I think it’s still a valid question if you frame it along the lines of “something useful at protests, but also in everyday peaceful life”.

Meshtastic LoRa is worth looking into if you’re going to protests with friends/family/cohorts. You can get a waterproof, GPS enabled, credit-card sized module with multi-day battery life and no flashing required for $35 (T1000-E). That’s specifically because it can also be used when hiking, going to festivals, or just for fun.

I was just at a Mardi Gras parade and text messages couldn’t go through due to network congestion from too many people. With a couple of meshtastic devices our phones could still text each other and see our GPS positions on a map. All with encryption enabled.

Love the idea so much that I tried it. Turns out a url for a babel page is around 2,000 bytes :-(

Same old story of a community-driven site resorting to ads for revenue. After feedback they started a subscription-based version called totalFark that didn’t have ads. Then they introduced ads on totalFark as well, but didn’t vet their advertisers. So some of the banner ads were running malicious code on users browsers.

Love the idea! Kinda like fark.com before they got all shitty.
