Another year, another calendar

Several years ago I started using remind to generate a printed out calendar each year.  I include things like trash/recycling pickup, when I get paid, important dates for friends and family like birthdays, anniversaries, when clocks change, and fun things like how old our cars are.

I have everything setup to generate the calendar on a PC in the house, but this year I decided I wanted to make a podman container to run remind and generate the PDF.  Why?  Because my current desktop is running bazzite, and while I can install remind using brew, due to other dependencies it didn’t include the rem2pdf helper.  So here is what I did 🙂

My Containerfile:

FROM debian:stable-slim

RUN apt-get update
RUN apt-get install -y remind poppler-utils nvi

Then to build the container:
podman build -t myremind .

And finally to build the PDF:
podman run -v ~/.reminders:/root/.reminders:Z -v ~/Documents:/root/Documents:Z myremind /root/.reminders/update.sh

This uses my local users ~/.reminders directory, mapping it to the /root/.reminders directoring in the container, and doing the same thing with my Documents directory, running the update.sh script that actually does all of the work.

#!/bin/dash

if [ "$#" -eq 0 ];then
    YEAR=$(date +%Y)
else
    YEAR=$1
fi

for i in $(seq 1 12);do
    DATE=$(date --date="${YEAR}-${i}-1" +'%b %Y')
    ODATE=$(date --date="${YEAR}-${i}-1" +'%F')
    remind -pp ~/.reminders ${DATE} | \
# rem2ps -c2 -e -l -sd 15 -se 12 | \
    rem2pdf --small-calendars=2 \
        --fill-page \
        --landscape \
        --entry-font=Helvetica \
        --title-font=Helvetica \
        --small-cal-font=Helvetica \
        --daynum-size=15 \
        --entry-size=9 \
        --margin-top=36 \
        --margin-bottom=0 \
        --margin-left=18 \
        --margin-right=18 \
        > "${ODATE}.pdf"
        # -c2 -e -l
        # ps2pdf - "${ODATE}.pdf"
done

pdfunite ${YEAR}-*.pdf ${YEAR}_full.pdf
cp ${YEAR}_full.pdf ~/Documents/

All of this results in a 12 month calendar that takes a minimum amount of effort to update.  For example, in my house.rem file for my car’s birthday I have a single line:

REM Mar 15 MSG 2013 Fit [since(2014)] Birthday%

Xtenna 40M EFHW, tuned up, ready for POTA.

 

Not long ago I ordered this antenna from the KC8YBC etsy store. Today I finally got it strung up in the backyard between two painter poles so that I could tune it.  I’m planning to use it for some POTA activity near my QTH.  Something I hadn’t noticed until recently was that with the changes to POTA listings, quite a few places within about 10 miles of my house are now possible to activate.   Between this and the x6200, it’s looking like my POTA kit may be getting a little more compact!

The X6200, initial thoughts.

The Xiegu X6200 arrived this morning, a few days earlier than was projected when it shipped.  So far I like it.  I’ve made a couple of contacts to POTA stations this afternoon over my lunch break, both at 5W and 8W, using the built in microphone and using the handheld one.  Except for band conditions being rather bad, I had no issues.

After the work day ended, I grabbed the 9:1 end fed “random” wire antenna, the 10m mast, some feedline, and headed to the back yard.

The internal tuner had no issues with the 9:1 from 40 to 10m.  Even with the display brightness turned down as far as it could go, the screen was readable in direct sunlight.

I have a sneaky suspicion that this is going to turn into my default POTA rig.  We’ll see.  I may even try to activate a park tomorrow night…

You should just leave.

NOTE: I kind of rambled a bit here, sorry about that.
I’ve seen a lot of people over the years, like since I was a kid, express the opinion that if you  don’t like something that is being done where you are, or you don’t agree with the leadership, be it company, local, county, state, or federal politics, that “You should just leave.”
That’s great in theory. That assumes you have the resources to do that, to be able to walk away from that area, that community. Not everyone does. Sometimes it’s money that is the obstacle, sometimes it’s people, friends, family. Sometimes it’s employment. Sometimes it’s all of that and more.
The same can apply to our online communities, the connections that we have with people who may not be physically near us, but who are close to our thoughts and hearts. So please, think of that before you belittle someone for still using an online service that you feel is bad in some way. They most likely know there are problems there as well, and if they are still there, they have a reason.
Also think of that before you say everyone from a particular region is bad, and that the good people should get out, and if they stay, then they must support what is going on there. There have been many times when I have not supported what my local, state, and federal governments have done. I would hate to be held responsible for the acts of others. That doesn’t mean that everyone gets a free pass to just shrug and do nothing. If you don’t support what they are doing, let them know, vote for people that are more closely aligned with your goals. Remember that politics is not taking a ride to exactly where you want to be, it’s like taking a bus. You get on the bus and you take it as close as you can get to where you want to be, sometimes that means you get on another bus from there, or you take a train, or a car, or you walk, to keep moving towards where you want to be.
I know that I have been just as guilty of lumping people into a collective that I think is doing harm and then dismissing them because of that. I’ll probably do it again, because I’m human. But I’m trying not to. I’m trying to not, without evidence, assume that people support the terrible things that others do. But if someone does, then I’m either going to call them on it, or I’m going to decide that it’s not worth the effort, and just move on. That’s going to change day to day, sometimes I just don’t have the emotional/mental bandwidth to be able to do that. And on those days, I’m going to be disappointed in myself, but I’ll just have to deal with it, remember that I am human, and keep trying.

docker-compose.org

This docker-compose.org file lives at /opt/docker-compose.org and is used to generate the /opt/docker-compose.yaml file that spins up all of the services here.

Heading

The :tangle has to be defined here, NOT in the header of the org file.

#+begin_src yaml :tangle "docker-compose.yaml" :noweb yes

If you try to set it in the header, you will get a broken yaml file. ( emacs versions 28 and 29 and the org-mode that comes with them )

Each begin_src has a :noweb-ref NAME definition that is referenced here.

So a simple way to remove a service is to just remove the reference to it from this block.

macvlan.sh

This is a script that allows for docker containers on a macvlan to be able to communicate with each other and the docker host.

brygge is the hostname for this particular system, and enp1s0 is the ethernet interface.

Secrets

Keep secrets in these local files, not great, but better than in the docker-compose.yaml file! These files have JUST the super secret information in them, nothing else.

We reference them later by setting the secrets entry in the needed service. Notice the _FILE added to the end of the environment entry.

My thanks to Adam Jackson for pointing me at this stackoverflow article as a solution to the issues I was having with tangling yaml content in orgmode.

Thinking about workflows and directions

I was thinking about how I want to use this site. I was wondering if I should convert to Hugo, or one of the other static generators, assuming I could keep ActivityPub functionality. But then I remembered that there is an Android app for WordPress. And someone has already built a wp to org converter, so I could pull posts back into emacs for editing and archiving.

That could be a very handy feature as I want to use this site to document ham radio activities like POTA, contests, projects, whatever. That does make me think that I should just point nm9o.com here as well, because I think I can be honest enough with myself that I probably won’t keep two sites active.

So, I guess I am saying that this is going to be an eclectic collection of things that I find interesting. Networking, emacs, Linux, BSD, ham radio, World of Warcraft, Diablo 4, python, wood working, electronics, and a bunch of other topics will all be fair game.

More messing with org2blog

Now that automatic login is working, let’s see if the tracking file works.

I opted to just set it, instead of trying to wrap it into the config option that auth took. 

(setq org2blog/wp-track-posts (list "org2blog.org" "technomage.net"))

And while messing with this post I decided to go super old school and grab the 2012 wordpress theme.

Of course it wasn’t that easy.

Of course it wasn’t that easy. A little more testing on my part and using webfinger would have probably helped. Oh well. 

location = /.well-known/webfinger {
    try_files $uri $uri/ /index.php?$args;
}

location = /.well-known/nodeinfo {
    try_files $uri $uri/ /index.php?$args;
}

I had to add a little glue to my nginx configuration, otherwise queries were not routed to the right place.

Of course now, this is another live test after I have successfully followed my blog from main mastodon account, so… fingers crossed!

Edit: And now that I have added src code plugin, let’s see if this looks better.

Plugging wordpress into the fediverse

One of the things that has been frustrating sometimes is that I want to make a longer post on , but run into the character limits. I appreciate the character limits, I really do, but there are times when I want to be a little more verbose.

I’ve looked at possibly running something like writefreely, or one of the other first platforms. But then I remembered that wordpress had a plugin. And the most recent iteration of my website is running on wordpress, although, up until today it was running on a host in my house and a static export of that was being uploaded to the server.

One of the other things that I wanted to have was the ability to work on blog posts in an efficient way using . So now I have org2blog plugged into my emacs configuration.

As this is my first post using this conglomeration of tools and tech, we’ll see if it works, or if I have a succession of “did it work this time?” posts…
