Package Camera

A while back I wrote a post talking about the cameras we’ve set up around the house and the software that manages it all (BlueIris.) There’s nothing terribly new in this post except to give a long term test update and say that I’m LOVING this setup. The garage cam lets me easily check to make sure that I remembered to put the garage door home or see if my family is home so I can ask Tyla to defrost some meat for dinner. And since we don’t regularly use our front door, the camera there is a great way to know that we have a package waiting or that someone left a flyer in our door. I even get an email showing a couple images and a 5-second video of whoever was at our door. All of the cameras are great but those are the two that I use the most regularly and I’m eager to add some more coverage.

If you ever want help with a similar setup for your house, let me know. I’m happy to share info. You can get going with one camera and the software for around $100-$125 and then each additional camera after that is about $65. You technically can skip the software but it makes life a lot easier.

What If: Amazon Stock

In yesterday’s post about all my Amazon orders, JonathanC posted an interesting comment: “How about this one as a Power BI challenge: current value of the portfolio if you had purchased stock of Amazon instead of the product.” … Challenge accepted!

I already had a list of all my Amazon orders. I think headed to Yahoo Finance and downloaded a daily history of Amazon stock stretching back to 2001 when I made my first product purchase. That came as a CSV file too. Both files got loaded into Power Query. I did a merge on the date column, removed the columns that I didn’t need, and added a custom column that was the money spent divided by the closing share price that day. That told me how many shares I could have purchased. A quick sum over that column divided by a sum of the money spent revealed that I would have made an 81% return on my money! But wait a minute, transactions aren’t free. If I was pay $8 per transaction then I would have only made a 37% return. But that’s silly since I probably wouldn’t have bought $10 of stock at a time like I do with Amazon orders.

Amazon Order History

Did you know that you can download a report of your Amazon orders? I pulled all that data into Excel and started playing with our Power BI toolset even though it was a pretty simple scenario. Here are some of the facts I discovered:

  • First order: Ingenious Pursuits: Building the Scientific Revolution, January 11, 2001. This would have been my Junior year at Purdue. I discovered that some books were cheaper on Amazon than our bookstore. Strangely they didn’t have many of my textbooks and even then, they weren’t always cheaper. Times have changed!
  • Most popular item category: Health & Beauty
  • In our current home, we order 3.3 times more items per year than we did in our last home.
  • There is an average of 1.7 days between ordering and shipping. The median is 1. There are some outliers when I made orders that weren’t fulfilled by Amazon and they can take forever to ship.
  • Item purchased most often: Purina Pro Plan Dry Adult Dog Food, Large Breed Formula, 34-Pound Bag
  • 804 total items ordered

Here are some graphs over the data. It will be pretty obvious that I signed up for Amazon Prime in June of 2008. On a side note, the recent Amazon Prime price increase doesn’t bother me at all. It’s still one of the best deals in online shopping, not to mention that I also get some free Kindle books, and a pretty good collection of streaming video for free. They could charge a lot more and I’d still pay for it.

March Madness Bracket Update

I haven’t been able to watch much of the tournament, but I’ve seen a few recaps of some very exciting games and I’ve watched my bracket crumble. Seven people filled out brackets in our (ego-only) pool this year. The chart below is sorted by the number of possible points remaining which seems like the best way to compare teams. AndyB is leading the charge with Jay and Logan close behind him. Tim failed to pick a winner of the final game (that game is worth 32 points) but he still has more possible total points than Jim and Andy!

Book Quotes

There were too many good quotes to fit them all into yesterday’s post. Here’s another batch.

The Evolutionary Void (Commonwealth: The Void Trilogy) by Peter F. Hamilton

  • We all regard the past too highly. We should cut ourselves free of it. You can only ever look forward to the future.”
  • Most people who have failed miserably in life itself have one last resort left available to them. They become politicians.

American Icon: Alan Mulally and the Fight to Save Ford Motor Company by Bryce G. Hoffman

  • The young boss realized that his job was not to show his subordinates how much smarter he was than they were, but to bring them up to his level.
  • Failure is only the opportunity more intelligently to begin again. —HENRY FORD
  • When you get a whole country—as did ours—thinking that Washington is a sort of heaven and behind its clouds dwell omniscience and omnipotence, you are educating that country into a dependent state of mind which augurs ill for the future. —HENRY FORD
  • “You have to expect the unexpected, and you have to deal with it,” he said. “Whining is not a plan. Wallowing is not a plan. We have a plan, and if we need to adjust it, we will.”
  • Washington was now spending taxpayer dollars to pay for advertising touting the benefits of GM and Chrysler products over competing Fords. Those companies were also using taxpayer dollars to offer bigger incentives in an effort to win back sales. Even more troubling for Ford was the fact that the government was using General Motors’ former lending arm, GMAC, to offer attractive financing terms to buyers that Ford simply could not match.
  • The leader’s job is to remind people of that vision, make sure they stick to the process, and keep them working together.

WAR by Sebastian Junger

  • Apaches have a 30 mm chain gun slaved to the pilot’s helmet that points wherever he looks; if you shoot at an Apache, the pilot turns his head, spots you, and kills you.
  • Good leaders know that exhaustion is partly a state of mind, though, and that the men who succumb to it have on some level decided to put themselves above everyone else. If you’re not prepared to walk for someone you’re certainly not prepared to die for them, and that goes to the heart of whether you should even be in the platoon.
  • We sleep soundly in our beds because rough men stand ready in the night to visit violence on those who would do us harm. —Winston Churchill (or George Orwell)
  • The only way to calm your nerves in that environment was to marvel at the insane amount of firepower available to the Americans and hope that that changed the equation somehow. They have a huge shoulder-fired rocket called a Javelin, for example, that can be steered into the window of a speeding car half a mile away. Each Javelin round costs $80,000, and the idea that it’s fired by a guy who doesn’t make that in a year at a guy who doesn’t make that in a lifetime is somehow so outrageous it almost makes the war seem winnable.
  • “Combat is such an adrenaline rush,” he says. “I’m worried I’ll be looking for that when I get home and if I can’t find it, I’ll just start drinking and getting in trouble. People back home think we drink because of the bad stuff, but that’s not true… we drink because we miss the good stuff.”
  • The most traumatic things about combat is having to give it up.
  • Men say they miss combat, it’s not that they actually miss getting shot at—you’d have to be deranged—it’s that they miss being in a world where everything is important and nothing is taken for granted. They miss being in a world where human relations are entirely governed by whether you can trust the other person with your life.
  • Statistically, it’s six times as dangerous to spend a year as a young man in America than as a cop or a fireman, and vastly more dangerous than a one-year deployment at a big military base in Afghanistan. You’d have to go to a remote firebase like the KOP or Camp Blessing to find a level of risk that surpasses that of simply being an adolescent male back home.

Brain Rules for Baby: How to Raise a Smart and Happy Child from Zero to Five by John Medina

  • I had deep feelings for my son—always will—but I wondered at the time what ever made me decide to have a baby. I had no idea that something so wonderful was also going to be so hard. I learned a difficult but important lesson: Once a kid comes into the world, the calculus of daily living coughs up new equations. I am good at math, but I was no good at this. I had no idea how to solve these problems.
  • The baby takes. The parent gives. End of story.
  • When I lecture on the science of young brains, the dads (it’s almost always the dads) demand to know how to get their kids into Harvard. The question invariably angers me. I bellow, “You want to get your kid into Harvard? You really want to know what the data say? I’ll tell you what the data say! Go home and love your wife!” This chapter is about that retort: why marital hostility happens, how it alters a baby’s developing brain, and how you can counteract the hostility and minimize its effects.
  • Couples who regularly practice empathy see stunning results. It is the independent variable that predicts a successful marriage.
  • For all of us, nature controls about 50 percent of our intellectual horsepower, and environment determines the rest.
  • There are four nutrients you will want in your behavioral formula, adjusting them as your baby gets older: breast-feeding, talking to your baby, guided play, and praising effort rather than accomplishment. Brain research tells us there are also several toxins: pushing your child to perform tasks his brain is not developmentally ready to take on; stressing your child to the point of a psychological state termed “learned helplessness”; and, for the under-2 set, television.
  • Along with the ability to regulate emotions, the ability to perceive the needs of another person and respond with empathy plays a huge role in your child’s social competence. Empathy makes good friends.

Book Quotes

I’ve been reading a lot of good books lately thanks to Good Reads. Here are some of the quotes that I’ve highlighted while reading them on my Kindle.

Pandora’s Star (The Commonwealth Saga) by Peter F. Hamilton

  • He never did understand why people collected or even admired art; the greatest human artist could never hope to match what nature did with a single flower.
  • That’s the thing with serious money, you can do so much that you never have time to do anything.
  • Ozzie knew just how much truth there was in the old saying that every conservative is another liberal who got mugged.

Si-cology 1: Tales and Wisdom from Duck Dynasty’s Favorite Uncle by Si Robertson

  • When you were born and they were handing out brains, you thought they said ‘trains’.
  • Christine was ready to have a baby, so she really wanted me to visit the doctor to find out what was going on. I wanted to have children badly as well, so I agreed to go. After an examination, the doctors thought my sperm count might be low. They handed me a glass jar and told me to bring back a specimen the next day. Now, I’m not going to lie. I didn’t feel comfortable doing it. Despite my embarrassment, I agreed to come back with a specimen. The next day, I returned to the doctor’s office. “Where’s the sample?” the doctor asked me. “Hey, I tried to do it,” I told him. “But no matter how hard I tried, I couldn’t do it. I asked my wife for help, but I still couldn’t do it. Then I asked my neighbor to help me, and I even asked my army buddies for assistance. No matter who helped, I couldn’t do it.” I looked at the doctor and his face was bright red. “Hey, none of us could get the lid off the jar,” I said.

Unbroken: A World War II Story of Survival, Resilience, and Redemption by Laura Hillenbrand

  • In World War II, 35,933 AAF planes were lost in combat and accidents. The surprise of the attrition rate is that only a fraction of the ill-fated planes were lost in combat. In 1943 in the Pacific Ocean Areas theater in which Phil’s crew served, for every plane lost in combat, some six planes were lost in accidents. Over time, combat took a greater toll, but combat losses never overtook noncombat losses.
  • In one time frame, in the Eastern Air Command, half of the Catalina flying boats attempting rescues crashed while trying to land on the ocean. It seems likely that for every man rescued, several would-be rescuers died, especially in the first years of the war.

The Name of the Wind: The Kingkiller Chronicle: Day One by Patrick Rothfuss

  • When we are children we seldom think of the future. This innocence leaves us free to enjoy ourselves as few adults can. The day we fret about the future is the day we leave our childhood behind.
  • If there is one thing I will not abide, it is the folly of a willful pride.
  • My parents danced together, her head on his chest. Both had their eyes closed. They seemed so perfectly content. If you can find someone like that, someone who you can hold and close your eyes to the world with, then you’re lucky. Even if it only lasts for a minute or a day.
  • There are two sure ways to lose a friend, one is to borrow, the other to lend.

The Wise Man’s Fear: The Kingkiller Chronicle: Day Two by Patrick Rothfuss

  • Books are a poor substitute for female companionship, but they are easier to find.
  • Everyone knows a man’s reputation except the man himself.
  • Nothing in the world is harder than convincing someone of an unfamiliar truth.
  • Trying to have a conversation with him was like playing catch with a well.

Dominion

There are a lot of board game fans at work. They buy pretty much every game that comes out and give it a whirl. A year or two back, I asked some of them what would be a good next game now that we’re getting a bit played out of Settlers and Carcassonne. The common answer was Dominion. This was our first foray into card-based games and the first couple times we played it were pretty rough, confusing and slow. But lately we’ve really grown to love it and have been choosing it more and more. Every game is different depending on which 10 action cards you use for the game. That’s fun and frustrating at the same time. We’re not yet good enough to read the cards and know what strategy will fit them best. If we play two games with the same deck of cards, the second go-round usually has a lot more intentional play behind it. If you’re looking for a good game to add to your collection, consider Dominion!

And if that all seems a bit too much, some of our other favorites are Bohnanza and Alhambra.

FT Delta Maiden Flight

My second RC plane is an FT Delta built from a kit from the FliteTest.com store. This one uses the same “power pod” as my first plane. The power pod consists of most of the electronics – motor, speed control, receiver, and battery. The pod just pops off the first plane and straps onto the second plane. That saves a lot of money and makes it really easy to try multiple planes.

This plane only has two control surfaces at the back of the wing. They’re either ailerons or elevators depending on your perspective, but on the transmitter, you set the two to be combined. It’s called “elevon mixing.” So whether you’re going left, right, up or down, those two control surfaces do whatever they need to do to point you in the right direction.

While building this one, I covered the whole thing with Minwax to protect it from getting wet and also filled in the edges of the cut foam with hot glue. I made an attempt at painting the plane too. It looks ok from a distance.

So how did the first flight go? I made it about 10 feet and crashed. Second flight? Same thing. Turns out I had left and right reversed on my setup and didn’t notice it. Luckily this plane is a tank and other than some broken props which are cheap to replace, the plane was completely fine. I crashed a few more times that day. Some of them were because I was trying things I wasn’t ready for (like inverted flight) and later in the day the prop seemed to be popping off. My theory is that the motor got some mud in it and wasn’t spinning properly so I took it home and gave it a good cleaning.

Hopefully I’ll get this back out to the park soon and spend some more time with it. It’s significantly faster than the FT Flyer and it’s a lot more nimble too. It’s a good next step in my RC learning process.
