Current take on working with coding agents: Use them as an extra level of abstraction for the making, not for the made.

Moreover, it seems to me that there is a third option beyond the “don’t look at the code” vibe coding approach and “big design up front” spec-driven development. That third option is an agent-based workflow, which I’d characterize by:
Vibe coding is irresponsibly building software through dice rolls, not caring what code is produced
What about when engineers at the top of their game use AI tools responsibly to accelerate their work?
I propose "vibe engineering"!

I feel like vibe coding is pretty well established now as covering the fast, loose and irresponsible way of building software with AI—entirely prompt-driven, and with no attention paid to …

A blog post I'd like to write if I had the time (or a maintained blog for that matter): "The Role of Automatic Testing in Agentic Coding" or maybe "Techniques for Test-led Brownfield Development with Coding Agents"...

Wonder what this classic means for the constant code review we do when working with AI and the push towards having agents make larger changes on their own.

If you've got a blog where you (at least sometimes) write Ruby-related posts, please reply with a link to your RSS feed below.
I am going to try to start keeping an eye on those as well and sharing interesting stuff I find from time to time.

We’re trying a rather radical new approach at Piccalilli by doing real world projects — for real clients — in the open. This gives us a context to provide genuine high quality, real world education for free at the point of entry.
We need your support to do free projects for good causes and publish free high quality education

Here's what rendering React Server Components is gonna look like in Parcel. Just point it at your server entry point, use any server framework/router/libraries you want, and render your components. Coming soon! 👀

Last school day before the holidays. Shall we play a game? In the replies, list ONE benefit of Test-Driven Development that nobody's listed yet. I'll go first.
Continuously working (shippable) software.
Your turn :-)

Ruby is fun.
I think I may have come up with the most cursed way to implement that in userland 😅

Also, I want to make more use of the fact that a core part of the Rails application I'm working on day-to-day is open source at github.com/codevise/pag.... Ten years of development on a real-world app should give me something to talk about.

I always liked Matt Swanson's #RealCodeFriday tweets. Let's try to get something similar started here.
#RealCodeFriday When building query objects or methods that perform more intricate queries, I often find myself wanting to preload different data based on where the query is used. Here's one approach that has been working well for me:

What's the best way to discover content related to a specific topic on here? For example, I'd like to find more posts related to the Ruby programming language, but as a search term it mainly brings up drawn characters named Ruby.

So far this appears to be working embarrassingly well for me...
Triggered by this post, I just added a site search shortcut to my Chrome config that makes "tw" open bsky.app.

Feels good to interact with social media again without the guilty conscience of supporting something you don't want to support. Been a while.
