  • 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 / 1 day 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 / 29 days 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

  • keep making extremely dumb mistakes?
    Some companies use things like CoderPad or Google Docs (yes, Google really used to use Google Docs). Those don't let you run the code either so they're more like whiteboards. Source: over 3 years ago
  • Coding Test for Embedded Engineering Internship - not a fan of high level coding
    I am a CS major with a computer engineering minor. I want to prepare myself to apply for an Embedded Engineering Internship. The interview process includes a coding task on coderpad.io, I have no clue what to expect - what kind of questions will be asked for an embedded internship? I say this because coding embedded systems is rather different from "regular" coding in practice. High level v low level. Source: over 3 years ago

  • Is this a system design interview?
    I am prepping for a final round interview for a frontend position at a medium size company. The recruiter gave me some information about one of the coding rounds and I am not entirely sure what to expect.

I will be using https://excalidraw.com/ in addition to... Source: over 3 years ago
  • Live code screening practice?
    The specific target interview format I have in mind is via a shared, live editor (e.g. https://coderpad.io/) and a video link, lasting ~1hr. The practice format might be more like 45min for the interview followed by 15 - 30min for feedback and discussion. Doing two of those back to back so both of us get our chance in the hot seat could be exhausting, so this might be two separate sessions. Source: over 3 years ago
