PredictionIO is an open source prediction engine that allows developers to implement predictive features to their sites/apps.

Such predictive features can be the recommendations of videos, articles, deals, photos or documents, restaurants, etc. that are specific to a given user (which we see in many sites).

The application is designed to work with big data (supports Hadoop, Mahout, Cascading and Scalding) and has SDKs for major programming/scripting languages (Ruby, Python, Java and -soon- PHP).

It has a REST API for integrating the prediction features into apps and an admin interface helps setting up everything.

PredictionIO can be installed on any platform (runs on JVM), it is in the beta phase but still very valuable considering it is hard to find an alternative in that field.

If you prefer creating websites using WordPress and make use of ready-to-use themes, MightyDeals has an offer that you may like.

MightyDeals, the creative deals website, is offering a pack of 17 high-quality WordPress themes by DX Themes for a very good price ($17 rather than $289).

The themes in the bundle include ones for creatives, businesses, parents/kids, hotels and much more.

All of them work cross-browser and most are responsive down-to-mobile.

It is possible to find features like portfolio management, responsive image sliders, AJAX contact forms, custom sidebars, testimonial widgets, price tables, SEO control, etc.

To sum up, even if only a single item in the bundle, will be a fit for a project of yours, it is still a good deal.

When working on a project, after each CSS or JavaScript update, the need to refresh the browser is a time-loss (and it is usually done 10s of times).

Tincr, a Chrome extension, solves this by integrating itself into Chrome’s Developer Tools and auto-refreshing the browser once these files are changed.

It is not bound to any IDE and works with all of them. There are several built-in project types (Ruby on Rails, Chrome extensions, Atlasian projects..) and custom ones can be created for any custom CSS/JS structure.

Also, it -kinda- converts the Developer Tools into an IDE by adding an auto-save feature to changes made to the code from Developer Tools

The dynamic column grid layouts are so popular not only because it is used by Pinterest but also because it is a great way of displaying content with different sizes.

Wookmark, a Pinterest alternative, has released a jQuery plugin for creating such layouts, that work well on each browser, instantly.

The plugin has very few options to set: the container element, offset (vertical/horizontal distance) and width of the items, that’s all.

Once initialized, it gets the size of the window and auto-arranges the grid (yes, it is responsive).

For NoSQL fans, MongoDB is definitely the most popular solution with the simplicity and cross-platform support offered.

In order to manage MongoDB databases easily, Genghis, a single-file, self-hosted and web-based solution is pretty handy.

It can be installed either as a Ruby gem or as a standalone PHP script.

Genghis is capable of managing any number of databases on any number of servers with support for managing databases, collections and documents.

The interface of the application is responsive and works well down to mobile.

There are many creative uses of symbol fonts and Stately is definitely one of them.

The font is for creating US maps where states are glyphs within the font. Each state is positioned and sized relative to the the rest of the states so that they play well with each other.

It is possible to style each state with only CSS, scale them to any size or manipulate with JavaScript.

As a wish, how great would it be if there was a world map version : ).

Maplace.js is a jQuery plugin that simplifies integrating Google Maps into websites.

It works with the latest Google Maps API (v3) and has methods for adding markers + custom content and drawing paths, polygons or routes.

There are options for defining the zoom level or controls to be displayed (zoom, map/satellite..).

The plugin allows customizing almost everything from the icons used to texts and colors.

It has callbacks on each action and comes with a very well documentation.

All browsers have different behaviors while rendering web pages. Even their versions have inconsistencies.

Although this is a bad thing, it is possible to make use of these inconsistencies for targeting the right browser and the right version (which is sometimes handy for debugging or applying code that will only be applied by the browser wanted).

Browserhacks is a website which presents a list of browser-specific CSS and JavaScript hacks.

It is a single-page resource, includes hacks for Chrome, Safari, Firefox, IE + Opera and has a cool search box that eases finding the right hack instantly.

P.S. The project is open source and it is possible to contribute it with any new hacks.

CanvasQuery is a JavaScript library that eases working with HTML5 canvas and adds lots of new methods to it.

The library provides a jQuery-like syntax and methods added are mostly for image manipulation (like masks, blur, crop or fill mask).

It also brings blend modes, new shapes, text wrapping and much more.

CanvasQuery can be used with or without jQuery, has methods for color conversion and can be extended with plugins.

Spectrum is a jQuery colorpicker plugin that probably comes with all the features you are looking for.

It is image-free (only CSS and JS) and can be used for all browsers or only as a polyfill for the input[type=color] of HTML5 .

The picker is actually familiar to designers/developers as it is the same one that comes with WebKit DevTools (created by the same developer) but now available as a jQuery plugin.

It has support for color palettes by storing/displaying the colors you chose, the default selected color can be set or it can be configured to only display the palette with pre-defined colors.

Alpha transparency selection is available, can be always visible (without clicking to a picker icon) and supports multiple color formats.

Spectrum can be customized with CSS and it works on mobile as well.
