South Africa Bullied by a protector
When Donald Trump returned to the US presidency in January 2025, South Africans were surprised to find themselves in his line of fire.
The false claim that white South African farmers are being murdered for their land has long been a staple conspiracy theory of the white far-right
(white farmers have been killed, but not at a higher rate than the thousands of other victims of South Africa’s high violent crime rate).
With Trump back i…
Clean drinking water gaps linked to hunger and unsafe food worldwide #environment
When they say "we are entering a new industrial revolution" what they want you to hear is "things that were once expensive will now be cheap," but what they mean is "we will be using the massive economic disruption, that we are creating, to change the world against your will and further shape it towards the interests of a small and powerful minority."

Starting to dust off the Ethernet switch project and make some strides towards finishing it.
First step: preparing to populate the back side of the remaining switch line cards. I hand assembled one a year or so ago and then the project got put on ice while I got busy with higher priority stuff.
But now that my friends are starting to get their PnP operational, I'm gonna try and run the rest of the boards on it.
Just inventoried components for the back-side assembly run …

Abstract: Reference frame mismatch among communication parties introduces errors in quantum cryptographic protocols. As the number of participants increases, aligning reference frames becomes increasingly difficult, complicating multipartite quantum cryptographic implementations. Here, we theoretically and experimentally investigate multipartite reference-frame-independent (RFI) quantum cryptographic communication using Greenberger-Horne-Zeilinger (GHZ) states. We generalize the bipartite RFI security parameter $C$ to an $N$-party parameter $C_N$ and derive the asymptotic secret key rate expressed solely in terms of experimentally accessible quantities. We analyze the key rate under global and local depolarizing noise models and find that increasing the number of parties $N$ enhances robustness against global depolarizing noise while increasing vulnerability to local channel noise. We also present a proof-of-principle experimental demonstration of four-party RFI quantum cryptographic communication using four-photon GHZ states, confirming the reference-frame invariance of both the $C_4$ parameter and the secret key rate under various reference frame rotations.

War started: line goes up. War on pause: line goes up. War resumes: line goes up. Oil prices rise: line goes up. "Peace" talks: line goes up. Talks break down, more bombing: line goes up. Thermonuclear war threats: line goes up. Ceasefire summit: line goes up. Ceasefire starts: line goes up. Ceasefire actually completely made up by the US: line goes up. Bombings continue: line goes up.
