10 years of pomological watercolors
A decade ago today I published a blog post calling for the US government to release its paintings of fruits. The Pomological Watercolor Collection, as I had recently come to know, is a beautiful and remarkable corpus of over 7,000 pictures of fruits and other biological specimens, made between the 1880s and 1940s. Through a handful of FOIA requests I’d learned that the images had been meticulously digitized and put online for purchase, but that less than 100 pictures had been sold that way â€â€¦

It's 90 Degrees in Atlanta (32C). My dog barked when the UPS truck stopped in front of my house. I went to the fridge and got an ice cold bottle of water. When the driver rang my doorbell, I gave him the bottle and he gave me my package. I looked out a minute later as I was walking past a front window and saw him seated, about ready to drive away, chugging the water. This wasn’t my first time, but I don’t do it enough. I need to do this more often.

Die Telekom feiert 232.000 neue Glasfaser-Homes-Passed im Mai – klingt nach Fortschritt, ist aber oft nur Fassade. Wer auf den echten Hausanschluss wartet, braucht allerdings Geduld: Zwei bis drei Jahre sind keine Seltenheit – das Ziel bleibt „Homes Connected“, nicht „Homes Passed“ - #Golem ht…

Quantum-Accelerated Wireless Communications: Concepts, Connections, and Implications
Quantum computing is poised to redefine the algorithmic foundations of communication systems. While quantum superposition and entanglement enable quadratic or exponential speedups for specific problems, identifying use cases where these advantages yield engineering benefits is, however, still nontrivial. This article presents the fundamentals of quantum computing in a style familiar to the communications society, outlining the current limits of fault-tolerant quantum computing and uncovering a …

Optimal Feedback Control in Social Networks in a McKean-Vlasov-Friedkin-Johnsen System
This paper presents a comprehensive analytical formulation for deriving a closed-form optimal strategy for agents operating within a social network, modeled through a McKean-Vlasov stochastic differential equation (SDE). Each agent aims to minimize a personal dynamic cost functional that accounts for deviations from the collective opinions of others, their own past beliefs, and is influenced by randomness and inherent opinion rigidity, often described as stubbornness. To tackle this, we develop…

The crime rate in DC is lower than at any other time in the last 30 years, but with potus ordering federal agents and U.S. military into DC, he is committing crimes and directing them to do so.

A Comparative Performance Evaluation of Kyber, sntrup761, and FrodoKEM for Post-Quantum Cryptography
Post-quantum cryptography (PQC) aims to develop cryptographic algorithms that are secure against attacks from quantum computers. This paper compares the leading postquantum cryptographic algorithms, such as Kyber, sntrup761, and FrodoKEM, in terms of their security, performance, and real-world applicability. The review highlights the strengths and weaknesses of each algorithm and provides insights into future research directions. We also discuss the challenges of transitioning from classical to…
