rdlu

From the "I wanted it to exist so I made it" department, I present: rdlu. It's a Sokoban clone. But you can create and share levels on Secure Scuttlebutt. The levels also contain full cellular automata-style rules for the game (@$_ => _@*), so you can modify and add to those, too. Finally, I made it in Tilde Friends, so you can muck with the source as much as you like and make it into your own thing entirely.

It publishes and consumes rdlu-level messages with a source field containing a description of the level and rules as text.

If you just want to see it in action, it lives here, no Tilde Friends account required to play: https://www.tildefriends.net/~cory/rdlu/.

Ideas for social networks

I'd love to see people playing with SSB like this in Tilde Friends or otherwise.

New Windows File Explorer feature coming soon:

New! Address bar now supports ~, making it quicker to navigate directly to your user profile folder and subfolders (for example, ~\AppData).

ssb-validation-dataset question

I'm long overdue testing against the ssb-validation-dataset, so I'm embarrassed to ask, but what's the deal with hmacKey? I've gotten along this far without validating against anything like this in practice, I think. What am I missing?

Garmin Revamps and Opens Up Connect Developer API Program

Ooh, this is the least bad internet news I've seen this week. I dabbled with using GPS data in Tilde Friends years ago. My application to use the Garmin API at the time was rejected, because I didn't check all the enterprise boxes thoroughly enough. I ended up using Strava's API for a bit, but they've progressively restricted that, too.

Not sure I'll have the time to play with it anytime soon, but I would love to build something sort of community-oriented around sharing activity data someday.

It always struck me that Strava is the most widespread thing I'm aware of that has the same problem with time as Secure Scuttlebutt, in that people record activities on their watches and upload them hours, days, or weeks later when they are next able to recharge and get a reliable internet connection. It's not unusual to post a batch of activities from a week ago when traveling, and we deal with the feed being oddly ordered.
