Jay Parlar's Strange Loop talk shows how model checkers such as Alloy can find complex bugs in a system's design without running or reading any code. He walks through modeling architectures and checking every possible sequence of operations, including a real security bug and a UI feature-interaction bug.

Why Hacker News points people here: HN commenters point to it as the best practical introduction to Alloy and to lightweight formal modeling.

“There was a fantastic talk at strangeloop this year on Alloy”

Talk using Alloy to find a serious security bug and UI feature-interaction bug

Full comment

There was a fantastic talk at strangeloop this year on Alloy: this video . The speaker used it to find a serious security bug in their live code and a feature interaction bug in their UI that had meant they had been writing broken code for the past _year_. (full disclosure I'm referenced towards the end)

“I was exposed to alloy by this wonderful video”

Introduced commenter to Alloy; applicable to core business software

I was exposed to alloy by this wonderful video: "Finding bugs without running or even looking at code" by Jay Parlar this video I believe the general idea could be applicable in practice for core parts of most businesses software. So now I'm very interested in real world accounts of using alloy like this. Anyone have other posts like this one or experiences to share along these lines?

Shows iterative Alloy modelling: generate examples, spot errors, add rules

There's a great talk from StrangeLoop[0] where a presenter uses Alloy modelling in exactly the same manner: - generate a couple examples - see something wrong - add a rule - repeat [0] this video
