Define the tests first, then run the bash script and it will iterate on https://t.co/XusAbSCLne until the tests all pass

@hjwp I've been eating this since I was a child. The finest of flavours.

[Meg Davis @MegLivInsideOut]

This is wrong on so many levels.

[Brandon Rhodes @brandon_rhodes]

If this poorly-designed feature is really added to Python, we lose a principle I’ve always taught students: “if you see an undocumented constant, you can always name it without changing the code’s meaning.”

The Substitution Principle, learned in algebra? It’ll no longer apply.

Great work everyone! Can't wait to use it.

@IanFooteTech @carltongibson @aymericaugustin @seddonym And 8 days after the blog post, durable=True is committed to master... we can already see on the dev version of the docs here: https://t.co/yRGFuHNyvW

Go team!

@IanFooteTech Thanks Ian! This is why I love open source.

[David Seddon @seddonym]

@aymericaugustin @codeinthehole Much better, thanks. I've updated the post to use that approach now.

#django developers! Do you use transaction.atomic? If so, you should read this https://t.co/i5rGcqJK35

[David Seddon @seddonym]

@aymericaugustin @codeinthehole Oh @aymericaugustin I'm sad I made you sad! As I hope I made clear, I'm not criticising your design: it's great. But I do think we need to help people understand how to use it correctly.

@jugmac00 @brianokken @testandcode Glad you enjoyed it!

I work in a team of around 40 developers, but it is not structured particularly hierarchically. Definitely there are some differences of opinion, particularly when it comes to the DRY principle. So yes, definitely these are subjective principles...
