Is Cursor Really That Great? A Veteran Programmer's Honest Review

2025-05-10

The author provides an in-depth comparison of the popular code completion tool Cursor with other options. They find that Cursor's core technology is not fundamentally different from Copilot, both relying on Claude or GPT models. Cursor excels in actively searching and referencing other files within a project, but it can sometimes be overly 'smart,' even creating new files without permission. The author prefers the o1 model for its more precise and reliable debugging capabilities. The article concludes that those excessively praising Cursor might lack programming experience, confusing the power of AI with the tool itself. The author stresses that choosing an editor should be based on personal preference rather than blind following of trends.

Prolog Education Crisis: A Stack Overflow User's Plea for Reform

2025-05-10

A Stack Overflow user confesses to violating platform rules by providing excessive Prolog help, realizing it's counterproductive. The root problem? Many Prolog assignments stem from professors who don't understand the language themselves. Students' first encounter is often confusion, not understanding. The user proposes a two-part solution: a small, well-annotated solution database to answer even basic questions, and professor-ready slides for teaching Prolog even with limited expertise. This, combined with a moratorium on solving homework problems directly on Stack Overflow, aims to improve the Prolog learning experience.

MCP: A Protocol in Need of a Major Overhaul?

This article presents a critical analysis of the Model Context Protocol (MCP). The author attempted to build an MCP server, only to find the documentation lacking, design decisions bizarre, and the HTTP transport options (SSE+HTTP and the so-called "Streamable HTTP") overly complex and confusing, far inferior to the simplicity and efficiency of WebSockets. The author argues that MCP's excessive flexibility leads to increased complexity, higher maintenance costs, and security risks. They suggest replacing the existing HTTP transport with WebSockets and simplifying the protocol design for improved usability.

lsds: A One-Stop Shop for Linux Block Device Settings

2025-05-09

Managing disks and I/O on Linux often involves running multiple commands like lsblk, lsscsi, and nvme list, then manually correlating their output. To streamline this, a Python program called `lsds` was created. It directly reads information from the `/sys/class/blocks/...` directories, consolidating key disk details into a single, easy-to-read output. This includes device name, size, type, scheduler, rotational flag, model, queue depth, number of requests, and write cache settings. `lsds` is highly customizable, allowing users to specify which columns to display and providing a verbose mode for tracing information sources. This tool significantly simplifies the complexity of managing Linux disks.
