How You Can Promote Neuroplasticity in Your Brain

From positivepsychology.com

  1. Intermittent fasting (as noted earlier): increases synaptic adaptation, promotes neuron growth, improve overall cognitive function, and decreases the risk of neurodegenerative disease;
  2. Traveling: exposes your brain to novel stimuli and new environments, opening up new pathways and activity in the brain;
  3. Using mnemonic devices: memory training can enhance connectivity in the prefrontal parietal network and prevent some age-related memory loss;
  4. Learning a musical instrument: may increase connectivity between brain regions and help form new neural networks;
  5. Non-dominant hand exercises: can form new neural pathways and strengthen the connectivity between neurons;
  6. Reading fiction: increases and enhances connectivity in the brain;
  7. Expanding your vocabulary: activates the visual and auditory processes as well as memory processing;
  8. Creating artwork: enhances the connectivity of the brain at rest (the “default mode network” or DMN), which can boost introspection, memory, empathy, attention, and focus (see art therapy activities);
  9. Dancing: reduces the risk of Alzheimer’s and increases neural connectivity;
  10. Sleeping: encourages learning retention through the growth of the dendritic spines that act as connections between neurons and help transfer information across cells

The Navalmanack - Your Most Precious Resource


Naval's recommended reading ("Read what you love till you love to read"): https://www.navalmanack.com/navals-recommended-reading

From one of his favorites, https://meltingasphalt.com/crony-beliefs/

Consider the case of Acme Corp., a property development firm in a small town called Nepotsville. The unwritten rule of doing business in Nepotsville is that companies are expected to hire the city council's friends and family members. Companies that make these strategic hires end up getting their permits approved and winning contracts from the city. Meanwhile, companies that "refuse to play ball" find themselves getting sued, smeared in the local papers, and shut out of new business.

In this environment, Acme faces two kinds of incentives, one ..

If you tried reading that bit, you'll wish Kevin Simler (author of Melting Asphalt and also "The Elephant in the Brain") had read this by Scott Adams:

Business writing is about clarity and persuasion. The main technique is keeping things simple. Simple writing is persuasive. A good argument in five sentences will sway more people than a brilliant argument in a hundred sentences. Don’t fight it.

How You Can Squeeze Notebook LM


It claims to be happy with a URL. Try it and you find it doesn't do much - in fact, nothing at all..

So, what *can* you do?

Download the website - say it's one of those ancient online books with a TOC and Previous/Next buttons on each page. Use httrack.

Then, use this script (click to select) to (since Notebook LM takes markdown) pull the text from each page *meaningfully*. That is, you're saying Notebook LM is smart enough to make something out of headings. Else, you could just give it text. Ja? :)

Yes, you might need to ask chatGPT for a bash script to put all the text files into one - since N LM says something about a 50 file limit.

import sys import os import html2text def convert_html_to_text(input_path, output_path): # Read the HTML content from the input file try: with open(input_path, "r", encoding="utf-8") as infile: html_content = infile.read() except FileNotFoundError: print(f"Error: The file '{input_path}' was not found.") sys.exit(1) except Exception as e: print(f"Error reading the file '{input_path}': {e}") sys.exit(1) # Convert HTML to text text_maker = html2text.HTML2Text() text_maker.ignore_links = True # Optional: Ignore links in the output text = text_maker.handle(html_content) # Write the plain text to the output file try: with open(output_path, "w", encoding="utf-8") as outfile: outfile.write(text) print(f"Text successfully written to '{output_path}'.") except Exception as e: print(f"Error writing to the file '{output_path}': {e}") sys.exit(1) if __name__ == "__main__": # Ensure correct usage if len(sys.argv) != 3: print("Usage: python html2text_converter.py <input_file> <output_file_or_directory>") sys.exit(1) # Get command-line arguments input_file = sys.argv[1] output_arg = sys.argv[2] # Check if input file exists if not os.path.isfile(input_file): print(f"Error: The input file '{input_file}' does not exist.") sys.exit(1) # Determine output path if os.path.isdir(output_arg): # If output_arg is a directory, create the output file path output_file = os.path.join( output_arg, os.path.splitext(os.path.basename(input_file))[0] + ".md" ) else: # If output_arg is a file, use it directly output_file = output_arg # Perform conversion convert_html_to_text(input_file, output_file)

And then:

$ for fil in download_folder_name/www.websitename.com/somefolder/text/*.html ; do python3 script.py $fil destination_dir; done

Then, just upload the files from this destination directory and you're ready to start chatting with your data. It does work!

And then, there's xorpd - who also appears to be Israeli : https://www.xorpd.net/pages/x86_adventures.html ("You must do the exercises. You may say, 'I'm a fast learner and I can learn a lot by watching your lectures.' To this I would say, would you attempt to learn swimming by just watching lectures?"
