Happy Hacking Keyboard
The Happy Hacking Keyboard is a small computer keyboard produced by PFU Limited of Japan, codeveloped with Japanese computer scientist and pioneer Eiiti Wada. Its reduction of keys from the common 104-key layout down to 60 keys in the professional series is the basis for its smaller size while retaining full key size. It returns the control key to its original position as on the early 84-key IBM Personal Computer/AT and XT layouts. The current models in production are the Happy Hacking Keyboard Professional Classic, Professional Hybrid (wired/wireless dual connectivity), and Professional Hybrid Type-S (silenced variant of Hybrid) all in either dark or light colorways, and either blank or printed keycaps. Professional Hybrid models are also available in Japanese layout. History Beginnings Frustrated that each new computer system came with a new keyboard layout that became increasingly complex, Wada sought to create his own keyboard that he could continue to use with vario ...

Happy Hacking Keyboard Lite 2
Happiness, in the context of mental or emotional states, is positive or pleasant emotions ranging from contentment to intense joy. Other forms include life satisfaction, well-being, subjective well-being, flourishing and eudaimonia. Since the 1960s, happiness research has been conducted in a wide variety of scientific disciplines, including gerontology, social psychology and positive psychology, clinical and medical research and happiness economics. Definitions "Happiness" is subject to debate on usage and meaning, and on possible differences in understanding by culture. The word is mostly used in relation to two factors: * the current experience of the feeling of an emotion (affect) such as pleasure or joy, or of a more general sense of 'emotional condition as a whole'. For instance Daniel Kahneman has defined happiness as "''what I experience here and now''". This usage is prevalent in dictionary definitions of happiness. * appraisal of life satisfaction, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 216
ISO 216 is an international standard for paper sizes, used around the world except in North America and parts of Latin America. The standard defines the "A", "B" and "C" series of paper sizes, including A4, the most commonly available paper size worldwide. Two supplementary standards, ISO 217 and ISO 269, define related paper sizes; the ISO 269 "C" series is commonly listed alongside the A and B sizes. All ISO 216, ISO 217 and ISO 269 paper sizes (except some envelopes) have the same aspect ratio, , within rounding to millimetres. This ratio has the unique property that when cut or folded in half widthways, the halves also have the same aspect ratio. Each ISO paper size is one half of the area of the next larger size in the same series. Dimensions of A, B and C series History The oldest known mention of the advantages of basing a paper size on an aspect ratio of is found in a letter written on 25 October 1786 by the German scientist Georg Christoph Lichtenbe ...

DIP Switch
A DIP switch is a manual electric switch that is packaged with others in a group in a standard dual in-line package (DIP). The term may refer to each individual switch, or to the unit as a whole. This type of switch is designed to be used on a printed circuit board along with other electronics, electronic components and is commonly used to customize the behavior of an electronic device for specific situations. DIP switches are an alternative to jumper (computing), jumper blocks. Their main advantages are that they are quicker to change and there are no parts to lose. History US patent 3,621,157 is the earliest known DIP switch patent. The patent discloses a rotary style DIP switch invented by Pierre P. Schwab. Schwab's patent application was filed on June 1, 1970, and the patent was granted on November 16, 1971. The DIP switch with sliding levers was granted US patent 4012608 in 1976. It was applied for 1974 and was used in 1977 in an ATARI Flipper game. Types The slide, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alt Key
The Alt key (pronounced or ) on a computer keyboard is used to change (alternate) the function of other pressed keys. Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. For example, simply pressing ''A'' will type the letter 'a', but holding down the Alt key while pressing ''A'' will cause the computer to perform an function, which varies from program to program. The international standard ISO/IEC 9995-2 calls it ''Alternate key''. The key is located on either side of the space bar, but in non-US PC keyboard layouts, rather than a second Alt key, there is an ' Alt Gr' key to the right of the space bar. Both placements are in accordance with ISO/IEC 9995-2. With some keyboard mappings (such as US-International), the right Alt key can be reconfigured to function as an AltGr key although not engraved as such. The standardized keyboard symbol for the Alt key, (which may be used when the usual Latin lettering “Alt” is not preferred for la ...

Space Bar
The space bar is on the bottom center of the keyboard The space bar, spacebar, blank, or space key is a key on a typewriter or alphanumeric keyboard in the form of a horizontal bar in the lowermost row, significantly wider than all other keys. Its main purpose is to conveniently enter a space, e.g., between words during typing. History Originally, (on early writers dating back to the late 19th century) the "bar" was literally a metal bar running across the full width of the keyboard (or even wider, and even surrounding it) that triggered the carriage advance without also firing any of the typebars towards the platen. Later examples gradually shrank and developed into their current more ergonomic form as a wide, centrally located but otherwise apparently normal "key", as typewriter (and computer) keyboards began to incorporate additional function keys and were more deliberately "styled". Although it varies by keyboard type, the space bar usually lies between the Alt keys (or Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meta Key
The Meta key is a modifier key on certain keyboards. It first appeared on the Stanford Artificial Intelligence Lab (SAIL) keyboard in 1970. History The Meta key first appeared on the Stanford Artificial Intelligence Lab (SAIL) keyboard in 1970 and successors such as the Knight keyboard, space-cadet keyboard, MIT Lisp machine, Symbolics keyboards, and on Sun Microsystems keyboards (where it is marked with a black diamond "◆"). Use Generally, the Meta key worked similar to Macintosh's Command key, in that when held down it modified letters and symbols into immediate commands (shortcuts). On these keyboards the Control key was placed closest to the space bar, then the Meta key outside Control. The space-cadet keyboard added the Super key outside Meta, and the Hyper key outside that. All these keys produced shortcuts (24 of them for every letter), but the Control ones were easiest to type and most popular, and the Meta ones second-easiest and thus second most popular. H ...

Backspace
Backspace () is the keyboard key that originally pushed the typewriter carriage one position backwards and in modern computer systems moves the display cursor one position backwards,"Backwards" means to the left for left-to-right languages. deletes the character at that position, and shifts back the text after that position by one position. Typewriter In someMany typewriters don't advance accent characters, so that no backspace is needed. However, it is still used e.g. for combining "o" with "/". typewriters, a typist would, for example, type a lowercase letter A with acute accent (á) by typing a lowercase letter A, backspace, and then the acute accent key. This technique (also known as overstrike) is the basis for such spacing modifiers in computer character sets such as the ASCII caret (^, for the circumflex accent). Backspace composition no longer works with typical modern digital displays or typesetting systems.There is no reason why a digital display or typesetting system ...

Enter Key
On computer keyboards, the enter key and return key are two closely related keys with overlapping and distinct functions dependent on operating system and application. Functions The return key has its origins in two typewriter functions: carriage return, which would reset the carriage to the beginning of the line of text, and line feed, which would advance the paper one line downward. These were often combined into a single return key, a convention that continues in modern computer word processing to insert a paragraph break (¶). The enter key is a computer innovation, which in most cases causes a command line, window form, or dialog box to operate its default function. This is typically to finish an "entry" and begin the desired process, and is usually an alternative to clicking an OK button. Additionally, it can act as the ''equal to'' button in calculator programs. On modern computers both keys generally have all the functions of the other, allowing for either key to b ...

Delete Key
The delete key is a key on most computer keyboards which is typically used to delete either (in text mode) the character ahead of or beneath the cursor, or (in GUI mode) the currently-selected object. The key is sometimes referred to as the "forward delete" key. This is because the backspace key also deletes characters, but to the left of the cursor. On many keyboards, such as most Apple keyboards, the key with the backspace function is also labelled "delete". Position and labeling on keyboards The key appears on English-language IBM-compatible PC keyboards labeled as or , sometimes accompanied by a crossed-out right-arrow symbol. A dedicated symbol for "delete" exists as U+2326 ⌦ but its use as a keyboard label is not universal. However, sometimes the key labelled performs the Backspace function instead, for example on some Apple keyboards. In other cases, the Delete key is in its original IBM notebook position of above and to the right of the Backspace key. Many lapt ...

Esc Key
On computer keyboards, the Esc key (named ''Escape key'' in the international standard series ISO/IEC 9995) is a key used to generate the escape character (which can be represented as ASCII code 27 in decimal, Unicode U+001B, or ). The escape character, when sent from the keyboard to a computer, often is interpreted by software as "stop", and when sent from the computer to an external device (including many printers since the 1980s, computer terminals and Linux consoles, for example) marks the beginning of an escape sequence to specify operating modes or characteristics generally. It is now generally placed at the top left corner of the keyboard, a convention dating at least to the original IBM PC keyboard, though the key itself originated decades earlier with teletypewriters. Symbol The keyboard symbol for the ESC key (which may be used when the usual Latin lettering "Esc" is not preferred for labelling the key) is standardized in ISO/IEC 9995-7 as symbol 29, and ...
