Big-O Algorithm Complexity Cheat Sheet 40 Cool jQuery Animation Tutorials Since its arrival, jQuery has caught the web by storm and now it is one of the preferred solutions in creating fancy animations on web pages. jQuery provides great cross browser support, it is lightweight and easy to use. Right now, you can see jQuery effects applied in a number of ways that effectively demonstrate its power to define and control small-scale web animations. Until newer technologies like CSS3 fully mature with adequate support from major browsers and all, jQuery will continue the lead. We will still be seeing a lot of its application in navigation interfaces, sliders and other image display mechanisms, in enhancing web typography and more going forward. Therefore, to help you work your way around jQuery, I am sharing with you some of the best jQuery animation tutorials and plugins I have been able to find. Keep in mind though, that all major web standards and frameworks develop at light speed. Advertisement jQuery Animation Tutorials jQuery.Parallax – MORE INFO / DEMO
Essential Math for Games Programmers As the quality of games has improved, more attention has been given to all aspects of a game to increase the feeling of reality during gameplay and distinguish it from its competitors. Mathematics provides much of the groundwork for this improvement in realism. And a large part of this improvement is due to the addition of physical simulation. Creating such a simulation may appear to be a daunting task, but given the right background it is not too difficult, and can add a great deal of realism to animation systems, and interactions between avatars and the world. This tutorial deepens the approach of the previous years' Essential Math for Games Programmers, by spending one day on general math topics, and one day focusing in on the topic of physical simulation. It, like the previous tutorials, provides a toolbox of techniques for programmers, with references and links for those looking for more information. Topics for the various incarnations of this tutorial can be found below. Slides

Eulerian Video Magnification banner slider Many seemingly static scenes contain subtle changes that are invisible to the naked human eye. However, it is possible to pull out these small changes from videos through the use of algorithms we have developed. We give a way to visualize these small changes by amplifying them and we present algorithms to pull out interesting signals from these videos, such as the human pulse, sound from vibrating objects and the motion of hot air. Videos Software and Code Eulerian Video Magnification code Matlab code and executables implementing Eulerian video processing for amplifying color and motion changes. Phase Based Video Motion Processing code Matlab code for implementing the new and improved phase-based motion magnification pipeline. Videoscope Web interface for motion and color magnification.

Best Practices for Designing a Pragmatic RESTful API | Vinay Sahni Your data model has started to stabilize and you're in a position to create a public API for your web app. You realize it's hard to make significant changes to your API once it's released and want to get as much right as possible up front. Now, the internet has no shortage on opinions on API design. But, since there's no one widely adopted standard that works in all cases, you're left with a bunch of choices: What formats should you accept? In designing an API for SupportFu (a lightweight Zendesk alternative ), I've tried to come up with pragmatic answers to these questions. ... or just skip to the bottom and signup for updates Key requirements for the API Many of the API design opinions found on the web are academic discussions revolving around subjective interpretations of fuzzy standards as opposed to what makes sense in the real world. An API is a developer's UI - just like any UI, it's important to ensure the user's experience is thought out carefully! Use RESTful URLs and actions

Contents About the operation counting methodology When totaling the number of operations for algorithms here, any C operator is counted as one operation. Compute the sign of an integer The last expression above evaluates to sign = v >> 31 for 32-bit integers. Alternatively, if you prefer the result be either -1 or +1, then use: sign = +1 | (v >> (sizeof(int) * CHAR_BIT - 1)); // if v < 0 then -1, else +1 sign = (v ! Patented variation: f = v && ! Sean A.

Public Domain Aeronautical Software (PDAS) Great Reads from Kira Talent | Recruitment Best Practices Blog One thing that’s not taught in school is technical recruiting. You develop skills to become a better programmer, get trained on how to perform well in interviews, but it’s always assumed that it will either take years before you’re in a position to interview a potential hire, or that the company you’re currently working for will teach you their secrets. As a result, I’ve put together a list of my recommend “must-reads” below that covers topics of recruiting, hiring and interviewing from various thought leaders in the industry. Reading all of these won’t turn you into an all-star technical recruiter overnight, but they will help you understand the fundamentals, key things to stay away from and best practices from people who have been doing it (and doing it well) for years. If you’re a technical recruiter, Joel Spolsky is a must-known name. He often writes on everything in recruiting/interviewing technical talent, and here are the top 5 posts by him: Good luck!
Octave GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Octave is distributed under the terms of the GNU General Public License. Version 4.0.0 has been released and is now available for download. An official Windows binary installer is also available from Thanks to the many people who contributed to this release!
