LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

The only proper way to debug 16-bit code on Qemu+GDB

(or nearly so...)

GDB is undeniably an extremely versatile debugger, with the ability to add breakpoints, watchpoints, dump memory, registers, and the source code (along with its corresponding assembly). These features make it the perfect Swiss Army knife for most programmers. In addition to that, the possibility of implementing a 'GDB Stub' and automatically supporting GDB in your application makes it an almost universal debugger for a variety of tasks.

Qemu, like other virtual machines (such as 86Box), also implements debugging via GDB Stub, which enormously facilitates the development of bootloaders, operating systems, and more. The support for 32-bit and 64-bit code is quite good, and I have never seen any complaints about it. However, for 16-bit/real mode...

Is debugging in 16-bit/real mode really that bad?

If you have ever tried to debug 16-bit code on Qemu, you know how painful it can be:

Although Microsoft no longer supports Windows XP updates, I'm sure many users still use it due to personal habits or job demands. Therefore, XP's product keys may still be necessary. Here lies the most comprehensive list of Windows XP product keys.

The following CD keys are official and original from Microsoft, primarily used for Windows XP Professional Service Pack 2/3 VOL/VLK system images, which are among the easiest to find on the Internet.
