Once you get the screen running it's Xwindows that drives it, not Java.

As long as the windowing system works on a full size screen with your Java program there's no reason to assume it won't work on your smaller screen.

The question should be "why does DebIan never upgrade a release except at at version change?"

Buster will have newer versions of lots of packages.

It's the DebIan way and Raspbian mostly follows their dogma.

oh boy, that is a lotta messing.... cant believe the peeps at RPI would make it so difficult to upgrade... The NoobS installer / chooser has always been an issue when upgrading. That's why PINN (the NOOBS fork) added so much in the way of additional functions including the ability to upgrade PINN w...

We have now bumped the master branch of rpi-update to 4.19 kernel for wider testing.

I've justed tested that OpenVPN bug and it's fixed in 4.19.23+.

Nobody knows. Time to sharpen your coding pencil.

Copy the sunwait executable to a location where it will be found by default by Cron.

That's what I did.
sudo cp /home/pi/sunwait /usr/local/bin

Vin connects to pin#1

If you run from a systemd service file add

Kali isn't supported here and there's very few folks running Postgresql.

You should use os.rmdir() os.remove() or os.unlink(). They're the python way.

In each case pass the fully qualified filename or directory name. Don't rely on the shell environment as it won't be the same as running under idle/thonny or in a command window.

The real issue with phpBB3 is the truly awful database design that doesn't scale well and lousy SQL that can't be improved by throwing indexing at it.

This: https://gist.github.com/fm4dd/c66321793 ... c81b0aa845 seems to cover what's possible.

What are you doing? Why are you continuing to beat Jessie to death (She's been dead since August 2017)? What's stopping you upgrading to Stretch (or using a fresh install of Stretch)?

Note: in Autumn 2019 Stretch will be replace by Buster and Jessie will be two versions out of date.

It's the same answer, just with more detail and a useful link to a tutorial !

Because Peter has more desire to do your Googling for you.

hours=[0,0,0,0,0,0,

hours[0] = hours[0]+1

@ fruitoftheloom I think you're right, this module is perfect for production. The bad point is the motherboard size... You are supposed to design and fabricate your own CM3+ carrier board. The big "motherboard" is intended for development only as it includes all the CM3+ interfaces. When you design...

If you feed a GPIO with more than 3.3V or 16mA you will burn it out. If you feed it with back EMF from a motor or solenoid it will die.

You should be switching a MOSFET with the GPIO then switching your load with that MOSFET.

Time to buy a new RPi3B+ as your existing one will soon be 100% dead.

DougieLawson

If you want the kernel headers use rpi-source from https://github.com/notro/rpi-source that will pull the kernel source and headers for your current running kernel.

The best guidance I can offer is DON'T DO THIS. It doesn't make enough difference to boot time.
