Why Go is the Perfect Language for Building AI Agents

2025-06-09

This article explores the advantages of Go for building AI agents. The author argues that the rise of AI agents necessitates high concurrency, long-running processes, and efficient resource management. Go excels in these areas due to its lightweight goroutines, efficient concurrency model, robust standard library, and convenient cancellation mechanisms. The article compares Go to other languages like Python and Node.js, highlighting Go's superior handling of concurrency, memory management, and error handling. A code example illustrates Go's elegant approach to inter-agent communication and state management. While acknowledging Go's relative lack of machine learning libraries, the article strongly advocates for Go as the ideal choice for building high-performance, scalable AI agents.

EU OS: A Common Linux Distro for the Public Sector (But Not an EU Project)

2025-06-09

EU OS isn't an official European Union project, but it should be. It's a proof-of-concept Fedora-based Linux distribution using KDE Plasma and bootable containers, designed for public sector organizations. Its value lies in providing a common base OS with options for layered modifications (national, regional, organizational). This ensures a consistent desktop environment, user management, and data handling. EU OS also partners with HackDays and endof10.org, promoting Linux adoption.

Software is About Promises: A Case Study in Personal Library Science

2025-06-09

This article explores the crucial role of 'promises' in software development. The author argues that a developer's promises to users, much like a product specification, should be clear and testable. Using 'Your Commonbase', a personal library software, as a case study, the article demonstrates how to break down software functionality (store, search, synthesize, share) into specific, achievable promises and prioritize development based on resources. The author highlights how clear promises protect developers, users, and the software's integrity.

OpenBSD Disk I/O Performance: More Threads Aren't Always Better

2025-06-08

This post benchmarks the random read/write and latency performance of a 1TB Crucial P3 Plus SSD on OpenBSD 7.7 using fio(1). Results show good I/O scalability in OpenBSD, but increasing job counts beyond an optimal point (6-8 concurrent jobs) degrades performance due to contention and CPU overhead. Compared to Linux, OpenBSD shows more sensitivity to concurrency in NVMe writes. The test also reveals that excessive threads significantly impact desktop responsiveness. Future tests will extend to USB storage.

Android's Ethernet Adapter Mystery: A Stupid Regex

2025-06-08

This post details the author's frustrating attempt to use a USB Ethernet adapter on their Android phone. The investigation revealed the problem wasn't driver support, but rather Android's `EthernetTracker` service using a regex `eth\d` to match Ethernet interface names. CDC Ethernet adapters create interfaces named `usbX`, resulting in non-recognition. The author meticulously documents the debugging process, including obtaining kernel configuration and analyzing Android source code. The root cause? A simple, restrictive regex. The post showcases impressive problem-solving skills but also highlights a potential flaw in Android's design.

futa: A Functionally Useless Terminal Assistant

2025-06-08

futa, powered by qwen3, is a terminal assistant that executes simple commands in an incredibly resource-intensive way. Users input any text, and futa uses a large language model to interpret it and then runs what it deems appropriate, potentially including (but not limited to) starting Docker containers or running git commands. futa is characterized by overconfidence, verbose explanations, and extremely low productivity; it might even corrupt your filesystem. The developers explicitly state futa is functionally useless and are not responsible for any resulting damage. In short, futa is a tool for entertainment and experiencing the quirks of AI, unsuitable for production environments.

Replacing Restic's REST Server with Nginx for Backups

2025-06-08

The author cleverly uses Nginx to replace Restic's REST server backup solution, creating two Nginx virtual hosts: append-only and admin. The append-only host prevents data deletion, while the admin host allows management operations. The configuration uses Nginx's DAV and LUA modules, employing several tricks to handle HTTP methods and response codes, and using regexes to modify the autoindex's JSON output. While the approach is somewhat hacky, it's effective and efficient. The author also discusses security concerns and mentions plans to simplify the configuration in the future.

Agentic Coding: Hype or Reality?

2025-06-08

This post reflects on the author's experience with LLMs and critically assesses the hype surrounding 'agentic coding'. While LLMs can generate usable code, building complete software projects, like an HTTP/2 server, requires intense micromanagement and algorithmic supervision. LLMs frequently get stuck, demanding human intervention and context adjustments. The author argues that current 'agentic coding' tools are largely overhyped, their success relying on the effort of experienced engineers rather than autonomous LLM capabilities. Only by addressing the problem of LLM context management can their true potential be unleashed.

Claude Code: Security First, But at What Cost?

2025-06-08

This post delves into the inner workings of Anthropic's Claude Code, a coding assistant. By intercepting communications between Claude Code and the Anthropic API using mitmproxy, the author reveals that it's slower and more expensive than alternatives like Cursor. This is due to its stringent security policies and multi-layered tool invocations. Claude Code meticulously assesses the security of every bash command and uses multiple tools (View, GlobTool, Bash, etc.) to process user requests, resulting in extra LLM calls and increased cost. While this approach prioritizes security, it compromises efficiency. Although Claude Code boasts a superior UX compared to other tools, its cost and speed require further optimization.

The Android Maintenance Nightmare: Why the Google Play Store App Count Plummeted

2025-06-08

A hobby Android developer with five years of experience maintaining MusicSync, a Google Play Music + Podcast replacement, shares the struggles of Android app maintenance and explains the 47% decline in Google Play Store apps. The article highlights the significant challenges compared to backend development, including Java/Kotlin compatibility issues, breaking changes from Google's frequent library updates (e.g., ExoPlayer, Google Auth), dropping support for older Android versions, forced upgrades across various components (Android Studio, Gradle, SDKs), unpredictable UI design guideline changes, and the deprecation or lack of maintenance for crucial third-party libraries like Picasso, Glide, OkHttp, and EventBus. The dual versioning scheme for Android versions and API levels adds further confusion. The conclusion emphasizes the higher maintenance cost of Android apps compared to server-side development.

LLMs: Helpful Coding Assistants or Creativity Killers?

2025-06-08

This article expresses concern over the over-reliance on LLMs. While acknowledging their potential to assist in coding and improve efficiency, the author argues that excessive dependence on LLMs weakens programmers' independent thinking and problem-solving skills, particularly for beginners, hindering their grasp of fundamental programming knowledge and the development of programming thinking. The author also points out that the quality of code generated by LLMs is inconsistent, prone to errors, and lacks creativity and artistry, potentially leading to a decline in code quality and even academic dishonesty. The author calls for regulation and limitations on the use of LLMs, especially in education, to avoid their negative impact on students' learning and creativity.

Seismic Shift in Algorithm Simulation: Memory Breakthrough

2025-06-07

A groundbreaking result has shaken the foundations of algorithm simulation. Ryan Williams's new research demonstrates that all algorithms can be simulated using significantly less memory than their original runtime, a vast improvement over previous best-known results. This breakthrough leverages a space-efficient tree evaluation algorithm by Cook and Mertz, cleverly segmenting Turing machine computations and using finite field encoding to achieve a near-quadratic improvement in space complexity. While not preserving the time bound, this landmark result has profound implications for complexity theory and opens avenues for future research, such as further reducing space complexity bounds, potentially leading to the separation of P and PSPACE complexity classes.
