At Estuary, we have an in-house Rust crate [1] for building scale-out durable actors / FSMs in Postgres. It powers all async activity in our control plane -- slews of fine-grain sc…

The right metaphor isn't painting, though, it's molding clay. That first pass is slop, but it's raw clay that the agent is very good at molding given a modicum of direction and "no…

I ask Claude or codex to review staged work regularly, as part of my workflow. This is often after I’ve reviewed myself, so I’m asking it to catch issues I missed. It will _always_…

I think there's a Danger Zone when planning is light-weight and iterative, and code is cheap, but reviewing code is expensive: it leads to a kind of local hill-climbing. Suppose yo…

Maintaining a high-quality requirements / specification document for large features prior to implementation, and then referencing it in "plan mode" prompts, feels like consensus be…

As someone with workloads that can benefit from these techniques, but limited resources to put them into practice, my working thesis has been: * Use a multi-threaded tokio runtime …

It still doesn't make sense. Cursor undoubtedly has smart engineers who could implement the Anthropic text editing tool interface in their IDE. Why not just do that for one of your…

> You can't do that for LLM output. That's true if you're just evaluating the final answer. However, wouldn't you evaluate the context -- including internal tokens -- built by the …

But that’s not good. You don’t want Bob to be the gate keeper for why a process is the way it is. In my experience working with agents helps eliminate that crap, because you have t…

Hi, I’m a cofounder / CTO of estuary.dev. Our whole mission is democratizing and enabling use of data within orgs. Open to a conversation about your work here? Reach me at johnny a…

I would recommend the `anyhow` crate and use of anyhow::Context to annotate errors on the return path within applications, like: falliable_func().context("failed to frob the peanut…

> There's so many moving parts here. Yep. At the scope of a single table, append-only history is nice but you're often after a clone of your source table within Iceberg, materializ…

The market is gobsmackingly huge, it's just the go-to-market entry points which are narrow. In my opinion, the key is to find a value prop and positioning which lets prospects try …

> To me the best solution seem like combining storing writes on EBS (or even NVMe) initially to minimize the time until writes can be acknowledged, and creating a chunk on S3 stand…

Roughly ten years ago, I started Gazette [0]. Gazette is in an architectural middle-ground between Kafka and WarpStream (and S2). It offers unbounded byte-oriented log streams whic…

One labeling is "organised crime". Another is: civil disobedience with a profit motive.

Or, it can be self-evident to all that today's work can deliver more benefit if focused elsewhere, instead of root-causing fickle alert flakes. Customers buy products and services,…

The first place I'd look is using binary search over a sorted `Vec `. The `superslice` crate is handy for this, or just using the built-in binary search methods. The improved cache…

Companies have internal processes and typically can’t say “here’s an extra 5k for saving our butts!” unless there’s an existing program and money set aside for such spot bonuses. I…

PostgreSQL. The WAL is an event log, and when you squint at its internal architecture, you’ll see plenty of overlap with distributed event sourcing.
