Apple Notes Rumored to Get Markdown Support in iOS 26

Apple's Notes app is reportedly getting Markdown support in iOS 26 and macOS 26, according to 9to5Mac. This would let users format text with simple syntax, ditching the app's current rich text controls. It's a big upgrade for keyboard-centric users, letting them type **bold** or # Header directly instead of tapping buttons. This puts Apple Notes on par with Obsidian, Notion, and Bear. Developers and writers already using Markdown on GitHub or Reddit will appreciate the streamlined workflow. If true, the feature will likely be unveiled at next week's WWDC alongside other iOS 26 improvements like automatic translation and polls in Messages, and a visual redesign.

The Demise of 32-bit Support in the Linux Kernel?

2025-09-02

At the Open Source Summit Europe 2025, Arnd Bergmann, the maintainer of architecture support in the Linux kernel, delivered a talk discussing the potential removal of 32-bit system support. While desktop and server systems have long transitioned to 64-bit, a significant number of 32-bit devices remain in embedded systems. Bergmann noted that while the kernel is still adding support for some 32-bit boards, the number of 64-bit boards supported has significantly surpassed 32-bit ones. He argued that removing 32-bit support is a gradual process, requiring consideration of existing hardware and software support and analyzing user numbers to determine when to remove support for specific architectures. The talk also addressed challenges and solutions related to 32-bit support, such as high-memory support, the year-2038 problem, and big-endian support. Ultimately, Bergmann stated that the kernel will retain support for armv7 systems for at least another ten years, while support for other 32-bit architectures will likely fade away sooner.

The Shocking Secret Speech: Khrushchev's Denunciation of Stalin and its Global Impact

2025-06-21

In 1956, Nikita Khrushchev delivered a secret report, "On the Cult of Personality and Its Consequences," at the 20th Congress of the Communist Party of the Soviet Union, launching a scathing critique of Stalin's totalitarian rule and purges. The speech, leaked to the West, revealed the extent of Stalin's brutality, triggering upheaval within the Soviet Union and profoundly impacting the communist world. It sparked de-Stalinization, contributed to the Sino-Soviet split, and, through a dramatic chain of events involving Polish journalists and Israeli intelligence, ushered in a period of brief liberalization known as the Khrushchev Thaw.

Popcorn: Running Elixir in the Browser

2025-05-17

Popcorn is a novel library enabling the execution of Elixir code within web browsers. Leveraging the AtomVM runtime, it executes compiled Elixir code client-side, offering APIs for Elixir-JavaScript interaction, serialization, and communication, while ensuring browser responsiveness. Currently under development, with an unstable API, it showcases three live examples: a simple Elixir REPL, interactive tutorials, and a Game of Life implementation. Developers can start using Popcorn by adding it as a dependency in their `mix.exs` and setting up JS and Elixir WASM entry points. It connects JS and Elixir via message passing and allows direct JS execution from Elixir. The Elixir side uses the `Popcorn.Wasm` module, while the JS side uses the `Popcorn` class.

Decentralized Social Media vs. Censorship: Bluesky and the Fediverse

This essay examines how decentralized social media platforms, like Bluesky and the Fediverse, handle government censorship. Bluesky's composable moderation services allow clients to choose which services to subscribe to, but its centralized architecture makes it vulnerable to government pressure. The Fediverse, with its interconnected network of independent instances, presents a far greater challenge to censors, requiring attacks on numerous nodes for effective blockage. The author argues that decentralized architecture without single points of failure is key to censorship resistance, but ongoing improvements are needed to withstand more powerful censorship mechanisms.

Quantum Computing Bottleneck: Limitations of Cat Qubits

Recent research reveals significant limitations in quantum computing systems based on cat qubits. While exhibiting excellent performance in phase-flip error correction, these systems are highly vulnerable to bit-flip errors. A single bit-flip in any cat qubit directly causes a logical bit-flip error. Furthermore, the transmon qubits used for error correction are susceptible to both bit and phase flips, further hindering performance. Although some companies aim to reduce the number of required error-correction qubits by improving hardware qubits, this research indicates a substantial gap between current hardware capabilities and complex quantum computation. Breakthrough hardware advancements are necessary to realize the technology's potential.

Quantum Paradox Shakes Foundations of Physics

A new thought experiment challenges the foundations of quantum mechanics. The experiment, involving four agents and intricate quantum measurements, leads to contradictory results: two observers reach opposite conclusions about the same event. This suggests at least one of three fundamental assumptions is false: quantum mechanics is universal; measurements have single outcomes; and different observers' quantum predictions aren't contradictory. The experiment forces a re-evaluation of quantum interpretations like many-worlds and spontaneous collapse theories, potentially hinting at a novel understanding of reality.
