Don’t use btrfs if you need RAID 5 or 6.

The RAID56 feature provides striping and parity over several devices, same as the traditional RAID5/6. There are some implementation and design deficiencies that make it unreliable for some corner cases and the feature should not be used in production, only for evaluation or testing. The power failure safety for metadata with RAID56 is not 100%.

I don’t think I’ve ever seen a public WiFi network with IPv6 enabled. I usually just use the hotspot on my phone to access my server since my cell carrier provides IPv6. I do have a VPN as a backup though.

Single board computers have GPIO and interfaces like SPI and I2C. They also tend to have lower power consumption and can run from 5 volts. If you want to interface with low level hardware or run from batteries, the SBC will usually be the better choice.

I would get a recertified enterprise drive from Server Part Deals. Drives in the 12-18TB range currently have the best price per TB. Be sure to get a SATA drive if it’s going in a desktop.

You don’t get segmentation faults if you don’t have an MMU. That can certainly make debugging more interesting when your firmware starts overwriting memory that it shouldn’t until it finally crashes.

For a dual port card, you will want an 8 lane PCIe 3.0 slot connected to the CPU. Almost any desktop CPU will have enough lanes since you won’t be using a graphics card. You can get by with a 4 lane slot, but you won’t be able to max out both ports bidirectionally at the same time.

In Thunderbird you can move the emails to a local folder and they will be fully downloaded.

Just use yt-dlp. It’s not hard to use. You just type yt-dlp, paste the video link, and press enter to download the highest quality version.

Does your windows machine have WSL? I would just write a bash script that would DD the image to the drives. Keep in mind that you will be severely bandwidth limited by the USB interface, so it will take a long time. All of the ports on the controller share the same bandwidth. Ideally you would build a PC with lots of USB controller cards for that.

I will still use it for testing things, but I will no longer use it for installing the OS on a PC I’m going to use until they get the BLOB issue sorted out.

That would be my suggestion. They only take a single slot and some are even passively cooled.

Inkscape is good for making icons, assuming you want vector icons.

If you are just self hosting for your own use, just stick with letsencrypt or self signed certificates.

The paid certificates are for businesses where the users need to trust the certificate. They usually come with warranties and identity verification, which is important if you are accepting payments through your website, but it’s just a waste of money for personal use.

Donate to FOSS developers if you find the software useful, but don’t give a cent to big tech companies.

That works until the battery puffs up and cracks the screen. Phones don’t last long when plugged in 24/7. Also keep in mind that WiFi cameras can easily be jammed.

It used to, but it’s had the option to save an actual video for a long time now.

Most devices generate a random IPv6 address and change it frequently. Your browser fingerprint is much more useful for device tracking than your IP address anyways.

Just because each device has a globally routable IP address doesn’t mean they can be accessed from outside your LAN. You still have to add a firewall rule to open a port to the device.

It’s only decent until you need to do something the GUI doesn’t support. Then it will overwrite whatever you changed in the CLI or luci every time it boots up.

10,000 and 15,000 rpm drives were made obsolete by SSDs and were discontinued several years ago. They are slower than many modern 7,200 rpm drives.
