Great video, thanks @siaw23

[Emmanuel (sub to my Rails YouTube) @siaw23]

I created a video about a new Rails feature: Rails Query. This feature is slick and your AI doesn't know about it yet. Thank you @lewispb.

'rails query' produces an Active Support Notification, `query.rails`. Subscribing to that enables logging and later auditing. Here's a PR in Console 1984 to subscribe to it, to start logging queries made (incl. which agent and user made them).

This Week in Rails:

A new `rails query` command lands: run read-only ActiveRecord queries from the command line and get structured JSON output with columns, rows, pagination metadata, query time, and generated SQL. Subcommands include `query schema`, `query models`, and `query explain`.

Also: static CSS and HTML files now include `charset=utf-8` in Content-Type, new Rails apps get a PWA offline fallback page, and ParameterFilter gains O(1) hash lookup for exact-match regexp filters.

Read all that and more in this week's newsletter: https://t.co/Hpw8t2JQaK

“rails query” is a great way to have your LLM / Claude / agent of choice query your production database. Read-only with a hook for logging and auditing. Works well with “kamal app exec” and Console 1984. Skill and blog post coming soon!

i'm seeing a new problematic behavior emerge in medium-big companies because of ai

somebody notices a performance issue or missing case in a feature they don’t own or maintain

instead of creating a ticket, they try to be nice and prompt their way to a PR

very nice but…

[Lewis Buckley @lewispb]

Use case is: "Can I go out on my boat today?" 😎

It's a bit niche, but if there's any Tidbyt owners in the UK interested in tide times, sea state, and wind speed, I've got you covered. https://t.co/CFMimbDQVc

@eileencodes "Engineering rigor is more important in the AI world than it was before." - yes!

Open source + money is a tricky path, full of dead ends.

I have seen a model that works at 37signals: build and sell a product, then open-source the tech behind it.

The product is the anchor and aligns incentives: open source serves the product, and the company sustains itself from it.

Just the last 5 years of 37signals open source is 🤯: https://t.co/lHDtxhYRCr

I wish we had more of this in the industry.

most agent best-practices are human best-practices too. docs, safeguards, bug repro steps etc.

[Mullvad.net @mullvadnet]

The UK has announced plans to fast-track legislation requiring “age verification for VPN use”. The correct term, however, is not age verification but identity verification.

A law like this would require everyone to identify themselves in order to use a VPN. This would pose a risk to whistleblowers, violate human rights, and represent yet another step toward an authoritarian society.

@usewhawit @ilyesm @dhh @vigilbase Oh and re: latency monitoring I want to do more work there so that Upright has a better performance monitoring set up OOB.

It does report web vital metrics via Playwright probes but I want to flesh that out more.

[Lewis Buckley @lewispb]

@usewhawit @ilyesm @dhh @vigilbase Yes, we warn on partial failure and page on total failure.

Each Prometheus / Alertmanager alerts independently to PagerDuty. PagerDuty de-dupes alerts.
