Go 1.26 made Green Tea the default GC. We observe its cache-friendliness with perf, visualize the heap to see how Go allocates, and poke at a sparse-page problem a non-moving collector like Go’s struggles with.

The Rust performance book features over a dozen different profiling tools. So I’m not sure if the world needed a new Rust profiler. Still, I spent the last 6 months building hotpath-rs. In this post, I’ll describe the design decisions behind the library and share a few performance challenges I encountered while working on it. We’ll go deep into the low-level details like cache-line contention, async futures instrumentation, and decoding raw CPU traces back into Rust symbols.

Hotpath. Use to diagnose performance issues.

Open-Source Memory Engine for LLMs, AI Agents

What is Memori Memori enables any LLM to remember conversations, learn from interactions, and maintain context across sessions with a single line: memori.enable(). Memory is stored in standard SQL databases (SQLite, PostgreSQL, MySQL) that you fully own and control.

Why Memori?

One-line integration - Works with OpenAI, Anthropic, LiteLLM, LangChain, and any LLM framework SQL-native storage - Portable, queryable, and auditable memory in databases you control 80-90% cost savings - No expensive vector databases required Zero vendor lock-in - Export your memory as SQLite and move anywhere Intelligent memory - Automatic entity extraction, relationship mapping, and context prioritization

Beads - A memory upgrade for your coding agent. Contribute to steveyegge/beads development by creating an account on GitHub.

Frustrated by elusive names and misplaced phones? The science of memory reveals ways to improve your powers of recall. This Psyche guide provides practical, science-backed memory techniques and tips to help readers improve their ability to recall everyday information like people’s names and shopping lists.

I love that people are debunking the “Mandela Effect”

Web review of Ervin

Here’s another post on Scribe Rip that has a li’l more info.

I don’t wanna go overboard since I am old and I don’t like learning things. But I need to learn all the conditions and other rules in the new D&D version.

Speaking of those li’l keyring cardboard flashcards, I’m looking for info on how to best use them effectively. For example if I’m using spaced repetition it seems difficult to sort them if I’m studying on a bus or something. If I’m at a table, then sure—I can unclasp the ring and physically rearrange the cards according to the spaced repetition schedule, and I can shuffle the to get them in a different order (or is that bad? Should they stay in the same order?).

Maybe if I have a way to mark the cards I can study on-the-go and then sort them out when I’m in a calmer place.

One idea would be to use light pencil marks:
