84 % how many SLOC

141 \frame{ \frametitle{Problem 1: user interface}
143 already addressed (e.g. by vimperator)
145 pretty easy to implement
147 but/only a user-side problem

155 suckless community's limit: 10k SLOC
156 \pause
159 but:\\
160 -- gecko (xulrunner-1.9: 2.6m SLOC)\\
161 -- webkit (webkit-1.1: 390k SLOC)\\
162 -- khtml (gtkhtml-2.8: 70k SLOC)

167 simplicity is not possible because of today's web ($\rightarrow$ digression)

176 \dots\ is broken!
177 \pause
179 -- state in a state-less technology (deep-links, back-button)
181 -- misused technologies (flash)
183 -- totally overloaded, much too complex
184 \pause
186 $\Rightarrow$ simple render engines are not possible anymore
188 $\Rightarrow$ web browsers have no chance -- they are essentially complex
190 }
194 \frame{ \frametitle{Problem 3: software leverage, combination, filters}
196 this is the point to put hands on
197 \pause
199 -- why should the bookmark management be \textbf{inside} the browser?
201 -- why does the browser need an \textbf{own} download manager?
202 \pause
204 $\Rightarrow$ better: use external programs that are available!
206 }
210 \frame{ \frametitle{How could it look like}
212 -- take one of the bloated render engines (black box)
213 \pause
215 -- wrap it into a small program with software leverage in mind
216 \pause
218 -- have interfaces to refer to \textbf{external} programs
219 \pause
221 -- add a good user interface

228 \textbf{uzbl}
230 \texttt{http://uzbl.org}
232 by Dieter Plaetinck (Dieterbe)
234 since 2009-04
236 started as {\small \texttt{http://bbs.archlinux.org/viewtopic.php?id=67463}}
238 2\,700/1\,100 SLOC (2\,300/280 SLOC in May)
240 is quite active (various branches)
242 impressive work was achieved in short time

247 \frame{ \frametitle{Examples (2)}
249 \textbf{surf}
251 \texttt{http://surf.suckless.org}
253 by Enno Boland (Gottox)
255 since 2009-06
257 500 SLOC
259 minimalistic reimplementation of uzbl !?
261 like uzbl was in the very beginning
263 }
266 \frame{ \frametitle{5 steps to improve the software world}
268 1) understand: the Unix Philosophy!
269 \pause
271 2) realize: a lot of modern software does not comply
272 \pause
274 3) realize: it's mostly the same kinds of problems
275 \pause
277 4) realize: it can be done better
278 \pause
280 5) do it better!
281 \pause
283 $\Rightarrow$ write, help, use sane software!
