I made memory from scratch – polymatt [video]

The video documents the process of building a memory device from scratch, covering the construction of core memory using ferrite cores and copper wire, as well as related concepts like decoders and sense amplifiers.

Background

- This video documents the process of building a simple computer memory cell from discrete electronic components (transistors, resistors, LEDs) — essentially recreating the basic SRAM (static random-access memory) bit from scratch. - "Polymatt" is a YouTube creator known for hands-on electronics and computing projects, often building primitive versions of modern technology to show how it fundamentally works. - The video demonstrates a flip-flop circuit: the core building block that can store a single binary digit (0 or 1). Most people use memory chips without ever seeing the circuitry inside; this video makes that invisible layer visible. - It bridges a common gap: many programmers and tech enthusiasts understand memory abstractly (as addresses and values) but have never seen the physical logic gates that make it possible.

Max Weinbach says he had early access to OpenAI's new model GPT-5.6 Sol, calling it his favorite model by far. He highlights that it never gives up and will keep reasoning until it's done. OpenAI announced that GPT-5.6 Sol, along with Terra and Luna, will launch publicly on Thursday, with preview access expanding globally now.
Statement on the US government directive to suspend access to Fable 5 and Mythos 5

The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 models for all customers, citing a potential jailbreak technique that involved asking the model to review a codebase for vulnerabilities—a capability Anthropic says is available in other public models. Access was abruptly cut off on June 12.

Andrej Karpathy announces the release of Claude Fable 5, the same underlying model as Mythos but with added safeguards. He calls it a major step forward, particularly for long problem-solving sessions on difficult tasks, and describes it as state-of-the-art on nearly all benchmarks with exceptional performance in software engineering, research, and vision.

Roman Storm warns that the legal theory in his case could set a precedent making open-source developers liable for how others use their code, potentially criminalizing the mere publication of privacy, messaging, or crypto tools. He notes that developer Michael Lewellen cannot publish lawful code due to prosecution fears, and argues this chilling effect extends beyond any single case.

Meta's engineering culture is deteriorating under Mark Zuckerberg and Scale AI CEO Alexandr Wang, who have introduced keyboard tracking, reassignments to data labeling, and AI-centric performance metrics. Critics argue this incentivizes performative AI use, drives away experienced engineers, and contributed to a major Instagram hijacking incident caused by AI-written and AI-reviewed code.
