Scala examples

Three small, self-contained Scala scripts. Each is meant to be readable on its own; together they're a quick tour of a few patterns I keep reaching for in Scala.

File	What it shows
`file_reader_writer.scala`	Loan-pattern helpers (`withFileWriter`, `withFileReader`) that handle resource cleanup so the caller can focus on what to write/read.
`flexible_fizz_buzz.scala`	FizzBuzz refactored to take a callback, so the what to do with each value is a parameter rather than `println` hardcoded.
`recursive_messages.scala`	Indented threaded-message printer over a parent/child message structure, demonstrating `Option` matching for the parent reference.

AWS EC2 Instance Types -- Quick Reference

Family	Specialty	Use Case
F1	Field Programmable Gate Array	Genomics research, financial analytics, real-time video processing, big data, etc
I3	High Speed Storage	NoSQL DBs, Data Warehousing, etc
G3	Graphics Intensive	Video Encoding/3D Application Streaming
H1	High Disk Throughput	MapReduce-based workloads, distributed file systems such as HDFS and MapR-FS
T2	Lowest Cost, General Purpose	Web Servers/Small DBs
D2	Dense Storage	Fileservers/Data Warehousing/Hadoop

AWS CloudFormation templates

Two CloudFormation stacks I've reused across personal AWS accounts.

File	What it creates
`private_vpc_stack.yml`	A `/16` private VPC with both IPv4 and Amazon-provided IPv6, plus four `/24` subnets across the first four AZs of the region. Each subnet auto-assigns IPv6 addresses.
`dns_host_management_stack.yml`	A Route53 hosted zone for a domain you pass in as a parameter, pre-populated with the MX, DKIM, and SPF records Fastmail needs to deliver mail. The stack output prints the nameservers you'll point your registrar at.

Usage

GitHub Codespaces cheatsheets

Two short reference docs I wrote up while getting Codespaces to play nicely across teams using different IDEs and trying not to blow through the free-tier hours.

File	What it covers
`codespaces-prebuilds-cheatsheet.md`	When prebuilds save you money vs. when they cost you more, the trigger and retention settings that matter, and how to monitor prebuild storage so you don't hit a surprise bill.
`devcontainer-jetbrains-vscode-codespaces.md`	Writing a single `devcontainer.json` that works in JetBrains IDEs, VS Code (remote-containers), and Codespaces -- which features and lifecycle hooks each runtime supports, and how to avoid the gotchas where they diverge.

Both are written as practical checklists rather than overviews -- skip to the section you need.
