Hi!
My name is Marcel Kapfer and I'm a creative being.
#+end_export
** Coding
I learned Java as my first programming language back in 2014 and started a first project, the [[https://gitlab.com/mmk2410/writtenmorse-specs/-/wikis/home][writtenMorse]] project.
It provided tools to convert writtenMorse code to Latin letters and the other way around. (Btw.: The writtenMorse code itself is an “invention” of mine for better writing Morse code by using other symbols than dots and dashes).
Later in 2014 I started to learn coding for Android, since I wanted to develop a writtenMorse app for the mobile OS.
This app was published on the Google Play Store in mid December, just three weeks after my first contact with Android development.
Additionally to that I learned a bit of JavaScript in 2014 for enhanced features on my websites.
In 2015 I expanded my knowledge by learning Bash, PHP, Python and a little bit of C.
I also released a few font apps for the Cyanogenmod Theme Engine and some bash scripts to make my (and maybe also your) life easier.
Rangitaki is another project that I started in February 2015.
It was a blogging engine without any database dependencies, written in PHP, which tried to be lightweight, extremely fast to start with and easy to use.
Following this passion I joined the Ulm University in October 2015 to studying computer science to further improve my knowledge in this area.
In April 2021 I earned a Bachelor of Science degree in the field of theoretical computer science.
I started learning more and more things about free (as in freedom, not as in free beer) software in the following years.
I strongly support the idea of freedom in software and try to avoid non-free software were possible.
One part of that is my decision to move all my project from GitHub to [[https://gitlab.com/u/mmk2410/projects][GitLab]] and [[https://git.mmk2410.org/explore/repos][my own Gitea instance]].
Due to other activities in the recent years (and also the coming ones) I don't have much time (and currently also not much interested) in developing software.
I try to further maintain some relevant projects, but most of them have been archived.
At the moment, I work as a software developer at a small software agency in Ulm, Germany.
** Photography
I got my first camera back in 2007 when I was ten years old, and this was when I picked up photography as a hobby.
For some reason, taking pictures was always something that motivated me and so I brought my camera with me to many events, holidays and the like during the years.
About 2015/2016, my interest faded a bit, and I focused more on other things, completely forgetting about photography.
In late 2020 this drastically changed when someone gave me an old DLSR camera.
From day one, my passion for photography was back again, and I invested more time than ever.
A bit later, in January 2022, I started an online course to improve my skills further and bought a modern mirrorless camera.
That was also the time when I discovered the more "artsy" side of photography and started sharing my work on social networks like [[https://pixelfed.social/mmk2410][Pixelfed]], [[https://instagram.com/mmk2410][Instagram]], and [[https://vero.co/mmk2410][VERO]].
After a heavy focus on macro photography, I'm currently quite involved in street photography.
If you would like to see some pictures or learn more about that, please visit my [[https://marcelkapfer.photography][portfolio]].
** Graphic Design
I am a huge fan of eye pleasing works!
Therefore I started designing a few years ago, but I hadn't jet time to do any major public work.
As of now my experience narrows down to web design and a little bit of print design, but I currently expand my knowledge by taking online graphic design courses.
** Composing
During my school time I had a lot to do with music and learned to play the piano.
Later I started to focus more on finding my own style, which is is combination of Minimal Music and Impressionism and I also wrote down some scores.
A first piece is written and more or less professionally set and also recorded.
You can download and view both on the [[https://marcel-kapfer.de][composing page]].
Due a lack of time in the last years I didn't have time to compose anything new.
But one other piece is done and only waiting for its recording. Stay tuned!
** Writing
To write about coding, politics, happenings in my life and also philosophy questions is something I'm interested in for years.
Sadly due to many other tasks I wasn't able to write much things.
Next to the blog entries I have also published a few longer [[/manuscripts][manuscripts]].
** Real Life
Away from my desk I loosely follow some hobbies.
On one hand I like to read books of various kinds, including crime novels and science fiction / fantasy stuff but also some technical books.
On the other hand I like visiting mother nature either for cycling, hiking or photographing.
** Others
In case you are interested into what software and hardware I use, you can read my [[/uses][What I Use]] page.

:END:
Since I find the lists of other people about what the use quite interesting and from time to time someone asks my about what software/hardware I use I decided to also set up one.
After having a simple blog post listing software since around 2016 I now put it all together here and update it from time to time.

There are always some ideas floating around in my head of things that I want to write.
Some fade away, and others I capture in my GTD system.
And on some rare occasions, I invest the time to move my thoughts from my brain into a nice blog post.
If you're asking about what I write: I really can't tell.
Most things you can find here at the moment are about Linux, coding, and similar stuff.
But I won't promise that this won't change.
We'll see.

:END:
Since I started to program in 2014 I started a few small software projects.
Sadly over the last years I had nearly no time to maintain any of them (except features and bugfixes I needed).
However, I try to further maintain and develop them.
You can find all of them at [[https://gitlab.com/mmk2410][GitLab]].
** Debian packages and Ubuntu PPAs
My unofficial Debian packages and the corresponding Ubuntu PPA for Jetbrains IntelliJ IDEA are probably the most “famous” thing I have created.
At least I get bug reports and merge requests when I do not update the packages fast enough.
Besides them I also created a few other packages for Debian.
To clarify: I am not a official Debian Developer or Maintainer and am also not formally trained on building Debian packages.
Therefore the quality of the packages is certainly not that good.
There are---more or less---quite hacky.
*** IntelliJ IDEA Community & Ultimate
The community edition and the ultimate edition as well can be received from the Launchpad repository [[https://launchpad.net/~mmk2410/+archive/ubuntu/intellij-idea][ppa:mmk2410/intellij-idea]] which you can add on Ubuntu with
#+begin_src shell
sudo apt-add-repository ppa:mmk2410/intellij-idea # Add the repository
sudo apt-get update # Update the package lists
sudo apt-get install intellij-idea-community # Install IntelliJ IDEA Community
sudo apt-get install intellij-idea-ultimate # and/or install IntelliJ IDEA Ultimate
#+end_src
The source code and the =.deb= packages are available at their repositories on GitLab:
- [[https://gitlab.com/mmk2410/intellij-idea-community/][IntelliJ IDEA Community repository]]
- [[https://gitlab.com/mmk2410/intellij-idea-ultimate/][Intellij IDEA Ultimate repository]]
*** Typefaces
Because I needed them, I packaged three typefaces for Debian.
The packages should also work for Ubuntu but I don't provide an PPA for them.
I currently can not ensure active maintenance of any of these packages.

- *Overpass*: [[https://git.mmk2410.org/deb/fonts-overpass][Gitea]]
** Scorelib (inactive)
Scorelib is a smaller project I started in 2015 for managing my collection music scores (the sheetpapers) with a database.
Scorelib is a CLI program written in Python and using SQlite as a database.
I assume that it only runs on Linux, but I never tested it on other platforms.
Scorelib is, as of now, quite small with only the basic features implemented (like I wrote on the beginning, I had no time to code much the last years).
It is available at [[https://gitlab.com/mmk2410/scorelib][GitLab]].
Note: Although the title says that the project is inactive I do not consider archiving it.
Theoretically I still have a need for such a software but practically time is missing to work on it.
It is also possible that I will start working on it again but then possibly also with a completely different tech stack/goal.
** Other
Smaller scripts that aren't worth their own Git repository can be
found at the [[https://gitlab.com/mmk2410/scirpts][scripts repo]].
** Archived
*** CyanogenMod Fonts (archived)
In early 2015 I created three font packages for the CyanogenMod
Theme Chooser (Comfortaa, Fira Sans and Raleway) which were all
quite a success at Google Play. But since end of 2015 I no longer
own an device for which a CyanogenMode / LineageOS build is
available and so I sadly cannot further develop or maintain those
packages. I /you/ are interested in helping with these projects,
feel free to contact me at me(at)mmk2410(dot)org!
*** Rangitaki (archived)
The biggest project I've started is the Rangitaki blogging engine.
A blogging engine (with a few CMS features) written in PHP and
without database dependencies. I used it prior to this WordPress
installation and still use it on [[https://marcel-kapfer.de][marcel-kapfer.de]].
Read more about it at [[https://gitlab.com/mmk2410/rangitaki/wikis/home][GitLab]].
*** writtenMorse (archived)
writtenMorse was the first project I've started back in 2014. Its
goal is it to provide a Morse code system for writing and reading
(with signs like =#= for a letter space and =+= for a word space)
-- especially at computer system, as well as software to work with
it. The project started with a simple Java program which grow fast
to a full-features software for converting writtenMorse and also
Morse code. The project also created an Android app an a
responsive web app.
More information can still be found at the corresponding [[https://gitlab.com/mmk2410/writtenmorse-specs/wikis/home][wiki
page]].
*** Other archived projects
Beneath those projects there were also a few other ones worth
mentioning like [[https://gitlab.com/mmk2410/filespread][Filespread]], an web app for sending a file to a
group of people via mail, and [[https://gitlab.com/mmk2410/titama][TiTaMa]], a simple time table manager
web app written in PHP (a rewrite in Dart was started and the
backend is complete since mid-2016 but the frontend was never
started). There is also the usual bunch of dead experiments like
an Rangitaki SSH Sync library, written in C with libssh. As of now
all these are no longer developed and archived.

Das hießt aber nicht, dass nie etwas Neues hinzukommt. Es ist gut
möglich, dass ich hier in Zukunft von Zeit zu Zeit ein Zitat poste
und eventuell dieses auch sogar etwas kommentiere. Mal schauen... :D
