The `TRUNCATE TABLE * CASCADE` root cause in Linear's post-mortem is a super easy mistake to make, and even harder to spot in review.

So to stop us ever making the same mistake as I have added a
Semgrep rule to our CI step.

One great thing about it is that it differentiates between "monitor", "comment", and "block".

So you can test rules without anyone seeing anything, or roll them out as comments only so they appear on PRs as a GitHub comment. Then only use "block" for ones you know are legit.

An example is worth a thousand words, so here is it writing a #django rule to ban implicit ordering of querysets by defining the ordering on the model.

Written, tested and sent to CI within 60 seconds.

Using ChatGPT4 to write Semgrep .yaml rules is the fastest way we've ever had to add language/framework -agnostic linting rules.

The friction is so low that a new rule can be in place in less than 2 minutes, and that thing never needs to be discussed again.

So good.

Says it all. Many thanks @charliermarsh & team.

What moving to `ruff` looks like for our dependency graph.

(pre-)commits just got a whole load faster ⚡️

Ruff stands on the shoulder of giants – so a huge shout to all the maintainers of the projects on this list, without you and the cataloguing of all the meticulous rules none of it would have been possible. Moving on but not forgotten.

I highly recommend reading how Copilot engineers its LLM prompt because once you know what it's doing under the hood - you can take action to help guide it.

It wasn't immediately apparent during testing on staging, or even in general usage of the platform - which makes me suspect it's a contention issue in some form. Hopefully will get some time to look into it soon and write it up.

Yesterday, on Django 4.2, we bumped #psycopg from v2 to the v3 but suffered an increase in locks & connection waiting during some periods of heavy work on the same hardware (Heroku pg with server-side pgBouncer).

Operational reasons (shipping!) stop us investigating this in more depth right now but thought this warning may be of help to someone.

Django 4.2 brings one change I don't see anyone talking about: the default admin save & delete buttons have swapped sides.

If you're wondering why, it was part of a change to fix the tab ordering. You can read more here: https://code.djangoproject.com/ticket/33728

It'll take some getting used to after 14 years!

If your team have been investing in writing decent pull requests/commit messages - your entire team is about to get levelled up by LLMs.

Never has investing in the written word as related to code been more important than it is about to be.
