I should do a write-up! Maybe you'll see it posted here soon. We could basically find nothing online...

By experience, getting Firecracker to run well on M-series macs is quite the undertaking. I'm not at all surprised Encore decided to take this path considering their customer base!

At Lovable we decided to spend ~1 engineering month getting our sandbox infrastructure to be 100% runnable on Mac and on Linux with predictable builds using Bazel etc.

But we actively decided to take a different route than Encore and run nested virtualization, which on macOS means vfkit -> QEMU -> Kind + Firecracker vm(s). It's been invaluable to get the same development and testing tools on both platforms tbh.

This is exactly my experience at Lovable. For some parts of the organization, LLMs are incredibly powerful and a productivity multiplier. For the team I am in, Infra, it's many times distraction and a negative multiplier.

I can't say how many times the LLM-proposed solution to a jittery behavior is adding retries. At this point we have to be even more careful with controlling the implementation of things in the hot path.

I have to say though, giving Amp/Claude Code the Grafana MCP + read-only kubectl has saved me days worth of debugging. So there's definitely trade-offs!

I made this with Lovable as well, it's interesting how it's a bit more extreme in terms of where we are in 2035.

Neon does a variant of this. The WAL goes through a Paxos consensus directly on NVMe, which then is transformed to page files and stored in Object Storage

We're happy to announce an early version of https://github.com/molnett/neon-operator, a Kubernetes operator that allows you to self-host Neon on your own infrastructure. This is the culmination of our efforts to understand the internal details of Neon, and we're excited to share our findings with the community!

New comment by bittermandel in "Happy 20th Birthday, Django"

bittermandel — Mon, 14 Jul 2025 14:59:40 +0000

Django was the whole start of my career and I still thank it for many of my opportunities. I started in 2012 to work with Django at Billogram, then founded a Django consultancy which lead me to work at King 3 years later.

Who knows where I would be today if not for Django!

New comment by bittermandel in "Ask HN: What Are You Working On? (June 2025)"

bittermandel — Mon, 30 Jun 2025 08:52:18 +0000

We're working on a Container Registry for https://molnett.com. We don't really want to use Harbour as we want to manage our own AuthN/AuthZ and are fully multi-tenant, so we decided to build our own on top of Distribution.

Going from Manifest to OCI is a bit tricky and performance for calculating total storage based on metadata is hard to get right. But the result is that we own our full registry implementation and can take it any direction we want. Quite happy with that!

New comment by bittermandel in "The Ingredients of a Productive Monorepo"

I don't think you are wrong at all. As we are all founders with an OK salary and this is our area of expertise, so we're able to take advantage of our previous experiences and reap the benefits. We're probably uniquely positioned here.

I had massive issues at my previous employer with Bazel. They did not try to make Bazel work for non-SREs, which as you can imagine didn't work very well. So it's definitely not a silver bullet!

We should probably write a blog post about our setup!
