Symnetric gigabit connections can be hard to come by in London. If you're served by a niche fibre provider (e.g. Hyperoptic, Community Fibre) then you're golden. There's Virgin (think Comcast) with paltry upload speeds due to the cable tech. Understandable though not ideal. Then there's the OpenReach full fibre network with paltry upload speeds due to... ??? there appears to no good reason, other than not wanting to…

Hyperoptic is niche? I thought they were available all over London.

Not where I am. It's street by street. A lot of areas have no fibre at all, not even OpenReach.

It's cable from Virgin or DSL

We need a whole generation to die off before that becomes likely. In the mean time we should move closer when the opportunity rises.

I'll bite on this one. I've been saying to anyone who will listen here in the states: my generation, the Boomers, needs to die out and/or get the hell out of the way. We're trashing almost everything because of a cult of hero worship.

While I used to agree with you, based on the most recent polling, Gen X and Gen Z are both farther right than Boomers are these days. So we're fucked long term too.

Gigabit Ethernet uses four pairs per direction. It uses the same four pairs in both directions at the same time.

1000Base-T uses two pairs per direction, actually. It's full duplex. Each port sees two TX and two RX pair. There are four pair of wires in the cable. If you use all of them for TX, you can't receive.

> There are four pair of wires in the cable. If you use all of them for TX, you can't receive.

No, you absolutely can use them all for transmit and receive at the same time. The device at each end knows what signal it is transmitting, and can remove that from the received signal to identify what has been transmitted by the other end.

This is the magic that made 1000Base-T win out among the candidates for Gige over copper, since it required the lowest signaling frequencies and thus would run better over existing cables.

That's not true. https://en.wikipedia.org/wiki/Gigabit_Ethernet#1000BASE%E2%8...

with most of the privatisations triggered by EU law!

I wouldn't strictly put all of them at the feet of the EU. While what you say is true, the Conservatives were frothing to privatise whatever they could. Labour just went along with the process (and I'm no Labour supporter either). The one I won't forgive was our water. I believe we're the only developed country to have privatised our water, with disastrous consequences. And that one can be squarely laid at the feet o…

100% agreed

there's no market or competition at any level (even RAIL had somewhat competitive bidding for franchises)

they're just Henry VIII style granted monopolies, with the results are the same as they were 800 years ago

(well, other than the civil war bit)

> And that one can be squarely laid at the feet of Margaret 'Fucking" Thatcher (real name).

water was another EU triggered one: the EU (EEC) kept writing new water directives, and the government couldn't figure out another way to fund their implementation

Wait, but you get 63MB/s down from steam? My internet is pretty good, I can easily saturate my (rather dated) WiFi at about 30MB/s. But Steam downloads are extremely slow for me (can't remember the numbers but much less). I always assumed Valve themselves were just stingy with bandwidth. Something else funny going on?

> Wait, but you get 63MB/s down from steam? I usually (but not always) saturate my downlink with Steam downloads... even back when I was a Comcast customer and paying for ~180MB/s (~1500mbit/s) asymmetric service. I believe that I have noticed that smaller games (~a few hundred MB or maybe a GB or two) will download quite a bit slower than large games, but I'm not very confident in that observation.

Comcast has Steam server(s) colocated within their network in my immediate area. I’ve observed that less popular downloads tend to connect to external servers in the next state over.

I think I told this story plenty of times now, but Wifi got so good, that even though we have network cables everywhere, basically nothing is hardwired in our household any more other than the TV and a few sonos speakers that were close enough to the outlets. We have about ~100 devices connected to our home network according to my router and other than 6 devices, they are all on Wifi. I would never have expected that…

I'd like to mention that the cat5e cable present in your walls is rated to 2.5Gbps, and would often still work at 5 or 10Gbps over shorter runs in a home. 2.5gb equipment is very cheap nowadays. I got a couple of no-name switches under $40 each and they all work perfectly. Wired networks will always have better consistency and latency characteristics, too, if that matters to you.

> One peculiar thing from the UK: Internet providers don’t truly offer gigabit internet. They have a range of deals like 30 Mbps – 75 Mbps – 150 Mbps – 300 Mbps – 500 Mbps – 900 Mbps, each one costing a few more pounds per month than the last. This makes the UK simultaneously one of the cheapest and one of the most expensive countries to get Internet. Andrews and Arnold[0] offer gigabit, but I'm not surprised the aut…

It's not true either. Openreach offer a 1.6gbit/sec product now, which ISPs can resell.

I don't understand why he says it's the most expensive places to get internet. You can get 900mbit (really 1gig pre overheads) for ~£30/month on openreach infrastructure which is not the cheapest in the world but it certainly isn't the most expensive.

And if you're covered by an altnet (who build their own infrastructure instead of reselling openreach) like cityfibre, community fibre or netomnia you'll get far faster speeds for even less money.

A lot of these providers do rent the poles and ducts off openreach, but then lay their own fibre over it

> Basically, you need to follow the tracking regularly until the package is tagged as lost or failed delivery, which is the cue to pay import fees. > It’s the normal procedure to buy things from Europe since Brexit 2020. It’s actually quite shocking that Royal Mail still hasn’t updated their tracking system to be able to give a status “waiting on import fees to be paid online”. They had 6 years! Wow.

> "Paid the fee online, 20% VAT + a few pounds of handling fees ... It’s the normal procedure to buy things from Europe since Brexit 2020." Why don't Amazon and other online retailers just charge you the UK VAT when you order and ship it "VAT paid", so it doesn't get held up at the border? That's how it works in New Zealand. You pay New Zealand's GST when you place an order, not after it arrives. Any online retailer…

Strangely, if I order from Amazon UK to Finland in the EU, the VAT is already all included and it comes directly to me, no customs. Even for some third party sellers too.
