This is the third full build iteration of my miniature #QRP unun supporting both EFHW and "random wire" antennas. At this point, it is still fiddly to build, but I'd expect an experienced #HamRadio DIY / homebrew enthusiast to find the build not terribly difficult.
There's nothing…

Exponential Quantum Advantage for Message Complexity in Distributed Algorithms
We investigate how much quantum distributed algorithms can outperform classical distributed algorithms with respect to the message complexity (the overall amount of communication used by the algorithm). Recently, Dufoulon, Magniez and Pandurangan (PODC 2025) have shown a polynomial quantum advantage for several tasks such as leader election and agreement. In this paper, we show an exponential quantum advantage for a fundamental task: routing information between two specified nodes of a network.…

FCT O-RAN: Design and Deployment of a Multi-Vendor End-to-End Private 5G Testbed
The transformation of 5G networks into software-defined, agile, intelligent and programmable architectures necessitates a paradigm shift in deployment strategies. To deliver superior performance and surpass traditional systems, public and private 5G networks must adopt software-centric cloud native frameworks that enable flexibility through tailored configurations and optimized deployment approaches. In Singapore, the Infocomm Media Development Authority (IMDA) and the National Research Foundat…

Google has teased 60-second AI videos from Veo, which sounds impressive until you realize that requires not 10x, but 100x the energy of a 6-second clip.

While the US can protect security in Europe and deserves our undying gratitude for having done so for the last 80 years,
Europeans cannot protect democracy in the US.
They can and must, however, protect liberal democracy in Europe,
which risks becoming a collateral victim of Trump’s domestic and foreign policy agenda.
What happens in America doesn’t stay in America.
It is often a precursor for trends in Europe.

Great that Mr Rauch is now "Optimistic for Peace, safety and greatness for Israel and its neighbors". People in Gaza will be very happy.
You still deploying all your shit to Vercel and using their software stack?

Revealing the Power of Post-Training for Small Language Models via Knowledge Distillation
The rapid advancement of large language models (LLMs) has significantly advanced the capabilities of artificial intelligence across various domains. However, their massive scale and high computational costs render them unsuitable for direct deployment in resource-constrained edge environments. This creates a critical need for high-performance small models that can operate efficiently at the edge. Yet, after pre-training alone, these smaller models often fail to meet the performance requirements…

CCAT: Mod-Cam Readout Overview and Flexible Stripline Performance
The CCAT Observatory's first-light and commissioning instrument, Mod-Cam, is nearing readiness for deployment to the Fred Young Submillimeter Telescope (FYST) in the Atacama Desert in northern Chile. In-lab testing of Mod-Cam and the first CCAT instrument module, a 280 GHz broadband camera fielding over 10,000 kinetic inductance detectors (KIDs), is currently underway. CCAT's first-generation science instrument, Prime-Cam, will field approximately 100,000 KIDs across seven instrument modules. L…

CCAT: Mod-Cam Cryogenic Performance and its Impact on 280 GHz KID Array Noise
The CCAT Observatory's Fred Young Submillimeter Telescope (FYST) is designed to observe submillimeter astronomical signals with high precision, using receivers fielding state-of-the-art kinetic inductance detector (KID) arrays. Mod-Cam, a first-light instrument for FYST, serves as a testbed for instrument module characterization, including detailed evaluation of thermal behavior under operating conditions prior to deploying modules in the larger Prime-Cam instrument. Prime-Cam is a first genera…
