To find startup ideas, focus on identifying a person with an unavoidable priority unmet by current options, using the PULL framework to assess demand. Instead of reliance on interviews, founders should gain firsthand experience by immersing themselves in customer environments. Validating ideas requires actual customer purchase, not just enthusiasm or analysis. Approaches include riding technological waves or improving existing solutions. The key to success is testing hypotheses through direct customer engagement and adjustment, not superficial validation with design partners.

Kyoto University researchers developed Adriana, a pain reliever comparable to morphine but with a different mechanism, potentially reducing serious side effects like addiction and respiratory issues. The drug targets norepinephrine regulation, and clinical trials showed promising results. Further US trials are planned, aiming for practical use by 2028, offering relief for cancer patients without opioid-related risks.

PHP 8.5 introduces the pipe operator (|>), allowing chaining of function calls for more readable, concise code. Inspired by Unix pipes and similar features in languages like F# and OCaml, it enables transforming complex expressions into simple pipelines. The feature can handle null safety and stream processing, with ongoing work on related RFCs like partial function application and function composition. These enhancements aim to improve PHP's functional programming capabilities, with further improvements planned for future versions.

Creates 3D line drawings by transforming images into contour or stylized line art using GANs and monocular depth estimates. Swapping these transformed images into 3D Gaussian Splatting workflows yields photorealistic or stylized 3D scenes. Variations include adding color, blending styles, object collage, and resolution adjustments. Process offers interactive, real-time rendering with adjustable styles and efficient modifications.

Passkeys are essentially passwords managed by password managers, offering anti-phishing benefits but cannot be copied or pasted easily. They require a password manager to use and are reset similarly to passwords. Switching between managers is difficult due to restrictions on copying passkeys, but future protocols may improve this. Passkeys enhance security but do not eliminate risks, and their management can complicate user authentication workflows.

The Schwartzian Transform is a caching sorting technique first posted by Randal Schwartz on Usenet in 1994, inspired by Lisp and used in Perl to improve efficiency. It gained recognition through Perl community discussions, posts, and books from the mid-1990s, eventually becoming a well-known idiom called the "Schwartzian Transform." Named after Schwartz in 1996, it is a decoration-sort-undecorate pattern for faster sorting. Variations include using hashes for caching computed keys. The technique remains influential in multiple languages and is part of Perl's idiomatic programming history.

The article describes implementing deterministic simulation testing (DST) in a new Rust database architecture using state machines. All core components are single-threaded, communicate via message passing, and are controlled by a central message bus, allowing precise manipulation of concurrency, time, randomness, and failure injection. This design simplifies debugging, enhances reproducibility, and allows comprehensive failure testing. Although it increases cognitive overhead and depends on managing dependencies, it has successfully identified critical bugs, making it a powerful approach for system correctness.

Open-source firmware for Ingenic SoC IP cameras supports various indoor, outdoor, bulb, and module cameras with specific hardware configurations. Compatibility depends on matching SoC, sensor, Wi-Fi, and flash specs. Some devices employ secure boot or secret keys, limiting modding. The project is community-driven, with potential support for additional cameras under investigation. Unsupported hardware includes battery-powered Zeratul platform cameras. Resources include a GitHub repo, wiki, and support groups.

shwim is a peer-to-peer, end-to-end encrypted terminal sharing tool that allows a host to share their terminal with a guest securely using Magic Wormhole cryptography. It runs via Python, combining tty-share's terminal sharing with Magic Wormhole's security. The host runs shwim to generate a code, which the guest uses to connect. It is intended for trusted users, as the guest can interact with the shared terminal.

A billion dollars is one thousand million, enormous and hard to visualize. Visualized as pixels, it would take billions of tiny dots to represent. It can fund a city like St. Louis for a year or a billionaire could live comfortably in America for over 11,000 years. Earning a billion dollars through minimum wage work would take about 70,000 years. It represents immense work, time, and social power, highlighting the vast difference between wealth and everyday value.

Amazon's AWS European Sovereign Cloud will be operated exclusively by EU citizens based in the EU, adhering to EU law and providing independent, sovereign cloud services for Europe's regulated industries and public sector. The initiative, supported by a €7.8 billion investment through 2040, aims to meet Europe's digital sovereignty needs by restricting operational control to EU personnel, ensuring data security, autonomy, and compliance. The transition will complete by the end of 2025, with a focus on supporting impacted employees.

Survivors of Hiroshima, including six individuals detailed in John Hersey's 1946 account, reflect on their experiences with shock, gratitude, and moral ambiguity. They lived through random chance and small decisions that spared them, yet suffered lifelong trauma, injury, radiation sickness, and loss of loved ones. Many struggled with acceptance, moral questions about the atomic bomb's use, and their changed lives, while some expressed nationalism or resigned complacency. The aftermath revealed both the horror of destruction and a fragile hope for rebuilding and understanding amidst profound suffering.
