Comment Re:"Powerful" quantum computer (Score 1) 74

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.

Comment Re:How do I quantum vide code? (Score 1) 74

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

Frankly, the quality of build, the stability of the operating system, and just the plain reliability and features even in the supporting tools exceed Windows. Take the Preview App. The work I can do on PDFs; signatures, annotations, OCR, right out of the box, and built so that the versions on my iPhone and iPad fully integrate, cannot be easily replicated on Windows. Apple just really has an eye for workflow, and making sure the base system and tools fit well into that.

It's not perfect, to be sure, I wouldn't want to use Pages as my full time word processor, and Apple, like Microsoft and Google, suffer designed interoperation friction, which does suck. But all in all, I'm just more efficient on a Mac, and in subtle ways I never knew were even problems until I picked a MacBook up the first time. Honestly going to Windows right now is just horrible for me, particular Windows 11, which just feels like constant chaos and out of control busy-ness.

Actually, at the extreme scales, which is the total volume of the observable universe, the universe is quite homogeneous. As I recall, to the order of 1-in-10000 variance. This is why Inflationary cosmology was developed, to explain the distinct lack of lumpiness in the universe, which is what we would expect if the Big Bang alone were responsible.

Well, first of all, hydrogen is the most common element in the universe, and carbon makes up something like 0.5% of the total observed mass of the universe (it's the fourth most common element), so along with other trace elements like sodium, phosphorus and the like, we're simply looking for places where there is sufficient energy to create the necessary reactions to produce organic compounds. No lack of energetic sources, in particular stellar system formation. Indeed many comets and asteroids host a lot of precursors, indicating that some fairly sophisticated organic chemistry was going on early in the solar system's development.

Panspermia would require that life itself was raining down on the terrestrial planets. Precursors would simply indicate there were a lot of strange and complex organic compounds falling on to the surfaces of planets like Earth, Mars and Venus, and were also likely constituents of bodies like Europa and Titan (well, we know Titan is covered in a literal hydrocarbon stew). What this discovery indicates, at the very least, is there was indeed a lot of organic compound in the early solar system and these organic compounds, at least on Earth, led to abiogenesis. Panspermia would advocate abiogenesis happened at some undetermined point further back.

If we find other life in the solar system, such as in Europa's or Ganymede's oceans, and it has DNA or some very close relative, with similar translation and transcription systems as we find in archaea and bacteria on Earth, then that would be a very strong argument that life in the solar system had a common origin. If however, there is no clear relationship between the two populations; say, they use something similar to DNA, but the genetic codes are different (all extant life on Earth uses the same canonical genetic code mapping codons to amino acids, strongly suggested the canonical code evolved prior to the Last Universal Common Ancestor), then we're very likely looking at an example of convergent evolution, and not in fact at two related populations.

To me the hoops that smoothbrains will jump through to avoid IPv6 and stay on legacy IPv4, especially when hosting, is pathetic. NAT, port forwarding, tunnels, blah blah blah blah.

I have something like ~1.2 trillion times the number of routable addresses that the entire IPv4 space has. Not all are reachable, of course, just the services that need incoming access and they're each on their own isolated DMZ.

Comment My home network is nearly pure IPv6 (Score 1) 73

Started the move about 18 months ago when I decided to get off my lazy ass. My ISP gives out a /56 prefix, so that lets me run 256 /64 subnets/VLANs in the house, currently there are ~10 in use. Everything get a GUA through SLAAC and I use RAs (Router Advertisements) to give ULAs to everything. Any external facing services get their own VLAN and /64 for the system(s) as needed. Firewall blocks all incoming as they usually do by default and I punch a hole for the external-facing systems. They can't reach back into the network, they only answer the phone. All the systems update DNS dynamically if the prefix or full address ever change.

I have an SSH bastion set up. In all this time there has not been a single SSH attempt from the internet. On IPv4 it was constant background noice.
For those legacy IPv4-only systems on the internet, I set up NAT64. I have an IoT VLAN and IoT 2.4 GHz wireless network that are only IPv4 because a lot of IoT network stacks are junk.

I'm still farting around with it, but man oh man, there's no way I'd go back to IPv4. It was one of the best moves I've done in ages.
