Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

Set Icon to a File / Folder on macOS

Since macOS High Sierra sips --addIcon is no longer supported. An easier way to add and image to a file/folder is to use fileicon npm package.

The new syntax is:

fileicon set foo img.png

1. Create a new Telegram bot:
   1. start a chat with BotFather;
   2. type /newbot, select a name (to be shown in chats) and handle for your bot;
   3. note the bot token to access HTTP API - a long string with a colon in the middle (later referred to as <token>);
   4. optionally /setdescription and /setuserpic.
2. Add the bot to the chat/channel and note its id:
   1. add the bot to a new or existing chat or group - this is where your bot will send notifications to;
   2. go to https://api.telegram.org/bot<token>/getUpdates (replace <token> with your token);
   3. within the chat part, find and note the id field - a positive or negative number (later referred to as <chat_id>).
3. Programmatically send notifications:

// simplevm.c: demonstrates Hypervisor.Framework usage in Apple Silicon
// Based on the work by @zhuowei
// @imbushuo - Nov 2020

// To build:
// Prepare the entitlement with BOTH com.apple.security.hypervisor and com.apple.vm.networking WHEN SIP IS OFF
// Prepare the entitlement com.apple.security.hypervisor and NO com.apple.vm.networking WHEN SIP IS ON
// ^ Per @never_released, tested on 11.0.1, idk why
// clang -o simplevm -O2 -framework Hypervisor -mmacosx-version-min=11.0 simplevm.c
// codesign --entitlements simplevm.entitlements --force -s - simplevm
