 | 
| 559 |     58 |   <A HREF="http://en.wikipedia.org/wiki/Regular_expression">Regular expressions</A> 
 | 
| 549 |     59 |   are extremely useful for many text-processing tasks, such as finding patterns in hostile 
 | 
| 559 |     60 |   <A HREF="https://www.snort.org">network traffic</A>,
 | 
| 520 |     61 |   lexing programs, syntax highlighting and so on. Given that regular expressions were
 | 
| 559 |     62 |   introduced in 1950 by <A HREF="http://en.wikipedia.org/wiki/Stephen_Cole_Kleene">Stephen Kleene</A>,
 | 
| 520 |     63 |   you might think regular expressions have since been studied and implemented to death. But you would definitely be
 | 
|  |     64 |   mistaken: in fact they are still an active research area. On the top of my head, I can give
 | 
|  |     65 |   you at least ten research papers that appeared in the last few years.
 | 
|  |     66 |   For example
 | 
| 559 |     67 |   <A HREF="http://www.home.hs-karlsruhe.de/~suma0002/publications/regex-parsing-derivatives.pdf">this paper</A> 
 | 
| 520 |     68 |   about regular expression matching and derivatives was presented in 2014 at the international 
 | 
| 559 |     69 |   FLOPS conference. Another <A HREF="https://nms.kcl.ac.uk/christian.urban/Publications/posix.pdf">paper</A> by my PhD student and me was presented in 2016
 | 
| 520 |     70 |   at the international ITP conference.
 | 
| 559 |     71 |   The task in this project is to implement these results and use them for lexing.</p>
 | 
| 520 |     72 | 
 | 
| 559 |     73 |   <p>The background for this project is that some regular expressions are 
 | 
|  |     74 |   “<A HREF="http://en.wikipedia.org/wiki/ReDoS#Examples">evil</A>”
 | 
| 520 |     75 |   and can “stab you in the back” according to
 | 
| 559 |     76 |   this <A HREF="http://peterscott.github.io/2013/01/17/regular-expressions-will-stab-you-in-the-back/">blog post</A>.
 | 
|  |     77 |   For example, if you use in <A HREF="http://www.python.org">Python</A> or 
 | 
|  |     78 |   in <A HREF="http://www.ruby-lang.org/en/">Ruby</A> (or also in a number of other mainstream programming languages) the 
 | 
|  |     79 |   innocently looking regular expression <code>a?{28}a{28}</code> and match it, say, against the string 
 | 
|  |     80 |   <code>aaaaaaaaaaaaaaaaaaaaaaaaaaaa</code> (that is 28 <code>a</code>s), you will soon notice that your CPU usage goes to 100%. In fact,
 | 
| 520 |     81 |   Python and Ruby need approximately 30 seconds of hard work for matching this string. You can try it for yourself:
 | 
| 559 |     82 |   <A HREF="http://talisker.inf.kcl.ac.uk/cgi-bin/repos.cgi/afl-material/raw-file/tip/progs/catastrophic.py">catastrophic.py</A> (Python version) and 
 | 
|  |     83 |   <A HREF="http://talisker.inf.kcl.ac.uk/cgi-bin/repos.cgi/afl-material/raw-file/tip/progs/catastrophic.rb">catastrophic.rb</A> 
 | 
|  |     84 |   (Ruby version). Here is a similar problem with the regular expression <code>(a*)*b</code> in Java: 
 | 
|  |     85 |   <A HREF="http://talisker.inf.kcl.ac.uk/cgi-bin/repos.cgi/afl-material/raw-file/tip/progs/catastrophic.java">catastrophic.java</A> 
 | 
|  |     86 |   </p> 
 | 
| 520 |     87 | 
 | 
|  |     88 |   <p>
 | 
|  |     89 |   You can imagine an attacker
 | 
| 559 |     90 |   mounting a nice <A HREF="http://en.wikipedia.org/wiki/Denial-of-service_attack">DoS attack</A> against 
 | 
| 520 |     91 |   your program if it contains such an “evil” regular expression. But it can also happen by accident:
 | 
| 559 |     92 |   on 20 July 2016 the website <A HREF="http://stackstatus.net/post/147710624694/outage-postmortem-july-20-2016">Stack Exchange</A>
 | 
| 520 |     93 |   was knocked offline because of an evil regular expression. One of their engineers talks about this in this
 | 
| 559 |     94 |   <A HREF="https://vimeo.com/112065252">video</A>. A similar problem needed to be fixed in the
 | 
|  |     95 |   <A HREF="http://davidvgalbraith.com/how-i-fixed-atom/">Atom</A> editor.
 | 
| 520 |     96 |   A few implementations of regular expression matchers are almost immune from such problems.
 | 
| 559 |     97 |   For example, <A HREF="http://www.scala-lang.org/">Scala</A> can deal with strings of up to 4,300 <code>a</code>s in less than a second. But if you scale
 | 
|  |     98 |   the regular expression and string further to, say, 4,600 <code>a</code>s, then you get a <code>StackOverflowError</code> 
 | 
| 520 |     99 |   potentially crashing your program. Moreover (beside the "minor" problem of being painfully slow) according to this
 | 
| 559 |    100 |   <A HREF="http://www.haskell.org/haskellwiki/Regex_Posix">report</A>
 | 
| 520 |    101 |   nearly all regular expression matchers using the POSIX rules are actually buggy.
 | 
|  |    102 |   </p>

|  |    103 | 
 | 
| 559 |    104 |   <p>
 | 
| 520 |    105 |   On a rainy afternoon, I implemented 
 | 
| 559 |    106 |   <A HREF="http://talisker.inf.kcl.ac.uk/cgi-bin/repos.cgi/afl-material/raw-file/tip/progs/re3.scala">this</A> 
 | 
| 520 |    107 |   regular expression matcher in Scala. It is not as fast as the official one in Scala, but
 | 
| 559 |    108 |   it can match up to 11,000 <code>a</code>s in less than 5 seconds  without raising any exception
 | 
|  |    109 |   (remember Python and Ruby both need nearly 30 seconds to process 28(!) <code>a</code>s, and Scala's
 | 
|  |    110 |   official matcher maxes out at 4,600 <code>a</code>s). My matcher is approximately
 | 
| 520 |    111 |   85 lines of code and based on the concept of 
 | 
| 559 |    112 |   <A HREF="http://lambda-the-ultimate.org/node/2293">derivatives of regular expressions</A>.
 | 
|  |    113 |   These derivatives were introduced in 1964 by <A HREF="http://en.wikipedia.org/wiki/Janusz_Brzozowski_(computer_scientist)">
 | 
|  |    114 |   Janusz Brzozowski</A>, but according to this
 | 
|  |    115 |   <A HREF="https://www.cs.kent.ac.uk/people/staff/sao/documents/jfp09.pdf">paper</A> had been lost in the “sands of time”.
 | 
| 520 |    116 |   The advantage of derivatives is that they side-step completely the usual 
 | 
| 559 |    117 |   <A HREF="http://hackingoff.com/compilers/regular-expression-to-nfa-dfa">translations</A> of regular expressions
 | 
| 520 |    118 |   into NFAs or DFAs, which can introduce the exponential behaviour exhibited by the regular
 | 
|  |    119 |   expression matchers in Python, Java and Ruby.

 | 
|  |    121 | 
 | 
| 559 |    122 |   <p>
 | 
| 520 |    123 |   Now the authors from the 
 | 
| 559 |    124 |   <A HREF="http://www.home.hs-karlsruhe.de/~suma0002/publications/regex-parsing-derivatives.pdf">FLOPS'14-paper</A> mentioned 
 | 
| 520 |    125 |   above claim they are even faster than me and can deal with even more features of regular expressions
 | 
|  |    126 |   (for example subexpression matching, which my rainy-afternoon matcher cannot). I am sure they thought
 | 
|  |    127 |   about the problem much longer than a single afternoon. The task 
 | 
|  |    128 |   in this project is to find out how good they actually are by implementing the results from their paper. 
 | 
|  |    129 |   Their approach to regular expression matching is also based on the concept of derivatives.
 | 
|  |    130 |   I used derivatives very successfully once for something completely different in a
 | 
| 559 |    131 |   <A HREF="https://nms.kcl.ac.uk/christian.urban/Publications/rexp.pdf">paper</A> 
 | 
|  |    132 |   about the <A HREF="http://en.wikipedia.org/wiki/Myhill–Nerode_theorem">Myhill-Nerode theorem</A>.
 | 
| 520 |    133 |   So I know they are worth their money. Still, it would be interesting to actually compare their results
 | 
|  |    134 |   with my simple rainy-afternoon matcher and potentially “blow away” the regular expression matchers 
 | 
|  |    135 |   in Python, Ruby and Java (and possibly in Scala too). The application would be to implement a fast lexer for
 | 
| 559 |    136 |   programming languages, or improve the network traffic analysers in the tools <A HREF="https://www.snort.org">Snort</A> and

 | 
|  |    142 |   The place to start with this project is obviously this
 | 
| 559 |    143 |   <A HREF="http://www.home.hs-karlsruhe.de/~suma0002/publications/regex-parsing-derivatives.pdf">paper</A>
 | 
|  |    144 |   and this <A HREF="https://nms.kcl.ac.uk/christian.urban/Publications/posix.pdf">one</A>.
 | 
| 520 |    145 |   Traditional methods for regular expression matching are explained
 | 
|  |    146 |   in the Wikipedia articles 
 | 
| 559 |    147 |   <A HREF="http://en.wikipedia.org/wiki/DFA_minimization">here</A> and 
 | 
|  |    148 |   <A HREF="http://en.wikipedia.org/wiki/Powerset_construction">here</A>.
 | 
|  |    149 |   The authoritative <A HREF="http://infolab.stanford.edu/~ullman/ialc.html">book</A>
 | 
| 520 |    150 |   on automata and regular expressions is by John Hopcroft and Jeffrey Ullmann (available in the library). 
 | 
|  |    151 |   There is also an online course about this topic by Ullman at 
 | 
| 559 |    152 |   <A HREF="https://www.coursera.org/course/automata">Coursera</A>, though IMHO not 
 | 
| 520 |    153 |   done with love. 
 | 
|  |    154 |   There are millions of other pointers about regular expression
 | 
|  |    155 |   matching on the Web. I found the chapter on Lexing in this
 | 
| 559 |    156 |   <A HREF="http://www.diku.dk/~torbenm/Basics/">online book</A> very helpful. Finally, it will
 | 
| 520 |    157 |   be of great help for this project to take part in my Compiler and Formal Language module (6CCS3CFL).
 | 
| 559 |    158 |   Test cases for “<A HREF="http://en.wikipedia.org/wiki/ReDoS#Examples">evil</A>”
 | 
|  |    159 |   regular expressions can be obtained from <A HREF="http://www.haskell.org/haskellwiki/Regex_Posix">here</A>.

 | 
|  |    164 |   This is a project for a student with an interest in theory and with
 | 
|  |    165 |   good programming skills. The project can be easily implemented
 | 
|  |    166 |   in functional languages like
 | 
| 559 |    167 |   <A HREF="http://www.scala-lang.org/">Scala</A>,

|  |    168 |   <A HREF="http://fsharp.org">F#</A>,

 |

 | 
| 520 |    171 |   can be also used, but seem much less convenient. If you do attend my Compilers and Formal Languages
 | 
|  |    172 |   module, that would obviously give you a head-start with this project.

 | 
|  |    178 | Parsing is an old nut. Generations of software developers need to do parsing of data or text.
 | 
|  |    179 | There are zillions of links, tools, papers and textbooks about parsing. One particular
 | 
| 559 |    180 | <A HREF="https://dickgrune.com/Books/PTAPG_1st_Edition/BookBody.pdf">book</A> contains something
 | 
| 553 |    181 | like 700 different algorithm, nicely analysed and described. Surely, parsing must be a solved problem. Or is it? 
 | 
| 559 |    182 | Laurie Tratt has a blog <A HREF="https://tratt.net/laurie/blog/entries/parsing_the_solved_problem_that_isnt.html">post</A>
 | 
| 553 |    183 | about <i>Parsing: The Solved Problem That Isn't</i>. IMHO parsing is still a wide open field and not solved at all.
 | 
|  |    184 | PEG parsing, error reporting, error correction, runtime to name just a few are aspects that seem to cause headaches

 | 
| 553 |    189 | (not even published yet) follows an idea for regular expressions: it adapts the notion of 
 | 
|  |    190 | derivatives of regular expressions to grammars. The idea is to implement in a functional programming language
 | 
|  |    191 | the parsing algorithm proposed in this paper and to try it out with some sample data.

 | 
| 553 |    205 | Webassembly is a recently agreed standard for speeding up web applications in browsers. In this

|  |    206 | project the aim is to implement an interpreter or compiler for webassembly. There are already
 | 
| 559 |    207 | <A HREF="https://github.com/WebAssembly/spec/tree/master/interpreter">reference interpreters</A>,
 | 
| 553 |    208 | but people take different views, for example implement a 
 | 
| 559 |    209 | <A HREF="https://groups.google.com/forum/#!topic/comp.lang.forth/CvNrP_AOmmw">Forth</A> language on top of webassembly. 
 | 
| 553 |    210 | What is good about webassembly is that is a rather simple format, which can be generated quite
 | 
|  |    211 | easily, unlike Java class files, which need some head-standing when you generate them.

| 520 |    222 |   Compilers translate high-level programs that humans can read and write into
 | 
|  |    223 |   efficient machine code that can be run on a CPU or virtual machine.
 | 
|  |    224 |   A compiler for a simple functional language generating X86 code is described
 | 
| 559 |    225 |   <A HREF="https://libraries.io/github/chameco/Shade">here</A>.
 | 
| 520 |    226 |   I recently implemented a very simple compiler for an even simpler functional
 | 
|  |    227 |   programming language following this 
 | 
|  |    228 |   <A HREF="https://www.cs.princeton.edu/~dpw/papers/tal-toplas.pdf">paper</A> 
 | 
| 559 |    229 |   (also described <A HREF="https://www.cs.princeton.edu/~dpw/papers/tal-tr.pdf">here</A>).
 | 
|  |    230 |   My code, written in <A HREF="http://www.scala-lang.org/">Scala</A>, of this compiler is 
 | 
|  |    231 |   <A HREF="https://nms.kcl.ac.uk/christian.urban/compiler.scala">here</A>.
 | 
| 520 |    232 |   The compiler can deal with simple programs involving natural numbers, such
 | 
|  |    233 |   as Fibonacci numbers or factorial (but it can be easily extended - that is not the point).
 | 
|  |    234 |   </p>
 | 
|  |    235 | 
 | 
|  |    236 |   <p>
 | 
|  |    237 |   While the hard work has been done (understanding the two papers above),
 | 
|  |    238 |   my compiler only produces some idealised machine code. For example I
 | 
|  |    239 |   assume there are infinitely many registers. The goal of this
 | 
|  |    240 |   project is to generate machine code that is more realistic and can
 | 
|  |    241 |   run on a CPU, like X86, or run on a virtual machine, say the JVM. 
 | 
|  |    242 |   This gives probably a speedup of thousand times in comparison to
 | 
|  |    243 |   my naive machine code and virtual machine. The project
 | 
|  |    244 |   requires to dig into the literature about real CPUs and generating 
 | 
|  |    245 |   real machine code. 
 | 
|  |    246 |   </p>
 | 
|  |    247 |   <p>
 | 
|  |    248 |   An alternative is to not generate machine code, but build a compiler that compiles to
 | 
| 559 |    249 |   <A HREF="http://www.w3schools.com/js/">JavaScript</A>. This is the language that is supported by most
 | 
| 520 |    250 |   browsers and therefore is a favourite
 | 
| 559 |    251 |   vehicle for Web-programming. Some call it <B>the</B> scripting language of the Web.
 | 
| 520 |    252 |   Unfortunately, JavaScript is also probably one of the worst
 | 
| 559 |    253 |   languages to program in (being designed and released in a hurry). <B>But</B> it can be used as a convenient target
 | 
| 520 |    254 |   for translating programs from other languages. In particular there are two
 | 
|  |    255 |   very optimised subsets of JavaScript that can be used for this purpose:
 | 
| 559 |    256 |   one is <A HREF="http://asmjs.org">asm.js</A> and the other is
 | 
|  |    257 |   <A HREF="https://github.com/kripken/emscripten/wiki">emscripten</A>. Since
 | 
|  |    258 |   last year there is even the official <A HREF="http://webassembly.org">Webassembly</A>
 | 
|  |    259 |   There is a <A HREF="http://kripken.github.io/emscripten-site/docs/getting_started/Tutorial.html">tutorial</A> for emscripten
 | 
|  |    260 |   and an impressive <A HREF="https://youtu.be/c2uNDlP4RiE">demo</A> which runs the
 | 
|  |    261 |   <A HREF="http://en.wikipedia.org/wiki/Unreal_Engine">Unreal Engine 3</A>
 | 
| 520 |    262 |   in a browser with spectacular speed. This was achieved by compiling the
 | 
|  |    263 |   C-code of the Unreal Engine to the LLVM intermediate language and then translating the LLVM
 | 
|  |    264 |   code to JavaScript.

 | 
| 520 |    268 |   <B>Literature:</B>
 | 
|  |    269 |   There is a lot of literature about compilers 
 | 
| 559 |    270 |   (for example <A HREF="http://www.cs.princeton.edu/~appel/papers/cwc.html">this book</A> -
 | 
| 520 |    271 |   I can lend you my copy for the duration of the project, or this
 | 
| 559 |    272 |   <A HREF="http://www.diku.dk/~torbenm/Basics/">online book</A>). A very good overview article
 | 
| 520 |    273 |   about implementing compilers by 
 | 
| 559 |    274 |   <A HREF="http://tratt.net/laurie/">Laurie Tratt</A> is 
 | 
|  |    275 |   <A HREF="http://tratt.net/laurie/tech_articles/articles/how_difficult_is_it_to_write_a_compiler">here</A>.
 | 
| 520 |    276 |   An online book about the Art of Assembly Language is
 | 
| 559 |    277 |   <A HREF="http://flint.cs.yale.edu/cs422/doc/art-of-asm/pdf/">here</A>.
 | 
|  |    278 |   An introduction into x86 machine code is <A HREF="http://ianseyler.github.com/easy_x86-64/">here</A>.
 | 
| 520 |    279 |   Intel's official manual for the x86 instruction is 
 | 
| 559 |    280 |   <A HREF="http://download.intel.com/design/intarch/manuals/24319101.pdf">here</A>. 
 | 
|  |    281 |   Two assemblers for the JVM are described <A HREF="http://jasmin.sourceforge.net">here</A>
 | 
|  |    282 |   and <A HREF="https://github.com/Storyyeller/Krakatau">here</A>.
 | 
| 520 |    283 |   An interesting twist of this project is to not generate code for a CPU, but
 | 
| 559 |    284 |   for the intermediate language of the <A HREF="http://llvm.org">LLVM</A> compiler
 | 
|  |    285 |   (also described <A HREF="http://llvm.org/docs/LangRef.html">here</A>). If you want to see
 | 
| 520 |    286 |   what machine code looks like you can compile your C-program using gcc -S.

 | 
| 520 |    288 |   <p>
 | 
| 559 |    289 |   If JavaScript is chosen as a target instead, then there are plenty of <A HREF="http://www.w3schools.com/js/">tutorials</A> on the Web.
 | 
|  |    290 |   <A HREF="http://jsbooks.revolunet.com">Here</A> is a list of free books on JavaScript.
 | 
| 520 |    291 |   A project from which you can draw inspiration is this

 | 
|  |    294 |   And <A HREF="https://github.com/viclib/liscript">another</A> in less than 100 lines of code.
 | 
|  |    295 |   <A HREF="http://en.wikipedia.org/wiki/CoffeeScript">Coffeescript</A> is a similar project
 | 
|  |    296 |   except that it is already quite <A HREF="http://coffeescript.org">mature</A>. And finally not to
 | 
|  |    297 |   forget <A HREF="http://www.typescriptlang.org">TypeScript</A> developed by Microsoft. The main
 | 
| 520 |    298 |   difference between these projects and this one is that they translate into relatively high-level
 | 
| 559 |    299 |   JavaScript code; none of them use the much lower levels <A HREF="http://asmjs.org">asm.js</A> and 
 |

 | 
| 520 |    303 |   <B>Skills:</B> 
 | 
|  |    304 |   This is a project for a student with a deep interest in programming languages and
 | 
| 559 |    305 |   compilers. Since my compiler is implemented in <A HREF="http://www.scala-lang.org/">Scala</A>,
 | 
| 520 |    306 |   it would make sense to continue this project in this language. I can be
 | 
| 559 |    307 |   of help with questions and books about <A HREF="http://www.scala-lang.org/">Scala</A>.
 | 
| 520 |    308 |   But if Scala is a problem, my code can also be translated quickly into any other functional
 | 
|  |    309 |   language. Again,  it will be of great help for this project to take part in
 | 
|  |    310 |   my Compiler and Formal Language module (6CCS3CFL).
 |

 |

 | 
|  |    314 |   <B>PS:</B> Compiler projects consistently received high marks in the past.
 | 
| 520 |    315 |   I have supervised eight so far and most of them received a mark above 70% - one even was awarded a prize.

 | 
| 559 |    320 |   <p>
 | 
| 520 |    321 |   The standard technology for writing scientific papers in Computer Science  is to use
 | 
| 559 |    322 |   <A HREF="http://en.wikipedia.org/wiki/LaTeX">LaTeX</A>, a document preparation
 | 
|  |    323 |   system originally implemented by <A HREF="http://en.wikipedia.org/wiki/Donald_Knuth">Donald Knuth</A>
 | 
|  |    324 |   and <A HREF="http://en.wikipedia.org/wiki/Leslie_Lamport">Leslie Lamport</A>.
 | 
| 520 |    325 |   LaTeX produces very pleasantly looking documents, can deal nicely with mathematical
 | 
| 559 |    326 |   formulas and is very flexible. If you are interested, <A HREF="http://openwetware.org/wiki/Word_vs._LaTeX">here</A>
 | 
| 520 |    327 |   is a side-by-side comparison between Word and LaTeX (which LaTeX “wins” with 18 out of 21 points).
 | 
|  |    328 |   Computer scientists not only use LaTeX for documents,
 | 
|  |    329 |   but also for slides (really, nobody who wants to be cool uses Keynote or Powerpoint).
 | 
| 559 |    330 |   </p>
 | 
| 520 |    331 | 
 | 
| 559 |    332 |   <p>
 | 
| 520 |    333 |   Although used widely, LaTeX seems nowadays a bit dated for producing
 | 
|  |    334 |   slides. Unlike documents, which are typically “static” and published in a book or journal,
 | 
|  |    335 |   slides often contain changing contents that might first only be partially visible and
 | 
|  |    336 |   only later be revealed as the “story” of a talk or lecture demands.
 | 
|  |    337 |   Also slides often contain animated algorithms where each state in the
 | 
|  |    338 |   calculation is best explained by highlighting the changing data.
 | 
|  |    339 |   </p>
 | 
|  |    340 | 
 | 
| 559 |    341 |   <p>
 | 
| 520 |    342 |   It seems HTML and JavaScript are much better suited for generating
 | 
| 559 |    343 |   such animated slides. This <A HREF="http://www.impressivewebs.com/html-slidedeck-toolkits/">page</A>
 | 
| 520 |    344 |   links to slide-generating programs using this combination of technologies. 
 | 
|  |    345 |   However, the problem with all of these project is that they depend heavily on the users being
 | 
|  |    346 |   able to write JavaScript, CCS or HTML...not something one would like to depend on given that
 | 
|  |    347 |   “normal” users likely only have a LaTeX background. The aim of this project is to invent a
 | 
|  |    348 |   very simple language that is inspired by LaTeX and then generate from code written in this language
 | 
|  |    349 |   slides that can be displayed in a web-browser. An example would be the

 | 
| 559 |    353 |  <p>
 | 
| 520 |    354 |  This sounds complicated, but there is already some help available:
 | 
| 559 |    355 |  <A HREF="http://www.mathjax.org">Mathjax</A> is a JavaScript library that can
 | 
|  |    356 |  be used to display mathematical text, for example</p>
 | 
| 520 |    357 | 
 | 
| 559 |    358 |  <blockquote>
 | 
| 520 |    359 |  <p>When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are
 | 
|  |    360 |  \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\).</p>

| 520 |    362 | 
 | 
| 559 |    363 |  <p> 
 | 
| 520 |    364 |  by writing code in the familiar LaTeX-way. This can be reused.
 | 
| 559 |    365 |  Another such library is <A HREF="http://khan.github.io/KaTeX/">KaTeX</A>.
 | 
| 520 |    366 |  There are also plenty of JavaScript
 | 
|  |    367 |  libraries for graphical animations (for example

 | 
|  |    372 |  slides could come from the LaTeX packages <A HREF="http://en.wikipedia.org/wiki/Beamer_(LaTeX)">Beamer</A>

 | 
| 520 |    379 |   This is a project that requires good knowledge of JavaScript. You need to be able to
 | 
|  |    380 |   parse a language and translate it to a suitable part of JavaScript using
 | 
| 559 |    381 |   appropriate libraries. Tutorials for JavaScript are <A HREF="http://www.w3schools.com/js/">here</A>.
 | 
|  |    382 |   A parser generator for JavaScript is <A HREF="http://pegjs.majda.cz">here</A>. There are probably also
 | 
| 520 |    383 |   others. If you want to avoid JavaScript there are a number of alternatives: for example the

|  |    438 |   There are essentially two kinds of projects: One is purely software-based. Software projects for Raspberry Pi's are often
 | 
| 559 |    439 |   written in <A HREF="http://www.python.org">Python</A>, but since these are Linux-capable computers any other
 | 
| 520 |    440 |   language would do as well. You can also write your own operating system as done
 | 
| 559 |    441 |   <A HREF="http://www.cl.cam.ac.uk/projects/raspberrypi/tutorials/os/">here</A>. For example the students
 | 
|  |    442 |   <A HREF="http://www.recantha.co.uk/blog/?p=4918">here</A> developed their own bare-metal OS and then implemented
 | 
| 520 |    443 |   a chess-program on top of it (have a look at their very impressive
 | 
| 559 |    444 |   <A HREF="http://www.youtube.com/watch?v=-03bouPsfEQ&feature=player_embedded">youtube</A> video).
 | 
| 520 |    445 |   The other kind of project is a combination of hardware and software; usually attaching some sensors
 | 
|  |    446 |   or motors to the Raspberry Pi or Arduino. This might require some soldering or what is called
 | 
| 559 |    447 |   a <A HREF="http://en.wikipedia.org/wiki/Breadboard">bread-board</A>. But be careful before choosing a project
 | 
| 520 |    448 |   involving new hardware: these devices
 | 
|  |    449 |   can be destroyed (if “Vin connected to GND” or “drawing more than 30mA from a GPIO”
 | 
|  |    450 |   does not make sense to you, you should probably stay away from such a project).

 | 
| 520 |    473 |   Well, you must be a hacker; happy to make things. Your desk might look like the photo below on the left.
 | 
|  |    474 |   The photo below on the middle shows an earlier student project which connects wirelessly a wearable Arduino (packaged
 | 
|  |    475 |   in a "self-3d-printed" watch) to a Raspberry Pi seen in the background. The Arduino in the foreground takes
 | 
|  |    476 |   measurements of 
 | 
|  |    477 |   heart rate and body temperature; the Raspberry Pi collects this data and makes it accessible via a simple
 | 
|  |    478 |   web-service. The picture on the right is another project that implements an airmouse using an Arduino.

 | 
|  |    498 |     A really cool project using a toy helicopter and two Raspberry Pi's was done by Nikolaos Kyknas. He transformed
 | 
|  |    499 |     an off-the-shelf toy helicopter into an autonomous flying machine. He attached a Raspberry Pi Zero and an ultrasound
 | 
|  |    500 |     sensor to the helicopter for measuring the distance from ground. Another Raspberry Pi is attached to the “ground control
 | 
|  |    501 |     unit” in order to give instructions to the throttle of the helicopter. Both Raspberry Pi's communicate over WiFi for calculating
 | 
| 538 |    502 |     the next flight instruction. The goal is to find and maintain a steady altitude. Sounds simple? Well, not so fast! 
 | 
|  |    503 |     First you need to get the balance of the helicopter plus Raspberry Pi plus its power source just right,
 | 
| 537 |    504 |     otherwise the helicopter will simply take off in random directions. Also the flight instructions need to be just right,
 | 
| 538 |    505 |     otherwise the helicopter would at best “oscillate” around the set altitude, but never be steady. To solve this problem, 
 | 
| 537 |    506 |     Nikolaos used exactly the same algorithm that keeps cars at a steady pace when in cruise control.

 | 
|  |    522 |   <B>Description:</B>
 | 
| 520 |    523 |   The project aim is to implement an infrastructure for displaying and
 | 
|  |    524 |   animating code in a web-browser. The infrastructure should be agnostic
 | 
|  |    525 |   with respect to the programming language, but should be configurable.
 | 
|  |    526 |   I envisage something smaller than the projects 
 |

| 520 |    534 | 
 | 
|  |    535 |   <p>
 | 
|  |    536 |   The tasks in this project are being able (1) to lex and parse languages and (2) to write an interpreter.
 | 
|  |    537 |   The goal is to implement this as much as possible in a language-agnostic fashion.

 | 
|  |    540 |   <p>
 | 
| 559 |    541 |   <B>Skills:</B> 
 | 
| 520 |    542 |   Good skills in lexing and language parsing, as well as being fluent with web programming (for
 | 
|  |    543 |   example JavaScript).

 | 
| 520 |    548 | 
 | 
| 559 |    549 |  <p>
 | 
| 520 |    550 |  I am one of the main developers of the interactive theorem prover
 | 
| 559 |    551 |  <A HREF="http://isabelle.in.tum.de">Isabelle</A>. This theorem prover
 | 
| 520 |    552 |  has been used to establish the correctness of some quite large
 | 
| 559 |    553 |  programs (for example an <A HREF="http://ertos.nicta.com.au/research/l4.verified/">operating system</A>).
 | 
| 520 |    554 |  Together with colleagues from Nanjing, I used this theorem prover to establish the correctness of a
 | 
|  |    555 |  scheduling algorithm, called
 | 
| 559 |    556 |  <A HREF="http://en.wikipedia.org/wiki/Priority_inheritance">Priority Inheritance</A>,
 | 
| 520 |    557 |  for real-time operating systems. This scheduling algorithm is part of the operating
 | 
|  |    558 |  system that drives, for example, the 
 | 
| 559 |    559 |  <A HREF="http://en.wikipedia.org/wiki/Mars_Exploration_Rover">Mars rovers</A>.
 | 
| 520 |    560 |  Actually, the very first Mars rover mission in 1997 did not have this
 | 
|  |    561 |  algorithm switched on and it almost caused a catastrophic mission failure (see
 | 
| 559 |    562 |  this youtube video <A HREF="http://www.youtube.com/watch?v=lyx7kARrGeM">here</A>
 | 
| 520 |    563 |  for an explanation what happened).
 | 
|  |    564 |  We were able to prove the correctness of this algorithm, but were also able to
 | 
|  |    565 |  establish the correctness of some optimisations in this
 | 
| 559 |    566 |  <A HREF="https://nms.kcl.ac.uk/christian.urban/Publications/pip.pdf">paper</A>.
 | 
|  |    567 |  </p>
 | 
| 520 |    568 | 
 | 
| 559 |    569 |  <p>On a much smaller scale, there are a few small programs and underlying algorithms where it
 | 
| 520 |    570 |  is not really understood whether they always compute a correct result (for example the
 | 
|  |    571 |  regular expression matcher by Sulzmann and Lu in project [CU1]). The aim of this
 | 
|  |    572 |  project is to completely specify an algorithm in Isabelle and then prove it correct (that is,
 | 
|  |    573 |  it always computes the correct result).
