No description of Rollbar yet.
Daily Coding publishes one programming challenge every day. Everyone gets the same challenge, and it stays up for 24 hours, the idea is borrowed from Advent of Code, but it runs all year instead of twelve days in December. You write your solution in the browser and run it against the test cases...

As answered by people managing Rollbar and DailyCoding.dev.
DailyCoding.dev's answer:
One challenge per day, and it is the same challenge for everyone. There is no catalogue to browse and nothing to pick, that decision is exactly what makes most people quit after a week. Once you submit, every other solution to the same challenge becomes readable, across all 11 languages.
DailyCoding.dev's answer:
Because it takes choice away instead of adding more. LeetCode and Codewars offer thousands of problems; Daily Coding offers the one that is live today. It is free with no paid tier, today's challenge works without an account, and the whole thing is open source under MIT, including the sandbox that runs the code.
DailyCoding.dev's answer:
Developers who want a small daily habit rather than interview grinding: people who enjoy Advent of Code and miss it in January, students and apprentices practising algorithms, and experienced developers warming up in a language they are currently learning.
DailyCoding.dev's answer:
I do Advent of Code every December and try to keep the habit going on LeetCode every January. It never lasted more than a week, too many problems, no reason to do this one today. So I built what I actually wanted: one challenge, the same for everybody, all year round. Seven months of evenings and about 470 commits later, it runs in 11 languages.
DailyCoding.dev's answer:
Next.js 16 and TypeScript with the Monaco editor, deployed on Vercel. Submissions are executed on a self-hosted Piston instance on a Hetzner server, with typed test harnesses generated per language. Prisma for data access, Postgres DB
