If there's already a coax cable run what's stopping you from running an ethernet cable alongside it or replacing it?


Coax runs in residential houses tend not to go through conduits, and often squeeze through holes in joists just barely big enough for the cable. Not to mention that, in my experience, they also tend to involve splitters in the absolute most random of locations.

Running Ethernet alongside it is rarely any easier than fishing from scratch.


I haven't run Ethernet, but if I do the drops will be very near the coaxial cables because they're an easy reference.


Laziness. I’d much rather spend $100 on gizmos than spend hours on a home improvement project. And these projects are never as simple as they at first promise to be.


If the endpoints have a hidden fork in between, then what you are shovelling in on one end might not be what comes out the other.


Because he uses MoCa instead.


Only a TOP G understands the matrix


Depends on the country, where I live it's pretty common to have fiber to the home. Everything runs on that, internet, cable tv and phone calls.


Indeed. I had FTTH in Spain, in Andorra 100% of the (tiny) country has FTTH, I'm in the middle of absolutely nowhere in France atm: rural/seaside (about 45 mins to an hour drive to the closest highway) and yet I've got FTTH.

And at my new place in Luxemburg I've got FTTH too.

Fiber to the home is becoming incredibly common in many countries.

My brother had fiber to the home in 2003 already... In Japan (Tokyo).


But in other areas most residential bandwidth increasingly comes from wireless techs. Even in homes with wired service, nearly everyone uses wifi rather than wires, let alone fiber to end machines. The last mile is generally not fiber, nor is it a literal mile.


> nor is it a literal mile.

The cost problem of the last mile is not for the 2 meters between the fiber router in the home and the living room. The issue with the "last mile" is that it used to be excessively expensive to lay fiber everywhere on the, literally, last mile outside people's home.

I could plug a network card with an SFP port and have actual "fiber to the desktop" for the last three meters at my place but I don't. I'm not sure that these three meters where I run ethernet are called a "last mile" (off by a factor of 530x calling 3 meters compared to a mile) ad mean I don't have FTTH or that the last mile ain't fiber.

> ... most residential bandwidth increasingly comes from wireless techs.

What good does it make to laptops and phones using WiFi if the router is doing 40 Mbps max over DSL? It's once you bump that DSL link to FTTH that suddenly all these wireless devices can enjoy much faster speeds. In all the countries I've lived in people at home used WiFi, even from their phone, instead of 4G because 4G means lots of $$$ / EUR.

I think you're underestimating the gigantic speed boost many people are enjoying thanks to fiber (and not thanks to 4G) now that they're having FTTH.


I recently switched from a supposed 900 Mbps Comcast connection to FTTH, and the difference is astonishing. There's just no substitute for Fiber.

And yet it was done for electricity and telephones over a century ago. And fibre probably has a longer 'shelf-life' as it does not corrode, so the initial installation is more likely to last longer.


Indeed many people, including myself are now in the weird backwards world where the WAN is far faster than the LAN.

I have a 3gbps fiber link straight to my house. The only machines in the house that can use anything close to it are the ones that hook up to my USB-C docking station which has a 2.5gbps ethernet port. Everything else is WiFi speeds.

EDIT: This was a sudden change. I live rural and for the last 10 years I only had 10-15mbps speeds top, and most recently only by point to point wireless from a tower 5km away.


The advantage of a fast WAN is you can put it into a capable router (2.5-5-10g) and break it out into multiple clients who can use it simultaneously even if at only 1g each.


This also applies for wireless technology. My phone generally gets a faster connection via 4G, than via WiFi inside my house (the cable connection is fast, but the WiFi is slow). I think because the 4G connection can always see a tower through a window opening, while the WiFi has to go through multiple walls. (No interest in setting up a mesh network as the 4G is plenty fast enough)


This. Only a few years ago Hacker News commenters were crying out for new laws and regulations to subsidize the construction of Google Fiber to every home in America. “It’s a basic human right” they would say.

On the sideline there were a much, much smaller minority who looked at those comments in horror, with the context of knowing that wireless was a serious alternative that wasn’t that far away and was being broadly ignored


>> wireless was a serious alternative that wasn’t that far away

But it really isn't. There are hard physics limits on how much data can be transmitted within a given frequency band. Fiber total theoretical bandwidth is is essentially infinite in comparison. All the traffic of the entire internet could probably flow through a single fiber bundle perhaps less than a meter wide. For things like streaming 4k/8k/12k (real 4/8/12k) to multiple devices, wifi will never compete with fixed lines.


I don't see the problem? I have FTTH. I can get 10 Gbps. I don't want wireless, it's an unreliable last resort. If I have the option I'm absolutely going with fiber.

It's also the better long term tech. Fiber has enormous capacity, while wireless is a shared medium impeded by things like walls, and those problems get worse with the increased frequencies needed for more bandwidth.


The network neutrality discussion belongs in the same bucket. People thought it would be the end of the open internet if there wasn’t a dedicated regulation.


There was dedicated regulation, it was just taken up by states instead of the FCC https://www.techdirt.com/2023/06/12/telecom-industry-ass-kis...


Interesting. I'm not sure "the entire west coast and huge swaths of the midwest and east coast have passed state-level net neutrality laws" is correct if this linked map is to be believed: https://www.naruc.org/nrri/nrri-activities/net-neutrality-tr...

Huge parts of the US apparently do not have such legislation, and it is unclear which states that "proposed" it have put it into law.


Did you take a look at the C++ implementation of the hashing function they did? I didn't see a single call made there. They replaced python code that makes 5 calls into a single call.


That's a copy-pasted variation of this public-___domain SHA1 code: http://ftp.funet.fi/pub/crypt/hash/sha/sha1.c surrounded by base64 decoding and encoding for a known-length binary text.

By inlining all library code you use, yes indeed, you too can also not make a single call.


I didn’t. I expect that it makes a difference, though for the observation that Python native calls are relatively slow.
