I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold. We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940. 2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.
Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.

Did you experience some bad performance while debugging your app with #dotnetmaui compared to #xamarinforms? Well there is an impacting change with MAUI...but you can revert it!
