JSter #255 - Libraries and more

Summer is the best day of the year.

It's only about a month to this year's Future Frontend conference. I was also able to set up a seminar titled AI meets SDLC for 13.10 at Aalto University. In addition I made my scientific writing book available to the public through the web. I've also been developing a new experimental tool for slide authoring.
