Many applications use connection/object pool. A program may require a IMAP connection pool and LDAP connection pool. One could easily implement a IMAP connection pool, then take the existing code and implement a LDAP connection pool. The program grows, and now there is a need for a pool of threads. So just take the IMAP connection pool and convert that to a pool of threads (Copy, paste, find, replace????). Need to make some changes to the pool implementation? Not a very easy task, since the code has been duplicated in many places. Re-inventing source code is not an intelligent approach in an object oriented environment which encourages re-usability. It seems to make more sense to implement a pool that can contain any arbitrary type rather than duplicating code. How does one do that? The answer is to use type parameterization, more commonly referred to as templates.
MIB Browser allows you to view the hierarchy of SNMP MIB variables in the form of a tree and provides you with additional information about each node.
With MIB Browser you can easily load (compile) standard and proprietary MIB files, view and manipulate data that is available in an SNMP agent.
A dynamic-link library (DLL) contains one or more subprogram procedures
(functions or subroutines) that are compiled, linked, and stored separately from
the applications using them. Because the functions or subroutines are separate
from the applications using them, they can be shared or replaced easily.
可在系統引導時工作的RootKit,較簡單
1) It s very small.The basic framework is just about 100 lines of assembly code.It supports 2000,XP,2003
2) It patches the kernel at runtime(no files are patched on disk).(basic version has this code removed , so as others could understand it easily).
3) BOOT KIT is PXE-compatible.
4) It can even lead to first ever PXE virus
5)It also enables you to load other root kits if you have physical access(Normally root kits can only be loaded by the administrator)
This book is intended for "hands-on" developers or advanced students interested in understanding the strategies and tactics of concurrent network programming using C++ and object-oriented design. We describe the key design dimensions, patterns, and principles needed to develop flexible and efficient concurrent networked applications quickly and easily. Our numerous C++ code examples reinforce the design concepts and illustrate concretely how to use the core classes in ACE right away. We also take you "behind the scenes" to understand how and why the IPC and concurrency mechanisms in the ACE toolkit are designed the way they are. This material will help to enhance your design skills and to apply C++ and patterns more effectively in your own object-oriented networked applications.
The extraordinary growth of the World Wide Web has been fueled by the ability it gives authors to easily and cheaply distribute electronic documents to an international audience. As Web documents have become larger and more complex, however, Web content providers have begun to experience the limitations of a medium that does not provide the extensibility, structure, and data checking needed for large-scale commercial publishing. The ability of Java applets to embed powerful data manipulation capabilities in Web clients makes even clearer the limitations of current methods for the transmittal of document data.
This is a little console mode utility program which is able to
(de-)compress single files with a static Arithmetic compression
algorithm. You could easily add the RLE/BWT/MFT data
transformation algorithms. Just rip the corresponding classes
out of my HuffComp source code. I won t add these ones in the
next time.
Address book helps you look up your addresses from the system tray.
It is quite useful in that way 慶ause it stays out of the way and is
easily accessible when needed. Double clicking on any URL will start
the default web browser and take you to that URL. Double clicking on
the phone number will dial that number. Every column supports
sorting and can be customized to your needs. Preview will display
the notes associated with each record.
This program can also import Comma Separated Values (*csv) text files
of Outlook Express.
LemonSMS is a component developed in Java that provides a turnkey solution for application developers to incorporate into their Java applications the functionality of sending and processing of incoming SMS messages.
LemonSMS acts as a middleware between a Java application and a GSM Modem or Data enabled phone. Because LemonSMS only provides an interface to the added SMS functionality, your application still handles access to data and business logic tier. With the easy-to-use LemonSMS API, developers can easily utilize SMS functionalities provided by LemonSMS.
it contains many classic Test Problems for Unconstrained Optimization such as camel6,treccani,goldstein,branin,
shubert1,Ackley,dejong,dejong1,dejong2,
dpower,rastrigin,Griewangk,Schwefel,
rosenbrock2 and step.
the package have the contour and mesh figures of these problem.
it also give m files of these problems,and
you can easily get your view of figures.
