I have written a guest blog post for the ISC'12 website - "Are you an ISC veteran?". The article is intended to raise a few serious observations amongst the fun.
I also wrote an earlier guest blog post for the ISC'12 website - "Is co-design for exascale computing a false hope?"
I've added these two links to my page on this site "Interviews, Quotes, Articles" (which lists my various articles, interviews, etc. in other locations around the internet).
