Easy-to-Use, Ultra-Tiny, Differential, 16-Bit Delta Sigma ADC With I2C Interface
The LTC2453 is an ultra-tiny, fully differential, 16-bit, analog-to-digital converter. The LTC2453 uses a single 2.7V to 5.5V supply and communicates through an I2C interface. The ADC is available in an 8-pin, 3mm x 2mm DFN package. It includes an integrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and has no latency for multiplexed applications. The LTC2453 includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude lower than conventional delta-sigma converters. Additionally, due to its architecture, there is negligible current leakage between the input pins.
MIDlet通過藍(lán)牙與電腦通信的案例,This resource demonstrates how to create Java™ applications that use Bluetooth communication between a PC and a mobile device. The document focuses, from Java programming point of view, on how to configure and use two alternative PC-side solutions: COM-based and JSR-82-based solutions. The package includes several code examples both for PC and mobile devices.
The tool presented below tries to detect from remote if the target machine was compromised with the HACKER Defender rootkit. The tool connect to the remote host, and compares the reply to several known replies. The rootkits that can be detected by the tool are: HACKER Defender v1.0.0 and below.
A Case Study: Replacing the persistence layer of a
Business Process Engine with JDO
The JDO specification (JSR-12) was released from the Java Community Process in April
2002. Its goal is to provide transparent persistence to Java classes. David Jordan provides
a concise introduction. several books are becoming available that provide a more complete description of JDO3.
This sample demonstrates compression capabilities available in the .NET Framework. It builds a Windows Forms application that employs the GZipStream and DeflateStream types to compress and decompress files. The sample also introduces several types that are new in the .NET Framework version 2.0.
When working with mathematical simulations or engineering problems, it is not unusual to handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot of resource for nothing!
This article presents a fast 2D-line approximation algorithm based on the Douglas-Peucker algorithm (see [1]), well-known in the cartography community. It computes a hull, scaled by a tolerance factor, around the curve by choosing a minimum of key points. This algorithm has several advantages:

As science advances, novel experiments are becoming more and more complex, requiring a zoo of control devices and electronics executing complicated sequences of steps. Device availability and monetary constrains usually lead to a highly heterogeneous setup with components from several different manufacturers using many different protocols and interfacing mechanisms. This often results in control software being puzzled together to use and provide a multitude of interfacing and control functionality, each using their own calling conventions, data structures, etc. To make matters worse, usually a group of relatively independent programmers is trying to write and maintain the code base. Often this causes extensive duplication of effort as program segments are hard to reuse, since unpredictable changes to the segments by the original authors might compromise other code using these segments.
ET++ is a portable and homogenous object-oriented class library integrating user
interface building blocks, basic data structures, and high level application framework
components. ET++ eases the building of highly interactive applications with consistent
user interfaces following the direct manipulation principle. The ET++ class library is
implemented in C++ and can be used on several operating systems and window system
platforms. Since its initial conception the class library has been continuously
redesigned and improved. It started with an architecture which was close to MacApp.
During several iterations a new and unique architecture evolved. A byproduct of the
ET++ project is a set of tools, which were designed to support the exploration of ET++
applications at run-time.

北京大學(xué)ACM比賽題
The game of Scrabble is played with tiles. A tile either has a single letter written on it, or it is blank. In the latter case, the tile may be used to represent a letter of your choice. On your turn, you arrange the tiles to form a word. Each tile may be used at most once, but not all tiles need to be used. Given several Scrabble tiles and a dictionary, determine how many words in the dictionary can be formed using the given Scrabble tiles.
Tasks
Read the textbook about the details of Vigenére Cipher.
Implement the algorithm by C or C++.
