning there’s no video. This is driving me nuts. Normally, I’d figure there was a hardware problem, but I’ve run into this before. This is definitely a problem with Linux video drivers or some other software.

Just to rule out hardware problems, I actually considered installing Windows. The trouble is, the latest version I have is XP, which I don’t think would install on this hardware. Some time ago, someone offered to send me a Windows 7 disc and activation key, saying he had a group of keys and plenty to spare. The trouble is, I can’t remember who made that offer. If he reads this and is still willing to mail me a disc and activation key, please let me know.

08:22 – Barbara is due back this afternoon or early evening. Colin and I can’t wait.

With only about six weeks left until the election, the EU is doing its part to help re-elect Obama. The IMF, the EU, and the ECB (the so-called Troika) were to have announced their decision about more bailout money for Greece next month. Instead, they’re delaying the announcement until after the US elections, which makes it abundantly clear what their decision is going to be. They’re going to cut off Greece, letting it go down the toilet, and they’re afraid that the inevitable economic earthquake would damage Obama’s chances. I hope that their cynical attempt to influence US elections fails miserably and that the euro collapses just in time for the election. I’d rather see the eurozone collapse entirely than see Obama re-elected. Not that O’Bomney would be much better.

I decided to expand the basic set of prepared microscope slides for the Life Science kit from 10 to 25 slides and make the slide set optional. That’ll lower the base price of the Life Science kit and avoid forcing people who already have some or all of the necessary slides to purchase something they already have. I’ll also make that slide set an option with the biology kits. I issued a PO yesterday for the first batch of 25 prepared slides. We’ll get the prepared slides in bulk and have to assemble the sets ourselves.

08:49 – Barbara’s been gone two days now, and Colin is taking it pretty well. At night, he’s taking advantage of her absence by stretching out full length on her side of the bed–with his head on her pillow, yet–instead of having to curl up in a little dog ball at the end of the bed. Still, he’ll be happy when she returns home tomorrow, as will I. I made it through seven episodes of Heartland last night, S4E17 and 18 through S5E5. That leaves 13 episodes of S5 and S6E1 remaining, which I won’t get through before Barbara returns.

I finally took the time to install a DVD writer in the new system sitting in the den. I’d used a borrowed optical drive to install Ubuntu on that system. It appeared to work fine, until power-saving kicked in, at which point I could no longer get any video even after a cold start. So last night I installed a new Samsung optical drive I’d gotten from Amazon.com and installed Linux Mint. Everything went as expected, and I immediately turned off power-saving mode. I used the system all evening, and finally decided to re-enable power saving to kill power to the display after 10 minutes. I watched the clock ticking down. At 10 minutes, sure enough, power saving kicked in and cut power to the display. I moved the mouse, and the screen came up normally. Success. Then, this morning, I moved the mouse again. The video was dead. So when I have a moment, I’ll try restarting the system. If it comes up, I’ll disable power saving entirely. There’s something going on with Linux power saving and this Intel Atom motherboard, but I’m not sure what. Worst case, I’ll just manually power the display on and off as needed.

I’m working on a core set of prepared microscope slides for the Life Science kit. I think we’ll include that core Slide Set A with the kit. It’ll be 10 top-priority slides of specimens that are difficult to prepare at home, things like onion root-tip mitosis, cross-sections of monocot and dicot stems, and so on. Then, as an option, we’ll offer another 10 or 20 slides as Slide Set B, which’ll include second-priority slides.
