Re: Painfully slow Pi

The latest graphics drivers are memory hungry, especially on pi with less than 1GB (pi zero)
I'd advise using legacy drivers for them.

Maybe try that on your 1GB pi4 ?

Goto raspi-config / advanced / enable legacy graphics

Re: Raspberry pi issues that were never fixed even for the new Pi 4

I can only imagine the OP has such a bad experience with dead pi's if: 1) He's running his pi units without a case - so any metal can potentially kill it. 2) using the GPIO hardware with lack of knowledge/safety. Some things might work for a while, then destroy pi. 3) using poor SD cards. They won't...

To answer my own question raspbian vs RPiOS above, I found this from Eben in the blog comments:
Eben wrote:[Raspberry Pi OS is ] just an overdue naming change to discriminate between Raspbian (the independent open source project) and the 32-bit images that Raspberry Pi builds on top of it.

Re: Pi Card Imager - android app prepares SD cards without PC

Android folders don't matter, pi will ignore them anyway.

But the app should put at least bootcode.bin and os folders on the card if you select NOOBS

SD cards of larger than 32GB may be formatted as exFAT, and pi needs it to be FAT32 to boot from.

Re: Old Raspberries...

Plenty of use left in them, mainly for non desktop duties.
As headless servers, or media players.

Remember pi zero is effectively same spec as pi 1 in terms of ram and cpu.

Re: Old SD (or microSD) cards

Old small SD are useful for old pi models to enable USB / network boot.

Just put the single file bootcode.bin on an otherwise empty SD card, and that enables them to boot from USB or network.

Re: WHY is ssh disabled by default..?

If you have an android phone you can put the micro sd card in that,
then use the files app to create a file called SSH.txt on the card.

(or create a pi sd card from scratch with the android app here:

Re: Why is NOOBs suggested to be used by Raspberry beginners?

It is a challenge posed by the Foundation to stop the unmotivated from using the Pi. To install either `NOOBS` or `Raspbian` you need access to a computer with a SD Card writer ; ` No computer needed, just an app on your phone - check my sig https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=1...

During this process, Raspberry Pi Imager also caches the downloaded operating system image – that is to say, it saves a local copy on your computer, so you can program additional SD cards without having to download the file again Note that it only stores the last one, then deletes it when you start...
