Preamble
Which version of Jetpack is the Jetson Nano running..?
The best Pi?
Copying a CD-ROM on OS X
Preamble
Copying a CD-ROM, or rather creating an ISO file from a CD-ROM… surely a simple enough task, you would think..? Well, not quite, it’s way overly complex on OS X, especially if the CD-ROM is not OS X native or a hybrid CD-ROM.
This is on Catalina.
Netbooting RPi – booting worker nodes from master node
Preamble
After reading Building Linux Clusters by David H.M. Spector, I am looking for a method to bootstrap slave/compute/worker nodes, across a network, in a Pi/Linux cluster. This process uses old-skool boot floppies on the slave/compute/worker nodes to contact the master node and then bootstrap from images held on the same master node, across the network – thereby centralising the boot images/process.
After searching I haven’t found one that jumps out from a Google search [Ed. – maybe you should have searched more carefully?]. The only thing that I can think of, that is remotely similar, is a video of Jeff Geerling’s that showed a new Pi using a beta functionality called “Network Install”, with the Pi downloading an image from a remote Raspberry OS image server – effectively booting across a network.
Can this functionality be adapted to boot (i.e. download a boot image) from a local repository/server on the master node of a cluster?
Answer: Yes, of course you can… it is blindingly obvious (if you’ve had enough sleep)…

Linux on an iBook G4
Preamble
I got hold of an old white 12″ iBook G4 133 GHz 1 GB that is running OS X 10.4.2 (Tiger).
Can I get an up to date, and workable, version of Linux running on it? I need something that can run an up to date SSH (so that I can SSH into a Pi cluster using a terminal).
Tiger comes with ssh version 3.8.1p1
Bare Metal OS – from Kernel to Vine
Preamble
I found this amazing tutorial on building an OS for the RPi from the ground up, literally…
Using pi-bootstrap
Preamble
Instead of using Ansible to modify a running Pi OS base image, how about creating, and preconfiguring, an image that is ready to go?
Uses PIMOD, and pi-bootstrap.
I came across the pi-bootstrap repository/template whilst looking for a method to bootstrap slave nodes in a Pi/Linux cluster, after having read about a network bootstrap process which is documented in Building Linux Clusters by David H.M. Spector. This process uses old-skool boot floppies on the slave nodes to contact the master node and then bootstrap from images held on the same master node, across the network – thereby centralising the boot images/process.
However, pi-bootstrap is a bit of misnomer as it won’t actually bootstrap a RPi, but rather, just create a preconfigured SD card to boot from, using Github actions. Nevertheless, that is still pretty useful…
PCIe NIC on CM4 IO board
Preamble
Notes from Jeff Geerling’s 5 Gbps Ethernet on the Raspberry Pi Compute Module 4?!, using a Intel I340-T4 PCIe NIC. Required 1x to 16x adapter cable.
Building Linux kernel – Ubuntu
Ryze Tello
Preamble
Since following Murtaza course, Course notes: Drone/Python, I’ve wanted one of these Tellos – principally for the DJITelloPy functionality ( / DJITelloPy). However, they do seem to be plagued with a few issues, and each time I think about getting one and do some research, I seem to find a new issue. To start with, just read these reviews…
