Quelle: meine eigene Handschrift – jedes Notizbuch, das ich seit September 2025 auf einem reMarkable 2-Tablet geschrieben habe, insgesamt 3.026 Seiten. Das Tablet speichert jeden Stiftstrich als Koordinatenliste in seinem eigenen .rm-Dateiformat, es handelt sich also um die Rohdaten des Stifts und nicht um ein Bild der Seiten.
Wie: Python mit der rmscene (https://github.com/ricklupton/rmscene)-Bibliothek, um die Striche zu analysieren, SQLite, um sie zu speichern, und Pillow, um die Heatmap zu rendern, indem die Strichlänge in einem feinen Raster über der Seite summiert wird. Das umgebende Layout ist nur HTML/CSS, Screenshot. Keine Diagrammbibliothek. Der Tintenabstand ist die summierte Punkt-zu-Punkt-Länge jedes Strichs. Ich habe es kalibriert, indem ich den Umfang einer Kreditkarte nachgezeichnet habe (ID-1-Standard, 85,6 × 53,98 mm) und es liegt innerhalb von ~1 %. Gelöschte Striche sind ausgeschlossen.
Ein paar Dinge können Sie auf der Karte ablesen: Auf dem hellen Fleck oben links schreibe ich den Titel auf jede Seite; Die horizontale Streifenbildung ist die Regellinienvorlage, auf der ich schreibe. und das schwache dreieckige Gitter unten ist ein einzelnes Gekritzel von einer Seite – es fällt auf, weil der untere Rand der Seite unverhältnismäßig weniger Tinte erhält als der obere (und das Ausfüllen dieses Gekritzels hat viel Arbeit gekostet, haha).
Es ist Teil eines kleinen Live-Dashboards, das ich für mich selbst erstellt habe (Tagessträhnen, Tageszeit, diese Heatmap): https://remarked.pavelj.com/public.html – Seien Sie vorsichtig, es wird auf einem 2011 Mac Mini selbst gehostet. Wenn es also nicht funktioniert, habe ich das Cloudflare-Caching durcheinander gebracht.

This is ridiculously interesting
Now this is beautiful data visualization! Thanks OP!
Are the triangles your doodling?
What causes those triangular formations?
At the end of every class does your professor tell you to draw the HSBC logo?
This is honestly fascinating, thank you for sharing. It reminds me of when I messed around with a heatmaps extension on a company’s website at an old job, something about heatmaps tickles a certain part of my brain.
How’s the writing experience on the remarkable 2?
I’m also curious about the file structure, is it nested? I’d like to get one to keep my thoughts organized.
Amazing, but also an indictment of lectures and university teaching content, I too found myself going to lectures and making only a few lines of notes and wishing I’d stayed in bed!
Am i the only one that got confused by the title? „pen landed“ is a synecdoche. I thought it meant a totally different thing. As in, you would lay your pen flat horizontally on a surface and record that. It would be more accurate to say it’s a heatmap of your handwritten notes.
Maybe you should have some kind of equalizing on the data? Because it’s weird that your triangles come from one page. They seem overrepresented across a 3000 page database.
Regardless, this is beautiful data. Pointless and elegant. Wonderfully fitting.
You wrote 3,000 pages of notes in a year?? The fuck
Edit: averaged out over a standard 2 semester university system that’s ~90 days of classes, depending. 30+ pages a day is mind boggling to me. Am I getting that right?
Which font are you using for the main text and little, semi-transparent capitalized titles?
You could frame that, it’s literally art. Kinda disappointing that the triangles are just from one page but still really interesting and beautiful.
I was about to ask about the schizophrenia writing at the bottom if it was words in those shapes lmao
Very interesting and looks great. Do you have one for an „average“ page, if that makes sense? It would fade away the doodle in the bottom.
That’s so cool! Could make a animated version of the heatmap from the beginning. I saw the When you write box so I guess you could even go by the exact time – I would lowkey watch that. You can post it on r/SideProject .
Cool visualization! Since you have the raw data, I’m curious: if you total the ink used on each of the first nine ruled lines, does the distribution look anything like Benford’s Law—roughly 30% on line 1, 18% on line 2, 12.5% on line 3, etc.? I realize Benford’s Law doesn’t technically apply here, nor should it, but the fading pattern made me wonder how closely they match.
Incidentally, how did you find the remarkable tablet? Would you recommend it?
Crazy that one page can totally change the heat map with those triangles
The vertical lines are interesting. Any idea if it’s from indenting or something?
I thought this was a cuneiform tablet at first.
Nice work though!
I was skimming through reddit posts and stumbled upon this. I thought this was a post about NVIDIA’s GPU announcement lol. Really great work on the visualization. If you search up „Blackwell Architecture“ on Google images you’ll see the similarity of it
What subjects were you taking? Primarily STEM, humanities, or a mix?
[What I learned in boating school is](https://preview.redd.it/i-tried-recreating-the-the-from-sponge-bob-v0-ua5uaaq0gilg1.jpg?width=582&format=pjpg&auto=webp&s=3a830e4421eae16ce0b4ce282c437b200c15df3b)
I know you said you’re in CS, but I wish you’d post this to r/engineeringstudents. This is the perfect example of the sort of personal project that is recommended aa nauseum to „get you noticed“, and also a perfect example of the sort of initiative and curiosity that employers are looking for. But half the students in that sub seem to have fallen into the trap of thinking it’s the project that is the thing instead of the motivations behind it. Which is kind of OK, I guess, because half of the hiring managers just see it as a box to check off as well, but this kind of nerdery is exactly what I see in my brightest classmates.
Awesome. How are you finding & using the Remarkable 2? I’ve been eying a „paper replacement“ tablet though I’ll be nowhere near 3000 notes in half a year.
Am I missing something? This is just how writing works.. top left to bottom right. Wouldn’t most people’s note books look the exact same..?
