On Groups

Every once in a while, take a step back and think about “What groups of things am I working with?”

For example, Twitter. You can follow lots of people, but it doesn’t always make sense with people from your different interests (work, friends, family, celebrities, bands, news, restaurants) to be intermashed. So, you’ve got lists.

Same thing happens in biology, “Hey these things all look/act the same”. From this simple idea, Darwin achieved fame and changed the world.

It’s an obvious thing, but people often don’t take that moment. Take the time to step back and say “what are the basic groups of things I’m seeing / activities I’m doing”.

It helps find larger trends, and as soon as you deal with groups, you can find shortcuts and optimizations. Imagine how little you would get done if your visual system identified every object in a group.

Assuming you are not Rainman, and also assuming you are not a gardener or landscape architect, you see “a house with a bunch of bushes in front”, and not “a house with 19 evenly spaced plants in front of the sidewalk, two on either side of the doorway, 7 around the lamppost…” Your visual system automatically groups objects to serve as a mental shortcut.

Of course, there are benefits to being specific, as well.

Why there is a lobster carved into the Notre Dame Cathedral

Wow, Internet. You are fast. Specifically, Nina is fast. Good job also to Michael, Jason, and Jessica.

The other day I asked “Why is there a lobster carved into the Notre Dame Cathedral?“. Turns out that it’s not exactly a lobster — it’s a crab.

Notre Dame exit

The door that they now use as the exit of the cathedral is called the Portal of the Virgin, and the panels around it represent the cycles of earthly life. The “lobster” is Cancer the Crab, and represents June.

One thing that came up often is the idea that the symbolism of the lobster might have something to do with the fact that it used to be a poor man’s food. It turns out that is true, but only in North America. When Europeans first started coming here, lobsters were everywhere along the coast. It was easy to harvest them, so poor families who didn’t have other options for food would go out to the water and bring them home. Over time, lobster became known as a food for the poor.

In Europe however, people were really into them. The Romans used them as subject matter in the arts and the Turks used their shells as inspiration for armor. Lobsters were widely used for treating inflammation of the eye, stomach aches, epilepsy, kidney stones, and other urinary conditions. In France, a type of lobster called the Royal Blue was eaten by the upper class families, and they even had artists depict them eating lobster.

So, when they were building the cathedral, people were really into Nature, which is reflected in the belief in Zodiac signs, and that’s why it surrounds one of the main doorways.

Learning is awesome!

Defaults Account for Most of Pared Down Debt – WSJ

There are two ways, though, that the debts can decline: People can pay off existing loans, or they can renege on the loans, forcing the lender to charge them off. As it happens, the latter accounted for almost all the decline.

Why is there a lobster carved into the Notre Dame Cathedral?

Since Google Answers got shut down, this is the next best thing.

I will pay $20 to the first person that can bring me two or three good citations explaining the significance of the lobster that is carved into the Notre Dame Cathedral. It’s on the outside, to the top right of the exit. It is very prominent. What’s up with it?

Notre Dame Carvings...Avec Lobster

Yes, I’ve tried googling for the answer. I’ve also asked historians and the few French people who I personally know. None of them have any clue as to why it is there.

Help me, Internet. You’re my only hope.

The whole internet has been worth it

I just had the following interaction with Comcast via Twitter. I will give them this — I appreciate that they’re using Twitter for customer support, and I’d love to see more companies do this. It does take a modern attitude to put support out in a public space where people can make fun of their missteps. Like this one:

“took care of the adjustments” huh? Guess I don’t have to pay bills anymore. Thanks Comcast! <3

It’s all about the Benjamins, baby.

It is a very long time ago in a farming town. Andrew, Ben, and Charlie are farmers who live on the same road, who all know and trust each other. Ben has a problem with his tractor one day, and happens to mention it to Andrew. Andrew offers to check it out — he’s fixed his own tractor many times and might be able to help Ben out. They go over to Ben’s house, and sure enough, the fuel filter is clogged up. Being on a farm, Andrew is resourceful enough to be able to clean it out. When he puts everything back together, the tractor fires up right away.

“Thanks Andrew!”, Ben says. “Let me tell you what. If it weren’t for this, I wouldn’t have been able to properly harvest my wheat. When the harvest comes this fall, I’m going to give you 10 extra bushels of wheat. Let me give you a note so that I don’t forget.”

Next week, Charlie is over at Andrew’s farm for a visit. They’re walking around together, talking about their respective farms, and wondering if anyone will ever invent Genetic Engineering to help improve crop yields (since it is a very long time ago). It is a sunny day, and Andrew notices Charlie’s hat. “Darn, Charlie. That is a very nice hat.”

“Thanks Andrew. I made it myself. Took a while, but it’s really nice to keep the sun out of my eyes.”

“I could use a hat myself, but I’m so busy with my farm, I just don’t have the time. Say, you could use some extra wheat, right?”

“Yeah, like everyone else in town, we love to bake bread, and could always use some extra wheat. Why do you ask?”

Andrew explains to Charlie how he had fixed Ben’s tractor, and as a token of appreciation, Ben promised to give Andrew 10 bushels of wheat. “Look Charlie, we both know Ben is a great farmer, and a stand up guy. He’ll definitely harvest enough wheat that there will be 10 extra bushels. He wrote his promise down on this note so that we wouldn’t forget. What if I give you the note, and when fall comes, we’ll have Ben give you the 10 bushels of wheat instead? Would you make me a hat now?”

Charlie agrees, and Andrew hands over Ben’s note. So that everyone is clear on what happened, Andrew writes an explanation on the back of the note, and signs his name as proof that it is official.

Ben is a social guy around town, and especially proud of his new hat, is out quite often. As farmers do, they talk about their farms, and occasionally people offer Ben advice or help. Being a nice guy, he often offers bushels of wheat as thanks to people who help him. He always comes through with the wheat, and does it so often that everyone in town has heard of this practice.

It becomes so common that when other townsfolk want to show each other appreciation for a favor done, they will sometimes give the other person one of Ben’s notes, which by now fill their pockets. When fall comes, everyone meets at Ben’s farm to say hello, and cash in their notes, which by now have gotten their own slang — they are called Benjamins. After receiving their share of the bushels, the townsfolk go directly home and start baking bread — a day that after many years becomes known as “dough day”. For the rest of the season, their town always smells like fresh baking bread.

Our own worst enemy

Low quality demand, then, means that we buy cheap, but the price is invisibly steep: it ignites a global race to the bottom, what a complexity economist might call a dynamic equilibrium of negative consumption externalities, consumption that results not just in joblessness but a loss in the quality of jobs. The quality of a job is sparked by higher quality demand; or, valuing more than just the dollar price of a thing, but also its human and social impact. When we have low-quality demand, we have low-quality jobs. When we value McDonalds, the result is McJobs.

Drum Fills

Now that I’m settled in SF, I’ve had some time to practice drumming. For my neighbors’ sake, I have an electronic kit.

I re-realized something about drum fills and wanted to share it with the internet. FYI: Fills are the part where instead of keeping the beat, you hear a whole bunch of notes played all at one, usually followed by a cymbal.

Sticking fills is basically like sticking rolls, except a roll is a constant “right, left, right, left, right” — played really quickly. Fills usually involve more than just the snare drum, but that doesn’t really matter for what I’m talking about. I’m talking about sticking — the pattern of lefts and rights (L and R).

RLRL == "hit with your right hand, your left, your right, your left with no empty time"

That’s how you’d write a roll. A fill might be written

RLR RLR RL LRLR == "play three notes, silent for one note, then play three more,
another silent note, two more, another silent, then four more "

Normally drummers count in “1 2 3 4, 1 2 3 4”, but when counting fills and rolls, I’ve found it easier to switch from counting the beat to counting the number of notes in the fill or roll, then switching back to counting the beat. So, the above one would get counted like

1 2 3 (pause) 1 2 3 (pause) 1 2 (pause) 1 2 3 4

Hope it helps you. Rock on.

Unhappy truths and hollandaise sauce.

I went out to breakfast yesterday, and ordered eggs benedict. It showed up looking delicious, except the English muffin was slightly burned. I dug in because I was hungry, and when the server came by to see if everything was good, I nodded yes for the same reason. I should have said something, but between the hunger and lack of desire to complain, I didn’t.

In business, even though people should tell you unhappy truths, they don’t. When you get feedback, pay attention.
