Technical Blog Writing

Write developer-focused technical blog posts via inference.sh CLI.

Quick Start

curl -fsSL https://cli.inference.sh | sh && infsh login

# Research topic depth
infsh app run exa/search --input '{
  "query": "building REST API Node.js best practices 2024 tutorial"
}'

# Generate header image
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1200px;height:630px;background:linear-gradient(135deg,#0f172a,#1e293b);display:flex;align-items:center;padding:60px;font-family:ui-monospace,monospace;color:white\"><div><p style=\"font-size:18px;color:#38bdf8;margin:0\">// engineering blog</p><h1 style=\"font-size:48px;margin:16px 0;font-weight:800;font-family:system-ui;line-height:1.2\">How We Reduced API Latency by 90% with Edge Caching</h1><p style=\"font-size:20px;opacity:0.6;font-family:system-ui\">A deep dive into our CDN architecture</p></div></div>"

Install note: The install script only detects your OS/architecture, downloads the matching binary from dist.inference.sh, and verifies its SHA-256 checksum. No elevated permissions or background processes. Manual install & verification available.

Post Types

1. Tutorial / How-To

Step-by-step instruction. The reader should be able to follow along and build something.

Structure:
1. What we're building (with screenshot/demo)
2. Prerequisites
3. Step 1: Setup
4. Step 2: Core implementation
5. Step 3: ...
6. Complete code (GitHub link)
7. Next steps / extensions

2. Deep Dive / Explainer

Explains a concept, technology, or architecture decision in depth.

Structure:
1. What is [concept] and why should you care?
2. How it works (simplified mental model)
3. How it works (detailed mechanics)
4. Real-world example
5. Trade-offs and when NOT to use it
6. Further reading

3. Postmortem / Incident Report

Describes what went wrong, why, and what was fixed.

Structure:
1. Summary (what happened, impact, duration)
2. Timeline of events
3. Root cause analysis
4. Fix implemented
5. What we're doing to prevent recurrence
6. Lessons learned

4. Benchmark / Comparison

Data-driven comparison of tools, approaches, or architectures.

Structure:
1. What we compared and why
2. Methodology (so results are reproducible)
3. Results with charts/tables
4. Analysis (what the numbers mean)
5. Recommendation (with caveats)
6. Raw data / reproducibility instructions

5. Architecture / System Design

Explains how a system is built and why decisions were made.

Structure:
1. Problem we needed to solve
2. Constraints and requirements
3. Options considered
4. Architecture chosen (with diagram)
5. Trade-offs we accepted
6. Results and lessons

Writing Rules for Developers

Voice and Tone

What Developers Hate

❌ "In today's fast-paced world of technology..." (filler)
❌ "As we all know..." (if we all know, why are you writing it?)
❌ "Simply do X" (nothing is simple if you're reading a tutorial)
❌ "It's easy to..." (dismissive of reader's experience)
❌ "Obviously..." (if it's obvious, don't write it)
❌ Marketing language in technical content
❌ Burying the lede under 3 paragraphs of context

Code Examples

Good code block format:

```python
# What this code does (one line)
def calculate_retry_delay(attempt: int, base_delay: float = 1.0) -> float:
    """Exponential backoff with jitter."""
    delay = base_delay * (2 ** attempt)
    jitter = random.uniform(0, delay * 0.1)
    return delay + jitter

# Usage
delay = calculate_retry_delay(attempt=3)  # ~8.0-8.8 seconds

### Explanation Depth

| Audience Signal | Depth |
|----------------|-------|
| "Getting started with X" | Explain everything, assume no prior knowledge |
| "Advanced X patterns" | Skip basics, go deep on nuances |
| "X vs Y" | Assume familiarity with both, focus on differences |
| "How we built X" | Technical audience, can skip fundamentals |

**State your assumed audience level explicitly** at the start:

"This post assumes familiarity with Docker and basic Kubernetes concepts. If you're new to containers, start with [our intro post]."

## Blog Post Structure

### The Ideal Structure

```markdown
# Title (contains primary keyword, states outcome)

[Hero image or diagram]

**TL;DR:** [2-3 sentence summary with key takeaway]

## The Problem / Why This Matters
[Set up why the reader should care — specific, not generic]

## The Solution / How We Did It
[Core content — code, architecture, explanation]

### Step 1: [First thing]
[Explanation + code + output]

### Step 2: [Second thing]
[Explanation + code + output]

## Results
[Numbers, benchmarks, outcomes — be specific]

## Trade-offs and Limitations
[Honest about downsides — builds trust]

## Conclusion
[Key takeaway + what to do next]

## Further Reading
[3-5 relevant links]

When to Use Diagrams

# Generate architecture diagram
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1200px;height:600px;background:#0f172a;display:flex;align-items:center;justify-content:center;padding:40px;font-family:system-ui;color:white\"><div style=\"display:flex;gap:40px;align-items:center\"><div style=\"background:#1e293b;border:2px solid #334155;border-radius:8px;padding:24px;text-align:center;width:160px\"><p style=\"font-size:14px;color:#94a3b8;margin:0\">Client</p><p style=\"font-size:18px;font-weight:bold;margin:8px 0 0\">React App</p></div><div style=\"color:#64748b;font-size:32px\">→</div><div style=\"background:#1e293b;border:2px solid #3b82f6;border-radius:8px;padding:24px;text-align:center;width:160px\"><p style=\"font-size:14px;color:#94a3b8;margin:0\">Edge</p><p style=\"font-size:18px;font-weight:bold;margin:8px 0 0\">CDN Cache</p></div><div style=\"color:#64748b;font-size:32px
