Smart Caps Lock: Remap to Control AND Escape (Linux, Mac, Windows)

把 Caps Lock 變成智慧的 Control 以及 Escape ：

單獨輕按一下就是 Escape 。
若按下時同時按著其他鍵，就會是 Control 。

這應該是 Vim 和 Emacs 的最佳解了！(Emacs? Bash 的快捷鍵就是 Emacs 系列的)

Send Escape if you tap Caps Lock alone.

ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

Purpose of Proxmox cluster project

A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

	#!/bin/sh

	echo "This script updates your moodle installation."
	echo "You will need a few pieces of information to complete this process."
	echo ""
	echo "Warning: This will disable Web-Access to the moodle installation!"
	echo "Make sure nobody is logged in at the moment or activate maintenance mode manually so no data is lost."
	echo ""
	echo ""

	# Setup OpenVPN Server
	#
	# Edit variables below and copy paste the script
	# in a MikroTik terminal window.
	#

	:global CN [/system identity get name]
	:global COUNTRY "UA"
	:global STATE "KV"
	:global LOC "Kyiv"

	#!/usr/bin/env python
	# -- coding: utf-8 --
	from argparse import ArgumentParser

	import torch
	import torch.distributed as dist
	from torch.nn.parallel import DistributedDataParallel as DDP
	from torch.utils.data import DataLoader, Dataset
	from torch.utils.data.distributed import DistributedSampler
	from transformers import BertForMaskedLM
