I recently upgraded my rancher RKE cluster to 1.20.4, and found that nfs-client-proisioner is broken. It failed to create new PVC with an "unexpected error getting claim reference: selfLink was empty, can't make reference" error.

After some google search I found this. However, there is no documentation on how to migrate from nfs-client-provisioner, even it seems to fixed the issue.

When asking around in #sig-storage, @thansen suggested to give democratic-csi a try, which has a crude yet simple implementation of nfs-client as a CSI driver.

Here's capture how I get it to work, after helps from @thansen

My setup: RKE cluster on k8s v1.20.4, 3x Fedora 33 node, managed by Rancher 2.5.6, NFS server on a Thecus N5550, nfs-client-provisioner used for dynamic PVC provisioning.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Pixelbook or Pixel Slate Setup

Partly updated June 2023

General caution: Chrome OS is a secure OS by design, but this has at least one key consequence. If you change your Google account password, you will still be required to enter the old password the next time you access each Chrome OS device. Devices are encrypted with that password, so the OS needs to decrypt using the old password then re-encrypt using the new one. If you forget your old password you will lose access to your Chrome OS device data. As always, make sure you keep backups up to date.

Fast User Switching

If you have multiple Chrome OS accounts (Say, work and play), you can quickly sitch between them without logging out:

Dumping games with Godmode9

Dumping games is the act of taking a game from your system or gamecart and copying it into a readable format onto your SD card. Dumping is perfectly legal if you keep the dumps to yourself, however sharing these dumps is piracy and is illegal.

This guide will tell you how to dump games from various formats and for various purposes. Dumping 3DS cartriges as .cia files is good if you want to install them to your system. Dumping them as .3ds files is good for emulators. Installed titles cannot be dumped as .3ds files. NDS cartiges can only be dumped as .nds files and cannot be installed (however, you can play them with emulators or flashcarts).

Dumping the RomFS of a game is primarily for romhacking purposess.
