Are you stuck with two Git repositories or branches that have completely different histories, but you need to merge them? You may be hitting a roadblock because Git is designed to prevent this kind of operation by default. However, there’s a workaround for this, and it’s simpler than you might think.

The Problem: Unrelated Git Histories#

Imagine you’re working on a project where you have a main branch, and someone else has a completely separate project with its own history. Now, you want to combine both projects into a single repository. If you try to perform a regular git merge or git rebase, Git will likely stop you with an error message, something like:

What is the Ansible Provisioner in Packer?#

If you’re dabbling in the DevOps world, chances are you’ve come across Ansible and Packer. But how about combining them? The Ansible provisioner in Packer lets you run Ansible playbooks while creating your machine images. In simpler terms, it helps you set up your server environment automatically, just the way you like it, while Packer goes about its business creating a machine image.

Introduction#

SSHPass is a nifty little tool that lets you automate SSH login by bypassing the usual password prompt. While it’s super convenient for scripting, bear in mind that it’s not ideal for a multi-user setup due to security concerns. However, if you’re using it on your personal development machine, it’s pretty harmless.

How to Install SSHPass on Ubuntu#

Installing SSHPass on Ubuntu is as straightforward as it gets. All you need to do is open up your terminal and run the following command:

What You Need Before You Begin#

Operating System Requirements#

First things first, make sure you’re running one of the following 64-bit Ubuntu versions to install Docker CE:

• Ubuntu 18.04 (Bionic) - LTS
• Ubuntu 17.10 (Artful)
• Ubuntu 16.04 (Xenial) - LTS
• Ubuntu 14.04 (Trusty) - LTS

Docker CE is compatible with these architectures: x86_64, armhf, s390x (IBM Z), and ppc64le (IBM Power).

Note: For IBM Z and Power architectures, you’ll need at least Ubuntu 16.04 (Xenial) or higher.

In this post, we’ll break down the big data life cycle into its essential components, offering a roadmap for navigating this multifaceted landscape.

The Eight Key Challenges#

1. Capture: This is where it all starts. You can’t analyze what you don’t have, so capturing relevant data from diverse sources is the initial step. The challenge here lies in determining what data is useful and then finding effective ways to collect it.

When you’re working with Drupal 6, it’s sometimes necessary to inspect the data stored in a node’s field. This is especially useful for debugging or when you’re trying to understand the structure of the content better. One quick way to achieve this is by dumping the field contents as an array. In PHP, the var_export() function comes in handy for this purpose.

Here’s how to do it:

var_export(content_fields('field_name_of_the_field', 'name_of_the_content_type'));

In this snippet, replace 'field_name_of_the_field' with the actual name of the field you’re interested in and 'name_of_the_content_type' with the specific content type containing that field.
