Pi 4: Can we **please** have an rtc included?

Currently, installing any rtc on the Pi, even the 3B+, and getting the software right is "a dog's breakfast". There are so many articles about how to do it, files to edit, and I've not found a single one which entirely documents the process on 3B+ / stretch lite. I'm certain this would be solved by ...

Re: Raspbian Jessie Lite - missing bits!

. . . Python 2 vs python 3 is a such a mess it makes the language look even more stupid, how they can make a new version that's incompatible with the old version is beyond belief. That's the thing that's "odd". Absolutely agree, that's why weewx (weather software) uses only 2.6 or 2.7 and if it's m...

Re: USB boot, PI3B+: followed instructions, doesn't work

You don't need to set the OTP bit on the 3B+, it's set in the factory as standard. If I used Windows, I'd use Etcher to write the image file to the USB stick, as it is easier to use than the old Win32 Disk Imager program. Not all USB devices are compatible with the USB boot on the Pi, but I have fo...

I have a 3B+. Wrote the latest raspbian lite (2018-11-13-raspbian-stretch-lite.img -- it's for a headless operation) to a SD card, boots up fine, set the OTP bit and vcgencmd shows 17:3020000a.
