tax payer subsidies

It’s not subsidies, it is tax breaks if companies go there. A very different thing.

The future of ethernet is not expensive cabling, more like switches capable of doing more on current cables. We’ve been seeing this trend for a while.

So what, people need cloud services and Netherlands did the same and became one of the top spot for datacenters in Europe and nobody is bitching around.

I’ve done my fair share of long runs of Cat6e 23 AWG with PoE and they all work fine and gigabit on distances like 100 meters or close. Sometimes even slightly above that.

Staggered will reduce the failure rate by a lot, specially if you’re into gigabit speeds or anything above it. Although I know from experience that you can get gigabit on non-staggered connectors it won’t always happen on the first try. On long distances the noise caused by having the wires side by side may also cause problems.

Btw, if you’ve small patch cables don’t use solid core for those, those should be stranded cables and they’ll be more flexible, less likely to break when bent and less prone to bad contacts.

CCA wasn’t probably your issue there, CCA is actually becoming the standard everywhere because copper is way too expensive and to be fair not needed with modern hardware.

You most likely issue with that CCA is the AWG size you picked, cheap cable is usually 24, 26 or even 28 AWG and those will be bad.

If you want PoE or anything gigabit or above you need to pick 23 AWG. This is considerably cheaper than full copper and it will work fine for the max. rated 100m. Either way, cheap 26 AWG should be able to deliver gigabit and PoE at short distances like 20 meters or so.

Another important thing is to make sure your terminations are properly done and the plugs are good. Meaning, no Cat5e connectors should be used, always use staggered ones:

I’ve a run of around 60 meters of old telephone cables (made out of copper, 4 wires) and I can get 100Mbps on those reliably. I used the old telephone infrastructure on the building to pass network from an apartment to the basement that way.

Not to spec on ethernet on any way, not even twisted pairs but they do work. Unfortunately I can’t replace the run with a proper Cat6 cable because there’s a section that I can’t find where it goes to, it just disappears on a floor and appears 2 floors bellow it inside the main telephone distribution box.

On the distribution box (that is already on the basement of the building) I’m plugging into the LSA connector that goes to the apartment:

The black box you see there is a mikrotik gper that is essentially a PoE switch with only 2 ethernet ports so I can get over the 100m limitation of ethernet. I’m running a cat6 cable from there on metal cable trays for about another 90 meters until it reaches a storage unit 2 floors bellow ground.

Here’s a ping test from a machine sitting on the storage box to the router on the apartment:

The router reports this as a 100M full-duplex connection:

If anyone wants to try a setup like this, or just extend ethernet > 100m, it also worked fine with a cheap 5$ 100M switch from Aliexpress and a PoE injector + splitter.

However I eventually got the mikrotik gper for free so I decided to replace it because it should be more reliable.

Yes but… tests are done in controlled environments and ideal conditions, there are big real world differences with CCA vs fully copper or those solid core options vs stranded ones. They’ll all perform differently depending on distances, noise immunity will vary and will break differently in different ways when tension is applied. You can also get Cat5e on different AWG sizes, all spec compliant but all very different from each other.

The bottom line is: it all comes down to how much you’re willing to spend.

It may do more at short distances with good connectors and if fully copper. The OP definitely had poor termination and/or broken wires.

It depends on the type of application and size. For your typical business app / backoffice with tons of fields on the same page and real time data reactivity makes sense, otherwise it doesn’t.

Not only C, I’ve had experiences with real time applications in Angular and React pushing like 100 updates a second and it’s really easy to fuck something up that will trigger change detection and subsequent calls to death and create a scenario like that.

Oh but it did, first the GD-ROM that had 1GB and the only way to get the games into a CD was to cut the assets making it a worse experience and… playing recorded CD-ROMs on a Dreamcast was a very efficient way to destroy its drive.

You’re correct, and now people will boycott Chrome. Firefox and Brave are good / accessible / easy to get for most people so…

Here’s the thing, you now know you’ve to replace the battery every 3 years or so, but I’ve SONY batteries running for 5 years and they’re fine. Now, your motherboard’s manufacturer is a piece of shit, the board should’ve just ignored the issue and proceeded to the OS. All modern operating systems sync the UEFI time whenever they get time from NTP so no need to halt the boot process.
