Re: Tongue so far into cheek...

Surely the skill of the Judge comes into play and his judgement is subjective - is this more a test of the Judge or the machine?. What pre-knowledge does the judge have? Is the machine supposed to answer honestly or is it programmed/taught to purposely deceive? What role does the other participant ...

Re: VLSI Design (45nm/14nm nodes) with your Pi4 ?? (!)

Intel Pentium 4 in 2002 was made with a 130nm process node, so one would expect it to perform pretty poorly compared to a much more modern 28nm FPGA. Since 2002 is when I built a dual Opteron-240 system where the CPUs run at 1.4GHz, you can sort of see where that ought to be. Hmm... my RISC V proce...

Re: Yesterday, another 3 Pi4Bs 2GB died within 2 hours. Now it's 5 out of 20 dead.

So here's a wacky idea: counterfeit? Yes, that is wacky. Firstly it's pretty much impossible to by the Broadcom SoC used on the Raspberry Pi. Secondly, even if one could I very much doubt anyone could make Pi clones using them cheaper than they are already. There would be no profit in it. Of course...

Re: My pi3 keeps getting corrupted

Oddly enough for some time now I have been very cavalier about shutdown. I just yank the power whenever. In the last few years no SD corruption has happened. It's odd because back in the days of the first Pi it seemed SD cards would become corrupt if you looked at them the wrong way. Either the file...

I don't see any solder balls or obviously dry joints.

But some of that soldering does look pretty poor.

The sloppy flux residue looks like a repair job. Some of that solder looks like corrosion after the boards have been left out in a field for a year.

Re: GPIO fastest way to switch from OUTPUT to INPUT

When you say "script" I presume you are programming in Python or some such interpreted language.

If you are really sensitive to timing down to a handful of micro-seconds you will also have the ...

Re: Define output from terminal

Your question is not clear. The Pi itself cannot count time at all when it is powered off. That means that for it to know the time it has been powered off it will need some external hardware, with it's own battery or other power supply, to measure the down time. Or you could do it by making use of N...

Re: powering up peripherals from different power supply

Yes, you need to connect the grounds together. Other wise GPIO control signals have no reference zero to work against. Be sue that 5v cannot get back into your Pi GPIO pins. That rather depends on what devices you are conneting. Some external 5v devices may not work with the 3.3v logic levels of the...

Re: Get your Pi to fight COVID-19

Good you reminded me. My Pi went off the air when the WiFi router it talked to was decommissioned. My Jetson Nano went off the air when I installed a bigger SD card fresh OS. That only leave my big old industrial Intel computer munching on Corona. I should run around and spin them all back up again.
