Why Most Crypto Bots Get Sandwiched (And How to Prevent It) If you’ve ever tried deploying a crypto trading bot, chances are you’ve encountered the dreaded sandwich attack. It’s one of the most frustrating experiences for traders and developers alike. I’ve lost count of how many times my bots got caught in these attacks, but over time, I’ve learned how to mitigate them effectively. In this artic

I've been building AQE (Atomic Quantum Engine), a DOM selector engine that replaces tree traversal with flat bitmask operations. Instead of walking the DOM on every query, each node gets a 64-bit BigInt mask at sync time. Matching becomes a single integer AND. AQE Light is the free, open-source version — zero dependencies, MIT license, on npm now: npm install atomic-quantum-engine I'm looking for
I was out walking with my dog Dexter, daydreaming on the first properly warm day of the year. I was lost in my own mind mulling over a conversation I'd had with a fellow Game Developer about how we've adapted to the use of AI as software engineers. None of the existing labels fit. "Vibe coding", Karpathy's term, elicits a culture of care-free one-shotting with little to no regard for the code qual
If this is useful, a ❤️ helps others find it. All tests run on an 8-year-old MacBook Air. The AI feature is only as good as the UI around it. A powerful diagnosis that's hard to trigger, slow to show, or confusing to read doesn't get used. Here's what I learned from iterating on HiyokoLogcat's AI button. Inline with the content, not in a toolbar. My first version had an "AI Diagnose" button in the
Hello readers 👋, welcome to the 23rd blog in this JavaScript series! In the last post, we discovered how async/await makes asynchronous code feel as natural as synchronous code. Today, we are going to talk about a pair of operators that look identical but do completely opposite jobs: the spread and rest operators. Both use three dots (...), but one expands values out while the other collects valu
A* looks simple until you implement it. Then one question appears: Why does this algorithm find good paths without checking every possible path? The answer is its scoring structure. A* does not only ask, “How far have I moved?” It also asks, “How far do I probably still need to go?” A* is a shortest-path search algorithm. But it is not blind search. It combines: the real cost so far the estimated
