Re:If IPv4 Were Land on Friday October 30, 2026 @08:50AM (#50303177)
Yes, but 'use' rather than 'get'. If you tax land or other natural resources, people use less so there is more for everyone else. It doesn't pay to hoard or speculate.

> Reservoir volume in the US is measured in acre-inches.

Never heard of an acre-inch before, and I'd have to get out a calculator to work out how much water that actually is in pints or gallons, or how much it weighs.

The metric equivalent would be a hectare-meter or a hectare-mm. I know a hectare is 100 m x 100 m, so 10,000 m². So I instantly know that a hectare-meter is 10,000 m³ (10 ML, or 10,000 tonnes of fresh water). A hectare-mm is 10 m³ (10 kL). If my 1 ha block gets 1 mm of rain, then that's 10 kL or 10 tonnes of water. So easy i can do it in my head.

> And of course an inch is 2.4cm

2.54 cm.

Depends on what you mean by 'tech'.

Whereas IPv6 is effectively unlimited, so by Georgist principles should be free. I wonder if charging 'rent' on IPv4 addresses would be enough to get people to switch over?

We shouldn't. We should tax land and resource use.
> Strictly speaking - a battery is stored potential energy

That's its function, but that does not make any device that stores energy a 'battery'. An electric battery is specifically a battery of electrochemical cells — Franklin invented the term as analogous to an artillery battery (a collection of guns).

Calling every form of stored energy a 'battery' is just dumbing things down for the masses.

"now operational and supplying inertia to the national grid."

I wish someone would pay me to supply inertia. I'm quite good at it too.

I wish Australia had term limits for all politicians, and not just for the PM. Term limits prevents people becoming career politicians, which i think would be a good thing.
Re:Lula wins election after final votes tallied on Sunday October 25, 2026 @10:55PM (#50238521)
Indeed. It tends to reinforce a two-party system. Anyone who votes third-party gets accused of 'wasting' their vote.

Preferential/ranked choice voting allows people to vote third-party while still expressing a preference for one of the majors.

'Cholk' is not a word in either US or UK English:

Then again, 'sodder' isn't a word either, despite the US pronunciation:

i think there's a chron job that runs that when you hit puberty.

Honestly, they seem kind of lame. A chair with legs. A chair with 2 wheels. A rugged wheelchair. Great. Most people would just want their legs to work, or failing that, to be able to walk with assistance, not sit in a chair. Give them a powered exoskeleton, not a fancier wheelchair.

Some of the earlier prep work used wires, but not the final stunt.

> Objectively unilaterally assassinating other countries leaders is wrong

Why? If the leader is responsible for atrocities, then why would it be wrong to kill them? Especially if their removal would result in a more liberal leader replacing them, and not just chaos or more bloodshed.

In the case of Iran, there was no evidence of that, but as a general rule leaders should not be a protected class.

Yes it is immoral, but we are wrong to block it for that reason. Better to do it openly than behind closed doors, so we can see how barbaric they really are.

The squircles suck. 10.10–10.14 were best.
I read through that and think it's balanced and well-thought out. Especially this bit:

> You don’t need their permission if ... the people in the picture are participating in a public gathering, parade or similar event, and they are not the focus of the photo

And this bit:

> The permission can be implied: ... If everyone in the picture is smiling at the camera

It doesn't stop you taking photos in public if other people are present. You just have to take care that they are not identifiable.

Re:Anduril lands $2.9B Navy submarine shipyard contract on Wednesday October 07, 2026 @07:05AM (#49991052)
Indeed. The Ghost Shark articles says Australia is paying A$1.7 billion for 'dozens' of units, so tens of millions each. I bet they are a lot more capable than an aerial drone costing a few thousand. And much cheaper than a single crewed submarine.
Re:Anduril lands $2.9B Navy submarine shipyard contract on Wednesday October 07, 2026 @01:57AM (#49988842)
Well, this is to build "components for the Virginia-class submarine", but Anduril does also build drone subs:

Since you're already on the NYT site/app, try Pips, Tiles, and Sodoku.
What's so hard to understand? The opposition blocked the (minority) government's legislation, so people are protesting the opposition's actions. Maybe not a common occurrence, but seem's pretty straightforward to me.

Is it really? Our brains have a limited bandwidth, and there's no need of more than a small multiple of that per person.

Georgism has been mentioned many, many times in the 15 years you've been on HN. How could you not know about it?
