Just watched a video on EV performance on a Saskatoon night (where I went to university) at -35C. Used a lot of battery but the car performed great. And you know, I miss that adventure of waking up to -35C and heading to school and the sound of the snow crunching under your feet.

My fave tip for dev #swiftlang -> Linux, check how your Swift package compiles while on your mac w/ container:
container run -it -c 4 -m 8g \
-v "$(pwd):/src" -w src/ \
swift:6.2 sh -c "swift build"
(runs a Swift 6.2 image, gives it 4CPU and 8GB, mounts your PWD as "src", and builds)
container run -it -c 4 -m 8g \
-v "$(pwd):/src" -w src/ \
swift:6.2 sh -c "swift build"
(runs a Swift 6.2 image, gives it 4CPU and 8GB, mounts your PWD as "src", and builds)

I spent many years in the Eclipse community and was so privileged to be immersed in their passion for building great things and lasting friendships. The last few weeks attending Swift community meetups, I'm seeing that passion again. I feel so at home!

Swift - Java interop I think it’s pretty critical to embed Swift as a server side language. If you can begin a transition incrementally, it’s always easier to move over.
Super cool to see this work, and congrats to Mads!

Bridging the Swift and Java worlds opens the door to a richer set of server-side use cases for Swift. In our latest GSoC spotlight, Mads Odgaard describes his work to expand access to Swift/Java interop. #Java #GSOC www.swift.org/blog/gsoc-20...

When busy at work late into the evening making SwiftPM the best it can be, great to throw up Star Wars A New Hope to remind me what brought me to this game. Can't wait to focus more on Swift Embedded in SwiftPM to get it onto robots like this 😀 🤖 .

This is Winston Churchill visiting Washington DC to request assistance in the war against Germany. Notice he is wearing a "zip suit" and not a traditional suit. This was to honor the British troops--the same reason Zelensky dresses the way he does.
