PgDog: A Clever Postgres Proxy for Sharding

PgDog is a network proxy that intercepts all communication between Postgres clients and servers, understands SQL to infer query destinations, and requires no application code changes. It parses SQL queries, extracts sharding keys, uses Postgres's built-in partitioning hash function, and routes queries to the correct database shard. The article details how PgDog handles simple and extended protocols, cross-shard queries, and distributed COPY operations, ultimately enabling Postgres sharding and linearly scaling data ingestion speed.

Running Linux in a PDF: A RISC-V Emulator in Your Browser

Developer @ading2210 has achieved the remarkable feat of running a Linux system inside a PDF file. Leveraging the Javascript engine within PDFs and an asm.js compiled version of the TinyEMU RISC-V emulator, a functional Linux environment is created. Output is displayed using ASCII characters, and input is managed through a virtual keyboard. While boot times are slow (30-60 seconds), the project showcases the surprising capabilities of the PDF format. The code is open-source and supports both 32-bit and 64-bit systems.

UA Engineer Develops Novel Plastic Recycling Process

Dr. Jason Bara and his team at the University of Alabama have pioneered a new plastic recycling process using imidazole. This method effectively breaks down polyethylene terephthalate (PET) and polyurethane, overcoming limitations of traditional chemical recycling. Imidazole acts as a reagent without needing additional solvents or catalysts, offering cost-effectiveness and producing valuable chemical intermediates. The technology promises to significantly improve plastic recycling rates, particularly for challenging materials like polyurethane foams found in packaging, car seats, and more, contributing significantly to environmental sustainability.

Perplexity Overtakes Google as the Top Search Engine

A veteran tech columnist recounts the evolution of search engines, from early pioneers like AltaVista to Google's dominance, and now the rise of AI-powered search. The article argues that Google's over-reliance on ads has degraded search quality, while Perplexity, with its AI-driven approach, provision of source links, and focus on user experience, has emerged as a superior alternative. While acknowledging the imperfections of AI answers, the author highlights Perplexity's verifiable sources as a key differentiator, delivering more accurate and reliable search results. Google's future is uncertain, and its ability to regain its former glory remains to be seen.

Pre-Viking Industrial Whaling? Game Pieces Reveal Early Norse Trade

Archaeologists have unearthed ancient game pieces—hnefatafl, similar to chess—made from whale bone at Vendel Culture sites in Sweden. Genetic analysis and archaeological evidence reveal the whale bones weren't from stranded whales, but from organized whaling, potentially the earliest evidence of industrial whaling in Scandinavia, dating back to 550-793 CE. This discovery reveals extensive trade networks and coastal resource use predating the Viking Age, laying the groundwork for later Viking expansion.

Supersolidity Achieved in a Photonic Crystal: A Breakthrough

2025-03-11

An international team has for the first time observed a supersolid phase in a photonic crystal polariton condensate, published in Nature. This groundbreaking research introduces a new platform for exploring supersolidity beyond traditional ultracold atomic systems. Supersolids uniquely combine the rigidity of a crystal with the frictionless flow of a superfluid. The researchers achieved this by condensing polaritons within a photonic crystal waveguide, enabling precise measurement of density modulations and probing the local coherence of the supersolid wavefunction. This work not only demonstrates a supersolid phase in a photonic platform but also paves the way for exploring quantum phases of matter in non-equilibrium systems, with potential applications in neuromorphic computing and advanced photonics.

Experimenting with and Abandoning a Terminal UI Library

While developing the game Kartoffels, the author attempted to create a high-performance terminal UI library, Kruci, to replace the existing Ratatui library. Kruci uses a declarative UI design and attempts to improve performance by avoiding pixel-by-pixel diffing calculations. However, Kruci encountered many challenges in handling events, state management, and Z-stacking. Ultimately, the author decided to abandon the project, concluding that optimizing Ratatui or focusing on game development would be more efficient.

Benchmark: Bitwise vs. Modulo for Even Number Check

Benchmark: Bitwise vs. Modulo for Even Number Check

This post benchmarks two methods for checking if a number is even in Pascal and C: modulo operation and bitwise operation. The bitwise approach (using the bitwise AND operator) proves significantly faster. A Pascal test iterating from 0 to MaxInt showed bitwise operations were nearly 15 times quicker than modulo. In C, while compiler optimization might translate modulo 2 to bitwise AND, the bitwise method still slightly outperformed modulo. This highlights the efficiency advantage of bitwise operations for even number checks in performance-critical scenarios.

GLP-1 Drugs: The Unexpected Economic Revolution

A new weight-loss medication, GLP-1, is silently reshaping the global economy. It not only helps people lose weight but also regulates impulse control. This is causing a massive disruption to industries reliant on impulsive spending, such as restaurants, entertainment, and advertising, forcing them to adapt. Some companies are already changing, converting malls into medical centers and shifting advertising strategies to long-term partnerships. However, this transformation also risks widening societal inequality due to varying access to the drug. This is a profound economic and social shift with far-reaching consequences.

Package Managers: Pandora's Box of Programming?

2025-09-08

This article critically examines the downsides of package managers in programming languages. The author argues that package managers automate "dependency hell," masking project complexity, and leading to excessive trust in third-party code. Especially in languages lacking robust standard libraries, inconsistent package definitions by different managers can even lead to "package manager managers." The author advocates for manual dependency management, believing it forces developers to think critically about dependencies and improves code stability and maintainability. While acknowledging the time cost, the author argues the security and control outweigh the convenience of automation, using Go's comprehensive standard library as an example.
