Data Types Deep Dive

Why should you care? When you write: int age = 20; it looks like you are simply storing the number 20. But the computer needs more information. It needs to know: What kind of data is this? How much space should be used? How should the bits be interpreted? What operations are valid? What range of values can be represented? That is the job of a data type. Understanding dat...

About me and you ?

I'm a game developer who enjoys building things from scratch — from core gameplay loops to the tools that make them possible. I spend most of my time in Unity and Godot, occasionally dropping down to raw C++ when I want more control over performance and memory. I'm drawn to the messy, iterative part of game dev: prototyping fast, throwing out what doesn't work, and polishing the systems that do. ...

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...
