WikiwideAnd now PDF reader is stuck. It has document X open, I click in File Manager for document Y to open, and PDF manager continues to display document X, not perturbed in the least.03:14
WikiwidePDF reader can go all-black for a while, so it does hear something from File Manager - it's not File Manager's fault.03:16
WikiwideAnd IRC is jumpy - on cellular Internet! At this rate, I will advocate for wooden buses with built-in Ethernet Internet - not that I know of any mobile phones with Ethernet built-in03:19
WikiwideAnd barcode readers don't read barcode from my phone's display. I have already done 200% or so zoom, set brightness to 5/5, the barcode occupies at least quarter of display - half of width and half of height...03:53
WikiwideThey are probably designed to work with AMOLED display, with super-transparent Gorilla/sapphire glass :-/03:53
WikiwideAt this rate, I would want to have a e-ink display for documents, barcodes and static images - low-power and I think that e-ink should be as readable as paper.03:54
* Maxdamantus got an e-ink device yesterday (Kobo)04:31
Maxdamantusdisplay seems quite nice.04:31
* Maxdamantus wants to see if he can get a usable terminal running on it at some point.04:32
WikiwideMaxdamantus: Sounds neat :-)07:20
KotCzarnymaxd: what soc?10:03
KotCzarnyas for terminal, you would have your own app, so refreshes wont drive it dead ;)10:04
KotCzarny*write your own app10:04
MaxdamantusDo modern e-ink displays have lifetime issues?10:21
MaxdamantusI imagine the main reason for having to write some special screen update mechanism is just to avoid ghosting.10:22
Maxdamantusas for continuous updates, I've noticed the included web browser supports canvas .. was able to run http://maxdamantus.github.io/recplay/ on it.10:23
KotCzarnythey are physical medium10:23
MaxdamantusSo is everything.10:23
KotCzarnyso i would assume they do, although it was more about refresh rate10:23
Maxdamantusincluding LCD.10:23
KotCzarnyimagine running dmesg on it10:23
KotCzarny;)10:23
DocScrutinizer05KotCzarny: on what? e-ink? X-D15:57
DocScrutinizer05there's even 2-color e-ink paper now. Black&red. I guess other colors exist as well15:59
DocScrutinizer05the "A4" size display allegedly (according to the fuzzy dadashit) takes up to 40 seconds for one full erase&scan16:00
DocScrutinizer05yep, forty. aka 2/3 of a minute16:01
KotCzarnywell, 16 level grayscale 1024x768 takes ~1s for full update17:40
KotCzarnywith reset17:40
KotCzarnyand color eink is just color filter applied on particular subpixels17:41
KotCzarnyso color is tripling horizontal resolution in terms of pixels to refresh17:41
