The article mentions 32-bit Raspbian which is moving to 64-bit to better support the Raspberry Pi 4 with 8 GB of RAM. Both the RPi 3 and 4 have 64-bit support but earlier models, including the popular and still-on-sale Zero, do not support 64-bit. This platform will likely stick around for a long time; we need to continue to fix issues like this size_t/off_t one in s3fs:
We just got a raspberrypi 400 in the mail yesterday to use is a media center pc. From what I understand reading things, Netflix will only work on 32bit because ChromeOS is 32 bit and they steal the Widevine blob out of ChromeOS to make Netflix and Amazon Prime work.
The other kind of lame consequence of that is I have to use Chromium rather than Firefox, which irks me just a little.
Other than that, the RaspberryPi 400 is a really nicely put together little machine.
Not that it matters tons for a media center, but, for general knowledge:
Chromium variants with the Google removed or deactivated are both more secure AND private.
I think 32-bit is still recommended on most Rpi 4 installs, because of greater software compatibility (across the established ecosystem). So it's going to change slowly.
