Over on the Creatures of Thought blog, is an excellent, detailed essay on how computers have been linked to education from the 1960s to the 1980s.

The belief that computers would revolutionize education took root long before the microcomputer era; it had spread rapidly across American universities in the 1960s. The political and technical moment were both ripe: the Soviet launch of Sputnik in 1957 and Lyndon Johnson’s Great Society programs both catalyzed massive new flows of federal money into education, and into educational research in particular.

Meanwhile, time-sharing, which allowed multiple users to simultaneously access a single large, expensive computer, made it conceivable to teach whole classrooms of students at once by computer (though this was still very expensive, given the price of computers at the time).

However confused the original purpose and function of classroom computers, they became by the mid-1980s an unquestioned necessity. That schools were obligated to expose their charges to the basics of the computer became an accepted fact-of-life of twentieth-century schooling.

This mirrored a broader trend of personal computing: in a handful of years it went from curiosity that large organizations ignored, to an experiment that a few early adopters within large organizations took up, to a requirement that large organizations controlled. Nothing better embodied this transformation than the IBM Personal Computer.

Raspberry Pi 4 connected to an HDMI display and a BME280 sensor via I2C. The display shows the Ubuntu Core logo during first bootup and installation.

Ubuntu Core is an OS intended for use on devices embedded within commercial products or industrial equipment. It’s very locked down by default. It runs on lots of different hardware, this new guide focuses on Raspberry Pi 3, 4, and 5 devices. It is a very different kind of OS than the traditional Raspberry Pi OS, which is aimed at students, hobbyists, and tinkerers. The locked down nature can make the development iteration cycle slower and more tedious than traditional Pi OS. Ubuntu Cores strengths really shine most after you’ve already got a project functioning how you want under a more traditional OS like Pi OS or Ubuntu Server/Desktop and you are ready to deploy somewhere remote.

The Ubuntu Core documentation describes the OS like this:

Ubuntu Core is an immutable and transaction-based version of Ubuntu that’s engineered for cloud, embedded, and IoT systems.

It provides an image-based deployment infrastructure with automatic updates for sandboxed applications, enabling the creation of production-ready systems with minimal attack surface and automatic rollback capabilities.

Ubuntu Core reduces the time to production by eliminating manual provisioning, ensuring systems remain secure throughout their lifecycle, and enabling rapid updates across fleets of devices at scale.

It is designed for embedded Linux developers, IoT device manufacturers, cloud-based applications, and organizations deploying embedded systems in robotics, automotive, signage, industrial automation, and IoT applications – from single devices to thousands in the field.

This new guide features pages covering installation, a sensor dashboard demo, and building custom snaps and images.

Five Adafruit microcontroller boards with built-in SD card slots: Memento camera board, PyPortal, Metro RP2350, Feather RP2040 Adalogger, and Adafruit Fruit Jam, displayed alongside several SD cards of various sizes.

This guide benchmarks SD card performance in CircuitPython across a range of boards, card tiers, and filesystems. The findings are straightforward: SDIO for bulk transfers, SPI for fast small writes. For max performance, pair a card over 32 GB (A2/U3 rated) with an exFAT filesystem.
