Just came across this one-year-old comment of mine on a YouTube video
titled "The Coolest Netbook You’ve Forgotten About: The OLPC XO-1" when
someone commented on my comment about 2 hours ago. [Link to the video:

I thought that I'd share it all of you on the mailing list since it shows
that people are still excited to hear about the cool stuff that the people
here have built and the impact you're delivering each and every day. All of
you are awesome!
Sharing the whole YouTube comment transcript here, without any editing:

Hi, I'm from SugarLabs, the organisation that makes the software that OLPC
laptops (and a lot more devices) run on.
Happy to answer any questions. Please ask.

Do you know if the display is switching modes with the greyscale thing?
Very curious how the screen works

Have the laptops been upgraded over the years or have they stayed with the
same exact hardware as initially? Eg bigger storage, Ram, a touchscreen,
etc?

@generic Josh number 96 I have a better resource for you to read up on this
display:

It serves a good intro to the OLPC display.

@generic Josh number 96 Thanks for asking.
A kernel configuration file is used to select colour or grayscale
mode in the driver, and thus the display controller ASIC. This is in
the kernel sources.
The keyboard shim detects brightness control keys and manages the
backlight power. When the backlight is turned off, the grayscale mode
is enabled. When the backlight is turned on, the grayscale mode is
disabled. This is in the keyboard shim sources.
On the XO-1.75 and XO-4 models, a reverse biased red LED in the same
SMT package as the green storage LED is used as an ambient light
sensor. The power management daemon (powerd) detects high ambient
light and turns off the backlight and turns on the grayscale mode.
The backlight is turned off to save power, and increase running time
on battery. This is in the powerd sources.
However, without any change to backlight brightness or mode switching,
full sunlight does appear as greyscale, because the human eye can't
discern the small amount of colour emitted by the backlight compared
to the large amount of white light reflected from the sun.

@Alex The hardware has been regularly updated with release of newer models.
For example, XO-4 (the latest one) has a touchscreen variant and improved
hardware.

What engine is the SugarXO browser based on?

@Alex The simple browser also called browse activity is implemented using
HulaHop library and uses Gecko rendering engine(same as Firefox). Other
browsers available for XO laptops are Opera and Firefox. :)

@Alex these laptops are not underpowered, they're just aimed at children
who want to learn, and appropriately capable to do so. :)

Exactly why do you need a developer key to boot things other than official
OS builds, and why does it take 24 hours to get one?

@velleda because this was designed with security and antitheft in mind, and
it's pretty secure, along with being fun to play with.

Would it be interesting to switch OLPC to Silverblue/OSTree for increased
reliability and less required maintenance?

@TheSola10 Sugar OS is designed specifically with young children in mind.
All our decisions, designs, usability considerations are made with that
thing in mind. I don't think any other organisation would want to do that
with OS.

@NiggaNig420 TOONZ They're giving their best efforts to help. They may or
may not be part of Sugar Labs (and in their defence it's hard to verify),
but they are providing people with helpful answers, so please don't be so
rude!
