+ <div class="date">11th January 2025</div>
+ <div class="body"><p><a href="https://linuxcnc.org/">The LinuxCNC project</a> 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.</p>
+
+<p>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
+<a href="https://en.wikipedia.org/wiki/Unconference">unconference</a>,
+where the participants create the program upon arrival.</p>
+
+<p>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.</p>
+
+<p>Please let us know if you would like to join. We track the list of
+participants on <a href=https://pad.efn.no/p/linuxcnc-2025-norway">a
+simple pad</a>, please add yourself there if you are interested in joining.</p>
+
+<p><a href="https://www.nuugfoundation.no/">The NUUG Foundation</a> 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.</p>
+
+<p>As usual we hope to find sponsors to pay for food, lodging and travel.</p>

- <div class="date"> 3rd March 2024</div>
- <div class="body"><p>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
-<a href="https://wiki.debian.org/LinuxRaidForAdmins">Debian wiki page
-"Linux and Hardware RAID: an administrator's summary"</a> 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.</p>
-
-<p>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
-<a href="https://bugs.debian.org/1065322">request for packaging of the
-megactl package</a>, and tried to track down a usable version.
-<a href="https://sourceforge.net/p/megactl/">The original project
-site</a> 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
-<a href="https://github.com/hmage/megactl">more recent fork on
-github</a> from user hmage, but it is unclear to me if this is still
-being maintained. It has not seen much improvements since 2016. A
-<a href="https://github.com/namiltd/megactl">more up to date
-edition</a> 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
-<a href="https://github.com/namiltd/megactl/pull/1">my first pull
-request</A> 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.</p>
-
-<p>In any case, I created
-<a href="https://salsa.debian.org/debian/megactl">a draft package</a>
-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.</p>
-
-<p>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. :).</p>

-<p>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?</p>
-
-<p>In the packaging process I provided some patches upstream to
-improve installation and ensure
-<ahref="https://github.com/namiltd/megactl/pull/2">a Appstream
-metainfo file is provided</a> to list all supported HW, to allow
-<a href="https://tracker.debian.org/isenkram">isenkram</a> to propose
-the package on all servers with a relevant PCI card.</p>
