Lab Tick – Introducing Control. Have you ever been annoyed by your PowerBook’s (or MacBook Pro’s) backlit keyboard? You can not control it, you simply have to deal with the behaviour dictated by the ambient light sensor, which sometimes does not work really well. The idea of a backlit
keyboard is awesome, but the implementation in Mac OS X has its flaws. Lab Tick aims to fix them.
Neo Office An office suite for Mac osx which is based on openoffice.
OnyX is a multifunction utility for Mac OS X. It allows you to verify the Startup Disk and the structure of its System files, to run misc tasks of system maintenance, to configure the hidden parameters of the Finder, Dock and of some of Apple’s own applications, to delete caches, to remove a certain number of files and folders that may become cumbersome and more.
Quicksilver is a unified, extensible interface for working with applications, contacts, music, and other data. When opened, it will create a catalog of applications and some frequently used folders and documents. Activate it, and you can search for and open anything in its catalog instantly. The search is adaptive, so Quicksilver will recognize which items you are searching for based on previous experience. It also supports abbreviations, so you can type entire words, or just fragments of each. When not in use, Quicksilver vanishes, waiting for the next time you summon it.
Quicksilver’s greatest strength, however, is not search. Any item you are able to find, drag, or otherwise pull into its universe is endowed with many potential uses. Hitting takes you to the action field, where you can use the same adaptive search to select what you would like to do. Among other things, files can be emailed, copied, compressed. Text can be modified, transmitted between programs, or searched for on the web. Some actions even support an indirect object, so you can send an item to a person, move files to another folder, or open files with a specific application.
Quicksilver can be given the ability to understand the data inside of files, allowing you to work with data in new, faster ways. Plug-ins add both new items and new actions, allowing you to run scripts, send instant messages, dial phone numbers, look up words in a dictionary, queue up songs in iTunes party shuffle, and much, much more. Frequently used commands can be bound to triggers, giving you the ability to execute them immediately by hitting a hot key or using the mouse on a corner or edge of the screen.
TeXShop is a TeX editor for Mac OS X, written in Cocoa. Since pdf is a native file format on OS X, TeXShop uses “pdftex” and “pdflatex” rather than “tex” and “latex” to typeset in its default configuration; these programs in the standard TeX Live distribution of TeX produce pdf output instead of dvi output.
TeXShop uses TeX Live, a standard distribution of Tex programs maintained by the TeX Users Group (TUG) for Mac OS X, Windows, Linux, and various other Unix machines. The distribution includes tex, latex, dvips, tex fonts, cyrillic fonts, and virtually all other programs and supporting files commonly used in the TeX world. The most recent version of this distribution is maintained for the Mac by the MacTeX TeXnical Working Group of the TeX Users Group and available under the “Obtaining” tab.
The latest TeXShop release requires System 10.4 (Tiger), although System 10.5 (Leopard) is strongly recommended because it fixes several important bugs in Apple’s PDFKit code, extensively used in TeXShop. Users with systems 10.2 or 10.3 should use TeXShop 1.43, also available on this site. Users with systems 10.0 and 10.1 should use TeXShop 1.19, available here.
TeXShop is distributed under the GPL public license, and thus free.
