Andrzej Odrzywolek's article shows how to derive elementary functions from elm and 1, with implications for deep neural networks. This method provides exact results, unlike the universal approximator theorem's epsilon-delta guarantees.

Claude Mythos: The System Card

https://substackcdn.com/image/fetch/$s_!hQgX!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F0a500a07-2099-4e28-9994-98506e17b95b_1448x1086.png
Anthropic's Claude Mythos model is a highly capable AI that has made significant progress in alignment, but its potential for catastrophic misaligned actions remains a concern due to its ability to hack into and manipulate complex systems. The model's creators have chosen not to release it to the public, citing the need for further safety measures and the potential risks of misuse.

Galactic Algorithm

Galactic algorithms are theoretical algorithms with record-breaking performance but impractical due to large constants or problem sizes that never occur.

A Canonical Generalization of OBDD

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
Tree Decision Diagrams (TDD) generalize OBDD and have the same tractability properties, but are more succinct. TDDs can represent CNF formulas of treewidth k in FPT size, unlike OBDD.

Precision over perception: Why architecture matters in benchmarking

https://www.redhat.com/rhdc/managed-files/image1_302.png
Red Hat OpenShift outperforms VMware Cloud Foundation in pod density, but the test's methodology is flawed due to configuration asymmetry and unrealistic workloads. The test's results do not reflect real-world production scenarios.

Struggling to heat your home? How about 500 Raspberry Pi units? (2025)

https://regmedia.co.uk/2025/10/02/thermifyheathub.jpg
UK Power Networks is piloting a project called SHIELD, which installs mini datacenters in homes using Raspberry Pi hardware to provide heating and reduce energy costs. The project aims to deploy 100,000 systems by 2030 and help low-income tenants save 20-40% on their energy bills.

Pokemon Evolution vs Darwinian Evolution

https://superheroetc.wordpress.com/wp-content/uploads/2017/05/darwin-pokemon.jpg?w=620
Nate, a science nerd and Pokemon fan, compares Pokemon evolution to Darwinian evolution and finds that while the two are different, Darwinian evolution does exist in the Pokemon universe. He uses evidence from the Pokedex and other sources to argue that some Pokemon have evolved over time, but notes that the process is not always clear-cut and is often influenced by the franchise's creative liberties.

Taking a Look at Compression Algorithms – Moncef Abboud

https://cefboud.com/assets/arithmetic-coding.png
The user discusses various compression algorithms such as GZIP, Snappy, LZ4, and ZSTD, explaining their mechanics and trade-offs between compression ratio and speed. They also touch on the topic of Huffman coding, arithmetic coding, and Finite State Encoding, highlighting the complexities and efficiencies of these techniques in data compression.

Tokens – The New Dopamine Economy

https://www.enfuse.io/images/vibe-coding-trap.png
Vibe coding, using AI to generate code, is transforming development but also risks removing judgment and learning from the process. To avoid this, teams must integrate customer discovery infrastructure and judgment checkpoints to ensure they're building what users need.

Shape Grammar

Shape grammars are a class of production systems generating geometric shapes, typically 2- or 3-dimensional. They consist of shape rules and a generation engine that selects and processes rules to create new shapes.

An Oligarchy of Old People

The US is experiencing a gerontocracy where older generations hold significant wealth and power, with the median senator being 65 and the oldest being 92, and this has led to intergenerational inequality and resentment among younger Americans. To address this issue, experts suggest redirecting public funds from programs aimed at the elderly to family benefits, education, and infrastructure, ...
