AutoLearn is an MCP server designed to transform an AI agent's reasoning steps into reliable and cost-effective deterministic code that performs consistently. It automatically captures the unique reasoning patterns of each AI agent, creating a personalized skill library without requiring manual skill creation or training. As agents encounter new scenarios, their skills improve, countering the typical 10% failure rate of AI tool calls, especially in multi-step workflows, where failures can escalate. By converting inconsistent AI reasoning into deterministic code, AutoLearn reduces costs associated

The future of AI coding in enterprises is shifting towards a focus on specification-driven development, shared context, and collaboration, rather than relying on "vibe coding." Despite viral claims of AI being able to generate a significant portion of code, this does not reflect the reality in larger engineering organizations, which manage complex codebases with rigorous quality and security standards. Industry veterans Kent Beck, Bryan Finster, Rahib Amin, and Punit Lad emphasize the need for a strategic approach to AI adoption rather than succ

This guide outlines the process of building a key-value database from scratch. A key-value database allows users to store and retrieve data using keys, similar to JavaScript objects. The main function of a database is to persistently store data and facilitate efficient retrieval. To store data, key-value pairs are added to a file (e.g., db.txt). To look up a key, one must iterate through the pairs to find a match. Updates involve replacing the existing value for a key, and deletes

Warbler is a tool in the JRuby ecosystem designed to package Ruby applications along with their dependencies into a single deployable file. This update explores how to use Warbler effectively. In the Java ecosystem, applications have long been distributed as JAR (Java ARchive) files, which are organized zip files that contain compiled Java bytecode, resources, and metadata. Deployable web applications use WAR (Web ARchive) files, while enterprise applications may use EAR (Enterprise ARchive

The content describes a security incident involving the potential compromise of AWS accounts, specifically related to a sudden surge of 600 instances created within three hours. AWS flagged this activity, raising a health event, and there were requests made to increase the SES (Simple Email Service) quota. The investigation points to older IAM accounts, which had not been active for years, suddenly logging in and changing passwords, raising suspicions about unauthorized access possibly through an API key or a lack of multi-factor authentication (MFA).

The LLM Brain Rot Hypothesis suggests that continuous exposure to low-quality web text, or "junk" text, can lead to cognitive decline in large language models (LLMs). A series of controlled experiments using Twitter/X data was conducted, categorizing data based on two criteria: engagement (M1) and semantic quality (M2). The results showed that LLMs pre-trained on junk datasets experienced significant declines in reasoning, contextual understanding, safety, and an increase in harmful traits such as psych

The URL Pattern API, now available in the URLPattern interface, simplifies URL matching by allowing developers to use a standardized syntax. This API helps avoid complex regular expressions or third-party routing libraries for handling URL changes. It streamlines tasks like URL parsing and data extraction through methods such as .exec() and .test(), resulting in cleaner and more readable code. Before the API's introduction, developers often had to combine the older URL interface with complex regular expressions, making URL pattern matching cumbersome. The new API

The content discusses a Turbo Pascal 3.0-compatible compiler called PASTA/80, designed to generate machine code for Z80 microprocessors used in classic and modern machines such as the ZX Spectrum and CP/M. It follows a single-pass recursive-descent parsing approach, resulting in fast compilation, though it may not produce the most efficient code compared to more advanced compilers like LLVM. The supported dialect closely resembles Turbo Pascal 3.0, with some enhancements from later versions. Limitations exist

The author reflects on a past job interview where they advocated for using a straightforward `switch` statement for implementing protocol handler dispatch, rather than complex structures like jump tables or binary searches. They believe in starting with the simplest solution and evaluating performance through compiler output. The interviewer preferred a more intricate approach, highlighting a disconnect in their expectations. This experience sparked the author’s curiosity about the performance differences between table-based and comparison-based dispatch methods. They attempted to conduct an experiment to explore these differences, fueled by insights
