Blast.js separates text in order to facilitate typographic manipulation. It has four delimiters built in: character, word, sentence, and element. Alternatively, Blast can match custom regular expressions and phrases.
Blast is highly accurate; it neither dumbly splits words at spaces nor dumbly splits sentences at periods. Features include: 1) By traversing text nodes, all HTML, event handlers, and spacing are preserved. Thus, you can safely apply Blast to any part of your page. 2) Automatic class and ID generation make text manipulation simple. 4) Blast can be fully undone with a single call. 5) All Latin alphabet languages and UTF-8 characters are supported.

Pakyow is an open-source framework for the modern web. Build working software faster with a development process that remains friendly to both designers and developers. It’s built for getting along. Pakyow empowers the designer with a view-first development process.
The views are created in isolation from the back-end app, giving the designer complete control over the front-end through the entire development process. You can create a working, navigable prototype of your app without writing a line of back-end code. Later, add the back-end as a layer on top of the view, leaving the prototype intact.

Requirements: Ruby

If you’re reading this blog post probably you’re the last person in the world who decided to learn responsive web design. Well it’s never too late to learn. Here you will learn the bare essentials of RWD, and after reaching the end you will know where to start and what you need to do. So let’s scroll.

To understand the principles of responsive design you need to know three things that make the basis of this design principle. The first thing is the “viewport” tag.
Meta Tag Viewport
Most mobile browsers scale the HTML page so that it will fit on the width of the full-screen devices. Using the tag “viewport” you can eliminate such behavior of browsers. Meta tag “viewport” with values listed below tells the browser to use the width of the window unit and disable the initial scaling. Include this meta tag into the <head>.
There have always been certain troubles with Internet Explorer browsers. So when it comes to RWS once again you will understand why everyone hates so much IE. IE8 and older versions do not support media queries. You can use a specially designed java-script or media-queries.js respond.js to add media query support in IE. To make this work you need to use conditional comments, as shown below: Read the rest of this entry »
Crate Data is a shared-nothing, fully searchable, document-oriented cluster data store. It is also 100 % open source. They built it so developers with a data intensive back-end won’t need to “glue” several technologies together to store documents, blobs and support real-time search.
They also wanted to help developers avoid the manual work associated with tuning, sharding, replication and other operations required to keep a large de-normalized data store in good shape. They wanted a simple, failure-tolerant and massively scalable data store anyone can use, on a single machine, many machines or on the cloud.

HTML Minifier is a highly configurable, well-tested, Javascript-based HTML minifier, with lint-like capabilities. At its core, minifier relies on HTML parser by John Resig. John’s parser was capable of handling quite complex documents, but would sometimes trip on some of the more obscure structures. For example, doctype declarations were not understood at all.
HTML minifier is fully unit tested with ~100 tests at the moment. This has few benefits: anyone can change, tweak or add things without worrying to break existing functionality. It takes literally seconds to tell if script is functional in certain browser simply by running a test suite. Finally, tests can serve as documentation for how minifier handles some of the edge cases.
