I’ve seen some that activate an insane number of breakpoints, so that the page freezes when the dev tools open. Although Firefox let’s you disable breaking on breakpoints all together, so it only really stops those that don’t know what they’re doing.


I have no idea how CoW interacts with NTFS

With btrfs you can disable COW for specific files, that might give you a little performance boost.


Cloudflare tunnels uses a QUIC connection between the cloudflared on the server and Cloudflare itself, which is encrypted similarly to HTTPS.

Whatever protocol cloudflared uses to talk to your webserver locally is configurable through the Cloudflare access web UI (just change http to https). I’ve actually got it configured to use unix sockets, which lets me treat it differently in my nginx config.


It’s probably blocked for whatever reason (maybe less than 90 days old?)

My work and Uni do the same thing, they don’t do full SSL inspection, so most websites don’t need a custom certificate authority; but if the SNI is blocked then they need a custom certificate to hijack and display a blocked message, most browsers will detect this as a MITM and display a not secure message instead.


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.


Looks like 2x 4 pin fan headers:

But yeah I’ve got an AliExpress X99 board, which threw all sorts of hardware errors, had no fan speed control (100% all the time), no working hwmon sensors, and I ended up buying a used Supermicro board instead.


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.


If the HOA’s router supports UPnP/NAT-PMP/PCP then you might be able to use that to get some ports forwarded.


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.


I have also added all Cloudflare IPs in Jellyfin’s known proxies

You should only need to add the IP of the last proxy before reaching Jellyfin, which would be Caddy.


If you can’t get the VPS to work, alternatively there’s Cloudflare but last I checked streaming was a little out of their free terms. With it, you should just have to set your AAAA record and make the cloud orange, that way Cloudflare will proxy it, and IPv4 will work. There’s also Cloudflare tunnels which lets you host websites without port forwarding anything.


In theory PWAs can be configured to run offline, whether they’re doing that I don’t know.

The desktop app looks like it’s electron though.


That’s not really your code, more so you haven’t setup a .gitignore to not commit not your code.


And I really should get used to how debian works with su.

I only know because installing sudo is usually the very first thing I do whenever I have to install it haha.


I might be wrong, but I believe Debian ships without sudo, only su by default (or at least if you configure a root password in the setup).


I’ve run kill -9 and similar heaps before, but weirdly this comment reminded me of this: https://youtu.be/Fow7iUaKrq4


A lot of external status services just send a HTTP request to a certain url, if it succeeds then it’s up, if it errors or times out then it’s down. They also usually let you check if TCP ports do the usual handshake thing if you aren’t using HTTP.

The response time can also be used to check if a site is running slower than usual too, and if you have a use for it you can usually specify the required response code for success.

Although I wouldn’t be surprised if GitHub has some per-server analytics they can also use to estimate the load, but Instatus would work as described above.

Sometimes these sorts of things are referred to as health checks, if you’re looking for search terms. For example Docker can be set up to poll a container’s web server every few minutes, and mark it as unhealthy it if it stops replying using the HEALTHCHECK instruction in the Dockerfile.


Nah, apparently it’s completely valid to end IPv6 addresses with a 0. And I haven’t done much research, but it seems IPv6 really doesn’t have network addresses the way IPv4 does.

Also you can ping them and they reply.


On the ISO keyboards I’ve seen, the enter key has way more than double the surface area than ANSI, so it’s definitely not ‘just rotated 90 degrees’. Also these people probably grew up with ISO and struggle with ANSI, just like you probably grew up with ANSI and struggle with ISO.


I doubt this will be any use, but my Telstra 4G has a public IPv6.


Yeah, I’d avoid the cloud version, but SNMP monitoring on the networked version is nice when you want multiple things to shutdown without relying on a single host.


Cloudflare Tunnels will let you proxy any port, as long as it’s HTTP(S) or SSH, even on free tier.

Also I believe there’s a thing now for proxying other ports anyway on free tier without tunnels, but I haven’t looked too much into it.



if you want to use different SSID for different VLAN

With newer versions of the controller you can actually use PPSK for a different VLAN per password (same SSID), but at the moment you’d be stuck using WPA2.


That’s true, but because of that you can get Cisco certifications, which could be helpful if you end up in an network related job. Those certifications will also give you a lot of knowledge of how networks work. (I’m currently completing a CCNA, and quite enjoy it)

A few other companies also clone the Cisco CLI, so there’s that too. I wouldn’t touch the Web UI if it has one though.


He’s saying you’d probably have more luck finding any simplified photo editor, rather than limiting yourself to just hosted. Something like MS Paint or KolourPaint but I don’t believe they will let you rotate text.


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)


Outlook has had this for a while, and I use it a fair bit to acknowledge that I’ve read the email, but without actually replying.


Also 10G is really cheap if you go with used SFP+ gear. Like I’ve got a managed 48x 1G + 4x 10G Dell switch I got for AU$78 running my network. The NICs are about US$40 used, ConnectX3s seem the cheapest, I usually use Intel X520s which are a little more (watch out for clones though).

For the accessories: DACs are AU$20 new from fs.com, and because you’ll probably need ethernet for that router, a 10GBaseT transceiver is AU$90 new off eBay. Those you could probably buy cheaper used too.

Additionally you wouldn’t be adding 10G to all your devices, I’d just definitely do between your router so you can have 3 1G devices maxing out your 3Gb internet, and maybe add it to a server or two.

And if you do your own runs, in my experience, fibre is slightly cheaper for the longer runs than CAT6 itself too.


No worries! I’d probably prefer bridge mode instead of double NAT, but I guess whatever works for you.


Or alternatively something like tailscale will also work without port forwarding.


Oh so you’ve got double NAT. You’ll either have to put the modem into bridge mode, or port forward on both the router and modem.


Do you have CGNAT?

If you run traceroute 1.1.1.1 the first hop should be your router, and if the second starts with 100, 10, 172, or 192, then you probably have CGNAT.


Have you port forwarded?

The ports are 80 for http, and 443 for https. Oh, you’re using 9091


It’s missing a bunch of features so I’m pretty sure it can’t do stock CPython, it could probably do a customised version though.


Cloudflare Tunnels have a basic reverse proxy built in, so you could technically still have one and eliminate Traefik.

However, I still use one for nginx, and one for each important app (frigate, home assistant, probably others), plus an extra on a raspberry pi as more of a VPN if my wireguard server goes down.


It’s not an ideal solution, but this guy did the renewal using certbot and just linked the certificate into yunohost for DNS renewal.


You might be able to manually create NS records for @, but I’ve never tried it.


Add an IP to one of the bridges, Proxmox will then use that bridge with that IP.
