Installing Python 3.6.5 on macOS Mojave for Tensorflow

Since Tensorflow is not yet available via pip for Python 3.7 and pyenv can't build python on the latest macOS, let's install 3.6.5_1 via homebrew and use it in conjunction with pyenv to create an enclosed environment that will use 3.6 only when we need it:

brew unlink python
brew install --ignore-dependencies https://raw.githubusercontent.com/Homebrew/homebrew-core/f2a764ef944b1080be64bd88dca9a1d80130c558/Formula/python.rb
brew switch python 3.7.2_1

Install pyenv if you haven't already, we'll use it to switch to 3.6.5 only when we need it (e.g. jupyter), leaving the latest Python from homebrew as default release (e.g. 3.7.2_1):

brew install pyenv

pyenv rehash

C.H.I.P.

Just use nmtui.

Use your old Ubuntu Mate 16.04 SD from a Rpi3 with a new Rpi3 B+

Yes! You can reuse your old Ubuntu Mate 16.04 installation from a Raspberry Pi 3 with a new B+.

Trying to boot the B+ with the old SD without modifications, will result in the rainbow screen with thunderbolt screen showing up.

  1. From your old Rpi, update the firmware(kernel.img&co) on the boot partition running sudo rpi-update. This will be enough to boot on the B+ but the wireless card will still not work.

  2. Set a country code for the wireless adapter in your wpa-supplicant.conf (usually under /etc/wpa-supplicant/) adding country=GB.

  3. Get all the files contained in https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm and copy them over the content in /lib/firmware/brcm. This will add a few new and updated drivers for the B+ wireless adapter.

Building a cross-compiling toolchain for Swift 3.0.2 on Raspbian with working SPM

To build a Raspbian toolchain for Swift 3.0.2 a few things need to be changed in the original guide.

Download the Swift 3.0.2 packages instead of the 3.1.1 ones:

curl -o /tmp/swift-3.0.2-RPi1Zero-RaspbianNov16.tgz  https://www.dropbox.com/s/dkrkt9ht1c3hog2/swift-3.0.2-RPi1Zero-RaspbianNov16.tgz
curl -o /tmp/swift-3.0.2-RELEASE-osx.pkg https://swift.org/builds/swift-3.0.2-release/xcode/swift-3.0.2-RELEASE/swift-3.0.2-RELEASE-osx.pkg

Launch the script with these parameters:

How to enable the SD card insertion detection on a Banana Pi M3

Once you dd the image they provide, you'll notice that you can only boot from eMMC when the SD is not inserted and if you inser it after boot, the system doesn't even discover the devices.

There is an easy fix for this.

At boot, uBoot looks for /boot/bananapi/bpi-m3/linux/uEnv.txt and loads /boot/bananapi/bpi-m3/linux/script.bin that contains additional configuration, like how to manage the SD, in binary format.

You just need to follow a few simple steps to enable SD discovery after boot (there is a way to boot from the boot partition on the SD and then load the OS from eMMC but I didn't have time to experiment with that).

How to install ubuntu mate on an SD for RaspberryPi

Install xz with homebrew:

brew install xz

Insert the SD and get the device name for the SD with df:
