Docker can run on ARM v7 CPU

I am gonna demonstrate how to run a docker engine on an ARM v7 CPU on NanoPC T2, which was released in 2016 on s5p4418 chip.

docker error: level=error msg="failed to mount overlay: invalid argument"

Quick solution: use vfs driver instead of overlay

Summary

I found Synology DSM 7.2.2 supports internal(private) vSwitch with IPv6 support ONLY (without using a physical switch). No IPv4! (I assume Synology won't like users to use internal(private) vSwitch because it costs lots of CPU)

Here's how-to

This issue has been there since many years. It can be found on some forums. Searching links from Google https://www.google.com/search?q=Synology+GPT+PMBR+size+mismatch+%28239649+%21%3D+245759%29+will+be+corrected+by+write.&newwindow=1

I personally enabled 2 pcie-nvme SSD disks as Read-Write cache RAID1 on Synology NAS. Then I disabled them safely from DSM web UI (Storage Manager / Storage / Select your Volume), then I found some error from terminal via command fdisk -l. After I removed the 2 SSDs, the error was still there.

Error: GPT PMBR size mismatch (239649 != 245759) will be corrected by write. reported by fdisk -l via SSH to NAS.

GPT PMBR size mismatch (239649 != 245759) will be corrected by write.
Disk /dev/synoboot: 120 MiB, 125829120 bytes, 245760 sectors
Disk model: DiskStation

2 ethernet interfaces: enp6s18, enp6s19

Need to use enp6s19 as default and use enp6s18 as backup

Principle: set different Metric on different interfaces. The lower Metric is, the higher the priority is.

Need tool nmcli

1. Check route

Run command route

init...

#define LED_D4 13
#define LED_D5 12

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
 pinMode(LED_D4,OUTPUT);

Official Discord Domains, let's reduce the scams!

Domain	Description
dis.gd	Discord's URL shorter (I like .gd as top-level domain)
discord.co	Admin panel, this means not for us! (Not discord administrators / maybe staffs)
discord.com	The domain is for e.g the homepage or message links etc
discord.design	Dribbble profile shortlink
discord.dev	Developer site shortlinks
discord.gg	Invite shortlinks

By time time of writting which is 11th Aug 2024, ChatRTX from Nvidia has only offically supported RTX 30/40 series GPU. I have a RTX 2080Ti which Nvidia has abandoned support.

I don't like this.

So I found out the way of bypassing the ChatRTX installation process on Windows 11 with RTX 2080 Ti.

After finishing downloading all the ChatRTX zip file from Nvidia, find some files in the folder and change it. https://www.nvidia.com/en-us/ai-on-rtx/chatrtx/
