pwinwood··on A fundamental principle of aeronautical engineering has been overturned
Same happened to me but I opened it in reader view in Firefox and it's fine!
pwinwood··on Ask HN: How many of you hold an amateur radio license in your country?
73 from G8KIG. Licensed in 1974.
pwinwood··on 2GB Raspberry Pi 5 on sale now at $50
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.
pwinwood··on DietPi – Lightweight justice for your SBC
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.
pwinwood··on CEO: Raspberry Pi stock to hit 1M units monthly, starting in July
SBitx ham radio transceiver. https://www.hfsignals.com/index.php/sbitx-v2/
pwinwood··on Project: Reviving an HP E-Vectra SFF Desktop PC
It is interesting to see the ESR (Equivalent series resistance) of the capacitors replaced too. This can be more significant than the absolute capacitance.
pwinwood··on The first Geely was a fake Mercedes-Benz E-Class based on a real Audi 100
The new Smart #1 EV is a joint venture between MB and Geely https://en.wikipedia.org/wiki/Smart_1
pwinwood··on Ask HN: Longevity for your parents, what to do?
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··on Raspberry Pi OS 32-bit vs. 64-bit Performance
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?
pwinwood··on RF Signal Generator
Quite a poor noise figure and bad spurs/harmonics for a signal generator.
pwinwood··on You can no longer bypass microsoft-edge:// links using apps like EdgeDeflector
Perhaps use "Image File Execution Options" on Microsoft Edge. Edge will never see the 'microsoft-edge://' links?

pwinwood··on BBC Micro at 40: How it inspired a generation of coders [video]
I don't think we could afford anything, but I could over a period of time build my own.
pwinwood··on QCovid: Personal Covid-19 risk calculator developed by Oxford University
During my Personal Trainer course a few years ago it was stated that an athletic build does not affect BMI
pwinwood··on Microsoft repo installed on all Raspberry Pi’s
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.
pwinwood··on Lua, a Misunderstood Language
> 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.

Yeah, with a small screwdriver.

pwinwood··on PoE for Raspberry Pi for under $2
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!
pwinwood··on Lipstick on a Pig a.k.a. the Raspberry Pi 3
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.
