<p>Please let me know if you'd like to talk about anything
Lisp-related for the future meetings - the slots for the next one
are open, and I'll gladly host anything from a full-sized talk to
a series of lightning talks, previews, and teasers.<br>
</p>
<p>Thanks, and Lisp you all later!<br>

<p>Good morning, everyone! I am pleased to announce the third
Online Lisp Meeting.<br>
</p>
<p>There are two speakers for the third Online Lisp Meeting: Mark
Evenson, the current maintainer of Armed Bear Common Lisp, and
Robert Strandh, the initiator of SICL, the upcoming modular
implementation of Common Lisp.<br>
</p>
<p>Mark Evenson will talk about "Reflections on the Future History
of Arming Bears".<br>
</p>
<blockquote type="cite">
<p>With the recent releases of Armed Bear Common Lisp over the
past six months, the future of extending the implementation
has come into sharper focus. The majority of this work has
occurred within the head of one individual with little chance
for public review and reflection, we believe that an
externalized exposition of the reasoning behind these efforts
would be of interest to those interested in the future history
of Common Lisp implementations.</p>
<p>Most notably, with abcl-1.6.0 we extended the set of
underlying Java Virtual Machines (JVM) that the implementation
runs on to include openjdk11 and openjdk14 while maintaining
compatibilty with openjdk6. And with the internal overhaul or
arrays specialized on unsigned bytes in abcl-1.7.0, we made it
possible to share such byte vectors with memory allocated
outside of the hosting JVM via system interfaces such as
malloc(). We first present the goals and challenges in
affecting these changes within the ABCL codebase. Then, we
use this initial exposition to serve as a springboard to
discuss outstanding needed changes in the ABCL 1 branch, and
to outline some of the features intended to be present in ABCL
2, due to be released in the Fall of 2020.</p>

<p>Robert Strandh will talk about First-Class Global Environments
in Common Lisp.</p>
<p> </p>
<blockquote type="cite">At the European Lisp Symposium in 2015, we
presented a paper entitled "First-class Global Environments in
Common Lisp". There are several possible use cases for such
environments. In this presentation, we investigate the use of
such environments at run time for so-called "sandboxing", i.e.,
to allow only a pre-selected set of functionalities to be
visible to application code. In particular, we demonstrate the
main idea that allows such environments to be used with no
performance loss in almost all cases.</blockquote>
As before, the talk will be pre-recorded and played back on
Twitch, with the ability to comment on the Twitch chat during
playback. Afterwards, we will have an online drink and chat on
Jitsi. The videos will then make it onto YouTube.<br>
