Sometimes, regardless of the pins, it's simply impossible to put pins into the ground no matter the technology. In such a situations, boulders may be your friend:
Raising a tent between Baugevatnet and Sijdasjávrre, near Narvik, Norway, ~68.1°N, 1 October 2012. The ground was frozen solid and it was completely impossible to drive a peg into the ground.
My friend taught me a way to raise a tent under such conditions. It works best with a self erecting tent, which mine isn't, but we managed still. For each rope, find a rock as large as possible where it's possible to tie the rope around. If this rock is still small (depending on the tent design, it very well may be), build a cairn around this rock as to put weight on this connecting point. In the photograph above, we didn't use a single peg, but the tent was very stable.
Although I didn't bring a thermometer, I think it was close to -10°C during the night, and it took a long time for temperatures to rise during the day. Incidentally, it was the last night camping in the wild before winter would put an end to the snow-free season.
It was worth it!
