Cookie mix

In the past two blogposts I’d described a knee injury. I’d neglected to mention in the same accident I also broke my foot. This means one injured knee, one broken foot. On opposite sides. And lots of time at home.

So, 2 months of recuperation has meant 2 months of baking. The latest being cookie mix. It wasn’t bad. I probably won’t make cookies from a mix again but found the process worth documenting.


  1. Chocolate chip cookie mix

  2. 1 stick of butter

  3. 1 egg


  1. Soften butter.

  2. Preheat oven to 375 degrees F.

  3. Dump mix in a large bowl. Add 1 egg + 1 stick of softened butter.

  4. Combine mix, egg, butter with a wooden spoon until there’s a fairly mealy but consistent substance that sort of resembles cookie dough.

  5. Form dough into small balls, about 1/2 inch in diameter. Place on a baking sheet.

  6. Bake for 10-15 minutes.

  7. Cookies!

Boiling water cake

My knee is mending slowly. I’m able to move enough to stumble through our apartment, shuffle between conference rooms at work, and take the stairs slowly to retrieve the Sunday paper. I spent all of yesterday at home reading about fish and listening to weekend public radio.

I also made a chocolate cake because a) it goes well with ice cream and b) adding the boiling water to the batter is one of the more satisfying actions one can take while baking – the batter goes from looking like brownies to dark chocolate silk.

Here’s my take on the recipe – it’s from the Hershey’s cocoa container:

Hershey’s perfectly chocolate chocolate cake


  • 2 cups sugar
  • 1-3/4 cups all-purpose flour
  • 3/4 cup cocoa
  • 1-1/2 teaspoons baking powder
  • 1-1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 eggs
  • 1 cup milk
  • 1/2 cup (1 stick) melted butter
  • 2 teaspoons vanilla extract
  • 1/2ish teaspoon almond extract
  • 1 cup boiling water


  1. Heat oven to 350°F. Grease two 9-inch round baking pans or 1 13x9x2 inch baking pan.

  2. Stir together sugar, flour, cocoa, baking powder, baking soda and salt in a large bowl.

  3. Add eggs, milk, butter, vanilla and almond extracts; beat on medium speed with a mixer for 2 minutes.

  4. Stir in boiling water (batter will be thin). Pour the batter into prepared pans.

  5. Bake 30 to 35 minutes (more like 40 min with the 13x9x2 pan) or until a knife inserted in center comes out clean. Cool for ~10 minutes.

  6. Skip the frosting and serve with ice cream of your choice.

Taking a knee

I fell on the sidewalk a week ago and landed on my kneecap, resulting in one of the most impressive knee lacerations I’ve ever seen. The accident happened in a public location, so folks got me connected to the ER and treatment ASAP. I’m now home recuperating. I can’t flex my knee and have crutches. I can rest, work remotely, commute (when I want to), and am in minimal pain. I’ve had to cancel travel, rearrange plans, and revisit my Netflix queue. I’ve also had incredible support from people who’ve helped me continue to get things done and a spouse who spent all day at the clinic with me.

My own thoughts want to discount the wound, but in reality it is severe and warrants time to heal – at least a couple weeks. So here I am writing this post as a reminder to slow down and recuperate when I need to, even if the cause doesn’t seem as bad in my own brain.

Rocky road

The San Francisco bay area is one of the best places to find ice cream, maybe 2nd to my home state of Wisconsin. We’re spoiled here. There’s all varieties of premium- or super-premium local brands, non-dairy alternatives, all the national brands, and a myriad of specialty ice cream shops (and long queues that go with them). Sometimes, though, I don’t want fancy ice cream. Sometimes I prefer cheap rocky road.

Let me explain. Cheap rocky road contains creamy not-too-strong-nor-sweet chocolate ice cream, the indication of nuts, subtle chocolate bits (not really chips), and perhaps if you’re lucky a mini marshmallow or two. I enjoy this combo immensely because it rewards the hunt for the marshmallow with the chance to eat twice as much ice cream. I like to eat this in a coffee mug. Sometimes even in a cake cone that’s about to crack because I’ve stuffed it full.

Regatta day

I rowed my first official regatta today – the Norm Petersen regatta. Our 6-person crew in the South End took a medal and everything. The course to the Golden Gate Bridge and back was smooth with a few roller waves abeam Marina Green. We launched fast to the start, sprinted hard against the other sweep boat over the 5+ mile course, and held our ground strongly to the finish. Less than a mile from the finish the other boat caught a faster current and won the race by 7 seconds. I also broke in a new oar with a couple blisters on my right hand (feathering the oar got sticky).

January break

I was able to take a break after leaving Mapbox and am starting a new role very soon. Here’s a look back at how I’ve spent January 2019:

  • Rearranged our storage closet
  • Lunched with friends at some of my favorite SF spots. Nopalito, Underdogs Too, The Grove, Barcha, The Snug, more
  • Wrote a few blogposts
  • Watched the fish at Cal Academy
  • Celebrated my dad’s birthday with my parents in Wisconsin
  • Swam and rowed in some wild winter water
  • Helped hire a new food pantry leader at church
  • Made so many dumplings
  • Baked Flour banana bread, cheesecake, quiche
  • Read A Year Off, China Rich Girlfriend, Devils Teeth, Shark Drunk
  • Got a massage
  • Visited SFMOMA – highlights are the Vija Celmins and The Sea Ranch exhibitions
  • Attended 4 yoga classes
  • Took one of the cats to the vet
  • Interviewed with some terrific teams – these conversations give me hope for an improving culture of communication in the tech industry
  • Saw Mary Poppins live at SF Symphony
  • Met some good dogs at a dog show

Launch and recovery

This past week I coached at a rowing clinic with one of my friends as part of a local school’s program. The students practiced erg technique in the morning, learned about the Bay’s history at the Maritime museum over lunch, and in the afternoon took to the water with us and the Sea Scouts. What a treat!

We’d had a successful launch out into our cove and the two rowers with me immediately saw their new technique come to life as we glided out on the water. We even got to practice some turns and stops as they switched seats. Returning was equally effective with a push from a northern wind and rolling swells.

Docking, however, was an adventure. Like any bow seat in a double scull boat, I had stern seat put oars up so I could guide us in and get extra oars out of the way. A couple feet from where I’d have backed in to the dock a swell pushed the boat over to the side of the dock and we headed straight for a barnacle-laden dock balance. I shifted to rowing backwards to get us out of the way but it was too late. We nudged the balance with an audible crunch, I uttered a couple profanities, then I furiously rowed backwards to get us out of there.

At this stage the smart thing to do would have been to row back out, take a deep breath, and try again. But I was determined to stick the landing and we were so close. I got us out of the channel, took 2 full strokes so we were parallel to the dock, and the current pushed us to the other side of the dock (near Hyde Street Pier)! We (literally) weren’t out of the water yet and I had to turn the boat around again. The students asked if I needed help. I said “no but this is a great lesson!”

After righting the boat with some furious backwards strokes and a couple river turns, and tossing the painter to the dock (the main rope at the boat’s bow), we were in position to come in and had a crew cheering us on. We pulled up, got out, and the boat and its rowers lived to see another day.


The Bay water temperature is dropping, most recently around 54 degrees Fahrenheit. The Bay activity is different this time of year, too. As more food sources shelter in the Bay from winter swells, so do seals and sea lions, eager for a nice meal of crab or perhaps sardines.

Yesterday brought not one but two pinniped encounters in the Aquatic Park cove (I’ll say pinniped to encompass all variations of seals, sea lions). One sea lion decided my friend was competing with them for food and chased her past the breakwater and along the Balclutha. She escaped with a scratch and some dents in her bright yellow fins. The other encounter happened minutes later when a gray harbor seal chased my friend all the way to shore – no nips or bites but a good scare. We’re not alone in the water.

Recently I’d ventured south to Año Nuevo state park. There, on the beach while looking at the surf lay a very sleepy elephant seal, so large it could be mistaken for a rock. I kept my distance (25 feet or more), but got close enough to see it exhale from whatever dream it was having. Elephant seals are less curious about humans than their seal and sea lion cousins – they’re barely aware of them but they can barrel over a human in seconds if food or a mate is nearby.

Luckily all the pinnipeds I mentioned looked fairly healthy and happy, but others aren’t so lucky.

Strategic meetings

I enjoyed a couple trainings recently from Gainsight and DSG about facilitating strategic meetings with customers. Here are a few take-aways in no particular order:

  • Set up goals at the beginning of the meeting with your customer, agree to them, and align next actions with these same goals.
  • If you’re meeting with an executive from your customer’s company, make sure your company’s counterpart can participate.
  • Keep goals for these meetings high-level and specific to your customer’s business. This is a great time to discuss increasing efficiencies, getting ahead of competition, and seeing more ROI for your projects together.
  • Draw charts and notes during the meeting to track goals, discuss industry trends, and align on next actions. Use a whiteboard, napkin, whatever you have handy.
  • Meet 1-2 times internally before the meeting to prep with attendees. Make sure your teammates know which topics they’re covering and what questions or comments could come up from the customer.
  • “QBR” (quarterly business review) is a bit of a misnomer. Hold strategic customer meetings as often as the relationship warrants. This could mean monthly, twice a year, etc.

Breakfast sandwiches

I’m often very hungry after morning swims and need to replenish whatever energy I’ve burned. Enter the breakfast sandwich. It’s delicious, it’s heavy, it’s portable. Burritos count. Here are a few of my favorites in/around San Francisco should you find yourself in a similar situation:

Special breakfast sandwich from Devil’s Teeth:

  • Why it’s good: scrambled eggs and cheese, avocado, spicy aioli, flake-y warm biscuit
  • Concessions you’ll make: waiting more than a few minutes (if it’s busy) as each one is made to order

Breakfast combo from Super Duper:

  • Why it’s good: no-frills egg/cheese/optional meat sandwich on a toasted English muffin, with coffee and a donut
  • Concessions you’ll make: this is Super Duper’s only breakfast option

Breakfast burrito from Uno Dos Tacos:

  • Why it’s good: the perfect size not-too-big breakfast burrito with eggs, cheese, potatoes, salsa, optional meat
  • Concessions you’ll make: longer lines as of late but they move fast
