Background Gemini 3.5 Flash launched at Google I/O 2026 with a bold claim: it beats Gemini 3.1 Pro on coding and agentic benchmarks — while running 4x faster. At the same time, X (formerly Twitter) is full of posts saying it hallucinates constantly and doesn't…

The microsecond-level performance data that forced our complete architectural rewrite

This is Part 3 of the Core Rust Concepts series. Part 1 — Ownership, Borrowing, Lifetimes, Traits, Result/Option, Pattern Matching Part 2 — Closures, Iterators, Generics, Enums, Smart Pointers, Async/Await Table of Contents Macros Modules & the Cargo Ecosystem…

If you've ever tried to debug a DNSSEC misconfiguration using dig, you know the pain. You're staring at a wall of raw text, manually cross-referencing DS records against DNSKEY records, tracing through TLD delegations one query at a time. It works — but it's…

Most Rust developers don't think about CJK until they need it. Then they discover that embedding Japanese text in a PDF, building a search index over Chinese content, or normalizing Korean input involves a stack of interlocking problems that Latin-script…

I Just Wanted to Reuse Async Functions in Rust. I Ended Up Building a Tiny Task Manager I am currently studying Rust, and one of the things that kept bothering me was surprisingly simple: How do I reuse an async function more than once in a clean way? At…

Harnessing Power with Rust and Go: A backend developer's journey Hello, fellow developers! I’m Web Developer Travis McCracken, and today I want to share some insights into my work with backend development, especially with two of the most exciting programming…

My embedding pipeline used to take many hours. I'd kick it off, go do other work, come back, find a problem in the output, fix it, run it again. A single version of my semantic pipeline took three or four full runs before I was happy with it. That's a full…

The Problem We Were Actually Solving I still remember the day I was tasked with setting up an admin dashboard for our crypto digital store. The catch - we were operating in a country with strict financial regulations, which made it impossible to use conventional…

引言 在前端开发中，JavaScript一直是绝对的主角。但随着应用复杂度的提升，某些计算密集型任务用JS实现往往性能不足。WebAssembly的出现打破了这一限制，而Rust凭借其零成本抽象和内存安全特性，成为了编写Wasm模块的最佳选择。 性能对比 环境搭建 curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | shrustup target add wasm32-unknown-unknowncargo install wasm-pack…

The Problem We Were Actually Solving In 2023 we launched a SaaS tool for performance engineers. Nothing fancy—just a low-latency endpoint profiler that ingests traces and returns flamegraphs with flamegraph.js. We didnt need Stripes UI. We needed a way to…

I had a system prompt that ended with: Reply with only a JSON object. Do not include code fences. Do not include explanation. That should be enough. It is not. Over a week of structured-output calls (12,400 of them, mostly Claude Sonnet 4.5 and 4.7), I logged…

A few weeks back there was a 22-minute window where Anthropic returned a high rate of 5xx responses. Not a full outage. Degraded. Our agent service had a retry policy that backed off and tried again on 5xx. With six workers and a shared retry budget that…

The Problem We Were Actually Solving We needed a way to move money out of countries where PayPal, Stripe, and Gumroad had no footprint. Our micro-payment layer already integrated with local aggregators—EasyPaisa in Pakistan, bKash in Bangladesh, Flutterwave…

Most RAG tutorials start the same way: "First, install a vector database…" Then come the embedding models, the chunking strategies, the similarity thresholds. By the time you can ask a question about a PDF, you've deployed three services and written 200 lines…

React 19 Hydration Mismatch — Root Cause & Fix If you've upgraded to React 19 and started seeing hydration errors like: Error: Hydration failed because the initial UI does not match what was rendered on the server. Here's the actual root cause and how to…

Most AI agents wait. They sit idle until a human types something, respond, then go back to waiting. Garudust Agent can be different. With garudust-cron, you schedule tasks using standard cron syntax — the agent wakes up, runs a full LLM loop with all its…
