    Proxmox with LVM-thin and why we should use Trim/Discard

Excerpts from the Proxmox VE Administration Guide]

LVM normally allocates blocks when you create a volume. LVM thin pools instead allocates blocks when they are written. This behaviour is called thin-provisioning, because volumes can be much larger than physically available space.


8.10.2. Trim/Discard
It is good practice to run fstrim (discard) regularly on VMs and containers. This releases data blocks that the filesystem isn’t using anymore. It reduces data usage and resource load. Most modern operating systems issue such discard commands to their disks regularly. You only need to ensure that the Virtual Machines enable the disk discard option.

    HP Smart Storage Admin CLI (ssacli) installation and usage on Proxmox PVE (6.x)

Why use HP Smart Storage Admin CLI?

You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS.  That means no host downtime when managing your storage.
CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.
ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.

    @preston_vanloon's plugins

Be sure to watch the YouTube stream where we talk about how these plugins work in depth.
These two plugins helped me get into the top 10 of the dark forest score contest for v0.5.
auto-conquer is a plugin that would find the best planets to conquer. It is currently tweaked for late game, so you'll have to read the code and change parameters if you are just starting out!
auto-silver is a plugin to re-distribute silver mines to available planets. It's also tweaked for late game, ignoring silver mines with small amounts of silver.

This swagger site hosts the service interface definitions for the Ethereum Serenity JSON API.

## Service Overview

At the core of Ethereum Serenity lies the "Beacon Chain", a proof-of-stake based blockchain managing a set of validators and "shards" across a network, which are stateful, smaller blockchains used for transaction and smart contract execution. The Beacon Chain reconciles consensus results across shards to provide the backbone of Ethereum Serenity. The services below allow for retrieval of current and historical information relating t
