Allen-Babcock. Allen-Babcock Computing was founded in Los Angeles in 1964 by James D. Babcock and Michael Jane Allen Babcock to take advantage of the fast-growing market for computer time-sharing services.

In 1966 the company developed "RUSH" (Remote Users of Shared Hardware), an interactive dialect of PL/I.
Between 1965 and 1966 they assisted in the development of Conversational Programming System (CPS), a timesharing system that ran under OS/360, under contract to IBM. 
CPS  was a subset of RUSH prepared by IBM with the permission of Allen-Babcock.

The significant technological outcome was the first idea to alter the hardware of an IBM computer to enhance the performance of a time-sharing system on IBM hardware. This was the first time such firmware was programmed by software developers for this purpose. Later tests showed increases of throughput by as much as 70%. Several such altered 360 Model 50s were delivered to other IBM customers.

In 1969 Allen-Babcock held a 3 percent share of the time-sharing services market.

During the early 70's Allen-Babcock leased copies of the RUSH software to several industry owners of the IBM 360 series computer systems. One such company was Procter & Gamble. These lessees sought to use RUSH internally to provide their companies access to time sharing on their Internet networks.

In 1975 Allen-Babcock was acquired by Tymshare.

AiLive. AiLive Inc. (formerly iKuni) is a software company based in Mountain View, California, United States. The company was co-founded in 2000 by software programmer and developer Wei Yen and by computer engineer Xiaoyuan Tu. The company has worked closely with Nintendo on the development of motion-sensing hardware, tools and software for the Wii video game console.

AiLive is responsible for the LiveMove series of products. The system was introduced in 2006, using machine learning technology to facilitate the development of motion recognition packages for individual games. Developers were able to use the software to build classifiers from provided examples of specific motions to be included in each game. The LiveMove system was used for the development of games for the Wii. Though initially released for professional developers of Wii games, the software was designed for use by independent developers as well, to expand the possibilities of the new console and Wii Remote interface.

Wii MotionPlus

AiLive developed the Wii MotionPlus.
The device added short-term 3D position tracking and long-term 3D orientation tracking to the Wii Remote motion controller. Initially provided as a dongle, the technology has since been integrated into all new Wii Remote controllers carrying the logo Wii MotionPlus Inside. The Wii MotionPlus was initially shipped in a bundle with Wii Sports Resort. Nintendo shipped more than 29 million units globally, making it the sixth best-selling game of all time. In addition to the Wii MotionPlus device concept, AiLive developed and patented the motion tracking algorithms for the device and made them available to developers through the LiveMove 2 software.

LiveMove 2
A new version of the software, LiveMove 2, was announced on July 7, 2008. Similar to the previous version, LiveMove 2 was developed specifically to work with Nintendo hardware. In this case, the software is a development tool for use with the Wii MotionPlus attachment that AiLive had codeveloped. On June 2, 2009, following the unveiling of PlayStation Move at Electronic Entertainment Expo 2009, AiLive announced the release of LiveMove 2 for PlayStation 3. Through a partnership between AiLive and Sony, the LiveMove 2 software was made available to all registered PlayStation 3 developers.

DRG Class 71.0. The German DRG Class 71.0 was a  locomotive with the Deutsche Reichsbahn, which was intended as a replacement for railbuses. Originally it had been planned for these standard engines (Einheitsloks) to haul fast passenger trains.

Two vehicles were delivered in 1934 by the firm of Schwartzkopff and two each in 1936 by the firms of Borsig and Krupp. The two-cylinder superheated engines were equipped with automatic underfeed stokers for one-man operation. In the course of its service the boiler overpressure was reduced from 20 bar to 16 bar for safety reasons. All the locomotives had a plate frame. The second coupled wheelset was driven and the carrying wheels rested in Bissel axles.

The Deutsche Bundesbahn took over all the engines after the Second World War and allocated them to the locomotive depot (Bahnbetriebswerk or Bw) in Nuremberg. Later they were all transferred to Kaiserslautern and Landau. The locomotives were retired by 1956.

No examples of the DRG Class 71.0 remain.

DRG Class 43. The German locomotives of DRG Class 43 were standard (see Einheitsdampflokomotive) goods train engines with the Deutsche Reichsbahn.

History 
This was the second class that was built on the Einheitslok principle. According to the first classification scheme of the DR's Standardisation Bureau, 2-10-0 goods train locomotives were to be procured with a 20-ton axle load. To achieve this a two-cylinder class (the Class 43) and a three-cylinder class (the Class 44) were envisaged, because it was not yet known which configuration would be more economical. Ten examples of each class were procured in parallel. The Class 43 was supplied by Henschel and by Schwartzkopff.

In trials it was discovered that the Class 43 was more economical to operate at powers under 1500 PSi. As a result, a further 25 examples of the 43 were ordered up to 1928. However, due to the increase in goods train speeds in the 1930s, the Class 44 was given priority thereafter because, in addition to its economy when running at higher speeds and the better running qualities of its three-cylinder driving gear, it was also cleared for running at up to 80 km/h. As a result, no more Class 43s were ordered.

In the literature statements are often found that the locomotive was not sufficiently powerful overall. In response to that, number 43 013 was loaded for testing purposes with a train of 5000 tons – that is more than twice that given in the haulage tables – and headed it without complaint. In doing so, 43 013 is a record holder. Never before or since has any German locomotive hauled such a load.

The Class 43s, which had operating numbers 43 001 – 43 035, all remained with the DR in East Germany after the Second World War. In 1960, the remaining engines were once again modernised, the powerful boiler even enabled goods trains greater than the maximum allowable load to be hauled. This led, however, to frame damage, that the Reichsbahn could not repair. So the machines were rapidly retired, the last one being taken out of service in 1968 at Cottbus locomotive depot. Locomotive 43 001 became a museum locomotive and belongs to the Dresden Transport Museum, but is in the Saxon Railway Museum, a former home depot of the Class 43.

The engines of this class were equipped with a 22 T 32 tender.

Degenerate semiconductor. A degenerate semiconductor is a semiconductor with such a high level of doping that the material starts to act more like a metal than a semiconductor. Unlike non-degenerate semiconductors, these kinds of semiconductor do not obey the law of mass action, which relates intrinsic carrier concentration with temperature and bandgap.

At moderate doping levels, the dopant atoms create individual doping levels that can often be considered as localized states that can donate electrons or holes by thermal promotion (or an optical transition) to the conduction or valence bands respectively. At high enough impurity concentrations, the individual impurity atoms may become close enough neighbors that their doping levels merge into an impurity band and the behavior of such a system ceases to show the typical traits of a semiconductor, e.g. its increase in conductivity with temperature. On the other hand, a degenerate semiconductor still has far fewer charge carriers than a true metal so that its behavior is in many ways intermediary between semiconductor and metal.

Many copper chalcogenides are degenerate p-type semiconductors with relatively large numbers of holes in their valence band. An example is the system LaCuOS1−xSex with Mg doping. It is a wide gap p-type degenerate semiconductor. The hole concentration does not change with temperature, a typical trait of degenerate semiconductors.

Another well known example is indium tin oxide. Because its plasma frequency is in the IR-range, it is a fairly good metallic conductor, but transparent in the visible range of the spectrum.

MightySat-1. MightySat-1 was a small spacecraft developed by the U.S. Air Force's Phillips Laboratory (now part of the Air Force Research Laboratory Space Vehicles Directorate) to test technology for small satellites, including advanced dual-junction solar cells, a composite structure, a micrometeorite and debris detector, low-power electronics and a low-shock release device. The 140-pound satellite was launched from the Space Shuttle Endeavour in December 1998, during the 12th day of the STS-88 mission and performed robustly in orbit, with no spacecraft anomalies during its mission. Lt. Barbara Braun of the AFRL was the program manager for the satellite.

MightySat-1's mission ended when it re-entered the atmosphere at 17:11 UTC on November 21, 1999.

Ririe Reservoir. The Ririe Reservoir is a reservoir located near Ririe, Idaho.  It allows for irrigation, flood control, and provides recreational opportunities.

In 1972 the Ririe Dam, built on Willow Creek by the United States Army Corps of Engineers, was the site of the first practical application of steel fibrous shotcrete, which was used to build a tunnel adit.  The dam's total capacity is more than 100,000 acre-feet of water.  On October 14, 1976, the Corps of Engineers formally transferred control of the dam to the United States Bureau of Reclamation.

Ecology
The area surrounding the dam is hilly shrub-stepped and features the sagebrush and bunch grass typical of the area.  The reservoir itself contains rainbow trout, kokanee salmon, cutthroat trout, smallmouth bass, and yellow perch.

Possibility of failure
If the Ririe Dam failed catastrophically, either from a natural disaster or a human initiated event, it would reach the first population center, the City of Ucon, in 108 minutes; it would reach the City of Idaho Falls, the major population center of Bonneville County, in 187 minutes. The Dam is not staffed 24 hours a day and therefore, it is anticipated that there would be at least a fifteen (15) minute lag between event initiation and the commencement of the notification to residents.

AMD CodeAnalyst. AMD CodeAnalyst is a GUI-based code profiler for x86 and x86-64-based machines. CodeAnalyst has similar look and feel on both Linux and Microsoft Windows platforms. CodeAnalyst uses specific hardware profiling techniques which are designed to work with AMD processors, as well as a timer-based profiling technique which does not require specific hardware support; this allows a subset of profiling features to work on non-AMD processors, such as Intel processors.

As of March 2013, CodeAnalyst has been replaced by AMD CodeXL.

Code optimization
CodeAnalyst is built on OProfile for the Linux platform and is available as a free download. The GUI assists in various kinds of code profiling including time based profiling, hardware event-based profiling, instruction-based profiling and others. This produces statistics about details such as time spent in each subroutine which can be drilled down to the source code or instruction level. The time taken by the instructions can be indicative of stalls in the pipeline during instruction execution. Optimization could be as simple as reordering the instructions for maximum utilization of a data line cache or altering/removing the branches and loops so that the maximum number of execution units(Load/Store units, ALU, FP execution unit...) are utilized in parallel.

Support for PERF was added in CodeAnalyst 3.4, allowing users to choose between OProfile and PERF as the profiling backend.

Instruction-Based Sampling
CodeAnalyst supports IBS (Instruction-Based Sampling) that was introduced in Family 10h AMD processors (Barcelona). With IBS support, CodeAnalyst can more precisely identify instructions that cause pipeline stalls and cache misses.

Open-source
The Linux version of CodeAnalyst is available under GNU General Public License 2.0.

CodeAnalyst also uses other open-source components, including the Qt framework, libdwarf, libelf, and the Binary File Descriptor library.

John Linsley Hood. John Laurence Linsley-Hood (9 February 1925 in Wandsworth, London – 11 March 2004 in Taunton, Somerset) was an English electronics engineer and designer of audio components.

He was educated at Reading School, Acton Polytechnic, the Royal Technical College (Glasgow) and after World War Two, at Reading University. In 1942 Linsley-Hood joined the G.E.C. Research Laboratories at Wembley, working on magnetron development as junior member of a team. Joining the RAF aircrew in 1943, he was transferred to work on radar, then subsequently worked with T.R.E. (Malvern) overseas. After returning to university, Linsley-Hood joined the Windscale Research Laboratories of the Atomic Energy Authority. He was in charge of the electronics team in the Research Laboratories of British Cellophane Ltd. from 1954.

John Linsley-Hood is best remembered by hi-fi enthusiasts for his "Simple Class A Amplifier", which he developed to provide a good-quality performance comparable to that of the classic Williamson amplifier. The design was published in Wireless World in 1969 (April 1969 issue, p. 148), and later updated in 1996.

Linsley-Hood wrote for a number of magazines and published books on schematics for audio components, including:

 The Art of Linear Electronics (Oxford, Butterworth-Heinemann, 1993)

Mojave Experiment. The Mojave Experiment was an advertising campaign conducted by Microsoft for Windows Vista in 2008. The campaign was part of Microsoft's efforts to change what it felt was an unfair negative consumer perception of the operating system. Mojave spanned a series of advertisements that consisted of individuals being shown a demonstration of Windows Vista by Microsoft; however, the operating system was rebranded in disguise as a new version of Windows codenamed "Mojave," which was not revealed during the demonstration. 

Prior to the demonstration, participants generally gave a negative assessment of Windows Vista. In contrast, reviews for "Mojave" were positive, with participants stating that they intended to use or purchase the operating system for themselves; the same participants were astonished when they were told that "Mojave" was Windows Vista. The campaign implied that negative consumer perception was largely the result of preconceived notions about the operating system.

Test procedure
The Mojave Experiment is a public case study designed by Microsoft to determine computer users' thoughts of Windows Vista, in the absence of prior experience. The study begins by asking the participant's thoughts of Windows Vista, with their answers based solely on their knowledge from word of mouth. They were then asked to rate Windows Vista, from 0 to 10. Next, the participants were introduced to Windows "Mojave." This was Windows Vista, rebranded to prevent preconceived bias. The users were guided by a Microsoft assistant to test "Mojave." After the test, the participants were then asked to rate "Mojave," from 0 to 10. It was then revealed to the participants that "Mojave" was simply Windows Vista, rebranded.

Reception
Technology bloggers and journalists criticized the experiment, for several reasons, such as that the hardware and software were already set up, so the users did not have to install applications or device drivers, which were the typical source of compatibility issues.
