That might be true in some places, but in Europe for example there really isn't that much room left. And moving large quantities of electricity from a desert to a place where people actually use it is also a challenge

It is said that the infrastructure required to sustain suburbs costs more money than these suburbs bring in. In the US a city gets federal money to build new suburbs, but when it comes to renewing them after a few decades, the city has to pay on its own and it often has not enough money to do it.
I am by no means an expert on this topic and just poorly summarized the contents of this video: https://youtube.com/watch?v=7IsMeKl-Sv0

on: Dora: A open-source Rust DHCP Server
On IPv6 this would be a solved issue. With SLAAC the router just broadcasts Router Advertisements and all the machines just automatically configure their addresses, which are fully predictable based on their MAC address (if you have privacy extensions disabled). The router has no state to keep and as such the network can be scaled up "infinitely". Just pick a random /64 prefix and set up radvd (or systemd-networkd) to send the router advertisements.

on: An unconfirmed tweet about Freeport LNG is upending gas markets
People are saying this because so far it has just been much warmer than usual at this time of year, and snow in November wouldn't be the most unusual thing, and most people just assume snow=winter.
Some stats of my weather station in South Germany from this year and last year. It is much warmer this year, and even last year was pretty warm
Oct 2021: Avg: 8.5°C Min: 0.5°C Max: 22.0°C
Oct 2022: Avg: 12.7°C Min: 4.9°C Max: 21.5°C
Nov (1st to end of 11th) 2021: Avg: 4.1°C Min: -1.9°C Max: 9.4°C
Nov (1st to end of 11th) 2022: Avg: 7.8°C Min: 0.9°C Max: 15.8°C
I have no clue about weather forecasting and I can't exclude a drastic change in the coming months, but right now it just doesn't look like that at all

You either do an interview or a member sends you an invite. It's a private tracker just like what.cd was. It's less elitist than most other trackers which are invite only and sometimes lock registrations completely. Unfortunately they have to keep a low profile and pick their members to avoid copyright trolls or being shut down entirely. The test isn't very difficult and there is a public page explaining everything one needs to know. It's more about showing some effort and making sure that you know how to act accordingly on a private tracker

Well, clearly they sent it to you, so they're distributing the images. The E-Mail headers, especially if they contain a dkim signature, are likely sufficient proof for that. If not, the provider they used might be able to back your claims up. If you were using some E-Mail provider instead, those images would still land on your client devices, and the situation would be almost the same. And of course let a lawyer do the talking

Yeah in rural areas it's hard to justify building public transport. Villages can still have grocery stores though. But we were talking about cities here

Shopping would optimally happen by foot or by bike. Somewhat impossible with US zoning laws, but in a decent mixed use neighborhood a grocery store would be a <5 minutes walk from home, with actual sidewalks and no highways in between.
And overcrowded buses happen in underfunded bus systems with not enough capacity or on peak times. Consider increasing the frequency or upgrading to a tram line if your buses are always full

Inner city driving should be restricted to service vehicles only. The inner city should be dense enough that shopping is easily done by foot or by bike, and things further away are covered by a tram or bus line within walking distance

on: Ask HN: Is Public WiFi Dangerous?
Exactly. A commonly missed attack vector is just intercepting plaintext http and blocking https, so the browser thinks the site doesn't offer https and will just continue in plaintext. The same criticism applies to smtp using starttls, an attacker can suppress the starttls command and the default is to just continue in plaintext.
This is why an https only mode is important. In Firefox it can be enabled somewhere in the settings.

on: IP Addressing in 2021
It allows for tracking users since the second half of your address is always constant. It's a fixed problem though since basically all consumer devices these days use privacy extension addresses, which don't expose your MAC address and periodically change to a new random IP address
