Writing an apt proxy conf file /etc/apt/apt.conf.d/proxy.conf as below.

Acquire::http::Proxy "socks5h://127.0.0.1:1080";
Acquire::https::Proxy "socks5h://127.0.0.1:1080";
Acquire::socks::Proxy "socks5h://127.0.0.1:1080";

And the proxy settings will be applied the next time we run apt.

Sepolia is now on PoS

As of 2022/7/6, Sepolia has switched to PoS. The window to do some mining has closed.

Testnets after merge (original, old content from here)

It's mid 2022, Ethereum is still PoW and motoring towards merge / PoS. Surviving testnets will be Sepolia - currently PoW - and Goerli. Ropsten will be merged and then deprecated, Rinkeby and Kovan won't be merged.

I want to "get ready" for some Sepolia testing pre- and post-merge. Sepolia will not have a public validator set; testing post-merge will be limited to running applications on it. As Sepolia is PoW, I can actually go mine myself some SepplETH. Here's how.

	#!/bin/bash
	target=${1:-http://example.com}
	while true # loop forever, until ctrl+c pressed.
	do
	for i in $(seq 100) # perfrom the inner command 100 times.
	do
	curl $target > /dev/null & # send out a curl request, the & indicates not to wait for the response.
	done

	wait # after 100 requests are sent out, wait for their processes to finish before the next iteration.

	pragma solidity ^0.4.24;
