Connecting an ASR33 Teletype to an ESP32
As you know, I now have a working ASR33 teletype (see here for notes on restoration). Even though a few more bits to do, notable the case, ...

fly_hemibrain: Fly hemibrain (2020)
A synaptic map of the hemibrain connectome of fruit fly Drosophila melanogaster. Nodes are neurons, and edges are synaptic connections, traced individually from brain image sections using EM reconstruction techniques. Neurons are labeled by their type. Edges are annotated by the connection strength between the neurons.
This network has 21739 nodes and 4259624 edges.

Fascinating: Andrzej Odrzywołek claims in a recent preprint that all constants, operators, and functions typically found in a scientific calculator can be decomposed into nested invocations of the eml function and the constant 1, where
eml(𝑥,𝑦) = exp(𝑥) − ln(𝑦).

All elementary functions from a single binary operator
A single two-input gate suffices for all of Boolean logic in digital hardware. No comparable primitive has been known for continuous mathematics: computing elementary functions such as sin, cos, sqrt, and log has always required multiple distinct operations. Here I show that a single binary operator, eml(x,y)=exp(x)-ln(y), together with the constant 1, generates the standard repertoire of a scientific calculator. This includes constants such as e, pi, and i; arithmetic operations including addi…

Cowboys Coaching Connections Could Shape the 2026 NFL Draft https://insidethestar.com/cowboys-coaching-connections-could-shape-the-2026-nfl-draft

🇯🇴 Last week, GÉANT was in Jordan connecting with partners through #EUMEDplus project, including ASREN, SESAME Synchrotron-light, JUNet and the EU in Jordan.
A visit to SESAME highlighted how critical high-capacity R&E connectivity is for international scientific collaboration and data-intensive research.
Discussions also focused on strengthening national and cross-border connect…

“President Trump exhibits what forensic mental health experts have, across dozens of independent assessments, identified as the ‘Dark Triad’ of personality traits: narcissism, Machiavellianism, and psychopathy … Rather than constituting a clinical diagnosis, this trait-based assessment is grounded in behavioral observation and is particularly useful for assessing the level of danger an individual poses in a political leadership position. We do not offer this as a clinical verdict. We offer i…

psi: Plant Photosystem I excitation energy transfer network (2020)
Weighted directed network of the light-harvesting Photosystem Ι (PSI) of the plant Pisum sativum. The nodes represent chromophores with different identities (i.e. chlorophyll a, chlorophyll b, β-carotene and derivates, lutein, violaxanthin), while edges represent FRET transfer between chromophores. The link directionality connecting nodes in the PSI network depends on the energy levels of the connected chromophores. The…
