OpenAI lets you download GPT instructions and execute arbitrary code in their containerized environment. This is not a bug. Ref #chatgpt #code-agents #github #prompt-engineering

BM25 works as follows: Ref
- For each query term in the query, sum up the product of:
  - Inverse document frequency = LN(% of docs without the query term + 1) -- with a small tweak
  - Term frequency = freq / (freq + k) -- where k is usually between 1.2 to 2. Returns 0-1 with diminishing frequency benefit
    - k is multiplied by Document length normalization = 1 - b(1- DocLength/AvgDocLength). Longer documents have larger k, dampening frequency benefits.
- Some implications:
  - The actual BM25 score has no meaning. It's just useful for ordering
  - BM25 scores for 2 queries can be compared ONLY IF the document sets don't change

jspm lets you generate import maps against any CDN.

You can click on htop columns on the terminal to sort by that column! Mouse events work on command line apps. Julia Evans

A HTML quine: A page that, when rendered as HTML, shows the HTML source code of the page! #github #html #web-dev

You can enable syntax highlighting just using fonts. Ref #github #html #markdown

HTML is all you need shows examples of using HTML for notebooks instead of Jupyter, Observable, etc. #html #markdown #web-dev

The problem with Accept headers is that you can't link to them. Simon Willison

DuckDB has an LLMs.txt. #database #github #llm-ops #markdown Today, 38 repos on GitHub support it

Style of writing impacts output style a lot. E.g. Adding an evil laugh makes Claude more creative. Ethan Mollick #markdown #write

For good structured mode output, we need good prompting. #ai-coding #code-agents #markdown #prompt-engineering
- Mentioning examples and schema and "JSON" helps. When providing examples, using (user, assistant) message pairs helps (I think it's because it's easier for the LLM to parse).
- Using a {reasoning, answer} schema (with reasoning first) helps. Make reasoning concise and relevant Ref Arxiv
- We already know code in JSON is not a great idea. Ref

Just adding 3 real examples and regurgitation helped GPT 4o play chess much better. Both techniques may have more general use in prompting. Simon Willison #prompt-engineering

Alt Text will very likely be a browser feature. It's important for the Alt text to flow as part of the content when listening to the page. Perhaps even become a part of the browser APIs like speechRecognition. #future #html #speech-to-text

Langchain suggests multiple levels of agentic behaviour. LLM Call < LLM Chain < LLM Rounter < State Machine < Autonomous Langchain #code-agents #llm-ops
