A container is a process running with its own cgroup for resource limits and namespaces for process ID (PID), user ID (UID), mount, Inter-Process Communication (IPC), network, environment variable, etc. Through these configurations, the container process sees itself as isolated.

Let's talk about software development prioritization as well as the development cycle.

Etcd is a distributed key-value store that keeps the single source of truth for all configuration data and cluster state for a Kubernetes cluster. All Kubernetes objects like pods, deployments, and services, are stored in etcd.

Git was created as a code version management tool.

Go is a statically typed, compiled programming language. It has fast compilation and concurrency support via goroutines and channels. It uses a garbage collector to manage the heap memory.

JavaScript was created as a browser-only language to integrate with HTML/CSS, but nowadays it is used on various devices.

Kubernetes is a container orchestration engine for containerized application management and provides features like high availability, complex auto-scaling, automatic rollout and rollback, custom scheduling, and service mesh.

Learning coding is not easy, but here are some steps we can follow to boost our efficiency.

Linux is a free and open source Operating System (OS). It is the dominating OS on servers nowadays.

Markdown is a simple way to format text. Here I documented some best practices I found in the Google Markdown style guide.

Since the creation of computer network, people have gradually developed different set of rules for communication, and these are the network protocols.

PostgreSQL is an open-source relational database.

We have a business idea, and that's super cool! Now let's think about how to turn it into a product. Here are some steps that may give us some guidance.

We use programming languages to talk to computers, but how does it work? Here we discuss a few concepts about programming languages including types, syntax, and execution flow.

Rust is a system language that uses an ownership and borrowing system enforced at compile time to ensure memory safety without needing a garbage collector.

Software security measures are essential to prevent malicious actions.

Here we discuss the monolithic architecture, which is a tightly-coupled software running on a single physical server or Virtual Machine (VM) that handles the end-to-end workflow. Then we talk about the microservice architecture, which consists of many services running independently on different servers and connected via a network.

Ok, we want to build a software system for example a web application, but where should we start? Well, let's first think about the functional and non-functional requirements of our product. This gives us a list of questions to answer.

Transport Layer Security (TLS), is a popular protocol for secure data transmission between client and server. It is derived from a deprecated protocol called Secure Socket Layer (SSL).

Visual Studio Code (VSCode) is a lightweight Integrated Development Environment (IDE) that can become super powerful with extensions and plugins installed.

Zola is a static site generator (SSG) written in Rust and uses the Tera template engine. Zola uses pulldown-cmark to parse content written in CommonMark specification of Markdown. Zola prioritizes ease of use, super fast build, simple templating, and is suitable for minimalistic and fast dev blog.
