Overview

Syncing an Ethereum node is largely reliant on latency and IOPS, I/O Per Second, of the storage. Budget SSDs will struggle to an extent, and some won't be able to sync at all. IOPS can roughly be used as proxy of / predictor for latency. Measuring latency directly is arguably better.

This document aims to snapshot some known good and known bad models.

The drive lists are ordered by interface and then by capacity and alphabetically by vendor name, not by preference. The lists are not exhaustive at all. @mwpastore linked a filterable spreadsheet in comments that has a far greater variety of drives and their characteristics. Filter it by DRAM yes, NAND Type TLC, Form Factor M.2, and desired capacity.

For size, 4TB is a very conservative choice. The smaller 2TB drive should last an Ethereum full node until at least sometime 2026, with the [pre-merge history expiry](https://hackmd.io/@hBXHLw_9Qq2va4pRt

Обращение к российским IT-специалистам

Коллеги! Армия Путина вторглась в Украину под предлогом «денацификации» и ведёт там грязную войну. У многих из нас есть коллеги из Украины, с которыми можно пообщаться и убедиться в том, что никакого «освобождения» от Путина им не нужно.

Многим из нас сейчас страшно. Но открытое письмо нашей индустрии против этой войны собрало уже более 30 000 подписей. Нас много, и мы уверены, что это не предел.

Правительству тоже страшно: страшно потерять нас. А значит, действия каждого из нас могут помочь прекратить это безумие.

Что делать

Install multipass

https://multipass.run/

Create virtual machine

multipass launch --mem 10G --cpus 6 --disk 20G --name knative
multipass shell knative

Install K3S

K3d and Istio

Prerequisites

Ensure docker, k3d and istioctl installed.

brew update
brew install --cask docker
brew install k3d istioctl

Installing K3s with the external ("out-of-tree") AWS Cloud Provider

Pre-requisites

Refer to the upstream project's official documentation for the various pre-requisites. You must have an IAM role with the right permissions attached to your K3s instances, and you must also tag your nodes with a clusterid. Refer to the Rancher documentation for how to do this

Install K3s with the following options:

curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="server \

Create your own site in the dark web.

There is a lot of misconception around the dark web, and most of the people think that it is not possible to create their own website on Dark web (The Onion network). Today we will set up a website in the Onion/Tor network for free.

As you can see above, I have created my own website in the Tor network, and I've accessed it using the Tor Browser.

	Just import `g` and then access (set/get) attributes of it:
	```python
	from your_project.globals import g
