Free reverse engineering software for linux

Software Engineering Environment (SEE) is frame for manufacturing information. It is implemented in sevlet and xml, and is used by the web-browser.
Software Engineering Environment (SEE) attempts to provide the information manufacturing platform for software development.
SEE is a free project, that is the author will provide all of its source code at the same time.
It runs in any servlet environment (The author merely verified in the Win and Linux environment), not using any special technique and needs no auxiliary program.
All of its data are saved in XML files, and need not database. (The future release will support the option of saving data, so that the user can select some free database, such as mysql, or commercial database to improve SEE speed.)
This means that the user can run SEE without any money. (Tomcat is a free servlet environment.)
User uses all SEE functions with the web-browser. So information sharing is very convenient.
SEE supports Simplified Chinese, Traditional Chinese, and English now.( It will support any language if someone will translate.) User can switch to interfaces in different language at any time when SEE is running. And user can add language translations which will work at once.
The main body of SEE is a frame for information manufacturing. All information included in it can be costumed dynamically and all changes will get into effect immediately. This means that the user can modify or add her/his own information structure as will at any time.
SEE provides various predefined selections for information attributes, which correspond various predefined information manufacturing patterns. The user can focus on the information description when costuming information definition, and the system will implement the functions automatically. This is the core of SEE. Most functions of SEE are in this model.
The default information definition of SEE is the result that the author understands what is the Software Engineering.
Although the target of SEE is helping for software development, actually, user can use it to design any type information, such as book registering, personnel lists, and financial reports etc.
The speed of SEE is not bad. Reading and writing 20000 records needs no more than 1 second. At present, the sorting speed is 9 seconds for 5000 records. (The testing platform is 1.8G CPU and 256M memory)
Enhancements:
- The data interface to prepare supporting databases.
- The databases are not supported in this release.
- A new interface style "Beautiful Flowers".
- These flowers are photoed in parks in this year by the author.
- The author likes the honeybee who holds a flower in its mouth very much. It is the first cartoon figure by the author. It will appear when you save wrong data. :)
- The function of "Personal Message".
- User can only query the messages sent by and sent to herself/himself. And user can only remove the messages sent to herself/himself.
- After a user read a message sent to her/him, SEE will mark it as "have_read" automatically.
- The number of new arrived messages will be shown in the interface.
- The data privileges management
- When user "Remove All" or "Modify All", the "base conditions" will be checked at first. That is user can only do what she/he can do.
- The Password fields values can not be visited, except when the user, who owns the "Import" privilege to current data, exports the data.
- All the data structures of ACL tables are changed! Their keywords become the "Title". This will permit user define better ACL.
- And the "condition" in the ACL tables are implemented completely. Now any "SEE conditions" is valid.
- Snapshot for image file
- When list the data, a snapshot will be shown for the image files type, which may end with jpg/jpeg/gif/png.
- Data sorting concerned with langauges.
- Thus when sorting data in Chinese, the result is Chinese result.
- General users can not visit the "User" table! Then they can not fill in many data!
- This is a fatal bug! This means all former releases can not be used actually!
- Now all ACL tables are redesigned.
- When a new user is added without password, SEE will add some password itself! Then this new user can never login!
- This is another fatal bug!
- In the last English release, which is 0.06, the ACL data are in Chinese!
- So the English users can not use SEE at all~~
- This is still a fatal bug!
- The "Risk Items" in the table "Deviation Handling" is wrong defined.
- This will cause an error information when user clicks the "Select" button.
- The values of Password fields can be visited when query or export.
- Although the values are meaningless encoded codes, they are still security thread.
- When some quota marks in the key values, pages will report errors and the function buttons, such as Modify and Remove, can not act!
- This is because quota is also an element of web page.
- When the interface language changes, the language in audit records changes too!
- This is not permitted. Language of all data is determined when SEE is installed and can not change with interface!

HTML::BBReverse is a Perl module to convert HTML to BBCode and back.

SYNOPSIS

use HTML::BBReverse

my $bbr = HTML::BBReverse->new();

# convert BBCode into HTML
my $html = $bbr->parse($bbcode);
# convert generated HTML back to BBCode
my $bbcode = $bbr->reverse($html);

HTML::BBReverse is a pure perl module for converting BBCode to HTML and is able to convert the generated HTML back to BBCode.

And why would you want to reverse the generated HTML? Well, when you have a nice dynamic website where you and/or visitors can post messages, and in those messages BBCode is used for markup. In normal cases, your website has a lot more pageviews than edits, and saving all those messages as HTML will be a lot faster than saving them as the original BBCode and parsing them to HTML for every visit.

So now all BBCode gets converted to HTML before it will be saved, but what if you want to edit a message? Just reverse the generated HTML back to BBCode, edit your message, and save it as HTML again.

OpenXava project is a framework to develop easily business applications with XML and Java.
OpenXava Eclipse Plugin provides a database reverse engineering utility for the OpenXava framework.
Its virtue resides in the fact that the heart of our applications is XML instead of Java.
Main features:
- Has been used during years to develop real applications.
- High productivity for developing business applications.
- Short learning curve and easy to use.
- Flexible enough to create sophisticated applications.
- Its possible to insert your own functionality in every place.
- Based in the concept of business component.
- Adapted to work with legacy database schemas.
- Generate a full J2EE application: including User Interface and model classes (with POJOs or EJBs)
- Supports WebSphere 6.0, 5.1 and 5.0, JBoss 4.0.x and 3.2.x using native EJB CMP2 EntityBeans.
- Supports any application server (Tomcat, JBoss, WebSphere, etc) using POJOs + Hibernate.
- Supports JSR-168: All OpenXava modules are standard portlets too.
- EJB3 JPA complete support: But still BETA until 2.1
- Its tested with the portals: JetSpeed 2, WebSphere Portal and Liferay.
- Easy integration of reports made with JasperReports.
- Some little support for aspects.
- Licensed under LGPL.
- The developer can use English or Spanish.
- All labels and messages are in English, Spanish, German, Indonesian, French and Catalan, with more coming.
Enhancements:
- This is the first version, and it includes support for connecting to a database to retrieve metadata from Eclipse, full customization for generated code, and support for advanced mapping features.

Digest::MD5::Reverse provides MD5 Reverse Lookup.
MD5 sums (see RFC 1321 - The MD5 Message-Digest Algorithm) are used as a one-way hash of data. Due to the nature of the formula used, it is impossible to reverse it.
This module provides functions to search several online MD5 hashes database and return the results (or return undefined if no match found).
We are not breaking security. We are however making it easier to lookup the source of a MD5 sum.
Version restrictions:
- It is very slow, because it will search each library until match found or all library search finished.
