Same happened to me but I opened it in reader view in Firefox and it's fine!

I agree with you but the Raspberry Pi's USP is the GPIO interfacing capability and the community surrounding it. You don't get these things with a second hand computer.

Rather than using DietPi for my devices around my home I use Balena (balena.io), which seems to cover the same area. In addition it has a dashboard so I can see the status of the devices too. Balena is Docker based. No connection with Balena, just a happy user.

It is interesting to see the ESR (Equivalent series resistance) of the capacitors replaced too. This can be more significant than the absolute capacitance.

Currently a Back end C# Dev here, 65 year old, so not old yet, I also exercise regularly 2 * Body Pump, 3 * Body Combat, 2 * Sh'bam, 1 * Body Balance. I find the group exercise classes keep me sharp for work too.

pwinwood — Mon, 07 Feb 2022 18:05:26 +0000

Raspberry PI OS 32bit is compiled for ARMv6 to support the orginal Raspberry pi. I wonder what impact on benchmarks there would be compiling for ARMv7 hence only supporting Raspberry pi 2 and later?

Quite a poor noise figure and bad spurs/harmonics for a signal generator.

Perhaps use "Image File Execution Options" on Microsoft Edge. Edge will never see the 'microsoft-edge://' links?

I don't think we could afford anything, but I could over a period of time build my own.

pwinwood — Fri, 05 Feb 2021 13:28:58 +0000

If I was going to use a Raspberry Pi for commercial use I would want full control over the OS and use Open Embedded etc, just like I have done for NXP etc. That way I have full control over my system. I think the alternative of using Raspberry PI OS and the dependency on updates on Raspberry Pi and their suppliers is too risky. So this is a non-issue for me.

> PS: on Windows I highly recommend the ZeroBrane Studio IDE. It is really fantastic.

Recommended by me too. The ZeroBrane Studio IDE is cross platform running well on macOS and Linux.

Disclosure: I am the original author of wxLua which ZeroBrane Studio is built on.

I would put a suitable USB plug on it rather than wiring to the GPIO pins as I am certain in a rush I would plug it in wrongly damaging the Pi!

To start the ARM processor in aarch64 (64bit) mode is just a question of setting the flag in the arm control (arm_control=0x0200) register to 0x0200 in the config.txt. see the discussion at https://www.raspberrypi.org/forums/viewtopic.php?f=72&t=1379.... I don't think it will give much of a benefit over aarch32 mode (arm_control=0x0000) because of the limited memory.
