KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware. It consists of a loadable kernel module (kvm.ko) and a userspace component.
Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
The kernel component of KVM is included in mainline Linux, and will appear in Linux 2.6.20.
KVM is open source software.

Description
Given any integer 0 <= n <= 10000 not divisible by 2 or 5, some multiple of n is a number which in decimal notation is a sequence of 1 s. How many digits are in the smallest such a multiple of n?
initial working phase of the design of said editor,
featuring multicasting, advanced linux keyboard handling,
sub-hierarchical expansion, and multiple cursors (similar
to the concept found in moonedit). The author respectfully requests your compliance with the GPL
Securing Apache 2: Step-by-Step
When choosing a web server, Apache very often wins against its competitors because of stability, performance, that fact that it s open source, and many other advantages. But when deciding on which version of Apache to use, the choice is not always so simple. On the one hand there is a very popular, stable version used by millions of users, version 1.3, and on the other hand, there is an enhanced and re-designed version 2.0.
This a collection of sample processes that provide examples ranging from
how to use a particular BPEL activity such as pick or scope, to more complex
examples of processes that invoke external Web services or show techniques
such as handling multiple start messages.
KphoneSI (kpsi) is a SIP (Session Initiation Protocol) user agent

over the Internet, send Instant Messages, subscribe your friends
presence information and start other applications of your choice
Mobile phones are constantly decreasing in size, thereby complicating the acoustical
functionality. Signal processing methods can be used to partially mitigate
this problem. In this paper we suggest a method which uses multiple spectral
subtraction functions and two microphones, introducing only a short signal delay.
These two classes show an extremely simple example of java.net socket programming. They implement the Unix daytime protocol, an extremely simple protocol that consists entirely of the server sending its current local time and date to the client as an ASCII string. The server, to keep it very simple, does not use multiple threads. This code requires JDK 1.1 or later, but can easily be adapted to JDK 1.0.
About:
hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases.
Release focus: Major feature enhancements
Changes:
This release comes with many changes and new features. It can manage multiple databases in one file. A new flag (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download.
