ZFS, btrfs, and other software RAID solutions can use mixed drives w/o much issue as long as you make sure that the capacities match or that you set the array up with the smallest disk size in mind.
Do not use hardware raid controllers. They provide no meaningful performance benefit over software raid and make data recovery much more difficultm(if not impossible) in the event of hardware failure.
https://git.mlaga97.space/mlaga97/persistent-live-docker-flake has a builder for a live disk that will mount /dev/sda as ext4 to /persistent, and then start up dockge and whatever containers are present from the previous boot automagically.
OCI as in Open Container Initiative.
I’ve done something extremely similar with a custom NixOS iso for my docker VMs to make versioning and backups easier (golden image live disk with SSH+Docker+Dockge shared between all VMs + local persistent storage specific to each VM).
You can configure frigate via OCI container with custom config, as well as NFS mounts, SSH server, etc and then have a read-only live disk that boots up, mounts NFS share, and then starts up frigate.
Why are you being so condescending about this?
FPGAs are a great tool, but they’re not magic.
They are a great way to prototype ASICs or for performing relatively simple low latency/high-throughput tasks below the economies of scale where actually taping out an ASIC would make sense but there is pretty much no case where an FPGA with a bunch of the same logic path is going to outperform a dedicated ASIC of the same logic.
NPUs are already the defacto ASIC accelerator for ML. Trying to replicate that functionality on an FPGA fabric of an older process node with longer path lengths constraining timing is going to be worse than a physically smaller dedicated ASIC.
It was the same deal with crypto-mining, the path for optimizing parallel compute is often doing it badly on a GPU first, moving to FPGA if memory isn’t a major constraint, then tape out ASICs once the bugs in the gateware are ironed out (and economies of scale allow)
And that doesn’t even begin to cover the pain of FPGA tooling in general and particularly vendor HLS stacks.

I have had the Sandisk Ultra Luxe 512GB version for a few years now with Ventoy on it and have been very pleased with it. I keep a cheap USB-C to USB-A attached to it and that lets me use it with my phone or on any computer.
“What is your favorite self-hosted application?” had what looks to be about 15 matrix responses.
Would potentially be interesting to see Matrix/XMPP/etc prevalence in future surveys, maybe replacing ‘what activitypub apps’ with a more generic ‘what federated apps do you self-host’
I think shared hosting there is more meant to refer to the older “upload your files in webmin and we’ll shove them in /cgi-bin/ with everybody else’s”-style hosting where multiple users sites are running on a single instance of a webserver versus a VPS giving you a VM with SSH access?
What part were you getting hung up on?
That’s news to me considering the EPA-rated fuel economy of vehicles with both hybrid and pure ICE drivetrains is universally higher for the hybrid versions.
An ICE vehicle needs a much larger engine than is truly necessary due to the inefficiencies and limitations of mechanical transmissions, whereas a hybrid can have a much smaller, more efficient engine.
A hybrid can potentially act like a ‘perfect’ transmission, capable of taking in power from an engine running at its single most efficient RPM and, with the aid of battery storage, produce any combination of speed and torque that has an average power less than the output of the ICE.
If you are dead set on a specifically certificate-backed access control scheme, a VPN with the ability to use the hardware-backed certificate store (such as OpenVPN) is likely easier to set up as it is better supported on mobile devices and doesn’t require application-level support (i.e. everything is protected, not just the apps w/ mTLS support)

I do find rclone to be a bit more comprehensible for that purpose, rsync always makes me feel like I’m in https://xkcd.com/1168/
Must have an android client,support mtls,support attachments and card layout.
ps: pls don’t suggest to save to local storage and sync that.
pls don’t suggest this app that cant do that but its great.
Anyways anyone aware of any app that can do that?
Nope, you seem to be well aware of the options available to you and there isn’t any one single app that meets all of your requirements, so unfortunately we can’t recommend anything at all to you, per your specific request.
You’ll have to build it yourself either from scratch or by taking one of the existing open-source tools and adding the missing functionality.
Looking forward to your pull requests!
Restic and borg are both sorta considered ‘standard’ for doing incremental backups beyond filesystem snapshotting.
I use restic and it automatically handles stuff like snapshotting, compression, deduplication, and encryption for you.
DigitalOcean and Vultr are options that “just work” and have reasonable options available in $5-6/month category.
DO is more established and I’ve used them for nearly 10 years now for a $6/mo VPS and for managing DNS for my domains. Vultr has some much closer datacenter options if you happen to be in the southeast US, rather than basically just covering California and NYC like DO does.
People recommend backblaze B2 as a restic/rclone/borg backend because it works extremely well and is an excellent value compared to other available options at a near-flat $6/TB*month rate.
The reason they ‘force linux users to use their b2 product’ is very specifically done, on purpose, to avoid the exact kind of abuse you want to do, which is upload 18TB of near-incompressible data for them to store for $9/month or less.
Buy a 20TB harddrive and keep it in a fireproof filebox, and maybe another to keep at a friends house. You don’t need cloud backups for media you can reaquire relatively easily, save that for the stuff you can’t trivially replace.
What CPU governor are you using? I saved about 40W idle powerdraw switching to powersave vs the default on a Ryzen 9 3900X.
I ran RAID-Z2 across 4x14TB and a (4+8)TB LVM LV for close to a year before finally swapping the (4+8)TB LV for a 5th 14TB drive for via zpool replace without issue. I did, however, make sure to use RAID-Z2 rather than Z1 to account for said shenanigans out of an abundance of caution and I would highly recommend doing the same. That is to say, the extra 2x2TB would be good additional parity, but I would only consider it as additional parity, not the only parity.
Based on fairly unscientific testing from before and after, it did not appear to meaningfully affect performance.
125W (Less than $15/month) or so for
I generally leave
powerManagement.cpuFreqGovernor = "powersave"
in my Nix config as well, which saves about 40W ($4/mo or so) for my typical load as best as I can tell, and I disable it if I’m doing bulk data processing on a time crunch.
What happens if the NAS dies though? What does recovery look like?
Is it possible to recover the data from the drives without Synology’s OS? If so what is that process and how difficult is it to do correctly?
I know that with ZFS, recovery is independent of vendor OS and/or hardware, so if the hardware dies you can just throw the drives into any COTS system with enough ports, but I’m genuinely unsure if that is the case for Synology or not.
