What is the origin of the lake tank image that has become a meme? (2021)

New research indicates a potential link between specific gut bacteria and the development of type 2 diabetes. Variations in gut microbiome composition were observed in individuals with the condition compared to healthy controls.

The study suggests that certain bacterial species may contribute to impaired glucose metabolism and insulin resistance, key features of type 2 diabetes. Further investigation is needed to confirm these findings and explore potential therapeutic implications.

Scientists are exploring the possibility of manipulating the gut microbiome through dietary changes or other interventions as a preventative or treatment strategy for type 2 diabetes. This research is still in its early stages.

Bluesky is ushering in a pick-your-own algorithm era of social media

Bluesky, a social network offering granular control over content visibility, has surpassed 20 million users. This surge follows dissatisfaction with Elon Musk's changes to X (formerly Twitter).

The platform's appeal lies in its avoidance of hate speech and explicit content, but more importantly, its 'marketplace of algorithms' approach. Users can choose between various algorithms to curate their feeds, contrasting with X's more restrictive 'For you' feed.

Bluesky provides both a chronological and algorithmically-filtered feed, and other customization features. While some aspects need improvement, it offers a user-centric model where individuals, not corporations, control their experience. Its growth suggests a potential paradigm shift in social media.

How good are American roads?

US interstate highways are generally of high quality, while roads in major cities often show significant deterioration. Data suggests that interstates are comparable to or better than major roads in several other countries, but more comprehensive international data is needed for a robust comparison.

A significant portion of non-interstate roads, especially in urban areas, are rated as poor or very poor. Urban roads consistently show lower quality than rural roads, likely due to higher traffic volume. Available data represents only a fraction of the total US road network.

While US interstates perform well compared to international counterparts, non-interstate roads lag behind. Differences in road construction materials and maintenance practices may also contribute to the observed discrepancies. More research is needed to fully understand these international differences.

GNU Artanis 1.0.0 Released

GNU Artanis, a web application framework written in Guile Scheme, reached version 1.0.0. Initially inspired by Ruby on Rails and Sinatra, it has evolved its own unique features, notably a pure-Scheme, high-performance server core. The 1.0 release signifies a mature architecture after extensive testing.

Version 1.0.0 includes significant changes. Third-party libraries have been removed for cleaner code and user control over versions. Improvements focus on Guix compatibility, eliminating issues with temporary files in immutable paths. A new self-hosted website, built with org-mode, replaces the old GitHub Pages system.

The software is downloadable from the official GNU site. Documentation is available online and the development team encourages users to report issues via GitLab or email. Support is provided through manuals and community help.

Show HN: Unbug – Rust macros for programmatically invoking breakpoints

Unbug, a new Rust tool, lets developers programmatically trigger breakpoints. It's inspired by Unreal Engine and uses macros for easier debugging.

Currently needing the nightly Rust compiler, Unbug offers a no_std support option and optional log messages in version 0.2. A production build does not require nightly.

The project's creator notes that its reliance on core_intrinsics requires nightly Rust for development, but a production build is not affected by this dependency.

Using gRPC for (local) inter-process communication – F. Werner's Research Page

The article discusses using gRPC for inter-process communication (IPC) within a single machine, despite it being a full-featured RPC framework. It argues that if RPCs are already used for public APIs or a schema-based serialization layer is beneficial, using gRPC for IPC simplifies the system.

The FlashCam software architecture is described as a collection of processes, each handling a subsystem. These subsystems communicate to stabilize the camera and provide an external interface. Telemetry is sent to a collector for later analysis, offering centralized monitoring.

gRPC's latency overhead for local IPC is measured and found acceptable, despite being roughly ten times slower than basic Unix domain socket communication. The advantages of consistent, compile-time checked interfaces outweigh the performance differences for this application.

The Rise of Malört, an Unexpected Midwest Princess

Malört, a bitter Chicago-based liquor, is gaining popularity nationwide, expanding from its Illinois origins to 33 states. Its distinctive, intensely bitter taste, initially viewed as an acquired taste, has become a regional symbol and a conversation starter among Midwesterners.

Bartenders initially adopted Malört as a symbol of industry insider status, appreciating its relatively low alcohol content. However, its expansion beyond Chicago is causing concern among some purists that the drink's local identity is being lost.

Despite concerns over losing its regional appeal, Malört maintains its status as a unique conversation piece, even in bars outside the Midwest. Its intense flavor and tradition of initiation shots foster a sense of community and intrigue, setting it apart from the mainstream cocktail scene.

Show HN: Cardo ‒ Open Source desktop podcast client

Cardo is a new podcast app for desktop computers. It's designed to be lightweight and fast, aiming for a streamlined listening experience.

Users can sync their podcasts via Nextcloud or gPodder. The application is open-source and available for various operating systems.

Downloads are available as MSI, EXE, DMG (Intel and Silicon), AppImage, DEB, and RPM packages, catering to a wide range of users.

Britain is building one of the world’s most expensive railways

The UK is set to invest heavily in the HS2 high-speed railway project, which aims to connect London with major cities in the north. The project has faced criticism over its escalating costs and environmental impact, with estimates now reaching over £100 billion.

Supporters argue that HS2 will boost the economy by improving transport links and reducing travel times. However, opponents highlight the disruption caused by construction and question the necessity of such a large investment in rail infrastructure.

As the project progresses, the government is under pressure to justify the expenses and ensure that the benefits are realized for the public. The future of HS2 remains a contentious topic in British transport policy.

Ensō: design constraints of a focussed writing tool

A design document outlines goals for a writing app called Ensō. Immediate writing access via app icon is key, prioritizing privacy and a minimalist user experience.

Updates should streamline the app, not add complexity. Personalization is encouraged, avoiding decision fatigue. The app's design aims for a simple, almost playful feel.

Alternative design focuses on minimizing distractions and prioritizing personalization over features. Accessibility and visual appeal are additional priorities.
