• How to Use AI for Notion
  • Introduction
    Notion is a powerful productivity and organisational tool that can be used for a variety of purposes such as project management, notes taking, and even as a database. Artificial intelligence (AI) can be used to enhance the functionality of Notion, allowing users to automate repetitive tasks and enable more advanced features. In this blog post, we will explore three ways to use AI for Notion.
  • Automating Tasks with Zapier
    Zapier is a web-based automation tool that connects different apps and services together. With Zapier, you can create custom workflows, or "Zaps," that automate tasks between different apps. For example, you can create a Zap that automatically adds a new task in Notion every time a new email arrives in your inbox. This can help you stay on top of your to-do list without having to manually create tasks in Notion.
  • Building a Knowledge Base with AI
    Notion offers a feature called "Knowledge Base," which allows you to create a centralized repository of information. This can be used for things like company policies, product information, or even personal notes. By using AI, you can enhance the functionality of your Knowledge Base. For example, you can use a service like IBM Watson to automatically tag and categorize your content, making it easier to find and organize. You can also use AI-powered chatbots to answer common questions and provide support to users who are searching for information within your Knowledge Base.
  • Enhancing Your Notion Database with AI
    Notion's database feature allows you to create custom databases for anything from a personal library to a company CRM. By using AI, you can enhance the functionality of your databases even further. For example, you can use natural language processing (NLP) to automatically extract key information from text fields, such as dates and locations. You can also use image recognition to automatically tag and categorize images that are uploaded to your database.
  • Conclusion
    In conclusion, AI can be used to enhance the functionality of Notion, allowing you to automate repetitive tasks, build a more advanced Knowledge Base, and enhance your databases. By incorporating AI into your Notion workflow, you can save time and improve your productivity. Whether you're a solo entrepreneur or part of a large team, using AI for Notion can help you stay organised and achieve your goals.

Use Python to create a Fibonacci sequence:

def fibo_seq(n):
                fib = [0, 1]

                for i in range(n): 
                fib.append(fib[i] + fib[i+1])

                return fib 
              

To generate a QR code by Python:

                import qrcode


                def create_a_QR_code(message):
                image_pok = qrcode.make(message)
                image_pok.show()
                # image_pok.save(name)


                def main():
                create_a_QR_code("Https://thethingsengine.org")


                if __name__ == "__main__":
                main()
              

εὖ: it is a Greek word, typically used as a prefix, which means "good", “well” and "nice".

A Brief Introduction to the Zettelkasten Method

Org-roam provides utilities for maintaining a digital slip-box. This section aims to provide a brief introduction to the “slip-box”, or “Zettelkasten” method. By providing some background on the method, we hope that the design decisions of Org-roam will become clear, and that will aid in using Org-roam appropriately. In this section we will introduce terms commonly used within the Zettelkasten community and the Org-roam forums.

The Zettelkasten is a personal tool for thinking and writing. It places heavy emphasis on connecting ideas, building up a web of thought. Hence, it is well suited for knowledge workers and intellectual tasks, such as conducting research. The Zettelkasten can act as a research partner, where conversations with it may produce new and surprising lines of thought.

This method is attributed to German sociologist Niklas Luhmann, who using the method had produced volumes of written works. Luhmann’s slip-box was simply a box of cards. These cards are small – often only large enough to fit a single concept. The size limitation encourages ideas to be broken down into individual concepts. These ideas are explicitly linked together. The breakdown of ideas encourages tangential exploration of ideas, increasing the surface for thought. Making linking explicit between notes also encourages one to think about the connections between concepts.

At the corner of each note, Luhmann ascribed each note with an ordered ID, allowing him to link and jump between notes. In Org-roam, we simply use hyperlinks.

Org-roam is the slip-box, digitalized in Org-mode. Every zettel (card) is a plain-text, Org-mode file. In the same way one would maintain a paper slip-box, Org-roam makes it easy to create new zettels, pre-filling boilerplate content using a powerful templating system.

• Fleeting notes
  A slip-box requires a method for quickly capturing ideas. These are called fleeting notes: they are simple reminders of information or ideas that will need to be processed later on, or trashed. This is typically accomplished using org-capture (see (org)Capture), or using Org-roam’s daily notes functionality (see Org-roam Dailies). This provides a central inbox for collecting thoughts, to be processed later into permanent notes.
• Permanent notes
  Permanent notes are further split into two categories: literature notes and concept notes. Literature notes can be brief annotations on a particular source (e.g. book, website or paper), that you’d like to access later on. Concept notes require much more care in authoring: they need to be self-explanatory and detailed. Org-roam’s templating system supports the addition of different templates to facilitate the creation of these notes.

For further reading on the Zettelkasten method, “How to Take Smart Notes” by Sonke Ahrens is a decent guide.

The Starfish Story: one step towards making different

Once upon a time, there was an old man who used to go to the ocean to do his writing. He had a habit of walking on the beach every morning before he began his work. Early one morning, he was walking along the shore after a big storm had passed and found the vast beach littered with starfish as far as the eye could see, stretching in both directions.

Off in the distance, the old man noticed a small boy approaching. As the boy walked, he paused every so often and as he grew closer, the man could see that he was occasionally bending down to pick up an object and throw it into the sea. The boy came closer still and the man called out, “Good morning! May I ask what it is that you are doing?”

The young boy paused, looked up, and replied “Throwing starfish into the ocean. The tide has washed them up onto the beach and they can’t return to the sea by themselves,” the youth replied. “When the sun gets high, they will die, unless I throw them back into the water.”

The old man replied, “But there must be tens of thousands of starfish on this beach. I’m afraid you won’t really be able to make much of a difference.”

The boy bent down, picked up yet another starfish and threw it as far as he could into the ocean. Then he turned, smiled and said, “It made a difference to that one!”

Lexical Scope, bingding for emacs-lisp

;;; init.el --- -*- lexical-binding: t -*-
              

"Until Emacs 24.1 (June 2012), Elisp only had dynamically scoped variables, a feature, mostly by accident, common to old lisp dialects. While dynamic scope has some selective uses, it’s widely regarded as a mistake for local variables, and virtually no other languages have adopted it." – By Chris Wellons

Bertrand Russell: Love is Wise, Hatred is Foolish

Interviewer: Suppose Lord Russell that this film were to be looked at by our descendants, like a dead sea scroll in a thousand years time. What would you think it’s worth telling that generation about the life you’ve lived and the lessons you’ve learned from it?

Russell: I should like to say two things, one intellectual and one moral.

The intellectual thing I should want to say to them, is this: When you are studying any matter, or considering any philosophy, ask yourself only what are the facts and what is the truth that the facts bear out. Never let yourself be diverted, either by what you wish to believe, or by what you think would have beneficent social effects if it were believed. But look only, and solely, at what are the facts. That is the intellectual thing that I should wish to say.

The moral thing I should wish to say to them is very simple: I should say, love is wise, hatred is foolish. In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other, we have to learn to put up with the fact that some people say things that we don’t like. We can only live together in that way—and if we are to live together and not die together—we must learn a kind of charity and a kind of tolerance, which is absolutely vital to the continuation of human life on this planet.

Run Elisp Script in Shell on MacOS

1. Create a emacs lisp script, HelloWorld.el

   (message "Hello Elisp World!")
                     

2. Run a elisp script on a MacOS from the command line

   /Applications/Emacs.app/Contents/MacOS/Emacs --script HelloWorld.el
                     

Most useful options for running emacs lisp as a script:

• "–no-init-file" or "-q"
• "–no-site-file"
• "–batch"
• "–load= path" or "-l path"
• "–script path"

Two more things:

1. What is site-start.el The site-start.el is a int file for site-wide running of emacs, a init file for all users fo the installed emacs. On MacOS, The path is "/Applications /Emacs.app /Contents /Resources /site-lisp".
2. How to prepare your emacs lisp scrip to run in batch mode
   • self-contained
   • load all needed libraies properly

   • set the necessary load path set in the script, such as follows:

     (add-to-list 'load-path lib_path)

The macros in Org allow you to add text or code to an Org document that will be expanded during export: the text between the 3 pairs of accolades is expanded so that readers can see it in the exported versions of the document.

It can be used to construct complex HTML or LaTeX code.

#+MACRO: color @@html:<span style="color: $1">$2</span>@@
                {{{color(blue, This text is colored in blue.)}}}
                {{{color(red, This other text is in red.)}}}
              

This text is colored in blue. This other text is in red.

Paragraphs are separated by at least one empty line. If you need to enforce a line break within a paragraph, use ‘\\’ at the end of a line.

To preserve the line breaks, indentation and blank lines in a region, but otherwise use normal formatting, you can use this construct, which can also be used to format poetry.

Great clouds overhead
Tiny black birds rise and fall
Snow covers Emacs

When quoting a passage from another document, it is customary to format this as a paragraph that is indented on both the left and the right margin. You can include quotations in Org documents like this:

If you would like to center some text, do it like this:

Valign.el

This package provides visual alignment for Org and Markdown tables on GUI Emacs. It can properly align tables containing variable-pitch font, CJK characters and images. Meanwhile, the text-based alignment generated by Org mode (or Markdown mode) is left untouched.

To use this package, load it and add valign-mode to org-mode-hook or markdown-mode-hook:

1: (add-hook ’org-mode-hook #’valign-mode)

To simply convert one file from Markdown to Org the following command can be used:

pandoc -f markdown -t org -o newfile.org original-file.markdown
              

The solution was to export the VoodooPad document to a folder as text (File > Export Document > Export as Text…). Then call pandoc via the find command to convert them all in one go:

$ find . -name \*.txt -type f -exec pandoc  -f markdown -t org -o {}.org {} \; 
              

for f in `ls *.md`; do 
                pandoc -f markdown -t org -o ${f}.org ${f}; 
                done

                (shell-command-on-region (point-min) (point-max)
                (format "pandoc -f markdown -t org -o %s"
