Pricing Waterfall in Google Sheets
Its easy to use! I’m not certain who came up with the waterfall visualization (maybe BCG?), a variation on a standard bar chart, but they are super common in pricing analysis. They are an improvement on other bar charts because they show debits sequentially and then allow the user to see intermediate price points which…

NZ Wool Notes
I was on my way home from New Zealand today and I got diverted into the super long customs line because I had to declare the large amount of alpaca yarn I bought. Between the various agents I spoke to YARN somehow got lost in translation from English to English and as my bag was…

Normalizing Metrics: Percentages vs Percentiles
I was traveling the past few weeks and thought of yet another example of how intuitive it is to use the metric system. Its remarkable that we continue to resist it here in the US when it is whole-heartedly embraced throughout most of the rest of the world. It seems absolutely arbitrary that water freezes…

Donations aren’t free
Goodwill Finds business model musings Last year I spoke to a guy who was looking for pricing support for an online version of Goodwill called Goodwill Finds. I called my sister all excited to talk to her about Thrifting and get her perspective as a Seattlite on what opportunities might exist. The business model is…

My property taxes are higher than my neighbors Last year my property taxes went up 34.7% I’m paying ~$1700 more annually than the two neighboring properties which are almost identical, also 2400 sq ft up/down duplexes with detached 2 car garages. Price variation on this level is not supposed to exist within the same county,…

Unit tests are critical to writing good software
Tool to make this easier? CodiumAI I continually curse whoever designed the backup camera on our Ford Edge that they didn’t plan for a bike rack. Whenever you have the rack mounted the car aggressively warns you about the nearby object it thinks you’re going to hit. In pricing software implementations I’ve very rarely seen…

Is anyone really self-made?
recently bought a replica of this statue on Etsy. The name of the piece is “Self-made man” and it’s fairly new from a sculpture in Mexicohttps://lnkd.in/gCMjSxwG There is a tradition of people creating themselves from stone, but I like the idea of the person within the larger body for our era of excessive consumption, life…

PSA: You don’t have to honor bids from 3 years ago
I was pleasantly surprised to have my chimney rebuilt for the price my mason quoted in 2020. When we went to Argentina in 2010 my dad told me one of his economist jokes about hyper inflation:Q: Why do people ride busses instead of taxi’s in Argentina?A: Because on the bus you pay when you get…

Tolls: Value based pricing example
$7 is less than minimum wage for 1 hour of work in both the US and CN. Gas costs at least $4/gallon and given the extra distance you’d likely use 2 gallons. Detour minimum cost $15, toll $7. Google maps probably shouldn’t even show the no tolls route for this trip because the toll fee…
