+    <content type="html">&lt;p&gt;It has been 9 months since I last wrote about open (maths) research. Since then two things happened which prompted me to write an update.&lt;/p&gt;
 &lt;p&gt;As always I discuss open research only in mathematics, not because I think it should not be applied to other disciplines, but simply because I do not have experience nor sufficient interests in non-mathematical subjects.&lt;/p&gt;
 &lt;p&gt;First, I read about Richard Stallman the founder of the free software movement, in &lt;a href="http://shop.oreilly.com/product/9780596002879.do"&gt;his biography by Sam Williams&lt;/a&gt; and his own collection of essays &lt;a href="https://shop.fsf.org/books-docs/free-software-free-society-selected-essays-richard-m-stallman-3rd-edition"&gt;&lt;em&gt;Free software, free society&lt;/em&gt;&lt;/a&gt;, from which I learned a bit more about the context and philosophy of free software and open source software. For anyone interested in open research, I highly recommend having a look at these two books. I am also reading Levy’s &lt;a href="http://www.stevenlevy.com/index.php/books/hackers"&gt;Hackers&lt;/a&gt;, which documented the development of the hacker culture predating Stallman. I can see the connection of ideas from the hacker ethic to free software to the open source philosophy. My guess is that the software world is fortunate to have pioneers who advocated for freedom and openness from the beginning, whereas for academia which has a much longer history, credit protection has always been a bigger concern.&lt;/p&gt;
 &lt;p&gt;Also a month ago I attended a workshop called &lt;a href="https://www.perimeterinstitute.ca/conferences/open-research-rethinking-scientific-collaboration"&gt;Open research: rethinking scientific collaboration&lt;/a&gt;. That was the first time I met a group of people (mostly physicists) who also want open research to happen, and we had some stimulating discussions.&lt;/p&gt;
