Very-low-field MRI scanners: from the ideal to the real permanent magnet array
Very-low-field MRIs are becoming increasingly popular due to their portability and adaptability to different environments. They are being successfully used for various clinical applications, leading to a paradigm shift in the way imaging care is typically performed. The development of low-cost MRI scanner prototypes began a few years ago, with some interesting and promising open-source projects emerging in both hardware and software design. Using permanent magnets (PMs) to generate the static m…

The Open Hardware Summit (@…) is looking for people to do talks, workshops and tabling for their open hardware projects in Berlin this year! Maybe one year it’ll be in Toronto? https://2026.oshwa.org

"One workload I now support would cost an estimated £6000 per month to run on one of the large cloud providers, which would allow me to purchase the actual hardware in use four times over every year. But “spinning up an instance” today using free credits means you can worry about that cost later, whereas ordering a box from Dell means waiting two to three business days by which time the hackathon is over."

Five Computers
There is no direct evidence that Thomas Watson, Sr. predicted in 1943 that there would be "a world market for five computers". First, he probably didn't know about computers back then: in the 1940s computers were classified research projects at the UK Government Code and Cipher School and the US Army, while Watson's IBM were famously involved with the other side during the war.
