We’ve talked about grounding (giving an AI a textbook to look at) and prompting (giving an AI clear instructions). But sometimes, you don't just want the AI to look at a book; you want the AI to become an expert in its bones. This is called Fine-Tuning.
Single-Page Application
This was a new term for me as I started putting together my most recent study guide. SPA, which stands for Single-Page Application. While it sounds like a simple website, an SPA represents a fundamental shift in how web applications function, bringing unique challenges to the world of information security. Understanding SPAs is critical because they are the primary reason tools like PKCE and OIDC became industry standards.
Connecting Code to Capital: Understanding EPS
In the IT sector, we often measure success through “per unit” metrics: requests per second, cost per gigabyte, or tickets per agent. In the world of public markets and executive leadership, the ultimate “per unit” metric is EPS, or Earnings Per Share.
For an IT professional aiming for a managerial role, EPS is the bridge between your technical efficiency and the company’s stock price. It is the single most watched number by investors and the Board of Directors because it reveals how much actual profit each share of the company is generating.
IaC – Infrastructure as Code
The Recipe for Modern IT
In the traditional world of IT, setting up a server was a craft. A sysadmin would log in, click through menus, install packages, and tweak settings until everything worked. I know, I did this job for much of my early career. But much like a chef cooking a complex signature dish from memory, this manual approach has a fatal flaw: human variability. If the chef forgets one pinch of salt or a single sprig of thyme, the dish changes. In IT, we call this Configuration Drift. Infrastructure as Code (IaC) solves this by turning that “memory” into a precise, digital recipe. Instead of manually configuring hardware or virtual machines, you write machine-readable files that define exactly what your environment should look like.
Cloud Formation Example
Imagine you’re a System Administrator tasked with setting up a new environment. Traditionally, this involves a long checklist: log into the console, click through menus to create a VPC, spin up three VMs, configure storage, attach security groups, and set up a load balancer. If you need a second environment for testing, you have to do it all over again, and hope you didn't miss a single checkbox. AWS Cloud Formation turns that manual checklist into a text file.
