This payload was de-minified and commented with the technical explanations of it's function.

Further details on the technical aspects of the script have been posted, as the developer of the exploit has posted "minified" version of the exploit payload.

In programmer culture, aiming at extremely minified source code is the purpose of recreational code golf competitions. Minification can be distinguished from the more general concept of data compression in that the minified source can be interpreted immediately without the need for an uncompression step: the same interpreter can work with both the original as well as with the minified source. The goals of minification are not the same as the goals of obfuscation; the former is often intended to be reversed using a pretty-printer or unminifier. However, to achieve its goals, minification sometimes uses techniques also used by obfuscation; for example, shortening variable names and refactoring the source code.

Source maps allow tools to display unminified code from minified code with an optimized "mapping" between them. The original format was created by Joseph Schorr as part of the Closure Inspector minification project. Updates as versions 2 and 3 reduced the size of the map files.

XPages also give the application new capabilities that are not possible with the classic IBM Notes client. The IBM Domino 9 Social Edition included the IBM Notes Browser Plugin, which would surface Notes applications through a minified version of the rich desktop client contained in a browser tab.

When used for minification it is often used with mipmapping; though it can be used without, it would suffer the same aliasing and shimmering problems as nearest-neighbor filtering when minified too much. For modest minification ratios, however, it can be used as an inexpensive hardware accelerated weighted texture supersample.

According to a Fog Creek blog post in January 2012, the client was an extremely thin web layer which downloads the main app, written in CoffeeScript and compiled to minified JavaScript, using Backbone.js HTML5 `.pushState()` and the Mustache templating language. The server side was built on top of MongoDB, Node.

T7 RNA polymerase producing a mRNA (green) from a DNA template. The protein is shown as a purple ribbon. Image derived from PDB 1MSW Orthopoxviruses and some other nucleocytoplasmic large DNA viruses synthesize RNA using a virally encoded multi-subunit RNAP. They are most similar to eukaryotic RNAPs, with some subunits minified or removed.

The YUI Core is a light (31KB minified) set of tools for event management and DOM manipulation. ;YUI Global Object : The YUI Global Object contains language utilities, a script loader, and other baseline infrastructure for YUI. ;Dom Collection : Helps with common DOM scripting tasks, including element positioning and CSS style management. ;Event Utility : Provides developers with easy and safe access to browser events (such as mouse clicks and key presses).

Firebug 2.0 introduced many new features to the Firebug extension including JavaScript syntax highlighting, pretty print for minified JavaScript code, and a DOM Event Inspector to handle all event handlers on a web page. Additionally, users can search for page elements using CSS selectors in the search bar. The debugging tool now allows users to inspect JavaScript expressions as they are evaluated. Moreover, users can inspect values returned from JavaScript functions.

Knapp's Rule states that lenses placed at the anterior focal point of the eye, generally 15 mm in front of the eye, will create similarly sized images on the retina, whenever the disparity between the two eyes is due to a difference in axial length of the eyes. When a refractive error is corrected with spectacle lenses, the retinal images change size. It is magnified with convex lenses and minified with concave lenses. One difficulty, then, in prescribing glasses to an individual with a disparity in refractive error between the two eyes is that a disparity in image size between the two eyes may be created.

Transcompilers may either keep translated code structure as close to the source code as possible to ease development and debugging of the original source code, or may change the structure of the original code so much that the translated code does not look like the source code. There are also debugging utilities that map the transcompiled source code back to the original code; for example, the JavaScript Source Map standard allows mapping of the JavaScript code executed by a web browser back to the original source when the JavaScript code was, for example, minified or produced by a transcompiled-to-JavaScript language. Examples include Closure Compiler, CoffeeScript, Dart, Haxe, TypeScript and Emscripten.

However, minification is not necessarily convenient nor efficient and may still require separate HTTP connections to get the page and the minified resources. HTTP/2 allows the server to "push" content, that is, to respond with data for more queries than the client requested. This allows the server to supply data it knows a web browser will need to render a web page, without waiting for the browser to examine the first response, and without the overhead of an additional request cycle. Additional performance improvements in the first draft of HTTP/2 (which was a copy of SPDY) come from multiplexing of requests and responses to avoid some of the head-of-line blocking problem in HTTP 1 (even when HTTP pipelining is used), header compression, and prioritization of requests.
