Shredding files on Linux

The rm command easily makes files disappear from our file listings, but what does it actually do and how can we ensure that files are unlikely to be recoverable?A little background To understand what happens when you remove a file from a Linux system with rm, first think about inodes -- those intriguing data structures that keep track of all of a file's attributes -- often called "metadata" -- that describe the file. This includes its name, its owner and group, what permissions have been established and where the file's contents can be found on the disk.Next, think about Linux directories. While they take the appearance and character of folders (i.e., merely containers for holding files) they are actually files themselves -- files that include no more than the names and inode numbers of the files they "contain". So, what we get is a convenient way to think about directories and files in the same way you might think about the folders and paperwork in your file cabinets (if any of you still have one of those).To read this article in full, please click here

Automation for Success

Businesses with high growth, complex tasks and repetition, tend to rely on or require automation to fulfill business challenges. Introducing automation is not without challenges and sometimes they can be quite significant. Identifying success is one of the early crucial activities that creates a business alignment. The identification exercise highlights justification for one more decisions and the removal of friction. Some of the decisions are not easy to make and friction is not easy to experience without applying pressure to various parts of an organization.

What follows is a number of scenarios with some reasoning around the kind of challenges that you’re already facing or likely to face.

If the absolute reasons are known, accepted and aligned against, you have just laid one of the foundational layers for success.

Challenge: High Growth

Great news and bad news. You’re in a business under stress from high growth! Lots of great challenges to solve and high pressure from not having them currently solved.

With high growth businesses, engineers or administrators are not under threat of being “automated out of their job”. If you identify as one of these people, you have an opportunity to learn new skills, be rewarded for finishing projects Continue reading

IDG Contributor Network: A technology horror story: The day the marketing guy joined the hackathon

The fifth floor of the cafeteria at Cato’s Israeli office transformed last Thursday morning into a celebration of innovation, coding, and food. Our 2018 Hackathon was kicking off with a sumptuous breakfast buffet decorating the tables, and flags of the 10 project teams dotting the floor-to-ceiling windows that looked out onto southern Tel Aviv.Hackathons are usually meant for folks who know something about, well, hacking code. But the dynamic duo who conceived and ran the event – Eyal, our director of product management, and Jordana, Cato’s human resources manager – poked, prodded, and dare I say implored, every employee to join the festivities – and I do mean everyone. The call to sign up for Cato’s Hackathon wasn’t just limited those who could program in C but even employees who could spell with a C – all were encouraged to sign up.  Thankfully singing in C wasn't a requirement.To read this article in full, please click here

On the ‘web: Considerations in Network Complexity

One of my articles was published in the most recent Internet Protocol Journal:

Computer networks are complex—and getting more complex by the day. At one time, knowing the Internet Protocol (IP) was enough; today there are underlays, overlays, virtualized services, service chains, and a host of other technologies engineers need to plan around and for. With complexity on the rise, maybe it’s time to ask some fundamental questions, such as—what does complexity mean? Can complexity be solved? How can engineers manage complexity? @The Internet Protocol Journal

If you don’t subscribe to or read IPJ, you should—it’s a great source of information written by industry leaders and thinkers.

Getting Started: Using the Virtual Environment

Getting-Started-Using-the-Virt-Environment

Welcome to another Getting Started blog post! Previously, we did a four-part series on Ansible and Windows automation.

In this post, we are going to talk about how you can modify and use the Python virtual environment that is built when Red Hat Ansible Tower is installed. Before we get started, if you would like a dive deeper into the virtual environment you can find our documentation on it here .

Is This a Virtual Reality Test?

No, it is not. But one can dream, right? Before we get into this, let’s talk about what is created when you install Ansible Tower in regards to virtual environments.

Ansible Tower 3.0 and later uses virtualenv. Virtualenv creates isolated Python environments to avoid problems caused by conflicting dependencies and differing versions.

Ansible Tower creates two virtualenvs during installation–one is used to run Ansible Tower, while the other is used to run Ansible. This allows Ansible Tower to run in a stable environment and allows you to make changes to your Ansible environment.

The next topic we are going to talk about is modifying the Ansible virtualenv. But first, a warning to the adventurous. Modifying the virtualenv used by Ansible Tower is unsupported Continue reading

Rackspace, HPE expand on-premises cloud with pay-as-you-go Kubernetes

HPE and Rackspace are building on their alliance from last November, when they first introduced an OpenStack-based pay-per-use system designed to compete with public cloud providers.The two now offer pay as you go to Rackspace’s VMware and Kubernetes private cloud services. Rackspace launched its Kubernetes private cloud managed service just last month. The initial pay-as-you-go system was for standard server-side apps. This new feature adds Kubernetes container management as an option.Rackspace has deployed HPE’s new GreenLake Flex Capacity service to provide the pay-as-you-go pricing model. GreenLake is one of many programs by enterprise hardware vendors to provide on-demand pricing to companies looking to rein in data center costs.To read this article in full, please click here
