I believe their food options here are actually quite similar to local cafes. No sausage biscuits sadly!

What happens to Square / Block Android OSS projects post layoffs?

Let's start with some context

OSS at Square is mostly a happy accident. Jack hired Bob, who's job was attracking world class engineers, and he did that through talks & OSS.

Metro 0.11.0 is out now, along with a new proposal system called MEEPs!

It is the year 2026, people are still confused about compileSdk and targetSdk. (e.g. you can have targetSdk that is higher than compileSdk)

Maybe this will explain it a bit more.

Today is Bandcamp Friday - Bandcamp is waiving their fees and passing the funds directly to the artists - so I went shopping. Got the entire Spiritbox discography and a few As I Lay Dying and Parkway Drive albums. One step closer to cancelling my Spotify subscription!

The UK and the EU: best buds again? — The Europeans You’d be forgiven for forgetting that Europe is bigger than Davos this week, but we’ve got three great stories to remind you. First up: it’s been a good week for Berliners making Kartoffelsalat, Karto...

🚨 NEW EPISODE 🚨

Everyone’s watching Davos - so we’re talking about some of the other European news.
This week: potatoes in Berlin 🥔, a leaked “Made in Europe” proposal, and an interview with a sitting UK cabinet minister on the UK’s “reset” with the EU.

As great powers abandon rules and values for their own interests, middle powers like Canada have a choice: compete with each other for favour or act together with impact.

The Resonant Computing Manifesto Technology should bring out the best in humanity, not the worst—a manifesto for resonant computing built on five principles that reject hyper-scale extraction for human flourishing.

Sharing the Resonant Computing Manifesto I just signed: resonantcomputing.org, I agree with the vision it outlines. Check it out, and if it resonates with you - join me in signing it.

Screenshot of an article from Global News. The headline reads: Carney announces $2.5B for Ukraine in meeting with Zelenskyy.

Canada stands with Ukraine. Our new loan guarantees and financing will support a just and lasting peace — and help the Ukrainian people rebuild and recover.

I think it launches Siri by default? But maybe there's a setting to change that.

Next thing to try - carbonated coffee?

It makes no sense to me that the shutdown button for an iPhone is located under General Settings.

Jesse and Jake were my CN Tower. I only worked with them occasionally, but I always felt reassured just knowing they were around if I needed help. I'm mad our company lost both of them in the same week, and I'm afraid the entire Android OSS community will feel the ripple effect in the days to come.

Cash Android Moves to Metro The Cash Android team have completed the migration to Metro.

Cash Android has recently switched to Metro, a new, fast dependency injection framework built for K2. That was a fun project and we're really happy with the results! Sharing details on how we approached the migration to help teams adopt Metro: code.cash.app/cash-android...

I'm surprised how bad Gboard's predictions still are in 2025, especially in languages that are not English. This feels like an area where LLMs surely would shine, but apparently not? Or Google just doesn't care enough about Gboard?
