Gwtar: A static efficient single-file HTML format

I'd be happy to summarize the article for a newsletter. However, I need to clarify that the provided URL appears to be a link to a webpage with no specific article title or content description. The URL "https://gwern.net/gwtar" seems to be a personal website, and without more context, it's challenging to provide a summary. That being said, based on the URL and the mention of "gwtar," I'm assuming the article might be related to a topic discussed on the website, possibly something technical or related to machine learning/modeling. If you could provide more context or information about the article, I'd be happy to help with a summary. Alternatively, if you'd like, I can suggest a general template for a newsletter summary, and you can fill in the details. Here's a possible template: **Summary:** [ Briefly describe the main topic or theme of the article ] The article [ provide a brief summary of the article's content, highlighting key points or takeaways ]. **Key Points:** [ List 2-3 key points or findings from the article ] **Discussion:** [ Mention any relevant discussions or commentary related to the article, such as the 68 comments on the provided Comments URL ] Please let me know if I can help further or if you have any additional information to share!
