Celery on AWS ECS: Complete Guide #python jangiacomelli.com/blog/celer…
Celery Organization retweeted
Introducing FrontierCode: a coding eval that raises the bar for difficulty & quality. Each task took 40+ hrs of work by leading open-source maintainers.
Models write sloppy code that works but isn’t maintainable. Our eval is first to measure: would you actually merge this code?

Since I started contributing to Celery, improving the QA was one of my highest priorities, leading to the creation of pytest-celery v1.0.0 to support enterprise-grade QA requirements.
After endless nights of fine-tuning, bug fixing, and ensuring that we're g2g, I had to face the hard truth of our CI limitations. What my laptop did in 10m, took our CI about an hour, and that was just a simple PR..
Blacksmith has completely changed the game by unleashing the full potential of our new QA infrastructure, virtually unlimited concurrent PRs, NO DOWNSIDES, and I still can't believe it was 1-click away.
Thank you for sharing our story @useblacksmith.
Appreciation > 9000 🔥
.@CeleryOrg → Blacksmith: 4x faster GitHub Actions, 4x higher contribution rate.
“After switching to Blacksmith, everything else just feels primitive.” @smilingnosrati, Tech Lead at @CeleryOrg.
Here’s the story of how Celery, the first open source project we sponsored, stopped waiting 4-hours on PRs…
Fun fact: When our CI performance quadrupled, our contribution rate did too. Huge thanks to @useblacksmith for powering our CI!
The impact was real.
We’re giving away up to $250,000 a year in compute and storage credits to OSS projects.
We’re on a mission to rescue open source from @github's slow CI, one project at a time. Our new OSS program already powers CI for Celery, @ladybirdbrowser, @zen_browser, and Limbo.
Say no to slow CI and apply now on our pricing page.

One of my personal objectives for the @CeleryOrg this year is improving customer support at scale. I've explored numerous AI solutions, but none have had such a massive impact as this one.
My CeleryGPT dream is slowly taking shape, step by step..
What a time to be alive 💫
One of our maintainers' biggest challenges, offering high-quality support within a reasonable SLA, is now much easier to address. We thank the team at @cognition_labs for making DeepWiki (powered by Devin AI) available for everyone to use with Celery!
