Not from what I've seen. The desirable neighborhoods are 500-600k. Suburbs outside major city
Desirable neighborhoods are by definition expensive. The trick is to find a neighborhood you like where your home can just be a home and not a top-heavy investment. Acknowledging this isn’t always easy or possible, but just pointing out that this is a self reinforcing problem.
Why do people seem to think that optimization is something you only have to deal with once the software scales so much that 100s of TB of memory or disk space (or thousands of hours of processing time) are being wasted. It is almost like nobody even thought during the design phase about what might happen down the road. This is why so much software is bloated and often buggy. Just gets something that half-way works ou…
Assume a sorting algorithm as a metaphor for your whole program.
You make it work by implementing the simplest thing you know how to write: bubble sort. Works.
At the end you notice it's way too slow and replace with something much better: quicksort.
Now, how much of your program is surviving? Almost nothing, perhaps except for the "greater than" comparison.
If you apply that idea to a real world program, we're pretty much talking about a full rewrite.
This is the right way to deliver software. Produce working product first, validate the idea, stabilize the business, start generating profit, and then you can start optimizing your costs. In fact optimization is by far the easiest part of the process because there are many system programming experts on this HN thread who consider these optimizations to be trivial.

Or optimize a bit earlier and prevent having to scale out to a bazillion systems.
Remember that everything has an opportunity cost. Running a lot of servers might cost $10 million annually, but if the product team had to choose between a project that would recoup $5 million of that vs. an opportunity to earn $50 million ARR for the same amount of work, the logical answer would be obvious.
Better performance = saving money + better user experience.

When I was first getting into software dev, I thought 'enterprise' meant 'industrial grade', 'powerful', 'high-performing'. Then I actually met some enterprise software, and realised that it means 'expensive', 'bespoke', 'one-off', and usually 'janky'.
Enterprise means it has SSO and a support contract

Not if the whole thing is architected poorly but was a requirement of the hour so it became big. Then optimisation becomes an art, but definitely not the ‘easiest part of the process’
I've run into issues with using public wifi when I override my MacBook's DNS server to 1.1.1.1 or 8.8.8.8. I believe this is because captive portals require custom resolution of the name captive.apple.com. And external DNS servers will not resolve that correctly to the local gateway's authorization page.
Dumb captive portals, which do still exist in some places, usually do MitM attacks on the connection, so you need some http(no-s) site that you can abuse as "yeah, this can get attacked by the WiFi" to then answer the portal. The right way is that there's DHCP option for the network to signal "I have a captive portal", that's been standardized for over a decade. … or … IDK … just stop shoving ads down people's throat…
