    El algebra boole / ley de morgan de la "puertas lógicas" tiene 2 estados ( 0 y 1 , con la con 2 NANDS tengo todo ) y la tautologia de las tablas se basa en esos 2 estados. Si pensamos en QBit ( |0> , |1> , |01>, |10>, .....) ), no hay tautologia clasica... se derrumba el álgebra de boole/morgan en este campo, salvo que sean reversibles las operaciones. Interesante el campo que se abre !!!!!! a investigar un poco mas del tema en lo que se refiera a superposición cuántica.

cloudera/cdk - 0 views

  •  
    "The Cloudera Development Kit, or CDK for short, is a set of libraries, tools, examples, and documentation focused on making it easier to build systems on top of the Hadoop ecosystem. The goals of the CDK are: Codify expert patterns and practices for building data-oriented systems and applications. Let developers focus on business logic, not plumbing or infrastructure. Provide smart defaults for platform choices. Support piecemeal adoption via loosely-coupled modules."

Slick 2.0.0 - 0 views

  •  
    "These are the major new features added since Slick 1.0.1: A code generator that reverse-engineers the database schema and generates all code required for working with Slick. New driver architecture to allow support for non-SQL, non-JDBC databases. Table definitions in the Lifted Embedding use a new syntax which is slightly more verbose but also more robust and logical, avoiding several pitfalls from earlier versions. Table definitions (and their * projections) are not restricted to flat tuples of columns anymore. They can use any type that would be valid as the return type of a Query. The old projection concatenation methods ~ and ~: are still supported but not imported by default. In addition to Scala tuples, Slick supports its own HList abstraction for records of arbitrary size. You can also add support for your own record types with only a few lines of code. All record types can be used everywhere (including table definitions and mapped projections) and they can be mixed and nested arbitrarily. Soft inserts are now the default, i.e. AutoInc columns are automatically skipped when inserting with +=, ++=, insert and insertAll. This means that you no longer need separate projections (without the primary key) for inserts. There are separate methods forceInsert and forceInsertAll in JdbcProfile for the old behavior. A new model for pre-compiled queries replaces the old QueryTemplate abstraction. Any query (both, actual collection-valued Query objects and scalar queries) or function from Column types to such a query can now be lifted into a Compiled wrapper. Lifted functions can be applied (without having to recompile the query), and you can use both monadic composition of Compiled values or just get the underlying query and use that for further composition. Pre-compiled queries can now be used for update and delete operations in addition to querying. threadLocalSession has been renamed to dynamicSession and the corresponding methods have distinct names (e.g. w

Rationale - Datomic - 0 views

  •  
    "Datomic is a distributed database designed to enable scalable, flexible and intelligent applications, running on next-generation cloud architectures. It does this by: Bringing declarative data manipulation into the application, and the data with it Getting time, process and perception right Process (writes) require coordination Perception (reads) require none The past doesn't change Leveraging immutability, and a sound model of state Datomic has: ACID Transactions Joins A sound data model A logical query language - Datalog Thus, Datomic avoids the compromises and losses of many NoSQL solutions. In addition, it offers flexibility and power over the traditional model in supporting: Hierarchy Multi-valued attributes Minimal schema Reliable operation on unreliable, ephemeral cloud instances Time Datomic avoids manual caching and replication, complex configuration, sharding (automatic or manual), logging, locking, latching and disk management of traditional servers."

Building microservices with Scala, functional domain models and Spring Boot - 0 views

      Muy buenos slides que muestran un posible modelo a adoptar para arquitectura de microservicios basados en event-sourcing. Imperdible. 
  •  
    "In this talk you will learn about a modern way of designing applications that's very different from the traditional approach of building monolithic applications that persist mutable domain objects in a relational database.We will talk about the microservice architecture, it's benefits and drawbacks and how Spring Boot can help. You will learn about implementing business logic using functional, immutable domain models written in Scala. We will describe event sourcing and how it's an extremely useful persistence mechanism for persisting functional domain objects in a microservices architecture."

Baratine | a distributed in-memory Java service platform - 0 views

  •  
    "Baratine is a new distributed in-memory Java service platform for building high performance web services that combine both data and logic in the same JVM. Say again? In Baratine, the data lives within the service and the service owns its own data. This means: the data is not owned by the database the data is not modified by another process the data is not separate and distinct from the service => The data sits right in the service in the same JVM, the same thread, and the same class instance."

OpenAPI-Specification/3.0.1.md at master · OAI/OpenAPI-Specification - 0 views

  •  
    " The OpenAPI Specification (OAS) defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined, a consumer can understand and interact with the remote service with a minimal amount of implementation logic."
