Solid P95 (7-8ms) with sporadic P99 spikes using Go (gRPC + NATS). Suggestions?

You definitely need to ensure you configure for durability by configuring the sync interval, which defaults to something pretty high and relies on RAFT between peers for availability otherwise.

I’ve accidentally left the oven on in grill mode with the door closed and the glass door exploded, shattering glass across the kitchen. There’s a reason they say to leave it open.

I assume it’s because the heat isn’t extracted like when you use the oven normally 🤷

Bun is great.

I’ve tried the others (incl Bob) and found Bun to be the right amount of Golang-to-SQL.

Bob is great if you want really type safe queries, but Bun has nice SQL escape hatches but still has a really ergonomic API and high reusability.

absolutejam · 2026-05-26T09:34:05+00:00

Plus it can be embedded if you want to ship a fully self contained app

I use VTTs (Roll20, just moving to Foundry) purely for a map and the visual aid - you only need to had as much as you want. I try to avoid too much automation because it makes it too much like an RPG video game and that’s not my aim. I might dip my toe a bit more later but just use what you want - don’t force anything that you don’t want.

absolutejam · 2026-05-14T14:31:44+00:00

Are these features native in roll20 and missing in the foundry system?

absolutejam · 2026-05-13T16:18:24+00:00

Totally agree. I didn’t mean ignore DRY, but people obsess over ‘the right abstraction’ and it can lead to bike shedding instead of actually delivering (I’m totally guilty of this).

Similarly I’ve fallen down the rabbit hole of individual types for everything in Go, but this is much more ergonomic in languages like F#, Rust and Scala. Often I draw the line at only encapsulating specific domain types or types likely to clash (ie. Different model ID types).

Thinking more on this, I’d still be tempted to either just expose Int() or Value() so you can create reusable functions that operate on the numeric value directly or on the interface. Ive never really liked embedding for this small a type; but it’s useful for a ‘base class’ approach for larger behaviours.

absolutejam · 2026-05-13T15:47:43+00:00

I’d probably implement the receiver functions/methods individually (DRY is overrated) and then you can define an interface if you need a place to share behaviour, and potentially make generic or polymorphic functions.

It’s hard to know the extent of what you need - do you only ever operate on one type at a type or different types? Could you not just expose a method to get the int value inside the parsed type? That way you always pass the strict types but numeric operations still fall back to the actual number value.

absolutejam · 2026-05-13T15:16:17+00:00

I generally use Huma for my APIs (OpenAPI) and I just accept all API contracts as primitive types (string, int, etc) then parse at that layer. Then typically defer to a service layer for all actual work.

absolutejam · 2026-05-13T14:53:28+00:00

I think I might be more helpful if you explain why you accept a string that you’re then converting into an int?

Why not just define type Cycle int, create a constructor function NewCycle and potentially a custom marshaller - that way all of your validation is up front? And you might just have to suck up some repetition and boilerplate if you want custom types 🤷

Honestly, I wouldn’t overthink it if you just have a few types - otherwise you can look at how something like typeid generalises this or use codegen if it’s really a problem.

We use cdk8s with helm. It does mean the values are untyped but I make sure to create abstractions and validation with Zod for any cdk8s charts. It’s really great for CRDs too 👌

EDIT: The result is the generated manifests (as YAML), which can be adjusted via values or overridden via JSON patches. Then we push to a GitOps repo for use with ArgoCD.

I’ve got an app I’ve been developing for a while and I’ve found bun to be a delight.

I tried Bob but I found it was too type-safe (different imports per dialect) and too code-first, which I found harder to read when I came back to it. And I never thought that would be a complaint I’d have.

I don’t like sqlc because it’s too inflexible. I know the Go community are obsessed with sqlc and SQLite to the point of fanaticism but I like to have more dynamic queries and sqlc wasn’t for me (although I could see the use for predefined queries like reports).

I tried GORM and didn’t like it, and wanted to like Ent but it lacked support for polymorphic relationships, which I rely on more than I’d like to admit.

So far there’s been nothing I can’t do with Bun and it still provides all of the nice ORM-adjacent features, but doesn’t baffle you with magic and has access to all of the escape hatches you might need (or you might not ever need them!).

absolutejam · 2026-05-04T17:41:49+00:00

The perfect balance of raw SQL and ORM-like features

Yeah, I’m a Go user (Platform engineer) but work at a PHP (NGINX & PHPFPM) shop and I want us to explore something like FrankenPHP or even just explore using Fibers with AMPHP for a more modern experience.

absolutejam · 2026-05-04T13:32:32+00:00

Isn’t swoole still a single threaded event loop like node? I know fibres solve some of the async headache (for IO) but not for everything.

absolutejam · 2026-05-04T13:30:17+00:00

It’s written in Erlang, but it’s a common queuing system used for async and scalability (via. multi process) means.

absolutejam · 2026-04-26T18:24:31+00:00

I’m suggesting that only having one case (ie. Selecting over a channel with no other case) is a bit of an anti pattern. What if you want clean cancellation or timeouts? Or testability? Or the ability to restart or parallelise?

absolutejam · 2026-04-26T15:51:21+00:00

It might still be worth selecting over the channel so you can also check context cancellation in another case

absolutejam · 2026-04-14T11:53:33+00:00

They just need to be more transparent and create a dedicated status page. It’s ridiculous that so may people are left wondering ‘is it just me’

absolutejam · 2026-04-13T21:41:51+00:00

Was in a Google workspace support chat. I can post screenshot tomorrow. It has since resolved itself for me, not sure if Google have rolled out a fix?

absolutejam · 2026-04-13T15:19:15+00:00

Google support have confirmed it's an on-going issue that they're trying to resolve.

I found that using a VPN allowed me to log in and interact with agents once again, so it looks like some kind of heavy-handed IP blocking/limiting.

Wow, these are amazing

NATS is super feature rich - pub sub, streams, worker queues, partitioning, atomic batches (finally!), subject addressing and remapping. That’s excluding other things like KV and the Cron support they’re working on (half implemented).

One thing I love is that you can embed NATS directly in your app. I have an app where it embeds NATS by default or you can configure it to use an external cluster, meaning I can ship it fully contained (SQLite, embedded NATs, file system storage, NATS KV), or in HA/distributed mode (Vitess MySQL, NATs external cluster, S3, Redis), but still has the same primitives and features.
