OK so to be faiiiir: Boox has a (problematic) SDK that allows you to integrate with what I assume is the same underlying API.
I'll loop back to why it's problematic in the next posts, but see this video for why it doesn't even fix all of OneNote:

It's because in Boox's firmware (as of 3.2.2) they hardcode OneNote, WPS, and EverNote to use their inking stuff rather than the built-in stuff
...
Dead end. 😭

Giving GameActivity a shot to see if the bottleneck is JNI input throughput

Apparently 0.3ms still isn't fast enough...
And I don't think eInk needs 3000fps so maybe time to try a different approach...

Bought an eInk Android tablet (Boox) for a friend around Christmas.
While developing an app for it, we came to realize that only first-party drawing apps (using their C library) have acceptable latency.
This is what a stripped down Jetpack Ink API looks like on it:

I've been wanting an e-ink tablet to help me focus while doing writing...
But then keep realizing all of the problems that would arise (window management, code editing, et al)
So instead I wrote a shader for my Windows desktop that mimics the style.
Looks shockingly convincing to my eyes

🧵 1/6 `for` loops in JavaScript are more complex than you think they are.
Let's start with a basic `for (let i = 0;)`...
Here we can see it counting from 0 - 2.
But everything in the parens for the `for` loop aren't executed all-at-once.

I was just on the season 2 finale of @codetv.dev!
It's not out yet, but had an absolute blast with @jason.energy, my code partner @zeu.dev, and the rest of the crew!
Beyond excited for when the episode goes live - I'll share more then!

Most companies have similar business needs for their software, but not all needs are met equally
IE: Error handling. Critical for biz needs. Yet so many companies I've seen absolutely neglect it. Why? Not enough engineers focusing on that discipline
Get good at that stuff and you'll be unstoppable

Skeleton loaders are cool!
But after a bit of looking, I couldn't find an implementation in React that had the loading line persist across elements
So I built my own! It's framework agnostic & supports React/Vue
All cuz I got nerd sniped by a mockup from @pratti.bsky.social lol

most of this traffic is coming from "oslo" and is direct traffic...
do they not realize this is a static site?? 😵💫
