All 83 spiral journals have processed. I'm done now. Nearly a months worth of work.

re: E-ink Design Principles 

@dredmorbius from what I've seen, it seems like e-ink companies don't really care too much about e-ink. Which is kind of unfair, seeing as they control the e-ink.

E-ink Design Principles 

@zens My own set of e-ink design principles:

1. Persistence is free. Once set, the display will continue to show specific static content indefinitely, with no power applied.

2. Pixels are cheap. DPI is typically 200 or higher, devices well over 300 DPI are available, though not precisely common. This is equivalent to many laserprinter's dot resolution.

3. Paints are expensive. In terms of energy use (battery life), time, and disruption (display ghosting / flickering, varying with display mode), any screen changes impose technical or cognitive costs.

4. Refreshes are slow. Rather than 60--120 Hz, you're operating in the range of 0.5 -- 10 Hz. Most devices / modes can accomplish fairly rapid (> 4 Hz) updates, but that's not guaranteed.

5. Colors are very limited or nonexistent. There are colour devices, they're a small subset of the total, palettes are limited, and display characteristics worse than B&W (1/4 pixel density, slower refresh). Many devices offer a limited greyscale palette, ranging from 1--16 shades (1-4 bits). Line art works well, most raster images require dithering or halftones for best effect.

6. Pagination navigation is strongly preferred to scroll. Change the entire page in one fell swoop. It's much harder to regain reading point when scrolling in e-ink than it is with emissive displays. This means providing interfaces for paginated movement. Regions work better than gestures.

7. Reflective rather than emissive. You can't pour light into portions of your display, you can only remove it. Colour mixing is pigment, not light (if it exists at all). Readability increases with direct sunlight / bright ambient light. Many devices do have illumination (backlight / frontlight).

8. Touch / wacom may exist. Many devices incorporate a wacom layer and can use a stylus. Do with this what you can / may.

E-ink Design Principles 

@dredmorbius @zens these are great!

Faster e-ink refresh rates are possible and becoming more common. I have displays that work at 15hz, and I've seen proof-of-concept displays with even faster refresh rates.

Despite this being possible, I think aiming for an experience with a slower refresh rate is still better design because it will preserve the lifetime of the display.

not great pics bc I took them on the bus but the first pride whale is done! Customer wanted bi pride barnacles & the constellation Gemini included. very very fun.

@ta180m QWERTY, kind of? Apparently it was a layout designed for the typewriter to slow people down a little bit so they wouldn't jam it up.

I imagine building an intentionally slow (adversarial) keyboard layout is very similar to making a fast keyboard layout. Just inverted. There's room for creativity too (super heavy key switches, many modes, probabilistic hits, audio/visual distractions, etc).

@FiXato yup. That's the one. Will check that link out.

Damn, still thinking about that TASBot OOT video I watched today. I watched the whole hour in one sitting. And I don't even watch speedrun vids.

Once they are imported into the zet, a zetdoc can be dynamically restitched together and rendered as HTML. You see this towards the end of my notes on The Algorithm Design Manual. The weird jumble of letters like [guihokhak] are actually an abbreviated UUID for that particular snippet:

Zetdoc is a constrained markup format I have developed to write sequential chunks of ideas in an intermediate format, which can then be imported into my zettelkasten database:

It remains to be seen how useful this will be in the long term. My goal with zetdoc was to try and make my writing more granular, in order to help facilitate more interconnected ideas.

@penguin42 The initial results so far seem much clearer compared to that of a digital camera. Certainly better than something you'd casually take with your phone. It looks closer to something you'd get from a conventional scanner. For doing a handful of pages, it's quite fast and convenient.

One thing I've noticed from reviews is that it's possible to get weird scanning artifacts. So that's something to keep in mind. But it seems minor. The page size is limited to about US letter (8.5x11in). So that's something to factor in too.

For reference, over the past few months, I've taken photos of literally thousands of pages using an RX100 digital camera. I made a dedicated setup with controlled lighting, tripod, and external remote. That setup is much more streamlined, and I can move through journals much faster. The biggest issue is blur around some regions. if I used a glass plate to flatten things down, that would probably be minimized (this would make things much more cumbersome and slow). If I did more post-processing, I think I'd be able to get better quality output from the digital camera overall. But it does take a significant amount of time and effort.

@praxeology I went with the "IScan"?

haven't had this long enough to test out the battery life. will keep that in mind.

This "mobile" scanner seems like mostly promising solution for digitizing handwritten notes. Lightweight and small (good for travel), battery powered (2x AA), writes to microSD card, low-powered monochrome LCD display.

The only real weak point I've discovered is that it doesn't scan margins that well. That means in a way I'll have to handwrite notes *for* this thing, which I have mixed feelings about. I suppose big margins isn't terrible. If TeX can do it, so can I.
