You’ve heard it here before Harvard Business Review noticed:
@asymco & Judd diving deep into iPhone disrupting surgery navigation. With Dr. John Dorman and his Boltnav. On #asymetric, using #jtbd #Clay, #lowend and much more from the #disruption theory playbook. Next: Apple Vision Pro.
Delightful and inspiring! https://podcasts.apple.com/cz/podcast/asymetric/id1565557473?i=1000701232530
@bohwaz @punkfairie @ajsadauskas @JessTheUnstill @tomiahonen That's exactly the problem, cuz #KaiOS nee #FirefoxOS was a good and solid basis not just for #LowEnd-Devices but could've been excellent for a more #secure mobile OS, as it has good potential for #sandboxing and #KISS-principle'd #Apps that are lean and efficient.
Noone's gonna build an #App for a platform that is essentially a rounding error from the start!…
I've yet to see any #GPU at #MSRP in #Germany!
Worse there ain't even #LowEnd [< €100] or actual #MidRange [€250 - €500] cards available at MSRP!
This #ePaper seems to have 7 internal LUT sets for different temperatures. At 20'C refresh takes 4 secs. By fixing temp sensor to > 50'C, refresh takes 3.5 secs and there's no difference in picture.
I copied this "fast" table and started reducing iterations and frame counts so that picture quality still remains intact.
I've now reached < 1 s refresh, even for the full 648x480 and it still looks very nice. And now it's fast enough for simple #Linux terminal use!
Little progress today but still: Dumped the OTP table data from e-paper which helped a lot. In read direction, these things lack MISO pin so #Linux spidev can't read anything but I was able to do it with GPIO bit-bang from userspace.
So I have a copy of LUT data and I'm now able to modify and re-load it back to device. There's a baseline and method for the optimization.
A crucial document is UC8179 doc that documents the OTP data.
This week's #ePaper #hacking status: Got partial updates working nicely (pixel-wise) on 15€ unbranded 5.83" WFT0583CZ61. It's just as slow as full refresh, but limits flickering to the updated area, like a single 8x16 char, so the other part of the screen remains readable during refresh.
Now I try to make custom LUTs to make it faster. Nice; all registers are documented but no mention about operation principle whatsoever. Typical trial-and-error #Linux driver programming.
Today I'm testing my #8086 emulator running #DOS on a 10€ #RISC-V computer running #Linux.
Plenty of speed with negligible power consumption! Pretty impressive and way better than any RPi model. This board would be ideal for running a headless #retrocomputing telnet BBS.
Got my first #RISCV computer - LicheeRV Nano w/64-bit CPU, 256 MB RAM, Ethernet, UART, SD card slot etc at the 10 euro price point.
The vendor #Linux image is booting fine, but mainline experience is less smooth - I'm currently stuck at U-boot as the SD card fails to respond?! The first in-kernel DTS will be available in v6.13; maybe I'm just expecting too much at this point... though on U-boot side docs already say the SD should be functional.
Testing my touchscreen fixes for mainline kernel regressions on #Nokia 770 using #busybox shell and a virtual keyboard on framebuffer. The keyboard is very small but accurate enough for typing shell commands reliably with a pen.
The userspace binary size of my touch GUI is around 20 KB including bitmaps for the "keys" which I generated using the UNIX banner command and sed.
Building Perl 5 natively has been running for 2 days on OMAP1 w/32MB RAM, so I decided to look if there's something to optimize... It used to finish within a day. The compilation seems to proceed well, it's just slow because of swapping.
GCC 12.4 cc1 binary alone is around 22 megs. If I compile it with -Oz it shrinks almost 4 megs! On other binaries (like binutils) difference is not that big but still measurable. Going to check if this helps.
@ustralien Sadly no, and that's my big disappointment!
@frameworkcomputer decided to choose the #Apple-esque "flat cells below #trackpad" design in the unreasonable #THINN-ness race instead of doing what even the #EeePC and #Sony's #Vaio #P11Z did and have a slot at the back to chug in batteries!
Not that I don't like those #modules, but I'd rather wish for a "#THICC-er" device if that gets me essentials like #Ethernet, #USB-A & -C as well as a #TRRS #HeadphoneJack / #HeadsetJack.
That being said the #Framework is still by a long margin the "least #enshittified" device on the market, and same goes for the #Fairphone devices...
Not to mention they don't have an #UltraNav-Style #Trackpoint and I do use that instead of a Trackpad.
@gamingonlinux In fairness, Linux runs well on low-end devices. Embrace the #LowEnd
