Hello,
I just wired up the second tutorial and got it to work (accidently) by removing the reset switch and then it works when I short pin 1 to 5V!
The schematic clearly shows that the reset should short to ground, so the unexpected result is confusing to me! Does anyone have any idea why my circuit could behave like this?
Any help would be appreciated.
Thanks!

I have a basic understanding of analog circuit theory (a degree in mechanical engineering). Have no background in digital circuits, just an interest…
I use linux (Ubuntu) and had no problems with avr-gcc or avddude. Here is my terminal output (when loading the code onto the chip):
