  1. Constraint validation

    When the user agent is required to statically validate the constraints of form element form, it must run the following steps, which return either a positive result (all the controls in the form are valid) or a negative result (there are invalid controls) along with a (possibly empty) list of elements that are invalid and for which no script has claimed responsibility.

Transparency is also supported with lossy compression and typically provides 3x smaller file sizes compared to PNG when lossy compression is acceptable for the red/green/blue color channels.

    The page provides a downloadable converter.

  140. Write Code Every Day

    I decided to set a couple rules for myself:
    1. I must write code every day. I can write docs, or blog posts, or other things but it must be in addition to the code that I write.
    2. It must be useful code. No tweaking indentation, no code re-formatting, and if at all possible no refactoring. (All these things are permitted, but not as the exclusive work of the day.)
    3. All code must be written before midnight.
    4. he code must be Open Source and up on Github.

    Some useful guidance.

  141. Hacker News

    Probably the best overall one-stop source. The comments are often especially valuable. Requires commitment.

  142. The Changelog

    The Changelog is a member supported blog, weekly newsletter and podcast that covers the intersection of software development and open source.

    They pay attention to Hacker News and have good podcasts. Lots of node.js stuff.

  143. MDN HTML5 Guide

    Designed to be usable by all Open Web developers, this reference page links to numerous resources about HTML5 technologies, classified into several groups based on their function.

    a mathematician / economist / statistician by schooling, a data scientist by trade, and a python hacker by night, (pronounced skīəns) is my blog aimed to track explorations in all of the above.

    Useful blog on python and general programming.

  145. Bower

    Bower is a package manager for the web. It offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat.
  146. Flat UI Colors

    This small web app helps you to copy the colors from Flat UI. It's kind of responsive, so you can use it with a tiny browser like a widget. I'll be providing more small apps like this, so if you are interested follow me @ahmetsulek.
  147. iHover

    CSS3 hover effects pack. iHover is an impressive hover effects collection, powered by pure CSS3, no dependency, work well with Bootstrap 3!

    See especially hover effect 13.

  148. Magic Animation CSS3

    Come sapete, amo molto il linguaggio CSS ed in particolare mi piace sempre andare oltre, in questo caso ho voluto creare un pacchetto di animazioni in CSS3 che potrete usare liberamente per i vostri scopi e quindi nei vostri progetti web, si chiama Magic!

    Slightly over the top, and not exactly an original resource, but a good spin on it. Great background!
