LEARN TECHNICAL BLOGGING DEEP DIVE

In the software industry, code is currency, but communication is leverage. A great engineer who can't explain their work is limited to the impact of their own two hands. A great engineer who *can* write scales their impact to thousands of developers.

Learn Technical Blogging: From Zero to Industry Voice

Goal: Master the art and engineering of technical blogging—from building your own high-performance platform and automating distribution to crafting articles that explain complex topics clearly, rank on search engines, and build a lasting personal brand.


Why Technical Blogging Matters

In the software industry, “code is currency, but communication is leverage.” A great engineer who can’t explain their work is limited to the impact of their own two hands. A great engineer who can write scales their impact to thousands of developers.

Technical blogging is not just about “writing posts.” It is a discipline that combines:

  1. System Engineering: Building high-performance, accessible content delivery systems.
  2. Pedagogy: The science of teaching complex topics effectively.
  3. Distribution Strategy: SEO, newsletters, and cross-posting to reach the right audience.

Historical figures like Joel Spolsky, Jeff Atwood (Coding Horror), and Julia Evans didn’t just write; they defined how we think about software. This path will give you the tools to join them.


Core Concept Analysis

1. The Static vs. Dynamic Paradigm

Most technical blogs today are Static Site Generators (SSGs), not dynamic databases like WordPress. Understanding why is key.

Dynamic Site (e.g., WordPress)         Static Site (e.g., Hugo/Jekyll)
------------------------------         -------------------------------
       User Request                           Developer "Builds"
            ↓                                      ↓
    [Web Server (Nginx)]                   [SSG Engine]
            ↓                                      ↓
    [PHP Interpreter]  <--[DB Query]       [HTML/CSS Files]
            ↓          -->--[Data]               ↓
     [HTML Generated]                      [Upload to CDN]
            ↓                                      ↓
      User Response                          User Request
                                                   ↓
                                            [CDN Edge Node]
                                                   ↓
                                             User Response

Why this matters: Speed and Security. There is no database to hack and no server processing time on request.

2. The Content Pipeline (Markdown to DOM)

Technical writing lives in Markdown, but the browser speaks DOM. The transformation pipeline is where the magic (and the bugs) happens.

[source.md]
   ↓
[Parser] (e.g., remark, goldmark)
   ↓
[AST] (Abstract Syntax Tree)
   ↓
[Transformers] (Syntax highlighting, Table of Contents, Auto-linking)
   ↓
[Renderer]
   ↓
[index.html]

Why this matters: To add features like “Copy Code” buttons or interactive graphs, you don’t hack the HTML; you write plugins for the AST transformation step.

3. The “Distribution Graph”

Writing is only 50% of the work. The rest is ensuring the content can be found and consumed.

       [Your Canonical Blog]
           /      |      \
        (RSS)   (JSON)  (Meta Tags)
          ↓       ↓        ↓
    [Aggregators] [API]  [Social Cards]
   (Daily.dev)   (Apps)  (Twitter/LinkedIn)

Why this matters: A blog without proper metadata (OpenGraph, JSON-LD, RSS) is invisible to the machines that govern the internet (Google, Social Media bots).


Concept Summary Table

Concept Cluster What You Need to Internalize
SSG Architecture Build-time vs. Run-time. HTML is generated once on your machine/CI, not on the server.
Content as Code Treat posts like code: Version control (Git), linting, automated testing, and CI/CD pipelines.
The DOM & AST Content is data. You manipulate the structure (AST) before it becomes the view (HTML).
Technical SEO Google is a robot. You must speak its language (Sitemaps, Schema.org, Canonical URLs) to be heard.
Performance (CWV) Speed is a feature. Core Web Vitals (LCP, CLS, INP) directly impact your ranking and user retention.

Project List

Projects are ordered from fundamental understanding to advanced platform engineering.


Project 1: The “No-Magic” Static Site

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: HTML/CSS
  • Alternative Programming Languages: N/A
  • Coolness Level: Level 2: Practical but Forgettable
  • Business Potential: 1. The “Resume Gold”
  • Difficulty: Level 1: Beginner
  • Knowledge Area: Web Fundamentals
  • Software or Tool: Text Editor, Browser
  • Main Book: “HTML & CSS: Design and Build Websites” by Jon Duckett

What you’ll build: A multi-page technical blog (Home, Post, About) written entirely in raw HTML and CSS, without any frameworks, generators, or JavaScript.

Why it teaches Technical Blogging: Before you use tools that generate HTML, you must understand what “perfect” HTML looks like. You will manually implement semantic tags, meta tags, and OpenGraph data, feeling the pain that SSGs solve.

Core challenges you’ll face:

  • Semantic Structure: Using <article>, <header>, <nav> correctly (maps to Accessibility/SEO).
  • Meta Data Management: Manually adding <meta property="og:image"> to every page (maps to Social Discovery).
  • Code Highlighting: Trying to style code blocks <pre><code> without a library (maps to Content Rendering).

Key Concepts:

  • Semantic HTML: MDN Web Docs - HTML Basics
  • OpenGraph Protocol: ogp.me
  • Critical CSS: web.dev - Extract Critical CSS

Difficulty: Beginner Time estimate: Weekend Prerequisites: Basic understanding of HTML tags.


Real World Outcome

You’ll have a folder of .html files that loads instantly in any browser and looks good when shared on Twitter.

Example Output:

<!-- You will manually write this for every post -->
<article>
  <h1>How Pointers Work in C</h1>
  <time datetime="2024-03-15">March 15, 2024</time>
  <p>Memory is just a giant array...</p>
</article>

When you paste the file path into a “Social Card Previewer”, you will see your custom image and description because you manually added the tags.

The Core Question You’re Answering

“What actually gets sent to the user’s browser?”

Before you write any automated code, sit with this question. Tools like React or Hugo abstract the DOM away. This project forces you to touch the raw material of the web.

Concepts You Must Understand First

  1. Semantic HTML
    • Why use <article> instead of <div>?
    • Reference: MDN Semantic HTML
  2. The Box Model
    • How do margins and padding affect readability?
    • Reference: MDN Box Model

Questions to Guide Your Design

  1. Typography: How many characters per line (measure) is optimal for reading? (Hint: 60-75).
  2. SEO: What is the difference between <title> and <h1>?

Thinking Exercise

The “Share” Simulation

Before coding, draw on paper what happens when you share a link on Slack.

  • Slack crawler visits URL -> Finds <head> -> Looks for og:title, og:image.
  • Question: What happens if og:image is missing? What does Slack display?

The Interview Questions They’ll Ask

  1. “Why is semantic HTML important for a technical blog?”
  2. “Explain the difference between display: none and visibility: hidden and how screen readers treat them.”
  3. “What are Core Web Vitals and how does raw HTML help achieve high scores?”

Hints in Layers

Hint 1: Focus on typography first. A blog is 90% text. Use a system font stack for speed. Hint 2: Use verify.seo or similar tools to check your meta tags locally. Hint 3: Don’t use classes for everything. Style the tags (p, h2) directly for a clean base stylesheet.

Project 2: The Markdown-to-HTML Compiler (Your Own SSG)

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: JavaScript (Node.js)
  • Alternative Programming Languages: Python, Go, Rust
  • Coolness Level: Level 3: Genuinely Clever
  • Business Potential: 2. The “Micro-SaaS” (if you add niche features)
  • Difficulty: Level 2: Intermediate
  • Knowledge Area: Parsers & File I/O
  • Software or Tool: remark, unified, or markdown-it
  • Main Book: “Crafting Interpreters” (Conceptually relevant)

What you’ll build: A CLI tool that reads a folder of Markdown files, parses the “Frontmatter” (metadata), converts the content to HTML, wraps it in a layout template, and outputs a deployable website.

Why it teaches Technical Blogging: You are building the engine that powers 90% of developer blogs (Jekyll, Hugo, Next.js). You will understand exactly how your words are transformed into code.

Core challenges you’ll face:

  • Frontmatter Parsing: Extracting YAML metadata (title, date) from the top of the file (maps to Metadata Management).
  • Templating: Injecting the content into a consistent header/footer layout (maps to DRY Principle).
  • Syntax Highlighting: Detecting code blocks and applying classes for coloring (maps to AST Transformation).

Key Concepts:

  • Abstract Syntax Trees (AST): Unified.js documentation
  • File System API: Node.js fs module
  • Templating Engines: Handlebars / EJS / Jinja2

Difficulty: Intermediate Time estimate: 1 Week Prerequisites: Basic JavaScript/Node.js, filesystem operations.


Real World Outcome

You’ll run a command like node build.js and watch your src/ folder of markdown files magically turn into a public/ folder of full HTML pages.

Example Output:

$ node build.js
[INFO] Found 3 posts.
[INFO] Parsing "hello-world.md"...
[INFO] Generating "public/hello-world.html"...
[SUCCESS] Build complete in 45ms.

The Core Question You’re Answering

“How do we separate content (Markdown) from presentation (HTML)?”

Before coding, think about why we don’t just write HTML. Markdown is for humans; HTML is for browsers. This tool bridges that gap.

Concepts You Must Understand First

  1. YAML Frontmatter
    • What is it? (The --- block at the top).
    • Reference: Jekyll Front Matter docs.
  2. Regular Expressions
    • How do you find the separation between YAML and content?

Questions to Guide Your Design

  1. Architecture: Will you process files one by one, or load them all into memory first? (Memory vs. Speed).
  2. Permalinks: How will you decide the output URL? (Filename? Date-based? Slug in frontmatter?).

Thinking Exercise

The AST Trace

Take this markdown:

# Hello
*World*

Trace how a parser sees it:

  1. Heading(depth: 1, text: “Hello”)
  2. Emphasis(text: “World”)

Question: How do you turn that Heading node into <h1>Hello</h1>?

The Interview Questions They’ll Ask

  1. “What is an Abstract Syntax Tree and how is it used in static site generation?”
  2. “How would you implement a ‘Related Posts’ feature in your SSG?”
  3. “What are the security implications of rendering user-generated Markdown?” (XSS).

Hints in Layers

Hint 1: Use a library like gray-matter to separate the frontmatter from the body. Hint 2: Don’t write a markdown parser from scratch. Use marked or remark. Focus on the glue code. Hint 3: Create a simple HTML string template: const layout = (body) => `<html><body>${body}</body></html>`.

Project 3: The “Explain It Like I’m 5” (Content Strategy)

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: English (Writing)
  • Alternative Programming Languages: N/A
  • Coolness Level: Level 1: Pure Corporate Snoozefest (but vital)
  • Business Potential: 5. The “Industry Disruptor” (Great writing builds empires)
  • Difficulty: Level 5: Master (Writing simply is incredibly hard)
  • Knowledge Area: Technical Communication
  • Software or Tool: Hemingway App, Google Docs
  • Main Book: “On Writing Well” by William Zinsser

What you’ll build: A rigorous 3-part article series explaining a complex topic (e.g., DNS, Docker, OAuth) using three specific layers of abstraction: The ELI5, The Engineer, and The Deep Dive.

Why it teaches Technical Blogging: The code is the easy part. The hard part is empathy. This project forces you to structure information for different audiences, which is the hallmark of top-tier technical blogs.

Core challenges you’ll face:

  • The Curse of Knowledge: Forgetting what it’s like not to know something (maps to Empathy).
  • Visual Thinking: Creating ASCII diagrams or charts to replace paragraphs of text (maps to Visual Communication).
  • Structure: Hooking the reader in the first 2 paragraphs (maps to Engagement).

Key Concepts:

  • The Pyramid Principle: Barbara Minto
  • Active Voice: Strunk & White
  • Cognitive Load: Psychology of Learning

Difficulty: Advanced (Writing is harder than coding) Time estimate: 2 Weeks Prerequisites: Deep knowledge of ONE technical topic.


Real World Outcome

You will publish three distinct pieces of content:

  1. “How the Internet Works” (Analogy-heavy, for beginners).
  2. “Implementing a TCP Handshake” (Code-heavy, for juniors).
  3. “Optimizing TCP Window Sizes” (Data-heavy, for experts).

Example Output:

  • Analogy: “Think of TCP like a certified mail receipt…”
  • Code: int sock = socket(AF_INET, SOCK_STREAM, 0);
  • Deep Dive: “In Linux kernel 5.4, the congestion window defaults to…”

The Core Question You’re Answering

“Who am I writing for, and what problem am I solving for them?”

Before writing, define the Avatar. Are they a stressed junior dev? A CTO? A hobbyist? You cannot write for everyone at once.

Concepts You Must Understand First

  1. The F-Pattern Reading
    • People scan content. How do headers stop them?
    • Reference: Nielsen Norman Group

Questions to Guide Your Design

  1. Analogy Check: Does your analogy break down? (e.g., “Electricity is like water” fails when you talk about inductance).
  2. Scanability: Can I understand the article just by reading the headers?

Thinking Exercise

The “Bar Test”

Imagine explaining your topic to a friend at a bar.

  • You wouldn’t say “The accumulation of TCP segments…”
  • You’d say “It waits for a bunch of packets to arrive…”
  • Exercise: Record yourself explaining it out loud. Transcribe that. That’s your first draft.

The Interview Questions They’ll Ask

  1. “Explain a complex technical concept to me as if I were a non-technical stakeholder.” (Standard interview question).
  2. “How do you decide what to include and what to leave out in documentation?”

Hints in Layers

Hint 1: Write the headers first. This is your skeleton. Hint 2: Use the “Hemingway App” to highlight complex sentences. Aim for Grade 6-8 readability. Hint 3: Every paragraph must have one single idea. If it has two, split it.

Project 4: The Performance Auditor & Optimizer

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: JavaScript
  • Alternative Programming Languages: Shell Scripting
  • Coolness Level: Level 3: Genuinely Clever
  • Business Potential: 3. Service & Support (Site speed consulting)
  • Difficulty: Level 3: Advanced
  • Knowledge Area: Web Performance
  • Software or Tool: Lighthouse CI, WebPageTest
  • Main Book: “High Performance Browser Networking”

What you’ll build: A heavily optimized version of your blog that scores 100/100 on Core Web Vitals, even on 3G networks. You will implement image optimization pipelines, critical CSS inlining, and font subsetting.

Why it teaches Technical Blogging: Readers bounce if your site takes >3 seconds to load. Google penalizes you. This teaches you the engineering side of content delivery.

Core challenges you’ll face:

  • Cumulative Layout Shift (CLS): preventing images from pushing text around (maps to CSS Aspect Ratios).
  • Largest Contentful Paint (LCP): getting that hero image to load instantly (maps to Image Formats AVIF/WebP).
  • Font Loading Strategies: avoiding “Flash of Invisible Text” (maps to Font Display Swap).

Key Concepts:

  • Critical Rendering Path: MDN Performance
  • Resource Hints (preload, preconnect): w3c specs
  • Image Compression Algorithms: MozJPEG / AVIF

Difficulty: Advanced Time estimate: 1 Week Prerequisites: A working blog, Chrome DevTools knowledge.


Real World Outcome

A “perfect” Lighthouse report and a blog that loads visibly instantly.

Example Output:

Lighthouse Report:
  Performance: 100
  Accessibility: 100
  Best Practices: 100
  SEO: 100

First Contentful Paint: 0.4s
Interactive: 0.6s
Total Blocking Time: 0ms

The Core Question You’re Answering

“What is the minimum number of bytes required to paint the pixels the user cares about?”

Concepts You Must Understand First

  1. The Waterfall
    • How browsers request assets. CSS blocks rendering. JS blocks parsing.
    • Reference: Chrome DevTools Network Tab

Questions to Guide Your Design

  1. Images: Do you really need that 4MB GIF? Can it be an MP4 video (smaller)?
  2. Fonts: Do you need the “Bold Italic” weight if you never use it?

Thinking Exercise

The 14KB Challenge

TCP slow start usually sends ~14KB in the first round trip.

  • Exercise: Can you fit your HTML + Critical CSS + HEAD into the first 14KB?
  • If yes, your site renders in one network round trip.

The Interview Questions They’ll Ask

  1. “What are the Core Web Vitals and why do they matter?”
  2. “How do you optimize a website for high-latency mobile networks?”
  3. “Explain the difference between defer and async on script tags.”

Hints in Layers

Hint 1: Convert all images to WebP. Hint 2: Inline your main CSS in the <head> style tag for the homepage. Hint 3: Self-host your fonts. Google Fonts adds a DNS lookup and connection overhead.

Project 5: The SEO Analyzer Tool

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: Python
  • Alternative Programming Languages: JavaScript (Puppeteer), Go
  • Coolness Level: Level 3: Genuinely Clever
  • Business Potential: 3. Service & Support (Agency Tool)
  • Difficulty: Level 2: Intermediate
  • Knowledge Area: DOM Parsing & HTTP
  • Software or Tool: Beautiful Soup, Requests
  • Main Book: “Web Scraping with Python”

What you’ll build: A CLI tool that crawls your local build folder (or live site), checks every page for critical SEO failures (missing descriptions, broken internal links, images without alt text), and generates a “Health Report.”

Why it teaches Technical Blogging: SEO isn’t magic; it’s compliance. If you forget a <link rel="canonical">, Google ignores you. This project automates the discipline required for professional publishing.

Core challenges you’ll face:

  • Recursive Crawling: Following internal links without getting stuck in loops (maps to Graph Traversal).
  • DOM Inspection: efficiently querying thousands of HTML files for specific tags (maps to Parsing).
  • Status Code Validation: Checking external links to ensure they aren’t 404s (maps to Network Reliability).

Key Concepts:

  • HTTP Status Codes: RFC 7231
  • Sitemaps (XML): sitemaps.org Protocol
  • Robots.txt: Robots Exclusion Standard

Difficulty: Intermediate Time estimate: Weekend Prerequisites: Python basics, HTML structure.


Real World Outcome

You run python check_seo.py ./public and get a pass/fail report before you deploy.

Example Output:

[FAIL] /posts/docker-tutorial.html
   - Missing meta description
   - Broken link: http://example.com/dead-link (404)
   - Image img/docker-logo.png missing 'alt' attribute

[PASS] /posts/react-guide.html

Score: 85/100. Deployment aborted.

The Core Question You’re Answering

“Is my content machine-readable?”

Concepts You Must Understand First

  1. Canonical URLs
    • Why does Google punish duplicate content?
    • Reference: Google Search Central

Questions to Guide Your Design

  1. Performance: Will you check links sequentially or concurrently (threads/async)?
  2. Strictness: Should a missing og:image break the build or just warn?

Thinking Exercise

The Crawler Logic

Draw a flowchart:

  1. Start at index.html.
  2. Find all <a> tags.
  3. If link starts with / (internal), add to queue.
  4. If link starts with http (external), just HEAD request it.
  5. Question: How do you prevent visiting index.html twice? (Visited Set).

The Interview Questions They’ll Ask

  1. “How would you design a web crawler to respect robots.txt?”
  2. “What is the difference between a 301 and 302 redirect for SEO?”

Hints in Layers

Hint 1: Use BeautifulSoup to parse the HTML. Hint 2: Use a Python set() to keep track of visited URLs. Hint 3: For external links, use requests.head() instead of .get() to save bandwidth.

Project 6: The “Interactive” Blog Post (MDX Component)

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: React / JavaScript
  • Alternative Programming Languages: Vue, Svelte
  • Coolness Level: Level 5: Pure Magic (Super Cool)
  • Business Potential: 5. Industry Disruptor (Interactive content is the future)
  • Difficulty: Level 4: Expert
  • Knowledge Area: Frontend Frameworks & Hydration
  • Software or Tool: MDX, Gatsby/Next.js/Astro
  • Main Book: “Full Stack React” (for component patterns)

What you’ll build: A blog post that contains a living, breathing React component inside the Markdown. For example, a “Sorting Algorithm” post where the user can click “Step” to see the array swap elements in real-time.

Why it teaches Technical Blogging: The best technical blogs (Julia Evans, Josh Comeau) don’t just tell you; they show you. This requires mastering the “Island Architecture” or partial hydration.

Core challenges you’ll face:

  • Hydration: Making static HTML “wake up” into an interactive app on the client (maps to Client-Side Bootstrapping).
  • Component Isolation: Ensuring the styles of your interactive graph don’t break the rest of the blog (maps to Shadow DOM / CSS Modules).
  • State Management: Keeping the blog post text in sync with the interactive visual (maps to React Context).

Key Concepts:

  • Islands Architecture: Astro Documentation
  • MDX (Markdown + JSX): mdxjs.com
  • Client-Side Hydration: React Docs

Difficulty: Expert Time estimate: 2 Weeks Prerequisites: Strong React/JS knowledge.


Real World Outcome

A blog post about “Compound Interest” where the user drags a slider and the graph updates instantly, embedded right in the text.

Example Output:

“As you increase the interest rate, the curve steepens. Try it:” [ Slider: 5% ] -> [ Graph Curves Up ] “Notice how the doubling time decreases…”

The Core Question You’re Answering

“Why explain with text what I can explain with a toy?”

Concepts You Must Understand First

  1. Hydration Mismatch
    • What happens if the server renders “0” but the client renders “1”?
    • Reference: React Docs - Hydration Errors

Questions to Guide Your Design

  1. Performance: Does loading this one graph require loading 2MB of React? (Check Astro or Preact).
  2. Fallback: What does the user see if JavaScript is disabled?

Thinking Exercise

The Component Boundary

Draw the DOM tree:

<body>
  <article>
    <p>Static Text</p>
    <div id="interactive-root"></div> <!-- React mounts here -->
    <p>Static Text</p>
  </article>
</body>

Question: How do you pass data from the Markdown (e.g., <Counter start={5} />) to the React component?

The Interview Questions They’ll Ask

  1. “Explain the concept of ‘Partial Hydration’ or ‘Islands Architecture’.”
  2. “What are the performance costs of using React for a content-heavy site?”

Hints in Layers

Hint 1: Use Astro. It is built specifically for this “content-first, JS-second” approach. Hint 2: If using Next.js, look into next-mdx-remote. Hint 3: Start simple: A button that increments a counter inside a markdown file.

Project 7: The Newsletter Pipeline (RSS-to-Email)

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: TypeScript (Serverless Functions)
  • Alternative Programming Languages: Python
  • Coolness Level: Level 2: Practical
  • Business Potential: 4. Open Core (Email marketing platform)
  • Difficulty: Level 3: Advanced
  • Knowledge Area: APIs & Email Protocols
  • Software or Tool: AWS Lambda / Vercel Functions, SendGrid/Mailgun API
  • Main Book: “Serverless Architectures on AWS”

What you’ll build: An automated system that watches your blog’s RSS feed. When a new post appears, it generates an HTML email template, inlines the CSS (email is old-school), and sends it to your subscribers via an API.

Why it teaches Technical Blogging: You don’t own your Twitter followers. You own your email list. This project builds the critical infrastructure for “audience ownership” without paying for Mailchimp.

Core challenges you’ll face:

  • State Tracking: Remembering which posts have already been sent (maps to Database/Caching).
  • HTML for Email: Coding like it’s 1999 because Outlook doesn’t support modern CSS (maps to Legacy Support).
  • Deliverability: Setting up DKIM, SPF, and DMARC so you don’t hit spam folders (maps to DNS & Security).

Key Concepts:

  • RSS (Rich Site Summary): XML Standards
  • SMTP & APIs: Email Transmission
  • Cron Jobs: Scheduled Tasks

Difficulty: Advanced Time estimate: 1 Week Prerequisites: Basic API usage, DNS knowledge.


Real World Outcome

You publish a post. 15 minutes later, your phone buzzes with an email: “New Post: [Title]”. You didn’t touch anything.

Example Output:

// Log from your Lambda function
[INFO] Checking RSS feed...
[INFO] Found new item: "guid-12345"
[INFO] Generating template...
[INFO] Sent to 450 subscribers via SendGrid.
[INFO] Updated database: last_sent = "guid-12345"

The Core Question You’re Answering

“How do I push content to users instead of waiting for them to pull it?”

Concepts You Must Understand First

  1. DKIM/SPF
    • Why does Gmail trust your email?
    • Reference: Postmark Guides

Questions to Guide Your Design

  1. Failure Mode: What happens if the email API fails halfway through the list? (Idempotency).
  2. Unsubscribe: You LEGALLY need a working unsubscribe link. How do you implement that?

Thinking Exercise

The “Table Layout”

Email clients hate divs. They love tables.

  • Exercise: Try to build a two-column layout using only <table>, <tr>, and <td>. That’s your email template.

The Interview Questions They’ll Ask

  1. “How do you handle ‘at-least-once’ delivery guarantees in a notification system?”
  2. “What are SPF, DKIM, and DMARC?”

Hints in Layers

Hint 1: Use mjml (a framework) to generate the email HTML. Don’t write raw table soup by hand. Hint 2: Store the “last sent GUID” in a simple JSON file on S3 or a Redis key. Hint 3: Use Vercel Cron Jobs to trigger the check every hour.

  • Main Programming Language: JavaScript (Node.js)
  • Alternative Programming Languages: Rust
  • Coolness Level: Level 4: Hardcore Tech Flex
  • Business Potential: 2. Micro-SaaS (Image generation API)
  • Difficulty: Level 3: Advanced
  • Knowledge Area: Graphics & Canvas
  • Software or Tool: Puppeteer / Playwright, Canvas API
  • Main Book: “Computer Graphics from Scratch” (Conceptually)

What you’ll build: A build-step script that takes the title, date, and tags of a blog post and programmatically draws a custom social media preview image (PNG) using a headless browser or canvas library.

Why it teaches Technical Blogging: Generic stock photos are boring. Custom branded images increase click-through rates on social media by 40%+. Doing it manually is slow; doing it with code is scalable.

Core challenges you’ll face:

  • Text Wrapping: Calculating how to break a long title into multiple lines on a canvas (maps to Graphics Algorithms).
  • Headless Rendering: Launching a hidden Chrome instance to take a “screenshot” of a component (maps to Browser Automation).
  • Performance: Generating 100 images shouldn’t take 10 minutes (maps to Caching/Concurrency).

Key Concepts:

  • Canvas API: MDN Canvas
  • Headless Browsers: Chrome DevTools Protocol
  • Buffer/Stream handling: Binary Data

Difficulty: Advanced Time estimate: Weekend Prerequisites: JS, Node.js.


Real World Outcome

Every post in your public/images/og/ folder has a corresponding my-post-title.png that looks professionally designed, with the correct title and reading time burned into the pixels.

Example Output:

$ node generate-og.js
[INFO] Generating image for "Understanding Async/Await"
[INFO] Drawing background...
[INFO] Rendering text "Understanding..." at (50, 100)
[INFO] Saved to public/og/async-await.png

The Core Question You’re Answering

“How do I make my content look premium automatically?”

Concepts You Must Understand First

  1. Coordinate Systems
    • (0,0) is top-left. Y grows downwards.
    • Reference: MDN Canvas Grid

Questions to Guide Your Design

  1. Method: Will you use HTML/CSS + Screenshot (easier) or pure Canvas drawing (faster) (Caution: font loading).
  2. Caching: If the title hasn’t changed, don’t regenerate the image.

Thinking Exercise

The Text Wrapper

Write a function in your head: wrapText(context, text, x, y, maxWidth, lineHeight)

  • It needs to measure the width of each word.
  • If line + word > maxWidth, move y down by lineHeight.

The Interview Questions They’ll Ask

  1. “When would you use Canvas vs. SVG vs. DOM for generating images?”
  2. “How do you debug a headless browser process that crashes in CI?”

Hints in Layers

Hint 1: Use satori (by Vercel). It converts HTML/CSS directly to SVG, which is much faster than Puppeteer. Hint 2: If using Puppeteer, reuse the browser instance. Launching Chrome for every image will kill your CPU. Hint 3: Design the “template” in HTML/CSS first, then just take screenshots of it.

  • Main Programming Language: JavaScript / TypeScript
  • Alternative Programming Languages: Python
  • Coolness Level: Level 4: Hardcore Tech Flex
  • Business Potential: 2. Micro-SaaS (Knowledge Management Tool)
  • Difficulty: Level 4: Expert
  • Knowledge Area: Graph Theory & Data Structures
  • Software or Tool: D3.js or Cytoscape.js
  • Main Book: “Introduction to Graph Theory”

What you’ll build: A “bi-directional linking” system. When you mention [[Another Post]], it links forward and the target post shows a “Backlinks” section. Plus, a visual force-directed graph showing how all your posts connect.

Why it teaches Technical Blogging: Blogs are usually linear (time-based). Digital Gardens are spatial (topic-based). This transforms your blog from a “log” into a “wiki,” increasing user retention by helping them fall down rabbit holes.

Core challenges you’ll face:

  • Parsing Wiki-Links: Detecting [[...]] syntax and resolving it to a file path (maps to Compiler Lexing).
  • Building the Adjacency List: constructing the graph data structure of all pages (maps to Graph Algorithms).
  • Visualization: Rendering 100+ nodes in D3.js without it looking like a hairball (maps to Data Viz).

Key Concepts:

  • Graph Theory (Nodes/Edges): CS Fundamentals
  • Force-Directed Layouts: Physics Simulation
  • Wiki-Text Parsing: Regular Expressions

Difficulty: Expert Time estimate: 2 Weeks Prerequisites: Understanding of Recursion and Graph structures.


Real World Outcome

At the bottom of your “Docker” post, it says: “Linked to by: ‘Kubernetes Guide’ and ‘Linux Containers’”. On your /graph page, a floating interactive constellation of dots shows your knowledge map.

Example Output:

// graph.json
{
  "nodes": [{ "id": "docker.md" }, { "id": "k8s.md" }],
  "links": [{ "source": "k8s.md", "target": "docker.md" }]
}

The Core Question You’re Answering

“How is knowledge connected?”

Concepts You Must Understand First

  1. Adjacency Matrix vs. Adjacency List
    • Which is better for a sparse graph like a blog? (List).
    • Reference: Algorithms 4th Ed.

Questions to Guide Your Design

  1. Resolution: What happens if I type [[Docker]] but the file is named docker-guide.md? (Fuzzy matching).
  2. Context: Can you show a “snippet” of text surrounding the backlink?

Thinking Exercise

The Cycle Detector

  • Post A links to Post B.
  • Post B links to Post A.
  • Exercise: Write a function that detects this cycle. Does it matter for a blog? (Not really, but good to know).

The Interview Questions They’ll Ask

  1. “How would you store a graph in a SQL database vs. a Graph database?”
  2. “Explain how force-directed graph algorithms work.”

Hints in Layers

Hint 1: Use remark-wiki-link plugin if you are using Remark. Hint 2: Generate the graph.json at build time, not runtime. Hint 3: Use react-force-graph for the UI if D3 is too low-level.

Project 10: The Privacy-First Analytics Engine

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: Go / Rust
  • Alternative Programming Languages: Node.js
  • Coolness Level: Level 4: Hardcore Tech Flex
  • Business Potential: 3. Service & Support (GDPR Compliance)
  • Difficulty: Level 3: Advanced
  • Knowledge Area: Database Design & Privacy
  • Software or Tool: SQLite / ClickHouse
  • Main Book: “Designing Data-Intensive Applications”

What you’ll build: A minimal analytics server. It receives a POST /hit from your blog, hashes the IP with a daily salt (so it’s anonymized but unique for 24h), stores the count in SQLite, and serves a dashboard. No cookies. No GDPR banners needed.

Why it teaches Technical Blogging: You need to know if people are reading. Google Analytics is bloated and invasive. Building your own teaches you about data ingestion, write-heavy workloads, and privacy engineering.

Core challenges you’ll face:

  • Write Throughput: Handling concurrent requests without locking the DB (maps to Concurrency).
  • Anonymization: Ideally hashing user data so it cannot be reversed (maps to Cryptography).
  • Bot Filtering: Detecting if a request is a user or a crawler (maps to User Agent Parsing).

Key Concepts:

  • Log-Structured Merge-Trees: Database Storage
  • Bloom Filters: Probabilistic Data Structures
  • HyperLogLog: Cardinality Estimation

Difficulty: Advanced Time estimate: 1-2 Weeks Prerequisites: Backend API development.


Real World Outcome

A dashboard at analytics.yourblog.com showing: “150 Visitors Today”. No cookie banner on your site. The database stores: Hash(IP + Date + Salt), /post-url, User-Agent.

Example Output:

// The Anonymizer
salt := GetDailySalt() // Rotates every 24h
hash := sha256.Sum256([]byte(ip_address + salt))
// We store 'hash', we never store 'ip_address'

The Core Question You’re Answering

“How do I count people without spying on them?”

Concepts You Must Understand First

  1. GDPR & PECR
    • What is “Personal Data”? Is an IP address personal data? (Yes).
    • Reference: ICO Guidelines

Questions to Guide Your Design

  1. Session Tracking: If I don’t use cookies, how do I know if a user visits 2 pages? (The IP hash acts as a temporary session ID).
  2. Performance: Should you write to DB on every request or buffer them in memory?

Thinking Exercise

The Salt Rotation

If you use the same salt forever, the hash is permanent. If you rotate the salt every 24h, you can’t track returning users across days.

  • Decision: This is a trade-off. Privacy vs. Long-term metrics. Which do you choose?

The Interview Questions They’ll Ask

  1. “How would you design a system to count 1 million hits per second?” (Hint: HyperLogLog).
  2. “What is the difference between a Row-oriented and Column-oriented database?”

Hints in Layers

Hint 1: Use SQLite in WAL mode. It can handle surprisingly high concurrency. Hint 2: Filter out bots by checking the User-Agent string against a known list. Hint 3: Use a 1-pixel transparent GIF or navigator.sendBeacon for the tracking implementation.

Project 11: The Multi-Language Blog (i18n Architecture)

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: JavaScript / Configuration
  • Alternative Programming Languages: N/A
  • Coolness Level: Level 2: Practical
  • Business Potential: 3. Service (Localization is huge for enterprise)
  • Difficulty: Level 3: Advanced
  • Knowledge Area: System Architecture
  • Software or Tool: SSG i18n plugins
  • Main Book: “Global Software: From Machine Translation to Internationalization”

What you’ll build: A structure that supports /en/post-1 and /es/post-1. You will implement content fallback (if Spanish is missing, show English), UI translation (“Read More” vs “Leer Más”), and hreflang tags for SEO.

Why it teaches Technical Blogging: The web is global. Structuring a codebase to handle multiple languages is a classic architectural challenge involving routing, state, and content management.

Core challenges you’ll face:

  • Routing: Handling /es/ prefixes without duplicating layout code (maps to Middleware/Routing).
  • Content Sync: knowing which English posts haven’t been translated yet (maps to Content Auditing).
  • Date Formatting: MM/DD/YYYY vs DD/MM/YYYY (maps to Localization API).

Key Concepts:

  • i18n (Internationalization) vs l10n (Localization)
  • ISO 639-1 Codes: Standard Language Codes
  • Hreflang Headers: SEO for Languages

Difficulty: Advanced Time estimate: 1 Week Prerequisites: Familiarity with your SSG.


Real World Outcome

A dropdown in your navbar lets users switch languages. Google indexes both versions correctly because you have the right tags.

Example Output:

<link rel="alternate" hreflang="en" href="https://blog.com/en/hello" />
<link rel="alternate" hreflang="es" href="https://blog.com/es/hola" />

The Core Question You’re Answering

“How do I architect for variation?”

Concepts You Must Understand First

  1. Unicode & UTF-8
    • Why does 😊.length === 2?
    • Reference: The Absolute Minimum Every Software Developer Must Know About Unicode

Questions to Guide Your Design

  1. URL Structure: Subdomain (es.blog.com) vs Subdirectory (blog.com/es). (Subdirectory is usually better for SEO authority).
  2. UI Strings: Where do you store the translation for “Next Post”? (JSON dictionary).

Thinking Exercise

The Fallback Logic

  • User requests /es/advanced-topic.
  • You don’t have a Spanish translation.
  • Exercise: Do you 404? Do you redirect to English? Do you show English content on the Spanish URL with a warning? (The last one is usually best).

The Interview Questions They’ll Ask

  1. “Explain the difference between Intl.DateTimeFormat and moment.js.”
  2. “How does hreflang prevent duplicate content penalties?”

Hints in Layers

Hint 1: Organize content by file: post.en.md, post.es.md. Hint 2: Use Intl.RelativeTimeFormat for “5 minutes ago”. Hint 3: Don’t hardcode strings in your templates. Use a t('read_more') helper function.

Project 12: The Crossposting CLI (Syndication)

  • File: LEARN_TECHNICAL_BLOGGING_DEEP_DIVE.md
  • Main Programming Language: Python / TypeScript
  • Alternative Programming Languages: Go
  • Coolness Level: Level 3: Clever
  • Business Potential: 2. Micro-SaaS (Content Ops)
  • Difficulty: Level 2: Intermediate
  • Knowledge Area: APIs & OAuth
  • Software or Tool: Dev.to API, Hashnode API, Medium API
  • Main Book: “API Design Patterns”

What you’ll build: A CLI tool that takes your markdown file, detects the canonical URL, and pushes it to Dev.to, Hashnode, and Medium via their APIs, ensuring the “Canonical URL” is set correctly so you don’t destroy your SEO.

Why it teaches Technical Blogging: “Write Once, Publish Everywhere” (POSSE). You learn to interact with 3rd party APIs, handle authentication, and map your data format to theirs.

Core challenges you’ll face:

  • Format Conversion: Medium doesn’t support Markdown perfectly; you might need to convert to HTML first (maps to Data Transformation).
  • Canonical Safety: Critically ensuring the canonical_url field is sent, otherwise Google penalizes you for plagiarism (maps to SEO Safety).
  • Asset Uploading: Uploading your local images to their CDN and replacing the links (maps to Asset Management).

Key Concepts:

  • Canonical URLs: SEO
  • REST APIs: HTTP Methods
  • Markdown Flavors: CommonMark vs GFM

Difficulty: Intermediate Time estimate: Weekend Prerequisites: API Keys, JSON.


Real World Outcome

$ publish-cli ./posts/new-guide.md
[CHECK] Canonical URL present? Yes.
[UPLOAD] Uploading to Dev.to... Success (ID: 1234)
[UPLOAD] Uploading to Hashnode... Success (slug: new-guide)
[DONE] Published to 2 platforms.

The Core Question You’re Answering

“How do I leverage other people’s audiences without losing my own?”

Concepts You Must Understand First

  1. The Canonical Tag
    • It tells Google: “This version on Dev.to is just a copy. The original is on MyBlog.com.”

Questions to Guide Your Design

  1. Sync: If you update the local post, does running the tool again update the remote post or create a duplicate? (Need to store the remote IDs).
  2. Drafts: Should it publish as a ‘draft’ first so you can check formatting?

Thinking Exercise

The Image Problem

  • Local markdown: ![Image](./img/cat.png)
  • Remote API: Needs a public URL.
  • Logic: You need to upload ./img/cat.png to S3/Cloudinary first, get the URL https://cdn.com/cat.png, replace it in the markdown string, then send the markdown to Dev.to.

The Interview Questions They’ll Ask

  1. “How do you handle API rate limits when broadcasting content?”
  2. “What is the POSSE model (Publish Own Site, Syndicate Elsewhere)?”

Hints in Layers

Hint 1: Dev.to API is the easiest to start with. Hint 2: Use a frontmatter field devto_id to store the ID after the first publish, so you know to update it next time. Hint 3: Be careful with Medium. Their API is often deprecated or limited.

Recommendation

Where to Start?

  • If you are a Junior Dev: Start with Project 1 (No-Magic HTML). It is humble, but it prevents you from becoming a “Framework Developer” who doesn’t know what a generic <div> is. Then move to Project 3 (Writing) because communication will accelerate your career faster than code.
  • If you are a Senior Dev: Jump to Project 2 (Your Own SSG). You likely know how to write, but building the toolchain will give you total control. Then build Project 6 (Interactive Post) to distinguish yourself from the sea of Medium articles.
  • If you want to build a Business: Focus on Project 7 (Newsletter) and Project 12 (Crossposting). Distribution is your bottleneck, not code.

Final Overall Project: The “Sovereign Creator” Platform

Goal: Combine all previous projects into a single, unified Command Line Interface (CLI) and web dashboard that manages your entire digital presence—from drafting to analytics—owned 100% by you.

The Vision: You don’t log into WordPress. You don’t open Substack. You open your terminal.

Features:

  1. sovereign new "My Post": Scaffolds a post with frontmatter.
  2. sovereign draft: Starts a local server with Project 2 (SSG) and Project 6 (Interactive) support.
  3. sovereign audit: Runs Project 4 (Perf) and Project 5 (SEO) checks.
  4. sovereign publish:
    • Compiles HTML.
    • Generates OG Images (Project 8).
    • Deploys to AWS/Netlify.
    • Sends Email (Project 7).
    • Crossposts to Dev.to (Project 12).
  5. sovereign stats: Pulls data from your Project 10 analytics and displays a TUI (Text User Interface) graph in the terminal.

Why this is the ultimate test: It requires Full Stack mastery. You are building a Compiler (SSG), a Backend (Analytics/Email), a CLI (Rust/Go/Node), and a Frontend (The blog itself). It is a product that could genuinely be a startup, but you’re building it for yourself to prove you can.
