1. VSCode’s SSH agent is bananas
Total comment counts : 73
Summary
The article discusses the integration of Large Language Models (LLMs) into VSCode for remote editing over SSH, highlighting several key points:
LLM Integration with VSCode: There’s an interest in integrating LLMs into VSCode, especially since many users are employing these models to generate code, which often involves remote editing capabilities.
Issue of “Hallucination”: The term “hallucination” is used when LLMs produce incorrect code. An “agent” setup is suggested as a semi-effective solution where the LLM generates code, the agent runs it, errors are fed back to the LLM, and the process repeats.
Security and System Integrity: The iterative development process should not occur on the user’s laptop due to potential boundary issues with LLMs, suggesting the use of a clean, isolated Linux instance for such experiments.
Comparison with Emacs Tramp: The article contrasts VSCode’s remote editing capabilities with Emacs’s Tramp, which uses existing system resources without invasive installations. VSCode, however, installs additional software (like Node.js) via SSH, which raises security concerns due to its more aggressive setup.
Security Implications: The method VSCode uses to establish connections for remote editing is likened to certain security tool behaviors, hinting at potential risks, especially in sensitive or production environments.
Conclusion: Despite these concerns, the integration of custom connections in VSCode for development purposes like working with Fly Machines does not require addressing these security issues directly, but the knowledge is shared for educational purposes.
Overall, the article serves as both a technical discussion and a cautionary tale about the implications of integrating complex, potentially insecure systems into everyday development environments.

The article critiques the underlying design of Visual Studio Code (VSCode), particularly focusing on its SSH extension:
URI Formats: VSCode uses two formats for workspace URIs - a simple hostname format and a more complex hex-encoded JSON format when additional configuration details are required. Notably, if the hostname includes an uppercase letter, it’s necessary due to how VSCode handles case sensitivity when saving recent workspaces.
Case Sensitivity Issues: Workspaces saved in recent history are lowercased, which can lead to issues if the original URI contained uppercase letters.
Extension Configuration: The SSH extension allows for configuring extensions to be installed on the server side. However, there’s a limitation when connecting to Windows hosts. The system uses CMD to invoke PowerShell, passing extension configurations as command-line arguments. This method is limited by CMD’s 8191 character limit for arguments, potentially causing connectivity issues if too many or too large extensions are specified.
Overall, the author portrays VSCode’s architecture, especially its SSH handling, as somewhat makeshift or inelegant, relying on workarounds that might not be robust or scalable.

8. Generating Voronoi Diagrams Using Fortune’s Algorithm (With Odin)
Total comment counts : 13
Summary
The article discusses the implementation of Fortune’s Algorithm for generating Voronoi Diagrams, which partition a plane into regions based on proximity to given points or “sites.” Here are the key points:
Complexity and Recommendation: Implementing Fortune’s Algorithm can be challenging and time-consuming. For practical purposes, unless dealing with many large diagrams, simpler O(n^2) methods or pre-existing libraries are recommended due to their ease of use.
Voronoi Diagrams: These diagrams are useful for tasks like procedural map generation. Each cell in the diagram corresponds to a site, with boundaries where distances to neighboring sites are equal.
Fortune’s Algorithm Overview:
- It uses a sweep line approach, moving from left to right across the plane.
- As the sweep line encounters sites, it creates parabolic arcs or “bubbles” around them.
- Collisions between these arcs form the Voronoi cell edges, and where multiple arcs meet, Voronoi vertices are created.
Key Concepts:
- Sweep Line: Moves across the plane, triggering events.
- Beachline: Comprises arcs formed by sites, dynamically changing as events occur.
- Events: The algorithm processes site events (when a new site is encountered) and circle events (when three arcs form a circle, leading to a vertex).
Implementation Challenges: The article hints at the complexity involved in handling these events and the dynamic changes in the beachline, suggesting that the implementation requires careful management of these elements.
Visual and Conceptual Aids: Terms like “beachline” and “sweep-line” help visualize the algorithm’s operation, although the actual computation skips unnecessary steps by focusing on significant events rather than pixel-by-pixel processing.
Overall, while Fortune’s Algorithm offers an efficient O(n log n) solution for Voronoi diagram generation, its implementation complexity might deter those not focused on performance-critical applications.

Summary
The article discusses the challenges operations teams face with manual procedures that are tedious yet critical, often termed as “slogs.” These procedures, such as modifying infrastructure or provisioning user accounts, can grow complex and cumbersome over time, demanding attention without offering intellectual satisfaction. The author introduces the concept of “do-nothing scripting” as a solution to gradually automate these manual processes.
Key Points:
Manual Procedures and Toil: Operations teams often deal with manual, repetitive tasks that require focus but not much cognitive engagement, leading to toil.
The Problem with Automation: While individual steps in these procedures could be automated, doing so piecemeal doesn’t significantly reduce the workload or complexity, leading to a perception of futility.
Do-Nothing Scripting: This method involves creating scripts that outline each step of a manual process without actually performing the tasks. These scripts:
- Provide a structured way to execute tasks.
- Serve as a foundation for future automation by encapsulating each step into functions.
- Lower the threshold for starting the automation process, making it easier to transition from manual to automated tasks over time.
Benefits: Although do-nothing scripts don’t immediately automate the work, they:
- Make the process more visible and manageable.
- Encourage incremental automation by providing a clear path to modify individual steps.
- Reduce the likelihood of errors and procedural drift.
Broader Impact: The concept has been well-received in tech communities, as evidenced by multiple pingbacks from various tech and web development blogs, suggesting its practical value and interest in the approach.
In essence, the article advocates for a strategic approach to automation through do-nothing scripting, which not only simplifies current manual work but also paves the way for future automation, reducing toil and increasing efficiency in operations teams.
