HBase - Installing Apache HBase (TM) on Windows using Cygwin Introduction Apache HBase (TM) is a distributed, column-oriented store, modeled after Google's BigTable. Apache HBase is built on top of Hadoop for its MapReduce and distributed file system implementation. All these projects are open-source and part of the Apache Software Foundation. As being distributed, large scale platforms, the Hadoop and HBase projects mainly focus on *nix environments for production installations. Purpose This document explains the intricacies of running Apache HBase on Windows using Cygwin as an all-in-one single-node installation for testing and development. Installation For running Apache HBase on Windows, 3 technologies are required: Java, Cygwin and SSH. Java HBase depends on the Java Platform, Standard Edition, 6 Release. Cygwin Cygwin is probably the oddest technology in this solution stack. To support installation, the setup.exe utility uses 2 directories on the target system. Make sure you have Administrator privileges on the target system. HBase Configuration

HTML5 Reset :: A simple set of templates for any project scrollorama Disclaimer: This is an experimental, just-for-fun sort of project and hasn’t been thoroughly tested. Design and build your site, dividing your content into blocks. Embed scrollorama.js after jQuery and initialize the plugin, passing the blocks class selector as a parameter. Target an element and animate its properties. The animation parameters you can use are: Hook into the onBlockChange event. scrollorama.onBlockChange(function() { alert('You just scrolled to block#'+scrollorama.blockIndex); }); Note: If you are not using the pinning feature, it is recommended you disable it.

Apache HttpComponents - Apache HttpComponents Sliding content | CSS3 transitions, transforms and animations Often used as part of an image gallery or to show additional information, again this can be done in javascript by gradually changing the padding of elements. This often looks choppy on mobile devices, and frames can be missed if the animation is quick. CSS transitions plus transforms help out to make this a simple effect to create. Have a look at a more complete example on the demos page. Note: Animating by transitioning transforms is hardware accelerated on iOS, making this a good option there. Plan Create a container with overflow set to hidden. Demo Image 1Image 2Image 3Image 4 Code The CSS looks like this: The rather simple JS looks like this. $(document).ready(function() { $('#slide1_controls').on('click', 'span', function(){ $("#slide1_images").css("transform","translateX("+$(this).index() * -450+"px)"); $("#slide1_controls span").removeClass("selected"); $(this).addClass("selected"); });});
