Proof[edit]

Anybody can show me the proof of this theory/idea/comment? JiggySoo

No, because it's not a scientific fact (AFAIK). I created the stub because I found a reference for the term in an article about Computer Science history, and it was not easy to google for it. Diego 19:58, 12 June 2006 (UTC)[reply]

It's bogus btw, on a 1920x1200 screen (or even 2560x1600) you can have a hundred elements on your screen and still work with them. And Visual Programming uses the real estate more effectively than text languages. 78.94.236.40 (talk) 22:10, 27 February 2008 (UTC)[reply]

I guess the point is not about being able to technically display more thatn 50 elements, but rather to construct a viable graph, which remains quick to understand and be easily recognizable. At 50 elements, no matter the screen resolution, it becomes hard to grasp the flow of data and interpret in an instant. Textual languages don't demand that you fit the whole programm on one page of the screen, in this respect they suffer the same limits, but it is not expected of them to have the same quick understandability which may be demanded by visual programming languages. On the same thought, textual languages keep their overview by modularisation, which could of couse be applied to VPL as well. So, I don't think the Deutsch Limit describes the technical limit of only displaying 50 elements, but rather the cognitive-limit of only being able to grasp 50 elements in graph at a time.

Mechanically generated diagrams of graphs (eg, DOT diagrams from GraphViz) can become incomprehensible fairly quickly as the number of nodes increases. However, maps and circuit diagrams can be read even when there are far more elements than this. The difference may be that there is an organizing principle that the user shares with the author. Martin Krzywinski's Circos and Hive Plots add such an organizing principle to graph diagrams, with some success. RichMorin (talk) 15:11, 29 July 2012 (UTC)[reply]

What's a visual primitive?[edit]

? Peter Flass (talk) 14:44, 25 July 2012 (UTC)[reply]

Why, it's a primitive of a visual nature.
It refers to the number of items -language elements- that fit in the screen at the same time. Diego (talk) 15:19, 25 July 2012 (UTC)[reply]
Such as an icon or menu item? Peter Flass (talk) 20:09, 25 July 2012 (UTC)[reply]
No, more like boxes and arrows (think of transistors and resistors in an electronic circuit, but for programming functions - logic gates, math operations...). Icons and menus are widgets; not usually considered part of programming languages. Diego (talk) 22:01, 25 July 2012 (UTC)[reply]

Capitalization[edit]

The sources use "Deutsch Limit" as the proper capitalization, but User:Dicklyon moved it to the current title. I can't find anything in policy justifying that move, should we restore it to the original title that matches the available sources? Diego (talk) 16:28, 25 July 2012 (UTC)[reply]

Compare WP:CAPS, MOS:CAPS, and sources like this one and this one and this one. Dicklyon (talk) 00:39, 26 July 2012 (UTC)[reply]

Linus Torvalds on when functions get too big[edit]

"Functions should be short and sweet, and do just one thing. They should fit on one or two screenfuls of text (the ISO/ANSI screen size is 80×24, as we all know), and do one thing and do that well." is from the Linux Kernel Coding Style document. 2605:A601:46D:B01:CABC:C8FF:FEA5:82F4 (talk) 08:44, 11 August 2016 (UTC)[reply]
