1. The Latin Modern fonts project was begun in 2002 Based on Computer Modern the Latin Modern family currently consist of seventy two text and twenty math fonts available in both OpenType and PostScript Type 1 formats The Gyre font project that was begun in 2006 aims to supplement the thirty three URW fonts distributed with GhostScript to cover all Latin languages similarly as the LM fonts do Hinting is improved and files in OpenType format are provided Extensions to the math capabilities are planned for the near future Here are those TEX Gyre fonts which have already been given new names Original name Gyre name Avantgarde Adventor Bookman Bonum Courier Cursor Helvetica Heros Palatino Pagella Century Schoolbook Schola Times Termes Zaph Chancery Chorus The Latin Modern and Gyre project pages are found on the http www gust org pl website The re spective folders are projects e foundry latin modern and projects e foundry tex gyre Michael Guravage Recalling Niklaus Wirth s statement that algorithms plus data structures equal programs Marek Ry ko demonstrated how to realise Lisp like structures and methods in TEX Marek argued that a clean and consistent approach to handling lists of elements will make programming TEX simpler and TEX programs i e macros more reliable Jerzy Ludwichowski concluded the conference pro ceedings by thanking the organizers authors and participant

6. large quantities of special paper were needed keep in mind that he gave away a free copy to each of the more than 2000 Dante members Other interesting differences between the versions are in paragraph breaks and whitespace As with Dutch German needs a few more words than English to express ideas but the general impression is that the German version is the most informative Other subtle differences are in the used technical terms The English version qualifies Palatino Sans as sans serif but the German text talks about Grotesk A lifetime One possible reason why Hermann has always been able to catch up with technology and could adapt quite well to the transition from lead to computer was that originally he wanted to be an Elektroingenieur but calligraphy attracted him more Hermann was never stuck on characters only The book starts with a colorful full page illustration of flowers and small beetles Also in his early period he created a few Noten schriften The book shows many examples of hand writing and the grand finale is Zapfino which is avail able as a OpenType font with many complex features ENEE l EE Ero BETERE Vorlagen wurden bei dem Luftangriff auf das Buchh ndlerviertel in Leipzig am 4 Dezember 1943 vernichtet abedefghijklmnopgrsftuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ Bee i Greek Arab you name it he draws it Among his most well known fonts are Optima

14. article discusses the method that is used in MetaPost and luaTEX to integrate the string pool file into the program This method allows the redistribution of a single updated executable in place of both a program and a data file and this makes updating those programs easier on both the user and the developer me How a pool file is created The readers who regularly update their pdf TEX or MetaPost executables will probably be familiar with the concept of pool files already but I will explain the mechanics in some detail Programs written in the WEB language normally do not contain the strings inside the executable proper but in a separate file called the pool file The most important reason for the existence of this file is that back when Knuth was working on TEX and Metafont there was not yet a standardized way to handle strings inside the Pascal language so he had to invent his own solution for printing messages and warnings In order to illustrate what is in a pool file I will show you the required steps First here is a bit of WEB source from MetaPost if minx_val h gt maxx_val h then print 0 0 0 0 else begin ps_pair_out minx_val h miny_val h ps_pair_out maxx_val h maxy_val h end print_nl 4 Creator MetaPost print metapost_version print_nl CreationDate this excerpt is from one of the PostScript output routines Here there are still recognizable strings that are used as

18. function arguments as well as the symbolic value metapost_version that is actually a macro resolving to a string The processor tangle converts this input into a proper Pascal source file While doing so it resolves all of the many WEB macros that are present in the code metapost_version is one of those but also the constructs like minx_val h and maxx_val h It also removes the underscores from function names because traditional Pascal compilers did not allow _ to appear in identifiers What we are focusing on now is that it also collects all of the double quoted strings in the input It puts all of the unique multi character strings into an internal array and replaces the actual string in its output with the index number it has given the string inside that array Of course functions like print are written in such a way that they expect numbers as arguments instead of string values The Pascal output file looks like this if mem h 2 int gt mem h 4 int then print 1279 else begin pspairout mem h 2 int mem h 3 int pspairout mem h 4 int mem h 5 int end printnl 1281 print 256 printnl 1282 As you can see this file is clearly intended for a compiler only The complete lack of indentation makes it near impossible for a human to read the generated code but of course a Pascal compiler has no problem with it Nowadays creating an executable program from the WEB source file happens in a few extra
