+\textbf{Gancarz:}
+-- small is beautiful
+-- make each program do one thing well
+-- use software leverage to your advantage
+-- avoid captive user interfaces
+-- make every program a filter
+\dots
+}
+\frame{ \frametitle{Recap: The Unix Philosophy (2)}
+\textbf{McIlroy:}
+-- write programs that do one thing and do it well
+-- write programs to work together
+-- write programs to handle text streams
+}
+\frame{ \frametitle{modern web browsers}
+\dots\ are not small
+\hfill\ (huge amounts of code)
+% how many SLOC
+\pause
+\dots\ do not do one thing
+\hfill\ (include lots of stuff)
+% browse, bookmarks, download, news feeds
+\pause
+\dots\ do not use software leverage
+\hfill\ (do not use available tools)
+% no use of wget, newsbeuter
+\pause
+\dots\ have captive user interfaces
+\hfill\ (do not fit into the Unix UI)
+% explains itself, ^U, ^W
+\pause
+\dots\ are no filters
+\hfill\ (what about html2text?)
+% no combination, they are monolithic blocks
+\pause
+\dots\ do not work together
+\hfill\ (everything's already included)
+% as above
+\pause
+\dots\ do not handle text streams
+\hfill\ (have no interfaces anyway)
+% as above
+\pause
+\textbf{$\Rightarrow$ They do completely conflict with the Unix Philosophy!}

+\frame{ \frametitle{Three problems to solve}
+1) user interface
+2) size, simplicity
+3) software leverage, combination, filters
+}
+\frame{ \frametitle{Problem 1: user interface}
+already addressed (e.g. by vimperator)
+pretty easy to implement
+but/only a user-side problem
+}
+\frame{ \frametitle{Problem 2: size, simplicity}
+suckless community's limit: 10k SLOC
+\pause
+but:\\
+-- gecko (xulrunner-1.9: 2.6m SLOC)\\
+-- webkit (webkit-1.1: 390k SLOC)\\
+-- khtml (gtkhtml-2.8: 70k SLOC)
+(now imagine 0.1--10 bugs/KLOC)
+\pause
+simplicity is not possible because of today's web ($\rightarrow$ digression)
+}
+\frame{ \frametitle{digression: today's web}
+\dots\ is broken!
+\pause
+-- state in a state-less technology (deep-links, back-button)
+-- misused technologies (flash)
+-- totally overloaded, much too complex
+\pause
+$\Rightarrow$ simple render engines are not possible anymore
+$\Rightarrow$ web browsers have no chance -- they are essentially complex
+}
+\frame{ \frametitle{Problem 3: software leverage, combination, filters}
+this is the point to put hands on
+\pause
+-- why should the bookmark management be \textbf{inside} the browser?
+-- why does the browser need an \textbf{own} download manager?
+\pause
+$\Rightarrow$ better: use external programs that are available!
+}
+\frame{ \frametitle{How could it look like}
+-- take one of the bloated render engines (black box)
+\pause
+-- wrap it into a small program with software leverage in mind
+\pause
+-- have interfaces to refer to \textbf{external} programs
+\pause
+-- add a good user interface
+}
+\frame{ \frametitle{Examples (1)}
+\textbf{uzbl}
+\texttt{http://uzbl.org}
+by Dieter Plaetinck (Dieterbe)
+since 2009-04
+started as {\small \texttt{http://bbs.archlinux.org/viewtopic.php?id=67463}}
+2\,700/1\,100 SLOC (2\,300/280 SLOC in May)
+is quite active (various branches)
+impressive work was achieved in short time
+}
+\frame{ \frametitle{Examples (2)}
+\textbf{surf}
+\texttt{http://surf.suckless.org}
+by Enno Boland (Gottox)
+since 2009-06
+500 SLOC
+minimalistic reimplementation of uzbl !?
+like uzbl was in the very beginning
+}
+\frame{ \frametitle{5 steps to improve the software world}
+1) understand: the Unix Philosophy!
+\pause
+2) realize: a lot of modern software does not comply
+\pause
+3) realize: it's mostly the same kinds of problems
+\pause
+4) realize: it can be done better
+\pause
+5) do it better!
+\pause
+$\Rightarrow$ write, help, use sane software!
+}
+\frame{
+software used:\\
+-- Debian GNU/Linux\\
+-- LaTeX beamer, latexmk, fbgs\\
+-- vim, sloccount, mercurial
