It’s been a while [en]

My last post here has been over 4 years ago. I’ve really neglected this blog. Let’s see, if I can change that… Part of the problem was the rotten technology underneath. Even apart from WordPress.

The xkcd guy nails it again [en]

This time, at the intersection of computer science (my occupation) and biology (my hobby): According to Randall, we’re still 2 years ahead of the hype cycle. Anyone willing to join me in switching to CRISPR/Cas9 by then? Update: Thinking about it, told you so.
