JLicense is a Java utility library for validating and creating license keys. It includes a simple GUI tool for creating the license file and a LicenseManager (which should be embeded inside your Java software) for validating the license.

You can also write your own class, such as a Servlet, to create the license file more dynamically based on user input data.

JLicense is feature based, and you can validate the license based on the features. For example, you can add features like IP address, MAC address, user number etc.

RAR 3.80 / 3.90 Beta 4 is a well-known and extremely powerful archive utility for everyone. It allows you to manage and control archive files. Console RAR supports archives only in RAR format, the names of which usually have a ".rar" extension. ZIP and other formats are not supported. Windows users may install GUI RAR version - WinRAR, which is able to process much more archive types.
The trial version has a 40-day usage limit.

Major Features:

1. RAR introduces an original compression algorithm. It allows higher compression ratios than other PC archiving tools, especially on executable files, object libraries, large text files, etc.
2. RAR offers an optional compression algorithm highly optimized for multimedia data.
3. RAR provides functionality for creating a solid archive, which can raise the compression ratio by 10% 50% over more common methods, particularly when packing large numbers of small files.
4. RAR offers the ability to create and change SFX archives using default and external SFX modules.
5. RAR offers the ability to create a multi-volume archive as SFX.
6. RAR offers a number of service functions, such as setting a password, adding archive and file comments. Even physically damaged archives may be repaired and an archive may be locked to prevent further changes. Authenticity information may be added for additional security and RAR will store information on the last update and name of the archive.

Enhancements:

• WinRAR version for Windows x64 is available. If you use Windows x64, it is strongly recommended to install 64 bit WinRAR version. It provides a higher performance and better shell integration than 32 bit version.
• RAR compression speed is improved for multi-core and multi-CPU systems. This improvement is most noticeable in Windows Vista and Windows 7 operating systems.
• "Remove duplicate folders from extraction path" option in "Settings/Compression" dialog is replaced by more universal "Remove redundant folders from extraction path" option. This option will eliminate redundant archive name based folders from extraction path if you unpack an archive with "Extract to DestName" context menu command and if archive root folder contains only one folder and no files.
• Changes in "Extraction path and options" dialog:
• • "New folder" button creates a new subfolder in currently selected folder;
  • F2 key renames a selected folder in the folders tree;
  • F5 key updated the tree pane contents;
  • Del key removes a selected folder in the folders tree.
  • You can enable "Show seconds" option in "Settings/File list" dialog if you wish to see seconds in file dates in file list in WinRAR shell.
  • "Where to check for SFX archives" options group in "Settings/Integration/Context menus items" dialog lets you to control processing of SFX archives in context menus. For example, if you frequently right click ".exe" files on slow network disks, you can turn off "Network disks" options to minimize the delay before displaying the context menu.
  • If you sort files by name in the file list in WinRAR shell, WinRAR will use the new logical file name sorting, same as in Windows Explorer, considering digits in file names by their numerical value. So files will be sorted as 1.txt, 2.txt, 10.txt instead of previous 1.txt, 10.txt, 2.txt. This new sort behavior is available in Windows XP Service Pack 2 and newer.
  • Ctrl+W key combination can be used to close the main WinRAR window also as WinRAR viewer windows. "View as Windows text" shortcut in WinRAR viewer changed from Ctrl+W to Ctrl+I.
  • New command line switch -rdisables recursion completely. So rar a -rarc dirname command will add only the empty dirname folder and ignore its contents. By default, if dirname does not include wildcards, RAR adds its contents even if -r switch is not specified.
  • If used when extracting, the new command line switch -ai forces RAR to ignore file attributes. When using this switch, extracted files will always have attributes assigned by operating system to a newly created file by default.
  • If output file name is not specified in "cw" command, console RAR will send comment data to stdout.
  • When compressing stdin data with -si[name] switch, RAR sets modification time of archived entry to current system time. Previous RAR versions did not fill this field, resulting in meaningless modification time for stdin.
  • Message displayed when you place the mouse cursor on WinRAR tray icon includes the archive name now. Previously only time left and total percent were displayed for archiving operations.
• Bugs fixed:
• • WinRAR could fail to open tar or tar.gz archive if such archive contained a file larger than 8 GB;
  • WinRAR context menu did not work properly in Windows 7 beta if icons in context menus were enabled and user clicked a file inside of Windows 7 Library folder;
  • previous WinRAR versions failed to rename files having 5 or more continuous spaces in the name. WinRAR shell does not display such spaces for safety reasons, because they can hide an actual file extension. But this security measure prevented the rename command to work properly.

Red Hat Enterprise Linux v.4, released in February 2005, provides significant technology enhancements over the v.3 release. Areas of specific development include improvements in security capabilities, increased server performance and scalability, and enhanced desktop capabilities?all while ensuring a high level of compatibility with prior releases.
Red Hat Enterprise Linux supports a wide range hardware and software applications, and is the worlds leading enterprise-focused Linux environment.
The following section outlines a few of the major new features in Red Hat Enterprise Linux v.4:
Linux 2.6 kernel infrastructure
Red Hat Enterprise Linux v.4 provides the most stable and robust commercial product based on the Linux communitys 2.6.9 kernel. Open source projects such as Fedora provided an environment for the Linux 2.6 kernel to mature significantly during 2004.
As a result, the Red Hat Enterprise Linux v.4 kernel offers numerous improvements over earlier kernels, including many enhanced algorithms and features:
- Generic logical CPU scheduler: Handles multi-core and hyperthreaded CPUs.
- Object-based Reverse Mapping VM: Improved performance in memory constrained systems.
- Read Copy Update: SMP algorithm optimization for operating system data structures.
- Multiple I/O schedulers: Selectable based on the application environment.
- Enhanced SMP & NUMA support: Improved performance and scalability for large servers.
- Network interrupt mitigation (NAPI): Improved performance for heavy network loads.
Improved storage and file system capabilities
Numerous enhancements have been incorporated into Red Hat Enterprise Linux v.4 that improve the scalability and performance of the data storage subsystems, including:
- Ext3 performance: Block Reservations and Hash Tree Directories improve the performance of read/write I/O and directory scanning operations.
- Ext3 scalability: Dynamic file system expansion and file system sizes up to 8TB are now supported.
- Logical Volume Management: A comprehensive update to the LVM provides new features such as read/write snapshots and transactional metadata updates, along with a flexible new management GUI. Mirroring and enhanced multipathing are scheduled for delivery by mid 2005.
- Scalability: Enhanced storage LUN management makes it possible to configure much larger storage subsystems.
- Automounting: The inclusion of AutoFSv4 provides sophisticated device access control, supporting features such as browsable mounts and replicated servers.
- Cost reduction: Support for Serial ATA disk storage provides increased performance, higher densities, and reduced cost per megabyte over traditional IDE devices.
New security capabilities
Provision of sophisticated security capabilities has been a specific development focus of the Red Hat Enterprise Linux v.4 release. New features:
- Mandatory Access Control: Security Enhanced Linux (SELinux) provides a MAC infrastructure that complements the existing Discretionary Access Control security features provided by the standard Linux environment. In a MAC-based environment, application capabilities and privileges are set by predefined policies and enforced by the kernel. This prevents errant applications from compromising system security.
- Memory management enhancements: Several features, including Exec Shield and Position Independent Executables, combine to prevent applications from being exploited by attacks such as buffer overflows.
- Compile and runtime consistency checking: New buffer validation techniques in the GCC compiler and Glibc library greatly reduce the risk of faulty applications being compromised.
Improved desktop capabilities
Significant emphasis has been placed on providing a feature-rich, easy-to-use, desktop environment for all Red Hat Enterprise Linux family members (including Red Hat Desktop). A brief summary of new features:
- Personal productivity: Advanced user capabilities are provided by the OpenOffice.org productivity suite, the Firefox web browser and Evolution email client
- Plug-and-play device support: Easy handling of devices such as USB disks and digital cameras (as well as photo management applications such as gThumb)
- Multimedia: Applications for audio, video, and streaming content such as RhythmBox, HelixPlayer, Totem, and SoundJuicer
- User environment: GNOME 2.8 provides numerous enhancements for a more consistent graphical look and feel. Comprehensive management tools (e.g. printer and network management and VNC-based application session sharing) and utilities (e.g. Gaim instant messaging, and GIMP image processing) combine to provide a complete and highly functional user experience.
- Interoperability: Technologies that allow user login authentication with Microsoft Active Directory, NTLM authentication for web-based applications, Evolution mail client access to Windows Exchange Servers
- IIIMF: The Internet/Intranet Input Method framework provides the next-generation multilingual Unicode input method framework. It offers many features, such as full Unicode support and the ability to run multiple concurrent language engines.
Miscellaneous features
As a major new release, almost every aspect of Red Hat Enterprise Linux has been enhanced. Some of the more important improvements:
- Compatibility with prior releases: Red Hat Enterprise Linux v.4 includes compatibility libraries that enable most v.3 and v.2.1 applications to continue to run without modification.
- Languages: Focused on international standards, such as OpenI18N and GB18030, Red Hat Enterprise Linux has documentation and software available in 15 languages: English, Japanese, German, Brazilian Portuguese, Korean, Italian, French, Simplified Chinese, Traditional Chinese, Spanish, Devnagari, Bangla, Punjabi, Tamil, Gujarati.
- Auditing: In an update planned for mid-2005, a new auditing facility will be available that provides an open, bidirectional socket interface that can be used by auditing applications. It provides comprehensive auditing capabilities for SELinux and standard Linux events.
- File serving: Provision of NFSv4 provides features such improved security, operation coalescing and integrated file locking, while Samba provides easy access to Microsoft Windows printers and file shares.
- Software development: The latest GCC 3.4 compiler toolchain, and a technology preview of the forthcoming GCC 4.0 toolchain, are provided. These offer standards-compliant C/C++ and Fortran 95 development environments.
- Advanced configuration and power interface: Support for the ACPI standard enables a wide range of power management capabilities (battery monitoring, automated power down, suspend), and provides a foundation for increasingly sophisticated features in the future.
- Extras: Optional software is provided on the Red Hat Enterprise Linux Extras CD and Red Hat Network channel. This includes features such as additional desktop applications (e.g. Adobe Reader, Macromedia Flash), Java environments, and printroom-quality Agfa/Monotype fonts.

PureBasic is a new "high level" programming language based on established BASIC rules. PureBasic is similar to any other BASIC compiler you may have used, whether for the Amiga or PC. Learning PureBasic is very easy! PureBasic has been created for the beginner and expert alike. Compilation time is really fast. We have put a lot of effort into its realization to produce a fast, reliable and system friendly language.
The syntax is simple but the possibilities are endless with PureBasics advanced features, such as pointers, structures, procedures, dynamically linked lists and much more. The experienced coder will have no problem in gaining access to any of the legal OS structures or API objects.
PureBasic is a portable programming language which currently works on AmigaOS (680x0 and PowerPC), Linux, MacOS X (PowerPC) and Windows computer systems. This means that the same code can be compiled natively the three systems and still use the full power of each. There are no bottlenecks like a virtual machine or a code translator; the generated code produces highly optimized executables regardless of the OS on which it is compiled. The external libraries are mainly written in hand optimized assembler, which produces very fast commands, often much faster than the C/C++ equivalent.
