I read too much scifi, and almost none of it has updated on the current state of AI. For example spaceships swarming with low skill level crew members that swab the decks and replace air filters. Or depending on a single engineer to be the only one with the crucial knowledge to save the ship in an emergency.

If scifi authors aren't keeping up it's hard to expect the rest of us to. But the macro and micro economic changes implied by this technology are huge. Very little of our daily lives will be undisrupted when it propagates and saturates the culture, even with no further fundamental advances.

Can anyone recommend scifi that makes plausible projections around this tech?

Ian Banks' Culture series is the only one that comes to mind.

If not a subway at least some form of transport that won't get stuck in gridlock. Three examples I can think of are the Wuppertal suspension railway, Las Vegas monorail (though more of a tourist pull than for the locals) and the dedicated Metrobus lanes in Mexico City.

What others have I missed?

You missed Adelaide's O-Bahn, which is another way to mitigate the "buses get stuck in traffic" problem.

Sure you can.

At very low speeds, yes, the bike will fall over. But a bike with some minimum amount of speed can roll upright on its own just fine. You can try it yourself with your least favorite bike and an empty parking lot. All it takes is a good solid push. It has to do with bicycle frame geometry and center of mass.

That's not countering the argument that steering is what is preventing the bike from falling over rather than the gyroscopic effect of the wheels. You'd have to tie off the handlebars with a static line before rolling it in order to prove that it was the gyroscopic effect keeping the bike upright.

I'm curious about how direct indexing impacts tax filing. You mentioned generating short term/long term capital gains numbers, which is fine, but what about all the different transactions? Won't someone using your service have to enter all of them manually on their return?

Gh0stRAT · 8 months ago

IIRC if your brokerage reports everything to the IRS properly, you only need to fill out net short- and long-term capital gains on your schedule D rather than specifying every single transaction on a bunch of Form 8949 copies.

Not sure if Double's underlying brokerage is reporting everything necessary for this to be the case though, as I believe some brokerages don't.

Right there myself.

One conversion I want to attempt, but am unfortunately unlikely to, is an electric rear wheel drive.

Front wheel can remain gas with transmission. Add more generating current capacity, and have that dumped into the rear drive system batteries.

With my current car, the V6 gets very good economy at speed, and poor economy in town or in traffic.

An assist from the rear can tackle the poor economy cases nicely, leaving the rest to the gas engine.

Depending on battery capacity, I suppose it could do most in town driving at say 40 and below.

This is exactly how Toyota's AWD works in the Sienna these days.

It gets 35mpg city and highway, 1mpg less than the front wheel drive Sienna (which, to be fair, is also a hybrid)

> Pre-shared keys are just inconvenient to handle safely.

You can transfer PSKs safely and easily with OpenSSH 9.0 (released 2022-04-08) or later, which uses sntrup761x25519-sha512@openssh.com as the default key exchange method.

If your threat model includes someone with a quantum computer intercepting all of your traffic and storing it to decrypt later, you probably don't want to share your keys over a non-PQC channel unless you can guarantee that they haven't started eavesdropping on your traffic yet.

What track record?

Gh0stRAT · a year ago

They fought the FBI over unlocking iPhones when they could have just quietly complied with the request. I'd say they have a decent track record.

I'd bet economics. There are magic $/experiment thresholds where it becomes possible for scientists to try something, and one the threshold is crossed a bunch of people explore the same area at the same time.

Take neural nets. FLOPS/$ crosses some magic number so that universities can afford the hardware, and bam; AI everywhere. No obvious theoretical breakthroughs since the 70s, but suddenly the field gets intense due to economics.

Gh0stRAT · 2 years ago

IIRC backpropagation was a very significant breakthrough on how to update weights when training neural nets.

Is there a reason you split IoT stuff off of the guest network?

On my network we just have a guest network which denies LAN access to anything connected to it, but I'm wondering if there's a good reason to split IoT off entirely.

Gh0stRAT · 2 years ago

I want my guests to be able to cast to my TV, add songs to the Spotify queue, etc. As far as I can tell, these sorts of features work via broadcast frames and thus require the relevant devices to be on the same subnet.

Things like my printer and wifi-connected grill live on a much more restrictive VLAN. (with some firewall rules to allow devices on the trusted network to still print to my printer's hard-coded IP address)

Basic Amazon stores never used this. Only the amazon go convenience stores ever did. As far as I can tell, the former are all closed now while many of the latter are still open. At least here in Seattle.

Gh0stRAT · 2 years ago

Amazon Fresh also used it in a handful of locations. (and still does) IIRC there are 2 Whole Foods locations that use it as well.
