Cool Reader mentions (2)

  • Recommended E-reader? [more in comments]
    An Android tablet and the CoolReader app. For me, it's simply the best eReader experience available. It's incredibly customisable. The only downside is it doesn't support PDF or AZW3, both of which can be reformatted to your preferred file type with Calibre anyway. Source: over 3 years ago

Fly.io mentions (482)

  • Best alternatives to Heroku in 2026
    Fly.io opens up two things Heroku keeps at arm's length: real multi-region deployment and full control over the runtime. Heroku's Common Runtime offers two regions (US and EU), and Private Spaces gets you one region at a time from a wider list. Fly runs Firecracker microVMs across eighteen regions on six continents, and replicas can be pinned to specific cities. If your Heroku app has global users and you've been... - Source: dev.to / 5 days ago
  • Building an autonomous Slack agent with OpenCode
    The gateway is the web service that receives requests. I host it on Fly. It accepts Slack events, automation API calls, trigger requests, Composio webhooks, Inngest calls, and runtime calls. - Source: dev.to / about 1 month ago
  • It Worked on My Machine (Literally)
    The tunnel was never meant to be permanent (it runs off my laptop, and the URL changes every time it restarts), so the next step was deploying somewhere real. I built the Docker image for Fly.io, set my username, and shipped it. - Source: dev.to / about 1 month ago
  • I Built a Zero-Knowledge Encrypted Habit Tracker with Elixir & Phoenix LiveView
    Three independent encryption layers at rest: client-side E2E, Cloak AES-256-GCM in Postgres, and LUKS disk encryption on Fly.io. - Source: dev.to / 3 months ago
  • One honojs file for entire web scraping API
    I'll also provide github repository in the end, which you can use easily to launch your own scraping APIs on vercel, Cloudflare, netlify or, fly.io or even on a Docker container. - Source: dev.to / 3 months ago
