The following libraries seem to have interesting functionality, high development activity and good user feedback (+1). The Floating-Point Guide - What Every Programmer Should Know About Floating-Point Arithmetic. Elegant Coding: Eleven Equations True Computer Science Geeks Should (at Least Pretend to) Know. This idea is a complete rip off an article that appeared in Wired a little while ago and it got me thinking what would my list for Computer Science look like?
Plus I thought it might be a fun post and unlike the Wired list this one goes to eleven. Logique et calcul : Les chiffres de la complexité informatique. Why Do Computers Suck at Math? You've probably seen this old chestnut by now.
Insert your own joke here. Google can't be wrong -- math is! But Google is hardly alone; this is just another example in a long and storied history of obscure little computer math errors that go way back, such as this bug report from Windows 3.0. Start Calculator. Input the largest number to subtract first (for example, 12.52). On my virtual machine, 12.52 - 12.51 on Ye Olde Windows Calculator indeed results in 0.00. Client-side JavaScript Vulnerabilities.
Creating a Facebook app with Google App Engine and Google Web Toolkit (GWT) One of the challenges with writing a presumably successful Facebook application is taking care of scale. with an ever growing user base and the high viral growth potential brought by this social platform you could be looking at a very high traffic if your application is successful.

Especially for small and medium enterprises which can find the cost model beneficial for their first baby steps. This post is not going to dwell on the details of creating an App Engine account or a Facebook application. RestFB - A Lightweight Java Facebook Graph API and Old REST API Client. HTML5 Canvas Image Effects: Black & White. The new canvas tag in HTML5 is known for its illustration power.
It’s basically an empty element on which you can write and sketch using Javascript. But there’s a hidden power: image manipulation. In our opinion, this is the most important element that differs from SVG. With canvas you can perform operations on pixel based artworks. You can write a new image pixel by pixel or import an image in the canvas and modify it as you need. In this article we’ll show you some fundamentals of pixel manipulation in the canvas, and how to use this knowledge to obtain interesting effects. Importing Bitmap Image On Canvas. Using HTML5 Canvas To Turn Image Into Grayscale. HTML 5 introduces Canvas object which can be used to draw and manipulate images. In this example, I used a Canvas to turn an image into grayscale. If your browser supports Canvas , you should see two images above: the normal image and the grayscale one. PDF.
Dictionary of Algorithms and Data Structures. This web site is hosted by the Software and Systems Division, Information Technology Laboratory, NIST. Development of this dictionary started in 1998 under the editorship of Paul E. Black. After 20 years, DADS needs to move. If you are interested in taking over DADS, please contact Paul Black. This is a dictionary of algorithms, algorithmic techniques, data structures, archetypal problems, and related definitions. Don't use this site to cheat. Currently we do not include algorithms particular to business data processing, communications, operating systems or distributed algorithms, programming languages, AI, graphics, or numerical analysis: it is tough enough covering "general" algorithms and data structures.
Hasan's Weblog ~ Experiences @ workspace. FileUpload with GWT I need a file upload solution in my Google Web Toolkit (GWT) project. While googling, I have found many related posts asking about the subject. Also, there are some projects arround providing this functionality. But, I couldn't find any tutorial explaining the file upload solution from start to end or building a sample application to demonstrate the ability on GWT. So that, I have decided to write my experiences here to help to the developers in need. If you don't want to use/depend any other (may be not mature and extendible enough) third party library just to make a simple file upload operation, and want to develope your clean and extendible solution, then, go on and follow the steps below :)
