I3 (window Manager)
i3 is a tiling window manager designed for X11, inspired by wmii and written in C. It supports tiling, stacking, and tabbing layouts, which it handles dynamically. Its configuration is achieved via a plain text file and extending i3 is possible using its Unix domain socket and JSON based IPC interface from many programming languages. Like wmii, i3 uses a control system very similar to that of vi and Vim. By default, window focus is controlled by what the documentation refers to as the 'Mod1' key (Alt key/Windows key) plus the right-hand home row keys (Mod1+J,K,L,Semicolon), while window movement is controlled by the addition of the Shift key (Mod1+Shift+J,K,L,Semicolon). Design goals i3's primary design goals are to possess well-written, documented code that encourages user contribution; to use XCB instead of Xlib; to implement multi-monitor features correctly, so that each workspace is assigned to a virtual screen, and monitor additions and removals are non-destructiv ...

Triiodide
In chemistry, triiodide usually refers to the triiodide ion, . This anion, one of the polyhalogen ions, is composed of three iodine atoms. It is formed by combining aqueous solutions of iodide salts and iodine. Some salts of the anion have been isolated, including thallium(I) triiodide (Tl+ 3sup>−) and ammonium triiodide ( H4sup>+ 3sup>−). Triiodide is observed to be a red colour in solution. Nomenclature Other chemical compounds with "triiodide" in their name may contain three iodide centers that are not bonded to each other as the triiodide ion, but exist instead as separate iodine atoms or iodide ions. Examples include nitrogen triiodide (NI3) and phosphorus triiodide (PI3), where individual iodine atoms are covalently bonded to a central atom. As some cations have the theoretical possibility to form compounds with both triiodide and iodide ions, such as ammonium, compounds containing iodide anions in a 3:1 stoichiometric ratio should only be referred to as triiodides ...

InterMUD
LPMud, abbreviated LP, is a family of MUD server software. Its first instance, the original LPMud game driver, was developed in 1989 by Lars Pensjö (hence the LP in LPMud). LPMud was innovative in its separation of the MUD infrastructure into a virtual machine (known as the driver) and a development framework written in the LPC programming language (known as the mudlib). Motivation Pensjö had been an avid player of TinyMUD and AberMUD. He wanted to create a world with the flexibility of TinyMUD and the style of AberMUD. Furthermore, he did not want to have sole responsibility for creating and maintaining the game world. He once said, "I didn't think I would be able to design a good adventure. By allowing wizards coding rights, I thought others could help me with this." The result was the creation of a new, C-based, object-oriented programming language, LPC, that made it simple for people with minimal programming skills to add elements like rooms, weapons, and monsters to a v ...

Rank-into-rank
In set theory, a branch of mathematics, a rank-into-rank embedding is a large cardinal property defined by one of the following four axioms given in order of increasing consistency strength. (A set of rank < λ is one of the elements of the set Vλ of the .) *Axiom I3: There is a nontrivial of Vλ into itself. *Axiom I2: There is a nontrivial elementary embedding of V into a transitive class M that includes Vλ where λ is the first fixed point above the critical point. *Axiom I1: There is a nontrivial elementary embedd ...

Interstate 3
Interstate 3 (I-3), the 3rd Infantry Division Highway, is a proposed Interstate Highway in the United States to run from Savannah, Georgia, north to Augusta, Georgia, and Knoxville, Tennessee. The roadway was proposed in the same federal highway measure that gave birth to a proposal for I-14. History In 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) was signed into law by then-President George W. Bush. The act included the proposed corridors for the planned I-14 (specifically as the 14th Amendment Highway), and I-3 (as the 3rd Infantry Division Highway). The legislation did not provide the official numbering, nor did it provide funding for the highways. The proposed numbering of the highway does not follow the pattern of the existing Interstate Highway grid but is noted to salute and honor the Third Infantry Division of the United States Army, based at Fort Stewart, near Savannah, Georgia.

Inline-triple Engine
A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engines, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural machinery. Design A crankshaft angle of 120 degrees is typically used by straight-three engines, since this results in an evenly spaced firing interval. Another benefit of this configuration is perfect primary balance and secondary balance, however an end-to-end rocking couple is induced because there is no symmetry in the piston velocities about the middle piston. A balance shaft is sometimes used to reduce the vibrations caused by the rocking couple. Other crankshaft angles have been used occasionally. The 1976-1981 Laverda Jota motorcycle used a 180 degree crankshaft, where the outer pistons rise and fall together and inner cylinder is offset from them by 180 degrees. T ...

LB&SCR I3 Class
The LB&SCR I3 class was a class of 4-4-2 steam tank locomotives designed by D. E. Marsh for suburban passenger service on the London, Brighton and South Coast Railway. History After introducing two unsuccessful designs of 4-4-2 tank locomotive with the I1 and I2 classes, Douglas Earle Marsh learned a lesson and provided a new design with a far larger firebox.The new design was a tank version of Robert Billinton's successful B4 class tender locomotives. At the time of its introduction locomotive engineers were beginning to take an interest in superheating and Marsh therefore ordered two locomotives from Brighton railway works for comparative purposes, one with a traditional saturated boiler and one incorporating the Schmidt superheater. These were built in October 1907 and March 1908 respectively. Several months of trials proved that both locomotives were performing well and reliably, but the LB&SCR Board of Directors were still not convinced that the extra building costs ...

Type J1 Submarine
The , also called were large cruiser submarines (Junsen type submarines) of the Imperial Japanese Navy. Four boats were built between 1926 and 1929. These boats, based on the KD2 and U-139 designs, were of a junsen, or cruiser, type with an impressive range of 24,000 nm. Elderly by 1941 they were among the first Japanese submarines converted to supply duty. * was present during the attack on Pearl Harbor and witnessed the Doolittle raid on Tokyo, before patrolling the Aleutians. Her aft 14 cm gun was then removed to make room for a daihatsu cargo barge and she started shifting supplies in the Solomon Islands. On 29 January 1943, the New Zealand naval trawlers, ''Kiwi'' and ''Moa'' rammed and wrecked her in shallow water at Kamimbo Bay, Guadalcanal. Critical codes remained on board and the Japanese command tried unsuccessfully to destroy the boat with submarine and airplane attacks. The US Navy salvaged 200,000 pages of intelligence: code books, charts, manuals, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I3 Fighter
The i3 Fighter is a conceptual jet fighter proposed by the Ministry of Defense (Japan), Ministry of Defense of Japan in 2010 in association with development of the successor to the Mitsubishi F-2 fighter. The i3 stands for Informed, Intelligent and Instantaneous. Overview With modernization and expansion of the People's Liberation Army Air Force and Russian Aerospace Forces accelerating, the Japan Air Self-Defense Force (JASDF) envisaged a mass deployment of Chinese as well as Russian 4.5th and Fifth-generation jet fighter, 5th generation fighters in the region in the near future, and, in 2010, issued a report to call for development of a new generation high performance fighter to compensate for numerical inferiority and secure air superiority in such an environment. The report, ''A vision for research and development of future fighter'', stressed the importance of indigenous development to maintain domestic fighter manufacturing base, and proposed a counter-stealth fighter capab ...

Mikoyan-Gurevich I-3
The Mikoyan-Gurevich I-3 was the first of three interrelated fighter prototype programs developed by the Mikoyan-Gurevich design bureau in the Soviet Union in the mid/late 1950s – starting with the I-3, continuing with the I-7 and finally evolving into the I-75. On several occasions airframes were rebuilt and/or reused, both within a program or in a succeeding program. All the aircraft in the I-3 program were affected by delays in the development of the Klimov VK-3 afterburning bypass turbojet engine, and its cancellation and replacement by the Lyulka AL-7F turbojet engine. Design and development Both the I-3 and I-3P were ordered by the Council of Ministers on June 3, 1953 – the I-3 as a frontline fighter and the I-3P as an all-weather interceptor. They were developed in parallel with the I-1/2 program but had nothing in common with it except a similar wing. On the other hand, the I-3's visual appearance was so similar to the Sukhoi S-1 (the Su-7 prototype) that a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
