Just some kitties basking in some sunshine.

Krios is obsessed with towels. Put a towel down, he’ll lay there.

I have this take that I'm struggling to put into words, but I believe when possible, you should prefer maps to conditionals.

There was a talk by Sandi Metz years ago, I'll try and find it, but she says, "I'm condition averse, I want to pass messages to objects" and I think she's right.

I didn’t get to share this since my vacation, hasn’t been cold enough to wear it, but I picked up this really cool hoodie at the Museum of Anthropology.

It’s made by nativenorthwest.com

Just finished Recursion by Blake Crouch. This book was phenomenal.

It’s what Christopher Nolan wishes Tenet was.
The book cover of Recursion by Blake Crouch. It’s got an infinity symbol as the main image.

Then this evening I did another walk on the waterfront

More from MOA
I don’t know what you would call this, but it’s like a mosaic of bright colors made of figures of people and flowers A collection of ceramic owls A contemporary First Nations artwork piece an attribution

Then we went to the Museum of Anthropology. Incredible collection.

The whole time I was thinking, “Art is what we make when we have time. So few of us have time anymore.”

Last day in Vancouver photo dump. Started the day getting an amazing brunch in Chinatown.

Sausage and two eggs on top of maple ricotta pancakes. It was perfect.

Also went to the Capilano Suspension Bridge Park, that was a lot of fun.

I didn’t take pictures from the bridge, too busy keeping my balance, but here are pictures from around the park.
Entrance to the park, its logo surrounded. Y Jack o lanterns. A totem pole, roughly 25’ tall, it tells the story of a raven who gave us the stars and the moon A view from the cliff walk back to the suspension bridge. The valley floor is about 230’ below This tree who’s roots and trunk form a wildly acute angle hanging off the side of a cliff

Took the tram up Grouse Mountain today. Pictures can’t do it justice. Pretty way to view Vancouver.
A view from almost 4000’ looking down at the city of Vancouver and beyond.

Anyone else averse to unnecessary conditional checks?
// If you have a type like... type SomeObj = { items?: Item[] } // where items is optional, avoid doing this... const { items } = someObj if (items) { items.forEach(/* or map, filter, sort, whatever */) } // and prefer doing this... const { items = [] } = someObj items.forEach(/* or map, filter, sort, whatever */)

Do you got friends that love you enough to make you a custom bags set with your faces on it?
Two bags (cornhole) targets, one with my wife’s face and one with my beard on it.

I really love how the big Douglas firs get silhouetted at sunset.

They got the pavers in. I can use my front door again! Been almost a year 😅

Will there ever come a day I don't have to teach people this lesson? Enumerate, don't boolean-ate, people.
// If you ever find yourself setting a bunch of booleans at once // (and probably doing it in multiple event handlers) function handleImageLoad() { setImgError(null) setImgLoading(false) setImgLoaded(true) } // Consider using a string union to represent that state instead type ImageState = 'loading' | 'loaded' | 'failed' // Event handlers are a lot simpler function handleImageLoad() { setImgState('loaded') }

Something that just clicked for me, template string types in TypeScript make Cartesian products sooooo easy.
// Cartesian products without a utility type // In golf, there are really only 9 ball flights. They are the // Cartesian product of the starting line/direction type StartLine = 'straight' | 'pull' | 'push' // and the curve of the ball type Curve = 'draw' | 'straight' | 'fade' // template types make this soooo easy type Flight = `${StartLine}-${Curve}` // The result is: // straight-draw | straight-straight | straight-fade | // pull-draw | pull-straight | pull-fade | // push-draw | push-straight | push-fade

Haven’t had front steps since I tore down the dilapidate wooden deck last summer. So close to having this done.

All those years of math paid off. Finally had an occasion for using a quadratic equation in some code.

I'm building a little wedge training program in my golf stats app, and the scoring system is intended to reward good shots and severely punish really bad ones.
A graph showing the results of the equation -(1/37.5)x^2 + 10 The code implementing the quadratic formula ``` case 'SUBMIT_SHOT_RESULTS': { const score = state.shotResults.reduce((acc, result) => { const difference = Math.abs(result.distance - result.targetDistance) const percentage = (difference / result.targetDistance) * 100 const nextPoints = -(1 / 37.5) * Math.pow(percentage, 2) + 10 return acc + Math.round(nextPoints) }, 0) return { ...state, status: 'complete', score } } ```
