<h2 id="audiobooks"><time>2023-11-13</time> - audiobooks</h2>
<p>okay so tomasino reminded me today that i used to love listening to
audiobooks.</p>
<p><a href="https://labs.tomasino.org/audiobooks/"
class="uri">https://labs.tomasino.org/audiobooks/</a></p>
<p>but i haven’t done it as fanatically as i used to in a long time. for
a while, i didn’t have a commute. and now i do, but i often carpool. but
sometimes i have a solo, quiet commute. ideal for some audiobooks!</p>
<p>further complications: i am unable to download and archive audiobooks
from overdrive the same way i used to be able to. because they barely
support their desktop apps anymore, and instead push really hard for
everybody to use their streaming apps.</p>
<p>but i learned that if i spoof my user-agent</p>
<p><a
href="https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher/"
class="uri">https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher/</a></p>
<p>then i can get a ‘Have overdrive for mac/windows?’ link upon checkout
that will enable me to download the odm file. which i can then use to
download the mp3s thanks to this special little script.</p>
<p><a
href="https://github.com/jamestomasino/dotfiles-minimal/blob/master/bin/overdrive"
class="uri">https://github.com/jamestomasino/dotfiles-minimal/blob/master/bin/overdrive</a></p>
<p>so that’s great! while i was troubleshooting all of this, i
downloaded a book to my linux laptop, because the download link is
already readily available there, and then transferred it over to the
pi.</p>
<p>so now i guess i’m going to start collecting and archiving audiobooks
on the pi too! i might look into jellyfin in earnest so i can serve them
and download them over my home network.</p>
<p>i might also have to start really considering a vpn so i can access
my files away from the house.</p>
<h2 id="add-email-to-calibre-web"><time>2023-11-07</time> - add email to
calibre-web</h2>
<p>just a quick note to look into configuring email for calibre-web so i
can send books direct to my kindle</p>
<p>whoa this fork looks really great compared to what i have</p>
<p><a href="https://github.com/janeczku/calibre-web"
class="uri">https://github.com/janeczku/calibre-web</a></p>
<p>the ui looks good and it has single click send to e-mail and also
“Magic Link” login for easy access on eReaders.. that’s great.</p>
<p>what is that i’m running?</p>
<p>just the base <code>calibre-server</code> that comes with the calibre
package in apt.</p>
<p>okay new goal: install and run <code>calibre-web</code>, and stop
using <code>calibre-server</code>?</p>
<h2 id="abduco-dvtm-tmux-replacement"><time>2023-10-28</time> - abduco +
dvtm = tmux replacement?</h2>
<p>i can’t remember how i fell down this rabbit hole.. i think it’s
because elly had been talking about dtach over on #tildetown, which is a
utility that just provides the attach/detach functionality of tmux.</p>
<p>so anyway i started using abduco + dvtm on my pi just to test it out
and see what it was like and i quite like it! dvtm especially is kind of
nice as a tiling window manager for the terminal.</p>
<p>abduco isn’t in the package repository at work, but i started using
dtach + dvtm this week. we’ll see if i stick with it. pretty nice so
far!</p>

<h2 id="jellyfin"><time>2023-10-11</time> - jellyfin</h2>
<p>just a quick note to remind myself to check out jellyfin</p>
<p><a href="https://jellyfin.org/"
class="uri">https://jellyfin.org/</a></p>
<p>a media server alternative to plex that is supposed to be much
lighter and more simple than plex.</p>
<h2 id="dedrm"><time>2023-09-29</time> - DeDRM</h2>
<p>shelled into the pi and curled the latest DeDRM tools release</p>
<p><a href="https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.3"
class="uri">https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.3</a></p>
<p>but i kept getting an empty file for some reason?</p>
<p>no matter, downloaded it to my laptop and <code>scp</code>d it</p>
<p>unzipped it on the pi and</p>
<pre><code>calibre-customize --add DeDRM.zip</code></pre>
<p>it wasn’t working at that point because i didn’t have any keys
defined in the <code>dedrm.json</code> so I <code>scp</code>d my config
json from my laptop to <code>.config/calibre/plugins/DeDRM</code>. at
this point, i’m still unable to open the book after adding it via the
web ui. but when i
<code>calibredb --add book.epub --with-library=books --duplicates</code>
on the pi terminal, it adds it. (<code>--duplicates</code> is necessary
only in this test instance because—oops!—turns out i already have this
book in my library, but i am determined to use this opportunity to set
up DeDRM. i will delete the duplicate later.) I can’t verify in the web
ui though because it’s not showing the duplicate. must have merged it
with the old one.</p>
<p>oh well. i’ll try it again next time i get a book from the library.
shortest wait: currently 6 weeks.</p>
<p>actually no, let’s just go checkout an Available Now book. Song of
Achilles. I liked Circe. Let’s get this one.</p>
<ul>
<li><p>confirmed: can add the book via web ui, but not open or read it
because of drm</p></li>
<li><p>confirmed: can scp the book to the pi,
<code>calibre add book.epub --with-library=books</code> and get an
<code>Added book ids: &lt;id&gt;</code> message</p></li>
<li><p>confirmed: new book does NOT show up in web ui after killing and
restarting the daemon</p></li>
<li><p>confirmed: the book IS there:</p>
<pre><code> ```
$ calibredb list --search=&#39;id:3&#39; --with-library=books
id title authors
3 The Song of Achilles Madeline Miller
$ #wtf
```</code></pre></li>
</ul>
<p>what the hell. does <code>calibre-server</code> has a db cache or
something? i don’t see anything</p>
<p><a
href="https://manual.calibre-ebook.com/generated/en/calibre-server.html"
class="uri">https://manual.calibre-ebook.com/generated/en/calibre-server.html</a></p>
<p>i give up for now</p>
<p>~</p>
<p>to kill the process:</p>
<pre><code>ps aux | grep calibre</code></pre>
<p>and then kill the id</p>
<p>removing the dulplicate:</p>
<pre><code>calibredb search &#39;title:&quot;world we make&quot;&#39; --with-library=books
&gt; 1,2
calibredb list --search &#39;id:2&#39; --with-library=books
&gt; (book info)
calibredb list --search &#39;id:1&#39; --with-library=books
&gt; (book info)
calibredb remove 2</code></pre>
<p>tags: #calibre #drm</p>
<h2 id="reboot"><time>2023-09-29</time> - reboot</h2>
<p>been uploading photos and books, and editing metadata for my
rpgs.</p>
<p>pi became unresponsive last night / this morning to web and ssh so
rebooted this morning and restarted web services. everything seems to be
fine now.</p>
<p>found these resources recently and consider them next steps on my
todo list:</p>
<ul>
<li><p>Add deDRM tools for CLI so I can upload library books. I can
pretty much delete local calibre after this. <a
href="https://github.com/noDRM/DeDRM_tools/blob/master/CALIBRE_CLI_INSTRUCTIONS.md"
class="uri">https://github.com/noDRM/DeDRM_tools/blob/master/CALIBRE_CLI_INSTRUCTIONS.md</a></p></li>
<li><p>Be your own CA Authority! which initially sounds to me like not
that good of an idea, but then I can use <code>https</code> for my local
webservices. <a
href="https://jamielinux.com/docs/openssl-certificate-authority/"
class="uri">https://jamielinux.com/docs/openssl-certificate-authority/</a></p></li>
<li><p>still want to install a reverse proxy (lapis + openresty?) so i
can hit canonical urls instead of typing in address + port number. this
would make it easier to share URLs with household members. NOTE: do i
want a local DNS server??</p></li>
</ul>
<p>Incidentally, mDNS seemed to just magically start working on its self
at some point. I can hit my pi’s url on macbook and on my phone now.
weeeeeird</p>
<p>tags: #reboot #mdns</p>
<h2 id="rpg-library"><time>2023-09-13</time> - rpg library</h2>
<p>tried searching for an rpg that i know is in my collection and
couldn’t find it by title or by author. this is going to be really
painful until i update the metadata on everything. i’ve done about 60 so
far. out of 1.4k. big yikes!</p>
<p>tags: #calibre #rpg #metadata</p>
<h2 id="mdns"><time>2023-09-12</time> - mDNS</h2>
<p>still can’t hit any multi DNS urls on any of my devices.</p>
<p>not a solution but a workaround (for desktop only): added a line to
<code>/etc/hosts</code> on my MBP:</p>
<pre><code>192.168.0.83 pi.local</code></pre>
<p>and now i can hit e.g. calibre with <a href="http://pi.local:8080"
class="uri">http://pi.local:8080</a></p>
<p>maybe i can configure something on my actual router?</p>
<p>tags: #mdns</p>
<h2 id="miniflux"><time>2023-09-11</time> - miniflux</h2>
<p>rss reader!</p>
<p>one thing i would like to be able to do is to read my rss feeds on my
computer and on my phone and on my tablet, and have my un/read status
sync between decives.</p>
<p>which i guess means hosting a feed reader!</p>
<p>i glanced at <code>awesome-selfhosted</code> and then asked some of
my friends in the basement because i know that they have already
undertaken great adventures in rss, trailblazers that they are.</p>
<p>and they recommended miniflux.</p>
<p>written in go, and it uses postgres. luckily they have a docker image
so i don’t have to install either. the docker-compose file on their
installation instructions is a little out of date, but you can find a
more correct ‘basic.yml’ on github at <code>miniflux/v2</code></p>
<p>after a few tweaks, it is installed and running!</p>
<p>the ui is super minimal. i’m sure i’ll grow to like it, but at the
moment i am missing the classic three-pane “feeds / entries / content”
view.</p>
<p>Up next:</p>
<ul>
<li>gemini/gopher server? just for fun</li>
<li>nginx reverse proxy: i have three services running on three ports
now. i want a proxy for more easiy routing between these. i choose nginx
because lua, so i can fennel</li>
</ul>
<p>tags: #rss #feeds #miniflux</p>
<h2 id="calibre"><time>2023-09-08</time> - calibre</h2>
<p>had to add the upstream debian bullseye repo to install
<code>calibre-server</code>. (and then remove it.) got the web server up
and running pretty easy.</p>
<p>fussed around for a while trying to make a second calibre library out
of my rpg collection. here’s what ended up working: create a new dir and
then
<code>calibredb add path/to/file.pdf --library-path new/library/location</code>.
adding a single file this way created the necessary database file. then
i was able to
<code>find rpgsbak -type f -name '*.pdf' -exec -I {} calibredb add {} --library-path new/library/loction</code>.
(or something like that; wrote the command just now from memory.) and
pull all my pdfs in!</p>
<p>so now i have 1.4k pdfs in a new ‘rpgs’ library alongside my ‘books’
library.</p>
<p>on the whole, hobby ttrpg creators can stand to get a LOT better at
exporting metadata with their pdfs. now i have a whole lot of manual
updating to do. but i can read books and pdfs now from my calibre
library on any device on the network.</p>
<p>also adding new items via the web ui is pretty easy!</p>
<p>TODO: disable converting to epub on ‘read’ for rpg library.
‘download’ to read still works great for reading in the meantime.</p>
<p>tags: #calibre</p>
<h2 id="photoprism"><time>2023-09-03</time> - photoprism</h2>
<p>browsed the photo hosting options on <code>awesome-selfhosted</code>
on github and decided on photoprism</p>
<p>it has a docker image and i was able to get it working no problem,
with no modifications. quick and easy. this is the future containers
promised us.</p>
<p>the ui is slow. i have the number of workers cranked down to 1. might
bump it to 2.</p>
<p>i had been rsyncing photos to the pi and then reindexing the
collection. but i’m finding it quicker to do a bulk upload using the web
ui. it’s working rather reliably. it still has to reindex on upload, but
i no longer have to reindex the entire collection.</p>
<p>tags: #photos #photoprism</p>
<h2 id="git"><time>2023-08-30</time> - git</h2>
<p>Add a “git” user. Create a home dir for it. Do
<code>git init --bare repo.git</code>.</p>
<p>Copy my ssh key over and add an entry to
<code>.ssh/config</code>:</p>
<pre><code> 21 │ Host git
22 │ Hostname 192.168.0.83
23 │ User git
24 │ IdentityFile ~/.ssh/id_rsa</code></pre>
<p>Now I can <code>git remote add pi git:repo.git</code> in a local repo
and push away!</p>
<p>tags: #git</p>
<h2 id="hello-world"><time>2023-08-28</time> - Hello World</h2>
<p>Okay let’s get this party started!</p>
<p>I have a raspberry pi model 3b that has been gathering dust in a
drawer for a couple years now.</p>
<p>I decided I wanted to dust it off and use it to backup some photos
and some files.</p>
<p>I bought a 4TB external hard drive and a 128gb microSD card and
hooked it all up.</p>
<p>I downloaded the NOOBS installer from raspberrypi.com/software and
installed it on the SD card, which I was able to do because I have a ton
of dongles thanks to the fact that my MacbookPro has no peripherals. I
popped the card in to the pi, connected my usb keyboard and hdmi monitor
and booted it up, and went through the setup.</p>
<p>Then, after testing that I can ssh into the pi, I unplugged my
keyboard and monitor and never plugged them back in again.</p>
<p>Plugged in my hard drive and formatted it with an ext3
filesystem.</p>
<p>Created a backup user. (Not a spare user in case of emergencies, but
a user specifically for creating backups.)</p>
<p>Copied my ssh keys over:</p>
<pre><code>ssh-copy-id -i ~/.ssh/id_rsa pi.local</code></pre>
<p>Mounted the drive, added it to <code>/etc/fstab</code> so it will
auto-mount, and added a slight delay to the boot command so that there
is time for the drive to mount before the system boots. As suggested
here:</p>
<p><a
href="https://howtoforge.com/tutorial/raspberry-pi-as-backup-server-for-linux-and-windows/"
class="uri">https://howtoforge.com/tutorial/raspberry-pi-as-backup-server-for-linux-and-windows/</a></p>
<p>Copied over my first photo export and my calibre library with an
<code>rsync -zaP</code>.</p>
<p>Messed around with mDNS and avahi-daemon because I can’t hit <a
href="http://pi.local" class="uri">http://pi.local</a> in the browser.
Still haven’t figured this out.</p>
