Proud to announce that I effectively executed a rapid-response squirrel displacement strategy to mitigate potential yard intrusions.

Humbled by the unwavering support of my family and local stakeholders.

This experience reinforced the importance of vigilance, ownership, and continuous improvement.

Looking forward to scaling this impact in future engagements.

Calling transphobia a 'gateway drug' to the far right undersells it. It's pure accelerant. Grimly fascinating to guess what crankery becomes any famous transphobe's secondary obsession, cos they all have one: 15 minute cities are fascism! Grok noncing is cool! ICE are good! We should kill all dogs!

Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

Fantastic effort led by Jodie, Amber & Sophie. A few key takeaways: - Robustness of process. From v1, moderate genes -> definitive, (many)limited genes -> disputed - HCM becoming more complex - AR, semi-dominant, mito - HCM not just a sarcomere gene disease anymore, guidelines need to catch up

This.
A quote from the writer AR Moxon from 2017. He wrote:

"Historians have a word for Germans who joined the Nazi party, not because they hated Jews, but out of a hope for restored patriotism, or a sense of economic anxiety, or a hope to preserve their religious values, or dislike of their opponents, or raw political opportunism, or convenience, or ignorance, or greed. That word is "Nazi." Nobody cares about their motives anymore. They joined what they joined. They lent their support and their moral approval. And, in so doing, they bound themselves to everything that came after.
Who cares any more what particular knot they used in the binding?"
