🥈 React Performance Tips: 12 Ways to Make Your App Faster

Keyv and Cacheable npm Supply Chain Compromise

An active npm supply chain compromise affected widely used packages in the keyv and cacheable ecosystems, along with packages owned by other maintainers. At least ten packages were published with a malicious preinstall hook named setup.mjs. The hook downloads a standalone Bun runtime, runs an obfuscated second-stage payload, collects cloud and CI credentials, and can publish trojanized versions o...

Breaking the Browser Sandbox: How to Build Native Desktop Automation Agents with Node.js and C++

For years, autonomous software agents have lived in a gilded cage. Constrained within the sanitized, highly structured confines of the Document Object Model (DOM) and isolated HTTP requests, web-based agents have parsed HTML strings, evaluated JSON payloads, and interacted with simulated browser environments using high-level protocol wrappers like the Chrome DevTools Protocol (CDP). They are brill...

Amazon Just Crossed $3 Trillion — and AWS Still Can't Build Fast Enough

Amazon just became one of only a handful of companies ever to cross a $3 trillion valuation. But the number that stopped me wasn't the market cap. It was AWS growing 37% year over year to $42.2 billion in a single quarter — its fastest pace in more than four years — and it still isn't enough. Andy Jassy's own words: even after lifting 2026 capital spending to roughly $220 billion, AWS "will sti...

`resource({ load: 'whenTracked' })`: what should wake a lazy resource?

A few days ago, I proposed resource({ lazy: true }) for Angular: resources load eagerly by design, and I wanted one that waits until something actually looks at it. This is the follow-up, because the design changed: for the better, and for reasons worth writing down. The whole thing turns on a question that looks trivial and is not: a lazy resource waits. Waits for what, exactly? Hypothe...

Love at first sight

I started playing with AI a couple of years ago with Cursor and Code Rabbit as the first tools a programmer had to learn. I hated them, to the core. They were intrusive, wanted to change every single line of code I wrote for the sake of optimization, syntax clarity, type safety, and there was no single one that went without scrutiny. That was the whole purpose of the beast, to annoy me. I was par...

Thumbnail Architecture for Small SaaS: Object Storage, Image CDN, or Resize on Upload?

Bottom line: for a beginner SaaS, put originals in object storage and have a backend worker write each thumbnail as a separate object with a deterministic key; don't make edge transformation or synchronous resize-on-upload part of the first critical path. This is the boring design, which is exactly what I want when my platform team owns the pager. It separates durable bytes from compute, lets the...

Enterprise MCP Gateway with Built-In Security: OAuth 2.0, RBAC, and Tool Access Control

TL;DR MCP servers are powerful, but they can expose production systems if anyone on the team can connect and run tools without guardrails. Imagine a new hire testing the app on their laptop and accidentally granting an MCP server access to the production database. Without governance, that is a realistic path to data leakage. Bifrost addresses this with three layers: Human-in-the-lo...

Left Brain vs Right Brain in Trading: What Science Says

Why your trading losses might not be strategy failures — they could be brain mismatches I failed at trading for 18 months. Not because my strategies were bad. Because I was using a right-brain strategy with a left-brain execution style. Then I discovered neuroscience research on hemispheric dominance. Applied it to trading. Cut losses by 60% in 3 months. This is the science, the self-...
