Wiimote Wireless Modification for Persons with Disabilities The materials for this step are as requires: • 2 Arduino Duemilanove USB Boards (Sparkfun, SKU: DEV-00666) • 2 Arduino Xbee Empty Shields (Sparkfun, SKU: DEV-09063) • 2 Xbee 1 mW Chip Antenna (Sparkfun, SKU: WRL-08664) • 1 Standard USB Cable A-B (Adafruit Industries) • X-CTU Software ( • Arduino Software (• 1 9V Regulated DC Wall Power Adapter (Adafruit Industries) • 1 9V Battery Holder with Switch and 2.1 mm Plug (Adafruit Industries) • 1 9V Battery The first step is to configure the Xbee chips so that they are able to communicate effectively with each other. Xbee chip configuration requires the X-CTU Software. 1. Download and install the X-CTU Software from the Digi website 2. CAREFULLY remove the microprocessor from the Arduino board.

Getting Started Getting Started will guide you through the process of adding Metrics to an existing application. We’ll go through the various measuring instruments that Metrics provides, how to use them, and when they’ll come in handy. Setting Up Maven Just add the metrics-core library as a dependency: <dependencies><dependency><groupId>com.codahale.metrics</groupId><artifactId>metrics-core</artifactId><version>${metrics.version}</version></dependency></dependencies> Import and Export Bulk Data by Using the bcp Utility (SQL Server) This topic provides an overview for using the bcp utility to export data from anywhere in a SQL Server database where a SELECT statement works, including partitioned views. The bcp utility (Bcp.exe) is a command-line tool that uses the Bulk Copy Program (BCP) API. The bcp utility performs the following tasks:

Les Misérables Co-occurrence Source: The Stanford GraphBase. A network can be represented by an adjacency matrix, where each cell ij represents an edge from vertex i to vertex j. Here, vertices represent characters in a book, while edges represent co-occurrence in a chapter. Given this two-dimensional representation of a graph, a natural visualization is to show the matrix!

The first lighted mousepad; GlowPad in the world by MetkuMods First time in English. Please, be easy on me :) So, this is the project that I started to do something about these old and outdated mouse pads, maybe to add some more "glow" to them. So there you have it. Monitoring Made Easy Hello and welcome to Java-monitor, Java-monitor is the free, on-line monitoring service for Tomcat, Glassfish, JBoss, Jetty and Openfire. We send you an e-mail when you server goes off-line. You can see trends in your JVM memory use, its garbage collectors, your UNIX file descriptors, JVM threads, database connections, Hibernate statistics and much more. From here you can do two things: if you are not sure what Java-monitor is, you can read the information below and look at the live demo to see Java-monitor in action.

Lazy evaluation The benefits of lazy evaluation include: Performance increases by avoiding needless calculations, and error conditions in evaluating compound expressionsThe ability to construct potentially infinite data structuresThe ability to define control flow (structures) as abstractions instead of primitives Lazy evaluation is often combined with memoization, as described in Jon Bentley's Writing Efficient Programs.[4] After a function's value is computed for that parameter or set of parameters, the result is stored in a lookup table that is indexed by the values of those parameters; the next time the function is called, the table is consulted to determine whether the result for that combination of parameter values is already available. If so, the stored result is simply returned. If not, the function is evaluated and another entry is added to the lookup table for reuse. The opposite of lazy evaluation is eager evaluation, sometimes known as strict evaluation.

Graphing Every* Idea In History « Griff's Graphs Update: Graph has now been made interactive. I was originally put onto network visualisation by Simon Raper by his fantastic post graphing the history of philosophy. I’ve learned a lot in the last week and decided to be ambitious. I wanted to see what the entire network would look like – with everyone on Wikipedia. Well, everyone with an infobox containing ‘influences’ and/or ‘influenced by’. For those unfamiliar to this work please see his post first – even if it is just for the pictures!

Homemade arduino printer If you want to make your own high resolution printer (maybe not so high res), you are at the right place. This Instructable will show you how to do with two dead cd/dvd drive and a pen (pilot, whiteboard marker, whatever you have) at the best lego-printer style. Here is how our printer will work: we type any message in terminal then the message will be printed (as dot matrix) and after the message is printed the program will wait for another message. For this magnificent printer you will need: 1) 1 x Arduino (I've used the Duemilanove) 2) 2 x H-Bridge (SN754410) 3) 3 x small dc motors from any cd/dvd drive 4) 3 x switches from the same cd/dvd drive 5) A pen or marker 6) Wire 7) Rubber string 8) Sheave 9) Stick with round rubber like the rollers in a real printer, the wheels from a toy car should work. 10) Acrylic, wood or whatever you have to build the structure. 11) 5v and 9v power supply

javamelody - monitoring of JavaEE applications The goal of JavaMelody is to monitor Java or Java EE application servers in QA and production environments. It is not a tool to simulate requests from users, it is a tool to measure and calculate statistics on real operation of an application depending on the usage of the application by users. JavaMelody is opensource (ASL) and production ready: in production in an application of 25 person years. JavaMelody is easy to integrate in most applications and is lightweight (no profiling and no database). JavaMelody is mainly based on statistics of requests and on evolution charts.

clumsy, an utility for simulating broken network for Windows Vista / Windows 7 and above Releases Notice: clumsy only support Windows Vista, Windows 7 and above. 64bit Windows users are strongly recommanded to download the 64bit build. 32bit: (MD5:b8eb28c399f15f02112f5461f6465153) 64bit: (MD5:e75419e28321cdc2cb4ca6f9e4044fd0) Install Extract downloaded zip file to arbitrary directory and execute clumsy.exe. clumsy is alpha quality software and does have some gotchas. Be sure to read the manual page before using it. Citeology - Projects Update: We have submitted a Citeology paper to alt.CHI which you can download here. Citeology looks at the relationship between research publications through their use of citations. The names of each of the 3,502 papers published at the CHI and UIST Human Computer Interaction (HCI) conferences between 1982 and 2010 are listed by year and sorted with the most cited papers in the middle. In total, 11,699 citations were made from one article to another within this collection. These citations are represented by the curved lines in the graphic, linking each paper to those that it referenced. While you are waiting for the applet to load, here are some sample Citeologies:
