  • IIRC the RTL chip inside them was originally designed for TV, so it works great! I’m actually using very cheap AliExpress clones for the TV ones, because they otherwise don’t work very well.

    I’m also using the outdoor TV antenna on my roof (common in Australia, idk elsewhere), and a splitter and adaptors. And with that I get every channel with no artifacts, at 30% strength, but that’ll probably be higher with not awful SDRs.


  • I’ve got an interesting setup I’d like to share:

    So I’ve got a Raspberry Pi with 4 RTL-SDRs, 2 for TV, 1 for radio, and 1 for plane transponders. That runs SatPi for the 2 TV SDRs, which TVHeadend running on my main server connects to, to record and stream. Jellyfin also connects to TVHeadend to properly index everything and for easy access to recordings and live TV.



  • Will I see any performance increase?

    Like others have said LLMs mostly use VRAM, they can use system RAM if you’re running them on CPU, but that’s ridiculously slow.

    It will however increase the speed of your compile times, which is especially useful if you’re compiling something large like the Linux kernel on a regular basis.

    I’m also worried about not having ECC RAM.

    If you are using it purely for LLMs, if it’s going to get bit flips, it’ll happen in VRAM.

    If you are compiling large things for customers, I’d recommend ECC, just in case, e.g. you don’t want a bricking firmware from a bit flip. But according to EDAC and my TIG stack, my server’s ECC RAM has never even detected an error in the past year, if I understand EDAC properly, so it’s really not important.



  • Is it possible to send the hint from OPNsense itself?

    Yes, to me it sounds like you’re already getting a big enough prefix from your ISP (all devices getting a /64), but you’ll have to request a bigger prefix from OPNsense. I believe it should give you the options to do this when you set the IPv6 mode to DHCPv6 on OPNsense, but I can’t say if your ISP router will handle it.











  • Came across these HP NC522SFP 10Gb NICs

    Yeah I have one and they’re pretty good, and I haven’t had an issue using it with generic stuff.

    any 10Gb SFP switch

    Some switches from bigger companies (like the ones listed on fs.com products) are vendor locked, but you should just need a DAC cable compatible with the switch to work.

    a transceiver to get the link from the ISP to the router

    Correct! Make sure to get an ethernet/10GBase-T one, because there are other transceivers.

    would be easy enough to do some fiber runs there, and it’s all short.

    I did forget to mention that you would need more transceivers to convert between the fibre and SFP+, and they are rated for up to different lengths but they should reduce their power for shorter distances. They also come in different speeds too, but unless you’re really strapped for cash, it’s not worth it to go below 10G.

    I currently have a 300m ones doing a run of 30m, and I’m about to do a 10m run too. Also these are about AU$10-$20, I find FTLX8571D3BCLs the cheapest, but there are others. (I actually got mine for free off a guy on Reddit)
