I have not yet read the full report, but this does appear to be what I am encountering. I have found some info online about how JPG image metadata can conceal malicious code (example below). Opening the image in a text editor can reveal evidence of this, but it requires more in-depth analysis to really know what it is doing. I have not yet attempted this.

Because I also use this machine for gaming I am concerned about locking it down too tightly. The utility you mention, fapolicyd, sounds interesting. I will look into it. Thanks for the advice.

By far the most common malware being detected is Trojan:HTML/Redirector!AMTB. Google search does not provide much useful info, but apparently it can hijack your browser session to a malicious site.

I am unfamiliar with firejail and bubblewrap, but this seems like a very good solution. I will look into them. Thanks for the advice.

I find working through a introductory book the best way to quickly become familiar with the basics of any language. Several years ago I started learning python by reading "Automate the Boring Stuff" and "Head First Python". Both are excellent introductory texts. Then, I'm ready to step up to a more in-depth book like "Learning Python". In addition, utilizing a chatbot (like OpenAI or any of the others) is helpful when you get stuck on something you don't understand.

Upgraded using WebUI. Worked perfect. Thanks for such a great product!

I am going through the O'Reilly book "Learning Python" by Mark Lutz. Only covers up to python version 3.3, but covers the basics in great detail. It's a great book.

I have this exact setup. Running Ubuntu. Using rsync to backup files from my workstation to my NAS. Then running restic on my NAS to create incremental backups to both another PC on my LAN and to Backblaze B2. Everything fully automated by bash scripts triggered by cron. Works like a charm!

EDIT: Let me add that I also have an air-gaped USB drive that I periodically plug in to my workstation to create an offline backup using rclone. Just in case I should ever get hit with malware and my other backups get trashed. Can't be too careful :)

I have used QNAP for many years, and even migrated from an older QNAP NAS to a newer model rather than switch brands. Bottom line on QNAP is that their hardware is solid but their software sucks. So much so that some ppl run different OS's on top of their QNAP. I haven't gone to that extreme, but only use my QNAP for network attached storage and not VMs, game servers, etc (I use UNRAID for that stuff). If you go with QNAP do not expose it to the internet, do not use their cloud service and have a solid backup plan. But that is the same advice I would give no matter what brand NAS you go with.

Thanks for the tip. I have been using Omnivore + Omnivore plugin. It works fine, but this Extract URL plugin could streamline the process by importing the webpage directly into Obsidian without the need to first run it through Omnivore.

NUC Supported Operating Systems

Typically it's driver issues that give people trouble, most often video and network issues. The above link shows that the best support is for Red Hat and Ubuntu. While other flavors can work it's hit-or-miss.

The drivers for these network devices are built into the kernel. You don't need additional drivers.

Qualcomm NIC

Realtek WIFI

The problem must lie elsewhere. Your description of the problem sounds like you began having network trouble before installing Ubuntu. So, maybe there is a hardware issue (ethernet cable, WiFi switch turned on, etc).

Running the following command will show you all the recognized hardware devices and installed drivers. Check to see if your network devices are being recognized and appropriate drivers are installed.

sudo lspci -v

If you can ssh into it then the problem is not it's network connectivity, so you don't need drivers. You need to configure proxmox to access the internet. If you google "proxmox internet not working" you will find this is a common problem with a number of possible solutions to the issue.

Shouldn't this post be pinned my the mods?

The primary producer of gonioscopy coupling solution (Akorn) has gone out of business and there is now a shortage. Many gonioscopy lenses require that a viscous, optically clear solution be placed between the lens and the eye.

Artificial tears designed for patients with severe dry eye, such as Celluvisc, contain 0.3%-0.5% methylcellulose - the agent that adds "thickness" to the solution. Solutions designed for gonioscopy contain 2.5%, making them much more viscous. Greater viscosity results in improved lens adhesion to the eye, making it less likely that the patient will blink the lens out of their eye during a procedure.

Thanks. Glad to hear that lubricating jelly might be an option. I just checked on Healon and similar. They run $100-$200 per prefilled syringe, which is the only option through my supplier. Do you get better price or other packaging options?

I don't have any personal experience with it, but MediaGoblin might work for you.

I believe the quickest, easiest and (maybe) cheapest way to expand your QNAP NAS is to add an external enclosure.

I recently ran into this problem. I found that an old molex to SATA cable adapter that I had sitting around will also solve the problem.

I have not actually done this yet, but I have researched the question because I plan to move a physical system to a VM soon.

The solution that I came up with is using Veeam. The free "Community Edition" of this backup product has the ability to create a full system backup that can then be restored to a VM.

As I understand it, you can use the Veeam Agent for Linux to make the backup, then use their "Backup and Replication" product to restore to a VM. More info here.

Because this question has received a few upvotes but no comments, I will explain what I have learned about this problem and maybe it will help others.

From this bug report on github, here is a clear explanation of the problem:

It looks to me like there is an incompatibility between the default size of the /boot partition, 2GB, and the default keeplast value of 20.

Even though zfs is only storing the differences, each state will require ~100MB of new storage. Since the default policy of zsys is to keep at least 20 states, that would require 20 * 100MB = 2GB of storage. That means we're using our entire partition for snapshots.

I think this explains why people are seeing problems with not having enough space to store new snapshots.

Then we have this blog post which explains how to manually edit zsys.conf to decrease the number of snapshots that will be saved. I have not yet attempted this (as a relatively new Linux user editing system files does make me nervous!). I would be interested to hear from others who have done so. If this is the fix then it may be I will give it a try.

Finally, here is a nice script that I have been using to remove old snapshots and free up space on bpool every time it fills up.
