Re: Raspberry Pi 4 1 or 2GB

Honestly, get the 2GB if you intend to use Chromium for webbrowsing browsing and possibly Scratch3. EDIT, definitely get 2GB is you intend to use Scratch3, see the blog release post for why /EDIT That's if you can afford the £10 extra. Don't forget some shops may do discount for Jam, Makerspaces, ed...

Re: Raspberry Pi 4 temperature

I have just realised and appologies, if anyone reads my little work-through of using a SenseHAT (which might be more common again now the AstroPi challenge is back on). I had left my Pi at the basic 1.75GHz overclock. I'll have a look at the default speeds at some point for my own curiosity, but it ...

Re: Python in Raspbian Lite treats input() as a number.

As above, use Python3.
You fallen on the very very common confusion with having to type python3.

Though take what you have learned with you. If/when you come across Python2 only code.

Re: Raspberry Pi 4 temperature

Fans and thing are the way to go, it's what I use. It doesn't take much to keep it happy. (probably repeating myself ;-) now) But Fans and HATs * don't * go. The Pi4 is not edit overly /edit HAT friendly as heat build up under it of course. It's is very much a Basic Desktop Computer friendly though....

Re: Raspberry Pi 4 temperature

it would be really nice if there was a Pi4 Lite. sort of cool and usable with HATs and out of the case. the processing power can be lower, as long as it can still run the usual stuff. just without the heat. Isn't that called a 3B(+)? :) at the moment-ish, but you do loose the newer Pi4 capabilities...

If xz is part of tar, then it is natively supported in Windows10 too.
Only at the command line, I don't think it usable in file explorer.

Re: why xz format not used for distribution of raspbian images

It'll be the decompression times that are the important one, how long will we have to wait to get our image.

compression times are only relevant for RPT making the image that one time.

Re: Can i modify the Memory (DRAM) Timing parameter on Rpi2/3/4??

I think the only thing we have is the Shmoo setting. If you understand that you may be able to move the timing and voltage envelope to something tighter.

Or something like that if I have the jist of it correct.

we know that xz format is more efficient compression method. but the raspbian images are distributed in zip compressed image. If xz is used at extreme compression level (level 9), much disk space and bandwidth can be saved. That means Raspbian buster desktop image without recommend softwares, will ...

Re: Uses for Raspberry Pi Zero/Zero W?

Fithly, there are a lot more 32bit only Pi in the wild than there are 64bit capable ones. I'm dubious about that. Everything from the Pi3B and Pi2Bv1.2 onward can run 64-bit. Given the rising sales, year on year, even if one could make a case that 32-bit only Pis are a majority now (which I doubt),...
