Queue Revolution: Từ Xếp Hàng Một Người Đến Dây Chuyền Sản Xuất
22:00 – Vừa nghĩ ra 5 ý tưởng blog tuyệt vời trong lúc tắm.
22:30 – Chạy task đầu tiên: “Docker debugging tips”
23:00 – Task 1 xong, chạy task 2: “Kubernetes scaling”
23:30 – Task 2 xong… ủa 3 ý tưởng kia là gì nhỉ?
Notebook ghi vội:
- Docker something
- K8s… monitoring? management?
- Redis (chắc vậy?)
- ???
- Profit?
Đây là câu chuyện về đêm tôi nhận ra: mình cần một hàng đợi như McDonald’s.

The Bottleneck Problem: One Thing At A Time
Workflow cũ của tôi simple đến đau lòng:
Tôi: "Team ơi, viết blog về Docker"
*Chờ 20 phút*
*Check email, lướt Facebook*
*Quên mất đang chờ gì*
Tôi: "À xong rồi! Giờ viết về... ủa về gì?"
*Check notebook*
"K8s something..."
Tôi: "Team ơi, viết về K8s... scaling? security? Thôi general K8s đi"
The Creative Flow Killer:
- Brain dump ideas: 10 phút (lúc inspired)
- Execute từng idea: 3-4 tiếng
- Ideas còn nhớ sau: 2/10
- Ideas viết sai topic: 3/10
- Frustration level: OVER 9000
Tôi đang manually làm scheduler. Và tôi là worst scheduler ever.
McDonald’s Enlightenment Moment
11:45 PM. Đói. Ra McDonald’s gần nhà.
Đứng chờ burger, nhìn lên màn hình order:
Order #101: 🍔 Preparing
Order #102: 🍟 Queued
Order #103: 🥤 Queued
Order #104: 🍦 Queued
Tôi đứng đó, nhìn màn hình, Big Mac trong tay.
“Khoan…”
“Nếu blog posts cũng có queue như vậy thì sao?”
Cắn burger suy tư
Designing The Queue System (On Napkins)
Về nhà, vẽ trên khăn giấy McDonald’s còn dính sốt cà chua:
QUEUE SYSTEM:
┌─────────────┐ ┌─────────────┐ ┌─────────────┐
│ PENDING │ --> │ PROCESSING │ --> │ COMPLETED │
│ ┌─────────┐ │ │ ┌─────────┐ │ │ ┌─────────┐ │
│ │ Task 3 │ │ │ │ Task 1 │ │ │ │ Done 1 │ │
│ ├─────────┤ │ │ └─────────┘ │ │ ├─────────┤ │
│ │ Task 2 │ │ └─────────────┘ │ │ Done 2 │ │
│ └─────────┘ │ │ └─────────┘ │
└─────────────┘ └─────────────┘
The Dream Interface:
# Morning brain dump
queue add "Docker debugging at 3am"
queue add "Why K8s hates developers"
queue add "Redis saved my marriage"
queue add "PostgreSQL nightmares"
queue add "That thing about Nginx"
# Start processing
queue process --all
# Go live life
Building The Queue: Midnight Engineering
12:00 AM – Creating Structure
mkdir -p queue/{pending,processing,completed}
# Test với empty files
touch queue/pending/test_task_1
mv queue/pending/test_task_1 queue/processing/
mv queue/processing/test_task_1 queue/completed/
"It works!"
1:00 AM – Task Format Design
Mỗi task cần identity và metadata:
{
"id": "task_20240105_013025_abc123",
"title": "Docker Debugging at 3AM",
"type": "blog",
"priority": "normal",
"created": "2024-01-05T01:30:25Z",
"status": "pending",
"requirements": {
"tone": "casual",
"length": "1500 words",
"keywords": ["docker", "debugging", "containers"]
}
}
2:00 AM – The Queue Management Script
queue-task.sh ra đời:
#!/bin/bash
# Queue task - Because my memory worse than goldfish
queue_add() {
local title="$1"
local priority="${2:-normal}"
# Generate unique ID
local timestamp=$(date +%Y%m%d_%H%M%S)
local uuid=$(uuidgen | cut -c1-8)
local task_id="task_${timestamp}_${uuid}"
# Create task file
cat > "queue/pending/${task_id}.json" <
The Processing Magic
The Simple Loop That Changed Everything
process-queue.sh:
#!/bin/bash
# Process queue - Work while I sleep
process_queue() {
local processed=0
echo "🚀 Starting queue processor..."
echo "📋 Pending tasks: $(ls queue/pending | wc -l)"
while true; do
# Get next task (priority first)
local next_task=$(ls queue/pending/*urgent* 2>/dev/null | head -1)
if [ -z "$next_task" ]; then
next_task=$(ls queue/pending/* 2>/dev/null | head -1)
fi
if [ -z "$next_task" ]; then
echo "✨ Queue empty! Processed $processed tasks"
break
fi
# Atomic move to processing
local task_name=$(basename "$next_task")
if mv "$next_task" "queue/processing/$task_name" 2>/dev/null; then
echo "⚙️ Processing: $task_name"
# Extract task details
local title=$(jq -r .title "queue/processing/$task_name")
# Create blog with Growth Engine
./growth-engine-v3.sh create "$title"
# Move to completed
mv "queue/processing/$task_name" "queue/completed/"
((processed++))
echo "✅ Completed: $title ($processed done)"
fi
# Coffee break every 5 tasks
if [ $((processed % 5)) -eq 0 ] && [ $processed -ne 0 ]; then
echo "☕ Taking a 5-minute break..."
sleep 300
fi
done
}
First Night With Queue
3:00 AM - Time to test:
# Brain dump everything
queue add "Docker multi-stage builds explained"
queue add "K8s pod debugging tricks"
queue add "Redis Lua scripting magic"
queue add "PostgreSQL query optimization"
queue add "Nginx rate limiting deep dive"
queue add "AWS cost optimization hacks"
queue add "Git bisect saved my job"
queue add "Python async/await finally clicked"
queue add "That weird bug at 3am"
queue add "Why I love/hate JavaScript"
# Check queue
ls queue/pending | wc -l
# 10
# Start processing
nohup ./process-queue.sh > queue.log 2>&1 &
# Go to sleep
6:00 AM - Wake up:
ls queue/completed | wc -l
# 10
ls outputs/
# 10 fresh blogs ready to publish!
Tôi: happiness noises
Unexpected Discoveries
Discovery #1: Priority System Saves Relationships
Một buổi sáng:
Vợ: "Anh nhớ viết blog về anniversary chúng ta chứ?"
Tôi: "Nhớ chứ!" check queue "Ơ... nó đang #27 trong queue..."
Vợ: "..."
Quick implementation:
queue add "Our Love Story: Tech Edition" "urgent"
# Process urgent first
ls queue/pending/*urgent* | head -1
Crisis averted!
Discovery #2: Agents Develop Context Awareness
Sau vài ngày, agents bắt đầu "thông minh" hơn:
Analytics: "Hmm, 3 bài Docker liên tiếp.
Có vẻ đang làm Docker series?"
Content: "Tôi sẽ reference bài trước cho consistency!"
SEO: "Docker series trending! Suggest hashtag #DockerWeek"
Unplanned feature: Contextual intelligence!
Discovery #3: The Productivity Metrics
Queue system tự động track metrics:
queue_stats() {
echo "📊 Queue Analytics"
echo "=================="
echo "Total queued: $(ls queue/*/ | wc -l)"
echo "Completed today: $(find queue/completed -mtime -1 | wc -l)"
echo "Average time: ~20 min/task"
echo "Success rate: 98%"
echo "\n🏆 This Week:"
echo "Mon: 5 posts"
echo "Tue: 7 posts"
echo "Wed: 6 posts"
echo "Thu: 8 posts"
echo "Fri: 4 posts"
echo "Total: 30 posts!"
}
Evolution of the Queue
V1: Basic Folders (Week 1)
pending/ → processing/ → completed/
# Simple but works
V2: JSON Metadata (Week 2)
{
"title": "...",
"queued_at": "2024-01-05T10:00:00Z",
"started_at": "2024-01-05T10:30:00Z",
"completed_at": "2024-01-05T10:50:00Z",
"duration_minutes": 20
}
V3: Project Organization (Week 3)
projects/
├── docker-series/
│ └── queue/
├── k8s-deep-dive/
│ └── queue/
└── daily-randoms/
└── queue/
V4: Current - Full Automation (Week 4)
# CSV bulk import
./import-ideas.sh blog_ideas.csv
# Auto-process on schedule
crontab: 0 */2 * * * /path/to/process-queue.sh
# Slack notifications
"✅ Queue processed 5 tasks. 10 remaining."
The Beautiful Chaos
Typical morning routine now:
$ queue status
📊 Growth Engine Queue Status
============================
⏳ Pending: 23 tasks
🔄 Processing: 1 task (Docker security)
✅ Completed: 147 tasks (this month)
Next in queue:
1. "Why YAML is evil" (priority: normal)
2. "Terraform saved my weekend" (priority: normal)
3. "Anniversary post" (priority: urgent)
Estimated completion: 7.5 hours
Coffee needed: Yes ☕
Bugs and Lessons Learned
The Duplicate Processing Bug
# Two processes grabbed same task
# Both moved pending → processing
# Chaos ensued
# Solution: Atomic operations
mv -n "pending/$TASK" "processing/" || continue
The Infinite Retry Loop
# Failed task stuck in processing forever
# Agent kept retrying every minute
# API bill: 📈
# Solution: Max retries + failed queue
if [ $RETRIES -gt 3 ]; then
mv "processing/$TASK" "failed/"
fi
The "Completed" Disk Explosion
# Never cleaned completed tasks
# 6 months later: 10,000 files
# ls took 30 seconds
# Solution: Auto-archive
find queue/completed -mtime +30 -exec tar -rf archive.tar {} \;
The Numbers Don't Lie
Before Queue System:
- Ideas captured: ~30%
- Ideas executed: ~10%
- Weekly output: 3-5 posts
- Stress level: High
- Weekend work: Always
After Queue System:
- Ideas captured: 100%
- Ideas executed: 95%
- Weekly output: 25-30 posts
- Stress level: "What stress?"
- Weekend work: Optional
Final Thoughts
Queue system không sophisticated. Không dùng Kafka, RabbitMQ, hay Redis. Chỉ là folders và bash scripts.
Nhưng nó transformed cách tôi work:
- No more forgotten ideas
- No more manual scheduling
- No more "what should I write next?"
- Just queue and forget
Từ developer stressed về content creation, giờ tôi là "content factory owner" relaxed.
Questions for fellow developers:
- Bạn manage creative ideas thế nào?
- Team "batch everything" hay "real-time processing"?
- Longest queue bạn từng handle?
P.S: Nếu bạn đang manually track tasks trong notepad, build a queue. Any queue. Your future self will thank you.
