How does this compare with existing access control solutions like https://aws.amazon.com/cognito/ or auth0 rbac?

I tried to get docker layer caching working within GHA for a second benchmark, but it seems like none of the approaches work particularly well for a "docker-compose build" - I'd happily amend the post with a second benchmark

> Why do you need to snapshot live processes? Often times there are long-living processes which rarely change but take a long time to warm up. The Bazel [1] agent for C++ projects, the buildkit [2] state for docker, or the running Postgr

Just a rebranding! (The technology's gotten better as well, of course - we didn't used to use firecracker at all) https://webapp.io/blog/layerci-has-rebranded-to-webapp-io/

Author here! I think there's always been a push/pull of "fat base images" versus "install everything every time" - It's obviously subjective, but I think it's more important to run the tests on every

Author here! The three big differences are: 1. Docker doesn't deal with running processes (like postgres or redis), only the filesystem state 2. Docker doesn't have enough isolation, so you'd probably need to run it within qe

When you say "8+ seconds", is that the startup time for the postgres instance?

The odds that you would exist to perceive yourself existing, however, are 100%.

Me and a friend have been working on this small framework that wraps esbuild ( https://esbuild.github.io/ ), it adds a few javascript tags like <Router> and <Head>, then pre-renders pages with headless chrome and

Since it's pub/sub, you just need one misbehaving client that LISTENs in a transaction to have problems, the other clients can still receive and process the NOTIFY event

I should've clarified, the database handles more than just the "regular" pub/sub, some of the tables have over a billion rows.

Ah, the database does a lot more than just pub/sub - especially since the high traffic pub/sub goes through redis. I guess my point was that we never regretted setting up postgres as the "default job queue" and it never

Such a server is 400$/mo, a backend developer that can confidently maintain kafka in production is significantly more expensive!

Didn't want to deal with ramifications of statement timeouts in a complex system, the failure mode mentioned (queue filling up) happened on the scale of 6 weeks, so it was very cheap operationally to set this timeout to some high value

Author here! A few updates since this was published two years ago: - The service mentioned (now called https://webapp.io ) eventually made it into YC (S20) and still uses postgres as its pub/sub implementation, doing hundre

I've talked to a bunch of startups that are using rrweb behind the scenes - onboarding, product feedback, etc all need some variant of this functionality.

Hey HN, Lots of people need help with optimizing "npm run build" time, so I built this analyzer - it looks at source lines of code (versus the bundled size for something like bundlephobia) so that you can tell what packages are ca
