Mr. Robot and His Robot Factory. Mr. Robot and His Robot Factory is a platform game created for Atari 8-bit computers by Ron Rosen and published in 1983 by Datamost. The music was composed by Gary Gilbertson using Philip Price's Advanced Music Processor, while the title screen was drawn by Art Huff. It was ported to the Apple II by Robert McNally and to the Commodore 64.

The gameplay is similar to that of Miner 2049er (1982). The player controls a humanoid robot that must traverse all of the platforms in a factory filled with ladders, conveyor belts, and other gadgetry. There are 22 levels, plus a built-in level editor.

Gameplay

The robot is moved with either the keyboard or a joystick, and can make it walk side to side, climb up and down, and jump, collecting the white power pills from the platforms in the process. The player begins with four robots, and loses one if it falls too much or touches any of the fireball enemies. When one of the pulsing white rings scattered around the level is collected, the robot becomes temporarily invulnerable and can safely touch the fireballs, destroying them.

In each level the player begins with 100 units of energy and loses units at a rate of about one per second, making quick completion of each level important. When the energy runs out, the player loses a robot.

Points are granted in 10 point increments as the robot advances through the level. Collecting a ring earns 100 points, as does collecting the small musical note at the beginning of the level that turns off the game's sound effects. Dispatching a fireball is worth 500 points. Completing a level earns 100 points per unit of energy remaining on the screen.

Later levels include bombs and magnets. There are a total of 22 levels, not counting the 26 customized levels.

Reception
Mr. Robot and His Robot Factory was reviewed by Video magazine in its "Arcade Alley" column where it was compared to Miner 2049er and described as "sufficiently different [...] to represent an enthralling new test of skill". The reviewers praised the efforts of programmer Ron Rosen, noting that "the programming skill evidenced in the preparation of Mr. Robot is awesome" and concluding "what this game lacks in stark originality, it more than makes up for with polish". InfoWorld's Essential Guide to Atari Computers cited it as among the best Datamost games. It received a positive review in the German magazine Happy Computer.

CoreASM. CoreASM is an open source project (licensed under Academic Free License version 3.0) that focuses on the design of a lean executable ASM (Abstract State Machines) language, in combination with a supporting tool environment for high-level design, experimental validation, and formal verification (where appropriate) of abstract system models.

Abstract state machines are known for their versatility in modeling of algorithms, architectures, languages, protocols, and virtually all kinds of sequential, parallel, and distributed systems. The ASM formalism has been studied extensively by researchers in academia and industry for more than 15 years with the intention to bridge the gap between formal and pragmatic approaches. 

Model-based systems engineering can benefit from abstract executable specifications as a tool for design exploration and experimental validation through simulation and testing. Building on experiences with two generations of ASM tools, a novel executable ASM language, called CoreASM, is being developed (see CoreASM homepage). 

The CoreASM language emphasizes freedom of experimentation, and supports the evolutionary nature of design as a product of creativity. It is particularly suited to Exploring the problem space for the purpose of writing an initial specification. The CoreASM language allows writing of highly abstract and concise specifications by minimizing the need for encoding in mapping the problem space to a formal model, and by allowing explicit declaration of the parts of the specification that are purposely left abstract. The principle of minimality, in combination with robustness of the underlying mathematical framework, improves modifiability of specifications, while effectively supporting the highly iterative nature of specification and design.

CodeGear. CodeGear is a wholly owned division of Embarcadero Technologies. CodeGear develops software development tools such as the Delphi Integrated development environment, the programming language Delphi, and the database server InterBase. Originally a division of Borland Software Corporation, it was launched on 14 November 2006.

History
On 8 February 2006 Borland announced that it would seek a buyer for its IDE division and database products. During the spin-off negotiations, these divisions ("developer tools group") internally reorganized into a division called CodeGear.
Eventually, five parties bid for the group. However, no bidder offered Borland "numbers that appropriately reflected the value we think is in the business," according to a conference call with Borland CEO Tod Nielsen.

Borland's 2006 annual report showed that its CodeGear IDE business had sales of US$75.7 million in 2006, which accounted for 25 percent of Borland's total revenue.

On 7 May 2008, Borland Software Corporation and Embarcadero Technologies announced that Embarcadero had "signed a definitive asset purchase agreement to purchase CodeGear."

On 1 July 2008, Embarcadero Technologies announced the completed acquisition of CodeGear from Borland Software Corporation on 30 June 2008, for approximately $24.5 million.

Rod end bearing. A rod end bearing, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), is a mechanical articulating joint. Such joints are used on the ends of control rods, steering links, tie rods, or anywhere a precision articulating joint is required, and where a clevis end (which requires perfect 90-degree alignment between the attached shaft and the second component) is unsuitable. A ball swivel with an opening through which a bolt or other attaching hardware may pass is pressed into a circular casing with a threaded shaft attached. The threaded portion may be either male or female. The heim joint's advantage is that the ball insert permits the rod or bolt passing through it to be misaligned to a limited degree (an angle other than 90 degrees). A link terminated in two heim joints permits misalignment of their attached shafts (viz., other than 180 degrees).

History
The spherical rod end bearing was developed by Nazi Germany during World War II. When one of the first German planes to be shot down by the British in early 1940 was examined, they found this joint in use in the aircraft's control systems. Following this discovery, the Allied governments gave the H.G. Heim Company an exclusive patent to manufacture these joints in North America, while in the UK the patent passed to Rose Bearings Ltd. The ubiquity of these manufacturers in their respective markets led to the terms heim joint and rose joint becoming synonymous with their product. After the patents ran out the common names stuck, although  rosejoint remains a registered trademark of Minebea Mitsumi Inc., successor to Rose Bearings Ltd. Originally used in aircraft, the rod end bearing may be found in cars, trucks, race cars, motorcycles, lawn tractors, boats, industrial machines, go-karts, radio-control helicopters, formula cars, and many more applications.

Female heim joint 

Using female heim joints will allow users to make precise changes on key components of fixtures. One example of needing fine adjustment is within the helicopter’s adjustment of the blades. When using the adjustment, it is key to make sure it is in the correct spot or excessive wear will occur. This change allows quick adjustments that are easy with a female heim joint. When dealing with the pitch of a helicopter blades, heim joints are able to be adjusted to 0.010in. If spacing is critical, female heim joints are able to be threaded on, instead of welding inserts to the shaft. When dealing with aluminium shafts, the easiest way to use heim joints is to use the female heim joint. One example is using robots in robotics competitions. Light weight is a key factors when building competitive robots, so using aluminum rods and female heim joints can be key.  Another example using female heim joints is the shifter of motorcycles. The shifting mechanism allows forces to be applied linear, but still be able to work at angles when in different gears. Both male and female heim joints require the use of a lock nut after getting adjustment to correct specification needed.

IBM 2540. The IBM 2540 is a punched-card computer peripheral manufactured by IBM Corporation for use of System/360 and later computer systems. The 2540 was designed by IBM's Data Processing Division in Rochester, Minnesota, and was introduced in 1965.  The 2540 can read punched-cards at 1000 cards per minute (CPM) and punch at 300 CPM. The 2540 is based on the design of the older, slightly slower, 1402.

Description

The 2540 attaches to a System/360 multiplexer or selector channel through an IBM 2821 Control Unit. A standard 2540 processes standard IBM 80 column punched cards. The card reader (2540R) and card punch (2540P) devices are separately addressable and function independently. The 2540 normally reads and punches EBCDIC data, called data-mode 1.

Card reader
On the right side of the device is the reader, consisting of an input hopper holding approximately 3100 cards, and three output stackers (right to left – R1, R2, and RP3) each holding approximately 1350 cards. Cards can be directed to an output stacker under program control.

Card punch
On the left side of the device is the punch, with an input hopper holding about 1350 cards, and three output stackers (left to right – P1, P2, and RP3) each holding 1350 cards.  The center stacker (RP3) is shared between the reader and the punch, but is not intended to be used by both at the same time. Cards can be directed to an output stacker under program control.
The card is read after punching to ensure that the data was punched correctly.

Special features
 Column binary – this feature, data-mode 2, allows all possible combinations of holes to be read or punched in a column.
 Punch-feed-read – this feature allows input cards to be read by the punch unit and data simultaneously punched into the same card. This feature was not normally supported by spooling software.
 51-column Interchangeable Read Feed – this feature allows the 2540 to read 51-column "stub" cards in addition to standard 80-column cards.  Operator setup was required to change card size, so the two sizes could not be intermixed.  Installation of this feature reduced the capacities of stackers R1 and R2 to around 800 cards, and reduced read speed to 800 CPM.

Successors    
With the introduction of System/370 IBM announced the improved 3525 card punch and the 3505 card reader in 1971.

Excitation table. In electronics design, an excitation table shows the minimum inputs that are necessary to generate a particular next state (in other words, to "excite" it to the next state) when the current state is known. They are similar to truth tables and state tables, but rearrange the data so that the current state and next state are next to each other on the left-hand side of the table, and the inputs needed to make that state change happen are shown on the right side of the table.

Flip-flop excitation tables
In order to complete the excitation table of a flip-flop, one needs to draw the Q(t) and Q(t + 1) for all possible cases (e.g., 00, 01, 10, and 11), and then make the value of flip-flop such that on giving this value, one shall receive the input as Q(t + 1) as desired.

Motor launch (naval). A motor launch (ML) is a small military vessel in Royal Navy service. It was designed for harbour defence and submarine chasing. Similar vessels were used by the Royal Air Force for armed high-speed air-sea rescue. Some vessels for water police service are also known as motor launches.
Motor launches were slower than motor torpedo boats and motor gun boats

World War I service

Although small by naval standards, it was larger than the preceding steam or diesel-engined harbour launches of 56 ft and coastal motor boats of 40 and 55 ft length. The first motor launches entered service in the First World War. These were five hundred and eighty  vessels built by the US Elco company for the Admiralty, receiving the numbers ML-1 to ML-580. They served with the Royal Navy between 1916 and the end of the war, defending the British coast from German submarines. Some of the earliest examples, including ML 1, also served in the Persian Gulf from June 1916. After the Armistice of 11 November 1918 a flotilla of 12 Royal Navy motor launches travelled down the Rhine performing duty as the Rhine Patrol Flotilla. The only known surviving example of a World War I era motor launch is ML-286, which now lies in a poor condition on the banks of the River Thames.

World War II types

The BPBC Type Two was succeeded by the Type Three 68 ft "Hants and Dorset".

Post-war, many motor launches were taken on as pleasure boats. A number of them are on the National Register of Historic Vessels.
