In fact, one approach could be to sell a premium version with collaborative tools (such as sharing workspaces with colleagues).

Thanks! I'll certainly give it a try. Not sure what the business model should be, though.

You may want to take some inspiration from prezi.com. One could write prezi-like HS workspaces to document some particular workflows. You would want the possibility to add text to the canvas (outside of the code editors), and allow zooming in/out from editors. This could be a premium feature that large companies want to pay for.

I found this page interesting.

Following a HN post on the IDP-Z3 knowledge base system yesterday, you might be interested in a talk I gave at Fosdem earlier this year.

Yes. It uses a more convenient language than SMT-Lib to express "knowledge", and offers more functionality.

Thanks for the feedback. We'll see how we can improve the communication.

Quick response: with pypi, you can only install the reasoning engine. By cloning the repository, you get the full suite of tools, including the "interactive consultant".

Hi, I'm one of the main devs. TLA+ is useful to prove properties of programs. By contrast, IDP-Z3 is a reasoning engine that can be used as a module in a program. It is closer to a constraint solver, but offers more functionality than a traditional CSP solver. For example, it can compute what are relevant questions, given some inputs. This is useful to build "interactive consultants".

For example, you give IDP-Z3 the formula that links a tax-free amount, a tax rate and a tax-included amount, and the values of any two of its parameters, and it will compute the missing parameter. You do not need to write 3 different formula, one for each case. If you give him only one parameter, it will say that the other two parameters are relevant.

You are missing the complaint he filed because he was a victim of retaliation. This is first hand evidence that the inspector general of the intelligence community found credible and urgent, and the main point of the story.

Surely you are not using neural networks ! They are quite magical too !

What do you mean, 'they get hairy really fast' ?

Does it support linking to another file in the same directory ?

Elinor Ostrom would agree. She received the Nobel prize in Economics in 2009 (after OP's article) for her work on "Common Pool Resources" and the institutions that successfully manage common resources.

Noticing that commons are not always managed to tragedy, as noticed by OP's article, her motto was "A resource arrangement that works in practice can work in theory".
