If you're weird enough about the internet that you've ended up on Bluesky, you almost certainly would like Never Post It's one of the most consistently "worth listening to" podcasts I know of (and this episode specifically is such a breath of fresh air in comparison to the recent media cycle)

Ink & Switch's approach of being forward-looking while staying uncompromising on both the value of intention in what you make and the necessity of shaping the world to match your and your community'´s system of values is (in my opinion) the most essential message in software right now
A quote from Peter van Hardenberg, the lab director of Ink & Switch, from his talk "How to Research Tools for Thought":

"I would encourage everybody to think about how – as we're moving through this new world – that we are intentional about how we shape it. And I don't want to tell you whether you should or shouldn't adopt any particular technology, but I will tell you that the world will not wait for us – and that we need to figure out how we can engage with our values and our intentions, and how we can serve our communities to make sure that the people who are using these tools that we build and that other people build are able to do them in safe and trustworthy ways, but also in ways that are satisfying and joyful and let us have what we set out to do."

"Open source RSS readers have a UI that is at best lovingly brutalist and at worst too clunky for my use case" is a good chunk of the reason why Serial exists! If you're someone who's looking for a different option, give Serial a shot: github.com/megaflorasof...

Does anyone know what the state of music-based lexicons is? I've taken a peek at @rocksky.app and @teal.fm 's approaches, but I'm curious if there's been any push for a standardized concept of a "song" / "recording" / "album" or if there's just simply not enough ecosystem need for that yet

This is not production-ready (the code is slop), but I have a working shared document editor based on AT Proto's new private spaces alpha up! It's an experiment in how possible it is to combine something like @jakelazaroff.com 's AT ProtoCall but for WebRTC data channels, for private data + realtime

God bless whoever put up this pro-upzoning poster in Edgewater, please put up more
A flier taped to a streetlight pole that reads:

“I also have access to a printer,
And I say
Upzoning is cool and good and it is my friend

Let ‘em build some housing! What're you worried about, people with jobs and homes using the Red Line?

Atraid of density? then why did you move to the big city my good friend [emoji making a ‘this guy’s nuts!’ gesture]

‘But I wanna drive my car!’
The bus is better because you can read a book on the bus

Dear ‘Save Edgewater’: If I ever see you again claming that increasing supply increases prices I will spank your bottom and enroll you in an econ class at Loyola

Say YES to proposed Upzoning in Edgewater

This is a budget for a declaration of total war on the population. It's the building of an army of blackshirts and the creation of a massive system of concentration camps. A crystallization of everything lurking below the surface of the American project.
