+      <p>BSDCan, a conference for people working on and with
+	4.4BSD-based operating systems and related projects, was held
+	in Ottawa, Ontario on June 12 and 13.  A two-day &os;
+	developer summit event preceded it on June 10 and 11.</p>
+
+      <p>This was the largest BSDCan ever, with over 280 attendees, up
+	by more than 40 people over the 2014 event.  There were a
+	record number of speakers and talks.  An additional room and
+	"track" was added to provide even more choices for concurrent
+	talks on both days of the conference.  Social media response
+	to the whole conference has been very positive.</p>
+
+      <p>The keynote talk by Stephen Bourne was very popular.  So
+	popular, in fact, that the main conference room could not hold
+	all the attendees.  An overflow room with live video was set
+	up to hold the extra people.  The
+	<a href="https://www.youtube.com/watch?v=2kEJoWfobpA">video</a>
+	of the presentation has had over 6300 views in the first
+	twelve days.</p>
+
+      <p>Andrew Tanenbaum's talk on
+	<a href="https://www.youtube.com/watch?v=0pebP891V0c">reimplementing NetBSD using a MicroKernel</a>
+	was so well-attended it was standing room only.</p>
+
+      <p>There were many other excellent talks, and we recommend
+	browsing through the playlist in the links above.</p>
+
+      <p>Activity was not limited to the talks.  Each night, the
+	"Hacker Lounge" was used by developers to cooperate and
+	interact on projects.  Embedded projects were popular this
+	year, as FreeBSD was installed directly on wireless
+	routers.</p>
+
+      <p>The very successful and well-attended closing event, held
+	at the Lowerton Brewery, provided an elegant closure to the
+	whole conference.</p>
+
+      <p>We would like to thank everyone who made BSDCan 2015 such a
+	success, and look forward to next year!</p>

+      <p>PCI Express (PCIe) hot-plug is used on both laptops and
+	servers to allow peripheral devices to be added or removed
+	while the system is running.  Laptops commonly include a
+	hot-pluggable PCIe as either an ExpressCard slot or
+	Thunderbolt interface.  ExpressCard has built in USB support
+	that is already supported by &os;, but ExpressCard PCIe
+	devices like Gigabit Ethernet adapters and eSATA cards are
+	only supported when they are present at boot, and removal may
+	cause &os; to crash.</p>
+
+      <p>The goal of this project is to allow these devices to be
+	inserted and removed while &os; is running.  The work will
+	provide the basic infrastructure to support adding and
+	removing devices, though it is expected that additional work
+	will be needed to update individual drivers to support
+	hot-plug.</p>
+
+      <p>Current testing is focused on getting a simple UART device
+	functional.  Basic hot swap is functional.</p>
+
+      <p>A set of the patches is now available on github.com.</p>
