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

Joone - Java Object Oriented Neural Engine - 0 views

  •  
    "Joone is a FREE Neural Network framework to create, train and test artificial neural networks. The aim is to create a powerful environment both for enthusiastic and professional users, based on the newest Java technologies. Joone is composed by a central engine that is the fulcrum of all applications that are developed with Joone. Joone's neural networks can be built on a local machine, be trained on a distributed environment and run on whatever device. Everyone can write new modules to implement new algorithms or new architectures starting from the simple components distributed with the core engine. The main idea is to create the basis to promote a zillion of AI applications that revolve around the core framework."

Running Secured Docker Registry 2.0 - Container Solutions - 0 views

  •  
    "The new Docker Registry 2.0 was released on April 16th, 2015. It was completely rewritten in Go with added support for the new Docker Registry HTTP API V2 (thus only working with Docker 1.6+), promising to provide faster and more secure distribution of images. If you work with Docker and for some reason decided not to use the public Docker Hub, a private Docker Registry is an essential part of your architecture. But even if you don't have private images, you will likely need to use your own registry in production/testing for efficiency. The default installation, however, runs without encryption and authentication. I was wondering what's involved in securing it. There is an official tutorial on how to configure TLS on a registry server. TLS/SSL is absolutely necessary for any secure setup, but I also wanted to enable an authentication mechanism. The Configuration Reference document describes two authentication options supported by Docker Registry itself: so-called silly and token solutions. The silly one is apparently only useful for very limited development use-cases. The token solution seems to be more serious, but because of the lack of documentation (at the time of writing), I decided to find an alternative approach to secure it. In this article I'm going to show you how to set up the Docker Registry 2.0 with username/password authentication and SSL using the official Docker Registry image and a custom configured nginx as a proxy server."

Microservices and PaaS - Part I | ActiveState - 0 views

  • Instead of building software that resembles our existing organizations, we should figure out how we want our software to look, then build the organization around that. Or reorganize it if it's already in place.

      Las implicancias de esta idea en nuestra organización...
  • When deploying a new feature, enhancing or fixing an existing capability, or deploying an experimental line of code, the previous code remains available and accessible. New code is deployed alongside the old code, with mechanisms in place to instantly route to one or another version.
  • Importantly, the old code is not replaced, but remains part of the system, and is kept running. If, as is often the case, the widespread introduction of the new feature results in unforeseen consequences, the feature flag can be toggled off, and the old version is instantly used instead.
  • ...13 more annotations...
  • In a microservices architecture, an application is comprised of a number of small, independent composable services that interact by way of an external published protocol, such as REST, or a messaging service.
  • Each service is focused on an individual targeted business capability, and thus its scope is minimized. For functionality out of scope, the microservice calls out to other microservices via the published protocol.
  • Small independent microservices can be built using the technology best suited for their requirements. No longer does every application component need to be built on a common company-mandated language and framework such as Java/Spring or Ruby on Rails.
  • Similarly, there's no reason to standardize on a single persistence layer across an entire application. Some microservices might best be served by Redis, others by Oracle.
  • Each microservice can be updated independently, no longer requiring the entire application to be redeployed.
  • Microservices drastically improve the time required to push out a new update, allowing a much more agile development process.
  • Many organizations consist of specialized silo teams (UI, database, API, etc) where costly handoffs and intercommunication are required to coordinate all the pieces of application construction. These handoffs cause overhead, and the need for them should be eliminated.
  • With small teams, each focused on an individual microservice, Netflix enables developers to push code to production, instead of getting mired in a complex deployment process involving several teams.
  • With microservices, the old IT mindset just doesn't work.
  • A centralized IT department cannot possibly cover the wide array of technologies spanning all microservices.
  • Instead a DevOps structure, where each team is responsible for the management of the corresponding microservice, is essential.
  • Enable developers to concoct systems of their choosing with minimal or no interaction from IT, management, VPs, hardware or other groups. "Self Service" is one of the major capabilities offered by the cloud and there's every reason to take advantage of this.
  • Now, IT can be considered as a cloud API available to the developer on-demand 24x7, instead of a complex, process-mired division hidden behind obscure process.

Docker Just Changed Windows Server as we Know It - The New Stack - 0 views

  •  
    "But when Mark Russinovich, Microsoft's CTO for Azure, took the stage at Build 2015 in San Francisco Wednesday morning to demonstrate how containerized microservices applications work in Windows Server. [...] As is his wont, he dove right in to a demonstration of using Docker Build (on a PowerShell command line) to package and deploy an ASP.NET web site as a Docker container. [...] He took only a few seconds to package the web site into a container image, then he ran the package with the docker run command. [...] And then he paused, took the temperature of the room, and may have recognized that Windows developers may have been completely confused by what they were seeing. [...] So Russinovich asked for a show of hands of folks in the room who might have heard of something called Linux. (Don't worry, he's done this before.) [...] He then used a new build of Visual Studio, running in Windows, to publish the container to the Linux host. He then proceeded to debug the running Linux app, including setting a remote breakpoint, from Visual Studio. [...] Without saying so explicitly, Mark Russinovich was obsoleting much of Windows Server before developers' eyes."

The New Stack and Linux Foundation Survey: OpenStack and Docker are The Most Popular Op... - 0 views

  •  
    "OpenStack and Docker will continue to dominate the open source cloud discussion. But Docker may prove to gain the most as it is also breeding a diverse ecosystem of open source projects. OpenStack is primarily contained (no pun intended) to the development of its own cloud operating system. It does integrate with OpenShift, for example, but for the most part the different groups within OpenStack do the lion's share of development. Docker's influence is such that it is affecting the overall open source community. The projects that are closely tied to Docker, such as Ansible, will continue to grow as developers seek tools to use with the fast growing container technology."

bandicoot - having fun with structured data - 0 views

  •  
    "Bandicoot is an open source programming system with a new set-based programming language, persistency capabilities, and run-time environment. The language is similar to general purpose programming languages where you write functions/methods and access data through variables. Though, in Bandicoot, you always manipulate data in sets using a small set-based algebra (the relational algebra)." "Here are the main features:   - functions are automatically exposed via HTTP using CSV for data, e.g. /List, /Append  - supports persistency via global variables (with transactions and ACID)  - can run on multiple computers to scale up the read throughput  - built in operators from the relational algebra with a simple syntax, e.g. "+" (union), "-" (minus)  - small binary ~100KB"

Bottom vs. top posting and quotation style - 0 views

  •  
    "What is the reason to quote at all? Consider it. It shouldn't be to allow people to scroll down to see all earlier discussions. If the news client is a bit smart, fetching the older articles from the server should be just as easy as to "scroll down". If a thread goes forth and back some times and earlier quotes accumulate, an article including all those quotes might get five-ten times larger than a posting without quotes, this wastes bandwidth and hard disk space. Therefore, IMHO, no quotes are far better than a posting at the top of all old quotes."

    "This is a maven plugin that adds a new packaging type ('scala-jar') to maven with a better default lifecycle. This lifecycle binds net.alchim31.maven:scala-maven-plugin:compile to the 'compile' phase by default while also retaining an invocation of maven-compiler-plugin. Additionally, com.vast:scala-surefire-maven-plugin:test is bound to the 'test' phase. This allows native and seamless use of ScalaTest in your build."
