Oh no! I've just discovered that one of mine is black. Should I have a hissy-fit about this production flaw in my power supply?

I'm happily waiting for the usb boot software enhancement. No rush. When it comes. Thanks.

Re: The mystery of 3 dead pi4s

My 6 RPi's are working 24/7/365 and all are powered with small SMPS. They cost a few bucks. i.e for example: https://www.aliexpress.com/item/33027190392.html?spm=a2g0s.9042311.0.0.27424c4dDpoG7J Hmmm - how do you use something like that safely?

Re: raspbian hex editor

I tend to use vi and xxd:

vi as hex editor:

`:%!xxd` to switch into hex mode (without the ` of course)
When you're done hit escape again and type:
`:%!xxd -r` to exit from hex mode.

Re: Pi 4 - full specification of VideoCore 6

More, but incomplete. Always bothered me that Broadcom doesn't release public specifications. It's not like they've got any leading edge GPU tech to hide... AMD and Nvidia are way ahead on the compute engine front. I thought the thinking here was that this would run the risk of other manufacturers/...

I've yet to come across a decent editor for Linux.
For minor changes to smallish files this is often a nice workaround - vi as hex editor:

Re: running a webserver from Raspberry Pi (32 bit or 64?)

I may be missing something on your initial post, but if there are no scripts then surely you should be able to rename the files from .asp to .html and host them on any web-server.

I use Lighty (https://www.lighttpd.net/) on my Pi's. It's very light-weight.

I avoid using official RPi-power supply , because they are built for "just enough". HDD + SSD on USB ports plus camera, and you get "Undevoltage detected" (dmesg -T).
What do you use instead when you need more power overall but want something as reliable as the official PSU?
