With the announcement (and merge) of ActiveJob::Continuation, it is a perfect time to announce that my pilot for AcidicJob Pro is finally ready for the first 5 companies/agencies that reach out. If you need ActiveJob::Continuation++ with extra tooling and observabikity, HMU!

Telesink runs on Rails. For jobs: Solid Queue + Mission Control - great stack.
But one thing was missing: real-time visibility.
So I built it.

Heads up when testing ActiveJob:
`perform_enqueued_jobs` creates odd situations when testing retries, because it performs the jobs immediately on the call to `enqueue`.
`flush_enqueued_jobs until enqueued_jobs.empty?` creates much more realistic scenarios, as it enqueues then performs.

Enqueuing a lot a jobs really fast
Enqueuing via ActiveJob::Base#perform_later triggers callbacks and generates one round-trip for each job. Bulk enqueuing skips callbacks and enqueues all jobs in one step.

Here's what @claudiob had to say after using ActiveJob::Performs:
I’ve been using active_job-performs for the last month and I love it love it love it!!
Your thought process behind it is so thorough. I have a bunch of jobs now attached to models and my app/jobs folder… is empty!!
This saves me a lot of mental hoops, I don’t have to switch between files anymore, everything is self-contained. Thank you!!!
From @andycroll in a writeup about launching UsingRails:
I’ve also adopted a couple of gems—with exceptional Rails-level taste and author pedigree—that I hadn’t used in anger before, including active_job-performs from Kasper […]. Would recommend both.
And @nshki after trying it:
Spent some time playing with @kaspth's ActiveRecord::AssociatedObject and ActiveJob::Performs and wow! The conventions these gems put in place help simplify a codebase drastically. I particularly love ActiveJob::Performs—it helped me refactor out all ApplicationJob classes I had and keep important context in the right domain model.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ps3ygxhsn4khcrxeutdosdqk/bafkreihlrddut67f3e5fyv7vjicklrg4suhtasfhahstluqe2efom4gcru)

curious if you've benchmarked this with Sidekiq also running through ActiveJob. IIRC ActiveJob does slow things down some but I'm curious how much.

Gotta give mad props to @seuros for shaking up the Rails error tracking game.
He’s building Lapsoss - a vendor-agnostic library for error tracking. Think ActiveJob, but for errors.
Switching from Sentry to Honeybadger? With Lapsoss, just change the adapter, the API stays the same.

Currently in ActiveJob, `wait` in `retry_on` accepts a proc, but it is only handed the execution count. I think access to the error can also be useful when calculating the next wait time. If you agree, give it a like! github.com/rails/rails/...

One thing I'll say, Rails has a ton of good stuff in it. I think ActiveRecord is really well done, ActionController is pretty good, and ActiveJob is OK.
I think the front-end is an insanely complicated, creaky mess... with the exception of Turbo.
Oh and Rails CLI drives me crazy.
