Free to correct software for linux

jSpellCorrect project is a simple statistical spelling corrector.
At moment I dont think there is much documentation necessary. Just download the JAR File and use this code to get started:
import org.gauner.jSpellCorrect.ToySpellingCorrector;
ToySpellingCorrector sc = new ToySpellingCorrector();
// train some data from a text file
sc.trainFile("/tmp/big.txt");
// train a single word
sc.trainSingle("some word");
// get the best suggestion
System.out.println(sc.correct("Cads"));
System.out.println(sc.correct("Dok"));
System.out.println(sc.correct("Speling"));
JavaDoc will be provided later.
Enhancements:
- A restriction on the size of the input files was removed.
- Memory consumption was reduced.

Cobertura is a free Java tool that calculates the percentage of code accessed by tests.Cobertura project can be used to identify which parts of your Java program are lacking test coverage. It is based on jcoverage.
Main features:
- Can be executed from ant or from the command line.
- Instruments Java bytecode after it has been compiled.
- Can generate reports in HTML or XML.
- Shows percent of lines coveraged and branches coveraged for each class, package, and for the overall project.
- Shows the McCabe cyclomatic code complexity of each class, and the average cyclomatic code complexity for each package, and for the overall product.
- Can sort HTML results by class name, percent of lines covered, percent of branches covered, etc. And can sort in ascending or decending order.
Enhancements:
- Much improved branch coverage. Information on whether the true as well as the false of an if statement is collected. Also, information on the branches of a switch statement (including the default) is collected. (Jiri Mares)
- Assume Java source files are saved as UTF-8 instead of the computers default encoding.
- Write all HTML and XML reports in UTF-8 instead of the computers default encoding (Naoki Iwami).
- Fix a bug where the Cobertura ant tasks would not work correctly in Microsoft Windows when Cobertura was installed on a different drive than the drive from which youre running ant (Srivathsan Varadarajan).
- Added a "maxmemory" attribute to the instrument, merge and report ant tasks (Matt Cordes).
- Improve support for Maven and similar environments where control over system properties is difficult such as app servers, IoC containers, IDEs, etc. Setting the datafile location is difficult in these environments. To correct this, a cobertura.properties file located in the classpath is used to properly set the net.sourceforge.cobertura.datafile property. (Joakim Erdfelt)

SQuirreL SQL Client is a graphical Java program that will allow you to view the structure of a JDBC compliant database, browse the data in tables, issue SQL commands etc. The minimum version of Java supported is 1.4.x. We recommend 1.5.x. See the Old Versions page for versions of SQuirreL that will work with older versions of Java.

SQuirreLs functionality can be extended through the use of plugins. A short introduction can be found here. To see the change history (including changes not yet released) click here.

Susan Cline graciously took the time to document the steps she followed to setup an Apache Derby database from scratch and use the SQuirreL SQL Client to explore it.
Quite some time ago Kulvir Singh Bhogal wrote a great tutorial on SQuirreL and published it at the IBM developerWorks site. He has kindly allowed us to mirror it locally. The tutorial is not really up to date but especially for doing the first steps it is still of help.

SQuirrel was originally released under the GNU General Public License. Since version 1.1beta2 it has been released under the GNU Lesser General Public License.

Whats New in This Release:

1716859 Cant see data in content tab or row count tab (MS SQLServer databases
with a dash ("-") in their name would cause the content tab or row count
tabs to render no data.

1714476: (DB copy uses wrong case for table names) The copy operation would
sometimes fail to select records from the source table. Since the
case for the source table is always known to be correct, the plugin
no longer erroneously attempts to correct the case.

1700093: Formatter fails for insert script with multiple subselects

Refactoring Plugin: SQL-Server needs eol between GO and statement.

Fixed bug which appeared while editing tables in PostgreSQL 8.1. If the table
was created without an OID column, the last column would not be editable.

Fix for issue where dates arent correctly displayed or updated when using
treat date as timestamp pref in the SQl Editor result panel.

Use the last directory that a file was imported from when importing additional
files for binary fields.

1699294: Squirrel imports BLOB, but does not update data

Oracle Plugin: Handle slashes when they are used as statement separators.

137984 (Bug in alias delete) The problem was that notifications were being
sent to the alias drop-down that the item was being deleted which trigger an
update and new selection forcing the connect to alias window to be launched.
Now, the alias drop down is disabled while the update is happening and enabled
immediately afterward.

Clorox is shared memory for AJAX applications. Clorox provides data structures that look exactly like ordinary JavaScript objects but that actually make AJAX RPC calls behind the scenes to fetch data.
Since many web applications can be thought of as viewers over structured data (grids of map cells, arrays of email messages, etc), and RPCs and callback functions are a pain, this abstraction makes writing applications much easier. Additionally, Clorox makes it simple to define data caching and prefetching policies to boost performance.
No new languages: Clorox applications are 100% JavaScript, and they play well with other toolkits.
Clorox is a new way of writing highly-interactive web applications. Its based on a single observation: that many web applications serve as viewers over structured data. Email clients display lists of messages. Mapping applications display grids of map cells. Search auto-complete applications display nodes in a trie containing completion strings. Today, such applications are often written using AJAX. Clorox argues that we can make these applications both higher performance and easier to write by exploiting the underlying logical structure of their data, a structure which is ignored by AJAX. (Note that the logical structure of the data is entirely separate from their physical representation on the server.)
In place of the asynchronous, RPC-based abstraction furnished by AJAX, Clorox provides the illusion of synchronously-accessed data structures shared between the web browser and web server, which is to say, it provides a shared memory abstraction. These data structures look exactly like ordinary JavaScript objects on the client side, allowing programmers to focus on what they do best (writing compelling web applications) without worrying about data locality, message reordering, callback functions, or data prefetching. Additionally, to free programmers from concerns over locking, Clorox allows multiple operations on these data structures to be grouped into atomic actions.
Clorox applications are 100% JavaScript: application programmers write JavaScript code which is processed by the Clorox compiler into more JavaScript. Clorox applications can thus run on any modern web browser without the need for special plugins, and your code will never be locked up in some proprietary format.
We think the best way to learn to use a new piece of software is by playing around with it, so the rest of this document will explain how to build a sample application using the Clorox system.
Enhancements:
- A small bug was fixed to correct a problem with dim() methods.
- The homepage URL was updated.

RPhoto is a small software aiming at the easy handling of digital cameras photos. (RPhoto is the next generation of IMPhoto).
RPhotos origin resides in the lack of a simple software capable of cropping photos with a constant ratio, to avoid white borders when printing.
RPhoto is distributed under the GPL licence. It allows you to use and distribute freely this software, within the respect of the GPL licence.
Main features:
- Crop images with a constant width / height ratio (by example 4:3 for numeric photos)
- Rotate / Flip photos
- Lossless crop / rotate / flip operations.
- Available under Linux and Windows.
Enhancements:
- This release adds the ability to correct a bad inclination of a picture by drawing a vertical or horizontal line, the modification of comments, Exif tags, undo last operations, and a few bugfixes.

C_COUNT counts C-language source statements, and summarizes statistics about
the relative amount of commentary, whitespace, etc.
It provides options to extend its usefulness, accommodating C-preprocessor
definitions that would confuse a simpler line-counter, and for displaying
non-graphic characters, etc.
C_COUNT project runs on a variety of UNIX systems, VMS and MSDOS.
Enhancements:
- correct bookkeeping for unterminated blocks (report by Lester Ingber).

CLNoFault is a tool to protect your files or plain text. Using XOR encryption, it can quickly encrypt data using either a username and a password of your choice, or an external file that will serve as a key.

Encrypted files cant be recovered in any way besides re-encrypting them with CLNoFault with the correct user/pass combination or keyfile.

CLNoFault is the console-based interface for the NoFault library (like KNoFault for KDE), so it is useful in scripts.

LaTrine project is a language vocabulary drill.

LaTrine is a curses-based LAnguage TRaINEr. It takes a dictionary and asks you for a word or a phrase, and you try to give the correct answer.

The direction is configurable. The selection of the words or phrases depends on how often you dont know the correct translation.

It can be used with the Free Dictionaries Project, which provides dictionaries for about 50 language combinations.
