Lets Understand the Ruby programming world in 5 mins?

Ruby
Ruby is a dynamic, interpreted, reflective, object-oriented, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro “Matz” Matsumoto in Japan. The Currnet most latest stable release is Ruby 2.5.

Gem – A Ruby Package
A Gem is a Ruby application package which can contain anything from a collection of code to libraries, and/or list of dependencies that the packaged code actually needs to run.

Gems are formed of a structure similar to the following:

/[package_name] # The main root directory of the Gem package.
|__ /bin # Location of the executable binaries if the package has any.
|__ /lib # Directory containing the main Ruby application code (inc. modules).
|__ /test # Location of test files.
|__ README #
|__ Rakefile # The Rake-file for libraries which use Rake for builds.
|__ [name].gemspec # *.gemspec file, which has the name of the main directory, contains all package meta-data, e.g. name, version, directories etc.

One of the tools we will be using for creating Gems is Bundler.

Bundler
Bundler a gem to bundle gems. Bundler makes sure Ruby applications run the same code on every machine.

It does this by managing the gems that the application depends on. Given a list of gems, it can automatically download and install those gems, as well as any other gems needed by the gems that are listed. Before installing gems, it checks the versions of every gem to make sure that they are compatible, and can all be loaded at the same time. After the gems have been installed, Bundler can help you update some or all of them when new versions become available. Finally, it records the exact versions that have been installed, so that others can install the exact same gems.

RubyGems – A Package Manager
RubyGems is the default package manager for Ruby. It helps with all application package lifecycle from downloading to distributing Ruby applications and relevant binaries or libraries. RubyGems is a powerful package management tool which provides the developers a standardised structure for packing application in archives called Ruby Gem. The webiste is https://rubygems.org/

Rake
Rake is a Make-like program implemented in Ruby. Tasks and dependencies are specified in standard Ruby syntax. you must write a “Rakefile” file which contains the build rules.

Rails
Rails is a web application development framework written in the Ruby programming language. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. It allows you to write less code while accomplishing more than many other languages and frameworks. Experienced Rails developers also report that it makes web application development more fun.

bower
Web sites are made of lots of things — frameworks, libraries, assets, and utilities. Bower manages all these things for you. Bower can manage components that contain HTML, CSS, JavaScript, fonts or even image files. Bower doesn’t concatenate or minify code or do anything else – it just installs the right versions of the packages you need and their dependencies.

yarn
Yarn caches every package it has downloaded, so it never needs to download the same package again. It also does almost everything concurrently to maximize resource utilization. This means even faster installs.

If i have missed any tools which is important of Rudy ecospace, please mentioned in the comments sections.

Chef Client
The Chef client works with the Chef server to bring nodes to their desired states with policies you provide as recipes. The chef-client executable can be run as a daemon. A chef-client is an agent that runs locally on every node that is under management by Chef. When a chef-client is run, it will perform all of the steps that are required to bring the node into the expected state, including:

  • Registering and authenticating the node with the Chef server
  • Building the node object
  • Synchronizing cookbooks
  • Compiling the resource collection by loading each of the required cookbooks, including recipes, attributes, and
  • all other dependencies
  • Taking the appropriate and required actions to configure the node
  • Looking for exceptions and notifications, handling each as required

Chef Development Kit

Chef Backend
Chef High Availability makes it easy to build high-availability Chef clusters on any infrastructure.

Chef Manage
Chef Manage is an Enterprise Chef add-on that enables a web-based user interface for visualizing and managing nodes, data bags, roles, environments, cookbooks and role-based access control (RBAC).

Kitchen or Test Kitchen
kitchen is the command-line tool for Kitchen, an integration testing tool used by the chef-client. Kitchen runs tests against any combination of platforms using any combination of test suites. Each test, however, is done against a specific instance, which is comprised of a single platform and a single set of testing criteria.

“Test Kitchen is an integration tool for developing and testing infrastructure code and software on isolated target platforms.” It creates test machines, converges them, and runs post-convergence tests against them to verify their state. Test Kitchen is written in Ruby. It has a plugin system for supporting machine creation through a variety of virtual machine technologies such as vagrant, EC2, docker, and several others. Test Kitchen makes it easy for Chef developers to test cookbooks on a variety of platforms. It uses busser to install post-convergence integration test tools such as Serverspec or BATS that actually perform the tests.

foodcritic
Foodcritic is a helpful lint tool you can use to check your Chef cookbooks for common problems.
http://www.foodcritic.io/

ChefSpec
ChefSpec is a framework that tests resources and recipes as part of a simulated chef-client run. ChefSpec tests execute very quickly. When used as part of the cookbook authoring workflow, ChefSpec tests are often the first indicator of problems that may exist within a cookbook.
ChefSpec is packaged as part of the Chef development kit. To run ChefSpec
$ chef exec rspec
https://docs.chef.io/chefspec.html

RuboCop
Rubocop is a Ruby command-line tool that performs lint and style checks based on the community driven Ruby Style Guide. It performs static analysis of any Ruby code, which includes Chef recipes, resources, library helpers, and so forth. Rubocop can be configured via .rubocop.yml to exclude certain rules, and it can be run with “–lint” to perform only lint checking, excluding all style checks. Rubocop is used in the Chef community in cookbooks to make contributions more consistent and easier to manage.

Serverspec
Serverspec is an “outside-in” integration test framework. It is platform and tool agnostic, and is used by other configuration management systems to verify systems are configured as desired. It checks the actual state of the target node by executing commands locally, via SSH, via WinRM, or other remote transports. Serverspec is implemented in RSpec, and uses RSpec test syntax.

General SCM Interview Questions

by scmgalaxy KInterview Questions & AnswersLeave a Comment on General SCM Interview Questions

The previous chapters outlined the state of CM technology from the standpoint of a spectrum of concepts underlying automated CM, and from the standpoint of the reflection of some of these concepts in commercial CM products. Clearly, no CM product supports all CM concepts; similarly, not all CM concepts are necessary in the support of all possible end-user requirements. That is, different CM tools (and the concepts which underlie these tools) may be required by different organizations or projects, or within projects at different  phases of the software development life cycle. This observation, coupled with the observed,continuing industry effort to adopt computer-aided software engineering (CASE) tools, leads us to conclude that integration is key to providing automated CM support in software development environments.
In this chapter we define what we mean by integration by way of a three-level model of integration. We illustrate where CM integration fits into this three-level model.  e then describe the advantages and disadvantages of current approaches to achieving integration in  software development environments. We close with a brief discussion on the relationship between future integration technology and the three levels of integration.

CM Services in Software Environments: A Question of Integration

There is no concensus regarding where CM services should reside in software environment architectures, despite the diversity of approaches that have been explored. For example, CM services have been offered via:

· Tools such as RCS, SCCS, CCC.
· Operating system extensions at the file-system level such as DSEE and NSE.
· Shared data models such as in the CIS specifications [18] and the PCTE PACT [53] environment.

A further complication is the emergence of a robust CASE tool industry, wherein many popular CASE tools provide their own tool-specific repository and CM services. As a result, CM functions are increasingly provided by, and distributed across, several CASE tools in an environment.
We have found it useful to think of integration in terms of a three-level model. This model, illustrated in Figure 5-1, corresponds to the ANSI/SPARC [48] three-schema  pproach used to describe database architectures. A useful intuition is that this correspondence is more than accidental. The bottom level of integration, called “mechanism” integration, corresponds to the ANSI/SPARC physical schema level. Mechanism integration addresses the implementation aspects of software integration, including, but not limited to: software interfaces provided by the environment infrastructure, e.g., operating system or environment framework interfaces;

software interfaces provided by individual tools in the environment; and architectural aspects of the tools, such as process structure (e.g., client/server) and data management structure (derivers, data dictionary, database). In the case of CM, mechanism integration can refer to integration with CM systems such as SCCS, RCS, CCC and DSEE; and CM implementation aspects such as transparent repositories and other operating-systems level CM services.

The middle level of integration, called “services” integration, corresponds to the ANSI/SPARC logical schema level. Services refers to the high-level functions provided by tools, and integration at this level can be regarded as the specification of how services can be related in a coherent fashion. In the case of CM, these services refer to elements of the spectrum of concepts discussed in chapter 3, e.g., workspaces and transactions, and services integration constitutes a kind of unified model of CM services.

The top level of integration, called “process” integration, corresponds to the ANSI/SPARC external schema (also called “end-user”) level. Process integration can be regarded as a kind of process specification for how software will be developed; this specification can define a view of the process from many perspectives, spanning individual roles through larger organizational pespectives. In the case of CM, process integration refers to policies and procedures for carrying out CM activities.

Integration occurs within each of these levels of integration; thus, mechanisms are inte- 34 ATR grated with mechanisms, services with services, and process elements with process elements. There are also relationships that span the levels. The relationship between the mechanism level and the services level is an implementation relationship: a CM concept in  he services layer may be implemented by different tools in the mechanism level, and conversely, a single mechanism may implement more than one CM concept. The relationship between the services level and the process level is a process adaptation relationship: different CM services may be combined, and tuned, to support different process requirements.

image

This three-level model provides a working context for understanding integration. For the moment, however, existing integration technology does not match exactly this somewhat idealized model of integration. For example, many services provided by CASE tools (including CM) embed process constraints that should logically be separate, i.e., reside in the process level. Similarly, tool services are often closely coupled to particular implementation techniques.

The level of adaptability required of integrating CM—both in terms of adaptability for projectspecific requirements as well as adaptability to multiple underlying CM
implementations—pushes the limits of available environment integration techniques. The following sections describe the current state of integration technology and its limitations. The next chapter discusses how future generation integration technology can address these shortcomings.

With the introduction of Iceberg 1.2, it is no more required to install the Developer tools. If you prefer to use the SplitForks tool instead of the goldin tool, you still need to install the Developer tools.

Top 5 Open Source Code Management tools

by scmgalaxy KSource Code ManagementLeave a Comment on Top 5 Open Source Code Management tools
top-5-open-source-code-management-tools
The old way of software development where the release engineers ran from one mates to another mates to keep track on Developers to know which module they are working and when they changed something in the code or which bugs has been tracked or fixed. No doubt, that process was pathetic, stressful, filled with issues and errors.
But, now things have changed. This is the era of DevOps where everyone works as a Team and collaborate with each other and use various tools in the Software Development Lifecycle. So, today we are going to discuss on one of the most important tool called by name Code Management Tools. In this article we will see top 5 open source code management tools which are mostly used by DevOps professionals these days.
But before going further lets see what is source code management?
Code management is actually a process of handling or managing changes to source code over time with the help of softwares or tools. These softwares keeps track of every changes and modifications in the code which is made by developers frequently. If there is some kind of mistakes made by developers they can simply go back compare it with previously written code and fix the mistakes easily. With the help of code management tools Developers team can work on different features and on bug fixing simultaneously by changing code with out disrupting team members. In other words you can say It give developers the ability to work concurrently on files (in branches that may or may not converge) without conflicting each other and also give developers the ability to merge changes with other developers’ changes, to track and audit changes that were requested and made, to track bug-fix status and to perform releases.
So now the question is which code management tools to use. When you search for the options you will get hundred of tools in your search results. To make this job easy for you we have done some research and make this list of Top 5 Open Source Code Management tools.
