Gmail Address Equivalence: Dots, Case & Plus-Tag Aliases

BLUF: For consumer @gmail.com accounts, three orthogonal rules apply: dots in the username are ignored, capitalization is ignored, and +tag suffixes deliver to the same inbox. A.B.C@gmail.com, abc@gmail.com, and AbC+Shop@gmail.com all reach the same mailbox. This does not fully apply to Google Workspace (custom domain) addresses — dots may matter there.

Quick Reference (TL;DR with Examples)

Given the address johnsmith@gmail.com, all of these deliver to the same inbox:

Claude Code: Conditionally Loading Plugins with --plugin-dir

Overview

Claude Code supports loading plugins on a per-session basis using the --plugin-dir flag. This is additive — it loads the specified plugin(s) in addition to all normally installed/enabled plugins. It does not replace them.

A plugin directory is identified by having a .claude-plugin/plugin.json manifest inside it.

DECFRA / DECERA and Sixel Graphics Interaction: Research Notes

TL;DR

Whether DECFRA/DECERA clear sixel pixel data is terminal-dependent, not standardised. The VT420 spec defines DECFRA as a text-plane operation only. On real VT340 hardware, DECERA did not affect sixel graphics. xterm added sixel-clearing to DECFRA/DECERA in patch #370 (2021), but this is an xterm extension adopted by some modern terminals.

Understanding SSH Host Aliases ("Pseudo-Domains") for Git Multi-Account

The Core Concept

When you see github.com-work in an SSH config or git remote URL, that is NOT a real domain name. It's an SSH host alias (sometimes called a "pseudo-domain") — a label that only exists in your ~/.ssh/config file. It never hits DNS.

# This is an ALIAS — "github.com-work" is a made-up name
Host github.com-work
 HostName github.com # ← the REAL server to connect to
