Judoscale focuses on providing rapid and reliable queue-time-based autoscaling, believing that queue time is the most critical metric for real applications. Their goal is to enable instances to scale up quickly, often within 10 seconds of a queue time increase. However, they've acknowledged that queue time may not always be the optimal metric for every situation and have developed an alternative method that can be more effective in certain cases. Queue time measures how long requests wait before being processed by servers, which directly correlates

AI agents are evolving to perform actions beyond basic Retrieval-Augmented Generation (RAG), facilitated by standards like the Model Context Protocol (MCP). This development necessitates fine-grained permissions and access controls, transitioning away from hardcoded user roles to a more dynamic authorization model, such as Policy-Based Access Control or Attribute-Based Access Control. The guide emphasizes the creation of a secure MCP server managed by Cerbos, a policy-driven authorization service, to ensure that AI agent tool access is governed by human-readable

The content discusses the responses to a previous post titled "Mr. Golang's Wild Ride," which has been widely shared across platforms like Reddit and HackerNews. The author reflects on the polarized reactions it generates, focusing on the dismissive criticisms and the more thoughtful comments. They highlight a tendency for experienced developers to overlook issues due to familiarity, while junior developers, with fresh perspectives, question the status quo. This drives the author to advocate for hiring junior developers for their ability to identify problems that seasoned developers

The article emphasizes the importance of HTTP caching for Rails developers, highlighting its potential to significantly reduce API requests—up to 90%—without requiring additional caching code. While many developers focus on fragment caching and related techniques, HTTP caching remains underutilized despite being built into HTTP clients and requiring no extra infrastructure. The writer points out that typical Rails APIs often serve fresh responses for every request, leading to unnecessary database queries and server load, especially with high traffic. This inefficiency arises mainly because Rails applications

The article by Lance Martin discusses the importance of context engineering in the functioning of AI agents, particularly in the realm of large language models (LLMs). Context engineering is described as a critical process that fills the context window of an agent with appropriate information throughout its task progression. Martin draws an analogy to computer systems, where the LLM acts as the central processing unit (CPU) while its limited context window functions like RAM, highlighting the need for careful information curation. As the capabilities of LLMs

The content discusses the use of the `then` method in Ruby for currying, noting its functionality but also highlighting that it can make code less readable. The author suggests experimenting with code to enhance learning, emphasizing that practical implementation helps retention better than mere reading. They mention looking into 37 Signals’ Writebook and suggest exploring alternatives like the `tap` method. Additionally, they compare the `then` method to `yield_self` and indicate that personal style preferences impact how one utilizes these methods.

Forward Email has focused on building reliable email infrastructure from scratch since 2017, unlike many email startups that rely on existing solutions like Amazon SES or Postfix. The analysis notes that most email startups fail, often because they do not understand the email infrastructure and attempt to solve non-existent problems. A significant failure rate among email-related companies is highlighted, with a report from Techstars showing only 5 successful exits out of 28 startups. The companies that succeed, like SendGrid and Mailgun, enhance

Claude Code allows users to customize and extend its functionality by registering shell commands known as hooks, which execute at various points in its lifecycle. This feature enables deterministic control over actions, ensuring they are performed consistently rather than relying on the system's decisions. Users are responsible for the safety of their hooks, as any misuse could lead to data loss or system damage, and Anthropic disclaims liability. A quickstart guide is provided to set up a hook that logs shell commands run by Claude Code. Prere

The author, active on X at @ordepdev, argues that the real bottlenecks in software engineering are not writing code but rather the processes surrounding it, such as code reviews, mentoring, testing, debugging, and communication. Despite the rise of large language models (LLMs) that enable faster code generation, this has not alleviated the complexities of understanding and maintaining that code. While LLMs can speed up implementation, they increase the volume of code, leading to more pressure on

Context Engineering is an emerging concept in AI that shifts the focus from "prompt engineering" to a broader understanding of the information provided to AI models. Tobi Lutke describes it as the art of supplying the necessary context for a task to be solvable by a large language model (LLM). As the development of AI Agents progresses, the importance of high-quality context becomes crucial; failures in these systems often arise from inadequate context rather than from issues with the model itself. Context goes beyond a single
