How OpenClaw's Memory System Actually Works

LLMs have no memory. OpenClaw builds the illusion of memory from files, conversation history, and retrieval — three subsystems working together. Here's how each one works, and where each one breaks.

Investing in Infrastructure: Meta’s Renewed Commitment to jemalloc

Meta recognizes the long-term benefits of jemalloc, a high-performance memory allocator, in its software infrastructure. We are renewing focus on jemalloc, aiming to reduce maintenance needs and mo…

The Scheduler | Internals for Interns

In the previous article we explored how Go’s memory allocator manages heap memory — grabbing large arenas from the OS, dividing them into spans and size classes, and using a three-level hierarchy (mcache, mcentral, mheap) to make most allocations lock-free. A key detail was that each P (processor) gets its own memory cache. But we never really explained what a P is, or how the runtime decides which goroutine runs on which thread. That’s the scheduler’s job, and that’s what we’re exploring today.

Why is my first C++ (m)allocation always 72 KB?

Why is my first C++ (m)allocation always 72 KB?? It’s the ’emergency pool’ for exceptions, here’s how I uncovered it using GDB and digging through the source code of libstdc++, glibc and Valgrind!
