I Tried Topcoat: Rust’s New Full-Stack Web Framework

Rust web development just got more interesting. If you prefer a video version: A few days ago, I spoke with Carl Lerche and Julien Scholz about Topcoat , a new batteries-included framework for building full-stack reactive web applications with Rust. Now I have finally tried it myself. Topcoat comes from the ecosystem behind Tokio and Axum, but it aims to provide a very different experience: routing, server-side rendering, reactive components, UI tooling, asset bundling, an...

Processing 100MB PDFs in the Browser: The Performance Optimizations That Made TinyPDF Usable

Processing 100MB PDFs in the Browser: The Performance Optimizations That Made TinyPDF Usable When I built TinyPDF ( https://tinypdf.cn/?utm_source=devto&utm_medium=blog&utm_campaign=performance_optimization&utm_content=devto_performance_2026-07-28 ), I had one hard rule: no backend. Everything had to run in the browser. No file uploads, no servers, no costs. Just drag, drop, compress, download. But when I tested the first version with a real portfolio—88MB, 45 pages, full o...

The Bug I Never Wrote: What Testing Failure Taught Me About Solana

100 Days of Solana, Day 100 Where I started I'd built REST APIs for years but had never touched a blockchain, or written a line of Rust. The curiosity how blockchain works, started my curiosity. What I expected I came in with a Web2 instinct: tests exist to prove your code does what it's supposed to do. Write the function, write a test that calls it, watch it pass, move on. A "failing test" was something you fixed, not something you shipped on purpose. ...

AB-100 Exam Experience: Architecture, Copilot Studio, Dynamics 365, and No Code

I recently passed the Microsoft AB-100 exam as part of the Microsoft Frontier Transformation Engineer journey. 🎉 After previously taking AI-103 , I found AB-100 to be a very different type of exam. While AI-103 is closer to the implementation and development side of building AI solutions, AB-100 is strongly focused on: Solution architecture Business requirements Technology selection Microsoft Copilot Studio Dynamics 365 Choosing the right Microsoft technology for each s...

Claude Opus 5 Lands on Amazon Bedrock — The Agentic Engineer #23

This is a cross-post from The Agentic Engineer newsletter — Issue #23. The Big One: Claude Opus 5 Lands on Amazon Bedrock The first 5th-generation Opus is here. Claude Opus 5 landed on Amazon Bedrock on July 24. Anthropic's claim: it matches Fable 5 intelligence across agentic coding, knowledge work, visual understanding, and long-horizon tasks. At Opus pricing. That last part matters. Fable 5 was positioned as enterprise-tier compute. Most teams weren't running it at...

权重即数据:神经网络权重空间学习如何成为 AI 的下一类训练集

https://www.youtube.com/watch?v=sVeEc3H6bA4 权重即数据:神经网络权重空间学习如何成为 AI 的下一类训练集 以下位 TWIML AI Podcast 第 772 期《Why Models Are AI's Next Training Dataset》访谈转录整理,嘉宾为圣加仑大学 AI 与机器学习教授 Damian Borth,主持人 Sam Charrington。 介绍详细内容之前,先说说WSL是否等同于模型蒸馏? 答案是不是一回事,但容易混着叫。先把两件事拆开,再对照 Borth 的"权重空间学习(WSL)"你就清楚了。 1. Anthropic 骂阿里那件事是什么 Anthropic 2026 年 6 月致信美国参议院,说阿里 Qwen 团队在 4/22–6/5 期间用近 2.5 万个假账号调 Claude 约 2880 万次 ,把 Claude 的回答当训练数据去训自己的模型,他们叫它" 蒸馏攻击(distillation attack) "。 这...

Decoupled User Management in Python

Hands-On tests with 'UserHarbor' and IBM Bob: A Modular Approach to Python User Authentication and Permissions Introduction When evaluating open-source libraries for core application infrastructure - such as authentication, session management, and fine-grained Role-Based Access Control (RBAC) - getting hands-on with a complete reference application is invaluable. This is especially true for libraries aiming to be framework-agnostic, promising flexibility but requiring more...

Why I'm Starting Before I'm Ready

Stop Waiting. Start Building. For a long time, I believed I needed to be "ready." Ready with a stronger portfolio. Ready with more skills. Ready with a clearer career plan. So I waited. Eventually I realized something uncomfortable: Confidence isn't built before you start. It's built because you start. I'm an AI & Data Science graduate figuring things out in public. Right now I'm: Learning AI beyond what college taught me. Building projects that solve real ...

Why Online Doctor Directories Keep Letting You Down

If you have ever tried to find a new physician through a search box, you already know the frustration: outdated phone numbers, doctors who left the practice two years ago, and "accepting new patients" labels that turn out to be fiction. Anyone who has read the candid breakdown in Online Doctor Directories: A User's Guide to a Very Imperfect Tool will recognize the pattern immediately, because the core problem is not laziness on anyone's part — it is a data engineering problem hiding inside a h...

Replicating GitLab's Centralized CI/CD Pipeline in GitHub Using a Central Repository to Avoid Duplication

Introduction Transitioning from GitLab’s centralized CI/CD pipeline structure to GitHub Actions presents a unique challenge for developers accustomed to GitLab’s modular approach. In GitLab, a central 'pipelines' repository acts as a single source of truth, referenced by individual projects via the include keyword. This mechanism eliminates duplication of CI/CD configurations, ensuring consistency and reducing maintenance overhead. However, GitHub Actions operates under a different p...

Pilum: From Launch to Production-Ready in 3 Months

Github URL: https://github.com/SID-Technologies/Pilum In December 2025, I open-sourced Pilum , a multi-cloud deployment CLI that deploys to Cloud Run, Lambda, Azure, Cloudflare Pages, npm, Homebrew, and Docker Hub from a single pilum.yaml . The announcement post covered the architecture: recipes, ingredients, handlers, wave-based execution. That was the "it compiles and the tests pass" version. Three months and 40+ pull requests later, Pilum deploys all of SID Technologies , platfo...

Aux Control — Let the whole room vote on the music

Built this for house parties/get-togethers where everyone has opinions about the music and no one wants to be DJ all night. How it plays: the host starts a session on their own device (phone, laptop, whatever's hooked up to the speaker) and it shows a join code and a QR code . Guests scan it with their phone camera — no app to install, it just opens in their mobile browser — type a name, and they're in. From there guests search a music catalog and queue up tracks they want played. Every...
