TinyPNG uses smart lossy compression techniques to reduce the file size of your PNG files. By selectively decreasing the number of colours in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large difference in file size!
Clears the junk out of your CSS by finding out which selectors are actually not used in your HTML.
Why?
With the onslaught of Twitter Bootstrap upon the world it's very tempting to just download their whole fat 80+Kb CSS and serve it up even though you're not using half of the HTML that it styles.
There's also the case of websites that have changed over time but without the CSS getting the same amount of love refactoring. Then it's very likely that you get CSS selectors that you're no longer or never using.
This tool can help you get started reducing all those selectors that you're not using.
Whitespace compression?
No, that's a separate concern. This tool works independent of whitespace compression/optimization.
For example, if you have a build step or a runtime step that converts all your CSS files into one (concatenation) and trims away all the excess whitespace (compression) then the output CSS can still contain selectors that are never actually used.

Modular programming is used to break large applications into smaller blocks of manageable code. Module based coding eases the effort for maintenance and increases reusability. However, managing dependencies between modules is a major concern developers face throughout the application development process. RequireJS is one of the most popular frameworks around for managing dependencies between modules. This tutorial examines the need for modularized code, and shows how RequireJS can help.

Leak finder for JavaScript helps web application developers find memory leaks in their JavaScript programs.
In garbage-collected languages, such as JavaScript, you cannot have traditional memory leaks by forgetting to free memory: when all references to an object are dropped, the object is garbage-collected and the memory is freed.
However, JavaScript programs can leak memory by unintentionally retaining references to objects. For example the references can be pointers to objects stored in a data structure in a JavaScript library (e.g., Closure) instead of the application code. If an object is unintentionally retained, all objects it points to are kept alive as well. This will lead to superfluous memory consumption.

One of the easiest ways to improve your application’s performance is by putting a caching solution in front of your database. In this tutorial, I’ll show you how to use Memcached with Rails, Django, or Drupal.
Memcached is an excellent choice for this problem, given its solid history, simple installation, and active community. It is used by companies big and small, and includes giants, such as Facebook, YouTube, and Twitter. The Memcached site, itself, does a good job of describing Memcached as a “Free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.”
