Elizabeth from SigNoz introduces a newsletter focused on observability, OpenTelemetry, and open-source engineering. As an OpenTelemetry advocate, she aims to share insights about the auto-instrumentation process, which collects telemetry data (traces, metrics, logs) from applications without requiring code changes. She explains the distinction between the OpenTelemetry API, used for creating telemetry data, and the SDK, which implements the API, managing telemetry processing and exporting. Auto-instrumentation relies on instrumentation hooks to invoke

In early 2025, Andrej Karpathy introduced the term "Vibe Coding," which describes the practice of developing applications primarily through natural language prompts using Large Language Models (LLMs) and AI agents. This method allows non-technical founders to build minimum viable products (MVPs) quickly but has given rise to a new challenge: Vibe Coding Debt. This form of debt encompasses significant security issues that arise from LLM-generated code, which tends to prioritize code that runs over secure code

Modern TVs are not well-suited for children, as they involve complicated remotes and apps that distract from intended viewing. This often results in children feeling powerless and reliant on adults to choose content, which can lead to passive screen time. To address this issue, the author aimed to create a user-friendly device for their 3-year-old son that promotes independence and choice. The device should be tangible and give the impression that media is physically stored, as opposed to being stored "in the cloud," and

The company is developing a software platform for managing solar mini-grids, which includes an admin panel and mobile-friendly web apps for users to monitor and control the grids. The architecture features a standard IoT structure with a storage layer (Postgres, Timescale, and S3), a view layer (Vue web apps), and a business logic layer (NestJS services for timeseries data and transactions). Despite its conventional design, establishing a production-grade system took nearly a year due to the complexity of implementing

The content discusses Yaml, a human-readable data serialization language popular for configuration files. It references the use of PyYaml, Python's leading Yaml library, to parse Yaml files, highlighting a common issue known as the "Norway problem." This problem arises when the two-letter ISO country code for Norway ("NO") is misinterpreted as a boolean value (false) when parsed, due to its similarity to the English word "no." A suggested workaround is to escape the string by enclosing

The author discusses their experience with the satisfy matcher in RSpec, which they found useful for ensuring an attribute contains a specific string while excluding another. Despite trying several code variations, they couldn't achieve the desired outcome until they discovered the satisfy matcher, which allows tests to pass if a provided block returns true.

The author expresses a long-standing affection for the Xfce desktop environment, which they have appreciated since experiencing it on the Cobind Desktop. They reference a post by David Gerard from 2012 discussing the balance required for minimal desktop environments, praising Xfce for its longevity and balance between simplicity and functionality. The author shares a nostalgic screenshot of their desktop from 2008 while noting that Xfce remains user-friendly, lightweight, and efficient in 2026. They mention using KDE on their

Meteorologists have reported a significant decrease in winter snowfall across the Himalayas, leading to bare and rocky landscapes during a season that typically sees heavy snow. Recent winters have shown a decline in snowfall compared to average levels from 1980 to 2020, with rising temperatures causing rapid melting of whatever snow does fall. Additionally, some lower-elevation areas are experiencing increased rain instead of snow, partially attributed to global warming as noted by the Intergovernmental Panel on Climate Change. This phenomenon has led to

The author is exploring the implications of artificial intelligence, particularly large language models (LLMs), increasingly taking over the task of writing code. They note that a significant constraint for LLMs is their limited context length, which poses challenges for software development agents, especially given current memory shortages. The author suggests that "token efficiency" in programming languages could become a critical factor in language selection in the future, as more efficient languages could accommodate longer coding sessions while requiring fewer resources. They reference the RosettaCode

The author reflects on their early experiences with software development, where it was commonly taught to keep databases at a distance from the system's core design. The prevailing mindset was that the database should be considered merely an implementation detail, with emphasis on object-oriented programming that prioritized modeling in memory. Terms such as "domain model" and Domain-Driven Design promoted the idea that persistence should not influence system design, which led to a focus on in-memory objects rather than database structures. The rise of Object-Relational

The author reflects on previous design issues in LLVM IR, noting that some have been effectively addressed while highlighting several others that still need attention. This is not a complaint about LLVM, but rather an invitation to identify opportunities for improvement. The author, as the lead maintainer of the LLVM project, acknowledges that while the project has thousands of contributors, it struggles with insufficient code review capacity. There are more people writing code than reviewing it, which can lead to inexperienced reviews and potential issues in the codebase.

The OpenCode software (npm: opencode-ai), an open-source AI coding assistant, has a vulnerability identified as CVE-2026-22812. Prior to version 1.1.10, OpenCode automatically started an HTTP server on startup, now disabled by default in the newer version but can be enabled via command-line or configuration. When active, this server lacks authentication, allowing any connecting client to execute code with the user's privileges. Users are not notified of the server's operation.

The author discusses Justine Tunney’s cosmopolitan libc project, a toolkit that compiles C code into a binary runnable on multiple operating systems. Inspired by this, the author decided to create a simple Snake game that runs on Windows, Linux, and in browsers, all from a single source file and within a 16 KiB limit. The game follows standard Snake rules where the player controls a snake that eats food to grow longer while avoiding walls. Controls include arrow or WASD keys, with

In January 2026, Jordan Fulghum discusses how the advent of CLI agents like Claude Code has transformed his approach to self-hosting a home server. Fulghum had previously struggled with the complexities of self-hosting but found it enjoyable and streamlined thanks to Claude Code, which simplifies configuration tasks. He explains that this technology is now accessible for everyday users who may be hesitant to manage server uptime and technical details. Fulghum shares his experience of moving from a resource-intensive Plex server on a

The recent criticisms of the large corner radius of windows in macOS Tahoe point to both aesthetic and usability issues. Many users find the design comical and toy-like. More significantly, this design change has affected window resizing capabilities. Users are struggling to resize windows because the area where clicks are recognized is limited to a small 19 × 19 pixel zone near the corner. Due to the oversized corners, a majority of this area is now outside the window, causing confusion and frustration. Users instinctively try

Rye is a flexible, homoiconic programming language influenced by Rebol, Factor, Shell, and Go. It emphasizes a strict state management while allowing for a flexible syntax. Key features include the absence of Null, constants by default, treating everything as an expression, lack of keywords, and that all active elements are functions. Words are evaluated in a hierarchy of contexts. The document's initial section aims to provide an overview through practical code examples with minimal commentary, with more complex topics to follow in
