Download Your acm-statistics (OJHunt Heavy) History
Recover your competitive programming history from the old site
What happened to the old site? acm-statistics was my college side project — a great excuse to throw every exciting
new technology into one codebase: .NET Core, Vue.js + Nuxt.js, microservices, a multi-image
Docker build system, docker-compose… The kind of over-engineering only a student with too
much enthusiasm and too little maintenance budget can produce.
As years passed, .NET upgrades arrived annually and JS frameworks hit major breaking changes
every few months. Even with Renovate automating dependency PRs, keeping everything working
demanded constant manual intervention. Then in October 2025 the VPS provider (CloudCone) was
compromised, and all data after 2025-10-22 was lost in the incident.
That was the final push to start over. OJHunt Lite was rewritten from scratch with the
opposite philosophy: as few dependencies as possible, no stored user data — you hold your own
history in a PDF. One server incident can no longer erase your records.
What you'll get: A PDF containing your daily solve-count history up to
2025-10-22, in the same format as OJHunt Lite reports. You can upload it on the
home page to restore your crawler list, or
merge it with a more recent OJHunt Lite report to combine histories.
Store the PDF on your own device — don't rely on browser storage,
which can be cleared at any time.
