Mangle – a language for deductive database programming

news.ycombinator.com Unknown 2025-11-20 00:55:35

Mangle Mangle is a programming language for deductive database programming. It is an extension of Datalog, with various extensions like aggregation, function calls and optional type-checking. Deductive database programming is useful for bringing data from multiple data sources together since it enables us to represent and query that data in a uniform way. It can also be used to model domain knowledge, similar to machine-readable ontology but without being restricted to binary predicates. Data

Teeth whitening kits aren't exactly what most people would call riveting. I must say I was blown away by the entire Smile Brilliant process and package. I wasn't aware you could get custom-fitted whitening trays anywhere other than a dentist's office, but you can with Smile Brilliant. Wearing these whitening trays is just like wearing a retainer. They fit perfectly to your teeth because they're designed using putty impressions you make of your teeth. The process works like this: You order a kit

For Iris Murdoch, morality is about love, not duties and rules

Being in love is one of the most profound experiences we can have, one that can powerfully move us and irrevocably change the way we see ourselves, one another, and even the wider world. Literature and film often explore romantic love’s capacity to move us and radically alter our world (think of Romeo and Juliet, for instance), but this experience is not limited to romantic love: parents sometimes speak of experiencing overwhelming love at the first sight of their children, for example.

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter.

The Folk Economics of Housing

Abstract Why is housing supply so severely restricted in US cities and suburbs? Urban economists offer two primary hypotheses: homeowner self-interest and political fragmentation. Homeowners, who outnumber and have organizational advantages over renters, are said to lobby against development to protect their property values. The fragmentation hypothesis emphasizes that development's negative externalities are borne locally while most of the benefits accrue regionally or nationally, leading local
