Used up all my API calls for GPT 5.5 on @cursor_ai sub and now using composer 2.5, and I am still working away fine. 😅🚀

@testcontainers woops meant to reply with a URL, but started making banana bread 😂🍞 https://t.co/Hpq1S4ck5J

[Mark Wolfe 🐺 @wolfeidau]

Was using @testcontainers with a fresh container per integration test. 🐢

Switched to a single shared container + resetting the DB between tests using a Postgres template:

CREATE DATABASE test_db WITH TEMPLATE test_template;

9x faster tests. 🚀😅 #postgres #testcontainers

Looking forward to ai engineer Melbourne conference tomorrow. Lots of great talks lined up. #aiengineer

Cleanroom v0.10.0 is out.

Shared Cleanroom servers are a lot more usable now: OIDC auth, owner-scoped access, DeepSec hardening, and suspend/resume with automatic wake-on-use.

The Cursor CLI is quite good to use however it seems to be stuck at 1.0.0, with some overlap with latest cursor 3.x features, but not all. History and some MCP features seem borked, even though they share the same config path...

Seems disjointed or just me? @cursor_ai #ai 😞

[Mark Wolfe 🐺 @wolfeidau]

@kylegalbraith Whats the bet little changes, and developers just need to work around it... There is so much inertia around package managers, the only thing that changes them is a fork/rewrite/shift.

[Mark Wolfe 🐺 @wolfeidau]

Currently learning Rust so I can hack on MCP, and Agent related projects. Biggest challenge after getting the basics is just building momentum enough to start using the language day to day on a project.

Once I get over that hump it should be fine. #rust

[Mark Wolfe 🐺 @wolfeidau]

It still blows my mind when I get an agent to run a security review, and it switches seamlessly to destroying my service and providing a curated list of issues.

Especially given it just wrote this code, feels like I am getting farmed here. AI treadmill life.🐁🤔🤦‍♂️ #ai #agents

[Mark Wolfe 🐺 @wolfeidau]

So

Compacting conversation…

Is the new compiling?

why are you so slow?!⏳🤦‍♂️

[agrim singh @agrimsingh]

i can’t believe it.

you can really just do things at @aiDotEngineer singapore

[Mark Wolfe 🐺 @wolfeidau]

Loving the keynote for @aiDotEngineer Singapore with Dr Vivian Balakrishnan. 100% agree, learn by doing. #ai #agents https://t.co/FNJmr59eR7

@matteocollina AWS scaling when paired with other services like ECS, has many of layers of latency, it is a bit of a mash up. Can be very frustrating... ⏳⏳⏳⏳⏳

[Lachlan Donald @lox]

Going to be in Sydney for AWS Summit for the next few days if anyone wants to talk CI/AI or @buildkite!

[Mark Wolfe 🐺 @wolfeidau]

@kebabman Zig is a nice language, simple, fast, and practical. That said a lot changed in the recent 0.16 release.
The big plus is cross platform builds. I am bouncing between Zig and Rust, will probably end up on Rust as it is more stable and more resources. Fun either way.

[Mark Wolfe 🐺 @wolfeidau]

Sunday has evolved into coffee, baking and learning new programming languages. Currently rewriting the same thing in Rust, and Zig, really interesting comparing solutions, build tools while using an LLM to learn rather than just produce. #AI #sunday

[Mark Wolfe 🐺 @wolfeidau]

In a holding pattern for Operational issue - Amazon Elastic Compute Cloud (N. Virginia) to be resolved...

Tough day(s) for people at AWS, and on callers everywhere. #AWS 🙏

👻Is it just me, or are Agent Skills spooky?

Skills can:
• fetch remote content
• Register subagents
• Create Hooks
• Hide instructions in Unicode

Cleanroom 0.7 is out.

Cleanroom runs repo workloads inside policy-controlled microVM sandboxes (linux and macOS): explicit network egress, host-held credentials, reproducible checkouts, and cached dependency traffic.

0.7 makes that usable for real dev loops: workspace sync, port exposure, stage-scoped egress, and reusable dependency/service outputs.

@swyx @mattpocockuk @aiDotEngineer Really enjoyed the keynote talk, 10/10 for inspiring me to focus on the fundamentals more. 😅
