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. For simplicity, this page treats IOPS as a proxy for/predictor of latency.

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 comes recommended as of mid 2024. The smaller 2TB drive should last an Ethereum full node until early 2025 or thereabouts, with crystal ball uncertainty. The Portal team aim to make 2TB [last forever with EIP-4444](https://

SSH autentimine ID Kaardiga - muljeid aastast 2019

(English version below)

Juhiseid, kuidas ID-Kaardiga logida SSH kaudu sisse on kirjutatud juba 2011 aastast. Kirjutan natuke oma tähelepanekutest 2019 aastal ning ka sellest, kuidas kasutada ID Kaarti Windowsis Puttyga.

Smartcardi kasutamine võimaldab SSH ligipääsu erinevatest masinatest nii, et ei pea hakkama igas masinas võtmeid genereerima või masinate vahel võtmeid kopeerima. ID Kaart peaks olema enamustel Eestlastel olemas olema, seega hea võimalus on seda ära kasutada.

Docker compose as a systemd unit

Create file /etc/systemd/system/[email protected]. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

Add default values to ACF Repeater Fields

I came across this solution when I had about a ton of posts (200+) with values in various PDFs. I didn't want to have to spend time filling out the same values over and over again.

Walkthrough

This case is pretty straight forward; I have one repeater field field_123a56b7cb890 that has a text fields inside it (field_588a24c3cb782). I haven't tried any other types like post objects or radio buttons, but I'm sure it can be done.

Step 1. Hook into acf/load_value on your repeater field. You can use type/key/name as desired here.

OverEncrypt

This is a guide that I wrote to improve the default security of my website https://fortran.io , which has a certificate from LetsEncrypt. I'm choosing to improve HTTPS security and transparency without consideration for legacy browser support.

WARNING: if you mess up settings, lose your certificates, or decide to no longer maintain HTTPS certs, these steps can and will make your domain inaccessible.

I would recommend these steps only if you have a specific need for information security, privacy, and trust with your users, and/or maintain a separate secure.example.com domain which won't mess up your main site. If you've been thinking about hosting a site on Tor, then this might be a good option, too.

The best resources that I've found for explaining these steps are https://https.cio.gov , https://certificate-transparency.org , and https://twitter.com/konklone

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
