+ \begin{quote}
+ \enquote{The Windows API is so broad, so deep, and so functional that most independent software vendors would be crazy not to use it. And it is so deeply embedded in the source code of many Windows apps that there is a huge switching cost to using a different operating system instead... It is this switching cost that has given the customers the patience to stick with Windows through all our mistakes, our buggy drivers, our high TCO (total cost of ownership), our lack of a sexy vision at times, and many other difficulties [...] Customers constantly evaluate other desktop platforms, [but] it would be so much work to move over that they hope we just improve Windows rather than force them to move. In short, without this exclusive franchise called the Windows API, we would have been dead a long time ago.}

+# Notes FOSS talk
+
+## Definition
+
+Free meaning
+
+- free as in free speech vs. free as in free beer
+- often, the term "libre" is used to make this clear
+- you can still earn money with free software
+
+open source meaning
+
+- this is what we call code
+- this is readable by humans, provided they know the language
+- you can kinda see what this does
+- this is not readable for a computer
+
+binary
+
+- this is what the computer can execute
+- text stuff is still visible
+- very hard to reverse-engineer and see how it works
+
+## history
+
+early computing
+
+- scientific hacking culture
+- software was delivered alongside the machine
+- the source code was delivered as well
+- the scientists had to adapt software for their needs
+
+proprietary software
+
+- larger software
+- started to only ship the binary
+- two big events
+- lawsuit was dropped --> bundled software is now okay
+- patentable software --> software is very young --> 25 years is A LOT
+
+fsf
+
+- four freedoms
+- based on moral points
+- they are a little dogmatic
+- they don't do compromises
+
+osi
+
+- sells open source as a convenience rather than a moral obligation
+- they are less harsh on the defintion
+- free software is always open source, but not vice versa
+
+foss
+
+- thus, we stick the two words together and call it foss
+- people also call it "FLOSS" (libre), but this is kind of a silly word
+
+gpl
+
+- if software is free or open depends on the license
+- software has per se a copyright protection
+- with a license, you state how your software has to be used
+- gpl based on four freedoms of fsf
+
+bsd license
+
+- this is a bit of a full slide, but this is the whole license text
+- it basically says:
+ - you can do with the software whatever you want
+ - if this software is used for evil, the writer is not at fault
+
+copyleft
+
+- the main difference between the two is the copyleft (a joke from copyright)
+- modified gpl source code has to be redistributed under gpl as well
+- example: linux, many forked linux and added their own stuff, and linux could just take this code
+
+performance
+
+- linus' law
+- it was discovered that it doesn't scale well with large numbers of people, but the principle still holds
+- even if you are not a coder, someone else is
+- if malicious stuff is found, one can fork the code and remove that
+
+software habits
+
+- your software license cannot be taken away
+
+signal vs. whatsapp
+
+ Subscriber name
+ Payment information
+ Associated IP addresses
+ Email addresses
+ History logs
+ Browser cookie data
+ Other information associated with two phone numbers

+ \enquote{The Windows API is so broad, so deep, and so functional that most independent software vendors would be crazy not to use it. And it is so deeply embedded in the source code of many Windows apps that there is a huge switching cost to using a different operating system instead... It is this switching cost that has given the customers the patience to stick with Windows through all our mistakes, our buggy drivers, our high TCO (total cost of ownership), our lack of a sexy vision at times, and many other difficulties [...] Customers constantly evaluate other desktop platforms, [but] it would be so much work to move over that they hope we just improve Windows rather than force them to move. In short, without this exclusive franchise called the Windows API, we would have been dead a long time ago.}

+
+
+ \begin{frame}{Embrace, Extend, Extinguish: Example}
+ \begin{itemize}
+ \item \textcolor{ldorange}{Embrace:} Google joining the browser market with Chrome/Chromium
+ \item \textcolor{ldorange}{Extend:} Add proprietary features that are not standard-compliant. Google apps use these features, leading to compatibility problems on other browsers.
+ \item \textcolor{ldorange}{Extinguish:}
+ \begin{itemize}
+ \item Developers don't test their applications on other browsers
+ \item Applications break
+ \item Other browsers lose market share due to \enquote{being bad}
+ \end{itemize}
+ \end{itemize}
+ \end{frame}
+
+ \begin{frame}{Regulation from within} % TODO: more info
+ E.g. \textit{via} political \enquote{Codes of Conduct}, which can:

+# Notes FOSS talk
+
+## Definition
+
+Free meaning
+
+- free as in free speech vs. free as in free beer
+- often, the term "libre" is used to make this clear
+- you can still earn money with free software
+
+open source meaning
+
+- this is what we call code
+- this is readable by humans, provided they know the language
+- you can kinda see what this does
+- this is not readable for a computer
+
+binary
+
+- this is what the computer can execute
+- text stuff is still visible
+- very hard to reverse-engineer and see how it works
+
+## history
+
+early computing
+
+- scientific hacking culture
+- software was delivered alongside the machine
+- the source code was delivered as well
+- the scientists had to adapt software for their needs
+
+proprietary software
+
+- larger software
+- started to only ship the binary
+- two big events
+- lawsuit was dropped --> bundled software is now okay
+- patentable software --> software is very young --> 25 years is A LOT
+
+fsf
+
+- four freedoms
+- based on moral points
+- they are a little dogmatic
+- they don't do compromises
+
+osi
+
+- sells open source as a convenience rather than a moral obligation
+- they are less harsh on the defintion
+- free software is always open source, but not vice versa
+
+foss
+
+- thus, we stick the two words together and call it foss
+- people also call it "FLOSS" (libre), but this is kind of a silly word
+
+gpl
+
+- if software is free or open depends on the license
+- software has per se a copyright protection
+- with a license, you state how your software has to be used
+- gpl based on four freedoms of fsf
+
+bsd license
+
+- this is a bit of a full slide, but this is the whole license text
+- it basically says:
+ - you can do with the software whatever you want
+ - if this software is used for evil, the writer is not at fault
+
+copyleft
+
+- the main difference between the two is the copyleft (a joke from copyright)
+- modified gpl source code has to be redistributed under gpl as well
+- example: linux, many forked linux and added their own stuff, and linux could just take this code
+
+performance
+
+- linus' law
+- it was discovered that it doesn't scale well with large numbers of people, but the principle still holds
+- even if you are not a coder, someone else is
+- if malicious stuff is found, one can fork the code and remove that
+
+software habits
+
+- your software license cannot be taken away
+
+signal vs. whatsapp
+
+ Subscriber name
+ Payment information
+ Associated IP addresses
+ Email addresses
+ History logs
+ Browser cookie data
+ Other information associated with two phone numbers

+ \item \textbf{Installing Software} is not done by downloading stuff with your browser. You'll find (almost) everything in the software store preinstalled on your distribution. It is like on your phone, where you download apps from the store.
\item There are a few programs which \textbf{do not work} on Linux. The most important of which are Microsoft Word, Excel, PowerPoint and OneNote, as well as all Adobe products. You'll find suitable replacements at the end of this document.
\item If you run into problems, just look them up online. Really. There's a huge amount of documentation and questions/answers by other users. If you don't find any helpful information, just ask us on \url{https://thealternative.ch}.
\end{enumerate}

+
+Partitioning the hard drive and installing a new operating system always carries the risk of data loss. Therefore, make sure that you have an up-to-date backup of all the data that is important to you.
