-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
 
   The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,

-any other work released this way by its authors.  You can apply it to

   When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
@@ -26,44 +24,34 @@ them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
 
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
 
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.

+        <p>Welcome to my website, visitor {{ visitor }}!</p>
+
+        <p>
+            My name is <b>Ari Archer</b> also known as <b>Arija A.</b>, but most commonly referred to as
+            <b>Ari</b>. I am a {{ ari_age }} year old, neurodivergent, transgender, open source developer from Lithuania who does
+            fun stuff in primarily <a target="_blank" href="https://en.wikipedia.org/wiki/Python_(programming_language)">Python</a> (~{{ python_exp }} years)
+            and <a target="_blank" href="https://en.wikipedia.org/wiki/C_(programming_language)">C (89, 99)</a> (~{{ c_exp }} years).
+        </p>
+
+        <p>
+            I've picked up programming at first in Python, writing various programs on my phone, and later on discovering a communty
+            where I could share my code. At the time I didn't have access to a computer, so I used to play around with
+            basic <a target="_blank" href="https://en.wikipedia.org/wiki/JavaScript">JavaScript</a> on my local library computers.
+            At around 2019 I got access to a personal computer, which is where my main <a target="_blank" href="https://en.wikipedia.org/wiki/Free_and_open-source_software">FOSS</a> journey started -
+            exploring more technologies and understanding them more in-depth, not being limited by a locked down phone.
+        </p>
+
+        <p>
+            I hated the limiting feeling of being on <a target="_blank" href="https://en.wikipedia.org/wiki/Microsoft_Windows">Microsoft Windows</a> 10
+            very limiting, so soon after getting a personal computer I installed a free and open source <a target="_blank" href="https://en.wikipedia.org/wiki/Linux">Linux</a>
+            kernel distribution - and I've never went back to Windows ever since then. Democracy, freedom, shareability
+            and customization ("hackability") are huge values for me.
+        </p>
+
+        <p>
+            Technology is a big part of my life, and I am way past the stage where I find <i>just</i> technology facinating -
+            I find various problems and their optimal solutions very interesting and I like to come up with my own - even if
+            it's "<a target="_blank" href="https://en.wikipedia.org/wiki/Reinventing_the_wheel">reinventing the wheel</a>" or "impractical" -
+            I like to dig deep into it and understand how it works at its core, rather than relying on high-level features of an
+            abstraction stack. I was always a person like this, not specifically in technology - I was always the nerdy science kid -

+            Even though I'd consider technology, problem solving, and computer programming a big part of my life, I
+            also enjoy a couple of more things. Such as:
+        </p>
+
+        <ul>
+            <li>Exploring various social issues (wars, injustice, freedom of people, abuse, discrimination, environmental problems, ...)</li>
+            <li>Cooking - I really enjoy putting together a healthy, vegan dish, which's recipe I can share with others.</li>
+            <li>And also <a href="https://blog.ari.lt/">blogging</a>, as archiving things and <i>thoughts</i> has been a huge part of my life since forever.</li>
