"The advertised 97% round-trip efficiency is a joke."

Is it? You haven't provided numbers that say one way or another.

Your equipment is on full-time and has operating costs associated with it, your numbers work out to be about $10/month where I live. Concerning at my really low energy cost. It would be $50 a month for my sister, a cost she'd had to further recover with solar. Imagine paying that monthly for the mere presence of backup capability, not the purchase or maintenance costs.

But your "total discharge energy" what is that? If a battery backup is never activated is there any discharge energy? Round trip efficiency needs to be determined with appropriate data, that would be the total energy required to discharge that 4.5MWh, not the parasitic losses for when discharge isn't occurring.

Because the priorities of society have shifted from supporting the quality of life for people like you to enabling exploitation of people like you. Forcing you to think that backup batteries are necessary for basic life functions is part of that exploitation, batteries aren't the solution, fixing the priorities is.

What does home battery installation do to decrease CO2 emissions?

Never underestimate the cost of a station wagon full of kilowatts hurtling down the highway.

Here the payback is never though.

Centralized generation should be more cost effective. The fact that a failure of capitalism causes decentralization to make sense doesn't justify decentralization, it justifies fixing corporate greed.

"You can even DIY your own battery cheaper than you can buy one..."

Sure, if you don't care about safety or insurance.

I can have the equipment, installed in my home, for no more than $1000, still can't find an economic case for it.

>"The matter is somewhat urgent," The Register reports, because a court-ordered support arrangement expires August 3, "so T-Mobile may soon be unable to get support for its very substantial VMware estate." ... The carrier fired back by pointing out that it has made just two support calls in 2026, which hardly justifies such a massive staff and expense.

They have a perpetual license, so can keep running VMWare without support. If they only had 2 support calls in the last year, it seems they should be able to move on to another solution without any urgent need for support. If they make a breaking change to a system, move that to the new platform. For the other existing stuff, keep calm and carry on.

I already have a mommy. I don't need another one.

>the company said its new chips will deliver up to 50% higher performance at the same power, or up to 70% lower power for the same performance.

>IBM's VP of silicon technology R&D says the new innovation "can improve performance by 50% compared to the best available chip today, and at the same time can reduce power by 70%."

One of these things is not like the other.

"Almost as stupid as believing funding in the hands of Democrats isn’t the braindead move."
Except not at all. Just another "both sides" excuse by ignoramuses and bots.

"Lets jump on Californias..."
California has problems like everywhere, but California is remarkably successful by any measure, definitely not "fucked under Democrats".

"I’m certain the imaginary kids there know all about climate change. Like the homeless know how to sign a mail-in ballot."
And this is who you really are.

"With the global climatology science no longer relying on support and funding from one of the worst sources of pollution and environmental damage..."

What an ignorant take. One could easily dispute that the totality of the American economy is "one of the worst sources of pollution and environmental damage", but the US government is NOT the totality of the American economy.

I've actually programmed quantum computers, and I have to admit this is correct. We have access to more qubits now than we can effectively use because of the rapid accumulation of noise and decoherence in quantum processing. No one seems to have achieved much with Quantum Error Correction, and schemes to get it to work better (like Cat qubits) remain theoretical.

There might be a breakthrough someday, and when it happens everyone will know quickly, but there is still a lot of work to do to get there. Or there may never be a breakthrough.

I just asked Google in AI mode "qiskit bell state" and it gave me the code.

from qiskit import QuantumCircuit
from qiskit.quantum_info import Statevector
from qiskit.visualization import plot_histogram

# 1. Create a quantum circuit with 2 qubits and 2 classical bits
qc = QuantumCircuit(2, 2)

# 2. Apply a Hadamard gate to qubit 0 to create a superposition
qc.h(0)

# 3. Apply a CNOT gate with qubit 0 as control and qubit 1 as target
qc.cx(0, 1)

# 4. (Optional) View the ideal quantum statevector before measurement
state = Statevector.from_instruction(qc)
print("Statevector:\n", state)

# 5. Measure both qubits into the classical bits
qc.measure([0, 1], [0, 1])

# 6. Draw the circuit text representation
print("\nCircuit Diagram:")
print(qc.draw(output="text"))

You can go run it on IBM Quantum Platform or AWS Braket

How do you know it's generative AI?

This article links to another article, published presumably for profit, which links to an article that requires a subscription. It's just business promotion for a /. member, there's no information here or anything to discuss.

"Obviously, using a tool outside of what it can do well will usually do more damage than good."

What does the tool do well? We don't know, we haven't been told anything about the tool. And what damage or good can it do? An AI can do no damage unless it's wired to do damage. AI is just software, completely deterministic. Can Excel do damage? Even when used to do things it doesn't do well? The threat of AI is the people who try to exploit something poorly designed to do things they don't understand. So what if AI hallucinates, the possibility of harm doesn't come from AI, it comes from using its outputs to do harm.

...is that after reading the scrolls we can confirm what we already knew, that these people were stunningly ignorant by today's standards. They don't have anything to say to us.

Part of Peter Thiel's plan. Replacing the government with a dictator won't matter if he doesn't have something to do, or murderous robots to do it with.

It's not stealing if the owner is decreased, right?
