Stop Using AI to Cut Corners: Your Boss Knows

2025-07-26

A seasoned professional expresses concern about employees' over-reliance on AI for writing. With extensive reading and writing experience and years of working with LLMs, he can easily detect AI-generated text. He argues that over-reliance on AI reduces efficiency and deprives employees of the learning and critical thinking involved in writing, ultimately resulting in lower quality work. He encourages employees to invest time in crafting their work, expressing their thoughts in their own words, and showcasing their personal value.

Single Rust Codebase Conquers Major GPU Platforms: A Milestone in Cross-Platform GPU Compute

2025-07-26

An exciting project has achieved the feat of running compute logic on all major GPU platforms (NVIDIA CUDA, AMD/Intel/NVIDIA Vulkan, Apple Metal, Windows DirectX 12, WebGPU for browsers, and a CPU fallback) from a single Rust codebase. Leveraging Rust's features like `#![no_std]`, conditional compilation, newtypes, enums, and traits, the project achieves impressive cross-platform generality. The `cargo` build system and testing framework streamline the development process. While challenges remain, such as compiler backend integration and debugging experience, this marks a significant step forward for Rust in cross-platform GPU computing.

Keep Pydantic Out of Your Domain Layer

2025-07-26

This article discusses how to avoid letting Pydantic models creep into your domain layer when building larger applications, maintaining clean, testable code. The author argues that while Pydantic is convenient, using it in the domain layer creates tight coupling. The article introduces using the Dacite library to convert Pydantic BaseModels to plain Python dataclasses and demonstrates, via an example, how to cleanly separate concerns between application, domain, and infrastructure layers, resulting in a more maintainable and testable architecture.

X-Forwarded-For Header: Trust Issues and Security Strategies

2025-07-26

The X-Forwarded-For (XFF) HTTP header is crucial for tracking the origin IP address of client requests, especially when traversing multiple intermediaries like proxies and load balancers. However, XFF is not foolproof; malicious actors can forge it. This article delves into XFF's mechanics, uses (user authentication, load balancing, data localization, etc.), security risks (spoofing, invalid IP addresses, injection attacks, etc.), and how to use XFF safely. It covers identifying the true client IP using trusted proxy lists or counts, and recommends the more secure Forwarded header as an alternative.

Recursers on AI: A Pragmatic Approach to LLMs in Programming

2025-07-26

Recursers, a 6-12 week programming retreat with an integrated recruiting agency, grapples with the impact of AI on programming. Instead of simply embracing or rejecting AI, they surveyed over 3000 alumni to understand the implications of LLMs on their work and learning. Findings revealed significant diversity in how programmers utilize and view AI tools, dependent on experience, project type, and team size. RC emphasizes three key takeaways: working at the edge of one's abilities, maintaining rigor, and learning generously. Ultimately, RC advocates for a pragmatic approach, focusing on the importance of active learning and critical engagement with AI, emphasizing its role as a tool to enhance, not replace, human agency.

Generic Containers in C: A Safe and Efficient vec Implementation

2025-07-26

This article details the implementation of a type- and bounds-safe generic container, `vec`, in C. `vec` is essentially a resizable array, dynamically growing using `realloc`. The author explains the implementation, including the `vec_push` function and error handling for memory allocation. Two improved interfaces, `vec_push_cap` and `vec_push_auto`, are explored for performance optimization. Bounds safety is discussed, along with interoperability with traditional C arrays via the `vec2array` macro.

Tattoy Now Supports Animated Cursors

2025-07-26

Tattoy terminal emulator now supports animated cursors! It uses the same format as Ghostty, rendering the cursor using custom shaders. While Tattoy renders using UTF8 text-based "pixels" ("▀" and "▄"), unlike Ghostty's pixel rendering, some subtleties might be lost, but the pixelated effect can be pleasing. Development challenges included supporting transparency for anti-aliased edges, ultimately solved by creating a pixelized version of the terminal and post-processing. Currently, there might be some lag on larger terminals, which will be addressed through future performance improvements and potentially by Tattoy taking over all cursor rendering from the host terminal emulator.

MIT's 6.001: From Scheme to Python – A Paradigm Shift

2025-07-26

MIT's introductory programming course, 6.001, shifted from Scheme to Python, reflecting a change in programming paradigms. In the 1980s, programming focused on clean, efficient code, akin to understanding electronic components thoroughly. Today, programmers grapple with massive, complex libraries, requiring extensive testing and debugging to understand their behavior. The revamped 6.001 is robot-centric, emphasizing system robustness, with Python's choice possibly due to readily available robotics interface libraries.

Eleventy Ditches Luxon, Builds Custom RFC 9557 Date Parser

2025-07-26

To reduce Eleventy's client-side bundle size and prepare for native Temporal API support, the team decided to replace the Luxon date parsing library with a custom RFC 9557-compliant solution. The new library is smaller, more accurate, and its output matches both the upcoming Temporal API and Luxon, although some breaking changes exist. This ultimately simplifies maintenance and improves performance.

Modern CSS: The End of SPAs?

2025-07-26

This article critiques the overuse of Single-Page Applications (SPAs). The author argues that modern browsers now offer native CSS transition capabilities (View Transitions API and Speculation Rules), enabling smooth page transitions without needing extensive JavaScript. SPAs often lead to performance issues, such as slow loading times, inconsistent scroll behavior, and SEO challenges. The author advocates returning to HTML and CSS, leveraging native browser features to build faster, more efficient, and SEO-friendly Multi-Page Applications (MPAs), avoiding the performance and maintainability sacrifices often made for the sake of an 'app-like' feel.

Tree's JSON Output: A Cautionary Tale of Assumptions

2025-07-25

The 2.0 release of the `tree` command introduced the ability to output un-indented JSON via file descriptor 3 (Linux only). However, this initial implementation made a dangerous assumption about the user's environment, leading to widespread compatibility issues. Version 2.0.2 rectified this by requiring the `STDDATA_FD` environment variable to be set. This highlights the importance of avoiding assumptions about the user's environment in software development. The improved `tree` command now offers flexible structured data output via `STDDATA_FD`, easily processed with tools like nushell.

Kiro: Amazon's Agentic IDE Revolutionizes Development

2025-07-25

As an AWS Community Builder, I got early access to Kiro, Amazon's new AI-powered development IDE. Kiro isn't just another code completion tool; it's an 'agentic' IDE capable of understanding and executing complex, multi-step projects. I built a portfolio website, contributed to open-source projects, and developed internal tools, demonstrating Kiro's significant productivity boost. Kiro's core is 'spec-driven development': invest upfront time defining requirements and architecture, then let Kiro autonomously execute much of the coding. While Kiro has limitations—it might need manual intervention with complex issues—it signals a fundamental shift in software development: from writing code to steering AI.

tsbro: TypeScript in the Browser, No Build Steps Needed

2025-07-25

tsbro is a new library that simplifies using TypeScript in the browser. It bypasses the browser's import system, using synchronous XHR to fetch TypeScript code, transpiling it to JavaScript with swc wasm, and converting it to CJS for synchronous require. This allows developers to run TypeScript code directly in the browser without build steps, and use external libraries like Preact, ideal for quick prototyping or PoCs. Current limitations include difficult-to-read stack traces and the need for manual ambient declaration files.
