Re: Raspberry Pi SRAM

Quite an interesting troll post if it is though.

But for a Troll post it is odd.
It's not causing tension, its not spamming and it is not an 'odd' question either.
That is assuming there is some translation error and/or poorer English than me.

Re: Windows 10 ARM64 (Dekstop, not IOT)

So you have to either be a member of the Insiders programme or have a valid license key, which, apparently, you can't enter even if you could purchase one. I'm not sure if what was written is how it was meant. My understanding is that if you install it and boot it then it will self-authenticate its...

Re: Windows 10 ARM64 (Dekstop, not IOT)

It's not about making people bit Most schools that I know of use Windows, they already have the licenses, be it individual or Educational and if it is cheap enough then they can roll them out. It does of course have to be usable as a desktop, hence probably not this generation of Pi. A lot of teachi...

Re: Test Rasbian on Zero

Check the connector are fully pushed in, if using 'the official' PiZero case I've found it can push it out a little and sop it displaying.
If the card has been setup for WiFi on the other Pi. Can you see it over the network ?
If you can SSH into it, even better.

Re: Raspberry Pi SRAM

Re: What Raspberry Pi should I get?

The PiZero is $10/15, you'll then need a WiFi dongle or a uUSB hub with Ethernet. That's added cost on top. About £8 for a Ethernet and £12 for Ethernet and hub. The hub being the better option as I assume you'll like to use a mouse and keyboard. Without that, you'll not be able to 'route' But since...

What do you need it for? Text or for the other channels? For me, other than a nice to have as other channels use it to set timers /reminder when adverts are on iirc, which in Kodi/LibreElec may be useful if setup as a PVR. But most just create a front end for either a Broadband streaming channel (on...

The apt full-upgrade is the same as the apt-get dist-upgrade you are doing. apt is just the 'newer' method, iirc it cleans up after itself and give you a nice progress bar, that and four (4) whole character fewer to type ;-) On the forum, the user spl23 https://www.raspberrypi.org/forums/memberlist....

In python there are list comprehensions

So you would (once you know) setup a large list with them and there will be many other ways

For and list of 24 zero's

GPIO on the top edge for me, since its also how all the text and pictures and hats on a Pi are designed. Even on the original Pi, that's always been the way.
