The idea of blockchain itself may sound complicated, but the premise is simple. Blockchain is a zero-trust, fully decentralized peer-to-peer data storage system that spreads verified information across participants in the chain, referred to as nodes. Blockchain stores this information in blocks that are chained together. As new data arrives, it is recorded into a block. Once a block has been filled with information, it is linked to the previous block. This process allows the data to be bound together in sequential and chronological order. 

What is KubeKey?

KubeKey is the newest Kubernetes installer for KubeSphere. KubeSphere is a distributed OS management system for cloud-native applications using Kubernetes as its kernel.

Introduction

In this second tutorial on server load, we outline the steps that should be taken when investigating where server load originates and what may be causing your server to become overloaded. As noted in Part 1 of our series, excessive use of any apps or services can typically cause load issues. Here are the four main areas of concern:

Introduction

In this two-part series, we outline the steps to take when investigating where server load originates or causing your server to become overloaded. When running a server that hosts multiple websites, high load issues often crop up. To find out how and why this occurs, read on. 

What is a Python Function? 

In this tutorial, we discuss one of the most useful attributes of Python: the function. Python functions are considered “First Class” objects. A First Class object can be assigned to variables, stored in data structures, passed as arguments to other functions, or even return values from other functions. Other examples of First Class objects in Python are integers, strings, and dictionaries.

What is a Port? 

First, let’s define what a port is. According to the IEFT, a port is: 

What is Telepresence?

Initially developed by Datawire, Telepresence is a new open-source tool supported by the CNCF (Cloud Native Computing Foundation). It allows developers to run local software while connected to a remote Kubernetes cluster. The application uses a two-way network proxy to simulate TCP connections, environmental variables, and other volumes of services as local processes. This link allows for remote work to be accomplished while seemingly local to the cluster via the proxied connection. 

What is ArangoDB?

ArangoDB is a high availability and scalable multi-model NoSQL database that natively works with graphs and documents and includes a full-text search. It is a free, open-source software developed and maintained by ArangoDB GmbH. The system supports three different data models with one database core and includes a unified query language called AQL (ArangoDB Query Language). This query language is declarative and allows the combination of different data access patterns in a single query. The software can be implemented on multiple systems, including Windows, macOS, Linux, Kubernetes, Docker, and on our Managed Cloud Servers. It has a strong community support base on GitHub, StackOverflow, Google Groups, and Slack.

What is Tmpmail?

Tmpmail is a utility written in bash that allows a user to create and use a temporary email address for receiving emails from the command-line. Underneath the covers, the bash script uses 1secmail’s API to receive the emails. By default, email addresses are created at random unless a specific email address follows the --generate flag.
