  • Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features:

    Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features: * Creates a virtual encrypted disk within a file and mounts it as a real disk. * Encrypts an entire partition or storage device such as USB flash drive or hard drive. * Encrypts a partition or drive where Windows is installed (pre-boot authentication). * Encryption is automatic, real-time (on-the-fly) and transparent. * Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data). * Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS. Further information regarding features of the software may be found in the:http://www.truecrypt.org/

    This article describes how to consume Web services in Java 1.5.0 using the new JAX-WS 2.0 API (JSR 228). Developers around the world, including me, have always complained about the hard ways to work in Java to consume even a Web service as simple as adding two numbers. However, with JAX-WS 2.0 API now available in core Java in JDK 1.5.0, life is simple like never before.

  • We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder f

    We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fields, so that the anisotropy ratio tends to infinity, the D and B fields blow up near the cloaking surface. Since the metamaterials used to implement cloaking are based on effective medium theory, the resulting large variation in D and B will pose a challenge to the suitability of the field averaged characterization of " and 碌. We also consider cloaking with and without the SHS (softand- hard surface) lining, shown in [6] to be theoretically necessary for cloaking in the cylindrical geometry. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of D and B prevented.

  • Although some FX1-based devices may use the FX1鈥檚 CPU to process USB data directly (Port I/O Mode),

    Although some FX1-based devices may use the FX1鈥檚 CPU to process USB data directly (Port I/O Mode), most applica- tions use the FX1 simply as a conduit between the USB and external data-processing logic (e.g., an ASIC or DSP, or the IDE controller on a hard disk drive).

  • This book is for someone who wants to quickly master the basics of how to install, run, and maintai

    This book is for someone who wants to quickly master the basics of how to install, run, and maintain Linux on an Intel-based personal computer. All of the tools you need are included. Your computer should have a monitor, or display, keyboard, mouse, hard drive, floppy drive, and CD-ROM drive. Although you can jump right in and install Linux onto your hard drive, you should have some technical information about your computer and its hardware on hand before you start.
