UI Application for NoteTaking and Sketching - Xournal

Xournal is an application for notetaking, sketching, keeping a journal using a stylus. It is free software (GNU GPL) and runs on Linux (recent distributions) and other GTK+/Gnome platforms. It is similar to Microsoft Windows Journal or to other alternatives such as Jarnal and Gournal.

Xournal supports annotation of PDF files. Xournal uses the Poppler library to render PDF documents. The documents then become immutable background images. Annotation can then proceed using any of Xournal's standard tools: Pen, eraser, text, and highlighter.

Xournal Features:
* gettext internationalization
* Catalan translation, French translation
* use poppler instead of pdftoppm to render PDF backgrounds
* various improvements to UI and to key bindings
* use gtk-print instead of libgnomeprint for printing
* custom color chooser
* option to have tablet buttons toggle the mapping rather than draw
* paper color chooser

How to Install / Configure PostgreSQL Under Ubuntu Linux

07:30 No comments

PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) available for many platforms including Linux, FreeBSD, Solaris, MS Windows and Mac OS X. It is released under the PostgreSQL License, which is an MIT-style license, and is thus free and open source software. PostgreSQL is developed by the PostgreSQL Global Development Group, consisting of a handful of community volunteers employed and supervised by companies such as Red Hat.

It implements the majority of the SQL:2008 standard, is ACID-compliant, is fully transactional (including all DDL statements), has extensible data types, operators, and indexes, and has a large number of extensions written by third parties.

PostgreSQL Installation:
Open the terminal and type following command to install postgresql

sudo apt-get install postgresql

Personal Full Text Search UI Application - Recoll

07:30 No comments

Recoll is a full text search application. Full text search applications let you find your data by content rather than by external attributes (like a file name). More specifically, they will let you specify words (terms) that should or should not appear in the text you are looking for, and return a list of matching documents, ordered so that the most relevant documents will appear first.

You do not need to remember in what file or email message you stored a given piece of information. You just ask for related terms, and Recoll will return a list of documents where those terms are prominent, in a similar way to Internet search engines.

Recoll uses the Xapian information retrieval library as its storage and retrieval engine. Xapian is a very mature package using a sophisticated probabilistic ranking model. Recoll provides the mechanisms and interface to get data into and out of the system.
