Aciqra is a night sky simulator to show the sky and celestial objects. It uses the highly precise Aloac program to calculate highly accurate positions for planets, stars, comets, and everything else in the sky for thousands of years into the future. It can load a variety of catalogs and even custom ones with a bit of extension.
Bibfilex is software to create and manage archives of bibliographical items (books, articles, etc.) according to Biblatex structure and rules. It is far less advanced than other bibliographic managers like JabRef, and allows only a few customizations. Its strength is speed and lightness, especially when used with many items. It uses SQLite as a database. It can store the items according to each of the entry types described in the Biblatex manual (book, article, etc.), import the content of a file in Biblatex format (like a JabRef database, a Mendeley BibTex exported file, or a Google Books BibTex downloaded file), export data to a Biblatex file (like a JabRef database), locate an item just typing its author name, title, etc. filter the items by selecting a keyword in a list, filter the items according to three different conditions (or to manually modify the SQL statement of the filter to make it more suitable or complex) or according to the \cite commands contained within a Latex document, associate various attachments (files of every kind) with each item, activate autocompletion of data in each field with “Ctrl + Space”, automatically create unique BibTex keys according to a pattern defined by the user, and specify the fields (columns) shown in the grid view of the data. It is also possible to replace the \cite and \printbibliography commands in a Latex document with extended citations and bibliography, which are composed according to a user-defined pattern, to export the Latex file in other formats more easily.
Calligra is an integrated suite of applications that cover office, creative, and management needs. It offers applications on both desktop computers and mobile platforms like tablets and smartphones. OpenDocument Format (ODF) is used, making it compatible with OpenOffice.org, LibreOffice, and Microsoft Office. Calligra Suite contains the following applications: Calligra Words (word processor), Sheets (spreadsheets), Stage (presentations), Flow (diagrams and flowcharts), Kexi (visual database creator), Braindump (note taking), Plan (project management), Krita (drawing), and Karbon (vector graphics).
DAE Tools is cross-platform equation-oriented process modelling, simulation, and optimization software. Various types of processes (lumped or distributed, steady-state or dynamic) can be modelled and optimized. They may range from very simple to those which require complex operating procedures. Equations can be ordinary or discontinuous, where discontinuities are automatically handled by the framework. Model reports containing all information about a model can be exported in XML MathML format, automatically creating high-quality documentation. The simulation results can be visualized, plotted, and/or exported into various formats.
DataStatix manages data of every kind, creates statistics and graphs, and exports data easily to the R environment. Its features include user management (create, delete, modify password) within the software, different levels of user data access (administrator, standard, read-only), user-defined templates (models) of data, the ability to create new databases easily, importation and exportation of data in CSV format, and synchronization of existing data from a CSV file created with DataStatix.
Emaigos imports Google contacts and calendars into Emacs. Contacts are stored in a Big Brother Database (BBDB) file, which makes them usable with many Emacs email packages, like Gnus. Google calendars are stored as a single Org-mode file, so events may be viewed as a structured document and possibly shown within an Agenda view. With Emaigos, it's possible to use Google as a contacts and calendars manager, while having all the same data available within Emacs. The original Google contacts and calendars are not modified in any way by Emaigos. The name "Emaigos" is an acronym for "EMAcs Importer for GOogle Stuff".
