Free does size matter software for linux

Grey Matter is a CGI-based logging application suitable for a variety of purposes, mainly blogging. The project doesnt require a backend database and features a very flexible template system, as well as a karma and comment system.
Enhancements:
- Continuing code refactoring, with small admin UI enhancements such as paging on very long screens.
- Contains security enhancements and bugfixes as well.

Notes List is a simple and easy way to take Notes.

- Change SIZE (width and height)
- tun on/off the background image
- Auto save notes

Pysize is a graphical and console tool for exploring the size of directories. The project is written in Python, and requires Python ≥ 2.4 and pygtk ≥ 2.8 if you want to use the GUI.

Three user interfaces are available using the --ui command line option, the best available is chosen by default.

KeyCluster is a high availability (HA) system for mission critical applications running on Solaris (Sparc and x86), Linux, and AIX.
The project guarantees service availability and data access, switching services between machines in case of software or hardware failures in a matter of seconds.
Enhancements:
- The name to was changed KeyCluster and almost all of it was rewritten.
- Built-in support for DRBD and a KeySharing kit based on a shared USB SecureKey to store services status were added.

DB_eSession provides a class that securely stores PHP sessions in a MySQL database.
DB_eSession is a feature-packed PHP class that stores session data in a MySQL database rather than files. It is powerful, designed with security in mind, and is easy to utilize.
The code contains lots of comments, and it comes with full documentation and examples of how to use the class including a basic authentication login/logout process.
It includes member functions useful (to webmasters) for monitoring or viewing, deleting, and altering sessions validity for the case of locking one or more sessions upon detection of unauthorized use.
Main features:
- General features:
- Stores session data in a MySQL table using PHPs built-in session handler.
- Built-in handling of session expiration and cleanup.
- Supports the changes of session related configuration settings (inc. PHP5).
- Allows for normal or persistent MySQL database connections.
- Access to opened MySQL resource connection to use in your script.
- Accepts a passed database resource link to use as the DB connection.
- Supports session IDs between 12 and 32 characters long.
- Custom or changeable database, table and column names.
- An option to create new session IDs (you supply, class or PHP builds).
- Can initiate buffered output (using ob_start) within the class.
- A session_start() automatically initiated within the class.
- Can send Cache-Control: header output within the class (fixes IE6 bug).
- Ability to retrieve a specific sessions expiration date and time.
- Retrieve current session life setting in seconds or minutes.
- Retrieve a numeric total of the number of active and inactive sessions in table.
- Facility to make assignment and retrieval of session variables easier.
- Ability to create manual URIs and links that includes session name and ID.
- The ability to retrieve what the MySQL server version number is.
- An adequate form of encode/decode member functions are included and used automatically when libmcrypt is not installed.
- Security features:
- Standard user inactivity time-out handled automatically.
- Absolute user logoff time-out capability (session will be terminated no matter what after a number of designated minutes/seconds have elapsed).
- Ability to lock and unlock a particular session or all sessions. When a session is made locked it is immediately not available for use.
- User to session verification using IP address and browser information.
- Security level (code) clearance for each session/web page.
- Encrypt/decrypt as desired each session field.
- Encrypt/decrypt an extra session field to compare against original (to detect against possible tampering).
- Encrypt/decrypt the whole session data in the table (essentially obscuring session variable names in table). Can be used in combination with per session field encryption, resulting in double encryption security.
- A new encryption Initialization Vector is created every time values change.
- Ability to manually delete a particular session or all sessions.
- The users IP address and web browser is recorded as part of the session for tracing information.
- Other features:
- Support for multiple language error and warning messages.
- Support of a default language as well as current active language settings.
- Basic or detailed (with SQL syntax) error/warning reporting.
- Buffered error and warning messages.
- Option for class to stop execution or not upon encountering an error/warning. Class can display errors/warnings automatically or control in your script.
- Can select font color and size separately for error and warning messages.
- Code has lots of comments and formatted within 82 characters wide.
- Full documentation (only provided in English) is included.
- Code use examples provided, including a basic authentication (login/logout) process.
- SQL text file provided for creating the MySQL session table.

Diagnotep is an affliction search engine to help diagnose medical problems. Diagnotep project works in the mozilla browser, it might not work properly in other browsers. This is version 2007.1. To run the entire engine on your machine for a faster search, unzip the health archive into a folder and then open the file "health_diagnotep.html" with a browser.

The program is under the GPL license which basically welcomes you to copy or modify this and allows anyone else to copy or modify your version if you make it public. The text is under the GNU Free Documentation License which allows you to copy or modify this and allows anyone else to copy or modify your version if you make it public.

The program searches among the symptoms of a medical database, so the results will only be medical afflictions. There are about 1,800 afflictions in the database, so no matter how deep the search depth and how many symptoms are entered, there will be at most about 1,800 results. The links from the results page point to affliction pages which are either public domain government pages or GNU Free Documentation License pages.

The greatest advantage of the diagnotep search engine is that it searches only medical affliction pages, so the results are not cluttered with pages which are not about health. Another advantage is that the program searches only the symptom part of the affliction pages, so the results are not cluttered with unrelated medical pages. The greatest disadvantage of diagnotep is that it searches a medical database which is large, but incomplete; it does not include all the medical pages on the internet. Another disadvantage is that diagnotep has a size of about 200 kilobytes and so takes about 30 seconds to load on a 56k dialup modem.

Diagnotep development is ongoing and in the future it is hoped that there will be expanded treatment sections for common afflictions, that more afflictions will be added to the medical database and that the 200 kB size of the diagnotep script will be reduced for faster loading.

Come And Go Encryption provides an encryption program based off one-time pads.
Cum And Go Encryption is a very basic program to encrypt or decrypt a program using a variant of the one-time pad. This allows for almost uncrackable encryption.
Why is it still crackable? The program uses one relatively small key to XOR the contents of another file, encrypting it.
A one-time pad uses a very large key (about the same size as the file/data to encrypt) and is completely random. Still, the encryption is good enough to mask the identity of a program or document, or stop someone from accessing that document or program.
The origins of this program were an effort to stop a specific kind of movie and image from being viewed normally.
Installing is a breeze: simply run the program. Put it anywhere you like, it wont matter as long as you put the full path to the program to encrypt/decrypt.
Run the program to see a basic description of its use.
This program works very well in windows but was designed for use in Linux/UNIX. The stdout option allows for decryption to standard output, allowing one to pipe the programs decrypted data to another program.
This could be used to view an encrypted movie without having to write the whole movie to disk; the only problem with this is that on some Operating Systems pipes are slow and inefficient, especially with a high-bitrate movie. Steps will be taken to speed this up in the future.
Enhancements:
- Fix password use so the password is not shown in "encrypted" files
- Use an actual encryption method, and not a cheesy XOR
- Adapt CAG to use modules such as SHA, Crypt, MD5, and others
