In computing, minimalism refers to the application of minimalist philosophies and principles in hardware and software design and usage.

History

In the late 1970s and early 1980s programmers had to work within the confines of relatively expensive and limited resources. 8 or 16 kilobytes of RAM was common; 64 kilobytes was considered a vast amount and was the entire address space accessible to the 8-bit CPUs predominant during the earliest generations of personal computers. The most common storage medium was the 5.25 inch floppy disk holding from 88 to 170kB. Hard drives with capacities from 5 to 10 megabytes cost thousands of dollars.

Over time, personal computer memory capacities expanded by orders of magnitude and mainstream programmers took advantage of the added storage to increase their software's capabilities and/or to make development easier by using higher-level languages. By contrast, system requirements for legacy software remained the same. As a result, even the most elaborate, feature-rich programs of yesteryear seem minimalist in comparison with current software. Many of these programs are now considered abandonware. One example of a program whose system requirements once gave it a heavyweight reputation is the GNU Emacs text editor, which gained the backronym "Eight Megabytes And Constantly Swapping" in an era when 8MB was a lot of RAM,[1] but today its mainly textual buffer-based paradigm uses far less resources than desktop metaphor GUI IDEs with comparable features such as Eclipse or Netbeans.[2] In a speech at the 2002 International Lisp Conference, Richard Stallman indicated that minimalism was a concern in his development of GNU and Emacs, based on his experiences with Lisp and system specifications of low-end minicomputers at the time.[3]

As the capabilities and system requirements of common desktop software and operating systems grew throughout the 1980s and 1990s, and as software development became dominated by teams espousing conflicting, faddish software development methodologies, some developers adopted minimalism as a philosophy and chose to limit their programs to a predetermined size or scope.[4] A focus on software optimization can result in minimalist software, as programmers reduce the number of operations their program carries out in order to speed execution.[5]

In the early 21st century, new developments in computing devices have brought minimalism to the forefront. In what has been termed the post-PC era it is no longer necessary to buy a high-end personal computer merely to perform common computing tasks.[6] Mobile computing devices, such as smartphones, tablet computers, netbooks and plug computers, often have smaller memory capacities, less-capable graphics subsystems, and slower processors when compared to the personal computer they are expected to replace. In addition, heavy use of graphics effects like alpha blending drains the battery on these devices faster than a "flat ui".[7] The growing popularity of these stripped-down devices has made minimalism an important design concern. Google's Chrome browser and Chrome OS are often cited as examples of minimalist design.[8][9] In Windows 8, Microsoft has decided to drop the graphics-intensive Aero user interface in favor of the "simple, squared-off" Metro appearance, which requires less system resources. This change was made in part because of the rise of smaller, battery-powered devices and the need to conserve power.[10][11][12] Version 7 of Apple's iOS makes similar changes for user experience reasons.[13]

Usage

Developers may create user interfaces made to be as simple as possible by eliminating buttons and dialog boxes that may potentially confuse the user. Minimalism is sometimes used in its visual arts meaning, particularly in the industrial design of the hardware device or software theme.

Some developers have attempted to create programs to perform a particular function in the fewest lines of code, or smallest compiled executable size possible on a given platform.[14][15] Some Linux distributions mention minimalism as a goal. Arch Linux, Puppy Linux, Bodhi Linux, CrunchBang Linux, dynebolic[16] and Damn Small Linux are examples. The early development of the Unix system occurred on low-powered hardware, and Dennis Ritchie and Ken Thompson have stated their opinion that this constraint contributed to the system's "elegance of design".[17]

Programming language designers can create minimal programming languages by eschewing syntactic sugar and extensive library functions. Such languages may be Turing tarpits due to not offering standard support for common programming tasks. Creating a minimal Lisp interpreter is a common learning task set before programming students.[18] The Lambda calculus, developed by Alonzo Church defines the most minimal programming language.[19][20] Scheme,[21][22] Forth,[23] and Go[24][25] are cited as examples of minimal programming languages.

The programming hobby of code golf results in minimalist software,[26] but these are typically exercises or code poetry, not usable applications software.

John Millar Carroll, in his book Minimalism Beyond the Nürnberg Funnel pointed out that the use of minimalism results in "instant-use" devices such as video games, ATMs, voting machines, and mall kiosks with little-or-no learning curve that do not require the user to read manuals.[27] User Interface researchers have performed experiments suggesting that minimalism, as illustrated by the design principles of parsimony and transparency, bolsters efficiency and learnability.[28] Minimalism is implicit in the Unix philosophies of "everything is a text stream" and "do one thing and do it well".[29]
