Xournal is an open source tool for annotating PDF files. It supports pen, mouse, and keyboard input. [1] It and the related Xournal++ are commonly used for adding annotations and electronic signatures to PDF files, especially on Linux desktops. [2]
Users can open PDF files and use Xournal to highlight in color, type text, and draw diagrams. Xournal uses the Poppler program library to render the PDF files.
Annotations can be saved in the program's .xoj file format without modifying the original PDF file. Users can export a separate annotated PDF. [3]
The related project Xournal++ uses the .xopp file extension. It started as a rewrite of Xournal in C++, but has since grown beyond the original. Xournal stopped adding new features in 2016, while Xournal++ remains under active development in 2024. Although Xournal++ is not formally considered the successor to Xournal, the original's author suggests users try Xournal++. [4] [5]
Free software, libre software, or libreware is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software regardless of how much is paid to obtain the program. Computer programs are deemed "free" if they give end-users ultimate control over the software and, subsequently, over their devices.
GnuCash is an accounting program that implements a double-entry bookkeeping system. It was initially aimed at developing capabilities similar to Intuit, Inc.'s Quicken application, but also has features for small business accounting. Recent development has been focused on adapting to modern desktop support-library requirements.
Gambas is the name of an object-oriented dialect of the BASIC programming language, as well as the integrated development environment that accompanies it. Designed to run on Linux and other Unix-like computer operating systems, its name is a recursive acronym for Gambas Almost Means Basic. Gambas is also the word for prawns in the Spanish, French, and Portuguese languages, from which the project's logos are derived.
Web annotation can refer to online annotations of web resources such as web pages or parts of them, or a set of W3C standards developed for this purpose. The term can also refer to the creations of annotations on the World Wide Web and it has been used in this sense for the annotation tool INCEpTION, formerly WebAnno. This is a general feature of several tools for annotation in natural language processing or in the philologies.
chroot is an operation on Unix and Unix-like operating systems that changes the apparent root directory for the current running process and its children. A program that is run in such a modified environment cannot name files outside the designated directory tree. The term "chroot" may refer to the chroot(2) system call or the chroot(8) wrapper program. The modified environment is called a chroot jail.
ClamAV (antivirus) is a free software, cross-platform antimalware toolkit able to detect many types of malware, including viruses. It was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, macOS, OpenVMS, OSF (Tru64), Solaris and Haiku. As of version 0.97.5, ClamAV builds and runs on Microsoft Windows. Both ClamAV and its updates are made available free of charge. One of its main uses is on mail servers as a server-side email virus scanner.
sudo is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. It originally stood for "superuser do", as that was all it did, and it is its most common usage; however, the official Sudo project page lists it as "su 'do' ". The current Linux manual pages for su define it as "substitute user", making the correct meaning of sudo "substitute user, do", because sudo can run a command as other users as well.
DTrace is a comprehensive dynamic tracing framework originally created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time. Originally developed for Solaris, it has since been released under the free Common Development and Distribution License (CDDL) in OpenSolaris and its descendant illumos, and has been ported to several other Unix-like systems.
Free and open-source software (FOSS) is software that is available under a license that grants the right to use, modify, and distribute the software, modified or not, to everyone free of charge. The public availability of the source code is, therefore, a necessary but not sufficient condition. FOSS is an inclusive umbrella term for free software and open-source software. FOSS is in contrast to proprietary software, where the software is under restrictive copyright or licensing and the source code is hidden from the users.
AppImage is an open-source format for distributing portable software on Linux. It aims to allow the installation of binary software independently of specific Linux distributions, a concept often referred to as upstream packaging. As a result, one AppImage can be installed and run across Ubuntu, Arch Linux, and Red Hat Enterprise Linux without needing to use different files. It aims to be a format that is self-contained, rootless, and independent of the underlying Linux distribution.
A portable application, sometimes also called standalone software, is a computer program designed to operate without changing other files or requiring other software to be installed. In this way, it can be easily added to, run, and removed from any compatible computer without setup or side-effects.
GNU Oleo is a discontinued lightweight free software spreadsheet originally designed as a text-based spreadsheet using the curses library. The last development version of Oleo, 1.99.16, was released in 2001.
Zotero is free and open-source reference management software to manage bibliographic data and related research materials, such as PDF and ePUB files. Features include web browser integration, online syncing, generation of in-text citations, footnotes, and bibliographies, integrated PDF, ePUB and HTML readers with annotation capabilities, and a note editor, as well as integration with the word processors Microsoft Word, LibreOffice Writer, and Google Docs. It was originally created at the Center for History and New Media at George Mason University and, as of 2021, is developed by the non-profit Corporation for Digital Scholarship.
A software repository, or repo for short, is a storage location for software packages. Often a table of contents is also stored, along with metadata. A software repository is typically managed by source or version control, or repository managers. Package managers allow automatically installing and updating repositories, sometimes called "packages".
Specials is a short Unicode block of characters allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 code points, five have been assigned since Unicode 3.0:
PDF-XChange Viewer is a freemium PDF reader for Microsoft Windows. It supports saving PDF forms (AcroForms) and importing or exporting form data in FDF/XFDF format. Since version 2.5, there has been partial support for XFA, and exporting form data in XML Data Package (XDP) or XML format. OCR support was also added in version 2.5.
Okular is a multiplatform document viewer developed by the KDE community and based on Qt and KDE Frameworks libraries. It is distributed as part of the KDE Applications bundle. Its origins are from KPDF and it replaces KPDF, KGhostView, KFax, KFaxview and KDVI in KDE 4. Its functionality can be embedded in other applications.
RPM Package Manager (RPM) is a free and open-source package management system. The name RPM refers to the .rpm file format and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base.
Sonic Visualiser is an application for viewing and analysing the contents of music audio files. It is a free software distributed under the GPL-2.0-or-later licence.
Foliate is a free e-book reading application for desktop Linux systems. The name refers to leaves, meaning "(getting) leafy" or "…-leaved".
