From Abacus to Containers — A Brief History of Computing
Do you remember the first time you touched the computer keyboard?
Do you remember the typewriter clanging sound?
Do you remember your first HTML rendered on the world wide web or your first “hello world” application?
Maybe you were a gamer, and you blew the cartridges on your family computer?
No doubt, your first lines of code rely on the combined outcomes of thousands of years of accumulated knowledge and wisdom.
I’m your host Kassandra Russel and today, we will navigate through history to discover how our ancestors made knowledge out of information. We’ll talk about the technologies that have marked contemporary and modern history. Then we’ll go back to modern times to talk about the first web server, virtualization, cloud computing, Docker, and Kubernetes. This is the tale of computing, in which humans are heroes, and their greatest weapon is the imagination.

History of Computing PtI
We learn and know (hopefully) a basic history of the world, particularly major events like the French revolution, the American Civil War, World War I, World War II (wow lots of wars), the Spaceage etc. It is important to understand the concepts of these and many other historical events. Being able to recall the start year or the exact details of how such events unfolded is one thing, but on a human level, it is more important to understand the rationale, lessons and philosophy of major events. Ultimately history teaches us what makes us innately human. Furthermore, understanding history helps us realise the how and why we operate in today. History provides the context for today. It makes today seem ‘obvious,’ ‘justifable’ and ‘logical’ given the previous events that unfolded.
So, following this thread of logic, understanding the history of computers should help us understand how we have got to today. A today when computers moderate much of our communication with one another. A today where computers and screens are stared at for many (and often a majority) of our waking hours (especially during Covid). A today where the thought of working, socialising or learning without a computer would be an affront and a disadvantage. Just as major events like World War II and the Cold War have greatly contributed to today’s political and social climate. I would argue computers influence just as much (if not more) of our daily lives.
Therefore it is important for us to understand the evolution of computers to understand where we may be heading in our relationship with computers.
I would like to preface that the following articles outlining the history of computers by saying this is in no way an exhaustive history of the origin of computers. Some major events have been glossed over while other meaningful contributions omitted entirely.
Whilst the thought of history for some may make the eyes automatically glisten over, I will try and make the following series as painless and exciting as possible. While I paint a story of linear progress of computation, this is hindsight bias in action. We like to create a story of history attributing certain importance to some events and not others when in reality as these events were unfolding (and continue to unfold) it was not always obvious what was a gigantic discovery. It is only now with some distance that we can appreciate past event. This means perhaps in ten years this recount will emphasis other features and neglect some of the stories today we find so foundational to computer’s creation.
With all this in mind let’s begin !!
The first computers
Since their inception computers have taken over human work by performing tedious, complex and repetitive tasks. Interestingly, t_he__ word computer initially described humans_!! Initially computers were humans (often women) who were able to perform complex mathematical computations — usually with pen and paper. Often teams would work on the same calculation independently to confirm the end results. It is interesting to note that initally when electronic computers were developed they were referred to as such — electronic computers. With time as electronic computers became more and more pervasive and powerful, it became the human computer that was deemed obsolete and inefficient. The electronic was dropped and now when we discuss computers we think of nothing else besides our gracefull and versalite electronic tools. It is important to keep computer’s mathematical origin in mind as we will see it only further emphasises the never imagined pervasiveness and uses of computers today.
Our story begins with the humble abacus, generally considered the first computer. When researching I was puzzled how an abacus could be considered a computer. Luckily my curiosity was settled by a quick Google search (thank you Google). Google was even able to suggest my search before I completed typing ‘Why is the abacus considered the first computer’! I ended up on trusty Quora where one users: Chrissie Nysen put things simply-“Because it is used to compute things.” Though estimates vary, the abacus is thought to originate in Babylon approximately 5000 years ago. The role of the abacus was to ease in simple mathematical calculations- addition, subtraction, division and multiplication. In this sense, we can consider the abacus as a simple calculator. As farming, produce and populations increased in size, the abacus allowed the educated to more easily manage logistics. After the abacus the first computer, computer’s evolution remained dormant for some time……

10 Writing steps to create a good project brief - Mobile app development
Developing a mobile application can often be more challenging than it seems at first glance. Whether you’re a developer, UI designer, project lead or CEO of a mobile-based startup, writing good project briefs prior to development is pivotal. According to Tech Jury, 87% of smartphone users spend time exclusively on mobile apps, with 18-24-year-olds spending 66% of total digital time on mobile apps. Of that, 89% of the time is spent on just 18 apps depending on individual users’ preferences, making proper app planning crucial for success.
Today’s audiences know what they want and don’t want in their mobile apps, encouraging teams to carefully write their project plans before they approach development. But how do you properly write a mobile app development brief without sacrificing your vision and staying within the initial budget? Why should you do so in the first place? Let’s discuss that and more in greater detail.
Why a Good Mobile App Project Brief Matters?
It’s worth discussing the significance of mobile app project briefs before we tackle the writing process itself. In practice, a project brief is used as a reference tool for developers to remain focused on the client’s deliverables. Approaching the development process without written and approved documentation can lead to drastic, last-minute changes, misunderstanding, as well as a loss of resources and brand reputation.
For example, developing a mobile app that filters restaurants based on food type, such as Happy Cow, means that developers should stay focused on it. Knowing that such and such features, UI elements, and API are necessary will help team members collaborate better in order to meet certain expectations. Whether you develop an app under your brand’s banner or outsource coding and design services to would-be clients, briefs can provide you with several benefits:
- Clarity on what your mobile app project “is” and “isn’t” early in development
- Point of reference for developers, project leads, and clients throughout the cycle
- Smart allocation of available time and resources based on objective development criteria
- Streamlined project data storage for further app updates and iterations
Writing Steps to Create a Good Mobile App Project Brief
1. Establish the “You” Behind the App
Depending on how “open” your project is to the public, you will want to write a detailed section about who the developers are. Elements such as company name, address, project lead, project title, as well as contact information, should be included in this introductory segment. Regardless of whether you build an in-house app or outsource developers to a client, this section is used for easy document storage and access.

50+ Useful Kubernetes Tools for 2020 - Part 2
Introduction
Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.
According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.
And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

History MCQs to Test Your History Knowledge
The beginning of the medieval period is ordinarily taken to be the moderate breakdown of the Gupta Empire from around 480 to 550, closure the “old style” period, just as “antiquated India”, albeit both these terms might be utilized for periods with broadly various dates, particularly in specific fields, for example, the historical backdrop of workmanship or religion. At any rate in northern India, there was no bigger state until maybe the Delhi Sultanate, or unquestionably the Mughal Empire. By 1413, the Tughlaq dynasty completely declined and the neighboring governor captured Delhi and this led to the start of the Sayyid Dynasty. In 1398, Timur attacked India and ransacked Indian riches. While returning back, he named Khizr Khan as the legislative head of Delhi.

AWS Bottlerocket vs. Google Container-Optimized OS: Which Should You Use and When
What’s the difference between popular Container-Centric OS choices, Google’s Container-Optimized OS, and AWS’s Bottlerocket? The concepts underlying containers have been around for many years. Container technologies like Docker, Kubernetes, and an entire ecosystem of products, as well as best practices, have emerged in the last few years. This has enabled different kinds of applications to be containerized.
Web service providers like Amazon AWS and Google are giving a further boost to container innovation, for enterprises to adopt and use containers at scale. This will help them to reap the benefits containers bring, including increased portability and greater efficiency.
Linux-based OS, AWS Bottlerocket is a new option, designed for running containers on virtual machines (VMs) or bare-metal hosts. In this article, you will learn the core uses and differences between the two open-source OS.
**AWS Bottlerocket **
It is an open-source, stripped-down Linux distribution that’s similar to projects like Google’s Container-Optimized OS. This single-step update process helps reduce management overhead.
_It makes OS updates easy to automate using container orchestration services such as Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS). _
**Google Container-Optimized OS **
It’s an OS image for Google Compute Engine VMs that’s optimized for running Docker containers. It allows you to bring up your Docker containers on Google Cloud Platform securely, and quickly. It is based on the open-source Chromium OS project and is maintained by Google.
But before diving into the core differences, let us give you a basic overview of containers, VMs, and container-optimized OS, and its underlying challenges to better understand the differences.
If you are already aware of all the underlying processes of containers, then you can skip to the main differences for AWS Bottlerocket vs Google Container-Optimized OS.
