<h1 class="title">Twelve Weeks at the Recurse Center</h1>
<p>
It's been four weeks since I finished my batch at the Recurse Center and I'm
finally getting around to publishing what I did in weeks seven through twelve.
I wrote about the things I did in my first six weeks here
<a href="http://ryanriddle.github.io/six-weeks.html">http://ryanriddle.github.io/six-weeks.html</a>.
</p>

<p>
In weeks seven through twelve
</p>

<ul class="org-ul">
<li>I added atomic transactions to my database using a rollback journal
</li>
<li>I added isolated transactions to my database using locks
</li>
<li>I learned Ruby does not have read-write locks
</li>
<li>I tried and failed to implement read-write locks in Ruby
</li>
<li>I learned how to use the system call fcntl to get locks on files and I gave a presentation on it
</li>
<li>I rewrote the isolated transaction code to use MVCC
</li>
<li>I learned about isolation levels
</li>
<li>I learned when and how to use condition variables and I used them to implement serializable, isolated transactions in my database
</li>
<li>I learned about concurrency models that do not rely on locking like software transactional memory
</li>
<li>I contributed to <a href="http://pump.io">http://pump.io</a>
</li>
<li>I hacked around with <a href="http://bittorrent.org/beps/bep_0044.html">BEP44</a> for storing arbitrary data on the BitTorrent distributed hash table
</li>
<li>I played with a Clojure library called Overtone for making music
</li>
<li>I used React Native to create an Android app to help me catch the bus
</li>
</ul>

<p>
There are also things I never got around to doing.  When I started my batch I
wanted to work on crypto, machine learning, and gpu programming. Looking back
the things I wanted to do but didn't don't seem important.  What's important
to me is I learned a lot, I had fun, and I met great people.  And the things
I still want to do, like GPU programming, I can still do.  I just have to make
time.  Never graduate!
