OP here, I looked into it. For legal reasons I will neither confirm nor deny any marketing claims here and let the experts decide. I will merely list the equipment I bought. [0] [1] [2] [3]

[0]: https://www.amazon.de/dp/B01EXDG2MO - "TP-Link TL-SG108 V3 8-ports Gigabit Network Switch"

[1]: https://www.amazon.de/dp/B07WG8TNDL - "CSL Cat 7 Network Cable, Gigabit, Ethernet, LAN Cable, PiMF Shielding With RJ 45 Connector, Switch, Router, Modem Access Point, White"

[2]: https://www.amazon.de/dp/B06XCYC4K7 - "deleyCON 5 x 0.5 m Cat7 Network Cables, Short, 10 Gigabit, RJ45 Patch Ethernet Cable, Copper, SFTP PiMF Shielding, LAN, DSL for Switches, Modems, Router, Patch Panels, Cat6, Cat5 Compatible, Black"

[3]: https://www.amazon.de/dp/B089MF1LZN - "Amazon Basics 30.5m White Flat RJ45 CAT7 Gigabit Ethernet Patch Internet Cable"

One copy of each would run you around 75-85 euros in total by my napkin math. Sticking with standard CAT 6A would have probably been 10-15 euros cheaper, and since I'm only aiming for 1 Gbps, not 10, I might have been able to get away with CAT 5e, even.

I suspect that the additional hours of time I would have had to spend actually doing my research here to make a fully informed purchase would have made this a slightly net negative decision financially. But that's mostly because of the small size and modest needs of the network I was wiring up. If I were wiring up anything that scaled beyond my own apartment it would have been valuable to know this, so thank you, my career will go better as a result of this correction.

So everything I say in this comment is unlikely to have any real impact if you were to replace the cables and retest, but I'm saying it for educational purposes. The reason the specs are strict is not because it cannot be done on less but because the acceptable margins for error and risk are lower in non consumer settings.

That switch does have metal around the ports but I could not find any indication in a datasheet that it designed to accept shielded cables. I also don't know what other devices you are connecting to the switch. Proper usage of shielded twisted pair needs the shielding to make contact to ground on both sides of the cable. I was taught years ago that using a shielded cable with neither side grounded or just one side grounded had the potential to turn the shielding into an antenna and make interference worse than with an unshielded twisted pair cable.

The flat cable is concerning. Flat cables are not part of any twisted pair spec. There tends to be two kinds of flat ethernet cables. The first being completely flat with no twisted pairs at all and the second kind having each pair twisted around each other but then the four pairs are parallel in the falter sheathing. The second kind is better and from the pictures that cable might be the second kind. However 33 meters is very long for a flat cable. Ideally you shouldn't use them but if you have to keeping them very short like under 2 meters is ok.

The pages for the other two cables never even show the cables but what looks like 3d renderings. I personally do not like that and it makes me think less of the vendors. I doubt any of the three cables would pass a full qualification test for Cat7 but they are probably completely indistinguishable from qualified Cat5e (since you are only using 1g) unless you are using them next to high voltage power conduits or next to a high power broadcast antenna. This just comes down to "Cat7 consumer products are a marketing scam."

Sad if true. I was a donor, and the program had good intentions.

At least now instead of just theory we have one study of the results and a data point to use in the next attempt at a similar project. The idea is probably still solid and could be attempted again but with a more refined implementation.

OP mentions using "Cat 7" cables - please don't buy these. Cat 7 isn't something that exists in TIA/EIA standards, only in ISO/IEC and it requires GG45 or TERA connectors. Cat 7 with RJ45 connectors isn't standardized, so you have no idea what you're actually getting. Stick with pure copper Cat 6A.
Arrowmaster · 8 days ago
Absolutely agreeing with you but replying to you instead of multiple others below with my views on this.

Cat6A can do 10Gbps at 100m. Cat7 and Cat8 can do higher speeds in short runs but those technologies are DEAD in DC tech now. 40G is legacy tech using four lanes of 10G, replaced by 100G which is four lanes of 25G. Copper patch cables are not used with these, everything is fiber or DAC.

If you use a Cat7 or Cat8 cable the higher MHz support listed on the spec will never be used. When using a real cable of these qualities all you are really getting is better protection from outside interference.

When buying premade patch cables only buy Cat6A. Anything you see online saying Cat7 or Cat8 has probably never been properly tested by the manufacturer.

When buying a spool of wire do your research on the manufacturer. There's plenty with false labels out there. I once saw a spool of 'Cat6e' which is not a real standard.

When paying others to run cables find out what brand and what warranty the installer is providing. If they only use Cat7 and cannot provide a good explanation on why they might not actually know as much as you should be expecting them to.

Yup, came here to say this. After reading the article, it became abundantly clear that the author doesn’t support Linux and most of the article is just a summary of the common Tauri talking points that are out of date. To add data to this - Tauri is looking to allow embedding chromium as an option because the creator of Tauri acknowledged that it doesn’t work well on Linux. To the point where if Linux is a serious target, they don’t recommend Tauri: https://github.com/tauri-apps/wry/issues/1064#issuecomment-2...

The upstream projects aren’t in a place to support this yet so this feature didn’t make it into Tauri v2. I’ve been tracking this for a long time and hope that they will make it possible in v3.

Thanks for the link. That's great info to know but it's only part of the problem. If they think changing out the renderer will fix everything then they haven't learned anything.

Their build action creates seriously flawed AppImages for Linux for multiple reasons that have nothing to do with the renderer but with the AppImage creation process.

Why should they exit a car over a speeding ticket? A speeding ticket is not a jail sentence and does not warrant an arrest. In fact unless a driver is actively trying to harm somebody or has an active arrest warrant there is no reason whatsoever for them to leave their car or allow cops to remove people from cars.
Arrowmaster · 15 days ago
In the sovereign citizen cases they are talking about, the typical case is that the vehicle is not registered/doesn't have plates and the driver refuses to identify themselves. They only barely lower the window if at all. They usually go back and forth a few times until the police tell them they are under arrest for multiple reasons relating to driving without a license and failure to identify.

The glass breaking happens after multiple offices have arrived for backup as the person usually gets dragged from the car screaming. The videos are extremely entertaining to watch.

The combination of unregistered vehicle, failure to prove the driver has a license, and the drivers insisting they should be allowed to drive away is absolutely a combination where arrest is legal.

Sadly, every time that one guy posts his personal finance app on HN I try it and every time tauri gives me trouble to build, and when I fix whatever build errors it gives me it basically opens up a blank window and the app doesn't work (He now offers a Docker image which I can't help but feel is related to these difficulties).
Arrowmaster · 16 days ago
I think the blank window bug was caused by a change in the libraries used by the webview on Ubuntu 22.04 used by suggested build action. Details and fixes were spread across bug reports in multiple downstream projects but afaik it was fixed in an Ubuntu update.

The idea of AppImages is neat, but the implementation is awful and rarely works (except perhaps on Ubuntu and Fedora and extremely similar scenarios).

The main issue being that they're dynamically linked binaries, which is exactly what you want to avoid for their use case.

Using packages from your favourite distribution is usually your best bet.

Arrowmaster · 16 days ago
AppImages are supposed to be able to handle all of that and I have used a number of them that do. In the case of Tauri though it seems nobody on the framework team knows Linux well enough to fix the build process to not constantly break as libraries update on the GitHub Ubuntu VMs or to make all the required dynamically linked libraries get included in the AppImage. And finally most of the downstream app developers have never written an app for Linux and chose the framework expecting it to solve the problems it clearly isn't.

The author has obviously never tried Tauri on Linux. I've never seen one of their AppImages work correctly. Every project uses the upstream GitHub action to build binaries and it compiles dynamically linked binaries limited to the glibc from the Ubuntu 22 or 24 VM used. Xdg-open is often broken too from broken environment variables in the AppImages, so you can open a link in the default web browser. The entire build process needs reworked.

Nvidia GPU? Their drivers have been broken on Linux for a long time now. I've had no bugs on my steam deck or on asahi linux with wayland.

Steamdeck doesn't use Wayland.
