Indeed, I use pen/pencil and (dot) paper. Different brain space.

A bunch of wimps for not going back to actual VT220 green phosphor terminals. Lol.

Indeed this is the way.

I also have variants of light and dark for different lighting conditions at night and day (particularly glare).

No, those are the same that have been around forever. They just have a new tool to "justify" their crappy behavior.

PC/GEOS v1.0 ran on an original IBM PC with 640K. The minimum for v1.2 was 1MB of RAM.

In terms of responsiveness, it was an interesting compare and contrast from the Sun workstations vs. the PCs running GEOS. Less mouse jitter is one memory (especially in comparison to those old Ultrix machines).

Yeah, PC/GEOS was built from the ground up to give that fully scalable "WYSIWYG" "Display Postscript" experience but the PC displays at the time weren't very good.

I remember learning about self-modifying assembly in the low level drawing code from JimDF.

Ah, I didn't realize that. PC/GEOS did in '89 or '90.

Lol. Migration of PC/GEOS to protected-mode 32-bit x86 was not some magical rubicon that wasn't foreseen.

Geoworks was doing well until its sales deals got utterly hosed by the Microsoft monopoly power play. That started a cascade of direct and indirect problems from both a technology and business perspective.

Yeah, it took way too long to prioritize and deliver a non-assembly development chain and opening that up to the public at large.

We cross-developed from Sun workstations to x86 PCs and quality of x86 native tooling wasn't nearly as good. But eventually building on x86 was actually quite a bit faster.

IME, Zed's real & perceived performance is way better than Sublime.

Disclaimer: I do work at Zed!

I was actually pretty surprised when we did our measurements, and would say those numbers don't match the perceived performance (oe the feed. I haven't experienced an app that feels more fluid for basic things like scrolling before Zed – Obviously I have bias, but that is my 2c!
