I come up with way more ideas than I can work on, and that's okay. That's good. It means I can always skim the top for interesting things, and it's fine if things overflow as long as the important stuff stays in the funnel. I'm experimenting with more ways to keep things flowing.

I usually come up with lots of ideas and then revisit my priorities to see if I can figure out 1-3 things I'd like to work on for my next focused time sessions. These priorities are actually pretty stable for the most part, but sometimes an idea jumps the queue and that's okay.

There's a loose net of projects/tasks that I'm currently working on and things I'm currently interested in, so I want to connect ideas and resources to those if I can. If they aren't connected, or if they're low-priority and I probably won't get to them any time soon, it can make a lot of sense to add quick notes and pass it along.

For things I want to think about some more, my audio braindumping workflow seems to be working out as a way to capture lots of text even when I'm away from my computer. I also have a bit more time to sketch while waiting for the kiddo to get ready for bed. I can use the sketchnotes as outlines to talk through while I braindump, and I can take my braindumps and distill them into sketches. Then I can take those and put them into blog posts. Instead of getting tempted to add more and more to a blog post (just one more idea, really!), I can try wrapping up earlier since I can always add a follow-up post. For some things, making a video might be worthwhile, so smoothing out my workflow for creating a video could be useful. I don't want to spend a lot of time filing but I still want to be able to find related notes, so automatically refiling based on tags (or possibly suggesting refile targets based on vector similarity?) might help me shift things out of my inbox.

I'm generally not bothered by the waste of coming up with ideas that I don't get around to, since it's more like daydreaming or fun. I sometimes get a little frustrated when I want to find an interesting resource I remember coming across some time ago and I can't find it with the words I'm looking for. Building more of a habit of capturing interesting resources in my Org files and using my own words in the notes will help while I wait for personal search engines to get better. I'm a little slow when it comes to e-mails because I tend to wait until I'm at my computer–and then when I'm at my computer, I prefer to tinker or write. I occasionally redo things because I didn't have notes from the previous solution or I couldn't find my notes. That's fine too. I can get better at taking notes and finding them.

So I think some next steps for me are:

• Post more toots on @sachac@emacs.ch; might be useful as a firehose for ideas. Share them back to my Org file so I have a link to the discussion (if any). Could be a quick way to see if anyone already knows of related packages/code or if anyone might have the same itch.
• See if I can improve my braindumping/sketch workflow so that I can flesh out more ideas
• Tweak my video process gradually so that I can include more screenshots and maybe eventually longer explanations

I received a Google Open Source Peer Bonus for my contributions to GNU Emacs, which was a pleasant surprise. Thanks!

I'm thinking of ways to reinvest the ~USD 250 award into Emacs and the community to see what a little money earmarked for that could do. People have already donated enough to EmacsConf to cover hosting costs, so that's all sorted out. People have also already sent me more than enough to cover my hosting costs using my ancient pay-what-you-want resources. I wonder how I could use the money to help me make more blog posts and videos.

Speech recognition: Paying for cloud usage will let me do tiny experiments without upgrading my X230T¹ for now. I could start with speech recognition as a way of fleshing out ideas and getting them into text faster. Deepgram charges USD 0.0048/min for batch-processing with Whisper Large and USD 0.0059/min for streaming with their Nova-2 model, so that's… umm… ~860+ hours I could process. Over the past couple of weeks of experimenting with this idea, I've recorded about 1-2 hours of audio braindumps a day, so that's still well over a year of being able to play around with this. (And actually I still have USD ~187 of free trial credits with them, so…)

AI: I might also be able to use AI for outlining/summarizing/cleaning up my audio braindumps. I just have to figure out the right prompts for ChatGPT. Here's one I've been experimenting with so that I can get things into roughly an Org Mode format while still letting me easily look things up in the transcript:

Drawing: The kiddo uses the iPad a lot for reading, but maybe I can squeeze in some time to tinker around with different apps for drawing and animation.

Video editing: Maybe I can learn more about video editing or figure out what gear makes sense to add to my setup.

If you have other suggestions for low-cost experiments that might pay off in terms of making more useful blog posts or videos, I'd love to hear them!

At some point during the conversion of my blog from Wordpress to 11ty, I wanted to change my sketch links to use a custom shortcode instead of referring to the sketch in my old wp-uploads directory. Because Wordpress changed the filenames a little, I used the ID at the start of the filename. I forgot that many of my filenames from 2013 to 2015 just had the date without a uniquely identifying letter or number suffix, so many old references were ambiguous and my static site generator just linked to the first matching file. When I was listening to my old monthly reviews as part of my upcoming 10-year review, I noticed the repeated links. So I wrote these functions to help me find and replace markup of the form sketchLink "2013-10-06" with sketchLink "2013-10-06 Daily drawing - thinking on paper #drawing", replacing references to the same date with the next sketch in the list. I figured that would be enough to get the basic use case sorted out (usually a list of sketches in my monthly/weekly reviews), taking advantage of the my-list-sketches function I defined in my Emacs config.

(defun my-replace-duplicate-sketch-list-references ()
  (interactive)
  (goto-char (point-min))
  (let (seen)
    (while (re-search-forward "sketchLink \\\"\\([0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]\\)\\\""
                              nil t)
      (if (assoc (match-string 1) seen)
          (setcdr (assoc (match-string 1) seen) (1+ (assoc-default (match-string 1) seen)))
        (setq seen (cons (cons (match-string 1) 1) seen))))
    (mapc (lambda (entry)
            (goto-char (point-min))
            (mapc (lambda (sketch)
                    (if (re-search-forward (format "sketchLink \\\"\\(%s\\)\\\""
                                                   (regexp-quote (car entry))) nil t)
                        (replace-match (save-match-data (file-name-sans-extension sketch))
                                       nil t nil 1)
                      (message "Skipping %s possible ref to %s"
                               (buffer-file-name)
                               sketch)))
                  (my-list-sketches (concat "^" (regexp-quote (car entry))) nil '("~/sync/sketches"))))
          seen)))

Sometimes I needed to delete the whole list and start again:

(defun my-insert-sketch-list-between (start-date end-date)
  (insert
   (mapconcat
    (lambda (f)
      (format "<li>%s sketchLink \"%s\" %s</li>\n"
              (concat "{" "%")  ; avoid confusing 11ty when I export this
              (file-name-sans-extension f)
              (concat "%" "}")))
    (sort (seq-filter
           (lambda (f) (and (string< f end-date) (not (string< f start-date))))
           (my-list-sketches nil nil '("~/sync/sketches")))
          'string<)
    "")))

I used find-grep-dired to search for sketchLink \"[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]\" and then I just used a keyboard macro to process each file.

Anyway, really old monthly reviews like this one for October 2013 should mostly make sense again. I could probably pull out the correct references from the Wordpress database backup, but what I've got is probably okay. I would probably have gotten much grumpier trying to do this without Emacs Lisp. Yay Emacs!

I sometimes want to move the Org source for my blog posts to the same directory as the 11ty-exported HTML. This should make it easier to update and reexport blog posts in the future. The following code copies or moves the subtree to the 11ty export directory.

(defun my-org-11ty-copy-subtree (&optional do-cut)
  "Copy the subtree for the current post to the 11ty export directory.
With prefix arg, move the subtree."
  (interactive (list current-prefix-arg))
  (let* ((file-properties
          (org-element-map
              (org-element-parse-buffer)
              'keyword
            (lambda (el)
              (when (string-match "ELEVENTY" (org-element-property :key el))
                (list
                 (org-element-property :key el)
                 (org-element-property :value el)
                 (buffer-substring-no-properties
                  (org-element-property :begin el)
                  (org-element-property :end el)))))))
         (entry-properties (org-entry-properties))
         (filename (expand-file-name
                    "index.org"
                    (expand-file-name
                     (assoc-default "EXPORT_ELEVENTY_FILE_NAME" entry-properties)
                     (car (assoc-default "ELEVENTY_BASE_DIR" file-properties))))))
    (unless (file-directory-p (file-name-directory filename))
      (make-directory (file-name-directory filename) t))
    ;; find the heading that sets the current EXPORT_ELEVENTY_FILE_NAME
    (goto-char
     (org-find-property "EXPORT_ELEVENTY_FILE_NAME" (org-entry-get-with-inheritance "EXPORT_ELEVENTY_FILE_NAME")))
    (org-copy-subtree 1 (if do-cut 'cut))
    (with-temp-file filename
      (org-mode)
      (insert (or
               (mapconcat (lambda (file-prop) (elt file-prop 2))
                          file-properties
                          "")
               "")
              "\n")
      (org-yank))
    (find-file filename)
    (goto-char (point-min))))

Then this adds a link to it:

(defun my-org-export-filter-body-add-index-link (string backend info)
  (if (and
       (member backend '(11ty html))
       (plist-get info :file-name)
       (plist-get info :base-dir)
       (file-exists-p (expand-file-name
                       "index.org"
                       (expand-file-name
                        (plist-get info :file-name)
                        (plist-get info :base-dir)))))
      (concat string
              (format "<div><a href=\"%sindex.org\">View org source for this post</a></div>"
                      (plist-get info :permalink)))
    string))

(with-eval-after-load 'ox
  (add-to-list 'org-export-filter-body-functions #'my-org-export-filter-body-add-index-link))

Then I want to wrap the whole thing up in an export function:

(defun my-org-11ty-export (&optional async subtreep visible-only body-only ext-plist)
  (let* ((info (org-11ty--get-info subtreep visible-only))
         (file (org-11ty--base-file-name subtreep visible-only)))
    (unless (string= (plist-get info :input-file)
                     (expand-file-name
                      "index.org"
                      (expand-file-name
                       (plist-get info :file-name)
                       (plist-get info :base-dir))))
      (save-window-excursion
        (my-org-11ty-copy-subtree)))
    (org-11ty-export-to-11tydata-and-html async subtreep visible-only body-only ext-plist)
    (my-org-11ty-find-file)))

Now to figure out how to override the export menu. Totally messy hack!

(with-eval-after-load 'ox-11ty
  (map-put (caddr (org-export-backend-menu (org-export-get-backend '11ty)))
           ?o (list "To Org, 11tydata.json, HTML" 'my-org-11ty-export)))

Both Google Cloud Vision and SuperNote's new handwriting recognition handle my print fine. Neither handle columns the way I'd like, but to be fair, I'm not really sure how I want columns and wrapping handled anyway. I can always experiment with the standard use-case: one column of text, to export as text (with perhaps the occasional sketch, which I can crop and include).

If I can get the hang of writing my thoughts, then it turns some of those bedtime hours into writing hours. Writing by hand feels slow and linear, but it's better than nothing, and thinking takes most of the time anyway. While speech recognition feels like it might be faster in short bursts, I don't have a lot of "talking to myself" time (aside from sleepy brain dumps), and my workflow for processing audio is still slow and disjointed. I can't type on my phone because then A- will want to be on a screen too. I'm glad e-ink devices are different enough not to trigger her sense of unfairness, although sometimes she does ask if she can do mazes or connect-the-dots. Then I switch to knitting until it's really really time to go to bed.

I'm slowly figuring out my workflows for experimenting with and writing about code. Naturally, that's a little more challenging to write about by hand, but I could draft the context. I can think through life stuff too, and maybe look into saving more notes in my Org files.

I've experimented with handwritten blog posts before. Now that I have a little more time to tweak my workflow and think thoughts, maybe I'll get the hang of them!

It looks like the Supernote's real-time recognition is pretty accurate for my handwriting, getting the text out of multiple pages is pretty straightforward.

Here's the raw TXT output from the Supernote.

Here's what it took to edit it into the first part of this post - just adding line-breaks and fixing up some words:

Source images

[[

If I add more lines between paragraphs when writing, I might be able to skip adding them in the text export.

For comparison, here's the text output from Google Cloud Vision.

I'm leaning towards SuperNote's recognition results for long text, although I don't get access to the confidence data so I'll probably just have to delete the misrecognized text if I include sketches.

I'd like to write about code more often. It's easier for people to try out ideas if they can copy the code without fiddling with selecting the text, especially on mobile browsers, so "Copy code" buttons on source code blocks would be nice. I used this tutorial for adding code buttons as a basis for the following CSS and JS code.

First, let's add the buttons with Javascript. I want the buttons to be visible in the summary line if I'm using the <details /> element. If not, they can go in the div with the org-src-container class.

/* Start of copy code */
// based on https://www.roboleary.net/2022/01/13/copy-code-to-clipboard-blog.html
const copyLabel = 'Copy code';

async function copyCode(block, button) {
  let code = block.querySelector('pre.src');
  let text = code.innerText;
  await navigator.clipboard.writeText(text);
  button.innerText = 'Copied';
  setTimeout(() => {
    button.innerText = copyLabel;
  }, 500);
}

function addCopyCodeButtons() {
  if (!navigator.clipboard) return;
  let blocks = document.querySelectorAll('.org-src-container');
  blocks.forEach((block) => {
    let button = document.createElement('button');
    button.innerText = copyLabel;
    button.classList.add('copy-code');
    let details = block.closest('details');
    let summary = details && details.querySelector('summary');
    if (summary) {
      summary.appendChild(button);
    } else {
      block.appendChild(button);
    }
    button.addEventListener('click', async() => {
      await copyCode(block, button);
    });
    block.setAttribute('tabindex', 0);
  });
}
document.addEventListener("DOMContentLoaded", function(event) { 
  addCopyCodeButtons();
});
/* End of copy code */

Then we style it:

/* Start of copy code */
pre.src { margin: 0 }
.org-src-container {
    position: relative;
    margin: 0 0;
    padding: 1.75rem 0 1.75rem 1rem;
}
summary { position: relative; }
summary .org-src-container { padding: 0 }
summary .org-src-container pre.src { margin: 0 }
.org-src-container button.copy-code, summary button.copy-code {
    position: absolute;
    top: 0px;
    right: 0px;
}
/* End of copy code */

Someday I'll figure out how to make it easier to tangle things to the post's directory and make the file available for download. In the meantime, this might be a good start.

I want to make it easier to process the sketchnotes I make on my Supernote. I write IDs of the form yyyy-mm-dd-nn to identify my sketches. To avoid duplicates, I get these IDs from the web-based journaling system I wrote. I've started putting the titles and tags into those journal entries as well so that I can reuse them in scripts. When I export a sketch to PNG and synchronize it, the file appears in my ~/Dropbox/Supernote/EXPORT directory on my laptop. Then it goes through this process:

• I use Google Cloud Vision to detect handwriting so that I can find the ID.
  • I retrieve the matching entry from my journal system and rename the file based on the title and tags.
  • If there's no matching entry, I rename the file based on the ID.
• If there are other tags or references in the sketch, I add those to the filename as well.
• I recolor it based on the tags, so parenting-related posts are a little purple, tech/Emacs-related posts are blue, and things are generally highlighted in yellow otherwise.
• I move it to a directory based on the tags.
  • If it's a private sketch, I move it to the directory for my private sketches.
  • If it's a public sketch, I move it to the directory that will eventually get synchronized to sketches.sachachua.com, and I reload the list of sketches after some delay.

The following code does that processing.

It uses this script I wrote to recolor my sketches with Python.

I'm contemplating writing some annotation tools to make it easier to turn the detected text into useful text for searching or writing about because the sketches throw off the recognition (misrecognized text, low confidence) and the columns mess up the line wrapping. Low priority, though.

My handwriting (at least for numbers) is probably simple enough that I might be able to train Tesseract OCR to process that someday. And who knows, maybe some organization will release a pre-trained model for offline handwriting recognition that'll be as useful as OpenAI Whisper is for audio files. That would be neat!
