A fresh PWA to log / improve your coffee brewing process. We use it to see what we are all drinking, find new coffees, explore new cafes, and understand what we like / don’t like.

It’s primarily used by our group of friends, so if you see a rough edge somewhere please reach out!

>> critics argue that it reduces the supply of rental apartments and creates housing shortages

I don’t follow the logic. It doesn’t destroy the property or take it out of supply, it just means someone might not purchase it specifically to rent it out. Which in turn means less demand buying houses overall, which means more opportunities for people to buy (if they want?)

Agree - I’ve been using a set of Eve (from memory) power plugs that are thread enabled - my understanding is it doesn’t connect directly to the internet (ie you don’t connect it to your wifi) but you connect to a border hub (ie an Apple TV, or maybe now an iPhone 15.)

So I guess if you trust apple, you can sorta trust these devices as their access to the outside world would be through an apple device.

I just got back from the Banff Film Festival, where I saw Fire of Love[1]. It’s the story of French scientists Maurice and Katia Krafft, who become fully devoted to each other and the study of Volcanos for the rest of their lives.

Created using hours of their archival footage, it’s a story driven by a singular shared passion, amazingly found by two people born only 20km apart.

michaelje | 3 years ago | on: Analysis of Apple Watch running data

I’ve just completed a 6 month self comparison of the Whoop v4 and Watch S6 for cycling. I found for long endurance efforts they were surprisingly accurate to each other - but during intervals of intense exertion (eg a KOM/hill climb) often the Whoop would read my HR as ~40-60BPM lower while the watch would reflect an expected reading (160-180bpm). Sometimes after 1-2 mins the whoop would “catch up” but it would leave a giant drop in HR graphing for that interval.

This also lowered the avg HR for the workout on the whoop, as you noted. Happy to share an example comparison graph if you’re interested, just reach out.

For what it’s worth, I ended up cancelling the Whoop this month after trying twice to engage with their data team.
