+Freedom/security aspects and the operating systems I use
+--------------------------------------------------------
`I try to use as much free software as possible <{filename}/why_free_software.rst>`_. Unfortunately, we are not yet at the point when we can buy almost any kind of hardware as use it exclusively with free software. My laptop and PC work fine with the free graphics drivers for Intel and Nvidia chips. On the operating system level, I don't depend on nonfree software in the case of the PC, home server and router. However, the laptop needs a nonfree firmware to make the Intel Wireless card work.
My PC, laptop and home server need proprietary hardware initialization software. There isn't a free `BIOS <https://en.wikipedia.org/wiki/BIOS>`_ replacement available yet. I'd like to use hardware that is supported by `Libreboot <https://libreboot.org/>`_ or at least supported by `Coreboot <https://www.coreboot.org/>`_. The `Libreboot website <https://libreboot.org/>`_ explains why it's important that free software boots up your system. It also sums up why security and privacy is only possible on `Intel <https://libreboot.org/faq/#intel>`_ and `AMD <https://libreboot.org/faq/#amd>`_ hardware that is several years old.

A nonfree BIOS causes several issues. Among others, many manufacturers use whitelists to only allow the usage of a certain hardware. This makes it difficult to replace parts of the hardware. The nonfree BIOS is often slow and bloated. It may contain backdoors Security issues are
-More coming soon!
+Unfortunately, my two phones also need proprietary initialization software. The bootloaders are not even replaceable because the hardware only runs bootloaders that are signed by the manufacturer. `There is also a second nonfree operating system running on the modem and various chips need proprietary firmwares for which there are no free replacements yet <https://redmine.replicant.us/projects/replicant/wiki/GalaxyS3I9300PrivacySecurityEvaluation>`_. The `Replicant website <https://www.replicant.us/freedom-privacy-security-issues.php>`_ explains why these issues need our attention. The graphics chip and GPS even need proprietary drivers that run on the main CPU. I use a QSTARZ BT-Q818XT as external GPS receiver over Bluetooth. It is quite accurate, has a long battery life and works nicely with my updated `BlueGPS <https://code.fossencdi.org/BlueGPS.git/>`_ app version. I don't use any proprietary drivers or other software that runs on the main CPU of the phone, but I use some proprietary firmware to get different functionality working.
+
+The two servers, the PC and the laptop are running `Debian Stable <https://www.debian.org/>`_. I tried many different `distributions <http://distrowatch.com/>`_, but I always came back to Debian. It has a huge community, focuses on free software and is just stable and secure. The router is running `Openwrt <https://openwrt.org/>`_. `Replicant 6.0 <https://redmine.replicant.us/boards/21/topics/12057>`_ powers the phones.
+
+I use various tools to make my desktops and servers more secure and to reduce the maintenance burden. For example, I make heavy use of AppArmor to confine critical or Internet-facing applications. `Here <https://code.fossencdi.org/config.git/tree/apparmor-profiles>`_ are some of my customized profiles. My kernels are hardened with `grsecurity <https://grsecurity.net/>`_ including PaX.
+
+Desktop
+-------
+For some time, I switched between `Xfce <https://www.xfce.org/>`_, `KDE's Plasma Desktop <https://www.kde.org/workspaces/plasmadesktop/>`_ and `GNOME 3 <https://www.gnome.org/gnome-3/>`_ as my desktop environment of choice. Quite some time ago, I settled with `i3 <https://i3wm.org/>`_ which is not even a desktop environment but an awesome tiling window manager. It is very lightweight, fast and makes a completely keyboard-driven workflow possible. `Here <https://code.fossencdi.org/config.git/tree/i3-config>`__ is my config file. `LightDM <https://www.freedesktop.org/wiki/Software/LightDM/>`_ is my favorite display manager and `urxvt <http://software.schmorp.de/pkg/rxvt-unicode.html>`_ is my default terminal. `/r/unixporn <https://www.reddit.com/r/unixporn/>`_ is a great source for nice-looking customizations for i3 and urxvt. `I use Emacs for almost all text-related tasks <{filename}/pages/notes.rst#emacs>`_.
+
+Of course, `my photo and video editing workflow only involves free software <{filename}/pages/notes.rst#media>`_, although some of my older `photos <https://fossencdi.org/gallery/index.html>`_ were edited with nonfree software because I wasn't yet aware about free software at the time. Sometimes, I use a Wacom Bamboo tablet for editing photos, creating vector graphics or annotating documents in `Xournal <http://xournal.sourceforge.net/>`_. `qpdfview <https://launchpad.net/qpdfview>`_ is my go-to PDF viewer because it makes it possible to open many PDF files in a tabbed view and it syncs nicely a PDF preview of my `LaTeX <https://www.latex-project.org/>`_ documents.
+
+My music is handled by `MPD <https://www.musicpd.org/>`_. It's a daemon that can be accessed by different interfaces. On the desktop, I use `ncmpcpp <https://rybczak.net/ncmpcpp/>`_. On the phone, I stream music from my PC with `MPDroid <https://github.com/abarisain/dmix>`_. I like about MPD that it practically always plays my music without any hiccups, even when the machine is under full load including heavy disc IO.
+
+`youtube-dl <https://rg3.github.io/youtube-dl/>`_ in combination with `mpv <https://mpv.io/>`_ and `MediathekView <http://zdfmediathk.sourceforge.net/>`_ are used to access videos that are available on the Internet. My IRC setup consists of `WeeChat <https://weechat.org/>`_ and `ZNC <http://wiki.znc.in/ZNC>`_. `pass <https://www.passwordstore.org/>`_ stores all my passwords. The ugly but extremely handy `Ding dictionary lookup program <https://www-user.tu-chemnitz.de/~fri/ding/>`_ is my dictionary and thesaurus interface.
+
+Self-hosting
+------------
+In my experience, setting up email processing is the most difficult part of a self-hosted setup. On the servers, my mail is handled by `Postfix <http://www.postfix.org/>`_, `Dovecot <http://dovecot.org/>`_, `amavisd-new <https://www.amavis.org/>`_, `SpamAssassin <https://spamassassin.apache.org/>`_, `Postgrey <http://postgrey.schweikert.ch/>`_, `Roundcube <https://roundcube.net/>`_ and `ClamAV <https://www.clamav.net/>`_. Everything is glued together with MySQL.
+
+On my home server, `Tiny Tiny RSS <https://tt-rss.org/gitlab/fox/tt-rss/wikis/home>`_ aggregates all my various reading sources including news, blogs, comics and software updates. I also have an `ownCloud <https://owncloud.org/>`_ instance running, but it's only used to share files with others. I do my own file syncing with `git-annex <https://git-annex.branchable.com/>`_. Calendar and contacts are synced with `Radicale <http://radicale.org/>`_. I also maintain an `Etherpad <http://etherpad.org/>`_ instance for notes and to work together with others on documents. `Prosody <https://prosody.im/>`_ works best for me as a Jabber/XMPP server. Besides `Tor <https://www.torproject.org/>`_, I experiment with `I2P <https://geti2p.net/en/>`_, especially with the file sharing part of it. `BIND <https://www.isc.org/downloads/bind/>`_ does my DNS, but shame on me: I still didn't have the time to set up `DNSSEC <https://en.wikipedia.org/wiki/Dnssec>`_ and `DANE <https://en.wikipedia.org/wiki/DNS-based_Authentication_of_Named_Entities>`_.
+
+Together with the services that are hosted `here <https://fossencdi.org>`__, I am able to self-host every service that I need and that involves my personal data.

You may have heard the term "open source" for what I call free software. `Others <https://www.gnu.org/philosophy/open-source-misses-the-point.html>`_ and I don't use that term as it only puts the emphasis on one property of the software and not the part that is most important to me: freedom.

This behavior of the media boosts the societal segregation. Everyone that keeps in line will have difficulties to form their own opinion due to lack of details and perspectives. Furthermore, she or he is encouraged to not worry and do something about our problems because there are already good people working on solving them. Everyone who comes to different conclusions and wants a discussion is alienated by the hostility. This leads to the many forms of radicalization we see today. People are breaking out of the bubble. But instead of trying to get a more complete world view, they seek a new bubble where everyone has their opinion and detests everyone else that doesn't have their opinion. They are just following the path of least resistance.
-I had hoped that the Internet would change something about this. In fact, the group of the well informed seems greater than ever and investigative journalists have numerous sources. Activists have it much easier to organize themselves. But it's also easier than ever to find someone that confirms the craziest claims and biggest lies. Sources are either not checked at all or in a very sloppy way. If someone we know and trust shares a story on social media, then it has to be true and we don't need to read more than the headline. So while the internet fosters knowledge and communication, it also helps to gather people in their own little radical groups and pushes us more apart. Maybe the Internet is just too complex or it still costs too much effort to do proper research on current topics?

Maybe people need to be taught how to do the research itself and handle the vast amounts of different sources we have today. For sure, lack of time plays a role, too. Besides all the working and self-optimizing we have to do, there are not much time and mental resources left to follow up on what is going on. More political influence for everyone in the sense of direct democracy may also improve the situation, but only if everyone is well educated on the issues and seeks discourse. Otherwise, it will probably lead to more uninformed decisions, more frequent policy changes and more harm to everyone.
