Payilagam — Thu, 21 May 2026 12:11:07 +0000

Marketing is the practice of identifying and satisfying customer needs. This is a particularly important task in the business context, as successful marketing efforts can drive leads and conversions. [To Be Discussed] [TBD]

Digital marketing, or online marketing, is the practice of promoting brands, products, or services through digital channels. It uses the internet and various online platforms to reach customers, boost brand visibility, and support business growth.

For example, when you see an advertisement while watching a YouTube video, that is digital marketing in action. These ads are a form of video marketing, a powerful strategy used by businesses to reach potential customers through engaging and targeted video content. Such advertisements can be tailored to the viewer's interests and behavior, making them a highly effective component of a comprehensive digital marketing strategy.

HTML (HyperText Markup Language) is the standard markup language used to create and structure web pages.

It defines the layout of a webpage using elements and tags[TBD], allowing for the display of text, images, links, and multimedia content.

As the foundation of nearly all websites, HTML is used in over 95% of all web pages today, making it an essential part of modern web development.

What about Remaining 5%:

Non-traditional web content such as:
PDFs opened directly in browsers
Browser-based games using canvas/WebGL
Embedded systems or kiosk interfaces
Raw XML or plain-text responses
Temporary or broken pages where no valid HTML is served.
Experimental technologies or closed environments.

git basics

Payilagam — Sat, 15 Nov 2025 08:25:38 +0000

Today, I learnt git in payilagam. git means Version Control System

Git is a free and open source distributed[To Be Discussed] version control system designed to handle everything from small to very large projects with speed and efficiency.

Let’s use your resume as an example. You’ve probably had several iterations of your resume over the course of your career. On your computer, you probably have separate files labeled resume, resumev2, resumev4, etc. But with version control, you can keep just one main resume file because the version control system (Git) tracks all the changes for you. So, you can have one file where you’re able to see its history, previous versions, and all the changes you’ve made over time.

What is version control?
Version control enables you to track changes to a software's source code. Thus, a software's delivered version consists of a set of specific versions of each of its components and source code files. For example, an icon might have only been changed twice, while a code file might have undergone several dozen changes over time.
