+<h1>Description</h1>
+<p>In this talk we will present the current status of PyPy, with a
+particular focus on what happened in the last two years, since the last
+EuroPython PyPy talk.  We will give an overview of the current speed and
+the on-going development efforts, including but not limited to:</p>
+<ul class="simple">
+<li>the status of the Just-in-Time Compiler (JIT) and PyPy performance in
+general;</li>
+<li>the improvements on the Garbage Collector (GC);</li>
+<li>the status of the NumPy and Python 3 compatibility subprojects;</li>
+<li>CFFI, which aims to be a general C interface mechanism for both
+CPython and PyPy;</li>
+<li>a quick overview of the STM (Software Transactional Memory) research
+project, which aims to solve the GIL problem.</li>
+</ul>
+<p>This is the &quot;general PyPy status talk&quot; that we give every year at
+EuroPython (except last year; hence the &quot;no no, PyPy is not dead&quot; 
part
+of the title of this talk).</p>

+<h1>Abstract</h1>
+<p>PyPy, the Python implementation written in Python, experimentally
+supports Transactional Memory (TM). The strength of TM is to enable a
+novel use of multithreading, inheritently safe, and not limited to
+special use cases like other approaches. This talk will focus on how it
+works under the hood.</p>
+</div>
+<div class="section" id="description">
+<h1>Description</h1>
+<p>PyPy is a fast alternative Python implementation.  Software
+Transactional Memory (STM) is a current academic research topic.  Put
+the two together --brew for a couple of years-- and we get a version of
+PyPy that runs on multiple cores, without the infamous Global
+Interpreter Lock (GIL).</p>
+<p>The current research is based on a recent new insight that promises to
+give really good performance.  The speed of STM is generally measured by
+two factors: the ability to scale with the number of CPUs, and the
+amount of overhead when compared with other approaches in a single CPU
+(in this case, with the regular PyPy with the GIL).  Scaling is not
+really a problem here, but single-CPU performance is --or used to be.
+This new approach gives a single-threaded overhead that should be very
+low, maybe 20%, which would definitely be news for STM systems.  Right
+now (February 2014) we are still implementing it, so we cannot give
+final numbers yet, but early results on a small interpreter for a custom
+language are around 15%.  This looks like a deal-changer for STM.</p>
+<p>In the talk, I will describe our progress, hopefully along with real
+numbers and demos.  I will then dive under the hood of PyPy to give an
+idea about how it works.  I will conclude with a picture of how the
+future of multi-threaded programming might looks like, for high-level
+languages like Python.  I will also mention CPython: how hard (or not)
+it would be to change the CPython source code to use the same approach.</p>
