Amazon Bedrock Model Catalog and Choosing a Model (AWS Gen AI Series, Part 3)
Bedrock ships more than a hundred models across fifteen providers, and the price gap between the cheapest and the priciest is over 400x. Here is how I read the catalog and pick a model without overpaying.

Amazon Bedrock and the Shared Responsibility Model (AWS Gen AI Series, Part 2)
Bedrock is a managed service, but security is still split between AWS and you. Here is exactly which half is yours, the defaults that catch teams out, and the baseline I deploy before any prompt goes live.

AWS Generative AI Stack, End to End (AWS Gen AI Series, Part 1)
AWS generative AI is really three layers: Amazon Bedrock for managed models, SageMaker AI to build your own, and Trainium and Inferentia underneath. Here is the whole map, with a real cost example and a first call that works.

Customize Your Shell Environment: bashrc, Aliases, and PATH (Linux for Beginners, Part 23)

Backups With rsync and tar, Done Right (Linux for Beginners, Part 21)

Landing Your First Linux Job: Certs, Interviews, and Your First Role (Linux for Beginners, Part 24)
Nobody is hired for reciting commands. Which Linux certifications are worth it, what interviews actually test, how to survive your first 90 days, and a seven-day plan to start now.

Build a Linux Home Lab to Practice Safely (Linux for Beginners, Part 19)
You learn Linux by breaking it and fixing it, which needs a safe place to be reckless. Build a home lab on the laptop you own, use snapshots to undo anything, and practice the whole series.
-
Troubleshoot Linux the Methodical Way, Not by Guessing (Linux for Beginners, Part 18)
The admins who fix things fast follow a method, not a hunch. Define the problem, check the cheap causes first, read the signal not just the number, and change one thing at a time.
-
Basic Security Hardening for a New Linux Server (Linux for Beginners, Part 17)
A fresh server gets brute-forced within minutes. The five changes that stop almost all automated attacks: patch, key-only SSH, a default-deny firewall, fail2ban, and least privilege.
