Function, Functionality, Functionalism
The requirements of economy
Useless work on useful things
The minimum condition
Form eschews function
Feeble and ugly
Functionalism can be a kind of religion
Each element performs many functions
The informing idea of functionalism
Same name in the same basket
The plan must anticipate all that is needed
The element becomes a sign
Classical absurdity

Roaming and capricious
What are those borders made of?
Presentable
A strangely negative character
Sine qua non
The contribution that something in them yet compelled them to make
Something more is required

Embracing design constraints
An Article by Adrian RoselliConstraints have been shown to generally improve innovation. Giving targets and parameters helps ensure a team is working in unison. Identifying what is out of bounds can further focus that team.
A Plea for Lean Software
An Essay by Niklaus WirthSoftware's girth has surpassed its functionality, largely because hardware advances make this possible. The way to streamline software lies in disciplined methodologies and a return to the essentials.
Beauty in flight

A Plea for Lean Software
Software's girth has surpassed its functionality, largely because hardware advances make this possible. The way to streamline software lies in disciplined methodologies and a return to the essentials.
Measured by the number of its features
A primary cause of complexity is that software vendors uncritically adopt almost any feature that users want. Any incompatibility with the original system concept is either ignored or passes unrecognized, which renders the design more complicated and its use more cumbersome. When a system's power is measured by the number of its features, quantity becomes more important than quality. Every new release must offer additional features, even if some don't add functionality.
Essential vs. nice to have
Customers have trouble distinguishing between essential features and those that are just "nice to have." Examples of the latter class: those arbitrarily overlapping windows suggested by the uncritically but widely adopted desktop metaphor; and fancy icons decorating the screen display, such as antique mailboxes and garbage cans that are further enhanced by the visible movement of selected items toward their ultimate destination. These details are cute but not essential, and they have a hidden cost.

Increased complexity results in large part from our recent penchant for friendly user interaction. I've already mentioned windows and icons; color, gray-scales, shadows, pop-ups, pictures, and all kinds of gadgets can easily be added.
Dependence is more profitable than education
A customer who pays—in advance—for service contracts is a more stable income source than a customer who has fully mastered a product's use.
Customer dependence is more profitable than customer education.
What I find truly baffling are manuals—hundreds of pages long—that accompany software applications, programming languages, and operating systems. Unmistakably, they signal both a contorted design that lacks clear concepts and an intent to hook customers.
The most rewarding iterations
Initial designs for sophisticated software applications are invariably complicated, even when developed by competent engineers. Truly good solutions emerge after iterative improvements or after redesigns that exploit new insights, and the most rewarding iterations are those that result in program simplifications.
Evolutions of this kind, however, are extremely rare in current software practice—they require time-consuming thought processes that are rarely rewarded. Instead, software inadequacies are typically corrected by quickly conceived additions that invariably result in the well-known bulk.
Never enough time
Time pressure is probably the foremost reason behind the emergence of bulky software. The time pressure that designers endure discourages careful planning. It also discourages improving acceptable solutions; instead, it encourages quickly conceived software additions and corrections. Time pressure gradually corrupts an engineer's standard of quality and perfection. It has a detrimental effect on people as well as products.
