Re: "cannot open display" error with Pi4 without display

In addition to what pcmanbob said...... If your program requires desktop GUI then crontab @reboot can't be used as it will attempt to start your program before the desktop is ready. Of course it can be used. And people do it, every day of the week. It just requires some additional handling. I've ne...

Re: Access to /home/pi via SD card reader?

Two more points: 1) Yeah, I don't think you should expect to be able to fix the card to the point where you can boot from it. The objective at this point is just to recover what data you can recover. 2) If there is one particular file that you need (source file of some sort) and you know a word or p...

Re: Move OS back from USB to SD

RaspiOS (formerly Buster)
Don't you mean: formerly Raspbian?

It's still Buster.

Buster is, effectively, a version #, not a brand name. Raspbian/RaspiOS is the brand name.

Re: Understanding the udev rules

Note that you can't start a long running process from udev. As soon as the udev processing is complete EVERY task spawned by udev that's still running is killed (without prejudice). Indeed - this seems to be true and very vicious. I did some testing just now of udev and found that even after I'd ma...

Re: Access to /home/pi via SD card reader?

It is probably not a security issue; I think that is a red herring. Anyway, the best thing to do is to get a new SD card, install a new, fresh copy of Raspbian on it and get it booting on your Pi. Then, take the old SD card and put it in a USB SD card reader/writer. Insert that into a USB port on th...

Re: How many pi's do YOU own?

It is my understanding that nobody is supposed to own more than one PiZero.

Essentially, it is like certain drugs - you are allowed a small amount (in this case, 1) for personal use, but no more.

Re: Bash scripting library (pishlib)

Great. Thank you for the details.

Just one thing (yeah, here come the inevitable nitpicks): Wouldn't it be better to just have a function that returns the amount of memory (as a number) rather than having a series of separate, boolean checks for each possible size?

Re: Emergency Mode... :(

The most straightforward way is to do as you suggest, and use the facility provided by NOOBS (i.e., PINN) that allows you to re-install Raspbian and start over. Now, that's not to say it is the best way (because there are ways to do it, described below, that don't require to start over), but it is t...

It doesn't matter. The previous poster wants you to go out and spend more money (and time waiting for it to arrive) on something that almost certainly won't improve your situation.

Currently, when you stick in a USB device, you get a popup window asking you what you want to do.
