AI Scrapers Meet Their Match: The Rise of 'Tarpits'

Frustrated by AI crawlers ignoring robots.txt, developer Aaron created 'Nepenthes,' malware that traps crawlers in an endless maze of static files. This 'tarpit' technique, inspired by anti-spam tactics, has sparked a wave of similar tools, including Gergely Nagy's 'Iocaine.' While criticized for potentially burdening servers and hindering AI progress, supporters see it as a rebellion against AI's overreach and a way for content creators to reclaim control. The debate highlights the tension between AI development and the protection of online content.

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.

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.

Cambridge Blockchain Network Sustainability Index: Bitcoin Mining Map Reveals Energy Consumption Patterns

2024-12-12

The Cambridge Centre for Alternative Finance (CCAF) released a mining map visualizing global Bitcoin mining energy consumption as part of the Cambridge Blockchain Network Sustainability Index. The map shows the share of Bitcoin mining hashrate by country and region, revealing a seasonal migration pattern of Chinese miners between ‘dry’ and ‘wet’ seasons to leverage cheaper hydropower. However, this migration pattern likely ended after the Chinese government crackdown on the mining industry in June 2021. The research is based on geolocation mining facility data collected in partnership with several Bitcoin mining pools and acknowledges contributions from BTC.com, Poolin, ViaBTC, and Foundry.

Newberry Library Unearths Largest Known Example of Rare Maguey Paper Manuscript

The Newberry Library in Chicago has made a remarkable discovery: a colonial-era Mexican manuscript, Ayer 1485, written on an exceptionally rare type of paper made from agave plants—maguey paper. The manuscript, a collection of sermons by Bernardino de Sahagún, a Franciscan missionary, contains nearly 50 sheets, far surpassing the number of known existing maguey paper sheets worldwide. The choice of maguey paper, a material with significant pre-Hispanic religious connotations, suggests a deliberate decision by Sahagún's indigenous collaborators, offering valuable insight into the complex cultural exchange during the early period of contact between Europe and the Americas. This find not only highlights ancient papermaking techniques but also enriches our understanding of this crucial historical moment.

Comptime Configuration in Zig: Clever Design in httpz and ztl Libraries

2025-01-13

This article explores the techniques of using compile-time metaprogramming for configuration in the Zig programming language. The author uses their httpz and ztl libraries as examples, demonstrating how a generic type parameter `T` can simultaneously serve as both application context and configuration. Functions defined within the `T` type can override the library's default behavior, while fields in `T` can configure scalar values. Compile-time checks ensure the correctness of the configuration and allow for compile-time optimizations, such as adjusting the virtual machine stack size based on the configuration. While this approach requires users to provide configuration at compile time, it offers significant performance improvements and is an effective strategy for building flexible and efficient libraries.

Engineer Implements Reversible 1D Cellular Automata Using Bitwise Operations

Richard Palethorpe, an engineer, created a demo using the GFXPrim library showcasing a one-dimensional binary cellular automaton and its reversible counterpart. The automaton evolves based on rules where each cell's state is determined by its own state and those of its left and right neighbors. The article details bitwise operation optimizations, such as parallel processing of multiple cells using 64-bit integers and bit rotation to simulate neighbor interaction. Reversible implementation is achieved by XORing with the previous state. The author explores compiler optimization and vectorization impacts on performance and ultimately implements an efficient rendering method.

Bloom Filters: The Secret to Making SQLite 10x Faster

2024-12-22

Researchers cleverly used Bloom filters to make SQLite analytical queries 10x faster. They discovered that SQLite's nested loop joins were inefficient, with much time spent on B-tree probes. By using a Bloom filter before the join operation to quickly filter out rows unlikely to match, and then performing B-tree probes only on potential matches, the number of probes was significantly reduced. Bloom filters have minimal memory overhead and were easy to integrate into SQLite's existing query engine, resulting in a significant performance boost. This improvement has been integrated into SQLite v3.38.0.

This paper delves into the complexities of time handling in Common Lisp and presents the author's solution: the LOCAL-TIME library. It traces the evolution of human time representation, from imprecise, context-dependent notations to precise scientific ones, highlighting the chaos introduced by political factors like daylight saving time. LOCAL-TIME uses an efficient fixnum-based representation, integrates world timezone data, and handles various time calculations and format conversions, thereby avoiding errors stemming from imprecise time representation—like the infamous Y2K problem.

IPv6 Isn't Hard, It's Just Different: A GitHub Case Study

A Mastodon post lamented the difficulty of IPv6 configuration. The author uses GitHub as an example to show that the problem isn't IPv6 itself, but inadequate configuration and monitoring. Many websites, while having IPv6 address records (AAAA), are actually inaccessible via IPv6 because the browser's Happy Eyeballs mechanism prioritizes faster IPv4. In one case, a customer's split VPN tunnel blocked IPv6 connections. In another, traceroute showed that IPv6 routing terminated earlier than IPv4, indicating a possible firewall rule or routing issue. The author concludes: take IPv6 seriously, or don't use it. Lack of IPv6 monitoring and automation makes problems difficult to detect and resolve.

Intensional Programming in Joy: Introspection with a Single Operator

2025-02-12

This article explores intensional programming in Joy, a stack-based functional programming language. Joy itself is extensional, lacking the ability to 'dissect' code blocks. The author proposes two intensional operators: 'map' and 'quota', proving their mutual expressibility. While behaviorally equivalent, intensional programs can distinguish a single operator from a subprogram with multiple commands. This opens avenues for exploring weaker notions of equivalence in intensional languages and demonstrates a robust approach to introducing intensionality in minimalist languages like Joy.
