Coq proof assistant

Compare

  Analyzed about 16 hours ago

Coq is a formal proof management system: a proof done with Coq is mechanically checked by the machine. In particular, Coq allows: * to define functions or predicates, * to state mathematical theorems and software specifications, * to develop interactively formal proofs of these theorems, * to ... [More] check these proofs by a relatively small certification "kernel". [Less]

NIP2

Compare

  Analyzed about 4 hours ago

nip2, the "free love child of Photoshop and Excel," is the GUI of vips. You don't directly edit images --- instead, like a spreadsheet, you build relationships between objects. nip2 actively manages these relationships: if you change an object property, the change is propagated "spreadsheet-style." ... [More] Like vips, nip2 is fast and needs little memory. You can comfortably work with multi-gigabyte images on very modest hardware. In addition to the visual programming interface accessible through the GUI, nip2 has command-line and batch modes. It even has its own functional programming language (for writing extensions).

Open Server Platform

Compare

  Analyzed 1 day ago

Open Server Platform (OSP) is a system to abstract away all the boilerplate code from developing scalable server daemons designed to run on multiple machines. It allows developers to just focus on writing the server logic in a XML file using Erlang syntax which then gets run by OSP on a number of machines, replicating state between them.
