Last week I turned 39 years old. A few people pointed out that next year will be the big four-oh, but I see more significance in this birthday as a milestone delineating the portions of my time on earth.
Halves: if I have a typical lifespan, this moment is just about the halfway point of my life! That striking observation has me taking stock of things.
I hesitated to write this as many of my friends reading this are older than me and it implies that their lives are mostly over. But me not writing it doesn’t change that. It feels right to me to acknowledge the finitude and preciousness of life, whatever age one is.
Thirds: this accounting neatly renders my life into three acts of twenty-six years each. Which works out perfectly in my case: I had my first child at 26 years old and my youngest child will become a legal adult when I’m 52.
That makes a third of my life without children; a third of my life as a parent of young, at-home children; and a third of my life with adult children. This midpoint of my life is also the halfway mark of me having children at home.
Quarters: a quarter of this life would be nineteen-and-a-half years. That interval coincides with the two biggest lifestyle changes I’ve made, both related to diet.
Olúfẹ́mi O. Táíwò made this lovely remark on a podcast episode:
A lot of these people that we rightly respect and revere in organizing circles were just regular people who had the very unregular thought that they could do something about the world around them. And who just decided to do it.
And it’s stuck with me, so I’m memorializing it here. It’s dead-on.
The most recent time I thought of it was last week, when catching up with a friend at Workantile. He had organized a group buy of solar panels for his neighbors and, in the process, learned that his subdivision’s homeowners association (HOA) bans solar panels that are visible from the street. The reason? They’re aesthetically unpleasing and will damage property values.
He then had the unregular thought that he could do something about that. So he looked into what it would take to get that rule removed. That led him to power mapping, and in particular, the HOA board of directors. And he found that no one has ever been elected to this HOA board. The member meetings never make quorum, so all board vacancies are filled by appointment. By the board. Pretty unhealthy governance.
Now he’s looking at doing something about that. That’s a bigger challenge and a very boring way to fight climate change. But it’s the right thing to do. And it’s possible, with a big enough dose of unregular thinking.
I send love and solidarity to everyone who sees something that could be better and instead of tolerating it, says, I could do something about that. And just decides to do it.
I am reading (like many people) Four Thousand Weeks. That and other similar resources have sharpened my awareness of how little time we have when compared to all the things we could do.
That feeling is especially acute right now, in March. This is when some of my favorite seasonal events happen:
Building a luminary for Ann Arbor’s FoolMoon festival
I’ve done all of those things at various times in the past. Never all in the same year, tellingly. Maybe it’s the pull of the longer days and warmer weather that has me wanting to embrace all of these March traditions at once.
I’ve been doing a lot of “mental blogging”, no actual blogging, so here’s an attempt to break that and get something written.
Skateboarding is suddenly popular around here. As a family, we watched the 2021 Olympics skateboarding: all of the women’s final and the condensed version of the men’s final. My kids were surprisingly into it. It probably helped that the women’s winners were so young – the gold medalist was just 13 years old.
That got them interested in skating themselves. We purchased a kid’s board last year, during the height of COVID, but it soon got shelved. It was a nice board, too. The one I’d learned on as a teen had low-quality bearings and I could hardly coast on it, which made it a lot less fun. I compensated for that experience by buying my kids a good starter board. It’s out of the garage and rolling again.
Speaking of my experience, I’m interested in skating again, for the first time in twenty years. I dabbled during my teens, logging maybe a couple of dozen hours on skateboard and longboard before giving up. I remember walking to the park in the summer and practicing my ollie by myself. And just not getting it. Between a lack of progress and having no friends who skated, I soon called it quits.
I continued to enjoy the aesthetics of street skating, though. I got most of the way to completing every achievement in the Tony Hawk Pro Skater 2 – “considered one of the greatest video games of all time, as well as the highest-rated sports video game” – searing the soundtrack into my brain (“lights out, guerilla radio!”). And I watched skating videos, rarer in the pre-YouTube days. Rodney Mullen was my favorite.
Fast forward two decades and it’s easy to rediscover his highlights. Here’s a nice reel; I’m starting it at my favorite kind of trick, with elegant manuals and grinds on street objects:
Is it too obvious to compare him to a ballet dancer?
All of this has been enough to get me back on a board. I bought one off Craigslist this week along with some safety pads. I’m hopeful that I’ll learn more quickly this time around. I had terrible balance as a kid, but since then I’ve done a ton of cycling and fair amount of snowboarding and skiing, so I think I’ll be better. Plus many years of learning new things has made me wiser and more patient. I’d love to be able to ride well, manual, and (stretch goal) ollie over something small.
We’ll see how it goes. If nothing else I’ll have some fun outdoors with my kids.
Next month, if all goes well, Ann Arbor will be overrun by millions of Magicicada septendecim, the seventeen-year cicada. I am giddy with anticipation.
Why am I so excited? I think the cicadas are arriving at just the right moment in my life, in terms of both time and biophilia.
The timing is fortunate. At 3, 6, and 10 years old, my kids will be old enough to appreciate the insects and still young enough to feel wonder. My oldest is already on board: she amassed a collection of cicada shells from more regular “annual” cicadas that emerged in recent years. The next time these cicadas emerge, my kids will be grown, and I may be an empty nester. My oldest will be the age I was when she was born.
I’ve experienced periodical cicadas twice so far, in both cases Brood XIII in Chicago. I was 6 in 1990 and vaguely remember the insects’ ubiquitous noise and bodies. When that brood resurfaced in 2007, I was 23, and have no memories of cicadas from that year. I lived in a 24th-floor apartment in downtown Chicago – maybe there was too much concrete to support any cicadas. I remember my friend Boyu, who was working in the western Chicago suburbs over the summer, telling stories of brushing his car off before getting in and still ending up with cicadas inside. But for the timing to work, I think that would have been stragglers emerging off-year in 2003, which I would have missed in the city.
Now the reverse is true: I’m in the right part of the state for this year’s Brood X emergence. Much of Michigan will miss the cicadas, but Ann Arbor should be as reliable a place as any to experience them.
This will be my third visit with periodical cicadas. Brood X will next emerge in 2038 (I’ll be 54), 2055 (71), and 2072 (88, if I last that long). After this summer, half of my cicada seasons will be behind me.
The cicadas are also coming at the right time for me to appreciate them. In the last year or two I’ve become more appreciative of, knowledgeable of, in love with the natural world. I’m learning about animals, trees, and as much of life on this wondrous planet as I can, cultivating my biophilia. It blew my mind to learn about oak trees evolving to have mast years, where in some years they sync up and together produce an unusually-large crop of acorns to overwhelm predators. Periodical cicadas have evolved a similar mechanism of using staggered timing to their advantage: when they emerge in such great numbers, predators can’t eat them all.
What an incredible feat of evolution, to lie in wait for seventeen years and emerge in concert! I find that outcome especially neat given that at this point, they only reproduce as often as humans do. When the parents of this year’s Brood X cicadas walked the earth, George W. Bush was still president. They wait so long for just a short couple of months above ground. It reminds me of tree time or rock time, timescales slower than our human experience. This strategy has been slowly optimized over millions of years. What to me is a rare, long-awaited, blog-worthy event is just the next repetition of their experiment.
I feel lucky to be living in the right place and right moment for this event. It’s a six-in-a-lifetime occurrence and I don’t even have to leave my neighborhood to enjoy it. This weekend, I’ll pick up a book on cicadas from the library to prepare myself, and look forward to May and June. May this brood be as thick and deafening as ever.
One thing led to another. In early 2016, I was participating in discussions on the #rstats Twitter hashtag, a community for users of the R programming language. There, Andrew Martin and I met and realized we were both R users working in K-12 education. That chance interaction led to me attending a meeting of education data users that April in NYC.
Going through security at LaGuardia for my return flight, I chatted with Chris Haid about data science and R. Chris affirmed that I’d earned the right to call myself a “data scientist.” He also suggested that writing an R package wasn’t anything especially difficult.
My plane home that night was hours late. Fired up and with unexpected free time on my hands, I took a few little helper functions I’d written for data cleaning in R and made my initial commits in assembling them into my first software package, janitor, following Hilary Parker’s how-to guide.
That October, the janitor package was accepted to CRAN, the official public repository of R packages. I celebrated and set a goal of someday attaining 10,000 downloads.
Yesterday janitor logged its one millionth download, wildly exceeding my expectations. I thought I’d take this occasion to crunch some usage numbers and write some reflections. This post is sort of a baby book for the project, almost five years in.
By The Numbers
This chart shows daily downloads since the package’s first CRAN release. The upper line (red) is weekdays, the lower line (green) is weekends. Each vertical line represents a new version published on CRAN.
From the very beginning I was excited to have users, but this chart makes that exciting early usage seem miniscule. janitor’s most substantive updates were published in March 2018, April 2019, and April 2020, with it feeling more done each time, but most user adoption has occurred more recently than that. I guess I didn’t have to worry so much about breaking changes.
Another way to look at the growth is year-over-year downloads:

Here are some plans and ideas for this year. I’m late, in the sense that this would be a better January post, but no regrets – that’s mostly because I’ve been doingsome of this already.
Professional: this is my biggest change in 2021! I left my past job analyzing education data and began this month as a Data Analyst at the City of Ann Arbor. It’s an exciting opportunity: subject matter I’m passionate about, work that will challenge me technically, building new relationships, and heeding the call of public service. And if/when we eventually go back to working in-person, city hall is a short bike ride away.
The change is a big leap in a lot of ways. Two major ones are returning to an individual contributor role after years of managing and shifting from the rhythms of consulting to those of government.
For years I’ve said my dream job was to do municipal data science, like the big teams in NYC or Chicago or Los Angeles, but here in Ann Arbor. This is as close to that dream as it gets, which is pretty incredible. I’m still getting up to speed (yesterday was day 8) but it looks like there’s no end of interesting work to do.
In July I predicted that there would be no in-person instruction for Ann Arbor Public Schools this entire school year. Unfortunately, that prediction is looking accurate. Let’s start planning for September 2021.
The discussion among the district, board, and parents seems focused on reopening this year. At what level of disease activity, and which safety precautions, would be enough for kids to begin going to school? At least, that seemed to be the discussion a month ago, when disease levels were lower and other districts in SE Michigan (including some in Washtenaw County, like Saline and Dexter) were sending kids to school.
Especially with the current COVID surge now shutting down those other districts, it seems likely that reopening this year is not in the cards for Ann Arbor Public Schools. Given that, I fear we’re wasting precious time and energy debating possibilities and metrics for reopening this year. It echoes what happened this summer, when time spent considering possibilities for in-person instruction would have been better used on improving systems for remote instruction.
Today I remember Eyedea, aka Micheal Larsen, who died ten years ago. “Who’s the best rapper ever?” is an unanswerable question, but when it comes specifically to freestyling, Eyedea is the Greatest Of All Time.
As a hip-hop-loving teen in the early 2000s, I traded Eyedea’s mp3s on peer-to-peer sharing services like Napster and KaZaa. He was only two years older than me and yet by 18 he had already vanquished all comers to become the undisputed champion of battle rap. He got bored of battling and moved on, but his freestyles never got old to me. Here are some of my favorites, both battles and whimsical freestyles. If you never heard them, you’re in for a treat. Even a layperson can appreciate the greatest of all time putting on a master class, in anything.
Battles
CityPages has a list of five great Eyedea battles, with embedded videos. The first one listed, from HBO’s Blaze Battle tournament in 2000 (which Eyedea won), is a classic. When his opponent starts dancing to distract him, Eyedea immediately builds his final rhymes around that: “this cat wants to be my backup dancer!”
This is the best part of Eyedea’s freestyles: they’re so clearly extemporaneous. So many recordings and appearances billed as “freestyles” are obviously pre-written. No surprise, as even skilled rappers struggle to make up decent rhymes entirely on the fly. Eyedea’s flows are indisputably improvised, as shown by his ability to respond to opponents in battles (and friends in cyphers).
Friendly freestyles
The greatest freestyle session ever recorded is also a settled matter: the 2000 KFAI Orphanage freestyle. Here’s Blueprint’s description of the legendary session, but more importantly here’s the recording: 45 glorious minutes of freestyles, as indie rap icons trade the mic back and forth.
I write this during the Jewish holiday of Sukkot. “Sukkot” is the plural of sukkah, the temporary hut that Jews construct for the fall harvest holiday.
I had an epiphany this year: build the sukkah out of buckthorn! Common buckthorn is an aggressive invasive species that plagues the city of Ann Arbor, the state of Michigan, and the Great Lakes region. Since a friend showed me some growing near my house, I notice it everywhere and take pleasure in removing it, as outnumbered as I am in that fight. I’ve cleared it at my previous home in Scio Township, at my in-laws in East Lansing, and now pull it from city parks.
A sukkah needs a roof of s’chach, or cut plant matter. Buckthorn is perfect for this: it’s slender, long, and leafy. In fact, it could do double-duty: it’s ideal for the roof but larger, thicker specimens could also make up the frame of the sukkah (which can be reused from year to year). At the end of Sukkot, the buckthorn can be disposed of in municipal compost carts, where any berries will be destroyed in the heat of the city’s compost piles.
