Some Ruby packages compromised - please check if you use these

Hi all

Just a note to anyone using Ruby:
https://github.com/rest-client/rest-client/issues/713

A backdoor in the code has been found to be running crypto-currency miners, but could be used with more malicious intent.

Re: Raspberry Pi 4 usb boot?

I quite like the way the Pi boots and the fact you can just copy the content of the two partitions to another card (or whatever) and it "just boots" without having to faff around with reinstalling boot sectors and boot loaders. This absolutely AMAZED me when I first tried it. It was an utterly jaw ...

Re: apache server stopped working

That would be difficult since the pi was build into the wall a few months ago. Can there be any reason why the problem occurs months after running smoothly? Or is there a way around this with settings or code? Thx ! There's no way around under-voltage warnings, I'm afraid. Your Pi isn't receiving t...

Re: [FeatureRequest]About menu item

You also don't get a splash screen if booting t o the command line. I was actually pondering this one. Perhaps a single script that collects system/hardware info usually requested on the forums, the output of which could also be in an "About" box in the menu? I know it's just another thing to maint...

Just to make it easy to find out what version of Raspbian is running without having to google to find out what terminal command is needed to get the info
Would it make sense to show what version of RPi it is running on as well? Two of the most requested bits of info on the forums.

Re: GLubyte and "+="

Hi PeterO

A little confused. You declare "step" as a GLubyte, but then go on to mention that a later function requires it to be a GLuint.
Wouldn't just declaring "step" as a GLuint help?

Re: No Preview Raspberry Pi 4

Make sure you are using HDMI-0 and not HDMI-1.
There were several reports of HDMI-1 not being active if HDMI-0 was not in use.

Also, don't know why the previous reply disappeared but try avoid using adapters.

Silly question, but I've had it happen to me in the past.
Have you looked at the alsa mixer (I think there's a CLI and GUI version) and checked that the volume on the source is not muted or turned all the way down?

What about a pet door with microchip reader?

Better yet, that one actually reads RFID as well...

Re: catPooPee

Not sure if micro-chipping your pets is a thing in the US, but there appear to be many micro-chip readers available on Amazon.
The microchip is usually implanted by syringe, but I suppose you could put it in a capsule on the collar.

They're definitely smaller than cattle tags though :D

Re: How can the memory size on Pi4B be reduced ?

Or assign the extra memory to the GPU (assuming there isn't a limit here).
It then won't be available to the CPU and Linux (unless your application uses the GPU obviously...)

Re: core_freq changes

The /boot/ directory on the Pi is mounted to a Windows (i.e. FAT) filesystem.
Just put your SD card into a windows machine, it should recognise this partition and let you edit the config.txt file

It looks like the former, which won't work.
