APK (file format)

Android Package Kit (APK) is the file format that software for Android is distributed in. It is an extension of the ZIP file format. An APK file contains bitcode for Android's Dalvik Virtual machine, resources used by the program (such as images and sounds), and sometimes native executable code, usually for the ARM processor.

The APL Programming Language Source Code

Thousands of programming languages were invented in the first 50 years of the age of computing. Many of them were similar, and many followed a traditional, evolutionary path from their predecessors. What eventually became APL was first a mathematical notation, not as a computer programming language.

An open letter to office suite users, just before the Euro-Office announcement - TDF Community Blog

Dear office suite users, In recent days you will have read various articles announcing the arrival of Euro-Office, which is being “marketed” as the first open-source office suite developed in Europe. We feel compelled — reluctantly, since open source should rest on transparency, not deception — to correct this claim. The first open-source office suite developed in Europe was OpenOffice.org in 2001, based on StarOffice’s source code, followed by LibreOffice from 2010. These are two genuine open-source office suites, built from source code that originated in Europe. They are not a freeware clone of MS Office whose code provenance is undisclosed, nor a product that has rebranded itself out of pure opportunism to ride today’s wave of Digital Sovereignty. It is worth remembering that many of those who champion Digital Sovereignty today were silent back in 2006, when the open ISO/IEC ODF standard — the pillar of Digital Sovereignty — was announced: not only did they not listen to us during all these years, but in some cases they greeted us with a condescending smile. If we can speak of Digital Sovereignty in Europe today, it is thanks to The Document Foundation and LibreOffice community members at large, who kept

Secure coding technique: Default behavior of Zip libraries can lead to Remote Code Execution - Blog

This week we are going to talk about the default behavior of Zip libraries. If you are an application developer, it is very likely that you have used this before. Most resources that are downloaded over the internet are in zip format, this makes sense; compressed data is smaller, so it downloads faster and consumes less bandwidth.

Practical Common Lisp

This page, and the pages it links to, contain text of the Common Lisp book Practical Common Lisp published by Apress These pages now contain the final text as it appears in the book. If you find errors in these pages, please send email to book@gigamonkeys.com. These pages will remain online in perpetuity—I hope they will serve as a useful introduction to Common Lisp for folks who are curious about Lisp but maybe not yet curious enough to shell out big bucks for a dead-tree book and a good Common Lisp tutorial for folks who want to get down to real coding right away. However, don't let that stop you from buying the printed version available from Apress at your favorite local or online bookseller. For the complete bookstore browsing experience, you can read the letter to the reader that appears on the back cover of the treeware edition of the book.
