+               <description>&lt;p&gt;&lt;a href=&quot;https://linuxcnc.org/&quot;&gt;The LinuxCNC project&lt;/a&gt; is
+trotting along.  And I believe this great software system for
+numerical control of machines such as milling machines, lathes, plasma
+cutters, routers, cutting machines, robots and hexapods, would do even
+better with more in-person developer gatherings, so we plan to
+organise such gathering this summer too.&lt;/p&gt;
+
+&lt;p&gt;This year we would like to invite to a small LinuxCNC and free
+software fabrication workshop/gathering in Norway this summer for the
+weekend starting July 4th 2024.  New this year is the slightly larger
+scope, and we invite people also outside the LinuxCNC community to
+join.  As earlier, we suggest to organize it as an
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Unconference&quot;&gt;unconference&lt;/a&gt;,
+where the participants create the program upon arrival.&lt;/p&gt;
+
+&lt;p&gt;The location is a metal workshop 15 minutes drive away from to the
+Gardermoen airport (OSL), where there is a lot of space and a hotel only
+5 minutes away by car. We plan to fire up the barbeque in the evenings.&lt;/p&gt;
+
+&lt;p&gt;Please let us know if you would like to join.  We track the list of
+participants on &lt;a href=https://pad.efn.no/p/linuxcnc-2025-norway&quot;&gt;a
+simple pad&lt;/a&gt;, please add yourself there if you are interested in joining.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;https://www.nuugfoundation.no/&quot;&gt;The NUUG Foundation&lt;/a&gt; has on
+our request offered to handle any money involved with this gathering,
+in other words holding any sponsor funds and paying any bills.
+NUUG Foundation is a spinnoff from the NUUG member organisation here
+in Norway with long ties to the free software and open standards
+communities.&lt;/p&gt;
+
+&lt;p&gt;As usual we hope to find sponsors to pay for food, lodging and travel.&lt;/p&gt;

-               <description>&lt;p&gt;The last few days I have revisited RAID setup using the LSI
-Megaraid controller.  These are a family of controllers called PERC by
-Dell, and is present in several old PowerEdge servers, and I recently
-got my hands on one of these.  I had forgotten how to handle this RAID
-controller in Debian, so I had to take a peek in the
-&lt;a href=&quot;https://wiki.debian.org/LinuxRaidForAdmins&quot;&gt;Debian wiki page
-&quot;Linux and Hardware RAID: an administrator&#39;s summary&quot;&lt;/a&gt; to remember
-what kind of software is available to configure and monitor the disks
-and controller.  I prefer Free Software alternatives to proprietary
-tools, as the later tend to fall into disarray once the manufacturer
-loose interest, and often do not work with newer Linux Distributions.
-Sadly there is no free software tool to configure the RAID setup, only
-to monitor it. RAID can provide improved reliability and resilience in
-a storage solution, but only if it is being regularly checked and any
-broken disks are being replaced in time.  I thus want to ensure some
-automatic monitoring is available.&lt;/p&gt;
-
-&lt;p&gt;In the discovery process, I came across a old free software tool to
-monitor PERC2, PERC3, PERC4 and PERC5 controllers, which to my
-surprise is not present in debian.  To help change that I created a
-&lt;a href=&quot;https://bugs.debian.org/1065322&quot;&gt;request for packaging of the
-megactl package&lt;/a&gt;, and tried to track down a usable version.
-&lt;a href=&quot;https://sourceforge.net/p/megactl/&quot;&gt;The original project
-site&lt;/a&gt; is on Sourceforge, but as far as I can tell that project has
-been dead for more than 15 years.  I managed to find a
-&lt;a href=&quot;https://github.com/hmage/megactl&quot;&gt;more recent fork on
-github&lt;/a&gt; from user hmage, but it is unclear to me if this is still
-being maintained.  It has not seen much improvements since 2016.  A
-&lt;a href=&quot;https://github.com/namiltd/megactl&quot;&gt;more up to date
-edition&lt;/a&gt; is a git fork from the original github fork by user
-namiltd, and this newer fork seem a lot more promising.  The owner of
-this github repository has replied to change proposals within hours,
-and had already added some improvements and support for more hardware.
-Sadly he is reluctant to commit to maintaining the tool and stated in
-&lt;a href=&quot;https://github.com/namiltd/megactl/pull/1&quot;&gt;my first pull
-request&lt;/A&gt; that he think a new release should be made based on the
-git repository owned by hmage.  I perfectly understand this
-reluctance, as I feel the same about maintaining yet another package
-in Debian when I barely have time to take care of the ones I already
-maintain, but do not really have high hopes that hmage will have time
-to spend on it and hope namiltd will change his mind.&lt;/p&gt;
-
-&lt;p&gt;In any case, I created
-&lt;a href=&quot;https://salsa.debian.org/debian/megactl&quot;&gt;a draft package&lt;/a&gt;
-based on the namiltd edition and put it under the debian group on
-salsa.debian.org.  If you own a Dell PowerEdge server with one of the
-PERC controllers, or any other RAID controller using the megaraid or
-megaraid_sas Linux kernel modules, you might want to check it out.  If
-enough people are interested, perhaps the package will make it into
-the Debian archive.&lt;/p&gt;
-
-&lt;p&gt;There are two tools provided, megactl for the megaraid Linux kernel
-module, and megasasctl for the megaraid_sas Linux kernel module. The
-simple output from the command on one of my machines look like this
-(yes, I know some of the disks have problems. :).&lt;/p&gt;

-&lt;p&gt;In addition to displaying a simple status report, it can also test
-individual drives and print the various event logs.  Perhaps you too
-find it useful?&lt;/p&gt;
-
-&lt;p&gt;In the packaging process I provided some patches upstream to
-improve installation and ensure
-&lt;ahref=&quot;https://github.com/namiltd/megactl/pull/2&quot;&gt;a Appstream
-metainfo file is provided&lt;/a&gt; to list all supported HW, to allow
-&lt;a href=&quot;https://tracker.debian.org/isenkram&quot;&gt;isenkram&lt;/a&gt; to propose
-the package on all servers with a relevant PCI card.&lt;/p&gt;
-

-activities, please send Bitcoin donations to my address
