dos trial software / shareware for linux

Dont give away sensitive information, valuable corporate trade secrets, business plans, personal files and letters, or traces of Internet or newsgroup activity with the old computers that you or your company resells, donates, reassigns to different departments or removes from operation.
Deleting all the files, formatting the hard disk or using the FDISK utility is not enough to stop people that will have access to the computer in the future to restore information using basic recovery programs.
East-Tec DiskSanitizer however removes all traces of data and software from the computer hard disk, by overwriting and destroying beyond recovery every sector and every bit of information.
Data is removed according with U.S. Department of Defense standards or custom user security levels. East-Tec DiskSanitizer can be operated from a floppy disk to sanitize any drive from the computer, regardless of the file system or the operating system.
After selecting the drives to sanitize and the security level, the product is ready to perform its job.
Powerful verification capabilities and full user control during the sanitizing process can provide the utmost assurance that all data has been completely removed beyond recovery. At the end of the sanitize process the product can generate a proof of correct data disposal by printing a sanitizing report or by saving it for permanent records
Main features:
- The data on drives formatted with East-Tec Sanitizer 2005 is destroyed beyond recovery using advanced wiping techniques that can stop both software and hardware tools from recovering any data.
- Meets and exceeds the U.S. Department of Defense standards for the permanent erasure of digital information.
- Works with both IDE/ATA and SCSI disk drives
- The ability to sanitize any floppy or hard disks connected to the computer, or any independent partition from a hard drive without affecting other partitions, regardless of the file system and the operating system that resides on each drive (works with FAT12, FAT16, FAT32, NTFS, DOS, Windows 3.x, Windows 95, Windows 98, Windows NT, Windows 2000, Windows XP, Unix, etc.).
- Powerful verification capabilities that give the user the utmost assurance that all data has been completely removed from disk.
- Very fast wiping speeds by using direct memory access (DMA/UDMA mode) for IDE/ATA drives (where support for this mode is available)
- The ability of wiping data on several machines simultaneously by installing Sanitizer on bootable floppy, CD or DVD disks.
- The ability to maintain detailed logs of all sanitizing operations, that can be printed and saved for permanent records.
- Overall progress, average speed and estimated time indicators are available.
- Mouse support.
Advanced Features:
- Powerful command-line parameter options that allow advanced users to run the program from the command prompt, with no user interface (if desired) and create different wiping scenarios.
- Sanitizing BIOS Free feature that allows users to address the full hard disk capacity even if, on some old machines, BIOS does not support large hard drives.
- The ability to develop and use your own data-destroying algorithms, that perfectly suits your security needs.
- The ability to generate random data streams using ISAAC Pseudo-Random Number Generating algorithm.

Euphoria is simple, flexible, and easy to learn. The project outperforms all popular interpreted languages. Complete Reference Manual included. Lots of free example programs with full source. Makes .EXE files.
Theres also a Euphoria To C Translator that gives really high speed. An easy-to-use database system is also included. The Web site has over 1200 contributed Euphoria programs with source.
Main features:
- Euphoria programs run on Windows, DOS, Linux, and FreeBSD.
- The language is flexible, powerful, and easy to learn.
- There is no waiting for compiles and links - just edit and run.
- You can create and distribute a royalty-free, stand-alone .exe file.
- Dynamic storage allocation is fundamental to Euphoria. Variables grow or shrink in size without the programmer having to worry about allocating and freeing chunks of memory. Elements of an array (Euphoria sequence) can be a dynamic mixture of different types and sizes of data.
- Euphoria provides extensive run-time error checking for: out-of-bounds subscripts, uninitialized variables, bad parameter values for library routines, illegal value assigned to a variable, and many more. If something goes wrong youll get a full error message, with a call traceback and a listing of variable values. With other languages youll typically get protection faults with useless dumps of machine registers and addresses.
- The Euphoria interpreter is more than 30 times faster than either Perl or Python, and its considerably faster than all other interpreted languages, according to the "Great Computer Language Shootout" benchmark (see demobenchbench.doc).
- If that isnt enough, theres a Euphoria To C Translator that can translate any Euphoria program to C, and boost your speed even more. Why waste time debugging hand-coded C/C++? You can easily develop a Euphoria program, and then generate the C code.
- Euphoria programs are not constrained by any 640K memory restrictions for which MS-DOS is infamous. All versions of Euphoria let you use all the memory on your system, and if that isnt enough, a swap file on disk will provide additional virtual memory.
- An integrated, easy-to-use, full-screen source-level debugger/tracer is included.
- Both an execution-count profiler, and a time profiler are available.
- There is a large and rapidly growing collection of excellent 3rd party programs and libraries, most with full source code.
- RDS has developed an extremely flexible database system (EDS) that is portable across all Euphoria platforms.
- The WIN32 implementation of Euphoria can access any WIN32 API routine, as well as C or Euphoria routines in .DLL files. A team of people has developed a Windows GUI library (Win32Lib), complete with a powerful Interactive Development Environment. You can design a user interface graphically, specify the Euphoria statements to be executed when someone clicks, and the IDE will create a complete Euphoria program for you. There are Windows Euphoria libraries for Internet access, 3-D games, and many other application areas.
- The DOS32 implementation of Euphoria on MS-DOS contains a built-in graphics library. If necessary, you can access DOS software interrupts. You can call machine-code routines. You can even set up your own hardware interrupt handlers. Many high-speed action games, complete with Sound Blaster sound effects, have been developed 100% in Euphoria, without the need for any machine code.
- The Linux and FreeBSD implementations of Euphoria let you access C routines and variables in shared libraries, for tasks ranging from graphics, to X windows GUI programming, to Internet CGI programming. The good news is, youll be programming in Euphoria, not C.
- A complete open source (Public Domain) Euphoria interpreter, written in Euphoria, is included in the download package. It can execute any Euphoria program on any platform. An optional high-performance C-coded back-end for this interpreter is available for just $79. See the Source License.
