   Project mention: Don't Build Multi-Agents | news.ycombinator.com | 2025-09-01

   I am in the USA! Although these days that exclamation point doesn't feel great...

   I'm using an old Android phone (Pixel 2 from 2017), a 5$ a month unlimited SMS plan from Tello, and https://github.com/capcom6/android-sms-gateway. For bonus points (I wanted to roll my own security, route messages from different numbers to prod and ppe instances of my backend, and dedup messages) I built a little service in Go that acts as an intermediary between my backend and android-sms-gateway. I deploy this service to my android device using ADB, android-sms-gateway talks to it, and it talks to my backend. I also rooted the android device so I could disable battery management for all apps (don't do this if you want to walk around with the phone of course). It works pretty well!

   I plan to open-source this eventually TM, but first I need to decouple my personal deployment infra from the bits useful to everyone else

   Project mention: Introduction to GrapheneOS | news.ycombinator.com | 2025-09-14

   Re: not using Google Play

   I'm not using GrapheneOS (I am unwilling to give Google money directly), but I did recently move to my second Android phone after having been a decade-plus iPhone user.

   When I got my first Android phone I decided to "sideload" all non-stock software on the phone. I never have setup a Google Play account. I kept all the APKs for the software I loaded over the three years I used the old phone.

   When I got the new phone I loaded all the software I use day-to-day and imported my SMS, contacts, and call logs using a nice FOSS app[0]. It felt remarkably like moving to a new PC does. It was nice.

   You definitely don't need Google Play to get a lot of functionality. I have run into a number of apps that I can't get to "sideload" (basically any xapk-packaged apps) but I don't need any of the badly enough to care.

   I am really sad Google is ending this moving forward. Jackasses.
