Not as hard as I thought at least to cover the essentials. This has recently come up twice for me, first DHH talked about Linux security as locking the front door<\/a> then in this guide on setting up a production-ready VPS<\/a> (A+ guide BTW). Similar steps were mentioned in both but I\u2019ll review the latter since it\u2019s my current use case.<\/p>\n

For fresh installs start by creating a new user account with sudo<\/code> permissions. Copy my public SSH key from my local laptop to the remote server. Then lock down SSH access to non-root users and disable password authentication only key-based authentication is allowed.<\/p>"},{"title":"Replace Docker Desktop with Colima","link":"https:\/\/rigomoran.com\/colima\/","pubDate":"Tue, 01 Oct 2024 00:00:00 +0000","guid":"https:\/\/rigomoran.com\/colima\/","description":"

Ever since Docker Desktop changed is pricing model I\u2019ve been using Rancher Desktop as a replacement. Its works fine but I recently noticed a few coworkers using Colima<\/a>.<\/p>\n

Note: For individual users Docker Desktop is still free<\/p>\n<\/blockquote>\n

Colima, is short for Containers on Lima<\/a>. Where Lima is a separate tool Which aims bring Li<\/strong><\/em>nux virtual Ma<\/strong><\/em>chines to macOS and Linux. Apparently its used by Rancher Desktop and Podman Desktop under the hood. Colima is a minimal CLI with sensible defaults that provides container runtimes for macOS. Its compatible with the latest and greatest versions of Docker BuildKit & Compose.<\/p>"},{"title":"Debugging Git GPG Signing Issues","link":"https:\/\/rigomoran.com\/debug-git-gpg\/","pubDate":"Sat, 10 Aug 2024 00:00:00 +0000","guid":"https:\/\/rigomoran.com\/debug-git-gpg\/","description":"

I’m relatively new to signing my commits. And I recently stumbled into a new somewhat cryptic Git error. Here’s what I did to debug the problem. Hope it helps you.<\/p>\n

The scenario:<\/strong> You have Git configured to use a GPG signing key for your commits. You craft a solid commit message, hit enter, and…<\/p>\n

> git commit -m -S "my awesome commit"<\/span>\n<\/span><\/span>\n<\/span><\/span>error: gpg failed to sign the data\n<\/span><\/span>fatal: failed to write commit object\n<\/span><\/span><\/code><\/pre><\/div>
So Git was not able to write our commit due to some issue with GPG. Since we don’t know what the actual problem is or what a potential fix could be we need to dive deeper.<\/p>"},{"title":"Using Python Debugger PDB","link":"https:\/\/rigomoran.com\/using-python-debugger\/","pubDate":"Thu, 21 Mar 2024 00:00:00 +0000","guid":"https:\/\/rigomoran.com\/using-python-debugger\/","description":"Summary of the example"},{"title":"Tapping into GenAI","link":"https:\/\/rigomoran.com\/tapping-into-genai\/","pubDate":"Wed, 21 Feb 2024 00:00:00 +0000","guid":"https:\/\/rigomoran.com\/tapping-into-genai\/","description":"A Step-by-Step Guide for Querying Your Snowflake Data Warehouse with LangChain & AWS Bedrock"},{"title":"Enable dark mode for kitty, fish, Neovim","link":"https:\/\/rigomoran.com\/theme-toggle-for-kitty-nvim\/","pubDate":"Thu, 25 Jan 2024 00:00:00 +0000","guid":"https:\/\/rigomoran.com\/theme-toggle-for-kitty-nvim\/","description":"Summary of the example"},{"title":"Experimenting with Google APIs","link":"https:\/\/rigomoran.com\/google-api-playground\/","pubDate":"Tue, 23 Jan 2024 00:00:00 +0000","guid":"https:\/\/rigomoran.com\/google-api-playground\/","description":"
Working with Google APIs can feel overwhelming due to the variety of APIs, processes around authentication\/authorization, requesting appropriate scopes, and navigating all the available libraries.<\/p>\n
Here’s the breakdown:<\/p>\n
    \n
  1. \n
    Select an API and the required scope<\/p>\n<\/li>\n
  2. \n
    Request a Refresh Token<\/em> and Access Token<\/em><\/p>\n<\/li>\n
