2. But he was too smart and without skipping a beat he said yeah and how many lines of code did that take The answer is Zero There are many ways to write GUI apps on the Mac by supporting X11 by using Java by us ing third party libraries by using Carbon and by using Cocoa If your app is written in Co coa then it automatically supports the Retina display Otherwise not 10 NeXT at Apple 1997 2007 Many of you read the book about Steve Jobs by Walter Isaacson It is an interesting book but has been criticized for getting the story of NeXT and its role in Apple s second act wrong I agree and here s a short version of that story from my perspective Apple bought NeXT in December of 1996 a sale that was finalized in February of 1997 Each May or June Apple holds a Worldwide Devel oper Conference WWDC So in May of 1997 Apple had to give developers its strategy for us ing the NeXT operating system At the conference Apple said that old Macin tosh applications would continue to run in a sort of purgatory called the Blue Box but new ap plications needed to be written in Objective C using NeXT s class library then called Open Step Among commercial developers the an nouncement went over like a lead balloon and Apple got no significant endorsement at the con ference Apple s respected head of developer re lations Heidi Roizen quit a few months later calling the strategy crazy So in

Even though T X is able to write and process documents in hundreds of languages its own internal organization regarding use of language is next to nil On this talk we will show how the introduction of standards like ISO 639 ISO 15924 ISO 3166 1 and RFC 5646 are producing real cross pollination among projects like Babel Polyglossia BIBIATEX and CSL and driving the internationalization of TeX further TUG 2014 Michael Doob Using animations within ATRX documents TEX has always been in its heart a program for creating beautiful books As TEX matured markup was simplified using IAT X packages for creating beautiful tables of contents and indexes appeared and colour was added Graphics packages were also added allowed beautiful illustrations but the resulting output was in essence a book This era of progress is disappearing We now read novels on our smart phones and mathematical papers on our tablets The objects being viewed are less like traditional books and have potential to be much more exciting Fortunately TEX is flexible enough to adapt to the changing environment As a step supporting this change we survey the varied techniques available to create animations within LATEX documents David Farmer Converting structured IATRX to other formats I will describe a project which converts research papers and textbooks in mathematics from LATEX to HTML providing an alternative to online PDF documents This project spe

Retina Display or Preserving Window Locations when Quitting and I Hate Auto Save Back there five or six pages you mentioned crashes Why don t you talk about TeXShop crashes OK One problem with object oriented programming is that a program can create hundreds of dif ferent objects as it runs The program is sup posed to throw away objects after it is done with them if it doesn t then computer memory be comes clogged and the program becomes slug gish preliminary draft July 21 2014 11 58 TUGboat Volume 0 9999 No 0 Re Amberv reviewed on 18 Dec 2012 50 preliminary draft July 21 2014 11 58 913 This is a nice TeX editing environment but these days it is marred by Apple s hideous Auto Save feature It would be nice to have a version of this program that used the normal load save revert file management system Another great loss in recent history is the find and replace panel It now just uses Apple s bog standard panel which is okay for non coders but fairly worthless for anyone that needs to work around code spans So overall in its eagerness to adopt some of Apple s less enticing newer OS features it s kind of dropped behind the pack for me Version 3 11 Figure 11 A Review Objects can be passed around so just because one part of the program is done with an ob ject doesn t mean that it isn t used by someone else If an object is thrown away too soon the program will crash

13. processing the data in their instance variables Cocoa programs are object oriented To see how this works in practice consider the Cocoa object called NS View Each NSView cor responds to a rectangular portion of a particu lar window The view has an instance variable pointing to it s window a second instance vari able giving the coordinates of its rectangular re gion and so forth Among the methods defined for an NSView are drawRect which draws the view on the screen When a developer uses NSView the developer defines a subclass of the view with a name like myNSView This subclass has all the instance variables and methods of NSView plus other instance variables and methods added by the programmer But in addition it can override some of the original methods of NSView For instance the drawRect command in NSView doesn t draw anything but myNSView could override drawRect so it draws the logo of this conference In this situation we call NSView the Base Class defined in Cocoa and we call myNSView a subclass defined by the program mer The advantage of all this is that base classes usually come already connected up Cocoa calls drawRect when the window first appears when a covering window is moved out of the way when a dialog box goes away etc Apple once gave developers a teeshirt with the text Don t call us we ll call you The slogan means that the programmer s myNSView doesn t have to worry about

24. T X s Font Repertoire Michael Sharpe Garalde Family The first 150 years of the printing industry beginning with Gutenberg in 1450 bear a striking resemblance to the early years of the personal computer industry Both were intensely commercial enterprises though with some high toned gloss Bibles then scientific computing now However the real money driving the printers of the late 15th century was to a con siderable extent indulgences big money makers for the Church as well as printers As I learned from the fascinating books of Andrew Pettegree 2 3 some monasteries were ordering from printers and selling to sinners hundreds of thousands of generic indulgences as soon as the technology to do so be came available The closest modern analogue may be the claim that pornographic movies drove the rapid growth of VCR and later DVD players The Lutheran Revolt of the early 16th century against the excesses of the Church did not hurt print ers as they worked overtime to print the voluminous tracts generated by the religious conflict One must bear in mind that the first newspaper did not appear until 1605 Given the importance of printed media in that period it should not be surprising that much tal ent coalesced around the technology and the fonts developed during that brilliant advance are in my opinion some of the most appealing ever created They are referred to now as old style or Garalde in honor of Aldus M
