- A historical time-windowed token crowdsale
An old Solidity experiment that changes a token conversion rate across a fixed sale window.
Blockchain - A Homebrew architecture mismatch on early Apple Silicon
The difference between a Rosetta process and an ARM Homebrew prefix in an older M1 setup.
Tools & experiments - A January 2021 Apple Silicon compatibility note
A small historical record that should not be mistaken for a current software or pricing recommendation.
Tools & experiments - A pending transaction is not the same as a canceled transaction
Correcting an older Bitcoin/Ethereum troubleshooting note around node visibility, nonce replacement, and confirmation.

An older IBFT 2.0 infrastructure notebook, with genesis identity, validator health, and storage estimates separated.
Cloud & systems / Blockchain - A recorded HP Z420 memory-training error
A workstation boot error and the power-management settings recorded during the earlier investigation.
Tools & experiments - A recorded iOS and Android lifecycle sequence
An earlier observation of inactive, paused, and resumed transitions.
Mobile & interfaces - A release-only iOS architecture mismatch in Flutter

Mobile & interfaces - A rounded TextField in Flutter
A compact styling note on filled inputs, border radii, padding, and focus states.
