"Do you hate starting on a new project and having to try to figure out someone else's idea of a database? Or are you in QA and the developers expect you to understand all the relationships in their schema? If so then this tool's for you.

SchemaSpy is a Java-based tool that analyzes the metadata of a schema in a database and generates a visual representation of it in a browser-displayable format. It lets you click through the hierarchy of database tables via child and parent table relationships. The browsing through relationships can occur though HTML links and/or though the graphical representation of the relationships. It's also designed to help resolve the obtuse errors that a database sometimes gives related to failures due to constraints."

"MindScript is an OpenSource visualisation and programming software suite.
Mindscript is an environment where you can develop software in a graphical way. This is often described as a RAD-type of programming, and stands for Rapid Application Development.
It's also an environment where you can visualize complex algorithms, easily make changes to them, and test them immediately.
Mindscript is also a OS integrated runtime environment (like the Java Viritual Machine). Install Mindscript, and you can run mindscript programs (.msf files) that people has created else where. The mindscript programs are platform independent. A program developed at linux can be run at windows without a problem.
Mindscript is free for non-commecrial use. However, companies do need to get a license "

"Microsoft Research's Community Technology presents SNARF, the Social Network and Relationship Finder.
SNARF was built around the notion that social network information that is already available to the computer system can be usefully reflected to the user: a message from a manager might be seen differently than a message from a stranger, for example. SNARF applies this idea to email triage: handling the flow of messages when time is short and mail is long.
The SNARF UI is designed to provide a quick overview of unread mail, organized by its importance. The UI shows a series of different panes with unread mail in them; each pane shows a list of authors of messages. Clicking on a name shows all messages involving that person.
People use a variety of strategies to handle triage; there is no single "best" ordering of email messages to produce an optimal outcome.
SNARF gives the user the freedom to build their own ordering. Each person in their inbox is assigned a set of meta-information: "number of emails sent in the last month," for example. These metrics can, in turn, be combined to create an ordering across all contacts. For more information, check out the CEAS paper on SNARF."

"Introduction to Sed
How to use sed, a special editor for modifying files automatically. If you want to write a program to make changes in a file, sed is the tool to use.
There are a few programs that are the real workhorse in the Unix toolbox. These programs are simple to use for simple applications, yet have a rich set of commands for performing complex actions. Don't let the complex potential of a program keep you from making use of the simpler aspects. This chapter, like all of the rest, start with the simple concepts and introduces the advanced topics later on.
A note on comments. When I first wrote this, most versions of sed did not allow you to place comments inside the script. Lines starting with the '#' characters are comments. Newer versions of sed may support comments at the end of the line as well. "

The sed editor is among the most useful assets in the Linux sysadmin's toolbox,
so it pays to understand its applications thoroughly
One of the best things about the Linux operating system is that it is crammed full of utilities. There are so many different utilities, in fact, that it is next to impossible to know and understand all of them. One utility that can simplify life in key situations is sed. It is one of the most powerful tools in any administrator's toolkit and can prove itself invaluable in a crunch. "

"Meet Vanilla: a new kind of web forum
With Vanilla we wanted to break the mold created and followed by just about every other forum on the web. We sat down and thought about what we liked, and more importantly, what we didn't like about web forums. We wanted emphasis on the discussions rather than the statistics. We wanted to stop using MSN or AIM to send secret messages to other forum members; We wanted to be able to save the common searches. Basically, we wanted the thing to work for us instead of against us. Most importantly we wanted it to be free and we wanted it to run on just about every web server out there. So, Vanilla is a PHP / MySQL solution that is 100% open-source. You can take it and alter it and use it free of charge. The GPL is your friend.
Here are a few more of Vanilla's features...
Extensibility
A fully extensible solution, Vanilla comes loaded with extensions, and we're adding new ones all the time. If you are a programmer, you can create your own, too. If you're interested in getting involved and making some extensions, read the documentation and join our community forum.
Style
Vanilla has an awesome xhtml setup that allows you to create custom styles, or you can use some of the ones we've already created. If you're a CSS guru, read the documentation and see how to create and submit your own styles.
Internationalization
Vanilla also has a custom language component that allows you to run any language. If we don't have your language, you should do a translation! Find out how at Lussumo Documentation.
Much, much more...
There is still so much more that we haven't even touched the surface of. But the best part of Vanilla is that it's not cluttered with links and buttons you don't understand. Vanilla is clean and smooth. Simply put: Vanilla is a pleasure to use."

Das geniale Verschlüsselungstool TrueCrypt ist in der Version 4 erschienen. Nun gibt es auch endlich Unterstützung für Linux. Die OS X-Version dürfte auch nicht mehr lange auf sich warten lassen. Die Änderungen im Detail:

New features:

• TrueCrypt volumes can now be mounted on Linux. The Linux version of TrueCrypt is available at http://www.truecrypt.org/downloads.php

• It is now possible to write to outer volume without risking that a hidden volume within it will get damaged (overwritten):
  
  When mounting an outer volume, the user can now enter two passwords: One for the outer volume, and the other for a hidden volume within it, which he/she wants to protect. In this mode, TrueCrypt does not actually mount the hidden volume. It only decrypts its header and retrieves information about the size of the hidden volume (from the decrypted header). Then, the outer volume is mounted and any attempt to save data to the area of the hidden volume will be rejected by the driver (until the outer volume is dismounted). For further details, please see the section ‘Protection of Hidden Volumes against Damage’ in the documentation.

• Support for the x86-64 (64-bit) platform

• TrueCrypt now runs on Windows XP x64 Edition (64-bit) and Windows Server 2003 x64.

• Support for big-endian hardware platforms (PowerPC, SPARC, Motorola, etc.)

• Full support for keyfiles. Keyfiles provide protection against keystroke loggers and may strengthen protection against brute force attacks. Keyfile is a file whose content is combined with a password. Until correct keyfile is provided, no volume that uses the keyfile can be mounted. Any number of, and any kind of files (for example, .mp3, .jpg, .exe, .avi) may be used as TrueCrypt keyfiles. TrueCrypt never modifies the keyfile contents. Therefore, it is possible to use, for example, five files in your large mp3 collection as TrueCrypt keyfiles (and inspection of the files will not reveal that they are used as keyfiles). TrueCrypt can also generate a file with random content, which can be used as a keyfile. For more information on keyfiles, see the chapter Keyfiles in the documentation.

• Support for language packs (localizations). Language packs may be downloaded at: http://www.truecrypt.org/localizations.php

• Whirlpool hash algorithm added.
  
  The size of the output of this hash algorithm is 512 bits. It was designed by Vincent Rijmen (co-author of the AES encryption algorithm) and Paulo S. L. M. Barreto. The first version of Whirlpool was published in November 2000. The second version, now called Whirlpool-T, was selected for the NESSIE (“New European Schemes for Signatures, Integrity and Encryption") portfolio of cryptographic primitives (a project organized by the European Union, similar to the AES contest). TrueCrypt uses the third (final) version of Whirlpool, which was adopted by the International Organization for Standardization (ISO) and the IEC in the ISO/IEC 10118-3:2004 international standard.

• Auto-Dismount facility, which can be set to dismount a volume after no data has been written/read to/from it for specified number minutes. It can also be set to dismount all mounted TrueCrypt volumes when:
  - user logs off
  - entering power saving mode
  - screen saver is launched
  Auto-dismount can be configured and activated in the Preferences (select Settings -> Preferences)

• TrueCrypt settings are not saved to the Windows registry file. Instead, they are stored in XML files in the folder where application data are saved on the system (for example, in C:\Documents and Settings\YourUserName\Application Data\TrueCrypt). In traveller mode, the configuration XML files are saved to the folder from which you run the file TrueCrypt.exe.
  
  Note: When you install this version of TrueCrypt, all TrueCrypt settings that were stored by previous versions in the registry file will be automatically removed.

• Tray icon. Right-clicking the tray icon opens a popup menu with the most used functions. Left-clicking the tray icon opens the main TrueCrypt window and puts it into the foreground.

• Optionally, TrueCrypt can now continue running in the background after its main window is closed. This is referred to as TrueCrypt Background Task. When the main TrueCrypt window is closed, the TrueCrypt Background Task handles the following tasks/functions:
  1) Hot keys
  2) Auto-dismount
  3) Notifications (e.g., when damage to hidden volume is prevented)
  4) Tray icon
  For more information, see the chapter TrueCrypt Background Task in the documentation.

• When a mounted volume is right-clicked in the drive list (in the main TrueCrypt window), a context menu is opened. From this menu, the user can select functions such as ‘Repair Filesystem’ or ‘Check Filesystem’ (front-end to the ‘chkdsk’ tool).

• Containers stored on a locally mapped network drive can now be mounted.

• Container stored on a remote server can be mounted via UNC path (e.g., \\server\share\volume).

• Option to display password (typed in input field)

• ‘Favorite Volumes’ facility, which is useful if you often work with more than one TrueCrypt volume at a time and you need each of them to be mounted as the same drive letter every time. For more information, see the chapter ‘Main Program Window’, section ‘Program Menu’, subsection ‘Volumes -> Save Currently Mounted Volumes as Favorite’ in the documentation.

• Functions ‘Backup Volume Header’ and ‘Restore Volume Header’ added to the Tools menu. Both the standard volume header and the hidden volume header area are always backed up (copied to the backup file) even if there is no hidden volume within the volume (to preserve plausible deniability of hidden volumes).
  
  Note: If you do not have enough free space to backup all files, we highly recommend that you at least use this facility to backup the volume header, which contains the master key (size of the backup file will be 1024 bytes). If the volume header is damaged, the volume is, in most cases, impossible to mount.

• System-wide hot keys (which can be used, for example, to dismount all TrueCrypt volumes, etc.)

• Users can now set actions to perform upon log on to Windows. The actions can be any of the following:
  - Start TrueCrypt
  - Mount all device-hosted TrueCrypt volumes
  - Mount favorite volumes
  These actions can be enabled in the Preferences (select Settings -> Preferences).

• Title bar of the password prompt dialog window now displays path to volume being mounted

• When the 'Never save history' option is enabled, TrueCrypt clears the registry entries created by the Windows file selector for TrueCrypt. Therefore, the Windows file selector will not remember the path of the last mounted container after you exit TrueCrypt. Note that even when this option is enabled, the file selector will still remember the path, but only until you exit TrueCrypt.

• Set Header Key Derivation Algorithm' added to the Volumes menu. It allows the user to re-encrypt a volume header with a header key derived using a different PRF function (e.g., instead of HMAC-SHA-1 you could use HMAC-Whirlpool). Note: Volume header contains master encryption key with which volume is encrypted. Therefore, data stored on the volume will not be lost after this function is used.

• Number of bytes read/written from/to a volume since it was mounted is displayed in the Volume Properties window.

• Preserving container timestamps can now disabled in the Preferences (Settings -> Preferences).

• Command line usage:
  
  if ’/silent’ is specified, interaction with user (prompts, error messages, warnings, etc.) is suppressed.
  
  If '/m timestamp' is specified, volume/keyfile timestamps are not preserved.
  
  ’/keyfile’ may be used to specify a keyfile or a keyfile search path.
  
  ’/auto favorites’ may be used to mount favorite volumes.
  
  ’/auto’ is implicit if ’/quit’ and ’/volume’ are specified.
  
  If ’/q preferences’ is specified, TrueCrypt loads/saves settings.

• Auto-Mount Devices keeps prompting for a password until a volume is successfully mounted or until cancelled. Warning is displayed after each unsuccessful mount.

• If the Shift key is down when clicking 'Auto-Mount Devices' and if there are cached passwords, then password prompt will be bypassed (mounting will be attempted only with cached passwords).

• It is now possible to run multiple instances of the TrueCrypt application simultaneously.
  

Improvements:

• Mounting of fragmented file-hosted volumes (containers) takes significantly less time.

• New SHA-1 routines by Brian Gladman, which are approx. three times faster than the original ones (speeds up mounting).

• Enhancements to the random number generator:
  
  Hash function output is XORed into the pool (in E4M and the previous versions of TrueCrypt the values produced by a hash function replaced the original values in the pool).
  
  Input to hash function will always be the entire pool.
  
  Position of the pool cursor does not change when the FastPoll function is applied. This ensures that mouse coordinates are always evenly distributed in the pool (significant particularly when moving the mouse uninterruptedly).
  
  Event delta/absolute time will be added modulo 2 32 to the pool at the same position as the event data. (In the previous versions, event delta times were added separately modulo 2 32 to the pool. Delta times provide only a small amount of entropy, particularly when moving the mouse uninterruptedly.)
  
  For more information see the chapter Technical Details, section Random Number Generator in the documentation.
  
  Important: That we made these enhancements to the random number generator does NOT mean that volumes created using previous versions of TrueCrypt are insecure.

• File-hosted volumes are pre-allocated before they are formatted. Therefore, containers are created faster and less fragmented.

• When TrueCrypt re-encrypts a volume header (for example, when changing a password), the original volume header is first overwritten 35 times with random data to prevent adversaries from using techniques such as magnetic force microscopy to recover the overwritten header.

• Traveller disk can be created when TrueCrypt is running in traveller mode.

• TrueCrypt warns if automatic mounting of new volumes is disabled in Windows and informs the user how to enable this functionality.

• Other minor improvements

Bug fixes:

• Hidden volume password can now be changed on all types of removable media (e.g., all types of USB memory sticks).

• When changing a password and an error occurs during the creation of a new volume header, the header will not be written and the error will be reported.

• FAT file system created by TrueCrypt will have the same properties as FAT file system created by Windows.

• Drive list will be updated whenever drive letter assignments change.

• If an error occurs, TrueCrypt returns exit code 1, otherwise it returns 0 (command line usage).

• Password specified on command line (/p ) now works with ‘/a devices’ as well (command line usage).

• Other minor bug fixes

Miscellaneous:

• Size of the random number generator pool increased from 256 to 320 bytes

• The command line option ‘/quiet’ has been renamed to ‘/quit’

• The Serpent routines written in assembly have been replaced with routines written in C, so that the whole source code is more portable.

• Released under TrueCrypt License 2.0
