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.

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

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!

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.

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.

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.

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?

In a highly modularized codebase, typing full Gradle task names can be tedious. Gradle supports task name abbreviation: just type the shortest unique prefix. If ambiguous, Gradle suggests candidates.

⚠️ Use locally for speed, but keep codebase references explicit for readability!

Things that make me grumpy:

- Mobile operating systems that don't batch notifications and have no problem buzzing me five times within five seconds.

I feel like I'm slowly starting to develop intuition for things I want to write myself vs things I don't, and using AI for the latter. E.g. generating test data, or scaffolding for a UI component. So I wouldn't say it's completely useless for me, just not as useful as it's advertised to be.
