PdfMasher is a tool to convert PDF files containing text into a ready-for-ebook set of HTML files. Most ebook readers support PDF files natively, but it's often a real pain to read those documents because you can't control the font size of the document and have to resort to the zooming feature instead. Another drawback of PDFs on ebook readers is that annotations are not supported. Unlike other tools that convert PDFs to ebooks, PdfMasher does not try to guess the role of each piece of text in the PDF, and instead asks the user about the role of each piece of text, and does so in an efficient manner.
iMan is a man page viewer for Mac OS X. It provides a native Aqua interface as an alternative to the use of the man program via the Terminal. A variety of useful features have been implemented, including multiple viewing windows, viewing of man pages as well as any man-format file on disk, support for apropos and whatis database searches, as well as in-page search with regular expressions, browser-style history (forward and back within any window), user-customizable font styles, and support for links to man pages in several forms (man:groff(1), man://groff/1, and man://1/groff are all supported). The reusable framework core can be embedded in other applications to provide man page handling functionality.
Pkviz is a tool for plotting and cycling through and animating a series of network packets captured by tcpdump. What makes it unique is that the packets’ structure is visualized, not any labels and not time itself. Pkviz takes each byte in a packet and plots it out end-to-end, left-to-right, from the first byte to the last. How high the dot gets plotted depends on the value of the byte: bytes with a value of 0 are at the bottom and those which are 255 (0xff) – the maximum value of a byte – get plotted at the top. This might not be interesting for one packet, but that changes when you start looking at thousands of packets. Pkviz can cycle through thousands of packets in the set so you can see what happened on the wire.
J2ObjC is a tool from Google that translates Java code to Objective-C for the iOS platform. It enables Java code to be part of an iOS build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as data access or application logic) in Java, which can then be shared by Web apps using GWT, Android apps, and iOS apps. J2ObjC supports most Java language and runtime features required by client-side application developers, including exceptions, inner and anonymous classes, generic types, threads, and reflection. JUnit test translation and execution are also supported.
