    What I care about vs. what I write about

    I’m disappointed with the misalignment between what’s important to me and what I write about here.  Here, I acknowledge and explore that.

    What I care about: meaningful, exciting, or useful ideas

    I have a list of substantial, interesting topics I’ve meant to write about.  Some are still relevant, others have drifted behind me as missed opportunities (e.g., I meant to discuss the August 2018 Ann Arbor Democratic primary elections).  Some are years old, others freshly sparked from recently conversations.

    Some of these topics are explored in abandoned drafts.  Others manifest on paper as just a single bullet point, albeit with hours of associated reflection and many references ready to go in my head.

    These more meaningful topics demand focus and time, which I have in only limited supply.  Such posts are also probably better when well-researched, which requires more time – though I’m growing suspicious that the burden of assembling links may not be worth it if it paralyzes me.  And I question whether it’s my place to write on them. Is my opinion valid? Do I know what I’m talking about?

    What I then write about: trivial, dull matters.

    Meanwhile, as these ideas languish, look at some of the blog posts I did manage to write in 2018.  I ranted against the TrailKeg, a thneed.  I wondered if old yard sign frames could be welded into a Papasan chair.  I wrote a how-to based on what I learned when configuring a specific model of solar panel monitoring gateway.

  • Studded bike tires for winter cargo biking

    I love biking and hate driving. Thus I try to bike as much as possible. Biking in the cold is easy enough, you just bundle up the right way. The only truly specialized product needed is pogies. I install my winter accessories on my e-assist cargo bike, which I can use for solo commuting but also ferrying children and fetching groceries.

    This served me well until the current set of snow-thaw-freeze cycles in Ann Arbor. Water runs onto previously-clear streets from uphill snowbanks; this turns into ice at night.

    Going downhill on Madison St last week, I wiped out hard on black ice, sliding sideways (along with my bike) down the icy pavement. Fortunately I was alone, and only bruised my elbow and my pride. This was my first fall since I started tracking my distance biked, so 2,900+ miles. I was riding a Yuba Boda Boda with relatively-wide 2.15″ Freedom tires – good grip by summer standards, but useless on ice.

    That spill was enough for me to try studded tires. I put a 26″ Kenda Klondike on my front wheel. And the difference has been remarkable. I now feel my back tire sliding, but can recover from that; meanwhile, my front wheel grips the ice.

    This morning I went through West Park, where snowmelt had coated the paved path in shiny ice for stretches of 10 feet at a time. No slipping! Ditto when navigating the bumpy ice ruts that have established themselves on my street in the last month. I’m riding both cautiously and with delight.

    My verdict thus far is yes, studded tires make safe year-round biking possible! And that a single studded tire, on the front, is a big improvement from none (the internet had suggested this, but not unanimously).

    My studded rear tire was a special order item because my bike has a 20″ rear wheel. The Schwalbe Winter Marathon is on its way and I’ll be installing it immediately upon arrival.

    The studded tire makes a crackling sound, which I don’t mind except that it makes it hard to hear my kids on the back of the bike at speeds above 15 mph. It seems to grip clear pavement well, and while it’s designed for ice, the knobby tread is an improvement for navigating snow compared to the road-style tread of my Schwalbe Marathons.

    And while it seems to slow the bike a little, I’m running these tires on an e-assist model, so that’s not a problem.

    Speaking of which: studded tires and cargo bikes seem like the perfect pairing. Cargo bikes are already slow and heavy; they are costly, with the expense of studded tires relatively low in comparison; and they transport children, not just a single carefree rider, so safety is paramount. (And the bike looks more gnarly on studs).

    I am surprised not to see more cargo bike purveyors pushing studded tires. Perhaps the cargo-biking demographic is more likely to just leave the bike at home when it gets icy?

    Configuring Enphase Envoy for wifi without ethernet cord

    This is a how-to for connecting your Enphase Envoy (the oval one with the LCD screen) to connect to a home Wi-Fi network, without using an ethernet cable or the Enphase Installer Toolkit app.

    Enphase’s how-to guides give you about 80% of the information you need to do this, below are notes on things I figured out to fill in the other 20%.  Their guidance is geared toward installers, while this post is for homeowners who want to connect their Envoy to the home Wi-Fi network and don’t have a WPS button on their router or need to use another option.

  • The future of the People’s Food Co-op

    MLive reports that the People’s Food Co-op is in financial trouble, having lost money since 2012.  I joined PFC shortly after moving to Ann Arbor in 2009 and have been a supporter and shopper since.  Here are my thoughts.

  • Should I stop flying?

    Summary: I like riding in airplanes and to me, it’s normal.  And I’m under social pressure to fly.  But when I confront the science of climate change, air travel seems immoral.  Should I stop?  Will I stop?


    I’m writing this because it’s been on my mind and:

    1. Posts & articles are typically about “this thing I did” not “something I’m considering.”  I want to show that making decisions is messy.
    2. If I decide to stop flying, which may seem drastic, this will show I was considering it…
    3. … and if I keep flying, this will show I considered it – which could make me look thoughtful, or more likely, weak and unprincipled.

    Why

    The climate situation is dire.  I can’t overstate this.  Read coverage of the most recent (Oct 2018) IPCC report and/or Joseph Romm’s book Climate Change: What Everyone Needs to Know.  Humanity is on pace to destroy the world.  And the worst polluters are well-off Americans like me.  Because we do high-carbon luxury things that most of the world can’t afford.  Flying is one of the most-polluting activities.

    Upcycling yard sign frames into a papasan chair?

    Filed under “ideas I’d pursue if I had infinite time:” could I weld the metal wickets from old political yard signs into the bowl of a papasan chair?  There are tons of signs rendered useless each election when a candidate loses or a proposal is decided.  These are free or nearly-free, and indeed many are left by the side of the road to rust.

    The thin metal rods bend well.  I imagine giving them the proper curve, then welding a grid of them into a bowl shape.  Welding is on my long-term to-learn list, perhaps in 2019.  Would this be an easy trial project or a foolishly hard one?  It would at least be low stakes.

    I’m not sure what material the rods are.  Galvanized steel?  I’ve seen some of them rust.  If galvanized, I gather additional safety precautions may be in order from zinc fumes that off-gas during welding.

    Someday, perhaps.  I wonder if it’s been tried, or what else people have made from this source of free metal rods.

  • Fully-remote jobs don’t need in-person interviews

    I hired a data analyst last year who started working for me in December.  He lives in Colorado, I live in Michigan.  After 10 months of working together, week in and week out, I finally “met” him at our annual company conference last month (September).  Does that seem funny?  I was surprised by how tall he was, but otherwise, no, it’s business as usual around here.

    I’ve now embraced the idea of hiring someone and working with them without first meeting them in person.  If you’ll be working with them remotely, and your team and organization have the right culture and systems in place for that, why would you insist on in-person interviews?

    In a truly remote-first organization, there’s little cause to fly someone out for an in-person interview.  And there are many reasons not to.  When you weigh the costs and benefits, it’s not worth it.  You’re a remote organization – embrace it!

  • The cargo bike changed my life

    In the summer of 2016, I was visiting Brooklyn for work.  Walking down Fulton Mall during morning rush hour, I saw a man pedaling through traffic with his school-aged daughter perched on the back of his bike, her feet resting on running boards.

    I had never seen such a thing and couldn’t get it out of my head.  I did some research online, searching terms like “bike transport kids running boards” and encountering the proper name: cargo bike.  When I found myself back in NYC a few months later, I stopped by 718 Cyclery, talked to Joe, and ordered a Yuba Boda Boda.

    That bike changed my life.  Let me count the ways:

    My health

    My bike before the Boda Boda was an old hand-me-down Trek hybrid that I neither took care of nor rode much.  At most maybe a 3 mile commute a few times per month in the summer.

    DIY Hops Trellis

    I started growing hops at my parents’ home in Chicago in 2008.  In the summer of 2011 we moved them to Michigan and I built this trellis:

    hops trellis
    Hops grow from the frames on the right up the lines to the tree on the left

    Now that it’s time for the trellis to find a new home, I’m writing up my design for posterity.  Notable aspects include that it can be harvested without ascending a ladder and that the top is mounted on a tree.

    Each of the three hop plants (Cascade, Mt. Hood, Centennial) has its own starting frame.  It runs up the yellow chain for 5 feet, then starts climbing a line up into the trees:

    Overgrown vegetation shows I’ve lost interest

    Batch 79: 2016 Dry-Hopped Plymouth Orchards Cider

    Started with 5 gallons of juice from Plymouth Orchards, fermented (and left on the lees) for 2 years before tweaking what was a boring final product.

    • 2016-10-08: Pitched D47 yeast.  Can’t remember if I used sulfite/Campden tablets to knock back wild yeasts.  OG 1.050.
    • 2017-03-25: added cinnamon stick, now common practice for all of my ciders.  At low levels, enhances apple perception and does not stand out as cinnamon.
    • 2018-08-18: racked and added:
    • 2018-08-23: kegged.  I hadn’t stirred in the leaf hops and they had formed a thick layer on top, with the top half being dry.  So the practical impact of the dry-hopping will be less than 4 oz for 5 days.

    The cider itself was clean but dull before dry-hopping.  To test the idea of dry-hopping, I’d pulled a 1 liter sample and added the equivalent of 4 oz Mosiac per 5 gallons.  The result was fascinating, like a white wine with tropical fruit notes.

    I’ve become inconsistent with taking final gravities, especially if the batch is many months old or is being stabilized.  Here it’s both, and I never measured the FG.  Let’s assume it’s 1.000 which would be an ABV of 6.5%.
