Everything runs 24/7, but now I am thinking about theoretical power saving modes. Besides any built in power saving whatever (a little clueless), you could always throttle the CPU more. Not sure if it would be worth it without testing with a power meter.

Sorry, didn’t make it home until today and not sure if you get notifications on edits. You will need a monitor and keyboard hooked up to your server as you will not have ssh access until the network config is “fixed”. I would do the below with the GPU removed, so you know 100% that your networking config is correct before mucking about further.

Step 1 - Create 99-default.link file

Add a /etc/systemd/network/99-default.link with the below contents.

# SPDX-License-Identifier: MIT-0
 #
 # This config file is installed as part of systemd.
 # It may be freely copied and edited (following the MIT No Attribution license).
 #
 # To make local modifications, one of the following methods may be used:
 # 1. add a drop-in file that extends this file by creating the
 #    /etc/systemd/network/99-default.link.d/ directory and creating a
 #    new .conf file there.
 # 2. copy this file into /etc/systemd/network or one of the other paths checked
 #    by systemd-udevd and edit it there.
 # This file should not be edited in place, because it'll be overwritten on upgrades.

 [Match]
 OriginalName=*

 [Link]
 NamePolicy=mac
 MACAddressPolicy=persistent

Step 2 - Reboot and find new name of NIC that will be based on MAC

I forget if you have to reboot, but I am going to assume so. At this point, you can get the new name of your nic card and fix your network config.

1. ip link should list all of your nic devices, both real and virtual. Here is how mine looks like for reference, with the MAC obfuscated:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enxAABBCCDDEEFF: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master vmbr0 state UP mode DEFAULT group default qlen 1000
    link/ether AA:BB:CC:DD:EE:FF brd ff:ff:ff:ff:ff:ff
3: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether AA:BB:CC:DD:EE:FF brd ff:ff:ff:ff:ff:ff

Step 3 - Fix your network config and restart network manager

You will need to edit your /etc/network/interfaces file so the correct card is used.

1. Make a copy of /etc/network/interfaces, just in case you mess something up.
2. sudo vim /etc/network/interfaces (or whatever text editor makes you happy) It will need to look something like below. I have to have DHCP turned on for mine, so your config likely uses static. Really all you need to do is change wherever it says enp yada yada to the enxAABBCCDDEEFF you identified above.

 source /etc/network/interfaces.d/*

 auto lo
 iface lo inet loopback

 iface enxAABBCCDDEEFF inet manual

 auto vmbr0
 iface vmbr0 inet dhcp
 #iface vmbr0 inet static
 #address 192.168.5.100/20
 #gateway 192.168.0.1
     bridge-ports enxAABBCCDDEEFF
     bridge-stp off
     bridge-fd 0

3. Restart your networking service. You shouldn’t need to reboot. sudo systemctl restart networking.service

Step 4 - Profit?

Hopefully at this point you have nework access again. Check the below, do some ping tests, and if it doesn’t work, double check that you edited the interfaces file correctly.

1. sudo systemctl status networking.service will show you if anything went wrong and hopefully show that everything is working correctly
2. ip -br addr show should show that the interface is up now.

lo               UNKNOWN        127.0.0.1/8 ::1/128
enxAABBCCDDEEFF  UP
vmbr0            UP             192.168.5.100/20 

At this point, if all is well, I would reboot anyways, just to make sure. If you add any GPUs, sata drives, other PCI device, disable/enable wifi/bt in the BIOS, or anything else that changes the PCI numbering, you don’t have to worry about your NIC changing.

I am not at home, but what I did was change the 99-default.link file. I found this from the two pages below. https://wiki.debian.org/NetworkInterfaceNames#CUSTOM_SCHEMES_USING_.LINK_FILES https://wiki.debian.org/NetworkInterfaceNames

Basically, by doing this, your nic cards will be forcibly named using the mac address:

#/etc/systemd/network/99-default.link
 [Match]
 OriginalName=*

 [Link]
 NamePolicy=mac
 MACAddressPolicy=persistent

Afterwards, you will need to reboot and then update your network config file to use the correct names. I don’t ever change the network config with the GUI in proxmox as it has wrecked it too many times. I will update this reply again later with some more information on what to do.

I changed my settings to name nic cards by mac address instead of the enumeration as I got sick of the name changing when I would add/remove pci devices.

This is so damn wholesome. Thank you fellow humans for helping this person and even offering to pay. Why I am cutting onions this early in the day is a mystery.

I started 30 minute backups earlier. It updates from the yuzu repo and downloads all of the releases from yuzu-mainline if there are new ones. Anything else I should also backup?

I wouldn’t have a clue where to put this stuff on the interwebs, but if shit happens, I will be 1 of many backups I guess.

I am getting flashbacks on dealing with SAP “inspired” software that looked worse than that bottom image. I am glad my new company does not use that garbage. It was especially depressing to see how SAP entirely ruined Concur.

What is even more painful is seeing friends glued to TikTok on their phones all day when they have STEM degrees. I didn’t grow up in a typical household, so I have a hard time relating to other women, but I don’t get it either. Do your friends with kids seem to be this way more than those without?

I wonder if the $300 is sort of like extra startup money to get better hardware, infrastructure, software improvements in the short term. I honestly have no idea. I pop on there sometimes to watch the full length videos from YouTube and there is some really great content, but not necessarily enough. Their UI/apps could definitely use some work, though I have not checked recently.

I really hope they continue to run and it looks like I need to catch up on some content. I took a break from most YouTube/TV/etc. I cancelled all of my other subscriptions, but I have no reason to not support a company like Nebula, especially at their price points.

I am not going to debate the ethics of piracy or people’s justifications for or against it. It isn’t productive. I do think this is an instance where you are better off paying for a month than spending a lot of time trying to get it another way. Sometimes, I like to put things in the perspective of I make X dollars an hour, how many man hours did I spend to do X task? Cost benefit analysis. This isn’t always practical, thus the “sometimes”.

For the love of all that is unholy, learn and get comfortable with the command line. Go install WSL if you are on Windows. Not saying you have to be a master, but learn how to compile your code manually, get around the OS, tab complete, grep, ps, and other simple commands. Learn the basics of a text editor. vim/emacs/nano. Just pick one or two. Learn how to redirect output to standard and error out. Simple shell scripts.

Debugger. If you do not know how to set breakpoints, with or without conditions, and inspect variables, go learn today. I have junior developers that can’t do this.

Critical thinking and investigation. This is a rather loaded term, but your problem solving skills will go a lot farther than how your code looks. Bad but working code can be improved. Alternative solutions can be found. You at least understand the problem and an approach to take. If you don’t understand how something works, figure it out. Ask your senior team members. Spend time in the debugger and the source code, if available. Good documentation doesn’t always exist. You will not always find the perfect answer or tutorial on the Internet. If you are going to use code off the internet, you damn well better understand how it works and how to expand on it.

Keep up with the standards and updates to the languages you use. A lot of tutorials can be out of date fairly quickly. Newer language features can be a huge boon and you get a sense of where that language is going. Older ways of using libraries and languages can be hard to avoid, but make an effort to check. Speak up to your seniors if you find something that may be useful or if something is now considered bad practice.

Look at source code on GitHub/GitLab/Whatever and then the all mighty practice.

In my opinion, once you can get a handle on the above, then you can go back and learn more advanced principles, algorithms, read textbooks, and things like that. They will make a lot more sense. This may seem a little opposite than what most people would say, but for me a lot of the things I learned in school or read previously started to click.

C# is my happy place. Started doing python more over bash scripts for complicated stuff and I like it. I mostly use Java for work and my opinion of it depends on the how much extra effort I had to spend doing something I could have done in C# in a few minutes. Otherwise it has some nice features and project Panama has been a game changer.
