Day 14: AWS Compute — Managed & Serverless

We started the compute layer on Day 13 with EC2, ELB, and Auto Scaling — where you launch and manage everything yourself. Today we move one level up the abstraction ladder: services where AWS takes over more of the operational burden. By the end of this post you'll know what each one does, how it differs from plain EC2, and when to actually reach for it. AWS Elastic Beanstalk Elastic B...

Semantic Caching: The LLM Cost-Killer Nobody's Talking About Enough

TL;DR Traditional caching checks if you've seen the exact same input before. Semantic caching checks if you've seen a meaningfully similar input before — using embeddings instead of string matching. For LLM-backed apps, this can cut API costs by 30–70% and slash latency from seconds to milliseconds, without touching your prompts or model choice. The Problem If you're building anything on top of...

Stop Recreating Database Connections: An Illustrated Guide to Connection Pooling

If you have ever built an application that talks to a database, you have used a database connection. A database is simply a structured storage system for digital information, and a connection is the secure, active pipeline established between your application's code and that database. However, constantly opening and closing these connections for every single user request is incredibly slow and r...

Delivery Exception Detection — Node.js Metrics API Queries Feeding Lambda Webhooks

Short answer: for a small Node.js notification service, poll one delivery-failure metric from a separate scheduled function, evaluate a versioned rule, and send a deduplicated webhook; move to a full incident-management system only when rotations, escalations, and acknowledgement state become requirements. That answer is deliberately narrower than “install an observability platform.” A logistics ...

[AskJS] How much do you actually trust the version number on an npm update?

I'm working through how a team decides whether an automated dependency update is safe to merge, and one of the baselines I'm testing is the obvious one: trust semver. Auto-merge patch and minor, hold majors for review. My assumption is that this baseline is weak — that in practice a meaningful share of breaking changes ship in patch and minor releases, and that a major bump is often just a dropped...

"Image Optimization: The Complete 2026 Checklist for Faster Websites"

Images are the single biggest performance lever on almost every website.

I've spent the past few months obsessing over image compression (I built CompressFast to scratch my own itch). Here's the complete, ordered checklist I use on every project. 1. Resize firs...

CodeFrame: Turning Source Code Into Beautiful Images, Right In Your Browser

Every developer who has ever needed to share code in a slide deck, a blog post, or a GitHub issue has reached for the same two tools: a screenshot, or a manual copy into a presentation tool. Screenshots are blurry and fixed-size. Manual copies lose syntax highlighting and formatting. And the popular web tools that render code to images? They cap out at 2x, because they're secretly taking screensho...

Finding, Verifying, and Adapting the Right Skills for Your Project

Skills are reusable workflows, not magic knowledge pills. Before you install one, inspect its source, versions, and effects to confirm it fits your project. Start with a few focused skills and adapt them to what already exists. A skill is a set of instructions and scripts that lets an agent reproduce a specialized method. It doesn’t guarantee best practices or compatibility with your repository. ...
