Why worker pools beat clustering for CPU-Heavy tasks on Node.js

Imagine you have a Nodejs server with endpoint that performs heavy CPU operations. By default your server runs on a single thread. This means it will freeze depending on the CPU load. If your server has other asynchronous endpoints, for example, to execute database operations, those endpoints would become unresponsive while the heavy load endpoint is processing. Our first idea is to create more ...

Unprivileged LXC + Docker: The runc Sysctl Permission Trap

sysctl: setting key "net.ipv4.ip_local_port_range": Permission denied I saw this error while trying to tune the network stack for a high-concurrency service running in Docker, which itself was hosted inside an unprivileged LXC container on Proxmox. The weird part? I was root inside the container. I expected that since I had already enabled nesting=1 and keyctl=1 in the LXC configuration, Docker ...

Link Building for Developers: Why Great Products Still Need Distribution

Most developers like to believe that a good product will eventually speak for itself. Sometimes it does. More often, it quietly sits on the internet, perfectly engineered, carefully documented, and almost completely invisible. That is not because the product is bad. It is because the web is crowded. Search engines, communities, newsletters, blogs, GitHub repositories, comparison pages, and docu...

Claude Moves Fast. Codex Ships.

I gave two big coding tasks to both Claude and Codex. Claude finished in about one hour. Codex took about eight. That sounds like a clean win for Claude until you look at what came back. The Claude output was fast, confident, and useless. Bad assumptions, broken code, missing integration points, half-followed rules, and a shape that would make the codebase harder to maintain even if I patched it...

UUIDs Explained Simply (and Why Every Developer Needs Them)

When building modern applications, one problem shows up everywhere: How do I uniquely identify data across systems? That’s where UUIDs (Universally Unique Identifiers) come in. What is a UUID? A UUID is a 128-bit unique identifier used to identify information in distributed systems. Example: 550e8400-e29b-41d4-a716-446655440000 It looks random - and that’s the point. Wh...

The smarter the model, the more it saves.

There is a belief, reasonable on its face, that has been quietly circulating among Claude Code power users since WOZCODE launched: that the plugin's advantage would fade as the underlying models got smarter. The argument goes something like this — if Claude can think more clearly, plan more efficiently, and make fewer mistakes on its own, why would it need a layer of optimized tooling on top? Inte...

LLM386: borrowing a 1990s idea for managing LLM context

In 1989, DOS had a 640 KB ceiling on conventional memory. EMM386 used the 80386 CPU's address-translation hardware to page chunks of a much larger memory space through a small fixed window inside that 640 KB. Programs that asked nicely got effectively unlimited memory through a peephole, by paging only what was relevant for the current operation. LLMs have the same problem. The context window is...

AWS Agent Registry: a private catalog to stop agent sprawl

Two months ago I discovered two of them were doing the same thing. The worst part: none of them have the same guardrails." This isn't the first time. The conversation repeats with predictable variations across platform lea...
