Continuous Deployment With Jenkins And Rex

Continuous Deployment With Jenkins And Rex

Continuous Deployment With Jenkins And RexIn this tutorial I will show you how to do continuous deployment with jenkins
as a ci tool and Rex as a deployment tool. Together, we will set up Jenkins,
the build and test process, a Subversion repository and our example Perl App.This tutorial can be used with Java-, PHP-, Rails-, … projects as well. But
for simplicity I’ve chosen Perl.This howto focuses on Ubuntu LTS 11.04 but it can also be done with other Linux
Distributions. For Jenkins you just need a Java Environment and for Rex you just
need Perl 5.8 (i recommend >=5.10) and some Perl Module

How to run your own Git server with GitlabHQ on Ubuntu 14.04Version 1.0Author: Srijan KishoreThis document describes how to install and configure Git and GitHub. These are great tools to manage and administer a whole host of Git repositories and the associated permissions. So, these remain true blessings for users writing open source software, however, when writing a closed source software may not be comfortable in trusting the code to a third party server. To gain the much-needed flexibility and control on stuff like Github/BitBucket without hosting the git repositories on servers that lie ex

Installing NLTK and using it for Human language processing

Installing NLTK and using it for Human language processingNLTK stands for “Natural Language Tool Kit”. It is a python programming module which is used to clean and process human language data. Its rich inbuilt tools helps us to easily build applications in the field of Natural Language Processing (a.k.a NLP).A corpora is a set of words present in a particular language and NLTK provides over 50 different corpora to work on and provides core libraries like POS tagging, End of speech tagging, tokenization, semantic reasoning, classification, etc. Following is a brief description of the 5 main fea

Distributed parallel programming in Python : MPI4PY

Distributed parallel programming in Python : MPI4PY1 IntroductionMPI stands for Message passing interface. An implementation of MPI such as MPICH” or OpenMPI is used to create a platform to write parallel programs in a distributed system such as a Linux cluster with distributed memory. Generally the platform built allows programming in C using the MPI standard. So in order to run Parallel programs in this environment in python, we need to make use of a module called MPI4py which means “MPI for Python”. This module provides standard functions to do tasks such as get the rank of processors, send

Shell Scripting Part 3: Decision Control Structures in Shell Scripts

Shell Scripting Part 3: Decision Control Structures in Shell ScriptsHi! We already covered the basics of shell scripting such as accepting inputs, process data through arithmetic operations and generating and displaying output in the previous parts of this tutorial (part 1 and part 2). In this part, we will go deeper to a more advanced topic in a programming language — making decisions in a program, but this time we will do it using bash shell. Let’s get started!IntroductionMost of our programming languages today are able to make decisions based on conditions we set. A condition is an express
