New LLM Jailbreak Exploits Models' Evaluation Skills

Researchers have discovered a novel LLM jailbreak technique, dubbed "Bad Likert Judge." This method leverages LLMs' ability to identify harmful content by prompting them to score such content and then requesting examples, thus generating outputs related to malware, illegal activities, harassment, and more. Tested on six state-of-the-art models across 1440 cases, the average success rate was 71.6%, reaching as high as 87.6%. The researchers recommend that maintainers of LLM applications utilize content filters to mitigate such attacks.

X's Engineering Director Abruptly Departs

Haofei Wang, X's director of engineering, has unexpectedly left the company, according to sources. Joining in July 2023, Wang was a key figure bridging Elon Musk and the engineering team. Recently, with Musk focusing on xAI and DOGE, Wang effectively led engineering and product. His departure's reason remains unclear. X recently added engineering leadership from Robinhood. X's business appears to be recovering, recently valued at $44 billion, thanks to xAI's rising profile and Musk's political influence. While Musk remains active on X, his attention is divided. Musk's 'everything app' vision, similar to WeChat, is yet to materialize, though the X Money payment platform is expected later this year.

C++ Coroutines: A Deep Dive into Customization

2025-07-13

C++ coroutines aren't a ready-to-use library like `std::vector`; they're a specification defining customization points requiring implementation by library writers. Extending the function concept, they support suspend, resume, and destroy operations. The `co_await` keyword marks a coroutine, and `Task::promise_type` customizes behavior at call, return, suspend, and resume points. The `awaiter` and `awaitable` mechanisms handle suspension and resumption, enabling resumption when dependencies are ready, providing flexible asynchronous programming.

NoDB: Processing Payments Without a Database

NoDB: Processing Payments Without a Database

Alvaro Duran's "The Payments Engineer Playbook" introduces a revolutionary approach to payment system design: processing payments without a database. He argues that the prevalence of asynchronous programming stems from the assumption of database necessity. Using event sourcing, each step in the payment process is recorded as an event, not as a persistent state. These events are temporarily stored in memory, and the system reconstructs the payment status from the event stream, eliminating the need for persistent storage. This high-performance, high-reliability approach, inspired by high-frequency trading, allows for quick recovery from outages through hot backups. The article details this concept using a payment flow example and looks toward future applications in payment systems.

Negative Carbon Emission Acetylene Production: A Breakthrough Based on Barium Looping

2025-07-22

Traditional acetylene production relies on the energy-intensive calcium carbide method, producing significant carbon dioxide and waste slag. This study proposes a novel green acetylene production process based on barium looping, using barium carbide instead of calcium carbide as an intermediate. The research finds that barium carbide formation exhibits faster kinetics, lower formation temperature, and no carbon dioxide release. Lab-scale barium recovery experiments validate the feasibility of this process, achieving negative carbon emissions. This environmentally friendly process is easily scalable and promises to be a key chemical platform for sustainable development, offering new insights into carbon-to-chemicals conversion.

Game developer Garry Newman recently posted about the wasted potential of assets from failed games. Many games, despite years of development, fail to achieve commercial success, leading to their abandonment. Newman highlights the significant amount of high-quality sound effects, models, and animations that are simply discarded. He proposes a solution: developers with unused assets from defunct projects should consider sharing them for reuse in platforms like Garry's Mod or S&box, giving these assets a new life and preventing waste.

AI-Generated Bug Reports Flood Open Source Projects

Open source maintainers are drowning in low-quality bug reports generated by AI. These reports often waste valuable time and resources, as AI systems currently lack the ability to understand code and frequently produce false or even malicious reports. Seth Larson of the Python Software Foundation and Daniel Stenberg of the Curl project have both highlighted the issue, emphasizing the strain on volunteer maintainers and the risk of overlooking genuine vulnerabilities. The problem necessitates a community-wide effort to improve funding, enhance efficiency, and develop better filtering mechanisms to identify and handle AI-generated junk reports.

Youth Reading Crisis: Enjoyment and Frequency Plummet

A 2025 literacy survey of 5-18 year-olds reveals a persistent reading crisis, with enjoyment and daily reading rates hitting 20-year lows. Only 32.7% of 8-18 year-olds reported enjoying reading, a 36% drop since 2005. Daily reading fell to 18.7%. The study found that material linked to favorite films/TV shows, matching interests, engaging covers/titles, and choice significantly impacted reading motivation. Even those reporting low enjoyment recognized reading's educational value, consuming song lyrics, news, and fiction. The report suggests aligning reading with personal interests and other media to re-engage young readers.

A common narrative claims kerosene replaced whale oil for lighting, saving whales. This article challenges that. While kerosene reduced demand for whale oil in lighting, 20th-century whaling intensified dramatically, decimating whale populations. Whale oil found extensive use in lubricants and other applications, and advanced whaling technology exacerbated the problem. Only government-enforced whaling bans and the development of synthetic alternatives truly saved the whales. This story highlights that technological progress isn't always a panacea, and government intervention is crucial in environmental protection.

Viking Hoard Reveals Surprising Trade Links Between England and the Islamic World

A Viking-Age silver hoard unearthed in Bedale, North Yorkshire, is rewriting our understanding of Viking-era trade. Analysis reveals that a significant portion of the silver, dating back to the 9th-10th centuries AD, originated not from local plunder but from the Islamic world, specifically Iran and Iraq. This silver traveled along established trade routes, reaching Scandinavia and eventually England. The discovery challenges the simplistic 'Viking raider' stereotype, highlighting the sophisticated trade networks and economic integration of Viking-Age England within a broader Eurasian economic system. The hoard's contents, including ingots, necklaces, and a sword pommel, demonstrate the Vikings' ability to refine and recast silver, blending Eastern and Western materials, showcasing cultural fusion alongside economic exchange.

GitHub: Surface-Stable Fractal Dithering

Rune Skovbo Johansen invented a novel surface-stable fractal dithering technique. This allows dither patterns in 3D scenes to stick to surfaces while maintaining approximately constant dot size and spacing on screen, even as surfaces move. This GitHub repository provides a Unity example project, shader and texture source files, and details on dither properties and global options like radial compensation and quantized layers. The technique achieves this by dynamically adding or removing dots, and offers 3D textures of varying dot densities. Licensed under MPL-2.0, encouraging community contributions.
